Full Text Available Radical cystectomy remains the standard treatment for muscle-invasive carcinoma bladder. Various methods have been described for the urinary diversion. In the last 150 years urinary diversion has evolved from cutaneous ureterostomy to the orthotopic neobladder. Especially during the last 20 years, much advancement has been made. We hereby have reviewed the current approaches being used at different centers in India. We have also analyzed the evolution of diversion from conduit to the orthotopic substitution at our center.

We aimed to evaluate the risk factors of acute urinary retention (AUR) following robot-assisted radical prostatectomy (RARP), as well as the relationship of AUR with early continence outcomes. The records of 740 consecutive patients who underwent RARP by two experienced surgeons at our institution were retrospectively reviewed from a prospectively collected database. Multiple factors, including age, body mass index (BMI), international prostate symptom score (IPSS), prostate volume, presence of median lobe, nerve preservation status, anastomosis time, and catheter removal time (Day 4 vs. 7), were evaluated as risk factors for AUR using univariate and multivariate analysis. The relation between AUR and early return of continence (one and three months) post-RARP was also evaluated. The incidence of clinically significant vesico-urethral anastomotic (VUA) leak and AUR following catheter removal were 0.9% and 2.2% (17/740), respectively. In men who developed AUR, there was no significant relationship with regards to age, BMI, IPSS, prostatic volume, median lobe, nerve preservation, or anastomosis time; however, the incidence of AUR was significantly higher for men with catheter removal at Day 4 (4.5% [16/351]) vs. Day 7 (0.2% [1/389]) (p=0.004). Moreover, patients with early removal of the catheter (Day 4) who developed AUR had an earlier one-month return of 0-pad continence 87.5% (14/16) compared to patients without AUR 45.6% (153/335), with no significant difference at three months. While AUR is an uncommon complication of RARP, its incidence is much higher than VUA leakage. Further, it is often not well-discussed during patient counselling preoperatively. Moreover, earlier return of urinary continence was observed in patients experiencing AUR following RARP exclusively with catheter removal at Day 4. Future studies are warranted to validate the long-term impact of AUR on continence outcomes.

To describe the results of home exercise targeting the pelvic floor in continent women one year after the end of a physical therapy treatment for the following outcomes: functional assessment of the pelvic floor and urinary incontinence. This is an observational study that evaluated fifteen women one year after physical therapy treatment for Stress Urinary Incontinence (SUI). The outcomes for this study were: situations of urinary loss, use of daily protection, practice of home exercises for the pelvic floor, functional assessment of the pelvic floor (FAPF) and patient satisfaction. We also investigated some confounding variables such as hormonal status, number of vaginal deliveries and previous history of episiotomy. One year after completion of physical therapy treatment, we observed that the FAPF median remained stable over time (Median=5, p=0.08). The presence of urinary incontinence was reported by 40% of women in the sample, however, was characterized as mild (i.e. not requiring the use of daily protection). There was also a significant association (p=0.001) between the completion of home exercises (twice or more per week) and the normal clinical status. Confounding variables, which could compromise the clinical status, showed no significant association with the outcomes (p≥0.05). Home exercises contributed to the maintenance of continence following a physical therapy treatment.

[Physics of materials and female stress urinary continence: New concepts: I) Elasticity under bladder].

Guerquin, B

2015-09-01

Improving the understanding of the adaptation to stress of urinary continence. A transversal analysis between physics of materials and the female anatomy. Laws of physics of the materials and of their viscoelastic behavior are applied to the anatomy of the anterior vaginal wall. The anterior vaginal wall may be divided into two segments of different viscoelastic behavior, the vertical segment below the urethra and the horizontal segment below the bladder. If the urethra gets crushed on the first segment according to the hammock theory, the crushing of the bladder on the second segment is, on the other hand, damped by its important elasticity. The importance of this elasticity evokes an unknown function: damping under the bladder that moderates and delays the increase of intravesical pressure. This damping function below the bladder is increased in the cystocele, which is therefore a continence factor; on the other hand, it is impaired in obesity, which is therefore a factor of SUI. It is necessary to include in the theory of stress continence, the notion of a damping function below the bladder. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Contemporary surgical devices for male stress urinary incontinence: a review of technological advances in current continence surgery.

Chung, Eric

2017-07-01

Male stress urinary incontinence (SUI) remains a debilitating condition that adversely impacts all domains of quality of life and is associated with significant social stigma and health economic burden. The incidence of post-prostatectomy urinary incontinence (PPI) depends on the definition of urinary incontinence and the length of patient follow up. In patients with persistent PPI following failure of conservative measures, surgical treatment is recommended although there is no published guideline on when surgery should be performed, and what the best surgical option is. Male slings (MS) can be divided into adjustable or non-adjustable types, and offers an attractive option for patients who wish to avoid mechanical handling during urinary voiding. Published intermediate data supports good safety and efficacy rate in men with mild to moderate degree of SUI. The AMS 800 artificial urinary sphincter (AUS) remains the standard of treatment for complete continence and has the longest efficacy and safety records. Other AUS-like devices are designed to address current AMS 800 limitations but themselves are fraught with their own issues.

Full Text Available Aim of work: The aim of the study was to assess the diagnostic performance of static MR urography in detection of post cystectomy complications & the ability of static fluid MR urography in visualization of urinary tract segments. Material & methods: We prospectively reviewed 21 MR urograms with urinary diversion. The most common surgical procedures included Ileal conduit & Ileocecal neobladder diversion.Magnetic resonance urography examinations were performed with 1.5-T MR scanners. T2 weighted (static fluid MR urography techniques were done, in addition to conventional T1- and T2-weighted axial and coronal sequences. Urinary tract was divided in different parts: pelvicalyceal systems, upper, mid and lower ureteric segments & the reservoir or conduit Imaging features of the urinary collecting systems were evaluated for their visualization and complications detection. Results: T2-weighted MR urography could demonstrate 95% of urinary tract segments & together with conventional MR sequences all urinary tract segments can be visualized. Urinary diversion related complications were encountered included in 15 patients (71.4% & no urological complications were seen in 6 patients (28.6%. Conclusion: Comprehensive T2-weighted MR urography is an effective imaging method for the visualization of the urinary system and detection of early and late postoperative complications in patients with urinary diversion.

We compared two hypotheses as to why obesity is associated with stress urinary incontinence (SUI): (1) obesity increases demand on the continence system (e.g. higher cough pressure) and (2) obesity compromises urethral function and urethrovaginal support. A secondary analysis was performed using data from a case-control study of SUI in women. Measurements of urethrovaginal support (POP-Q point Aa, urethral axis), urethral function (maximal urethral closure pressure, MUCP), and measures of continence system demand (intravesical pressures at rest and during maximal cough) were analyzed. Cases and controls were divided into three body mass index (BMI) groups: normal (18.5-24.9 kg/m 2 ); overweight (25.0-29.9 kg/m 2 ); and obese (≥30 kg/m 2 ). Logistic regression models where created to investigate variables related to SUI for each BMI group. Structural equation modeling was used to test the direct and indirect relationships among BMI, SUI, maximal cough pressure, MUCP, and POP-Q point Aa. The study included 108 continent controls and 103 women with SUI. MUCP was the factor most strongly associated with SUI in all BMI groups. Maximal cough pressure was significantly associated with SUI in obese women (OR 3.191, 95% CI 1.326, 7.683; p continence mechanism.

Full Text Available Radical prostatectomy (RP is the most common cause of stress urinary incontinence (UI in men. Several anatomic structures affect or may affect urinary continence - urethral sphincter, levator ani muscle, puboprostatic ligaments, bladder neck, endopelvic fascia, neurovascular bundle - and understanding of the anatomy of pelvic floor and urethra is crucial for satisfactory functional outcome of the procedure. Surgical techniques implemented to improve continence rates include nerve-sparing procedure, bladder neck preservation/plication, urethral length preservation, musculofascial reconstruction, puboprostatic ligaments preservation or seminal vesicle preservation. Perioperative (preoperative and postoperative pelvic floor muscle training (PFMT aims to shorten the duration of postoperative UI and thus, improve early continence rates postoperatively. In the review, complex information regarding anatomical, intra- and perioperative factors affecting urinary continence after RP is provided, including description of important anatomical structures, possible implications for surgical technique and evaluation of different PFMT strategies in perioperative period.

Full Text Available Aim :Evaluate postoperative urinary continence in patients withcongenital adrenal hyperplasia(CAHwith intermediate (ITand high urogenital sinus (UGS who underwent a UGS mobilization maneuver .Methods: We called IT to those that although needing an aggressive dissection to get to the vagina, still have enough urethra proximal to the vaginal confluence. Very low variants are excluded from this analysis. Dissection always started in the posterior wall of the UGS with an aggressive separation from the anterior rectal wall. If the wide portion of the vagina was reached dissection stopped and the UGS opened ventrally widening to the introitus. Nineteen patients were treated using this maneuver (Group1. When more dissection was required the anterior wall of the UGS was dissected and carefully freed from the low retropubic space. Then the UGS was opened either ventrally or dorsally. Thirty three patients required this approach (Group 2 .Combined procedures were used in 3 patients with high UGS (Group 3. Results : Mean age at the time of the repair and length of the UGS were 12.2 years (4 months to 18 years and 3.75 cm (3 -8 cmfor G 1; 8 years (5 months to 17 years and 6.34 cm ( 4-12 cm in G2 and 8,3 years (2 -14 y and 11.5cm (11-12cm in G3. All patients had been regularly followed. Mean age at last follow up of 14.3y, 17y and 9.9y for groups 1, 2 and 3 respectively. All patients continue to void normally and are continent. All patients have 2 separate visible orifices in the vulva. Only 3 are sexually active.Conclusion: UGS mobilization for vaginoplasty in girls with CAH does not compromise voiding function or urinary continence,

We investigated the outcomes and quality of life measures in men who underwent cystectomy and urinary diversion for devastating lower urinary tract toxicity after prostatic radiotherapy and/or cryotherapy for the treatment of prostate cancer. Records of patients who underwent cystectomy and urinary diversion for the management of a devastated lower urinary tract following prostatic radiotherapy or cryotherapy were reviewed retrospectively. A postoperative, retrospective quality of life (QOL) survey was designed specific to this patient subset and obtained by telephone interview. Extirpative surgery with urinary diversion for management of a devastated lower urinary tract was performed on 15 patients with a mean age of 72 years (range 63-82). Toxicities leading to bladder removal included bladder neck contractures, prostatic necrosis, incontinence, osteomyelitis, bladder calculi, fistulae, urethral strictures, abscesses, necrotizing fasciitis, and radiation/hemorrhagic cystitis. The mean number of failed conservative, minimally invasive interventions per patients prior to cystectomy was 3.7 (range 1-12). The average time period from major complication following radiotherapy/cryotherapy to cystectomy was 29.1 months (range 5-65). The QOL survey showed all of the patients who completed the survey (n = 13) would undergo the procedure again and 11 (85%) would have undergone the procedure an average of 13.2 months sooner (range 5-36). Toxicities secondary to prostatic radiotherapy or cryotherapy may be debilitating. Our results demonstrate that cystectomy with urinary diversion can improve QOL in patients with a devastated lower urinary tract.

Plasmodium vivax is the geographically most widespread human malaria parasite. To analyze patterns of microsatellite diversity and population structure across countries of different transmission intensity, genotyping data from 11 microsatellite markers was either generated or compiled from 841 isolates from four continents collected in 1999-2008. Diversity was highest in South-East Asia (mean allelic richness 10.0-12.8), intermediate in the South Pacific (8.1-9.9) Madagascar and Sudan (7.9-8.4), and lowest in South America and Central Asia (5.5-7.2). A reduced panel of only 3 markers was sufficient to identify approx. 90% of all haplotypes in South Pacific, African and SE-Asian populations, but only 60-80% in Latin American populations, suggesting that typing of 2-6 markers, depending on the level of endemicity, is sufficient for epidemiological studies. Clustering analysis showed distinct clusters in Peru and Brazil, but little sub-structuring was observed within Africa, SE-Asia or the South Pacific. Isolates from Uzbekistan were exceptional, as a near-clonal parasite population was observed that was clearly separated from all other populations (FST>0.2). Outside Central Asia FST values were highest (0.11-0.16) between South American and all other populations, and lowest (0.04-0.07) between populations from South-East Asia and the South Pacific. These comparisons between P. vivax populations from four continents indicated that not only transmission intensity, but also geographical isolation affect diversity and population structure. However, the high effective population size results in slow changes of these parameters. This persistency must be taken into account when assessing the impact of control programs on the genetic structure of parasite populations.

Transverse colon conduit urinary diversion in patients treated with very high dose pelvic irradiation

1994-01-01

Urinary diversion may be required in patients receiving pelvic irradiation for gynaecological or genitourinary cancers either as part of a planned or salvage surgical procedure or for urological complications of irradiation. Records were reviewed for 30 such patients who underwent transverse colon conduit as a primary form of urinary diversion. Most of the conduits were constructed using refluxing ureterocolic anastomoses with stents. The results showed no operative mortality. Although the procedure was associated with a complication rate of 37% and a re-operation rate of 20%, there were no bowel or urinary anastomotic leaks. The operation could be safely performed on patients with renal failure, with 83% of such patients showing normal or improved serum creatinine levels post operatively. The advantages of transverse colon conduit urinary diversion are the use of non-irradiated bowel and ureters for diversion. It is recommended as a primary form of urinary diversion in these high risk cases. (Author)

Full Text Available Purpose We studied the influence of preoperative bladder outlet obstruction (BOO on postoperative continence rates and patient satisfaction after the midurethral sling procedure. Methods A total of 159 women who underwent the midurethral sling procedure were evaluated. Using the Blaivas-Groutz nomogram, we assigned the patients were assigned to Group I (n=37, no obstruction, Group II (n=89, mild obstruction, or Group III (n=33, moderate to severe obstruction. Continence rates, patient satisfaction, urinary sensation scale and uroflowmetry were evaluated postoperatively. Results There were no significant differences in continence rates, satisfaction, or postoperative maximal flow rate between the 3 groups. Postoperative urgency was improved after surgery in Groups I and II (P<0.05 but not in Group III. Conclusions BOO does not seem to be a risk factor for failure after the midurethral sling procedure. However, BOO may be considered as a potential factor for persistent storage symptoms after the midurethral sling.

Health-Related Quality of Life after Cystectomy and Urinary Diversion for Bladder Cancer

With multiple options for urinary diversion after radical cystectomy for bladder cancer that have comparable cancer control and complication rates, health-related quality of life (HRQOL) has become an important consideration. This article reviews the methods for defining HRQOL, the challenges in measuring HRQOL in bladder cancer, and the literature comparing HRQOL after various methods of urinary diversion. Recent contributions include the validation of HRQOL instruments specific to bladder cancer and the publication of several prospective studies measuring HRQOL outcomes after cystectomy and urinary diversion. There is no convincing evidence from existing literature that any particular method of urinary diversion offers superior HRQOL outcomes. Rather, there is growing evidence that good HRQOL can be achieved with patient education and consideration of each patient's clinical and psychosocial situation. Future research should utilize the validated bladder cancer specific HRQOL instruments and perhaps explore the impact of preoperative counseling on postoperative HRQOL. PMID:21826139

The aims of this study were to determine the diagnostic value of MR urography and to compare the T2- and T1-weighted MR urography techniques in patients with urinary diversion. We retrospectively reviewed 19 MR urograms in 14 patients (13 male and one female, 8–77 years old, mean age: 54.2) with urinary diversion. Magnetic resonance urography examinations were performed with 1.5-T MR scanners. In addition to T2- and T1-weighted MR urography techniques, conventional T1- and T2-weighted axial and coronal sequences were also obtained. Collecting systems were evaluated in five segments (right proximal and distal collecting system, left proximal and distal collecting system and conduit or reservoir). Imaging features of the urinary collecting systems were evaluated with T2- and T1-weighted MR urography images. The clinical, laboratory data and follow-up imaging findings were regarded as standard. A cross table was formed to determine sensitivity, specificity and accuracy of MR urography techniques. T2-weighted MR urography, T1-weighted MR urography and combination of these two techniques could demonstrate 89.01, 87.65 and 93.83% of all collecting system segments, respectively. For the detection of the pathologic urinary segments, sensitivity, specificity and accuracy were 100, 95.29 and 95.6% in T2-weighted MR urography and 100, 93.42 and 93.82% in T1-weighted MR urography, respectively. Sensitivity, specificity and accuracy were 100% in combined T2- and T1-weighted MR urography technique. Magnetic resonance urography is an effective imaging method for the evaluation of the urinary system in patients with urinary diversion. T2-weighted MR urography alone has high sensitivity, specificity and accuracy, does not require intravenous contrast medium and can be obtained in 3–5 min. However, T1-weighted MR urography may provide additional information in some cases.

The bioCarbon ureterostomy device is a stomal prosthesis for upper tract urinary diversion that has had preliminary successes in animal and human trials in Europe and Peru. Implantation of a pure carbon stomal prosthesis offers the potential advantages of high biocompatibility, lack of encrustation, and elimination of stomal stenosis which is frequently associated with cutaneous ureterostomy. Nine bioCarbon ureterostomy devices were implanted from August, 1984 through July, 1985. Although successful implantation was achieved in 2 patients, the complication rate was high. The bioCarbon ureterostomy device has potential as an alternative form of urinary diversion. However, significant problems need to be remedied before it can be recommended for routine clinical application.

We investigated the influence of bladder neck preservation on urinary continence, quality of life and surgical margins after radical prostatectomy. A total of 208 men who presented for radical prostatectomy were randomized to complete bladder neck preservation with subsequent urethro-urethral anastomosis or to no preservation as controls. Patients with failed bladder neck preservation were not included in study. We documented objective continence by the 24-hour pad test, social continence by the number of pads per day and quality of life outcomes by the validated Incontinence Quality of Life questionnaire in a single blind setting. Cancer resection was assessed by surgical margin status. At 0, 3, 6 and 12 months mean urine loss in the control vs the bladder neck preservation group was 713.3 vs 237.0, 49.6 vs 15.6, 44.4 vs 5.5 and 25.4 vs 3.1 gm, respectively (each p <0.001). At 3, 6 and 12 months in the control vs the preservation group the social continence rate was 55.3% vs 84.2% (p <0.001), 74.8% vs 89.5% (p = 0.05) and 81.4% vs 94.7% (p = 0.027), and the quality of life score was 80.4 vs 90.3 (p <0.001), 85.4 vs 91.7 (p = 0.016) and 86.0 vs 93.8 (p = 0.001), respectively. We noted significantly less urine loss, higher objective and social continence rates, and higher quality of life scores after complete bladder neck preservation at all followup points. On multiple logistic regression analysis complete bladder neck preservation was an independent positive predictor of continence. No significant difference was found in surgical margin status between the control and bladder neck preservation groups (12.5% vs 14.7%, p = 0.65). In what is to our knowledge the first prospective, randomized, controlled, single blind trial complete bladder neck preservation during radical prostatectomy was associated with a significantly higher urinary continence rate and increased patient satisfaction without compromising resection margins.

Tissue engineering and regenerative medicine (TERM) approaches may provide alternatives for gastrointestinal tissue in urinary diversion. To continue to clinically translatable studies, TERM alternatives need to be evaluated in (large) controlled and standardized animal studies. Here, we investigated all evidence for the efficacy of tissue engineered constructs in animal models for urinary diversion. Studies investigating this subject were identified through a systematic search of three different databases (PubMed, Embase and Web of Science). From each study, animal characteristics, study characteristics and experimental outcomes for meta-analyses were tabulated. Furthermore, the reporting of items vital for study replication was assessed. The retrieved studies (8 in total) showed extreme heterogeneity in study design, including animal models, biomaterials and type of urinary diversion. All studies were feasibility studies, indicating the novelty of this field. None of the studies included appropriate control groups, i.e. a comparison with the classical treatment using GI tissue. The meta-analysis showed a trend towards successful experimentation in larger animals although no specific animal species could be identified as the most suitable model. Larger animals appear to allow a better translation to the human situation, with respect to anatomy and surgical approaches. It was unclear whether the use of cells benefits the formation of a neo urinary conduit. The reporting of the methodology and data according to standardized guidelines was insufficient and should be improved to increase the value of such publications. In conclusion, animal models in the field of TERM for urinary diversion have probably been chosen for reasons other than their predictive value. Controlled and comparative long term animal studies, with adequate methodological reporting are needed to proceed to clinical translatable studies. This will aid in good quality research with the reduction in

The terminology for adult neurogenic lower urinary tract dysfunction (ANLUTD) should be defined and organized in a clinically based consensus Report. This Report has been created by a Working Group under the auspices and guidelines of the International Continence Society (ICS) Standardization Steering Committee (SSC) assisted at intervals by external referees. All relevant definitions for ANLUTD were updated on the basis of research over the last 14 years. An extensive process of 18 rounds of internal and external review was involved to exhaustively examine each definition, with decision-making by collective opinion (consensus). A Terminology Report for ANLUTD, encompassing 97 definitions (42 NEW and 8 CHANGED, has been developed. It is clinically based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different groups involved not only in lower urinary tract dysfunction but additionally in many other medical specialties. A consensus-based Terminology Report for ANLUTD has been produced to aid clinical practice and research. © 2017 Wiley Periodicals, Inc.

The purpose of this study was to determine if 3D-rendered CT urography (CTU) depicts both normal and abnormal findings in patients with urinary diversions and if the addition of contrast-enhanced CT digital radiography (CTDR) improves opacification of the urinary collecting system. Thirty CTU and contrast-enhanced CTDR examinations were performed in 24 patients who underwent cystectomy for bladder cancer. Indications for evaluation included hematuria, tumor surveillance, or suspected diversion malfunction. All examinations were evaluated without knowledge of the stage or grade of a patient's tumor and were compared with the clinical records. Opacification of the urinary collecting system was evaluated with 3D CTU alone, contrast-enhanced CTDR alone, and combined CTU and CTDR. Nine abnormalities were identified including distal ureteral strictures (n = 4), vascular compression of the mid left ureter (n = 1), scarring of the mid right pole infundibulum (n = 1), bilateral hydronephrosis and hydroureter (n = 1), urinary reservoir calculus (n = 1), and tumor recurrence invading the afferent limb of the neobladder (n = 1). Eight of the nine detected abnormalities were surgically or pathologically confirmed. All abnormalities were identified on all three imaging techniques but were best seen on 3D CTU and enhanced CTDR images. Incomplete opacification of the urinary collecting system occurred in 17 patients with CTU alone, 12 patients with contrast-enhanced CTDR alone, and nine patients with combined CTU and contrast-enhanced CTDR. Compared with CTU alone, the combined technique of 3D CTU and contrast-enhanced CTDR improved opacification by a statistically significant difference (p = 0.037). CTU with 3D rendering can accurately depict both normal and abnormal postoperative findings in patients with urinary diversions. Adding enhanced CTDR can improve visualization of the urinary collecting system.

Accurate determination of renal function in patients with intestinal urinary diversions

1986-01-01

The regular determination of renal function is a critical part of the management of patients who have had the urinary tract reconstructed with intestinal segments. These intestinal segments reabsorb urinary solutes and, thereby, complicate the determination of renal function by conventional methods. Urinary clearances of urea, creatinine and inulin were performed in patients with intestinal segments in the urinary tract and controls under varying diuretic conditions. Patients with intestinal diversions also underwent radioisotopic determination of renal function. The urinary clearances of urea, creatinine and inulin are highly dependent on the rate of urine flow in patients with intestinal segments in the urinary tract. Diuresis maximizes the urinary clearances of these solutes by minimizing intestinal reabsorption. Creatinine clearance prediction from the serum creatinine underestimates true glomerular filtration rate. Radioisotopic determination of renal function correlates poorly with true glomerular filtration rate. Only creatinine clearance measured under diuretic conditions correlates well with true renal function. Urine concentrating ability cannot be assessed accurately in patients with intestinal segments in the urinary tract, since osmolality rapidly equilibrates across the segments

Full Text Available The paper presents the technical characteristics of radical prostatectomy (RPE for early continence recovery in patients with prostate cancer. Restoration of the fascial structures of the small pelvis after RPE has been found to promote early urinary continence recovery. A method for total restoration of the fascial structures of the small pelvis (an operation after A. Tewari and a procedure for performing posterior suspension of urethrocystic neoanastomosis in Denonvilliers’ fascia length deficit are considered, which show the similar results in the time of continence recovery.

To evaluate the impact of metabolic syndrome on the early recovery of urinary continence after robot-assisted radical prostatectomy. The present study included a total of 302 consecutive Japanese patients with clinically localized prostate cancer who underwent robot-assisted radical prostatectomy. In this study, postoperative urinary continence was defined as no leak or the use of a security pad. The continence status was assessed by interviews before and 1 and 3 months after robot-assisted radical prostatectomy. Metabolic syndrome was defined as follows: body mass index ≥25 kg/m 2 and two or more of the following: hypertension, diabetes mellitus and dyslipidemia. The effect of the presence of metabolic syndrome on the continence status of these patients was retrospectively examined. A total of 116 (38.4%) and 203 (67.2%) of the 302 patients were continent at 1 and 3 months after robot-assisted radical prostatectomy, respectively. A total of 31 (10.3%) patients were judged to have metabolic syndrome. Despite the operative time being longer in patients with metabolic syndrome, no significant differences were observed in the remaining preoperative, intraoperative or postoperative variables between patients with or without metabolic syndrome. On multivariate logistic regression analysis, metabolic syndrome and the duration of hospitalization were significantly correlated with the 1-month continence status. Similarly, metabolic syndrome and estimated blood loss during surgery were independent predictors of continence rates at 3 months after robot-assisted radical prostatectomy. These findings suggest that the presence of metabolic syndrome could have a significant impact on the early recovery of urinary continence after robot-assisted radical prostatectomy. © 2017 The Japanese Urological Association.

To compare magnetic resonance imaging (MRI) of the pelvic floor musculature (PFM), bladder neck and urethral sphincter morphology under three conditions (rest, PFM maximal voluntary contraction (MVC), and straining) in older women with symptoms of stress (SUI) or mixed urinary incontinence (MUI) or without incontinence. This 2008-2012 exploratory observational cohort study was conducted with community-dwelling women aged 60 and over. Sixty six women (22 per group), mean age of 67.7 ± 5.2 years, participated in the study. A 3 T MRI examination was conducted under three conditions: rest, PFM MVC, and straining. ANOVA or Kruskal-Wallis tests (data not normally distributed) were conducted, with Bonferroni correction, to compare anatomical measurements between groups. Women with MUI symptoms had a lower PFM resting position (M-Line P = 0.010 and PC/H-line angle P = 0.026) and lower pelvic organ support (urethrovesical junction height P = 0.013) than both continent and SUI women. Women with SUI symptoms were more likely to exhibit bladder neck funneling and a larger posterior urethrovesical angle at rest than both continent and MUI women (P = 0.026 and P = 0.008, respectively). There were no significant differences between groups on PFM MVC or straining. Women with SUI and MUI symptoms present different morphological defects at rest. These observations emphasize the need to tailor UI interventions to specific pelvic floor defects and UI type in older women. Older women with UI demonstrate different problems with their pelvic organ support structures depending on the type of UI. These new findings should be taken into consideration for future research into developing new treatment strategies for UI in older women. Neurourol.

Baldwin, Andrew H; Jensen, Kai; Schönfeldt, Marisa

2014-03-01

Atmospheric warming may influence plant productivity and diversity and induce poleward migration of species, altering communities across latitudes. Complicating the picture is that communities from different continents deviate in evolutionary histories, which may modify responses to warming and migration. We used experimental wetland plant communities grown from seed banks as model systems to determine whether effects of warming on biomass production and species richness are consistent across continents, latitudes, and migration scenarios. We collected soil samples from each of three tidal freshwater marshes in estuaries at three latitudes (north, middle, south) on the Atlantic coasts of Europe and North America. In one experiment, we exposed soil seed bank communities from each latitude and continent to ambient and elevated (+2.8 °C) temperatures in the greenhouse. In a second experiment, soil samples were mixed either within each estuary (limited migration) or among estuaries from different latitudes in each continent (complete migration). Seed bank communities of these migration scenarios were also exposed to ambient and elevated temperatures and contrasted with a no-migration treatment. In the first experiment, warming overall increased biomass (+16%) and decreased species richness (-14%) across latitudes in Europe and North America. Species richness and evenness of south-latitude communities were less affected by warming than those of middle and north latitudes. In the second experiment, warming also stimulated biomass and lowered species richness. In addition, complete migration led to increased species richness (+60% in North America, + 100% in Europe), but this higher diversity did not translate into increased biomass. Species responded idiosyncratically to warming, but Lythrum salicaria and Bidens sp. increased significantly in response to warming in both continents. These results reveal for the first time consistent impacts of warming on biomass and

The authors performed diuretic renography in 17 patients with pelvic malignancy and urinary tract diversion. After injection of 10 mCi of Tc-99m-labeled DTPA, perfusion and dynamic images of renal function were obtained. Patients received furosemide, 0.5 mg/kg intravenously, 20-21 minutes into the study. Background subtracted whole-kidney time activity curves were generated. Studies were interpreted as normal, intermediate, or obstructed, depending on the contour of the washout phase of the renogram. In the immediate postoperative period, 82% of patients showed an intermediate pattern. In these patients with urinary diversion procedures, the standard criterion of a half-life of 10 minutes or less could not be used. Instead, serial studies over time best separated patients into three groups: normal, dilated without obstruction, and obstruction. Diuretic renography is useful in the follow-up of patients who have undergone urinary diversion procedures

Objective: To compare the results of suprapubic with transurethral urinary diversion in hypospadias repair. Data Source: Patients admitted to the Department of Urology and Renal Transplantation with distal or middle hypospadias. Design of Study: Randomized Controlled Trials. Setting: Department of Urology and Renal Transplantation, Quaid-I-Azam Medical College /Bahawal Victoria Hospital, Bahawalpur. Period: From June 2010 to December 2011. Materials and Methods: A total of sixty patients, 1 to 10 years of age with distal or middle hypospadias were included in the study. Patients with history of previous hypospadias repair were excluded. Patients were divided in two groups by using random numbers table, 30 patients in each group. Group I had suprapubic and Group II had transurethral urinary diversion. Tubularized Incised Plate urethroplasty and Mathieu's repair were commonly used techniques. Stent was kept for 7-14 days. Patient discharged from hospital at 72 hours post-operatively with urethral catheter or suprapubic cystostomy intact. Patients were followed for subsequent outcome. Follow up was initially fortnightly and then at 1 month intervals. Minimum follow up period was 3 months and maximum 18 months for these particular patients. Results: Only two patients of Group I had complications as compared to seven patients of Group II. Moreover, patient discomfort and voiding problems was more with group II than group I. Nursing care was easy in group I patients. Complication rate was significantly 10 where in group I as compared to group II. Conclusion: The overall complication rate and patient discomfort were significantly lower with suprapubic urinary diversion in hypospadias repair, which also had a better cosmetic outcome. (author)

Edmond P H Choi

Full Text Available The aim of this study was to evaluate whether community-based nurse-led continence care interventions are effective in improving outcomes for adult Chinese primary care patients with lower urinary tract symptoms (LUTS.A case-controlled intervention study was conducted. An intervention group of 360 primary care patients enrolled into a nurse-led continence care programme were recruited by consecutive sampling. A control group of 360 primary care patients with LUTS identified by screening were recruited from the waiting rooms of primary care clinics by consecutive sampling. Both groups were monitored at baseline and at 12 months.Outcome measures included symptom severity, health-related quality of life (HRQOL, self-efficacy, global health and self-reported health service utilization at 12-months. The effect of the continence care programme on symptom severity and HRQOL was assessed by the difference-in-difference estimation, using independent t-test and multiple liner regression. Chi-square test was used to compare the self-efficacy, global health and self-reported health service utilization between the two groups at 12-months.After adjusting for baseline severity and socio-demographics, the intervention group had significant improvements in LUTS severity (P<0.05 and HRQOL (P<0.05. Improvements in the amount of urine leakage were not significantly different between the two groups. A higher proportion of subjects in the intervention group reported increased self-efficacy (43.48% vs. 66.83%, improved global health condition (17.74% vs. 41.5%, having doctor consultation (18.5% vs. 8.06, having medication due to LUTS (26.50% vs.11.29% and having non-drug therapy due to LUTS (59.5% vs.9.68%.Community-based nurse-led continence care can effectively alleviate symptoms, improve health-related quality of life, and enhance self-efficacy and the global health condition of Chinese male and female primary care patients with LUTS.

Al-Mandeel, H; Al-Badr, A

2013-08-01

Pelvic organ prolapse (POP) and stress urinary incontinence (SUI), are two common health-related conditions, each affecting up to 50% women worldwide. Stress urinary incontinence only observed after the reduction of co-existent prolapse is called occult SUI (OSUI), and is found in up to 80% of women with advanced POP. Although there is no consensus on how to diagnose OSUI, there are several reported methods to better diagnose. Counseling symptomatically continent women with POP concerning the potential risk for developing SUI postoperatively cannot be overstated. Evidence suggests that positive OSUI in symptomatically continent women who are planning to have POP repair is associated with a high risk of POSUI, furthermore, adding continence procedure is found to reduce postoperative SUI. Therefore, adding continence surgery at the time of POP surgery in patients who are found to have OSUI preoperatively is advocated.

There is a large interest in developing tissue engineered urinary diversions (TEUDs) in order to reduce the significant morbidity that results from utilization of the alimentary tract in the urinary system. Preclinical trials have been favorable but durable clinical results have not been realized. The present article will review the pertinent concepts for the clinical development of a successful TEUD. Studies continue to identify novel scaffold materials and cell populations that are combined to generate TEUDs. Scaffold composition range from synthetic material to decelluarized bladder tissue. Cell types vary from fully differentiated adult populations such as smooth muscle cells isolated from the bladder to stem cell populations including mesenchymal stem cells and induced pluripotent stem cells. Each scaffold and cell type has its advantages and disadvantages with no clear superior component having been identified. Recent clinical trials have been disappointing, supporting the need for additional investigation. Successful application of TEUDs requires a complex interplay of scaffold, cells, and host environment. Studies continue to investigate candidate scaffold materials, cell populations, and combinations thereof to determine which will best recapitulate the complex structure of the human genitourinary tract.

Full Text Available Tamer Abdin,1 Gideon Zamir,2 Alon Pikarsky,2 Ran Katz,1 Ezekiel H Landau,1 Ofer N Gofrit1 1Department of Urology, 2Department of General Surgery, Hadassah Hebrew University Hospital, Jerusalem, Israel Aim: To report on a simple and rapid method of urinary diversion. This method was applied successfully in different clinical scenarios when primary reconstruction of the ureters was not possible. Materials and methods: The disconnected ureter is catheterized by a feeding tube. The tube is secured with sutures and brought out to the lateral abdominal wall as cutaneous tube ureterostomy (CTU. Results: This method was applied in three different clinical scenarios: a 40-year-old man who sustained multiple high-velocity gunshots to the pelvis with combined rectal and bladder trigone injuries and massive bleeding from a comminuted pubic fracture. Damage control included colostomy and bilateral CTUs. A 26-year-old woman had transection of the right lower ureter during abdominal hysterectomy. Diagnosis was delayed for 3 weeks when the patient developed sepsis. The right kidney was diverted with a CTU. A 37-year-old male suffered from bladder perforation and hemorrhagic shock. Emergency cystectomy was done and urinary diversion was accomplished with bilateral CTUs. In all cases, effective drainage of the urinary system was achieved with normalization of kidney function. Conclusion: When local or systemic conditions preclude definitive repair and damage control surgery is needed, CTU provides fast and effective urinary diversion.

To revaluate ileocolonic pouch for ortho-topic neobladder reconstruction, a cohort of patients with bladder cancer was selected to undergo radical cystectomy and modified Le Bag pouch. Evaluation concentrates on continence and associated morbidity observed on close follow-up. Patients and Methods: A total of 37 patients including 16 females with T2 3 bladder cancer (19 transitional, 15 : squamous and 3 adenocarcinoma) were treated by radical cystectomy and totally detubularized ileocolic neobladder. Post operative morbidity, continence and urodynamic studies were evaluated. Mean time to have full daytime continence was tested against age, gender, postoperative complications, technique of pouch creation either stapler or hand suture and adjuvant irradiation. Results: Cystometry 12 months post surgery showed 493 ml median capacity with basal and maximum reservoir median pressures of 16 and 38 cm H 2 O respectively. Uro-flowmetry had maximum voiding volume of 370ml, voiding time 45s and maximum flow rate of 11.6ml/s. Within the first 2 months post operative 44% were continent by day, 33% by night and 67% had stress incontinence. By 12 months post surgery 89% were continent by day, 73% by night and 27% had stress incontinence. Two years post surgery 94% were continent by day and 81 % had complete day and night control of uri-ne. Urinary leakage was the most frequent early complication (10.8%). Late complications were urinary tract infection (13.5%), metabolic acidosis (13.5%) and reflux (10.8%). Pouch over distension (5.4%) was consistent with bladder neck obstruction. Patient's gender and postoperative morbidity were statistically significant factors to increase the mean time to continence; whereas, age, use of stapler and adjuvant radiotherapy had no significant effect. Conclusion: Modified Le Bag pouch is a simple technique with adequate pouch capacity that offers excellent slowly progressing continence rates with minor morbidity rate. Post operative morbidity and

Diagnosis and management of urinary incontinence and functional fecal incontinence (encopresis) in children.

The ability to maintain normal continence for urine and stools is not achievable in all children by a certain age. Gaining control of urinary and fecal continence is a complex process, and not all steps and factors involved are fully understood. While normal development of anatomy and physiology are prerequisites to becoming fully continent, anatomic abnormalities, such as bladder exstrophy, epispadias, ectopic ureters, and neurogenic disturbances that can usually be recognized at birth and cause incontinence, will require specialist treatment, not only to restore continence but also to preserve renal function. Most forms of urinary incontinence are not caused by an anatomic or physiologic abnormality and, hence, are more difficult to diagnose and their management requires a sound knowledge of bladder and bowel function.

Wollin, Judy; Bennie, Mary; Leech, Christine; Windsor, Carol; Spencer, Nancy

The study described in this article aimed to identify issues relating to incontinence and assess the impact of referral to a continence adviser on the lives of people with multiple sclerosis (MS). The study design used an in-depth, two-phase anonymous mail survey within a general community as nominated by the participants. Fifty-six people participated in phase 1 and eleven people completed phase 2. The results indicated that incontinence is a problem for the vast majority of participants--people with MS. One-third of the eligible participants took up the option of a consultation, assessment and treatment from a continence nurse. Reasons for not taking up the visit from the continence nurse included 'managing OK', 'didn't think it would help', 'embarrassed' and 'too busy'. Increasing awareness of urinary incontinence in the community is important and education needs to focus on at-risk groups in presenting the range of options available to assist people experiencing incontinence.

Patients with long-term indwelling catheters are at high risk of catheter-associated urinary tract infection (CAUTI). We hypothesized that colonizing the bladder with a benign Escherichia coli strain (E. coli HU2117, a derivative of E. coli 83972) would prevent CAUTI in older, catheterized adults. Adults with chronic, indwelling urinary catheters received study catheters that had been pre-coated with E. coli HU2117. We monitored the cultivatable organisms in the bladder for 28 days or until loss of E. coli HU2117. Urine from 4 subjects was collected longitudinally for 16S rRNA gene profiling. Eight of the ten subjects (average age 70.9 years) became colonized with E. coli HU2117, with a mean duration of 57.7 days (median: 28.5, range 0-266). All subjects also remained colonized by uropathogens. Five subjects suffered invasive UTI, 3 febrile UTI and 2 urosepsis/bacteremia, all associated with overgrowth of a urinary pathogen. Colonization with E. coli HU2117 did not impact bacterial bladder diversity, but subjects who developed infections had less diverse bladder microbiota. Colonization with E. coli HU2117 did not prevent bladder colonization or subsequent invasive disease by uropathogens. Microbial diversity may play a protective role against invasive infection of the catheterized bladder. ClinicalTrials.gov, NCT00554996 http://clinicaltrials.gov/ct2/show/NCT00554996.

Full Text Available Background. The highest rate of incontinence after radical prostatectomy (RP is observed in the first 2–6 months after surgery. In order  to decrease the period of incontinence, virous surgical methods aimed at preservation and reconstruction of structures participating  in the mechanism of urine retention has been developed and improved.The study objective is to evaluate effectiveness of an original method of formation of an urethral anastomosis in the early continence recovery.Materials and methods. Data on 126 patients who underwent retropubic RP were analyzed. Depending on the method of urethral anastomosis formation, patients were divided into 2 groups: in the 1st group (n = 52 the patients underwent PR with urethra suspension m. levator ani, in the 2nd (n = 74 – standard RP. In the 1st group, 6 ligatures were applied to the anterior and posterior urethra walls: at the 12 and 6 hour projections through the mucosa, submucosa, and smooth muscle; at the 10, 2, 4, and 8 hour projections – more laterally with capture of the m. levator ani medial margins. Continence recovery was evaluated on days 1, 7, and 14 after urinary catheter removal and then at days 30, 90, 180, and 365 after RP. The criteria of continence were absence of urine leakage at rest and during physical activity and a necessity of using a safety liner.Results. There weren’t any significant differences at day 1 after urinary catheter removal between the two groups (р > 0.05. In the 1st group, continence values at days 30, 90, and 180 after RP were significantly higher (57.7, 69.2, and 71.1 %, respectively compared to the 2nd group (35.1, 41.9, and 51.3 %, respectively (р <0.05.Conclusion. Results of this work show significant benefits of RP with urethra suspension m. levator ani compared to standard RP per continence recovery criteria at days 7, 14, 30, 90, and 180 after the surgery. The technique of urethra suspension m. levator ani is easy to perform and ensures

To compare the pelvic floor function between women with and without stress urinary incontinence after vaginal delivery. Seventeen women (age 35.5 ± 3.5) were prospectively studied at about 6 weeks, 3 months, and 6 months after vaginal delivery. Urinary incontinence was assessed by the International Consultation on Incontinence Questionnaire - Short Form. Pelvic floor function was assessed by antero-posterior diameter of the levator hiatus using transperineal ultrasound. Five of 17 women experienced postpartum stress urinary incontinence. The antero-posterior diameter of the levator hiatus at rest was significantly longer in stress urinary incontinent women than in continent women until 3 months after delivery (p continent women and stress urinary incontinent women. Regardless of urinary incontinence, the antero-posterior diameter of the levator hiatus at rest shortened at 6 months postpartum, compared to 6 weeks postpartum (p continent women by 6 months postpartum (p = 0.02). The extended pelvic floor may be a cause of stress urinary incontinence in the postpartum period. Therefore, treatment to improve the extended pelvic floor should be developed for the prevention of stress urinary incontinence.

We review our outcomes and experience of artificial urinary sphincter implantation for patients with refractory urinary incontinence from different causes. Between April 2002 and May 2017, a total of 32 patients (median age, 40.8 years) with urinary incontinence had undergone artificial urinary sphincter placement during urinary tract reconstruction. Eighteen patients (56.3%) were urethral injuries associated urinary incontinence, 9 (28.1%) had neurogenic urinary incontinence and 5 (15.6%) were post-prostatectomy incontinence. Necessary surgeries were conducted before artificial urinary sphincter placement as staged procedures, including urethral strictures incision, sphincterotomy, and augmentation cystoplasty. The mean follow-up time was 39 months. At the latest visit, 25 patients (78.1%) maintained the original artificial urinary sphincter. Four patients (12.5%) had artificial urinary sphincter revisions. Explantations were performed in three patients. Twenty-four patients were socially continent, leading to the overall success rate as 75%. The complication rate was 28.1%; including infections (n = 4), erosions (n = 4), and mechanical failure (n = 1). The impact of urinary incontinence on the quality of life measured by the visual analogue scale dropped from 7.0 ± 1.2 to 2.2 ± 1.5 (P urinary sphincter implantation in our center are unique, and the procedure is an effective treatment as a part of urinary tract reconstruction in complicated urinary incontinence cases with complex etiology.

To evaluate the influence of preservation of the muscular internal sphincter and proximal urethra on continence recovery after radical prostatectomy. This was a prospective single-center, case-control study. A total of 40 consecutive patients with organ-confined prostate cancer were submitted to radical prostatectomy with the preservation of the muscular internal sphincter and the proximal urethra (group 1), and their outcomes were compared with those of 40 patients submitted to a standard procedure (group 2). Continence rates were assessed using a self-administrated questionnaire at 3, 7 and 30 days, and 3 and 12 months after removal of the catheter. Group 1 had a faster recovery of early continence than group 2 at day 3 (45% vs 22%; P = 0.029) and at day 7 (75% vs 50%; P = 0.018). Considering the number of pads, group 1 had a faster recovery of continence at 3, 7 and 30 days, and also had less incidence of severe incontinence. There was no statistically significant difference in terms of continence at 3 and 12 months among the two groups. Multivariate logistic regression analysis showed that surgical technique and young age were significantly associated with earlier time to continence at 3 and 7 days. The two groups had no significant differences in terms of surgical margins. Our modified technique of radical retropubic prostatectomy with preservation of the smooth muscular internal sphincter, as well as of the proximal urethra during bladder neck dissection, results in a significantly increased urinary continence at 3, 7 and 30 days after catheter removal, with a minor incidence of severe incontinence. The technique is also oncologically safe, and it does not increase the operative duration of the procedure. © 2013 The Japanese Urological Association.

Outbreaks of zoonotic diseases in humans and livestock are not uncommon, and an important component in containment of such emerging viral diseases is rapid and reliable diagnostics. Such methods are often PCR-based and hence require the availability of sequence data from the pathogen. Rattus norvegicus (R. norvegicus) is a known reservoir for important zoonotic pathogens. Transmission may be direct via contact with the animal, for example, through exposure to its faecal matter, or indirectly mediated by arthropod vectors. Here we investigated the viral content in rat faecal matter (n=29) collected from two continents by analyzing 2.2 billion next-generation sequencing reads derived from both DNA and RNA. Among other virus families, we found sequences from members of the Picornaviridae to be abundant in the microbiome of all the samples. Here we describe the diversity of the picornavirus-like contigs including near-full-length genomes closely related to the Boone cardiovirus and Theiler's encephalomyelitis virus. From this study, we conclude that picornaviruses within R. norvegicus are more diverse than previously recognized. The virome of R. norvegicus should be investigated further to assess the full potential for zoonotic virus transmission.

During this prospective study we analyzed the effects of radical retropubic prostatectomy (RRP) on bladder and sphincter function by comparing preoperative and postoperative urodynamic data. The aim of the study was to determine the reason for urinary incontinence after RRP and explain why one group of patients will be immediately continent after catheter removal, while others need some time to reach complete continence. Urodynamic examination was performed in 63 patients 3-7 days before and 2 months after surgery. Forty-three (68.2%) and 53 (84.1%) patients regained continence at 2 and 9 months following RRP, respectively. Ten patients (15.9%) were immediately continent after catheter removal. Urodynamic stress incontinence was detected in 18 (28.6%), and detrusor overactivity incontinence in 2 (3.2%) patients 2 months after surgery. The amplitude of preoperative maximal voluntary sphincteric contractions was significantly higher in the postoperative continent group (125 vs. 96.5 cmH(2)O, P continent following catheter removal had no lower urinary tract symptoms (LUTS) and urodynamic abnormality preoperatively, and they had significantly higher preoperative and postoperative maximum urethral closure pressure (at rest and during voluntary sphincter contraction) than those who became continent later on. These data suggest that the main cause of incontinence after RRP is sphincteric weakness. In the continent group, those who became immediately continent had significantly higher maximum urethral closure pressure values at rest and at voluntary sphincteric contraction even before the surgery.

Full Text Available Objective: To evaluate prevalence and risk factors of fecal and urinary incontinence (UI in Brazilian women. Material and Methods: 685 women older than 20 years of age answered a questionnaire about urinary and fecal symptoms, clinical and obstetric antecedents. They were grouped according to presence or absence of UI. Results: Urinary and fecal incontinence was reported in 27% and 2% of cases, respectively. Mean age of incontinent women was significantly higher than continent ones. Incontinent women had a mean number of micturitions significantly higher than the continent ones. On average, incontinent women had higher rate of pregnancies and vaginal delivery when compared to the continent ones. Body mass index (BMI was significantly higher in incontinent participants and in women with no UI complaints (27.35 vs. 24.95, p < 0.05. Fecal incontinence prevalence was 2% and occurred exclusively in patients with UI. Conclusions: Vaginal delivery and high BMI have been identified as risk factors for UI development while aging and number of pregnancies may be correlated factors.

The function of the lower urinary tract is basically storage of urine in the bladder and the at-will periodic evacuation of the stored urine. Urinary incontinence is one of the most common lower urinary tract disorders in adults, but especially in the elderly female. The urethra, its sphincters, and the pelvic floor are key structures in the achievement of continence, but their basic anatomy is little known and, to some extent, still incompletely understood. Because questions with respect to continence arise from human morbidity, but are often investigated in rodent animal models, we present findings in human and rodent anatomy and histology. Differences between males and females in the role that the pelvic floor plays in the maintenance of continence are described. Furthermore, we briefly describe the embryologic origin of ureters, bladder, and urethra, because the developmental origin of structures such as the vesicoureteral junction, the bladder trigone, and the penile urethra are often invoked to explain (clinical) observations. As the human pelvic floor has acquired features in evolution that are typical for a species with bipedal movement, we also compare the pelvic floor of humans with that of rodents to better understand the rodent (or any other quadruped, for that matter) as an experimental model species. The general conclusion is that the "Bauplan" is well conserved, even though its common features are sometimes difficult to discern.

Assessment and management of urinary incontinence in women.

Urinary incontinence is a common and usually hidden issue that can affect women of all ages. It is often ignored by the patient because of their misconception that incontinence is an inevitable consequence of ageing and their low expectations of successful treatment. There are various types of incontinence, with symptoms that can significantly affect patients' quality of life. This article aims to enhance nurses' understanding of the types of urinary incontinence affecting women, associated risk factors and continence assessment, as well as the initial investigations and conservative treatments that can be instigated by general nurses. It also discusses some of the advanced treatments offered by specialist services. The article emphasises the importance of undertaking a holistic continence assessment to ensure appropriate continence care is provided, and how tailoring this care to the individual can improve adherence to treatment plans. © 2018 RCN Publishing Company Ltd.

The purpose of this descriptive study was to describe health-related quality of life (HRQOL) concerns among cancer patients with continent urinary diversion (UD) and incontinent UD. Study participants were accrued from members of the California United Ostomy Association and 2 cancer centers in Southern California. The City of Hope HRQOL-Ostomy Questionnaire (COHHRQOL-O) is a modified HRQOL measurement tool based on the original work done over a number of years by Grant and colleagues. The COHHRQOL-O was mailed to 2,890 individuals. Of the 1,600 returns, there were 307 responses from patients with UD, indicating that they had a UD and a diagnosis that clearly indicated cancer. The majority of respondents were diagnosed with bladder cancer, and the average time since surgery was 9.5 years. While most patients reported being sexually active prior to UD, less than 27% resumed sexual activity after surgery. More than 75% of patients also reported difficulty in adjusting to their UD, with the majority reporting difficulty with urine leakage. Those who were incontinent reported a range of bothersome issues, such as skin problems around the UD, difficulties in managing UD care, fear of recurrence, financial worries, family distress, and uncertainty about the future. The results of this study add to our understanding of how patients adjust to a UD and what problems and issues can occur, even years after the initial surgery. Mastering UD care is best done under the guidance of a WOC nurse, and access to WOC nurse is essential when problems occur.

Full Text Available A normal development of lower urinary tract function control evolves from involuntary bladder empting (incontinence during infancy to daytime urinary continence, and finally a successful day and night continence that is generally achieved by the 5th to 7th year of age. This gradual process primarily depends on the progressive maturation of the neural control of the lower urinary tract, but it is also influenced by behavioral training that evolves through social support. Functional voiding disorders (bladder dysfunction are common problems during childhood. They are present in 5-15 % of general pediatric population, and in one-fifth of school-age children or in over one-third of patients of the pediatric urologist or nephrologist. More than half of children with bladder dysfunction have vesicoureteral reflux, and more than two-thirds have recurrent urinary tract infections. There is also a frequent association of bladder dysfunction with constipation and encopresis (dysfunctional elimination syndrome. Bladder dysfunction may cause a permanent damage to the upper urinary tract and kidneys. In addition, urinary incontinence, as the most common manifestation of bladder dysfunction can be the cause of major stress in schoolage children and have a negative effect on the child’s feeling of self-esteem. Thus, a timely detection and treatment of this group of disorders in children is highly significant.

To assess the chronological changes in urinary incontinence and urethral function before and after radical prostatectomy (RP), and to compare the findings of pelvic magnetic resonance imaging (MRI) before and after RP to evaluate the anatomical changes. In total, 185 patients were evaluated with regard to the position of the distal end of the membranous urethra (DMU) on a mid-sagittal MRI slice and urethral sphincter function using the urethral pressure profilometry. The patients also underwent an abdominal leak point pressure test before RP and at 10 days and 12 months after RP. The results were then compared with the chronological changes in urinary incontinence. The MRI results showed that the DMU shifted proximally to an average distance of 4 mm at 10 days after RP and returned to the preoperative position at 12 months after RP. Urethral sphincter function also worsened 10 days after RP, with recovery after 12 months. The residual length of the urethral stump and urinary incontinence were significantly associated with the migration length of the DMU at 10 days after RP. The residual length of the urethral stump was a significant predictor of urinary incontinence after RP. This is the first study to elucidate that the slight vertical repositioning of the membranous urethra after RP causes chronological changes in urinary incontinence. A long urethral residual stump reduces urinary incontinence after RP. © 2018 The Authors BJU International © 2018 BJU International Published by John Wiley & Sons Ltd.

Implants of pure carbon are ideal for prosteses because of their tissue acceptability and lack of incrustation. Animal experiments with biocarbon implants were tested as subfascial implantations, coeco-, ileo-, and vesicostomies, (n = 37). The results showed lack of reaction and good healing of the stomata, lack of incrustation, and water tight urinary diversion. Based on these animal experiments biocarbon vesicostomies were carried out successfully in six patients. The follow up period was 3--16 months.

To better understand clinically significant definitions of urinary incontinence we investigated the relationship between urinary leakage and patient reported bother from urinary leakage. A consecutive series of 1,411 men who underwent radical prostatectomy at Karolinska University Hospital, Stockholm, Sweden, from 2002 to 2006 were invited to complete a study specific questionnaire with questions on pad status, urinary leakage and bother from urinary leakage. Questionnaires were received from 1,179 men with a followup of greater than 1 year (median 2.2). Results showed that even a small amount of urinary leakage resulted in a high risk of urinary bother. Of 775 survivors 46 (6%) reporting 0 pads indicated moderate or much bother compared to 38 of 123 (31%) who reported using a security pad. When comparing the 2 groups, the risk of bother from urinary leakage was more than 5 times higher in the safety pad vs the 0 pad group (RR 5.2, 95% CI 3.5-7.7). As the number of pads increased, we noted a higher bother risk. Cross-tabulation of pad use and urinary leakage revealed wide variation in pad requirements despite the same answer to urinary leakage questions. If the definition of continence is based on pad use, for example safety pads, a certain number of men who report moderate or much bother from urinary leakage will be defined as continent. Our results also show that for each stated rate of urinary leakage men prove to have a major variation in the pad requirement.

Full Text Available Abstract Background The association of ureterosigmoidostomy with colonic cancer is well established. A 100-fold increased risk of malignancy has been proposed in association with ureterosigmoidostomy. Characteristically there is a latent period of around 20–30 years before the occurrence of cancer. Case presentation An unusual case of adenocarcinoma of the colon in a 36-year-old patient is presented. The patient underwent three operations in his infancy for exstrophy but after failure to close bladder, ureterosigmoidostomy was attempted at the age of 5 years and was converted to an ileal conduit after 8 months. At the age of 36 years, 30 years following ileal conduit urinary diversion for exstrophy, he presented in emergency with large bowel obstruction due to adenocarcinoma of the sigmoid colon. Conclusion Patients who undergo urinary diversion for exstrophy may be kept on a regular follow-up surveillance colonoscopy as most of these young adults may later present with vague abdominal symptoms which may not be taken seriously until they increase to an extent as to present with intestinal obstruction as in the present case.

The aim of this report is to describe our surgical technique of totally intracorporeal robotic assisted radical cystectomy (RARC) with neobladder formation. Between December 2003 and March 2013, a total of 147 patients (118 male, 29 female) underwent totally intracorporeal RARC for urinary bladder cancer. We also performed a systematic search of Medline, Embase and PubMed databases using the terms RARC, robotic cystectomy, robot-assisted, totally intracorporeal RARC, intracorporeal neobladder, intracorporeal urinary diversion, oncological outcomes, functional outcomes, and complication rates. The mean age of our patients was 64 years (range 37-87). On surgical pathology 47% had pT1 or less disease, 27% had pT2, 16% had pT3 and 10% had pT4. The mean number of lymph nodes removed was 21 (range 0-60). 24% of patients had lymph node positive dAQ1isease. Positive surgical margins occurred in 6 cases (4%). Mean follow-up was 31 months (range 4-115 months). Two patients (1.4%) died within 90 days of their operation. Using Kaplan-Meier analysis, overall survival and cancer specific survival at 60 months was 68% and 69.6%, respectively. 80 patients (54%) received a continent diversion with totally intracorporeal neobladder formation. In the neobladder subgroup median total operating time was 420 minutes (range 265-760). Daytime continence and satisfactory sexual function or potency at 12 months ranged between 70-90% in both men and women. Our experience with totally intracorporeal RARC demonstrates acceptable oncological and functional outcomes that suggest this is a viable alternative to open radical cystectomy.

Full Text Available Objective: To study whether there are factors related to secondary diagnoses (SDg present in patients with prostate cancer that influence the development of urinary incontinence after radical prostatectomy (RP. Materials and methods: A retrospective multicenter observational study was performed reviewing the medical records of 430 men who underwent RP due to organ-confined prostate cancer in 9 different hospitals. Two study groups were distinguished: Group A (GA: Patients without urinary incontinence after RP; Group B (GB: patients with any degree of post-surgical urinary incontinence. Results: Average age at surgery was 63.42 years (range 45-73. 258 patients were continent after surgery and 172 patients complaint of any degree of incontinence after RP. A higher percentage of healthy patients was found in group A (continent after surgery than in group B (p = 0.001. The most common SDg prior to surgery were hypertension, lower urinary tract symptoms, dyslipidemia, diabetes mellitus and erectile dysfunction, but none did show a greater trend towards post-surgical incontinence. Conclusions: A better health status prior to surgery is associated to a lower incidence of new-onset urinary incontinence after radical prostatectomy. However, no correlation was found between the most common medical disorders and the development of post-surgical urinary incontinence.

Urinary incontinence remains a major concern for patients undergoing radical prostatectomy. Its prevalence can reach 20% in the late postoperative period. This clinical study investigated the differences of a dynamic evaluation of the urethra and pelvic floor contraction using perineal ultrasound in men without prostate surgery and in men submitted to radical prostatectomy with and without stress urinary incontinence. Ninety two male patients were included, which 70% of them underwent radical prostatectomy (RP) for more than one year. Thirty one men with clinically post prostatectomy incontinence were compared by two-dimensional (2D) perineal ultrasound to 34 patients without post prostatectomy incontinence and to 27 men without surgery in two centers in Brazil. Our results showed that the continent group presented the urethral angle at rest significantly lower than the prostate group (p = 0.0002). We also observed that the incontinent group showed the displacement of the anterior bladder neck during contraction significantly lower than the continent group (p = 0.008). We found that the continent group presented the urethral angle at rest significantly lower than the prostate group. The incontinent group also showed the anterior bladder neck displacement during contraction significantly lower than the continent group. It was more evident when the severe incontinent group and the continent group were compared.

Radiological management of patients with urinary obstruction following urinary diversion procedures: technical factors, complications, long-term management and outcome. Experience with 378 procedures.

Maher, M M

2012-02-03

We aimed to assess management by interventional radiology techniques of patients with urinary diversion procedures (UD) complicated by urinary obstruction (UO). A 12-year electronic database of interventional cases was searched for urinary access in patients with UD. Patients\\' records were assessed for aetiology of obstruction, indication for procedure, types of interventional radiology, complications and outcome. Management issues included frequency of visits for catheter care, type of catheter placement and technical problems associated with catheter maintenance. Three hundred and seventy eight procedures were carried out in 25 patients (mean age 70 years; Male : Female ratio 13:12). Indications for UD were malignancy (n = 22) and neuropathic bladder (n = 3). UD included ileal conduits (n = 17), cutaneous ureterostomy (n = 3 (2 patients)) and sigmoid colon urinary conduit (n = 6). In most patients, catheters were placed antegradely through nephrostomy tract, but subsequent access was through the UD. Twenty of 25 patients had unilateral stents where as 5 had bilateral stents (8-10- Fr pigtail catheters (20-45 cm in length)). The mean number of procedures including catheter changes was 15 +\\/- 4 per patient and 331 of 378 procedures (87 %) were carried out as outpatients. Since catheter placement, 11 patients required hospital admission on 22 occasions for catheter-related complications. Ureteric strictures in patients with UD can be successfully managed by interventional radiology.

The urethral closure function in continent and stress urinary incontinent women assessed by urethral pressure reflectometry.

Stress urinary incontinence (SUI) occurs when the bladder pressure exceeds the urethral pressure in connection with physical effort or exertion or when sneezing or coughing and depends both on the strength of the urethral closure function and the abdominal pressure to which it is subjected. The urethral closure function in continent women and the dysfunction causing SUI are not known in details. The currently accepted view is based on the concept of a sphincteric unit and a support system. Our incomplete knowledge relates to the complexity of the closure apparatus and to inadequate assessment methods which so far have not provided robust urodynamic diagnostic tools, severity measures, or parameters to assess outcome after intervention. Urethral Pressure Reflectometry (UPR) is a novel method that measures the urethral pressure and cross-sectional area (by use of sound waves) simultaneously. The technique involves insertion of only a small, light and flexible polyurethane bag in the urethra and therefore avoids the common artifacts encountered with conventional methods. The UPR parameters can be obtained at a specific site of the urethra, e.g. the high pressure zone, and during various circumstances, i.e. resting and squeezing. During the study period, we advanced the UPR technique to enable faster measurement (within 7 seconds by the continuous technique) which allowed assessment during increased intra-abdominal pressure induced by physical straining. We investigated the urethral closure function in continent and SUI women during resting and straining by the "fast" UPR technique. Thereby new promising urethral parameters were provided that allowed characterization of the closure function based on the permanent closure forces (primarily generated by the sphincteric unit, measured by the Po-rest) and the adjunctive closure forces (primarily generated by the support system, measured by the abdominal to urethral pressure impact ratio (APIR)). The new parameters enabled

Objectives: Traditionally, the urinary tract has been thought to be sterile in the absence of a clinically identifiable infection. However, recent evidence suggests that the urinary tract harbors a variety of bacterial species, known collectively as the urinary microbiome, even when clinical cultures are negative. Whether these bacteria promote urinary health or contribute to urinary tract disease remains unknown. Emerging evidence indicates that a shift in the urinary microbiome may play an important role in urgency urinary incontinence (UUI). The goal of this prospective pilot study was to determine how the urinary microbiome is different between women with and without UUI. We also sought to identify if characteristics of the urinary microbiome are associated with UUI severity. Methods: We collected urine from clinically well-characterized women with UUI (n = 10) and normal bladder function (n = 10) using a transurethral catheter to avoid bacterial contamination from external tissue. To characterize the resident microbial community, we amplified the bacterial 16S rRNA gene by PCR and performed sequencing using Illumina MiSeq. Sequences were processed using the workflow package QIIME. We identified bacteria that had differential relative abundance between UUI and controls using DESeq2 to fit generalized linear models based on the negative binomial distribution. We also identified relationships between the diversity of the urinary microbiome and severity of UUI symptoms with Pearson's correlation coefficient. Results: We successfully extracted and sequenced bacterial DNA from 95% of the urine samples and identified that there is a polymicrobial community in the female bladder in both healthy controls and women with UUI. We found the relative abundance of 14 bacteria significantly differed between control and UUI samples. Furthermore, we established that an increase in UUI symptom severity is associated with a decrease in microbial diversity in women with UUI

Full Text Available Introduction Urinary incontinence remains a major concern for patients undergoing radical prostatectomy. Its prevalence can reach 20% in the late postoperative period. Materials and Methods This clinical study investigated the differences of a dynamic evaluation of the urethra and pelvic floor contraction using perineal ultrasound in men without prostate surgery and in men submitted to radical prostatectomy with and without stress urinary incontinence. Ninety two male patients were included, which 70% of them underwent radical prostatectomy (RP for more than one year. Thirty one men with clinically post prostatectomy incontinence were compared by two-dimensional (2D perineal ultrasound to 34 patients without post prostatectomy incontinence and to 27 men without surgery in two centers in Brazil. Results Our results showed that the continent group presented the urethral angle at rest significantly lower than the prostate group (p = 0.0002. We also observed that the incontinent group showed the displacement of the anterior bladder neck during contraction significantly lower than the continent group (p = 0.008. Conclusions We found that the continent group presented the urethral angle at rest significantly lower than the prostate group. The incontinent group also showed the anterior bladder neck displacement during contraction significantly lower than the continent group. It was more evident when the severe incontinent group and the continent group were compared.

To evaluate continence and complication rates of bulbar single-cuff (SC) and distal bulbar double-cuff (DC) insertion in male patients with severe stress urinary incontinence (SUI) according to whether the men were considered low or high risk for unfavourable artificial urinary sphincter (AUS) outcomes. In all, 180 male patients who underwent AUS implantation between 2009 and 2013 were followed according to institutional standards. Patients with previous pelvic radiation therapy, open bulbar urethral or UI surgery ('high risk') underwent distal bulbar DC (123 patients) insertion, all others ('low risk') had proximal bulbar SC (57) insertion. Primary and secondary endpoints consisted of continence and complication rates. Kaplan-Meier analysis determined explantation-free survival, and Cox regression models assessed risk factors for persistent UI and explantation. The median follow-up was 24 months. Whereas there was no significant difference in pad usage/objective continence after SC vs DC insertion, superior rates of subjective/social continence and less persistent UI were reported by the patients with DC devices (all P ≤ 0.02). Overall, device explantation (erosion, infection or mechanical failure) occurred in 12.8% of patients. While early ( 0.05), DC patients had a 5.7-fold higher risk of device explantation during late follow-up (P = 0.02) and significantly shorter explantation-free survival (log-rank, P = 0.003). Distal bulbar DC insertion in patients with a 'high-risk' profile (previous pelvic radiation, urethral surgery) leads to similar objective continence, but higher explantation rates when compared with patients considered 'low risk' with proximal bulbar SCs. Randomised controlled trials comparing both devices will be needed to determine whether the higher explanations rates are attributable to the DC device or to underlying risk factors. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.

Full Text Available Background: Prostate cancer is the sixth most common cancer worldwide and will include about 30% of all malignancies in men. Since the initial report of the anatomic radical prostatectomy, refinements in the surgical technique have been made. Several studies show that bladder neck preservation (BNP during radical prostatectomy makes improve early return of urinary continence, erectile function or both. However, some clinical trials have suggested little difference between the return of continence while using modifications. In this study, we compared outcomes of BNP and bladder neck reconstruction (BNR during radical retropubic prostatectomy (RRP. Materials and Methods: This prospective study was performed on 60 patients at a referral university hospital from March 2010 to March 2012. Study population was all patients candidate for RRP (RRP in this period. All patients divided into two groups, A and B (30 patients in each group. Group A (n = 30 who preserved bladder neck (BNP and Group B (n = 30 who had BNR. Prostate specific antigen (PSA before and at 2, 6, 9, 12 and18 months after surgery, anastomotic stricture symptoms, positive bladder neck margin, Gleason score and urine incontinence were compared between two groups. Also, we compared bladder neck contracture, urinary continence and positive surgical margin rates after BNP and BNR while retropubic prostatectomy in 24 months period follow-up. Results: The mean age of the patients was 61.81 ± 7.15 years (range, 50-74 years. After a follow-up period of 24 months, the PSA rising was not different between the two groups. After 2 months, 19 (63.33% of patients in A group and the same number in B group were continent (P = 0.78. Stricture of the bladder neck at the anastomosis site requiring transurethral dilation occurred in 7 (23.33% and 3 (10.0% patients in groups A and B, respectively (P = 0.04. Conclusion: Although there was no difference in prevalence and duration of return of urinary

Full Text Available The diverticula of female urethra are very uncommon, but more frequently found between the third and fifth decade of life. Diverticula area mostly relate to repeated urinary infections of the periurethral glands or urethra’s trauma. The diverticula may cause infection, calculus formation and rarely endometriosis or cancer. A case of a 65-year old Caucasian female with vaginal mass over six months is herein reported. There was no urinary loss, urethral secretion or urinary symptoms.    A cystourethrography showed diverticula with calculus inside. The patient was submitted to surgery and dismissed from the hospital on the first postoperative day. The pathologic examination revealed no malignancy. In six months of follow-up, the patient was continent with no complaints.

The aim of this study was to analyze what kind of urinary symptoms patients have before receiving treatment by radical prostatectomy (RP), and to evaluate their influence on urinary incontinence (UI). Between 2002 and 2012, 758 consecutive patients underwent RP for clinically localized prostate cancer (PCa). Surgery was carried out by open retropubic RP in 545 (73.1%) of patients and laparoscopic RP in 201 (27%) by 5 surgeons who were excluded from data collection and analysis. The following symptoms were collected from the last urological check-ups or pre-operative consultation and classified as: storage symptoms, voiding symptoms, post micturition symptoms, history of acute urinary retention, benign prostatic hyperplasia treatment, history of transurethral resection of the prostate (TURP). A total of 661 patients were included on analysis: 136 (20.6%) patients reported low urinary tract symptoms (LUTS), 162 (24.5%) were considered incontinent after RP, and 45 (33.1%) of them reported LUTS before surgery. Postprostatectomy urinary incontinence (PPUI) was significantly different in patients with LUTS (117 [22.3%] vs. 45 [33.1%], P=0.009). The presence of any LUTS influence significantly in the appearance of PPUI (OR=1.72 [95% CI: 1.14-2.6), P=0.01). TURP is independently influential in PPUI (OR=6.13 [95% CI: 1.86-20.18], P=0.003). A patient with LUTS before surgery has an increased risk of 70% or even 200% to suffer PPUI and a patient who received treatment by TURP is 6 times at higher risk of PPUI. In conclusion, patients with LUTS are likely to present PPUI. History of TURP is influential by itself over PPUI. A good preoperative consultation is important to assess continence status and to create realistic expectations to patients before RP.

Full Text Available AimDefinitive surgery of ectopic ureter in infants is challenging. We propose an endoscopic urinary diversion (EUD as a novel surgical technique in the initial management of symptomatic obstructive ectopic ureter.Patients and methodsSixteen obstructive ectopic ureters (14 patients were initially treated by EUD between 2006 and 2015. All patients had urinary tract dilatation worsening at preoperative US scans and at least two febrile urinary tract infection (UTI or urinary sepsis despite antibiotic prophylaxis. Ectopic ureter was confirmed by cystoscopy. When ectopic meatus was not found, EUD consisted in the creation of a transurethral neo-orifice (TUNO performed by needle puncturing of the ureterovesical wall, under fluoroscopic and ultrasound control. If ectopic meatus was identified in the posterior urethra, “intravesicalization procedure” was done opening the urethral–ureteral wall to create a new ureteral outlet into the bladder.ResultsEUD was done at a median age of 3.5 months (0.5–7 with median follow-up of 48 months (24–136. TUNO was performed in six patients and “intravesicalization” in eight patients. Significant differences were observed in ureteral diameter and anteroposterior pelvis diameter before and after endoscopic treatment (p < 0.005. Initial renal function was preserved in all cases. Postoperative complications were UTI in four patients and TUNO stenosis in one patient, treated by endoscopic balloon dilation. Definitive treatment was further individualized in each patient after 1 year of life.ConclusionEUD is a feasible and safe less-invasive technique in the initial management of symptomatic obstructive ectopic ureter. It allows an adequate ureteral drainage preserving renal function until definitive repair if necessary and does not invalidate other surgical options in case of failure or future definitive treatments.

Although urinary incontinence is prevalent among older women living in rural Korea, a lack of awareness and education exists in this population and among health professionals. Geographic isolation and limited resources also contribute to having few educational offerings for rural nurses. The authors' aim was to develop an online continuing education course on continence care for community health nurses and to examine its effectiveness. A one-group, pretest-posttest design was used to detect changes in knowledge and attitudes after taking the online education course. Participant satisfaction was also measured at the end of the training. A significant improvement in knowledge and attitudes toward continence care was noted. More than 95% of participants responded that they would recommend the online program to other health care providers and indicated the program would be helpful regarding continence care in their practice. The continuing education online course is a feasible strategy to support rural community health nurses' learning to improve knowledge and attitudes toward urinary incontinence management and care.

To review the trends, modifications and results of 103 consecutive total pelvic exenterations (TPE) performed at the Montefiore Medical Center and Albert Einstein College of Medicine from 1987 to 2003. All patients who underwent TPE from January 1987 to December 2003 were included. The medical record, complications, follow-up, clinical status and demographic information were entered in a database. The procedure performed, the method of urinary diversion, colonic diversion, pelvic floor support and vaginal reconstruction were documented. Surviving patients were surveyed regarding their satisfaction with the urinary diversion, the vaginal reconstruction and their sexual function since the surgery. 103 pts were identified. Indications for TPE were recurrent cancers of the cervix (95), endometrium (2), colon and rectum (5), vulva (1). Overall 5-year survival was 47%. 5-year survival for pts with recurrent cervix cancer was 48%. Six pts (6%) recurred >5 years after the TPE. 14 pts (14%) had ureteral anastomotic leaks (no difference between ileal conduit 9/65 (14%) versus 5/38 (13%) continent conduit (P = 0.92). 34 pts (89%) with continent conduits were "continent." 14 pts (17%) had wound complications. 4 pts (4%) had parastomal hernias. 5/11 (46%) pts who had a low rectal reanastomosis developed recurrence in the pelvis. 21/39 (54%) of pts with continent conduits would choose an ileal conduit if they had the option again. Long-term renal function was similar in pts with ileal and continent conduits. Mesh of any type for pelvic floor reconstruction is associated with infection and bowel/urinary fistulas. VRAM flaps for neovagina fill the pelvic dead space, reduce the risk of fistulas and 20/36 pts (55%) are sexually active. Our overall 5-year survival is encouraging, and modifications in surgical technique have improved the reconstructive phase. Low rectal anastomoses at TPE adversely affects survival. Many of our pts with continent urinary diversions would not choose

Full Text Available PURPOSE: To assess the feasibility and performance of radical cystectomy with urinary diversion using exclusively regional anesthesia (i.e. combined spinal thoracic epidural anesthesia, CSTEA. MATERIALS AND METHODS: In 2011 radical cystectomy with extended pelvic and iliac lymphadenectomy was performed on 14 patients using urinary diversion without applying general anesthesia. Under maintained spontaneous breathing, the patients were awake and responsive during the entire procedure. Postoperatively, pain management took three days with the remaining epidural catheter before oral analgesics were administered. Mobilization and diet restoration were carried out according to the fast-track concept. Outcome measurements included operative time, blood loss, beginning of oral nutrition, beginning of mobilization, postoperative pain levels using numerical and visual analog scales (NAS/VAS, length of hospital stay. RESULTS: All surgical procedures were performed without any complications. The absence of general anesthesia did not result in any relevant disadvantages. The postoperative progress was normal in all patients. Particularly, cardiopulmonary complications and enteroparesis did not occur. The provided palliative care proved sufficient (NAS max. 3-4. Discharge followed 10 to 22 days after surgery. At the time of discharge, the patients described the procedure to be relatively positive. CONCLUSIONS: Our data show that CSTEA is an effective technique for radical cystectomy, whereby spontaneous breathing and reduced interference with the cardiopulmonary system potentially lower the perioperative risks especially for high-risk patients. We recommend practice of CSTEA for radical cystectomy to further evaluate and monitor the safety, efficacy, outcomes, and complications of CSTEA.

Full Text Available Background. The purpose of this article is to show a possible method of treatment of postoperative urinary retention after an initial tension-free vaginal tape.Methods. From December 1999 to May 2003 we performed one hundred TVT procedures at our department, among them five women had postoperative urinary retention evaluated with catheterization. Revision and reposition of tension-free vaginal tape were performed if retention of urine was over 100 ml.Results. Urinary retention after an initial tension-free vaginal tape was successfully treated by early reposition of tension-free vaginal tape. This resulted in immediate residualfree voiding and continence, which remained unchanged at 6 week and 3 month follow-up.Conclusions. Postoperative urinary retention may be treated by reposition instead of dissection or elongation of the tension-free vaginal tape.

Involuntary release of urine during sexual climax, orgasm-associated urinary incontinence, occurs frequently after radical prostatectomy. We know little about its prevalence and its effect on sexual satisfaction. To determine the prevalence of orgasm-associated incontinence after radical prostatectomy and its effect on sexual satisfaction. Consecutive series, follow-up at one point in calendar time of men having undergone radical prostatectomy (open surgery or robot-assisted laparoscopic surgery) at Karolinska University Hospital, Stockholm, Sweden, 2002-2006. Of the 1,411 eligible men, 1,288 (91%) men completed a study-specific questionnaire. Prevalence rate of orgasm-associated incontinence. Of the 1,288 men providing information, 691 were sexually active. Altogether, 268 men reported orgasm-associated urinary incontinence, of whom 230 (86%) were otherwise continent. When comparing them with the 422 not reporting the symptom but being sexually active, we found a prevalence ratio (with 95% confidence interval) of 1.5 (1.2-1.8) for not being able to satisfy the partner, 2.1 (1.1-3.5) for avoiding sexual activity because of fear of failing, 1.5 (1.1-2.1) for low orgasmic satisfaction, and 1.4 (1.2-1.7) for having sexual intercourse infrequently. Prevalence ratios increase in prostate-cancer survivors with a higher frequency of orgasm-associated urinary incontinence. We found orgasm-associated urinary incontinence to occur among a fifth of prostate cancer survivors having undergone radical prostatectomy, most of whom are continent when not engaged in sexual activity. The symptom was associated with several aspects of sexual life. © 2011 International Society for Sexual Medicine.

[Established treatment options for male stress urinary incontinence].

Nowadays, male stress urinary incontinence is rare and almost always of iatrogenic origin (radiotherapy, pelvic surgery). However, the prognosis of urinary incontinence following surgery is good and can be improved by pelvic floor muscle exercises in combination with biofeedback systems. For the remaining patient cohort with persistent urinary incontinence, several established surgical treatment options are available. Suburothelial injections of bulking agents can easily be performed in an ambulatory setting. However, regardless of the material used, long-term results are disappointing. Moreover, the residual urethral function deteriorates due to cicatrization of the suburothelial plexus with consequent loss of urethral elasticity. The fascial sling procedure in males has to be performed in preoperated areas and is as technically demanding for the surgeon as it is burdening for the patient. Alloplastic material is not used, thus minimizing risks for arrosion or infection. Since the sling tension can neither be standardized nor postoperatively readjusted, the risk of overcorrection is considerable and the success of the procedure is heavily dependent on the surgeon's experience. Despite wear and high revision rates, the technically mature artificial sphincter produces excellent continence results and has become the gold standard in the therapy of male stress urinary incontinence. The circumferential and continuous urethral compression by the cuff is highly effective, but at the price of an almost inevitable urethral atrophy. To overcome this problem, various surgical techniques have been developed (tandem cuff, cuff downsizing, transcorporal cuff placement). However, the expensive artificial sphincter is not a nostrum for every incontinent man, since it requires certain minimal cognitive and manual capabilities. Therefore, the search for less demanding treatment alternatives seems to be necessary, even if one has to accept lower continence rates.

Full Text Available OBJECTIVE: To assess the effect of a weekly, short-term physical therapy intervention on the pelvic floor muscles and urinary incontinence (UI among patients of the public health system. METHOD: Quasi-experimental before-and-after study. Clinical history and function evaluation were performed using perineal bidigital maneuvers and perineometry. The intervention consisted of transvaginal electrical stimulation and pelvic floor kinesiotherapy. Data were analyzed using the paired t test or Wilcoxon signed-rank test, Pearson product-moment correlation coefficient or Spearman's rank correlation coefficient. A value of P<0.05 was considered significant. RESULTS: Eight-two women 55.1±10.9 years-old were evaluated. Mixed urinary incontinence (MUI, stress urinary incontinence (SUI and urge urinary incontinence (UUI were observed in 52.4%, 36.6% and 11%, respectively. The length of UI was 6.0 years (3.0-10. Approximately 13.64 physical therapy sessions were held on average. There was no difference in perineometry measurements following the intervention (40.6±24.1 versus 41.7±25.4, P=0.098. Muscle function significantly increased (P<0.01 in the bidigital maneuver. The patients reported being continent or satisfied with the treatment in 88.9% of cases. CONCLUSIONS: The results demonstrated an increase in muscle function and the attainment of urinary continence or treatment satisfaction in most cases.

Artificial urinary conduit construction using tissue engineering methods.

Kloskowski, Tomasz; Pokrywczyńska, Marta; Drewa, Tomasz

2015-01-01

Incontinent urinary diversion using an ileal conduit is the most popular method used by urologists after bladder cystectomy resulting from muscle invasive bladder cancer. The use of gastrointestinal tissue is related to a series of complications with the necessity of surgical procedure extension which increases the time of surgery. Regenerative medicine together with tissue engineering techniques gives hope for artificial urinary conduit construction de novo without affecting the ileum. In this review we analyzed history of urinary diversion together with current attempts in urinary conduit construction using tissue engineering methods. Based on literature and our own experience we presented future perspectives related to the artificial urinary conduit construction. A small number of papers in the field of tissue engineered urinary conduit construction indicates that this topic requires more attention. Three main factors can be distinguished to resolve this topic: proper scaffold construction along with proper regeneration of both the urothelium and smooth muscle layers. Artificial urinary conduit has a great chance to become the first commercially available product in urology constructed by regenerative medicine methods.

We present our management of lower urinary tract (LUT) mesh perforation after mid-urethral polypropylene mesh sling using a novel combination of surgical techniques including total or near total mesh excision, urinary tract reconstruction, and concomitant pubovaginal sling with autologous rectus fascia in a single operation. We retrospectively reviewed the medical records of 189 patients undergoing transvaginal removal of polypropylene mesh from the lower urinary tract or vagina. The focus of this study is 21 patients with LUT mesh perforation after mid-urethral polypropylene mesh sling. We excluded patients with LUT mesh perforation from prolapse kits (n = 4) or sutures (n = 11), or mesh that was removed because of isolated vaginal wall exposure without concomitant LUT perforation (n = 164). Twenty-one patients underwent surgical removal of mesh through a transvaginal approach or combined transvaginal/abdominal approaches. The location of the perforation was the urethra in 14 and the bladder in 7. The mean follow-up was 22 months. There were no major intraoperative complications. All patients had complete resolution of the mesh complication and the primary symptom. Of the patients with urethral perforation, continence was achieved in 10 out of 14 (71.5 %). Of the patients with bladder perforation, continence was achieved in all 7. Total or near total removal of lower urinary tract (LUT) mesh perforation after mid-urethral polypropylene mesh sling can completely resolve LUT mesh perforation in a single operation. A concomitant pubovaginal sling can be safely performed in efforts to treat existing SUI or avoid future surgery for SUI.

We evaluated the performance of prototype underwear designed to detect urine leakage from continence pads, their acceptability to users, and their effect on health-related quality of life and psychosocial factors. Prototype product evaluation. Participants were 81 women with an average age of 67 years (range, 32-98 years) recruited between October 2010 and February 2012 from outpatient clinics, general practice surgeries, community continence services, and through charities and networks. The TACT3 project developed and manufactured a prototype undergarment designed to alert the wearer to a pad leak before it reaches outer clothing or furniture. The study was conducted in 2 stages: a pilot/feasibility study to assess general performance and a larger study to measure performance, acceptability to users, health-related quality of life, and psychosocial impact. Participants were asked to wear the prototype underwear for a period of 2 weeks, keeping a daily diary of leakage events for the first 7 days. They also completed validated instruments measuring lower urinary tract symptoms, health-related quality of life, and psychosocial impact. On average, 86% of the time participants were alerted to pad leakage events. More than 90% thought the prototype underwear was "good" or "OK" and that it would or could give them more confidence. Mean scores for the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form indicated no change in the level of symptoms reported before or after the intervention, and no significant changes in health-related quality of life status occurred, except improvement in for travel restrictions. Evaluation via the Psychosocial Impact of Assistive Devices Scale also indicated a positive impact. The prototype underwear evaluated in this study was effective and acceptable for 5 out of every 10 wearers. Findings also suggest that the prototype underwear is suitable for women of all ages, dress sizes, and continence

Objective: To determine the medium and long-term outcome of orthotopic continent urinary diversion with ileal (Studer) neo-bladder following radical cystectomy. Study Design: Case series. Place and Duration of Study: Department of Surgery, The Aga Khan University Hospital, Karachi, from January 1998 to September 2010. Methodology: Thirty eight patients underwent radical cystectomy for invasive bladder tumor with ileal neo-bladder (Studer type) reconstruction. Peri-operative and late complications, functional outcome of neo-bladder, urinary continence, metabolic and upper urinary tract status and overall survival were evaluated in all patients. Results: A total of 29 patients (23 males and 6 females) with mean age of 59 +- 12 years were included for the final analysis. The mean duration of surgery (both radical cystectomy and urinary diversion) was 520 +- 70 minutes. Perioperative complication rate was 24% (n=7) with surgical site infection in 4 patients, sepsis in 1 patient and 2 had ureteroileal leak. At 6 months follow-up, 22 patients were fully continent while 7 patients had minimal stress / nocturnal incontinence. The continence rate was 93% (n=27) at one year follow-up. The mean capacity of neo-bladder at 6 months was 384 +- 66 mLs. The late complication rate was 17% (n=5). Three patients developed anastomotic stricture requiring transurethral incision of neo bladder neck, one formed stone in neo-bladder and one developed incision hernia. All patients had preserved renal functions on follow-up. The survival rate was 80% (n=23) at a median follow-up of 66.4 +- 36 months. Two patients developed local recurrence and four developed distant metastasis. Conclusion: Studer ileal neo-bladder is a safe and effective option for urinary diversion in select patients with good oncological and functional outcomes comparable to contemporary literature, even in a low volume center.

To compare pelvic floor muscles (PFMs) performance in women with and without stress urinary incontinence (SUI) during endurance test. It is a prospective case-control clinical trial. After determining PFM maximal voluntary contraction (MVC) by electromyography (EMG), women underwent endurance test, which consisted of consecutively PFM 1-sec fast contractions reaching MVC amplitude followed by 1-sec rest. Training time guided by Borg perceived exertion scale was noted. Heart rate (HR) behavior and EMG variables were assessed before and after training making a physiological analysis in both groups. A total of 56 women, mean age 52.19 years old, were evaluated (26 continent and 30 incontinent women). The time that SUI and continent women took to reach fatigue (Borg 10) was 9.1 ± 4.7 and 14.19 ± 8.32 min, respectively (P = 0.006). Confirming that all women performed similar effort during the test, analysis of variance with repeated measures showed that during the endurance test both groups presented similar increase in HR, showing detectable and significant increase from resting time to Borg 10 (P continent and SUI women, with a decrease from the baseline resting amplitude (P = 0.003 for SUI women and P = 0.006 for continent women). Women with SUI showed worse performance during an endurance test than continent women. It suggests that women have different capacity to perform PFM training. An initial evaluation based on PFM performance would help to define the best individualized PFM training. © 2014 Wiley Periodicals, Inc.

Full Text Available OBJECTIVE: We developed an experimental ex-vivo model to define factors that may influence continence of catheterizable channels by urinary and colonic stomas based on the principle of imbrication of the outlet tube. MATERIALS AND METHODS: From 20 pigs, colon specimens with 25 cm length were obtained and a transverse flap with 3.0 cm length x 1.5 cm width in the average point of the intestine was tubulated to create an efferent tube. With the tube configured, it was embedded by 3 seromuscular stitches far 0.5 cm each other. A pressure study of both intra-luminal surface and channel was then conducted during the filling of the submerse piece with environmental air in a water container, to define the efferent channel continence. The study was repeated after the progressive release of suture stitches until only one stitch remains. RESULTS: Channel continence analyzed in each segment in three different valve length situations, making a total of 20 segments, revealed that with 3 stitches (1.5 cm valve the maximum average pressure prior to overflow was 54 cm H2O; 53.65 cm H2O with 2 stitches (1.0 cm of valve, and 55.45 cm H2O with only one stitch (0.5 cm of valve, which are the same values. The record at the segment explosion pressure was 67.87 cm H2O. CONCLUSION: The study showed that angulation of channel with colon, maintained by only one stitch (0.5 cm imbrication was more important than a larger extension of the valve, represented by 3 suture stitches (1.5 cm imbrication in order to allow continence to the efferent channel.

Young African Scientists Session at the Fourth International Geosphere-Biosphere Programme Congress; Cape Town, South Africa, 7 May 2008; Africa is often described as a unique and diverse continent. This is reflected in its biodiversity, economic and social circumstances, and diversity in culture and environment. The Young African Scientists (YAS) session at the International Geosphere-Biosphere Programme Congress was one of the congress's highlights. Global environmental change research in Africa was presented to an audience that included visiting international and national scientists, policy makers, and a group of schoolchildren. From the uniqueness of Africa's paleoclimate to the diversity and complexity of current and future impacts of environmental change on Africa, the session not only provided an overview of current projects but also highlighted the problems that are intertwined with poverty. This session was sponsored by the Global Change System for Analysis, Research, and Training (START).

This qualitative study summarizes information that individuals shared online about use of OxyContin following the August 2010 introduction of the abuse deterrent formulation (ADF). The primary objective was to study online posts that endorsed continued use of OxyContin or a switch from OxyContin to another formulation of oxycodone or another substance altogether following the introduction of the ADF. A secondary objective was to determine whether posts revealed that the ADF led to cessation of OxyContin use. Data were collected with the Researched Abuse, Diversion, and Addiction-Related Surveillance System Web Monitoring Program, an online surveillance system that collects and organizes posts about prescription drugs from social media websites, blogs, and forums from 3Q2009 to 4Q2014 using a commercially available web platform. Posts were categorized by whether they conveyed a switch to drugs other than reformulated OxyContin or a continuation of reformulated OxyContin abuse. "Switch posts" primarily discussed switching to immediate-release opioids. "Continue abusing" posts identified tampering strategies for alternate routes of administration, oral use, and continued use although post authors were generally unhappy with the experience. No reference to OxyContin cessation as a function of the introduction of the ADF was found; however, discontinued use was discussed. Web Monitoring data are useful for capturing cross sections of Internet conversation reflecting reactions to new drug formulations. These data support the notion that users will gravitate to non-ADFs generally, and to immediate-release non-ADF opioid formulations, specifically, as long as these options remain on the market.

To assess prevalence and severity of lower urinary tract function in 85-year-old men and women. Little is known on the prevalence of lower urinary tract dysfunction in this geriatric age group, which is now the fastest growing sector of the population worldwide. The Vienna Trans-Danube Aging study (VITA) is a longitudinal, population-based study initiated in 2000 that included men/women aged 75 years living in a well-defined area in Vienna. The main purpose of the VITA study was to identify risk factors for incident Alzheimer's disease. All study participants alive in 2010 were contacted by mail to complete a detailed questionnaire on various aspects of lower urinary tract symptoms (LUTS) and urinary incontinence (UI). The response rate was 68%, resulting in a total of 262 questionnaires available for analysis (men n= 96; women n= 166). All study participants were 85 years of age. Urinary incontinence defined as any involuntary loss during the past 4 weeks was reported by 24% of men and 35% of women (P= 0.04). Stress UI was more frequent in women (39%) than in men (14%, P 0.05). Nocturia more often than twice was more prevalent in men (69%) than in women (49%) (P= 0.02). Overactive bladder, according to International Continence Society criteria, was present in 55% of women and 50% of men. No difference regarding quality of life impairment as the result of LUTS and UI was noticed between sexes. A few co-morbidities were identified to correlate with UI and storage symptoms. These data provide insights into the prevalence and severity of LUTS and UI in individuals in their eighties, to our knowledge the largest population-based study in this age group. Demographic changes in upcoming decades underline the importance of a thorough understanding of lower urinary tract dysfunction in a geriatric population. © 2012 BJU INTERNATIONAL.

Full Text Available Purpose To evaluate preoperative rectal electrical stimulation in the recovery of urinary continence in patients who undergo radical retropubic prostatectomy. Materials and Methods Patients were divided into 3 randomized groups: control, pelvic exercises, and electrical stimulation. A 1 hour pad-test, the ICIQ-SF, and the SF-36 were performed 1, 3, and 6 months after the surgical procedure. Results Of the 58 patients who were initially included in the study, 9 were excluded due to radiotherapy after surgical intervention, an indwelling urethral catheter for more than 30 days, high surgical risk, loss of follow-up, or incomplete participation in the study routines and spontaneous interruption. Forty-nine patients concluded the study (15 in the control group, 17 in the exercise group, and 17 in the electrical stimulation group. We did not observe any significant difference in the pad test (p > 0.05, the 8 domains of the SF-36, or ICIQ-SF score compared with control groups (control, exercise, and electrical stimulation. Conclusion Preoperative rectal electrical stimulation has no impact on continence status in patients who undergo radical retropubic prostatectomy. There is no difference in the three above mentioned groups with regard to urinary leakage and quality of life.

While many women report urinary incontinence (UI) during pregnancy, associations with pre-pregnancy urinary leakage remain under-explained. We performed a multi-strand prospective cohort study with 860 nulliparous women recruited during pregnancy. Prevalence of any urinary leakage was 34.8% before and 38.7% during pregnancy. Prevalence of UI, leaking urine at least once per month, was 7.2% and 17.7% respectively. Mixed urinary incontinence (MUI) was reported by 59.7% of women before and 58.8% during pregnancy, stress urinary incontinence (SUI) by 22.6% and 37.2%, and urge urinary incontinence (UUI) by 17.7% and 4.0%, respectively. SUI accounted for half (50.0%), MUI for less than half (44.2%), and UUI for 5.8% of new-onset UI in pregnancy. Pre-pregnancy UI was significantly associated with childhood enuresis [adjusted odds ratio (AOR) 2.9, 95% confidence interval (CI) 1.5-5.6, p = 0.001) and a body mass index (BMI) ≥30 kg/m 2 (AOR 4.2, 95% CI 1.9-9.4, p pregnancy BMI was 25-29.99 kg/m 2 (AOR 2.0, 95% CI 1.2-3.5, p = 0.01), and women who leaked urine less than once per month (AOR 2.6, 95% CI 1.6-4.1, p  pregnancy. Considerable proportions of nulliparous women leak urine before and during pregnancy, and most ignore symptoms. Healthcare professionals have several opportunities for promoting continence in all pregnant women, particularly in women with identifiable risk factors. If enquiry about UI, and offering advice on effective preventative and curative treatments, became routine in clinical practice, it is likely that some of these women could become or stay continent.

Full Text Available Purpose: To evaluate the effects of phosphodiesterase type 5 inhibitor (PDE5i on urinary continence recovery after bilateral nerve-sparing radical prostatectomy (BNSRP. Materials and Methods: Between 2002 and 2012, 137 of 154 consecutive patients who underwent BNSRP in our institution retrospectively divided into 3 groups that included patients taking PDE5i immediately after surgery (immediate PDE5i group, n=41, patients starting PDE5i at an outpatient clinic after discharge (PDE5i group, n=56, and patients taking no medication (non-PDE5i group, n=40. Using self-administered questionnaires, the proportion of patients who did not require incontinence pads (pad-free patients was calculated preoperatively and at 1, 3, 6, 12, 18, and 24 months after BNSRP. Severity of incontinence was determined based on the pad numbers and then compared among the 3 groups. Results: Proportions of pad-free patients and severity of incontinence initially deteriorated in all of the groups to the lowest values soon after undergoing BNSRP, with gradual improvement noted thereafter. The deterioration was most prominent in the immediate PDE5i group. As compared to the non-PDE5i group, both the PDE5i and immediate PDE5i groups exhibited a better final continence status. Conclusions: PDE5i improves final continence status. However, administration of PDE5i immediately after surgery causes a distinct temporary deterioration in urinary incontinence.

To estimate the prevalence of lower urinary tract symptoms, urinary incontinence and overactive bladder in western Turkey. This cross-sectional, population-based survey was carried out between May and October 2012. A random sample of 2128 women and men aged ≥18 years was selected from the health registries. A questionnaire including sociodemographic data, comorbid conditions, lower urinary tract symptoms, overactive bladder and urinary incontinence symptoms, body mass index, vital signs, and dipstick urinalysis was developed. The questions were answered by the participants, and remaining data were provided by the site staff. International Continence Society definitions were used. A total of 1571 (74%) individuals agreed to participate, and analysis were carried out on 1555 people (636 men [40.9%] and 919 women [59.1%]) after 16 individuals with a nitrite-positive dipstick test were excluded. Lower urinary tract symptoms were reported by 71.0% of the study population. The prevalence of storage, voiding and post-micturition symptoms were 56.1% (44.2% men, 64.1% women), 39.3% (40.9% men, 37.8% women) and 30.7% (38.6% men, 28.7% women), respectively. The most prevalent storage symptom was urgency, which was reported by 29.3% of the study population (20.1% men, 35.6% women). The prevalence of urge, stress and mixed urinary incontinence were: 6.5% (3.9% men, 8.2% women), 14.1% (3.9% men, 21.2% women) and 5.6% (0.8% men, 9.0% women), respectively. The present study is the first and largest population-based survey evaluating the prevalence of lower urinary tract symptoms, urinary incontinence and overactive bladder in Turkey. Our findings show these symptoms are highly prevalent in western Turkey. © 2014 The Japanese Urological Association.

Full Text Available Aim: To compare the continence results and complications of the tension-free vaginal tape (TVT and transobturator tape (TOT procedures. Material and Method: Sixty two urinary incontinence patients; (37 were stress urinary incontinence and 25 were mixed incontinence underwent TVT or TOT. The clinic-pathologic parameters of the patients, perioperative and postoperative complications and outcome in terms of continence and quality of life were compared. Results: TOT and TVT were performed on % 50 of the patients respectively. An objective cure rate in patients who underwent TOT was observed in 74% of cases, an objective improvement in 26% of cases. 11 of the patients had dysuria, 10 of them had suprapubic pain. An objective cure rate in patients who underwent TVT was observed in 90% of cases, an objective improvement in 8% of cases. A de novo urge incontinence presented in 2 patients. The quality of life improved in 93,5% of cases. In terms of continence results and quality of life, there was no significant difference between the procedures. The complication rate was higher with the TVT procedure when compared to that of the TOT procedure. Discussion: TOT procedure in short terms, performs similar operational success with the TVT procedure. Operational time; in consideration of the cystoscopy time, can be an advantage compared to the TVT procedure. If the operation includes anterior colporrhaphy, the success of both procedures reduces.

2018-02-01

X-ray photon correlation spectroscopy (XPCS) and dynamic light scattering (DLS) both reveal dynamics using coherent scattering, but X-rays permit investigating of dynamics in a much more diverse array of materials. Heterogeneous dynamics occur in many such materials, and we showed how classic tools employed in analysis of heterogeneous DLS dynamics extend to XPCS, revealing additional information that conventional Kohlrausch exponential fitting obscures. This work presents the software implementation of inverse transform analysis of XPCS data called CONTIN XPCS, an extension of traditional CONTIN that accommodates dynamics encountered in equilibrium XPCS measurements.

Assess the impact of subsequent urinary incontinence risk factors in women with different urinary incontinence history. In a cohort study 232 women answered validated questions about urinary incontinence after the first delivery and 12 years later. Women who were continent during the first pregnancy or postpartum period (group 1) or who became incontinent during these periods (group 2) were identified. Urinary incontinence symptoms 12 years after the first delivery were reported by 32.6% (44/135) in group 1 and 66.0% (64/97) in group 2. Overweight and to a minor extent pelvic organ prolapse symptoms or heavy lifting at work was associated with higher relative risk of urinary incontinence in group 1 compared with group 2. Other risk factors such as age, breastfeeding 6 months or longer after both the first and second deliveries, bowel movements or urinary infections were not associated differentially with urinary incontinence in the 2 groups. Subsequent risk factors had a more significant impact in women without initial urinary incontinence.

TVT-Secur mini-sling for stress urinary incontinence: a review of outcomes at 12 months.

• Synthetic mid-urethral slings (MUSs) are considered the first choice surgical procedure for stress urinary incontinence. Recent publications have raised concerns about the efficacy of third generation single-incision mini-slings. The present paper is a systematic review of studies reporting 12-month outcomes after the TVT-Secur (TVT-S) procedure. • Pubmed/Medline online databases, abstracts from recent International Continence Society and International Urogynecological Association annual scientific meetings and the Clinicaltrials.gov and Controlled-trials.com online trial registries were searched for English-language articles containing the terms 'TVT-Secur', 'TVT Secur' or 'mini-sling'. The primary outcomes were objective and subjective cure rates at 12 months. Secondary outcomes included peri-operative (vaginal perforation, urinary retention, urinary tract infection [UTI]) and postoperative (mesh exposure, de novo overactive bladder (OAB), dyspareunia and return to theatre) complication rates. • Among 1178 women undergoing the TVT-S procedure, from 10 studies, both objective and subjective cure rate at 12 months was 76%, with objective cure significantly higher in women undergoing the 'U-type' approach. Vaginal perforation was a complication in 1.5% of cases, with a 2.4% incidence of mesh exposure in the first year. The incidence of de novo OAB symptoms was 10%. Rates of urinary retention (2.3%), UTI (4.4%), dyspareunia (1%) and return to theatre for complications (0.8%) were low. In the first year after a TVT-S procedure 5% of women required repeat continence surgery. • Longer-term studies and randomized comparisons with more established MUSs are required before TVT-S should be routinely used in the surgical treatment of stress urinary incontinence. © 2011 THE AUTHOR.

To assess the effect of a weekly, short-term physical therapy intervention on the pelvic floor muscles and urinary incontinence (UI) among patients of the public health system. Quasi-experimental before-and-after study. Clinical history and function evaluation were performed using perineal bidigital maneuvers and perineometry. The intervention consisted of transvaginal electrical stimulation and pelvic floor kinesiotherapy. Data were analyzed using the paired t test or Wilcoxon signed-rank test, Pearson product-moment correlation coefficient or Spearman's rank correlation coefficient. A value of Pphysical therapy sessions were held on average. There was no difference in perineometry measurements following the intervention (40.6±24.1 versus 41.7±25.4, P=0.098). Muscle function significantly increased (P<0.01) in the bidigital maneuver. The patients reported being continent or satisfied with the treatment in 88.9% of cases. The results demonstrated an increase in muscle function and the attainment of urinary continence or treatment satisfaction in most cases.

Evolving Continents

Hamilton, Warren

Brian Windley succeeds very well indeed at the formidable task he sets for himself in this greatly revised second edition of a book that first appeared in 1977. He synthesizes primarily the tectonic and petrologic evolution of the continents and secondarily their economic geologic, stratigraphic, and biologic history. The book is organized in well-balanced time sequence and topical chapters, followed by a fine overview. The author describes examples, generalizes from them, and seeks understanding of variations with time and with depth of the process acting on continents within a plate tectonic framework.

Women undergoing radical cystectomy (RC) and urinary diversion for bladder cancer experience substantial limitations in health-related quality of life (HRQOL). However, the level of discomfort caused by different urinary diversion has been never evaluated in long term survivors. The aim of this multicenter study is to evaluate differences in HRQOL among recurrence-free women undergoing cutaneous ureterostomy (CUS), Bricker's ileal conduit (BK-IC) and Orthotopic neobladder VIP (ONB-VIP) in disease-free females treated with radical cystectomy (RC), with long-term follow up (mean 60.1 months; range 36-122 months). All consecutively treated female patients from two urological institutions who underwent RC and urinary diversion from January 2000 to December 2008, with no evidence of tumor recurrence at a minimum follow up of 36 months, were included. Patients received the European Organisation for Research and Treatment of Cancer (EORTC) generic (QLQ-C30) and bladder cancer-specific instruments (QLQ-BLM30) and the Functional Assessment of Cancer Therapy for Bladder Cancer (FACT-BL). Clinical data and questionnaire results were analyzed in order to evaluate the HRQOL differences among diversion groups. We identified 37 females (median age: 68, range 45-82 years), including 12 status-post CUS, 16 who underwent BK-IC, and 9 who underwent ONB-VIP. Most were healthy (24/37 with no comorbidities, 4/37 Charlson 1-2, 9/37 Charlson 3 or greater - we didn't considered bladder cancer in Charlson evaluation because bladder cancer was the main inclusion criteria). Women undergoing CUS endorsed worse FACT-BL scores compared with BK-IC and ONB-VIP patients, worse HRQOL regarding physical and emotional well-being (p=0.008 and p=0.02, respectively), and a trend toward worse EORTC QLQ-C30 scores for appetite loss and fatigue (p=0.05 for both). In our study long-term disease-free females treated with CUS endorsed worse HRQOL compared with women who underwent BK-IC or ONB-VIP, mostly due

The pathophysiological mechanism of incontinence is multifactorial. We evaluated the role of 3D-4D ultrasound in the assessment of the fascial supports of the urethra and the urethral sphincter complex (USC) for diagnosing stress urinary incontinence. Observational case-control study in women with and without stress urinary incontinence attending a urogynecology service and a general gynecology service. All women were interviewed, examined, and classified according to the Pelvic Organ Prolapse Quantification (POP-Q) and underwent a 3D-4D translabial ultrasound. Fascial supports of the urethra were assessed by tomographic ultrasound and were considered to be intact or absent if it was possible to identify them at eight levels on each side, urethral mobility was assessed on maximal Valsalva in sagittal section and the length and volume of the USC at rest and on maximal Valsalva were determined using the Virtual Organ Computer-aided Analysis (VOCAL) program. Variables were compared between continent and incontinent women. A total of 173 women were examined, 78 continent and 95 incontinent. There was a significant difference in urethral mobility between continent and incontinent women (12.82 mm vs. 21.85 mm, P rest was significantly shorter (P continent and incontinent women. However, the length of the USC at rest was shorter and urethral mobility was higher in incontinent women. Neurourol.

Retrospective analysis of a series of patients with stress urinary incontinence that underwent surgery in our department, by means of the TVT and TOT techniques. We evaluate post operative continence, considering "cured" the patient with complete continence and "failure" any type of involuntary stress urine leak, independently of its severity registering the time of its appearance. For this purpose we used the Kaplan-Meier analysis comparing both techniques with the Breslow test. Additionally, postoperative complications were evaluated. 128 patients who underwent surgery by TVT (69 patients, 53.9%) and TOT (59 patients, 46.1%). Mean age was 54.4 years for TVT (95% CI 52.0-56.8) and 59 years for TOT (95% CI 55.9-62.1). Mean follow-up time was 18.7 months for TVT (95% CI 15.6-21.9) and 7.4 months for TOT (95% CI 5.8-8.9). Overall continence rate was 86.7%, 88.4% for TVT and 84.7% for TOT The probability of being continent six months after surgery was 89.1% for TVT and 78.2% for TOT (no significant differences, p = 0.31), with almost all failures within the first six months after surgery. TVT was more frecuently associated with urgency symptoms (33.3%, p = 0.001) and urge incontinence (18.8%,p = 0.16), urinary retention (11.6%, p = 0.38), and prevesical hematoma requiring mesh retrieval. Greater post operative pain was observed with TOT (20.3%, p = 0.005). Our results evidence a similar efficacy with both techniques, with the failures appearing over the first months after surgery. Complications of the voiding urgency type are significantly more frequent with TVT.

Objectives Female stress urinary incontinence (SUI) is caused by urethral dysfunction during dynamic conditions, but current technology has limitations in measuring urethral pressures under dynamic conditions. An 8-French high resolution manometry catheter (HRM) currently in clinical use in gastroenterology may accurately measure urethral pressures under dynamic conditions because it has a 25ms response rate and circumferential pressure sensors along the length of the catheter (ManoScan® ESO, Given Imaging). We evaluated the concordance, repeatability, and tolerability of this catheter. Methods We measured resting, cough, and strain maximum urethral closure pressures (MUCPs) using HRM and measured resting MUCPs with water perfusion side-hole catheter urethral pressure profilometry (UPP) in 37 continent and 28 stress incontinent subjects. Maneuvers were repeated after moving the HRM catheter along the urethral length to evaluate whether results depend on catheter positioning. Visual analog pain scores evaluated the comfort of HRM compared to UPP. Results The correlation coefficient for resting MUCPs measured by HRM vs. UPP was high (r = 0.79, prest, cough, and strain with HRM: r= 0.92, 0.89, and 0.89. Mean MUCPs (rest, cough, strain) were higher in continent than incontinent subjects (all p continent subjects during cough and strain maneuvers compared to rest. Conclusions This preliminary study shows that HRM is concordant with standard technology, repeatable, and well tolerated in the urethra. Incontinent women have more impairment of their urethral closure pressures during cough and strain than continent women. PMID:25185595

Female stress urinary incontinence is caused by urethral dysfunction during dynamic conditions, but current technology has limitations in measuring urethral pressures under these conditions. An 8-French high-resolution manometry (HRM) catheter currently in clinical use in gastroenterology may accurately measure urethral pressures under dynamic conditions because it has a 25-millisecond response rate and circumferential pressure sensors along the length of the catheter (ManoScan ESO; Given Imaging, Yoqneam, Israel). We evaluated the concordance, repeatability, and tolerability of this catheter. We measured resting, cough, and strain maximum urethral closure pressures (MUCPs) using HRM and measured resting MUCPs with water-perfusion side-hole catheter urethral pressure profilometry (UPP) in 37 continent and 28 stress-incontinent subjects.

Mean MUCPs (rest, cough, and strain) were higher in continent than in incontinent subjects (all P continent subjects during cough and strain maneuvers compared to rest. This preliminary study shows that HRM is concordant with standard technology, repeatable, and well tolerated in the urethra. Incontinent women have more impairment of their urethral closure pressures during cough and strain than continent women.

To examine the impact of tamsulosin on the rate of acute urinary retention following early catheter removal after robot-assisted laparoscopic radical prostatectomy. A total of 236 patients who underwent robot-assisted laparoscopic radical prostatectomy for prostate cancer carried out by a single surgeon were enrolled in this randomized study. Patients were randomly divided into two groups: treatment with tamsulosin (0.4 mg) from 1 day before to 14 days after surgery (tamsulosin group), or no tamsulosin treatment (control group). The urethral catheter was removed on the fifth postoperative day. The primary end-point was the acute urinary retention rate. Changes in each domain of the International Continence Society male short-form questionnaire and uroflowmetry parameters were secondary end-points. The primary end-point was assessed in 218 patients (92.4%; n = 109 in each group). It was not assessed in 18 patients because of cystographic leak from the vesicourethral anastomosis. The acute urinary retention rate was lower in the tamsulosin group (7.3%) than in the control group (17.4%, P = 0.018). Multivariate logistic regression analysis identified tamsulosin treatment and the operative experience of the surgeon as independent risk factors for acute urinary retention. Tamsulosin-treated patients had a 0.30-fold lower risk of developing acute urinary retention compared with control patients (95% confidence interval 0.12-0.76; P = 0.011). None of the International Continence Society male questionnaire domain scores showed significant changes between the groups. Perioperative treatment with tamsulosin in patients undergoing robot-assisted laparoscopic radical prostatectomy reduces the rate of acute urinary retention after early catheter removal, without aggravating urinary incontinence. © 2013 The Japanese Urological Association.

To test the impact of surgeon experience on urinary continence (UC) recovery after robot-assisted radical prostatectomy (RARP). The study included 1477 consecutive patients treated with RARP by four surgeons between 2006 and 2014. UC recovery was defined as being completely dry over a 24-hour period at follow-up. Surgeon experience was coded as the total number of RARP performed by the surgeon before the patient's operation. Multivariable analysis tested the association between surgeon experience and UC recovery. Covariates consisted of patient age, Charlson comorbidity index, preoperative International Index of Erectile Function-Erectile Function domain (IIEF-EF), nerve-sparing surgery (none vs unilateral vs bilateral), and preoperative risk groups (low- vs intermediate- vs high risk). The number of cases performed by each surgeon was 541, 413, 411, and 112, respectively. Median follow-up was 24 months (inter-quartile range: 18, 40). The UC recovery rate at 1 year after surgery was 82%. At multivariable analyses, surgeon experience represented an independent predictor of UC recovery (hazard ratio: 1.02, p < 0.001). The surgical learning curve was similar among surgeons, moving linearly from ∼60% of UC rate at the initial cases to almost 90% after more than 400 procedures. In patients undergoing RARP, surgeon experience is a significant predictor of UC recovery. The surgical learning curve of UC recovery does not reach a plateau even after more than 100 cases, suggesting a continuous improvement of the surgical technique. These findings deserve attention for patient counseling and future comparative studies evaluating functional outcomes after RARP.

Full Text Available Abstract Background Urinary incontinence following acute stroke is common, affecting between 40%-60% of people in hospital after a stroke. Despite the availability of clinical guidelines for urinary incontinence and urinary incontinence after stroke, national audit data suggest incontinence is often poorly managed. Conservative interventions (e.g. bladder training, pelvic floor muscle training and prompted voiding have been shown to have some effect with participants in Cochrane systematic reviews, but have not had their effectiveness demonstrated with stroke patients. Methods/Design A cluster randomised controlled pilot trial designed to assess the feasibility of a full-scale cluster randomised trial and to provide preliminary evidence of the effectiveness and cost-effectiveness of a systematic voiding programme for the management of continence after stroke. Stroke services will be randomised to receive the systematic voiding programme, the systematic voiding programme plus supported implementation, or usual care. The trial aims to recruit at least 780 participants in 12 stroke services (4 per arm. The primary outcome is presence/absence of incontinence at six weeks post-stroke. Secondary outcomes include frequency and severity of incontinence, quality of life and cost-utility. Outcomes will be measured at six weeks, three months and (for participants recruited in the first three months twelve months after stroke. Process data will include rates of recruitment and retention and fidelity of intervention delivery. An integrated qualitative evaluation will be conducted in order to describe implementation and assist in explaining the potential mediators and modifiers of the process.

Two children who had undergone a transappendicular urinary diversion (type Mitrofanoff) developed bladder rupture, one following abdominal trauma, 4 months after the operation and the other following traumatic self-catheterization at 4 years. The clinical history and standard radiological examinations (ultrasonography, cystography) confirmed the diagnosis of urinary peritonitis. Emergency surgical repair was possible in both cases with an uneventful postoperative course. This serious and rare complication requires emergency surgery and justifies rigorous selection of children suitable for this type of diversion giving preference to increased bladder neck resistance over bladder neck closure.

• BACKGROUND: This study was carried out to determine the prevalence and risk factors of urinary incontinence in women aged 30 to 70 years, who were attending to a gynecologic hospital.
• METHODS: During 2006, married women (aged 30-70 years attending to a teaching gynecological hospital were assessed during their visits for any gynecologic diseases. We used a questionnaire with interview for collecting data. The potential risk factors were measured; i.e., the demographics, menopausal status, urinary symptoms (frequency, nocturia and urgency, urinary incontinence, (urgency, stress and mixed, body mass index, medical history (type of delivery, parity, gravidity, chronic illnesses, medication use, pelvic surgery and seeking medical care for their problem.
• RESULTS: The mean age was 46.5 (± 8.4 years. The mean parity was 5.1 ± 1.5. 27% of the participants reported urinary incontinence. Out of 111 women with urinary incontinence, 77 (18.7%, CI: 14.7-22.7%, 17 (4.1%, CI: 2.2-5.8% and 17 (4.1%, CI: 2.2-5.8% were classified as having stress, urge and mixed urinary incontinence, respectively. The overall prevalence of urinary incontinence was 18.9% (34 subjects in women aged 30-44 years, 30.9% (46 subjects in those aged 45-54 years and 37.8% (31 subjects in those aged 55 years and older. Out of 117 menopause women, 39 (33.3% were incontinent. On average, women reported 4.4 (± 1.06 diurnal and 0.55 (± 0.66 nocturnal voidings in 24 hours. Diurnal and nocturnal frequencies were different between continent and incontinent women. The high parity, excessive birth weight, pelvic trauma, constipation, chronic illnesses (specially diabetes and gynecologic and other pelvic surgeries were known as risk factors for urinary incontinence.
• CONCLUSIONS: There was a significant association between urinary incontinence and high parity, excessive birth weight, pelvic

  To quantify changes in surgical practice in the treatment of stress urinary incontinence (SUI), urge urinary incontinence (UUI) and post-prostatectomy stress incontinence (PPI) in England, using the Hospital Episode Statistics (HES) database. We used public domain information from the HES database, an administrative dataset recording all hospital admissions and procedures in England, to find evidence of change in the use of various surgical procedures for urinary incontinence from 2000 to 2012. For the treatment of SUI, a general increase in the use of synthetic mid-urethral tapes, such as tension-free vaginal tape (TVTO) and transobturator tape (TOT), was observed, while there was a significant decrease in colposuspension procedures over the same period. The number of procedures to remove TVT and TOT has also increased in recent years. In the treatment of overactive bladder and UUI, there has been a significant increase in the use of botulinum toxin A and neuromodulation in recent years. This coincided with a steady decline in the recorded use of clam ileocystoplasty. A steady increase was observed in the insertion of artificial urinary sphincter (AUS) devices in men, related to PPI. Mid-urethral synthetic tapes now represent the mainstream treatment of SUI in women, but tape-related complications have led to an increase in procedures to remove these devices. The uptake of botulinum toxin A and sacral neuromodulation has led to fewer clam ileocystoplasty procedures being performed. The steady increase in insertions of AUSs in men is unsurprising and reflects the widespread uptake of radical prostatectomy in recent years. There are limitations to results sourced from the HES database, with potential inaccuracy of coding; however, these data support the trends observed by experts in this field. © 2014 The Authors.

Proctocolectomy with conventional ileostomy cures patients with severe ulcerative colitis but ileostomy appliances must be worn for the rest of their lives. The continent ileostomy, as devised by Kock, provides the patient with an intraabdominal ileal reservoir and a valve constructed by invaginating the efferent ileal segment into the reservoir. The patient empties his reservoir 2-3 times a day by inserting a catheter through the valve. Our experience with 14 patients is reported. The continent ileostomy was in most cases constructed as a second procedure after proctocolectomy. Minor postoperative complications, such as abscess, fistula or partial luxation of the valve were easily corrected. One patient who underwent proctocolectomy and simultaneous construction of a continent ileostomy died in acute liver failure due to a severe preexisting cirrhosis. All the other patients are continent for feces and gas and do not need external appliances. The construction of a continent ileostomy as a secondary procedure can be recommended in patients with proctocolectomy. It offers patients a life situation with differs only insignificantly from that of normal persons.

To assess the existence of therapeutic inertia in the nursing care of patients with urinary incontinence during the patient's time in hospital, together with the sociodemographic and professional variables involved. Inertia in care is a problem which appears in the nursing care process. Actions related to inertia can be attributed to not adhering to protocols, clinical guidelines and the lack of prevention measures which have undesirable effects on the efficiency of care. This was a prospective observational study. A total of 132 nursing professionals participated over two consecutive months. Data were collected randomly through the method of systematic, nonparticipative observation of medical practice units and patients' medical records. The results showed a pattern of severely compromised action in the assessment of the pattern of urinary elimination, in actions related to urinary continence, in therapeutic behaviour and in patient satisfaction and were found to be consistent with professional experience (p inertia exists in nursing care in the hospital environment while the patient is hospitalised, in prevention care, in the treatment of urinary incontinence and in the management of records. Contributing to the understanding of the existence of inertia in nursing care raises questions regarding its causes and interventions to predict or monitor it. © 2018 John Wiley & Sons Ltd.

Raquel Henriques Jácomo

Full Text Available Introduction The International Continence Society (ICS determines that the pelvic floor muscles training (PFMT is the first-choice treatment of urinary symptoms in women. Objective The aim of this study was to systematize randomized controlled clinical trials that address the effects of PFMT in the treatment of urinary symptoms in older women using objective outcome measures. Method Systematic review search was performed eletronic the following databases: Medline, Pubmed, Lilacs, PEDro and manual research conducted in the references of the studies. Were considered eligible women aged over 60 years who performed PFMT in isolation, without the involvement of another technique. The PFMT performed in clinic or at home, with or without the supervision of a therapist and with or without the use of biofeedback as an adjunct. Considered as outcome measures urodynamic studies, voiding diary that assesses daytime urinary frequency, nocturnal urinary frequency, urinary incontinence and exchange absorbent, and, finally, the absorbent test that quantifies loss urinary grams. The assessment of methodological quality of the studies was conducted by PEDro scale. Results Three studies were reviewed in full. Only one trial was rated high methodological quality. There was significant improvement in urinary symptoms after treatment proposed in the three selected studies. Conclusion Considering the studies available so far are weak the evidence for the use of PFMT in the treatment of urinary symptoms in elderly women.

Lepor, Herbert; Kaci, Ledia; Xue, Xiaonan

2004-03-01

We performed a global self-assessment of continence following radical retropubic prostatectomy (RRP) and determined how this global self-assessment of continence correlates with commonly used definitions of continence. Between October 2000 and February 2002 all men who underwent RRP were encouraged to complete the University of California-Los Angeles Prostate Cancer Index 3, 6, 12 and 24 months postoperatively. Beginning October 2002 a single question capturing the patient global self-assessment of continence status was added to the postoperative continence assessment. The study design was cross-sectional since only continence surveys submitted between October 2002 through February 2003 were evaluated. Sensitivity, specificity and kappa coefficient was determined for the relationship between the patient global assessment of continence vs the definition of continence based on pad requirement, problem due to incontinence and frequency of incontinence. Continence progressively improved 3 to 24 months following RRP for all continence outcomes. At 24 months following RRP 97.1% of men considered themselves continent, while 97.1%, 94.1% and 97.1% were considered continent using continence definitions, including the requirement of no or 1 pad in a 24-hour interval, no or slight bother due to incontinence and total control or occasional dribbling, respectively. Our 3 definitions of continence derived from responses to the University of California-Los Angeles Prostate Cancer Index had excellent agreement with patient global self-assessment of continence (kappa coefficients between 0.76 and 0.83). The majority of men achieve continence without invasive intervention following RRP. Final continence status should be ascertained at 24 months. The patient global assessment of continence provides face validity for other definitions of continence based on responses to validated self-administered questionnaires.

The optimal urinary bladder substitute for patients undergoing radical cystectomy is still controversial. The ideal reservoir should provide a large storage capacity at low pressure achieving effective continence with less frequency and minimal renal reflux. In this study we present our experience with W-shaped ileal neo bladder following radical cystectomy. Material and Methods: Between April 1995 and September 1999, a total of 50 male patients underwent lower urinary tract reconstruction following radical cysto prostatectomy by means of ileal W-shaped neo bladder. All patients had invasive bladder cancer proved by preoperative cystoscopy. Their mean age was 45.5 years. The median neo bladder pouch capacity was 420 ml; daytime continence rate was 89.4%, while nighttime continence was noticed in 53.3% of cases. The uretero intestinal anastomoses were performed employing Le Duc technique in all patients. Renal units remained normal in 25 out of 30 evaluated patients. Dilatation of the pelvicalyceal system and the ureter, either unilateral or bilateral occurred in 5/30 of patients (16.6%). These were due to stricture at the urethro or uretero-pouch anastomosis that needed transurethral urethrotomy or revision of the anastomosis; however, renal functions were maintained in all patients. There were three postoperative mortalities (6%) and the early postoperative complications included urinary leakage (6%), prolonged ileus (10%) and deep venous thrombosis (4%). Late complications related to the neo bladder were acceptable including metabolic acidosis (2%). The ileal W-shaped neo bladder is a good choice for male patients after radical cystectomy, provided that there is no evidence of prostatic or urethral tumor invasion

1988-01-01

An alloplastic stoma prosthesis, Biocarbon, composed of 99.9% pure carbon in vitreous form, was used in six patients with conduit urinary diversion and in seven with cutaneous ureterostomy. The patients were thereafter observed for 2-86 months. Complications were subcutaneous infection, urinary fistula and ureteral stenosis, which necessitated removal of the prosthesis in most cases. The permanent stoma, without need for adhesive collecting device, was appreciated by the patients. Problems relating to biocompatibility remain to be solved before the place of the stoma prosthesis in urinary diversion can be determined.

OBJECTIVES To estimate the association between urinary incontinence and glycemic control in women ages 20 to 85. METHODS We included 7,270 women from the 2005–2010 National Health and Nutrition Examination Survey, stratified into three groups of glycemic control defined by hemoglobin A1c (HbA1c): i) those below the diagnostic threshold (HbA1c8.5%) to allow for a different relationship between glycemic control and urinary incontinence within each group. The primary outcomes were the presence of any, only stress, only urgency, and mixed urinary incontinence. We calculated adjusted risk ratios using Poisson regressions with robust variance estimates. RESULTS The survey-weighted prevalence was 52.9% for any, 27.2% for only stress, 9.9% for only urgency, and 15.8% for mixed urinary incontinence. Among women with relatively controlled diabetes, each one-unit increase in HbA1c was associated with a 13% (95% CI: 1.03–1.25) increase for any urinary incontinence and a 34% (95% CI 1.06–1.69) increase in risk for only stress incontinence but was not significantly associated with only urgency and mixed incontinence. Other risk factors included body mass index, hormone replacement therapy, smoking, and physical activity. CONCLUSIONS Worsening glycemic control is associated with an increased risk for stress incontinence for women with relatively controlled diabetes. For those either below the diagnostic threshold or with poorly controlled diabetes, the risk may be driven by other factors. Further prospective investigation of HbA1c as a modifiable risk factor may motivate measures to improve continence in women with diabetes. PMID:26313496

Vaginal position and length in the bitch: relationship to spaying and urinary incontinence

1999-01-01

A study was undertaken to determine if the vagina might be a suitable site for the measurement of intra-abdominal pressure during cystometry in the bitch, The position of the cranial vagina and vaginal length were measured radiographically and the effects of spaying and urinary Incontinence on these variables were evaluated in 30 continent and 30 incontinent bitches. The study used retrograde vaginourethrograms which had been obtained from animals used in a previous study, The cranial vagina was intra-abdominal on 36 of the vaginourethrograms, being least commonly intra-abdominal in incontinent bitches (11/30), Vaginal position was related linearly to vaginal length and continence status (P<0.01), while its length was related to bodyweight(P<0.01). Allowing for bodyweight, neutered animals had significantly shorter vaginas than entire bitches (P<0.01). Measurement of intra-abdominal pressure with concomitant measurement of intravesical pressure is essential if accurate assessment of detrusor pressure is to be determined during cystometry, The vagina is unlikely to be a useful location from which to measure intra-abdominal pressure since any pressure-measuring catheter inserted into it may fall outside the abdominal pressure zone. This is particularly true of neutered and/or incontinent bitches, the groups in which urodynamic investigations of urinary incontinence are most frequently indicated

Convergence across a continent: adaptive diversification in a recent radiation of Australian lizards.

2016-06-15

Recent radiations are important to evolutionary biologists, because they provide an opportunity to study the mechanisms that link micro- and macroevolution. The role of ecological speciation during adaptive radiation has been intensively studied, but radiations can arise from a diversity of evolutionary processes; in particular, on large continental landmasses where allopatric speciation might frequently precede ecological differentiation. It is therefore important to establish a phylogenetic and ecological framework for recent continental-scale radiations that are species-rich and ecologically diverse. Here, we use a genomic (approx. 1 200 loci, exon capture) approach to fit branch lengths on a summary-coalescent species tree and generate a time-calibrated phylogeny for a recent and ecologically diverse radiation of Australian scincid lizards; the genus Cryptoblepharus We then combine the phylogeny with a comprehensive phenotypic dataset for over 800 individuals across the 26 species, and use comparative methods to test whether habitat specialization can explain current patterns of phenotypic variation in ecologically relevant traits. We find significant differences in morphology between species that occur in distinct environments and convergence in ecomorphology with repeated habitat shifts across the continent. These results suggest that isolated analogous habitats have provided parallel ecological opportunity and have repeatedly promoted adaptive diversification. By contrast, speciation processes within the same habitat have resulted in distinct lineages with relatively limited morphological variation. Overall, our study illustrates how alternative diversification processes might have jointly stimulated species proliferation across the continent and generated a remarkably diverse group of Australian lizards. © 2016 The Author(s).

Full Text Available Vesicovaginal fistula (VVF is the abnormal anatomic communication between the female bladder and vagina. Usually presents itself as continuous urinary incontinence. There are many etiologic risk factors such as obstetric trauma, pelvic surgery, infections, congenital abnormalities, foreign materials, malignancy and pelvic radiation (1. Due to high education and sociocultural levels, the incidence seems to be low in the developed countries. On the other hand, in the developing countries, there is an obviously high incidence and prevalence. Considering the low level of medical informative feed-back mechanisms and poor obstetrics health care services, it seems very hard to keep VVF patient data that can be used for epidemiological research studies. In those areas, due to high maternal mortality and obstetric complications, the incidence of VVF is significantly increased (2. In this paper, we report a female patient with known moyamoya disease and a stable right ovarian cyst who was regularly followed up by the departments of neurology, gynecology and presented with radiological and cystoscopy findings of incidentally diagnosed asymptomatic continent VVF.

DOES URINARY DIVERSION IMPROVE THE QUALITY OF LIFE IN OBSTRUCTIVE UROPATHY SECONDARY TO ADVANCED PELVIC MALIGNANCY?

Full Text Available INTRODUCTION The incidence of patients presenting with advanced pelvic malignancy with obstructive uropathy is high in our country. Relentless progress of the malignancy will cause deterioration of renal function, aggravation of pain, infection, deterioration of Quality of Life (QOL, uremia and death. Decreased renal function is considered as a contraindication for palliative chemo and radiotherapy. However urinary diversion in these patients will lead to improvement in renal function and may help in administration of palliative therapy and thus, improve the quality of life of these patients. MATERIALS AND METHODS The present study includes the obstructive uropathy patients secondary to pelvic malignancy referred to our institution for urinary diversion between Jan 2010 to Dec 2014. Total 40 patients were included, of which, 25 patients underwent PCN, 9 patients retrograde DJ stenting, 4 patients refused the treatment, 2 patients were not fit for any intervention due to coagulopathy & comorbid conditions. Of 34 treated patients, 30 were female patients and 4 were male patients. All the patients were explained about the procedure and proper consent taken. Laboratory investigations like CBC, coagulation profile, LFT, routine urine analysis, urine C&S and serum electrolytes were carried out. Haemodialysis was done for 10 patients whose serum creatinine was >6mg% & potassium >6meq. USG guided PCN insertion was done in 8 patients, and in those who failed in this procedure, fluoroscopic C-ARM guided PCN insertion done in 17 patients. Post operatively RFT and serum electrolytes were assessed on 3, 7, 15, & 30th day. PCN catheter was changed once in 3 months. RESULTS 8 patients succeeded in USG guided PCN insertion and 17 patients who failed USG PCN insertion, was done under C–Arm guidance. 3 patients received blood transfusion. No deaths were seen during or post procedure in the hospital. Renal functions improved and normalised in most of the

Electro active polymers : novel bio-electrodes and implants for urinary continence

This paper presented a technical solution to spinal cord injuries that result in urinary bladder dysfunction. It involves miniaturized implants based on polypyrrole, an electroactive polymer, as smart drug-eluting electrodes for neural stimulation to restore bladder function. The nerve-electrode interface is the most vulnerable point in the design and operation of neuro-electronic implants. The main disadvantages are decreased impedance and protein build-up at the stimulation site due to an inflammatory reaction. Polypyrrole is a naturally conducting polymer having both electron-conducting properties as well as actuating properties, rendering it suitable as a drug-eluting electrode for a neurostimulator. Polypyrrole electrochemically coated on platinum increases biocompatibility and reduces electric impedance by increasing the surface area of the electrode. When electrically stimulated, polypyrrole also serves as a matrix to release a negatively-charged anti-inflammatory drug fosfosal. This technology may prove useful in reconstructing a severely damaged bladder through electroactive biomaterials. Polyelectrolyte gels, such as poly(sodium) acrylate, reversibly contract and relax when activated electrically or under the influx of divalent ions. These artificial muscles can be connected to a polypyrrole strain sensor to alert the microcontroller to activate the sphincter muscle, thereby creating an artificial bladder.

Continent cecostomy. An account of 30 patients.

1985-10-01

In this paper, an account is given of our experience with continent colostomy in man. In five patients, the end-sigmoidostomy was provided with an intussusception valve. Evacuation of the bowel by irrigation through a catheter was laborious and time-consuming and this method was abandoned. In another group of 30 patients, the cecum was isolated from the rest of the colon and its distal end was provided with an intussusception valve. Of the 30 patients, eight were later given continent ileostomies, two were converted to conventional sigmoidostomies, and one patient with fecal incontinence preferred to have intestinal continuity reestablished. Thus, 19 patients still have continent cecostomies and are satisfied with their function. When comparing the function of the continent cecostomy with that of the continent ileostomy, however, it is obvious that the ileostomy function is superior. The experience obtained with this group of patients has resulted in a widening of the indications for constructing a continent ileostomy, including selected patients with various anorectal disorders.

To assess morbidity and functional consequences of laparoscopic cystectomy with ileal conduit urinary diversion: in neurologic patients. We reviewed the records of forty-two patients (ten men and thirty-two women) who underwent surgery between August 2007 and October 2013. The median age of the patient was 54 years old (range between 21-79 years). A laparoscopic cystectomy was performed followed by a short laparotomy to perform the ileal conduit urinary diversion. Records were reviewed to retrieve the indications and describe the postoperative and functional course. Patients and GPs were interviewed during phone calls to appreciate the quality of life by the PGII scale in order to assess the functional outcome. The operation was performed on 42 patients, of whom 18 had multiple sclerosis, nine a post-traumatic neurogenic bladder. Among the total population, 10 patients (23.81%) required a transfusion of at least one packed red blood cells (1-7). The overall rate of early complications was 35.71%. Belated complications were seen in 52.38% of the population. The median duration of hospital stay was 16 days (range between 9-70 days). The median follow up was 34 months (range between 1-76 months). For patients, the PGII scale rating had a median value of 6 (2-7). All referring physicians described a better functional status. The laparoscopic cystectomy can make postoperative course smoother for the neurological patients. However, the surgeon must weigh individually the benefit of performing the operation.

Healthcare guidelines are an important vehicle in establishing up-to-date evidence based medicine (EBM) in clinical practice. Due to varying development processes, clinical guidelines created by different institutions can often contain contrasting recommendations. This can have implications for optimal and standardized patient care across management settings. The similarities and differences of treatment recommendations made in the National Institute for Health and Care Excellence (NICE), The European Association of Urology (EAU), and the International Consultation on Continence (ICI) guidelines for neurogenic lower urinary tract dysfunction (NLUTD) were assessed. The guidelines generally agree on their approach to conservative management, including behavioral therapies, and catheterization techniques. There was discrepancy on the benefit of using an alpha blocker in NLUTD and bladder outlet obstruction (BOO) and administering Botulinum toxin A (Onabotulinum-A) in NLUTD. The highest degree of divergence was seen in recommendations for surgical treatments, where the EAU made gender-specific recommendations, and gave continent urinary diversion higher preference than given in the NICE and ICI guidelines. In the absence of high-quality clinical evidence, many of the recommendations made across all three guidelines are based on expert opinion. NICE, the EAU and ICI have similarities but they place differing emphasis on costs and expert opinion, which translated in notably different recommendations. It is evident that increased research efforts, possibly in the form of prospective registries, pragmatic trials, and resource utilization studies are necessary to improve the underlying evidence base for NLUTD, and subsequently the strength and concordance of recommendations across guidelines. © 2018 Wiley Periodicals, Inc.

Congenital cloaca: Long-term follow-up results with emphasis on outcomes beyond childhood.

Science.gov (United States)

Rintala, Risto J

2016-04-01

Persistent cloaca remains a challenge for pediatric surgeons and urologists. Reconstructive surgery of cloacal malformations aims to repair the anorectum, urinary tract, and genital organs, and achieve fecal and urinary continence as well as functional genital tract capable for sexual activity and pregnancy. Unfortunately, even in most experienced hands these goals are not always accomplished. The endpoint of the functional development of bowel, urinary, and genital functions is the completion of patient's growth and sexual maturity. It is unlikely that there will be any significant functional improvement beyond these time points. About half of the patients with cloaca attain fecal and urinary continence after their growth period. The remaining half stay clean or dry by adjunctive measures such as bowel management by enemas or ACE channel, and continent urinary diversion or intermittent catheterization. Problems related to genital organs such as obstructed menstruations, amenorrhea, and introitus stenosis are common and often require secondary surgery. Encouragingly, most adolescent and adult patients are capable of sexual life despite often complex vaginal primary and secondary reconstructions. Also, cloacal malformation does not preclude pregnancies, although they still are quite rare. Pregnant patients with cloaca require special care and follow-up to guarantee uncomplicated pregnancy and preservation of anorectal and urinary functions. Cesarean section is recommended for cloaca patients. The self-reported quality of life of cloaca patients appears to be comparable to that of female patients with less complex anorectal malformations. Copyright © 2016 Elsevier Inc.

Continence difficulties affect the lives of a substantial minority of the population. Women are far more likely than men to be affected by urinary incontinence but the range of management options for them is limited. There has been considerable interest in developing an external urine collection system for women but without success to date. This paper describes the development and preliminary clinical testing of an active urine collection device (AUCD), which could provide a solution for sufferers. The device uses stored vacuum, protected by a high bubble point filter, to remove urine as quickly as it is produced. This allows a small battery-operated pump to provide the required vacuum, enabling the device to be portable. Two different types of non-invasive patient/device interface were developed, and tested by volunteers: urinal and small pad. The slimline urinal was popular with users although liquid noise was a problem. The pad interface was successful on occasions but further work is necessary to produce a reliable pad. This study has successfully demonstrated that a prototype AUCD liquid handling system can remove urine at clinically relevant flowrates. While further development is required, volunteer tests have shown that the AUCD could be a useful advance in continence management.

Robotic Assisted Radical Cystoprostatectomy and Intracorporeal Ileal Conduit Urinary Diversion for a Kidney Transplant Recipient

Directory of Open Access Journals (Sweden)

Peter A. Caputo

Full Text Available ABSTRACT Introduction and Objectives: Robotic assisted radical cystectomy (RARC is an alternative to open radical cystectomy. As experience is gained with the RARC approach the technique is being applied to more complex surgical cases. We describe here our technique for RARC with intracorporeal ileal conduit urinary diversion for a renal transplant recipient. Materials and Methods: The patient is a 60-year old man with high-grade muscle invasive bladder cancer. He has a history of renal failure due to polycystic kidney disease and received a deceased donor renal transplant in 2008. His hospital course at time of transplant was complicated by low-level BK virus viremia. Interestingly his trans-urethral bladder tumor resection specimen at time of bladder cancer diagnosis stained positive for SV40. His native kidneys were anuric so bilateral laparoscopic nephrectomy was performed in a staged fashion 2 weeks prior to RARC. Our surgical technique utilizes 6 trocars, of note a 12-mm assistant trocar is placed 1 cm superior to the pubic symphysis, and this trocar is solely used to pass a laparoscopic stapler to facilitate the excision of the ileal segment and the stapled enteric anastomosis. Surgical steps include: identification of native ureters bilaterally (removed en bloc with the bladder specimen; identification of the transplanted ureter at the right bladder dome; posterior bladder and prostate dissection along Denonvilliers’ fascia; development of the space of Retzius; ligation and transection of the bladder and prostate vascular bundles; apical prostate dissection and transection of urethra; left pelvic lymphadenectomy; ilium resection for creation of the ileal conduit; stapled enteric anastomosis; ureteroileal anastomosis; maturation of the ileal conduit stoma. Results: The surgery had no intraoperative complications. Operative time was 443 minutes (7.4 hours. Estimated blood loss was 250 cc. Length of hospital stay was 5 days. The patient

Treatment of Stress Urinary Incontinence in Neurological Patients With an Injectable Elastomer Prosthesis: Preliminary Results

Directory of Open Access Journals (Sweden)

Julien Renard

Full Text Available Many treatment options for stress urinary incontinence are difficult to apply to neurological patients. Urolastic is a new agent that is primarily indicated for women with mild stress urinary incontinence or men after prostate surgery. In this report, we present a series of 5 cases describing the first use of Urolastic to treat neurological patients. All patients were evaluated with a voiding diary and the use of auxiliary devices as the main indicators of continence. The median operative time was 30.8 minutes, and no complications were observed. Of the 5 patients, 4 reported improved incontinence: 2 switched from diapers to small pads, while the other 2 patients were able to discontinue urinary condom use. The only instance of treatment failure occurred in a patient with a low-compliance bladder. The advantages of this procedure appear to include a soft-cuff effect, reversibility, and minimal invasiveness. However, a future randomized study would be necessary to validate this treatment option.

To estimate the prevalence of urinary incontinence (UI), overactive bladder (OAB), and other lower urinary tract symptoms (LUTS) in the Czech Republic, Russia, and Turkey. Stage one of this population-based survey consisted of computer-assisted telephone interviews to obtain prevalence estimates of storage, voiding, and post-micturition LUTS. Stage two face-to-face interviews evaluated subjects with mixed urinary incontinence (MUI), stress urinary incontinence (SUI) or OAB (case group) and a control group (subjects with other incontinence or LUTS complaints, or no symptoms). Prevalence of LUTS categories were determined for each country based on International Continence Society (ICS) criteria. A total of 3130 individuals agreed to participate in the survey, which found high rates of LUTS (men 80%; women 84%) and OAB (men 18%; women 28%). Duration of urinary symptoms was relatively brief (approximately 60% ≤ 3 years) and was associated with relatively modest effects on quality of life and work performance in the majority of individuals. Forty percent had consulted with a healthcare provider about their urinary symptoms, of whom 37% had consulted with a physician and 34% with an urologist, and 12% had been treated with a prescription medication. Drug therapy, while uncommon, was associated with a high degree of self-reported improvement (96%). Because of between-country population differences, aggregate results may not always be representative of results for each of the three countries individually. Study limitations include reliance on patient self-report, and potential bias introduced by patients who declined to participate in the survey. The results of this epidemiologic survey found high rates of LUTS and OAB, but low levels of medical consultation and very low use of medication treatment, despite high levels of improvement when medications were used.

Evolutionary conservatism and convergence both lead to striking similarity in ecology, morphology and performance across continents in frogs.

Many clades contain ecologically and phenotypically similar species across continents, yet the processes generating this similarity are largely unstudied, leaving fundamental questions unanswered. Is similarity in morphology and performance across assemblages caused by evolutionary convergence or by biogeographic dispersal of evolutionarily conserved ecotypes? Does convergence to new ecological conditions erase evidence of past adaptation? Here, we analyse ecology, morphology and performance in frog assemblages from three continents (Asia, Australia and South America), assessing the importance of dispersal and convergent evolution in explaining similarity across regions. We find three striking results. First, species using the same microhabitat type are highly similar in morphology and performance across both clades and continents. Second, some species on different continents owe their similarity to dispersal and evolutionary conservatism (rather than evolutionary convergence), even over vast temporal and spatial scales. Third, in one case, an ecologically specialized ancestor radiated into diverse ecotypes that have converged with those on other continents, largely erasing traces of past adaptation to their ancestral ecology. Overall, our study highlights the roles of both evolutionary conservatism and convergence in explaining similarity in species traits over large spatial and temporal scales and demonstrates a statistical framework for addressing these questions in other systems.

Association between casual and 24-h urinary sodium-to-potassium (Na/K) ratio is well recognized, although it has not been validated in diverse demographic groups. Our aim was to assess utility across and within populations of casual urine to estimate 24-h urinary Na/K ratio using data from the INTERSALT Study. The INTERSALT Study collected cross-sectional standardized data on casual urinary sodium and potassium and also on timed 24-h urinary sodium and potassium for 10 065 individuals from 52 population samples in 32 countries (1985-87). Pearson correlation coefficients and agreement were computed for Na/K ratio of casual urine against 24-h urinary Na/K ratio both at population and individual levels. Pearson correlation coefficients relating means of 24-h urine and casual urine Na/K ratio were r = 0.96 and r = 0.69 in analyses across populations and individuals, respectively. Correlations of casual urine Na/creatinine and K/creatinine ratios with 24-h urinary Na and K excretion, respectively, were lower than correlation of casual and 24-h urinary Na/K ratio in analyses across populations and individuals. The bias estimate with the Bland-Altman method, defined as the difference between Na/K ratio of 24-h urine and casual urine, was approximately 0.4 across both populations and individuals. Spread around, the mean bias was higher for individuals than populations. With appropriate bias correction, casual urine Na/K ratio may be a useful, low-burden alternative method to 24-h urine for estimation of population urinary Na/K ratio. It may also be applicable for assessment of the urinary Na/K ratio of individuals, with use of repeated measurements to reduce measurement error and increase precision. © The Author 2016.

The effects of involving a nurse practitioner in primary care for adult patients with urinary incontinence: The PromoCon study (Promoting Continence

Directory of Open Access Journals (Sweden)

2008-04-01

Full Text Available Abstract Background Urinary incontinence affects approximately 5% (800.000 of the Dutch population. Guidelines recommend pelvic floor muscle/bladder training for most patients. Unfortunately, general practitioners use this training only incidentally, but prescribe incontinence pads. Over 50% of patients get such pads, costing €160 million each year. Due to ageing of the population a further increase of expenses is expected. Several national reports recommend to involve nurse specialists to support general practitioners and improve patient care. The main objective of our study is to investigate the effectiveness and cost-effectiveness of involving nurse specialists in primary care for urinary incontinence. This paper describes the study protocol. Methods/Design In a pragmatic prospective multi centre two-armed randomized controlled trial in the Netherlands the availability and involvement for the general practitioners of a nurse specialist will be compared with usual care. All consecutive patients consulting their general practitioner within 1 year for urinary incontinence and patients already diagnosed with urinary incontinence are eligible. Included patients will be followed for 12 months. Primary outcome is severity of urinary incontinence (measured with the International Consultation on Incontinence Questionnaire Short Form (ICIQ-UI SF. Based on ICIQ-UI SF outcome data the number of patients needed to include is 350. For the economic evaluation quality of life and costs will be measured alongside the clinical trial. For the longer term extrapolation of the economic evaluation a Markov modelling approach will be used. Discussion/Conclusion This is, to our knowledge, the first trial on care for patients with urinary incontinence in primary care that includes a full economic evaluation and cost-effectiveness modelling exercise from the societal perspective. If this intervention proves to be effective and cost-effective, implementation of this

This study examined how nurses understand urinary problems at the end of life, and identified sources of evidence upon which they base their practice through semi-structured qualitative interviews. The aim was to decide whether research or interventions (such as formulation of best practice guidelines) could improve continence care at the end of life. There is little evidence in nursing literature to indicate how nurses should manage urinary problems at the end of life. Evidence is particularly lacking regarding the insertion of indwelling urinary catheters. This was an applied qualitative interview study which used the 'guided interview' approach. Twelve participants who worked in two hospital wards and one hospice were interviewed about management of patients with urinary problems approaching the end of life. The transcribed interviews were organised using the qualitative analysis software qsr NVivo version 10 (QSR International, Melbourne, Australia). Constant comparison was used to analyse the interviews. The patient and their family were a key concern of all interviewees. Participants focused on processes including: giving care, making decisions, managing uncertainty and assimilating knowledge. These processes are mediated by 'phronesis' or practical wisdom. Within each of the processes (giving care, making decisions, managing uncertainty and assimilating knowledge), participants approached each patient as an individual, using experience, patient wishes, available resources, clinical knowledge and advice from colleagues to provide care. A generalised set of guidelines on managing urinary problems at the end of life would probably not be useful. There is uncertainty about what constitutes best practice in specific areas of continence care at the end of life such as indwelling urinary catheter insertion. A careful approach is needed to ensure that the intellectual and moral knowledge that constitutes practical wisdom is shared and developed throughout teams. �

To assess the safety and efficacy of a single intravesical injection of onabotulinumtoxinA (OnaBTA) for treating urge urinary incontinence (UUI) in women. We performed a prospective case-series study of consecutive patients with refractory UUI treated with an intravesical injection of OnaBTA. The patients were administered 100 units of OnaBTA injected into the bladder wall following 4 weeks of flushing with anticholinergic agents or beta 3 agonists. The urodynamic and clinical endpoints were evaluated before and 6 months after the injection of OnaBTA. The primary study endpoint was the number of episodes of urinary leakage. A total of 204 of the 210 selected patients conducted a valid visit 6 months after the therapeutic application. At 6 months of treatment with OnaBTA, 110 (53.9%) patients remained continent and were considered a success. However, 57 (27.9%) patients experienced one episode of urinary leakage per day, and 37 (18.2%) had 2 or more. In terms of the urodynamic parameters, we observed the following changes: increase in maximum bladder capacity (P<.0001) and reduced maximum pressure of the detrusor (P<.0001). In terms of the safety profile, 8 (3.9%) patients had self-limiting haematuria during the procedure, which resolved spontaneously, and 9 (4.4%) patients had acute urinary retention that required intermittent catheterisation. This study supports the use of OnabotulinumtoxinA in patients with urge urinary incontinence that does not respond to medical treatment. Copyright © 2017 AEU. Publicado por Elsevier España, S.L.U.

Radical cystectomy is the gold-standard treatment for muscle-invasive and refractory nonmuscle-invasive bladder cancer. We describe our technique for robotic radical cystectomy (RRC) and intracorporeal urinary diversion (ICUD), that replicates open surgical principles, and present our preliminary results. Specific descriptions for preoperative planning, surgical technique, and postoperative care are provided. Demographics, perioperative and 30-day complications data were collected prospectively and retrospectively analyzed. Learning curve trends were analyzed individually for ileal conduits (IC) and neobladders (NB). SAS(®) Software Version 9.3 was used for statistical analyses with statistical significance set at P < 0.05. Between July 2010 and September 2013, RRC and lymph node dissection with ICUD were performed in 103 consecutive patients (orthotopic NB=46, IC 57). All procedures were completed robotically replicating the open surgical principles. The learning curve trends showed a significant reduction in hospital stay for both IC (11 vs. 6-day, P < 0.01) and orthotopic NB (13 vs. 7.5-day, P < 0.01) when comparing the first third of the cohort with the rest of the group. Overall median (range) operative time and estimated blood loss was 7 h (4.8-13) and 200 mL (50-1200), respectively. Within 30-day postoperatively, complications occurred in 61 (59%) patients, with the majority being low grade (n = 43), and no patient died. Median (range) nodes yield was 36 (0-106) and 4 (3.9%) specimens had positive surgical margins. Robotic radical cystectomy with totally ICUD is safe and feasible. It can be performed using the established open surgical principles with encouraging perioperative outcomes.

Around 10 % of colorectal cancers are locally advanced at diagnosis. There are higher incidences for sigmoid and rectal cancer adhered to urinary bladder (UB) rather than other segments of colon cancer. Surgeons often performed partial cystectomy as possible for preservation of patient's life quality. This study investigates prognostic factors in patients who underwent bladder preservation en bloc resection for UB adherent colorectal cancer. From 2000 to 2011, 123 patients with clinically UB involvement colorectal cancer underwent primary colorectal cancer with urinary bladder resection. Seventeen patients were excluded because of the concurrent distant metastasis at diagnosis and another 22 patients were excluded because of total cystectomy with uretero-ileal urinary diversion. Finally, 84 patients with clinical stage IIIC (T4bN0M0, according to AJCC 7th edition) that underwent en bloc colorectal cancer resection with partial cystectomy were enrolled into this study for further analysis. Preoperative colovesical fistula and positive CT result were significantly more in the urinary bladder invasion group (p = 0.043 and 0.010, respectively). Pathological UB invasion is an independent predictor of intravesical recurrence (p = 0.04; HR, 10.71; 95 % CI = 1.12∼102.94) and distant metastasis (p = 0.016; HR, 4.85; 95 % CI = 1.34 ∼ 17.53) in multivariate analysis. For bladder preservation en bloc resection of urinary bladder adherent colorectal cancer, the pathological urinary bladder invasion is significantly associated with more urinary bladder recurrence and distant metastasis. This result helps surgeons make decisions at surgical planning and establish follow-up protocol.

There is always a demand for a biocompatible material to repair or substitute the urinary tract instead of using patient’s autologous tissues with its associated morbidity. Biomimetic approaches are tissue-engineering tactics aiming to tailor the material physical and biological properties to behave physiologically similar to the urinary system. This review highlights the different strategies to mimic urinary tissues including modifications in structure, surface chemistry, and cellular response of a range of biological and synthetic materials. The article also outlines the measures to minimize infectious complications, which might lead to graft failure. Relevant experimental and preclinical studies are discussed, as well as promising biomimetic approaches such as three-dimensional bioprinting.

To assess whether crossing rectus abdominis muscle strips, as proposed by Yachia, would change urinary catheterizable conduit's pressure profilometry, in static and dynamic conditions. Non-randomized selection of 20 continent patients that underwent Macedo's ileum-based reservoir, 10 including Yachia's technique (Study Group) and 10 without this mechanism of continence (Control Group). Demographics and cystometric data were assessed. Conduit's pressure profilometry was obtained by infusing saline through a multichannel catheter, at rest and during Valsalva maneuver. We assessed the pressure: (a) in the bladder; (b) in conduit's proximal segment; and (c) in conduit's distal segment, which is presumably the abdominal wall and crossed muscle strips site. Mean age at surgery was 6.1 years in the Control Group and 7.7 years in the Study Group. There was no statistically significant difference between groups regarding maximum cystometric bladder capacity and leakage point pressure. At rest, the pressure profilometry showed similar results between groups in all segments analyzed. During Valsalva maneuver, pressure profilometry showed similar results between groups in bladder and conduit's proximal segment pressure. In this condition, conduit's distal segment pressure in the Study Group (Mean = 72.9 and Peak = 128.7 cmH2 O) was significantly greater (P continence. © 2014 Wiley Periodicals, Inc.

The prayer ritual is an essential component of Islam that requires entry into a state of physical purity (wudhu) through ablution, which is invalidated by voiding. An important dilemma for patients and surgeons may arise when a Muslim patient is counselled on cystectomy because of the belief by some that an incontinent urinary diversion will automatically invalidate their wudhu. To determine if there are any religious barriers and implications for Muslim patients undergoing an incontinent urinary diversion. A questionnaire was distributed to all UK mosques, addressed to the imam (n=804). A total of 134 imams (response rate 16.7%) responded. There was general agreement among imams, with >90% answering that it is possible for a Muslim to perform ablution, pray, and enter a mosque with a urinary stoma. The majority of imams (86.6%) also stated that refusal of a urinary stoma was not justified by religious teachings. When asked if patients should choose the option of a neobladder despite this surgery having greater risk, 57.5% of respondents stated that they were either unsure or agreed with this alternative. The majority of imams agreed that Muslims with a urinary stoma are able to maintain their ablution, allowing them to conduct their daily prayers, and that this form of surgery should not be refused on religious grounds. Our study suggests that the consensus view is that a urinary stoma is not contraindicated with regard to the practice of Islamic prayer rituals. In this study we investigated if having a urinary stoma would be a religious barrier for Muslim patients in performing their obligatory prayer rituals. The overwhelming majority of imams stated that having a urinary stoma should not stop Muslim patients practising important aspects of their faith. Copyright © 2017 European Association of Urology.

The family Gyrodactylidae contains one of the most significant radiations of platyhelminth fish parasites. The so-called hyperviviparity is very rare in the animal kingdom, and the rapid generation time can lead to an explosive population growth, which can cause massive losses in farmed fish. Here we present the first molecular phylogeny including all-but-one African genera, inferred from ITS and 18S rDNA sequences. The validity of nominal genera is discussed in relation to the systematic value of morphological characters traditionally used for generic identification. New complete 18S rDNA sequences of 18 gyrodactylid species of eight genera together with ITS rDNA gene sequences of eight species representing seven genera were generated and complemented with GenBank sequences. The maximum likelihood and Bayesian analyses pointed to a paraphyletic nature of African Gyrodactylus species. They formed well-supported clades possibly indicating speciation within host taxa: (1) parasites of cichlids (Cichlidae); (2) parasites of catfishes (Siluriformes), consisting of a lineage infecting mochokids and one infecting clariids. Macrogyrodactylus spp. firmly clustered into a monophyletic group. We found that Swingleus and Fundulotrema are very closely related and clearly cluster within Gyrodactylus. This supports earlier claims as to the paraphyly of the nominal genus Gyrodactylus as it is currently defined, and necessitates a revision of Swingleus and Fundulotrema. Molecular dating estimates confirmed a relatively young, certainly post-Gondwanan, origin of gyrodactylid lineages. Building on the previously suggested South-American origin of viviparous gyrodactylids, the dataset suggests subsequent intercontinental dispersal to Africa and from there repeated colonisation of the Holarctic. Even though the African continent has been heavily under sampled, the present diversity is far greater than in the intensively studied European fauna, probably because of the high endemicity

Prevention of urinary and anal incontinence: role of elective cesarean delivery.

Science.gov (United States)

Lal, Mira

2003-10-01

Currently, prophylactic elective cesarean to prevent incontinence is being promoted without robust evidence supporting it, this has created confusion among health personnel [corrected]. Past research centered on defining the damaging effect of vaginal birth on continence whilst the limited research on elective cesarean considered it protective. Cesarean delivery has economic, obstetric, gynecological and psychosocial consequences, but incontinence is not uncommon with a persistent morbidity. There is confusion among health personnel about advocating elective cesarean delivery to prevent incontinence. Reviewing current research would facilitate obstetric thinking. Multiplanar endosonography and three-dimensional magnetic resonance imaging scanning are reportedly better in delineating structural alterations in the continence mechanism following vaginal birth and could be applied to postcesarean incontinence. Incontinence can follow vaginal or elective cesarean delivery and the severity following either mode is comparable. Urinary incontinence can resolve, persist or start de novo and the primiparous prevalence is similar following cesarean or vaginal birth. Transient anal incontinence can manifest during pregnancy. Paradoxically, pelvic floor strengthening exercises are beneficial for pregnancy-related incontinence, yet urinary incontinence occurs in nulliparas notwithstanding a strong pelvic floor. Improved imaging techniques should promote a better understanding of postcesarean incontinence. Since severe incontinence can occur after elective cesarean, its reportedly preventative role deserves more scrutiny. When incontinence occurs without labor, it is transient or shows exercise-related improvement; the role of elective cesarean delivery seems tenuous and needs careful evaluation. Current evidence does not support the routine use of elective cesarean to prevent incontinence so the delivery mode should continue to be dictated by obstetric considerations.

CASE DESCRIPTION 3 cats were referred for evaluation of chronic urinary incontinence. CLINICAL FINDINGS A presumptive diagnosis of urethral sphincter mechanism incompetence (USMI) was made in all 3 cats. Preoperatively, incontinence was mild in 1 cat (incontinence during sleep) and moderate to severe (incontinence while awake and at rest) in 2. Structural abnormalities noted during cystoscopy included urethrovestibular junction stenosis (n = 1), vaginal stenosis (1), short urethra (1), and intrapelvic bladder (1). TREATMENT AND OUTCOME All 3 cats were treated by means of implantation of an inflatable silicone hydraulic occluder (HO) via a ventral midline celiotomy. Immediately prior to HO implantation, patients underwent cystoscopy to detect any anatomic abnormalities and confirm the absence of ureteral ectopia. Following surgery, all 3 patients attained complete continence, needing 0 or 1 inflation of the device. Complications included cystoscopy-associated urethral tear (n = 1), constipation (1), stranguria (1), hematuria (2), and urinary tract infection (2). Device explantation was performed 14 weeks after surgery in 1 cat because of postoperative constipation. Constipation persisted and urinary incontinence recurred but was markedly improved following device removal in this cat (leakage of urine only when sleeping at follow-up 29 months after surgery [26 months after device explantation]). At the time of last follow-up, 2 of the 3 cats remained fully continent approximately 3 and 6 years after device implantation. CLINICAL RELEVANCE Findings suggested that implantation of an HO may be a safe and effective long-term treatment for some cats with USMI. Further studies are necessary to evaluate the potential for treatment-related complications and the long-term outcome.

Granese, R; Adile, B

2008-02-01

The aim of this clinic prospective study was to point out the predisposing risk factors for the development of urinary incontinence during pregnancy and postpartum and to understand how to prevent the symptomatology. Sixty seven primipara women at 32 weeks of pregnancy and 3 months after the delivery, were studied through an urogynecological work-up and a questionnaire on the main urinary symptoms. At 32 weeks of pregnancy, 27 patients (40.29%) were affected by stress urinary incontinence (SUI) of type I and 22 (32.83%) by urge incontinence. Three months after delivery, it was observed SUI of type I in 8 patients (15.68%), SUI of type II in 9 patients (17.64%), SUI of type II and II degree cystouretrocele in 3 patients (5.8%) and urge incontinence in 14 patients (27.45%). The most frequent risk factors that were tracked down were: a vaginal delivery, with a prolonged labour, and the episiotomy. We didn't find either substantial changes in the weight between patients continent and incontinent or correlations with the patients' age or with the weight of the foetus and the symptomatology reported. It is important to understand the beginning of the urinary symptoms in the pregnant women, to prevent the worsening of it. It is required, however, a long term follow-up on our patients to verify if the urinary incontinence persists or disappears by the time is needed.

2010-01-01

Full Text Available Background/Aim. Ever since the time when the first orthotopic urinary diversion (pouch was performed there has been a constant improvement and modification of surgical techniques. The aim has been to create a urinary reservoir similar to normal bladder, to decrease incidence of postoperative complications and provide an improved life quality. The aim of this study was to compare postvoiding residual urine (PVR and capacity of the pouch constructed by standard or modified technique. Methods. In this prospective and partially retrospective clinical study we included 79 patients. In the group of 41 patients (group ST pouch was constructed using 50-70 cm of the ileum (standard technique. In the group of 38 patients (group MT pouch was constructed using 25-35 cm of the ileum (modified technique. Postoperatively, PVR and pouch capacity were measured using ultrasound in a 3-, 6- and 12-month period. Results. Postoperatively, an increase in PVR and pouch capacity was noticed in both groups. Twelve months postoperatively, PVR was significantly smaller in the group MT than in the group ST [23 (0-90 mL vs 109 (0-570 mL, p < 0,001]. In the same period the pouch capacity was significantly smaller in the MT group than in the ST group [460 (290-710 mL vs 892 (480-2 050 mL, p < 0.001]. Conclusion. Postoperatively, an increase in PVR and pouch capacity was noticed during a 12-month period. A year following the operation the pouch created from a shorter ileal segment reached capacity of the 'normal' bladder with small PVR. The pouch created by standard technique developed an unnecessary large PVR and capacity.

Bassiouny, M.; El-Sherbiny, M. M.

2003-01-01

The technique and results of a detublarized sigmoid neo bladder for total urinary bladder substitution after radical cystectomy is described. Methods: Fifty one patients (44 men and 7 women) having a mean age of 46 (range, 32-61 years). Radical cysto prostatectomy was performed for the male patients and anterior pelvic exenteration for the female patients. This was followed by total replacement of the bladder with a detubularized sigmoid colon. They were selected to have invasive bladder cancer away from the bladder neck. The mean follow-up period was 38.8 months (range 8-96). Blood chemistry was analyzed periodically every month during the follow-up period. Early and late complications, continence and voiding pattern were recorded. Urodynamic studies were performed every 6 months. Early postoperative complications included, urinary leakage in 7 patients (14%); wound infection in II patients (22%), deep venous thrombosis of the lower extremities in one patient (2%). Late complications included stenosis of the ureterointestinal anastomosis in one patient (2%), stenosis of urethral anastomosis in one patient (2%). A reservoir stone occurred in one patient (2%). No metabolic acidosis nor vitamin B 12 deficiency was reported. The upper urinary tract function was either improved or stable in 96% of cases. However, deterioration occurred in only 4% of cases. All patients could void voluntery without catheterization. Patient satisfaction for continence, by daytime and nighttime (nocturnal continence), was 86% and 72%, respectively. The mean neo bladder capacity and mean residual urine volume was 463.8 ml (range, 275-603) and 93.7 ml (range 50-189), respectively. Pressure flow analysis showed that the mean basal pressure was 5.1 cm H 2 O (range, 1-18) and the mean pressure at maximal capacity was 37.4 cm H 2 O (range, 1-73). The mean maximal flow rate was 17.8 ml/sec (range 3.1-24.5), the mean average flow rate was 11.4 ml/sec. (range 1.9-14.6). The mean first sensation

Proteus mirabilis and Urinary Tract Infections.

Schaffer, Jessica N; Pearson, Melanie M

2015-10-01

Proteus mirabilis is a Gram-negative bacterium and is well known for its ability to robustly swarm across surfaces in a striking bulls'-eye pattern. Clinically, this organism is most frequently a pathogen of the urinary tract, particularly in patients undergoing long-term catheterization. This review covers P. mirabilis with a focus on urinary tract infections (UTI), including disease models, vaccine development efforts, and clinical perspectives. Flagella-mediated motility, both swimming and swarming, is a central facet of this organism. The regulation of this complex process and its contribution to virulence is discussed, along with the type VI-secretion system-dependent intra-strain competition, which occurs during swarming. P. mirabilis uses a diverse set of virulence factors to access and colonize the host urinary tract, including urease and stone formation, fimbriae and other adhesins, iron and zinc acquisition, proteases and toxins, biofilm formation, and regulation of pathogenesis. While significant advances in this field have been made, challenges remain to combatting complicated UTI and deciphering P. mirabilis pathogenesis.

Sexual Function after Non-Nerve-Sparing Radical Cystoprostatectomy: A Comparison between Ileal Conduit Urinary Diversion and Orthotopic Ileal Neobladder Substitution

Full Text Available Objective To compare the erectile function (EF and sexual desire (SD in men after radical cystoprostatectomy (RCP who had either an ileal conduit urinary diversion or orthotropic ileal neobladder substitution. Materials and Methods Eighty one sexually active men with bladder cancer were enrolled in this prospective study. After RCP according to patients' preferences they underwent either ileal conduit urinary diversion (n = 41 or orthotropic ileal neobladder substitution (n = 40. EF and SD were assessed using International Index of Erectile Function (IIEF questionnaire. Patients were assessed at 4-week before surgery and were followed up at 1, 6, and 12-month postoperatively using the same questionnaire. Results Postoperatively the EF and SD domains deteriorated significantly in both groups, but in a small proportion of the patients submitted to ileal neobladder they gradually improved with time (P = 0.006. At 12-month postoperative period, 4 (9.8% and 14 (35.0% patients in ileal conduit and ileal neobladder groups were able to achieve erections hard enough for vaginal penetration and maintained their erection to completion of intercourse, respectively (P = 0.006. Among patients in the ileal conduit and ileal neobladder groups, additional 4 (9.8% and 7 (17.1% patients were able to get some erection, but were unable to maintain their erection to completion of intercourse (P = 0.02. At 12-month follow up period 24.4% of the ileal conduit and 45.0% of the ileal neobladder patients rated their sexual desire very high or high (P = 0.01. Conclusion When performed properly, orthotopic ileal neobladder substitution after RCP offers better long-term results in terms of EF and SD.

This prospective study was conducted to assess functional results obtained after pseudo-continent perineal colostomy using the Schmidt procedure. Functional outcome was assessed in 40 patients who had undergone amputation of the rectum for cancer and pseudo-continent perineal colostomy reconstruction between 1989 and 1995 in our institution. The cancer pathology, operative procedure and post-operative care were noted. Morbidity, functional outcome and degree of patient satisfaction were recorded. Mean follow-up was 45 months (18-87) in 100% of the patients. There were no operative deaths. Twenty patients had post-operative complications and 2 patients required early conversion to definitive abdominal colostomy due to severe perineal complications. Function outcome showed normal continence in 4 patients, air incontinence in 23, occasional minimal leakage in 9 and incontinence requiring iliac colostomy in 2. Eighty-six percent of the patients were highly satisfied or satisfied with their continence capacity. Pseudo-continent perineal colostomy is a reliable technique which can be proposed as an alternative to left iliac colostomy after amputation of the rectum for cancer if a rigorous procedure is applied: careful patient selection, informed consent, rigorous surgical procedure, daily life-long irrigation of the colon.

Full Text Available Introduction: Radical cystectomy is the gold-standard treatment for muscle-invasive and refractory nonmuscle-invasive bladder cancer. We describe our technique for robotic radical cystectomy (RRC and intracorporeal urinary diversion (ICUD, that replicates open surgical principles, and present our preliminary results. Materials and Methods: Specific descriptions for preoperative planning, surgical technique, and postoperative care are provided. Demographics, perioperative and 30-day complications data were collected prospectively and retrospectively analyzed. Learning curve trends were analyzed individually for ileal conduits (IC and neobladders (NB. SAS ® Software Version 9.3 was used for statistical analyses with statistical significance set at P < 0.05. Results: Between July 2010 and September 2013, RRC and lymph node dissection with ICUD were performed in 103 consecutive patients (orthotopic NB=46, IC 57. All procedures were completed robotically replicating the open surgical principles. The learning curve trends showed a significant reduction in hospital stay for both IC (11 vs. 6-day, P < 0.01 and orthotopic NB (13 vs. 7.5-day, P < 0.01 when comparing the first third of the cohort with the rest of the group. Overall median (range operative time and estimated blood loss was 7 h (4.8-13 and 200 mL (50-1200, respectively. Within 30-day postoperatively, complications occurred in 61 (59% patients, with the majority being low grade (n = 43, and no patient died. Median (range nodes yield was 36 (0-106 and 4 (3.9% specimens had positive surgical margins. Conclusions: Robotic radical cystectomy with totally ICUD is safe and feasible. It can be performed using the established open surgical principles with encouraging perioperative outcomes.

Proctocolectomy with conventional ileostomy cures patients with severe ulcerative colitis, however ileostomy appliances had to be worn for the rest of their lives. The continent ileostomy as devised by Kock provides the patient with an intraabdominal ileal reservoir and a valve constructed by invaginating the efferent ileal segment into the reservoir. The patient empties his reservoir 2 to 3 times a day by inserting a catheter through the valve. Our experience with 45 patients is reported. In most cases the continent ileostomy was constructed as a second procedure after proctocolectomy. The construction of a continent ileostomy as a secondary procedure can be recommended in patients with proctocolectomy. It offers patients a life situation differing only insignificantly from that of normal persons.

2015-09-01

The objective of this document created by the ICCS standardization subcommittee is to provide a uniform guideline on measurement, quality control and documentation of urodynamic studies in children. This guideline was created using expert opinion and critical review of the published literature on urodynamic studies in children. Currently no standardized guideline or level 1 data exists on the proper technique for this subject matter. The document provides a throughout explanation on how to approach a child who presents with lower urinary tract dysfunction, whether it be of neurogenic, anatomic or functional origin. Formation of an urodynamic question after a comprehensive history and physical examination is paramount in selecting the urodynamic study(ies) that will be most appropriate for each child. Appropriate application of each test with careful consideration of the needs of the child and family will provide the most accurate and reproducible results. Recommendations on how to execute each of the components of an urodynamic study as well as interpretation are included in the document. Urodynamic studies have become a major tool in evaluating lower urinary tract dysfunction in children. There are many subtleties in performing these studies in children in juxtaposition to adults; therefore, adaptations specific to children must be made to achieve accurate and reproducible results. Uniformity in how the studies are conducted from center to center will allow for healthier transparency and enhanced comparison of results in both clinical and research situations. © 2015 Wiley Periodicals, Inc.

Plant diversity predicts beta but not alpha diversity of soil microbes across grasslands worldwide

Aboveground–belowground interactions exert critical controls on the composition and function of terrestrial ecosystems, yet the fundamental relationships between plant diversity and soil microbial diversity remain elusive. Theory predicts predominantly positive associations but tests within single sites have shown variable relationships, and associations between plant and microbial diversity across broad spatial scales remain largely unexplored. We compared the diversity of plant, bacterial, archaeal and fungal communities in one hundred and forty-five 1 m2 plots across 25 temperate grassland sites from four continents. Across sites, the plant alpha diversity patterns were poorly related to those observed for any soil microbial group. However, plant beta diversity (compositional dissimilarity between sites) was significantly correlated with the beta diversity of bacterial and fungal communities, even after controlling for environmental factors. Thus, across a global range of temperate grasslands, plant diversity can predict patterns in the composition of soil microbial communities, but not patterns in alpha diversity.

Stress urinary incontinence is often associated with prolapse. The suburethral tapes have modified the indication for a preventive treatment of incontinence. The tapes are necessary in case of patent or masked incontinence, discussed in case of potential incontinence. The diagnosis of incontinence is done on questions to the patient, clinical exam, more than in urodynamic study. There is no absolute sign allowing to predict postoperative incontinence after surgery for prolapse. A continent woman can be incontinent postoperatively. If a potential incontinence is treated in the same as the prolapse, the patient must be informed of risk of obstruction and/or urgency.

to assess the urethral closure function by urethral pressure reflectometry (UPR) during intra-abdominal pressure-increase in SUI and continent women. Twenty-five urodynamically proven SUI women and eight continent volunteer women were assessed by ICIQ-SF, pad-weighing test, incontinence diary, and UPR. UPR was conducted during resting and increased intra-abdominal pressure (P(Abd)) by straining. Related values of P(Abd) and urethral opening pressure (P(o)) were plotted into an abdomino-urethral pressuregram. Linear regression of the values was conducted, and the slope of the line ("APIR") and the intercept with the y-axis found. By the equation of the line, Po was calculated for various values of P(Abd), for example, 50 cm H2O (P(o-Abd 50)). The resting P(o) (P(o-rest)) and APIR, respectively, significantly differed in SUI and continent women but could not separate the two groups. The urethral closure equation (UCE) based on P(o-rest) and APIR provided a more detailed characterization of a woman's closure function based on the permanent closure forces (primarily generated by the urethral sphincteric unit) and the adjunctive closure forces (primarily generated by the support system). P(o-Abd 50) and UCE, respectively, which express the combined permanent and adjunctive closure forces and estimate the efficiency of the closure function, separated SUI and continent women and were highly significantly negatively correlated with ICIQ-SF, pad test, and the number of incontinence episodes. New parameters for characterization of the urethral closure function and possible dysfunctions and its efficiency were provided. P(o-Abd 50) and UCE may be used as diagnostic tests and severity measures. © 2013 Wiley Periodicals, Inc.

About one-third of women have urinary incontinence and up to one-tenth have faecal incontinence after childbirth. Pelvic floor muscle training (PFMT) is commonly recommended during pregnancy and after birth for both prevention and treatment of incontinence.This is an update of a review previously published in 2012. To determine the effectiveness of pelvic floor muscle training (PFMT) in the prevention or treatment of urinary and faecal incontinence in pregnant or postnatal women. We searched the Cochrane Incontinence Specialised Register (16 February 2017) and reference lists of retrieved studies. Randomised or quasi-randomised trials in pregnant or postnatal women. One arm of the trial included PFMT. Another arm was no PFMT, usual antenatal or postnatal care, another control condition, or an alternative PFMT intervention. Review authors independently assessed trials for inclusion and risk of bias. We extracted data and checked them for accuracy. Populations included: women who were continent (PFMT for prevention), women who were incontinent (PFMT for treatment) at randomisation and a mixed population of women who were one or the other (PFMT for prevention or treatment). We assessed quality of evidence using the GRADE approach. The review included 38 trials (17 of which were new for this update) involving 9892 women from 20 countries. Overall, trials were small to moderate sized, and the PFMT programmes and control conditions varied considerably and were often poorly described. Many trials were at moderate to high risk of bias. Other than two reports of pelvic floor pain, trials reported no harmful effects of PFMT.Prevention of urinary incontinence: compared with usual care, continent pregnant women performing antenatal PFMT may have had a lower risk of reporting urinary incontinence in late pregnancy (62% less; risk ratio (RR) for incontinence 0.38, 95% confidence interval (CI) 0.20 to 0.72; 6 trials, 624 women; low-quality evidence). Similarly, antenatal PFMT

Double breasting of bladder neck and posterior urethra for continence in isolated peno-pubic epispadias.

The objectives of surgical repair of epispadias include the achievement of urinary continence, cosmetically acceptable genitalia with correction of curvature and normal genital function. To achieve all the aforementioned objectives, patients usually undergo two- or multiple-stage surgeries. Traditionally, the patients undergo epispadias repair in the first stage through modified Cantwell-Ransley or Mitchell-Bagli procedure. Subsequently, in the second stage, bladder neck repair is performed to achieve continence, the most common procedure being modified Young-Dees-Leadbetter. There is no reported single-stage technique of epispadias repair achieving both cosmesis and continence in isolated incontinent epispadias. The objectives of the study were to assess continence and cosmesis with partial penile disassemble and double breasting of bladder neck and posterior urethra in isolated peno-pubic epispadias. A retrospective analysis of surgical outcome of seven cases of primary isolated incontinent peno-pubic epispadias repair from July 2008 to July 2012 was carried out. Patients' age varied from 10 months to 16 years. Penile de-gloving is done with mobilization of urethral plate from ventrum to dorsum, distally till mid-glans and proximally up to pubic symphysis with preservation of blood supply at both ends.

Radical cystectomy followed by urinary diversion or reconstruction (RC) is a standard treatment for patients with muscle-invasive bladder cancer. In these operations, a high frequency of complications, especially postoperative infection, has been reported. However, there have only been a few studies about postoperative anaerobic bacterial infection. To clarify the significance and role of anaerobic bacteria in postoperative infection, we retrospectively analyzed cases in which postoperative infection by these organisms developed. A total of 126 patients who underwent RC from 2006 to 2010 were included in this study. Various types of postoperative infection occurred in 66 patients. Anaerobic bacterial infections were detected with cultures for urine and blood in one case, for blood in two cases, and for surgical wound pus in four. The frequency of postoperative anaerobic bacterial infection in RC was less than that of colon surgery. However, this study revealed the possible development of a nonnegligible number of postoperative anaerobic bacterial infections. Therefore, we should consider anaerobic bacteria as possible pathogens in postoperative infection after RC.

One of the commonest forms of orthotopic bladder substitution for bladder cancer surivors, used in our institute, is the use of ileocecal segment. Sometimes, the need for Indiana pouch heterotropic continent diversion arises. Aim: To compare the long-term effect of orthotopic ileocecal bladder and heterotropic Indiana pouch following radical cystectomy in bladder cancer patients. Patients and methods: Between January 2008 and December 2011, 91 patients underwent radical cystectomy/anterior pelvic exentration and ortho topic ileocecal bladder reconstruction (61 patients) and Indiana pouch (30 patients), when orthotopic diversion could not be technically or oncologically feasible. Results: Convalescence was uneventful in most patients. All minor and major urinary leakage cases, in both diversions groups, where successfully conservatively treated. Only one patient in the ileocecal group with major urinary leak required re-exploration with successful revision of uretro-colonic anastomosis. Only one patient in the Indiana pouch group had accidentally discovered sub-centimetric stone, which was simply expelled. The overall survival proportion of ileocecal group was 100% compared to 80% in the Indiana pouch group (p < 0.001). The disease free survival proportion of ileocecal group was 90.8% compared to 80% in the Indiana pouch group (p = 0.076). Effective comparative daytime and nighttime urinary continence as well as renal function deterioration were not statistically significant between both reconstruction types. Conclusion: Both ileocecal bladder and Indiana pouch are safe procedures in regard to long-term effects over kidney function following radical cystectomy

The purpose of this study was to characterize the urinary microbiota in women who are planning treatment for urgency urinary incontinence and to describe clinical associations with urinary symptoms, urinary tract infection, and treatment outcomes. Catheterized urine samples were collected from multisite randomized trial participants who had no clinical evidence of urinary tract infection; 16S ribosomal RNA gene sequencing was used to dichotomize participants as either DNA sequence-positive or sequence-negative. Associations with demographics, urinary symptoms, urinary tract infection risk, and treatment outcomes were determined. In sequence-positive samples, microbiotas were characterized on the basis of their dominant microorganisms. More than one-half (51.1%; 93/182) of the participants' urine samples were sequence-positive. Sequence-positive participants were younger (55.8 vs 61.3 years old; P = .0007), had a higher body mass index (33.7 vs 30.1 kg/m(2); P = .0009), had a higher mean baseline daily urgency urinary incontinence episodes (5.7 vs 4.2 episodes; P urinary incontinence episodes, -4.4 vs -3.3; P = .0013), and were less likely to experience urinary tract infection (9% vs 27%; P = .0011). In sequence-positive samples, 8 major bacterial clusters were identified; 7 clusters were dominated not only by a single genus, most commonly Lactobacillus (45%) or Gardnerella (17%), but also by other taxa (25%). The remaining cluster had no dominant genus (13%). DNA sequencing confirmed urinary bacterial DNA in many women with urgency urinary incontinence who had no signs of infection. Sequence status was associated with baseline urgency urinary incontinence episodes, treatment response, and posttreatment urinary tract infection risk. Copyright © 2015 Elsevier Inc.

Schaffer, Jessica N.; Pearson, Melanie M.

2015-01-01

Proteus mirabilis is a Gram-negative bacterium which is well-known for its ability to robustly swarm across surfaces in a striking bulls’-eye pattern. Clinically, this organism is most frequently a pathogen of the urinary tract, particularly in patients undergoing long-term catheterization. This review covers P. mirabilis with a focus on urinary tract infections (UTI), including disease models, vaccine development efforts, and clinical perspectives. Flagella-mediated motility, both swimming and swarming, is a central facet of this organism. The regulation of this complex process and its contribution to virulence is discussed, along with the type VI-secretion system-dependent intra-strain competition which occurs during swarming. P. mirabilis uses a diverse set of virulence factors to access and colonize the host urinary tract, including urease and stone formation, fimbriae and other adhesins, iron and zinc acquisition, proteases and toxins, biofilm formation, and regulation of pathogenesis. While significant advances in this field have been made, challenges remain to combatting complicated UTI and deciphering P. mirabilis pathogenesis. PMID:26542036

Maintaining continence lies at the heart of a sense of adulthood and is essential to preserving dignity, a core and universal nursing value. This article explores the reasons why poor continence care was found at Mid Staffordshire Foundation Trust, the changes to the culture of the health service that led to it, and why it is so important for nurses to maintain patients' dignity. Recommendations for changing this culture in the future are discussed.

Although nurses have specialized in the management of incontinence, bladder, bowel, and pelvic floor dysfunction for more than 30 years, there is a lack of awareness and underutilization of their role. This article describes a 6-year project to define, characterize, and validate a role profile of the Nurse Continence Specialist. Data collection used a 2-phase, mixed-methods design. Phase 1 of the project resulted in a draft Nurse Continence Specialist role profile and Phase 2 led to validation of the draft profile. The result was a broad consensus about what constitutes the specific skill set for Nurse Continence Specialist specialization within nursing.

To investigate the efficacy and safety of the Adjustable Transobturator Male System (ATOMS) in men with stress urinary incontinence after transurethral resection of the prostate (TURP). From a large international prospectively administrated ATOMS register, we identified 49 patients with an ATOMS device as a result of persistent stress urinary incontinence after TURP. For evaluation, the men were divided into standard transurethral resection of the prostate (sTURP) and palliative transurethral resection of the prostate (pTURP) in radiated patients. Baseline and follow-up measurements included continence parameters, urodynamics, quality-of-life surveys (Patient Global Impression-Improvement and International Consultation on Incontinence Questionnaire-Short Form), and pain ratings. The dry rate (0-1 security pad/vs 10%, P = .0171) and infection was the most common side effect (50%) observed. Neither intraoperative nor Clavien-Dindo 4 and 5 adverse events were recorded. In sTURP and pTURP, the median daily pad count and the pad test improved significantly (all P <.001), and quality-of-life parameters shifted to a high satisfaction level (P <.001 and P = .001). Urodynamics remained unchanged and postoperative pain was not an issue. The ATOMS device shows promising treatment outcomes in patients after TURP and a similar efficacy as in postprostatectomy incontinence. There is no difference in continence outcome between sTURP and pTURP; however, a higher removal rate was found after pTURP, which may be important for patient counseling.

Contradictory results have been reported regarding most delivery parameters as risk factors for urinary incontinence. We investigated the association between the incidence of urinary incontinence six months postpartum and single obstetric risk factors as well as combinations of risk factors. This study was based on the Norwegian Mother and Child Cohort Study, conducted by the Norwegian Institute of Public Health during 1998-2008. This substudy was based on 7561 primiparous women who were continent before and during pregnancy. Data were obtained from questionnaires answered at weeks 15 and 30 of pregnancy and six months postpartum. Data were linked to the Medical Birth Registry of Norway. Single and combined delivery- and neonatal parameters were analyzed by logistic regression analyses. Birthweight was associated with significantly higher risk of urinary incontinence six months postpartum [3541-4180 g: odds ratio (OR) 1.4, 95% confidence interval (CI) 1.2-1.6; >4180 g: OR 1.6, 95% CI 1.2-2.0]. Fetal presentation, obstetric anal sphincter injuries, episiotomy and epidural analgesia were not significantly associated with increased risk of urinary incontinence. The following combinations of risk factors among women delivering by spontaneous vaginal delivery increased the risk of urinary incontinence six months postpartum; birthweight ≥3540 g and ≥36 cm head circumference; birthweight ≥3540 g and forceps, birthweight ≥3540 g and episiotomy; and ≥36 cm head circumference and episiotomy. Some combinations of delivery parameters and neonatal parameters seem to act together and may increase the risk of incidence of urinary incontinence six months postpartum in a synergetic way. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Artificial urinary sphincter (AUS) AMS-800® is an effective treatment for male stress urinary incontinence. The aim of the study was to assess the long-term effectiveness and complications of artificial urinary sphincter placement preserving the bulbospongiosus muscle. From April 2004 to March 2014, all consecutive male patients with urinary incontinence who underwent an AUS prosthesis insertion were prospectively evaluated. Surgical technique consisted of a perineal incision for cuff placement around the bulbous urethra preserving the bulbospongiosus muscle. Cure rate was defined as no pad use. A total of 82 consecutive patients (median age 68 years, range: 54-78) were prospectively evaluated (median follow-up 46 months, range: 12-135). Bulbospongiosus muscles were preserved intact in all cases with no intraoperative complications. Postoperative complications were reported in 14 patients (1 urethral erosion). The overall cure rate (dry rate) was 76.8% and the median ICIQ-UI score improved from 18 (range: 8-21) to 4 (range: 0-17) (P Artificial urinary sphincter survival rate was 95.5% (95%CI 89.4-100%) at 24 months and 62.6% (95%CI 45.5-79.6%) at 60 months. The mechanical failure rate was 6.3% (median 46.1 months, range: 22.2-100.9) and urethral atrophy and/or inadequate compression rate was 9.5% (median 58.6 months, range: 39-101.4 months). Our study suggests that placement of AUS preserving the bulbospongiosus muscle is technically easy and efficient, reports excellent continence rates and lower urethral erosion rates, and could delay the onset of urethral atrophy compared to other surgical procedures used for sphincter placement. © 2016 Wiley Periodicals, Inc.

Full Text Available Abstract Objective: To characterize a cohort of children with non-neurogenic daytime urinary incontinence followed-up in a tertiary center. Methods: Retrospective analysis of 50 medical records of children who had attained bladder control or minimum age of 5 years, using a structured protocol that included lower urinary tract dysfunction symptoms, comorbidities, associated manifestations, physical examination, voiding diary, complementary tests, therapeutic options, and clinical outcome, in accordance with the 2006 and 2014 International Children's Continence Society standardizations. Results: Female patients represented 86.0% of this sample. Mean age was 7.9 years and mean follow-up was 4.7 years. Urgency (56.0%, urgency incontinence (56.0%, urinary retention (8.0%, nocturnal enuresis (70.0%, urinary tract infections (62.0%, constipation (62.0%, and fecal incontinence (16.0% were the most prevalent symptoms and comorbidities. Ultrasound examinations showed alterations in 53.0% of the cases; the urodynamic study showed alterations in 94.7%. At the last follow-up, 32.0% of patients persisted with urinary incontinence. When assessing the diagnostic methods, 85% concordance was observed between the predictive diagnosis of overactive bladder attained through medical history plus non-invasive exams and the diagnosis of detrusor overactivity achieved through the invasive urodynamic study. Conclusions: This subgroup of patients with clinical characteristics of an overactive bladder, with no history of urinary tract infection, and normal urinary tract ultrasound and uroflowmetry, could start treatment without invasive studies even at a tertiary center. Approximately one-third of the patients treated at the tertiary level remained refractory to treatment.

Teleman, Pia M; Mattiasson, Anders

2007-09-01

Our aim was to compare the urethral pressure response pattern to pelvic floor muscle contractions in 20-27 years old, nulliparous continent women (n = 31) to that of continent (n = 28) and formerly untreated incontinent (n = 59) (53-63 years old) women. These women underwent urethral pressure measurements during rest and repeated pelvic muscle contractions. The response to the contractions was graded 0-4. The young continent women showed a mean urethral pressure response of 2.8, the middle-aged continent women 2.2 (NS vs young continent), and the incontinent women 1.5 (p continent, p continent). Urethral pressures during rest were significantly higher in the younger women than in both groups of middle-aged women. The decreased ability to increase urethral pressure on demand seen in middle-aged incontinent women compared to continent women of the same age as well as young women seems to be a consequence of a neuromuscular disorder rather than of age.

Recurrent urinary tract infections in females

Uncomplicated Urinary tract infections are common in adult women across the entire age spectrum, with mean annual incidence of 15% and 10% in those aged 15-39 and 40-79 years, respectively. Urinary tract infection (UTI), with its diverse clinical syndromes and affected host groups, remains one of the most common but widely misunderstood and challenging infectious diseases encountered in clinical practice. Recurrent urinary tract infections (UTIs) present a significant problem for women and a challenge for the doctors who care for them. The diagnosis of uncomplicated UTI can be achieved best by a thorough assessment of patient symptoms with or without the addition of a urine dipstick test. Treatment should be based on the most recent guidelines, taking into account resistance patterns in the local community. The patient who suffers from recurrent UTIs can be treated safely and effectively with continuous antibiotic prophylaxis, post-coital therapy, or self-initiated treatment. This review article covers the latest trends in the management of recurrent UTI among women. Further research is needed regarding rapid diagnosis of UTI, accurate presumptive identification of patients with resistant pathogens, and development of new antimicrobials for drug-resistant UTI.

To estimate frequency and severity and to identify risk factors of urinary incontinence (UI) and anal incontinence during pregnancy and after delivery in previously continent nulliparous women. We designed a cohort study of healthy, continent, nulliparous pregnant women attending public health care services. The field work was conducted during the control visits of the three trimesters of pregnancy, at the time of delivery, and postpartum. A self-administered questionnaire was used to assess UI (validated and adapted) and anal incontinence. Frequency of UI and anal incontinence and their confidence intervals (95% CIs) were calculated. The correlations between the severity of UI and the degree of effect on daily life were also estimated. Multivariable Cox models were applied to estimate hazard ratios for both incontinences (urinary/anal) during pregnancy and postpartum. The cumulative incidence rate during pregnancy was 39.1% (95% CI 36.3-41.9) for UI and 10.3% (95% CI 8.3-12.3) for anal incontinence. The correlation between severity of UI and effect on daily life was moderate. Age, baseline body mass index, and family history of UI were significantly associated with the occurrence of UI during pregnancy, while age and excess weight gain during pregnancy were associated with the occurrence of anal incontinence during pregnancy. Postpartum, the identified risk factors for both incontinences were incontinence during pregnancy and vaginal delivery. The occurrence of UI and anal incontinence during the postpartum period is related to the presence of incontinence in pregnancy, and vaginal delivery increases the risk of persistent incontinence. Some risk factors for both incontinences during pregnancy and postpartum are related to lifestyles and obstetric practices.

Full Text Available Introduction. Aim of this study was to assess the safety and efficacy of injection of autologous muscle-derived cells into the urinary sphincter for treatment of postprostatectomy urinary incontinence in men and to characterize the injected cells prior to transplantation. Methods. 222 male patients with stress urinary incontinence and sphincter damage after uroloical procedures were treated with transurethral injection of autologous muscle-derived cells. The transplanted cells were investigated after cultivation and prior to application by immunocytochemistry using different markers of myogenic differentiation. Feasibility and functionality assessment was achieved with a follow-up of at least 12 months. Results. Follow-up was at least 12 months. Of the 222 treated patients, 120 responded to therapy of whom 26 patients (12% were continent, and 94 patients (42% showed improvement. In 102 (46% patients, the therapy was ineffective. Clinical improvement was observed on average 4.7 months after transplantation and continued in all improved patients. The cells injected into the sphincter were at least ~50% of myogenic origin and representative for early stages of muscle cell differentiation. Conclusions. Transurethral injection of muscle-derived cells into the damaged urethral sphincter of male patients is a safe procedure. Transplanted cells represent different phases of myogenic differentiation.

Urinary incontinence (UI) is a complication of radical prostatectomy (RP) and transurethral resection of the prostate (TURP). The gold-standard treatment is the artificial urinary sphincter, however, new treatments have been investigated. To examine the outcome of an adjustable transobturator male system (ATOMS ® ) in men with UI after prostatic surgery in a low to medium volume continence center. Twenty-five men with UI were implanted with ATOMS ® system between 2012 and 2014. The most common indication was UI after RP (92%), followed by UI after TURP (8%). Eleven patients (44%) had received adjuvant external beam radiotherapy (RT). Patients were considered to be 'dry' if they stopped wearing pads or needed just one protective pad per day; and improved if the daily number of pads used decreased by at least half. The Incontinence Quality of Life questionnaire (ICIQ-SF) was used, adding a verbal question about the satisfaction of the patient considering the outcome. After a mean follow-up of 21.56 months, 64% were dry and 8% revealed a significant improvement. The success of the procedure was negatively correlated with the severity of the previous UI and with previous treatment with RT. Concerning patients satisfaction, 84% of the patients would repeat the procedure. ATOMS ® offers good rates of cure and improvement of UI after prostatic surgery with a reasonable rate of minor complications. The results of this study, performed in a low to medium volume continence center, are comparable to the results achieved in high volume continence centers. Copyright © 2017 AEU.

Huser, Martin; Belkov, Ivan A; Janku, Petr; Sedlakova, Katerina

2012-11-01

To analyze the available clinical evidence on the continued effectiveness of midurethral sling (MUS) surgery for stress urinary incontinence (SUI) in women who become pregnant and undergo delivery, and then to determine the optimal mode of delivery for such women. An online search was carried out to retrieve the available evidence regarding the risk of SUI recurrence during pregnancy and after delivery following a successful MUS treatment. Appropriate keywords were used to identify all relevant reports published from 1996 through 2011. Basic patient characteristics, mode of delivery, and presence of SUI during pregnancy and the postpartum were analyzed. No more than 36 relevant cases were found. The overall urinary continence rates were 91.7% during pregnancy and 80.6% during the postpartum. Most (58.3%) of the women were delivered vaginally. The evidence indicates that the risk of SUI recurrence is not significantly different after a vaginal or a cesarean delivery. In women successfully treated with a MUS, pregnancy care and delivery mode therefore need to be considered case by case, according to factors other than the risk of recurrence.

An integral theory of female urinary incontinence. Experimental and clinical considerations.

Science.gov (United States)

Petros, P E; Ulmsten, U I

1990-01-01

In this Theory paper, the complex interplay of the specific structures involved in female urinary continence are analyzed. In addition the effects of age, hormones, and iatrogenically induced scar tissue on these structures, are discussed specifically with regard to understanding the proper basis for treatment of urinary incontinence. According to the Theory stress and urge symptoms may both derive, for different reasons from the same anatomical defect, a lax vagina. This laxity may be caused by defects within the vaginal wall itself, or its supporting structures i.e. ligaments, muscles, and their connective tissue insertions. The vagina has a dual function. It mediates (transmits) the various muscle movements involved in bladder neck opening and closure through three separate closure mechanisms. It also has a structural function, and prevents urgency by supporting the hypothesized stretch receptors at the proximal urethra and bladder neck. Altered collagen/elastin in the vaginal connective tissue and/or its ligamentous supports may cause laxity. This dissipates the muscle contraction, causing stress incontinence, and/or activation of an inappropriate micturition reflex, ("bladder instability") by stimulation of bladder base stretch receptors. The latter is manifested by symptoms of frequency, urgency, nocturia with or without urine loss.

This provided an opportunity to review the history of amalgamation and breakup of past super-continents in the Earth's evolution, and speculate on the possibility of future super-continent formation. The largest continent on the present Earth, Eurasia, has been formed from an assembly of several sub-continental blocks including Asia, India and Europe, etc: it is also considered to be the nucleus of a future super-continent expected to form 250 m.y. after the present. In this workshop, several interesting topics were presented regarding the formation process, structure and dynamics of Eurasia, in particular in the deep crust and upper mantle. The first half of the workshop covered structural geology, shallow and deep seismic structure, and a simulation model of the Himalaya-Tibet region, known as a typical ongoing continent-continent collision zone. Inner crustal deformation of Eurasia was demonstrated by a newly developed Discrete Element method. In the latter half of the workshop, the possibility of formation of a future super-continent in the Western Pacific Triangular Zone was introduced with geological interpretation associated with an origin of the hot super-plumes. Seismic tomographic studies, particularly in China, which have revealed interesting features such as low velocity anomalies beneath the volcanic area, together with the presence of subducting Indian plates beneath the Tibet region were introduced. In the northwest Pacific region, remnant subducted slabs of the Kula plate have been found by local seismic tomography. Finally, a review of continental dynamics from gravity studies, and broadband seismic observations in the Baikal rift zones, were presented associated with the tectonics and evolution of central Eurasia. The formation mechanism of a hot super-plume in the

An increasing number of continence procedures are being performed in women of all ages. An overview of the existing literature and consensus regarding surgery for stress urinary incontinence (SUI) in the young and the old was presented and discussed at the International Consultation on Incontinence Research Society Think Tank. This manuscript reflects the Think Tank's summary and opinion. Despite the increasing number of continence procedures, there are relatively few data to guide management in the very young and the very old. When considering continence surgery in the young, long-term efficacy and safety are paramount, and the future effects of pregnancy and childbirth need to be carefully considered. Conversely, in the elderly, minimally invasive procedures with low morbidity are important, especially in the frail elderly who may have significant co-morbidities. Further research including prospective randomised trials, cohort studies and national registries, should help guide our management in these two challenging groups of patients.

Prune belly syndrome has been identified as a clinical triad of abdominal muscle deficiency, bilateral cryptorchidism, and urologic abnormalities. We present the case of a discordant monozygotic twin with prune belly syndrome and voiding dysfunction that was relieved by long-term urinary catheterization by way of the urachus. To the best of our knowledge, this alternative method has not been previously reported. We suggest that for newborn infants with long-term voiding dysfunction, if the urachus retains patency, urinary catheterization through the urachus could be a choice for urine drainage instead of cystostomy, providing a better cosmetic appearance and quality of life.

A Geological Model for the Evolution of Early Continents (Invited)

Geochemical probing of ancient sediments (REE in black shales, strontium composition of carbonates, oxygen isotopes in zircons...) suggests that continents were a late Archean addition at Earth's surface. Yet, geochemical probing of ancient basalts reveals that they were extracted from a mantle depleted of its crustal elements early in the Archean. Considerations on surface geology, the early Earth hypsometry and the rheology and density structure of Archean continents can help solve this paradox. Surface geology: The surface geology of Archean cratons is characterized by thick continental flood basalts (CFBs, including greenstones) emplaced on felsic crusts dominated by Trondhjemite-Tonalite-Granodiorite (TTG) granitoids. This simple geology is peculiar because i/ most CFBs were emplaced below sea level, ii/ after their emplacement, CFBs were deformed into relatively narrow, curviplanar belts (greenstone basins) wrapping around migmatitic TTG domes, and iii/ Archean greenstone belts are richly endowed with gold and other metals deposits. Flat Earth hypothesis: From considerations on early Earth continental geotherm and density structure, Rey and Coltice (2008) propose that, because of the increased ability of the lithosphere to flow laterally, orogenic processes in the Archean produced only subdued topography (continents, Flament et al. (2008) proposed a theory for the hypsometry of the early Earth showing that, until the late Archean, most continents were flooded and Earth was largely a water world. From this, a model consistent with many of the peculiar attributes of Archean geology, can be proposed: 1/ Continents appeared at Earth's surface at an early stage during the Hadean/Archean. However, because they were i/ covered by continental flood basalts, ii/ below sea level, and iii/ deprived of modern-style mountain belts and orogenic plateaux, early felsic

Defining the pattern of genetic diversity of Toxoplasma gondii is important to understand its worldwide distribution. During the last decades, a large number of studies have been published on Toxoplasma genotypes circulating in Europe, in North and South America. Two continents are still largely unexplored, Africa and, to a less extent, Asia. In this last continent, an increasing number of publications reported genotypes circulating in diverse provinces of China, but very few data are available for other Asian countries. After a systematic database search, 47 papers related to T. gondii genotypes in Asia were analyzed. Genetic characterization of DNA was performed by microsatellite markers, or more usually by a multiplex PCR using 11 PCR-RFLP markers, allowing data comparison to draw a first global picture of the population structure of this parasite throughout Asia. Overall, 390 isolates or DNA extracts were completely typed by PCR-RFLP and/or microsatellite marker methods, revealing 36 different PCR-RFLP or equivalent microsatellite genotypes: 15 genotypes identified by a ToxoDB number and 21 atypical or unique genotypes. The most common genotype found in Asia is the genotype ToxoDB#9 (Chinese 1). The clonal types I, II and II variant, and III were also commonly found in Asia. The geographical distribution of these genotypes across Asia may reflect either a continuum with Europe for the western part of Asia (presence of Type II), or the circulation of strains through animal migration or human activities between Africa and the Southwestern part of Asia (Africa 1 genotype in Turkey or ToxoDB#20 both I Sri-Lanka and in Ethiopia or Egypt). Although there are some indications of a genetic population structure in Southeast Asian countries different from the rest of Asia, more studies in this tropical part of Asia will be necessary for a region which represent as well as Africa one of the missing links of the T. gondii genetic diversity.

Urinary incontinence represents involuntary urine leakage into the urethra. This pathological condition represents a major medical, social and hygienic problem. The paper presents risk factors for development of the disorder, as well as diagnostic methods applied in evaluation of the female patients. Chronological review of diverse surgical techniques used in treatment of stress urinary incontinence reported in the published scientific papers is also presented. Review of the literature data was also performed. Sling procedures with application of suburethral loops have been used since the beginning of the last century in treatment of this disorder. Surgical treatment of stress urinary incontinence is applied when conservative treatment fails to give any effects according to strictly defined indications. During the last 100 years, surgical techniques have undergone different improvements and the results have also been significantly improved.

High Prevalence of Stress Urinary Incontinence in Adult Patients with Bronchiectasis

Stress urinary incontinence (SUI) is frequently under-reported in patients with chronic lung disease and may have negative psychosocial consequences. We conducted a prospective study to determine the prevalence, severity and treatment outcomes of SUI in female bronchiectasis patients referred for airway clearance techniques. Nineteen out of 40 (48%) patients reported SUI symptoms. Of these, 14 (74%) reported a reduced quality of life secondary to SUI. Following personalised intervention, symptom improvement was observed in 13\\/19 (68%). Five out of 19 (26%) required specialist referral for further continence care. No associations with lung disease severity and SUI were noted. SUI is common in adult female bronchiectasis patients and should be routinely screened for to improve patients’ overall quality of life.

Preferential rifting of continents - A source of displaced terranes

Science.gov (United States)

Vink, G. E.; Morgan, W. J.; Zhao, W.-L.

1984-01-01

Lithospheric rifting, while prevalent in the continents, rarely occurs in oceanic regions. To explain this preferential rifting of continents, the total strength of different lithospheres is compared by integrating the limits of lithospheric stress with depth. Comparisons of total strength indicate that continental lithosphere is weaker than oceanic lithosphere by about a factor of three. Also, a thickened crust can halve the total strength of normal continental lithosphere. Because the weakest area acts as a stress guide, any rifting close to an ocean-continent boundary would prefer a continental pathway. This results in the formation of small continental fragments or microplates that, once accreted back to a continent during subduction, are seen as displaced terranes. In addition, the large crustal thicknesses associated with suture zones would make such areas likely locations for future rifting episodes. This results in the tendency of new oceans to open along the suture where a former ocean had closed.

To assess the effects of a Pilates exercise program compared to conventional pelvic floor muscle training (PFMT) protocol on pelvic floor muscle strength (PFMS) in patients with post-prostatectomy urinary incontinence. Patients were randomized into three treatment groups (G1: Pilates, G2: electrical stimulation combined with PFMT, and G3: control group). Duration of therapy was 10 weeks. Baseline assessment included the 24 h pad-test and the ICI-Q questionnaire. PFMS was measured using a manometric perineometry device at baseline and 4 months after radical prostatectomy (RP). The level of significance was P  0.05). G1 and G2 achieved a higher number of fully continent patients than G3 (P Pilates method promoted similar outcomes in the proportion of fully continent patients when compared to conventional PFMT 4 months after RP. © 2017 Wiley Periodicals, Inc.

A Review of Recent Developments in the Study of Regional Lithospheric Electrical Structure of the Asian Continent

Science.gov (United States)

Zhang, Letian

2017-09-01

The Asian continent was formed through the amalgamation of several major continental blocks that were formerly separated by the Paleo-Asian and Tethyan Oceans. During this process, the Asian continent underwent a long period of continental crustal growth and tectonic deformation, making it the largest and youngest continent on Earth. This paper presents a review of the application of geophysical electromagnetic methods, mainly the magnetotelluric (MT) method, in recent investigations of the diverse tectonic features across the Asian continent. The case studies cover the major continental blocks of Asia, the Central Asian orogenic system, the Tethyan orogenic system, as well as the western Pacific subduction system. In summary, most of the major continental blocks of Asia exhibit a three-layer structure with a resistive upper crust and upper mantle and a relatively conductive mid-lower crust. Large-scale conductors in the upper mantle were interpreted as an indication of lithospheric modification at the craton margins. The electrical structure of the Central Asian orogenic system is generally more resistive than the bordering continental blocks, whereas the Tethyan orogenic system displays more conductive, with pervasive conductors in the lower crust and upper mantle. The western Pacific subduction system shows increasing complexity in its electrical structure from its northern extent to its southern extent. In general, the following areas of the Asian continent have increasingly conductive lithospheric electrical structures, which correspond to a transition from the most stable areas to the most active tectonic areas of Asia: the major continental blocks, the accretionary Central Asian orogenic system, the collisional Tethyan orogenic system, and the western Pacific subduction system. As a key part of this review, a three-dimensional (3-D) model of the lithospheric electrical structure of a large portion of the Tibetan Plateau is presented and discussed in detail

Few Malagasy children and adults are aware of the rare and unique fauna and flora indigenous to their island-continent, including flagship lemur species. Even the Malagasy ancestral proverbs never mentioned lemurs, but these same proverbs talked about the now extinct hippopotamus. Madagascar's geography, history, and economic constraints contribute to severe biodiversity loss. Deforestation on Madagascar is reported to be over 100,000 ha/year, with only 10-15% of the island retaining natural forest [Green & Sussman, 1990]. Educating children, teacher-training, and community projects about environmental and conservation efforts to protect the remaining natural habitats of endangered lemur species provide a basis for long-term changes in attitudes and practices. Case studies of three conservation education projects located in different geographical regions of Madagascar, Centre ValBio, Madagacar Wildlife Conservation Alaotra Comic Book Project, and The Ako Book Project, are presented together with their ongoing stages of development, assessment, and outcomes. We argue that while nongovernmental organizational efforts are and will be very important, the Ministry of Education urgently needs to incorporate biodiversity education in the curriculum at all levels, from primary school to university.

We present a consensus view of members of the International Children's Continence Society on the therapeutic intervention in congenital neuropatic bladder and bowel dysfunction in children. Discussions were held by a group of pediatric urologists and gastroenterologists appointed by the board. The following draft review document was open to all the ICCS members via the ICCS web site. Feedback was considered by the core authors and by agreement, amendments were made as necessary. The final document is not a systematic literature review. It includes relevant research when available as well as expert opinion on the current understanding of therapeutic intervention in congenital neuropatic bladder and bowel dysfunction in children. Guidelines on pharmalogical and surgical intervention are presented. First the multiple modalities for intervention that do not involve surgical reconstruction are summarized concerning pharmacological agents, medical devices, and neuromodulation. The non-surgical intervention is promoted before undertaking major surgery. Indicators for non-surgical treatments depend on issues related to intravesical pressure, upper urinary tract status, prevalence of urinary tract infections, and the degree of incontinence. The optimal age for treatment of incontinence is also addressed. This is followed by a survey of specific treatments such as anticholinergics, botulinum-A toxin, antibiotics, and catheters. Neuromodulation of the bladder via intravesical electrical stimulation, sacral nerve stimulation, transcutaneous stimulation, and biofeedback is scrutinized. Then follows surgical intervention, which should be tailored to each individual, based on careful consideration of urodynamic findings, medical history, age, and presence of other disability. Treatments mentioned are: urethral dilation, vesicostomy, bladder, augmentation, fascial sling, artificial urinary sphincters, and bladder neck reconstruction and are summarized with regards to success rates

Representations of OxyContin in North American Newspapers and Medical Journals

Emma Whelan

2011-01-01

Full Text Available Following the approval of OxyContin (Purdue Pharma, Canada for medical use, the media began to report the use of OxyContin as a street drug, representing the phenomenon as a social problem. Meanwhile, the pain medicine community has criticized the inaccurate and one-sided media coverage of the OxyContin problem. The authors of this study aimed to contribute to an understanding of both sides of this controversy by analyzing the coverage of OxyContin in newspapers and medical journals. The analyses revealed inconsistent messages about the drug from physicians in the news media and in medical journals, which has likely contributed to the drug’s perception as a social problem. The authors suggest ways to address the lack of medical consensus surrounding OxyContin. The results of this study may help resolve the concerns and conflicts surrounding this drug and other opioids.

We report on the functional results of ortho topic modified T pouch ileal neo bladder, incorporating serous- lined extra mural ileal anti reflux technique for urinary diversion after radical cystectomy. Material and Methods: From September 1998 through November 2001,42 patients of mean age 49 years (range 45-54) having invasive bladder carcinoma underwent radical cystectomy and ortho topic ileal neo bladder urinary diversion, the modified T pouch. Thirty-three patients were males while the remaining 9 were females. The mean follow up was 24 months (range 18-42). Preoperative unior bilateral ureteral dilatation was noted in 13/42 (30.9%) patients). Follow up included clinical examination, laboratory, radiological and uro dynamic investigations. Early postoperative complications were recorded in 3 cases, that were managed conservatively. Day and night continence were achieved in 34/42 (81 %) and 29/42 (69%) patients, night enuresis in 2 (4.8%),while satisfactory day and night continence were noted, respectively. Upper urinary tract (UUT) remained unchanged or improved in all cases. No need for clean intermittent catherization (CIC). No evidence of reflux was detected. Pressure at maximum capacity (average 17 cm H 2 O at 600 ml). Mean flow rate was 17.6 ml/sec (range 15-24). Pelvic cancer recurrence was recorded in 5 patients at mean 24 months, respectively. Modified T pouch has an excellent functional criteria as an ortho topic ileal neo bladder reservoir. It is absolutely indicated in short and/or massively dilated ureter

Straining at stool is an automatic reflex in babies and implies the presence of rectal sensation. We hypothesised that early reported rectal sensation would predict future continence in children with anorectal anomalies. The aim of this study is to determine if early straining at stool was a useful predictor of future continence in infants born with high anorectal malformations. A retrospective case note review of prospectively collected clinical information was performed with institutional review board approval. All patients with intermediate/high anorectal malformation operated on by a single surgeon from 1984 to 2010 were included. After stoma closure, parents were asked: The responses were noted within the first year of stoma closure and then all patients were followed up until they were at least 3 ½years old and continence could be assessed using the Krickenbeck outcome classification. Data were compared using Fisher's exact test and sensitivity, specificity and positive predictive value (PPV) were calculated. Forty-eight patients were included in the study. Sixteen (33%) were female (12 cloacal malformation, 3 rectovaginal fistula, 1 rectal atresia) and 32 (66%) were male (6 rectovesical fistulae, 22 rectourethral fistulae, 4 no fistula). Median follow-up was 9.7years (range 3.5-17.9). Twenty-one children were noted by their parents to exhibit early straining at stool after stoma closure. Twenty of them achieved long term continence. The sensitivity of early straining as a predictor for long term continence was 77%, specificity 95% and positive predictive value 95%. The presence of early rectal sensation reported by parents is a good predictor of long term continence. This allows more informed discussion with families in the early years of life.

Full Text Available OBJECTIVE: In this study, we have gathered the second largest series yet published on laparoscopic radical cystectomy in order to evaluate the incidence and cause of intra and postoperative complication, conversion to open surgery, and patient mortality. MATERIALS AND METHODS: From 1997 to 2005, 59 laparoscopic radical cystectomies were performed for the management of bladder cancer at 3 institutions in South America. Twenty nine patients received continent urinary diversion, including 25 orthotopic ileal neobladders and 4 Indiana pouches. Only one case of continent urinary diversion was performed completely intracorporeally. RESULTS: Mean operative time was 337 minutes (150-600. Estimated intraoperative blood loss was 488 mL (50-1500 and 12 patients (20% required blood transfusion. All 7 (12% intraoperative complications were vascular in nature, that is, 1 epigastric vessel injury, 2 injuries to the iliac vessels (1 artery and 1 vein, and 4 bleedings that occurred during the bladder pedicles control. Eighteen (30% postoperative complications (not counting mortalities occurred, including 3 urinary tract infections, 1 pneumonia, 1 wound infection, 5 ileus, 2 persistent chylous drainage, 3 urinary fistulas, and 3 (5% postoperative complications that required surgical intervention (2 hernias - one in the port site and one in the extraction incision, and 1 bowel obstruction. One case (1.7% was electively converted to open surgery due to a larger tumor that precluded proper posterior dissection. Two mortalities (3.3% occurred in this series, one early mortality due to uncontrolled upper gastrointestinal bleeding and one late mortality following massive pulmonary embolism. CONCLUSIONS: Laparoscopic radical cystectomy is a safe operation with morbidity and mortality rates comparable to the open surgery.

Context Saw palmetto fruit extracts are widely used for treating lower urinary tract symptoms attributed to benign prostatic hyperplasia. However, recent clinical trials have questioned their efficacy, at least at standard doses (320 mg daily). Objective To determine the effect of a saw palmetto extract at up to three times the standard dose on lower urinary tract symptoms attributed to benign prostatic hyperplasia. Design Multicenter placebo-controlled randomized trial conducted from June, 2008 through October, 2010. Setting Eleven North American clinical sites. Participants Were men at least 45 years old, with a peak urinary flow rate ≥ 4 ml/sec, an AUA Symptom Index (AUASI) score ≥ 8 and ≤ 24, and no exclusions. Interventions One, two, and then three 320 mg daily doses of saw palmetto extract or placebo, with dose increases at 24 and 48 weeks. Main Outcome Measures Primary outcome was the difference in AUASI score from baseline to 72 weeks. Secondary outcomes were measures of urinary bother; nocturia; uroflow; postvoid residual; prostate-specific antigen; participants’ global assessments; and indices of sexual function, continence, sleep quality, and prostatitis symptoms. Results From baseline to 72 weeks, mean AUASI scores decreased from 14.4 to 12.2 points with saw palmetto and from 14.7 to 11.7 points with placebo. The group mean difference in AUASI score change from baseline to 72 weeks between the saw palmetto and placebo groups was 0.79 points favoring placebo (bound of the 95% confidence interval most favorable to saw palmetto was 1.77 points, one-sided P=0.91). Saw palmetto was no more effective than placebo for any secondary outcome. No attributable side effects were identified. Conclusions Increasing doses of a saw palmetto fruit extract did not reduce lower urinary tract symptoms more than placebo.

Urinary incontinence and weight change during pregnancy and postpartum: a cohort study.

Science.gov (United States)

Wesnes, Stian Langeland; Hunskaar, Steinar; Bo, Kari; Rortveit, Guri

2010-11-01

Weight gain during pregnancy may contribute to increased urinary incontinence (UI) during and after pregnancy, but scientific support is lacking. The effect of weight loss on UI postpartum is unclear. From 1999 to 2006, investigators in the Norwegian Mother and Child Cohort Study recruited pregnant women during pregnancy. This study was based on 12,679 primiparous women who were continent before pregnancy. Data were obtained from questionnaires answered at weeks 15 and 30 of pregnancy and 6 months postpartum. Weight gain greater than the 50th percentile during weeks 0-15 of pregnancy was weakly associated with higher incidence of UI at week 30 compared with weight gain less than or equal to the 50th percentile. Weight gain greater than the 50th percentile during pregnancy was not associated with increased prevalence of UI 6 months postpartum. For each kilogram of weight loss from delivery to 6 months postpartum among women who were incontinent during pregnancy, the relative risk for UI decreased 2.1% (relative risk = 0.98, 95% confidence interval: 0.97, 0.99). Weight gain during pregnancy does not seem to be a risk factor for increased incidence or prevalence of UI during pregnancy or postpartum. However, weight loss postpartum may be important for avoiding incontinence and regaining continence 6 months postpartum.

Urinary incontinence or the inability to void spontaneously after ileal orthotopic bladder substitution is a frequent finding in female patients. To evaluate how hysterectomy and nerve sparing affect functional outcomes and whether these relate to pre- and postoperative urethral pressure profile (UPP) results. Prospectively performed pre- and postoperative UPPs of 73 female patients who had undergone cystectomy and bladder substitution were correlated with postoperative voiding and continence status. Outcome analyses were performed with the Kruskal-Wallis test, Wilcoxon-Mann-Whitney, or two-group post hoc testing with the Bonferroni correction. Chi-square or Fisher exact tests were applied for the categorical data. Of postoperatively continent or hypercontinent patients, 22 of 43 (51.2%) had the uterus preserved; of incontinent patients, only 4 of 30 (13.3%, pcontinent or hypercontinent patients, 27 of 43 patients (62.8%) had bilateral and 15 of 43 (34.9%) had unilateral attempted nerve sparing. In incontinent patients, 11 of 30 (36.7%) had bilateral and 16 of 30 (53.3%) had unilateral attempted nerve sparing (p=0.02). When compared with postoperatively incontinent patients, postoperatively continent patients had a longer functional urethral length (median: 32mm vs 24mm; prest (56cm H2O vs 35cm H2O; prest (74cm H2O vs 47.5cm H2O; p=0.01). The main limitation was the limited number of patients. In female patients undergoing radical cystectomy and bladder substitution, preservation of the uterus and attempted nerve sparing results in better functional outcomes. The preoperative UPPs correlate with postoperative voiding and continence status and may predict which patients are at a higher risk of functional failure after bladder substitution. If preservation of the urethra's innervation is not possible during cystectomy, poor functional results with bladder substitutes are likely. Copyright © 2015 European Association of Urology.

Functional Resilience against Climate-Driven Extinctions - Comparing the Functional Diversity of European and North American Tree Floras.

Directory of Open Access Journals (Sweden)

Mario Liebergesell

Full Text Available Future global change scenarios predict a dramatic loss of biodiversity for many regions in the world, potentially reducing the resistance and resilience of ecosystem functions. Once before, during Plio-Pleistocene glaciations, harsher climatic conditions in Europe as compared to North America led to a more depauperate tree flora. Here we hypothesize that this climate driven species loss has also reduced functional diversity in Europe as compared to North America. We used variation in 26 traits for 154 North American and 66 European tree species and grid-based co-occurrences derived from distribution maps to compare functional diversity patterns of the two continents. First, we identified similar regions with respect to contemporary climate in the temperate zone of North America and Europe. Second, we compared the functional diversity of both continents and for the climatically similar sub-regions using the functional dispersion-index (FDis and the functional richness index (FRic. Third, we accounted in these comparisons for grid-scale differences in species richness, and, fourth, investigated the associated trait spaces using dimensionality reduction. For gymnosperms we find similar functional diversity on both continents, whereas for angiosperms functional diversity is significantly greater in Europe than in North America. These results are consistent across different scales, for climatically similar regions and considering species richness patterns. We decomposed these differences in trait space occupation into differences in functional diversity vs. differences in functional identity. We show that climate-driven species loss on a continental scale might be decoupled from or at least not linearly related to changes in functional diversity. This might be important when analyzing the effects of climate-driven biodiversity change on ecosystem functioning.

BACKGROUND: There are public concerns regarding OxyContin (Purdue Pharma, Canada) and charges within the pain medicine community that media coverage of the drug has been biased. OBJECTIVE: To analyze and compare representations of OxyContin in medical journals and North American newspapers in an attempt to shed light on how each contributes to the ‘social problem’ associated with OxyContin. METHODS: Using searches of newspaper and medical literature databases, two samples were drawn: 924 stories published between 1995 and 2005 in 27 North American newspapers, and 197 articles published between 1995 and 2007 in 33 medical journals in the fields of addiction/substance abuse, pain/anesthesiology and general/internal medicine. The foci, themes, perspectives represented and evaluations of OxyContin presented in these texts were analyzed statistically. RESULTS: Newspaper coverage of OxyContin emphasized negative evaluations of the drug, focusing on abuse, addiction, crime and death rather than the use of OxyContin for the legitimate treatment of pain. Newspaper stories most often conveyed the perspectives of law enforcement and courts, and much less often represented the perspectives of physicians. However, analysis of physician perspectives represented in newspaper stories and in medical journals revealed a high degree of inconsistency, especially across the fields of pain medicine and addiction medicine. CONCLUSION: The prevalence of negative representations of OxyContin is often blamed on biased media coverage and an ignorant public. However, the proliferation of inconsistent messages regarding the drug from physicians plays a role in the drug’s persistent status as a social problem. PMID:22059195

Spreading continents kick-started plate tectonics.

Stresses acting on cold, thick and negatively buoyant oceanic lithosphere are thought to be crucial to the initiation of subduction and the operation of plate tectonics, which characterizes the present-day geodynamics of the Earth. Because the Earth's interior was hotter in the Archaean eon, the oceanic crust may have been thicker, thereby making the oceanic lithosphere more buoyant than at present, and whether subduction and plate tectonics occurred during this time is ambiguous, both in the geological record and in geodynamic models. Here we show that because the oceanic crust was thick and buoyant, early continents may have produced intra-lithospheric gravitational stresses large enough to drive their gravitational spreading, to initiate subduction at their margins and to trigger episodes of subduction. Our model predicts the co-occurrence of deep to progressively shallower mafic volcanics and arc magmatism within continents in a self-consistent geodynamic framework, explaining the enigmatic multimodal volcanism and tectonic record of Archaean cratons. Moreover, our model predicts a petrological stratification and tectonic structure of the sub-continental lithospheric mantle, two predictions that are consistent with xenolith and seismic studies, respectively, and consistent with the existence of a mid-lithospheric seismic discontinuity. The slow gravitational collapse of early continents could have kick-started transient episodes of plate tectonics until, as the Earth's interior cooled and oceanic lithosphere became heavier, plate tectonics became self-sustaining.

To explore nursing home staff members' beliefs and expectations about what constitutes "quality continence care" for people living in nursing homes. Most nursing home residents require assistance to maintain continence or manage incontinence. Best practice guidelines promote active investigation of incontinence, treatment of underlying potentially reversible causes, and initial conservative interventions to prevent, minimise and/or treat incontinence. Despite research showing the positive benefits of implementing active interventions, translating the findings of research into practice in nursing homes has been modest. Understanding the perspectives of individuals who provide continence care may help bridge the gap between evidence and practice. A qualitative exploratory descriptive design. Qualitative interviews were conducted with 19 nursing home staff: eight registered nurses, four enrolled nurses and seven personal care workers working in a nursing home in Australia between 2014-2015. Data were analysed inductively to identify themes and subthemes that described and explained staff beliefs about quality continence care in nursing homes. Participants' understanding and expectations about quality continence care were linked to beliefs about incontinence being an intractable and undignified condition in nursing homes. The key theme to emerge was "protecting residents' dignity" which was supported by the following six subthemes: (i) using pads, ii) providing privacy, (iii) knowing how to "manage" incontinence, (iv) providing timely continence care, (v) considering residents' continence care preferences and (vi) communicating sensitively. The findings provide new insight into the basis for continence care practices in nursing homes. Education about continence care should challenge beliefs that limit continence care practice to cleaning, containing and concealing incontinence. There is a need for a multidimensional framework that is informed by social, psychological

A unified model of avian species richness on islands and continents.

Kalmar, Attila; Currie, David J

How many species in a given taxon should be found in a delimited area in a specified place in the world? Some recent literature suggests that the answer to this question depends strongly on the geographical, evolutionary, and ecological context. For example, current theory suggests that species accumulate as a function of area differently on continents and islands. Species richness-climate relationships have been examined separately on continents and on islands. This study tests the hypotheses that (1) the functional relationship between richness and climate is the same on continents and islands; (2) the species-area slope depends on distance-based isolation; (3) species-area relationships differ among land bridge islands, oceanic islands, and continents; (4) richness differs among biogeographic regions independently of climate and isolation. We related bird species numbers in a worldwide sample of 240 continental parcels and 346 islands to several environmental variables. We found that breeding bird richness varies similarly on islands and on continents as a function of mean annual temperature, an area x precipitation interaction, and the distance separating insular samples from the nearest continent (R2 = 0.86). Most studies to date have postulated that the slope of the species-area relationship depends upon isolation. In contrast, we found no such interaction. A richness-environment relationship derived using Old World sites accurately predicts patterns of richness in the New World and vice versa (R2 = 0.85). Our results suggest that most of the global variation in richness is not strongly context-specific; rather, it reflects a small number of general environmental constraints operating on both continents and islands.

Achatina fulica (Lissachatina fulica) is one of the most invasive species found across the globe causing a significant damage to crops, vegetables, and horticultural plants. This terrestrial snail is native to east Africa and spread to different parts of the world by introductions. India, a hot spot for biodiversity of several endemic gastropods, has witnessed an outburst of this snail population in several parts of the country posing a serious threat to crop loss and also to human health. With an objective to evaluate the genetic diversity of this snail, we have sampled this snail from different parts of India and analyzed its haplotype diversity by means of 16S rDNA sequence information. Apart from this, we have studied the phylogenetic relationships of the isolates sequenced in the present study in relation with other global populations by Bayesian and Maximum-likelihood approaches. Of the isolates sequenced, haplotype 'C' is the predominant one. A new haplotype 'S' from the state of Odisha was observed. The isolates sequenced in the present study clustered with its conspecifics from the Indian sub-continent. Haplotype network analyses were also carried out for studying the evolution of different haplotypes. It was observed that haplotype 'S' was associated with a Mauritius haplotype 'H', indicating the possibility of multiple introductions of A. fulica to India.

Full Text Available Background: Although the association of urinary lithiasis and urinary tract malformation is not rare, their management poses challenges. The aim of this study was to evaluate the relationship between urolithiasis and malformations of the urinary system. There were 34 patients (19 males and 15 females with a mean age of 4.8 years (range, 2 months to 14 years. All patients had urinary lithiasis with a urinary tract malformation. Abdominal pain was the most frequent clinical symptom (38%. Urinary infection was found in 7 patients (21% and macroscopic haematuria was present in 10 patients (29%. The most frequent urinary tract malformations were megaureter (8 cases, uretero-pelvic junction obstruction (7 cases and vesico-ureteric reflux (8 cases, but its malformative origin could not be confirmed. Treatment consisted of lithiasis extraction in 32 cases associated with specific treatment of the uropathy in 27 cases. Postoperative outcome was uneventful in all cases. In fact, urinary lithiasis and urinary tract malformation association is not rare. Indeed, 9-34% of urinary lithiasis are noted to be associated with urinary tract malformation. Positive diagnosis relies specifically on kidney ultrasound, intravenous urography, and urethrocystography. Treatment depends on the type of urinary tract malformation, localisation and size of the urinary lithiasis. Conclusion: In conclusion, urinary lithiasis and urinary tract malformation association is a frequent eventuality. Surgical intervention is the usual mode of treatment.

Lower urinary tract symptoms (LUTS) can frequently be seen in pregnant women. Pregnancy and delivery have been considered as risk factors in the occurrence of pelvic floor dysfunction and determinants of LUTS. The main associated risk factor is parity. In the present study, we aim to determine the frequency of LUTS and urinary incontinence (UI) during pregnancy and the associated risk factors. This prospective study was carried out in a total of 250 women during their 28- and 40-gestational week checks. The Urinary Distress Inventory-6, the Incontinence Impact Questionnaire-7, and International Consultation on Incontinence Questionnaire-Short Form were used to determine LUTS and its effect on quality of life. The mean age and gestational age of the participants were 29.41 ± 5.70 year (range 18-44) and 35.45 ± 2.98 weeks (range 28-40), respectively. The prevalence of LUTS was 81.6%. The prevalence of UI during pregnancy was 37.2%. Stress urinary incontinence, urge urinary incontinence and mixed urinary incontinence were diagnosed as 15.6, 4.8 and 16.8%, respectively. We found that advanced age, smoking and multiparity were risk factors associated with incontinence. Incontinence reduced pregnant women's quality of life. Lower urinary tract symptoms are commonly seen among pregnant women and these symptoms negatively affect the quality of life of pregnant women. Advanced age, smoking and multiparity were risk factors associated with urinary incontinence and LUTS. Obstetricians should be on the lookout for individual urological problems in pregnancy. Resolving any urological issues and cessation of smoking for the affected individuals will help alleviate the problem. © 2014 Wiley Publishing Asia Pty Ltd.

Full Text Available Abstract Background and objective: Pain relief during labour is an important determinant of a women’s birth experience. There are numerous pain relief techniques which can be used either with or without pain medication. The aim of our study was to compare the effect of remifentanil alone and its effect in pain relief while using with ketamine during labour. Methods: After obtaining informed consent and approval of hospital ethics committee, 40 women with gestational age between 38 and 42 weeks gestation in early labour were recruited for this study. They were randomly allocated into two groups: group RK (20 cases received 25 μg remifentanil as a starting dose and continuous infusion of 0.06 μg/kg/min remifentanil plus 0.5 mg/kg/h ketamine for 4 hours via pump and group R (20 cases received 25 μg remifentanil as a starting dose and continous infusion of 0.06 μg/kg/min remifentanil. Results: The baseline of pain scores were similar in both groups (5.75 ± 2.51 vs 7 ± 2.45, p= 0.12 but after 30 minutes to 120 minutes the VAS scores were significantly higher in R group (p< 0.001. The rate of patients who were satisfied (excellent and very good in RK was 80% but in R group was 45% (p = 0.03. Nausea and vomiting were significantly higher in R group (p<0.05. Conclusion: The remifentanil plus ketamine produced better pain relief during labour with continous monitoring than continous remifentanil with no adverse effects for mothers and infants.

After primary bladder closure or urinary diversion, other factors apart from the reconstruction itself gain importance for individuals with the exstrophy-epispadias complex: social integration and, after reaching puberty, sexuality and fertility. Between 1968 and July 1994 115 patients with bladder exstrophy or incontinent epispadias underwent surgery at our institution. A total of 104 patients could be followed, 2 of whom died in the meantime. Of the remaining 102 patients 48 attend school, 4 are in college, 40 have completed or are currently undergoing vocational training, 3 are unemployed, 1 lives in a therapeutic centre and 6 are younger than 6 years of age. A total of 95% of the patients with continent urinary diversion are continent day and night, whereas only three of five patients with a sling plasty (incontinent epispadias) or with primary bladder closure followed by a Young-Dees procedure are continent. None of the patients showed deterioration or renal function. In 25 females the external genitalia were reconstructed. Fixation of the uterus was done in 13 to correct or prevent uterine prolapse. Of the 17 women older than 18 years of age with genital reconstruction, 16 are satisfied with the cosmetic result. All adults engage in sexual intercourse. Five women have delivered seven children by Caesarean section. Of the 35 male adults 32 underwent reconstruction of the external genitalia and 34 males achieve erection. One developed necrosis of the penis early in life following primary bladder closure performed at an outside hospital. Penile deviation was present in 11 of the 32 patients with genital reconstruction, which is distressing in only 2. Thirty patients are satisfied with the cosmetic result. After genital reconstruction 9 males developed epididymitis, necessitating two orchiectomies and three vasectomies. No patients with reconstruction of the external genitalia can ejaculate normally or has fathered children, whereas ejaculation was normal in the

Problems of fecal elimination are commonly encountered by the pediatric urologist and surgeon. The Malone antegrade continence enema has been described as a means to administer a large volume enema via a continent catheterizable appendicocecostomy, resulting in reliable fecal elimination. Of 22 patients undergoing this procedure 16 reported total continence 4 months or longer after surgery. Complications are relatively minor and tap water appears to be a safe solution for the antegrade continence enema. A nonrefluxing, imbricated appendicocecostomy is preferable to prevent cutaneous fecal or gas leaks.

Virulence factors in Proteus bacteria from biofilm communities of catheter-associated urinary tract infections.

Hola, Veronika; Peroutkova, Tereza; Ruzicka, Filip

More than 40% of nosocomial infections are those of the urinary tract, most of these occurring in catheterized patients. Bacterial colonization of the urinary tract and catheters results not only in infection, but also various complications, such as blockage of catheters with crystalline deposits of bacterial origin, generation of gravels and pyelonephritis. The diversity of the biofilm microbial community increases with duration of catheter emplacement. One of the most important pathogens in this regard is Proteus mirabilis. The aims of this study were to identify and assess particular virulence factors present in catheter-associated urinary tract infection (CAUTI) isolates, their correlation and linkages: three types of motility (swarming, swimming and twitching), the ability to swarm over urinary catheters, biofilm production in two types of media, urease production and adherence of bacterial cells to various types of urinary tract catheters. We examined 102 CAUTI isolates and 50 isolates taken from stool samples of healthy people. Among the microorganisms isolated from urinary catheters, significant differences were found in biofilm-forming ability and the swarming motility. In comparison with the control group, the microorganisms isolated from urinary catheters showed a wider spectrum of virulence factors. The virulence factors (twitching motility, swimming motility, swarming over various types of catheters and biofilm formation) were also more intensively expressed. © 2012 Federation of European Microbiological Societies.

Male urinary incontinence is relatively common complication of radical prostatectomy and of posterior urethroplasty following traumatic pelvic fracture. Here, we investigate the use of pedicled rectus abdominis muscle and fascia flap sling of the bulbar urethra for treatment for male-acquired urinary incontinence. Ten patients with acquired urinary incontinence were included in the study. Urinary incontinence was secondary to TURP in three patients and was secondary to posterior urethroplasty performed following traumatic pelvic fracture in seven patients. Pedicled rectus abdominalis muscle and fascial flaps, approximately 2.5 cm wide and 15 cm long, were isolated. The flaps were inserted into a perineal incision through a subcutaneous tunnel. The free end of the flap was sectioned to form two muscle strips, each 3 cm in length, and inserted into the space between bulbar urethra and corpus cavernosa. After adequate sling tension had been achieved, the two strips of muscle were anastomosed around the bulbar urethra using a 2-zero polyglactin suture. The patients were followed up for between 12 and 82 months (mean 42.8 months). Complete continence was achieved with good voiding in seven of the 10 patients. In other three patients achieved good voiding following catheter removal, but incontinence was only moderately improved. A pedicled rectus muscle fascial sling of the bulbar urethra is an effective and safe treatment for male patients with mild to moderate acquired urinary incontinence, but it may not be suitable for severe incontinence or for patients with weak rectus abdominalis muscles.

Traditionally, urodynamic studies (UDS) have been used to assess lower urinary tract symptoms (LUTS), but their routine use is now discouraged. While urodynamic stress incontinence is strongly associated with the symptom of stress urinary incontinence (SUI) and a positive cough test, there is a weak relationship between symptoms of overactive bladder and detrusor overactivity (DO). The aim of our study was to develop a model to predict DO in women with LUTS. This prospective study included consecutive women with LUTS attending a urodynamic clinic. All women underwent a comprehensive clinical and urodynamic assessment. The effect of each variable on the odds of DO was estimated both by univariate analysis and adjusted analysis using logistic regression. 1006 women with LUTS were included in the study with 374 patients (37%) diagnosed with DO. The factors considered to be the best predictors of DO were urgency urinary incontinence, urge rating/void and parity (p-value<0.01). The absence of SUI, vaginal bulging and previous continence surgery were also good predictors of DO (p-value<0.01). We have created a prediction model for DO based on our best predictors. In our scoring system, presence of UUI scores 5; mean urge rating/void≥3 scores 3; parity≥2 scores 2; previous continence surgery scores -1; presence of SUI scores -1; and the complaint of vaginal bulging scores -1. If a criterion is absent, then the score is 0 and the total score can vary from a value of -3 to +10. The Receiver Operating Characteristic (ROC) analysis for the overall cut-off points revealed an area under the curve of 0.748 (95%CI 0.741, 0.755). This model is able to predict DO more accurately than a symptomatic diagnosis alone, in women with LUTS. The introduction of this scoring system as a screening tool into clinical practice may reduce the need for expensive and invasive tests to diagnose DO, but cannot replace UDS completely.

To investigate the contribution of prolonged labour, method of birth, timing of caesarean section and other obstetric risk factors to postpartum urinary incontinence. Prospective pregnancy cohort. Six metropolitan public hospitals in Victoria, Australia. A total of 1507 nulliparous women recruited to the maternal health study in early pregnancy (≤24 weeks). Data from hospital medical records and self-administered questionnaires/telephone interviews at ≤24 and 30-32 weeks of gestation and 3 months postpartum analysed using univariable and multivariable logistic regression. Urinary incontinence 3 months postpartum in women continent before the index pregnancy. Of the women continent before pregnancy, 26% reported new incontinence at 3 months postpartum. Compared with women who had a spontaneous vaginal birth, women who had a caesarean section before labour (adjusted odds ratio [OR] 0.2, 95% CI 0.1-0.5) or in the first stage of labour (adjusted OR 0.2, 95% CI 0.1-0.4) were less likely to be incontinent 3 months postpartum. Adjusted OR for incontinence after caesarean section in the second stage of labour compared with spontaneous vaginal birth was 0.5 (95% CI 0.2-1.0). Prolonged second stage labour was associated with increased likelihood of postpartum incontinence in women who had a spontaneous vaginal birth (adjusted OR 1.9, 95% CI 1.1-3.4) or operative vaginal birth (adjusted OR 1.7, 95% CI 1.0-2.8). In addition to pregnancy itself, physiological changes associated with the second stage of labour appear to play a role in postpartum urinary incontinence. © 2011 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2011 RCOG.

The long-term failure rate of ileal pouch-anal anastomosis (IPAA) is 10-15%. When salvage surgery is unsuccessful, most surgeons prefer pouch excision with conventional ileostomy, thus sacrificing 40-50 cm of ileum. Conversion of a pelvic pouch to a continent ileostomy (CI, Kock pouch) is an alternative that preserves both the ileal surface and pouch properties. The aim of the study was to evaluate clinical outcome after the construction of a CI following a failed IPAA. During 1984-2007, 317 patients were operated with IPAA at St Olavs Hospital and evaluated for failure, treatment and outcome. Seven patients with IPAA failure had CI. Four patients with IPAA failure referred from other hospitals underwent conversion to CI and are included in the final analysis. Seven patients had a CI constructed from the transposing pelvic pouch and four had the pelvic pouch removed and a new continent pouch constructed from the distal ileum. Median follow up after conversion to CI was 7 years (0-17 years). Two CI had to be removed due to fistulae. One patient needed a revision of the nipple valve due to pouch loosening. At the end of follow-up, 8 of the 11 patients were fully continent. One patient with Crohn's disease had minor leakage. In patients with pelvic pouch failure, the possibility of conversion to CI should be presented to the patient as an alternative to pouch excision and permanent ileostomy. The advantage is the continence and possibly a better body image. Construction of a CI on a new ileal segment may be considered, but the consequences of additional small bowel loss and risk of malnutrition if the Kock pouch fails should be appraised.

Two climate simulations were compared. Both climate computations were initialized with the same horizontally uniform state of rest. However, one is carried out on a water planet (without continents), while the second is repeated on a planet with geographically realistic but flat (sea level) continents. The continents in this experiment have a uniform albedo of 0.14, except where snow accumulates, a uniform roughness height of 0.3 m, and zero water storage capacity. Both runs were carried out for a 'perpetual January' with solar declination fixed at January 15.

Purpose To determine if pelvic soft tissue and bony dimensions on endorectal MRI influence recovery of continence after radical prostatectomy (RP) and whether adding significant MRI variables to a statistical model improves prediction of continence recovery. Materials and Methods Between 2001 and 2004, 967 men undergoing RP had preoperative MRI. Soft tissue and bony dimensions were retrospectively measured by two raters blinded to clinical and pathological data. Patients who received neoadjuvant therapy, were preoperatively incontinent, or had missing followup for continence were excluded, leaving 600 patients eligible for analysis. No pad usage defined continent. Logistic regression was used to identify variables associated with continence recovery at 6 and 12 months. We evaluated whether predictive accuracy of a base model improved by adding independently significant MRI variables. Results Urethral length and urethral volume were both significantly associated with recovery of continence at 6 and 12 months. Larger inner and outer levator distances were significantly associated with a decreased probability of regaining continence at either 6 or 12 months; they did not reach statistical significance for the other time point. Addition of these four MRI variables to a base model including age, clinical stage, PSA and comorbidities marginally improved the discrimination (12 months AUC improved from 0.587 to 0.634). Conclusions Membranous urethral length, urethral volume and an anatomically close relation between the levator muscle and membranous urethra on preoperative MRI are independent predictors of continence recovery after RP. Addition of MRI variables to a base model improved the predictive accuracy for continence recovery but predictive accuracy remains low. PMID:22264458

Full Text Available ABSTRACT Urinary incontinence is a common problem among women and it is estimated that between 15 and 55% of them complain of lower urinary symptoms. The most prevalent form of urinary incontinence is associated with stress, followed by mixed urinary incontinence and urge urinary incontinence. It is a symptom with several effects on quality of life of women mainly in their social, familiar and sexual domains. Female reproductive and urinary systems share anatomical structures, which promotes that urinary problems interfere with sexual function in females. This article is a review of both the concepts of female urinary incontinence and its impact on global and sexual quality of life. Nowadays, it is assumed that urinary incontinence, especially urge urinary incontinence, promotes anxiety and several self-esteem damages in women. The odour and the fear of incontinence during sexual intercourse affect female sexual function and this is related with the unpredictability and the chronicity of incontinence, namely urge urinary incontinence. Female urinary incontinence management involves conservative (pelvic floor muscle training, surgical and pharmacological treatment. Both conservative and surgical treatments have been studied about its benefit in urinary incontinence and also the impact among female sexual function. Unfortunately, there are sparse articles that evaluate the benefits of female sexual function with drug management of incontinence.

The odour and the fear of incontinence during sexual intercourse affect female sexual function and this is related with the unpredictability and the chronicity of incontinence, namely urge urinary incontinence. Female urinary incontinence management involves conservative (pelvic floor muscle training), surgical and pharmacological treatment. Both conservative and surgical treatments have been studied about its benefit in urinary incontinence and also the impact among female sexual function. Unfortunately, there are sparse articles that evaluate the benefits of female sexual function with drug management of incontinence. PMID:28124522

A study is made of the alterations in anorectal physiology among rectal prolapse patients, evaluating the differences between fecal continent and incontinent individuals. Eighteen patients with complete rectal prolapse were divided into two groups: Group A (8 continent individuals) and Group B (10 incontinent women), while 22 healthy women were used as controls (Group C). Clinical exploration and perineal level measurements were performed, along with anorectal manometry, electrophysiology, and anorectal sensitivity to electrical stimuli. The main antecedents of the continent subjects were excess straining efforts, while the incontinent women presented excess straining and complex deliveries. Pathological perineal descent was a frequent finding in both groups, with a hypotonic anal canal at rest (p rest than the continent women (p rest, regardless of whether they are continent to feces or not. Continent patients have less pudendal neuropathy and therefore less pressure alterations at voluntary sphincter squeeze than incontinent individuals.

To explore the mismatch between functional bladder capacity and nocturnal urine production, and to study the pathophysiology of an increased nocturnal urine production in older patients with urinary incontinence. The present prospective observational study included adults aged ≥65 years with urinary incontinence. Participants completed questionnaires, frequency volume charts and renal function profiles. The nocturnal lower urinary tract symptom index was defined as nocturnal urine output/maximum voided volume; the nocturnal polyuria index as nocturnal/24 h urine output. The median age (n = 95) was 74 years (69-79), 87% were women and 73% had nocturnal lower urinary tract symptoms (nocturnal urinary incontinence or nocturia ≥2). Participants with nocturnal lower urinary tract symptoms had a significantly higher nocturnal urine output (809 mL vs 650 mL; P = 0.001) and no significant difference in maximum voided volume (350 mL vs 437 mL; P = 0.079) compared with participants without nocturnal lower urinary tract symptoms. Participants (nocturnal polyuria index >33% [n = 56], nocturnal polyuria index >40% [n = 42], nocturnal lower urinary tract symptom index >1.87 [n = 51]) showed higher night-time diuresis rates, free water and sodium clearance compared with during the daytime. Controls (nocturnal polyuria index ≤33% [n = 26], nocturnal polyuria index ≤40% [n = 40], nocturnal lower urinary tract symptom index ≤1.87 [n = 44]) had no circadian rhythm in their diuresis rate or sodium clearance, but more nocturnal free water clearance compared with during the daytime. The majority of older adults with urinary incontinence present nocturnal lower urinary tract symptoms. An increased nocturnal sodium diuresis seems to be the only mechanism differentiating patients with nocturnal lower urinary tract symptoms from controls. © 2017 The Japanese Urological Association.

Full Text Available Background: Urinary incontinence UI is an involuntary leakage of urine due to loss of bladder control which is a common and often embarrassing problem that may cause tremendous emotional distress. Prevalence and risk factors depend on baseline physiological mechanisms, including weakness of pelvic floor muscles, hyperactive bladder that may result in urge UI, poor urethral sphincter function associated with stress UI, and impaired structural and functional integrity of pudendal nerve activity, associated with Pelvic floor muscle weakness plays an important role in UI etiology. Pelvic floor muscles work to support the bladder neck in the intra- abdominal cavity and maintain urinary continence. Weakness of these muscles leads the bladder to shift to the extra-abdominal cavity and thus a change in the urethra-vesicle angle occurs. Methods: Group (A twenty participants who received behavioral training (BT pelvic floor exercises (PFE and interferential current, group (B twenty participants who received BT, PFE and posterior tibial nerve stimulation, and group (C twenty participants who received BT, PFE and placebo interferential current. Urodynamic and cystometric measures including bladder volume at first desire to void, maximum cystometric capacity, and pressure at maximum flow rate were measured before and after intervention. Results: Results of this study revealed that there was a statistical significant difference in bladder volume at first desire to void, maximum cystometric capacity, and pressure at maximum flow rate in favor of participants who received a combination of BT, PFE and interferential current compared with those who received a combination of BH and PFE with either posterior tibial nerve stimulation or placebo interferential current. Conclusion: Interferential current is better than posterior tibial nerve stimulation in the rehabilitation of urinary incontinence.

To determine the outcomes of pregnancy and cesarean delivery (CD) in women with neuropathic bladder (NB) and pediatric lower urinary tract reconstruction (LUTR) as these women often have normal fertility and may become pregnant. We reviewed consecutive patients with NB due to spinal dysraphism who underwent LUTR, became pregnant, and had a CD at our institution from July 2001 to June 2016. We collected data on demographics, hydronephrosis, symptomatic urinary tract infection, continence, and catheterization during pregnancy. CD data included gestational age, abdominal or uterine incisions, and complications. We identified 18 pregnancies in 11 women. Fifteen live newborns were delivered via CD (53.3% term births). Thirteen of 15 patients (86.7%) developed new (10) or worsening (3) hydronephrosis. Six of 13 patients (46.2%) underwent nephrostomy tube placement. Eight of 15 patients (53.3%) developed difficulty catheterizing (66.7% via native urethra, 44.4% via catheterizable channel); 50.0% of patients required an indwelling catheter. Five of 15 patients (33.3%) developed urinary incontinence during pregnancy. Ten of 15 patients (66.7%) had a urinary tract infection (30.0% febrile). A urologist was present for all CDs: 5 were scheduled, 10 occurred emergently. Complications occurred in 40.0% (5 cystotomies, 1 bowel deserosalization, 1 vaginal laceration). All cystotomies occurred during emergent CD. Three patients (20.0%) developed urinary fistulae after emergent CD. Women with NB and LUTR have high rates of complications during pregnancy and CD, despite routine involvement of urologists. Women with prolonged labor, previous CD, or those with a history of noncompliance developed the worst complications. Based on our experience, a urologist should always be present and participate in the CD. Copyright © 2018 Elsevier Inc. All rights reserved.

Does structural complexity determine the morphology of assemblages? An experimental test on three continents.

Full Text Available Understanding how species will respond to global change depends on our ability to distinguish generalities from idiosyncrasies. For diverse, but poorly known taxa, such as insects, species traits may provide a short-cut to predicting species turnover. We tested whether ant traits respond consistently to habitat complexity across geographically independent ant assemblages, using an experimental approach and baits. We repeated our study in six paired simple and complex habitats on three continents with distinct ant faunas. We also compared traits amongst ants with different foraging strategies. We hypothesised that ants would be larger, broader, have longer legs and more dorsally positioned eyes in simpler habitats. In agreement with predictions, ants had longer femurs and dorsally positioned eyes in simple habitats. This pattern was most pronounced for ants that discovered resources. Body size and pronotum width responded as predicted for experimental treatments, but were inconsistent across continents. Monopolising ants were smaller, with shorter femurs than those that occupied or discovered resources. Consistent responses for several traits suggest that many, but not all, aspects of morphology respond predictably to habitat complexity, and that foraging strategy is linked with morphology. Some traits thus have the potential to be used to predict the direction of species turnover, changes in foraging strategy and, potentially, evolution in response to changes in habitat structure.

Endoscopically placed inlying ureteral stents have proved useful in the conservative management of patients with ureteral obstruction, urinary fistula, and malignancy and have obviated the need for operative intervention. In high-risk symptomatic patients with widespread malignancy, internal urinary diversion offers the opportunity for an improved quality of life without the surgical risk or potential morbidity of supravesical diversion. Potential candidates for this simple, safe, and effective technique include: those with postsurgical obstruction and/or fistula, retroperitoneal fibrosis, metastatic carcinoma, congenital ureteropelvic junction obstruction, as well as those with reversible obstruction from lymphoma and carcinoma of the prostate who are undergoing radiotherapy and/or chemotherapy. The focus of this report is on the technique we have found successful in providing us with stents that fit our individual patients. Readily available fabricated graduated ureteral catheter can be cut and shaped to particular measurements unlike prefabricated catheters. Minimal preparation time is demanded, and there is no need for extensive stocking of various catheter sizes.

Urinary tract infections (UTIs) are common in women and recurrence is a major clinical problem. Most UTIs are caused by uropathogenic Escherichia coli (UPEC). UPEC are generally thought to migrate from the gut to the bladder to cause UTI. UPEC strains form specialized intracellular bacterial communities (IBCs) in the bladder urothelium as part of a pathogenic mechanism to establish a foothold during acute stages of infection. Evolutionarily, such a specific adaptation to the bladder environment would be predicted to result in decreased fitness in other habitats, such as the gut. To examine this concept, we characterized 45 E. coli strains isolated from the feces and urine of four otherwise healthy women with recurrent UTIs. Multi-locus sequence typing revealed that two of the patients maintained a clonal population in both of these body habitats throughout their recurrent UTIs, whereas the other two manifested a wholesale shift in the dominant UPEC strain colonizing their urinary tract and gut between UTIs. These results were confirmed when we subjected 26 isolates from two patients, one representing the persistent clonal pattern and the other representing the dynamic population shift, to whole genome sequencing. In vivo competition studies conducted in mouse models of bladder and gut colonization, using isolates taken from one of the patients with a wholesale population shift, and a newly developed SNP-based method for quantifying strains, revealed that the strain that dominated in her last UTI episode had increased fitness in both body habitats relative to the one that dominated in the preceding episodes. Furthermore, increased fitness was correlated with differences in the strains’ gene repertoires and their in vitro carbohydrate and amino acid utilization profiles. Thus, UPEC appear capable of persisting in both the gut and urinary tract without a fitness tradeoff. Determination of all of the potential reservoirs for UPEC strains that cause recurrent UTI will

Full Text Available Objectives: The aim of this study was to determine the patient and UI-related factors affecting help seeking behavior of Turkish women with undiagnosed urinary incontinence Methods: This cross-sectional study was conducted on 490 female patients aged > 18 years old and were seen in general gynecology outpatients’ clinic of Denizli State Hospital. According to referral complaint and results of UDI-6 questionnaire, the participants were classified into 3 groups: Group A: Help seeker patient, Group B: Non help seeker patient and Group C: Continent patient. Results: Overall UI prevelance was 24%. Nearly two thirds ( 67% of the UI patients do not complaint about their UI symptoms unless they were asked specifically about UI. Consultation rate increased with age, duration of incontinence, menopause and the severity of UI. After logistic regression analyses, only increasing age, UDI-6 score and severity (SSS were found to be associated independently with help seeking behavior. Conclusions: This study showed that, older, more bothered and severe UI patients visit physician and seek medical help. Still nearly half of women who are suffering from clinically significant UI remain undiagnosed and untreated. Regardless the visiting reason if its asked specifically for UI symptoms by using simple questionnaires, we can reveal and diagnose this patients’ group that is suffering from UI but yet keeps it disguise .

To assess the impact of stress urinary incontinence (SUI) on individual components of quality of life (QoL) using both condition-specific and generic questionnaires, and to compare the results of the 2 instruments with a control group. Women with or without SUI aged ≥21 years old were recruited. Subjects completed the International Consultation of Incontinence-Urinary Incontinence Short Form (ICIQ-UI-SF), International Consultation of Incontinence-Lower Urinary Tract Symptoms Quality of Life (ICIQ-LUTSqol), and EQ-5D questionnaires. A total of 120 women with SUI and 145 controls participated. The ICIQ-LUTSqol total score (mean ± standard deviation) was significantly higher in the SUI group (38.96 ± 10.28) compared with the control group (20.78 ± 2.73) (P women with SUI affected "moderately" or "a lot." When measured using the EQ-5D questionnaire, there were significantly higher percentages of patients with SUI who had problems with usual activities, pain or discomfort, and anxiety or depression (P Women suffering from SUI have significantly poorer QoL compared with continent women when measured using both condition-specific and generic QoL measures.

Bladder exstrophy: An overview of the surgical management

Directory of Open Access Journals (Sweden)

Veereshwar Bhatnagar

2011-01-01

Full Text Available Background: The surgical management of urinary bladder exstrophy is challenging. This paper describes the personal experience in a tertiary care hospital over a period exceeding a quarter of a century. Methods: During the period 1984-2010, 248 patients of the epispadias-exstrophy complex have been treated. The cases of classical bladder exstrophy (n = 210 form the basis of this paper. The stages/procedures used in the surgical reconstruction of bladder exstrophy included bladder closure with anterior abdominal wall reconstruction, bladder neck repair, ureteric reimplantation, epispadias repair and augmentation colocystoplasty in various combinations. Some of these patients had their initial operations done prior to 1984 or in other hospitals. Evaluation methods included, amongst others, clinical evaluation and urodynamic assessment. Eight patients opted out of treatment; 15 patients underwent permanent urinary diversion by either ureterosigmoidostomy or colon conduit. The remaining 187 patients were treated with bladder reconstruction, and of these, 132 patients have had at least one attempt at bladder neck reconstruction with 56 of these patients having undergone an augmentation colocystoplasty. Results: A total of 105 patients had socially acceptable continence: 57 from the bladder neck reconstruction group and 48 from the bladder augmentation group. Further attempts at continence surgery have been offered to the inadequately continent patients. Conclusions: Surgical management of bladder exstrophy demands patience and perseverance. It is possible to provide all patients with socially acceptable continence with bladder neck division and catheterizable continent stoma as the last resort. Urodynamic assessment has emerged as an essential tool in the follow-up evaluation of these patients. Anticholinergic medication with imipramine or oxybutinin is a useful adjunct in the overall management.

Urinary incontinence is a highly prevalent condition that impacts self-esteem and overall quality of life. Many non-surgical treatment options are available, ranging from pharmacological approaches to pelvic exercises. We aimed to summarize the available evidence regarding these non-surgical interventions. Review of systematic reviews, conducted in the Discipline of Evidence-Based Medicine, Escola Paulista de Medicina, Universidade Federal de São Paulo (EPM-UNIFESP). A sensitive search was conducted to identify all Cochrane systematic reviews that fulfilled the inclusion criteria. Titles and abstracts were screened by two authors. We included 20 Cochrane systematic reviews: 4 assessing methods of vesical training, 3 evaluating pharmacological interventions, 4 studying pelvic floor muscle training approaches and 9 aimed at other alternatives (such as urethral injections, weighted vaginal cone use, acupuncture, biostimulation and radiofrequency therapy). The reviews found that the evidence regarding the benefits of these diverse interventions ranged in quality from low to high. This review included 20 Cochrane systematic reviews that provided evidence (of diverse quality) for non-pharmacological interventions for patients with urinary incontinence. Moderate to high quality of evidence was found favoring the use of pelvic floor muscle training among women with urinary incontinence. To establish solid conclusions for all the other comparisons, further studies of good methodological quality are needed.

Aboriginal Australians are one of the more poorly studied populations from the standpoint of human evolution and genetic diversity. Thus, to investigate their genetic diversity, the possible date of their ancestors' arrival and their relationships with neighboring populations, we analyzed mitochondrial DNA (mtDNA) diversity in a large sample of Aboriginal Australians. Selected mtDNA single-nucleotide polymorphisms and the hypervariable segment haplotypes were analyzed in 594 Aboriginal Australians drawn from locations across the continent, chiefly from regions not previously sampled. Most (~78%) samples could be assigned to mtDNA haplogroups indigenous to Australia. The indigenous haplogroups were all ancient (with estimated ages >40 000 years) and geographically widespread across the continent. The most common haplogroup was P (44%) followed by S (23%) and M42a (9%). There was some geographic structure at the haplotype level. The estimated ages of the indigenous haplogroups range from 39 000 to 55 000 years, dates that fit well with the estimated date of colonization of Australia based on archeological evidence (~47 000 years ago). The distribution of mtDNA haplogroups in Australia and New Guinea supports the hypothesis that the ancestors of Aboriginal Australians entered Sahul through at least two entry points. The mtDNA data give no support to the hypothesis of secondary gene flow into Australia during the Holocene, but instead suggest long-term isolation of the continent.

2009-12-01

Posterior rhabdosphincter (PR) reconstruction during robot-assisted radical prostatectomy (RARP) was introduced in an attempt to improve postoperative continence. In the present study, we evaluate time to achieve continence in patients who are undergoing RARP with and without PR reconstruction. A prospective RARP database was searched for most recent cases that were accomplished with PR reconstruction (group 1, n = 69) or with standard technique (group 2, n = 63). We performed the analysis applying two definitions of continence: 0 pads per day or 0-1 security pad per day. Patients were evaluated by telephone interview. Statistical analysis was carried out using the Kaplan-Meier method and log-rank test. With PR reconstruction, continence was improved when defined as 0-1 security pad per day (median time of 90 vs 150 days; P = 0.01). This difference did not achieve statistical significance when continence was defined as 0 pads per day (P = 0.12). A statistically significant improvement in continence rate and time to achieve continence is seen in patients who are undergoing PR reconstruction during RARP, with continence defined as 0-1 security/safety pad per day. A larger, prospective and randomized study is needed to better understand the impact of this technique on postoperative continence.

Urinary retention in women.

Juma, Saad

2014-07-01

This review is a summary of the most pertinent published studies in the literature in the last 18 months that address cause, diagnosis, and management of urinary retention in women. Symptoms, uroflow, and pressure-flow studies have a low predictive value for and do not correlate with elevated postvoid residual urine (PVR). Anterior and posterior colporrhaphy do not cause de-novo bladder outlet obstruction in the majority of patients with elevated PVR, and the cause of elevated PVR may be other factors such as pain or anxiety causing abnormal relaxation of the pelvic floor and contributing to voiding difficulty. The risk of urinary retention in a future pregnancy after mid-urethral sling (MUS) is small. The risk of urinary tract infection and urinary retention after chemodenervation of the bladder with onabotulinumtoxin-A (100 IU) in patients with non-neurogenic urge incontinence is 33 and 5%, respectively. There is a lack of consensus among experts on the timing of sling takedown in the management of acute urinary retention following MUS procedures. There has been a significant progress in the understanding of the causation of urinary retention. Important areas that need further research (basic and clinical) are post-MUS and pelvic organ prolapse repair urinary retention and obstruction, and urinary retention owing to detrusor underactivity.

Robotic Assisted Radical Cystectomy with Extracorporeal Urinary Diversion Does Not Show a Benefit over Open Radical Cystectomy: A Systematic Review and Meta-Analysis of Randomised Controlled Trials.

Directory of Open Access Journals (Sweden)

Wei Shen Tan

Full Text Available The number of robotic assisted radical cystectomy (RARC procedures is increasing despite the lack of Level I evidence showing any advantages over open radical cystectomy (ORC. However, several systematic reviews with meta-analyses including non-randomised studies, suggest an overall benefit for RARC compared to ORC. We performed a systematic review with meta-analysis of randomised controlled trials (RCTs to evaluate the perioperative morbidity and efficacy of RARC compared to ORC in patients with bladder cancer.Literature searches of Medline/Pubmed, Embase, Web of Science and clinicaltrials.gov databases up to 10th March 2016 were performed. The inclusion criteria for eligible studies were RCTs which compared perioperative outcomes of ORC and RARC for bladder cancer. Primary objective was perioperative and histopathological outcomes of RARC versus ORC while the secondary objective was quality of life assessment (QoL, oncological outcomes and cost analysis.Four RCTs (from 5 articles met the inclusion criteria, with a total of 239 patients all with extracorporeal urinary diversion. Patient demographics and clinical characteristics of RARC and ORC patients were evenly matched. There was no significant difference between groups in perioperative morbidity, length of stay, positive surgical margin, lymph node yield and positive lymph node status. RARC group had significantly lower estimated blood loss (p<0.001 and wound complications (p = 0.03 but required significantly longer operating time (p<0.001. QoL was not measured uniformly across trials and cost analysis was reported in one RCTs. A test for heterogeneity did highlight differences across operating time of trials suggesting that surgeon experience may influence outcomes.This study does not provide evidence to support a benefit for RARC compared to ORC. These results may not have inference for RARC with intracorporeal urinary diversion. Well-designed trials with appropriate endpoints conducted

Boyle, Diane K; Bergquist-Beringer, Sandra; Cramer, Emily

The purpose of this study was to describe the (a) number and types of employed WOC certified nurses in acute care hospitals, (b) rates of hospital-acquired pressure injury (HAPI) and catheter-associated urinary tract infection (CAUTI), and (c) effectiveness of WOC certified nurses with respect to lowering HAPI and CAUTI occurrences. Retrospective analysis of data from National Database of Nursing Quality Indicators. The sample comprised 928 National Database of Nursing Quality Indicators (NDNQI) hospitals that participated in the 2012 NDNQI RN Survey (source of specialty certification data) and collected HAPI, CAUTI, and nurse staffing data during the years 2012 to 2013. We analyzed years 2012 to 2013 data from the NDNQI. Descriptive statistics summarized the number and types of employed WOC certified nurses, the rate of HAPI and CAUTI, and HAPI risk assessment and prevention intervention rates. Chi-square analyses were used to compare the characteristics of hospitals that do and do not employ WOC certified nurses. Analysis-of-covariance models were used to test the association between WOC certified nurses and HAPI and CAUTI occurrences. Just more than one-third of the study hospitals (36.6%) employed WOC certified nurses. Certified continence care nurses (CCCNs) were employed in fewest number. Hospitals employing wound care specialty certified nurses (CWOCN, CWCN, and CWON) had lower HAPI rates and better pressure injury risk assessment and prevention practices. Stage 3 and 4 HAPI occurrences among hospitals employing CWOCNs, CWCNs, and CWONs (0.27%) were nearly half the rate of hospitals not employing these nurses (0.51%). There were no significant relationships between nurses with specialty certification in continence care (CWOCN, CCCN) or ostomy care (CWOCN, COCN) and CAUTI rates. CWOCNs, CWCNs, and CWONs are an important factor in achieving better HAPI outcomes in acute care settings. The role of CWOCNs, CCCNs, and COCNs in CAUTI prevention warrants further

Lower urinary tract dysfunction is a common pediatric urological problem that is often associated with urinary tract infection. We determined the prevalence of a urinary tract infection history in children with lower urinary tract dysfunction and its association, if any, with gender, bowel dysfunction, vesicoureteral reflux and specific lower urinary tract conditions. We retrospectively reviewed the charts of children diagnosed with and treated for lower urinary tract dysfunction, noting a history of urinary tract infection with or without fever, gender, bowel dysfunction and vesicoureteral reflux in association with specific lower urinary tract conditions. Of the 257 boys and 366 girls with a mean age of 9.1 years 207 (33%) had a urinary tract infection history, including 88 with at least 1 febrile infection. A total of 64 patients underwent voiding cystourethrogram/videourodynamics, which revealed reflux in 44 (69%). In 119 of the 207 patients all infections were afebrile and 18 underwent voiding cystourethrogram/videourodynamics, which revealed reflux in 5 (28%). A urinary tract infection history was noted in 53% of girls but only 5% of boys (p infection history than patients with idiopathic detrusor overactivity disorder or primary bladder neck dysfunction (each p urinary tract dysfunction have a much higher urinary tract infection incidence than males. This association was most often noted for lower urinary tract conditions in which urinary stasis occurs, including detrusor underutilization disorder and dysfunctional voiding. Reflux was found in most girls with a history of febrile infections. Since reflux was identified in more than a quarter of girls with only afebrile infections who were evaluated for reflux, it may be reasonable to perform voiding cystourethrogram or videourodynamics in some of them to identify reflux.

Saw palmetto fruit extracts are widely used for treating lower urinary tract symptoms attributed to benign prostatic hyperplasia (BPH); however, recent clinical trials have questioned their efficacy, at least at standard doses (320 mg/d). To determine the effect of saw palmetto extract (Serenoa repens, from saw palmetto berries) at up to 3 times the standard dose on lower urinary tract symptoms attributed to BPH. A double-blind, multicenter, placebo-controlled randomized trial at 11 North American clinical sites conducted between June 5, 2008, and October 10, 2010, of 369 men aged 45 years or older, with a peak urinary flow rate of at least 4 mL/s, an American Urological Association Symptom Index (AUASI) score of between 8 and 24 at 2 screening visits, and no exclusions. One, 2, and then 3 doses (320 mg/d) of saw palmetto extract or placebo, with dose increases at 24 and 48 weeks. Difference in AUASI score between baseline and 72 weeks. Secondary outcomes included measures of urinary bother, nocturia, peak uroflow, postvoid residual volume, prostate-specific antigen level, participants' global assessments, and indices of sexual function, continence, sleep quality, and prostatitis symptoms. Between baseline and 72 weeks, mean AUASI scores decreased from 14.42 to 12.22 points (-2.20 points; 95% CI, -3.04 to -1.36) [corrected]with saw palmetto extract and from 14.69 to 11.70 points (-2.99 points; 95% CI, -3.81 to -2.17) with placebo. The group mean difference in AUASI score change from baseline to 72 weeks between the saw palmetto extract and placebo groups was 0.79 points favoring placebo (upper bound of the 1-sided 95% CI most favorable to saw palmetto extract was 1.77 points, 1-sided P = .91). Saw palmetto extract was no more effective than placebo for any secondary outcome. No clearly attributable adverse effects were identified. Increasing doses of a saw palmetto fruit extract did not reduce lower urinary tract symptoms more than placebo. clinicaltrials

Children with urinary tract disorders managed by teams, or individual pediatricians, urologists, nephrologists, gastroenterologists, neurologists, psychologists, and nurses at some point move from child-centered to adult-centered health systems. The actual physical change is referred to as the transfer whilst the process preceding this move constitutes transition of care. Our aims are twofold: to identify management and health-service problems related to children with congenital or acquired urological conditions who advance into adulthood and the clinical implications this has for long-term health and specialist care; and, to understand the issues facing both pediatric and adult-care clinicians and to develop a systems-approach model that meets the needs of young adults, their families and the clinicians working within adult services. Information was gleaned from presentations at an International Children's Continence Society meeting with collaboration from the International Continence Society, that discussed problems of transfer and transitioning such children. Several specialists attending this conference finalized this document identifying issues and highlighting ways to ease this transition and transfer of care for both patients and practitioners. The consensus was, urological patients with congenital or other lifelong care needs, are now entering adulthood in larger numbers than previously, necessitating new planning processes for tailored transfer of management. Adult teams must become familiar with new clinical problems in multiple organ systems and anticipate issues provoked by adolescence and physical growth. During this period of transitional care the clinician or team assists young patients to build attitudes, skills and understanding of processes needed to maximize function of their urinary tract-thus taking responsibility for their own healthcare needs. Preparation must also address, negotiating adult health care systems, psychosocial, educational or

Background Data describing urinary health in elderly, community-dwelling prostate cancer (PCa) survivors are limited. Objective To elucidate the prevalence of lower urinary tract symptoms, urinary bother, and incontinence in elderly PCa survivors compared with peers without PCa. Design, setting, and participants A cross-sectional analysis of 5990 participants in the Osteoporotic Fractures in Men Research Group, a cohort study of community-dwelling men ≥65 yr. Outcome measurements and statistical analysis We characterized urinary health using self-reported urinary incontinence and the American Urological Association Symptom Index (AUA-SI). We compared urinary health measures according to type of PCa treatment in men with PCa and men without PCa using multivariate log-binomial regression to generate prevalence ratios (PRs). Results and limitations At baseline, 706 men (12%) reported a history of PCa, with a median time since diagnosis of 6.3 yr. Of these men, 426 (60%) reported urinary incontinence. In adjusted analyses, observation (PR: 1.92; 95% confidence interval [CI], 1.15–3.21; p = 0.01), surgery (PR: 4.68; 95% CI, 4.11–5.32; p incontinence. Daily incontinence risk increased with time since diagnosis independently of age. Observation (PR: 1.33; 95% CI, 1.00–1.78; p = 0.05), surgery (PR: 1.25; 95% CI, 1.10–1.42; p = 0.0008), and ADT (PR: 1.50; 95% CI, 1.26–1.79; p urinary incontinence, which rose with increasing survivorship duration. Observation, surgery, and ADT were each associated with increased urinary bother. These data suggest a substantially greater burden of urinary health problems among elderly PCa survivors than previously recognized. PMID:23587870

Quality audit--a review of the literature concerning delivery of continence care.

Science.gov (United States)

Swaffield, J

1995-09-01

This paper outlines the role of quality audit within the framework of quality assurance, presenting the concurrent and retrospective approaches available. The literature survey provides a review of the limited audit tools available and their application to continence services and care delivery, as well as attempts to produce tools from national and local standard setting. Audit is part of a process; it can involve staff, patients and their relatives and the team of professionals providing care, as well as focusing on organizational and management levels. In an era of market delivery of services there is a need to justify why audit is important to continence advisors and managers. Effectiveness, efficiency and economics may drive the National Health Service, but quality assurance, which includes standards and audit tools, offers the means to ensure the quality of continence services and care to patients and auditing is also required in the purchaser/provider contracts for patient services. An overview and progress to date of published and other a projects in auditing continence care and service is presented. By outlining and highlighting the audit of continence service delivery and care as a basis on which to build quality assurance programmes, it is hoped that this knowledge will be shared through the setting up of a central auditing clearing project.

Incontinence is highly prevalent in the elderly population, especially in nursing home residents with dementia. It is a distressing and costly health problem that affects not only the patients but also the caregivers. Effective continence management is required to provide quality care, and to eliminate high labor costs and annoyances to the caregivers resulting from episodes of incontinence. This paper presents the design, development, and preliminary deployment of a smart wireless continence management system for dementia-impaired elderly or patients in institutional care settings such as nursing homes and hospitals. Specifically, the mote wireless platform was used to support the deployment of potentially large quantities of wetness sensors with wider coverage and with dramatically less complexity and cost. It consists of an intelligent signal relay mechanism so that the residents are free to move about in the nursing home or hospital and allows personalized continence management service. Preliminary results from a trial in a local nursing home are promising and can significantly improve the quality of care for patients.

UTI is an infection that occurs in the urinary tract due to the proliferation of a microorganism. Female is fourteen times more vulnerable to UTI than male, because their urethra is shorter. Bladder epithelium is coated with a thin layer of glycosaminoglycans which act as a non-specific anti-adherence factor and nonspecific defense mechanisms against infection and can be found in the urine. An analytic study with cross sectional approach was conducted in 46 patients (23 with UTI and 23 non UTI) from June 2016 to determine differences in levels of urinary glycosaminoglycans between two groups. Urine samples were taken and tested for UTI and non UTI strips test. Laboratory examination of urine GAGs levels using ELISA kit for Human Glycosaminoglycans, then tabulated and analyzed using SPSS. The result showed no significant differences in the characteristics of women between two groups. There are significant differences in the mean levels of urinary GAGs in women with UTI compared with Non-UTI (69.74 ± 21.34; 21.39 ± 2.61 mg/l; p UTI incidence, with low odds ratio values and no significant difference in the mean of urinary glicosaminoglycans level based on sexual status.

Urethral Closure Pressure at Stress: A Predictive Measure for the Diagnosis and Severity of Urinary Incontinence in Women

Directory of Open Access Journals (Sweden)

Anne-Cécile Pizzoferrato

2017-06-01

Full Text Available Purpose Maintaining urinary continence at stress requires a competent urethral sphincter and good suburethral support. Sphincter competence is estimated by measuring the maximal urethral closure pressure at rest. We aimed to study the value of a new urodynamic measure, the urethral closure pressure at stress (s-UCP, in the diagnosis and severity of female stress urinary incontinence (SUI. Methods A total of 400 women without neurological disorders were included in this observational study. SUI was diagnosed using the International Continence Society definition, and severity was assessed using a validated French questionnaire, the Mesure du Handicap Urinaire. The perineal examination consisted of rating the strength of the levator ani muscle (0–5 and an assessment of bladder neck mobility using point Aa (cm. The urodynamic parameters were maximal urethral closure pressure at rest, s-UCP, Valsalva leak point pressure (cm H2O, and pressure transmission ratio (%. Results Of the women, 358 (89.5% were diagnosed with SUI. The risk of SUI significantly increased as s-UCP decreased (odds ratio [OR], 0.92; 95% confidence interval, 0.88–0.98. The discriminative value of the measure was good for the diagnosis of SUI (area under curve>0.80. s-UCP values less than or equal to 20 cm H2O had a sensitivity of 73.1% and a specificity of 93.0% for predicting SUI. The association between s-UCP and SUI severity was also significant. Conclusions s-UCP is the most discriminative measure that has been identified for the diagnosis of SUI. It is strongly inversely correlated with the severity of SUI. It appears to be a specific SUI biomarker reflecting both urethral sphincter competence and urethral support.

[Urinary incontinence and pregnancy].

Science.gov (United States)

Deffieux, X

2009-12-01

The goal of the current study was to systematically review the literature concerning urinary incontinence and pregnancy, in order to develop recommendations for clinical practice. The prevalence of urinary stress incontinence and overactive bladder symptoms increase with gestational age during pregnancy (from the first to the third trimester), and decrease during the third months following delivery. Obstetrics factors (position during delivery, length of the second part of the labour, forceps, episiotomy, epidural or pudendal anaesthesia) do not modify the risk of post-partum or long term urinary incontinence. At short term follow-up, caesarean delivery is associated with a lower rate of post-partum urinary incontinence. At long term follow-up, data are lacking. Non elective caesarean section is not associated with a decrease in the rate of post-partum or long-term urinary incontinence. Elective caesarean section and systematic episiotomy are not recommended methods for the prevention of post-partum urinary incontinence (grade B), even in "high risk" women. Pelvic floor muscle therapy is the first line treatment for prenatal or post-partum urinary incontinence (grade A). Copyright © 2009 Elsevier Masson SAS. All rights reserved.

Transperineal ultrasonography in stress urinary incontinence: The significance of urethral rotation angles.

Science.gov (United States)

Al-Saadi, Wasan Ismail

2016-03-01

To assess, using transperineal ultrasonography (TPUS), the numerical value of the rotation of the bladder neck [represented by the difference in the anterior (α angle) and posterior urethral angles (β angle)] at rest and straining, in continent women and women with stress urinary incontinence (SUI), to ascertain if there are significant differences in the angles of rotation (Rα and Rβ) between the groups. In all, 30 women with SUI (SUI group) and 30 continent women (control group) were included. TPUS was performed at rest and straining (Valsalva manoeuver), and the threshold value for the urethral angles (α and β angles) for each group were estimated. The degree of rotation for each angle was calculated and was considered as the angle of rotation. Both the α and β angles were significantly different between the groups at rest and straining, and there was a significant difference in the mean increment in the value of each angle. Higher values of increment (higher rotation angles) were reported in the SUI group for both the α and β angles compared with those of the control group [mean (SD) Rα SUI group 19.43 (12.76) vs controls 10.53 (2.98) °; Rβ SUI group 28.30 (12.96) vs controls 16.33 (10.8) °; P < 0.001]. Urethral rotation angles may assist in the assessment and diagnosis of patients with SUI, which may in turn reduce the need for more sophisticated urodynamic studies.

Gomes, Marcelo da Silva; Montone, Rosalinda Carmela; Weber, Rolf Roland

1999-01-01

The Antarctic Continent is relatively free from human activities but it already comes presenting low levels of environmental contamination for anthropogenic sources. The anthropogenic contamination can be taken mainly to the continent through different manners for the marine and atmospheric currents. This work has as objective to analyze samples of sediments from Antarctic Continent in the area of Almirantado Bay, where the Brazilian Station of Resource Comandante Ferraz is located. The concentrations of ten metallic elements (Ni, Cu, Zn, Cd, Sn, Pb, U, Al, Fe and Li) were analyzed in twelve collection sites along the whole Bay. AAS and HR-ICPMS accomplished the analyses of those metallic elements. It was verified in the obtained results that a variation does not exist in the concentrations obtained among the collection sites, indicating a homogeneity in the area and there is no evidence of polluting source, at least at those obtained concentration levels.

To reduce short-term complications of radical cystectomy (RC) and intestinal urinary diversion with vescica ileale Padovana (VIP) neobladder, we described and assessed an enhanced recovery protocol (ERP) in a series of consecutive patients. An ERP was introduced focusing on reduced bowel preparation, standardized feeding and analgesic regimens. We analyzed the outcomes with all patients consecutively undergoing RC and VIP neobladder who met the following inclusion criteria: American Society of Anesthesiologists score Short Form criteria; absence of inflammatory bowel diseases. Thirty-one consecutive patients were recruited to undergo our ERP. Mean age of patients was 62.16 years. No patients died due to surgical complications. Nine of 31 patients experienced complications (29.03%), none requiring surgical intervention. According to Clavien grading, all complications were grade <2. The application of our ERP to our patients undergoing RC and VIP neobladder contributed to reduce postoperative morbidity. Copyright © 2013 S. Karger AG, Basel.

2013-09-01

Full Text Available Objectives: To analyze the short and long term results of tapes of different materials used to treat stress urinary incontinence (SUI. A secondary objective was to evaluate the ability to adjust the tape after implantation. Materials and methods: Retrospective chart review of 355 patients with SUI operated between March 2003 and October 2011. Eight different types of transobturator tapes were used: Gynecare TVT-O®, Monarc®, SAFYRE®, Contasure KIM®, I-Stop®, DynaMesh®, Aris® Bandellete and Swing-band®. Results and complications were recorded. Results: The mean age at operation was 61 years. Correction of SUI was achieved in 87.88% of cases. The best results were obtained with Contasure KIM® (98.26 % continence. The tape was well tolerated and was elastic enough to be able to be adjusted 48-72 hours after implantation without deformation. Slings with macropores and over lock stiches on the superior and inferior borders presented the lower rates of postoperative urinary retention, pain, perior postoperative bleeding and urinary tract infections. Conclusions: Transobturator tension free tapes require a short operation time and have a low complication rate. The possibility of adjustment in the early postoperative period increases the success rate and reduces complications. Knotless meshes with macropores and over lock stiches appear to be better balanced, are quite resistant to stretching and deformation when readjusted after implantation and present a low infection rate.

Diversity and disparity of sparassodonts (Metatheria) reveal non-analogue nature of ancient South American mammalian carnivore guilds

Dolgushina, Tatiana; Wesley, Gina

2018-01-01

This study investigates whether terrestrial mammalian carnivore guilds of ancient South America, which developed in relative isolation, were similar to those of other continents. We do so through analyses of clade diversification, ecomorphology and guild structure in the Sparassodonta, metatherians that were the predominant mammalian carnivores of pre-Pleistocene South America. Body mass and 16 characters of the dentition are used to quantify morphological diversity (disparity) in sparassodonts and to compare them to extant marsupial and placental carnivores and extinct North American carnivoramorphans. We also compare trophic diversity of the Early Miocene terrestrial carnivore guild of Santa Cruz, Argentina to that of 14 modern and fossil guilds from other continents. We find that sparassodonts had comparatively low ecomorphological disparity throughout their history and that South American carnivore palaeoguilds, as represented by that of Santa Cruz, Argentina, were unlike modern or fossil carnivore guilds of other continents in their lack of mesocarnivores and hypocarnivores. Our results add to a growing body of evidence highlighting non-analogue aspects of extinct South American mammals and illustrate the dramatic effects that historical contingency can have on the evolution of mammalian palaeocommunities.

Heckenberg, Gayle

2008-06-01

Background  Continence Management within residential aged care is an every day component of care that requires assessment, implementation of strategies, resource allocation and evaluation. At times the management of incontinence of aged residents can be challenging and unsuccessful. The project chosen through the Clinical Fellowship program was Continence Management with the aim of raising awareness of best practice to assist in improving and providing person-centred resident care. Aims/objectives •  Review the literature on best practice management of incontinence •  Evaluate current practice in continence management for elderly residents within residential aged care services •  Improve adherence to best practice strategies of care for incontinence •  Raise awareness within the nursing home of the best practice management of incontinence •  Promote appropriate and effective use of resources for continence management •  Deliver individualised person-centred care to residents. •  Ensure best practice in continence management Methods  The Joanna Briggs Institute (JBI) Practical Application of Clinical Evidence System clinical audit tool was utilised to measure current practice against best practice. The results identify gaps that require improvement. The Getting Research into Practice process then allowed analysis of the level of compliance with each of the audit criteria, which would identify any barriers in implementing a selected course of action and aim to improve compliance. The project team was consulted with additional stakeholder consultation to form an action plan and implement strategies to improve practice. Results  Although 100% compliance with all audit criteria in audit 1 and 2 was not achieved, there was improvement in the criteria concerning the documented fluid intake for residents. Further strategies have been identified and implemented and this continues to be a 'work in progress'. Staff now have an acute awareness

To create an International Urinary Tract Imaging Basic Spinal Cord Injury (SCI) Data Set within the framework of the International SCI Data Sets. An international working group. The draft of the Data Set was developed by a working group comprising members appointed by the Neurourology Committee of the International Continence Society, the European Association of Urology, the American Spinal Injury Association (ASIA), the International Spinal Cord Society (ISCoS) and a representative of the Executive Committee of the International SCI Standards and Data Sets. The final version of the Data Set was developed after review and comments by members of the Executive Committee of the International SCI Standards and Data Sets, the ISCoS Scientific Committee, ASIA Board, relevant and interested international organizations and societies (around 40), individual persons with specific expertise and the ISCoS Council. Endorsement of the Data Sets by relevant organizations and societies will be obtained. To make the Data Set uniform, each variable and each response category within each variable have been specifically defined in a way that is designed to promote the collection and reporting of comparable minimal data. The variables included in the International Urinary Tract Imaging Basic SCI Data Set are the results obtained using the following investigations: intravenous pyelography or computer tomography urogram or ultrasound, X-ray, renography, clearance, cystogram, voiding cystogram or micturition cystourogram or videourodynamics. The complete instructions for data collection and the data sheet itself are freely available on the websites of both ISCoS (http://www.iscos.org.uk) and ASIA (http://www.asia-spinalinjury.org).

Groundwater systems of the Indian Sub-Continent

Abhijit Mukherjee

2015-09-01

Full Text Available The Indian Sub-Continent is one of the most densely populated regions of the world, hosting ∼23% of the global population within only ∼3% of the world's land area. It encompasses some of the world's largest fluvial systems in the world (River Brahmaputra, Ganges and Indus Basins, which hosts some of the highest yielding aquifers in the world. The distribution of usable groundwater in the region varies considerably and the continued availability of safe water from many of these aquifers (e.g. Bengal Basin is constrained by the presence of natural contaminants. Further, the trans-boundary nature of the aquifers in the Indian Sub-Continent makes groundwater resource a potentially politically sensitive issue, particularly since this region is the largest user of groundwater resources in the world. Indeed, there is considerable concern regarding dwindling well yield and declining groundwater levels, even for the highly productive aquifers. Though irrigation already accounts for >85% of the total ground water extraction of the region, there is a mounting pressure on aquifers for food security of the region. Highly variable precipitation, hydrogeological conditions and predicted, impending climate change effects provide substantial challenges to groundwater management. The observed presence of natural groundwater contaminants together with the growing demand for irrigated food production and predicted climate change further complicate the development of strategies for using groundwater resources sustainably. We provide an introduction and overview of 11 articles, collated in this special issue, which describe the current condition of vulnerable groundwater resources across the Indian Sub-Continent.

Although lower urinary tract symptoms have been associated with falls, few studies have been undertaken to understand this relationship in vulnerable community dwelling older adults. The purpose of this study was to describe the relationship over time of falls risk and lower urinary tract symptoms among community based older women receiving home support services. A prospective cohort study which took place in an urban setting in western Canada. Participants were 100 older women receiving home care or residing in assisted living with home support services and were followed for six months. Demographic characteristics were collected at baseline, with the Timed Up and Go (TUG), International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms (ICIQ-FLUTS), and self-report of falls collected at baseline, 3 and 6 months. Descriptive statistics were used to summarize demographic data. Differences between the three visits were analyzed using the Friedman test with post hoc analysis and associations between variables by the Spearman Rank-Order Correlation Coefficient. One hundred women initially enrolled; 88 and 75 remained at three months and six months. Mean age = 84.3 years; 91% reported at least one urinary symptom at baseline and 35% reported falling in the six months prior to enrollment; 15.9% reported falling between the baseline and three months and 14.6% between three and six months. Mean TUG scores at each time point indicated falls risk (27.21, 29.18 and 27.76 seconds). Significant correlations between TUG and ICIQ-FLUTS (r = 0.33, p falls risk in this group of vulnerable community dwelling older women at baseline and three months has potential clinical relevance. Lack of correlation at six months may be due loss of less robust participants, illuminating the difficulty in following frailer groups over time. Further studies are needed to understand the contribution of urinary symptoms to falls risk, and clinicians should

2012-01-01

Full Text Available Female urethral diverticulum is a rare entity with diverse spectrum of clinical manifestations. It is a very rare cause of bladder outlet obstruction and should be considered as a differential diagnosis in females presenting with acute urinary retention associated with a vaginal mass. Strong clinical suspicion combined with thorough physical examination and focused radiological investigations are vital for its diagnosis. Herein we report a case of giant urethral diverticulum presenting with acute urinary retention in a young female. It was managed by excision and urethral closure, and is the largest urethral diverticulum reported till date in the literature.

What do Cochrane systematic reviews say about non-surgical interventions for urinary incontinence in women?

Directory of Open Access Journals (Sweden)

Anderson Adriano Leal Freitas da Costa

Full Text Available ABSTRACT BACKGROUND: Urinary incontinence is a highly prevalent condition that impacts self-esteem and overall quality of life. Many non-surgical treatment options are available, ranging from pharmacological approaches to pelvic exercises. We aimed to summarize the available evidence regarding these non-surgical interventions. DESIGN AND SETTING: Review of systematic reviews, conducted in the Discipline of Evidence-Based Medicine, Escola Paulista de Medicina, Universidade Federal de São Paulo (EPM-UNIFESP. METHODS: A sensitive search was conducted to identify all Cochrane systematic reviews that fulfilled the inclusion criteria. Titles and abstracts were screened by two authors. RESULTS: We included 20 Cochrane systematic reviews: 4 assessing methods of vesical training, 3 evaluating pharmacological interventions, 4 studying pelvic floor muscle training approaches and 9 aimed at other alternatives (such as urethral injections, weighted vaginal cone use, acupuncture, biostimulation and radiofrequency therapy. The reviews found that the evidence regarding the benefits of these diverse interventions ranged in quality from low to high. CONCLUSIONS: This review included 20 Cochrane systematic reviews that provided evidence (of diverse quality for non-pharmacological interventions for patients with urinary incontinence. Moderate to high quality of evidence was found favoring the use of pelvic floor muscle training among women with urinary incontinence. To establish solid conclusions for all the other comparisons, further studies of good methodological quality are needed.

Determine correlation between complications and stage of the disease and their impact on quality of life in patients with different types of ileal urinary derivation after radical cystectomy, and upon estimation of acquired results, to suggest the most acceptable type of urinary diversion. In five year period a prospective clinical study was performed on 106 patients, to whom a radical cystectomy was performed due to bladder cancer. Patients were divided into two groups, 66 patients with ileal conduit derivation and 40 patients with orthotopic derivation, whereby in each group a comparison between reflux and anti-reflux technique of orthotopic bladder was made. All patients from both groups filled the Sickness Impact Profile score six months after the operation. All patients had CT urography or Intravenous urography performed, as well as standard laboratory, vitamin B12 blood values, in order to evaluate early (ileus or subileus, wound dehiscence, bladder fistula, rupture of orthotopic bladder, urine extravazation) and late complications (VUR, urethral stricture, ureter stenosis, metabolic acidosis, mineral dis-balance, hypovitaminosis of vitamin B12, increased resorption of bone calcium, urinary infection, kidney damage, relapse of primary disease), so as disease stage and it's impact on quality of life. From gained results we observe that each category of SIP score correlates with different rate of correlation with the type of operation, group, T, N, and R grade, except work category. Average value of SIP score rises depending on the type of operation and T stage. It is notable that there is no difference in T1 stage, no matter the type of operation. So the average value of SIP score in T1 stage for conduit was 20.3, for Abol-Enein and Ghoneim 17.25 and Hautmann 18.75 respectively. Average value of SIP score in T2 stage for conduit was 31, for Abol-Enein and Ghoneim 19.1 and Hautmann 17.8. Average value of SIP score in T3 stage for conduit was 38.03, for Abol

Catheter-associated urinary tract infections account for 30% of healthcare-associated infections. To date, few studies have addressed pediatric catheter-associated urinary tract infection in PICUs. The aim of our study was to assess the risk of catheter-associated urinary tract infection in relation to the duration of catheterization in the PICU. Retrospective cohort study. PICU at a tertiary children's hospital. Our study was conducted between April 2012 and June 2015 at Tokyo Metropolitan Children's Medical Center in Japan. Children in the PICU with an urethral catheter were included. Catheter-associated urinary tract infection cases were defined according to the National Healthcare Safety Network criteria. The patients' demographic data and isolated organisms were reviewed. Duration of catheterization and the catheter-associated urinary tract infection occurrence rate were analyzed. None. Among 1,890 catheterizations, 23 catheter-associated urinary tract infection cases were identified. The overall occurrence rate was 2.35/1,000 catheter-days. Among the patients with catheter-associated urinary tract infection, 13 were boys. The median age was 11 months (interquartile range, 7-35 mo), and the median duration of catheterization was 7 days (interquartile range, 5-12 d). The isolated bacteria were Escherichia coli (26.5%), Enterococcus faecalis (17.6%), and Klebsiella pneumoniae (11.8%). Two species were isolated in each of 11 cases (47.8%). Each additional day of catheterization increased the risk of catheter-associated urinary tract infection (odds ratio, 1.06; 95% CI, 1.02-1.10, and odds ratio adjusted for contact precaution status and surgical procedures was 1.05; 95% CI, 1.01-1.09). Longer duration of catheterization increased the risk of catheter-associated urinary tract infection by 5% each day at the PICU. Prompt removal of the urethral catheter is strongly recommended whenever feasible.

Full Text Available BackgroundUrinary continence and erectile function (EF are best preserved when meticulous dissection of prostate and nerve sparing technique are used during radical prostatectomy (RP. However, extent of lymph node dissection (LND may also adversely affect functional results.ObjectiveTo determine whether performing a super-extended LND (seLND has a significant effect on recovery of urinary continence and EF after RP.Design, setting, and participantsAll patients who underwent RP from January 2007 until December 2013 were handed questionnaires assessing continence and EF. All patients in whom at least an extended LND (eLND was performed were selected. This search yielded 526 patients. 172 of these patients had filed out 2 or more questionnaires and were included in our analysis.Outcome measurements and statistical analysisAll questionnaires were reviewed. We used Kaplan–Meier analyses and multivariate Cox analysis to assess the difference in recovery of continence and EF over time for eLND/seLND. Primary endpoints were full recovery of continence (no loss of urine and full recovery of EF (successful intercourse possible. Patients who did not reach the endpoint when the last questionnaire was filled out were censored at that time. Median follow-up was 12.43 months for continence, and 18.97 months for EF.Results and limitationsPatients undergoing seLND have a lower chance of regaining both urinary continence [hazard ratio (HR 0.59, 95% CI 0.39–0.90, p = 0.026] and EF (HR 0.28, 95% CI 0.13–0.57, p = 0.009. Age at surgery had a significant influence on both continence and EF in multivariate analysis. Major limitation of the study was that no formal preoperative assessment of continence and potency was done.ConclusionExtending the LND template beyond the eLND template may cause at least a significant delay in recovery of urinary continence and leads to less recovery of EF.

Based on previous findings, from a worldwide study, classified the shapes of human hair into 8 major types, from straight to highly curly. This clearly extended the usual classification of hair into African, Asian or Caucasian types. However, determinations of hair growth parameters and hair density were excluded from such studies. To measure and compare the hair growth profiles of young adults without alopecia living in the five continents. 2249 young adults (18-35 years, females and males) without alopecia, originating from 24 various human ethnic groups were included in the study. Total hair density, telogen percentage and growth rate on three different scalp areas were measured, using non-invasive validated techniques. Natural hair colour level, curliness and hair diameter were additionally recorded, when practically possible. Diversity in hair growth parameters among the entire cohort was a key finding, with differences linked to scalp area, gender and geographic origin. Statistical approaches depicted African hair as having lower density and a slower growth rate. Asian hair showed a thicker diameter, with faster growth. Caucasian hair showed a high total hair density. On the one hand, this inter-continental study of hair growth parameters provides initial valuable base-line data on hair in young adults without alopecia, and on the other hand, further extends our knowledge of this unique human appendage, with some mosaic features, observed worldwide.

Purpose: Urinary incontinence (UI) affects as many as 50% of women aged 60 years and older, but UI pathophysiology, specifically in elderly women, remains unclear. A better understanding of morphometric differences between continent and urinary incontinent elderly women is needed to improve the effectiveness of conservative treatment approaches. We hypothesized that morphometric differences in the pelvic floor muscles (PFM) among elderly women with and without UI could be observed using three- and four-dimensional (3D/4D) transperineal ultrasound (TPU) imaging. Method: A total of 40 elderly women (20 women with and 20 women without UI), with a mean age of 67.10 (SD 4.94) years, participated in the study. This was a case-control study in which TPU images were taken under three conditions: rest, maximal voluntary contraction (MVC), and Valsalva. Independent t -tests were conducted to compare measurements between the groups. Results: The study revealed statistically significant differences between the groups. At rest, the levator hiatal area and transverse diameter were bigger, and the PFM position was lower in the incontinent group. During MVC, all axial plane parameters were bigger in the incontinent group. In the sagittal plane, PFM position was again lower in the incontinent group. During Valsalva, the anorectal angle was wider in the women with incontinence. Conclusion: PFM morphometric differences were present and were observed using 3D/4D TPU imaging in elderly women with and without UI.

Vegetation is sparsely distributed over Antarctica's ice-free ground, and distinct plant communities are present in each of the continent's 15 recently identified Antarctic Conservation Biogeographic Regions (ACBRs). With rapidly increasing human activity in Antarctica, terrestrial plant communities are at risk of damage or destruction by trampling, overland transport, and infrastructure construction and from the impacts of anthropogenically introduced species, as well as uncontrollable pressures such as fur seal (Arctocephalus gazella) activity and climate change. Under the Protocol on Environmental Protection to the Antarctic Treaty, the conservation of plant communities can be enacted and facilitated through the designation of Antarctic Specially Protected Areas (ASPAs). We examined the distribution within the 15 ACBRs of the 33 ASPAs whose explicit purpose includes protecting macroscopic terrestrial flora. We completed the first survey using normalized difference vegetation index (NDVI) satellite remote sensing to provide baseline data on the extent of vegetation cover in all ASPAs designated for plant protection in Antarctica. Large omissions in the protection of Antarctic botanical diversity were found. There was no protection of plant communities in 6 ACBRs, and in another 6, area was included in an ASPA that protected vegetation. Protected vegetation cover within the 33 ASPAs totaled 16.1 km(2) for the entire Antarctic continent; over half was within a single protected area. Over 96% of the protected vegetation was contained in 2 ACBRs, which together contributed only 7.8% of the continent's ice-free ground. We conclude that Antarctic botanical diversity is clearly inadequately protected and call for systematic designation of ASPAs protecting plant communities by the Antarctic Treaty Consultative Parties, the members of the governing body of the continent. © 2015 The Authors.

To assess the renal effects of low-level exposure to cadmium due to smoking we examined blood and urinary levels of cadmium and urinary excretions of N-acetyl-[beta]-D-glucosaminidase (NAG), [beta][sub 2]-microglobulin (BMG) and metallothionein in 94 male workers aged 18-55 years. Both blood and urinary cadmium levels indicated excess exposure to cadmium caused by smoking. The urinary cadmium concentration ranged between 0.1 and 5.0 [mu]g/g creatinine and increased significantly with age in the smokers. Neither urinary NAG nor BMG was increased in the smokers compared from non-smokers. A positive relationship between urinary cadmium and metallothionein was obtained not only in the smokers but also in the non-smokers. Furthermore, in the smokers urinary cadmium and metallothionein was positively related with urinary NAG. Since NAG in urine mostly originates from tubular cells by lysosomal exocytosis, the results may reflect an early cadmium effect on the lysosomal functions. Inhibitory effect of cadmium on the lysosomal degradation activities was discussed as a possible explanation of the positive relationship of urinary cadmium and metallothionein to urinary NAG.

To explore the impact of the secondary school environment on young people with continence problems. In-depth qualitative semi-structured interviews. We interviewed 20 young people aged 11-19 years (11 female and nine male) with continence problems (daytime wetting, bedwetting, and/or soiling). Interviews were conducted by Skype (n = 11) and telephone (n = 9). Transcripts were analysed using inductive thematic analysis. We generated five main themes: (1) Boundaries of disclosure: friends and teachers; (2) Social consequences of avoidance and deceit; (3) Strict and oblivious gatekeepers; (4) Intimate actions in public spaces; and (5) Interrupted learning. Disclosure of continence problems at school to both friends and teachers was rare, due to the perceived stigma and fears of bullying and social isolation. The lack of disclosure to teachers and other school staff, such as pastoral care staff, creates challenges in how best to support these young people. Young people with continence problems require unrestricted access to private and adequate toilet facilities during the school day. There is a need for inclusive toilet access policies and improved toilet standards in schools. Addressing the challenges faced by young people with continence problems at school could help to remove the barriers to successful self-management of their symptoms. It is particularly concerning that young people with continence problems are at higher risk of academic underachievement. Increased support at school is needed to enable young people with continence problems to achieve their academic potential. Statement of Contribution What is already known on this subject? Continence problems are among the most common paediatric health problems Self-management of continence problems requires a structured schedule of fluid intake and bladder emptying Inadequate toilet facilities and restricted access make it difficult for young people to manage their incontinence What does this study add

Support of the mid-urethra is thought to be an essential element of urinary continence in the female. Our aim was to image the behavior of the mid-urethra in healthy volunteers and in stress urinary incontinence (SUI) patients by dynamic magnetic resonance imaging (MRI). Prospective study. Gynecology outpatient clinic association with Department of Radiology in University Hospital of Kuopio, Finland. Fifteen healthy volunteers and 40 SUI women underwent dynamic MRI at rest, during pelvic floor muscle contraction, coughing and voiding with a bladder volume of 200 ml. Our aim was to determine the precise location and movement of the mid-urethra during these activities. The co-ordinate location and movement of the mid-urethra. Continent volunteers can elevate their mid-urethra significantly higher than incontinent women. Moreover, the mid-urethra of incontinent women rotated significantly more dorsocaudally during straining and coughing than in continent women. Elevation of the mid-urethra was more marked in continent compared to urinary incontinent women on pelvic floor muscle contraction suggesting sufficient support of the urethra. Downward movement of the mid-urethra was more significant in stress incontinent women than in continent volunteers.

Mantle temperature under drifting deformable continents during the supercontinent cycle

Yoshida, Masaki

2013-04-01

The thermal heterogeneity of the Earth's mantle under the drifting continents during a supercontinent cycle is a controversial issue in earth science. Here, a series of numerical simulations of mantle convection are performed in 3D spherical-shell geometry, incorporating drifting deformable continents and self-consistent plate tectonics, to evaluate the subcontinental mantle temperature during a supercontinent cycle. Results show that the laterally averaged temperature anomaly of the subcontinental mantle remains within several tens of degrees (±50 °C) throughout the simulation time. Even after the formation of the supercontinent and the development of subcontinental plumes due to the subduction of the oceanic plates, the laterally averaged temperature anomaly of the deep mantle under the continent is within +10 °C. This implies that there is no substantial temperature difference between the subcontinental and suboceanic mantles during a supercontinent cycle. The temperature anomaly immediately beneath the supercontinent is generally positive owing to the thermal insulation effect and the active upwelling plumes from the core-mantle boundary. In the present simulation, the formation of a supercontinent causes the laterally averaged subcontinental temperature to increase by a maximum of 50 °C, which would produce sufficient tensional force to break up the supercontinent. The periodic assembly and dispersal of continental fragments, referred to as the supercontinent cycle, bear close relation to the evolution of mantle convection and plate tectonics. Supercontinent formation involves complex processes of introversion, extroversion or a combination of these in uniting dispersed continental fragments, as against the simple opening and closing of individual oceans envisaged in Wilson cycle. In the present study, I evaluate supercontinent processes in a realistic mantle convection regime. Results show that the assembly of supercontinents is accompanied by a

Phylogeography of the Microcoleus vaginatus (Cyanobacteria from three continents--a spatial and temporal characterization.

Directory of Open Access Journals (Sweden)

Full Text Available It has long been assumed that cyanobacteria have, as with other free-living microorganisms, a ubiquitous occurrence. Neither the geographical dispersal barriers nor allopatric speciation has been taken into account. We endeavoured to examine the spatial and temporal patterns of global distribution within populations of the cyanobacterium Microcoleus vaginatus, originated from three continents, and to evaluate the role of dispersal barriers in the evolution of free-living cyanobacteria. Complex phylogeographical approach was applied to assess the dispersal and evolutionary patterns in the cyanobacterium Microcoleus vaginatus (Oscillatoriales. We compared the 16S rRNA and 16S-23S ITS sequences of strains which had originated from three continents (North America, Europe, and Asia. The spatial distribution was investigated using a phylogenetic tree, network, as well as principal coordinate analysis (PCoA. A temporal characterization was inferred using molecular clocks, calibrated from fossil DNA. Data analysis revealed broad genetic diversity within M. vaginatus. Based on the phylogenetic tree, network, and PCoA analysis, the strains isolated in Europe were spatially separated from those which originated from Asia and North America. A chronogram showed a temporal limitation of dispersal barriers on the continental scale. Dispersal barriers and allopatric speciation had an important role in the evolution of M. vaginatus. However, these dispersal barriers did not have a permanent character; therefore, the genetic flow among populations on a continental scale was only temporarily present. Furthermore, M. vaginatus is a recently evolved species, which has been going through substantial evolutionary changes.

Diffusion-Weighted Magnetic Resonance Imaging of Urinary Epithelial Cancer with Upper Urinary Tract Obstruction: Preliminary Results

International Nuclear Information System (INIS)

Takeuchi, M.; Matsuzaki, K.; Kubo, H.; Nishitani, H.

2008-01-01

Background: Various malignant tumors of the body show high signal intensity on diffusion-weighted magnetic resonance imaging (DWI). In the genitourinary region, DWI is expected to have a role in detecting urinary epithelial cancer noninvasively. Purpose: To demonstrate the feasibility of DWI for the diagnosis of urinary epithelial cancer with upper urinary tract obstruction. Material and Methods: Twenty upper urinary tract cancers in 16 patients were evaluated by high-b-value DWI (b=800s/mm2). The signal intensity was visually evaluated, and the apparent diffusion coefficients (ADCs) were measured. Results: All urinary epithelial cancers showed high signal intensity on DWI. The ADC in cancerous lesions was 1.31±0.27 x 10 -3 mm 2 /s, which was significantly lower than that of the lumens of the ureter or renal pelvis (3.32±0.44 x 10 -3 mm 2 /s; P<0.001). Maximum intensity projection images of DWI in combination with static-fluid MR urography provided three-dimensional entire urinary tract imaging with the extension of tumors. Conclusion: DWI is useful in the tumor detection and in evaluating the tumor extension of urinary epithelial cancer in patients with upper urinary tract obstruction

Invasive species can displace natives, and thus identifying the traits that make aliens successful is crucial for predicting and preventing biodiversity loss. Pathogens may play an important role in the invasive process, facilitating colonization of their hosts in new continents and islands. According to the Novel Weapon Hypothesis, colonizers may out-compete local native species by bringing with them novel pathogens to which native species are not adapted. In contrast, the Enemy Release Hypothesis suggests that flourishing colonizers are successful because they have left their pathogens behind. To assess the role of avian malaria and related haemosporidian parasites in the global spread of a common invasive bird, we examined the prevalence and genetic diversity of haemosporidian parasites (order Haemosporida, genera Plasmodium and Haemoproteus) infecting house sparrows (Passer domesticus). We sampled house sparrows (N = 1820) from 58 locations on 6 continents. All the samples were tested using PCR-based methods; blood films from the PCR-positive birds were examined microscopically to identify parasite species. The results show that haemosporidian parasites in the house sparrows' native range are replaced by species from local host-generalist parasite fauna in the alien environments of North and South America. Furthermore, sparrows in colonized regions displayed a lower diversity and prevalence of parasite infections. Because the house sparrow lost its native parasites when colonizing the American continents, the release from these natural enemies may have facilitated its invasion in the last two centuries. Our findings therefore reject the Novel Weapon Hypothesis and are concordant with the Enemy Release Hypothesis.

2017-05-01

To review our experience in robot-assisted radical cystectomy, assessing the complications and oncological and functional results. From 2007 to 2014, we performed 67 robot-assisted radical cystectomies combined with lymphadenectomy in 61 cases. The operations were performed on 37 patients due to muscle-invasive tumours and on 30 due to high-risk nonmuscle-invasive tumours. Urinary diversion was conducted extracorporeally, using a Studer neobladder in 47 cases. The mean blood loss was 300mL. No case required conversion to open surgery. The median number of lymph nodes extracted was 16 (range 3-33). Pathology revealed 16 pT0, 15 pTis,-pT1-pTa and 44 muscle-invasive tumours, 8 pN+ and 1 with positive margins. The mean hospital stay was 9 days. With a median follow-up of 16 months, 9 (13%) patients were readmitted after the discharge, most for infections associated with the vesical catheter and other catheters. Forty patients (59.7%) presented complications (most were Clavien grade 1-2). There was recurrence during the follow-up in 4 cases (6%), and 4 (5.9%) patients died from cancer. Nineteen (28.3%) patients had complications after 30 days, most of which were urinary tract infections. Of the 47 patients with a neobladder, 45 (96%) had proper daytime continence and 42 (89%) had proper nighttime continence. Ninety percent and 64% of the patients with previously normal sexual function and reduced sexual function, respectively, were able to preserve sexual function with or without drug treatment. Robot-assisted radical cystectomy plus lymphadenectomy, with extracorporeal reconstruction of the urinary diversion, offers good oncological and functional results without increasing the number of complications.

The basic structures and organs contributing to continence in men are far less well investigated than in women. This concerns anatomical and functional aspects as well. Especially the cooperation of single components and the dynamic anchoring in the pelvic floor require further investigation. An improved anatomical-functional interpretation is needed to generate therapeutic concepts orientated at the physiology of the bladder neck.Therefore, the focus of anatomical investigations should be on the external sphincter which is the main muscle responsible for urethral closure as well as on the connective tissue, smooth muscular and neuronal structures in the pelvis. The smooth muscular structures involved are the internal sphincter, the inner parts of the external sphincter, the urethral longitudinal musculature, and parts of the centrum perinei and of the ventral suspension apparatus which fixes the position of the bladder neck and seems to be vital for continence and initiation of micturition. These new findings imply an integral concept for men as was developed for women. A first step in this regard would be a consistent and updated anatomical nomenclature.

Free-volume distributions of polymers by positron annihilation spectroscopy: further experiences in using CONTIN for continuous lifetime distributions

Thorough examinations of the CONTIN program were carried out by using the simulated positron lifetime spectra, to reveal the capability of CONTIN in the reconstruction of the positron lifetime distributions. It is shown that: 1. very high statistics is strongly desired by CONTIN to reproduce reliable lifetime distributions; 2. improving the time resolution of the measurement system, to the level of 0.030 ns full width at half maximum, does not significantly improve the resolving power of CONTIN; and 3. reducing the time width per channel is a practical way of improving the reconstruction of the lifetime probability density functions by CONTIN.

Full Text Available Hypertension is a complex disease explained with diverse factors including environmental factors and genetic factors. The objectives of this study were to determine the interaction effects between gene variants and 24 h estimated urinary sodium and potassium excretion and sodium-potassium excretion ratios on the risk of hypertension. A total of 8839 participants were included in the genome-wide association study (GWAS to find genetic factors associated with hypertension. Tanaka and Kawasaki formulas were applied to estimate 24 h urinary sodium and potassium excretion. A total of 4414 participants were included in interaction analyses to identify the interaction effects of gene variants according to 24 h estimated urinary factors on the risk of hypertension. CSK rs1378942 and CSK-MIR4513 rs3784789 were significantly modified by urinary sodium-potassium excretion ratio. In addition, MKLN rs1643270 with urinary potassium excretion, LOC101929750 rs7554672 with urinary sodium and potassium excretion, and TENM4 rs10466739 with urinary sodium-potassium excretion ratio showed significant interaction effects. The present study results indicated that the mutant alleles of CSK rs1378942 and CSK-MIR4513 rs3784789 had the strongest protective effects against hypertension in the middle group of 24 h estimated urinary sodium-potassium excretion ratio. Further studies are needed to replicate these analyses in other populations.

[Male Urinary Incontinence--a Taboo Issue].

2016-03-02

Male urinary incontinence is an underestimated and frequently not broached issue. The urinary incontinence is divided into stress-, urge incontinence and hybrid forms as well as overflow incontinence. The fact that there are increasingly more men over 60 means that the prevalence of the urinary incontinence is up to 40%, and urinary incontinence will increasingly gain importance in daily routine practice. Many investigations and therapies can be realized by the general practitioner. Already simple therapy approaches can lead to a considerable clinical improvement of male urinary incontinence. If the initial therapy fails or pathological results (i. e. microhaematuria, recurrent urinary tract infections, raised residual urine and so on) are found, the patient should be referred to a urologist.

Madagascar: Heads It's a Continent, Tails It's an Island

Science.gov (United States)

de Wit, Maarten J.

Neither geologists nor biologists have a definition that is capable of classifying Madagascar unambiguously as an island or a continent; nor can they incorporate Malagasy natural history into a single model rooted in Africa or Asia. Madagascar is a microcosm of the larger continents, with a rock record that spans more than 3000 million years (Ma), during which it has been united episodically with, and divorced from, Asian and African connections. This is reflected in its Precambrian history of deep crustal tectonics and a Phanerozoic history of biodiversity that fluctuated between cosmopolitanism and parochialism. Both vicariance and dispersal events over the past 90 Ma have blended a unique endemism on Madagascar, now in decline following rapid extinctions that started about 2000 years ago.

Introduction: To quantify the distribution of morphologic appearances of urethral anatomy and measure variables of urethral sphincter anatomy in continent, nulliparous, pregnant women by high resolution magnetic resonance imaging (MRI). Materials and methods: We studied fifteen women during their first pregnancy. We defined and quantified bladder neck and urethral morphology on axial and sagittal MR images from healthy, continent women. Results: The mean (±standard deviation) total transverse urethral diameter, anterior–posterior diameter, unilateral striated sphincter muscle thickness, and striated sphincter length were 15 ± 2 mm (range: 12–19 mm), 15 ± 2 mm (range: 11–20 mm), 2 ± 1 mm (range: 1–4 mm), and 13 ± 3 mm (range: 9–18 mm) respectively. The mean (±standard deviation) total urethral length on sagittal scans was 22 ± 3 mm (range: 17.6–26.4 mm). Discussion: Advances in MR technique combined with anatomical and histological findings will provide an insight to understand how changes in urethral anatomy might affect the continence mechanisms in pregnant and non-pregnant, continent or incontinent individuals.

Fasting and Urinary Stones

Directory of Open Access Journals (Sweden)

Ali Shamsa

2013-11-01

Full Text Available Introduction: Fasting is considered as one of the most important practices of Islam, and according to Prophet Mohammad, fasting is obligatory upon Muslims. The aim of this study is to evaluate the effects of fasting on urinary stones. Materials and Methods: Very few studies have been carried out on urinary stones and the effect of Ramadan fasting. The sources of the present study are Medline and articles presented by local and Muslim researchers. Meanwhile, since we are acquainted with three well-known researchers in the field of urology, we contacted them via email and asked for their professional opinions. Results: The results of studies about the relationship of urinary stones and their incidence in Ramadan are not alike, and are even sometimes contradictory. Some believe that increased incidence of urinary stones in Ramadan is related not to fasting, but to the rise of weather temperature in hot months, and an increase in humidity. Conclusion: Numerous biological and behavioral changes occur in people who fast in Ramadan and some researchers believe that urinary stone increases during this month.

Ileal conduit remains a widely used urinary diversion performed after radical cystectomy. However, complications of ileal conduits remain an important concern in urological surgery. We report a rare case of an ileal conduit stricture, which can have grim complications if unobserved during the operation. Following an initial operation of radical cystectomy and ileal conduit formation in France in 2011, an 80-year-old male travelled back to the UK after 4 months of general weakness and limb par...

The urinary protein/creatinine ratio [Up/Ucr (g/gCr)] has been used in the clinical management of patients with chronic kidney disease (CKD). However, a discrepancy is often noted between the Up/Ucr and 24-h urinary protein excretion [24hUp (g/day)] in patients with extremes of muscle mass. We examined devised a method for precise estimation of the 24-h urinary protein excretion (E-24hUp) based on estimation of 24-h urinary creatinine output (E-24hCr). Three parameters, spot Up/Ucr, 24hUP and E-24hUp (=Up/Ucr × E-24hCr), were determined in 116 adult patients with CKD. The correlations among the groups were analyzed. There was a significant correlation between the Up/Ucr and 24hUp (p high urinary protein group (>3.5 g/day). There was a significant correlation between the Up/Ucr and 24hUp in the low (p = 0.04) and high urinary protein (p = 0.01) groups, whereas the correlation coefficient was lower in the intermediate urinary protein (p = 0.07) group. Thus, we found a significant correlation between 24hUp and E-24hUp in the study population overall (p high urinary protein group (p < 0.001). We conclude that a poor correlation exists between the Up/Ucr and 24hUp in patients with intermediate urinary protein excretion levels. The recommended parameter for monitoring proteinuria in such patients may be the E-24hUp, which is calculated using the E-24hCr.

Patients often exhibit urinary retention following a stroke. Various neuropathological and animal studies have implicated the medulla oblongata, pons, limbic system, frontal lobe as areas responsible for micturition control, although the exact area responsible for urinary retention after stroke is not clear. The purpose of this study was to identify the stroke area responsible for urinary retention by localizing the areas where strokes occur. We assessed 110 patients with cerebral infarction and 27 patients with cerebral hemorrhage (78 men, 59 women; mean age, 73.0 years) who had been admitted to our hospital between October, 2012 and September, 2013. We used computed tomography (CT) and magnetic resonance imaging (MRI) to investigate the stroke location, and evaluated whether post-stroke urinary retention occurred. Twelve (8.8%) of the 137 patients (7 men, 5 women; mean age, 78.8 years) exhibited urinary retention after a stroke. Stroke occurred in the right/left dominant hemisphere in 7 patients; nondominant hemisphere in 1; cerebellum in 3; and brainstem in 1. Strokes in the dominant hemisphere were associated with urinary retention (P = 0.0314), particularly in the area of the insula (P < 0.01). We concluded that stroke affecting the insula of the dominant hemisphere tends to cause urinary retention.

The aim of this study was to evaluate midurethral tissue characteristics in continent and stress urinary incontinent postmenopausal women by using transvaginal ultrasound gray-level histogram. Thirty-seven patients with stress urinary incontinence (SUI) and 77 patients without SUI were evaluated. Vaginal ultrasound gray-level histograms were performed by 2 gynecologists blinded to patients' SUI statuses. The mean gray-level (MGL) of ultrasound gray-level histogram, representing the echogenicity of a region of interest, was measured in the anterior and posterior midurethral wall along a vertical ultrasound beam. The difference in MGL between anterior and posterior (AP difference) midurethra was calculated. The MGL value of SUI patients was found to be lower in posterior (p = 0.008) and higher in anterior midurethral region (p = 0.001) when compared with control group. In addition, the difference in MGL between anterior and posterior midurethra (AP difference) was found to be higher in SUI group (p < 0.001). Multivariate analysis by logistic regression including confounding factors revealed that AP difference was independently associated with presence of SUI (adjusted OR 1.14, 95% CI 1.08-1.20, p < 0.001). Intra- and inter-observer reproducibility was found to be high with intraclass correlation coefficient of 0.83 and 0.78, respectively. Postmenopausal SUI patients might have a distinct midurethral echogenicity pattern with the quantitative ultrasonography. © 2016 S. Karger AG, Basel.

Full Text Available Aim: To evaluate the association between urinary tract infection (UTI and urinary metabolites. Material and Method: Eighty children aged below 14 years old who were following for recurrent UTI were enrolled into the study. Urinary calcium (Uca, oxalate (Uox, citrate (Ucit and cysteine (Ucis levels were studied in 24 hours urine samples. Hypercalciuria, hyperoxaluria and hypocitraturia were identified according to the reference values. The positivity of sodium nitroprussid test was accepted as cystinuria. The results were compared between patients and control groups involving thirty children. The patients were divided into two subgroups according to the presence of renal scarring (RS on radionuclide scan. The similar comparisons were made between the subgroups. Results: There was no significant difference between the ratios of hypercalciuria, hypocitraturia and cystinuria in patient and control groups (p> 0.05. Uox/Ucr levels were significantly increased in patients compared to controls (p= 0.001 whereas Uca/Ucr and Ucit/Ucr levels were similar among study groups (p= 0. 082 and p= 0.466. There was no significant difference between RS (- and RS ( groups for hypercalciuria, hyperoxaluria, hypocitraturia and cystinuria (p> 0.05. Discussion: The increase in urinary excretion of oxalate might be a risk factor for UTI. There was no evidence regarding that urinary metabolic abnormalities such as hypercalciuria, hyperoxaluria, hypocitraturia and cystinuria have affected the development of RS in the setting of UTI.

Integrated Mid-Continent Carbon Capture, Sequestration & Enhanced Oil Recovery Project

A consortium of research partners led by the Southwest Regional Partnership on Carbon Sequestration and industry partners, including CAP CO2 LLC, Blue Source LLC, Coffeyville Resources, Nitrogen Fertilizers LLC, Ash Grove Cement Company, Kansas Ethanol LLC, Headwaters Clean Carbon Services, Black & Veatch, and Schlumberger Carbon Services, conducted a feasibility study of a large-scale CCS commercialization project that included large-scale CO{sub 2} sources. The overall objective of this project, entitled the 'Integrated Mid-Continent Carbon Capture, Sequestration and Enhanced Oil Recovery Project' was to design an integrated system of US mid-continent industrial CO{sub 2} sources with CO{sub 2} capture, and geologic sequestration in deep saline formations and in oil field reservoirs with concomitant EOR. Findings of this project suggest that deep saline sequestration in the mid-continent region is not feasible without major financial incentives, such as tax credits or otherwise, that do not exist at this time. However, results of the analysis suggest that enhanced oil recovery with carbon sequestration is indeed feasible and practical for specific types of geologic settings in the Midwestern U.S.

Urinary Tract Infections in Children

Full Text Available Urinary tract infections (UTI are frequent conditions in children. Untreated urinary tract infections can lead to serious kidney problems that could threaten the life of the child. Therefore, early detection and treatment of urinary tract infection is important. In older children, urinary tract infections may cause obvious symptoms such as stomach ache and disuria. In infants and young children, UTIs may be harder to detect because of less specific symptoms. Recurrences are common in children with urinary abnormalities such as neurogenic bladder, vesicourethral reflux or those with very poor toilet and hygiene habits. This article reviews the diagnostic approach and presents the current data related to the roles of radiologic imaging, surgical correction and antibiotic prophylaxis of UTIs in children.

Reformulating opioid analgesics to deter abuse is one approach toward improving their benefit-risk balance. To assess sentiment and attempts to defeat these products among difficult-to-reach populations of prescription drug abusers, evaluation of posts on Internet forums regarding reformulated products may be useful. A reformulated version of OxyContin (extended-release oxycodone) with physicochemical properties to deter abuse presented an opportunity to evaluate posts about the reformulation in online discussions. The objective of this study was to use messages on Internet forums to evaluate reactions to the introduction of reformulated OxyContin and to identify methods aimed to defeat the abuse-deterrent properties of the product. Posts collected from 7 forums between January 1, 2008 and September 30, 2013 were evaluated before and after the introduction of reformulated OxyContin on August 9, 2010. A quantitative evaluation of discussion levels across the study period and a qualitative coding of post content for OxyContin and 2 comparators for the 26 month period before and after OxyContin reformulation were conducted. Product endorsement was estimated for each product before and after reformulation as the ratio of endorsing-to-discouraging posts (ERo). Post-to-preintroduction period changes in ERos (ie, ratio of ERos) for each product were also calculated. Additionally, post content related to recipes for defeating reformulated OxyContin were evaluated from August 9, 2010 through September 2013. Over the study period, 45,936 posts related to OxyContin, 18,685 to Vicodin (hydrocodone), and 23,863 to Dilaudid (hydromorphone) were identified. The proportion of OxyContin-related posts fluctuated between 6.35 and 8.25 posts per 1000 posts before the reformulation, increased to 10.76 in Q3 2010 when reformulated OxyContin was introduced, and decreased from 9.14 in Q4 2010 to 3.46 in Q3 2013 in the period following the reformulation.

Long Aftershock Sequences within Continents and Implications for Earthquake Hazard Assessment

Science.gov (United States)

Stein, S. A.; Liu, M.

2014-12-01

Recent seismicity in the Tangshan region in North China has prompted concern about a repetition of the 1976 M7.8 earthquake that destroyed the city, killing more than 242,000 people. However, the decay of seismicity there implies that the recent earthquakes are probably aftershocks of the 1976 event. This 37-year sequence is an example of the phenomenon that aftershock sequences within continents are often significantly longer than the typical 10 years at plate boundaries. The long sequence of aftershocks in continents is consistent with a simple friction-based model predicting that the length of aftershock sequences varies inversely with the rate at which faults are loaded. Hence the slowly-deforming continents tend to have aftershock sequences significantly longer than at rapidly-loaded plate boundaries. This effect has two consequences for hazard assessment. First, within the heavily populated continents that are typically within plate interiors, assessments of earthquake hazards rely significantly on the assumption that the locations of small earthquakes shown by the short historical record reflect continuing deformation that will cause future large earthquakes. This assumption would lead to overestimation of the hazard in presently active areas and underestimation elsewhere, if some of these small events are aftershocks. Second, successful attempts to remove aftershocks from catalogs used for hazard assessment would underestimate the hazard, because much of the hazard is due to the aftershocks, and the declustering algorithms implicitly assume short aftershock sequences and thus do not remove long-duration ones.

Excessive urinary calcium excretion is the major risk of urinary stone formation. Very few population studies have been performed to determine the relationship between environmental cadmium exposure and urinary stone disease. This population-based study examined an association between urinary cadmium excretion, a good biomarker of long-term cadmium exposure, and prevalence of urinary stones in persons aged 15 years and older, who lived in the 12 cadmium-contaminated villages in the Mae Sot District, Tak Province, northwestern Thailand. A total of 6748 persons were interviewed and screened for urinary cadmium and urinary stone disease in 2009. To test a correlation between urinary excretion of cadmium and calcium, we measured urinary calcium content in 1492 persons, who lived in 3 villages randomly selected from the 12 contaminated villages. The rate of urinary stones significantly increased from 4.3% among persons in the lowest quartile of urinary cadmium to 11.3% in the highest quartile. An increase in stone prevalence with increasing urinary cadmium levels was similarly observed in both genders. Multiple logistic regression analysis revealed a positive association between urinary cadmium levels and stone prevalence, after adjusting for other co-variables. The urinary calcium excretion significantly increased with increasing urinary cadmium levels in both genders, after adjusting for other co-variables. Elevated calciuria induced by cadmium might increase the risk of urinary stone formation in this environmentally exposed population. - Research highlights: → Excessive calciuria is the major risk of urinary stone formation. → We examine cadmium-exposed persons for urinary cadmium, calcium, and stones. → The rate of urinary stones increases with increasing urinary cadmium. → Urinary calcium excretion increases with increasing urinary cadmium. → Elevated calciuria induced by cadmium may increase the risk of urinary stones.

Tropical forests are global centres of biodiversity and carbon storage. Many tropical countries aspire to protect forest to fulfil biodiversity and climate mitigation policy targets, but the conservation strategies needed to achieve these two functions depend critically on the tropical forest tree diversity-carbon storage relationship. Assessing this relationship is challenging due to the scarcity of inventories where carbon stocks in aboveground biomass and species identifications have been simultaneously and robustly quantified. Here, we compile a unique pan-tropical dataset of 360 plots located in structurally intact old-growth closed-canopy forest, surveyed using standardised methods, allowing a multi-scale evaluation of diversity-carbon relationships in tropical forests. Diversity-carbon relationships among all plots at 1 ha scale across the tropics are absent, and within continents are either weak (Asia) or absent (Amazonia, Africa). A weak positive relationship is detectable within 1 ha plots, indicating that diversity effects in tropical forests may be scale dependent. The absence of clear diversity-carbon relationships at scales relevant to conservation planning means that carbon-centred conservation strategies will inevitably miss many high diversity ecosystems. As tropical forests can have any combination of tree diversity and carbon stocks both require explicit consideration when optimising policies to manage tropical carbon and biodiversity.

Fear and overprotection in Australian residential aged-care facilities: The inadvertent impact of regulation on quality continence care.

Science.gov (United States)

Ostaszkiewicz, Joan; O'Connell, Beverly; Dunning, Trisha

2016-06-01

Most residents in residential aged-care facilities are incontinent. This study explored how continence care was provided in residential aged-care facilities, and describes a subset of data about staffs' beliefs and experiences of the quality framework and the funding model on residents' continence care. Using grounded theory methodology, 18 residential aged-care staff members were interviewed and 88 hours of field observations conducted in two facilities. Data were analysed using a combination of inductive and deductive analytic procedures. Staffs' beliefs and experiences about the requirements of the quality framework and the funding model fostered a climate of fear and risk adversity that had multiple unintended effects on residents' continence care, incentivising dependence on continence management, and equating effective continence care with effective pad use. There is a need to rethink the quality of continence care and its measurement in Australian residential aged-care facilities. © 2015 AJA Inc.

Children with recurrent urinary tract infections (rUTI) often show no identifiable cause of their infections. Neutrophil gelatinase-associated lipocalin (NGAL) is known to be upregulated within the uroepithelium and kidney of patients with UTI and exhibits a localized bacteriostatic effect through iron chelation. We hypothesize that some patients with rUTI without an identifiable cause of their recurrent infections have locally deficient NGAL production. We therefore explored whether a lack of NGAL production may be a factor in the pathogenesis of rUTI. Patients seen in the urology clinic for rUTI who were tract, or other reasons that predispose to UTI, such as neurogenic bladder, the need for intermittent catheterization, or unrepaired posterior urethral valves. Control patients were healthy children enrolled from the emergency department with no history of UTI or renal dysfunction, normal urinalysis at the time of enrollment, and presenting no diagnosis associated with increased NGAL levels, such as acute kidney injury or infection. NGAL was measured by immunoblot. Fifteen cases and controls were enrolled. Median urinary NGAL levels were significantly decreased in rUTI patients compared with controls [15 (14-29) ng/ml vs 30 (27-61) ng/ml; p = 0.002)] Although comparatively diminished, measurable NGAL levels were present in all patients with rUTI. Urinary NGAL is significantly decreased in patients with compared with patients without rUTI. These data suggest that some patients with rUTI may be predisposed to UTI because of a relative local deficiency in urinary NGAL production.

To investigate whether posterior and anterior fixation of the vesicourethral anastomosis during robotic radical prostatectomy (RRP) helps to establish continence earlier. Forty-seven consecutive patients undergoing RRP were randomized into two groups. The first group received a typical Van Velthoven vesicourethral anastomosis and the second group a modified anastomosis with posterior and anterior fixation. In this group the posterior fibrous tissues of the sphincter were sutured to the residual Denonvilliers' fascia. The anastomosis with two running sutures started at the 6 o'clock position on the bladder neck and continued upwards. Two-step stitching was done on the upper half of the anastomosis to ensure good stabilization of the bladder: a small portion of urethral stump followed by a deep haemostatic stitch on the plexus. Continence, as measured by patient self-reporting of the number of pads used per 24 h, was assessed 7 weeks after catheter removal, by telephone interview. The use of no pads or one pad was defined as "continent", two pads as "moderate incontinence" and more than two pads as "severe incontinence". At catheter removal, more patients in the fixation group were continent than in the Van Velthoven group [9/23 (39%) vs 3/24 (12.5%), p = 0.036]. At 7 weeks, continence was even better in the fixation group [15/23 (65%) vs 8/24 (33%), p = 0. 029]. The mean pad usage was less in the fixation group (1.43 vs 2.25, p = 0.032). The posterior and anterior fixation of the vesicourethral anastomosis during RRP results in an intact sphincteric mechanism, because no stretch is applied to the urethra, resulting in earlier continence.

Acute urinary tract infection (UTI) is an important cause of morbidity in children and may be complicated by congenital urinary tract abnormalities of a functional or anatomic nature which, predispose to recurrent UTI's that in turn may lead to renal failure and hypertension. Early radiologic and ultrasonographic investigations may reveal these anatomic anomalies in particular because the urinary tract, specifically in children, is not readily accessible to adequate clinical examinations Excretory urography (EU) has been considered as the 'gold standard' of upper urinary tract visualization, while the voiding cystourethrogram (VCUG) was thought to be the preferential method of imaging of the lower urinary tract. Recently, major technical advances have altered this commonly accepted diagnostic workup. Although ultrasonography, radio-nuclide scanning and urodynamics have become important contributors to the understanding of pathophysiology of UTI's their value and place in assessment of the sequence of imaging has not been comprehensively studied. This thesis deals about the optimization of the choice and the order of the different imaging techniques used in the evaluation of children, younger than six year with UTI.

Urinary incontinence symptoms are highly prevalent among women, have a substantial effect on health-related quality of life and are associated with considerable personal and societal expenditure. Two main types are described: stress urinary incontinence, in which urine leaks in association with physical exertion, and urgency urinary incontinence, in which urine leaks in association with a sudden compelling desire to void. Women who experience both symptoms are considered as having mixed urinary incontinence. Research has revealed overlapping potential causes of incontinence, including dysfunction of the detrusor muscle or muscles of the pelvic floor, dysfunction of the neural controls of storage and voiding, and perturbation of the local environment within the bladder. A full diagnostic evaluation of urinary incontinence requires a medical history, physical examination, urinalysis, assessment of quality of life and, when initial treatments fail, invasive urodynamics. Interventions can include non-surgical options (such as lifestyle modifications, pelvic floor muscle training and drugs) and surgical options to support the urethra or increase bladder capacity. Future directions in research may increasingly target primary prevention through understanding of environmental and genetic risks for incontinence. PMID:28681849

Management of the devastated posterior urethra and bladder neck: refractory incontinence and stenosis.

Anderson, Kirk M; Higuchi, Ty T; Flynn, Brian J

Stricture of the proximal urethra following treatment for prostate cancer occurs in an estimated 1-8% of patients. Following prostatectomy, urethral reconstruction is feasible in many patients. However, in those patients with prior radiation therapy (RT), failed reconstruction, refractory incontinence or multiple comorbidities, reconstruction may not be feasible. The purpose of this article is to review the evaluation and management options for patients who are not candidates for reconstruction of the posterior urethra and require urinary diversion. Patient evaluation should result in the decision whether reconstruction is feasible. In our experience, risk factors for failed reconstruction include prior radiation and multiple failed endoscopic treatments. Pre-operative cystoscopy is an essential part of the evaluations to identify tissue necrosis, dystrophic calcification, or tumor in the urethra, prostate and/or bladder. If urethral reconstruction is not feasible it is imperative to discuss options for urine diversion with the patient. Treatment options include simple catheter diversion, urethral ligation, and both bladder preserving and non-preserving diversion. Surgical management should address both the bladder and the bladder outlet. This can be accomplished from a perineal, abdominal or abdomino-perineal approach. The devastated bladder outlet is a challenging problem to treat. Typically, patients undergo multiple procedures in an attempt to restore urethral continuity and continence. For the small subset who fails reconstruction, urinary diversion provides a definitive, "end-stage" treatment resulting in improved quality of life.

To report the image-guided hypofractionated radiotherapy (hypo-IGRT) outcome for patients with localised prostate cancer according to the new outcome models Trifecta (cancer control, urinary continence, and sexual potency) and SCP (failure-free survival, continence and potency). Between August 2006 and January 2011, 337 patients with cT1-T2N0M0 prostate cancer (median age 73 years) were eligible for a prospective longitudinal study on hypo-IGRT (70.2 Gy/26 fractions) in our Department. Patients completed four questionnaires before treatment, and during follow-up: the International Index of Erectile Function-5 (IIEF-5), the International Prostate Symptom Score (IPSS), and the European Organization for Research and Treatment of Cancer prostate-cancer-specific Quality of Life Questionnaires (QLQ) QLQ-PR25 and QLQ-C30. Baseline and follow-up patient data were analysed according to the Trifecta and SCP outcome models. Cancer control, continence and potency were defined respectively as no evidence of disease, score 1 or 2 for item 36 of the QLQ-PR25 questionnaire, and total score of >16 on the IIEF-5 questionnaire. Patients receiving androgen-deprivation therapy (ADT) at any time were excluded. Trifecta criteria at baseline were met in 72 patients (42% of all ADT-free patients with completed questionnaires). Both at 12 and 24 months after hypo-IGRT, 57% of the Trifecta patients at baseline were still meeting the Trifecta criteria (both oncological and functional success according to the SCP model). The main reason for failing the Trifecta criteria during follow-up was erectile dysfunction: in 18 patients after 6 months follow-up, in 12 patients after 12 months follow-up, and in eight patients after 24 months. Actuarial 2-year Trifecta failure-free survival rate was 44% (95% confidence interval 27-60%). In multivariate analysis no predictors of Trifecta failure were identified. Missing questionnaires was the main limitation of the study. The Trifecta and SCP

The Aristotelian continence: channeling of righteous actions in the scientist´s experiments with animals

Full Text Available In Aristotelian ethics, the virtue of continence is responsible for mastering the soul and direct it towards the right reason; thus the continent, knowing that passions are bad does not follow them because of the reason; this virtuous is the one who subdues the passions, since both, reason and passions, oppose each other. For Aristotle the desire is the beginning of the action, followed by the discussion leading to choose the best and the most perfect virtuous action. It is important for bioethics that the virtue of continence applies to the actions of scientists who use animals for experimentation and that all their actions are mediated by the good actions. This article will deal with the virtue of continence as the channeling of actions mediated by right reason in the scientist who is experimenting with animals.

Oceans and continents: Similarities and differences in the mechanisms of heat loss

The principal objective of this paper is to present a simple and self-consistent review of the basic physical processes controlling heat loss from the earth. To accomplish this objective, we give a short summary of the oceanic and continental data and compare and contrast the respective mechanisms of heat loss . In the oceans we concentrate on the effect of hydrothermal circulation, and on the continents we consider in some detail a model relating surface heat flow to varying depth scales for the distribution of potassium, thorium, and uranium. From this comparison we conclude that the range in possible geotherms at depths below 100 to 150 km under continents and oceans overlaps and the thermal structure beneath an old stable continent is indistinguishable from that beneath an ocean were it at equilibrium. Oceans and continents are part of the same thermal system. Both have an upper rigid mechanical layer where heat loss is by conduction and a lower thermal boundary layer where convection is dominant. The simple conductive definition of the plate thickness is an oversimplification. The observed distribution of area versus age in the ocean allows us to investigate the dominant mechanism of heat loss which is plate creation. This distribution and an understanding of the heat flow through oceans and continents can be used to calculate the heat loss of the earth. This heat loss is 10 13 cal/s (4.2 x 10 13 W) of which more than 60% results from the creation of oceanic plate. The relation between area and age of the oceans is coupled to the ridge and subducting slab forces that contribute to the driving mechanism for plate motions. These forces are self-regulating and maintain the rate of plate generation required to achieve a balance between heat loss and heat generation

The association between parents who suffered daytime incontinence as children and children who are incontinence has been reported. However, the association of lower urinary tract (LUT) dysfunction in children and urinary symptoms in mothers has not been studied. To test the hypothesis that the children of mothers with lower urinary tract symptoms (LUTS) are more likely to have urinary symptoms. A cross-sectional multicenter study was conducted in two cities in Brazil. Children/adolescents of 5-17 years of age and their mothers were interviewed. Children with neurological problems, previously detected urinary tract abnormalities or who refused to sign the informed consent or assent form were excluded. The DVSS questionnaire was used to evaluate the presence of LUTS in the children and the ICIQ-OAB questionnaire was used to evaluate their mothers. Constipation in the children was investigated using the ROME III criteria. A total of 827 mother-child pairs were included, with 414 of the children (50.06%) being male. Mean age was 9.1 ± 2.9 years for the children and 35.9 ± 6.5 years for the mothers. Urinary symptoms (occurring at least once or twice a week) were present in 315 children (38.1%), incontinence in 114 (13.8%) and urinary urgency in 141 (17%). Of the mothers, 378 (45.7%) had at least one LUTS, with 103 (12.5%) having incontinence and 153 (18.5%) urgency. According to the DVSS, the overall prevalence of LUT dysfunction was 9.1%. The children's DVSS scores were significantly associated with the mothers' ICIQ-OAB scores (p urinary symptoms were 2.5 times more likely to have a child with LUT dysfunction (95%CI: 1.52-4.17; p factors of the presence of LUT dysfunction in the child. Children of mothers with incontinence and urinary urgency were also more likely to have incontinence and urgency. Mothers with typical symptoms of overactive bladder are more likely to have a child with LUT dysfunction. This correlation is also positive for the isolated symptoms

Mitochondrial diversity patterns and the Magdalenian resettlement of Europe: new insights from the edge of the Franco-Cantabrian refuge.

Phylogeography of the mitochondrial lineages commonly found in Western Europe can be interpreted in the light of a postglacial resettlement of the continent. The center of this proposal lies in the Franco-Cantabrian glacial refuge, located in the northern Iberian Peninsula and Southwestern France. Recently, this interpretation has been confronted by the unexpected patterns of diversity found in some European haplogroups. To shed new lights on this issue, research on Iberian populations is crucial if events behind the actual genetics of the European continent are to be untangled. In this regard, the region of Asturias has not been extensively studied, despite its convoluted history with prolonged periods of isolation. As mitochondrial DNA is a kind of data that has been commonly used in human population genetics, we conducted a thorough regional study in which we collected buccal swabs from 429 individuals with confirmed Asturian ancestry. The joint analysis of these sequences with a large continent-wide database and previously published diversity patterns allowed us to discuss a new explanation for the population dynamics inside the Franco-Cantabrian area, based on range expansion theory. This approximation to previously contradictory findings has made them compatible with most proposals about the postglacial resettlement of Western Europe.

Given that YKL-40 is a known marker of inflammation, we sought to determine its association with urinary tract infection (UTI) in febrile children. In total, 44 children aged 0 to 24 months with febrile UTI and 35 age- and sex-matched controls with fever from other causes were enrolled in the study. ELISA was performed to determine the level of YKL-40 in urine collected from each child. The ratio of urinary YKL-40 to creatinine (Cr) was higher in the children with a UTI than in the controls (PUTI was 0.88 for the urinary YKL-40/Cr ratio, 0.86 for pyuria, and 0.71 for positive nitrite on urinalysis. We applied a cut-off value of 125.23 pg/mg to urinary YKL-40/Cr for detecting UTI. Eight of nine children in the control group with pyuria had urinary YKL-40/Cr levels lower than 125.23 pg/mg, and the one child in the UTI group without pyuria or positive nitrite had a urinary YKL-40/Cr level greater than 125.23 pg/mg. Determining the levels of urinary YKL-40/Cr may help identify true cases of UTI in febrile young children, especially when they have pyuria but not nitrite, or have neither pyuria nor nitrite in the urine. © The Korean Society for Laboratory Medicine

Leiomyoma of the urinary bladder is a rare benign mesenchymal tumour. We describe here a case of leiomyoma of the urinary bladder in a 65-year-old gentleman who presented with haematuria, passage of clots and combined obstructive and irritative urinary symptoms. The investigations revealed a vesical calculus and a mass on the left lateral wall of the urinary bladder. Cystolitholapaxy and transurethral resection of the tumour was performed. Histopathological report of the resected tumour revealed a leiomyoma of the urinary bladder. So far, a leiomyoma of the urinary bladder and a concomitant vesical calculus have not been described in literature. (author)

To determine the prevalence of female urinary incontinence (UI) and its impact on quality of life. In a Dutch national postal questionnaire survey, 1460 spouses of 1771 men in the town of Boxmeer, age-stratified and randomly selected, were asked to participate. The prevalence of UI in the women was assessed in two ways. First, a total score on a short UI-specific questionnaire differentiated them into three groups, i.e. no symptoms (score 0-2), minimally (3-6) or severely incontinent (7-14). Second, a self-reported UI prevalence was calculated by asking respondents if they ever had urine loss. To conform to the International Continence Society standard definition, spouses were also asked to complete a general (Short Form-12) and lower urinary tract disease-specific quality-of-life questionnaire, and were asked about their need to seek help. The questionnaires were returned by 1071 women (mean age 57 years, range 29-79; response rate 73%); 34% were regarded as minimally and 12% as severely incontinent. The self-reported UI rate was 40%. Disease-specific and general quality of life was significantly lower for women with UI than for those with minimal or no urine loss; 38% of incontinent respondents had consulted a physician for their UI, and among respondents with minimal complaints this was 28%. Up to 46% of the married female population had some degree of UI, and severe UI significantly compromised their quality of life.

Effect of urinary tract infection on the urinary metabolic characteristic as a risk factor in producing urolithiasis

Full Text Available Urinary metabolic disorders are one of the most common causes of stone formation in children. The purpose of this study was to evaluate the effect of urinary tract infections in the urinary metabolic characteristics as a risk factor in the incidence of urolithiasis. This case-control study was conducted in 222 children with urolithiasis in the range of 6 months to 16 years old in Sanandaj, Kurdistan, Iran during 2012-14. Patients were divided into two groups based on those with urinary tract infection and without urinary tract infection. Then, urine samples were collected from both groups, and levels of calcium, oxalate, citrate, uric acid, creatinine, and cysteine were measured. The collected information was analyzed using software SPSS (version 16. The ratio Average levels of calcium, magnesium, oxalate, cysteine, uric acid to creatinine in urine showed no significant difference between two groups based on statistical analysis. However, the amount of citrate to creatinine in children with urinary tract infection and urolithiasis was clearly less P=0.01. The results of this study show that the urinary tract infection cannot change the urinary metabolic characteristics, but it can be considered as a risk factor in kidney stone formation due to the reduced amount of citrate in the urine.

Antegrade continence enemas (ACE) are an efficacious therapeutic option for patients with fecal incontinence. The authors review their institution's experience with a variation of the Monti-Malone ACE procedure using the left colon as a source of an intestinal conduit and enema reservoir. From 2000 to 2002, 18 patients with fecal incontinence or intractable constipation underwent left-colon ACE (LACE) procedure. Concomitant Mitrofanoff appendicovesicostomy was performed in 15 patients and bladder augmentation in 9. The majority of patients had neural tube defects. A segment of left colon was tubularized, tunneled into the muscular wall of the distal colon, and exteriorized through the left upper quadrant or midabdomen. Stomal catherization and enema installation were started one month postoperatively. Fifteen patients (83%) achieved fecal continence, 2 remain incontinent of stool, and 1 experienced stomal closure (mean follow-up was 24 +/- 9 months). Two patients had stomal stenosis that required revision. The mean enema volume in patient's achieving continence was 360 +/- 216 mL, and the mean transit time was 18 +/- 12 minutes. LACE is an efficacious procedure for fecal incontinence that can be performed safely at the time of major urologic reconstruction. Administration of enemas into the left colon has several physiologic advantages that result in predictable bowel evacuation.

Purpose. To determine the clinical variables associated with bacteriuria in patients undergoing primary percutaneous antegrade urinary drainage procedures in order to predict the utility of routinely obtaining urine cultures at the time of the procedure. Methods. Between October 1995 and March 1998 urine cultures were prospectively obtained in all patients undergoing a primary percutaneous antegrade urinary drainage procedure. One hundred and eighty-seven patients underwent 264 procedures. Results were available in 252 cases. Culture results were correlated with clinical, laboratory, and demographic variables. Anaerobic cultures were not uniformly performed. Results. Urine cultures were positive in 24 of 252 (9.5%) cases. An indwelling or recently removed ipsilateral device (catheter or stent) and a history of previous cystectomy with urinary diversion were significant predictors of a positive culture. Patients without either of these predictors, and without clinical or laboratory evidence of infection, were rarely found to have positive cultures. Conclusion. The likelihood of a positive urine culture can be predicted on the basis of the aforementioned clinical variables. In the absence of these clinical indicators routine urine cultures are neither useful nor cost-effective

Parastomal hernias after radical cystectomy and ileal conduit diversion

Timothy F. Donahue

2016-07-01

Full Text Available Parastomal hernia, defined as an “incisional hernia related to an abdominal wall stoma”, is a frequent complication after conduit urinary diversion that can negatively impact quality of life and present a clinically significant problem for many patients. Parastomal hernia (PH rates may be as high as 65% and while many patients are asymptomatic, in some series up to 30% of patients require surgical intervention due to pain, leakage, ostomy appliance problems, urinary obstruction, and rarely bowel obstruction or strangulation. Local tissue repair, stoma relocation, and mesh repairs have been performed to correct PH, however, long-term results have been disappointing with recurrence rates of 30%–76% reported after these techniques. Due to high recurrence rates and the potential morbidity of PH repair, efforts have been made to prevent PH development at the time of the initial surgery. Randomized trials of circumstomal prophylactic mesh placement at the time of colostomy and ileostomy stoma formation have shown significant reductions in PH rates with acceptably low complication profiles. We have placed prophylactic mesh at the time of ileal conduit creation in patients at high risk for PH development and found it to be safe and effective in reducing the PH rates over the short-term. In this review, we describe the clinical and radiographic definitions of PH, the clinical impact and risk factors associated with its development, and the use of prophylactic mesh placement for patients undergoing ileal conduit urinary diversion with the intent of reducing PH rates.

[Urinary tract infections in adults].

Michno, Mikolaj; Sydor, Antoni

Review of urinary tract infections in adults including etiology, pathogenesis, classification and the most important therapeutic recommendations. Urinary tract infections are still a common clinical problem occurring more often in sexually active women, pregnancy, elderly , after catherization of a urinary bladder and urological surgery as well as in the co-existence of diabetes or nephrolithiasis. Due to the anatomical differences, women suffer more often than men. The main etiological factor is Escherichia coli, even though it plays a lesser role in the complicated infections, than in non-complicated ones. Apart from that, the infections may also be caused by atypical microbes, viruses and fungi. Relapses as well as reinfections are typical features of urinary tract infections and in some cases prolonged infections can spread from lower to upper urinary tract contributing to pyelonephritis, urosepsis or even death. These long-term infections can progress in a hidden, insidious, oligosymptomatic or asymptomatic manner leading to irreversible, progressive deterioration of renal function. They can also mask other diseases such as tuberculosis or neoplasms of the urinary tract, which leads to the delayed diagnosis and treatment. Diagnosis and treatment of urinary tract infections is a complex problem, often requiring specialized procedures as well as hospitalization. The choice of a therapy is determined by the type of infection, general condition, age and coexisting diseases. Rapid diagnosis and implementation of proper pharmacotherapy may shorten the time of treatment and hospitalization, preventing serious complications and reinfections.

Synergistic muscle activation intensifies a woman’s ability to contract the PFM. In some cases, even for continent women, it is not possible to fully contract their PFM without involving the synergistic muscles. The primary aim of this study was to assess the surface electromyographic activity of synergistic muscles to PFM (SPFM during resting and functional PFM activation in postmenopausal women with and without SUI.Materials and methods: This study was a preliminary, prospective, cross-sectional observational study and included volunteers and patients who visited the Department and Clinic of Urology, University Hospital in Wroclaw, Poland. Forty-two patients participated in the study and were screened for eligibility criteria. Thirty participants satisfied the criteria and were categorized into two groups: women with SUI (n=16 and continent women (n=14. The bioelectrical activity of PFM and SPFM (AM, RA, GM was

Purpose: To report on the long-term urinary morbidity among prostate cancer patients with a prior history of a transurethral resection of the prostate (TURP) treated with high-dose 3-dimensional conformal radiotherapy (3D-CRT). Methods and Materials: Between 1988 and 1997, 1100 patients with clinically localized prostate cancer were treated with 3D-CRT. Of these, 120 patients (8%) were identified as having had a prior TURP and are the subjects of this analysis. The median age was 71 years (range: 49-83 years). The clinical stages of the patients were T1c: 33 (28%); T2a: 38 (32%); T2b: 15 (13%); and T3: 34 (27%). Neoadjuvant androgen ablation therapy was given to 39 (33%). The median radiation dose prescribed to the planning target volume was 75.6 Gy (range: 64.8-81 Gy). The median elapsed time from TURP to initiation of 3D-CRT was 69 months (range: 4-360 months). The median follow-up time was 51 months (range: 18-109 months). Results: Five patients of the 120 with a prior history of TURP (4%) developed a urethral stricture after 3D-CRT which was corrected with dilatation. The 5-year actuarial likelihood of ≥ Grade 2 late urinary toxicities was 9%. No Grade 4 urinary toxicities were observed in this group of patients. Among 110 patients who were completely continent of urine prior to 3D-CRT, 10 (9%) developed stress incontinence requiring 1 pad daily for protection or experienced occasional leakage (not requiring pad protection). The 5-year incidence of ≥ Grade 1 stress incontinence was 18% in patients who developed acute ≥ Grade 2 GU symptoms during the course of 3D-CRT compared to 7% for patients who experienced Grade 1 or no acute urinary symptoms (p = 0.05). The radiation dose (≥75.6 Gy vs. <75.6 Gy), the number of prior TURP procedures, or the volume of resected tissue at the time of TURP had no significant impact on the long-term urinary morbidity outcome. A multivariate analysis demonstrated that the presence of Grade 2 acute urinary symptoms was the

Functional outcomes after ileal bladder substitution reflect the expectations of future patients at a particular centre. The aim of this study was to use validated questionnaires and a pad-weighing test to investigate functional outcomes after neobladder reconstruction at long-term follow-up in patients at a single centre. During 2005 - 2015, 75 patients received a Studer ileal bladder substitute at the Department of Urology, Malmö. Forty-six of these patients were alive for follow-up and were evaluated using the pad-weighing test and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF), the Female Sexual Function Index (FSFI) and the International Index of Erectile Function (IIEF). Five of 37 evaluable patients (14%) were considered fully continent, reporting a pad-weighing test result of 0 g and an ICIQ-UI-SF score of 0. The median ICIQ-UI-SF score was 8 [interquartile range (IQR) 3-11], and seven patients (17%) were continent according to the ICIQ-UI-SF score only. In the pad-weighing test, 28 out of 37 patients (76%) reported 0 g day-time leakage whereas only 12 out of 37 patients (32%) reported 0 g night-time leakage. At follow-up, nine out of 39 (23%) of evaluable male patients were potent. The median ICIQ-UI-SF score was significantly lower during the second half of the study period [4 (IQR 0-8) vs 10 (IQR 6-14); p = .003]. The inverse applied to the median IIEF score [5 (IQR 3-12) vs 2 (IQR 1-4); p = .02]. Functional outcomes at long-term follow-up after radical cystectomy and Studer ileal bladder substitute were at best modest in this series. Better outcomes during the second half of the study period might be explained by improved patient selection and a refined surgical technique, but possibly also by longer follow-up of patients during the first half of the period resulting in a more pronounced time-dependent decline in functional outcomes.

Full Text Available The interest about Staphylococcus aureus (S. aureus and methicillin resistant S. aureus (MRSA in livestock, and domestic and wild animals has significantly increased. The spread of different clonal complexes related to livestock animals, mainly CC398, and the recent description of the new mecC gene, make it necessary to know more about the epidemiology and population structure of this microorganism all over the world. Nowadays, there are several descriptions about the presence of S. aureus and/or MRSA in different animal species (dogs, sheep, donkeys, bats, pigs, and monkeys, and in food of animal origin in African countries. In this continent, there is a high diversity of ethnicities, cultures or religions, as well as a high number of wild animal species and close contact between humans and animals, which can have a relevant impact in the epidemiology of this microorganism. This review shows that some clonal lineages associated with humans (CC1, CC15, CC72, CC80, CC101, and CC152 and animals (CC398, CC130 and CC133 are present in this continent in animal isolates, although the mecC gene has not been detected yet. However, available studies are limited to a few countries, very often with incomplete information, and many more studies are necessary to cover a larger number of African countries.

2013-01-01

To evaluate the relationship between child- and parent-reported quality of life (QOL) and bowel and bladder continence among young children with spina bifida (SB). 104 children ages 5-12 years and one of their parents/guardians completed the Pediatric Quality of Life Inventory - Generic Form (PedsQL; parent and child) and the Quality of Life in Spina Bifida Questionnaire (QOLSBQ, parent only). Data on continence, child age, and condition-specific variables were obtained by chart review. Parent and child QOL scores (on all measures of QOL) were positively correlated; parents rated child QOL lower than children's self report. QOL scores did not differ based on continence status. Total PedsQL scores were associated with age and mobility based on child report and with mobility based on parent report. QOL may not be affected by continence status among young children with SB, though demographic (i.e., age) and condition-specific (i.e., functional mobility status) variables appear relevant. Additional research is needed to further evaluate condition-specific variables, other protective variables, and possible measurement issues that influence QOL in young children with SB.

Origin of Urinary Oxalate

Science.gov (United States)

Holmes, Ross P.; Knight, John; Assimos, Dean G.

2007-04-01

Urinary oxalate is mostly derived from the absorption of ingested oxalate and endogenous synthesis. The breakdown of vitamin C may also contribute small amounts to the urinary oxalate pool. The amount of oxalate absorbed is influenced by the oxalate content of the diet, the concentrations of divalent cations in the gut, the presence of oxalate-degrading organisms, transport characteristics of the intestinal epithelium, and other factors associated with the intestinal environment. Knowledge of pathways associated with endogenous oxalate synthesis is limited. Urinary oxalate excretion can be modified using strategies that limit dietary oxalate absorption and the ingestion of oxalogenic substrates such as hydroxyproline.

With the objective of knowing the common etiological agents in urinary infection and comparing its antimicrobial susceptibility in nosocomial and community-acquired urinary infections, we analyse all the urine bacteriological exams from the Serviço de Patologia Clínica do Centro Hospitalar do Nordeste, EPE - Unidade Hospitalar de Bragança, during a two years period (April 2004 to March 2006). During this period, 4018 urine bacteriological exams were made. The cultural exam was positive in 572 samples (144 from nosocomial infections and 428 from community-acquired urinary infections). The Escherichia coli was the more isolated strain (68,4 %), followed by Klebsiella spp (7,9%), Pseudomonas aeruginosa (6,1%) and Proteus mirabilis (5,2%). Concerning to antimicrobial susceptibility, Escherichia coli and Klebsiella spp showed a high resistance to the antimicrobials Amoxicillin, Piperacillin, Cephalothin, Ceftazidim and Quinolones. For Enterobacteriaceae Imipenem, Amikacin and Netilmicin were the antimicrobials with more level of susceptibility. Imipenem and Amikacin were the more efficient antimicrobials against Pseudomonas aeruginosa. Concerning to the susceptibility for the same etiological agent, in nosocomial and community-acquired urinary infections, we founded statistical significant differences in the antimicrobials Ticarcillin-clavulanic acid and Collistin for Pseudomonas aeruginosa and in the group of antimicrobials from Quinolones for the Proteus mirabilis. In the other identified agents there were no statistical significant differences for antimicrobials. This study it allows making use of data necessary for the knowledge of etiologic urinary infection agents in Bragança and provides the information about the antimicrobials resistance, which were necessary to initiate an adequate empirical treatment and to elaborate treatment guides.

Radical cystectomy with orthotopic neobladder for invasive bladder cancer: a critical analysis of long term oncological, functional and quality of life results

Directory of Open Access Journals (Sweden)

Arnulf Stenzl

2010-10-01

Full Text Available PURPOSE: Analyze current knowledge and practice regarding tumor-related cystectomy with subsequent orthotopic neobladder both in male and female patients. DESIGN, SETTING, AND PARTICIPANTS: Evaluate literature predominantly from the last decade dealing with long-term experience in large numbers of patients with an orthotopic neobladder following cystectomy. Oncological outcome specific to an orthotopic neobladder, functional aspects such as urinary continence, renal function, sexual activity and other quality of life issues are elucidated. RESULTS: Local pelvic recurrences after urothelial bladder cancer occur in 7-12%. Urethral second primary tumors in male and female patients in contemporary series with bladder substitution are 4-6% and 1.4 o 4%, respectively. Upper tract recurrences vary between 2.4-17%. Complications regarding the upper urinary tract have dramatically diminished due to simplified forms of upper tract protection as well as a more refined technique of ureterointestinal anastomosis. Depending on the technique ureteroileal stenosis was lately reported to lie between 2.7 to 3.8%. Renal function remained stable in 96% after a mean follow-up of up to 5 years. Radical cystectomy in carefully selected patients has stood the test of time by providing adequate long-term survival and low local recurrence rates. Orthotopic bladder substitution does not compromise oncological outcome, yields excellent functional results, is cost effective compared to other types of urinary diversion, may improve quality of life and should therefore be the diversion of choice both in men and women. Chronological age is generally not a contraindication for cystectomy, but for orthotopic urinary diversion, tumor extent, functional pelvic floor deficits and general life expectancy are limiting factors.

Validity of urinary monoamine assay sales under the "spot baseline urinary neurotransmitter testing marketing model".

Science.gov (United States)

Hinz, Marty; Stein, Alvin; Uncini, Thomas

2011-01-01

Spot baseline urinary monoamine assays have been used in medicine for over 50 years as a screening test for monoamine-secreting tumors, such as pheochromocytoma and carcinoid syndrome. In these disease states, when the result of a spot baseline monoamine assay is above the specific value set by the laboratory, it is an indication to obtain a 24-hour urine sample to make a definitive diagnosis. There are no defined applications where spot baseline urinary monoamine assays can be used to diagnose disease or other states directly. No peer-reviewed published original research exists which demonstrates that these assays are valid in the treatment of individual patients in the clinical setting. Since 2001, urinary monoamine assay sales have been promoted for numerous applications under the "spot baseline urinary neurotransmitter testing marketing model". There is no published peer-reviewed original research that defines the scientific foundation upon which the claims for these assays are made. On the contrary, several articles have been published that discredit various aspects of the model. To fill the void, this manuscript is a comprehensive review of the scientific foundation and claims put forth by laboratories selling urinary monoamine assays under the spot baseline urinary neurotransmitter testing marketing model.

Suskind, Anne M

2017-09-01

The incidence of both frailty and lower urinary tract symptoms, including urinary incontinence, overactive bladder, underactive bladder, and benign prostatic hyperplasia, increases with age. However, our understanding of the relationship between frailty and lower urinary tract symptoms, both in terms of pathophysiology and in terms of the evaluation and management of such symptoms, is greatly lacking. This brief review will summarize definitions and measurement tools associated with frailty and will also review the existing state of the literature on frailty and lower urinary tract symptoms in older individuals.

Could Urinary Tract Infection Cause Female Stress Urinary Incontinence? A Clinical Study.

Science.gov (United States)

Heydari, Fatemeh; Motaghed, Zahra; Abbaszadeh, Fatemeh

2016-01-01

Stress urinary incontinence (SUI), the most common type of urinary incontinence (UI), is usually defined as leakage of urine during movement or activity which puts pressure on the bladder, such as coughing, sneezing, running or heavy lifting. It is reported in most countries that 15% to 40% of women struggle with SUI and its severe implications for daily life, including social interactions, sexuality, and psychological wellbeing. The aim of our study was to assess the relationship between urinary tract infection and the severity of stress urinary incontinence (SUI). This research was a cross-sectional study conducted in a public urology clinic in Tehran. The study population was all females with complaints of SUI who visited the clinic during 2014. We compared Valsalva leak point pressure (VLPP) in two groups of patients, with and without history of urinary tract infection (UTI). According to the findings of our study, the mean VLPP was 83.10 cm H2O in the group with UTI history, and 81.29 cm H2O in those without history of UTI. The difference in VLPP between the two groups was not significant (P < 0.05), even after controlling for confounding variables including age, body mass index, history of hysterectomy and number of deliveries. Our study did not confirm a significant relationship between UTI and severity of SUI as measured by VLPP. A decisive opinion would require extensive future studies by prospective methods.

Evaluation of the anatomic location of the distended and empty urinary bladders and urethras of healthy adult male and female dogs and cats by retrograde urethrocystography revealed substantial variations. In 15 dogs in lateral recumbency with empty bladder lumens, the caudal portion of the urinary bladder was within the pelvic canal in 5 of 7 male and 5 of 8 female dogs. In female dogs examined in ventrodorsal recumbency, only 4 of 8 had the empty urinary bladders in part within the pelvic canal. After luminal distention, 3 of 7 male and 3 of 8 female dogs, while in lateral recumbency, had the urinary bladders in part intrapelvically. However, when female dogs were placed in ventrodorsal recumbency, only 1 of 7 urinary bladders was in part within the pelvis. The urinary bladders of 14 cats were consistently within the abdominal cavity, irrespective of whether the bladder lumen was distended or empty. Urethral flexures occurred in dogs with intrapelvic bladders that were distended or empty. Urethral flexures were not found in cats. The urethras of dogs and cats in lateral recumbency were generally closer to the floor of the pelvis after urinary bladder distention than when the bladder was empty. The urethra of the dogs and cats in ventrodorsal recumbency was to the left or right of or on the midsagittal plane, whether the urinary bladder was empty or distended. A greater degree of lateral displacement was encountered in ventrodorsal recumbency after urinary bladder distention

To evaluate the frequency of urinary peritonitis in children and to highlight its terms of management in a country with limited resources. We retrospectively observed nine case reports of urinary peritonitis collected in surgical reanimation service at the CHU of Antananarivo, from 1st January 2009 to 31 December 2012. Urinary peritonitis accounts 0.5% of all pediatric abdominal emergencies and 5% of pediatric urological emergencies collected in our service during study period. Three etiologies were traumatic bladder rupture, one bladder iatrogenic rupture, four secondary to obstructive uropathy and one other after cystolithotomy. We found a new case of posttraumatic transverse rupture of the bladder neck. Among obstructive uropathy observed, there were two cases of posterior urethral valves and two cases of ureteralpelvic junction obstruction. Clinical expression was dominated by fever, with abdominal distention and defense. In majority of cases, etiological diagnosis was made intraoperatively. The surgical treatment by laparotomy was performed under cover of systemic antibiotic therapy. Evolution was complicated with sepsis in three cases and acute renal failure in both cases. Surgical follow-up without complication were observed in four cases. A child has died to septic shock and multivisceral failure. Unlike urinary ascites resulting a transperitoneal extravasation of urine, uroperitoneum was a fistula between adominal cavity and content of the urinary tract. Urinary ascites was a rare cause of peritonitis. In contrast, uroperitoneum caused peritonitis quickly. Urinary peritonitis was a rare entity but severe prognosis in children. In majority of cases, etiological diagnosis was made intraoperatively. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Assessment of bioelectrical activity of synergistic muscles during pelvic floor muscles activation in postmenopausal women with and without stress urinary incontinence: a preliminary observational study.

Muscles such as adductor magnus (AM), gluteus maximus (GM), rectus abdominis (RA), and abdominal external and internal oblique muscles are considered to play an important role in the treatment of stress urinary incontinence (SUI), and the relationship between contraction of these muscles and pelvic floor muscles (PFM) has been established in previous studies. Synergistic muscle activation intensifies a woman's ability to contract the PFM. In some cases, even for continent women, it is not possible to fully contract their PFM without involving the synergistic muscles. The primary aim of this study was to assess the surface electromyographic activity of synergistic muscles to PFM (SPFM) during resting and functional PFM activation in postmenopausal women with and without SUI. This study was a preliminary, prospective, cross-sectional observational study and included volunteers and patients who visited the Department and Clinic of Urology, University Hospital in Wroclaw, Poland. Forty-two patients participated in the study and were screened for eligibility criteria. Thirty participants satisfied the criteria and were categorized into two groups: women with SUI (n=16) and continent women (n=14). The bioelectrical activity of PFM and SPFM (AM, RA, GM) was recorded with a surface electromyographic instrument in a standing position during resting and functional PFM activity. Bioelectrical activity of RA was significantly higher in the incontinent group than in the continent group. These results concern the RA activity during resting and functional PFM activity. The results for other muscles showed no significant difference in bioelectrical activity between groups. In women with SUI, during the isolated activation of PFM, an increased synergistic activity of RA muscle was observed; however, this activity was not observed in asymptomatic women. This may indicate the important accessory contribution of these muscles in the mechanism of continence.

Background: Metallothionein (MT) proteins play critical roles in the physiological handling of both essential (Cu and Zn) and toxic (Cd) metals. MT expression is regulated by metal-regulatory transcription factor 1 (MTF1). Hence, genetic variation in the MT gene family and MTF1 might influence excretion of these metals. Methods: 321 women were recruited in Seattle, WA and Las Cruces, NM and provided demographic information, urine samples for measurement of metal concentrations by mass spectrometry and creatinine, and blood or saliva for extraction of DNA. Forty-one single nucleotide polymorphisms (SNPs) within the MTF1 gene region and the region of chromosome 16 encoding the MT gene family were selected for genotyping in addition to an ancestry informative marker panel. Linear regression was used to estimate the association of SNPs with urinary Cd, Cu, and Zn, adjusted for age, urinary creatinine, smoking history, study site, and ancestry. Results: Minor alleles of rs28366003 and rs10636 near the MT2A gene were associated with lower urinary Cd, Cu, and Zn. Minor alleles of rs8044719 and rs1599823, near MT1A and MT1B, were associated with lower urinary Cd and Zn, respectively. Minor alleles of rs4653329 in MTF1 were associated with lower urinary Cd. Conclusions: These results suggest that genetic variation in the MT gene region and MTF1 influences urinary Cd, Cu, and Zn excretion. - Highlights: • Genetic variation in metallothionein (MT) genes was assessed in two diverse populations. • Single nucleotide polymorphisms (SNPs) in MT genes were associated with mean urinary Cd, Cu and Zn. • Genetic variation may influence biomarkers of exposure, and associations of exposure with health.

Urinary catheters are widely used for hospitalized patients and are often associated with high rates of urinary tract infection. We evaluated in vitro the antiadherence activity of a novel antiseptic Gendine-coated urinary catheter against several multidrug-resistant bacteria. Gendine-coated urinary catheters were compared to silver hydrogel-coated Foley catheters and uncoated catheters. Bacterial biofilm formation was assessed by quantitative culture and scanning electron microscopy. These data were further correlated to an in vivo rabbit model. We challenged 31 rabbits daily for 4 days by inoculating the urethral meatus with 1.0 × 109 CFU streptomycin-resistant Escherichia coli per day. In vitro, Gendine-coated urinary catheters reduced the CFU of all organisms tested for biofilm adherence compared with uncoated and silver hydrogel-coated catheters (P < 0.004). Scanning electron microscopy analysis showed that a thick biofilm overlaid the control catheter and the silver hydrogel-coated catheters but not the Gendine-coated urinary catheter. Similar results were found with the rabbit model. Bacteriuria was present in 60% of rabbits with uncoated catheters and 71% of those with silver hydrogel-coated catheters (P < 0.01) but not in those with Gendine-coated urinary catheters. No rabbits with Gendine-coated urinary catheters had invasive bladder infections. Histopathologic assessment revealed no differences in toxicity or staining. Gendine-coated urinary catheters were more efficacious in preventing catheter-associated colonization and urinary tract infections than were silver hydrogel-coated Foley catheters and uncoated catheters.

2006-05-01

Full Text Available Background and Aim: This study was conducted to evaluate the safety and efficacy of Tension-free Tape for the surgical treatment of female stress urinary incontinence. Materials and Methods: In a prospective open study for pre and post operative, we followed 36 patients at least 1.5 years after surgery (18-28 months; all patients underwent the operation under local anesthesia, allowing the surgeon to check intra-operatively that continence has been obtained. Results: Mean operation time was 36 minutes (range 20-45 minutes. 32(89% of the patients was cured according to the protocol, another 3(8.3% were significantly improved and there was 1(2.7% failure. Mast of patients (about 91% were operated on a one day-care basis, which implies that they were released from the hospital the day after the procedure, and no post operative catheterization, defect healing and tape rejection occurred. Pain free recovery time without any analgesic was another benefit. Five patients needed an indwelling catheter for 3 days and two uncomplicated hematoma occurred. Conclusion: Based on the results, we conclude that Tension-free Vaginal Tape is a safe and effective ambulatory procedure for surgical treatment of genuine stress urinary incontinence, which allows the majority of the women to be discharged from the clinic the day after the procedure and start their works in the second week.

A Zn isotope perspective on the rise of continents.

Science.gov (United States)

Pons, M-L; Fujii, T; Rosing, M; Quitté, G; Télouk, P; Albarède, F

2013-05-01

Zinc isotope abundances are fairly constant in igneous rocks and shales and are left unfractionated by hydrothermal processes at pH 1‰ during the ~2.35 Ga Great Oxygenation Event. By 1.8 Ga, BIF δ(66) Zn has settled to the modern value of FeMn nodules and encrustations (~0.9‰). The Zn cycle is largely controlled by two different mechanisms: Zn makes strong complexes with phosphates, and phosphates in turn are strongly adsorbed by Fe hydroxides. We therefore review the evidence that the surface geochemical cycles of Zn and P are closely related. The Zn isotope record echoes Sr isotope evidence, suggesting that erosion starts with the very large continental masses appearing at ~2.7 Ga. The lack of Zn fractionation in pre-2.9 Ga BIFs is argued to reflect the paucity of permanent subaerial continental exposure and consequently the insignificant phosphate input to the oceans and the small output of biochemical sediments. We link the early decline of δ(66) Zn between 3.0 and 2.7 Ga with the low solubility of phosphate in alkaline groundwater. The development of photosynthetic activity at the surface of the newly exposed continents increased the oxygen level in the atmosphere, which in turn triggered acid drainage and stepped up P dissolution and liberation of heavy Zn into the runoff. Zinc isotopes provide a new perspective on the rise of continents, the volume of carbonates on continents, changing weathering conditions, and compositions of the ocean through time. © 2013 Blackwell Publishing Ltd.

To identify which independent variable would be strong predictor of febrile urinary tract infection (UTI) in children and adolescents with overactive bladder. A search was made of the institute's database for all patients diagnosed with overactive bladder over the preceding four years. Children and adolescents under 18 years of age with overactive bladder and no neurological or anatomical alterations of the lower urinary tract were included in the study. The independent variables were: sex, age, ethnicity (Brazilians of African descendence/others), the presence of urinary urgency, daytime incontinence, enuresis, frequent urination, infrequent voiding (≤3 voids/day), nocturia, holding maneuvers, straining to void, intermittent urinary flow, constipation and encopresis. An analysis was conducted to identify patients with febrile UTI and subsequently determine predictors of this condition. Univariate and multivariate analyses were performed. Overall, 326 patients (214 girls/112 boys) were evaluated. The mean age of the patients was 7.7±3.19 years (± standard deviation). The incidence of febrile UTI was 39.2%. Being female and infrequent voiding were factors significantly associated with febrile UTI, both in the univariate and multivariate analyses. These results show that being female and infrequent voiding constituted significant risk factors for a diagnosis of febrile UTI in these children.

Microbiome in the urinary system—a review

Directory of Open Access Journals (Sweden)

Jane Tang

2017-03-01

Full Text Available Urine was considered sterile in healthy individuals for many years, and the presence of bacteria signified urinary tract infection. With the development of Expanded Quantitative Urine Culture (EQUC and utilization of molecular techniques, the previous clinical dogma is no longer valid. Instead, healthy people harbor a considerable microbial community, or microbiota, in their urinary systems. Similar to other physiological niches where microbiota contribute to the health status of their hosts, recent studies demonstrated different microbial populations also play a crucial role in urinary health of individuals. Understanding urinary microbiome thus allows a more holistic approach in the diagnosis, treatment, and prevention of diseases and disorders in urinary system. This review article provides an overview of current findings in urinary microbiome and discusses some of the gaps for future research.

Selection on Coding and Regulatory Variation Maintains Individuality in Major Urinary Protein Scent Marks in Wild Mice.

Directory of Open Access Journals (Sweden)

Michael J Sheehan

2016-03-01

Full Text Available Recognition of individuals by scent is widespread across animal taxa. Though animals can often discriminate chemical blends based on many compounds, recent work shows that specific protein pheromones are necessary and sufficient for individual recognition via scent marks in mice. The genetic nature of individuality in scent marks (e.g. coding versus regulatory variation and the evolutionary processes that maintain diversity are poorly understood. The individual signatures in scent marks of house mice are the protein products of a group of highly similar paralogs in the major urinary protein (Mup gene family. Using the offspring of wild-caught mice, we examine individuality in the major urinary protein (MUP scent marks at the DNA, RNA and protein levels. We show that individuality arises through a combination of variation at amino acid coding sites and differential transcription of central Mup genes across individuals, and we identify eSNPs in promoters. There is no evidence of post-transcriptional processes influencing phenotypic diversity as transcripts accurately predict the relative abundance of proteins in urine samples. The match between transcripts and urine samples taken six months earlier also emphasizes that the proportional relationships across central MUP isoforms in urine is stable. Balancing selection maintains coding variants at moderate frequencies, though pheromone diversity appears limited by interactions with vomeronasal receptors. We find that differential transcription of the central Mup paralogs within and between individuals significantly increases the individuality of pheromone blends. Balancing selection on gene regulation allows for increased individuality via combinatorial diversity in a limited number of pheromones.

[Mechanisms of urinary tract sterility maintenance].

Science.gov (United States)

Okrągła, Emilia; Szychowska, Katarzyna; Wolska, Lidia

2014-06-02

Physiologically, urine and the urinary tract are maintained sterile because of physical and chemical properties of urine and the innate immune system's action. The urinary tract is constantly exposed to the invasion of microorganisms from the exterior environment, also because of the anatomical placement of the urethra, in the vicinity of the rectum. Particularly vulnerable to urinary tract infections (UTI) are women (an additional risk factor is pregnancy), but also the elderly and children. The main pathogens causing UTI are bacteria; in 70-95% of cases it is the bacterium Escherichia coli. Infections caused by viruses and fungi are less common and are associated with decreased immunity, pharmacotherapy, or some diseases. Bacteria have evolved a number of factors that facilitate the colonization of the urinary tract: the cover and cell membrane antigens O and K1, lipopolysaccharide (LPS), fimbriae, pile and cilia. On the other hand, the human organism has evolved mechanisms to hinder colonization of the urinary tract: mechanisms arising from the anatomical structure of the urinary tract, the physicochemical properties of the urine and the activity of the innate immune system, also known as non-specific, which isolates and destroys pathogens using immunological processes, and the mechanisms for release of antimicrobial substances such as Tamm-Horsfall protein, mucopolysaccharides, immunoglobulins IgA and IgG, lactoferrin, lipocalin, neutrophils, cytokines and antimicrobial peptides. This review aims to analyze the state of knowledge on the mechanisms to maintain the sterility of the urinary tract used by the human organism and bacterial virulence factors to facilitate the colonization of the urinary tract.

The OxyContin crisis: problematisation and responsibilisation strategies in addiction, pain, and general medicine journals.

Science.gov (United States)

Whelan, Emma; Asbridge, Mark

2013-09-01

OxyContin(®) (Purdue Pharma, L.P., Stamford, CT) is now widely regarded as a drug of abuse fueling a larger opioid health crisis. While coverage in the North American press about OxyContin overwhelmingly focused upon the problems of related crime and addiction/misuse and the perspectives of law enforcement officials and police, coverage in those fields of medicine most intimately concerned with OxyContin-pain medicine and addiction medicine-was more nuanced. In this article, we draw upon the constructivist social problems tradition and Hunt's theory of moral regulation in a qualitative analysis of 24 medical journal articles. We compare and contrast pain medicine and addiction medicine representations of the OxyContin problem, the agents responsible for it, and proposed solutions. While there are some significant differences, particularly concerning the nature of the problem and the agents responsible for it, both pain medicine and addiction medicine authors 'take responsibility' in ways that attempt to mitigate the potential appropriation of the issue by law enforcement and regulatory agencies. The responses of pain medicine and addiction medicine journal articles represent strategic moves to recapture lost credibility, to retain client populations and tools necessary to their jobs, and to claim a seat at the table in responding to the OxyContin crisis.

The AP diameter of the pelvis: a new criterion for continence in the exstrophy complex?

International Nuclear Information System (INIS)

Ait-Ameur, A.; Kalifa, G.; Adamsbaum, C.; Wakim, A.; Dubousset, J.

2001-01-01

Reconstructive surgery of bladder exstrophy remains a challenge. By using CT of the pelvis, we suggest a new pre- and post-operative investigative procedure to define the AP diameter (APD) as a predictive criterion for continence in this anomaly. Patients and methods: Three axial CT slices were selected in nine children with exstrophy who had undergone neonatal reconstructive surgery. The three levels selected were the first sacral plate, the mid acetabular plane and the superior pubic spine. We used combined slices to measure: circle APD = distance between the first sacral vertebra and the pubic symphysis. circle Pubic diastasis (PD) circle Three angles defined on the transverse plane of the first sacral vertebra - iliac wing angle, sacropubic angle and acetabular version. In exstrophy, the angles demonstrate opening of the iliac wings and the pubic ramus, and acetabular retroversion compared to controls. Comparisons between controls, continent and incontinent patients reveal that in continent patients, APD increases with growth and seems to be a predictive criterion for continence, independent of diastasis of the pubic symphysis. We believe that CT of the pelvis with measurements of the APD should be performed in all neonates with bladder exstrophy before reconstructive surgery and for better understanding of the malformation. The APD seems to be predictive and may be a major criterion for continence, independent of PD. (orig.)

2016-09-01

Ultrasound techniques are able to provide a fairly complete examination of the urinary system, achieving a high sensitivity in relevant-pathology detection, especially in the kidney, bladder and prostate. Early detection of pathologies such as tumors or urinary tract obstructions, sometimes even before their clinical manifestation, has improved their management and prognosis in many cases. This, added to its low cost and harmlessness, makes ultrasound ideal for early approaches and follow-up of a wide number of urinary system pathologies. In this article, the ultrasound characteristics of the main urinary system pathologies that can be diagnosed by this technique, are reviewed.

Science.gov (United States)

Kim, Hyun Hee; Chung, Mi Hae; Bin, Joong Hyun; Cho, Kyoung Soon; Lee, Juyoung

2018-01-01

Background Given that YKL-40 is a known marker of inflammation, we sought to determine its association with urinary tract infection (UTI) in febrile children. Methods In total, 44 children aged 0 to 24 months with febrile UTI and 35 age- and sex-matched controls with fever from other causes were enrolled in the study. ELISA was performed to determine the level of YKL-40 in urine collected from each child. Results The ratio of urinary YKL-40 to creatinine (Cr) was higher in the children with a UTI than in the controls (Purinary YKL-40/Cr ratio, 0.86 for pyuria, and 0.71 for positive nitrite on urinalysis. We applied a cut-off value of 125.23 pg/mg to urinary YKL-40/Cr for detecting UTI. Eight of nine children in the control group with pyuria had urinary YKL-40/Cr levels lower than 125.23 pg/mg, and the one child in the UTI group without pyuria or positive nitrite had a urinary YKL-40/Cr level greater than 125.23 pg/mg. Conclusions Determining the levels of urinary YKL-40/Cr may help identify true cases of UTI in febrile young children, especially when they have pyuria but not nitrite, or have neither pyuria nor nitrite in the urine.

Cost-Effectiveness of Including a Nurse Specialist in the Treatment of Urinary Incontinence in Primary Care in the Netherlands.

Directory of Open Access Journals (Sweden)

K M Holtzer-Goor

Full Text Available Incontinence is an important health problem. Effectively treating incontinence could lead to important health gains in patients and caregivers. Management of incontinence is currently suboptimal, especially in elderly patients. To optimise the provision of incontinence care a global optimum continence service specification (OCSS was developed. The current study evaluates the costs and effects of implementing this OCSS for community-dwelling patients older than 65 years with four or more chronic diseases in the Netherlands.A decision analytic model was developed comparing the current care pathway for urinary incontinence in the Netherlands with the pathway as described in the OCSS. The new care strategy was operationalised as the appointment of a continence nurse specialist (NS located with the general practitioner (GP. This was assumed to increase case detection and to include initial assessment and treatment by the NS. The analysis used a societal perspective, including medical costs, containment products (out-of-pocket and paid by insurer, home care, informal care, and implementation costs.With the new care strategy a QALY gain of 0.005 per patient is achieved while saving €402 per patient over a 3 year period from a societal perspective. In interpreting these findings it is important to realise that many patients are undetected, even in the new care situation (36%, or receive care for containment only. In both of these groups no health gains were achieved.Implementing the OCSS in the Netherlands by locating a NS in the GP practice is likely to reduce incontinence, improve quality of life, and reduce costs. Furthermore, the study also highlighted that various areas of the continence care process lack data, which would be valuable to collect through the introduction of the NS in a study setting.

The aim of the study was to evaluate the presence of urinary incontinence in patients with chronic degenerative spinal disease and to identify factors affecting the occurrence and changes in urinary incontinence after surgery. The group evaluated comprised 214 patients undergoing surgery for degenerative spinal disease at our department between January 1 and December 31, 2008. The patients were categorised according to the type of their degenerative disease (cervical disc herniation, lumbar disc herniation, spinal stenosis, spinal instability or olisthesis) and the spine level involved (cervical or lumbar spine). The symptoms of urinary incontinence included leakage of urine and non-obstructive chronic urinary retention developing in association with the manifestation of vertebrogenic disorder. Patients with diseases known to increase the risk of incontinence were not included in the study. Based on a retrospective analysis of the patients' clinical notes, the occurrence of urinary incontinence in each type of degenerative spinal disease was assessed. The effect of gender, age, body mass index (BMI), neurological status and spinal disease type on the development of incontinence was statistically evaluated. The efficacy of surgical treatment was assessed on the basis of the patients' subjective complaints at the first follow-up one month after surgery. The data were evaluated by the statistical programme InSTAT (analysis of variance ANOVA, t-test). All tests were two-sided; a 0.05 level of statistical significance was used. Of the 214 patients with degenerative spinal disease, 27 (12.6%) had urinary incontinence. A higher risk of developing incontinence was found in women (p = 0.008) and in patients with radicular weakness (p = 0.023). The patients with urinary incontinence had their BMI significantly lower than patients without this disorder (p = 0.019). Age had no effect. The differences in the occurrence of urinary incontinence amongst the different types of

The purpose of this article was to investigate whether the combination of urinary beta 2 microglobulin (urinary β 2 -MG) and procalcitonin (PCT) diagnosis could enhance the localization diagnostic precision of pediatric urinary tract infection comparing with single diagnosis. A study was conducted in the Nephrology Department of Wuhan women and children's health care centre. This study incorporated 85 participants, including 35 children who were diagnosed as upper urinary tract infection (UUTI) with the symptom of fever and 50 children who conducted lower urinary tract infection (LUTI). Levels of PCT and urinary β 2 -MG in both UUTI and LUTI patients were measured and compared. The level of PCT and β 2 -MG were both significantly higher in UUTI group compared with in LUTI group. AUC of urinary β 2 -MG ROC (sensitivity of 71.4%, specificity of 90.0%) was significantly smaller than that of PCT ROC (sensitivity of 77.1%, specificity of 96.0%) in the single diagnosis. Although in the combined diagnosis, the sensitivity and specificity increased to 88.6% and 98%, respectively. Both PCT and β 2 -MG could be used to localize the UTI. Introducing urinary β 2 -MG into PCT diagnosis could increase the sensitivity and specificity of UTI lesion diagnosis in clinical practice. © 2016 The Authors Journal of Clinical Laboratory Analysis Published by Wiley Periodicals, Inc.

Effects of diuretics on urinary proteins.

Science.gov (United States)

Li, Xundou

2015-01-01

Biomarker is the measurable change associated with a physiological or pathophysiological process. Unlike blood which has mechanisms to keep the internal environment homeostatic, urine is more likely to reflect changes of the body. As a result, urine is likely to be a better biomarker source than blood. However, since the urinary proteome is affected by many factors, including diuretics, careful evaluation of those effects is necessary if urinary proteomics is used for biomarker discovery. The human orthologs of most of these 14 proteins affected are stable in the healthy human urinary proteome, and 10 of them are reported as disease biomarkers. Thus, our results suggest that the effects of diuretics deserve more attention in future urinary protein biomarker studies. Moreover, the distinct effects of diuretics on the urinary proteome may provide clues to the mechanisms of diuretics.

Hiergeist, Andreas; Gessner, André

2017-03-01

The purpose of this review is to outline and evaluate the most recent literature on the role of the microbiome in urinary tract diseases. High throughput molecular DNA sequencing of bacterial 16S rRNA genes enabled the analysis of complex microbial communities inhabiting the human urinary tract. Several recent studies have identified bacterial taxa of the urinary microbiome to impact urinary tract diseases including interstitial cystitis, urgency urinary incontinence or calcium oxalate stone formation. Furthermore, treatment of urinary tract infections by antibiotics globally impacts community profiles of the intestinal microbiota and might indirectly influence human health. Alternative treatment options like application of probiotics for the treatment of urinary tract infections are currently under investigation. The urinary microbiome and its relationship to urinary tract diseases is currently under comprehensive investigation. Further studies are needed to shed light on the role of commensal microbiota for urinary tract infections.

Mungli Prakash

2010-10-01

Full Text Available Introduction: Peptide levels in urine are found to be decreased in renal failure. In the current study urinary peptide levels were determined in chronic renal failure (CRF patients. Method: 86 CRF patients and 80 healthy controls were selected for the study. Urinary proteins and peptide levels were determined by spectrophotometer based Lowry and Bradford methods. Urinary creatinine levels were determined by clinical chemistry analyzer. Results: There was significant decrease in urinary peptide levels in CRF patients and Urinary % peptides were significantly decreased in CRF patients as compared to healthy controls. Urinary % peptides correlated negatively with proteinuria. Conclusion: we have found decrease in urinary peptides and % urinary peptides in CRF patients and possibly measurement of % urinary peptides may possibly serve as better indicator in early detection of impairment in renal function.

Human alterations to nutrient cycles and herbivore communities are affecting global biodiversity dramatically. Ecological theory predicts these changes should be strongly counteractive: nutrient addition drives plant species loss through intensified competition for light, whereas herbivores prevent competitive exclusion by increasing ground-level light, particularly in productive systems. Here we use experimental data spanning a globally relevant range of conditions to test the hypothesis that herbaceous plant species losses caused by eutrophication may be offset by increased light availability due to herbivory. This experiment, replicated in 40 grasslands on 6 continents, demonstrates that nutrients and herbivores can serve as counteracting forces to control local plant diversity through light limitation, independent of site productivity, soil nitrogen, herbivore type and climate. Nutrient addition consistently reduced local diversity through light limitation, and herbivory rescued diversity at sites where it alleviated light limitation. Thus, species loss from anthropogenic eutrophication can be ameliorated in grasslands where herbivory increases ground-level light.

Understanding extinction drivers in a human-dominated world is necessary to preserve biodiversity. We provide an overview of Quaternary extinctions and compare mammalian extinction events on continents and islands after human arrival in system-specific prehistoric and historic contexts. We highlight the role of body size and life-history traits in these extinctions. We find a significant size-bias except for extinctions on small islands in historic times. Using phylogenetic regression and classification trees, we find that while life-history traits are poor predictors of historic extinctions, those associated with difficulty in responding quickly to perturbations, such as small litter size, are good predictors of prehistoric extinctions. Our results are consistent with the idea that prehistoric and historic extinctions form a single continuing event with the same likely primary driver, humans, but the diversity of impacts and affected faunas is much greater in historic extinctions. © 2016 The Author(s).

On the other hand, the human organism has evolved mechanisms to hinder colonization of the urinary tract: mechanisms arising from the anatomical structure of the urinary tract, the physicochemical properties of the urine and the activity of the innate immune system, also known as non-specific, which isolates and destroys pathogens using immunological processes, and the mechanisms for release of antimicrobial substances such as Tamm-Horsfall protein, mucopolysaccharides, immunoglobulins IgA and IgG, lactoferrin, lipocalin, neutrophils, cytokines and antimicrobial peptides. This review aims to analyze the state of knowledge on the mechanisms to maintain the sterility of the urinary tract used by the human organism and bacterial virulence factors to facilitate the colonization of the urinary tract.

The assessment of the urinary system is typically performed by ultrasound. Nevertheless, an ultrasound may be inconclusive in fetuses with renal diseases that result in anhydramnios or oligohydramnios. In such cases, and in other cases in which ultrasound is limited, further investigation with MR should be considered. In the following article, we will provide an overview of the most commonly encountered disorders of the urinary system and their appearance on fetal MR imaging. Fetal MR imaging can accurately diagnose a wide variety of urinary tract disorders and must be seen as a valuable complementary tool to ultrasound in the assessment of the urinary system, particularly in cases of inconclusive ultrasound findings
