    We describe the application and results of modified Young-Dees-Leadbetter bladder neck reconstruction after successful complete primary repair in the newborn period. The records of 34 patients referred for a continence procedure after successful exstrophy closure were extracted from an institutionally approved database. Patient characteristics and surgical outcomes were assessed. A total of 31 male and 3 female patients were identified, of whom 27 and 1, respectively, underwent osteotomy at initial closure. No patients attained urinary continence and so they were referred for a continence procedure. Nine patients did not have adequate bladder capacity for bladder neck repair (mean bladder capacity 63 ml, range 20 to 80). In those with suitable capacity mean capacity was 119 ml (range 85 to 180) and they underwent bladder neck reconstruction at a mean age of 4.9 years. Of the 25 patients who underwent bladder neck repair 14 (56%) were dry during the day and night, 5 (20%) were dry during the day but wet at night and 6 (24%) were totally incontinent. Pelvic osteotomies were performed at initial closure in 14 totally continent patients (100%) and in 4 (80%) with daytime continence but in no totally incontinent patients. All continent patients underwent hypospadias repair before age 1 year and none required ureteral reimplantation before bladder neck repair. A number of patients require bladder neck reconstruction to achieve continence after successful initial closure with complete primary repair. The modified Young-Dees-Leadbetter technique provides reasonable results with daytime and nighttime dryness attained by more than half of the patients.

    Full Text Available The success of the initial closure of the complex bladder-exstrophy remains a challenge in pediatric surgery. This study describes a personal experience of the causes of failure of the initial closure and operative morbidity during the surgical treatment of bladder-exstrophy complex. From April 2000 to March 2014, four patients aged 16 days to 7 years and 5 months underwent complex exstrophy-epispadias repair with pelvic osteotomies. There were three males and one female. Three of them had posterior pelvic osteotomy, one had anterior innominate osteotomy. Bladder Closure: Bladder closure was performed in three layers. Our first patient had initial bladder closure with polyglactin 4/0 (Vicryl ® 4/0, concerning the last three patients, initial bladder closure was performed with polydioxanone 4/0 (PDS ® 4/0. The bladder was repaired leaving the urethral stent and ureteral stents for full urinary drainage for three patients. In one case, only urethral stent was left, ureteral drainage was not possible, because stents sizes were more important than the ureteral diameter. Out of a total of four patients, initial bladder closure was completely achieved for three patients. At the immediate postoperative follow-up, two patients presented a complete disunion of the abdominal wall and bladder despite an appropriate postoperative care. The absorbable braided silk (polyglactin used for the bladder closure was considered as the main factor in the failure of the bladder closure. The second cause of failure of the initial bladder closure was the incomplete urine drainage, ureteral catheterisation was not possible because the catheters sizes were too large compared with the diameters of the ureters. The failure of the initial bladder-exstrophy closure may be reduced by a closure with an absorbable monofilament silk and efficient urine drainage via ureteral catheterisation.

    Functional anatomy of the bladder neck and proximal urethra has been studied extensively because of the belief that it is important for urinary continence. The aim of this study was to explore the limits of normality for pelvic floor ultrasound parameters of bladder neck and urethral mobility associated with stress urinary incontinence (SUI) and urodynamic stress incontinence (USI). A retrospective study was conducted on 589 women seen for urodynamic testing in a tertiary urogynaecology clinic. All women were assessed following a protocol including interview, clinical examination, flowmetry, urodynamic testing and 4D pelvic floor ultrasound. Volume data sets were analysed offline to assess for bladder neck descent (BND), urethral rotation and the retrovesical angle (RVA) on maximal Valsalva. After excluding women with previous incontinence or prolapse surgery, 429 datasets were available. SI was significantly associated with the RVA (p = 0.033) and BND (p = 0.036); USI was associated with urethral rotation (p = 0.021) and BND (p < 0.001). On multivariate logistic regression analysis, controlling for confounders including age, BMI, parity, previous hysterectomy and maximal urethral pressure, the association between SUI and BND remained significant (OR [per 10 mm] = 1.23; 95 % CI: 1.01 to 1.51; p = 0.043), as did the association between USI and BND (OR [per 10 mm] = 1.58; 95 % CI: 1.3 to 1.91; p < 0.001). ROC statistics for BND suggested a cut-off of 25 mm in describing the limit of normality. Measures of functional bladder neck anatomy are weakly associated with SUI and USI (with association between BND and USI being the strongest). It is suggested that a BND of 25 mm or higher be defined as abnormal ("hypermobile") on the basis of its association with USI.

    Primary bladder neck obstruction (PBNO) is a frequent under-investigated urological condition in which the bladder neck fails to open adequately during voiding. In the majority of cases no known etiological factor can be found. In this study we propose a new hypothesis to explain the origin of the disease in young male patients with no neurological disorders. We suggest a possible role of an unbalanced biomechanics of the pelvis on urethral sphincters activity and on functional bladder capacity. To support the proposed hypothesis, we present pilot gait analysis data of young male patients with primary bladder neck obstruction.

    The vesical orifice of the bladder neck contracture was viewed through the different optical systems. To observe the bladder neck contracture, the urethroscopy by the straight forward optical telescope and the cystoscopy by the retrograde optical telescope are useful. The bladder neck could be more accurately observed through the retrograde optical telescope. The bladder neck contracture was seen as an intravesical rising of the entire circumference of the rim of the bladder neck. Benign pros...

Materials and methods: Work basis included the analysis of treatment results of 1171 patients with BPH who carried complex examination, operative treatment and further supervision. The basic group was made up of 182 patients with BPH who developed bladder neck sclerosis in the postoperative period. The control group consisted of 200patients with BPH who did not develop the described pathology. clinico-anamnestic, laboratory methods and instrumental studies were used. Results: Disturbance of microcirculation in a bladder neck was considered to be a pathogenetic factor of sclerosis development as one of seri¬ous complications of operative treatment in case of BPH. The presence of microcirculatory disorders was confirmed by histological analysis. Inflammation in the bladder neck should be considered as an aggravating factor. Conclusion: The presence of microcirculatory disorders in the bladder neck in patients with BPH requires preoperative corrective therapy for prevention of sclerosis

    Full Text Available Abstract Objective To compare the function of the pelvic floor in primiparae before and during pregnancy with the status post partum concerning symptoms of incontinence, sphincter ruptures, bladder-neck mobility and the influence of the different modes of deliveries. Methods Questionnaire evaluating symptoms of urinary and anal incontinence in nulliparous women before and after delivery and correlating these symptoms with functional changes of the pelvic floor based on a careful gynaecologic examination as well as perineal and endoanal ultrasound. Results 112 women were included in our study and came for the first visit, 99 women returned for follow-up 6 months after childbirth. Stress and flatus incontinence significantly increased from before pregnancy (3 and 12% to after childbirth (21 and 28% in women with spontaneous delivery or vacuum extraction. No new symptoms occurred after c-section. There was no significant difference between the bladder neck position before and after delivery. The mobility of the bladder neck was significantly higher after vaginal delivery using a vacuum extraction compared to spontaneous delivery or c-section. The bladder neck in women with post partum urinary stress incontinence was significantly more mobile than in continent controls. The endoanal ultrasound detected seven occult sphincter defects without any correlation to symptoms of anal incontinence. Conclusion Several statistically significant changes of the pelvic floor after delivery were demonstrated. Spontaneous vaginal delivery or vacuum extraction increases the risk for stress or anal incontinence, delivery with vacuum extraction leads to higher bladder neck mobility and stress incontinent women have more mobile bladder necks than continent women.

    Bladder neck contracture is usually a complication of prostatectomy and the treatment of choice in such a condition should be endoscopic surgery. However, in a few patients the bladder neck may be completely obstructed preventing retrograde access into the bladder. A case is presented of complete bladder neck obstruction occurring after transurethral resection of prostate, which was treated after an access was provided by using transurethral Seldinger technique.

    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.

    Successful primary bladder closure of classic bladder exstrophy sets the stage for development of adequate bladder capacity and eventual voided continence. The postoperative pathway following primary bladder closure at the authors' institution is quantitatively and qualitatively detailed. Sixty-five consecutive newborns (47 male) undergoing primary closure of classic bladder exstrophy were identified and data were extracted relating to immediate postoperative care. Overall success rate was utilized to validate the pathway. Mean age at time of primary closure was 4.6 days and mean hospital stay was 35.8 days. Osteotomy was performed in 19 patients (mean age 8.8 days), and was not required in 39 infants (mean age 2.9 days). All patients were immobilized for 4 weeks. Tunneled epidural analgesia was employed in 61/65 patients. All patients had ureteral catheters and a suprapubic tube, along with a comprehensive antibiotic regimen. Postoperative total parenteral nutrition was commonly administered, and enteral feedings started around day 4.6. Our success rate of primary closure was 95.4%. A detailed and regimented plan for bladder drainage, immobilization, pain control, nutrition, antimicrobial prophylaxis, and adequate healing time is a cornerstone for the postoperative management of the primary closure of bladder exstrophy.

    Primary female bladder neck obstruction is a rare clinical condition characterized by the absence/incomplete bladder neck opening during the voiding phase of micturition. We present the cases of two women complaining dysuria, abdominal straining and sensation of incomplete bladder emptying. Videourodynamic evaluation was fundamental for a correct diagnosis. Videourodynamic evaluation showed a high detrusor pressure during emptying phase, partial use of abdominal strain, very low urine flow rate and significant postvoid residual; imaging showed a defect in the physiological funneling of the bladder neck, absent or incomplete. The first step therapy is represented by oral alpha-blockers and clean intermittent self-catheterization in case of high postvoid residual. Surgical operations, such as bladder neck incision and resection, represent the last option. In our experience, bladder neck obstruction is a rare condition in women and only a complete clinical evaluation associated with videourodynamic study can lead to an appropriate diagnosis and treatment.

    The aim of this study was to investigate the efficacy of the rectus abdominis myo-peritoneal flap (RAMP) technique for the closure and augmentation of small, non-elastic, non-compliant bladder exstrophies. The RAMP technique was used in three boys with bladder exstrophy who presented late with small, non-elastic, non-compliant bladder. The clinical outcome, imaging, cystoscopy, biochemical and microbiological studies were assessed during a follow-up of 36 months. Bladder closure and augmentation was achieved in all patients without any complications. There were no urinary tract infections, metabolic problems or electrolyte disturbances and the kidney function remained normal in all patients. Radiography confirmed intact function and anatomy of the urinary tract and cystoscopy showed complete coverage of the inner peritoneal layer of RAMP with uroepithelium. No stone formation or mucous production was detected. The RAMP technique is a good alternative for closing bladder exstrophies and achieves an increase in bladder capacity and compliance. The technique is indicated in the closure of large bladder defects, bladder exstrophies with small, inelastic, non-compliant bladder remnants and failed primary closures.

    Full Text Available ABSTRACTPurpose:To evaluate continence after radical prostatectomy in prostate cancer patients, in whom a new method of the bladder neck reconstruction (BNR using deep dorsal stitch was implemented (deep single stitch through all bladder layers directly dorsal to the bladder opening after “tennis racket” reconstruction and to provide justification for its use by means of anatomical study in cadavers.Material and Methods:Open radical retropubic prostatectomy was performed in 84 patients: 39 patients with a new BNR method used to improve continence and control group of 45 patients with standard “tennis racket” BNR. Median follow-up was 14 months in control group and 12 months in study group. Continence recovery was accessed early postoperatively and every 3 months thereafter. Anatomical study was performed on 2 male fresh cadavers reproducing two different BNR techniques to clarify any underlying continence related mechanisms.Results:Patients with new BNR achieved full continence significantly faster (p=0.041, but the continence rates after 12 months were similar between groups. The severity of incontinence up to month 9 was significantly reduced in BNR group. The anastomotic stricture rate was not affected. Applying new BNR to the cadaver model revealed effects on early continence, namely presence of proximal passive closure mechanism in area of bladder neck.Conclusions:Continence in patients with the new BNR method using deep dorsal stitch recovered significantly faster. Moreover, a reduced grade of residual incontinence was documented. The effect was non-significant at month 12 of follow-up, meaning that only early effect was present.

    To assess the long-term outcome of circumferential expanded PTFE (Gore-tex, WL Gore Associates, Scotland) bladder neck slings for achieving urethral continence in children with a neuropathic bladder. The records were reviewed of 19 children undergoing bladder reconstruction (most with a neuropathic bladder) who had a Gore-tex sling placed circumferentially at the bladder neck, over a 5-year period. Of these, seven had spina bifida; two each spinal dysraphism, surgery for anorectal anomalies and an idiopathic neuropathic bladder; five who developed a neuropathic bladder from other causes, and one born with bladder exstrophy. All children had an uncompliant bladder with a low urethral leak-point pressure on preoperative urodynamics. In all children conventional clean intermittent catheterization and pharmacotherapy had failed. Four had had previous augmentation surgery while 15 had concomitant bladder augmentation and formation of a Mitrofanoff stoma. The main outcome measure was achieving dryness. The original intention of the procedure was also to maintain urethral catheterization. Full details of the follow-up were available in 17 patients. Despite initial good short-term results, at a median follow up of 7 years, in 14 patients the sling had to be removed because of erosion, often with transient urethral leakage before the bladder neck subsequently closed. A bladder calculus was associated with each case of erosion except one. Although in the short term this technique had favourable results, it was not a useful technique in the long term.

    Full Text Available Residual urine volume is measured to diagnose various neurogenic and obstructive disorders of the urinary bladder. However, it is hypothesized that cystotomy closure using inverting patterns decreases intraluminal diameter of urinary bladder which consequently reduce residual bladder volume. This study aimed to investigate the ideal suturing style for cystotomy incision closure which would exert the least effect on residual bladder volume. The effect of various suturing styles on residual bladder volume was studied sonographically. Residual Bladder Volume (RBV was calculated by the formula, i.e. RBV=L×W× (DL+DT/2×0.625, where L=longitudinal diameter, W=transverse diameter, DL= depth at longitudinal diameter, DT=depth at transverse diameter. 24 healthy mongrel dogs were selected and randomly divided into four equal groups A, B, C and D (n=6. In groups A, B and C, the cystotomy incision was subsequently closed by two-layered appositional suturing pattern, two-layered inverting pattern and three layers (using a combination of appositional and inverting styles, respectively. Group-D remained as sham-operated Control. The results clearly showed that the three-layered closure technique using a combination of appositional and inverting patterns (Group-C, significantly reduced the bladder volume (P<0.01. Two-layered inverting patterns (Group B, also reduced the bladder volume but not up to a significant level, whereas, the appositional suturing technique (group-A exerted the least effect on residual bladder volume. Conclusively, it was inferred that a two-layered appositional suturing pattern should be preferred for closure of cystotomy incision to avoid significant changes in residual bladder volume.

    Full Text Available Radical prostatectomy is a «gold standard» for treatment of the patients with a localized prostate cancer. Urinary incontinence is one of the two most common complications of this operation. In this article we report a study aimed to compare the efficacy parameters linked to postoperative continence in 39 patients with new technique for reconstruction of the bladder neck during the radical prostatectomy using a deep suture of the bladder wall dorsally to the neck aperture with 45 patients in control group with a standard type of reconstruction in the form of tennis racket. According to the results, application of the new technique leads to a significant improvement in continence during the first 6 months after the operation with no difference among groups during follow-up later on. Given the results of the anatomical study, the efficacy of the new method of reconstruction is linked to passive closure mechanism created in the area of the bladder neck.

    Full Text Available Introduction With improved understanding of the precise anatomy, surgical techniques during robot-assisted radical prostatectomy (RARP have been refined, with the aim of improving functional outcomes without compromising oncological adequacy and results. Nevertheless, postoperative urinary incontinence remains a frustrating side-effect. Anatomically, bladder neck (BN serves as an internal sphincter. The longitudinal fibres of BN may be identified and isolated with a meticulous dissection at the prostato-vesical junction, contributing to earlier return of urinary continence. The purpose of this video is to show an anatomical athermal dissection of BN during RARP.Materials and Methods After incision of endopelvic fascia and anterior defatting, the morphology of prostate not only laterally, but also at the level of bladder-prostatic junction is well visualized. With an athermal dissection of the plane between prostate and bladder we can minimize the traumatic effects on the longitudinal fibres of BN. A cold section of the preserved BN permits the complete preservation of integrity of this sphincteric structure.Results With this technique we preserve the longitudinal fibres of BN, allowing the sparing of the sphincteric mechanism of BN. The finding of a difficult athermal dissection of these plans may make you suspect the presence of an infiltration, suggesting to sacrifice BN in order to avoid a positive surgical margin. In our series no increase of PSM has been recorded using this technique.Conclusions This surgical technique preserving the natural BN mechanism appears to improve urinary continence, allowing at the same time an easy identification of a neoplastic infiltration.

    Background Pressure-flow study combined with cystourethroscopy were used as the major method to define female bladder neck obstruction in China.However,the definition of urodynamics for female bladder outlet obstruction (BOO) is not clear so far.Video-urodynamic study (VUDS) would provide more information to define the female BOO,but it is not used commonly due to the limitation of video-urodynamic equipment in China.We attempted to find a better way for diagnosis of female BOO by performing VUDS.Methods VUDS and cystourethroscopy were performed in 38 women with signs and symptoms of difficult voiding from March 2008 to April 2010 in Beijing Chao-Yang Hospital.Bladder neck obstruction was defined by radiological evidence of narrowing bladder neck,voiding pressure greater than 20 cmH2O and maximum flow rate (Qmax) less than 12 ml/s.Transurethral incision of bladder neck was then performed on those patients.Follow-up examination (Qmax and residual urine) was recorded 3 months after operation.Results The mean time from its onset to diagnosis was (18.1±9.1) months in 38 patients.Average patient age was 36.1 years (range from 19 to 79 years).The mean Qmax was (10.6±4.7) ml/s and residual urine was (81.5±42.4) ml.Three out of 38 patients had obvious distal urethral stricture,eight of them suffered from definitely bladder neck contracture and the remaining 27 patients did not show obvious abnormalities measured by cystourethroscopy examination.For the 35 patients without urethral stricture,the most frequent findings of VUDS were high-voiding pressure plus low-flow rate and narrow bladder neck during voiding on simultaneous fluoroscopy examination.With video-urodynamics definition,32 patients were diagnosed as bladder neck obstruction with mean Qmax of (10.8±3.7) ml/s,residual urine of (76.9±32.7) ml and detrusor pressure at maximum flow (PdetQmax) of (50.7±19.1) cmH2O.Other three patients were suffered from detrusor hypocontractility.All 32 patients including eight

    Full Text Available Introduction and aim: The video-urodynamics study is the principal exam to establish a possible primary bladder neck obstruction (PBNO condition. While trans-rectal ultrasonography plays an important role in the evaluation of the low urinary tract symptoms (LUTS and the severity of bladder outlet obstruction (BOO in men, the use of the transvaginal ultrasound (TVUS in women with symptoms suggesting BOO remains unclear. We tried to check the utility of the TVUS in women with PBNO condition. Material and methods: We selected female patients which presented BOO without pelvic organ prolapse (POP. According to the data of the video-urodynamic exam we selected the patients with the suspicion of PBNO. A TVUS in basal and during micturition was performed before and after surgery. Results: TVUS showed a closed bladder neck bladder in basal condition and during micturition similarly to the fluoroscopic image during video-urodynamics. The mean distance from bladder neck to the vaginal mucosa resulted 1.3 cm in this patients. Conclusions: TVUS results worthy in the evaluation of patients with PBNO before and after surgery.

    Conclusions: BNC was identified in 1.6% of patients in our series following RARP. Intraoperative blood loss was a significant risk factor for BNC. In 20% of BNC patients a migrated foreign body was noted at vesicourethral anastomosis. Primary management of patients with BNC following RARP should be bladder neck incision and self CIC regimen.

    Objective: Ho:YAG laser had been used to treat the common diseases of urinary system such as bladder cancer and benign prostatic hyperplasia in our hospital. This study is to assess the efficacy and safety of transurethral Ho:YAG-laser resection to treat the urethral stricture and bladder neck contracture. Methods: From May 1997 to August 2004, 26 cases of urethral stricture and 33 cases of bladder neck contracture were treated by transurethral Ho:YAG-laser resection. These patients were followed up at regular intervals after operation. The uroflow rate of these patients was detected before and one-month after operation. The blood loss and the energy consumption of holmium-laser during the operation as well as the complications and curative effect after operation were observed. Results: The therapeutic effects were considered successful, with less bleeding and no severe complications. The Qmax of one month postoperation increased obviously than that of preoperation. Of the 59 cases, restenosis appeared in 11 cases (19%) with the symptoms of dysuria and weak urinary stream in 3-24 months respectively. Conclusions: The Ho:YAG-laser demonstrated good effect to treat the obstructive diseases of lower urinary tract such as urethral stricture and bladder neck contracture. It was safe, minimal invasive and easy to operate.

    The primary bladder neck obstruction (PBNO) has been recognized in 41-45% of young men suffering from a chronic lower urinary tract symptom (LUTS). Few studies are published in the literature about the use of laser devices in the surgical treatment of PBNO and none about the use of Thulium laser. The aim of our study is to report the results of our follow-up in the endoscopic treatment of PBNO with Thulium laser. From January 2012 to January 2015, we treated 214 patients using Thulium laser for primary bladder neck sclerosis. All patients had symptoms suggestive of LUTS or prostatism: filling or irritative symptoms and voiding or obstructive symptoms. In 157 patients, the incision was performed unilaterally at 7 o'clock of the bladder neck. In 57 cases, bilateral incision was performed at 5 and 7 o' clock without vaporizing the tissue between the two incisions. We chose to make the incision bilaterally in cases wherein a single incision was not enough to solve the obstruction from the bladder neck and prevent a recurrence. Bladder irrigation was used overnight in all cases, and the catheter was removed after 24 hours. One hundred ninety-six patients enrolled completed 1-year follow-up: 157 patients underwent unilaterally incision and 39 bilateral incision. In 179 cases (91.3%), there was unchanged antegrade ejaculation, while reduced semen volume was reported by 14 men (7.1%) and retrograde ejaculation by only 3 (1.5%), but these patients underwent bilateral incision. The quality of orgasm and sexual satisfaction was not permanently changed by the operation. In patients with PBNO, it is possible to perform endoscopic treatment with Thulium laser that we think is an effective and safe procedure, not affecting sexual functioning and particularly retrograde ejaculation.

    Full Text Available ObjectiveSuperficial bladder neck incision (SBNI is controversial at young age, with retrograde ejaculation after puberty as main concern. The aim of the study is to investigate the long-term effect of SBNI on ejaculation and incontinence in boys with primary and secondary bladder neck obstruction (BNO.Materials and methodsIn boys with infravesical obstruction, SBNI was performed in case of a persistent BNO after earlier desobstruction or in case of primary severely obstructive bladder neck. SBNI was performed with a diathermy hook, always superficially (2–3 mm and unilaterally at 7 O’clock. Males that had SBNI during childhood after posterior urethral valve incision or relief of other obstruction between 1986 and 2003 were included. Evaluation was done by International Continence Society male sex questionnaire, International Prostate Symptom Score, developmental International Consultation Modular Questionnaire on Urinary Incontinence, frequency volume chart, and uroflowmetry.ResultsOf 79 traceable patients, 40 (50.6% participated. Of these, 37 (92.5% completed all questionnaires and 28 (70% performed uroflowmetry. Median age at SBNI was 4.7 years [interquartile range (IQR 0.6–8.5] and was 19.6 years (IQR 17.3–20.9 at follow-up. All men had antegrade ejaculation, 4/37 (10.8% reported possibly reduced ejaculatory volume. Eight (22% had moderate lower urinary tract symptoms and two (5.4% had moderate incontinence. Median maximum flow rate was 30.1 mL/s (IQR 24.4–42.6.ConclusionSBNI in boys with severe infravesical obstruction can be done safely with preservation of antegrade ejaculation and no additional lower urinary tract dysfunction.

    Raoultella planticola is a Gram-negative, non-motile, aerobic bacillus. It is an environmental bacteria found in soil and water, and a very rare cause of local or systemic infection in humans. Although some adult cases of R. planticola infection have been reported, childhood local or systemic infection caused by R. planticola is very rare. Reported herein is a rare case of acute cystitis due to R. planticola in a 16-month-old boy with rhabdomyosarcoma of the bladder neck, and a review of the literature.

    We report on a negative outcome after implantation of a magnetic urethral closure device, consisting of one part screwed into the pubic bone and one part as a vaginal cone, for the treatment of urinary stress incontinence grade III. Continence was never achieved for the patient. The urethra narrowed over time due to erosion and scarring and the patient started intermittent catheterization, because spontaneous micturition was not possible. The magnet was broken, the bladder neck was eroded, several fragments were found in the bladder, and numerous fragments were scattered throughout the small pelvis. Surgery consisted of removing most of the fragments, followed by bladder neck closure and suprapubic diversion.

    Hem-o-lok clips are widely used during robot-assisted and laparoscopic radical prostatectomy to control the lateral pedicles. There are a few reports of hem-o-lok clip migration into the bladder or vesico-urethral anastomosis and only four cases of hem-o-lok clip migration resulting into bladder neck contracture. Herein, we describe the first case, to our knowledge, of hem-o-lok clip migration leading to severe bladder neck contracture and subsequent stress urinary incontinence. A 62-year-old Caucasian man underwent robot-assisted laparoscopic radical prostatectomy for a T1c Gleason 8 prostate cancer. One month after surgery the patient was fully continent; however, three months later, he presented with acute urinary retention requiring suprapubic drainage. Urethroscopy showed a hem-o-lok clip strongly attached to the area between the vesico-urethral anastomosis and the urethral sphincter and a severe bladder neck contracture behind it. Following cold-knife urethral incision and clip removal, the bladder neck contracture was widely resected. At 3-month follow-up, the patient voided spontaneously with a peak flow rate of 9.5 ml/sec and absence of post-void residual urine, but leaked 240 ml urine at the 24-hour pad test. To date, at 1-year follow-up, his voiding situation remains unchanged. The present report provides further evidence for the risk of hem-o-lok clip migration causing bladder neck contracture, and is the first to demonstrate the potential of such complication to result into stress urinary incontinence.

    Full Text Available Spina bifida and myelodysplasia are associated with neurogenic abnormalities of the bladder and bowel function. All children with myelodysplasia require an evaluation of their urinary tract with ultrasound and urodynamics to confirm normal bladder and kidney function. Patients with anatomical and functional abnormalities require treatment, the mainstay being intermittent catheterization and anticholinergic medication. The treatment goals for patients with a neurogenic bladder are the preservation of the upper urinary tract, bladder and bowel continence, independence, autonomy, and facilitation of self-esteem. A minority of children will not respond to conservative therapy and will ultimately require surgical intervention. This review will discuss the surgical options for bladder augmentation, bladder neck reconstruction and closure, as well as the methods for the creation of continent catheterizable stomas. The timing, indications, and description for each procedure will be addressed. Finally, the antegrade continence enema procedure will be described for the management of refractory fecal incontinence.

    Several techniques have been introduced to improve early postoperative continence.In this study,we evaluated the impact of bladder neck (vesicourethral anastomosis) suspension on the outcome of extraperitoneal endoscopic radical prostatectomy (EERPE).In this research,a total of 180 patients underwent EERPE.Group 1 included patients who underwent nerve-sparing EERPE (nsEERPE) (n=45),and Group 2 included patients who underwent nsEERPE with bladder neck suspension (BNS,n=45).Groups 3 (n=45) and 4 (n=45) included patients who received EERPE and EERPE with BNS,respectively.Patients were randomly assigned to receive BNS with their nsEERPE or EERPE procedure.Perioperative parameters were recorded,and continence was evaluated by determining the number and weight of absorbent pads (pad weighing test) on the second day after catheter removal and by a questionnaire 3 months postoperatively.Two days after catheter removal,11.1% of Group 1,11.1% of Group 2,4.4% of Group 3 and 8.9% of Group 4 were continent.The average urine loss was 80.4,70.1,325.0 and 291.3 g for the each of these groups,respectively.At 3 months,76.5% of Group 1 and 81.3% of Group 2 were continent.The continence figures for Group 3 and 4 were 48.5% and 43.8%,respectively.Similar overall rates were observed in all groups.In conclusion,although there are controversial reports in the literature,early continence was never observed to be significantly higher in the BNS groups when compared with the non-BNS groups,regardless of the EERPE technique performed.

  16. Bladder exstrophy: An overview of the surgical management

    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.

    To identify and characterize possible structural specialisations in the wall of the lower urinary tract (LUT) in the region of the bladder urethral junction (BUJ), with the specific objective of identifying regional variations in sensory nerve fibres and interstitial cells (ICs). The bladder base and urethra was removed from five male guinea pigs killed by cervical dislocation. Tissue pieces were incubated in Krebs' solution at 36 degrees C, gassed with 95% O(2) and 5% CO(2), fixed in 4% paraformaldehyde and processed for immunohistochemistry. The nonspecific marker vimentin and the general neuronal marker protein gene product (PGP) 9.5 were used to identify ICs and nerve fibres, respectively. Specific antibody binding was visualized using the appropriate secondary antibodies. The wall of the LUT in the region immediately between the bladder base and the urethra, the BUJ, differed in its cellular composition relative to the adjacent areas. PGP-positive (PGP(+)) nerve fibres, presumptive afferent fibres, lay within the urothelium running between the epithelial cells. There were two general nerve patterns: branching fibres with no varicosities, and complex fibres with varicosities. Fibre collaterals with varicosities exited the urothelium and occupied the space under the urothelium adjacent to the layer of suburothelial ICs. The latter, lamina propria and around the muscle bundles were identified using vimentin (vim(+)). In the base a few vim(+) cells were also PGP(+). In the region of the BUJ there was a decrease in the amount of smooth muscle. In this region, below the lamina propria, there was an area densely populated with vim(+)/PGP(+) ICs. Nerve fibres ran between the cells in this region. These structural specialisations within the urothelium and deeper layers of the BUJ suggest that they might be associated with specific functions. The localized highly branched network of the putative afferent nerves suggests the presence of a local axonal reflexes involving

    Full Text Available Objective: To examine the efficacy of a two staged treating strategy with the use of a non-permanent urethral ALLIUM® stent for the management of recurrent bladder neck stenosis and subsequently the use of an artificial sphincter AUS800® by AMS for the management of the incontinence. Materials and Methods: We progressively identified patients eligible for the study creating a population of cases with recurrent bladder neck stenosis and concomitant incontinence occurring after the last intervention for the stenosis. Efficacy for the treatment of the stenosis was defined as no recurrence both prior and post to the sphincter placement and efficacy for the treatment of the incontinence was defined as continence (0-1pads after the sphincter placement. Results and Limitations: 14 white males with a mean age of 66.21, ranging from 59 to 73 years consisted the population of the study. All patients had severe stress incontinence following the last transurethral resection. The efficacy of the treatment of the bladder neck stenosis was 93% (13/14 while the efficacy for the treatment of the incontinence was 100%. A single patient had a recurrent bladder neck stenosis after the artificial sphincter placement and was treated with transurethral resection using a long pediatric 13 F resectoscope at 12 months. Our limitations is the absence of a control group and the small number of patients enrolled, with a relatively short time of follow up. Conclusions: In our series we propose the use of a non-permanent urethral ALLIUM® stent for 6 months in order to control the growth of fibrotic scar tissue, a further 6 months follow up for recurrence, and then placement of an artificial sphincter. The results are very promising both on stabilizing the vesicourethral stenosis, and on patient safety and tolerability.

  20. Severe lower urinary tract symptoms due to anteriorly located midline prostatic cyst arising from the bladder neck in a young male: case report

    Full Text Available ABSTRACT CONTEXT: Prostatic cysts are uncommon. These cysts are usually asymptomatic and are diagnosed incidentally during ultrasonographic examination. On rare occasions, they may cause drastic symptoms. CASE REPORT: We report on a case of severely symptomatic anteriorly located prostatic cyst arising from the bladder neck in a 30-year-old man presenting with lower urinary tract symptoms, without clinical evidence of benign prostatic hyperplasia. Transrectal ultrasonography (TRUS, computed tomography (CT and cystourethroscopy demonstrated a projecting prostatic cyst that occupied the bladder neck at the precise twelve o'clock position. It was acting as a ball-valve, such that it obstructed the bladder outlet. Transurethral unroofing of the cyst was performed and the patient's obstructive symptoms were successfully resolved. Histopathological examination indicated a retention cyst. CONCLUSIONS: It should be borne in mind that midline prostate cysts can be a reason for bladder outlet obstruction in a young male. Such patients may have tremendous improvement in symptoms through transurethral unroofing of the cyst wall.

    Recent articles document successful classic bladder exstrophy (CBE) closure without osteotomy. Still, many patients require osteotomy if they have a large bladder template and pubic diastasis, or non-malleable pelvis. To understand the indications and outcomes of bladder closure with and without pelvic osteotomy in patients younger than 1 month of age. An institutional database of 1217 exstrophy-epispadias patients was reviewed for CBE patients closed at the authors' institution within the first month of life. Patient demographics, closure history, pubic diastasis distance, bladder capacity, and outcomes were recorded and compared using chi-square tests between osteotomy and non-osteotomy patients. Failure was defined as bladder dehiscence, prolapse, vesicocutaneous fistula, or bladder outlet obstruction requiring reoperation. Bladder capacity >100 mL was deemed sufficient for bladder neck reconstruction (BNR). One hundred CBE patients were included for analysis: 38 closed with osteotomy (26 male, 12 female), and 62 closed without osteotomy (42 male, 20 female). There were four failed closures in the osteotomy group (2 dehiscence, 2 prolapse) and four failed closures in the non-osteotomy group (2 dehiscence, 2 prolapse). This corresponded to statistically equivalent rates of failure between the osteotomy and non-osteotomy groups (10.5% vs. 6.5%, p = 0.466). There was no statistically significant difference between the groups' ability to achieve bladder capacity sufficient for BNR (82% vs. 71%, p = 0.234). A successful primary bladder closure, regardless of the use of osteotomy, has been shown to be the single most important predictor of eventual continence. Because of the complexity of exstrophy manifestations, a multidisciplinary team approach is of the utmost importance. Based on our institutional experience, closure without osteotomy is considered when patients are osteotomy in patients considered suitable for closure by both the pediatric urologist and

    Bladder neck contracture (BNC) after GreenLight laser photoselective vaporization (PVP) of benign prostatic hyperplasia is a common complication. In the present study, data of patients received 80 or 180 W PVP were collected. Perioperative parameters, including applied energy, irradiation time, catheter removal time, and hospital stay, were recorded. Postoperative parameters, including maximum urinary flow rate, International Prostate Symptom Score, post-void residual volume, and incidences of BNC, were recorded at 3 and 12 months after operations. Bladder neck tissues were taken at 3 months after operations for immunohistochemical staining and western blot analysis to examine the expressions of collagen I, matrix metalloproteinase-3 (MMP-3), and transforming growth factor-β (TGF-β). Sample size of patients was calculated with a power of 80 %. Chi-square test and one-way analysis of variance were performed as statistical methods. Three hundred twenty-six patients who received potassium titanyl phosphate (KTP) laser and 256 who received X-ray photoelectron spectroscopy (XPS) laser entered into the study. Perioperative parameters were comparable, except for shorter irradiation time in 180 W group (P = 0.032). Postoperative parameters were also similar, except for higher incidence of BNC in 80 W group at 3 months after operations (P = 0.022). Immunohistochemical staining and western blot analysis showed higher expressions of collagen I, MMP-3, and TGF-β in 80 W group than in 180 W group. In conclusion, 80 W GreenLight laser showed a comparable efficacy with 180-W laser in PVP but showed a higher incidence of BNC in short term, which might be the result of up-regulated fibrotic factors in bladder neck triggered by lasers.

    We evaluated the current application of Duckett paraexstrophy skin flaps for bladder exstrophy reconstruction. We reviewed the records of cases of classic exstrophy treated at our institution between September 1993 and March 2007. A total of 21 patients were identified in whom modified Duckett paraexstrophy skin flaps were used in bladder closure at our institution. Another 12 patients were referred during the same time after closure with complications with flap use. Of the 21 patients who underwent closure at our institution with our modified version of the Duckett flaps 1 (4%) had a complication, that is urethral stricture. This responded to internal urethrotomy and daily intermittent catheterization for 4 months, and the stricture stabilized. Four of the 12 referred patients responded to multiple urethral dilations, 3 underwent open repair with a buccal graft, 2 received a full-thickness skin graft and 3 underwent internal urethrotomy with daily intermittent catheterization for 4 months. Of our 21 patients with internal treatment 14 underwent bladder neck repair, 5 underwent epispadias repair and 2 were awaiting further reconstruction. Six of the 12 referred patients underwent bladder neck repair, 4 underwent epispadias repair and 2 were awaiting further reconstruction. By modifying our version of the Duckett paraexstrophy skin flaps we have lowered our complication rate significantly. While overall use of these flaps has continued to decrease, when they are required, these modifications help avoid complicating strictures and their sequelae in the bladder and upper urinary tract.

    Dystrophic calcification can be defined as a calcification that occurs in degenerated or necrotic tissue. It is associated with multiple clinical conditions, such as collagen vascular diseases. It involves the deposition of calcium in soft tissues despite no generalized disturbance in the calcium or phosphorus metabolism, and this is often seen at sites of previous inflammation or damage. Potassium-titanyl phosphate (KTP) laser vaporization of the prostate is safe and relatively bloodless procedure that results in a shorter catheterization, immediate symptomatic improvement, and less severe postoperative irritative symptoms. However, longer follow-up studies or reports about complications are lacking. Here in we report a case of dystrophic calcification and stone formation on the entire bladder neck after performing KTP laser vaporization of benign prostate hyperplasia. That was treated by lithotripsy and transurethral resection.

    A retrospective analysis was performed on 34 female patients who underwent corrective surgery for stress urinary incontinence over a 4-year period at the Toa Payoh Hospital. These patients were offered surgery only after an adequate trial of medical therapy, pelvic floor exercises and weight reduction. Bladder neck suspension operations were performed via the Burch, Stamey and modified Pereyra techniques. Towards the later part of this study, endoscopic injection of Collagen was performed as a salvage procedure in 2 patients. The Burch colposuspension gave uniformly good results, with all patients being completely dry. Seventy percent and sixty percent complete continence were achieved via the modified Pereyra and Stamey techniques respectively. Three patients required additional surgical procedures. Using these techniques, the overall results showed that 27 patients (79.4%) had complete urinary continence following surgery, while the remaining 7 patients (20.6%) experienced significant improvement of symptoms.

    Purpose: To identify an anatomic structure predictive for acute (AUT) and late (LUT) urinary toxicity in patients with prostate cancer treated with low-dose-rate brachytherapy (LDR) with or without external beam radiation therapy (EBRT). Methods and Materials: From July 2002 to January 2013, 927 patients with prostate cancer (median age, 66 years) underwent LDR brachytherapy with Iodine 125 (n=753) or Palladium 103 (n=174) as definitive treatment (n=478) and as a boost (n=449) followed by supplemental EBRT (median dose, 50.4 Gy). Structures contoured on the computed tomographic (CT) scan on day 0 after implantation included prostate, urethra, bladder, and the bladder neck, defined as 5 mm around the urethra between the catheter balloon and the prostatic urethra. AUT and LUT were assessed with the Common Terminology Criteria for Adverse Events, version4. Clinical and dosimetric factors associated with AUT and LUT were analyzed with Cox regression and receiver operating characteristic analysis to calculate area under the receiver operator curve (ROC) (AUC). Results: Grade ≥2 AUT and grade ≥2 LUT occurred in 520 patients (56%) and 154 patients (20%), respectively. No grade 4 toxicities were observed. Bladder neck D2cc retained a significant association with AUT (hazard ratio [HR], 1.03; 95% confidence interval [CI], 1.03-1.04; P<.0001) and LUT (HR, 1.01; 95% CI, 1.00-1.03; P=.014) on multivariable analysis. In a comparison of bladder neck with the standard dosimetric variables by use of ROC analysis (prostate V100 >90%, D90 >100%, V150 >60%, urethra D20 >130%), bladder neck D2cc >50% was shown to have the strongest prognostic power for AUT (AUC, 0.697; P<.0001) and LUT (AUC, 0.620; P<.001). Conclusions: Bladder neck D2cc >50% was the strongest predictor for grade ≥2 AUT and LUT in patients treated with LDR brachytherapy. These data support inclusion of bladder neck constraints into brachytherapy planning to decrease urinary toxicity.

    Many changes have occurred in the treatment of bladder exstrophy over the last few years and several repairs are now offered, but there is a lack of long-term follow-up data. The purpose of this study was to evaluate long-term outcomes in a select group of female patients in whom modern staged repair was undertaken. From an institutionally approved database 41 patients were identified. All had undergone primary bladder exstrophy closure in 1988-2005, at a mean age of 2 months (range 4h to 3 months), with or without an osteotomy by a single surgeon, and all were followed up for a minimum of 5 years. Twelve patients underwent osteotomy at the time of primary closure. Eight had a classic transverse innominate and vertical iliac osteotomy, and four a transverse innominate only. Mean age at the time of bladder neck repair (BNR) was 4.2 years (39-65 months). Mean measured bladder capacity under gravity cystograms at the time of repair was 109 cc (80-179 cc). Thirty patients (74%) were continent day and night, and voiding per urethra without augmentation or intermittent catheterization. Social continence, defined as dry for more than 3h during the day but damp at night, was found in a further four cases (10%). Seven patients are completely incontinent with dry intervals of less than 1h day and night. The mean time to daytime continence was 12 months (4-16 months) and to night-time continence was 19 months (10-28 months). Patients with a mean capacity greater than 100 cc had better outcomes. Six of the 30 patients achieved dryness after primary closure only, and all six had transverse innominate and vertical iliac osteotomy at the time of primary closure. Female classic exstrophy patients with a good template who develop adequate capacity after a successful primary closure can achieve acceptable continence without bladder augmentation and intermittent catheterization. A select group will develop continence with closure alone without the need for bladder neck repair.

    ABSTRACT Purpose: To determine risk factors of postoperative urethral stricture (US) and vesical neck contracture (BNC) after transurethral resection of prostate (TURP) from perioperative parameters. Materials and Methods: 373 patients underwent TURP in a Chinese center for lower urinary tract symptoms suggestive of benign prostatic obstruction (LUTS/BPO), with their perioperative and follow-up clinical data being collected. Univariate analyses were used to determine variables which had correlation with the incidence of US and BNC before logistic regression being applied to find out independent risk factors. Results: The median follow-up was 29.3 months with the incidence of US and BNC being 7.8% and 5.4% respectively. Resection speed, reduction in hemoglobin (ΔHb) and hematocrit (ΔHCT) levels, incidence of urethral mucosa rupture, re-catheterization and continuous infection had significant correlation with US, while PSA level, storage score, total prostate volume (TPV), transitional zone volume (TZV), transitional zone index (TZI), resection time and resected gland weight had significant correlation with BNC. Lower resection speed (OR=0.48), urethral mucosa rupture (OR=2.44) and continuous infection (OR=1.49) as well as higher storage score (OR=2.51) and lower TPV (OR=0.15) were found to be the independent risk factors of US and BNC respectively. Conclusions: Lower resection speed, intraoperative urethral mucosa rupture and postoperative continuous infection were associated with a higher risk of US while severer storage phase symptom and smaller prostate size were associated with a higher risk of BNC after TURP.

    A long term, retrospective study was performed aiming to outline a critical comparison concerning the efficacy, safety and durability of the bipolar plasma vaporization (BPV), standard monopolar transurethral resection (TUR) and "cold-knife" "star" transurethral incision (TUI) in secondary bladder neck sclerosis (BNS) cases. Of the 126 patients included in the trial based on maximum flow rate (Qmax) below 10 mL/s and International Prostate Symptom Score (IPSS) over 19, classical resection was performed in 46 cases, "cold-knife" TUI in 37 cases and bipolar vaporization in 43 patients. The evaluation protocol comprised IPSS, QoL (quality of life) score, Qmax and PVR (post-voiding residual urinary volume) assessment performed at 1, 3, 6, 12, 18 and 24 months after the initial intervention. Significant intraoperative complications (capsular perforation - 8.7%; bleeding - 4.3%) occurred secondary to monopolar resection. "Star" TUI was the fastest technique, followed by plasma-button vaporization (7.2 and 11.4 versus 16.5 minutes). BPV and TUI patients benefitted from the shortest catheterization periods (0.75 and 1 versus 2.0 days) and hospital stays (1.0 and 1.25 versus 2.0 days). Immediate postoperative adverse events consisted of hematuria (6.5% of the TUR cases) and acute urinary retention (8.1% of the TUI group). Significantly higher long term BNS recurrence rates requiring re-treatment were established in the TUI (18.7%) and TUR (12.8%) series by comparison to BPV (5.4%). Among patients that completed the follow-up protocol, equivalent IPSS, QoL, Qmax and PVR features were determined in the 3 study arms. The plasma vaporization approach was confirmed as a successful match to conventional TUR and "cold-knife" TUI in terms of surgical safety profile, postoperative recovery, therapeutic durability and urodynamic and symptom score parameters.

    Full Text Available Background: Role of pelvic osteotomy in surgical management of bladder exstrophy is controversial But pelvic rim closure importantly. Bulking agents have been used for perineal and pelvic dysfunction in adults. In this study, bladder extrophy repair was performed without pubic closure And bulking agent injections were used as the strut of anterior pelvis for prevention of Organ prolapse and other functions in this series. Patients and Methods: During the period 2008-2012, twenty-five exstrophy-epispadias complex patients with a mean age of 14 months underwent surgical reconstruction. Rectus abdominis Muscle was detached from the superior pubis and sutured to each other in the midline and Re-anchored at the pubis and 8-9 month later urethra was constructed and placed between prineal muscles. Bladder neck repair and intersyphyseal reconstruction was done With bulking agents one year after primary bladder closure when in our series bladder Prolapse mainly occurred. One to 4 mL of bulking agents polyacrylate (vantris/promedon was injected at the level of the intersymphyseal area and opening on either sides of the urethra. Results: Mean urinary continence score, before, 3 and 6months after injection Were (2.65 ± 074,(1.95 ± 082,(1.75 ± 0.78, respectively.(p < 0.001.

In our institution, the repair has evolved from a staged repair to one-stage reconstruction. The one-stage reconstruction includes; bladder closure, Cantwell-Ransley neourethroplasty and abdominoplasty using groin flaps, without the need of pelvic ostheotomies. Repair of urinary continence (UC and vesicoureteral reflux (VUR is done after development of the infant. Objective To present our experience of our modified one-stage reconstruction of bladder exstrophy in male patients. Materials and Methods Medical records of male patients submitted to one-stage reconstruction of bladder exstrophy were analyzed retrospectively. Fifteen exstrophy bladder patients with mean age 4.2±7 years were treated at our institution between 1999-2013. Results 2 5 Conclusions One-stage reconstruction minimizes the number of surgical procedures required to achieve UC and potentiates bladder-neck function. The advantages of using groin flaps over current techniques for complete repair are the small risk for penile tissue loss and the avoidance of ostheotomies.

Material and Methods. We retrospectively analyzed our data on 17 patients, operated between September 2001 and January 2010, who presented severe urinary incontinence and urethral/bladder neck stricture after prostatic surgery and failure of at least four conservative endoscopic treatments. Six patients underwent a transperineal urethrovesical anastomosis and 11 patients a combined transperineal suprapubical (endoscopic urethrovesical anastomosis.

After six months 16 patients were completely incontinent and presented a patent, stable lumen, so that they underwent an AUS implantation. With a mean followup of 50.5 months, 14 patients are perfectly continent with no postvoid residual urine. Conclusions. Two-stage procedures are safe techniques to treat these challenging cases. In our opinion, these cases could be managed with a transperineal approach in patients who present a perfect operative field; on the contrary, in more difficult cases, it would be preferable to use the other technique, with a combined transperineal suprapubical access, to perform a pull-through procedure.

    Objective:To re-examine the detailed anatomy of the muscular system at the bladder neck and proximal urethra in the male and to explore its function in urinary continence and micturition further. Methods:The pelvic organs, including bladder, prostate, and rectum, were obtained from 20 formalin-fixed adult male ca-davers and were removed from the pelvic cavity and embedded in celloidin in their entirety. The embedded block was cut into successive slices with an immersing-alcohol microtome. Results:Circular muscle fibers of the detrusor at the bladder outlet consist of the anterior downward projected circular muscle fibers of the bladder outlet ( AD-PC) , the bilateral accumulated circular fibers, and the posterior circular fibers of the bladder outlet. Together, these fibers concentrically surround the internal urethral orifice and trigone muscle. The lower part of the ADPC surrounds the ventral surface of the proximal urethra. Longitudinal muscle fibers are radially inserted into the circu-lar muscle around the internal urethral orifice. Numerous fibers from the ventral longitudinal muscle are inserted in-to the lower part of the ADPC. The upper part of the trigone muscle exists in bladder cavity;the lower part extends into the proximal urethra to surround the posterior and posterolateral surface of the urethra. Conclusions:The AD-PC and the upward extension of the rhabdosphincter comprise the anterior fibromuscular stroma. The circular mus-cle of the bladder outlet may be responsible for closure; the longitudinal muscle of the bladder outlet may be re-sponsible for opening of the internal urethral orifice and proximal urethra.

    2008-02-01

    The radical soft-tissue mobilization procedure was developed as a component of the staged closure of classical bladder exstrophy to improve continency rates without having to perform pelvic osteotomies. The authors describe complications following this procedure and discuss possible etiologies and subsequent management. We extracted from an institutionally approved exstrophy database the records of patients evaluated for complications following radical soft-tissue mobilization repair from 1999 to 2002. Four patients were referred to our institution following closure of exstrophy with the radical soft-tissue mobilization technique; two boys and two girls. Complications included ischemic penile injuries in both males, failed exstrophy closure in one female, incontinence with need for bladder neck transection and diversion in two patients, and upper tract deterioration in two patients of whom one required cystectomy and incontinent diversion. Omission of osteotomies when employing the radical soft-tissue mobilization repair appears to result in complications that could otherwise be prevented. Additionally, the complex dissection of the pelvic musculature, innervation and vasculature performed during radical mobilization has great potential to injure the pelvic structures and genitalia, as has been seen with the cases presented herein.

    Full Text Available Congenital anomalies such as meningomyelocele and diseases/damage of the central, peripheral, or autonomic nervous systems may produce neurogenic bladder dysfunction, which untreated can result in progressive renal damage, adverse physical effects including decubiti and urinary tract infections, and psychological and social sequelae related to urinary incontinence. A comprehensive bladder-retraining program that incorporates appropriate education, training, medication, and surgical interventions can mitigate the adverse consequences of neurogenic bladder dysfunction and improve both quantity and quality of life. The goals of bladder retraining for neurogenic bladder dysfunction are prevention of urinary incontinence, urinary tract infections, detrusor overdistension, and progressive upper urinary tract damage due to chronic, excessive detrusor pressures. Understanding the physiology and pathophysiology of micturition is essential to select appropriate pharmacologic and surgical interventions to achieve these goals. Future perspectives on potential pharmacological, surgical, and regenerative medicine options for treating neurogenic bladder dysfunction are also presented.

    Bladder exstrophy is a rare malformation characterized by an infra-umbilical abdominal wall defect, incomplete closure of the bladder with mucosa continuous with the abdominal wall, epispadias, and alterations in the pelvic bones and muscles. It is part of the exstrophy-epispadias complex, with cloacal exstrophy on the severe and epispadias on the mild ends of the spectrum. Bladder exstrophy is the most common of these entities and is more common in boys. The goal of this paper is to describe common methods of repair and to provide an imaging review of the postoperative appearances. (orig.)

    2008-01-01

    Full Text Available Genitourinary tuberculosis (GUTB occurs in 15-20% cases of pulmonary tuberculosis with a prevalence of 400 per 100,000 population. Reconstructive surgery for GUTB is required for cases with grossly distorted and dysfunctional anatomy that are unlikely to regress with chemotherapy alone. In the recent past, there has been a tremendous increase in the variety of reconstructive procedures for the urinary bladder, used in the management of GUTB. Augmentation cystoplasty includes the goals of increasing bladder capacity, while retaining as much of bladder as possible. Various bowel segments (from the stomach to the sigmoid colon have been used for bladder reconstruction. The choice of material for reconstruction is purely the surgeon′s prerogative--his skill, the ease, the mobility and length of mesentery (allowing bowel to reach the bladder neck without tension and maintaining an adequate blood supply. The presence or absence of concomitant reflux is of considerable importance. In the former, an ileocystoplasty with implantation of ureter to the proximal end of the isolated ileal loop and anastomosis of the distal end of the ileal loop to the bladder neck and trigone is advocated. In the latter case, the ureterovesical valve is preserved and colocystoplasty is preferred, wherein the sigmoid colon on being opened along its antimesentric border is joined to the trigone and bladder neck and then to itself to form a capacious pouch. Gastrocystoplasty reduces the risk of acidosis but is associated with complications like hypochloremic alkalosis and ′hematuria-dysuria′ syndrome. Orthotopic neobladder reconstruction is a feasible option, suitable in cases of tubercular thimble bladder with a markedly reduced capacity (as little as 15 ml, where an augmentation alone may be associated with anastomatic narrowing or poor relief of symptoms. In this article, we review the various bladder reconstruction options used for the surgical management of GUTB

    2011-02-01

    Full Text Available Abstract Introduction Hydronephrosis, reflux and renal failure are serious complications that occur in patients with neurogenic bladder associated with myelomeningocele. When the bladder compliance is lost, it is imperative to carry out surgery aimed at reducing bladder storage pressure. An ileocystoplasty, and for patients not suitable for intermittent catheterization, using the Mitrofanoff principle to form a continent stoma and the subsequent closure of the bladder neck, can be used. We report here, for the first time to the best of our knowledge, an association between two previously described techniques (the Mitrofanoff principle and the technique of Monti, that can solve the problem of a short appendix in obese patients. Case presentation A 33-year-old male Caucasian patient with myelomeningocele and neurogenic bladder developed low bladder compliance (4.0 mL/cm H2O while still maintaining normal renal function. A bladder augmentation (ileocystoplasty with continent derivation principle (Mitrofanoff was performed. During surgery, we found that the patient's appendix was too short and was insufficient to reach the skin. We decided to make an association between the Mitrofanoff conduit and the ileal technique of Monti, through which we performed an anastomosis of the distal stump of the appendix to the bladder (with an antireflux valve. Later, the proximal stump of the appendix was anastomosed to an ileal segment of 2.0 cm that was open longitudinally and reconfigured transversally (Monti technique, modeled by a 12-Fr urethral catheter, and finally, the distal stump was sutured at the patient's navel. After the procedure, a suprapubic cystostomy (22 Fr and a Foley catheter (10 Fr through the continent conduit were left in place. The patient had recovered well and was discharged on the tenth day after surgery. He remained with the Foley catheter (through the conduit for 21 days and cystostomy for 30 days. Six months after surgery he was

    Overactive bladder (OAB) is a condition affecting millions of individuals in the United States. Anticholinergics are the mainstay of treatment. Bladder botulinum toxin injections have shown an improvement in symptoms of OAB equivalent to anticholinergic therapy. Percutaneous tibial nerve stimulation can decrease symptoms of urinary frequency and urge incontinence. Sacral neuromodulation for refractory patients has been approved by the Food and Drug Administration for treatment of OAB, urge incontinence, and urinary retention. Few randomized, head-to-head comparisons of the different available alternatives exist; however, patients now have increasing options to manage their symptoms and improve their quality of life.

    Introduction: A long term, retrospective study was performed aiming to outline a critical comparison concerning the efficacy, safety and durability of the bipolar plasma vaporization (BPV), standard monopolar transurethral resection (TUR) and “cold-knife" “star" transurethral incision (TUI) in secondary bladder neck sclerosis (BNS) cases. Materials & Methods: Of the 126 patients included in the trial based on maximum flow rate (Qmax) below 10 mL/s and International Prostate Symptom Score (IPSS) over 19, classical resection was performed in 46 cases, “cold-knife" TUI in 37 cases and bipolar vaporization in 43 patients. The evaluation protocol comprised IPSS, QoL (quality of life) score, Qmax and PVR (post-voiding residual urinary volume) assessment performed at 1, 3, 6, 12, 18 and 24 months after the initial intervention. Results: Significant intraoperative complications (capsular perforation – 8.7%; bleeding – 4.3%) occurred secondary to monopolar resection. “Star" TUI was the fastest technique, followed by plasma-button vaporization (7.2 and 11.4 versus 16.5 minutes). BPV and TUI patients benefitted from the shortest catheterization periods (0.75 and 1 versus 2.0 days) and hospital stays (1.0 and 1.25 versus 2.0 days). Immediate postoperative adverse events consisted of hematuria (6.5% of the TUR cases) and acute urinary retention (8.1% of the TUI group). Significantly higher long term BNS recurrence rates requiring re-treatment were established in the TUI (18.7%) and TUR (12.8%) series by comparison to BPV (5.4%). Among patients that completed the follow-up protocol, equivalent IPSS, QoL, Qmax and PVR features were determined in the 3 study arms. Conclusions: The plasma vaporization approach was confirmed as a successful match to conventional TUR and “cold-knife" TUI in terms of surgical safety profile, postoperative recovery, therapeutic durability and urodynamic and symptom score parameters.

A avaliação do assoalho pélvico pela palpação digital e pelos cones vaginais mostrou que a função muscular é menos eficiente nas mulheres incontinentes.Purpose: to study the relationship between pelvic floor function and bladder neck mobility in women with and without stress urinary incontinence (SUI, in menacme and postmenopausal. Methods: sixty-one SUI patients were evaluated; 31 of them were in menacme and of these 17 had SUI and 14 did not have any complaint; 30 were postmenopausal and of these, 15 with SUI and 15 without SUI. Simple cystometry and empty supine stress test were performed in those who had urinary incontinence complaint. Bladder neck mobility was studied by ultrasound and by the Q-tip test. To study pelvic floor function, vaginal cones and digital palpation were used. Results: the bladder neck position in the incontinent women (Groups A and C, determined by ultrasound or the Q tip-test, was --11.8 cm in Group A and --12.5 cm in Group C, lower than the continent women, in whom the bladder neck was at +4.4 cm in Group B and +2.3 cm in Group D. There were no differences in bladder neck mobility among the continent menacme (9.1 cm and postmenopausal (9.5 cm groups. Also there were no differences among the incontinent groups (17.1 cm for Group A and 16.6 cm for Group C. The bladder neck mobility was greater in the incontinent women (A and C. Continent women had better results on evaluation of pelvic floor muscles than the incontinent ones, even using vaginal cones or digital palpation, and these results were not dependent on the hormonal status. Conclusion: a positive correlation was found between the Q-tip tests and ultrasound, and between test with vaginal cones and digital palpation. No significant correlation was found between pelvic floor function and bladder neck mobility.

    Full Text Available Skeletal metastasis as a primary presentation of gall bladder carcinoma is rare. A 50-year-old lady presented with neck pain and weakness in her right upper limb of 3 months duration. Clinical and imaging work-up suggested locally advanced gall bladder carcinoma with metastasis to cervical vertebra and sternum. Only one case till date has been reported where the patient presented with neurological symptoms due to pathological fracture secondary to metastasis from an occult gall bladder carcinoma. Although rare, an occult gall bladder cancer may present with neurological symptoms due to pathological fracture of spine secondary to metastasis. We present a brief review of literature of patients who presented with skeletal metastases in clinically silent gall bladder malignancy. Palliative care issues in advanced gall bladder carcinoma have also been discussed.

    Full Text Available OBJECTIVE: Propose a new experimental model of bladder instability in rabbits after partial bladder obstruction. MATERIALS AND METHODS: Thirty North Folk male rabbits, weighting 1,700 to 2,820 g (mean: 2,162 g were studied. The animals were distributed in 2 experimental groups, formed by 15 rabbits each: Group 1 - clinical control. In this group there was no surgical intervention; Group 2 - bladder outlet obstruction. In this group, after anesthetizing the animal, urethral cannulation with Foley catheter 10F was performed and then an adjustable plastic bracelet was passed around the bladder neck. It was then adjusted in order to not constrict the urethra. The following parameters were studied in M1 - pre-operative period; M2 - 4 weeks post-operatively moments: 1- urine culture; 2- cystometric study; 3- serum creatinine and BUN. RESULTS: Bladder weight was 2.5 times larger in the group with obstruction than in the control group. Cystometric evaluation showed a significant increase in maximal vesical volume in the final moment at Group G2. However, there was no statistically significant difference among the groups studied. There was no statistically significant difference between maximal detrusor pressure and vesical compliance in the different moments or in the studied groups. There was an absence of uninhibited detrusor contractions in all the animals in group 1, and involuntary contractions were detected in 93% of group 2 animals. There was no significant variation in BUN and serum creatinine either among the groups or in the same group. CONCLUSIONS: We observed in the group with obstruction a bladder weight 2.5 higher than normal bladders. We detected involuntary contractions in 93% of the animals in group 2, establishing this experimental model as appropriate to secondary bladder instability and partial bladder outlet obstruction.

    Full Text Available The dysfunction of the catheter in peritoneal dialysis (PD is a frequent compli-cation. However, perforation of organs are rare, particularly that of the urinary bladder. This re-quires an early diagnosis and prompt treatment of patients. We report here the case of a 38-year-old woman having end-stage renal disease due to autosomal-dominant polycystic kidney disease treated by PD since November 2000. Three years later, she was treated for Staphylococcal peritonitis. Four months later, she presented with a severe urge to urinate at the time of the fluid exchanges. The biochemical analysis of the fluid from the bladder showed that it was dialysis fluid. Injection of contrast through the catheter demonstrated the presence of a fistula between the bladder and the peritoneal cavity. She underwent cystoscopic closure of the fistulous tract and the PD catheter was removed. Subsequently, the patient was treated by hemodialysis. One month later, a second catheter was implanted surgically after confirming the closure of the fistula. Ten days later, she presented with pain at the catheter site and along the tunnel, which was found to be swollen along its track. The injection of contrast produced swelling of the subcutaneous tunnel but without extravasation of the dye. PD was withdrawn and the patient was put back on hemodialysis. Bladder fistula is a rare complication in PD and diagnosis should be suspected when patient complains of an urge to pass urine during the exchanges, which can be confirmed by contrast study showing presence of dye in the bladder. PD may be possible after the closure of the fistula, but recurrence may occur.

    Full Text Available Leiomyoma of the urinary bladder is a very rare entity and represents < 0.5% of all bladder tumours, with only 250 cases reported worldwide to date. We report a case of leiomyoma of the bladder 55 -year-old female presented with chief complaints lower abdomen pain since 1 year associated with intermittency, burning, frequency and hesitancy in micturation. Bimanual examination of the patient revealed a mass on the right side near the bladder neck. USG suggested a well circumscribed polypoidal soft tissue lesion seen projecting in urinary bladder lumen and attached to the posterior wall and base of bladder with no internal vascularity. On cystoscopic examination, large smooth sessile growth arising from the right postero-lateral wall was noted with right ureteric orifice not visualized. Magnetic resonance imaging showed Large well defined rounded soft tisssue lesion close to anterior surface of the cervix and vagina which was Isointense to the skeletal muscles on T1 and T2 images with small focal irregular cystic areas of necrosis seen. It could be urinary bladder neoplasm or sub serosal cervical fibroid. Transurethral resection of tumor was performed. The pathologic diagnosis was leiomyoma of the bladder. We discuss the diagnosis and management of leiomyoma of the bladder and briefly review the literature.

    Central efferent and afferent neural pathways to and from the human urinary bladder are well-characterized, but the location and arborization of these nerves as they traverse the serosa, muscularis, and urothelial layers are not clearly defined. The purpose of this study was to create a three dimensional map of the innervation of the human bladder trigone from the extrinsic perivesical adventitial nerve trunks to the urothelium. A male and a female human bladder were harvested from fresh frozen cadavers and fixed in formalin. The bladder neck and trigone region were serially sectioned (5 μm) and every 20th slide was stained (S100), scanned and aligned to create 3D maps. Nerve penetration into the detrusor muscle occurs with the highest frequency at the bladder neck and interureteric ridge. Nerves traveling parallel to the bladder lumen do so in the adventitia, beyond the outer border of detrusor. In females, the depth of these nerve bands is uniform at 0.7-1.7 cm below the luminal surface, the outer limits of which include the anterior vaginal wall. In the male, depth is more variable owing to detrusor hypertrophy with the minimum depth of nerves approximately 0.5 cm near the interureteric ridge and over 1 cm near the bladder neck. Myelinated neural pathways traversing in the human bladder in the region of the trigone have a discreet regional density. This 3D map of trigonal innervation may provide guidance to more precisely direct therapies for urinary incontinence or pelvic pain. Neurourol.

    Objective To close the incision of transvesical natural orifice transluminal endoscopic surgery (NOTES) with reserved sutures in pigs, and to assess the feasibility and safety of the technique, so as to lay a foundation for future clinical application. Methods Five female pigs were inserted with self-made Trocar into the bladder under general anesthesia. Guided by ureteroscope, the needle passed the top wall of the anterior bladder and reached the abdominal wall, with two suture ends reserved for closure, one at the abdominal wall and the other in the urethra(out of Trocar). After finishing the transvesical NOTES, we pulled the suture end at the abdominal wall to the bladder and knotted outside the Trocar; then we dragged the urethra suture end to make the knot on the abdominal wall locating on the lateral wall of bladder, and then the urethral suture was knotted in Trocar and the knot was pushed to the bladder wall using a knot pushing device; finally the bladder incision was closed. The closure of the bladder incision was observed and tested with water filling method. Results The first two cases failed due to the overweight and large size of the pigs, or because the bladder incision was to close to the bladder neck, or due to the poor quality of the suture. The procedures were successful in the following 3 pigs, with the operation time periods being 45 min, 30 min, and 25 min, and with satisfactory closure. Conclusion Reserved suture for incision closure of transvesical NOTES procedure is safe and feasible; the technique is easy to perform and needs no special surgery devices; and it deserves further study.%目的 尝试预留线关闭猪经膀胱自然腔道内镜手术(natural orifice transluminal endoscopic surgery,NOTES)切口,探讨其可行性、安全性,总结操作经验,为后续临床应用奠定基础.方法 雌香猪5只,全麻下置入自制膀胱鞘至膀胱.在输尿管镜的引导下,穿刺针穿刺膀胱顶前壁到腹下壁,预留2根关闭

    Neuropathy and cystopathy are two common conditions in patients with chronic diabetes. Despite obvious bladder sensory and motor nerve dysfunction in diabetes, no studies have selectively explored whether sensory or motor innervation is affected in the bladder. In the present study, we tested the hypothesis that loss of bladder sensory and motor fibers is responsible for bladder sensory and motor dysfunction. Parasympathetic and sensory innervation of the bladder dome and neck were examined using immunohistochemistry (IHC) and stereology in adult female rats 12weeks after induction of diabetes by streptozotocin. Naïve and age matched rats were evaluated as controls. Diabetic rats had mean blood glucose level of >400mg/dl, and bladder weights and thicknesses that were more than doubled compared to naïve rats. In naïve rats, parasympathetic vesicular acetylcholine transporter (VAT) and sensory calcitonin gene-related peptide (CGRP) immunopositive nerve fibers were located in bladder smooth muscle and were more densely distributed in the neck compared to the dome. Within the urothelial region, CGRP nerve fibers were densely distributed while VAT nerve fibers were sparsely distributed in the bladder neck and both were virtually absent in the bladder dome. Streptozotocin induced diabetes did not change the total nerve fiber length of either VAT or CGRP stained fibers in either the neck or dome. These studies indicate that hyperglycemia, induced by streptozotocin treatment, does not result in a loss of parasympathetic VAT or CGRP sensory nerve fibers, per se, but the doubling of bladder weight and mass does indicate a decrease in innervation density.

    2015-12-01

    Patients with head and neck cancer are seeking improved surgical procedures to avoid severe defects that result from head and neck cancer resection. Free flap reconstruction provides vascularized tissue that has been transferred from a distant donor site on a patient's body to a recipient site, markedly improving wound closure and protecting structures of the head and neck. This article discusses free flap procedures for reconstruction after head and neck cancer resection, including the following procedure phases: airway protection and neck dissections, tumor resection, flap harvest, microvascular anastomosis of the flap, and reconstruction and closure. The article also explains specific risk factors for patients undergoing free flap procedures that have been identified in the literature and include procedure length, hypothermia, and pressure injuries. Each of these factors is discussed regarding its specific effect on this patient population, and the nursing interventions to reduce these risks are identified.

    Mouse bladder wall injection is a useful technique to orthotopically study bladder phenomena, including stem cell, smooth muscle, and cancer biology. Before starting injections, the surgical area must be cleaned with soap and water and antiseptic solution. Surgical equipment must be sterilized before use and between each animal. Each mouse is placed under inhaled isoflurane anesthesia (2-5% for induction, 1-3% for maintenance) and its bladder exposed by making a midline abdominal incision with scissors. If the bladder is full, it is partially decompressed by gentle squeezing between two fingers. The cell suspension of interest is intramurally injected into the wall of the bladder dome using a 29 or 30 gauge needle and 1 cc or smaller syringe. The wound is then closed using wound clips and the mouse allowed to recover on a warming pad. Bladder wall injection is a delicate microsurgical technique that can be mastered with practice.

    There is a demand for tissue engineering of the bladder needed by patients who experience a neurogenic bladder or idiopathic detrusor overactivity. To avoid complications from augmentation cystoplasty, the field of tissue engineering seeks optimal scaffolds for bladder reconstruction. Naturally derived biomaterials as well as synthetic and natural polymers have been explored as bladder substitutes. To improve regenerative properties, these biomaterials have been conjugated with functional molecules, combined with nanotechology, or seeded with exogenous cells. Although most studies reported complete and functional bladder regeneration in small-animal models, results from large-animal models and human clinical trials varied. For functional bladder regeneration, procedures for biomaterial fabrication, incorporation of biologically active agents, introduction of nanotechnology, and application of stem-cell technology need to be standardized. Advanced molecular and medical technologies such as next generation sequencing and magnetic resonance imaging can be introduced for mechanistic understanding and non-invasive monitoring of regeneration processes, respectively.

    Objective: To investigate the clinicopathologic features and diagnostic criteria of urachal carcinoma in the bladder.Methods: Seven cases of urachal carcinoma in the bladder were analyzed retrospectively. Results: All the tumors were found locating in the dome of bladder. Of them, 4 were mucinous adenocarcinoma, one was well differentiated papillary enteric adenocarcinoma, one was well differentiated squamous carcinoma, and one was neuroendocrine carcinoma. Cystomorphous urachal remnants were found in 4 cases. The main complaint was hematuria and all patients underwent partial excision of bladder and urachus. Conclusion: Mucinous adenocarcinoma is the main histo-pathological type, and cystomorphous urachal remnants are often accompanied with urachal carcinoma in the bladder. The key diagnostic criteria of urachal carcinoma in bladder are site and histopathology. And to examine the specimens carefully to find the urachal remnants is important.

    Full Text Available Gallbladder perforation is a rare complication of cholecystitis and cholelithiasis. The high morbidity and mortality rates associated with this condition are due to delays in diagnosis and treatment since signs and symptoms of perforation do not differ significantly from those of uncomplicated cholecystitis. We report a case of 17 year old boy who presented with perforation at the neck of gall bladder with extrusion of a stone. It was associated with bile infected with S. typhi.

    Objective To review studies on diabetic bladder dysfunction (DBD),a common and bothersome complication of diabetes mellitus.Data sources We performed a search of the English literature through PubMed.The key words used were "diabetes" and "bladder dysfunction" or "cystopathy".Our own data and perspective are included in the discussion.Study selection Studies containing data relevant to DBD were selected.Because of the limited length of this article,we also referenced reviews that contain comprehensive amalgamations of relevant literature.Results The classic symptoms of DBD are decreased bladder sensation,increased bladder capacity,and impaired bladder emptying with resultant elevated post-void residual urine.However,recent clinical and experimental evidence indicate a strong presence of storage problems such as urge incontinence in diabetes.Recent studies of DBD in animal models of type 1 diabetes have revealed temporal effects of diabetes,causing an early phase of compensatory bladder function and a later phase of decompensated bladder function.The pathophysiology of DBD is multifactorial,including disturbances of the detrusor,urothelium,autonomic nerves,and urethra.Polyuria and hyperglycemia play important but distinctive roles in induction of bladder dysfunction in type 1 diabetes.Polyuria causes significant bladder hypertrophy in the early stage of diabetes,whereas oxidative stress in the bladder caused by chronic hyperglycemia may play an important role in the late stage failure of bladder function.Conclusions DBD includes time-dependent and mixed manifestations.The pathological alterations include muscle,nerve,and urothelium.Polyuria and hyperglycemia independently contribute to the pathogenesis of DBD.Treatments for DBD are limited.Future clinical studies on DBD in type 1 and type 2 diabetes should be investigated separately.Animal studies of DBD in type 2 diabetes are needed,from the natural history to mechanisms.Further understanding of the molecular

    We examined whether the existence of spina bifida occulta or ultrasonographic bladder abnormalities was related to the outcome of treatment for primary nocturnal enuresis in children. Between April 1996 and September 2005, a total of 77 subjects (53 boys and 24 girls, aged 5-18 years; mean age, 9.9 years) with primary nocturnal enuresis were studied. Plain X-ray films of the spine and ultrasonographic bladder measurements (bladder wall thickness, bladder neck descent and bladder neck opening) were obtained and the correlations with the outcome of treatment using imipramine hydrochloride were assessed. On plain X-ray films of the spine, spina bifida occulta (lumbar vertebrae in three, lumbosacral vertebrae in 19 and sacral vertebrae in 31) was recognized in 53 children (69%). Ultrasonographic bladder abnormalities were recognized in 40 children (52%). Children with lumbar and lumbosacral spina bifida occulta showed a higher rate of concomitant ultrasonographic bladder abnormalities (P = 0.006) and had a poorer response to treatment (P = 0.041) compared with the children who had sacral spina bifida occulta. Children with ultrasonographic bladder abnormalities had a worse response to treatment (P = 0.005) compared to the children without bladder abnormalities. The presence of lumbar spina bifida occulta and ultrasonographic bladder abnormalities was related to the outcome of treatment for primary nocturnal enuresis in children, suggesting that spinal radiography and vesical ultrasonography may be useful predictive tests.

    The variants of bladder exstrophy with duplication of the bladder are extremely rare and associated with further malformations of the genitourinary system. Initially, the clinical appearance is that of a classic exstrophy. In this case a second, regularly configured bladder with a normal supravesical urinary tract was found covered by an omphalocele like a cutaneous bag. At the same time, there was a duplication of the vagina and a bicornuate uterus. The surgical treatment, aiming at anatomic reconstruction of the genitourinary system and closure of the symphysis, was successfully performed without any complication.

  14. Orthotopic bladder substitution in men revisited: identification of continence predictors.

    Koraitim, M M; Atta, M A; Foda, M K

    2006-11-01

    We determined the impact of the functional characteristics of the neobladder and urethral sphincter on continence results, and determined the most significant predictors of continence. A total of 88 male patients 29 to 70 years old underwent orthotopic bladder substitution with tubularized ileocecal segment (40) and detubularized sigmoid (25) or ileum (23). Uroflowmetry, cystometry and urethral pressure profilometry were performed at 13 to 36 months (mean 19) postoperatively. The correlation between urinary continence and 28 urodynamic variables was assessed. Parameters that correlated significantly with continence were entered into a multivariate analysis using a logistic regression model to determine the most significant predictors of continence. Maximum urethral closure pressure was the only parameter that showed a statistically significant correlation with diurnal continence. Nocturnal continence had not only a statistically significant positive correlation with maximum urethral closure pressure, but also statistically significant negative correlations with maximum contraction amplitude, and baseline pressure at mid and maximum capacity. Three of these 4 parameters, including maximum urethral closure pressure, maximum contraction amplitude and baseline pressure at mid capacity, proved to be significant predictors of continence on multivariate analysis. While daytime continence is determined by maximum urethral closure pressure, during the night it is the net result of 2 forces that have about equal influence but in opposite directions, that is maximum urethral closure pressure vs maximum contraction amplitude plus baseline pressure at mid capacity. Two equations were derived from the logistic regression model to predict the probability of continence after orthotopic bladder substitution, including Z1 (diurnal) = 0.605 + 0.0085 maximum urethral closure pressure and Z2 (nocturnal) = 0.841 + 0.01 [maximum urethral closure pressure - (maximum contraction amplitude

    Full Text Available Paraganglioma of the urinary bladder are tumors of chromaffin tissue originating from the sympathetic innervations of the urinary bladder wall and are extremely rare. Being functional, in most of the cases they are recognized by their characteristic presentation of hypertensive crisis and postmicturition syncope. A silent presentation of a bladder paraganglioma is very unusual but quite dangerous as they are easily misdiagnosed and adequate peri-operative attention is not provided. Here, we are presenting one such silent paraganglioma in adult women who presented with only a single episode of hematuria and severe hypertensive crisis occur during its trans-urethral resection.

    Full Text Available Karan Wadhwa, Raj Singh, Lemke Z SolomonDepartment of Urology, Queen Alexandra Hospital, Portsmouth, UKAbstract: A 69-year-old man presented with sudden onset of macroscopic hematuria. While an ultrasound of the bladder revealed a posterior bladder mass, subsequent flexible cystoscopy demonstrated only an area of irregular urothelium. Initial general anesthetic cytoscopy and biopsy revealed conventional G2/3 T1 TCC. Histology of a further formal resection of this irregular area revealed carcinoma-in-situ and population of atypical cells with enlarged nuclei, prominent nucleoli, and varying quantities of cytoplasm showing plasma cell features. The immunohistochemistry was consistent with a plasmacytoma. There must be a high index of suspicion when ultrasound demonstrates a mass not detected by flexible cystoscopy, and biopsies/resection are advised to exclude extramedullary plasmacytoma (EMP as the cause. EMP of the urinary bladder is a rare entity with only 21 cases reported in the literature. In this report we describe a further case of EMP of the bladder associated with synchronous transitional cell carcinoma (TCC of the urothelium. We also highlight the important histopathological findings and review the current literature to report the outcomes of existing approaches to management of this rare form of bladder cancer. We believe this to be the first case reported in which a patient presented concurrently with bladder EMP and urothelial TCC. EMPs are highly radiosensitive tumors and in the case of head/neck disease, survival at 10 years is in the order of 65% following radical radiotherapy. Given the paucity of reported cases of primary bladder EMP, the optimal treatment regime remains unclear. In keeping with other anatomical sites current treatment is based to the assumed benefit of radical radiotherapy and prognosis appears to be better in those with no evidence of systemic disease.Keywords: bladder cancer, extramedullary plasmacytoma

    Full Text Available Aim: To observe the incidence of full or partial eyelid closure at death. Materials and Methods: The presence of ptosis was recorded in 100 consecutive hospice patient deaths. Results: Majority (63% of the patients died with their eyes fully closed, however, 37% had bilateral ptosis at death, with incomplete eye closure. In this study, central nervous system tumor involvement and/or acute hepatic encephalopathy appeared to be pre-mortem risk factors of bilateral ptosis at death. Conclusion: Organicity and not psychogenicity is, therefore, the likely etiology of failure of full eyelid closure at death.

    Full Text Available Spontaneous bladder perforation is an uncommon event in childhood. It is usually associated with bladder augmentation. We are presenting a case of bladder rupture in an infant with neurogenic bladder without prior bladder surgery. Three days after lipomyelomeningocele excision the patient showed signs and symptoms of acute abdomen. The ultrasound exploration revealed significant amount of intraperitoneal free fluid and therefore a laparoscopic exploration was performed. A posterior bladder rupture was diagnosed and repaired laparoscopically. Currently, being 3 years old, she keeps successfully dry with clean intermittent catheterization. Neurogenic bladder voiding function can change at any time of its evolution and lead to complications. Early diagnosis of spontaneous bladder rupture is of paramount importance, so it is essential to think about it in the differential diagnosis of acute abdomen.

    Patient: Male, 74 Final Diagnosis: Giant intradiverticular bladder tumor with metastasis Symptoms: Hematuria Medication:— Clinical Procedure: — Specialty: Urology Objective: Rare disease Background: Intradiverticular bladder tumors are rare. This renders diagnosis of an intradiverticular bladder tumor difficult. Imaging plays a vital role in achieving the diagnosis, and subsequently staging of the disease. Case Report: A 74-year-old male presented to our center with a few months history of constitutional symptoms. Upon further history, he reported hematuria two months prior to presentation, which stopped temporarily, only to recur a few days prior to coming to the hospital. The patient admitted to having lower urinary tract symptoms. However, there was no dysuria, no sandy urine, and no fever. Palpation of his abdomen revealed a vague mass at the suprapubic region, which was non tender. In view of his history and the clinical examination findings, an ultrasound of the abdomen and computed tomography (CT) was arranged. These investigations revealed a giant tumor that seemed to be arising from a bladder diverticulum, with a mass effect and hydronephrosis. He later underwent operative intervention. Conclusions: Intradiverticular bladder tumors may present a challenge to the treating physician in an atypical presentation; thus requiring a high index of suspicion and knowledge of tumor pathophysiology. As illustrated in our case, CT with its wide availability and multiplanar imaging capabilities offers a useful means for diagnosis, disease staging, operative planning, and follow-up. PMID:28246375

    We reported a case of a GCT of the urinary bladder and review the literature. A 23-year-old female presented with dysuria that had lasted for the previous 6 months. MRI revealed a 3 × 2.5 cm global mass in the anterior wall of urinary bladder. Cystoscopy showed a semispherical tumor approximately 3 cm in diameter that was covered with normal bladder mucosa and extended from the bladder neck to the anterior wall of the bladder. The patient underwent transurethral resection of the tumor. Histological examination and immunohistochemical staining showed a granular cell tumor (GCT). There were no features suggesting a malignant phenotype. On 6 months follow-up, the patient has remained free of bladder recurrence. We recommend careful pathologic assessment for establishing the appropriate diagnosis and either a conservative or aggressivesurgical treatment for benign or localized malignant GCT of the urinary bladder, respectively.

    Full Text Available Abstract Background Reconstruction of the head and neck after adequate resection of primary tumor and neck dissection is a challenge. It should be performed at one sitting in advanced tumors. Defects caused by the resection should be closed with flaps which match in color, texture and hair bearing characteristics with the face. Cervicopectoral flap is a one such flap from chest and neck skin mainly used to cover the cheek defects. Methods This study included twelve patients presenting with cancer of the head and neck to Izmir Ataturk Training Hospital and Adnan Menderes University Hospital. Tumor resection and neck dissection was performed in one session by the same surgeon. A single incision was made and a medially based cervicopectoral fascio-cutaneous flap was used for surgical exposure in neck dissection and for closure of defects after tumor resection. Results There was no major complication. Two flaps had partial superficial epidermolysis at the suture line. Good aesthetic and functional results were achieved. Conclusion The cervicopectoral flap is an excellent alternative for the reconstruction of head and neck. Harvesting and application of the flap is rapid and safe. Only a single incision is sufficient for dissection and flap elevation. This flap achieves perfect surgical exposure, makes neck dissection easy and allows one to perform both tumor resection and neck dissection in one session.

    A 63-year old male was referred to our emergency unit due to acute renal failure. The level of serum renal function tests levels, blood urea nitrogen (BUN)/creatinine, were 63 mmol/L/848 μmol/L. CT (Computarised Tomography) scan showed a huge bladder stone (5 cm x 6 cm x 5 cm) with increased bladder wall thickness. Post-renal acute renal failure due to bilateral ureterohydronephrosis was diagnosed. The huge bladder stone was considered to be the cause of ureterohydronephrosis and renal failure. The patient was catheterised and received haemodialysis immediately. He received haemodialysis four times during ten days of hospitalization and the level of serum renal function tests levels (BUN/ creatinine) decreased 18 mmol/L/123 μmol/L. After improvement of renal function, we performed cystoscopy that demonstrated normal prostatic urethra and bladder neck and bilaterally normal ureteral orifices. Bladder wall was roughly trabeculated and Bladder outlet was completely obstructed by a huge bladder stone. After cystoscopy open, cystolithotomy was performed to remove calcium phosphate and magnesium ammonium phosphate stone weighing 200 g removed. Four days after operation the patient was discharged uneventfully and urethral catheter was removed on the seventh day. Post-renal acute renal failure due to large bladder stones is rare in literature. According to the our knowledge; early diagnosis of the stone avoid growth to large size and prevent renal failure.

    Therapies for grief and loss have traditionally focused on the work of grieving. The goal was to reach an endpoint, now popularly called closure. There are, however, many people who, through no fault of their own, find a loss so unclear that there can be no end to grief. They have not failed in the work of grieving, but rather have suffered ambiguous loss, a type of loss that is inherently open ended. Instead of closure, the therapeutic goal is to help people find meaning despite the lack of definitive information and finality. Hope lies in increasing a family's tolerance for ambiguity, but first, professionals must increase their own comfort with unanswered questions. In this article, the authors, one a poet, the other a family therapist and theorist, offer a unique blending of theory, reflection, and poetry to experientially deepen the process of self-reflection about a kind of loss that defies closure. © FPI, Inc.

  10. Achieving closure at Fernald

    Bradburne, John; Patton, Tisha C.

    2001-02-25

    When Fluor Fernald took over the management of the Fernald Environmental Management Project in 1992, the estimated closure date of the site was more than 25 years into the future. Fluor Fernald, in conjunction with DOE-Fernald, introduced the Accelerated Cleanup Plan, which was designed to substantially shorten that schedule and save taxpayers more than $3 billion. The management of Fluor Fernald believes there are three fundamental concerns that must be addressed by any contractor hoping to achieve closure of a site within the DOE complex. They are relationship management, resource management and contract management. Relationship management refers to the interaction between the site and local residents, regulators, union leadership, the workforce at large, the media, and any other interested stakeholder groups. Resource management is of course related to the effective administration of the site knowledge base and the skills of the workforce, the attraction and retention of qualified a nd competent technical personnel, and the best recognition and use of appropriate new technologies. Perhaps most importantly, resource management must also include a plan for survival in a flat-funding environment. Lastly, creative and disciplined contract management will be essential to effecting the closure of any DOE site. Fluor Fernald, together with DOE-Fernald, is breaking new ground in the closure arena, and ''business as usual'' has become a thing of the past. How Fluor Fernald has managed its work at the site over the last eight years, and how it will manage the new site closure contract in the future, will be an integral part of achieving successful closure at Fernald.

  11. Tank closure reducing grout

    Energy Technology Data Exchange (ETDEWEB)

    Caldwell, T.B.

    1997-04-18

    A reducing grout has been developed for closing high level waste tanks at the Savannah River Site in Aiken, South Carolina. The grout has a low redox potential, which minimizes the mobility of Sr{sup 90}, the radionuclide with the highest dose potential after closure. The grout also has a high pH which reduces the solubility of the plutonium isotopes. The grout has a high compressive strength and low permeability, which enhances its ability to limit the migration of contaminants after closure. The grout was designed and tested by Construction Technology Laboratories, Inc. Placement methods were developed by the Savannah River Site personnel.

    Full Text Available Central venous catheterization through internal jugular vein is done routinely in intensive care units. It is generally safe, more so when the procedure is performed under ultrasound guidance. However, there could be inadvertent puncture of other vessels in the neck when the procedure is not performed under real-time sonographic guidance. Closure of this vessel opening can pose a challenge if it is an artery, in a location difficult to compress, and is further complicated by deranged coagulation profile. Here, we discuss the removal of an inadvertently placed catheter from subclavian artery with closure of arteriotomy percutaneously using arterial suture-mediated closure device.

    Urinary bladder injury is a rare complication during cesarean delivery. Little is known on maternal outcome following this injury. To evaluate short and long-term maternal outcome following bladder injury during cesarean delivery. A retrospective case series of all pregnancies complicated by full-thickness bladder injury during cesarean delivery in a single university affiliated tertiary medical center (August 2007-June 2016). Data on demographics, labor and surgery parameters, postpartum sequelae, and cystography were collected and reviewed by study personnel. Short-term maternal outcome included catheterization period, cystography results (if performed), any febrile illness and/or need for second operation prior to maternal discharge. Long term maternal outcome was obtained by searching our urology departmental and ambulatory database for follow up for all women. Univariate analysis was used to compare maternal outcome following first or repeat cesarean delivery. Of 17,326 cesarean deliveries performed during study period, 81 (0.47%) were complicated by bladder injury. Of them, 8 cases (9.9%) occurred during primary cesarean delivery (overall risk in primary cesarean 0.07%). Of the other 73 cases that followed repeated cesarean, adhesions were documented in 55 (75.3%) of them. Six cases (8.2%) had placenta accreta. Bladder injury occurred at peritoneal entry in 55 (67.9%) cases, and involved the bladder dome in 49 (60.5%) of them. Injury was diagnosed during cesarean delivery in all but 3 women, in whom abdominal pain and bloating prompted evaluation on first to third postoperative day. All 3 underwent re-laparotomy with bladder closure without further adverse sequelae. Cystography was performed in 35 patients on median postoperative day 8 (6-11 days). Eleven patients had abnormal findings as follows: 5 urinary leakage, 4 bladder wall irregularity and two urinary reflux. Two of the 11 patients (18%) required additional interventions: One patient required

    Basaloid squamous cell carcinoma is a biologically aggressive neoplasm mainly found in the head and neck region. Recently, four cases of basaloid squamous cell carcinoma of the bladder have been reported, and three of them occurred in patients with neurogenic bladder, repeated catheterizations and human papillomavirus infection of the urinary tract. To the best of our knowledge, none of the patients affected by basaloid squamous cell carcinoma of the bladder described in the literature had documented genital involvement by human papillomavirus. Herein, we describe the case of a woman with neurogenic bladder affected by basaloid squamous cell carcinoma of the bladder and by a concomitant genital tract human papillomavirus infection. © 2014 The Japanese Urological Association.

    Bladder cancer is understudied despite its high prevalence and its remarkable response to immunotherapy. Indeed, funding for studies to explore mechanisms of tumor immunity and novel new therapeutics is disproportionately lower for bladder cancer in comparison with malignancies of the breast, prostate, or lung. However, the recent successes of checkpoint blockade therapy suggest that new therapeutic strategies are on the horizon for bladder cancer. Here, we give a perspective into the evolution of bladder cancer therapy, focusing on strategies to treat high-risk nonmuscle invasive disease, followed by a discussion of recent advances in the treatment of muscle invasive bladder cancer and their potential applicability to lower stage disease. Finally, we explore immunotherapeutic strategies, which have been demonstrated to be successful in the treatment of other malignancies, for their potential to treat and cure patients with nonmuscle and muscle invasive bladder cancer.

    Full Text Available Este artigo examina a objeção ao fechamento [dedutivo] que surge no contexto de certos paradoxos epistêmicos, paradoxos cuja conclusão é que a crença justificada pode ser inconsistente. É universalmente aceito que, se essa conclusão é correta, o fechamento deve ser rejeitado, para que se evite a crença justificada em enunciados contraditórios (P, ~P. Mas, mesmo que os argumentos desses paradoxos - o paradoxo da falibilidade (do prefácio e o paradoxo da loteria - seja mal sucedidos, eles, ainda assim, sugerem a existência de evidência independente para uma objeção mais direta contra o fechamento. O exame do argumento da falibilidade revela uma exigência de modéstia epistêmica que viola o fechamento a partir de múltiplas premissas. A reflexão sobre o paradoxo da loteria nos confronta com um dilema em que cada alternativa fornece um contra-exemplo ao fechamento a partir de uma única premissa. Seja ou não possível a inconsistência racional, há uma objeção contra o fechamento. This paper examines the case against closure that arises in the context of certain epistemic paradoxes, paradoxes whose conclusion is that it is possible for justified belief to be inconsistent. It is generally agreed that if this conclusion is correct, closure must be rejected in order to avoid justified belief in contradictory statements (P, ~P. But even if the arguments of these paradoxes – the fallibility (preface paradox and the lottery paradox – are unsuccessful, they nonetheless suggest independent grounds for a more direct case against closure. Examination of the fallibility argument reveals a requirement of epistemic modesty that violates multiple premise closure. Reflection on the lottery paradox presents us with a dilemma in which each alternative provides a counterexample to single premise closure. Whether or not rational inconsistency is possible, there is a case against closure.

    The RELAP-7 code is the next generation nuclear reactor system safety analysis code being developed at the Idaho National Laboratory (INL). The code is based on the INL’s modern scientific software development framework, MOOSE (Multi-Physics Object Oriented Simulation Environment). The overall design goal of RELAP-7 is to take advantage of the previous thirty years of advancements in computer architecture, software design, numerical integration methods, and physical models. The end result will be a reactor systems analysis capability that retains and improves upon RELAP5’s and TRACE’s capabilities and extends their analysis capabilities for all reactor system simulation scenarios. The RELAP-7 code utilizes the well-posed 7-equation two-phase flow model for compressible two-phase flow. Closure models used in the TRACE code has been reviewed and selected to reflect the progress made during the past decades and provide a basis for the colure correlations implemented in the RELAP-7 code. This document provides a summary on the closure correlations that are currently implemented in the RELAP-7 code. The closure correlations include sub-grid models that describe interactions between the fluids and the flow channel, and interactions between the two phases.

  9. Evidence for Bladder Urothelial Pathophysiology in Functional Bladder Disorders

    Directory of Open Access Journals (Sweden)

    Susan K. Keay

    2014-01-01

    Full Text Available Understanding of the role of urothelium in regulating bladder function is continuing to evolve. While the urothelium is thought to function primarily as a barrier for preventing injurious substances and microorganisms from gaining access to bladder stroma and upper urinary tract, studies indicate it may also function in cell signaling events relating to voiding function. This review highlights urothelial abnormalities in bladder pain syndrome/interstitial cystitis (BPS/IC, feline interstitial cystitis (FIC, and nonneurogenic idiopathic overactive bladder (OAB. These bladder conditions are typified by lower urinary tract symptoms including urinary frequency, urgency, urgency incontinence, nocturia, and bladder discomfort or pain. Urothelial tissues and cells from affected clinical subjects and asymptomatic controls have been compared for expression of proteins and mRNA. Animal models have also been used to probe urothelial responses to injuries of the urothelium, urethra, or central nervous system, and transgenic techniques are being used to test specific urothelial abnormalities on bladder function. BPS/IC, FIC, and OAB appear to share some common pathophysiology including increased purinergic, TRPV1, and muscarinic signaling, increased urothelial permeability, and aberrant urothelial differentiation. One challenge is to determine which of several abnormally regulated signaling pathways is most important for mediating bladder dysfunction in these syndromes, with a goal of treating these conditions by targeting specific pathophysiology.

    2016-01-01

    The purpose of this manuscript is to add some more information in the present scientific literature on these nearly forgotten triangles of surgical importance. The neck is an area that lends itself to anatomical geometry, such as triangles. Many triangles of the neck have been described, and some are well-known, yet, some have been nearly forgotten, i.e., Lesser's triangle, Farabeuf triangle, Pirogoff's triangle, and Beclard's triangle. From the anatomic and surgical point of view, the neck is an amazingly interesting place. It is like a connection where crucial functional units meet and pass. Added surgical landmarks are always helpful to the surgeon while dealing with the neck. Described triangles of neck in this article are always reliable and constant landmarks for head and neck surgeons.

    Simple cysts are rare in the urinary bladder and can pose a diagnostic dilemma to both the urologist and the histopathologist. No case study was found in the database of Elsevier Science Direct, Spring-Link, or PubMed. We present two cases of subserous cyst in the bladder and discuss the diagnosis and treatment of the condition. The cystic lesion at bladder dome was detected by radiologic examination and confirmed by cystoscopy. In case 1, transurethral resection was first performed which was followed by partial cystectomy; In case 2, the cyst was removed with the urachus using laparoscopic surgery. The patients recovered uneventfully and the histopathology showed cysts in subserous layer of urinary bladder. The bladder cyst should be distinguished from urachal tumor, and laparoscopic partial cystectomy is the preferred operative procedure.

    Bladder cancer treatment, namely systemic therapy, was dominated in the last three decades due to the absence of newer therapeutic options other than chemotherapy regimens. Chemotherapy, by itself, both in first and second-line seems to have achieved the modest plateau of its possibilities at the cost of non-negligible toxicity. Targeted therapies, which changed the therapy of many different tumors, seem rather ineffective in bladder cancer. More recently, a new generation of Immunotherapy based regimens represent the most promising avenue for the future systemic treatment of bladder cancer. Checkpoint inhibition, namely PD1/PD-L1 pathway inhibition, showed impressive results in many other tumor types and are expected to become a major player in the treatment of bladder cancer. Other immunotherapy strategies such as fusion proteins represent distant, although promising, options. A brief overview of the current status of bladder cancer immunotherapy is presented.

  18. Chemoprevention of bladder cancer.

    Kamat, Ashish M; Lamm, Donald L

    2002-02-01

    The data presented herein, although highly supportive for a protective role of various nutrients against bladder cancer, are far from definitive. Many authorities question the validity of current recommendations for nutritional chemoprevention against bladder cancer. The reason for the wide variations reported in epidemiologic studies lies in the nature of observational studies. Dietary studies are limited in their conclusions because the protection afforded by the consumption of a particular nutrient may be multifactorial, with different components of the food exerting potential chemopreventive effects. Furthermore, measuring levels of nutrients in the food intake of populations is confounded by factors that might affect these levels and also the incidence of cancer. For example, vitamin A can come from animal or vegetarian sources. Because animal fat has been identified as a potential carcinogen in man, depending on the source of the vitamin, varying levels of protection might be deduced. In addition, chemoprevention studies using dietary supplements are expected to have mild effects, and large studies would be required to confirm statistical significance. Even with agents such as intravesical chemotherapy, only half the studies achieve statistical significance [29]. Prospective randomized trials with a large sample size, longer follow-up, and an extended duration of treatment are needed to clarify the association between micronutrients and cancer protection. With these caveats in mind, several recommendations can be made. Simple measures, such as drinking more fluids (especially water), can have a profound impact on the incidence of bladder cancer. Vitamins are being extensively studied in chemopreventive trials for different cancers. There is strong evidence for a chemoprotective effect of vitamin A in bladder cancer. The authors recommend 32,000 IU/day of vitamin A initially, with lower doses (24,000 IU) for persons less than 50 kg. Because liver toxicity is a

  1. FINAL CLOSURE PLAN SURFACE IMPOUNDMENTS CLOSURE, SITE 300

    Energy Technology Data Exchange (ETDEWEB)

    Lane, J E; Scott, J E; Mathews, S E

    2004-09-29

    Lawrence Livermore National Laboratory of the University of California (LLNL) operates two Class II surface impoundments that store wastewater that is discharged from a number of buildings located on the Site 300 Facility (Site 300). The wastewater is the by-product of explosives processing. Reduction in the volume of water discharged from these buildings over the past several years has significantly reduced the wastewater storage needs. In addition, the impoundments were constructed in 1984, and the high-density polyethylene (HDPE) geomembrane liners are nearing the end of their service life. The purpose of this project is to clean close the surface impoundments and provide new wastewater storage using portable, above ground storage tanks at six locations. The tanks will be installed prior to closure of the impoundments and will include heaters for allowing evaporation during relatively cool weather. Golder Associates (Golder) has prepared this Final Closure Plan (Closure Plan) on behalf of LLNL to address construction associated with the clean closure of the impoundments. This Closure Plan complies with State Water Resources Control Board (SWRCB) Section 21400 of the California Code of Regulations Title 27 (27 CCR {section}21400). As required by these regulations and guidance, this Plan provides the following information: (1) A site characterization, including the site location, history, current operations, and geology and hydrogeology; (2) The regulatory requirements relevant to clean closure of the impoundments; (3) The closure procedures; and, (4) The procedures for validation and documentation of clean closure.

  2. Aesthetic, urological, orthopaedic and functional outcomes in complex bladder exstrophy-epispadias′s management

    2015-01-01

    Full Text Available Background: Postoperative complications are related to the surgical procedures, of failures of initial bladder closure and influence the urological, aesthetical and orthopaedic outcomes. Materials and Methods: We reviewed four patients who underwent complex bladder exstrophy-epispadias repair over a period of 14 years. The outcomes of treatment were assessed using, aesthetic, urological and orthopaedic examination data. Orthopaedic complications were explored by a radiography of the pelvis. Results: Out of four patients who underwent bladder exstrophy surgical management, aesthetic, functional outcomes and complications in the short and long follow-up were achieved in three patients. The first patient is a male and had a good penis aspect. He has a normal erection during micturition with a good jet miction. He has a moderate urinary incontinence, which requires diaper. In the erection, his penis-measures 4 cm long and 3 cm as circumference. The second patient was a female. She had an unsightly appearance of the female external genitalia with bipartite clitoris. Urinary continence could not be assessed; she did not have the age of cleanness yet. The third patient had a significant urinary leakage due to the failure of the epispadias repair. He has a limp, a pelvic obliquity, varus and internal rotation of the femoral head. He has an inequality of limbs length. Pelvis radiograph shows the right osteotomy through the ilium bone, the left osteotomy through the hip joint at the acetabular roof. Conclusion: When, the epispadias repair is performed contemporary to initial bladder closure, its success is decisive for urinary continence. In the female, surgical revision is required after the initial bladder closure for an aesthetic appearance to the external genitalia. Innominate osteotomy must be performed with brilliancy amplifier to avoid osteotomy through to the hip joint to prevent inequality in leg length.

    Full Text Available Herniation of the urinary bladder into the inguinal canal is an uncommon finding, observed in 0.5–4% of inguinal hernias (Curry (2000. It is usually associated with other conditions that increase intra-abdominal pressure such as bladder neck obstruction due to prostatic hypertrophy. Consequently, in men, it is usually associated with some degree of urinary retention. We present a 42-year-old man in whom herniation of the urinary bladder was the cause of urinary retention, and not vice versa. The patient was on tumor necrosis factor alpha antagonist (TNFA (Etanercept for severe Ankylosing spondylitis. Initially, the urinary retention was thought to be a side effect of the medication, but after the drug was discontinued, urinary retention persisted. CT and MRI demonstrated huge herniation of the urinary bladder into the inguinal canal. Immediately after the hernia was repaired, bladder function was restored. TNF treatment was restarted, and no further urinary symptoms were observed in the next two years of follow-up. In this case, the primary illness and its treatment were distracting barriers to early diagnosis and treatment. In younger patients with a large hernia who develop unexpected urinary retention, herniation of the urinary bladder should be highly considered in the differential diagnosis.

    Bladder diverticulum, an outpouching of the mucosa through the muscular wall of the bladder, is a multifactorial disease process that can be either acquired or congenital. Although small diverticuli are usually asymptomatic, a large diverticulum may result in hematuria, urinary tract infection, acute abdomen due to its rupture, acute urinary retention, or neoplasm formation. We describe the case of an elderly gentleman who presented to the emergency department with abdominal pain and was ultimately diagnosed with bladder diverticulitis, a disease not previously described in the literature.

    2015-11-01

    Overactive bladder is one of the most common bladder problems, but an estimated 20 million Americans have underactive bladder (UAB), which makes going to the bathroom difficult, increases the risk of urinary tract infections, and even leads to institutionalization. This article provides an overview of UAB in older adults, and discusses the prevalence, predisposing factors, cause, clinical investigations, and treatments. At present, there is no effective therapy for UAB. A great deal of work still needs to be done on understanding the pathogenesis and the development of effective therapies.

    Retrospective review of bladder carcinoma at this institution has revealed a high incidence of squamous cell carcinoma associated with bilharzia infection as has been found in other Mideast and African countries. Associated inflammatory and epithelial metaplastic changes were commonly noted and apparently represent early changes in the development of carcinoma, particularly in view of the progression from squamous metaplasia to in situ and infiltrating carcinoma observed in both bladder and ureter. The relationship between bilharzia infection and the development of bladder carcinoma has been postulated to be related to several factors; however, as yet the specific etiologic relationship and pathogenesis have not been defined.

  8. Planning for integrated mine closure

    Energy Technology Data Exchange (ETDEWEB)

    Linda Starke (ed.)

    2008-07-01

    This document presents an Integrated Mine Closure Planning Toolkit for the mining and metals sector. The toolkit is intended to be used to promote a more disciplined approach to integrated closure planning and to increase the uniformity of good practices across the sector. The concepts apply equally well to both large and small companies. The document is not intended to be prescriptive; it provides a suite of tools that can be brought to bear in formulating well-considered decisions when planning for closure. It uses a risk and opportunity based process to guide the practitioner through the iterative process of preparing for planned closure. The first section, with head office and mine management personnel as the primary audience, describes the participants of effective closure planning. Sections 2 and 3 provide the frameworks for a conceptual closure plan and a detailed plan. The key audiences for these two sections are mine management and head office personnel, financial modellers and estimators, governments, academics and non-governmental organizations. The forth section addresses decommissioning and post closure planning, and Section 5 draws together the conclusions and outlines several unresolved issues. The five narrative sections are followed by Section 6 which outlines 13 tools, some of which are already available in earlier ICMM publications, member practices and other sector-affiliated publications. Others have been developed to cover identified gaps. These tools provide the practitioner with practical work processes, examples and contexts within which to apply closure planning discipline.

    Carvalho, E T; Junqueira, L C

    1999-03-01

    The histology of the kidney and urinary bladder of Siphonops annulatus was studied by light microscopy in semithin sections of tissue embedded in hydrophilic resin. The kidney's nephron comprises the renal corpuscle, neck segment, proximal tubule, intermediate segment, distal tubule and collecting tubule. Nephrostomes are present. This structure, the neck segment, and intermediate tubules present long cilia, and probably play important roles in the propulsion of the peritoneal fluid and glomerular filtrate. The proximal tubule cells possess loosely packed microvilli and contain abundant polymorphic granules and vesicles that assume the aspect of lysosomes in different stages of intracellular digestion. The distal tubules are characterized by large, vertically disposed mitochondria assuming the aspect of ions transporting cells. The urinary bladder is lined with a transitional epithelium, whose aspect varies according to the quantity of urine.

    Full Text Available Hepatobiliary ascariasis is commonly reported from highly endemic regions like India, Bangladesh, Latin America, parts of Middle East and Africa. In humans, the usual habitat of Ascaris lumbricoides is the small intestine. When the worm load is high, going as high as more than 1000 worms, then the worms tend to migrate away from the usual site. Patients with hepatobiliary ascariasis may present with biliary colic due to obstruction caused by the worms in the gall bladder, common bile duct or as a result of obstructive symptoms caused by calcified worms or lithiasis, which is commonly found in patients with hepatobiliary ascariasis. Acute pancreatitis may also be caused by ascariasis. Management usually is conservative if it is still alive or can be extracted by endoscopic retrograde cholangio-pancreatography or surgery.

  15. Increased residual urine in patients with bladder neuropathy secondary to suprasacral spinal cord lesions.

    Science.gov (United States)

    Mayo, M E; Kiviat, M D

    1980-05-01

    Multichannel urodynamic studies were done on 30 patients with incomplete bladder emptying secondary to suprasacral spinal cord lesions. In 11 patients fluoroscopy was done simultaneously. A single most important factor accounting for the increased residual urine was present in 21 cases: inadequate detrusor contraction in 10, sphincter dyssynergia in 6 and bladder neck obstruction in 5. A combination of 2 of these factors was present in 3 patients. Although the initial residual urine volume was high in 6 patients voiding during the urodynamic study was efficient and no residual urine was demonstrated at that time. Urethral pressure profiles were variable, depending on whether a spastic external sphincter contraction was present during the procedure. It is concluded that bladder pressure and sphincter electromyographic measurement during voiding, combined with fluoroscopy, are ideal methods to identify the factors responsible for incomplete emptying in problem cases. The urethral pressure profile is of limited value in the initial assessment of these patients.

    1994-01-01

    We encountered a rare patient with Hunter's syndrome who exhibited urinary retention as a result of a neurogenic bladder, uninhibited detrusor contractions, and detrusor-sphincter dyssynergia. Neurological findings were consistent with cervical myelopathy and cervical MR imaging showed very narrow segments at the cord level C2-4. We speculate that this Hunter's syndrome patient has cervical myelopathy and that this neurological dysfunction causes the neurogenic bladder. PMID:8014981

    Full Text Available Background. The incidence of bladder cancer is rising in Slovenia and in most countries in the World. Increasing incidence is probably due to aging population and risk factors. Approximately 75–85% of patients present with disease confined to mucosa (Ta-Tis, or submucosa (T1 stage. The other 15–25% have muscle invasion or nodal disease (stages T2-T4, N+ at presentation.Conclusions. The diagnosis of bladder cancer ultimately depends on cystoscopic examination of the bladder and histopathological evaluation of resected lesion. After transuretral resection (TUR treatment of superficial bladder tumors (TaT1 will be directed towards the prevention of recurrence and progression with bladder instillation of vaccine for tuberculosis (bacillus Calmette-Guerin-BCG or chemotherapeutic agents. Tumors of T2 or higher category are infiltrating tumors and cystectomy is necessary in the majority of cases. Incontinent or continent urinary diversion is presently considered after radical cystectomy. Contra-indications for cystectomy are major co-morbidity and patients not willing to accept the surgery. Bladder preservation with chemo and radiotherapy can be an option in these selected cases.

    Full Text Available In this overview the influence of functional bladder disturbances and of its treatment on the resolution of vesicoureteral reflux (VUR in children is discussed. Historically both bladder dysfunction entities, the overactive bladder (OAB and the dysfunctional voiding (DV, have been described in conjunction with VUR. Treatment of the dysfunction was also considered to influence spontaneous resolution in a positive way. During the last decades, however, papers have been published which could not support these results. Regarding the OAB, a prospective study with treatment of the bladder overactivity with anticholinergics, did not influence spontaneous resolution rate in children with a dysfunction including also the voiding phase, DV and DES (dysfunctional elimination syndrome, most studies indicate a negative influence on the resolution rate of VUR in children, both before and after the age for bladder control, both with and without treatment. However, a couple of uncontrolled studies indicate that there is a high short-term resolution rate after treatment with flow biofeedback. It should be emphasized that the voiding phase dysfunctions (DV and DES are more severe than the genuine filling phase dysfunction (OAB, with an increased frequency of UTI and renal damage in the former groups. To be able to answer the question if treatment of bladder dysfunction influence the resolution rate of VUR in children, randomized controlled studies must be performed.

    Full Text Available Introduction. Femoral neck fractures in children and adolescents are rare. However, their complications are frequent - avascular necrosis, femoral neck pseudoarthrosis, premature physeal closure with consequent growth disturbance and coxa vara deformity. Case Outline. A 9.5­year­old boy was injured in a car accident, and femoral neck fracture was diagnosed. Prior to admission at our hospital he was surgically treated several times. He was admitted at our hospital eight months following the accident. On the X­ray transcervical pseudoarthrosis of the femoral neck was found, as well as coxa vara deformity and metaphyseal avascular necrosis. He was operated at our hospital; all previously placed ostefixation material was removed, valgus osteotomy of 30 degrees was done as well as additional local osteoplasty using the commercial osteoindactive agent (Osteovit®. Postoperatively, we applied skin traction, bed rest and physical therapy. At the final follow­up, the patient was recovered completely. He is now painless, the legs are of equal length, range of movements in the left hip is full, life activity is normal. The X­ray shows that the femoral neck pseudoarthrosis is fully healed. Conclusion. This case is presented in order to encourage other colleagues to challenge the problematic situation such as this one. Also, we would like to remind them what one should think about and what should be taken into consideration in the primary treatment of femoral neck fractures in children. Valgus femoral osteotomy, as a part of the primary treatment of femoral neck fracture in children (identically as in the adults can prevent the occurrence of femoral neck pseudoarthrosis.

    Radical cystectomy is the standard treatment for localised muscle invasive bladder cancer (MIBC). We offer a bladder-sparing treatment with TURB +/- Chemotherapy+Radiotherapy to selected patients as an alternative. We analyze, retrospectively, 30 patients diagnosed with MIBC from March 1991 to October 2010. The mean age was 62.7 years (51-74). All patients were candidates for a curative treatment, and underwent strict selection criteria: T2 stage, primary tumor, solitary lesion smaller than 5cm with a macroscopic disease-free status after TURB, negative random biopsy without hydronephrosis. Staging CT evaluation was normal. Restaging TURB or tumor bed biopsy showed a disease-free status or microscopic muscle invasion. 14 patients underwent TURB alone, 13 TURB+Chemotherapy and 3 TURB+Chemotherapy+Radiotherapy. The mean follow up was 88.7 months (19-220). 14 patients remained disease free (46.6%), 10 had recurrent non-muscle invasive bladder cancer (33%). 81.3% complete clinical response. 71% bladder preserved at 5-years. Overall, 5-years survival rate was 79% and 85% cancer-specific survival rate. Although radical cystectomy is the standard treatment for localised MIBC, in strictly selected cases, bladder-sparing treatment offers an alternative with good long term results.

  5. Overactive bladder in children

    Overactive bladder (OAB) is a highly prevalent disorder in the pediatric population. This condition is especially troublesome for pediatric patients and their families when associated with incontinence, since it negatively affects self-esteem and impairs children’s development. From the patient’s perspective, urgency and urge incontinence can have a significant impact, negatively affecting their quality of life. For a therapy to have true benefit, changes must not only be statistically significant, but must also be perceived as meaningful by the patient. A stepwise approach is favoured to treat this pathology, starting with behavioural therapy, followed by medical management, and eventually more invasive procedures. Antimuscarinic agents are the mainstay of medical treatment for OAB. Oxybutynin is the most commonly used antimuscarinic in the pediatric population. However, some patients have a suboptimal response to antimuscarinics and many experience bothersome side effects, which have been documented with all antimuscarinics to a significantly higher degree than placebo. Although there have been reports about the use of tolterodine, fesoterodine, trospium, propiverine, and solifenacin in children, to date, only oxybutynin has been officially approved for pediatric use by medical authorities in North America. This review will address alternative treatment options for pediatric patients presenting with OAB, from conservative measures to more invasive therapies. PMID:28265325

    2005-08-26

    The purpose of the ''Closure and Sealing Design Calculation'' is to illustrate closure and sealing methods for sealing shafts, ramps, and identify boreholes that require sealing in order to limit the potential of water infiltration. In addition, this calculation will provide a description of the magma that can reduce the consequences of an igneous event intersecting the repository. This calculation will also include a listing of the project requirements related to closure and sealing. The scope of this calculation is to: summarize applicable project requirements and codes relating to backfilling nonemplacement openings, removal of uncommitted materials from the subsurface, installation of drip shields, and erecting monuments; compile an inventory of boreholes that are found in the area of the subsurface repository; describe the magma bulkhead feature and location; and include figures for the proposed shaft and ramp seals. The objective of this calculation is to: categorize the boreholes for sealing by depth and proximity to the subsurface repository; develop drawing figures which show the location and geometry for the magma bulkhead; include the shaft seal figures and a proposed construction sequence; and include the ramp seal figure and a proposed construction sequence. The intent of this closure and sealing calculation is to support the License Application by providing a description of the closure and sealing methods for the Safety Analysis Report. The closure and sealing calculation will also provide input for Post Closure Activities by describing the location of the magma bulkhead. This calculation is limited to describing the final configuration of the sealing and backfill systems for the underground area. The methods and procedures used to place the backfill and remove uncommitted materials (such as concrete) from the repository and detailed design of the magma bulkhead will be the subject of separate analyses or calculations.

    Deep neck space abscesses are common otolaryngological emergencies, and prompt incision and drainage is the treatment of choice. Head and neck cancers often present with cervical metastases that may become secondarily infected. Clinical presentation is similar to a deep neck abscess. Surgical drainage of such collections has implications on subsequent treatment. In this case series, we describe six cases with this unusual presentation that were subsequently found to have a head and neck malignancy, and where three patients had their abscesses treated surgically. We aim to raise awareness of this unusual presentation of a head and neck carcinoma, and to avoid a potential pitfall in the management of deep neck abscess.

    Full Text Available Overactive bladder (OAB, as defined by the International Continence Society, is characterized by a symptom complex including urinary urgency with or without urge incontinence, usually associated with frequency and nocturia. OAB syndrome has an incidence reported from six European countries ranging between 12-17%, while in the United States; a study conducted by the National Overactive Bladder Evaluation program found the incidence at 17%. In Asia, the prevalence of OAB is reported at 53.1%. In about 75%, OAB symptoms are due to idiopathic detrusor activity; neurological disease, bladder outflow obstruction (BOO intrinsic bladder pathology and other chronic pelvic floor disorders are implicated in the others. OAB can be diagnosed easily and managed effectively with both non-pharmacological and pharmacological therapies. The first-line treatments are lifestyle interventions, bladder training, pelvic floor muscle exercises and anticholinergic drugs. Antimuscarinics are the drug class of choice for OAB symptoms; with proven efficacy, and adverse event profiles that differ somewhat.

    2007-01-01

    Full Text Available Structural urologic abnormalities resulting in dysfunctional lower urinary tract leading to end stage renal disease may constitute 15% patients in the adult population and up to 20-30% in the pediatric population. A patient with an abnormal bladder, who is approaching end stage renal disease, needs careful evaluation of the lower urinary tract to plan the most satisfactory technical approach to the transplant procedure. Past experience of different authors can give an insight into the management and outcome of these patients. This review revisits the current literature available on transplantation in abnormal bladder and summarizes the clinical approach towards handling this group of difficult transplant patients. We add on our experience as we discuss the various issues. The outcome of renal transplant in abnormal bladder is not adversely affected when done in a reconstructed bladder. Correct preoperative evaluation, certain technical modification during transplant and postoperative care is mandatory to avoid complications. Knowledge of the abnormal bladder should allow successful transplantation with good outcome.

  10. Molecular markers in bladder cancer.

    Hussain, Syed A; James, Nicholas D

    2005-01-01

    Bladder cancer is one of the malignancies for which extensive information regarding molecular pathogenesis and genetic predictors of natural history as well as response to various modalities of treatment based on molecular profile is available. As more prognostic markers are being investigated in clinical trial settings, in the not very distant future we will be able to use these predictive markers in clinical decision-making. Bladder cancer is the second most common genitourinary tumor and is a significant cause of morbidity and mortality. A need for tumor markers that can be incorporated into clinical practice to add prognostic information and to refine the conventional TNM and grading systems in terms of treatment response and prognosis is crucial. Intravesical and systemic chemotherapy in bladder cancer are limited in their efficacy in the treatment of bladder cancer patients primarily when they are unable to induce apoptosis in bladder tumor cells. Understanding the apoptotic signals and the cascade of reactions that give pro-survival signals will go a long way in refining the treatments and will help in the future to individualize cancer therapies. It is imperative to study the role of these mechanisms in prospective clinical trials in a quest to find predictive markers that can help to tailor treatments, keeping in view the molecular heterogeneity.

    Full Text Available Advances in head and neck reconstruction has made significant improvement in the quality of life and resectability of head and neck cancer. Refinements in microsurgical free tissue transfer leave made restoration of form and complex functions of head and region a reality. Standardized reconstructive algorithms for common head and neck defects have been developed with predictable results. Some of the major advances in the field include- sensate free tissue transfer, osseo integrated implant and dental rehabilitation, motorized tissue transfer and vascularized growth center transfer for pediatric mandible reconstruction. However there exist several controversies in head and neck reconstructive surgery. Some are old; resolved partially in the light of recent clinical evidences and others are new, developed as a result of newly introduced reconstructive techniques. These include, primary versus secondary reconstruction, pedicled versus free flaps, primary closure versus free tissue transfer for partial glossectomy defects, reconstruction of posterior mandible and reconstruction of orbital exenteration defects. Rapid advances in the field of tissue engineering and stem cell research is expected to make radical change in the field of reconstructive surgery. This manuscript review progress in head and neck reconstructive surgery during the last decade, current controversies and outline a road map for the future.

    2015-09-01

    The loss of urinary bladder control/sensation, also known as urinary incontinence (UI), is a common clinical problem in autistic children, diabetics, and the elderly. UI not only causes discomfort for patients but may also lead to kidney failure, infections, and even death. The increase of bladder urine volume/pressure above normal ranges without sensation of UI patients necessitates the need for bladder sensors. Currently, a catheter-based sensor is introduced directly through the urethra into the bladder to measure pressure variations. Unfortunately, this method is inaccurate because measurement is affected by disturbances in catheter lines as well as delays in response time owing to the inertia of urine inside the bladder. Moreover, this technique can cause infection during prolonged use; hence, it is only suitable for short-term measurement. Development of discrete wireless implantable sensors to measure bladder volume/pressure would allow for long-term monitoring within the bladder, while maintaining the patient's quality of life. With the recent advances in microfabrication, the size of implantable bladder sensors has been significantly reduced. However, microfabricated sensors face hostility from the bladder environment and require surgical intervention for implantation inside the bladder. Here, we explore the various types of implantable bladder sensors and current efforts to solve issues like hermeticity, biocompatibility, drift, telemetry, power, and compatibility issues with popular imaging tools such as computed tomography and magnetic resonance imaging. We also discuss some possible improvements/emerging trends in the design of an implantable bladder sensor.

    1991-01-01

    Occupational exposure to health hazards was studied in 258 industrial workers who had developed cancer of the bladder against 454 matched controls. All the test subjects and controls were residents of the Tambov Province centers of chemical industry. Statistical significance (relative risk-4.7) was established for exposure to aromatic amines. For those contacting with aniline dyes the relative risk (RR) made up 2.4. The risk to develop bladder cancer in powder shops (RR-3.2) was attributed to the hazards of dyes and diphenylamine. In leather-shoe and textile industry the exposure to dyes was not safe (RR-6.1), neither was it to chemicals, oil products, pesticides, overheating (RR-3.2, 1.6, 3.2 and 2.9, respectively). It is stated that in line with a significant risk to develop bladder cancer at exposure to aromatic amines there exist a number of occupational factors contributing to this risk.

The first one shows a giant bladder lithiasis resulting in severe renal insufficiency in a 63-year-old patient, who had previously had nicturia (2-3 times), occasional episodes of urinary frequency and burning micturition, in the absence of renal colic, hematuria or interrupted urination. The second case referes to an 85-year-old man suffering from prostatic enlargement and bladder stones, hospitalized to undergo intervention of trans-vesical prostatic adenomectomy, during which two star-shaped stones were found without obvious symptoms.

    Objective: To present a batch of data of transected pancreatic neck injuries and to sum up the experience in surgical interventions for the injuries.Methods: We analysed 13 patients with a transected injury to the pancreatic neck from Jan. 1995 to Dec. 2000. External drainage was performed in all patients. Pancreatoduodenectomy was conducted in 2 patients with a transected injury to the pancreatic neck associated with duodenal ruptures, and TPN was administered immediately after operation. Proximal closure of the transected margin and distal pancreaticojejunostomy was performed in 4 patients. Proximal closure of the transected margin and distal pancreaticojejunostomy plus splenectomy was performed in 7 patients associated with contusion of pancreatic body or tail plus spleen rupture. Results: 12 patients healed and one patient died of anesthetic accident during the course of restoration of the dislocation of his right hip joint. Complications occurred in 7 patients.Conclusions: The operation should be performed according to the degree of the injuries and associated duodenal injuries. Routine drainage and nutrient support should be recommended.

    Malakoplakia that presents in the head and neck is very rare. We describe a 76-year-old man who presented with an inflammatory mass in the lateral aspect of the neck that clinically mimicked a tumoral expansion and was consistent with a cervical malakoplakia. To our knowledge, this is the second case reported with manifestations of this chronic inflammatory disease localized in the neck. Malakoplakia is a rare granulomatous disease that most frequently involves the genitourinary tract and occurs in an immunodeficient host. The symptoms are nonspecific and the diagnosis is based on the histologic findings. In the present case, the biopsy specimen of the cervical mass revealed a collection of numerous von Hansemann cells containing Michaelis-Gutmann bodies, which are pathognomonic of malakoplakia. Bacteriologic analysis identified Escherichia coli. The evolution was favorable after surgical excision and prolonged antibiotic therapy with fluoroquinolones.

    Full Text Available Air within the bladder wall, or bladder pneumatosis, is a very rare finding typically resulting from an infectious etiology, as in emphysematous cystitis (EC. However, there have been reports of bladder pneumatosis occurring without clear infectious origins. We present a case of a female patient found to have concurrent bladder and ileal pneumatosis secondary to a catastrophic vascular event. Prompt recognition of non-infectious etiologies of bladder pneumatosis is essential as this distinction may dramatically alter clinical decision-making.

    While smoking and exposure to certain chemicals are well-defined risk factors for bladder cancer, there is no consensus as to the roles of modifiable lifestyle factors, notably physical activity, and obesity. We evaluated associations of obesity and physical activity with bladder cancer risk by performing a system-wide search of PubMed for cohort and case-control studies focused on obesity, exercise, and bladder cancer. A total of 31 studies were identified that evaluated the associations of obesity and physical activity with bladder cancer risk: 20 focused on obesity, eight on physical activity, and three on both. There was marked heterogeneity in population composition and outcomes assessment. Fifteen (65%) of the obesity studies used prevalence or incidence as the primary outcome and seven (30%) used bladder cancer mortality. Ten (44%) observed positive and 13 (56%) null associations of obesity with bladder cancer. Three (100%) of three studies also noted strong positive associations of obesity with bladder cancer progression or recurrence. Ten (91%) of the physical activity studies analyzed prevalence or incidence and one (9%) mortality. One (9%) study observed positive, seven (64%) null, and three (27%) negative associations of physical activity with bladder cancer. Study heterogeneity precluded quantitative assessment of outcomes. Obesity is potentially associated with an increased risk of bladder cancer, particularly for progression, recurrence, or death. Further studies of physical activity and bladder cancer are needed to validate these observations and elucidate the associations of exercise with bladder cancer progression and mortality.

    Conditions impairing bladder function in children and adults, such as myelomeningocele, posterior urethral valves, bladder exstrophy or spinal cord injury, often need urinary diversion or augmentation cystoplasty as when untreated they may cause severe bladder dysfunction and kidney failure. Currently, the gold standard therapy of end-stage bladder disease refractory to conservative management is enterocystoplasty, a surgical enlargement of the bladder with intestinal tissue. Despite providing functional improvement, enterocystoplasty is associated with significant long-term complications, such as recurrent urinary tract infections, metabolic abnormalities, stone formation, and malignancies. Therefore, there is a strong clinical need for alternative therapies for these reconstructive procedures, of which stem cell-based tissue engineering (TE) is considered to be the most promising future strategy. This review is focused on the recent progress in bladder stem cell research and therapy and the challenges that remain for the development of a functional bladder wall.

    Neck mechanics is central to head injury prevention since it is the musculoskeletal neck, which dictates the position and movement of the head. In the US, traumatic injury is the leading cause of death for children; however prevention is hampered by the lack of data concerning the mechanics of the immature head-and-neck. Thus, the objective of this study was to quantify neck muscle strength and endurance across the maturation spectrum and correlate these with head-and-neck anthropometry. A factorial study was performed on 91 human subjects measuring head-and-neck anthropometry and neck strength and endurance in three bending directions (flexion, extension, and lateral) as a function of age (6-23 years). Using a custom device, neck maximum voluntary contraction (MVC) force was measured in triplicate. Next, neck muscle endurance (sustained effort) was measured as the subjects' ability to maintain 70% of peak force over 30s. Linear regression of peak force and endurance as a function of age revealed each direction to significantly (pNeck muscle strength, similar between young males and females, becomes disparate in adolescence and adulthood with males exhibiting greater strength. Bending direction differences were also found with extension strength being the greatest regardless of age and sex. Furthermore, neck circumference appears predictive of neck strength and endurance in children. Together, these relationships may facilitate improved design of injury prevention interventions.

    to improve the results of advanced peritonitis management. 743 patients with advanced peritonitis were studied. Patients were divided into 2 groups depending on treatment strategy. Programmed relaparotomy combined with removable draining musculoaponeurotic seams during laparotomy closure decreased mortality from 47.8±2.7% to 24.1±2.3% (pperitonitis management. Laparotomy closure with only cutaneous seams is indicated in case of persistent abdominal hypertension. Large eventration always requires abdominal wall repair. APACHE-III scale scores have significant prognostic value in patients with advanced peritonitis.

    Since its introduction by Jennison in 1958, the closure-phase method for removing the effects of electrical path-length errors in radio astronomy and of atmospheric turbulence in optical astronomy has been based on the non-redundant-spacing triple interferometer. It is shown that through application of lucky imaging concepts it is possible to relax this condition, making closure-phase methods possible with redundantly spaced interferometer configurations and thereby widening their range of application. In particular, a quadruple-interferometer can, under lucky imaging conditions, be treated as though it were a triple interferometer. The slit-annulus aperture is investigated as a special case.

    2012-01-01

    Full Text Available Giant bladder diverticula are rare causes of bladder outlet obstruction in children and have rarely been reported. [1] In this paper, we present three children with giant bladder diverticula who presented with bladder outlet obstruction within a year. Micturating cystourethrogram is important for investigating bladder outlet obstruction in children and was used to confirm the diagnosis in all the patients. The relationship between the diverticula and ureters varied, with the ureters running either through the wall of the diverticulum and opening directly into the bladder, or opening into the diverticulum. In one patient, there was a recurrence, which was excised successfully. Excision is important to reduce the risk of recurrence.

    This study was intended to report our recent experience of bladder injuries due to gunshots in the Syrian conflict and review the literature regarding diagnosis and treatment. Twenty-two cases with abdominal and inguinal firearm wounds and bladder ruptures sustained in the Syrian conflict were reported. Age, mechanism/location of damage, associated injuries, Revised Trauma Score (RTS), Injury Severity Score (ISS), Trauma Injury Severity Score (TRISS), and complications were analyzed. The severity of the bladder injuries was classified according to the American Association for the Surgery of Trauma Organ Injury Scaling (AAST-OIS grade ?II database).The type of the bladder rupture was defined according to the classification System for Bladder Injury Based on Findings at CT Cystography. The mean age was 26 years (range, 18-36). The mean ISS was 22 (10-57), mean TRISS was 0.64 (0.004-0.95), and mean RTS was 6.97 (3.30-7.84). In the mortality group, the mean ISS, TRISS, and RTS were 48 (36-57), 0.016 (0.004-0.090), and 4.10 (3.30-4.92), respectively; whereas, the mean ISS, TRISS, and RTS were found as 21 (10-26), 0.64 (0.49-0.95), and 7.24 (5.65-7.84), respectively in the survival group (P=0.06). CT-cystography showed seventeen type 2, three type 4, and two type 5 bladder injuries. According to AAST-OIS, there were nine grade IV, six grade III, five grade II, and two grade V injuries. In war settings, when injuries are often severe and multiple surgical exploration and closure are mandatory, mortality risk is associated with high ISS and low TRISS and RTS values.

  13. Isolated neck-lifting procedure: isolated stork lift.

    Barbarino, Sheila C; Wu, Allan Y; Morrow, David M

    2013-04-01

    Many patients desire cosmetic improvement of neck laxity when consulting with a plastic surgeon about their face. Neck laxity and loss of the cervicomental angle can be due to multiple components of aging such as skin quality/elasticity, loss of platysma muscle tone, and submental fat accumulation. Traditionally, the procedure of choice for patients with an aging lower face and neck is a cervicofacial rhytidectomy. However, occasionally, a patient wishes to have no other facial surgery than an improvement of their excessive skin of the anterior, lateral, and/or posterior neck. In other instances, a patient may present with having had a face/neck-lifting procedure that left objectionable vertical/diagonal lines at the lateral neck. In both these instances, a surgeon should consider an isolated stork lift (ISL) procedure. An ISL procedure avoids and/or corrects problematic vertical/diagonal lateral neck folds by "walking" the excess skin flaps around the posterior inferior occipital hairline bilaterally, bringing the flaps together at the lateral and posterior neck, which sometimes involves a midline posterior dart excision of the dog ear. A patient presenting with excessive skin of the neck (anterior, lateral, and/or posterior) and/or residual vertical/diagonal skin folds is an excellent candidate for the ISL. The ISL procedure was performed on 273 patients over a 2-year period at The Morrow Institute. Patients were included if they had excessive skin of the anterior, lateral, and/or posterior neck and/or diagonal/vertical lateral bands and did not desire a full face-lifting procedure. Patients were excluded from this study if they would not accept having longer hair in order to cover the scar along the posterior inferior occipital hairline or a midline T-flap skin closure scar at the base of the posterior midline neck. Under a combination of local anesthesia and IV sedation, a postauricular face-lift incision was made that was extended in a circumoccipital fashion

    Full Text Available Zachary F Williams, William W Hope Department of Surgery, South East Area Health Education Center, New Hanover Regional Medical Center, Wilmington, NC, USA Abstract: This review examines both early and late wound complications following laparotomy closure, with particular emphasis on technical aspects that reduce hernia formation. Abdominal fascial closure is an area of considerable variation within the field of general surgery. The formation of hernias following abdominal wall incisions continues to be a challenging problem. Ventral hernia repairs are among the most common surgeries performed by general surgeons, and despite many technical advances in the field, incisional hernia rates remain high. Much attention and research has been directed to the surgical management of hernias. Less focus has been placed on prevention of hernia formation despite its obvious importance. This review examines the effects of factors such as the type of incision, suture type and size, closure method, patient risk factors, and the use of prophylactic mesh.

    HAMLET is a protein-lipid complex that kills different types of cancer cells. Recently we observed a rapid reduction in human bladder cancer size after intravesical HAMLET treatment. In this study we evaluated the therapeutic effect of HAMLET in the mouse MB49 bladder carcinoma model. Bladder tumors were established by intravesical injection of MB49 cells into poly L-lysine treated bladders of C57BL/6 mice. Treatment groups received repeat intravesical HAMLET instillations and controls received alpha-lactalbumin or phosphate buffer. Effects of HAMLET on tumor size and putative apoptotic effects were analyzed in bladder tissue sections. Whole body imaging was used to study HAMLET distribution in tumor bearing mice compared to healthy bladder tissue. HAMLET caused a dose dependent decrease in MB49 cell viability in vitro. Five intravesical HAMLET instillations significantly decreased tumor size and delayed development in vivo compared to controls. TUNEL staining revealed selective apoptotic effects in tumor areas but not in adjacent healthy bladder tissue. On in vivo imaging Alexa-HAMLET was retained for more than 24 hours in the bladder of tumor bearing mice but not in tumor-free bladders or in tumor bearing mice that received Alexa-alpha-lactalbumin. Results show that HAMLET is active as a tumoricidal agent and suggest that topical HAMLET administration may delay bladder cancer development.

    2016-01-01

    Many interventions for neurogenic bladder patients are directed towards improving quality of life (QOL). Patient reported outcome measures (PROMs) are the primary method of evaluating QOL, and they provide an important quantification of symptoms which can’t be measured objectively. Our goal was to review general measurement principles, and identify and discuss PROMs relevant to neurogenic bladder patients. We identify two recent reviews of the state of the literature and updated the results with an additional Medline search up to September 1, 2015. Using the previous identified reviews, and our updated literature review, we identified 16 PROMs which are used for the assessment of QOL and symptoms in neurogenic bladder patients. Several are specifically designed for neurogenic bladder patients, such as the Qualiveen (for neurogenic bladder related QOL), and the Neurogenic Bladder Symptom Score (NBSS) (for neurogenic bladder symptoms). We also highlight general QOL measures for patients with multiple sclerosis (MS) and spinal cord injury (SCI) which include questions about bladder symptoms, and incontinence PROMs which are commonly used, but not specifically designed for neurogenic bladder patients. It is essential for clinicians and researchers with an interest in neurogenic bladder to be aware of the current PROMs, and to have a basic understanding of the principals of measurement in order to select the most appropriate one for their purpose.

  20. Exogenous glycosaminoglycans coat damaged bladder surfaces in experimentally damaged mouse bladder

    Hurst Robert E

    2005-03-01

    Full Text Available Abstract Background Interstital cystitis is often treated with exogenous glycosaminoglycans such as heparin, chondroitin sulphate (Uracyst, hyaluronate (Cystistat or the semi-synthetic pentosan polysulphate (Elmiron. The mechanism of action is presumed to be due to a coating of the bladder surface to replace the normally present chondroitin sulphate and heparan sulphate lost as a result of the disease. This study used fluorescent labelled chondroitin sulphate to track the distribution of glycosaminoglycans administered intravesically to mouse bladder that had been damaged on the surface. Methods The surfaces of mouse bladders were damaged by 3 mechanisms – trypsin, 10 mM HCl, and protamine sulphate. Texas Red-labeled chondroitin sulphate was instilled into the bladders of animals with damaged bladders and controls instilled only with saline. Bladders were harvested, frozen, and sectioned for examination by fluorescence. Results The normal mouse bladder bound a very thin layer of the labelled chondroitin sulphate on the luminal surface. Trypsin- and HCl-damaged bladders bound the labelled chondroitin sulphate extensively on the surface with little penetration into the bladder muscle. Protamine produced less overt damage, and much less labelling was seen, presumably due to loss of the label as it complexed with the protamine intercalated into the bladder surface. Conclusion Glycosaminoglycan administered intravesically does bind to damaged bladder. Given that the changes seen following bladder damage resemble those seen naturally in interstitial cystitis, the mechanisms proposed for the action of these agents is consistent with a coating of damaged bladder.

  1. Intra-vesical knot of bladder catheter in an extremely low birthweight neonate: A case report

    Paula M.Y. Tang

    2015-07-01

    Full Text Available Premature and extremely low birth weight (ELBW neonates are at high risk of developing multiple co-morbidities and often require urinary catheterization for various medical indications. Intra-vesical knotting of bladder catheter is a known but uncommon complication of this procedure. We report a case of an ELBW baby boy with a knotted bladder catheter requiring surgical retrieval. After an elective operation for the closure of patent ductus arteriosus, a 4 French urinary catheter was inserted into an ELBW baby boy for urine output monitoring and left in-situ. Resistance was encountered in attempt to remove the urinary catheter. Abdominal X Ray confirmed intra-vesical knotting of the tube. Knot unravelling by interventional radiology was attempted but was unsuccessful. Open extra-peritoneal bladder exploration was performed for the retrieval of the tightly knotted catheter. A 6 French transurethral Foley catheter was inserted for bladder drainage. Upon removal of the Foley's catheter on day 5 post op, the baby was able to void spontaneously. With literature review, we postulated the potential risk factors resulting in this potentially avoidable iatrogenic unusual complication. Recommendations were suggested to avoid further incidences.

    2016-04-01

    Metabolism of bladder cancer represents a key issue for cancer research. Several metabolic altered pathways are involved in bladder tumorigenesis, representing therefore interesting targets for therapy. Tumor cells, including urothelial cancer cells, rely on a peculiar shift to aerobic glycolysis-dependent metabolism (the Warburg-effect) as the main energy source to sustain their uncontrolled growth and proliferation. Therefore, the high glycolytic flux depends on the overexpression of glycolysis-related genes (SRC-3, glucose transporter type 1 [GLUT1], GLUT3, lactic dehydrogenase A [LDHA], LDHB, hexokinase 1 [HK1], HK2, pyruvate kinase type M [PKM], and hypoxia-inducible factor 1-alpha [HIF-1α]), resulting in an overproduction of pyruvate, alanine and lactate. Concurrently, bladder cancer metabolism displays an increased expression of genes favoring the pentose phosphate pathway (glucose-6-phosphate dehydrogenase [G6PD]) and the fatty-acid synthesis (fatty acid synthase [FASN]), along with a decrease of AMP-activated protein kinase (AMPK) and Krebs cycle activities. Moreover, the PTEN/PI3K/AKT/mTOR pathway, hyper-activated in bladder cancer, acts as central regulator of aerobic glycolysis, hence contributing to cancer metabolic switch and tumor cell proliferation. Besides glycolysis, glycogen metabolism pathway plays a robust role in bladder cancer development. In particular, the overexpression of GLUT-1, the loss of the tumor suppressor glycogen debranching enzyme amylo-α-1,6-glucosidase, 4-α-glucanotransferase (AGL), and the increased activity of the tumor promoter enzyme glycogen phosphorylase impair glycogen metabolism. An increase in glucose uptake, decrease in normal cellular glycogen storage, and overproduction of lactate are consequences of decreased oxidative phosphorylation and inability to reuse glucose into the pentose phosphate and de novo fatty acid synthesis pathways. Moreover, AGL loss determines augmented levels of the serine-to-glycine enzyme

  3. Adrenergic signaling elements in the bladder wall of the adult rat.

    A growing body of work is describing the absence of a significant sympathetic innervation of the detrusor implying little sympathetic regulation of bladder contractility. However, low doses of adrenergic agonists are capable of relaxing the bladder smooth muscle. If these effects underpin a physiological response then the cellular nature and operation of this system are currently unknown. The present immunohistochemistry study was done to explore the existence of alternative adrenergic signaling elements in the rat bladder wall. Using antibodies to tyrosine hydroxylase (TH) and vesicular mono-amine transporter (vmat), few adrenergic nerves were found in the detrusor although TH immunoreactive (IR) nerves were apparent in the bladder neck. TH-IR and vmat-IR nerves were however abundant surrounding blood vessels. A population of vmat-IR cells was found within the network of interstitial cells that surround the detrusor muscle bundles. These vmat-IR cells were not or only weakly TH-IR. This suggests that these interstitial cells have the capacity to store and release catecholamines that may involve noradrenaline. Cells expressing the β1-adrenoceptor (β1AR-IR) were also detected within the interstitial cell network. Double staining with antibodies to β1AR and vmat suggests that the majority of vmat-IR interstitial cells show β1AR-IR indicative of an autocrine signaling system. In conclusion, a population of interstitial cells has the machinery to store, release and respond to catecholamines. Thus, there might exist a non-neuronal β-adrenergic system operating in the bladder wall possibly linked to one component of motor activity, micro-contractions, a system that may be involved in mechanisms underpinning bladder sensation.

    Rupture of the urinary bladder is a rare injury most often encountered after severe trauma and in conjunction with injuries to other organ systems. It may occur, however, without concomitant injury and also after minimal trauma. This diagnosis must be suspected in a patient with abdominal pain who is unable to void or who presents hematuria. The diagnosis is made by means of a retrograde cystogram using 350-400 ml contrast medium and supplemented by a drainage film. Intrapertioneal ruptures should be treated surgically by closure in layers, and drainage. Patients with extraperitoneal ruptures can safely be treated with simple catheter drainage until the rupture has healed, usually within 10-20 days. The authors report three cases of bladder rupture after minimal trauma and describe the state of the art of diagnosis and treatment of these injuries. 15 refs., 3 figs.

Chemotherapy, consisting of CDDP (40 mg/m{sup 2}, Day 1 and 8) and 5-FU (200 mg/m{sup 2}, 24-h continuous infusion through Day 1-5 and 8-12), with concurrent radiotherapy (2 Gy/day, 5 days/w) were administered and repeated 2-3 courses in every 5 weeks. Mucositis and myelo-suppression were the main side effects observed, but all of them were tolerable. Total response rate and complete response rate was 94.4% and 55.6%, respectively. Out of six patients requiring tracheotomy for airway obstruction due to bulky tumor, four achieved sufficient tumor shrinkage by the treatment and could obtain closure of the stoma. Two patients whose neck lymph nodes were still remaining after chemoradiotherapy, could obtain local control by supplemental neck dissection surgery. These regimen is feasible and effective for locally advanced head and neck cancer. (author)

    Full Text Available Tanweer Karim, Margaret Topno, Vinod Sharma, Raymond Picardo, Ankur HastirSurgery, MGM Medical College, Kamothe, Navi Mumbai, IndiaAbstract: Bladder injuries are very common in patients who have had road traffic accidents. The method of diagnosis and management of such injuries is well established and accepted. However, trauma to the bladder can be associated with other life-threatening injuries which are frequently missed, and often diagnosed during laparotomy for other reasons. The aim of this study was to diagnose bladder injury in polytrauma patients as early as possible, taking into consideration the fact that these patients are hemodynamically unstable and require rapid evaluation and management. In order to achieve our objective, we used bedside sonography with retrograde instillation of normal saline to diagnose bladder injury in addition to use of the conventional retrograde cystogram.Keywords: bladder injury, bladder rupture, retrograde cystogram

    Full Text Available Inguinal bladder hernia is a rare clinical condition, with 1–3% of all inguinal hernias involving the bladder. Any portion of the bladder may herniate, from a small portion or a diverticulum to most of the bladder. We present a 55-year-old male with an intermittent right scrotal mass of 6 months’ duration. The mass lesion protruded through the right inguinal canal before voiding and reduced after that. Scrotal sonography revealed a hypoechoic lesion in the scrotum that stretched cranially to the intra-abdominal portion of the bladder. Excretory urography showed a duplicated system in the left kidney and deviation of the left orifice to the right side of the trigon. Finally, cystography illustrated herniation of the bladder to the right scrotum. Surgical repair of the hernia was done with mesh. Follow-up cystography one month postoperatively revealed no herniation.

  9. Stabilization of membrane necks by adhesive particles, substrate surfaces, and constriction forces.

    Agudo-Canalejo, Jaime; Lipowsky, Reinhard

    2016-10-21

    Membrane remodelling processes involving the formation and fission of small buds require the formation and closure of narrow membrane necks, both for biological membranes and for model membranes such as lipid bilayers. The conditions required for the stability of such necks are well understood in the context of budding of vesicles with bilayer asymmetry and/or intramembrane domains. In many cases, however, the necks form in the presence of an adhesive surface, such as a solid particle or substrate, or the cellular cortex itself. Examples of such processes in biological cells include endocytosis, exocytosis and phagocytosis of solid particles, the formation of extracellular and outer membrane vesicles by eukaryotic and prokaryotic cells, as well as the closure of the cleavage furrow in cytokinesis. Here, we study the interplay of curvature elasticity, membrane-substrate adhesion, and constriction forces to obtain generalized stability conditions for closed necks which we validate by numerical energy minimization. We then explore the consequences of these stability conditions in several experimentally accessible systems such as particle-filled membrane tubes, supported lipid bilayers, giant plasma membrane vesicles, bacterial outer membrane vesicles, and contractile rings around necks. At the end, we introduce an intrinsic engulfment force that directly describes the interplay between curvature elasticity and membrane-substrate adhesion.

Due to its advantage of better view of the peritoneal cavity an opportunity for thorough lavage and avoidance of upper abdominal incision, with its related complication, especially in high – ri sk patients, this procedure has gained popularity all over the world. Approximately 10 - 20% of patients suffering from peptic ulcer develop perforation of stomach or duodenum in which, chemical peritonitis develop initially from gastric secretion and duoden al secretion the condition is life threatening. Early diagnosis and treatment is extremely important. Mortality will increase up if perforation exists more than 24 to 48 hours. Usually surgical intervention of simple closure with omental patch of the perforation is required. this study aims at evaluating efficacy , safety and outcome of laparoscopic surgery for perforated duodenal ulcer patients admitted during period Jan 2009 to Dec 2012 at tertiary hospital in north Karnataka A total of 61cases diagnosed as peritonitis secondary to duodenal ulcer perforation were involved in the study 30underwent open perforation closure and 31 cases underwent lap closure. Peptic ulcers are focal defects in the gastric or duodenal mucosa which extend into the sub mucosa or deeper. they may be acute or chronic and ultimately are caused by on imbalance between the action of peptic acid and mucosal defenses peptic ulcer remains a common outpatient diagnosis, but the number of elective operations for peptic ul cer disease have decreased dramatically over the past 30 decades due to the advent of H2 blockers However the incidence of emergency surgeries, and death rate associated with peptic ulcer are same

    Eight male patients on clean intermittent catheterization programs for neurogenic bladder dysfunction developed vesical calculi around pubic hairs inadvertently introduced into the bladder, acting as a nidus for incrustation. In three patients, the radiographic appearance of serpentine calcifications in the pelvis was highly consistent with calcareous deposits on strands of hair. Familiarity with this radiologic appearance should suggest the diagnosis in the appropriate clinical setting and help avoid misinterpretation of these calcifications, atypical of usual bladder stones.

The case was a spontaneous delivery in cephalic presentation from a 31-year-old gravida 3, para 3 Black woman who had been treated with isoniazid and spreptomycin up to 2 months before her delivery. Gestational age was 37 weeks when the fetus was delivered weighing 3.15 kgm. The cord had been wrapped around the fetus's neck, and breathing was delayed 2 minutes. In the nursery, the baby's general condition was poor, and congestive heart failure was diagnosed. The newborn had trieuspid insufficiency, severe heart failure, and acidosis at birth. These disappeared the next day. Hemodynamic studies when the baby was 4 hours old showed a large cone-shaped ductus arteriousus extending from the pulmonary artery but ending blindly at the aortic end.

Typical symptoms include urinary urgency, frequency, incontinence and nocturia. OAB occurs as a result of abnormal contractions of the bladder detrusor muscle caused by the stimulation of certain muscarinic receptors. Therefore, antimuscarinic agents have long been considered the mainstay of pharmacologic treatment for OAB. Currently, there are five such agents approved for the management of OAB in the United States: oxybutynin, tolterodine, trospium, solifenacin and darifenacin. This article summarizes the efficacy, contraindications, precautions, dosing and common side effects of these agents. All available clinical trials on trospium, solifenacin and darifenacin were reviewed to determine its place in therapy.Keywords: overactive bladder, urinary incontinence, pharmacologic management, antimuscarinic agents, anticholinergics

  1. Generalized Convective Quasi-Equilibrium Closure

    Science.gov (United States)

    Yano, Jun-Ichi; Plant, Robert

    2016-04-01

    Arakawa and Schubert proposed convective quasi-equilibrium as a basic principle for closing their spectrum mass-flux convection parameterization. In deriving this principle, they show that the cloud work function is a key variable that controls the growth of convection. Thus, this closure hypothesis imposes a steadiness of the cloud work function tendency. This presentation shows how this principle can be generalized so that it can also encompasses both the CAPE and the moisture-convergence closures. Note that the majority of the current mass-flux convection parameterization invokes a CAPE closure, whereas the moisture-convergence closure was extremely popular historically. This generalization, in turn, includes both closures as special cases of convective quasi-equilibrium. This generalization further suggests wide range of alternative possibilities for convective closure. In general, a vertical integral of any function depending on both large-scale and convective-scale variables can be adopted as an alternative closure variables, leading to an analogous formulation as Arakawa and Schubert's convective quasi-equilibrium formulation. Among those, probably the most fascinating possibility is to take a vertical integral of the convective-scale moisture for the closure. Use of a convective-scale variable for closure has a particular appeal by not suffering from a loss of predictability of any large-scale variables. That is a main problem with any of the current convective closures, not only for the moisture-convergence based closure as often asserted.

  2. Delayed presentation of traumatic intraperitoneal bladder rupture

    1986-03-01

    A child with urine ascites as a delayed manifestation of post-traumatic intraperitoneal bladder rupture is presented. The diagnosis was suggested by abdominal CT scan and confirmed with a cystogram. While uncommon, late presentation of intraperitoneal bladder rupture following trauma may occur from masking of a primary laceration or development of secondary rupture at the site of a hematoma in the bladder wall. Since CT may be a primary diagnostic study performed following abdominal trauma, the radiologist should be aware of CT findings suggesting bladder rupture and of the possibility of delayed presentation of this injury.

  3. Closure constraints for hyperbolic tetrahedra

    CERN Document Server

    Charles, Christoph

    2015-01-01

    We investigate the generalization of loop gravity's twisted geometries to a q-deformed gauge group. In the standard undeformed case, loop gravity is a formulation of general relativity as a diffeomorphism-invariant SU(2) gauge theory. Its classical states are graphs provided with algebraic data. In particular closure constraints at every node of the graph ensure their interpretation as twisted geometries. Dual to each node, one has a polyhedron embedded in flat space R^3. One then glues them allowing for both curvature and torsion. It was recently conjectured that q-deforming the gauge group SU(2) would allow to account for a non-vanishing cosmological constant Lambda, and in particular that deforming the loop gravity phase space with real parameter q>0 would lead to a generalization of twisted geometries to a hyperbolic curvature. Following this insight, we look for generalization of the closure constraints to the hyperbolic case. In particular, we introduce two new closure constraints for hyperbolic tetrahe...

    Ultrasonography has become extremely useful in the evaluation of masses in the head and neck. It enables us to determine the anatomic location of the masses as well as the characteristics of the tissues that compose them, thus making it possible to orient the differential diagnosis toward inflammatory, neoplastic, congenital, traumatic, or vascular lesions, although it is necessary to use computed tomography or magnetic resonance imaging to determine the complete extension of certain lesions. The growing range of interventional procedures, mostly guided by ultrasonography, now includes biopsies, drainages, infiltrations, sclerosing treatments, and tumor ablation.

    Full Text Available Aggressive fibromatosis (AF is a locally aggressive infiltrative low-grade benign tumor that accounts for approximately less than 3% of all soft tissue tumors. In the head and neck region this tumor tends to be more aggressive and associated with significant morbidity. Aggressive surgery is a viable management option and may be successfully used as a single modality treatment, or in combination with radiotherapy. We report a rare case of AF in a 38 year old female, who presented with a painless mass over the left supraclavicular fossa, extending inferiorly into the thoracic inlet, which was excised successfully in toto with the help of cardiothoracic vascular surgeon (CTVS.

    To assess the presence of early bladder abnormalities in a prenatally corrected and uncorrected animal model of Myelomeningocele (MMC). A MMC-like lesion was surgically created in 18 fetal lambs between the 60th and the 80th day of gestation. Eight of them did not undergo fetal repair (group A), three were repaired with an open two-layer closure (group B), three using BioGlue® (groupC) and four fetoscopically (group D). At term, bladders were examined macroscopically and histopathological changes were assessed using H-E and Masson Trichrome. Five animals in group A (5/8, 62%), two in group B (2/3, 66%), one in group C (1/3, 33%) and one in group D (1/4, 25%) survived. Macroscopically bladders in group A were severely dilated and showed thinner walls. Microscopically they showed a thin layer of colagenous tissue (Blue layer. BL) lying immediately subjacent to the urothelium. The muscular layers were thinner. Non compliant pattern with thick wall and low capacity was also found in the non corrected model. Group B and the control showed preservation of muscular layers and absence of BL. Groups C and D presented BL but also preservation of muscular layers. Bladder changes in a surgically-induced model of MMC can be described using histopathological data. Both extremes of bladder changes can be observed in the model. These changes were completely prevented with open fetal surgery and partially with other coverage modalities. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

    Full Text Available Waleed Al Taweel, Raouf SeyamDepartment of Urology, King Faisal Specialist Hospital and Research Center, Riyadh, Saudi ArabiaAbstract: Neurogenic bladder dysfunction due to spinal cord injury poses a significant threat to the well-being of patients. Incontinence, renal impairment, urinary tract infection, stones, and poor quality of life are some complications of this condition. The majority of patients will require management to ensure low pressure reservoir function of the bladder, complete emptying, and dryness. Management typically begins with anticholinergic medications and clean intermittent catheterization. Patients who fail this treatment because of inefficacy or intolerability are candidates for a spectrum of more invasive procedures. Endoscopic managements to relieve the bladder outlet resistance include sphincterotomy, botulinum toxin injection, and stent insertion. In contrast, patients with incompetent sphincters are candidates for transobturator tape insertion, sling surgery, or artificial sphincter implantation. Coordinated bladder emptying is possible with neuromodulation in selected patients. Bladder augmentation, usually with an intestinal segment, and urinary diversion are the last resort. Tissue engineering is promising in experimental settings; however, its role in clinical bladder management is still evolving. In this review, we summarize the current literature pertaining to the pathology and management of neurogenic bladder dysfunction in patients with spinal cord injury.Keywords: neurogenic bladder, spinal cord injury, urodynamics, intestine, intermittent catheterization

    Bladder cancer (BC) is among the most expensive oncological diseases. Any improvement in diagnosis or therapy carries a high potential for reducing costs. Fluorescence cystoscopy relies on a selective formation of Protoporphyrin IX (PpIX) or more general photoactive porphyrins (PAP) in malignant urothelium upon instillation of 5-aminolevulinic acid (5-ALA) or its hexyl-derivative h-ALA. Fluorescence cystoscopy equipment has been developed with the aim to compensate for the undesired distortion caused by the tissue optical properties by displaying the red fluorescence simultaneously with the backscattered blue light. Many clinical studies proved a high sensitivity in detecting flat carcinoma in situ and small papillary malignant tumours. As a result, recurrence rates were significantly decreased in most studies. The limitation lies in a low specificity, caused by false positive findings at inflamed bladder wall. Optical coherence tomography (OCT) is currently being investigated as a promising tool to overcome this limitation. H-ALA-PDT (8 or 16 mM h-ALA in 50 ml instillation for 1-2 h, white light source, catheter applicator) has recently been investigated in a phase I study. 17 patients were applied 100 J/cm2 (3 patients received incrementing doses of 25 - 50 - 100 J/cm2) during approx. 1 hour irradiation time in 3 sessions, 6 weeks apart. PDT was performed without any technical complications. Complete photobleaching of the PpIX-fluorescence, as intended, could be achieved in 43 of 45 PDT-sessions receiving 100 J/cm2. The most prominent side effects were postoperative urgency and bladder pain, all symptoms being more severe after 16 mM h-ALA. Preliminary evaluation shows complete response assessed at 3 months after the third PDT-session (i.e. 6 months after first treatment) in 9 of 12 patients. 2 of these patients were free of recurrence until final follow-up at 84 weeks.

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

    Saaby, Marie-Louise

    2014-02-01

    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

    There is a considerable discrepancy between the number of identified occupational-related bladder cancer cases and the estimated numbers particularly in emerging nations or less developed countries where suitable approaches are less or even not known. Thus, within a project of the World Health Organisation Collaborating Centres in Occupational Health, a questionnaire of the Dortmund group, applied in different studies, was translated into more than 30 languages (Afrikaans, Arabic, Bengali, Chinese, Czech, Dutch, English, Finnish, French, Georgian, German, Greek, Hindi, Hungarian, Indonesian, Italian, Japanese, Kannada, Kazakh, Kirghiz, Korean, Latvian, Malay, Persian (Farsi), Polish, Portuguese, Portuguese/Brazilian, Romanian, Russian, Serbo-Croatian, Slovak, Spanish, Spanish/Mexican, Tamil, Telugu, Thai, Turkish, Urdu, Vietnamese). The bipartite questionnaire asks for relevant medical information in the physician's part and for the occupational history since leaving school in the patient's part. Furthermore, this questionnaire is asking for intensity and frequency of certain occupational and non-occupational risk factors. The literature regarding occupations like painter, hairdresser or miner and exposures like carcinogenic aromatic amines, azo dyes, or combustion products is highlighted. The questionnaire is available on www.ifado.de/BladderCancerDoc.

    The feasibility of developing bladder cancer detection methods using intrinsic tissue optical properties is the focus of this investigation. In vitro experiments have been performed using polarized elastic light scattering in combination with tissue autofluorescence in the NIR spectral region under laser excitation in the green and red spectral regions. The experimental results obtained from a set of tissue specimens from 25 patients reveal the presence of optical fingerprint characteristics suitable for cancer detection with high contrast and accuracy. These photonic methods are compatible with existing endoscopic imaging modalities which make them suitable for in-vivo application.

    Somatic instability at microsatellite repeats was detected in 6 of 200 transitional cell carcinomas of the bladder. Instabilities were apparent as changes in (GT)n repeat lengths on human chromosome 9 for four tumors and as alterations in a (CAG)n repeat in the androgen receptor gene on the X...... chromosome for three tumors. Single locus alterations were detected in three tumors, while three other tumors revealed changes in two or more loci. In one tumor we found microsatellite instability in all five loci analyzed on chromosome 9. The alterations detected were either minor 2-base pair changes...

    The authors reviewed 227 new bladder cancers from two main hospitals in Beirut Lebanon. They analyzed the morphologic features of these tumours, insisting particularly on the number, the size, the site, the grade, the stage, the mode of spread and the vascular permeation. The latter four factors appear to be directly related to the metastatic spread of these tumours. The metastatic patterns are summarized, regional lymph node metastases being the main problem because of therapeutic implications (radical surgery, radiotherapy and chemotherapy). The problems of generalized carcinoma, unusual lymph node metastases and solitary distant metastases are also considered.

    Full Text Available Carcinoma of gall bladder has early lymphatic and haematogenous spread. Most common extra abdominal site of metastasis is the lung. Metastasis to breast from carcinoma of breast is very rare. Our case describes an interesting case of carcinoma of gall bladder metastising to breast. A 50-year-old female presented to our outpatient department with a small nodule on upper outer quadrant of left breast. Patient had a history of cholecystectomy done for symptomatic gall stones 2 years back. Histopathological examination of the gall bladder specimen showed adenocarcinoma of the gall bladder with invasion to lamina propria. No additional treatment was offered to the patient. The breast nodule was excised and sent for histopathological examination. Histopathological examination revealed metastising adenocarcinoma. Patient was subjected to palliative chemotherapy (Gamcitabine and carboplatin. However, patient died of hepatic encephalopathy after 5 months. Our case reports an unusual site of metastasis from carcinoma of gall bladder which is very rare.

    NOTCH signaling suppresses tumor growth and proliferation in several types of stratified epithelia. Here, we show that missense mutations in NOTCH1 and NOTCH2 found in human bladder cancers result in loss of function. In murine models, genetic ablation of the NOTCH pathway accelerated bladder tumorigenesis and promoted the formation of squamous cell carcinomas, with areas of mesenchymal features. Using bladder cancer cells, we determined that the NOTCH pathway stabilizes the epithelial phenotype through its effector HES1 and, consequently, loss of NOTCH activity favors the process of epithelial-mesenchymal transition. Evaluation of human bladder cancer samples revealed that tumors with low levels of HES1 present mesenchymal features and are more aggressive. Together, our results indicate that NOTCH serves as a tumor suppressor in the bladder and that loss of this pathway promotes mesenchymal and invasive features.

    We investigate the generalization of loop gravity's twisted geometries to a q-deformed gauge group. In the standard undeformed case, loop gravity is a formulation of general relativity as a diffeomorphism-invariant SU(2) gauge theory. Its classical states are graphs provided with algebraic data. In particular, closure constraints at every node of the graph ensure their interpretation as twisted geometries. Dual to each node, one has a polyhedron embedded in flat space {{{R}}3}. One then glues them, allowing for both curvature and torsion. It was recently conjectured that q-deforming the gauge group SU(2) would allow us to account for a non-vanishing cosmological constant Λ \

    This paper describes a presumptive mechanism for the development of changes in respiratory function due to chronic neck pain. The patient with neck pain presents a number of factors that could constitute a predisposition of leading to a respiratory dysfunction: (a) the decreased strength of deep neck flexors and extensors, (b) the hyperactivity and increased fatigability of superficial neck flexors, (c) the limitation of range of motion, (d) the decrease in proprioception and disturbances in neuromuscular control, (e) the existence of pain and (f) the psychosocial influence of dysfunction. The possible connection of neck pain and respiratory function could have a great impact on various clinical aspects notably patient assessment, rehabilitation and pharmacological prescription.

    The 100-D Ponds is a Treatment, Storage, and Disposal (TSD) unit on the Hanford Facility that received both dangerous and nonregulated waste. This Closure Plan (Rev. 1) for the 100-D Ponds TSD unit consists of a RCRA Part A Dangerous Waste Permit Application (Rev. 3), a RCRA Closure Plan, and supporting information contained in the appendices to the plan. The closure plan consists of eight chapters containing facility description, process information, waste characteristics, and groundwater monitoring data. There are also chapters containing the closure strategy and performance standards. The strategy for the closure of the 100-D Ponds TSD unit is clean closure. Appendices A and B of the closure plan demonstrate that soil and groundwater beneath 100-D Ponds are below cleanup limits. All dangerous wastes or dangerous waste constituents or residues associated with the operation of the ponds have been removed, therefore, human health and the environment are protected. Discharges to the 100-D Ponds, which are located in the 100-DR-1 operable unit, were discontinued in June 1994. Contaminated sediment was removed from the ponds in August 1996. Subsequent sampling and analysis demonstrated that there is no contamination remaining in the ponds, therefore, this closure plan is a demonstration of clean closure.

    Full Text Available Background. Lymphoma of the urinary bladder (LUB is rare. Aims. To review the literature on LUB. Methods. Various internet databases were used. Results. LUB can be either primary or secondary. The tumour has female predominance; most cases occur in middle-age women. Secondary LUB occurs in 10% to 25% of leukemias/lymphomas and in advanced-stage systemic lymphoma. Less than 100 cases have been reported. MALT typically affects adults older than 60 years; 75% are female. Diffuse large B-cell lymphoma is also common and may arise from transformation of MALT. LUB presents with haematuria, dysuria, urinary frequency, nocturia, and abdominal or back pain. Macroscopic examination of LUBs show large discrete tumours centred in the dome or lateral walls of the bladder. Positive staining of LUB varies by the subtype of lymphoma; B-cell lymphomas are CD20 positive. MALT lymphoma is positively stained for CD20, CD19, and FMC7 and negatively stained for CD5, CD10, and CD11c. LUB stains negatively with Pan-keratin, vimentin, CK20, and CK7. MALT lymphoma exhibits t(11; 18(q21: 21. Radiotherapy is an effective treatment for the MALT type of LUB with no recurrence. Conclusions. LUB is diagnosed by its characteristic morphology and immunohistochemical characteristics. Radiotherapy is a useful treatment.

    In a retrospective case-control study, structural characteristics of hospitals that closed during the years 1976-1980 were contrasted with three comparison groups: hospitals that were acquired in a merger; hospitals that joined a multihospital system; and hospitals that remained autonomously opened, to investigate these characteristics as predictors of closure. Characteristics investigated included environmental, structural, and process variables. The independent variables were measured 5 years prior to outcome. Findings indicate that closed hospitals resemble hospitals acquired in a merger ("failure"), and likewise autonomous hospitals resemble hospitals that join a multihospital system ("success"). The most important predictors of hospital failure were the physician-to-population ratio, the East North Central and West North Central census regions, the level of diversification, low occupancy rate, location in a standard metropolitan statistical area, the chief executive officer's lack of affiliation in the American College of Hospital Administrators, profit status, bed size of less than 50, and presence in a state with a rate-setting agency. Surprisingly, this study shows the bed-to-population ratio to be unrelated to closure. In addition, the findings strongly support the open-system perspective, which, unlike the closed-system perspective, is concerned with the vulnerability of the organization to the uncontrollable and often unpredictable influences of the environment.

  16. Influence of behavior modification on overactive bladder.

    Science.gov (United States)

    Burgio, Kathryn L

    2002-11-01

    Behavioral interventions have been used for decades to treat urge incontinence and other symptoms of overactive bladder. Perhaps the earliest form of treatment was the bladder drill, an intensive intervention designed to increase the interval between voids to establish a normal frequency of urination and normalization of bladder function. Bladder training is a modification of bladder drill that is conducted more gradually on an outpatient basis and has resulted in significant reduction of incontinence in older, community-dwelling women. Multicomponent behavioral training is another form of behavioral treatment that includes pelvic floor muscle training and exercise. This intervention focuses less on voiding habits and more on altering the physiologic responses of the bladder and pelvic floor muscles. Using biofeedback or other teaching methods, patients learn strategies to inhibit bladder contraction using pelvic floor muscle contraction and other urge suppression strategies. Although behavioral and drug therapies are known to be highly effective for reducing urge incontinence, few patients are cured with either treatment alone. Thus, future research should explore ways to enhance the effectiveness of these conservative therapies. Although the mechanisms by which behavioral treatments work have not been established, there is some evidence that behavioral and drug interventions may operate by different mechanisms, suggesting that they may have additive effects and that combining them may result in better outcomes. Future research needs to examine the mechanisms by which these therapies reduce incontinence and whether combining behavioral and drug treatment will result in better outcomes than either therapy alone.

    A 10-year-old cat was presented with a history of inappetence, pyrexia and weight loss. Clinical investigations showed anaemia, hyperbilirubinaemia, septic peritonitis and a double gall bladder with choleliths in an extrahepatic duct. Initial medical stabilisation was performed. At laparotomy, a duplex gall bladder with two separate cystic ducts was identified. The left gall bladder was thickened and had ruptured at the apex. Multiple choleliths were identified in the left cystic duct. The right gall bladder and cystic duct were grossly normal. The ruptured gall bladder was repaired, the gallstones were removed via a choledochotomy of the left cystic duct and a choledochoduodenostomy was created from the dilated left cystic duct. The cat remained depressed and anorexic, and it was euthanased 72 hours postoperatively at the owners' request. This is the first ante-mortem investigation of extrahepatic biliary disease associated with gall bladder duplication in the cat.

  19. Photodynamic therapy: applications in bladder cancer and other malignancies.

    Science.gov (United States)

    Chang, S C; Bown, S G

    1997-11-01

    Photodynamic therapy (PDT) has gained popularity in the past 10 years because of advances in laser and pharmacokinetic technologies and the development of new photosensitizers. Early studies on PDT with focal illumination for papillary bladder cancer obtained reasonable response rates for small tumors but recurrence was common. Whole bladder irradiation, once a suitable light-delivery system had been developed, gave promising outcomes with acceptable rates of complications. PDT for prostate cancer is still at the experimental stage but initial results have been promising. Clinical trials of PDT for brain tumors have shown no significant complications but no improvement in survival rate compared with other treatment modalities. PDT is particularly useful for early superficial lung cancers that are localized to one or a few discrete sites; it is also safe to use in patients who are too sick to be treated with conventional therapies. Preoperative PDT has reduced the extent of surgery necessary in some patients. Clinical experience with PDT for gynecological cancer is limited and prospective studies are needed. In head and neck oncology, PDT should prove a useful option, but methodological problems need to be overcome. Good responses of esophageal cancer to PDT have led to governmental approval of Photofrin, a photosensitizer, in several countries for either palliative use or treatment of inoperable or recurrent cancer. The use of PDT for early gastric cancer has great potential but several technical problems remain. PDT has proven generally effective for skin cancer when hematoporphyrin derivative or Photofrin is used but more long-term follow-up data are required for PDT with 5-aminolevulinic acid. Overall, PDT is changing from a scientific curiousity into an accepted modality for the treatment of cancer, with an improved likelihood of finding further clinical applications.

    An 83-year-old woman was admitted to the department of gastroenterology in our hospital with a diagnosis of adhesive ileus following operation for a uterine cancer on July 22, 1997. Conservative therapy was started, but three days later, peritoneal signs appeared and white blood cell count and CRP level increased. An emergency operation was performed. Upon laparotomy, there were a large volume of ascites and a rupture of the bladder of which wall had become fragile. It was thought that the cause of rupture might result from radiation cystitis because she received irradiation after operation for the uterine cancer. Ruptured site of the bladder was sutured. Possible causes of the ileus were thought to be intestinal paralysis due to generalized peritonitis and a narrowing of the ileum where inflammatory change was remarkable. For this, an excision of the ileum with ileostomy was performed. Thereafter a closure of the ileostomy and ileocolostomy were carried out. The patient had difficulty in management of evacuation for a while, but she was discharged on March 2, 1998. Spontaneous rupture of the bladder is rare. This paper presents such a rare case caused by radiation cystitis, together with 14 cases reported in Japan. It is thought that surgeons who manage acute abdomen may encounter the disease. (author)

    Full Text Available Bladder rupture is a rare condition associated with significant morbidityand mortality. It is classified into traumatic, nontraumatic or idiopathic andspontaneous. The nonspecific initial clinical presentation is followed bydiscomfort in the lower abdomen, oliguria, hematuria and ascitis. Laboratoryabnormalities simulate the picture of acute renal failure and occurs by amechanism called auto reverse dialysis, with absorption of excreta throughthe peritoneal membrane. The authors describe a case of bladder rupturein morphologically and functionally normal urinary bladder associated withalcohol intake in young healthy man, manifested by abdominal discomfort,pseudo renal failure and massive ascitis. The diagnosis was made by anabdominal multidetector computed tomography confirmed by the finding of7 cm laceration at laparotomy.

    The article analyzes the causes of hyperactive detrusory contractions, considered etiopathogenesis and treatment of patients with overactive bladder syndrome (OBS). Two groups of patients with overactive bladder syndrome were examined, analyzed etiology, pathogenesis and treatment. A new method for increasing the threshold sensitivity of spinal centers under the OBS by using the local lesions of the mucous membrane of the bladder by electrical coagulation or local microwave hyperthermia of the prostate are proposed. The high efficiency of these methods in dealing with OBS is shown.

This case report highlights the importance of a fast ophthalmologic evaluation in diseases with ocular involvement in order to make accurate diagnoses and appropriate treatments.

  10. Successful closure of feline axillary wounds by reconstruction of the elbow skin fold.

    Science.gov (United States)

    Brinkley, C H

    2007-02-01

    This report describes the successful closure of five chronic feline axillary wounds. The aetiology was known to be forelimb entrapment in a neck collar in three cases and was suspected in the others. Each cat underwent a single surgical procedure during which the wound was debrided, the normal structure of the elbow skin fold was restored and the remaining skin defect was closed primarily. None of the cats had undergone any previous reconstruction attempts. No postoperative complications were observed and the wounds healed uneventfully. Cats have well-developed elbow skin folds, allowing a wide range of limb motion to occur. Having a forelimb trapped in a neck collar not only creates a wound in the axilla but also disrupts the normal anatomy of the skin fold. This report demonstrates that restoring the elbow skin fold before closing the wound may improve the chances of a successful reconstruction at the first surgical intervention.

    Deep neck infection has a high morbidity and mortality and the extent of infection is often difficult to estimate clinically. The complex anatomy and the communication between neck spaces means that infection can spread along fascial planes leading to life-threatening complications such as airway compromise, vascular erosion/thrombosis, neural dysfunction, and ultimately descending necrotizing mediastinitis. Imaging has an important role to play in identifying the extent of infection and the presence of complications.

    Full Text Available Lamise Z Rajjoub, Nisha Chadha, David A Belyea Department of Ophthalmology, The George Washington University, Washington, DC, USA Abstract: This is a case report describing recurrent intermittent acute angle closure episodes in the setting of topiramate use in a female suffering from migraines. Despite laser peripheral iridotomy placement for the pupillary block component, and the discontinuation of topiramate, the acute angle closure did not resolve in the left eye with chronic angle closure and the patient required urgent trabeculectomy. The right eye responded to laser peripheral iridotomy immediately and further improved after the cessation of topiramate. While secondary angle closure glaucoma due to topiramate use has been widely reported, its effects in patients with underlying primary angle closure glaucoma have not been discussed. Our report highlights the importance of recognizing the often multifactorial etiology of angle closure glaucoma to help guide clinical management.

    2010-12-14

    A closure for a microreactor includes a cap that is configured to be inserted into a well of the microreactor. The cap, or at least a portion of the cap, is compliant so as to form a seal with the well when the cap is inserted. The cap includes an aperture that provides an airway between the inside of the well to the external environment when the cap is inserted into the well. A porous plug is inserted in the aperture, e.g., either directly or in tube that extends through the aperture. The porous plug permits gas within the well to pass through the aperture while preventing liquids from passing through to reduce evaporation and preventing microbes from passing through to provide a sterile environment. A one-way valve may also be used to help control the environment in the well.

We reported three cases of bladder tumours in vesical diverticula, with delay of diagnosis two, eight and twelve months respectively. The radiology exploration suspected the diagnosis and the histology biopsy confirmed a diagnosis of primary transitional cell carcinoma in two cases: PTa GI and T2 GII, and in an other case it was a invasive epidermoid carcinoma. The first patient was dead by urethral resection of the bladder tumour. The second required a cytoprototectomy and the last patient. The treatment consisted of radiotherapy and chemotherapy. We insisted of the particularity diagnosis, histology and therapeutic for bladder tumour in vesical diverticula and the early diagnosis in order to have a good prognosis.

    Full Text Available Carcinoma of the bladder is a disease of the elderly. Bladder cancer is three times more common in males than in females and more common in whites than in blacks. Patients with bladder cancer have a 1% to 4% incidence of synchronous or metachronous upper t ract urothelial tumors. There are many risk factors for urothelial cancer, classified into (1 Genetic (2 chemical exposure, and (3 chronic irritation. Genetic abnormalities associated with CIS include alterations in the retinoblastoma gene (Rb, p53, an d PTEN. Chemical exposure has the most epidemiologic evidence to support it as an inciting agent (Aromatic amines, aniline dyes, and nitrites and nitrates. Chronic irritants include catheters, recurrent urinary track infections, Schistosoma haematobium, a nd irradiation. There are many studies that suggest high water consumption, vitamin intake, and various diets that are beneficial in preventing bladder cancer. However, none of these have shown any clear benefit with respect to prevention.

    ABSTRACT Objective Cystometric evaluation of the bladder after autotransplant and isogeneic transplant in female rats. Material and Methods Two groups were constituted: (A) bladder autotransplant with two subgroups: R1 – (control) and R2 – (bladder transplant); (B) isogeneic bladder transplant with three subgroups; T1 – (control); T2–T3, two subgroups observed for 30 and 60 days after transplant, respectively. All animals underwent cystometric evaluation. Afterwards, the bladders were removed for histological study. Results The transplanted bladders did not show significant changes in filling/storage and emptying/micturition functions after 30 and 60 days of evolution. Upon macroscopical evaluation, there was good revascularization and the tissue was well preserved. Cystometry results: Did not show significant differences in the micturition pressure in subgroups T2-T3, but did between subgroups R1−R2, T1−T2, and T1−T3. Significant differences were verified in the micturition interval between T1−T3, T2−T3, but not between R1−R2, T1−T2. There was significant difference in the micturition duration between T1−T3 but not between R1−R2, T1−T2 and T2−T3. No fistula was noted on the suture site nor leakage of urine in the abdominal cavity or signs of necrosis or retraction were observed. Conclusions Transplant of the bladder was shown to be a viable procedure. The results indicate that there was structural and functional regeneration of transplanted bladders, and these results indicate that it is possible that vascular endothelium growth and neurogenesis factors are involved and activated in the process of the preservation or survival of the transplanted organ.

    1998-07-01

    Although the overall incidence of bladder calculi has been decreasing, it is still a significant disease affecting adults and children. Prior treatment options have included open cystolitholapaxy, blind lithotripsy, extracorporeal shock wave lithotripsy, and visual lithotripsy with ultrasonic or electrohydraulic probes. The holmium laser has been found to be extremely effective in the treatment of upper tract calculi. This technology has also been applied to the treatment of bladder calculi. We report our experience with the holmium laser in the treatment of bladder calculi. Twenty- five patients over a year and a half had their bladder calculi treated with the Holmium laser. This study was retrospective in nature. Patient demographics, stone burden, and intraoperative and post-operative complications were noted. The mean stone burden was 31 mm with a range of 10 to 60 mm. Preoperative diagnosis was made with either an ultrasound, plain film of the abdomen or intravenous pyelogram. Cystoscopy was then performed to confirm the presence and determine the size of the stone. The patients were then taken to the operating room and given a regional or general anesthetic. A rigid cystoscope was placed into the bladder and the bladder stone was then vaporized using the holmium laser. Remaining fragments were washed out. Adjunctive procedures were performed on 10 patients. These included transurethral resection of the prostate, transurethral incision of the prostate, optic internal urethrotomy, and incision of ureteroceles. No major complications occurred and all patients were rendered stone free. We conclude that the Holmium laser is an effective and safe modality for the treatment of bladder calculi. It was able to vaporize all bladder calculi and provides a single modality of treating other associated genitourinary pathology.

    Full Text Available The paper reviews the literature related to the investigations of neck pain (cervicalgia in patients with headache (cephalalgia. Neck pain is second to lower back pain as a reason for considerable socioeconomic damage to society. The prevalence of cervicalgia in the population ranges from 5.9 to 38%; the annual incidence is 10.4–21.3%; 14.2 to 71% of people report to have neck pain at some time in their lifetime. Neck pain is concurrent with cephalalgia in 70% of cases. In patients with cervicalgia, the prevalence of headache is 20–40% higher than in those with musculoskeletal pain at another site. Neck pain is as a major risk factor for migraine and tension headache (TH. Neck pain in TH progresses with the increased intensity, frequency, and strength of headache. There is a direct relationship of the quality of life worsening associated withcervicalgia to the frequency of migraine attacks and the risk of its chronization. Neck pain is noted in cervicogenic headache belonging to secondary headaches. The identification of mixed headache in a patient with cervicalgia allows the prescription of a treatment option that may be effective in relieving both headache and neck pain. The paper discusses the causes and pathogenesis of cervicalgia in patients with headache, examination methods, and main approaches to drug and nondrug therapies in relation to the leading pathophysiological mechanism, as well as new possibilities for the effective and safe relief of pain syndrome in this category of patients. Nonsteroidal anti-inflammatory drugs, myorelaxants,and their combination are observed to be effective in treating patients with cervicalgia and cephalalgia.

    Bladder augmentation (also called augmentation cystoplasty) refers to a number of surgical methods that increase the capacity and compliance of the urinary bladder. Imaging has an important role in the postoperative evaluation of bladder augmentation. The most common augmentation procedures utilize enteric segments to augment the bladder. The various types of bladder augmentation have characteristic appearances on different imaging modalities. Spontaneous bladder perforation is a complication that is seen in both early and late post-operative periods and it is one of the most important complications for radiologists to be aware of as it is life-threatening. We review the indications for bladder augmentation in children, the surgical techniques employed, the normal postoperative appearances on imaging studies and the role of imaging complications of bladder augmentation including delayed spontaneous bladder rupture, which is life-threatening.

    Full Text Available Background: Urinary bladder diseases constitute an important source of clinical signs and symptoms which are more disabling than lethal. The prevalence of bladder tumor in developed countries is approximately six times higher compared with that in developing countries. The aim of this study was to find out various lesions in urinary bladder biopsies and its frequencies.Materials and Methods: This was a five year retrospective study from January 2008 to December 2013, carried out at B&B Hospital, Lalitpur. All the relevant data of 324 patients who had undergone cystoscopic biopsy of urinary bladder were included in the study. All blocks were retrieved and stained with Hematoxylin and Eosin stain and examined under light microscope.Results: The spectrum of pathological lesions included inflammations and tumors. Non-neoplastic lesions were predominant (61.11% followed by Transitional cell tumors accounted for 124 cases (38.27%. Non-neoplastic lesions comprises of cystitis and tuberculosis. Papillary urothelial neoplasms was the most common tumors seen in this study with 55 low grade, and 54 high grade Papillary urothelial carcinoma according to recent WHO grading. Single cases each of adenocarcinoma and paraganglioma were diagnosed.Conclusion: Cystoscopic biopsies help in the early diagnosis and treatment of various bladder lesions. Analysis of cystoscopic biopsies was done to ascertain the type of urinary bladder lesions in our country.Journal of Pathology of Nepal (2015 Vol. 5, 717-719

    Full Text Available OBJECTIVE: Assessed the usefulness of virtual cystoscopy performed with multidetector computed tomography (CT in patients with different urinary bladder pathologies compared to the conventional cystoscopy. MATERIALS AND METHODS: Eighteen patients with different bladder pathologies, which consisted of 11 tumors, 3 diverticula, 2 trabecular changes and 2 stones, were assessed with conventional cystoscopy and virtual CT cystoscopy. The results of virtual CT cystoscopy were compared with the findings of conventional cystoscopy. We determined the detection rate and positive predictive value of CT imaging based virtual cystoscopy in the diagnosis of urinary bladder lesions. RESULTS: CT scanning was well tolerated by all patients, and no complications occurred. Images in 16 (88% of the 18 virtual cystoscopic examinations were either of excellent or good quality. All tumors except one, 2 trabecular changes and 2 stones were characterized with similar findings in the both of methods. The masses ranged from 0.4 to 7.0 cm in diameter. While conventional cystoscopy could not evaluate interior part of the diverticulum, virtual CT cystoscopy could demonstrate clearly within it. There were no false-positive findings in our series. CONCLUSION: Virtual CT cystoscopy is a promising technique to be used in the detection of bladder lesions. It should be considered especially at the evaluation of bladder diverticula. In the future, it may be possible or even advantageous to incorporate into the imaging algorithm for evaluation of bladder lesion.

    2009-01-01

    Segmentation of the bladder in computerized tomography (CT) images is an important step in radiation therapy planning of prostate cancer. We present a new segmentation scheme to automatically delineate the bladder contour in CT images with three major steps. First, we use the mean shift algorithm to obtain a clustered image containing the rough contour of the bladder, which is then extracted in the second step by applying a region-growing algorithm with the initial seed point selected from a line-by-line scanning process. The third step is to refine the bladder contour more accurately using the rolling-ball algorithm. These steps are then extended to segment the bladder volume in a slice-by-slice manner. The obtained results were compared to manual segmentation by radiation oncologists. The average values of sensitivity, specificity, positive predictive value, negative predictive value, and Hausdorff distance are 86.5%, 96.3%, 90.5%, 96.5%, and 2.8 pixels, respectively. The results show that the bladder can be accurately segmented.

    1981-06-01

    Tension cracks are a major surface disturbance resulting from subsidence and differential settlement above underground coal mines. Recent engineering studies of subsidence indicate that cracks may close where tensile stresses causing the cracks are reduced or relaxed. This stress reduction occurs as mining in the area is completed. Crack closure was confirmed by a study in the Wasatch Plateau coal field of central Utah. Cracks occurred in both exposed bedrock and regolith in an area with maximum subsidence of 3 m. Mean closure rate was 0.3 cm per week with individual crack closure rates between 0.2 cm and 1.0 cm per week. The mean crack closure magnitude was 80% with closure magnitudes varying between 31% and 100%. Actual magnitude values ranged from 0.6 cm to 6.5 cm with a mean value of 3.8 cm. Statistical analysis compared width change status among cracks over time. It was found that: 1) a 41% probability existed that a crack would exhibit decreasing width per weekly measurement, 2) closure state sequences seem random over time, and 3) real differences in closure state sequence existed among different cracks.

    2017-08-01

    Carefully accounting for neutrino transport is an essential component of many astrophysical studies. Solving the full transport equation is too expensive for most realistic applications, especially those involving multiple spatial dimensions. For such cases, resorting to approximations is often the only viable option for obtaining solutions. One such approximation, which recently became popular, is the M1 method. It utilizes the system of the lowest two moments of the transport equation and closes the system with an ad hoc closure relation. The accuracy of the M1 solution depends on the quality of the closure. Several closures have been proposed in the literature and have been used in various studies. We carry out an extensive study of these closures by comparing the results of M1 calculations with precise Monte Carlo calculations of the radiation field around spherically symmetric protoneutron star models. We find that no closure performs consistently better or worse than others in all cases. The level of accuracy that a given closure yields depends on the matter configuration, neutrino type and neutrino energy. Given this limitation, the maximum entropy closure by Minerbo on average yields relatively accurate results in the broadest set of cases considered in this work.

  17. What is the correct staging and treatment strategy for locally advanced prostate cancer extending to the bladder?

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available In locally advanced prostate cancer with bladder invasion, frequently encountered problems such as bleeding, urinary retention, hydronephrosis, and pain create distress for the patients. Therefore patients’ quality of life is disrupted and duration of hospitalization is prolonged. Relevant literature about accurate staging and treatment of locally advanced prostate cancer with bladder invasion was investigated. Locally advanced prostate cancer can present as a large-volume aggressive tumor extending beyond boundaries of prostate gland, and involving neighboring structures which can be involved as recurrence(s following initial local therapy. Survival times of these patients can range between 5 and 8 years. Their common characteristics are adverse and severe local symptoms unfavorably affecting quality of life Control of local symptoms and their effective palliation are independent clinical targets influencing survival outcomes of these patients. The treatment outcomes of locally advanced prostate cancer into the bladder are currently debatable. Although in the current TNM classification, it is defined in T4a, we think that this may be categorized as a subgroup of T3 and thus encourage surgeons for the indication of radical surgeries (radical prostatectomy, radical cystoprostatectomy in selected patient populations after discussing issues concerning consequences of the treatment alternatives, and expectations with the patients. Cystoprostatectomy followed by immediate androgen deprivation therapy may be a feasible option for selected patients with previously untreated prostate cancer involving the bladder neck because of excellent local control and long term survival.

    Gall bladder cancer (GBC) has one of the poorestoutcomes of all cancers. Early GBC is difficult todiagnose on even computed tomography. GB has nosubmucosa and the cancer infiltrates directly into themuscularis propria. GB wall is thin and important adjacentorgans viz. liver, duodenum and pancreas get easilyinfiltrated. Tumor in the GB neck often needs extendedright hepatectomy. Infiltration of duodenum/pancreasmay necessitate pancreato-duodenectomy or evenhepato-pancreato-duodenectomy. Mortality of surgicalprocedures, when performed for GBC, is higher thanwhen performed for other cancers. Survival in GBC,even after R0 resection, is poor. There is no proven roleof neo-adjuvant or adjuvant therapy for loco-regionallyadvanced GBC. There is no role of palliative surgeryin metastatic GBC. Early GBC is diagnosed incidentallyafter cholecystectomy for stones and requires reoperationfor completion extended cholecystectomy butunfortunately, most surgeons are not aware of this. GBChas a peculiar epidemiology and is uncommon in theWest and has, therefore, not received much attention.Preventive cholecystectomy for asymptomatic stonesis not recommended and there is no serum marker forscreening. With all factors pitched against it, it doesappear that GBC is a bad cancer per se !

    Full Text Available Background: Work in voiding (WIV of the bladder may be used to evaluate bladder status throughout urination rather than at a single time point. Few studies, however, have assessed WIV owing to the complexity of its calculations. We have developed a method of calculating work capacity of the bladder while voiding and analyzed the associations of bladder work parameters with bladder contractile function and bladder outlet obstruction (BOO. Methods: The study retrospectively evaluated 160 men and 23 women, aged >40 years and with a detrusor pressure at maximal flow rate (P det Q max of ≥40 cmH 2 O in men, who underwent urodynamic testing. The bladder power integration method was used to calculate WIV; WIV per second (WIV/t and WIV per liter of urine voided (WIV/v were also calculated. In men, the relationships between these work capacity parameters and P det Q max and Abrams-Griffiths (AG number were determined using linear-by-linear association tests, and relationships between work capacity parameters and BOO grade were investigated using Spearman′s association test. Results: The mean WIV was 1.15 ± 0.78 J and 1.30 ± 0.88 J, mean WIV/t was 22.95 ± 14.45 mW and 23.78 ± 17.02 mW, and mean WIV/v was 5.59 ± 2.32 J/L and 2.83 ± 1.87 J/L in men and women, respectively. In men, WIV/v showed significant positive associations with P det Q max (r = 0.845, P = 0.000, AG number (r = 0.814, P = 0.000, and Schafer class (r = 0.726, P = 0.000. Conversely, WIV and WIV/t showed no associations with P det Q max or AG number. In patients with BOO (Schafer class > II, WIV/v correlated positively with increasing BOO grade. Conclusions: WIV can be calculated from simple urodynamic parameters using the bladder power integration method. WIV/v may be a marker of BOO grade, and the bladder contractile function can be evaluated by WIV and WIV/t.

    Bladder calculus is associated with chronic irritation and inflammation. As there is substantial documentation that inflammation can play a direct role in carcinogenesis, to date the relationship between stone formation and bladder cancer (BC) remains unclear. This study aimed to examine the association between BC and prior bladder calculus using a population-based dataset. This case-control study included 2,086 cases who had received their first-time diagnosis of BC between 2001 and 2009 and 10,430 randomly selected controls without BC. Conditional logistic regressions were employed to explore the association between BC and having been previously diagnosed with bladder calculus. Of the sampled subjects, bladder calculus was found in 71 (3.4%) cases and 105 (1.1%) controls. Conditional logistic regression analysis revealed that the odds ratio (OR) of having been diagnosed with bladder calculus before the index date for cases was 3.42 (95% CI = 2.48-4.72) when compared with controls after adjusting for monthly income, geographic region, hypertension, diabetes, coronary heart disease, and renal disease, tobacco use disorder, obesity, alcohol abuse, and schistosomiasis, bladder outlet obstruction, and urinary tract infection. We further analyzed according to sex and found that among males, the OR of having been previously diagnosed with bladder calculus for cases was 3.45 (95% CI = 2.39-4.99) that of controls. Among females, the OR was 3.05 (95% CI = 1.53-6.08) that of controls. These results add to the evidence surrounding the conflicting reports regarding the association between BC and prior bladder calculus and highlight a potential target population for bladder cancer screening.

    To review pharmacologic, pharmacokinetic, efficacy, and safety data for fesoterodine and determine its role in the treatment of overactive bladder. A MEDLINE search (1966-July 2009) was conducted using the key words fesoterodine, tolterodine, muscarinic receptor antagonist, anticholinergic, overactive bladder, urge incontinence, efficacy, safety, adverse effect, pharmacology, pharmacokinetic, and receptor binding. All articles written in English that were identified from the data sources were evaluated, prioritizing randomized, controlled trials with human data. The references of published articles that we identified were examined for any additional studies appropriate for the review. Fesoterodine, a competitive muscarinic receptor antagonist, is converted to its active metabolite, 5-hydroxymethyltolterodine, by nonspecific esterases, bypassing the cytochrome P450 system. Two randomized controlled Phase 3 trials examined the safety and efficacy of fesoterodine in the treatment of overactive bladder. Fesoterodine was found to produce significant improvements in the treatment of overactive bladder symptoms compared with placebo. Post hoc analysis of these trials demonstrated significant improvements in health-related quality of life in patients with overactive bladder. Only one study included tolterodine, and direct comparisons between fesoterodine and tolterodine were not conducted. The most common treatment-emergent adverse effects associated with fesoterodine included dry mouth, constipation, urinary tract infection, and headache. Fesoterodine appears to be effective and generally safe for the treatment of overactive bladder. The efficacy and safety of fesoterodine in overactive bladder treatment seem to be at least similar to that of tolterodine. Although additional comparative trials are needed, based on available data, it does not appear that fesoterodine provides a substantial advantage over extended-release tolterodine in either efficacy or safety.

  8. Systematization of a set of closure techniques.

    Approximations in population dynamics are gaining popularity since stochastic models in large populations are time consuming even on a computer. Stochastic modeling causes an infinite set of ordinary differential equations for the moments. Closure models are useful since they recast this infinite set into a finite set of ordinary differential equations. This paper systematizes a set of closure approximations. We develop a system, which we call a power p closure of n moments, where 0≤p≤n. Keeling's (2000a,b) approximation with third order moments is shown to be an instantiation of this system which we call a power 3 closure of 3 moments. We present an epidemiological example and evaluate the system for third and fourth moments compared with Monte Carlo simulations.

    A novel method is proposed to construct collisionless fluid closures accounting for some kinetic properties. The idea consists in optimizing the agreement between the fluid and kinetic quasi-linear entropy production rates, so as to constrain the closure coefficients. This procedure is applied to the slab branch of the ion temperature gradient driven instability. Focusing on the kinetic regime characterized by slow waves, the closure proposed by Hammett and Perkins (Hammett and Perkins 1990 Phys. Rev. Lett. 64 3019) naturally emerges from the systematic identification of the kinetic and fluid entropy production rates. This closure is revealed to be extremely powerful well beyond the kinetic regime. Besides, it reconciles the fluid and kinetic linear stability diagrams in the two-dimensional space of the density and temperature gradient lengths. Such a method is systematic and generic. As such, it is applicable to other models and classes of instabilities.

    Aims: To compare simple analytical closure models of turbulent Boussinesq convection for stellar applications with direct three-dimensional simulations both in homogeneous and inhomogeneous (bounded) setups. Methods: We use simple analytical closure models to compute the fluxes of angular momentum and heat as a function of rotation rate measured by the Taylor number. We also investigate cases with varying angles between the angular velocity and gravity vectors, corresponding to locating the computational domain at different latitudes ranging from the pole to the equator of the star. We perform three-dimensional numerical simulations in the same parameter regimes for comparison. The free parameters appearing in the closure models are calibrated by two fit methods using simulation data. Unique determination of the closure parameters is possible only in the non-rotating case and when the system is placed at the pole. In the other cases the fit procedures yield somewhat differing results. The quality of the closu...

    The intent of the WIPP, being constructed in the bedded geologic salt deposits of Southeastern New Mexico, is to provide the technological basis for the safe disposal of radioactive Transuranic (TRU) wastes generated by the defense programs of the United States. In determining this technological basis, advanced reliability and structural analysis techniques are used to determine the probability of time-to-closure of a hypothetical underground shaft located in an argillaceous salt formation and filled with compacted crushed salt. Before being filled with crushed salt for sealing, the shaft provides access to an underground facility. Reliable closure of the shaft depends upon the sealing of the shaft through creep closure and recompaction of crushed backfill. Appropriate methods are demonstrated to calculate cumulative distribution functions of the closure based on laboratory determined random variable uncertainty in salt creep properties.

  13. Cyanoacrylate for Intraoral Wound Closure: A Possibility?

    2015-01-01

    Full Text Available Wound closure is a part of any surgical procedure and the objective of laceration repair or incision closure is to approximate the edges of a wound so that natural healing process may occur. Over the years new biomaterials have been discovered as an alternate to conventional suture materials. Cyanoacrylate bioadhesives are one among them. They carry the advantages of rapid application, patient comfort, resistance to infection, hemostatic properties, and no suture removal anxiety. Hence this study was undertaken to study the effect of long chain cyanoacrylate as an adhesive for intraoral wound closure and also to explore its hemostatic and antibacterial effects. Isoamyl-2-cyanoacrylate (AMCRYLATE was used as the adhesive in the study. In conclusion isoamyl cyanoacrylate can be used for intraoral wound closure, as an alternative to sutures for gluing the mucoperiosteum to bone, for example, after impaction removal, periapical surgeries, and cleft repair. Its hemostatic and antibacterial activity has to be further evaluated.

    The comparison of the clinical results and costs of the two methods of closure of patient ductus arteriosus was undertaken in two comparable groups of 40 patients treated in the same period in the same hospital. After transcatheter closure there was a 9% residual shunt rate at 3 years, the 2 patients with a residual continuous murmur being operated secondarily. The only complication was severe haemolysis which regressed after transcatheter ablation of the prosthesis. After surgical closure, there were no residual shunt. Some postoperative complications were observed in 20% of cases, usually benign (ventilatory problems, dysphonia or urinary infection), but occasionally more serious (peroperative lesion of the pulmonary artery). Morbidity, inherent to the technique of closure, was very different and much less in catheter closure. The average cost (daily cost x average length of hospital stay) was much less with transcatheter closure 38,558 francs versus 11,240 francs. On the other hand, the direct cost of transcatheter closure was greater than that of surgery: 32,798 francs versus 20,903 francs, the difference being related to the actual price of the prosthesis. The authors conclude that the 3 year results of transcatheter closure of patent ductus arterious make this technique a reasonable therapeutic alternative to surgery. From the safety point of view, the two techniques are comparable bu patient confort is greater with transcatheter closure for an increase in cost of the initial procedure which should decrease in relation to the types and prices of the prosthesis used.

    Mediastinitis affects approximately 1% of children undergoing median sternotomy. Conventional therapy involves debridement followed by open wound care with delayed closure, days to weeks of closed suction or antimicrobial irrigation, and vacuum-assisted closure or muscle flap closure. We hypothesized that primary closure without prolonged suction or irrigation is an effective, less traumatic treatment for mediastinitis in children. From January 1986 to July 2002, 6705 procedures involving median sternotomy were performed at the C. S. Mott Children's Hospital, resulting in 57 cases of mediastinitis (0.85%). Cases were divided into 2 groups, with 42 cases treated with primary closure and 15 cases treated with delayed or muscle flap closure. The 42 cases of primary closure comprised the primary study group of this institutional review board-approved, retrospective analysis. Patient demographics, surgical variables, mediastinitis-related parameters, and outcomes were evaluated. One patient had recurrent mediastinitis for an overall infection eradication rate of 97% (40/41). Three patients (7%) required re-exploration for suspected ongoing infection. Of these re-explorations, 1 patient had evidence of continued mediastinitis. The remaining 2 patients with sepsis of unclear cause had no clinical or culture evidence of recurrent infection. One of these patients ultimately died of sepsis without active mediastinitis for a hospital survival of 97% (41/42). No significant differences could be detected between the treatment successes and failures in this small cohort of patients. Simple primary closure is an effective means to treat selected cases of postoperative mediastinitis in children. The results compare favorably with other more lengthy or debilitating treatments.

    Until the 1970s, bladder exstrophy was a frequently fatal birth defect that, at the very least, conferred a shortened life span with devastating consequences for afflicted patients. Beginning with the modern era of surgical management, survival has become routine, and now the focus is on optimizing a near-normal return to function and cosmesis while limiting the frequency and morbidity of reconstructive procedures. Here we discuss the most frequently used strategies, their principles, and most recent outcomes for the management of exstrophy worldwide. Advantages and disadvantages of each approach are discussed in broad terms with the understanding that one universally accepted technique for managing bladder exstrophy has yet to be developed.

    In order to detect the expression of Oct4 in bladder cancer tissue and cell line BIU-87, immunohistochemistry was used in 49 bladder cancer biopsy samples and immunofluorescence and reverse transcription-PCR were performed on bladder cancer cell line BIU-87. Forty of 49 bladdercancer samples showed the expression of Oct4 in about 0.6% cancer cells. The positive rate and den-sity of Oct4 expression had no obvious relationship with the grade, recurrence or metastasis of blad-der cancer (P0.05). A few Oct4 positive cells were found in bladder cancer cell line BlU-87, which was also confirmed by RT-PCR. This study indicated the existence of few Oct4 positive cells in bladder cancer, which may be the bladder cancer stem cells. This study may provide the foundation for isolation and identification of bladder cancer stem cells.

    Full Text Available Diagnostics of urinary bladder tuberculosis bases on pathological verification. Standard histological staining (hematoxylin–eosin reveals glaucomatous inflammation, but cannot estimate its etiology.Aim of our study was to evaluate the role of complex immunohistochemical method in diagnostic of tuberculosis infection in bladder. Our study included 21 histological specimen of the resected bladder in case of nephrotuberculosis. Standard histological examination revealed specific changes in bladder tissue only in 2 cases, while immunohistochemical method with antibodies to Mycobacterium tuberculosis (MBT demonstrated positive reaction at 5 patients. Investigation of lower urinary tract function in late postoperative period showed that patients with positive anti-MBT reaction had clinically significant chronic urinary retention, as well as their degree of urinary disorders assessed using a questionnaire IPSS-Qol was higher. Thus, the use of IHC method in combination with standard histological examination improves diagnostics of urinary bladder tuberculosis, and it may serve the predictor of long-term results of surgical treatment of microcystis.

    An underground tank assembly is described for storing motor fuels, such as gasoline or diesel fuel, comprising: a collapsible primary tank comprising a flexible bladder for containing a motor fuel, the primary tank being moveable from a collapsed generally empty position to an inflated generally full position; a substantially rigid secondary tank substantially surrounding and enclosing the primary tank for secondary containment of an leakage of motor fuel from the primary tank, the secondary tank having a top, a bottom, and end walls extending between and connecting the top and bottom; the bladder having a bottom portion positioned adjacent the bottom of the secondary tank; and conduit means extending through the top of the rigid secondary tank to a position in proximity to the bottom portion of the flexible bladder. The conduit means includes an inlet conduit with an inlet upright portion for filing the flexible bladder with motor fuel and an outlet conduit with an outlet upright portion for withdrawing the motor fuel from the flexible bladder. The outlet upright portion of the outlet conduit is positioned within the interior of and is substantially concentrically and coaxially surrounded by the inlet upright portion of the inlet conduit. The outlet conduit and the inlet conduit both are positioned in proximity to one of the end walls of the rigid secondary tank.

    Full Text Available Background: Ultrasound has been shown to be a sensitive method for evaluating patients with chronic obstruction, bladder outlet obstruction, urinary tract infection, renal failure, renal and bladder neoplasm and renal transplants. It is now recommended as the method of choice for preliminary assessment and follow-up of several of these disorders. The objective of the study was to evaluate the specificity and sensitivity of ultrasonographic features of neoplastic lesions of urinary bladder. Methods: Clinical impression about the suspected abnormality was obtained from the case papers or from referring by clinical colleagues. Data was recorded under headings like clinical history, clinical examinations, investigations like urine analysis, serum creatinine and blood urea, X-ray of chest and Kidney Urinary Bladder, pelvic and abdominal Ultrasonography, and if require CT scan and guided biopsy. Results: out of total 35 cases 29 were Transitional Cell Carcinoma, 4 were Squamous Cell Carcinoma, One leiomyoma and one was secondary from bronchogenic carcinoma. Most of tumours were irregular in shape in both TCC and SCC patients. Most of tumour showed heterogeneous echo-texture in ultrasonography. While all SCC showed heterogeneous with calcification echo-texture. Most of the cases had residual urine volume was less than 100 cc. Conclusions: The primary advantage of ultrasound over the conventional study was found to be its ability to detect focal or diffuse bladder wall abnormalities in patients who presented with commonest complaint of painless hematuria.

    Several studies have reported lower neck muscle strength in patients with chronic neck pain compared to healthy controls. The aim of the present study was to evaluate the association between the severity of neck pain and disability with neck strength and range of movement in women suffering from chronic neck pain. One hundred and seventy-nine female office workers with chronic neck pain were selected to the study. The outcome was assessed by the self-rating questionnaires on neck pain (visual analogue scale, Vernon's disability index, Neck pain and disability index) and by measures of the passive range of movement (ROM) and maximal isometric neck muscle strength. No statistically significant correlation was found between perceived neck pain and the disability indices and the maximal isometric neck strength and ROM measures. However, the pain values reported during the strength tests were inversely correlated with the results of strength tests (r=-0.24 to -0.46), showing that pain was associated with decreased force production. About two-thirds of the patients felt pain during test efforts. Pain may prevent full effort during strength tests and hence the production of maximal force. Thus in patients with chronic neck pain the results do not always describe true maximal strength, but rather the patients' ability to bear strain, which may be considerably influenced by their painful condition. The results of the present study suggest that rehabilitation in cases of chronic neck pain should aim at raising tolerance to mechanical strain.

    To review the evolution of urinary diversion, bladder augmentation and bladder replacement in the paediatric population over the past century and to outline the possible direction of future management. Original and review articles obtained from a PubMed search of English language publications dating from 1970 to 2001. The search terms were "bladder augmentation", "bladder substitution", "bladder autoaugmentation", "ureterocystoplasty" and "bladder engineering". The age group was "all child 0-18". Articles selected were those with relevance to the scope of the topic. The articles were analyzed with the primary focus being the problems encountered with various forms of urinary diversion, bladder augmentation and bladder replacement, and the subsequent evolution of materials and techniques. Bladder tissue may need to be replaced in the paediatric population because of congenital malformation, disease or trauma. The unique structure and function of urothelium and bladder muscle make this a challenging task. Management has evolved from a mindset of attempting to divert urine from the bladder completely to that of trying to preserve what is salvageable of the organ. Historically and contemporarily, the gastrointestinal tract has provided the raw material for urinary diversion, bladder augmentation and bladder substitution. Experience, however, has highlighted the potential complications inherent in the use of the bowel in the urinary tract including mucus production, stone disease, metabolic abnormalities, growth retardation, spontaneous perforation and malignancy. However, despite these drawbacks, the bowel is the gold standard in terms of functional utility and longevity. In efforts to develop alternatives, research has focused on the use of both natural and synthetic materials. With these materials, a whole new list of potential problems has been characterized. Tissue engineering may hold promise in resolving the issues of bladder replacement or repair by providing

    Daniel L Coutu

    Full Text Available Bladder replacement or augmentation is required in congenital malformations or following trauma or cancer. The current surgical solution involves enterocystoplasty but is associated with high complication rates. Strategies for bladder tissue engineering are thus actively sought to address this unmet clinical need. Because of the poor efficacy of synthetic polymers, the use of bladder acellular matrix (BAM has been proposed. Indeed when cellular components are removed from xenogenic or allogeneic bladders, the extracellular matrix scaffold thus obtained can be used alone or in combination with stem cells. In this study, we propose the use of BAM seeded with marrow-derived mesenchymal stem cells (MSCs for bladder tissue engineering. We optimized a protocol for decellularization of bladder tissue from different species including rat, rabbit and swine. We demonstrate the use of non-ionic detergents followed by nuclease digestion results in efficient decellularization while preserving the extracellular matrix. When MSCs were seeded on acellular matrix scaffold, they remained viable and proliferative while adopting a cellular phenotype consistent with their microenvironment. Upon transplantation in rats after partial cystectomy, MSC-seeded BAM proved superior to unseeded BAM with animals recovering nearly 100% normal bladder capacity for up to six months. Histological analyses also demonstrated increased muscle regeneration.

  10. Involvement of STAT3 in Bladder Smooth Muscle Hypertrophy Following Bladder Outlet Obstruction

    2006-12-01

    Full Text Available We examined the involvement of the signal transducer and activator of transcription 3 (STAT3 in bladder outlet obstruction (BOO-induced bladder smooth muscle hypertrophy using a rat in vivo and in vitro study. BOO induced increases in bladder weight and bladder smooth muscle thickness 1 week after the operation. By using antibody microarrays, 64 of 389 proteins blotted on the array met our selection criteria of an INR value between > or = 2.0 and < or = 0.5. This result revealed up-regulation of transcription factors, cell cycle regulatory proteins, apoptosis-associated proteins and so on. On the other hand, down-regulation (INR value < or = 0.5 of proteins was not found. In a profiling study, we found an increase in the expression of STAT3. A significant increase in nuclear phosphorylated STAT3 expression was confirmed in bladder smooth muscle tissue by immunohistochemistry and Western blot analysis. Cyclical stretch-relaxation (1 Hz at 120% elongation significantly increased the expression of STAT3 and of alpha-smooth muscle actin in primary cultured bladder smooth muscle cells. Furthermore, the blockade of STAT3 expression by the transfection of STAT3 small interfering RNA (siRNA significantly prevented the stretch-induced increase in alpha-smooth muscle actin expression. These results suggest that STAT3 has an important role in the induction of bladder smooth muscle hypertrophy.

    1995-04-01

    Almost a decade ago the Office of Nuclear Regulatory Research (RES) developed and implemented a comprehensive research program (NUREG-1144) widely known as NPAR or Nuclear Plant Aging Research. The NPAR program is a structured research program specifically oriented to understanding significant age-related degradation mechanisms and their long term effects on properties and performance of important components and systems and ways to mitigate detrimental effects of aging. It provided a road map and a phased approach to research that is applicable to any structure, system, or component of interest. This hardware-oriented engineering research program led the industry worldwide and communicated a need to understand and manage age-related degradation effects in selected but important structures and components. At the conclusion (1995) of the NPAR program, 22 electrical and mechanical components, 13 safety-related systems, and 10 special topics will have been studied and results summarized in 160 technical reports. This reference library of information listed and summarized in NUREG-1377, Rev. No. 4 provides a foundation upon which individual programs can be built for the specific needs of a utility, a regulator, or equipment manufacturers. During the life of the NPAR program, it has provided technical bases and support for license renewal, codes and standards, resolution of generic safety issues, information notices, regulatory guides and the standard Review Plan, as well as the Office of Nuclear Reactor Regulation and The NRC Regions. All ongoing NPAR activities will either be completed or terminated by the end of 1995. No new initiative will be undertaken. This paper summarizes NPAR products and accomplishments, application of the research results, and its status and closure.

    1998-06-01

    This report describes the status of Environmental Management`s (EM`s) cleanup program and a direction forward to complete achievement of the 2006 vision. Achieving the 2006 vision results in significant benefits related to accomplishing EM program objectives. As DOE sites accelerate cleanup activities, risks to public health, the environment, and worker safety and health are all reduced. Finding more efficient ways to conduct work can result in making compliance with applicable environmental requirements easier to achieve. Finally, as cleanup activities at sites are completed, the EM program can focus attention and resources on the small number of sites with more complex cleanup challenges. Chapter 1 describes the process by which this report has been developed and what it hopes to accomplish, its relationship to the EM decision-making process, and a general background of the EM mission and program. Chapter 2 describes how the site-by-site projections were constructed, and summarizes, for each of DOE`s 11 Operations/Field Offices, the projected costs and schedules for completing the cleanup mission. Chapter 3 presents summaries of the detailed cleanup projections from three of the 11 Operations/Field Offices: Rocky Flats (Colorado), Richland (Washington), and Savannah River (South Carolina). The remaining eight Operations/Field Office summaries are in Appendix E. Chapter 4 reviews the cost drivers, budgetary constraints, and performance enhancements underlying the detailed analysis of the 353 projects that comprise EM`s accelerated cleanup and closure effort. Chapter 5 describes a management system to support the EM program. Chapter 6 provides responses to the general comments received on the February draft of this document.

    Surgical repair of postlaryngectomy pharyngocutaneous fistula (PCF) can be challenging. Although several studies describe separate reconstruction methods, only few address the variability in defect characteristics and hence flap selection. The current clinical study presents a retrospective review of 19 patients who underwent surgical repair of persistent PCFs, over a 4-year period in a tertiary referral institute by a single primary surgeon. All but one patient were men with a mean age of 61 +/- 10 years. Nine patients had previous unsuccessful attempts for surgical closure. Previous neck irradiation was the most common comorbid condition encountered (52.6%), followed by low hemoglobin level (47.4%), hepatic disease (36.8%) and diabetes mellitus (31.6%). According to defect characteristics, six patients received a local cervical skin procedure, ten patients had reconstructions using the pectoralis major musculocutaneous flap and three patients required a radial forearm free flap repair. All PCFs were eventually successfully closed with no major complications. Patients were followed-up for an average of 19.7 months (range, 5-38 months). Acceptable oral swallowing results were achieved in all but one patient. In conclusion, successful results are achievable in difficult persistent PCF cases with a defect based reconstruction approach kept in mind.

    To describe a novel transurethral front-firing Greenlight bladder autoaugmentation for the treatment of bladder contracture and report initial clinical outcomes. Between April 2014 and August 2015, five patients diagnosed with contracted bladder were all refractory to conservative treatment and received novel transurethral autoaugmentation. CT scan and urodynamics examination were conducted before operation for disease assessment. Mucosal and muscular layers of bladder wall in fundus were incised vertically and horizontally with front-firing Greenlight laser to enlarge bladder capacity in the operation. Imaging examination and periodical urodynamics study were performed to evaluate the clinical outcomes of the procedure in postoperative follow-up. Transurethral front-firing Greenlight bladder autoaugmentation was performed successfully on all the patients. The mean operative time was 59 min (range 52-65 min) with no significant blood loss. Urodynamic parameters of these patients after operation improved significantly compared with those before operation. Average maximum cystometric capacity (Vmax) increased from 91.2 to 333 ml (p < 0.01), average maximum flow rate (Qmax) ascended from 12.6 to 18.62 ml/min (p < 0.01), and average flow rate (Q(ave)) also increased from 5.74 to 13.18 ml/min (p < 0.01). At the last follow-up, all the patients could void spontaneously with good bladder emptying and their symptoms improved significantly. Our novel transurethral front-firing Greenlight bladder autoaugmentation is a safe and effective treatment for contracted bladders. Future studies with larger sample size and long-term follow-up are needed to confirm our findings.

    Full Text Available Platinum-based chemotherapy is commonly used for the treatment of locally advanced and metastatic bladder cancer. However, there are currently no methods to predict chemotherapy response in this disease setting. A better understanding of the biology of bladder cancer has led to developments of molecular biomarkers that may help guide clinical decision making. These biomarkers, while promising, have not yet been validated in prospective trials and are not ready for clinical applications. As alkylating agents, platinum drugs kill cancer cells mainly through induction of DNA damage. A microdosing approach is currently being tested to determine if chemoresistance can be identified by measuring platinum-induced DNA damage using highly sensitive accelerator mass spectrometry technology. The hope is that these emerging strategies will help pave the road towards personalized therapy in advanced bladder cancer.

    Full Text Available The stomach is the preferred augmentation option for a contracted bladder in a patient with renal failure. A 49-year-old female presented with right solitary functioning kidney with tuberculous lower ureteric stricture and contracted bladder. Her creatinine was 2.8 mg%. By laparoscopic approach, right gastroepiploic artery based gastric flap was isolated using staplers and used for augmentation and ureteric replacement. At 6-month follow-up, her creatinine was 1.9 mg%, and bladder capacity was 250 ml. She had mild hematuria, which settled with proton pump inhibitors. Laparoscopic gastrocystoplasty is feasible and effective augmentation option in those with renal failure, giving the benefits of minimally invasive approach.

A 35-year-old pre-menopausal female presented with 2 FNx01 2 cm right upper outer quadrant breast lump. Post-mastectomy, histology confirmed it to be metastatic adenocarcinoma positive for both Cytokeratin (CK 7 and CK20. Past history as told by the patient revealed that 2 years back, cholecystectomy was performed for gall stones, of which no histology reports were present; she had a port site scar recurrence which showed it to be adenocarcinoma. Adjuvant chemotherapy and radiotherapy was advised which the patient did not complete. This is probably the first case reported of isolated breast metastasis from gall bladder carcinoma, diagnosed retrospectively. It also highlights the importance of adjuvant treatment in gall bladder malignancy.

    Bladder cancer is an urologic common tumor after prostate carcinoma. Radical treatment of localized invasive tumor is based on cystectomy. Surgical mutilation could be important when Bricker's urinary derivation is performed. Moreover, delayed metastasis frequently appeared in spite of radical surgery. Thus, chemoradiotherapy is a valid alternative treatment to cystectomy for selected patients. Cisplatin or derivatives are usually concurrently administered to radiation therapy up to 60 - 65 Gy. Patients undergo control cystoscopy at mid-time of treatment in order to select responders from non responders. For majority of cases, the empty bladder should be entirely treated with added margins (about 20 mm) to build the PTV. Control assessment could be improved by echography, cone beam imaging as well as bladder fiduciaries implantation before treatment. From a case report, this review summarizes the technical aspects of radiation therapy (GTV, CTV and PTV, organs at risk, planning) and main acute and late related toxicities. (authors)

    Over the past several decades, few new systemic agents have been incorporated into the treatment paradigm for bladder cancer. Platinum-based therapy remains the cornerstone of treatment in the perioperative and metastatic settings. Despite level one evidence, use of cisplatin-based therapy in the neoadjuvant setting has been dismal. Second-line therapy for metastatic disease has only modest activity with no survival benefit. However, the elucidation and investigation of novel molecular targets, new therapeutics, and associated biomarkers with strong biologic rationale are actively changing the landscape in bladder cancer. Although the field is moving rapidly, no new drug approvals are currently pending and a need remains to continue to educate the medical oncology and urology communities on the optimal use of currently available treatments. This article outlines the evidence, including that from prospective studies and meta-analyses, providing the basis for the current recommendations from NCCN, and details previous and ongoing studies of targeted therapy for bladder cancer.

    Bladder carcinoma is the most common tumor among the low urinary tract, accounting for 90% of cancer cases. Conventional cystoscopy represents the gold standard for diagnosis and local management of bladder carcinoma. As the prevalence of transitional cell carcinoma is four-fold greater in men than in women, the endoscopic procedure presents objective difficulties related to the length and bending of male urethra. The most important problems are represented by intense discomfort for the patient and bleeding; furthermore, the high cost, invasivity, and local complications such as infections and mechanical lesions are well-known drawbacks. Additionally, conventional cystoscopy does not provide information about extravescical extensions of the tumor. CT cystography, combined with virtual cystoscopy, is mandatory for TNM staging of the tumor and also is useful when conventional cystoscopy is inconclusive or cannot be performed. We presents the CT cystography findings with virtual endoscopy correlation and bladder carcinoma appearance.

    2016-02-01

    Alteration in neural control from suprapontine areas to the nerves innervating the bladder can lead to bladder dysfunction and the development of a neurogenic bladder (NGB). Patients with NGB often suffer from urinary incontinence, which can lead to adverse events such as urinary tract infections and decubiti, in addition to creating a large care burden for family members or healthcare providers and significantly impairing patient quality of life. The common failure of anticholinergic medications has spurned the development of second-line treatments, including the use of botulinum toxin. OnabotulinumtoxinA (onaBoNT-A; BOTOX, Allergan, Inc.) was approved by the U.S. Food and Drug Administration (FDA) in 2011 to treat neurogenic detrusor overactivity in patients with urinary incontinence resulting from a NGB. In this review the authors summarize pertinent results from key trials leading to FDA approval of onaBoNT-A as well as more recent long-term data.

    Ringler, Todd D [Los Alamos National Laboratory

    2009-01-01

    The Gent-McWilliams (GM) parameterization is extended to include a direct influence in the momentum equation. The extension is carried out in two stages; an analysis of the inviscid system is followed by an analysis of the viscous system. In the inviscid analysis the momentum equation is modified such that potential vorticity is conserved along particle trajectories following a transport velocity that includes the Bolus velocity in a manner exactly analogous to the continuity and tracer equations. In addition (and in contrast to traditional GM closures), the new formulation of the inviscid momentum equation results in a conservative exchange between potential and kinetic forms of energy. The inviscid form of the eddy closure conserves total energy to within an error proportional to the time derivative of the Bolus velocity. The hypothesis that the viscous term in the momentum equation should give rise to potential vorticity being diffused along isopycnals in a manner analogous to other tracers is examined in detail. While the form of the momentum closure that follows from a strict adherence to this hypothesis is not immediately interpretable within the constructs of traditional momentum closures, three approximations to this hypothesis results in a form of dissipation that is consistent with traditional Laplacian diffusion. The first two approximations are that relative vorticity, not potential vorticity, is diffused along isopyncals and that the flow is in approximate geostrophic balance. An additional approximation to the Jacobian term is required when the dissipation coefficient varies in space. More importantly, the critique of this hypothesis results in the conclusion that the viscosity parameter in the momentum equation should be identical to the tradition GM closure parameter {Kappa}. Overall, we deem the viscous form of the eddy closure for potential vorticity as a viable closure for use in ocean circulation models.

    Inflammatory pseudotumor of the urinary bladder is a rare benign lesion. Because it is difficult to differentiate from other tumors clinically and pathologically, histopathologic confirmation is needed, and to avoid unnecessary cystectomy, it should be included in the differential diagnosis. A 47-year-old male presented with hematuria and voiding difficulty. IVP revealed a triangular filling defect in the urinary bladder, and CT demonstrated the presence there of a strongly enhancing mass. We deseribe this case, in which inflammatory pseudotumor was diagnosed, and review literature.

The involve-ment of the urinary tract is rare and primary actinomyco-sis of urinary bladder is still rarer. The disease is usually diagnosed by demonstration of the discharged sulphur granules. In our case this was not the usual presentation and the patient was first diagnosed as having appendicu-lar mass and then bladder malignancy. The excised mass demonstrated features suggestive of actinomycosis.

    Urinary tract infections (UTIs) are frequent, recurrent, and lifelong for patients with neurogenic bladder and present challenges in diagnosis and treatment. Patients often present without classic symptoms of UTI but with abdominal or back pain, increased spasticity, and urinary incontinence. Failure to recognize and treat infections can quickly lead to life-threatening autonomic dysreflexia or sepsis, whereas overtreatment contributes to antibiotic resistance, thus limiting future treatment options. Multiple prevention methods are used but evidence-based practices are few. Prevention and treatment of symptomatic UTI requires a multimodal approach that focuses on bladder management as well as accurate diagnosis and appropriate antibiotic treatment.

    Full Text Available Ascariasis is a common disease in many developing countries and is a common cause of biliary and pancreatic diseases in endemic areas. Numerous studies have been published on biliary tract ascariasis. All these have documented ultrasonography as the primary imaging modality for biliary tract ascariasis. Magnetic Resonance Cholangiopancreatography (MRCP has been the latest entrant for the study of bilary tract. MRCP findings of biliary tract ascariasis have been scarcely documented. MRCP is a unique non-invasive investigation for demonstrating ascariasis in Gall bladder and bilary tract clearly. We present MR appearances of Gall bladder and biliary tract in a proven case of biliary ascariasis.

    Encrusted cystitis is a subtype of chronic cystitis characterized by multiple calcifications in the form of plaques located in the interstitium of the urinary bladder mucosa and frequently associated with mucosal ulcers. It is a very rare disease of controversial etiology. Our transmission electron microscopy of the calcified plaques of encrusted cystitis has revealed that the smallest formed particles (elementary units) of these calcifications are electron-dense shells surrounding an electron lucent core, diagnostic of calcifying nanoparticles (previously called nanobacteria). We pioneer the notion that calcifying nanoparticles are the causative agents of encrusted urinary bladder cystitis.

    2012-01-01

    Full Text Available Introduction. Optimal therapy for patients with metastatic neck disease remains controversial. Neck dissection following radiotherapy has traditionally been used to improve locoregional control. Methods. A retrospective review of 28 patients with node-positive head and neck malignancy treated with planned neck dissection following radiotherapy between January 2002 and December 2005 was performed to assess treatment outcomes. Results. Median interval to neck dissection was 9.6 weeks with a median number of 21 + 9 lymph nodes per specimen. Ten of 31 (32% neck dissection specimens demonstrated evidence of residual carcinoma. Overall survival at two years was 85%; five-year overall survival was 65%. Concurrent chemotherapy did not impact the presence of residual neck disease. Conclusion. Based on the frequency of residual malignancy in the neck of patients treated with primary radiotherapy, a planned, postradiotherapy neck dissection should be strongly advocated for all patients with advanced-stage neck disease.

  6. PHASE CLOSURE NULLING: THEORY AND PRACTICE

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available We provide a complete theory of the phase closure of a binary system in which a small, feeble, and unresolved companion acts as a perturbing parameter on the spatial frequency spectrum of a dominant, bright, resolved source. We demonstrate that the in uence of the companion can be measured with precision by measuring the phase closure of the system near the nulls of the primary visibility function. In these regions of phase closure nulling, frequency intervals always exist where the phase closure signature of the companion is larger than any systematic error and can thus be measured. We show that this technique allows retrieval of many astrophysically relevant properties of faint and close companions such as ux, position, and in favorable cases, spectrum. As a proof of concept, using the AMBER/VLTI instrument with 3 auxiliary telescopes of 1.8 m and only 15 minutes of on-sky integration, we detected the ve magnitudes fainter companion of HD 59717 at only 3.5 stellar radii distance from the primary. This is one of the highest contrast detected by interferometry between a companion and its parent star. We conclude by a rapid study of the potentialities of phase closure nulling observations with current interferometers and explore the requirements for a new type of dedicated instrument.

  7. Space Station evolution study oxygen loop closure

    1993-01-01

    In the current Space Station Freedom (SSF) Permanently Manned Configuration (PMC), physical scars for closing the oxygen loop by the addition of oxygen generation and carbon dioxide reduction hardware are not included. During station restructuring, the capability for oxygen loop closure was deferred to the B-modules. As such, the ability to close the oxygen loop in the U.S. Laboratory module (LAB A) and the Habitation A module (HAB A) is contingent on the presence of the B modules. To base oxygen loop closure of SSF on the funding of the B-modules may not be desirable. Therefore, this study was requested to evaluate the necessary hooks and scars in the A-modules to facilitate closure of the oxygen loop at or subsequent to PMC. The study defines the scars for oxygen loop closure with impacts to cost, weight and volume and assesses the effects of byproduct venting. In addition, the recommended scenarios for closure with regard to topology and packaging are presented.

    2015-09-01

    Full Text Available Instillation therapy with attenuated tuberculosis bacteria (BCG can significantly reduce rates of recurrence of non-muscle invasive bladder cancer. Local and systemic side effects such as dysuria, irritative voiding symptoms or partial bladder contracture and systemic inflammation were reported. A 75 year-old male patient with recurrent non muscle invasive bladder cancer developed necrosis of the entire bladder urothelium more than six years after BCG instillation immunotherapy. The resulting irritative voiding symptoms and low bladder capacity required radical cystectomy. BCG instillation can cause severe side effects, which develop gradually and eventually need radical surgical therapy such as cystectomy without tumor recurrence.

    Acevedo, C G; Tamayo, L; Contreras, E

    1986-01-01

    Acute morphine increased the responses to acetylcholine of the isolated mouse urinary bladder. A chronic morphine treatment did not change the responses of the urinary bladder to acetylcholine or ATP. The acute administration of morphine did not modify the contractile response to ATP in the urinary bladders from untreated or chronically morphine treated mice. Methadone and ketocyclazocine decreased the responses to the electrical stimulation of the urinary bladder. These depressant effects were not modified by naloxone. The results suggest the nonexistence of opiate receptors in the mouse urinary bladder and the lack of direct effects of morphine on the neuroeffector junction.

  11. HpD Photobiology And Photodynamic Therapy Of Bladder Carcinoma

    Science.gov (United States)

    Lin, Chi-Wei

    1988-02-01

    Bladder carcinoma is considered one of the most favorable targets for the application of photodynamic therapy (PDT) due to the accessibility of the bladder for light delivery. Examination of the bladder and surgical procedures are routinely performed by the insertion of an optical instrument called cystoscope through the urethra. Thus, the treatment of bladder cancer by PDT can be conducted through the cystoscope with minimal invasion. However, to achieve optimal results from this treatment, one must consider both the structure of the bladder and the nature of the carcinoma.

    The goal of the present study was to determine if supraspinal pathways are necessary for inhibition of bladder reflex activity induced by activation of somatic afferents in the pudendal or tibial nerve. Cats anesthetized with α-chloralose were studied after acute spinal cord transection at the thoracic T9/T10 level. Dilute (0.25%) acetic acid was used to irritate the bladder, activate nociceptive afferent C-fibers, and trigger spinal reflex bladder contractions (amplitude: 19.3 ± 2.9 cmH2O). Hexamethonium (a ganglionic blocker, intravenously) significantly (P irritation. Understanding the sites of action for PNS or TNS inhibition is important for the clinical application of pudendal or tibial neuromodulation to treat bladder dysfunctions.

    To assess the effectiveness and safety of the treatment with oral anticholinergic agents (Oxybutin clorure) in patients under 1 year old, and who aree carriers of high risk bladder secondary to neurological illness as well as no neurological one. Since 1989, we have indicated treatment with anticholinergic agents to 16 patients: 9 patients had neurogenic bladder secondary to: myelomeningocele (n=7) and sacrocoxigeal teratoma (n=2). Others 7 patients had non neurogenic bladder secondary to: posterior urethral valvulas (n=1), valvula-like syndrome (n=4), post-surgery of neonatal giant bladder diverticulum (n=1) and Prune-Belly syndrome (n=1). The urodinamic study was performed during the first six months of life, being "high risk bladder" defined according to the parameters of compliance vesical and pressure of leak at point (PER). Five of the patients showed neonatal cronic renal failure (CRF), who were treated by cutaneus temporary derivation. All patients at treatment with anticholinergic agents at a 0.2 mg/kg/day dose was established; other early adjunctive treatment prior to the closure of the urinary derivation in children with CRF(n=5); or as a part of the conservative treatment (n=3), alone or associate to intermittent bladder catheterization (IBC) (n=8). During the treatment with anticholinergic agents, the cardiac frequency was controlled by EKG registration in 6 patients, being the rest of the children clinicaly controled (skin colour, mouth dryness, cardiac frequency and intestinal function). In all the cases, the minimum duration of the treatment was one year, until the functional stabilization of the urinary tract. It is to underline the absence of secondary complications which would have caused the suspension or the reduction of the treatment at long term. Conventional studies of urologicals image and urodinamic studies, showed the stabilization of the urinary tract and also the preservation of kidney function and not only was demonstrated in those

    The possibility of bladder preservation by preoperative balloon occluded arterial infusion (BOAI) chemotherapy was studied in 111 patients with locally invasive bladder cancer. BOAI was performed by blocking the blood flow of the internal iliac artery and by performing intra-arterial infusion of adriamycin (50 mg/body) and cisplatin (100 mg/body). Before BOAI the clinical diagnosis was T2 in 36, T3a in 29, T3b in 27, T4 in 11 and after BOAI it was T0 in 1, T1 in 27, T2 in 25, T3a in 20, T3b in 20, and T4 in 10. Down staging was observed on diagnostic images in 46.6%. Thirty patients (27.0%) received transurethral resection of bladder tumor (TUR-Bt) and their bladder could be preserved. The 5-year cancer-specific survival rate was 100% in pT0 (n=9), 97.5% in pT1 (n=47), 79.9% in pT2 (n=21), 80.0% in pT3a (n=6), 39.9% in pT3b (n=18) and 51.9% in pT4 cases (n=9). For the bladder preservation, accurate staging diagnosis is required. Since 1992, endorectal magnetic resonance imaging (MRI) has been used in addition to imaging diagnosis for improving the accuracy of staging diagnosis. The accuracies of staging diagnosis with and without endorectal MRI were 62.5% and 44.0%, respectively. BOAI as a neoadjuvant chemotherapy has the possibility of bladder-preserving therapy in locally invasive bladder cancer. Also, the endorectal MRI can improve the accuracy of staging diagnosis, which is important for the bladder preservation. (author)

    Tsuda, K; Narumi, Y; Nakamura, H; Nonomura, I; Okuyama, A

    2000-11-01

    This article reviews the magnetic resonance (MR) staging of bladder cancer. The multiplanar and soft-tissue characterization capabilities of MR imaging make it a valuable diagnostic tool to image the urinary bladder. Recent advances of MR imaging such as fast imaging, pelvic phased array coil, and dynamic imaging improve the image quality and diagnostic accuracy for staging bladder cancer. Some patient-related factors are also important for optimal imaging of the urinary bladder, especially motion artifacts from the gastrointestinal tract and the degree of bladder distension. An anticholinergic agent should be used for suppressing the motion artifacts. Optimal bladder filling can be achieved by asking patients to void and drink water 1 hour before examinations. Scanning perpendicular to the bladder wall is necessary for optimal evaluation for staging bladder cancer. Oblique scanning is needed in cases when a tumor is not located on the dome, base, anterior wall, posterior wall, or lateral walls. The early phase image of dynamic imaging is most useful for staging tumors. Better contrast between tumor and bladder wall on dynamic images provides high staging accuracy, especially in differentiation between superficial tumors and tumors with muscle invasion. MR imaging is comparable to computed tomography (CT) in the evaluation of lymph nodes. Although MR imaging currently is not appropriate for screening for bladder cancer and detecting small tumors, it has been proved to be most useful in the staging of bladder cancer.

    Abstract Background: The purpose of this case presentation is to demonstrate how erosion of mesh into the bladder can initially present with the same symptoms as bladder malignancy. Case Presentation: A 62-year-old Hispanic male presented with 2 years of hematuria along with imaging concerning for a bladder tumor. The patient underwent cystoscopy with biopsy of a lesion at the anterior bladder. It was ultimately determined that a mesh plug from a prior hernia repair had migrated into the bladder. The mesh plug was excised using the Da Vinci Si robot, which allowed for efficient mobilization of the bladder and other anatomic structures, as well as rapid recovery. Conclusion: Our case demonstrates the need to consider mesh erosion as a cause of hematuria and, furthermore, shows how the robotic approach can help facilitate excision of migrated mesh into the bladder.

    Bladder conditions, including UTI, UI, and bladder cancer, are highly prevalent and affect a wide range of populations. There are a variety of modifiable behavioral and lifestyle factors that influence bladder health. Some factors, such as smoking and obesity, increase the risk or severity of bladder conditions, whereas other factors, such as pelvic floor muscle exercise, are protective. Although clinical practice may be assumed to be the most appropriate ground for education on behavioral and lifestyle factors that influence bladder health, it is also crucial to extend these messages into the general population through public health interventions to reach those who have not yet developed bladder conditions and to maximize the prevention impact of these behaviors. Appropriate changes in these factors have the potential for an enormous impact on bladder health if implemented on a population-based level.

    To determine the relationship between overactive bladder symptoms and urodynamic verification of overactive bladder. Between June 2011 and November 2011, 159 patients underwent urodynamics (UDS) at our urogynecology unit in the Ege University Hospital. Of these, 95 patients who complained of urgency, did not have any overt neurological diseases, bladder outlet obstruction and did not take any medication affecting the lower urinary tract function were evaluated. SPSS (ver. 15.0) was used to evaluate the data and the chi-square test and t test for independent samples were used for analysis. The mean age was found to be 54.5±12. Frequency was the most frequent symptom in women with overactive bladder (OAB) (82.1%), nocturia (57.8%) and (57.8%) urgency urinary incontinence followed in frequency. Detrusor over activity incidence was found to be 38.9%. There was no significant relationship between the presence of detrusor over activity (DOA) and OAB symptoms. Leak at urodynamics was found in 46.3% and there is no significant association with detrusor overactivity. Total bladder capacity was found to be significantly lower in women who had DOA (p=0.000). It appears that overactive bladder symptoms do not predict detrusor over activity. Urodynamic investigation is not mandatory in the initial management of women with only OAB symptoms.

    Full Text Available Appropriate management of patients with supraglottic laryngeal carcinoma and negative findings in the neck is still controversial. A prospective and retrospective study comprised 193 patients who were treated primary surgically between 1976 and 1993. They all had clinically and ultrasound negative findings on the neck (NO. Supraglottic carcinomas usually spread regionally. Metastases develop in the jugular group, between level II-IV. The incidence of metastases has been reported to vary from 12 to 62.5%. The size and localization of the primary tumor, its histological grade, genotype of the malignant cells, imunological and other elucidated factors can all affect the incidence of regional spread. AIM Aim of this study was to specify the incidence of occult cervical metastases; to analyze the distribution of occult metastases related to tumor localization; to specify the distribution of occult metastases related to local spread; to analyze the distribution of occult metastases according to localization in the neck. RESULTS All patients had primary surgery of primary tumor and bilateral jugular, selective neck dissection at the level II-IV with histological examination of removed lymphoid tissue. Out of 193 patients, metastatic deposits were detected in 35(18%. Occult metastases were found in patients with carcinoma of the epilarynx in 19% (14/72 of cases, and in 17% (21/121 patients with carcinoma of the supraglottis excluding the epilarynx. This difference in frequency is not statistically significant. The incidence of occult metastases in epilaryngeal tumors did not depend on the degree of local spread. Even relatively small tumors (T1 and T2 yielded occult metastases in 33% (5/15, and 24% (6/25 of patients, respectively. In patients with T1 tumors localized at the supraglottis, excluding the epilarinx, occult metastases were not found. In the supragiottis excluding the epilarynx increased local spread was associated an increase of occult

    Cardiac surgery is a very common operation nowadays all over the world. Median stemotomy is a routine procedure required for cardiac access during open heart surgery. The complications of this procedure after the cardiac surgery range from 0.7% to 1.5% of all cases, and bear a high mortality rate if they occur. Every individual surgeon must pay great attention on every detail during the sternal closure. This article shows the details as to conventional information and updated progress on median sternotomy closure. The update contents involve in biomechanics, number of wires twists, biomaterial and so on.According to our experience, we recommend four peristernal single/double steel wires for sternal closure as our optimal choice.

    Vlerick, Michael

    2014-12-01

    From the premise that our biology imposes cognitive constraints on our epistemic activities, a series of prominent authors--most notably Fodor, Chomsky and McGinn--have argued that we are cognitively closed to certain aspects and properties of the world. Cognitive constraints, they argue, entail cognitive closure. I argue that this is not the case. More precisely, I detect two unwarranted conflations at the core of arguments deriving closure from constraints. The first is a conflation of what I will refer to as 'representation' and 'object of representation'. The second confuses the cognitive scope of the assisted mind for that of the unassisted mind. Cognitive closure, I conclude, cannot be established from pointing out the (uncontroversial) existence of cognitive constraints.

    2003-06-01

    The Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) provides a coherent, technically defensible process for establishing that exposed surfaces satisfy site cleanup requirements. Unfortunately, many sites have complications that challenge a direct application of MARSSIM. Example complications include Record of Decision (ROD) requirements that are not MARSSIM-friendly, the potential for subsurface contamination, and incomplete characterization information. These types of complications are typically the rule, rather than the exception, for sites undergoing radiologically-driven remediation and closure. One such site is the Formerly Utilized Sites Remedial Action Program (FUSRAP) Linde site in Tonawanda, New York. Cleanup of the site is currently underway. The Linde site presented a number of challenges to designing and implementing a closure strategy consistent with MARSSIM. This paper discusses some of the closure issues confronted by the U.S. Army Corps of Engineers Buffalo District at the Linde site and describes how MARSSIM protocols were adapted to address these issues.

    Revision of all primitive tumours of the bladder diagnosed in our Service between July 1990 and July 1998. Among a total of 703 neoplasms of the bladder only 14 were non-transitional primitive tumours, accounting for just 1.98%. Eleven were malignant neoplasms with a diagnosis of epidermoid carcinoma in nine cases, one adenocarcinoma and one bladder adenocarcinoma. The other three were benign tumours: one haemangioma and two leiomyomas. From a clinical perspective, the predominant symptom was haematuria, followed by irritative symptoms. The two leiomyomas were accidental findings during a gynaecological examination (ultrasound) and a diagnostic examination for a nephritic colic (urography). The diagnostic means used and the extension studies were the same as used for transitional neoplasms. In general, treatment of benign neoplasms was partial cystectomy or transurethral resection while it was radical surgery for the malignant tumours when the existing criteria were an indication for that type of surgery (cystoprostatectomy with bypass), since there are no definite criteria with regards to therapy due to the low incidence of these tumours. Only three of the 11 patients with malignant neoplasms are still alive. All the others died within one year of diagnosis, an evidence of the aggressiveness of these tumours. These cases were considered primitive bladder tumours once it was concluded that there was no relation with any previous or simultaneous transitional neoplasms and that there had been no primitive tumour in a different organ.

Materials and Methods: In 27 cases of exstrophy, we measured the distance between the lowermost inguinal skin crease to the root of the penis (clitoris (B and the distance between the penis (clitoris and the scrotum (labia majora (C. These were compared with age, height and XP distance (distance between xiphisternum and symphysis pubis matched control group of normal children. The distance between the lowermost inguinal skin crease and the penis (clitoris (A was measured in control group. Results: The observation was A = B + C. This implies that in exstrophy bladder, the position of the penis (clitoris has moved cephalad from the lower border of A to the junction of B and C. Conclusion: Based on the observations, we postulate that abnormal origin of genital tubercle may be the cause of exstrophy bladder. The abnormal origin of primordia of the genital tubercle in more cephalad direction than normal causes wedge effect, which will interfere with the medial migration of the mesoderm as well as the midline approximation of mesodermal structures in the lower abdominal wall, thereby resulting in the exstrophy of bladder.

    Several molecular and genetic studies have provided new perspectives on the histologic classification of bladder tumors. Recent developments in the field of molecular mutational pathway analyses based on next generation sequencing technology together with classic data derived from the description of mutations in the FGFR3 (fibroblast growth factor receptor 3) gene, mutations on TP53 gene, and cDNA technology profiling data gives support to a differentiated taxonomy of bladder cancer. All these changes are behind the use of non-traditional approach to therapy of bladder cancer patients and are ready to change our daily practice of uro-oncology. The observed correlation of some molecular alterations with tumor behavior and the identification of their targets at cellular level might support the use of molecular changes together with morphological data to develop new clinical and biological strategies to manage patients with urothelial cancer. The current review provides comprehensive data to support personalized therapy for bladder cancer based on an integrated approach including pathologic and clinical features and molecular biology.

  16. Salvage of Failed Local and Regional Flaps with Porcine Urinary Bladder Extracellular Matrix Aided Tissue Regeneration

    2013-01-01

    Full Text Available Local and regional flap failure can be a major complication in head and neck surgery, which continue to be prevalent for a number of reasons including poor flap design, improper surgical technique, and poor tissue vascularity. Dealing with these failures can be quite difficult. Surgical debridement, flap revisions, and complex wound regimens are necessitated to reestablish appropriate tissue coverage. Traditional use of wet to dry dressing to enable proper wound granulation and possible closure with additional flaps or skin grafts is a laborious process. Such treatments place great time burdens on the patient, physicians, and nurses. Because the face and neck possess a complex three-dimensional topography, wound dressings are inherently complex to design and change. Many patients also require postoperative treatments such as radiation and chemotherapy to treat aggressive malignancies, and delay in wound healing leads to a delay in adjuvant treatment. Recently, advances in regenerative medicine, specifically xenogeneic extracellular matrix compounds, have been shown to promote tissue growth while limiting scar tissue formation (Badylak 2004. To our knowledge, this paper is the first case series using the porcine extracellular matrix bioscaffold (MatriStem ACell, Columbia, MD, USA to salvage flaps with extensive wound breakdown on the face and neck.

    Radical neck dissection was the golden standard of treatment for cervical nodes in head and neck tumors. From the seventies, the preservation of the spinal accessory nerve has become increasingly popular in order to improve the functional result of the neck dissections. The aim of this study was to assess the degree of functional disability associated with each type of neck dissection and the value of anatomical references for dissection of the spinal accessory nerve. One hundred twenty seven patients were evaluated 1 month and 1 year after radical, functional or supraomohyoid neck dissection with a questionnaire and a physical examination. Anatomical measurements of the spinal accessory nerve were performed in 20 patients. We found considerable or severe shoulder dysfunction in 7%, 34% and 51% respectively of patients in whom supraomohyoid, functional and radical neck dissections were performed. Furthermore 49% of patients having undergone a radical neck dissection had little or no symptoms. Sacrifice of the spinal accessory nerve in radical neck dissection may lead to shoulder dysfunction. A functional disability may also be associated, although in a less extent, with any neck dissection in which the spinal accessory nerve is dissected and placed in traction. There is a large variation in the degree of functional disability and pain in patients with similar neck dissections. The course of the spinal accessory nerve in the neck makes it particularly vulnerable to injury during the dissection near the sternocleidomastoid muscle and in the posterior cervical triangle.

  18. Bladder sensory desensitization decreases urinary urgency

    2007-06-01

    Full Text Available Abstract Background Bladder desensitization has been investigated as an alternative treatment for refractory detrusor overactivity. Most open and controlled clinical trials conducted with intravesical RTX showed that desensitization delays the appearance of involuntary detrusor contractions during bladder filling and decreases the number of episodes of urgency incontinence. Urgency is being recognised as the fundamental symptom of overactive bladder (OAB, a symptomatic complex which recent epidemiological studies have shown to affect more than 10% of the Western population. As anti-muscarinic drugs, the first line treatment for OAB, are far from being able to fully control urgency, the opportunity to test other therapeutic approaches is created. The present work was, therefore, designed as an exploratory investigation to evaluate the effect of bladder desensitization on urinary urgency. Methods Twenty-three OAB patients with refractory urgency entered, after given informed consent, a 30 days run-in period in which medications influencing the bladder function were interrupted. At the end of this period patients filled a seven-day voiding chart where they scored, using a 0–4 scale, the bladder sensations felt before each voiding. Then, patients were instilled with 100 ml of 10% ethanol in saline (vehicle solution and 30 days later a second seven-day voiding chart was collected. Finally, patients were instilled with 100 ml of 50 nM RTX in 10% ethanol in saline. At 1 and 3 months additional voiding charts were collected. At the end of the vehicle and 3 months period patients were asked to give their subjective impression about the outcome of the treatment and about the willingness to repeat the previous instillation. Results At the end of the run-in period the mean number of episodes of urgency per week was 71 ± 12 (mean ± SEM. After vehicle instillation, the mean number of episodes of urgency was 56 ± 11, but only 4 patients (17% considered

    1999-07-15

    This plan describes the performance standards met and closure activities conducted to achieve clean closure of the 2401-W Waste Storage Building (2401-W) (Figure I). In August 1998, after the last waste container was removed from 2401-W, the U.S. Department of Energy, Richland Operations Office (DOE-RL) notified Washington State Department of Ecology (Ecology) in writing that the 2401-W would no longer receive waste and would be closed as a Resource Conservation and Recovery Act (RCRA) of 1976 treatment, storage, and/or disposal (TSD) unit (98-EAP-475). Pursuant to this notification, closure activities were conducted, as described in this plan, in accordance with Washington Administrative Code (WAC) 173-303-610 and completed on February 9, 1999. Ecology witnessed the closure activities. Consistent with clean closure, no postclosure activities will be necessary. Because 2401-W is a portion of the Central Waste Complex (CWC), these closure activities become the basis for removing this building from the CWC TSD unit boundary. The 2401-W is a pre-engineered steel building with a sealed concrete floor and a 15.2-centimeter concrete curb around the perimeter of the floor. This building operated from April 1988 until August 1998 storing non-liquid containerized mixed waste. All waste storage occurred indoors. No potential existed for 2401-W operations to have impacted soil. A review of operating records and interviews with cognizant operations personnel indicated that no waste spills occurred in this building (Appendix A). After all waste containers were removed, a radiation survey of the 2401-W floor for radiological release of the building was performed December 17, 1998, which identified no radiological contamination (Appendix B).

    The purpose of this review is to critically analyze the relationship between symptoms of abnormal emptying of the bladder, urgency, pelvic pain, anorectal dysfunction and pelvic organ prolapse (POP) and to present evidence in order to show how many of the above mentioned symptoms can be cured or substantially improved by repair of specific pelvic ligaments. In this review, we provide evidence to show how often these dysfunctions occur and how they can be cured in 42-94% by appropriate pelvic floor surgery in the longer term, up to 2 years. Laxity in ligaments and/or vaginal membrane due to damaged connective tissue may prevent the normal opening and closure mechanism of urethra and anus, because muscles need finite lengths to contract properly. Hypermobility of the apex can irritate the pelvic plexus causing chronic pelvic pain. In consequence, dysfunctions as abnormal emptying of the bladder, urgency, pelvic pain, fecal incontinence and obstructed defecation can occur in women with different degrees of POP. In conclusion, it has to be recognized that women bothered by these symptoms should be examined for POP and appropriately advised for possibility of cure by pelvic floor surgery after careful selection.

    2006-02-14

    Lawrence Livermore National Laboratory operated two Class II surface impoundments that stored wastewater that was discharged from a number of buildings located on the Site 300 Facility (Site 300). The wastewater was the by-product of explosives processing. Reduction in the volume of water discharged from these buildings over the past several years significantly reduced the wastewater storage needs. In addition, the impoundments were constructed in 1984, and the high-density polyethylene (HDPE) geomembrane liners were nearing the end of their service life. The purpose of this project was to clean close the surface impoundments and provide new wastewater storage using above ground storage tanks at six locations. The tanks were installed and put into service prior to closure of the impoundments. This Clean Closure Report (Closure Report) complies with State Water Resources Control Board (SWRCB) Section 21400 of the California Code of Regulations Title 27 (27 CCR section 21400). As required by these regulations and guidance, this Closure Report provides the following information: (1) a brief site description; (2) the regulatory requirements relevant to clean closure of the impoundments; (3) the closure procedures; and (4) the findings and documentation of clean closure.

    In this paper, we define Watson-Crick context-free grammars, as an extension of Watson-Crick regular grammars and Watson-Crick linear grammars with context-free grammar rules. We show the relation of Watson-Crick (regular and linear) grammars to the sticker systems, and study some of the important closure properties of the Watson-Crick grammars. We establish that the Watson-Crick regular grammars are closed under almost all of the main closure operations, while the differences between other Watson-Crick grammars with their corresponding Chomsky grammars depend on the computational power of the Watson-Crick grammars which still need to be studied.

    We estimate the effect of exposure to plant closure on crime using an individual-level panel data set containing criminal charges for all unmarried and employed Norwegian men below the age of 40. Men originally employed in plants that subsequently closed are 14 percent more likely to be charged of a crime than comparable men in stable plants. There is no difference in charge rates prior to closure, supporting a causal interpretation of our result. Within crime categories, we find no effect of...

    Bladder masses are represented by either benign or malignant entities. Malignant bladder tumors are frequent causes of disease and death in western countries. However, in children they are less common. Additionally, different features are found in childhood, in which non epithelial tumors are more common than epithelial ones. Rhabdomyosarcoma is the most common pediatric bladder tumor, but many other types of lesions may be found, such as malignant rhabdoid tumor (MRT), inflammatory myofibroblastic tumor and neuroblastoma. Other rarer tumors described in literature include urothelial carcinoma and other epithelial neoplasms. Rhabdomyosarcoma is associated to a variety of genetic syndromes and many genes are involved in tumor development. PAX3-FKHR and PAX7-FKHR (P-F) fusion state has important implications in the pathogenesis and biology of RMS, and different genes alterations are involved in the pathogenesis of P-F negative and embryonal RMS, which are the subsets of tumors most frequently affecting the bladder. These genes include p53, MEF2, MYOG, Ptch1, Gli1, Gli3, Myf5, MyoD1, NF1, NRAS, KRAS, HRAS, FGFR4, PIK3CA, CTNNB1, FBXW7, IGF1R, PDGFRA, ERBB2/4, MET, BCOR. Malignant rhabdoid tumor (MRT) usually shows SMARCB1/INI1 alterations. Anaplastic lymphoma kinase (ALK) gene translocations are the most frequently associated alterations in inflammatory myofibroblastic tumor (IMT). Few genes alterations in urothelial neoplasms have been reported in the paediatric population, which are mainly related to deletion of p16/lnk4, overexpression of CK20 and overexpression of p53. Here, we reviewed available literature to identify genes associated to bladder malignancies in children and discussed their possible relationships with these tumors. PMID:27013922

    Full Text Available Abstract Objectives The authors present a novel approach to nonresectional therapy in major hepatic trauma utilizing intraabdominal perihepatic vacuum assisted closure (VAC therapy in the porcine model of Grade V liver injury. Methods A Grade V injury was created in the right lobe of the liver in a healthy pig. A Pringle maneuver was applied (4.5 minutes total clamp time and a vacuum assisted closure device was placed over the injured lobe and connected to suction. The device consisted of a perforated plastic bag placed over the liver, followed by a 15 cm by 15cm VAC sponge covered with a nonperforated plastic bag. The abdomen was closed temporarily. Blood loss, cardiopulmonary parameters and bladder pressures were measured over a one-hour period. The device was then removed and the animal was euthanized. Results Feasibility of device placement was demonstrated by maintenance of adequate vacuum suction pressures and seal. VAC placement presented no major technical challenges. Successful control of ongoing liver hemorrhage was achieved with the VAC. Total blood loss was 625 ml (20ml/kg. This corresponds to class II hemorrhagic shock in humans and compares favorably to previously reported estimated blood losses with similar grade liver injuries in the swine model. No post-injury cardiopulmonary compromise or elevated abdominal compartment pressures were encountered, while hepatic parenchymal perfusion was maintained. Conclusion These data demonstrate the feasibility and utility of a perihepatic negative pressure device for the treatment of hemorrhage from severe liver injury in the porcine model.

    Neck pain is associated with changes in neuromuscular control of cervical muscles. Violin and viola playing requires good function of the flexor muscles to stabilize the instrument. This study investigated the flexor muscle behaviour in violin/viola players with and without neck pain using the craniocervical flexion test (CCFT). In total, 12 violin/viola players with neck pain, 21 violin/viola players without neck pain in the preceding 12 weeks and 21 pain-free non-musicians were included. Activity of the sternocleidomastoid muscles (SCM) was measured with surface electromyography (EMG) during the CCFT. Violin/viola players with neck pain displayed greater normalised SCM EMG amplitudes during CCFT than the pain-free musicians and non-musicians (P neck pain in violinists/violists is associated with altered behaviour of the superficial neck flexor muscles consistent with neck pain, despite the specific use of the deep and superficial neck flexors during violin playing.

    Sampling of the urinary bladder (UB) in radical cystectomy specimens is usually performed by obtaining sections through the lesions taken in rather random planes. The technique is hindered by the difficulty in identifying the anatomical relationship of the tumor with the remaining urinary bladder. Fifty radical cystectomy specimens were bisected in the horizontal plane at the middle portion of the UB then fixed without tissue stretching in 10% buffered formalin for at least 24 hours. The UBs were serially sectioned in parallel horizontal planes from the UB neck to the dome into rings of 3 to 10 mm thickness. The sections were orderly arranged and photographed. At least one ring of tissue was entirely submitted along with areas of interest or representative areas. Our proposed technique of transverse sections results in a mild increase in the number of sections submitted for microscopic examination. The advantages of our methods are (a) consistency and ease of sampling that help the microscopic-macroscopic correlation, (b) suitability for gross examination and for determining depth of invasion and largest tumor diameter, (c) improved identification of satellite lesions, and (d) suitability for neoplastic mapping and suitability for reexamination. The technique was validated by comparing with results of current technique. © The Author(s) 2015.

    2005-01-01

    Objective: To study recurrence factors and set up a model to evaluate the prognosis of patients with bladder cancer.Methods: An analysis on recurrence-related factors was made by Cox's proportional hazards model analysis and logistic multiple linear regression model analysis in 212 patients with transitional cell carcinoma treated surgically from 1995~2001.These factors included clinical and pathologic figures. Results: The most important factor is metastasis to the regional lymph nodes, the Hazards ratio is 6.6 (P=0.0004), followed by multiple tumors (Hr=2.255, P<0.0001), tumor in trigone and bladder neck (Hr=2.053, P<0.0001), stage (Hr=2.057, P<0.0001), grade (Hr=1.569, P=0.0081), intravesical chemotherapeutic instillations (Hr-0.559, P=0.0011) and hematuria (Hr=0.762, P=0.0076). A predicting equation was established, and the predicting values were calculated according to the individual features of patients. The predicting and actual values were compared, and the sensitivity, specificity and overall concordance were 83.5%, 67.6% and 80.1% respectively. Conclusion:The evaluation of prognosis could be made quite accurately based on these factors.

  10. WHO/ISUP classification of the urothelial tumors of the urinary bladder

    2005-09-01

    Full Text Available Background: The authors present the current classification of urothelial neoplasms of the urinary bladder. The classification of urothelial tumors of the urinary bladder of 1973 was despite some imperfection relatively successfuly used for more than thirty years. The three grade classification of papillary urothelial tumors without invasion has been based on evaluation of variations in architecture of covering epithelium and tumor cell anaplasia. As reccomended by the International Society of Urological Pathologists (ISUP, the World Health Organisation (WHO accepted the new WHO/ ISUP classification in 1998 that was revised in 2002 and finally published in 2004. With intention to avoid unnecessary diagnosis of cancer in patients having papillary urothelial tumors with rare invasive or metastastatic growth, this classification introduced a new entity, the papillary urothelial neoplasia of low malignant potential (PUNLMP. The additional change in classification was the division of invasive urothelial neoplasms only to low and high grade urothelial carcinomas.Conclusions: The authors’ opinion is that although the old classification is not recommended for use anymore the new one is not solving the elementary reproaches to previous classification such as terminological unsuitability and insufficient scientific reasoning. Our proposed solution in classification of papillary urothelial neoplasms would be the application of criteria analogous to that used in diagnostics of papillary noninvasive tumors of the head and neck or alimentary tract.

    Afatinib is a highly selective, irreversible inhibitor of the epidermal growth factor receptor (EGFR) and human EGFR 2 (HER-2). Although preclinical and clinical studies have indicated that afatinib has antitumor activity and clinical efficacy in non-small cell lung carcinoma, head and neck squamous cell carcinoma and breast cancer, there are few studies investigating its inhibitory effect on human bladder carcinoma cells. In this study, the antitumor effect of afatinib was investigated on the T24 bladder cancer cell line. The T24 bladder cancer cell line was treated with afatinib at various concentrations (0, 1, 5, 10 and 20 µmol/l). MTT assay was used to estimate the proliferation of the T24 cells; flow cytometric analysis was used to estimate the effect of afatinib on T24 cell apoptosis; cell invasion ability was assessed by a Transwell invasion assay; and western blot analysis was used to detect the expression of Bcl-2, Bax, Akt, extracellular-signal-regulated kinase (ERK)1/2, matrix metalloproteinase (MMP)-2 and MMP-9. The MTT assay demonstrated that afatinib inhibited the proliferation of T24 cells in a dose- and time-dependent manner. Flow cytometric analysis revealed that the cell apoptosis rate increased as the concentration of afatinib increased. The cell invasion assay indicated that afatinib treatment significantly inhibited the invasive behavior of T24 cells in a dose-dependent manner. Western blot analysis showed that with increasing afatinib concentrations, Bcl-2, phosphorylated (p)-ERK1/2, p-Akt, MMP-2 and MMP-9 expression levels were significantly decreased, whereas total (t)-ERK1/2 and t-Akt expression levels remained basically unchanged, and Bax expression levels were greatly increased. The results indicate that afatinib inhibits the proliferation and invasion of T24 cells in vitro and induces the apoptosis of these cells by inhibiting the EGFR signaling network.

    2011-01-01

    Recently, cutting planes derived from maximal lattice-free convex sets have been studied intensively by the integer programming community. An important question in this research area has been to decide whether the closures associated with certain families of lattice-free sets are polyhedra. For a long time, the only result known was the celebrated theorem of Cook, Kannan and Schrijver who showed that the split closure is a polyhedron. Although some fairly general results were obtained by Andersen, Louveaux and Weismantel [An analysis of mixed integer linear sets based on lattice point free convex sets, Math. Oper. Res. 35, (2010) pp. 233--256], some basic questions have remained unresolved. For example, maximal lattice-free triangles are the natural family to study beyond the family of splits and it has been a standing open problem to decide whether the triangle closure is a polyhedron. In this paper, we resolve this by showing that the triangle closure is indeed a polyhedron, and its number of facets can be ...

  20. 300 Area Process Trenches Closure Plan

    1994-08-15

    Since 1987, Westinghouse Hanford Company has been a major contractor to the US Department of Energy, Richland Operations Office and has served as co-operator of the 300 Area Process Trenches, the waste management unit addressed in this closure plan. For the purposes of the Resource Conservation and Recovery Act, Westinghouse Hanford Company is identified as ``co-operator.`` The 300 Area Process Trenches Closure Plan (Revision 0) consists of a Resource Conservation and Recovery Act Part A Dangerous Waste Permit Application, Form 3 and a Resource Conservation and Recovery Act Closure Plan. An explanation of the Part A Permit Application, Form 3 submitted with this document is provided at the beginning of the Part A Section. The closure plan consists of nine chapters and six appendices. The 300 Area Process Trenches received dangerous waste discharges from research and development laboratories in the 300 Area and from fuels fabrication processes. This waste consisted of state-only toxic (WT02), corrosive (D002), chromium (D007), spent halogenated solvents (F001, F002, and F003), and spent nonhalogented solvent (F005). Accurate records are unavailable concerning the amount of dangerous waste discharged to the trenches. The estimated annual quantity of waste (item IV.B) reflects the total quantity of both regulated and nonregulated waste water that was discharged to the unit.

  14. Head and neck position sense.

    Science.gov (United States)

    Armstrong, Bridget; McNair, Peter; Taylor, Denise

    2008-01-01

    Traumatic minor cervical strains are common place in high-impact sports (e.g. tackling) and premature degenerative changes have been documented in sports people exposed to recurrent impact trauma (e.g. scrummaging in rugby) or repetitive forces (e.g. Formula 1 racing drivers, jockeys). While proprioceptive exercises have been an integral part of rehabilitation of injuries in the lower limb, they have not featured as prominently in the treatment of cervical injuries. However, head and neck position sense (HNPS) testing and re-training may have relevance in the management of minor sports-related neck injuries, and play a role in reducing the incidence of ongoing pain and problems with function. For efficacious programmes to be developed and tested, fundamental principles associated with proprioception in the cervical spine should be considered. Hence, this article highlights the importance of anatomical structures in the cervical spine responsible for position sense, and how their interaction with the CNS affects our ability to plan and execute effective purposeful movements. This article includes a review of studies examining position sense in subjects with and without pathology and describes the effects of rehabilitation programmes that have sought to improve position sense. In respect to the receptors providing proprioceptive information for the CNS, the high densities and complex arrays of spindles found in cervical muscles suggest that these receptors play a key role. There is some evidence suggesting that ensemble encoding of discharge patterns from muscle spindles is relayed to the CNS and that a pattern recognition system is used to establish joint position and movement. Sensory information from neck proprioceptive receptors is processed in tandem with information from the vestibular system. There are extensive anatomical connections between neck proprioceptive inputs and vestibular inputs. If positional information from the vestibular system is inaccurate or

  15. Bladder Smooth Muscle Cells Differentiation from Dental Pulp Stem Cells: Future Potential for Bladder Tissue Engineering

    Directory of Open Access Journals (Sweden)

    Bing Song

    2016-01-01

    Full Text Available Dental pulp stem cells (DPSCs are multipotent cells capable of differentiating into multiple cell lines, thus providing an alternative source of cell for tissue engineering. Smooth muscle cell (SMC regeneration is a crucial step in tissue engineering of the urinary bladder. It is known that DPSCs have the potential to differentiate into a smooth muscle phenotype in vitro with differentiation agents. However, most of these studies are focused on the vascular SMCs. The optimal approaches to induce human DPSCs to differentiate into bladder SMCs are still under investigation. We demonstrate in this study the ability of human DPSCs to differentiate into bladder SMCs in a growth environment containing bladder SMCs-conditioned medium with the addition of the transforming growth factor beta 1 (TGF-β1. After 14 days of exposure to this medium, the gene and protein expression of SMC-specific marker (α-SMA, desmin, and calponin increased over time. In particular, myosin was present in differentiated cells after 11 days of induction, which indicated that the cells differentiated into the mature SMCs. These data suggested that human DPSCs could be used as an alternative and less invasive source of stem cells for smooth muscle regeneration, a technology that has applications for bladder tissue engineering.

    Full Text Available Carcinoma gall bladder is a very aggressive disease with poor outcomes. Despite achievements in the field of advanced imaging techniques, there is a very high mortality rate of the disease Cancer is the second most common disease in India responsible for maximum mortality with about 0.3 million deaths per year. The magnitude of cancer problem in the Indian Sub-continent (sheer numbers is increasing due to poor to moderate living standards and inadequate medical facilities. Women are more commonly affected than men. The peak incidence occurs in people in their 60s, but the disease age range is from 29 to 90 years of age and there is great geographic and ethnic variation. Carcinoma gall bladder, a disease of old age, is now found in the younger age group and presents with greater ferocity.

    Cabrera, T; Pedrajas, G; Cozar, J M; Garrido, A; Vicente, J; Tallada, M; Garrido, F

    2003-10-01

    HLA class I molecules are frequently lost in a large variety of human carcinomas, possibly because of T-cell immune selection of major histocompatibility complex class I deficient tumor variants. We report that this phenomenon is also a frequent event in bladder carcinomas. Of a total of 72 bladder carcinomas, 72% of the tumors had at least one alteration in HLA class I expression. These altered HLA class I phenotypes were classified as total HLA class I loss (25%; phenotype I); HLA-A or/and HLA-B locus-specific loss (12%; phenotype III); and HLA class I allelic loss (35%; phenotype II or IV). Comparison of histopathological parameters with HLA class I expression showed a statistically significant relationship with the degree of differentiation and tumor recurrence.

    The human transcription factor SOX4 was 5-fold up-regulated in bladder tumors compared with normal tissue based on whole-genome expression profiling of 166 clinical bladder tumor samples and 27 normal urothelium samples. Using a SOX4-specific antibody, we found that the cancer cells expressed...... strongly impaired cell viability and promoted apoptosis. To characterize downstream target genes and SOX4-induced pathways, we used a time-course global expression study of the overexpressed SOX4. Analysis of the microarray data showed 130 novel SOX4-related genes, some involved in signal transduction (MAP......2K5), angiogenesis (NRP2), and cell cycle arrest (PIK3R3) and others with unknown functions (CGI-62). Among the genes regulated by SOX4, 25 contained at least one SOX4-binding motif in the promoter sequence, suggesting a direct binding of SOX4. The gene set identified in vitro was analyzed...

  20. Neoadjuvant chemotherapy for invasive bladder cancer.

    Science.gov (United States)

    Sonpavde, Guru; Sternberg, Cora N

    2012-04-01

    Neoadjuvant cisplatin-based combination chemotherapy is an established standard for resectable muscle-invasive bladder cancer, a disease with a pattern of predominantly distant and early recurrences. Pathologic complete remission appears to be an intermediate surrogate for survival when employing combination chemotherapy. Moreover, baseline host and tumor tissue studies may enable the discovery of biomarkers predictive of activity. The neoadjuvant setting also provides a window of opportunity to evaluate novel biologic agents or rational combinations of biologic agents to obtain a signal of biologic activity. The residual tumor after neoadjuvant therapy may be exploited to study the mechanism of action and resistance. Cisplatin-ineligible patients warrant the evaluation of tolerable neoadjuvant regimens. Given that bladder cancer is characterized by initial localized presentation in the vast majority of cases, the paradigm of neoadjuvant therapy may expedite the development of novel systemic agents.

  1. Bladder Cancer in an Inguinoscrotal Vesical Hernia

    Directory of Open Access Journals (Sweden)

    Lucas Regis

    2012-01-01

    Full Text Available We present the case of a 79-year-old male who, due to hematuria, underwent cystoscopy that showed a lesion in the bladder dome. Transurethral resection was attempted, but access to the tumor by this route was impossible. Given the findings, a body CT scan was performed showing an inguinoscrotal hernia with vesical carcinoma contained. Open surgical treatment of the vesical carcinoma contained within the inguinoscrotal hernia was performed in conjunction with the hernia repair. The anatomical pathology report confirmed a high-grade urothelial carcinoma (stage pT2b with a free resection margin of <1 mm. Adjuvant radiotherapy was selected for subsequent treatment. The presence of bladder tumor in an inguinoscrotal hernia is an uncommon finding and a diagnostic delay can be assumed. The initial therapeutic plan may need to be changed from the usual approaches due to the atypical presentation.

    Although the functional merits of preserving cervical nerves in neck dissection for head and neck cancer have been reported, the oncologic safety has not yet been determined. Therefore, the purpose of this study was to evaluate the safety of cervical nerve preservation. A retrospective chart review was performed on patients with head and neck cancer who had been treated by neck dissection between 2009 and 2014 at Kyoto Medical Center. Management of cervical nerves and clinical results were analyzed. A total of 335 sides of neck dissection had been performed in 222 patients. Cervical nerves were preserved in 175 neck sides and resected in 160 sides. The 5-year overall survival (OS) rate calculated by the Kaplan-Meier method was 71%. The 5-year neck control rate was 95% in cervical nerve preserved sides and 89% in cervical nerve resected sides. Preserving cervical nerves in neck dissection is oncologically safe in selected cases. © 2017 Wiley Periodicals, Inc.

  4. Oncolytic Viruses in the Treatment of Bladder Cancer

    Directory of Open Access Journals (Sweden)

    Kyle G. Potts

    2012-01-01

    Full Text Available Bladder carcinoma is the second most common malignancy of the urinary tract. Up to 85% of patients with bladder cancer are diagnosed with a tumor that is limited to the bladder mucosa (Ta, T1, and CIS. These stages are commonly termed as non-muscle-invasive bladder cancer (NMIBC. Although the treatment of NMIBC has greatly improved in recent years, there is a need for additional therapies when patients fail bacillus Calmette-Guérin (BCG and chemotherapeutic agents. We propose that bladder cancer may be an ideal target for oncolytic viruses engineered to selectively replicate in and lyse tumor cells leaving normal cells unharmed. In support of this hypothesis, here we review current treatment strategies for bladder cancer and their shortcomings, as well as recent advancements in oncolytic viral therapy demonstrating encouraging safety profiles and antitumor activity.

    Bladder rupture following caesarian section is well documented complications. Intraperitoneal bladder rupture following normal vaginal delivery is very rare. Hereby, we present a case report of intraperitoneal bladder rupture presented late following normal vaginal delivery. We report a case of spontaneous intraperitoneal urinary bladder rupture following uneventful outlet forceps delivery in a 22-year-old primi gravid woman with gestational diabetes mellitus and fetal macrosomia who presented with large urinary ascites, anuria and renal failure. Emergent exploratory laparotomy with repair of the intraperitoneal bladder rupture helped to prevent its potential complications. Postpartum patients who undergo episiotomy or perineal repair may land up in unnoticed urinary retention which may rarely terminate in spontaneous urinary bladder rupture. Awareness of its manifestations amongst emergency physician would help to initiate appropriate timely management.

    Full Text Available Paragangliomas of the urinary bladder are very rare. To date, there are no reliable methods for predicting their clinical behavior, so long-term follow-up is required. We describe a paraganglioma of the urinary bladder in a 32-year-old male who presented with painless gross hematuria. Abdominal ultrasonography revealed a protruding mass with hematoma over the right lateral wall of the urinary bladder. The tumor was not completely resected by transurethral resection of bladder tumor (TURBT due to intermingling with the bladder wall. Follow-up I131-metaiodobenzylguanidine was performed 3 weeks after surgery and suspected incomplete resection lesions were noted. Histologic examination of the tumor indicated paraganglioma of the urinary bladder. We also provide a brief review of the literature for comparison.

    Full Text Available Objective: to assess the results of surgical treatment of patients with the intestinal urinary bladder, to characterize its early and late postoperative complications, and to develop their correction tactics.  Subjects and methods. The results of treatment in 198 patients who had undergone ileocystoplasty were analyzed.  Results. The developed diagnostic approach and the determined examination periods could reduce the number of late postoperative complications of ileocystoplasty: acute and chronic pyelonephritis from 19.4 to 7.6%, urolithiasis from 17.2 to 1.9%, bladder dysfunction from 25.8 to 7.6%, and metabolic acidosis from 4.3 to 1.9%, and prevent the development of ureterovesical anastomosis stricture.  Conclusion. Radical cystectomy with the ileoplasty using an isolated segment of the ileum in patients with invasive urinary bladder carcinoma has been the operation of choice no longer; it has become an essential surgical adjunct. This method permits overall 5-year survival to be achieved in 69.7% of patients.

    Full Text Available Neck pain and migraine are common diseases. Neck pain seldom occurs in a patient with migraine. However, the relationship between migraine and neck pain has been inadequately investigated.Objective: to analyze neck pain in patients with migraine to determine possible comorbidity mechanisms of these diseases.Patients and methods. The investigation enrolled 63 patients with chronic migraine (CM and 40 with episodic migraine (EM diagnosed in accordance with the International Classification of Headache Disorders, 3rd edition (ICHD-3. Winking reflex (WR and nociceptive flexion reflex (NFR were examined to evaluate the function of antinociceptive systems.Results. In the patients with CM, neck pain was more common than in those with EM (53.03% versus 14.02%; and panful tenderness, sensitivity, and tension of neck muscles were more marked. There was also a significant reduction in WR and NFR thresholds. Neck pain was noted to be an integral component of the pathogenesis of CM in a large number of patients with this condition. The authors proposed several pathophysiological mechanisms of a relationship between migraine and neck pain. Neck muscles and craniovertebral junction areas serve as a source for the arrival of nociceptive pain pulses in the central nervous system (peripheral sensitization, promoting pain chronization. Muscle dysfunction in this area may be, in turn, a reflection of central sensitization and impaired descending pain control.

    Neck pain is very common. Age, female gender, obesity, and several physical and psychological work related factors increase the risk while physical activity appears to decrease it. Non-specific neck pain is most common but serious or specific illness must be ruled out and neural compression identified. Patients are encouraged to remain active and improve their ergonomics. Acute neck pain often disappears without any special treatment. Paracetamol is the primary pain medication. Multidisciplinary treatment is recommended if disabling pain has lasted for two months, and intensive muscle exercises in chronic neck pain. Progressive muscle weakness and myelopathy indicate a surgical assessment.

    To explore differences in bladder sensations between patients with overactive bladder (OAB) and healthy volunteers by evaluating self-consciousness, self-awareness and affective complaints. A prospective, observational study was performed comparing patients with OAB symptoms and healthy volunteers. During 3 days subjects filled out sensation-related bladder diaries (SR-BD), Self-Consciousness Questionnaires (SCS), Self-Awareness Questionnaire (SSAS) and the Hospital Anxiety and Depression Scale (HADS). The SSAS was filled out at the second void of the first day. In total, 134 participants were included (66 volunteers and 68 patients). Patients had lower voided volumes (193 mL vs 270 mL, P self-awareness than volunteers, indicating that OAB patients may attribute different values to body signals. Future research is required to elaborate our knowledge on the perceived sensations and labeling of emotions in OAB. © 2017 John Wiley & Sons Australia, Ltd.

    Full Text Available Bladder cancer is the seventh most common cancer in men in the world, it is the second most seen cancer after lung cancer and the first in urogenital tumours in Turkey. Many molecular epidemiologic studies have been reported to investigate the associations between the MTHFR C677T and A1298C polymorphisms and bladder cancer risk. In this report, a family with transitional bladder cancer have also MTHFR A1298C heterozygosity which supports the association between MTHFR variants and bladder cancer. This %uFB01nding should be further validated by prospective and larger studies with more diverse ethnic groups.

    Full Text Available Placenta percreta is a rare condition, which can lead to significant morbidity and potentially mortality. We present a case of a 38-year-old woman who presented at 24 weeks gestation with vaginal bleeding and was found to have complete placenta previa with placenta percreta invading the urinary bladder. Her hospital course was complicated by bilateral pulmonary emboli. She underwent an exploratory laparotomy, repeat Caesarean section, and total abdominal hysterectomy. Because of placental invasion into the bladder, the procedure was complicated by bladder and ureteral injuries for which urology carried out repair. Postoperatively, the patient had a persistent bladder leak until postoperative day #39.

    Full Text Available Bladder stones account for approximately 5% of all urinary system stones and are prevalent among children living in poor or rural regions. The symptoms and findings in children with bladder stones are usually urgency, frequency, incontinence, dysuria, pyuria, difficulty voiding, and fever, small caliber of urinary stream, lower abdominal pain and urinary intermittency. Most bladder stones are composed of calcium oxalate, followed by calcium phosphate, and they are usually larger than 2.5 cm in diameter. We present a case of a larger-than 2.5-cm bladder stone in a child.

    Radical cystectomy is a standard treatment of nonmetastatic, muscle-invasive bladder cancer. Treatment with trimodality therapy consisting of maximal transurethral resection of the bladder tumor followed by concurrent chemotherapy and radiation has emerged as a method to preserve the native bladder in highly motivated patients. Several factors can affect the likelihood of long-term bladder preservation after trimodality therapy and therefore should be taken into account when selecting patients. New radiation techniques such as intensity modulated radiation therapy and image-guided radiation therapy may decrease the toxicity of radiotherapy in this setting. Novel chemotherapy regimens may improve response rates and minimize toxicity.

    Augmentation cystoplasty is a successful surgical procedure for the management of neurogenic bladder in children in order to improve urodynamic parameters. The aim of this article is to describe urodynamic changes after augmentation cystoplasty in children with myelomeningocele. A descriptive cross-sectional study including children aged 8-16 years with a myelomeningocele operated on for augmentation cystoplasty surgery with sigmoid colon segments due to a neurogenic bladder from the years 2003-2013. A urodynamic study was conducted before and after the surgical procedure. Non-probabilistic sample of consecutive cases. Descriptive statistics with frequencies and percentages, medians, and ranges. Inferential intra-group comparison with the Wilcoxon test and inter-group with Mann-Whitney U. SPSS 20.0 statistical package. The study included 50 patients, of whom 25 were male and 25 were female, with a median age of 12 years (range, 6-15 years). Bladder capacity improved from 52.8% to 95.9% (p<0.001), uninhibited contractions 1.4-1.8, contraction intensity 47-8.5 (p<0.001), mean pre-surgical and post-surgical filling pressure 40.8cm H2O and 11.0cm H2O, respectively (p<0.001), mean emptying pressure 48.5 vs. 3.6cm H2O (p<0.001), and bladder accommodation 4.6 vs. 41.3cm H2O (p<0.001). Augmentation cystoplasty with sigmoid colon significantly improved urodynamic parameters, such as bladder accommodation and filling pressure in children with myelomeningocele-associated neurogenic bladder.

    Background Bioreactors are pivotal tools for generating mechanical stimulation in functional tissue engineering study.This study aimed to create a bioreactor that can simulate urinary bladder mechanical properties, and to investigate the effects of a mechanically stimulated culture on urothelial cells and bladder smooth muscle cells.Methods We designed a bioreactor to simulate the mechanical properties of bladder. A pressure-record system was used to evaluate the mechanical properties of the bioreactor by measuring the pressure in culture chambers. To test the biocompatibility of the bioreactor, viabilities of urothelial cells and smooth muscle cells cultured in the bioreactor under static and mechanically changed conditions were measured after 7-day culture. To evaluate the effect of mechanical stimulations on the vital cells, urethral cells and smooth muscle cells were cultured in the simulated mechanical conditions. After that, the viability and the distribution pattern of the cells were observed and compared with cells cultured in non-mechanical stimulated condition.Results The bioreactor system successfully generated waveforms similar to the intended programmed model while maintaining a cell-seeded elastic membrane between the chambers. There were no differences between viabilities of urothelial cells ((91.90±1.22)% vs. (93.14±1.78)%, P >0.05) and bladder smooth muscle cells ((93.41±1.49)% vs.(92.61±1.34)%, P >0.05). The viability of cells and tissue structure observation after cultured in simulated condition showed that mechanical stimulation was the only factor affected cells in the bioreactor and improved the arrangement of cells on silastic membrane.Conclusions This bioreactor can effectively simulate the physiological and mechanical properties of the bladder.Mechanical stimulation is the only factor that affected the viability of cells cultured in the bioreactor.

    manifested with hyperreflexia bladders, and all patients were treated with surgical procedures. During operation, collected bladder tissue samples including tissues of apex vesicae and tissues of bladder neck, and all tissues were enveloped with mineral wax. All tissues were detected for nNOS, iNOS, and eNOS respectively in tissues of apex vesicae and tissues of bladder neck,and with normal bladder tissues as control group (bladder tissues of hypospadia, 10 cases), and according to clinical features, to explore the expression of NOS, and to analyze the relationship among them. Results In normal apex vesicae tissues, all cases stained with nNOS, and distributed among bundles of smooth muscles, and surface of smooth muscles and interstitial tissue, histochemica;score (HS) 2.8-4.0 and 1.2-2.7. There were no stained cells in bladder tissues of iNOS, and HS was very low, HS:0-0. 4 and 0-0.1 ;eNOS mainly distributed in interstitial tissues in rarefaction manners, and mainly in vascular endothelial cell (VEC), and smooth muscles had no stainings the most expression among them was nNOS, and mainly distributed in bladder neck tissues. In neurogenic bladder tissues, the main expression of NOS type was iNOS, and nNOS decreased significantly. eNOS mainly expressed in VEC among interstitial tissues, and had no staining in smooth muscle cells and collagenoblast and rarefaction of microvessel in bladder tissues, and microvessel density decreased significantly than normal bladder tissues. Microvessal density(MVD) in bladder tisssus (6. 8± 3.2/100per square) was less than that in normal tissues (16.7±6.3/100 per square). Conclusions In normal bladder tissues, nNOS mainly distributes in bladder neck and urethra, and nitric oxide mainly derives from nNOS. Much more matrix fibers, fewer nitrogenergic nerves, and less nNOS expression are seen in neurogenic bladder interstitial tissue. There are more iNOS expressions in bladder tissues,and NO is mainly derived from iNOS, and it may play an

    The Royal United Hospital, Bath, admits approximately 550 patients with neck of femur fractures per year. The risks from returning to theatre for this patient group are often life-threatening. Post-operative wound ooze was noted to cause a significant rate of return to theatre, with increased lengths of stay and patient morbidity. A wound closure protocol was agreed by the consultant body. This information was disseminated by email and teaching sessions to all members of the multidisciplinary team, including surgeons, theatre staff and ortho-geriatricians. The plan-do-study-act model for improvement was used to reduce rates of returns to theatre for wound ooze. Interventions included cyclical teaching during each trainee rotation, updated inductions, posters, email reminders and scrub team involvement to open the protocol sutures unprompted. The primary outcome measure was returns to theatre for wound complications. Baseline data showed 4 returns to theatre over a two month period (4.40% of patients). Length of stay for each patient affected by wound ooze was also compared to the departmental mean. In the 6 month intervention period there was one return to theatre (0.36% of patients). The observed reduction saved the department an estimated £13,831 in length of stay alone. The standardisation of wound closure protocol, with continued reinforcement to all members of the multidisciplinary team, improves patient outcome in this group. Mobilising a group of clinicians across a variety of specialities, with one common goal, is highly effective for patients, improves multidisciplinary working and reduces cost.
