Acute urinary retention (AUR) in females is a poorly defined condition with undetermined epidemiology. This study aimed to evaluate female AUR in an outpatient population. One hundred and thirty-eight adult female outpatients who presented to the emergency room with symptoms of urinary retention were retrospectively analyzed. The women who were ultimately diagnosed with true, complete AUR were systematically reviewed for clinical characteristics and management. In this outpatient cohort with urinary retention complaints, only 23% of the patients were diagnosed with objective AUR. Detailed medical and urological history in addition to urogenital, neurological, and pelvic examinations was essential; urine analysis and pelvic ultrasonography were necessary as baseline investigations. Further radiological and urodynamic tests were required in a minority. Specific etiology was established in 77% of the patients, whereas there was more than one probable cause in 16% of the patients, and no specific cause was found in 6.5% of the patients. Bladder decompression and correction of the underlying cause helped 92.6% of the reviewed patients to eventually achieve spontaneous micturition. The proportion of true, complete AUR among female outpatients presenting to the emergency department was 23% following urological evaluation. Acute condition was resolved by urgent catheterization in all, and the majority of women had eventually resumed spontaneous voiding.

Full Text Available Atomoxetine is a well-studied non-stimulant treatment agent, and is also the first-choice non-stimulant drug for the conventional treatment of Attention Deficit Hyperactivity Disorder owing to its effectiveness and tolerability. Urinary retention is a type of urological emergency that is associated with the inability to urinate despite the bladder being full and a strong urge to urinate. It is known that urinary retention can also develop due to the use of anticholinergic drugs. In this manuscript, we present a 12-year-old male case who developed acute urinary retention in the period following atomoxetine treatment.

Urinary retention is uncommon in patients with herpes zoster and anogenital herpes simplex. Seven patients (four men, three women) with a mean age of 68.1 years (range, 35-84) with urinary retention due to herpes zoster (n = 6) or anogenital herpes simplex (n = 1) were studied. Six patients had unilateral skin eruption in the saddle area (S2-4 dermatome) and one patient with herpes zoster had a skin lesion in the L4-5 dermatome. All patients had detrusor areflexia without bladder sensation, and two of them had inactive external sphincter on electromyography at presentation. Clean intermittent catheterization was performed, and voiding function was recovered in 4-6 weeks (average, 5.4) in all patients. Urodynamic study was repeated after recovery of micturition in three patients, and they returned to normal on cystometrography and external sphincter electromyography. Acute urinary retention associated with anogenital herpes infection has been thought to occur when the meninges or sacral spinal ganglia were involved, and, in conclusion, this condition may be considered to be reversible.

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

Full Text Available An elderly male presented to the emergency department with acute urinary retention. He had poor flow of urine associated with serosanguinous discharge per urethra for 3 days duration. Earlier he underwent permanent metallic urethral stenting for post TURP bulbar urethral stricture. Plain X-ray of Pelvis showed an impacted calculus within the urethral stent in bulbar urethra. Urethrolitholapaxy was done with semirigid ureteroscope. Urethral stent was patent and well covered. Subsequently he had an uneventful recovery. We describe a unique case of acute urinary retention due to calculus impaction within a urethral stent.

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

Symptomatic benign prostatic hyperplasia: the role of 5-alpha-reductase inhibitors in the prevention of acute urinary retention and surgical therapy

Full Text Available Benign prostatic hyperplasia (BPH is a disease that affects over 50% of males aged 50 years or older. In men aged >80 years, the incidence is 90%. BPH occurs in 9-25% of males aged 40 to 79 years. Fifty percent of patients with BPH are symptomatic. The symptoms include reduced urinary flow, nocturia, defective bladder emptying, urinary hesitancy, and dysuria. Disease progression can be associated with acute urinary retention (AUR. Prostatic obstruction includes mechanical and dynamic components, the latter mediated by alpha-muscarinic receptors. Treatment with alpha-1-blockers (alfuzosin, doxazosin, tamsulosin, and terazosin leads to rapid amelioration of symptoms and urinary flow, usually within one or two weeks. The 5-alpha reductase inhibitors (5-ARIs are “disease-modifying drugs.” They control the growth of the prostate by blocking the conversion of testosterone into dihydrotestosterone (DHT. Finasteride is a 5–ARI that is selective for type 2 receptors. Dutasteride is a powerful inhibitor of both 5- alpha reductase isoforms (type 1 and 2 and produces more complete suppression of DHT synthesis than finasteride. Dutasteride also has a much longer half-life than finasteride (five weeks versus five to six hours. The authors review the results of clinical trials involving finasteride and dutasteride, with and without alpha-1-blockers, highlighting the important role of dutasteride in improving acute urinary retention and eliminating the need for surgical therapy.

To compare the safety and efficacy of combined therapy using sildenafil and tamsulosin for management of acute urinary retention (AUR) with tamsulosin alone in patients with benign prostate hyperplasia (BPH). 101 patients were enrolled in a randomized placebo-controlled study from June 2009 to April 2012. Patients presenting with an initial episode of spontaneous AUR underwent urethral catheterization and then prospectively randomized to receive tamsulosin 0.4 mg plus sildenafil 50mg in group A and tamsulosin 0.4 mg plus placebo in group B for three days. Urethral catheter was removed three days after medical treatment and patient's ability to void assessed at the day after catheter removal and seven days later. Patients who voided successfully were followed at least for three months. Mean age of patients was 59.64 ± 3.84 years in group A and 60.56 ± 4.12 years in group B (p value = 0.92). Mean prostate volume and mean residual urine were comparable between both groups (p value = 0.74 and 0.42, respectively). Fifteen patients in group A (success rate: 70%) and nineteen patients in group B (success rate: 62.7%) had failed trial without catheter (TWOC) at 7th day following AUR (p value = 0.3). No significant difference was noted between both groups regarding the rate of repeated AUR at one month and three month follow-up period (p = 0.07 and p = 0.45, respectively). It seems that combination therapy by using 5-phosphodiesterase inhibitor and tamsulosin has no significant advantages to improve urinary retention versus tamsulosin alone.

OBJECTIVES: To assess for predictors of outcome in patients presenting with acute urinary retention (AUR). METHODS: A study was performed in our unit to evaluate trial without catheter (TWOC) and successive management. We assessed for predictors of surgical or medical management, which included: age, volume drained at time of catheterisation, cause of retention, serum creatinine, success of trial of voiding, co-morbidities, prostate-specific antigen (PSA) and prostate size on digital rectal examination (DRE). RESULTS: 72 men were entered into the study over an 18-month period: 27 had a successful first TWOC, 20 patients had a second TWOC, and 6 were successful. In total, 31 of the 33 patients with a successful TWOC remained on alpha-blockers without a further episode of AUR within a minimum of 6 months\\' follow-up. Patients failing TWOC were managed by transurethral resection of the prostate (n = 22), long-term catheterisation (n = 15) or prostatic stents (n = 3), and 1 patient died prior to intervention. Three predictors were significant on multivariate analysis: PSA (>2.9 ng\\/ml), prostate size on DRE (large) and volume drained at time of catheterisation (>or=1,000 ml). CONCLUSION: Patients with elevated PSA (>2.9 ng\\/ml), a large prostate size on DRE and a volume drained at time of catheterisation >1,000 ml are best managed by surgical intervention, while those with volumes drained at time of catheterisation of <1,000 ml, a PSA

Acute urine retention induced by ceftriaxone

Kamal F Akl

2011-01-01

Full Text Available Ceftriaxone is known to cause biliary pseudolithiasis and, rarely, nephrolithiasis. When used in neonates receiving intravenous calcium, fatal lung and kidney calcifications occur. There is no satisfactory explanation for the pseudolithiasis, and the mechanism of stone formation remains unknown. Herein, we report a child with acute urinary retention (AUR secondary to ceftriaxone therapy. The AUR developed on the second hospital day. The urinary excretion of uric acid was elevated. In retrospect, there was a positive paternal family history of gout and stones. A positive family history of gout or stones is a pointer to the possibility of AUR or urolithiasis in patients on treatment with ceftriaxone. If urinary symptoms develop, it is worth checking for crystalluria. This will avoid many unnecessary investigations and procedures.

Conclusions. Taking into consideration the minimally invasive nature, favourable tolerability and absence of adverse effects, TUMT can be considered a method of choice in patients with BPH-triggered AUR and contraindications to major surgical treatments and general anaesthesia. Remote outcomes of TUMT may be evaluated as satisfactory, with good effects in 71.62% patients. However in prostatic volumes exceeding 85 cm3 and pronounced intravesical pattern of BPH growth the efficcacy of TUMT is arguable.

Ureterocele is a cystic dilation of the distal ureteral segment. The incidence in women ranges from 1/5,000 to 1/12,000. In adults, they are poorly diagnosed and are asymptomatic. Prolapse through the urethra is uncommon, and involves acute urine retention and a reducible vulvar tumour. Woman of 24 years old, two previous caesarean and two abortions. She had incomplete bladder emptying, intermittent voiding, bladder straining and tenesmus, three months before admission. After the voiding effort she presented with acute urine retention with sudden onset of tumour in the vulva. The tumour was manually reduced under regional anaesthesia. A cystoscopy was performed, finding an ischaemic de-roofing of the anterior wall of the ureterocele, causing vesicoureteral reflux grade IV. Surgical correction was performed with Cohen re-implantation and insertion of a double-J catheter. The catheter was removed 30 days later, with a successful post-operative course. Its aetiology is unclear, and most are diagnosed by ultrasound in the prenatal period. The clinical presentation is variable, from urinary tract infection to prolapse. Despite its size, it may cause complications such as ischaemic de-roofing, which if diagnosed soon may be resolved successfully, as with this patient. The results and treatment may be favourable when no renal impact or concomitant anatomical changes are present, as is the case of this patient. Copyright © 2015 Academia Mexicana de Cirugía A.C.

Psychogenic Urinary Retention in Children: A Case Report

Directory of Open Access Journals (Sweden)

Kong-Sang Wan

2010-10-01

Full Text Available Psychogenic urinary retention occurs relatively infrequently in children and is less common than in adults. The influence of psychogenic factors on voiding generally results in an irritative syndrome, but rarely in urinary retention. A definitive diagnosis is established by excluding other pathological conditions. Evaluation includes urine culture, renal echography, spine magnetic resonance imaging, voiding cysto-urethrography, intravenous pyelography, and uroflowmetry. Here, we report on a 6-year-old girl with a 1-month history of voiding difficulty. Urology studies, including urine culture, revealed Escherichia coli, which was not present in preadmission urine cultures. Renal ultrasound and radiological images showed no gross abnormalities or vesicoureteral reflux, but uroflowmetry showed a low flow rate with residual urine. The results of imaging studies and pediatric psychiatric consultation led to a diagnosis of psychogenic urinary retention combined with urinary tract infection. Urinary rehabilitation included intermittent catheterization, bladder training, and supportive psychotherapy, after which the patient recovered and was discharged.

Current epidemiological patterns of adverse events of clinical BPH remain unclear. We investigated trends in acute urinary retention (AUR) associated with BPH in a large, population-based cohort. We utilized the California Office of Statewide Health Planning and Development Database to examine 3 724 016 emergency room (ER) visits in California among men aged  50 years from 2007 to 2010. Outcomes included AUR for which BPH was the primary diagnosis, AUR for which BPH was a secondary diagnosis and urethral catheterization for AUR. We generated adjusted odds ratios (ORadj) using multivariate logistic regression to determine longitudinal trends. A total of 17 023 men presented with a diagnosis of BPH-associated AUR, the unadjusted incidence of which increased from 4.00 per 1000 ER visits in 2007 to 5.23 per 1000 ER visits in 2010 (PBPH-associated AUR increased substantially in a large and ethnically diverse male population of the United States.

Full Text Available Acute urinary retention (AUR in males is managed conventionally by hospital admission, alpha-adrenergic therapy, and trial without catheter. To reduce inpatient bed pressures, we set up a protocol to manage such patients in the community. We review our results in this paper. We performed a prospective study of male patients presenting to our acute admissions ward and Accident and Emergency department over 6 months. Patients with chronic urinary retention, macroscopic haematuria, sepsis, urinary tract infection, and/or serum creatinine >130 mmol/l were excluded from the study. Those enrolled were catheterised, commenced on alfuzosin (10 mg nocte, and discharged to the community. A trial without catheter (TWOC was performed 5—7 days later. QoL/IPSS, peak flow rate, and residual volume assessment were performed following successful TWOC 3 months later.Thirty-one male patients with a median age of 69 years were studied and the median residual volume following catheterisation was 900 ml. The aetiology of AUR was benign prostatic hyperplasia (BPH in 29 patients and constipation in the remaining 2 patients. TWOC was successful in 19 patients (61.3% following first TWOC, 26 (83.9% following second trial of voiding. The mean peak flow rate was 6.5 ml/sec and postvoid scan 165 ml, following an immediate TWOC. At 3 months follow-up, mean peak flow rate was 13.2 ml/sec, postvoid scan 26.5 ml, IPSS 4.5, and QoL score was 2. This study has shown that AUR can be managed safely and effectively in the community. Effective communication with the nurse urology specialist, general practitioner, and emergency department are crucial for the successful implementation of the protocol.

POSTOPERATIVE URINARY RETENTION AND EARLY REPOSITION OF TENSION-FREE VAGINAL TAPE

Marijan Lužnik

2003-12-01

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

Urinary catheterization and acute urinary retention increase the risk of urinary tract infection (UTI). Our study aimed to investigate the incidence of UTI following acute stroke at our stroke center (SC) and to assess urinary catheter-care practices among French SCs. Stroke patients hospitalized within 24h of stroke onset were prospectively enrolled between May and September 2013. Neurological deficit level was assessed on admission using the US National Institutes of Health Stroke Scale (NIHSS). Patients were followed-up until discharge. Indwelling urinary catheterization (IUC) was the only technique authorized during the study. An electronic survey was also conducted among French SCs to assess their practices regarding urinary catheterization in acute stroke patients. A total of 212 patients were included, with 45 (21.2%) receiving indwelling urinary catheters. The overall estimated incidence of UTI was 14.2%, and 18% among patients receiving IUC. On univariate analysis, IUC was significantly associated with older age, longer hospital stays and higher NIHSS scores. Of the 30 SCs that responded to our survey, 19 (63.3%) declared using IUC when urinary catheterization was needed. The main argument given to justify its use was that it was departmental policy to adopt this technique. Also, 27 participants (90%) stated that conducting a study to assess the impact of urinary catheterization techniques on UTI rates in acute stroke patients would be relevant. Our results are in accord with previously reported data and confirm the high burden of UTI among acute stroke subjects. However, no association was found between IUC and UTI on univariate analysis due to a lack of statistical power. Also, our survey showed high heterogeneity in catheter-use practices among French SCs, but offered no data to help determine the best urinary catheterization technique. Urinary catheterization is common after acute stroke and a well-known risk factor of UTI. However, as high

There has been no consensus on the best catheterization strategy for the management of postoperative urinary retention. A prospective randomized trial was undertaken to establish the best practice guidelines for the management of postoperative urinary retention. The authors also evaluated the contemporary incidence of urinary retention following different categories of general surgery and examined risk factors associated with its occurrence. All patients who underwent elective inpatient surgery between January 2002 and June 2003 were recruited into the study. Patients who developed postoperative urinary retention were randomized to either having in-out catheterization or placement of an indwelling catheter for 24 h after surgery. A total of 1448 patients was recruited. The overall incidence of urinary retention was 4.1% (n = 60). Significant risk factors associated with postoperative urinary retention included old age, anorectal procedures and use of spinal anaesthesia. Comparison of re-catheterization and urinary tract infection rates between patients who were treated with in-out versus overnight catheterization found no significant differences. Postoperative urinary retention should be managed by in-out catheterization. Indwelling catheterization for 24 h appeared to bestow no additional benefits. The incidence of urinary retention increases with age, anorectal procedures and the use of spinal anaesthesia.

Postpartum bladder rupture is an uncommon surgical emergency and a diagnostic challenge. A primigravida delivered a healthy newborn without complications at 39.4 weeks of gestation. The patient was admitted 80 hours postpartum with abdominal pain, oliguria, hematuria, and pain that worsened during the previous 4 hours. An inserted Foley catheter drained only a small amount of urine, and serum creatinine was elevated (3.5 mg/dL). A laparotomy was performed and revealed a 10-cm hole in the urinary bladder. The bladder was repaired and the patient was discharged 15 days after surgery. The follow-up cystoscopy revealed adequate healing of the bladder. Urinary retention can lead to serious complications, including bladder rupture. Postpartum bladder rupture due to urinary retention should be ruled out if there is a history of abdominal pain, oliguria, and elevated of serum creatinine.

We present a prospective randomized study to compare the efficacy of tamsulosin and silodosin in patients suffering from acute urinary retention caused by benign prostatic hyperplasia, planned for trial without catheter. Patients with acute urinary retention secondary to benign prostatic hyperplasia (total 160) were catheterized and randomized into two groups: Group A: tamsulosin 0.4 mg (80 patients) and Group B: silodosin 8 mg (80 patients). After three days, the catheter was removed, and patients were put on trial without catheter. Patients with a successful trial without catheter were followed up after two weeks and one month, taking into account the international prostate symptom score (IPSS), post void residual volume (PVR), and peak flow rate (PFR). Statistical analysis of the data was performed. Both group A (tamsulosin) and group B (silodosin) had similar results of trial without catheter (group A: 67.50%, group: B 60%). In follow up, three patients in group A and four patients in group B had retention of urine, requiring recatheterization. These patients were withdrawn from the study. No significant differences were present between group A and group B patients in regard with IPSS, PVR and PFR measured at the time of successful trial without catheter and during follow up at two weeks and one month. Efficacy for trial without catheter of tamsulosin was slightly higher than silodosin, but comparable. No statistical difference between tamsulosin & silodosin treated groups were found in regard with IPSS, PVR and PFR.

To determine if postoperative urinary retention and urinary tract infections (UTIs) were predictors of future mesh complications requiring surgical intervention after midurethral sling (MUS). Administrative data in Ontario, Canada, between 2002 and 2013 were used to identify all women who underwent a mesh-based MUS. The primary outcome was revision of the transvaginal mesh sling (including mesh removal/erosion/fistula, or urethrolysis). Two potential risk factors were analyzed: postoperative retention (within 30 days of procedure) and number of postoperative emergency room visits or hospital admissions for UTI symptoms. A total of 59,556 women had a MUS, of which 1598 (2.7%) required revision surgery. Of the 2025 women who presented to the emergency room or were admitted to hospital for postoperative retention, 212 (10.5%) required operative mesh revision. Of the 11,747 patients who had at least one postoperative UTI, 366 (3.1%) patients required operative mesh revision. In adjusted analysis, postoperative retention was significantly predictive of future reoperation (hazard ratio [HR] 3.46, 95% confidence interval [CI] 2.97-4.02), and this difference persisted when urethrolysis was excluded as a reason for sling revision (HR 3.08, 95% CI 2.62-3.63). Similarly, in adjusted analysis, each additional postoperative hospital visit for UTI symptoms increased the risk for surgical intervention for mesh complications (HR 1.74, 95% CI 1.61-1.87). Postoperative urinary retention and hospital presentation for UTI symptoms are associated with an increased risk of reoperation for MUS complications. These patients should be followed and investigated for mesh complications when appropriate. Copyright © 2016 Elsevier Inc. All rights reserved.

Sacral Nerve Stimulation For Urinary Urge Incontinence, Urgency-Frequency, Urinary Retention, and Fecal Incontinence

Science.gov (United States)

2005-01-01

Executive Summary Objective The aim of this review was to assess the effectiveness, safety, and cost of sacral nerve stimulation (SNS) to treat urinary urge incontinence, urgency-frequency, urinary retention, and fecal incontinence. Background: Condition and Target Population Urinary urge incontinence, urgency-frequency, urinary retention, and fecal incontinence are prevalent, yet rarely discussed, conditions. They are rarely discussed because patients may be uncomfortable disclosing their symptoms to a health professional or may be unaware that there are treatment options for these conditions. Briefly, urge incontinence is an involuntary loss of urine upon a sudden urge. Urgency-frequency is an uncontrollable urge to void, which results in frequent, small-volume voids. People with urgency-frequency may or may not also experience chronic pelvic pain. Urinary retention refers to the inability to void despite having the urge to void. It can be caused by a hypocontractile detrusor (weak or no bladder muscle contraction) or obstruction due to urethral overactivity. Fecal incontinence is a loss of voluntary bowel control. The prevalence of urge incontinence, urgency-frequency, and urinary retention in the general population is 3.3% to 8.2%, and the prevalence of fecal incontinence is 1.4% to 1.9%. About three-quarters of these people will be successfully treated by behaviour and/or drug therapy. For those who do not respond to these therapies, the options for treatment are management with diapers or pads, or surgery. The surgical procedures are generally quite invasive, permanent, and are associated with complications. Pads and/or diapers are used throughout the course of treatment as different therapies are tried. Patients who respond successfully to treatment may still require pads or diapers, but to a lesser extent. The Technology Being Reviewed: Sacral Nerve Stimulation Sacral nerve stimulation is a procedure where a small device attached to an electrode is

The urinary bladder diverticula (BD) secondary to benign prostatic hyperplasia (BPH) is a complication that can lead to urinary stasis, stone, urinary tract infection (UTI) and tumors. It's role in acute urinary retention (AUR) is not totally understood. To determine the effect of BD size on AUR rates in patients with BPH candidates to surgery. We performed a retrospective cohort study of 47 patients with BPH and BD who underwent BPH surgery associated to complete bladder diverticulectomy from 2006 to 2016. We analyzed risk factors for AUR in patients with BD using univariate, multivariate and correlation analysis. There was a difference in the size of the diverticula, with 6.8 cm vs. 4.5 cm among patients with and without AUR respectively (p=0.005). The ROC curve showed a correlation between the size of BD and the risk of AUR. The value of 5.15 cm presented a sensitivity of 73% and a specificity of 72%. The area under the curve was 0.75 (p=0.01). Comparing groups with BD >5.0 cm vs. ≤5.0 cm, the AUR incidence was 74% and 27.8% respectively with an OR of 2.65 (1.20-5.85) (p=0.005). In the multivariate analysis, only the size of the diverticula reached statistical significance (p=0.012). The diameter of BD is an independent risk factor for AUR in patients with BPH and BD who are candidates to surgery. A diameter greater than 5.15 cm increases the risk of AUR.

Urinary retention is a common complication of pelvic surgery, leading to urinary tract infection and prolonged hospital stays. Tamsulosin is an alpha blocker that works by relaxing bladder neck muscles. It is used to treat benign prostatic hypertrophy and retention. We aim to investigate the potential benefits of preemptive tamsulosin use on rates of urinary retention in men undergoing pelvic surgery. This is a retrospective review of an institutional colorectal database. All men undergoing pelvic surgery between 2004 and 2013 were included. Patients given 0.4 mg of tamsulosin 3 days prior and after surgery at discretion of surgeon starting in 2007 were compared with patients receiving expectant postoperative management. One hundred eighty-five patients were included in the study (study group: N = 30; control group: N = 155). Study group patients were older (56.8 vs. 50.1 years). Overall urinary retention rate was 22% with significantly lower rates in the study group compared with control (6.7 vs. 25%; p = 0.029). Study group had higher rates of minimally invasive surgery (61 vs. 29.7%); however, this did not impact urinary retention rate (20.6 vs. 22.7% for minimally invasive surgery vs. open surgery; p = 0.85). Independent predictors of urinary retention included lack of preemptive tamsulosin (odds ratio (OR), 7.67; 95% confidence interval (CI), 1.4-41.7) and cancer location in the distal third of the rectum (OR, 18.8; 95% CI, 2.1-172.8). Preemptive perioperative use of tamsulosin may significantly decrease the incidence of urinary retention in men undergoing pelvic surgery. This may play a role in avoidance of urinary retention, particularly in patients with distal rectal cancer.

A 70-year-old man developed urinary retention in the early stages of herpes simplex virus (HSV) type-1 encephalitis. A nerve conduction study suggested latent myeloradiculitis. This is the first report of human herpes simplex virus-1 encephalitis followed by urinary retention at early stage from the onset like the Elsberg syndrome. Although relatively few similar cases have been reported, we consider that urinary retention is common in HSV-1 encephalitis, in which disturbances of consciousness usually require bladder catheterization from the onset. We further emphasize that urinary retention may occasionally occur in early stages of HSV-1 encephalitis, with a significant possibility of recovery. Copyright © 2017. Published by Elsevier B.V.

Sacral root neuromodulation in idiopathic nonobstructive chronic urinary retention.

Science.gov (United States)

Shaker, H S; Hassouna, M

1998-05-01

Sacral root neuromodulation is becoming a superior alternative to the standard treatment of idiopathic nonobstructive urinary retention. We report results in 20 successive patients who underwent sacral foramen implantation to restore bladder function. After an initial, thorough baseline assessment 20 patients 19.43 to 55.66 years old with idiopathic nonobstructive urinary retention underwent percutaneous nerve evaluation. Response was assessed by a detailed voiding diary. Responders underwent implantation with an S3 foramen implant, and were followed 1, 3 and 6 months postoperatively, and every 6 months thereafter. Sacral root neuromodulation restored voiding capability in these patients. Bladders were emptied with minimal post-void residual urine, which decreased from 78.3 to 5.5 to 10.2% of the total voided volume from baseline to postoperative followup. These results were reflected in uroflowmetry and pressure-flow studies, which were almost normal after implantation. Furthermore, the urinary tract infection rate decreased significantly and associated pelvic pain improved substantially. The Beck depression inventory and SF-36 quality of life questionnaire indicated some improvement but reached significance in only 1 item. In addition, cystometrography showed no significant difference after 6 months of implantation compared with baseline values. Complications were minimal and within expectations. Sacral root neuromodulation is an appealing, successful modality for nonobstructive urinary retention. Only patients who have a good response to percutaneous nerve evaluation are candidates for implantation. The high efficacy in patients who undergo implantation, relative simplicity of the procedure and low complication rate make this a treatment breakthrough in this difficult group.

Urinary retention is one of the most common complications contributing to surgical procedures. Recent studies have shown the benefits of alpha-adrenergic blockers in preventing post-operative urinary retention (POUR). The aim of this prospective study was to compare the prophylactic effect of tamsulosin with placebo on postoperative urinary retention. In this randomized placebo controlled, clinical trial, 232 male patients aged 18 to 50 years old admitted to Razi University Hospital for varicocelectomy, inguinal herniorrhaphy, and scrotal surgery were randomly assigned to receive either three doses of 0.4mg tamsulosin (n = 118) or placebo (n = 114), 14 and 2 hours before, and 10 hours after surgery. Patients were closely monitored for the development of urinary retention 24 hours after surgical intervention. The primary endpoint was to investigate the effect of tamsulosin in prevention of post-operative urinary retention during the first 24 hours after surgical intervention. Collected data were analyzed using SPSS software version 18 and the P tamsulosin arm and 114 in placebo arm. POUR in patients who received tamsulosin was significantly lower than placebo, as 5.9% of the patients treated with tamsulosin and 21.1% placebo group, reported urinary retention following surgery (P = 0.001). No serious adverse effects were seen in both groups. This study suggests that short perioperative treatment with tamsulosin can reduce the incidence of urinary retention and the need for catheterization after varicocelectomy, inguinal herniorrhaphy, and scrotal surgery.

Purpose: Urinary retention requiring catheterization is a known complication among prostate cancer patients treated with permanent interstitial radioactive seed implantation. However, the factors associated with this complication are not well known. This study was conducted to determine these factors. Methods and Materials: Ninety-one consecutive prostate cancer patients treated with permanent interstitial implantation at our institution from 1996 to 1999 were evaluated. All patients underwent pre-implant ultrasound and postimplant CT volume studies. Isotopes used were 125 I (54 patients) or 103 Pd (37 patients). Twenty-three patients were treated with a combination of 45 Gy of external beam radiation therapy as well as seed implantation, of which only 3 patients were treated with 125 I. Mean pretreatment prostate ultrasound volume was 35.4 cc (range, 10.0-70.2 cc). The mean planning ultrasound target volume (PUTV) was 39.6 cc (range, 16.1-74.5 cc), whereas the mean posttreatment CT target volume was 55.0 cc (range, 20.2-116 cc). Patient records were reviewed to determine which patients required urinary catheterization for relief of urinary obstruction. The following factors were analyzed as predictors for urinary retention: clinical stage; Gleason score; prostate-specific antigen; external beam radiation therapy; hormone therapy; pre-implant urinary symptoms (asymptomatic/nocturia x 1 vs. more significant urinary symptoms); pretreatment ultrasound prostate volume; PUTV; PUTV within the 125%, 150%, 200%, 250%, 300% isodose lines; postimplant CT volume within the 125%, 150%, 200%, 250%, 300% isodose lines; D90; D80; D50; ratio of post-CT volume to the PUTV; the absolute change in volume between the CT volume and PUTV; number of needles used; activity per seed; and the total activity of the implant. Statistical analyses using logistic regression and χ2 were performed. Results: Eleven of 91 (12%) became obstructed. Significant factors predicting for urinary retention

Haanpää, Maija; Paavonen, Jorma

Genital herpes (GH) causes genital ulcer disease, severe transient pain, and often paresthesias. Whether or not GH can cause urinary retention or chronic neuropathic pain is not well known. We present two immunocompetent patients with GH associated with neuropathic symptoms. We also review the literature on GH and associated neurologic problems. Patient 1 had primary herpes simplex virus (HSV)-2 infection with transient urinary retention and chronic bilateral neuropathic pain in the sacral area. Patient 2 had recurrent HSV-1 associated with unitaleral chronic neuropathic pain in the sacral area. Although transient urinary retention associated with GH is not uncommon, chronic neuropathic pain has not been reported previously. Our cases show that chronic neuropathic pain, that is "pain initiated or caused by a primary lesion or dysfunction in the nervous system," can follow genital HSV infection.

Urinary retention in women often presents a diagnostic difficulty, and the etiology may remain unidentified even after excluding structural and neurological causes. We evaluated a group of women referred to a specialist center with unexplained urinary retention. A total of 61 consecutive women with complete urinary retention were evaluated. Urological and neurological investigations locally had failed to identify a cause. Urethral pressure profile, sphincter volume measurement and in some cases urethral sphincter electromyography were performed to diagnose a primary disorder of sphincter relaxation (Fowler's syndrome). Mean patient age was 39 years (range 18 to 88). Following investigations, a probable etiology was identified in 25 (41%) women, the most common being Fowler's syndrome. Of the women 24 (39%) were being treated with opiates for various pain syndromes and in 13 no other cause of retention was identified. Opiates could be discontinued in only 2 patients, and both demonstrated improved sensations and voiding. The cause of urinary retention may remain unknown in spite of extensive investigations. Young women regularly using prescription opiates for various undiagnosed pain syndromes present a challenging clinical problem and this study suggests that iatrogenic causes should be considered if voiding difficulties emerge. An association between opiate use and constipation is well-known and, although urinary retention is a listed adverse event, it appears to be often overlooked in clinical practice. It is hypothesized that Fowler's syndrome is due to an up-regulation of spinal cord enkephalins and that exogenous opiates may compound any functional abnormalities predisposing young women to urinary retention.

To compare the frequency of urinary retention and requirement of bladder catheterization in patients undergoing toatal knee arthroplasty while receiving either continuous epidural analgesia or single-shot femoral nerve block. Study Design: Randomized controlled study. Place and Duration of Study:Operating Rooms of Aga Khan University Hospital, Karachi, from January 2014 to January 2015. Methodology:Patients were randomized in two groups of 30 each, i.e. epidural group (group E) or femoral nerve block group (group F). Baseline parameters were recorded. Postoperatively, patients were followed for upto 24 hours to collect the data regarding urinary retention. Final outcome was taken at 24 hours postoperatively. Data was analyzed to compare the frequency of urinary retention between the two groups. Results:The average age of the patients was 59.58 +-5.85 years. There were 28 (46.7%) male and 32 (53.3%) female patients. Frequency of urinary retention was significantly high in Group E than Group F (46.7% vs. 6.7%; p=0.0005). Conclusion: Single-shot femoral nerve block offers a more favorable profile in terms of postoperative urinary retention when compared to continuous epidural analgesia. (author)

Prevention and management of postoperative urinary retention after urogynecologic surgery

Full Text Available Elizabeth J Geller Division of Female Pelvic Medicine and Reconstructive Surgery, Department of Obstetrics and Gynecology, University of North Carolina at Chapel Hill, Chapel Hill, NC, USA Abstract: Postoperative urinary retention (POUR is a frequent consequence of gynecologic surgery, especially with surgical correction of urinary incontinence and pelvic organ prolapse. Estimates of retention rates after pelvic surgery range from 2.5%–43%. While there is no standard definition for POUR, it is characterized by impaired bladder emptying, with an elevation in the volume of retained urine. The key to management of POUR is early identification. All patients undergoing pelvic surgery, especially for the correction of incontinence or prolapse, should have an assessment of voiding function prior to discharge. There are several ways to assess voiding function – the gold standard is by measuring a postvoid residual. Management of POUR is fairly straightforward. The goal is to decompress the bladder to avoid long-term damage to bladder integrity and function. The decision regarding when to discontinue catheter-assisted bladder drainage in the postoperative period can be assessed in an ongoing fashion by measurement of postvoid residual. The rate of prolonged POUR beyond 4 weeks is low, and therefore most retention can be expected to resolve spontaneously within 4–6 weeks. When POUR does not resolve spontaneously, more active management may be required. Techniques include urethral dilation, sling stretching, sling incision, partial sling resection, and urethrolysis. While some risk of POUR is inevitable, there are risk factors that are modifiable. Patients that are at higher risk – either due to the procedures being performed or their clinical risk factors – should be counseled regarding the risks and management options for POUR prior to their surgery. Although POUR is a serious condition that can have serious consequences if left untreated, it

Purpose: To risk-stratify patients for urinary retention after prostate brachytherapy according to a novel seed implant retention score (SIRS). Patients and Methods: A total of 835 patients underwent transperineal prostate seed implant from March 1993 to January 2007; 197 patients had 125 I and 638 patients had 103 Pd brachytherapy. Four hundred ninety-four patients had supplemental external-beam radiation. The final downsized prostate volume was used for the 424 patients who had neoadjuvant hormone therapy. Retention was defined as reinsertion of a Foley catheter after the implant. Results: Retention developed in 7.4% of patients, with an average duration of 6.7 weeks. On univariate analysis, implant without supplemental external-beam radiation (10% vs. 5.6%; p = 0.02), neoadjuvant hormone therapy (9.4% vs. 5.4%; p = 0.02), baseline α-blocker use (12.5% vs. 6.3%; p = 0.008), and increased prostate volume (13.4% vs. 6.9% vs. 2.9%, >45 cm 3 , 25-45 cm 3 , 3 ; p = 0.0008) were significantly correlated with increased rates of retention. On multivariate analysis, implant without supplemental external-beam radiation, neoadjuvant hormone therapy, baseline α-blocker use, and increased prostate volume were correlated with retention. A novel SIRS was modeled as the combined score of these factors, ranging from 0 to 5. There was a significant correlation between the SIRS and retention (p < 0.0001). The rates of retention were 0, 4%, 5.6%, 9%, 20.9%, and 36.4% for SIRS of 0 to 5, respectively. Conclusions: The SIRS may identify patients who are at high risk for prolonged retention after prostate brachytherapy. A prospective validation study of the SIRS is planned.

Full Text Available Background/Aims. Aim of the study was to establish an effect of obesity on the incidence of bladder injury or urinary retention following tension-free vaginal tape (TVT procedure. Methods. This was a retrospective cohort study based at the Norfolk and Norwich University Hospital in the UK. Study population included 342 cases of TVT procedures. Incidence of bladder injury was 4.7% (16/342. Rate of urinary retention was 9% (31/342. Body mass index (BMI, age, type of analgesia, concomitant prolapse repair, and previous surgery were factors studied. Univariate analysis was performed to establish a relationship between BMI and complications, followed by a multivariable regression analysis to adjust for age, concomitant surgery, type of analgesia, and previous surgery. Results. Neither univariate analysis nor multivariate regression analysis revealed any statistically significant influence of obesity on the incidence of bladder injury or urinary retention. Unadjusted odds ratios and adjusted odds ratios for bladder injury and urinary retention by BMI groups were OR 1.7296 CI 0.4818–6.2097; OR 1.3745 CI 0.5718–3.3043 and adj. OR 2.885 CI 0.603–13.8; adj. OR 1.299 CI 0.502–3.365. Conclusion. Obesity does not appear to influence the rate of bladder injury or urinary retention following TVT procedure.

Full Text Available Abstract Objectives To understand the clinical relationship between lower limbs functions and the recovery of spontaneous voiding after an acute urinary retention (AUR in older patients admitted to hospitals for non-urological causes using clinical parameters. Materials and Methods 56 adult patients (32 men; mean age: 77.9 ± 8.3 and 24 women; mean age 82.1 ± 4.6 with AUR were prospectively followed with validated Physical Performance Mobility Exam (PPME instrument to evaluate the relationship between the recovery of mobility capacity and spontaneous voiding. After a short period of permanent bladder drainage patients started CIC along evaluation by PPME during hospitalization and at 7, 15, 30 60, 90, and 180 days of discharge. Mann-Whitney U, chi-square test and ANOVA tests were used. Results All patients were hospitalized for at least 15 days (Median 26.3 ± 4.1 days. Progressive improvement on mobility scale measured by PPME was observed after leaving ICU and along the initial 7 days of hospitalization but with a deterioration if hospitalization extends beyond 15 days (p<0.03. Prolonged hospital stay impairs mobility in all domains (p<0.05 except step-up and transfer skills (p<0.02 although a recovery rate on spontaneous voiding persistented. Restoration of spontaneous voiding was accompanied by improvement on mobility scale (p<0.02. Recovery of spontaneous voiding was markedly observed after discharging the hospital. All patients recovered spontaneous voiding until 6 months of follow-up. Conclusions Recovery to spontaneous voiding after acute urinary retention in the hospital setting may be anticipated by evaluation of lower limbs function measured by validated instruments.

Urinary tract infection is one of the most common bacterial infections encountered by pediatricians. Currently, the diagnosis and management of acute urinary tract infection and recurrent urinary tract infection in children remains controversial. Recently published guidelines and large clinical trials have attempted to clarify UTI diagnostic and management strategies. In this manuscript, we review the diagnosis and management of acute and recurrent urinary tract infection in the pediatric population. PMID:25421102

Sacral foramen neuromodulation--initially applied for the treatment of urinary incontinence--has proved to be effective in patients with chronic urinary retention. Thus far, the underlying neurophysiological mechanisms have not been elucidated. In an experimental study on the neurophysiological basis of sacral neurostimulation, one objective was to investigate the mechanisms responsible for initiation of micturition in chronic urinary retention. In ten female cats anesthetized with alpha-chloralose the clinical situation of sacral foramen stimulation was experimentally reproduced by isolated S2 nerve stimulation after L6-S3 laminectomy. Stimulation responses were recorded from the bladder, peripheral nerves, and striated muscles of the foot and pelvic floor. The effect of sudden cessation of prolonged S2 stimulation, during which the bladder was completely inhibited, was evaluated in 70 stimulation sequences in 5 cats. Sacral nerve stimulation induced excitatory and inhibitory effects on the bladder, depending on the frequency and intensity of stimulation. With unilateral S2 stimulation, bladder excitation was best at frequencies of 2-5 Hz and at intensities ranging between 0.8 and 1.4 times the threshold for the M-response of the foot muscle. Inhibition was the dominating effect at frequencies of 7-10 Hz and at intensities exceeding 1.4 times the threshold. Prolonged S2 stimulation above the threshold produced complete bladder inhibition during stimulation but induced strong bladder contractions after sudden interruption of stimulation, with amplitudes being significantly higher than that of spontaneous contractions preceding the stimulation. These results confirm the hypothesis of a "rebound" phenomenon as the mechanism of action for induction of spontaneous voiding in patients with chronic urinary retention.

The neurophysiology of urinary retention in young women and its treatment by neuromodulation.

Goodwin, R J; Swinn, M J; Fowler, C J

1998-01-01

Urinary retention occurring in young women as an isolated phenomenon was often thought to be psychogenic in origin. However, in 1988, Fowler et al. described a syndrome in young women in which urinary retention was the predominant feature and in which electromyography (EMG) of the striated urethral sphincter revealed a striking abnormality. This abnormality, it was postulated, would result in an inability of the sphincter to relax and retention would therefore result. Until recently there was no effective treatment for this disorder except management by clean intermittent self-catheterisation. However, preliminary results of neuromodulation using a Medtronic sacral nerve stimulator have been particularly promising in this group of patients. The response is often spectacular; a woman who has not passed urine per urethram for many months or years will frequently find that within a few hours of insertion of the percutaneous nerve evaluation (PNE) lead, she can void quite normally with little or no residual urine. The precise mechanism of action is yet to be defined, but measurements of the latency of anal sphincter contraction on S3 stimulation during PNE are so prolonged that they can only be the result of an afferent-mediated reflex.

PurposeThis study was designed to describe the clinical, laboratorial, and urodynamic findings of prostatic artery embolization (PAE) in patients with urinary retention due to benign prostatic hyperplasia (BPH).MethodsA prospective study of 11 patients with urinary retention due to BPH was conducted. Patients underwent physical examination, prostate specific antigen (PSA) measurement, transrectal ultrasound, and magnetic resonance imaging. International prostate symptom score (IPSS), quality of life (QoL), and urodynamic testing were used to assess the outcome before and after 1 year.ResultsClinical success was 91 % (10/11 patients) with a mean follow-up of 22.3 months (range, 12–41 months). At the first year follow-up, the mean IPSS score was 2.8 points (p = 0.04), mean QoL was 0.4 points (p = 0.001), mean PSA decreased from 10.1 to 4.3 ng/mL (p = 0.003), maximum urinary flow (Qmax) improved from 4.2 to 10.8 mL/sec (p = 0.009), and detrusor pressure (Pdet) decreased from 85.7 to 51.5 cm H 2 O (p = 0.007). Before PAE, Bladder Outlet Obstruction Index (BOOI) showed values >40 in 100 % of patients. After PAE, 30 % of patients were >40 (obstructed), 40 % were between 20 and 40 (undetermined), and 30 % were <20 (unobstructed). Patients with a BOOI <20 had higher PSA values at 1-day after PAE.ConclusionsClinical and urodynamic parameters improved significantly after PAE in patients with acute urinary retention due to BPH. Total PSA at day 1 after PAE was higher in patients with unobstructed values in pressure flow studies

2003-01-01

A case of sacral herpes zoster infection in a 56-year-old man with the complication of loss of urinary voiding sensation is presented. He had typical herpes zoster eruption on the left S2 dermatome, hypalgesia of the S1-S4 dermatomes, and absence of urinary voiding sensation. There was no other urinary symptom at the first medical examination. Urinary complications associated with herpes zoster are uncommon, but two types, acute cystitis and acute retention, have been recognized. No cases of loss of urinary voiding sensation due to herpes zoster have been reported. In this case, hypalgesia of the sacral dermatomes was mild compared to the marked loss of urethral sensation. This inconsistency is explained by the hypothesis that the number of urethral fibers is very small as compared to that of cutaneous fibers, therefore, urethral sensation would be more severely disturbed than cutaneous sensation.

Nay M Htun

Full Text Available Identification of individuals who are at risk of suffering from acute coronary syndromes (ACS may allow to introduce preventative measures. We aimed to identify ACS-related urinary peptides, that combined as a pattern can be used as prognostic biomarker. Proteomic data of 252 individuals enrolled in four prospective studies from Australia, Europe and North America were analyzed. 126 of these had suffered from ACS within a period of up to 5 years post urine sampling (cases. Proteomic analysis of 84 cases and 84 matched controls resulted in the discovery of 75 ACS-related urinary peptides. Combining these to a peptide pattern, we established a prognostic biomarker named Acute Coronary Syndrome Predictor 75 (ACSP75. ACSP75 demonstrated reasonable prognostic discrimination (c-statistic = 0.664, which was similar to Framingham risk scoring (c-statistics = 0.644 in a validation cohort of 42 cases and 42 controls. However, generating by a composite algorithm named Acute Coronary Syndrome Composite Predictor (ACSCP, combining the biomarker pattern ACSP75 with the previously established urinary proteomic biomarker CAD238 characterizing coronary artery disease as the underlying aetiology, and age as a risk factor, further improved discrimination (c-statistic = 0.751 resulting in an added prognostic value over Framingham risk scoring expressed by an integrated discrimination improvement of 0.273 ± 0.048 (P < 0.0001 and net reclassification improvement of 0.405 ± 0.113 (P = 0.0007. In conclusion, we demonstrate that urinary peptide biomarkers have the potential to predict future ACS events in asymptomatic patients. Further large scale studies are warranted to determine the role of urinary biomarkers in clinical practice.

This study protocol evaluates the effectiveness of adjuvant electroacupuncture (EA) for urinary retention in poststroke patients undergoing conventional treatments, in comparison with that of a sham control. A multicenter, blinded, randomized controlled trial will be conducted in three hospitals in the Republic of Korea. We are recruiting 54 stroke survivors (aged >19 years), who were diagnosed with urinary retention based on the results of two consecutive post-void residual (PVR) tests, and dividing them randomly into two arms: the EA and Park-sham control groups. They will receive ten sessions of EA or sham treatment for 2 weeks. The participants will be blinded with non-penetrating needles and fake sounds of EA stimulators. The daily PVR ratio will be primarily measured at baseline and at the end of the study to statistically test the effectiveness of EA for poststroke urinary retention. Then, the Korean version of the Qualiveen Questionnaire, the Korean version of the International Prostate Symptom Score, and the blinding index will be assessed. After each EA session or sham EA, adverse events will be reported to evaluate the safety of EA. Results will be analyzed by using the independent t-test or Mann-Whitney U test, based on both intention-to-treat and per-protocol principles. The findings will provide clinical evidence for the effectiveness of EA treatment to improve urinary retention in stroke survivors. This study protocol was registered in ClinicalTrials.gov (NCT02472288) on 10 June 2015.

2009-01-01

Urological expertise is usually required for the management of any urological complications of bladder-drained pancreatic allografts whether they are the result of simultaneous pancreas-kidney transplants, pancreas after kidney transplants, or pancreas transplants alone. This study presents a case of urinary retention secondary to prostatic urethra calculus impaction, the nidus of which was found to be metallic staples from the donor duodenal segment of a pancreatic allograft. Knowledge of the pre-transplant benchwork gave a high index of suspicion to the urological sequelae of this case and, in particular, the presence of calculi should suggest a metal clip nidus. We examine the methods of exocrine pancreatic drainage, donor duodenum preparation and case management.

Neurogenic inflammation is linked to urinary bladder overactivity development. Cyclophosphamide (CYP) damages all mucosal defence lines of urinary bladder and induces cystitis with overactivity. The aim of this study was to estimate the effect of CYP on rat urinary bladder function, histological structure and mastocytes numbers following acute and chronic CYP treatment. Fourty two female rats were divided into four groups: I (control), II (acute cystitis), III (chronic cystitis), IV (sham group). Acute and chronic cystitis were induced by CYP in single dose and four doses (1(st), 3(rd), 5(th), 7(th) day), respectively. In group I-III the cystometric evaluation was performed. Sections of the bladder were stained with HE and toluidine blue for the detection of mastocytes. The severity of inflammation was examined according to mucosal abrasion, haemorrhage, leukocyte infiltration and oedema. Acute and chronic CYP treatment caused inflammatory macroscopic and microscopic changes (mucosal abrasion, haemorrhage, oedema) and increased infiltration of inflammatory cells in urinary bladder. Acute treatment induced the infiltration of mastocytes within bladder wall contrary to chronic one decrement. Acute treatment caused more severe mucosal abrasion, whereas chronic one revealed more developed haemorrhage changes. Additionally, cystometric evaluation revealed urinary bladder overactivity development in both types of cystitis. Basal pressure and detrusor overactivity index after acute treatment increased considerably in comparison with the increase obtained after chronic one. Our results proved that acute model of CYP-induced cystitis in rats is more credible for further evaluation of neurogenic inflammation response in pathogenesis of overactive bladder as compared to chronic one.

Postoperative urinary retention (POUR) is one of the most common complications after surgical procedures under spinal anaesthesia. Recent studies have shown the beneficial effects of alpha-adrenergic blockers in preventing POUR. The aim of this prospective study was to investigate and compare the prophylactic effects of tamsulosin and alfuzosin on POUR after urologic surgical procedures under spinal anaesthesia. A total of 180 males who underwent elective urologic surgery were included in this study. The patients were randomly allocated into three Groups. The Group I received placebo. Patients in Group II were given 0.4mg of tamsulosin orally 14 and 2 hours before surgery. Patients in Group III were given 10mg of alfuzosin ER orally 10 and 2 hours before surgery. All patients were closely followed for 24 hours postoperatively and their episodes of urinary retentions were recorded. There were 60 patients in each Group. Their mean age was 35.95±15.16 years. Fifteen patients in Group I (25%), 3 patients in Group II (5%) and 4 patients in Group III (6.7%) required catheterization because of urinary retention. In tamsulosin group and alfuzosin group, there were a significantly lower proportion of patients with POUR compared with the placebo Group (p=0.002 and p=0.006). The beneficial effects of tamsulosin and alfuzosin on POUR were similar between both Groups (p=0.697). This study suggests that the use of prophylactic tamsulosin or alfuzosin can reduce the incidence of urinary retention and the need for catheterization after urologic surgical procedures under spinal anaesthesia.

An 87-year-old woman presents with a 4-week history of urinary incontinence during which she had been treated for disseminated herpes zoster virus (HZV). On physical exam painful vesicles involving the entire vulvar region with mainly right sacral distribution were found. A catheterized volume exceeded 600 ml of retained urine after the patient failed to void spontaneously. Multichannel voiding-pressure urodynamic studies revealed an acontractile neurogenic bladder with overflow incontinence. The patient was discharged on a conservative regimen with arrangement for visiting nurse services to perform intermittent self-catheterization twice daily. Urodynamic testing was repeated 10 weeks after initial symptoms. During voiding cystometry a biphasic increase in detrusor pressure of 15 cm H2O was observed with no increase in abdominal pressure. The patient emptied 400 ml with a postvoid residual of 300 ml. Recovery from HZV-associated bladder emptying dysfunction can be achieved usually through conservative management, including intermittent self-catheterization. Complete recovery time ranges from 4 to 10 weeks.

Pathogenesis of acute radiation effects in the urinary bladder. Experimental results

International Nuclear Information System (INIS)

Doerr, W.; Eckhardt, M.; Ehme, A.; Koi, S.

1998-01-01

Purpose: The present review summarizes experimental studies of the pathogenesis of acute radiation-induced changes in urinary bladder function. Material and methods: Transurethral cystometry was used for longitudinal assessment of bladder function in mice. With this technique, radiation-induced changes in storage capacity can be quantified. In histological studies, changes in urothelial cell density and in urothelial protein expression during the acute radiation response were determined. Acetylsalicylic acid (ASA) was used for the treatment of acute functional changes. Results: The histological studies did not reveal any systematic fluctuations in urothelial cell density during the time of the acute radiation response. However, characteristic changes in the expression of proteins associated with urothelial cell function, differentiation and cell contact were observed, which correlated with the functional impairment. By local or systemical application of ASA, a significant restoration of bladder function compared to placebo treatment could be achieved. Conclusion: Acute functional radiation effects in the urinary bladder are not based on urothelial denudation. However, changes in protein expression indicate an impairment of the urothelial barrier function. The results of ASA treatment demonstrate that prostaglandins are involved in the response. Alterations in urothelial or endothelial prostaglandin metabolism may be primarily radiation-induced or secondary because of the impaired urothelial barrier. (orig.) [de

Bemelmans, B L; Mundy, A R; Craggs, M D

1999-08-01

Patients with irritative micturition complaints, pelvic pain, involuntary urine loss or urinary retention are sometimes difficult to treat. The advent of direct sacral nerve stimulation offers a therapeutic alternative if conservative measures fail and surgery is considered. This paper reviews therapeutic neuromodulation by implant for treating lower urinary tract symptoms and dysfunction. The international literature is reviewed on topics such as the physiological basis of neuromodulation, techniques of acute testing and chronic implantation, and clinical results. Future developments and ways for possible improvement are discussed. The mode of action of neuromodulation is probably through restoring the correct balance between excitatory and inhibitory impulses from and to the pelvic organs at a sacral and supra-sacral level. Depending on the predefined success criteria, average success rates of definitive implants vary from 50 to 70%. From the data it seems that patients with urge incontinence and urinary retention are the best candidates for neuromodulation. In the literature the lack of standardisation of selection criteria, stimulation parameters and definitions of success is striking. Neuromodulation by implant is a useful therapeutic alternative. It should at least be considered in patients with therapy-resistant urge incontinence and urinary retention before proceeding to surgery. Issues such as underlying physiology, methodological standardisation, technical improvements, and patient selection must be addressed in future research.

Acute upper urinary tract infection may cause sepsis, especially in neonates and infants, mandating the choice of appropriate, effective antibacterials minimizing increasing bacterial resistance. Frequently prescribing broad-spectrum cephalosporinin is one such example. Different antibacterial therapies are initiated clinically due to treatment protocol differences among institutions, disease severity, etc. We studied the efficacy of cefazolin (CEZ), a first-generation cephalosporin, as first-line parenteral treatment in acute upper urinary tract infection.

Full Text Available ABSTRACT Purpose Postoperative urinary retention (POUR is one of the most common complications after surgical procedures under spinal anaesthesia. Recent studies have shown the beneficial effects of alpha-adrenergic blockers in preventing POUR. The aim of this prospective study was to investigate and compare the prophylactic effects of tamsulosin and alfuzosin on POUR after urologic surgical procedures under spinal anaesthesia. Materials and Methods A total of 180 males who underwent elective urologic surgery were included in this study. The patients were randomly allocated into three Groups. The Group I received placebo. Patients in Group II were given 0.4mg of tamsulosin orally 14 and 2 hours before surgery. Patients in Group III were given 10mg of alfuzosin ER orally 10 and 2 hours before surgery. All patients were closely followed for 24 hours postoperatively and their episodes of urinary retentions were recorded. Results There were 60 patients in each Group. Their mean age was 35.95±15.16 years. Fifteen patients in Group I (25%, 3 patients in Group II (5% and 4 patients in Group III (6.7% required catheterization because of urinary retention. In tamsulosin group and alfuzosin group, there were a significantly lower proportion of patients with POUR compared with the placebo Group (p=0.002 and p=0.006. The beneficial effects of tamsulosin and alfuzosin on POUR were similar between both Groups (p=0.697. Conclusion This study suggests that the use of prophylactic tamsulosin or alfuzosin can reduce the incidence of urinary retention and the need for catheterization after urologic surgical procedures under spinal anaesthesia.

Robert G Hahn

Full Text Available Renal conservation (retention of fluid might affect the outcome of hospital care and can be indicated by increased urinary concentrations of metabolic waste products. We obtained a reference material for further studies by exploring the prevalence of fluid retention in a healthy population.Spot urine sampling was performed in 300 healthy hospital workers. A previously validated algorithm summarized the urine-specific gravity, osmolality, creatinine, and color to a fluid retention index (FRI, where 4.0 is the cut-off for fluid retention consistent with dehydration. In 50 of the volunteers, we also studied the relationships between FRI, plasma osmolality, and water-retaining hormones.The cut-off for fluid retention (FRI ≥ 4.0 was reached by 38% of the population. No correlation was found between the FRI and the time of the day of urine sample collection, and the FRI was only marginally correlated with the time period spent without fluid intake. Volunteers with fluid retention were younger, generally men, and more often had albuminuria (88% vs. 34%, P < 0.001. Plasma osmolality and plasma sodium were somewhat higher in those with a high FRI (mean 294.8 vs. 293.4 mosmol/kg and 140.3 vs. 139.9 mmol/l. Plasma vasopressin was consistently below the limit of detection, and the plasma cortisol, aldosterone, and renin concentrations were similar in subjects with a high or low FRI. The very highest FRI values (≥ 5.0, N = 61 were always accompanied by albuminuria.Fluid retention consistent with moderate dehydration is common in healthy staff working in a Swedish hospital.

The role of imaging in adult acute urinary tract infection

International Nuclear Information System (INIS)

Webb, J.A.W.

1997-01-01

Imaging is required in only a minority of patients with urinary tract infection. Some patients who present with severe loin pain are imaged because ureteric colic is suspected. If urinary tract infection does not respond normally to antibiotics, imaging is undertaken to check for evidence of renal obstuction or sepsis. Finally, after the acute infection has been treated, imaging is required in some patients to check for factors pre-disposing to renal damage or to relapsing or recurrent infection. This review discusses the appropriate choice of imaging technique to use in each clinical situation and summarises the expected findings. (orig.). With 15 figs., 1 tab

The objectives of this study were to describe the frequency of and to determine predictive factors associated with Radiation Therapy Oncology Group urinary toxicity in prostate brachytherapy patients. From January 2004 to April 2011, 466 consecutive Japanese patients underwent permanent iodine-125-seed brachytherapy (median follow up 48 months). International Prostate Symptom Score and Radiation Therapy Oncology Group toxicity data were prospectively collected. Prostate volume, International Prostate Symptom Score before and after brachytherapy, and postimplant analysis were examined for an association with urinary toxicity, defined as Radiation Therapy Oncology Group urinary toxicity of Grade 1 or higher. Logistic regression analysis was used to examine the factors associated with urinary toxicity. The rate of Radiation Therapy Oncology Group urinary toxicity grade 1 or higher at 1, 6, 12, 24, 36 and 48 months was 67%, 40%, 21%, 31%, 27% and 28%, respectively. Grade 2 or higher urinary toxicity was less than 1% at each time-point. International Prostate Symptom Score was highest at 3 months and returned to normal 12 months after brachytherapy. On multivariate analysis, patients with a larger prostate size, greater baseline International Prostate Symptom Score, higher prostate V100, higher prostate V150, higher prostate D90 and a greater number of seeds had more acute urinary toxicities at 1 month and 12 months after brachytherapy. On multivariate analysis, significant predictors for urinary toxicity at 1 month and 12 months were a greater baseline International Prostate Symptom Score and prostate V100. Most urinary symptoms are tolerated and resolved within 12 months after prostate brachytherapy. Acute and late urinary toxicity after brachytherapy is strongly related to the baseline International Prostate Symptom Score and prostate V100. (author)

Full Text Available The aim of this study was to determine the subsequent risk of acute urine retention and prostate surgery in patients receiving alpha-1 blockers treatment and having a maximum urinary flow rate of less than 15ml/sec.We identified patients who were diagnosed with benign prostate hyperplasia (BPH and had a maximum uroflow rate of less than 15ml/sec between 1 January, 2002 to 31 December, 2011 from Taiwan's National Health Insurance Research Database into study group (n = 303. The control cohort included four BPH/LUTS patients without 5ARI used for each study group, randomly selected from the same dataset (n = 1,212. Each patient was monitored to identify those who subsequently developed prostate surgery and acute urine retention.Prostate surgery and acute urine retention are detected in 5.9% of control group and 8.3% of study group during 10-year follow up. Compared with the control group, there was increase in the risk of prostate surgery and acute urine retention in the study group (HR = 1.83, 95% CI: 1.16 to 2.91 after adjusting for age, comorbidities, geographic region and socioeconomic status.Maximum urine flow rate of less than 15ml/sec is a risk factor of urinary retention and subsequent prostate surgery in BPH patients receiving alpha-1 blocker therapy. This result can provide a reference for clinicians.

Full Text Available Prostatic cysts are rare entities. Mostly, they originate from the posterior area of the prostate and asymptomatic. Anterior location of the prostatic cyst is rarer than posterior. The prostatic cyst in a 41 year-old man presenting with acute urinary retansion. Transurethral resection (TUR of the cyst was performed, which revealed a benign cyst lined with columnar epithelium and proliferative urothelial lining on histopathological evaluation. Prostatic cysts particularly in young men with obstructive lower urinary tract symptoms are rarely seen. Management of the prostatic cyst with TUR seems to be a minimally invasive approach with successful outcomes.

Full Text Available OBJECTIVE: Patients can experience urinary retention (UR after Holmium laser enucleation of the prostate (HoLEP that requires bladder distension during the procedure. The aim of this retrospective study is to identify factors affecting the UR after HoLEP. MATERIALS AND METHODS: 336 patients, which underwent HoLEP for a symptomatic benign prostatic hyperplasia between July 2008 and March 2012, were included in this study. Urethral catheters were routinely removed one or two days after surgery. UR was defined as the need for an indwelling catheter placement following a failure to void after catheter removal. Demographic and clinical parameters were compared between the UR (n = 37 and the non-urinary retention (non-UR; n = 299 groups. RESULTS: The mean age of patients was 68.3 (±6.5 years and the mean operative time was 75.3 (±37.4 min. Thirty seven patients (11.0% experienced a postoperative UR. UR patients voided catheter free an average of 1.9 (±1.7 days after UR. With regard to the causes of UR, 24 (7.1% and 13 (3.9% patients experienced a blood clot-related UR and a non-clot related UR respectively. Using multivariate analysis (p0.05. CONCLUSIONS: De novo UR after HoLEP was found to be self-limited and it was not related to learning curve, patient age, diabetes, or operative time. Efficient morcellation and careful control of bleeding, which reduces clot formation, decrease the risk of UR after HoLEP.

Postoperative urinary retention (POUR) is common in neurosurgical patients. The use of alpha-blockade therapy, such as tamsulosin, has benefited many patients with a history of obstructive uropathy by decreasing lower urinary tract symptoms such as distension, infections, and stricture formation, as well as the incidence of POUR. For this study, we targeted patients who had undergone spinal surgery to examine the prophylactic effects of tamsulosin. Increased understanding of this therapy will assist in minimizing the morbidity of spinal surgery. We enrolled 95 male patients undergoing spine surgery in a double-blind, randomized, placebo-controlled trial. Patients were randomly assigned to receive either preoperative tamsulosin (N = 49) or a placebo (N = 46) and then followed-up prospectively for the development of POUR after removal of an indwelling urinary catheter (IUC). They were also followed-up for the incidence of IUC reinsertions. The rate of developing POUR was similar in both the groups. Of the 49 patients given tamsulosin, 16 (36%) developed POUR compared to 13 (28%) from the control group ( P = 0.455). In the control group, 5 (11%) patients had IUC re-inserted postoperatively, whereas 7 (14%) patients in the tamsulosin group had IUC re-inserted postoperatively ( P = 0.616). In patients suffering from axial-type symptoms (i.e., mechanical back pain), 63% who received tamsulosin and 18% from the control group ( P = 0.048) developed POUR. Overall, there was no statistically significant difference in the rates of developing POUR among patients in either group. POUR is caused by a variety of factors, and further studies are needed to shed light on its etiology.

Herlyn-Werner-Wunderlich (HWW) syndrome is a rare müllerian duct anomaly with uterus didelphys, unilateral obstructed hemivagina, and ipsilateral renal agenesis. Patients with this syndrome generally present after menarche with pelvic pain and mass and, rarely, primary infertility in later years. Strong suspicion and knowledge of this syndrome are mandatory for an accurate diagnosis. A 14-year-old female patient presented with acute retention of urine and abdominopelvic pain. Her condition was diagnosed with the use ultrasonography and magnetic resonance imaging as a case of HWW syndrome. She was treated with vaginal hemiseptal resection. The HWW syndrome should be considered among the differential diagnoses in girls with renal anomalies presenting with pelvic mass, symptoms of acute abdominal pain, and acute urinary retention.

Urinary retention and micturition disorders after overdistension are clinically well-known complications of subvesical obstruction. We attempted to evaluate whether bladder overdistension influences bladder response and whether overdistension supports detrusor decompensation. Following lumbal laminectomy in 9 male foxhounds, the sacral anterior roots S2 and S3 were placed into a modified Brindley electrode for reproducible and controlled detrusor activation. The bladder was filled in stages of 50 ml from 0 to 700 ml, corresponding to an overdistension. At each volume, the bladder response during sacral anterior root stimulation was registered. After overdistension, the bladder was refilled stepwise from 0 to 300 ml and stimulated. In all dogs, the bladder response was influenced by the intravesical volume. The maximum pressure (mean 69.1 cm H(2)O) was observed at mean volume of 100 ml. During overdistension, a significant reduction in bladder response of more than 80% was seen. After overdistension, a significant reduction in intravesical pressure of 19.0% was observed. In 2 cases, reduction in bladder response was more than 50% after a single overdistension. We conclude that motoric bladder function is influenced during and after overdistension. A single bladder overdistension can support acute and long-lasting detrusor decompensation. In order to protect motoric bladder function, bladder overdistension must be prevented.

OBJECTIVES: To estimate the prevalence of urinary tract infection in infants and children with bronchiolitis. METHODS: A retrospective cross-sectional study involving patients zero to 24 months of age who were hospitalized with acute bronchiolitis was conducted. RESULTS: A total of 835 paediatric patients with acute bronchiolitis were admitted to the paediatric ward between January 2010 and December 2012. The mean (± SD) age at diagnosis was 3.47±2.99 months. There were 325 (39%) girls and 510 (61%) boys. For the purpose of data analysis, the patient population was divided into three groups: group 1 included children hospitalized with respiratory syncytial virus (RSV) bronchiolitis; group 2 included children hospitalized with clinical bronchiolitis with no virus detected; and group 3 included children hospitalized with clinical bronchiolitis due to a respiratory virus other than RSV. Results revealed that urinary tract infection was present in 10% of patients, and was most common in group 3 (13.4%) followed by group 2 (9.7%), and was least common in group 1 (6%) (P=0.030). CONCLUSIONS: The possibility of a urinary tract infection should be considered in a febrile child with a diagnosis of bronchiolitis, particularly if the trigger is a respiratory virus other than RSV.

Full Text Available Cosmetic laser use has many pros and cons. The worldwide use of laser for body hair removal has led to many medical complications. Unsupervised use of the laser for hair removal in vulva may result in many problems and can merely damage the vulva, although rarely, affecting the body image. This rare and novel case report is a 21 year old virgin who presented with acute urinary retention and cryptomenorrhea due to complete synlabia secondary to unsupervised vulval laser hair removal. The urinary retention was relieved by suprapubic catheterization initially. During examination under anesthesia, the fused labia were separated by a surgical incision with drainage of hematocolpos and then, a Foley's urethral catheter was inserted. She had an uneventful recovery. We report this case to emphasize on the supervised use of laser by trained and qualified personnel for hair removal in vulva to minimize its complications.

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

A single serum creatinine measurement cannot distinguish acute kidney injury from chronic kidney disease or prerenal azotemia. To test the sensitivity and specificity of a single measurement of urinary neutrophil gelatinase-associated lipocalin (NGAL) and other urinary proteins to detect acute kidney injury in a spectrum of patients. Prospective cohort study. Emergency department of Columbia University Medical Center, New York, New York. 635 patients admitted to the hospital with acute kidney injury, prerenal azotemia, chronic kidney disease, or normal kidney function. Diagnosis of acute kidney injury was based on the RIFLE (risk, injury, failure, loss, and end-stage) criteria and assigned by researchers who were blinded to experimental measurements. Urinary NGAL was measured by immunoblot, N-acetyl-beta-d-glucosaminidase (NAG) by enzyme measurement, alpha1-microglobulin and alpha(1)-acid glycoprotein by immunonephelometry, and serum creatinine by Jaffe kinetic reaction. Experimental measurements were not available to treating physicians. Patients with acute kidney injury had a significantly elevated mean urinary NGAL level compared with the other kidney function groups (416 microg/g creatinine [SD, 387]; P = 0.001). At a cutoff value of 130 microg/g creatinine, sensitivity and specificity of NGAL for detecting acute injury were 0.900 (95% CI, 0.73 to 0.98) and 0.995 (CI, 0.990 to 1.00), respectively, and positive and negative likelihood ratios were 181.5 (CI, 58.33 to 564.71) and 0.10 (CI, 0.03 to 0.29); these values were superior to those for NAG, alpha1-microglobulin, alpha1-acid glycoprotein, fractional excretion of sodium, and serum creatinine. In multiple logistic regression, urinary NGAL level was highly predictive of clinical outcomes, including nephrology consultation, dialysis, and admission to the intensive care unit (odds ratio, 24.71 [CI, 7.69 to 79.42]). All patients came from a single center. Few kidney biopsies were performed. A single measurement

To examine the influence of mercuric chloride (HgCl{sub 2})-induced acute renal damage on urinary excretion of furosemide, HgCl{sub 2} or its vehicle along was given intraperitoneally to Wistar rats. The following two experiments were done. Study 1: three percent body weight (b.w.) of 1% NaCl solution or furosemide in 3% b.w. of 1% NaCl solution was given orally before and after HgCl{sub 2} treatment, and an 8-hour urine was collected. Study 2: furosemide was given orally, and blood samples were obtained at 1, 2, 3, 4, 6 and 8 hours after administration. Urinary excretion of N-acetyl-{beta}-D-glucosaminidase increased, and urine volume and urinary excretions of furosemide and sodium decreased in the HgCl{sub 2}-treated rats. There were significant correlations between the urinary furosemide and its diuretic effects. Regression lines after HgCl{sub 2} were significantly different from those before treatment. The values of absorption as well as elimination rate constant were smaller, while the time to maximum concentration and the elimination half-life were longer in the HgCl{sub 2}-treated rats compared to vehicle-treated animals. These results suggest that the urinary excretion of furosemide and the responsiveness of renal tubular cells to this agent are impaired in rats with HgCl{sub 2}-induced acute renal damage.

Acute Bacterial Prostatitis: Diagnosis and Management.

Science.gov (United States)

Coker, Timothy J; Dierfeldt, Daniel M

2016-01-15

Acute bacterial prostatitis is an acute infection of the prostate gland that causes pelvic pain and urinary tract symptoms, such as dysuria, urinary frequency, and urinary retention, and may lead to systemic symptoms, such as fevers, chills, nausea, emesis, and malaise. Although the true incidence is unknown, acute bacterial prostatitis is estimated to comprise approximately 10% of all cases of prostatitis. Most acute bacterial prostatitis infections are community acquired, but some occur after transurethral manipulation procedures, such as urethral catheterization and cystoscopy, or after transrectal prostate biopsy. The physical examination should include abdominal, genital, and digital rectal examination to assess for a tender, enlarged, or boggy prostate. Diagnosis is predominantly made based on history and physical examination, but may be aided by urinalysis. Urine cultures should be obtained in all patients who are suspected of having acute bacterial prostatitis to determine the responsible bacteria and its antibiotic sensitivity pattern. Additional laboratory studies can be obtained based on risk factors and severity of illness. Radiography is typically unnecessary. Most patients can be treated as outpatients with oral antibiotics and supportive measures. Hospitalization and broad-spectrum intravenous antibiotics should be considered in patients who are systemically ill, unable to voluntarily urinate, unable to tolerate oral intake, or have risk factors for antibiotic resistance. Typical antibiotic regimens include ceftriaxone and doxycycline, ciprofloxacin, and piperacillin/tazobactam. The risk of nosocomial bacterial prostatitis can be reduced by using antibiotics, such as ciprofloxacin, before transrectal prostate biopsy.

A New Perspective on Nursing Retention: Job Embeddedness in Acute Care Nurses.

Hopson, Michelle; Petri, Laura; Kufera, Joseph

Job embeddedness considers job satisfaction while incorporating the concepts of environment and community. This exploratory, mixed methods study used the Job Embeddedness Instrument to examine factors that influence retention of acute care nurses. Qualitative methods informed the survey results. Increasing age, ties to community, and peer relationships were found to be most indicative of job embeddedness. Nursing professional development practitioners can impact retention by focusing on factors that encourage nurses to stay in their positions.

BACKGROUND: Long-course preoperative chemoradiotherapy (chemo-RT) improves outcomes for rectal cancer patients, but acute side effects during treatment may cause considerable patient discomfort and may compromise treatment compliance. We developed a dose-response model for acute urinary toxicity...... based on a large, single-institution series. MATERIAL AND METHODS: In total 345 patients were treated with (chemo-)RT for primary rectal cancer from January 2007 to May 2012.

High-powered photoselective vaporization of the prostate (PVP) is a relatively new addition in the armamentarium against bladder outlet obstruction due to BPH. With BPH, the prostate undergoes stromal and epithelial hyperplasia, particularly in the transitional zone, mediated by dihydrotestosterone (DHT). This periurethral enlargement can compress the prostatic urethra leading to bladder outlet obstruction and eventually urinary retention. Treatment of uncomplicated symptomatic BPH has evolved from the standard transurethral resection of the prostate (TURP) to multiple medical therapies and the putative minimally invasive surgical procedures. These include microwave ablation, needle ablation, balloon dilation, stents, as well as fluid based thermo-therapy, ultrasound therapy and cryotherapy. Different forms of lasers have been applied to treat BPH with variable short and long term benefits of urinary symptoms. However, the controversy remains about each laser regarding its technical applicability and efficacy.

Full Text Available Urinary bladder rupture is usually found due to blunt or penetrating traumas and iatrogenic injuries, and spontaneous intraperitoneal perforation is very rare. 57 years old male patient was consulted to general surgery department due to abdominal pain, nausia-vomiting and fever. He had Diabetes Mellitus, Multiple Sclerosis, Leriche Syndrome and operation for benign prostatic hypertrophy 5 years ago on his medical history which the case catheterised him urinary bladder himself frequently in nonsterile conditions. He did not care about sterility. On physical examination, suprapubic defence and rebound was noted more prominently on right lower quadrant. He was taken to operating room with the diagnosis of acute abdomen. On exploration, infection was seen on all layers of the whole urinary bladder, abscess formation and necrosis causing a microperforation which is detected by methylene blue was also present. Intraabdominal abscess drainage, cystostomy and primary suturing of the urinary bladder was performed. Patient died due to sepsis at the 9.th post operative day.

Background A single serum creatinine measurement cannot distinguish acute kidney injury from chronic kidney disease or prerenal azotemia. Objective To test the sensitivity and specificity of a single measurement of urinary neutrophil gelatinase–associated lipocalin (NGAL) and other urinary proteins to detect acute kidney injury in a spectrum of patients. Design Prospective cohort study. Setting Emergency department of Columbia University Medical Center, New York, New York. Participants 635 patients admitted to the hospital with acute kidney injury, prerenal azotemia, chronic kidney disease, or normal kidney function. Measurements Diagnosis of acute kidney injury was based on the RIFLE (risk, injury, failure, loss, and end-stage) criteria and assigned by researchers who were blinded to experimental measurements. Urinary NGAL was measured by immunoblot, N-acetyl-β-D-glucosaminidase (NAG) by enzyme measurement, α1-microglobulin and α1-acid glycoprotein by immunonephelometry, and serum creatinine by Jaffe kinetic reaction. Experimental measurements were not available to treating physicians. Results Patients with acute kidney injury had a significantly elevated mean urinary NGAL level compared with the other kidney function groups (416 μg/g creatinine [SD, 387]; P = 0.001). At a cutoff value of 130 μg/g creatinine, sensitivity and specificity of NGAL for detecting acute injury were 0.900 (95% CI, 0.73 to 0.98) and 0.995 (CI, 0.990 to 1.00), respectively, and positive and negative likelihood ratios were 181.5 (CI, 58.33 to 564.71) and 0.10 (CI, 0.03 to 0.29); these values were superior to those for NAG, α1-microglobulin, α1-acid glycoprotein, fractional excretion of sodium, and serum creatinine. In multiple logistic regression, urinary NGAL level was highly predictive of clinical outcomes, including nephrology consultation, dialysis, and admission to the intensive care unit (odds ratio, 24.71 [CI, 7.69 to 79.42]). Limitations All patients came from a single

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

Splenic rupture following idiopathic rupture of the urinary bladder presenting as acute abdomen

Jurisic D

2007-01-01

Full Text Available Idiopathic rupture of the urinary bladder is an uncommon condition and represents less than 1% of all bladder rupture cases. In most of the cases the main etiological factor was heavy alcohol ingestion. A combined injury of the spleen and bladder is a very rare condition that is almost often associated with trauma and foreign bodies. In this paper we present the extremely rare clinical course of acute abdomen caused by a combined spontaneous intraperitoneal injury; spontaneous rupture of the urinary bladder and spleen. According to our opinion, spontaneous bladder rupture caused by bladder distension due to alcohol ingestion led to urinary ascites and abdominal distension. Finally, repeated minor abdominal blunt trauma during everyday life, to a moderately distended abdomen caused a spontaneous splenic rupture in the patient with abnormal coagulation studies.

Full Text Available Transurethral resection of the prostate (TURP is the most common surgical procedure for relieving symptoms of benign prostatic hyperplasia. Here, we report our experience of current indications for TURP and their associated outcomes at Kaohsiung Medical University Hospital (KMUH. A total of 111 patients who underwent TURP at KMUH between May 2000 and December 2001 were included in this retrospective review. For each patient, the surgical indication was categorized into acute urinary retention, chronic complications (including renal impairment, recurrent urinary infection, bladder stone/diverticulum, post-void residue, and recurrent hematuria, and symptomatic prostatism. Thirty-five patients (31% had acute urinary retention, 28 (27% had chronic complications, and 48 (42% had symptomatic prostatism. Most patients chose TURP only when medical treatment had failed to relieve symptoms, no matter what category they belonged to. Patients with acute urinary retention and chronic complications had larger prostates (p = 0.002 and more tissue resected (p = 0.05 than those with symptomatic prostatism. Patients with acute urinary retention seemed to be at greater risk of postoperative complications such as recurrent urinary retention and urinary tract infection. We suggest that urodynamic study may be necessary to rule out concomitant bladder dysfunction before surgery and that adequate prophylactic antibiotic treatment be used to decrease the risk of urinary tract infection during or after TURP, especially when pyuria is noted preoperatively in patients with acute urinary retention.

President Woodrow Wilson was never able to gain ratification of the Treaty of Versailles, the peace accord to end World War I. Before he could convince the American people of the importance of ratification, Wilson suffered a stroke followed by life threatening urinary sepsis due to urinary retention, and was treated by the father of modern urology, Hugh Hampton Young. The effects of these health problems are examined in the context of their implications on international affairs. Biographical sources and primary documentation of Wilson's physicians were reviewed to determine the effect of Wilson's stroke on his voiding habits. Hugh Hampton Young's evaluation and decision making is examined in depth. In the fall of 1919 President Wilson was recovering from a stroke. Shortly after the stroke his preexisting voiding dysfunction progressed to urinary retention from which urinary sepsis developed. Hugh Hampton Young advised on Wilson's case and counseled patience over surgery. The President began voiding spontaneously and recovered from sepsis. The illness left him severely weakened and unable to mount an aggressive campaign to persuade the U.S. Senate of the importance of ratifying the Treaty of Versailles. His personal physician, Admiral Cary T. Grayson, stated that the President was mentally never the same after the sepsis. Wilson's voiding dysfunction contributed to his inability to win approval for the Treaty of Versailles and the League of Nations. As a result, the United States returned to a policy of isolationism and Europe plunged into 2 decades of upheaval, leading to World War II.

Acute kidney injury (AKI) in the neonatal intensive care setting is multifactorial and is associated with significant morbidity and mortality. This study evaluates the utility of novel urinary biomarkers to predict the development and/or severity AKI in preterm infants. We performed a case-control study on a prospective cohort of preterm infants (<32 wk), to compare seven urine biomarkers between 25 infants with AKI and 20 infants without AKI. Infants with AKI had significantly higher neutrophil gelatinase-associated lipocalin (NGAL) (median, control (CTRL) vs. AKI; 0.598 vs. 4.24 µg/ml; P < 0.0001). In contrast, urinary epidermal growth factor (EGF) levels were significantly lower in infants who developed AKI compared to controls (median, CTRL vs. AKI; 0.016 vs. 0.006 µg/ml; P < 0.001). The area under the curve (AUC) for NGAL for prediction of stage I AKI on the day prior to AKI diagnosis (day-1) was 0.91, and for the prediction of stage II/III, AKI was 0.92. Similarly, urine EGF was a predictor of renal injury on day -1 (AUC: 0.97 for stage I and 0.86 for stage II/III AKI). Urinary biomarkers may be useful to predict AKI development prior to changes in serum creatinine (SCr) in preterm infants.

In practice, trauma and orthopedic surgery during spinal anesthesia are often performed with routine urethral catheterization of the bladder to prevent an overdistention of the bladder. However, use of a catheter has inherent risks. Ultrasound examination of the bladder (Bladderscan) can precisely determine the bladder volume. Thus, the aim of this study was to identify parameters indicative of urinary retention after low-dose spinal anesthesia and to develop a simple algorithm for patient care. This prospective pilot study approved by the Ethics Committee enrolled 45 patients after obtaining their written informed consent. Patients who underwent arthroscopic knee surgery received low-dose spinal anesthesia with 1.4 ml 0.5% bupivacaine at level L3/L4. Bladder volume was measured by urinary bladder scanning at baseline, at the end of surgery and up to 4 h later. The incidence of spontaneous urination versus catheterization was assessed and the relative risk for catheterization was calculated. Mann-Whitney test, chi(2) test with Fischer Exact test and the relative odds ratio were performed as appropriate. *P 300 ml postoperatively had a 6.5-fold greater likelihood for urinary retention. In the management of patients with short-lasting spinal anesthesia for arthroscopic knee surgery we recommend monitoring bladder volume by Bladderscan instead of routine catheterization. Anesthesiologists or nurses under protocol should assess bladder volume preoperatively and at the end of surgery. If bladder volume is >300 ml, catheterization should be performed in the OR. Patients with a bladder volume of 500 ml.

Inguinal hernia repair is a common general surgery procedure with low morbidity. However, postoperative urinary retention (PUR) occurs in up to 22% of patients, resulting in further extraneous treatments.This single institution series investigates whether patient comorbidities, surgical approaches, and anesthesia methods are associated with developing PUR after inguinal hernia repairs. This is a single institution retrospective review of inguinal hernia from 2012 to 2015. PUR was defined as patients without a postoperative urinary catheter who subsequently required bladder decompression due to an inability to void. Univariate and multivariate logistic regressions were performed to quantify the associations between patient, surgical, and anesthetic factors with PUR. Stratification analysis was conducted at age of 50 years. 445 patients were included (42.9% laparoscopic and 57.1% open). Overall rate of PUR was 11.2% (12% laparoscopic, 10.6% open, and p = 0.64). In univariate analysis, PUR was significantly associated with patient age >50 and history of benign prostatic hyperplasia (BPH). Risk stratification for age >50 revealed in this cohort a 2.49 times increased PUR risk with lack of intraoperative bladder decompression (p = 0.013). At our institution, we found that patient age, history of BPH, and bilateral repair were associated with PUR after inguinal hernia repair. No association was found with PUR and laparoscopic vs open approach. Older males may be at higher risk without intraoperative bladder decompression, and therefore, catheter placement should be considered in this population, regardless of surgical approach.

2017-04-01

Full Text Available Background: Acute appendicitis is the most common abdominal surgical emergency especially in children and young adults. The diagnosis of appendicitis is difficult because half the cases are incorrectly identified. Serotonin was defined as a good diagnostic marker for many inflammations including appendicitis and it is metabolite into 5-hydroxyindolacetic acid (5-HIAA to be excreted in urine. 5-HIAA is suggested to be of diagnostic importance in the detection of this disease. The aim of this study was to evaluate the diagnostic importance of urinary-5-HIAA as an added parameter to Alvarado score. Methods: Seventy patients (35 females and 35 males with acute appendicitis (35 were mild and 35 severe-perforated and gangrenous were included in this study and 70 healthy individuals were taken as a control group. Urinary-5-HIAA was estimated in all patients and control group using ELISA method. Results: Sensitivity for the mild group is 94.2%, specificity 100% and diagnostic accuracy is 97.4%, while the sensitivity for the severe group is 37%. It was found that there is a highly significant difference between mild and control groups (P<0.05. The diagnostic accuracy for the mild group is 97.4% and for the severe is 68.5%. Conclusion: We conclude that urinary-5-HIAA is a high sensitive test for early detection of acute appendicitis.

Schizophrenia is associated with increased infections. We previously found an association between urinary tract infection (UTI) and acute psychosis in adults. The aims of this study were to 1) evaluate the prevalence of UTI at the time of admission in children and adolescents with non-affective psychosis and psychotic depression versus those with non-psychotic major depressive disorder, and 2) compare demographic and clinical features between children and adolescents with acute psychosis with and without comorbid UTI. We performed a retrospective chart review of 227 subjects ages 10-18 who were hospitalized between 2005 and 2014 for an acute episode of DSM-IV non-affective psychosis (schizophrenia, schizoaffective disorder, psychosis NOS, or delusional disorder; n=80), major depressive disorder (MDD) with psychotic features (n=47); or MDD without psychotic features (n=100). The prevalence of UTI was 20% in non-affective psychosis, 9% in MDD with psychotic features, and 13% in non-psychotic MDD. After controlling for potential confounders, UTI was 3.5 times more likely in subjects with non-affective psychosis than non-psychotic MDD (OR=3.5, 95% CI 1.3-9.2, p=0.01). Subjects with UTI had a higher prevalence of manic symptoms, but otherwise there were no associations between clinical characteristics and UTI in acute psychosis. We found an association between UTIs and children and adolescents with acute non-affective psychosis. The results highlight the potential importance of screening for comorbid UTI in patients with acute psychosis. Copyright © 2016 Elsevier B.V. All rights reserved.

Plutonium fecal and urinary excretion functions: Derivation from a systematic whole-body retention function

International Nuclear Information System (INIS)

Sun, C.; Lee, D.

1999-01-01

Liver-bile secretion directly influences the content of plutonium in feces. To assess the reliability of plutonium metabolic models and to improve the accuracy of interpreting plutonium fecal data, the authors developed a compartmental model that simulates the metabolism of plutonium in humans. With this model, they can describe the transport of plutonium contaminants in the systemic organs and tissues of the body, including fecal and urine excretions, without using elaborate kinetic information. The parameter values of the models, which describe the translocation rates and recycling of plutonium in the body, can be derived from a multi-term exponential systemic function for whole-body retention. The analytical derivations and algorithms for solving translocation parameter values are established for the model and illustrated by applying them to the biokinetics and bioassay of plutonium. This study describes how to (1) design a physiological model for incorporating liver biliary secretion and for obtaining a fecal-excretion function, (2) develop an analytical solution for identifying the translocation-parameter values incorporating the recycling of plutonium in the body, and (3) derive a set of urinary and fecal excretion-functions from a published systemic whole-body retention function, generally acknowledged to be accurate, as a real and practical example

The authors report an original case of acute myeloid leukaemia (AML) presenting in the form of acute urinary retention, confirmed by prostatic biopsy, with complete absence of any non-urological clinical features. Prostatic sites of leukaemia are frequent and classically reported, but often occur during the course of known leukaemia, and are rarely symptomatic, justifying biopsies in the presence of any prostatic symptoms. Immunolabelling represents the key to the diagnosis in the presence of undifferentiated cells demonstrated on prostatic biopsies. The outcome was fatal in this case, despite early chemotherapy. The clinical features, clinical course and therapeutic aspects of prostatic leukaemia are discussed.

Edis, R H

1981-01-01

Two definite and 2 probable cases of anogenital herpes simplex and sacral radiculitis are described. Symptoms were typical and consisted of paraesthesia and neuralgic pain in the perineum and legs, urinary retention and constipation occurring within several days to a week after an anogenital herpetic eruption. However, at presentation only 1 case had an obvious history of anogenital herpes simplex. Neurological signs were not striking and consisted of a reduced appreciation of light touch and pin prick over the sacral dermatomes and in 2 cases reduced anal sphincter tone. CSF examination in 3 patients showed a lymphocytosis. Bladder catheterisation was required for up to 2 weeks in 2 patients. The paraesthesia persisted for weeks to months. It should be more widely recognised that anogenital herpes simplex, with sacral radiculitis, is probably the commonest cause of acute retention of urine in young sexually active people.

Urinary NGAL Ratio Is Not a Sensitive Biomarker for Monitoring Acute Tubular Injury in Kidney Transplant Patients: NGAL and ATI in Renal Transplant Patients

Directory of Open Access Journals (Sweden)

Jessica K. Kaufeld

2012-01-01

Full Text Available Urinary neutrophil gelatinase-associated lipocalin (uNGAL is known to predict the prolonged delayed graft function after kidney transplantation. We examined the relation of uNGAL with histological findings of acute tubular injury (ATI. Analyses were made in biopsies taken at 6 weeks, 3 months, and 6 months after kidney transplantation. uNGAL was measured in the spot urines, normalized to urinary creatinine excretion, and correlated to biopsy findings and clinical, laboratory, and demographic variables. Controls included healthy individuals, individuals after kidney donation and ICU patients with acute kidney failure. Renal transplant recipients without ATI did not display elevated uNGAL levels compared to the healthy controls. Transplant patients with ATI had a higher uNGAL excretion at 6 weeks than patients without ATI (27,435 versus 13,605 ng/g; P=0.031. This increase in uNGAL was minor compared to ICU patients with acute renal failure (2.05×106 ng/g. Patients with repeated findings of ATI or severe ATI did not have higher urinary NGAL levels compared to those with only one ATI finding or moderate ATI. Female recipient gender and urinary tract infection were identified as potential confounders. uNGAL has a relation with histological signs of acute tubular injury. The usability of this biomarker in renal allograft recipients is limited because of the low sensitivity.

2013-08-01

Postoperative urinary retention (PUR) is a common postsurgical complication. Early detection and management of PUR is of particular concern to nurses working in the postanesthesia care unit (PACU) because a single episode of bladder distention may result in permanent bladder damage. A clinical audit (CA) was conducted that examined the risk factors that may contribute to the development of PUR in the PACU. The CA was conducted over a 1-week time period and used a data collection tool that was developed from the current literature. A total of 34 patients met the inclusion criteria for the CA, and a prevalence rate of 20.6% was reported, which was consistent with prevalence rates reported by larger research studies. Despite the small sample size of this CA, results suggested that PUR should be of concern to nurses in the PACU. Recommendations included the development and implementation of a guideline relating to bladder scanning in the PACU and modification of existing PACU discharge criteria to include bladder management.

Purpose: To assess, in a nationwide multi-institutional cohort study begun in 2005 and in which 6927 subjects were enrolled by 2010, the urinary and rectal toxicity profiles of subjects who enrolled during the first 2 years, and evaluate the toxicity profiles for permanent seed implantation (PI) and a combination therapy with PI and external beam radiation therapy (EBRT). Methods and Materials: Baseline data for 2339 subjects out of 2354 patients were available for the analyses. Toxicities were evaluated using the National Cancer Institute's Common Terminology Criteria for Adverse Events, and the International Prostate Symptom Scores were recorded prospectively until 36 months after radiation therapy. Results: Grade 2+ acute urinary toxicities developed in 7.36% (172 of 2337) and grade 2+ acute rectal toxicities developed in 1.03% (24 of 2336) of the patients. Grade 2+ late urinary and rectal toxicities developed in 5.75% (133 of 2312) and 1.86% (43 of 2312) of the patients, respectively. A higher incidence of grade 2+ acute urinary toxicity occurred in the PI group than in the EBRT group (8.49% vs 3.66%; P<.01). Acute rectal toxicity outcomes were similar between the treatment groups. The 3-year cumulative incidence rates for grade 2+ late urinary toxicities were 6.04% versus 4.82% for the PI and the EBRT groups, respectively, with no significant differences between the treatment groups. The 3-year cumulative incidence rates for grade 2+ late rectal toxicities were 0.90% versus 5.01% (P<.01) for the PI and the EBRT groups, respectively. The mean of the postimplant International Prostate Symptom Score peaked at 3 months, but it decreased to a range that was within 2 points of the baseline score, which was observed in 1625 subjects (69.47%) at the 1-year follow-up assessment. Conclusions: The acute urinary toxicities observed were acceptable given the frequency and retention, and the late rectal toxicities were more favorable than those of other

Recent meta-analyses support the utility of urinary biomarkers for the diagnosis and prognosis of acute kidney injury. It is critical to establish optimal sample handling conditions for short-term processing and long-term urinary storage prior to widespread clinical deployment and meaningful use in prospective clinical trials. Prospective study. 80 children (median age, 1.1 [IQR, 0.5-4.2] years) undergoing cardiac surgery with cardiopulmonary bypass at our center. 50% of patients had acute kidney injury (defined as ≥50% increase in serum creatinine from baseline). We tested the effect on biomarker concentrations of short-term urine storage in ambient, refrigerator, and freezer conditions. We also tested the effects of multiple freeze-thaw cycles, as well as prolonged storage for 5 years. Urine concentrations of neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule 1 (KIM-1), and interleukin 18 (IL-18). All biomarkers were measured using commercially available kits. All 3 biomarkers were stable in urine stored at 4°C for 24 hours, but showed significant degradation (5.6%-10.1% from baseline) when stored at 25°C. All 3 biomarkers showed only a small although significant decrease in concentration (0.77%-2.9% from baseline) after 3 freeze-thaw cycles. Similarly, all 3 biomarkers displayed only a small but significant decrease in concentration (0.84%-3.2%) after storage for 5 years. Only the 3 most widely studied biomarkers were tested. Protease inhibitors were not evaluated. Short-term storage of urine samples for measurement of NGAL, KIM-1, and IL-18 may be performed at 4°C for up to 24 hours, but not at room temperature. These urinary biomarkers are stable at -80°C for up to 5 years of storage. Our results are reassuring for the deployment of these assays as biomarkers in clinical practice, as well as in prospective clinical studies requiring long-term urine storage.

Full Text Available Recent studies have shown that blueberries may have cardiovascular and cognitive health benefits. In this work, we investigated the profile of plasma and urine (polyphenol metabolites after acute and daily consumption of wild blueberries for 30 days in 18 healthy men. The inter-individual variability in plasma and urinary polyphenol levels was also investigated. Blood samples were collected at baseline and 2 h post-consumption on day 1 and day 30. Twenty-four-hour urine was also collected on both days. A total of 61 phenolic metabolites were quantified in plasma at baseline, of which 43 increased after acute or chronic consumption of blueberries over one month. Benzoic and catechol derivatives represented more than 80% of the changes in phenolic profile after 2 h consumption on day 1, whereas hippuric and benzoic derivatives were the major compounds that increased at 0 and 2 h on day 30, respectively. The total (polyphenol urinary excretion remained unchanged after 30 days of wild blueberry intake. The inter-individual variability ranged between 40%–48% in plasma and 47%–54% in urine. Taken together, our results illustrate that blueberry (polyphenols are absorbed and extensively metabolized by phase II enzymes and by the gut microbiota, leading to a whole array of metabolites that may be responsible for the beneficial effects observed after blueberry consumption.

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

Full Text Available Objective. To compare the effectiveness and safety of acupuncture versus intramuscular injection of neostigmine. Methods. Databases including CNKI, VIP, WanFang, SinoMed, PubMed, Cochrane Library, and clinicaltrials.gov database were retrieved for relevant literature, with the retrieval deadline being November 2017. Two reviewers independently screened, selected, and extracted data and validated the results. The methodological quality was evaluated with the “Risk of Bias” tool, and the meta-analysis was performed by using the RevMan 5.3.5 software. Results. Totally 953 patients with postpartum urinary retention from 15 randomized controlled trials entered the meta-analysis. 12 articles compared the clinical cure rate of acupuncture alone versus intramuscular injection of neostigmine and found the cure rate in the acupuncture group was 2 times that in the neostigmine group (RR, 1.91; 95% CI: 1.66–2.19. 15 articles compared the clinical effectiveness rate of acupuncture alone with that of intramuscular injection of neostigmine and found the clinical effectiveness rate was 28% higher in the acupuncture group than in the neostigmine group (RR: 1.28; 95% CI: 1.16–1.42. No adverse event was reported in the acupuncture group. Conclusion. Acupuncture alone is more effective in treating postpartum urinary retention than intramuscular injection of neostigmine, with good safety profile. Therefore, it is a feasible and valuable technique in clinical settings.

99mTc-DMSA scintigraphy in acute urinary tract infection in children

24 children with symptomatic urinary tract infection (UTI) underwent systematically ultrasound studies (US) and 99m Tc-DMSA renal scans. Among the 15 patients considered as acute pyelonephritis (APN) on clinical grounds, the scan was abnormal in 12 cases, in contrast with only 1 abnormal scan in the clinical subgroup of the lower UTI. Among the 10 abnormal scans that were repeated later on, 6 did completely normalize. US showed only once a parenchymal appearance suggestive for APN. Our findings suggest that the DMSA scan has to be considered at present as the most sensitive imaging technique for the detection of APN. (orig.)

To assess whether immediate (0h), intermediate (after 6h) or delayed (after 24h) removal of an indwelling urinary catheter after uncomplicated abdominal hysterectomy can affect the rate of re-catheterization due to urinary retention, rate of urinary tract infection, ambulation time and length of hospital stay. Prospective randomized controlled trial conducted at Suez Canal University Hospital, Egypt. Two hundred and twenty-one women underwent total abdominal hysterectomy for benign gynecological diseases and were randomly allocated into three groups. Women in group A (73 patients) had their urinary catheter removed immediately after surgery. Group B (81 patients) had the catheter removed 6h post-operatively while in group C (67 patients) the catheter was removed after 24h. The main outcome measures were the frequency of urinary retention, urinary tract infections, ambulation time and length of hospital stay. There was a significantly higher number of urinary retention episodes requiring re-catheterization in the immediate removal group compared to the intermediate and delayed removal groups (16.4% versus 2.5% and 0% respectively). Delayed urinary catheter removal was associated with a higher incidence of urinary tract infections (15%), delayed ambulation time (10.3h) and longer hospital stay (5.6 days) compared to the early (1.4%, 4.1h and 3.2 days respectively) and intermediate (3.7%, 6.8h and 3.4 days respectively) removal groups. Removal of the urinary catheter 6h postoperatively appears to be more advantageous than early or late removal in cases of uncomplicated total abdominal hysterectomy.

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

Rothrock, J F; Walicke, P A; Swenson, M R

1986-11-01

Active infection with herpes zoster may cause acute urinary retention, especially when it involves sacral dermatomes. Although frank retention usually develops days to weeks after eruption of the typical rash, bladder incompetence infrequently develops first, raising concern over other, more ominous etiologies. In the case presented, rash appearance was delayed until six weeks after the initial onset of urinary retention, a much longer interval than previously reported. Occult herpes zoster infection should be considered in patients presenting with an acute neurogenic bladder of obscure cause.

In acute gastroenteritis (AG) fecal losses may cause depletion of sodium (NaD) which may not be recognized because of normal plasma Na (pNa) concentrations. We studied the incidence of this state of normonatremic sodium depletion (NNaD) and the suitability of the urinary Na/urinary creatinine ratio (uNa/uCr) for diagnosing NNaD. 16 AG- and 16 healthy control children aged 0.8-15.0 years. Prospective cross sectional pilot study. Measurements of Na, K and creatinine in plasma (p) and urine (u). Calculation of uNa/uCr Ratio, fractional excretion of Na (FENa) and uNa/uK ratio as the hitherto best known parameters of prerenal Na depletion, respectively. pNa concentrations were normal in 15/16 AG patients (93.8%) with only one subnormal value of 133 mmol/L, and a mean value of 137.9±2.3 mmol/L not different from the normal control group (139.4±2.2 mmol/L). Also, mean uNa concentrations and uNa/uK ratios did not differ between both groups. However, uNa/uCr ratios were below normal in 13/16 AG children (81.3%) but normal in all healthy controls with a significantly lower mean value in the AG group (12.6±8.8 vs. 31.2±8.3 mmol/mmol; phigh correlation coefficient of r=0.9333. The majority of AG patients was found to have NNaD as determined by uNa/uCr and FENa. Calculation of uNa/uCr may be useful for diagnosing NNaD in AG. © Georg Thieme Verlag KG Stuttgart · New York.

There are conflicting data on the results of irrigation and debridement with component retention in patients with acute periprosthetic hip infections. The goals of this study were to examine contemporary results of irrigation and debridement with component retention for acute infection after primary hip arthroplasty and to identify host, organism, antibiotic, or implant factors that predict success or failure. Ninety hips (57 total hip arthroplasties and 33 hemiarthroplasties) were diagnosed with acute periprosthetic hip infection (using strict criteria) and were treated with irrigation and debridement and component retention between 2000 and 2012. The mean follow-up was 6 years. Patients were stratified on the basis of McPherson criteria. Hips were managed with irrigation and debridement and retention of well-fixed implants with modular head and liner exchange (70%) or irrigation and debridement alone (30%). Seventy-seven percent of patients were treated with chronic antibiotic suppression. Failure was defined as failure to eradicate infection, characterized by a wound fistula, drainage, intolerable pain, or infection recurrence caused by the same organism strain; subsequent removal of any component for infection; unplanned second wound debridement for ongoing deep infection; and/or occurrence of periprosthetic joint infection-related mortality. Treatment failure occurred in 17% (15 of 90 hips), with component removal secondary to recurrent infection in 10% (9 of 90 hips). Treatment failure occurred in 15% (10 of 66 hips) after early postoperative infection and 21% (5 of 24 hips) after acute hematogenous infection (p = 0.7). Patients with McPherson host grade A had a treatment failure rate of 8%, compared with 16% (p = 0.04) in host grade B and 44% in host grade C (p = 0.006). Most treatment failures (12 of 15 failures) occurred within the initial 6 weeks of treatment; failures subsequent to 6 weeks occurred in 3% of those treated with chronic antibiotic

Full Text Available The objective of research was to determine diagnostic efficacy of urinary concentrations of leucine-rich alpha-2-glycoprotein (A2GRL in patients with acute appendicitis. There were included patients with high suspicion of acute appendicitis (group A; cases, n = 30. In group B (controls, n = 30 were included patients with non-surgical abdominal pain who attended to Hospital Central “Dr. Urquinaona”, Maracaibo, Zulia. General characteristics, urinary concentrations of A2GRL and diagnostic efficacy of assay were evaluated. Mean age of patients in group A was 36.3 +/- 8.8 years-old and in group B was 35.8 +/- 9.6 years-old (p = ns. There were not found significant differences in sex distribution, weight and height between groups (p = ns. Urinary concentrations of A2GRL were significantly higher in group A (1543.8 +/- 762.7 ng/mL compared with mean value in patients of group B (774.1 +/- 356.1 ng/mL; p < 0.0001. A2GRL presented a value below curve 0.81. A cut-off value of 1000 ng/mL, showed sensivity 73.3%, specificity 70.9%, positive predictive value 72.4% and negative predictive value 72.4%. It is concluded that urinary concentrations of A2GRL have a high diagnostic efficacy in patients with acute appendicitis

Acute pyelonephritis can have serious complications.

Shields, Joanne; Maxwell, Alexander P

Urinary tract infection (UTI) may predominantly involve the lower urinary tract, i.e. acute cystitis, or upper urinary tract consisting of the renal pelvis and kidney,, i.e. acute pyelonephritis The incidence of acute pyelonephritis is higher in young women than in men but the incidence in men over 65 is similar to that in older women. Women have up to a 10% risk of recurrent acute pyelonephritis in the year following a first acute episode. The equivalent risk in men is 6%. Acute pyelonephritis may be uncomplicated and resolve without serious sequelae. A minority of episodes may be complicated by acute kidney injury, papillary necrosis, renal or perinephric abscess or the development of emphysematous pyelonephritis. Acute pyelonephritis is generally caused by microorganisms ascending from the urethra via the bladder into the upper urinary tract. Rarely the kidney may be seeded by blood-borne infection. Ecoli is the most common uropathogen causing pyelonephritis accounting for 70-90% of infections. Species of Enterococci, Klebsiella, Pseudomonas, Proteus and Staphylococci are responsible for the remaining infections. There is a rising incidence in the community of UTI with bacteria that produce extended spectrum beta-lactamase (ESBL) enzymes. These ESBL bacteria have developed resistance to antibiotics such as penicillin, cephalosporins and increasingly to quinolones. Risk factors for uncomplicated acute pyelonephritis include recent sexual intercourse, acute cystitis, stress incontinence and diabetes and for complicated acute pyelonephritis include pregnancy, diabetes, anatomical abnormalities of the urinary tract and renal calculi.

Acupuncture for Chronic Urinary Retention due to Spinal Cord Injury: A Systematic Review

Directory of Open Access Journals (Sweden)

Jia Wang

2016-01-01

Full Text Available No systematic review has been published on the use of acupuncture for the treatment of chronic urinary retention (CUR due to spinal cord injury (SCI. The aim of this review was to assess the effectiveness and safety of acupuncture for CUR due to SCI. Three randomized controlled trials (RCTs including 334 patients with CUR due to SCI were included. Meta-analysis showed that acupuncture plus rehabilitation training was much better than rehabilitation training alone in decreasing postvoid residual (PVR urine volume (MD −109.44, 95% CI −156.53 to −62.35. Likewise, a combination of acupuncture and aseptic intermittent catheterization was better than aseptic intermittent catheterization alone in improving response rates (RR 1.23, 95% CI 1.10 to 1.38. No severe adverse events were reported. In conclusion, acupuncture as a complementary therapy may have a potential effect in CUR due to SCI in decreasing PVR and improving bladder voiding. Additionally, acupuncture may be safe in treating CUR caused by SCI. However, due to the lack of high quality RCTs, we could not draw any definitive conclusions. More well-designed RCTs are needed to provide strong evidence.

Acute Urinary Obstruction in a Tetraplegic Patient from Misplacement of Catheter in Urethra.

A male tetraplegic patient attended accident and emergency with a blocked catheter; on removing the catheter, he passed bloody urine. After three unsuccessful attempts were made to insert a catheter by nursing staff, a junior doctor inserted a three-way Foley catheter with a 30-mL balloon but inflated the balloon with 10 mL of water to commence the bladder irrigation. The creatinine level was mostly 19 µmol/L (range: 0-135 µmol/L) but increased to 46 µmol/L on day 7. Computerized tomography urogram revealed that the bilateral hydronephrosis with hydroureter was extended down to urinary bladder, the bladder was distended, prostatic urethra was dilated and filled with urine, and although the balloon of Foley catheter was not seen in the bladder, the tip of the catheter was seen lying in the urethra. Following the re-catheterization, the creatinine level decreased to 21 µmol/L. A follow-up ultrasound scan revealed no evidence of hydronephrosis in both kidneys. Flexible cystoscopy revealed inflamed bladder mucosa, catheter reaction, and tiny stones. There was no bladder tumor. This case report concludes that the cause of bilateral hydronephrosis, hydroureter, and distended bladder was inadequate drainage of urinary bladder as the Foley balloon that was under-filled slipped into the urethra resulting in an obstruction to urine flow. Urethral catheterization in tetraplegic patients should be performed by senior, experienced staff in order to avoid trauma and incorrect positioning. Tetraplegic subjects with decreased muscle mass have low creatinine level. Increase in creatinine level (>1.5 times the basal level) indicates acute kidney injury, although peak creatinine level may still be within laboratory reference range. While scanning the urinary tract of spinal cord injury patients with indwelling urinary catheter, if Foley balloon is not seen within the bladder, urethra should be scanned to locate the Foley balloon.

Full Text Available ABSTRACT Objective: To evaluate the role of renal ultrasound (RUS and urinary IL-6 in the differentiation between acute pyelonephritis (APN and lower urinary tract infection (LUTI. Patients and methods: This prospective study was carried out at the Pediatric and urology outpatient and inpatient departments of Cairo University Children's Hospital as well as October 6 University Hospital and it included 155 children between one month and fourteen years old with positive culture UTI. Patients were categorized into APN and LUTI based on their clinical features and laboratory parameters. Thirty healthy children, age and sex matched constituted the control group. Children with positive urine cultures were treated with appropriate antibiotics. Before treatment, urinary IL-6 was measured by enzyme immunoassay technique (ELISA, and renal ultrasound (RUS was done. CRP (C-reactive protein, IL-6 and RUS were repeated on the 14th day of antibiotic treatment to evaluate the changes in their levels in response to treatment. Results: UIL-6 levels were more significantly higher in patients with APN than in patients with LUTI (24.3±19.3pg/mL for APN vs. 7.3±2.7pg/mL in LUTI (95% CI: 2.6-27.4; p20pg/mL and serum CRP >20μg/mL were highly reliable markers of APN. Mean renal volume and mean volume difference between the two kidneys in the APN group were more than that of the LUTI and control groups (P<0.001. Renal volume between 120-130% of normal was the best for differentiating APN from LUTI. Conclusions: RUS and urinary IL-6 levels have a highly dependable role in the differentiation between APN and LUTI especially in places where other investigations are not available and/ or affordable.

IMPORTANCE Asymptomatic bacteriuria and symptomatic urinary tract infections (UTIs) in older women are commonly encountered in outpatient practice. OBJECTIVE To review management of asymptomatic bacteriuria and symptomatic UTI and review prevention of recurrent UTIs in older community-dwelling women. EVIDENCE REVIEW A search of Ovid (Medline, PsycINFO, Embase) for English-language human studies conducted among adults aged 65 years and older and published in peer-reviewed journals from 1946 to November 20, 2013. RESULTS The clinical spectrum of UTIs ranges from asymptomatic bacteriuria, to symptomatic and recurrent UTIs, to sepsis associated with UTI requiring hospitalization. Recent evidence helps differentiate asymptomatic bacteriuria from symptomatic UTI. Asymptomatic bacteriuria is transient in older women, often resolves without any treatment, and is not associated with morbidity or mortality. The diagnosis of symptomatic UTI is made when a patient has both clinical features and laboratory evidence of a urinary infection. Absent other causes, patients presenting with any 2 of the following meet the clinical diagnostic criteria for symptomatic UTI: fever, worsened urinary urgency or frequency, acute dysuria, suprapubic tenderness, or costovertebral angle pain or tenderness. A positive urine culture (≥105 CFU/mL) with no more than 2 uropathogens and pyuria confirms the diagnosis of UTI. Risk factors for recurrent symptomatic UTI include diabetes, functional disability, recent sexual intercourse, prior history of urogynecologic surgery, urinary retention, and urinary incontinence. Testing for UTI is easily performed in the clinic using dipstick tests. When there is a low pretest probability of UTI, a negative dipstick result for leukocyte esterase and nitrites excludes infection. Antibiotics are selected by identifying the uropathogen, knowing local resistance rates, and considering adverse effect profiles. Chronic suppressive antibiotics for 6 to 12 months and

To determine the incidence of acute presentation of urinary calculi (UC) in Auckland, New Zealand, during the period 1999-2007, and whether there was any significant seasonal variation. The details of all UC within the population presenting acutely to public hospitals in Auckland between 1999 and 2007 were collected using clinical coding searches International Classification of Disease 10th revision (Australian Modification) N132 and N20. Climatic variables for the Auckland region were obtained from the National Institute of Water and Atmospheric Research, New Zealand. The mean atmospheric temperature, hours of sunshine and humidity data were calculated monthly for this period. During the study there were 7668 acute presentations of UC in the Auckland region. A Poisson regression model showed that the number of presentations was significantly related to temperature (P Auckland, New Zealand, varies significantly with temperature and hours of sunshine. Humidity was not a significant factor.

2011-01-01

Based on a cohort of 150 patients treated by curie-therapy for a prostate cancer, the authors report the analysis of the influence of some technical modifications (use of an automatic stepper at the beginning of a second period, and of a high frequency echographic probe during a third period) on the urinary toxicity. This toxicity has been assessed by using the urinary retention rate, and the difference between the maximum and initial International Prostate Symptom Score (IPPS). Rectal morbidity has been scaled according to a modified Radiation Therapy Oncology Group (RTOG) scale. It appears that the occurrence of urinary retention after prostate radiotherapy decreases with practice and use of the automatic stepper. It seems that there is no impact on urinary morbidity (urinary retention excluded) nor on rectal morbidity. Short communication

Urinary tracts infection (UTI) is common in children, particularly in the youngest age groups. There is a risk for progressive deterioration of renal function in these children if aggravating factors such as gross reflux and/or outflow obstruction of the urinary tract are present. In this review the pros and cons of available scintigrafic and radiological imaging techniques for the work-up of these children are presented. Ultrasound can be used in the acute phase to exclude obstruction but can not reliably show transient or permanent parenchymal lesions. The presence of reflux can be established with X-ray or direct nuclide cystography. The X-ray technique gives good morphological information and has a grading system with prognostic relevance. Both techniques are invasive and great care must be taken to keep the radiation burden down with the X-ray technique. Indirect nuclide cystography following a renographic study is non-invasive but has a lower sensitivity than direct techniques. More experience is needed with the indirect technique to evaluate the consequences of its apparently low sensitivity. Urography has a limited place in the acute work-up of urinary tract infection but can be used to look for renal scarring 1-2 years after an acute pyelonephritis. The 99m Tc dimercaptosuccinic acid (DMSA) scan can be used during the acute UTI to show pyelonephritic lesions with good accuracy and/or during the follow-up after six months to show permanent lesions. The acute DMSA scan can be omitted

A case of cystic rectal duplication (RD) is presented. A 7-day-old female was admitted with acute urinary retention, voiding difficulty, and abdominal distention since she was 4 days of age. Ultrasound and abdominal computed tomography (CT) demonstrated a huge, cystic mass in the pelvis and abdomen that resulted in acute urinary retention and bilateral hydronephrosis. CT-guided drainage of the lesion followed by transabdominal surgical excision resulted in a cure. Pathologic examination demonstrated a RD lined by respiratory epithelium.

To identify differences in acute urinary and sexual toxicity between a 6-fraction and 2-fraction high-dose-rate brachytherapy monotherapy regimen and correlate dosimetric constraints to short-term toxicity. A single institution retrospective study of 116 men with prostate cancer treated with HDR monotherapy from 2010 to 2015 was conducted. Eighty-one men had 7.25 Gy × 6-fractions and 35 men had 13.5 Gy × 2-fractions. Patients had two CT-planned implants spaced 1–2 weeks apart. Patient baseline characteristics, International Prostate Symptom Scores (IPSS) and Sexual Health Inventory for Men (SHIM) scores were collected pre-treatment and 3, 6 and 12 months post-implantation. Mixed effect modelling was undertaken to compare baseline, 1–6 month and 7–12 month scores between groups. Poisson regression analysis was performed to correlate dosimetric constraints with acute toxicity. There was no difference between baseline and post-implantation IPSS scores between 6-fraction and 2-fraction groups. SHIM scores for men treated with 6-fractions had a steeper decline at 1–6 months, but resolved at 7–12 months. Pre-treatment alpha-blocker use correlated with worse short-term acute urinary toxicity. Worsened SHIM score correlated with increasing age, diabetes mellitus and androgen-deprivation therapy. In a dosimetric analysis of outcomes, prostate V150 dose and bladder wall (D01.cc, D1cc, D2cc) dose correlated with increased IPSS score. No increased acute genitourinary or sexual dysfunction has been observed in men when transitioning from 6-fraction to 2-fraction HDR monotherapy. A dosimetric correlation was found between the V150 and bladder wall doses for acute urinary toxicity. Future research should continue to standardize and validate dose constraints for prostate HDR monotherapy patients.

To examine the impact on quality of life of recurrent acute uncomplicated urinary tract infection among premenopausal Singaporean women, and to determine the risk factors for lower quality of life among these patients. A total of 85 patients with recurrent acute uncomplicated urinary tract infection who were referred to the Urology Department at the National University Hospital, Singapore, were prospectively recruited over a 3-year period to complete the validated Short Form 36 Health Survey version 1. In addition, demographic and clinical details including symptomology and medical history were analyzed for factors impacting quality of life. Short Form 36 Health Survey version 1 results were compared with published population norms. After adjusting for age, gender and race, recurrent acute uncomplicated urinary tract infection patients had significantly lower quality of life on seven out of eight Short Form 36 Health Survey version 1 domains when compared with age-, gender- and race-adjusted population norms for Singapore. Among those with recurrent acute uncomplicated urinary tract infection, those who also reported caffeine consumption had significantly lower Short Form 36 Health Survey version 1 scores than those who did not. Those who reported chronic constipation also had consistently lower Short Form 36 Health Survey version 1 scores across all domains. Recurrent acute uncomplicated urinary tract infection has a negative impact on the quality of life of premenopausal, otherwise healthy women. Recurrent acute uncomplicated urinary tract infection patients who also have chronic constipation or consume caffeine have lower quality of life than those who do not. More studies are required to understand the relationships between these common problems and risk factors. © 2018 The Japanese Urological Association.

Guillain-Barré syndrome (GBS) as acute inflammatory demyelinating polyradiculoneuropathy frequently leads to lower urinary tract dysfunction. The available knowledge in the medical literature is limited and good recommendations for diagnosis and therapy are rare. In this study, 189 patients with GBS were screened for lower urinary tract dysfunction. In symptomatic patients, a urodynamic study was performed. Detrusor contractility, post-void residual, and changes of the symptoms over time were studied. Overall Barthel index and urinary control Barthel index as well as the relationship of time after onset of the disease and post-void residual were studied as possible screening criteria for urodynamic assessment. According to the urinary control Barthel index (BI), 115 of 189 patients (61%) presented lower urinary tract symptoms sometime during the course of disease. In 28 patients, these symptoms were temporary during the acute phase. At the time of urological assessment, 87 patients had lower urinary tract symptoms. At the end of rehabilitation, 37 had no symptoms anymore (BI 10), 20 were able to control micturition to a certain extent (BI 5), and 30 had no lower urinary tract control (BI 0). There was a significant negative correlation between post-void residual volume and overall BI (ρ -0.5823, p < 0.0001) and BI for urinary tract control (ρ -0.6430, p < 0.0001). Overall BI and BI for urinary tract control are suitable screening criteria for urodynamic assessment.

Full Text Available BACKGROUND: Urinary Kidney Injury Molecule 1 (KIM-1 is a proximal tubular injury biomarker for early detection of acute kidney injury (AKI, with variable performance characteristics depending on clinical and population settings. METHODS: Meta-analysis was performed to assess the diagnostic value of urinary KIM-1 in AKI. Relevant studies were searched from MEDLINE, EMBASE, Pubmed, Elsevier Science Direct, Scopus, Web of Science, Google Scholar and Cochrane Library. Meta-analysis methods were used to pool sensitivity and specificity and to construct summary receiver operating characteristic (SROC curves. RESULTS: A total of 2979 patients from 11 eligible studies were enrolled in the analysis. Five prospective cohorts, two cross-sectional and four case-control studies were identified for meta-analysis. The estimated sensitivity of urinary KIM-1 for the diagnosis of AKI was 74.0% (95% CI, 61.0%-84.0%, and specificity was 86.0% (95% CI, 74.0%-93.0%. The SROC analysis showed an area under the curve of 0.86(0.83-0.89. Subgroup analysis suggested that population settings and detection time were the key factors affecting the efficiency of KIM-1 for AKI diagnosis. LIMITATION: Various population settings, different definition of AKI and Serum creatinine level used as the standard might have influence on AKI diagnosis. The relatively small number of studies and heterogeneity between them also affected the evaluation. CONCLUSION: Urinary KIM-1 may be a promising biomarker for early detection of AKI with considerable predictive value, especially for cardiac surgery patients, and its potential value needs to be validated in large studies and across a broader scope of clinical settings.

Although tritium is released in large quantities into environment by nuclear industries and peaceful radioisotope utilization, its behavior is not well known. The International Atomic Energy Agency is sponsoring an international study group to obtain more information about tritiated water (HTO) behavior in different ecological systems. This paper presents the studies made on corn and beans after an acute application of tritiated water during their early stages of growth on an experimental field. Sampling and radiochemical analytical methods of tritium and its behaviour on that plants during their growth cycle are outlined. It is shown that the tritiated water retention plot has at least two components, with effective half lifes of about 10 and 100 days for corn, and 8 and 40 days for beans. (author)

Although chronic exposure to secoisolariciresinol diglycoside (SDG) was shown to alter (3)H-SDG metabolite disposition in rats, the proportion of measured radioactivity attributed to known or unknown SDG metabolites was not determined. Using HPLC and GC-MS, two experiments were conducted to determine the effect of acute (1 d) vs. chronic (10 d) SDG treatment on major urinary metabolites of (3)H-SDG in female, Sprague-Dawley rats (70-72-d-old) over a 48-h period and if new urinary metabolites were detectable in rats fed nonradioactive flaxseed or SDG. A third experiment was conducted to determine changes in postprandial blood levels of (3)H-SDG metabolites over a 24-h period with acute or chronic SDG treatment. Regardless of treatment, enterodiol, enterolactone and secoisolariciresinol accounted for 75-80% of urine radioactivity. Four potential new lignan metabolites, two of which were detected in the urine of rats fed nonradioactive flaxseed or SDG, were found. Type of treatment had no effect on levels of individual urinary metabolites of (3)H-SDG. As observed for plasma lignans in women fed flaxseed, blood radioactivity peaked at 9 h and remained high until 24 h in both treatment groups, suggesting that blood lignan kinetics might be similar with flaxseed or SDG consumption and that they were comparable between humans and rats. In conclusion, the main urinary lignan metabolites were enterodiol, enterolactone and secoisolariciresinol. Urinary composition or blood levels of radioactive lignans were not affected by the duration of SDG exposure. Thus, while chronic SDG exposure alters lignan disposition in rats, it does not change the metabolite profile.

Herpes zoster is caused by the infection of Varicella-Zoster virus. The anatomical distribution of herpes zoster in the sacral area is only 6. 9%1). Moreover, the onset rate of herpes zoster with urinary dysfunction is 0.6%1). The lesion sites of herpes zoster which cause urinary dysfunction are almost lumber and sacral areas. We describe four cases of sacral herpes zoster with urinary dysfunction in this report. All patients were elderly people (66-84 years old), and all patients were administered anti-virus drugs and alpha 1-adrenergic receptor blockers. Because of urinary retention, three patients have performed clean intermittent self-catheterization (CIC) for several weeks. As the lesions of herpes zoster healed, each patient recovered from urinary dysfunction.

A fluid-retention effect is required for beverages that are designed to prevent dehydration. That is, fluid absorbed from the intestines should not be excreted quickly; long-term retention is desirable. Here, we focused on the effect of milk protein on fluid retention, and propose a new effective oral rehydration method that can be used daily for preventing dehydration. We first evaluated the effects of different concentrations of milk protein on fluid retention by measuring the urinary volumes of rats fed fluid containing milk protein at concentrations of 1, 5, and 10%. We next compared the fluid-retention effect of milk protein-enriched drink (MPD) with those of distilled water (DW) and a sports drink (SD) by the same method. Third, to investigate the mechanism of fluid retention, we measured plasma insulin changes in rats after ingesting these three drinks. We found that the addition of milk protein at 5 or 10% reduced urinary volume in a dose-dependent manner. Ingestion of the MPD containing 4.6% milk protein resulted in lower urinary volumes than DW and SD. MPD also showed a higher water reabsorption rate in the kidneys and higher concentrations of plasma insulin than DW and SD. These results suggest that increasing milk protein concentration in a beverage enhances fluid retention, which may allow the possibility to develop rehydration beverages that are more effective than SDs. In addition, insulin-modifying renal water reabsorption may contribute to the fluid-retention effect of MPD.

Full Text Available Objective: to study the clinical and diagnostic significance of urinary neutrophil gelatinase-associated lipocalin-2 (NGAL measurement in children with urinary tract infection (я=15 and pyelonephritis (я=15. The patients' age was 1 to 16 years (mean age, 7.32+4.52 years. The diagnosis was verified on the basis of clinical and laboratory findings and medical history and instrumental examination data. Urinary NGAL levels were measured by enzyme immunoassay (a Bio\\fendor Laboratory Medicine kit and calculated with reference to mg of creatinine. Urinary NGAL levels were established to depend on the degree of renal parenchymal damage. The investigation showed a relationship between the excretion of NGAL during the acute phase of pyelonephritis and the detection of renal scarring, as evidenced by statistical DMCA nephroscintigraphy. The acute pyelonephritis group exhibited a moderate direct correlation between the renal excretion of NGAL and the degree of leukocytosis and the blood levels of C-reactive protein. The findings allow recommendations for measuring urinary NGAL levels as an additional noninvasive marker for the early detection of renal parenchymal damage.

To evaluate the role of renal ultrasound (RUS) and urinary IL-6 in the differentiation between acute pyelonephritis (APN) and lower urinary tract infection (LUTI). This prospective study was carried out at the Pediatric and urology outpatient and inpatient departments of Cairo University Children's Hospital as well as October 6 University Hospital and it included 155 children between one month and fourteen years old with positive culture UTI. Patients were categorized into APN and LUTI based on their clinical features and laboratory parameters. Thirty healthy children, age and sex matched constituted the control group. Children with positive urine cultures were treated with appropriate antibiotics. Before treatment, urinary IL-6 was measured by enzyme immunoassay technique (ELISA), and renal ultrasound (RUS) was done. CRP (C-reactive protein), IL-6 and RUS were repeated on the 14th day of antibiotic treatment to evaluate the changes in their levels in response to treatment. UIL-6 levels were more significantly higher in patients with APN than in patients with LUTI (24.3±19.3pg/mL for APN vs. 7.3±2.7pg/mL in LUTI (95% CI: 2.6-27.4; p20pg/mL and serum CRP >20μg/mL were highly reliable markers of APN. Mean renal volume and mean volume difference between the two kidneys in the APN group were more than that of the LUTI and control groups (Purinary IL-6 levels have a highly dependable role in the differentiation between APN and LUTI especially in places where other investigations are not available and/ or affordable.

It is paramount that there is an adequate nursing workforce supply for now and in the future, to achieve equitable and quality health outcomes and consumer access to healthcare, regardless of geographic location. Nursing forms the largest body of employees in the health care system, spanning all segments of care. A shortage of nurses, particularly in the acute care settings in hospitals, jeopardizes the provision of quality health care to consumers. This article provides a literature review of Australian State and Federal Government reports into nurse retention. All reports discuss staff turnover rates; the average age of nurses; enrolment numbers in nursing courses; workloads; nursing workforce shortfalls and the effect on the work environment; leadership and management styles; organizational culture; change management; the mobility of nursing qualifications both locally and internationally and the critical need to value nurses. Then why has the situation of nurse retention not improved? Possible reasons for the continued nurse shortage and the promise of strategic HRM in addressing nurse retention are discussed.

Herpes zoster infection involving the sacral dermatomes has been associated with bladder dysfunction and, although rarely, with acute urinary retention. Less than 150 cases have been reported in the literature. After reviewing our institute's chart records covering a period of time dating from 1991 to 2001, we found that three of our patients had developed acute urinary retention following herpes zoster skin lesions of the S2-4 dermatomes. Herein we report our findings. These three patients had previously been found to have normal voiding status. However, at the time of complaint urodynamic studies revealed detrusor areflexia or detrusor hyporeflexia with decreased sensation of bladder filling. After micturation recovery, repeat urodynamic studies revealed detrusor pressure and bladder sensation recovery. After one to six weeks of treatment, all three patients could void spontaneously without catheterization. We found that, when treated with antiviral medication, supportive analgesics, and temporary urinary drainage, which included urethral catheterization and suprapubic cystostomy, acute urinary retention associated with herpes zoster has a generally favorable prognosis. In other words, we found that in spite of its rarity, herpes zoster induced neuropathic bladder dysfunction is reversible when treated appropriately.

The management of urinary clot retention and hematuria involves manual irrigation with sterile water or normal saline via a Foley catheter followed by continuous bladder irrigation. Irrigation may become difficult because of the formation of dense blood clots. Tissue plasminogen activator (t-PA/Alteplase) may be a useful pharmacological agent to improve the efficacy of manual irrigation of large, dense clots. The goal of the current study was to compare t-PA to sterile water for clot irrigation in an in vitro model. In vitro models of clot retention were created using 500-cc urinary leg bags each filled with 80 cc of unpreserved whole blood from a healthy volunteer. Each model was incubated at 25 degrees C for 24 hours to allow clot formation. Four models each with 25 mL solution of t-PA at concentrations of 2, 1, 0.5, and 0.25 mg/mL were evaluated and compared to a control (25 mL sterile water). Models were instilled with solution (t-PA or control) and incubated for 30 minutes at 37 degrees C, and then irrigated with sterile water via 18F Foley by a blinded investigator. Three separate experiments were conducted, and statistical analysis was performed comparing various irrigation parameters. Clot evacuation with 25 mL of t-PA at a concentration of 2 mg/mL (50 mg) was significantly easier (p = 0.05) and faster (p < 0.05) than the sterile water control. The mean time for clot evacuation in this model was 2.7 minutes for t-PA solution 2 mg/mL versus 7.3 minutes for the control (p < 0.05). Compared to the control, irrigation with t-PA solution 2 mg/mL also required less irrigant (180 mL vs. 500 mL) (p < 0.05) for complete evacuation. There was a similar trend in efficacy for the lower doses of t-PA, but this was not statistically significant. In this in vitro study, a single 25 mL instillation of t-PA solution 2 mg/mL is significantly better than sterile water alone for clot evacuation. In vivo animal studies are pending.

A 77-year-old man with severe septic disseminated intravascular coagulation following urinary infection was transported to our hospital. He had developed urinary retention induced by untreated prostatic hyperplasia. Immediate drainage with a Foley catheter was successfully carried out, but the hematuria progressed to life-threatening hemorrhage. Complete hemostasis was impossible by surgical treatment because the tissue around the prostatic urethra was very fragile and hemorrhagic. Organized treatments (continuous hemodiafiltration combined with polymyxin-B immobilized fiber column hemoperfusion and systemic treatment with antibiotics and coagulation factors) were commenced soon after the operation. The patient eventually recovered from the septic disseminated intravascular coagulation. This case report illustrates the risk of placement of Foley catheters in patients with severe septic disseminated intravascular coagulation.

A syndrome involving acute urinary retention in combination with sacral radiculitis and cerebrospinal fluid pleocytosis was first described by the American neurosurgeon Charles Elsberg in 1931. In many instances the aetiology is herpes simplex virus type 2 (HSV-2) reactivation from sensory neurons. In this case report we present a 34-year-old pregnant woman with previous undiagnosed sensory lumbosacral symptoms. She was hospitalized with HSV-2 meningitis and lumbosacral radiculitis but no genital rash. A week after the onset of symptoms she developed acute urinary retention, thus indicating Elsberg syndrome.

Analysis of lower urinary tract disease of dogs

Full Text Available ABSTRACT: Lower urinary tract diseases (LUTD include different conditions that affect the urinary bladder, urethra and prostate. The objective of this study was to determine the frequency of different related diseases, to characterize the population affected, and to determine risk factors in dogs. The clinical cases were diagnosed with LUTD through physical examination, and clinical laboratory and imaging studies. Male dogs had a greater predisposition to present a LUTD. Dogs from 3 months to 18 years with a median of 8 years were affected, and the most affected breeds were Poodle, Labrador, German shepherd, Schnauzer, Cocker Spaniel and Chihuahua. The LUTD presented with the following frequencies: bacterial urinary tract infection 34.02%; micturition disorders 22.68%; urolithiasis 20.61%; prostatic disease 14.43%; traumatic problems 8.24%. Sixty-seven per cent of the cases were specific diseases, such as uncomplicated and complicated bacterial urinary tract infections, urinary retention of neurologic origin and silica urolithiasis.

The urinary tract infection is one of the most frequent bacterial infections in the childhood. Two hundred eleven children diagnosed as first febrile urinary tract infection patients were studied and performed Tc-DMSA renal scintigraphy in the acute phase of infection. The results were correlated to the duration and intensity of the fever before the diagnosis, to the acute phase reactants (hemogram, erythrosedimentation and reactive-C protein) and to the results of imaging studies (renal ultrasound and mictional uretrocystography)

To evaluate the efficacy and safety of tamsulosin and solifenacin combination therapy compared with tamsulosin monotherapy for male lower urinary tract symptoms (LUTS). We identified all eligible studies that compared tamsulosin and solifenacin combination therapy with tamsulosin monotherapy for male LUTS (up to January 2015). The fixed- or random-effects model was selected depending on the proportion of heterogeneity. Seven articles were identified as eligible for this meta-analysis, with a total of 3063 participants. Synthetic data showed combination therapy had significant improvements in Storage International Prostate Symptom Score (WMD = -0.60; 95% CI: -0.81 to -0.38, P tamsulosin and solifenacin combined therapy group (30.82%) was similar to the tamsulosin monotherapy group (25.75%). Acute urinary retention was seldom reported in the studies and no clinically significant changes regarding Qmax were showed in our meta-analysis. Tamsulosin and solifenacin combination therapy may be a reasonable option for male LUTS patients, especially for those who have significant storage symptoms. However, PVR should be measured during treatment to assess the increase in PVR or the incidence of AUR.

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

Urinary tract infections (UTIs) are the most common bacterial infection in pregnancy, increasing the risk of maternal and neonatal morbidity and mortality. Urinary tract infections may present as asymptomatic bacteriuria, acute cystitis or pyelonephritis. Escherichia coli is the most common pathogen associated with both symptomatic and asymptomatic bacteriuria. If asymptomatic bacteriuria is untreated, up to 30% of mothers develop acute pyelonephritis, with an increased risk of multiple maternal and neonatal complications, such as preeclampsia, preterm birth, intrauterine growth restriction and low birth weight. Urinary tract infection is a common, but preventable cause of pregnancy complications, thus urinary tests, such as urine culture or new technologies such as high-throughput DNA sequence-based analyses, should be used in order to improve antenatal screening of pregnant women.

Full Text Available Eosinophilic meningitis or encephalitis is a rare disorder and is most commonly caused by Angiostrongylus cantonensis. Humans are accidentally infected when they ingest raw snails or vegetables contaminated with the parasite larvae. Because of the improvement in sanitary food handling practices, the occurrence of A. cantonensis eosinophilic meningitis has been decreasing in Taiwan in recent decades. The common symptoms and signs of eosinophilic meningitis are severe headache, neck stiffness, paresthesia, vomiting, nausea, and fever. Acute urinary retention is a rare presentation. We report a case of A. cantonensis eosinophilic meningitis in an intellectually disabled patient who presented with acute urinary retention without any other meningeal signs. The patient received supportive treatment with corticosteroid therapy and was discharged and received urinary rehabilitation at home.

Full Text Available Urinary tract infections (UTI cause a great number of morbidity and mortality. These infections are serious complications in pregnancy, patients with diabetes, polycystic kidneys disease, sickle cell anaemia, kidney transplant and in patients with functional or structural anomalies of the urinary tract. The aim of this investigation was to determine a dominant causative agents of UTI and some of the clinical and laboratory characteristics of acute community-acquired UTI in adult hospitalised patients. We studied 200 adult patients with acute community-acquired UTI hospitalised in the Clinic for Infectious Diseases Tuzla from January 2006 to December 2007. The patients were divided into two groups: a group of patients with E. coli UTI (147 and a group of patients with non-E. coli UTI (53. In these two groups, the symptoms and signs of illness, blood test and urine analysis results were analysed. Our results have shown that the patients with E. coli UTI frequently had fever higher than 38,5 degrees C (p<0,0001, chills (p=0,0349, headache (p=0,0499, cloudy urine (p<0,0001, proteinuria (p=0,0011 and positive nitrite-test (p=0,0002. The patients with non-E. coli UTI frequently had fever lower than 38,5 degrees C (p<0,0001 and urine specific gravity <1015 (p=0,0012. There was no significant difference in blood test results between patients with E. coli and non-E. coli UTI. These clinical and laboratory findings can lead us to early etiological diagnosis of these UTI before urine culture detection of causative agents, which takes several days. Early etiological diagnosis of the E. coli and non-E. coli UTI is necessary for an urgent administration of appropriate empirical antibiotic treatment. This is very important in prevention of irreversible kidney damage, prolonged treatment, complications, as well as recidives and chronicity of the illness.

It has been reported that an increase of urinary selenium excretion may occur as a result of mercury vapor exposure. However, experimental data regarding the interaction between mercury vapor and selenium have yielded ambiguous results about the retention and elimination of selenium due to mercury vapor exposure and the decrease of selenium excretion due to mercury in the form of mercuric mercury (Hg/sup 2 +/). In this study, the authors measured urinary mercury and selenium in workers with or without exposure to mercury vapor to determine whether or not urinary selenium excretion was increased as a result of mercury vapor exposure. Urine samples were collected from 141 workers, 71 men and 70 women, whose extent of exposure to mercury vapor varied according to their job sites. Workers were divided into five groups according to their urinary mercury levels. The mercury level in group I was less than 2.8 nmol/mmol creatinine which means that this group was mostly free from mercury exposure. The average age was almost identical among the groups. For both sexes, group V (with the highest urinary mercury level) had the lowest urinary selenium level, but one-way variance analysis (ANOVA) did not reveal any significant variations of urinary selenium with urinary mercury levels; however, a weak but significant negative correlation between mercury and selenium was found in men.

Objective: To research the degression of renal function of 99 Tc m -diethylene triamine pentaaceticacid ( 99 Tc m -DTPA) renal imaging in rabbits with acute upper urinary tract obstruction and its early recovery after relief. Methods: Twenty-four health rabbit models with left acute upper urinary tract obstruction were built up. 99 Tc m -DTPA renal imaging was performed before making model and after obstruction 1, 3, 5-7 and more than 8 weeks respectively and 4 weeks after relief of obstruction. Results: After obstnrction 1 and 3 weeks, 99 Tc m -DTPA imaging showed development in left renal. Values of glomemlar filtration rate (GFR) and uptake ratio decreased, while time to reach the peak increased. These are obviously different compared with those before obstruction (t=2.916, t=7.034, P 99 Tc m -DTPA imagingshowed cortex developert. Values of GFR and uptake ratio decreased obvious, while time to reach the peak increased obviously. These are obviously different compared with those before obstruction (t=6.722, t=7.470, t=3.678, P 99 Tc m -DTPA imaging showed no obvious development. In those rabbits with durations of 1-3 weeks obstructions, the renal function could almost recover within 4 weeks after relief of obstruction. GRF is 31.23 ± 14.4 (t=2.627, P 0.05). With obstruction of 5-7 weeks, the GRF and uptake ratio, could recover partly to some extent. But with obstruction for more than 8 weeks, the renal function could not recover. Conclusions: For the acute upper urinary tract obstruction, the renal function is most remarkable decreased in the early time, and can be restored after lelief. For long time obstruction, even if relieved, the renal function is not easily to restore. The dynamic renal imaging can reflect the extent of the renal damage and its recovery, and could be used as a reliable indicator. (authors)

1. Sodium retention in disease states characterized by proteinuria, such as nephrotic syndrome, preeclampsia, and diabetic nephropathy, occurs through poorly understood mechanism(s). 2. In the nephrotic syndrome, data from experimental and clinical studies indicate that the sodium retention...... originates in the renal cortical collecting duct and involves hyper-activity of the epithelial sodium channel (ENaC). 3. The stimulus for the increased ENaC activity does not appear to involve any of the classical sodium retaining mechanisms, such as the renin-angiotensin-aldosterone system, arginine...... and diabetic nephropathy, which are also characterized by proteinuria and sodium retention. 7. In this review, we will examine the evidence for a role of urinary serine protease activity in the development of sodium and water retention in diseases characterised by proteinuria with a focus on the nephrotic...

[Urinary tract infections in pregnancy: when to treat, how to treat, and what to treat with].

Urinary tract infections (UTI) in pregnant women are a relatively frequent occurrence and the spectrum of these infections ranges from lower urinary tract disease (asymptomatic bacteriuria, acute cystitis) to upper urinary tract disease (acute pyelonephritis). Anatomical and functional changes in the urinary tract in pregnancy result in significantly higher susceptibility to progression of the infection from asymptomatic bacteriuria to the stage of acute pyelonephritis. Untreated asymptomatic bacteriuria in pregnancy leads, in as much as 40%, to the development of acute pyelonephritis with all the subsequent negative effects not only for the woman herself, but particularly for the fetus. Bacteriuria in pregnancy accounts for a significantly higher number of newborns with a low birth weight, low gestational age and higher neonatal mortality rate. Therefore, it is necessary to perform screening for bacteriuria in pregnant women and, when the finding is positive, to treat this bacteriuria. The selection of an appropriate antimicrobial agent to treat urinary tract infection in pregnancy is limited by the safety of a given drug not only for the woman, but particularly for the fetus. The article provides an overview of medications that can be safely used throughout the pregnancy or only in certain stages of pregnancy. The selection of an appropriate antibiotic should always be preceded by the result of urine culture. The article presents the principles and rules for treating asymptomatic bacteriuria, acute cystitis and acute pyelonephritis in pregnant women.

Urinary tract infections, asymptomatic bacteriuria (AB), acute cystitis (AC) and acute pyelonephritis (AP), are favored by the morphological and functional changes involved in pregnancy. AB increases the risk of preterm labor, low birth weight and AP. AB should be detected by uroculture (other methods are not sufficiently effective) and treated early. Approximately 80% of cases are caused by Escherichia coli. The risks and effectiveness of the distinct antibiotic regimens should be evaluated: fosfomycin trometamol in monotherapy or as short course therapy is safe and effective for the treatment of AB and AC. AP is the most frequent cause of hospital admission for medical reasons in pregnant women and can lead to complications in 10% of cases, putting the lives of the mother and fetus at risk. Currently outpatient treatment of AP is recommended in selected cases. Adequate follow-up of pregnant women with urinary tract infections is required due to frequent recurrence.

Thomas, Carys; Keyes, Mira; Liu, Mitchell; Moravan, Veronika

2008-01-01

Purpose: To determine whether segmental urethral dosimetry is predictive for the degree of urinary morbidity after prostate brachytherapy in patients with no urinary symptoms before prostate brachytherapy. Methods and Materials: Between May 2000 and November 2005, 1,107 patients underwent iodine-125 monotherapy with urethral sparing techniques. A total of 166 patients fulfilled the selection criteria: baseline (International Prostate Symptom Score) IPSS ≤5, no androgen deprivation therapy, and prostate ultrasound planning volumes (PUTV) <45 mL. The median follow-up was 44 months. Urinary morbidity was defined by maximum increase in IPSS, time to IPSS resolution, maximum Radiation Therapy Oncology Group (RTOG) score, time to RTOG resolution, and urinary retention. Surrogate deviated urethra was contoured and doses calculated at the base, mid-prostate, apex, and urogenital diaphragm. Univariate and multivariate analysis was used to evaluate urethral and prostate dosimetry, age, PUTV, and number of needles for their association with urinary morbidity. Results: Urethral dose was fairly constant in all urethra segments except prostate base, where the variation in does was large. On multivariate analysis, higher urethral base D50, V100, and larger PUTV were predictive for higher maximum increase in IPSS. Higher urethral base V100 and larger PUTV predicted for prolonged IPSS resolution. Higher urethral base D50 and larger needle number predicted for longer RTOG resolution. Higher urethral base V100 predicted for RTOG ≥2 toxicity. Conclusions: Radiation dose to the urethral base, larger PUTV, and needle number, predicted for increased urinary toxicity after prostate brachytherapy. Correlation between urinary morbidity and urethral base dosimetry may reflect a large variation in urethral dose observed at the prostate base

Hyperplasia of stromal and epithelial prostatic elements that surround the urethra cause lower urinary tract symptoms (LUTS, urinary tract infection, and acute urinary retention. Medical treatments of symptomatic BPH include; 1 the 5α-reductase inhibitors, 2 the α1-adrenergic antagonists, and 3 the combination of a 5α-reductase inhibitor and a α1-adrenergic antagonist. Selective α1-adrenergic antagonists relax the smooth muscle of the prostate and bladder neck without affecting the detrussor muscle of the bladder wall, thus decreasing the resistance to urine flow without compromising bladder contractility. Clinical trials have shown that α1-adrenergic antagonists decrease LUTS and increase urinary flow rates in men with symptomatic BPH, but do not reduce the long-term risk of urinary retention or need for surgical intervention. Inhibitors of 5α-reductase decrease production of dihydrotestosterone within the prostate resulting in decreased prostate volumes, increased peak urinary flow rates, improvement of symptoms, and decreased risk of acute urinary retention and need for surgical intervention. The combination of a 5α-reductase inhibitor and a α1-adrenergic antagonist reduces the clinical progression of BPH over either class of drug alone.Keywords: prostatic hyperplasia, 5α-reductase, dutasteride

Benign prostatic hyperplasia (BPH) is a frequent cause of lower urinary symptoms, with a prevalence of 50% by the sixth decade of life. Hyperplasia of stromal and epithelial prostatic elements that surround the urethra cause lower urinary tract symptoms (LUTS), urinary tract infection and acute urinary retention. Medical treatments of symptomatic BPH include; 1) the 5α-reductase inhibitors, 2) the α1-adrenergic antagonists, and 3) the combination of a 5α-reductase inhibitor and a α1-adrenergic antagonist. Selective α1-adrenergic antagonists relax the smooth muscle of the prostate and bladder neck without affecting the detrussor muscle of the bladder wall, thus decreasing the resistance to urine flow without compromising bladder contractility. Clinical trials have shown that α1-adrenergic antagonists decrease LUTS and increase urinary flow rates in men with symptomatic BPH, but do not reduce the long-term risk of urinary retention or need for surgical intervention. Inhibitors of 5α-reductase decrease production of dihydrotestosterone within the prostate resulting in decreased prostate volumes, increased peak urinary flow rates, improvement of symptoms, and decreased risk of acute urinary retention and need for surgical intervention. Interim results of the ongoing Combination of Avodart and Tamsulosin (CombAt) study have shown combination therapy with the 5α-reductase inhibitor dutasteride and the α1-adrenergic antagonist tamsulosin offer significant improvements from baseline compared with either drug alone.

Male lower urinary tract symptoms (LUTS) are common and increase in prevalence with age. Up to 90% of men aged 50 to 80 may suffer from troublesome LUTS. Men may attend expressing direct concern about micturition, describing one or more LUTS and the related impact on their quality of life. Frequently men may present for other medical or urological reasons such as concern regarding their risk of having prostate cancer or erectile dysfunction but on taking a history bothersome LUTS are identified. Men may present late in the community with urinary retention: the inability to pass urine. A thorough urological history is essential to inform management. It is important to determine whether men have storage or voiding LUTS or both. All patients must have a systematic comprehensive examination including genitalia and a digital rectal examination. Investigations performed in primary care should be guided by the history and examination findings, taking into account the impact of the LUTS on the individual's quality of life. Current NICE guidelines recommend the following to be performed at initial assessment: frequency volume chart (FVC); urine dipstick to detect blood, glucose, protein, leucocytes and nitrites; and prostate specific antigen. Men should be referred for urological review if they have: bothersome LUTS which have not responded to conservative management or medical therapy; LUTS in association with recurrent or persistent UTIs; urinary retention; renal impairment suspected to be secondary to lower urinary tract dysfunction; or suspected urological malignancy. All patients not meeting criteria for immediate referral to urology can be managed initially in primary care. Based on history, examination and investigation findings an individualised management plan should be formulated. Basic lifestyle advice should be given regarding reduction or avoidance of caffeinated products and alcohol. The FVC should guide advice regarding fluid intake management and all

Full Text Available Urinary tract infections frequently affect pregnant mothers. This problem causes significant morbidity and healthcare expenditure. Three common clinical manifestations of UTIs in pregnancy are: asymptomatic bacteriuria, acute cystitis and acute pyelonephritis. Escherichia coli remains the most frequent organism isolated in UTIs. All pregnant mothers should be screened for UTIs in pregnancy and antibiotics should be commenced without delay. Urine culture and sensitivity is the gold standard in diagnosing UTIs. Without treatment, asymptomatic bacteriuria in pregnancy is associated with preterm delivery, intrauterine growth retardation, low birth weight, maternal hypertension, pre-eclampsia and anaemia. Acute pyelonephritis can lead to maternal sepsis. Recurrent UTIs in pregnancy require prophylactic antibiotic treatment.

BackgroundWe aimed to evaluate the effectiveness of PAE in weaning of catheter and relieving obstructive urinary symptoms in patients with acute urinary retention (AUR) due to benign prostatic hypertrophy (BPH) and failed trial without catheter (TWOC).Materials and MethodsIn this prospective study approved by the institutional review board, a signed informed consent was obtained. Eighteen consecutive patients with AUR due to BPH and failed TWOC were recruited. Nineteen consecutive patients with BPH but without AUR were recruited as a control. Patients with CTA evidence of arterial occlusion or significant stenosis along the prostate artery access path were excluded. PAE was performed using microspheres (100–300 μm diameter). Outcome assessment included successful weaning of catheter in 2 weeks, procedure-related complications, change of symptomatology and urodynamic findings at 1 month as compared to baseline, percent non-perfused prostate volume, and prostate volume reduction on MRI at 2 weeks.ResultsTwo patients in the study group and four in the control group were excluded due to arterial pathology. Embolization of bilateral prostate arteries was achieved in all patients in both the groups (100%). There was no complication. The catheter was successfully weaned in 87.5% (14/16) of patients within 14 days in the treatment group. There was no significant difference in patient demographics, prostate characteristics, and all outcome assessment parameters between both the groups.ConclusionsPAE was probably safe and effective in weaning of catheter and relieving obstructive urinary symptoms in patients due to BPH, with treatment outcomes comparable to those without AUR.

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

Using IGFBP7 and TIMP-2 for early detection of cellular kidney injury, thus allowing the early initiation of renal protection measures, may represent a new concept of evaluating renal function.In this prospective study, urinary [TIMP-2]×[IGFBP7] was measured in surgical patients at high risk for AKI. A predefined cut-off value of [TIMP-2]×[IGFBP7] >0.3 was used for assessing diagnostic accuracy. Perioperative characteristics were evaluated, and ROC analyses as well as logistic regression models of risk assessment were calculated with and without a [TIMP-2]×[IGFBP7] test.107 patients were included in the study, of whom 45 (42% developed AKI. The highest median values of biomarker were detected in septic, transplant and patients after hepatic surgery (1.24 vs 0.45 vs 0.47 ng/l²/1000. The area under receiving operating characteristic curve (AUC for the risk of any AKI was 0.85, for early use of RRT 0.83 and for 28-day mortality 0.77. In a multivariable model with established perioperative risk factors, the [TIMP-2]×[IGFBP7] test was the strongest predictor of AKI and significantly improved the risk assessment (p<0.001.Urinary [TIMP-2]×[IGFBP7] test sufficiently detect patients with risk of AKI after major non-cardiac surgery. Due to its rapid responsiveness it extends the time frame for intervention to prevent development of AKI.

Purpose: To evaluate the acute toxicities of hypofractionated accelerated radiotherapy (RT) using a concomitant intensity-modulated RT boost in conjunction with elective pelvic nodal irradiation for high-risk prostate cancer. Methods and Materials: This report focused on 66 patients entered into this prospective Phase I study. The eligible patients had clinically localized prostate cancer with at least one of the following high-risk features (Stage T3, Gleason score ≥8, or prostate-specific antigen level >20 ng/mL). Patients were treated with 45 Gy in 25 fractions to the pelvic lymph nodes using a conventional four-field technique. A concomitant intensity-modulated radiotherapy boost of 22.5 Gy in 25 fractions was delivered to the prostate. Thus, the prostate received 67.5 Gy in 25 fractions within 5 weeks. Next, the patients underwent 3 years of adjuvant androgen ablative therapy. Acute toxicities were assessed using the Common Terminology Criteria for Adverse Events, version 3.0, weekly during treatment and at 3 months after RT. Results: The median patient age was 71 years. The median pretreatment prostate-specific antigen level and Gleason score was 18.7 ng/L and 8, respectively. Grade 1-2 genitourinary and gastrointestinal toxicities were common during RT but most had settled at 3 months after treatment. Only 5 patients had acute Grade 3 genitourinary toxicity, in the form of urinary incontinence (n = 1), urinary frequency/urgency (n = 3), and urinary retention (n = 1). None of the patients developed Grade 3 or greater gastrointestinal or Grade 4 or greater genitourinary toxicity. Conclusion: The results of the present study have indicated that hypofractionated accelerated RT with a concomitant intensity-modulated RT boost and pelvic nodal irradiation is feasible with acceptable acute toxicity

Temporary electrical stimulation using anal or vaginal electrodes and an external pulse generator has been a treatment modality for urinary urge incontinence for nearly three decades. In 1981 Tanagho and Schmidt introduced chronic electrical stimulation of the sacral spinal nerves using a permanently implanted sacral foramen electrode and a battery powered pulse generator for treatment of different kinds of lower urinary tract dysfunction, refractory to conservative treatment. At our department chronic unilateral electrical stimulation of the S3 sacral spinal nerve has been used for treatment of vesi-courethral dysfunction in 43 patients with a mean postoperative follow up of 43,6 months. Lasting symptomatic improvement by more than 50 % could be achieved in 13 of 18 patients with motor urge incontinence (72,2 %) and in 18 of the 21 patients with urinary retention (85,7 %). Implants offer a sustained therapeutic effect to treatment responders, which is not achieved by temporary neuromodulation. Chronic neuromodulation should be predominantly considered in patients with urinary retention. Furthermore in patients with motor urge incontinence, refusing temporary techniques or in those requiring too much effort to achieve a sustained clinical effect. Despite high initial costs chronic sacral neuromodulation is an economically reasonable treatment option in the long run, when comparing it to the more invasive remaining therapeutic alternatives.

Despite its proximity to the fecal flora, the urinary tract is considered sterile. The precise mechanisms by which the urinary tract maintains sterility are not well understood. Host immune responses are critically important in the antimicrobial defense of the urinary tract. During recent years, considerable advances have been made in our understanding of the mechanisms underlying immune homeostasis of the kidney and urinary tract. Dysfunctions in these immune mechanisms may result in acute disease, tissue destruction and overwhelming infection. The objective of this review is to provide an overview of the innate immune response in the urinary tract in response to microbial assault. In doing so, we focus on the role of antimicrobial peptides-a ubiquitous component of the innate immune response.

Radionuclide targeting with particular emphasis on urinary bladder carcinoma

International Nuclear Information System (INIS)

The incidence of urinary bladder carcinoma is increasing and many patients die every year of this disease despite assumed radical therapy. Thus, there is a need for improved methods of diagnosis and therapy. Radionuclide targeting is based on achieving specific delivery of radioactive nuclides to tumour cells with minimal damage to surrounding normal tissues. Two possible target structures are the epidermal growth factor (EGF) receptor and the related receptor HER-2. Cellular binding and retention of 125 I-EGF-dextran conjugates was investigated in two bladder carcinoma cell lines. The conjugate bound specifically to the EGF receptor with delayed maximum binding, limited intracellular degradation and prolonged cellular retention compared to 125 I-EGF. EGF was labelled using different radionuclides and methods. All the labelled variants bound specifically to the tumour cells although the cellular binding patterns and retention varied considerably. 111 In-DTPA-EGF had highest cellular retention and in decreasing order 211 At-benzoyl-EGF and 125 I-labelled EGF. Bladder cancer spheroids bound both 125 I-EGF-dextran as well as 125 I-EGF. Conjugate binding increased during a 48 h incubation period and was most prominent in the outer cell layers. The length of the dextran chain appeared not to alter the binding pattern. The expression of EGF receptors and HER-2 in metastases and primary bladder carcinoma tumours was investigated. Both receptors were expressed in the majority of metastases and primary tumours. Targeting the EGF receptor and/or HER-2 in urinary bladder carcinoma is an exciting new concept

Urinary infections are a common type of pediatric disease, and their treatment and prognosis are closely correlated with infection location. Common clinical manifestations and laboratory tests are insufficient to differentiate between acute pyelonephritis and lower urinary tract infection. This study was conducted to explore a diagnostic method for upper and lower urinary tract infection differentiation. The diagnostic values of procalcitonin (PCT) and C-reactive protein (CRP) were analyzed using the receiver operating characteristic curve method for upper and lower urinary tract infection differentiation. PCT was determined using chemiluminescent immunoassay. The PCT and CRP values in children with acute pyelonephritis were significantly higher than those in children with lower urinary tract infection (3.90 ± 3.51 ng/ml and 68.17 ± 39.42 mg/l vs. 0.48 ± 0.39 ng/ml and 21.39 ± 14.92 mg/l). The PCT values were correlated with the degree of renal involvement, whereas the CRP values failed to show such a significant correlation. PCT had a sensitivity of 90.47% and a specificity of 88% in predicting nephropathia, whereas CRP had sensitivity of 85.71% and a specificity of 48%. Both PCT and CRP can be used for upper and lower urinary tract infection differentiation, but PCT has higher sensitivity and specificity in predicting pyelonephritis than CRP. PCT showed better results than CRP. PCT values were also correlated with the degree of renal involvement.

Background: Urine exosomes, vesicles exocytosed into urine by all renal epithelial cell types, occur under normal physiologic and disease states. Exosome contents may mirror disease-specific proteome perturbations in kidney injury. Analysis methodologies for the exosomal fraction of the urinary proteome were developed and for comparing the urinary exosomal fraction versus unfractionated proteome for biomarker discovery. Methods: Urine exosomes were isolated by centrifugal filtration from mid-stream, second morning void, urine samples collected from kidney transplant recipients with and without biopsy matched acute rejection. The proteomes of unfractionated whole urine (Uw) and urine exosomes (Uexo) underwent mass spectrometry-based quantitative proteomics analysis. The proteome data were analyzed for significant differential protein abundances in acute rejection (AR). Results: Identifications of 1018 and 349 proteins, Uw and Uexo fractions, respectively, demonstrated a 279 protein overlap between the two urinary compartments with 25%(70) of overlapping proteins unique to Uexoand represented membrane bound proteins (p=9.31e-7). Of 349 urine exosomal proteins identified in transplant patients 220 were not previously identified in the normal urine exosomal fraction. Uexo proteins (11), functioning in the inflammatory / stress response, were more abundant in patients with biopsy-confirmed acute rejection, 3 of which were exclusive to Uexo. Uexo AR-specific biomarkers (8) were also detected in Uw, but since they were observed at significantly lower abundances in Uw, they were not significant for AR in Uw. Conclusions: A rapid urinary exosome isolation method and quantitative measurement of enriched Uexo proteins was applied. Urine proteins specific to the exosomal fraction were detected either in unfractionated urine (at low abundances) or by Uexo fraction analysis. Perturbed proteins in the exosomal compartment of urine collected from kidney transplant patients were

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

Between 1985 and 1987 102 children, age 0-14 years, presented with a first acute symptomatic E. coli urinary tract infection. Investigations included early 99m technetium dimercaptosuccinic acid (DMSA) scan, ultrasonography, micturating cysto-urethrography and indirect voiding radionuclide cystography using 99m Tc DTPA. Follow-up DMSA scan was carried out after 6 months. Twenty-one of 102 of initial DMSA studies showed diminished uptake of radionuclide and 12 showed cortical scarring. Twenty-nine patients had significant vesicoureteral relux. The finding of diminished uptake on the initial scan was significantly associated with fever, systemic upset, length of symptoms and a peripheral blood leucocytosis. In addition the finding was associated with fever and loin pain in the older child. Both diminished uptake and scarring were more common in refluxing kidney units. We propose that, in children with UTI, diminished uptake on early DMSA scan localises infection in the renal parenchyma

To analyze the related influencing factors of urinary tract infection in patients undergoing transurethral resection of the prostate (TURP). A total of 343 patients with benign prostatic hyperplasia admitted to this hospital from January 2013 to December 2016, were selected and treated by TURP. Patients were divided into infection group and non-infection group according to the occurrence of urinary tract infection after operation. The possible influencing factors were collected to perform univariate and multivariate logistic regression analysis. There were 53 cases with urinary tract infection after operation among 343 patients with benign prostatic hyperplasia, accounting for 15.5%. The univariate analysis displayed that the occurrence of urinary tract infection in patients undergoing TURP was closely associated with patient's age ≥ 65 years old, complicated diabetes, catheterization for urinary retention before operation, no use of antibiotics before operation and postoperative indwelling catheter duration ≥ 5 d (p urinary tract infection in patients receiving TURP (p urinary tract infection after TURP, while preoperative prophylactic utilization of anti-infective drugs can reduce the occurrence of postoperative urinary tract infection.

Acute exposure of part of the skin to cold stimuli can evoke urinary urgency, a phenomenon termed acute cold-induced urgency (ACIU). Despite its high prevalence, particularly in patients with overactive bladder, little is known about the mechanisms that induce ACIU. To develop an animal model of ACIU and test the involvement of cold-activated ion channels transient receptor potential (TRP) M8 and TRPA1. Intravesical pressure and micturition were monitored in female mice (wild-type C57BL/6J, Trpa1(-/-), Trpm8(+/+), and Trpm8(-/-)) and Sprague Dawley rats. An intravesical catheter was implanted. Localized cooling of the skin was achieved using a stream of air or topical acetone. The TRPM8 antagonist (N-(3-aminopropyl)-2-{[(3-methylphenyl) methyl]oxy}-N-(2-thienylmethyl)benzamide (AMTB) or vehicle was injected intraperitoneally. Frequencies of bladder contractions and voids in response to sensory stimuli were compared using the Mann-Whitney or Kruskal-Wallis test. Brief, innocuously cold stimuli applied to different parts of the skin evoked rapid bladder contractions and voids in anesthetized mice and rats. These responses were strongly attenuated in Trpm8(-/-) mice and in rats treated with AMTB. As rodent bladder physiology differs from that of humans, it is difficult to directly extrapolate our findings to human patients. Our findings indicate that ACIU is an evolutionarily conserved reflex rather than subconscious conditioning, and provide a useful in vivo model for further investigation of the underlying mechanisms. Pharmacological inhibition of TRPM8 may be useful for treating ACIU symptoms in patients. Brief cold stimuli applied to the skin can evoke a sudden desire to urinate, which can be highly bothersome in patients with overactive bladder. We developed an animal model to study this phenomenon, and found that it depends on a specific molecular cold sensor, transient receptor potential M8 (TRPM8). Pharmacological inhibition of TRPM8 may alleviate acute cold

Full Text Available Muco-cutaneous bleeding is a common presenting feature of acute leukemias. Mucosal bleeding usually manifests as gum bleeding and/or epistaxis but may occur in any mucosal surface of the body. Hematuria as an isolated or main presenting feature of acute leukemia is rare. We describe two cases of acute leukemia, a 19 year old male with acute lymphoblastic leukemia and a 52 year old male with acute myeloid leukemia, both presenting with gross hematuria. There was no demonstrable leukemic infiltration of the urinary tract on imaging studies. Hematuria in these patients was likely to be due to occult leukemic infiltration of the urinary system, aggravated by thrombocytopenia, as it subsided after starting chemotherapy. Our cases highlight that hematuria should be remembered as a rare presenting feature of acute leukemia.

Urinary tract infections (UTIs) are infectious diseases that commonly occur in communities. Although several international guidelines for the management of UTIs have been available, clinical characteristics, etiology and antimicrobial susceptibility patterns may differ from country to country. This work represents an update of the 2011 Korean guideline for UTIs. The current guideline was developed by the update and adaptation method. This clinical practice guideline provides recommendations for the diagnosis and management of UTIs, including asymptomatic bacteriuria, acute uncomplicated cystitis, acute uncomplicated pyelonephritis, complicated pyelonephritis related to urinary tract obstruction, and acute bacterial prostatitis. This guideline targets community-acquired UTIs occurring among adult patients. Healthcare-associated UTIs, catheter-associated UTIs, and infections in immunocompromised patients were not included in this guideline. PMID:29637759

The aim of this study was to develop and validate an insurance claims-based algorithm for identifying urinary retention (UR) in epilepsy patients receiving antiepileptic drugs to facilitate safety monitoring. Data from the HealthCore Integrated Research Database(SM) in 2008-2011 (retrospective) and 2012-2013 (prospective) were used to identify epilepsy patients with UR. During the retrospective phase, three algorithms identified potential UR: (i) UR diagnosis code with a catheterization procedure code; (ii) UR diagnosis code alone; or (iii) diagnosis with UR-related symptoms. Medical records for 50 randomly selected patients satisfying ≥1 algorithm were reviewed by urologists to ascertain UR status. Positive predictive value (PPV) and 95% confidence intervals (CI) were calculated for the three component algorithms and the overall algorithm (defined as satisfying ≥1 component algorithms). Algorithms were refined using urologist review notes. In the prospective phase, the UR algorithm was refined using medical records for an additional 150 cases. In the retrospective phase, the PPV of the overall algorithm was 72.0% (95%CI: 57.5-83.8%). Algorithm 3 performed poorly and was dropped. Algorithm 1 was unchanged; urinary incontinence and cystitis were added as exclusionary diagnoses to Algorithm 2. The PPV for the modified overall algorithm was 89.2% (74.6-97.0%). In the prospective phase, the PPV for the modified overall algorithm was 76.0% (68.4-82.6%). Upon adding overactive bladder, nocturia and urinary frequency as exclusionary diagnoses, the PPV for the final overall algorithm was 81.9% (73.7-88.4%). The current UR algorithm yielded a PPV > 80% and could be used for more accurate identification of UR among epilepsy patients in a large claims database. Copyright © 2016 John Wiley & Sons, Ltd.

Full Text Available Abstract Background Image-guided radiotherapy (IGRT increases the accuracy of treatment delivery through daily target localisation. We report on toxicity symptoms experienced during radiotherapy treatment, with and without IGRT in prostate cancer patients treated radically. Methods Between 2006 and 2009, acute toxicity data for ten symptoms were collected prospectively onto standardized assessment forms. Toxicity was scored during radiotherapy, according to the Common Terminology Criteria Adverse Events V3.0, for 275 prostate cancer patients before and after the implementation of a fiducial marker IGRT program and dose escalation from 74Gy in 37 fractions, to 78Gy in 39 fractions. Margins and planning constraints were maintained the same during the study period. The symptoms scored were urinary frequency, cystitis, bladder spasm, urinary incontinence, urinary retention, diarrhoea, haemorrhoids, proctitis, anal skin discomfort and fatigue. Analysis was conducted for the maximum grade of toxicity and the median number of days from the onset of that toxicity to the end of treatment. Results In the IGRT group, 14228 toxicity scores were analysed from 249 patients. In the non-IGRT group, 1893 toxicity scores were analysed from 26 patients. Urinary frequency ≥G3 affected 23% and 7% in the non-IGRT and IGRT group respectively (p = 0.0188. Diarrhoea ≥G2 affected 15% and 3% of patients in the non-IGRT and IGRT groups (p = 0.0174. Fatigue ≥G2 affected 23% and 8% of patients in the non-IGRT and IGRT groups (p = 0.0271. The median number of days with a toxicity was higher for ≥G2 (p = 0.0179 and ≥G3 frequency (p = 0.0027, ≥G2 diarrhoea (p = 0.0033 and ≥G2 fatigue (p = 0.0088 in the non-IGRT group compared to the IGRT group. Other toxicities were not of significant statistical difference. Conclusions In this study, prostate cancer patients treated radically with IGRT had less severe urinary frequency, diarrhoea and fatigue during treatment

Tissue distribution of the radionuclides were found in the groups given the chronic exposure. Under chronic exposure to 60 Co, 109 Cd, and 137 Cs, quail rapidly accumulated these radioisotopes and the respective body burden concentrations began to level off after 11, 21, and 21 days of exposure. The biological half-lives for radioisotopes accumulated during the chronic feedings were 13 days for 60 Co, 8 days for 109 Cd, and 11 days for 137 Cs. In contrast, biological half-lives for these radioisotopes under acute feeding conditions (single four-hour feeding) were 15 days for 60 Co, 3 days for 109 Cd, and 10 days for 137 Cs. These results indicate that food chain behavior of 60 Co and 137 Cs in Bobwhite is similar following either acute or chronic exposure to contaminated food. For 109 Cd, biological retention in Bobwhite was longer under chronic exposure conditions. (U.S.)

Urinary tract infection (UTI) in children may be associated with long-term complications that could be prevented by prompt treatment. To determine the prevalence of UTI in acutely ill children ≤ 5 years presenting in general practice and to explore patterns of presenting symptoms and urine sampling strategies. Prospective observational study with systematic urine sampling, in general practices in Wales, UK. In total, 1003 children were recruited from 13 general practices between March 2008 and July 2010. The prevalence of UTI was determined and multivariable analysis performed to determine the probability of UTI. Out of 597 (60.0%) children who provided urine samples within 2 days, the prevalence of UTI was 5.9% (95% confidence interval [CI] = 4.3% to 8.0%) overall, 7.3% in those UTI (P = 0.64; P = 0.69, respectively). The probability of UTI in children aged ≥3 years without increased urinary frequency or dysuria was 2%. The probability of UTI was ≥5% in all other groups. Urine sampling based purely on GP suspicion would have missed 80% of UTIs, while a sampling strategy based on current guidelines would have missed 50%. Approximately 6% of acutely unwell children presenting to UK general practice met the criteria for a laboratory diagnosis of UTI. This higher than previously recognised prior probability of UTI warrants raised awareness of the condition and suggests clinicians should lower their threshold for urine sampling in young children. The absence of fever or presence of an alternative source of infection, as emphasised in current guidelines, may not rule out UTI in young children with adequate certainty.

Hyperammonemia usually results from an inborn error of metabolism or from an advanced liver disease. Individual case reports suggest that both distal renal tubular acidosis and urinary tract infection may also result in hyperammonemia. A systematic review of the literature on hyperammonemia secondary to distal renal tubular acidosis and urinary tract infection was conducted. We identified 39 reports on distal renal tubular acidosis or urinary tract infections in association with hyperammonemia published between 1980 and 2017. Hyperammonemia was detected in 13 children with distal renal tubular acidosis and in one adult patient with distal renal tubular acidosis secondary to primary hyperparathyroidism. In these patients a negative relationship was observed between circulating ammonia and bicarbonate levels (P urinary tract infection was complicated by acute hyperammonemia and symptoms and signs of acute neuronal dysfunction, such as an altered level of consciousness, convulsions and asterixis, often associated with signs of brain edema, such as anorexia and vomiting. Urea-splitting bacteria were isolated in 28 of the 31 cases. The urinary tract was anatomically or functionally abnormal in 30 of these patients. This study reveals that both altered distal renal tubular acidification and urinary tract infection may be associated with relevant hyperammonemia in both children and adults.

Based on a cohort of 150 patients treated by curie-therapy for a prostate cancer, the authors report the analysis of the influence of some technical modifications (use of an automatic stepper at the beginning of a second period, and of a high frequency echographic probe during a third period) on the urinary toxicity. This toxicity has been assessed by using the urinary retention rate, and the difference between the maximum and initial International Prostate Symptom Score (IPPS). Rectal morbidity has been scaled according to a modified Radiation Therapy Oncology Group (RTOG) scale. It appears that the occurrence of urinary retention after prostate radiotherapy decreases with practice and use of the automatic stepper. It seems that there is no impact on urinary morbidity (urinary retention excluded) nor on rectal morbidity. Short communication

to analyse the association between urinary incontinence and maternal weight, and its variations in pregnancy and post partum. observational study of a cohort of women from the start of pregnancy until six months post partum. Hospital San Pedro in La Rioja, Spain. 402 pregnant women without urinary incontinence at the start of pregnancy. the dependent variable was urinary incontinence, assessed using the Urogenital Distress Inventory-Short Form questionnaire. The main independent variables were body mass index (BMI) at the first antenatal visit and six months post partum, weight gain during pregnancy, postpartum weight loss, and weight retained from the start of pregnancy to six months post partum. The association between urinary incontinence and the main independent variables was measured using Student's t-test. Three simple logistic regression models were used to assess the strength of this association, one for each of the independent variables that showed a significant association with urinary incontinence (p<0.05), and three multiple regression models that included the possible variable effect modifiers were also used. At the start of pregnancy, 20.1% of the women were overweight and 8.7% were obese. Six months post partum, 30.3% of the women were overweight and 11.4% were obese. The mean (±standard deviation) retained weight was 2 (±3.1) kg. Postpartum urinary incontinence was associated with BMI at six months post partum, postpartum weight loss and retained weight at six months post partum (p<0.05). The association of urinary incontinence with these variables was significant, and remained stable in both simple and multiple regression analyses with BMI at six months post partum [odds ratio (OR) 1.09 versus 1.08], weight loss from delivery to six months post partum (OR 0.88 versus 0.88), and retained weight from the beginning of pregnancy until six months post partum (OR 1.23 versus 1.19). high BMI and weight retention at six months post partum increase the

AIM: To undertake a meta-analysis on the value of urinary trypsinogen activation peptide (uTAP) in predicting severity of acute pancreatitis on admission. METHODS: Major databases including Medline, Embase, Science Citation Index Expanded and the Cochrane Central Register of Controlled Trials in the Cochrane Library were searched to identify all relevant studies from January 1990 to January 2013. Pooled sensitivity, specificity and the diagnostic odds ratios (DORs) with 95%CI were calculated for each study and were compared to other systems/biomarkers if mentioned within the same study. Summary receiver-operating curves were conducted and the area under the curve (AUC) was evaluated. RESULTS: In total, six studies of uTAP with a cut-off value of 35 nmol/L were included in this meta-analysis. Overall, the pooled sensitivity and specificity of uTAP for predicting severity of acute pancreatitis, at time of admission, was 71% and 75%, respectively (AUC = 0.83, DOR = 8.67, 95%CI: 3.70-20.33). When uTAP was compared with plasma C-reactive protein, the pooled sensitivity, specificity, AUC and DOR were 0.64 vs 0.67, 0.77 vs 0.75, 0.82 vs 0.79 and 6.27 vs 6.32, respectively. Similarly, the pooled sensitivity, specificity, AUC and DOR of uTAP vs Acute Physiology and Chronic Health Evaluation II within the first 48 h of admission were found to be 0.64 vs 0.69, 0.77 vs 0.61, 0.82 vs 0.73 and 6.27 vs 4.61, respectively. CONCLUSION: uTAP has the potential to act as a stratification marker on admission for differentiating disease severity of acute pancreatitis. PMID:23901239

To provide an update of the definition, epidemiology, clinical presentation, investigation, treatment, and prevention of recurrent urinary tract infections in women. Continuous antibiotic prophylaxis, post-coital antibiotic prophylaxis, and acute self-treatment are all efficient alternatives to prevent recurrent urinary tract infection. Vaginal estrogen and cranberry juice can also be effective prophylaxis alternatives. A search of PubMed and The Cochrane Library for articles published in English identified the most relevant literature. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. There were no date restrictions. This update is the consensus of the Sub-Committee on Urogynaecology of the Society of Obstetricians and Gynaecologists of Canada. Recommendations were made according to the guidelines developed by the Canadian Task Force on Preventive Health Care (Table 1). Recurrent urinary tract infections need careful investigation and can be efficiently treated and prevented. Different prophylaxis options can be selected according to each patient's characteristics.

Leprosy is an infectious disease caused by Mycobacterium leprae that affects the skin and nerves. Although curable with multidrug therapy, leprosy is complicated by acute inflammatory episodes called reactions, which are the major causes of irreversible neuropathy in leprosy that occur before, during, and even after treatment. Early diagnosis and prompt treatment of reactions reduces the risk of permanent disability. This exploratory study investigated whether urinary metabolic profiles could be identified that correlate with early signs of reversal reactions (RR). A prospective cohort of leprosy patients with and without reactions and endemic controls was recruited in Nepal. Urine-derived metabolic profiles were measured longitudinally. Thus, a conventional area of biomarker identification for leprosy was extended to non-invasive urine testing. It was found that the urinary metabolome could be used to discriminate endemic controls from untreated patients with mycobacterial disease. Moreover, metabolic signatures in the urine of patients developing RR were clearly different before RR onset compared to those at RR diagnosis. This study indicates that urinary metabolic profiles are promising host biomarkers for the detection of intra-individual changes during acute inflammation in leprosy and could contribute to early treatment and prevention of tissue damage.

Short-term trials have demonstrated the efficacy and safety of combination therapy using antimuscarinics and α-blockers in men with lower urinary tract symptoms (LUTS). The Study of Solifenacin Succinate and Tamsulosin Hydrochloride OCAS (oral controlled absorption system) in Males with Lower Urinary Tract Symptoms (NEPTUNE) II is the first long-term study using solifenacin (Soli) and the oral controlled absorption system formulation of tamsulosin (TOCAS). To evaluate long-term (up to 52 wk) safety and efficacy of flexible dosing of two fixed-dose combinations (FDC) of Soli plus TOCAS in men with moderate to severe storage symptoms and voiding symptoms. Patients with both storage and voiding LUTS, maximum urinary flow rate of 4.0-12.0 ml/s, prostate size storage and voiding subscores, micturition diary variables, and quality of life parameters. In all, 1066 men completed NEPTUNE and received one dose or more of study medication in NEPTUNE II. Treatment-emergent adverse events were reported in 499 (46.8%) patients who participated in NEPTUNE II; most were mild or moderate. Urinary retention occurred in 13 of 1208 (1.1%) patients receiving one or more FDCs in NEPTUNE and/or NEPTUNE II; 8 (0.7%) required catheterisation (acute urinary retention [AUR]). Reductions in total IPSS and TUFS during NEPTUNE were maintained for up to 52 wk of FDC treatment, with mean reductions of 9.0 (standard deviation [SD]: 5.7) and 10.1 (SD: 9.2), respectively, from baseline to end of treatment. Clinically relevant improvements were also observed for secondary efficacy end points. Long-term treatment with FDC Soli plus TOCAS was well tolerated and efficacious in men with storage and voiding LUTS, with a low incidence of AUR. Treatment with solifenacin plus tamsulosin in a fixed-dose combination tablet was well tolerated by men with lower urinary tract symptoms. Improvements in symptoms were achieved after 4 wk of treatment, with further improvements at week 16 maintained for up to 52 wk

Voiding dysfunction is a rare but important complication of lumbo-sacral herpes zoster. Although the symptoms are transient, the clinical impact on immunocompromised patients cannot be overlooked. To clarify the time course of voiding dysfunction in herpes zoster, 13 herpes zoster patients with voiding dysfunction were retrospectively analyzed. Of 13 patients, 12 had background disease, and six of these were hematopoietic malignancies; four of these patients were hematopoietic stem cell transplant (HSCT) recipients. Ten patients had sacral lesions, two had lumbar, and one had thoracic lesions. Interestingly, patients with severe rash, or with hematopoietic malignancy had later onset of urinary retention than did patients with mild skin symptoms (Mann-Whitney U analysis, P = 0.053) or with other background disease (P = 0.0082). Patients with severe skin rash also had longer durations (P = 0.035). In one case, acute urinary retention occurred as late as 19 days after the onset of skin rash. In immune compromised subjects, attention should be paid to patients with herpes zoster in the lumbo-sacral area for late onset of acute urinary retention even after the resolution of skin symptoms.

Urinary catecholamines in patients with acute stroke, in reference to CT scan findings

The amount of norepinephrine (NE) and epinephrine (E) in the urine of 160 stroke patients were measured both at the acute stage and at the chronic stage (31 days or later) of the diseases and a CT scan was taken simultaneously. The urinary NE and E were separated by the high performance liquid chromatography and measured by trihydroxyindole method. Forty five healthy subjects were employed as a control group. The results were as follows: 1) In subarachnoid hemorrhage and intracerebral hemorrhage the NE and E and in cerebral infarction the NE were significantly increased in the acute stage. But, when divided by CT scan findings, the group of intracerebral hemorrhage without perforation into the ventricles showed increases of NE only and those without deviation of midline showed no significant increase of the NE and E. In cases of large cerebral infarction, both NE and E were significantly increased. It is supposed that not only the type of the disease but also the facfors such as its size, perforation into the ventricles and deviation of the midline may change activities of secretion of NE and E. 2) The NE/E ratio was significantly low in the group of intracerebral hemorrhage with perforation into the ventricles (p < 0.001) and the ratio was significantly lower in the thalamic hemorrhage than in the putaminal hemorrhage (p < 0.02). The rate of perforation into the ventricles was significantly higher in the thalamic hemorrhage (78.6 %) than that of the putaminal hemorrhage (10.5 %). 3) In the chronic stage of the stroke, the NE and E (especially E) were decreased and showed a high NE/E. ratio.

Full Text Available Purpose Clean intermittent self-catheterization (CISC is now considered the gold standard for the management of urinary retention. In the literature, several articles on patients’ perspectives on CISC and adherence to this technique have been published. No studies have yet explored the points of view of professional caregivers, such as nurses and doctors. The aim of this study was to explore the opinions of urologists about CISC and to evaluate the need for dedicated nurses specialized in CISC through a self-administered questionnaire. Methods A questionnaire was developed to explore the opinions of professional caregivers about self-catheterization and to evaluate the need to provide nurses with specialized education in CISC. Questionnaires were sent to 244 urologists through email. We received 101 completed questionnaires. The response rate was 41.4%. Results Hand function, the presence or absence of tremor, and visual acuity were rated as the most important determinants for proposing CISC to a patient. Twenty-five percent of the urologists reported that financial remuneration would give them a greater incentive to propose CISC. The lack of dedicated nurses was reported by half of the urologists as a factor preventing them from proposing CISC. A meaningful number of urologists thought that patients perceive CISC as invasive and unpleasant. Although most urologists would choose CISC as a treatment option for themselves, almost 1 urologist out of 5 would prefer a permanent catheter. Conclusions This questionnaire gave valuable insights into urologists’ perceptions of CISC, and could serve as the basis for a subsequent broader international study. Further research should also focus on the opinions of nurses and other caregivers involved in incontinence management. Apart from financial remuneration, it is also clear that ensuring sufficient expertise and time for high-quality CISC care is important. This could be a potential role for dedicated

Full Text Available Background. Cell therapy for heart disease has been proven safe and efficacious, despite poor cell retention in the injected area. Improving cell retention is hypothesized to increase the treatment effect. In the present study, human adipose-derived stromal cells (ASCs were delivered in an in situ forming alginate hydrogel following acute myocardial infarction (AMI in rats. Methods. ASCs were transduced with luciferase and tested for ASC phenotype. AMI was inducted in nude rats, with subsequent injection of saline (controls, 1 × 106 ASCs in saline or 1 × 106 ASCs in 1% (w/v alginate hydrogel. ASCs were tracked by bioluminescence and functional measurements were assessed by magnetic resonance imaging (MRI and 82rubidium positron emission tomography (PET. Results. ASCs in both saline and alginate hydrogel significantly increased the ejection fraction (7.2% and 7.8% at 14 days and 7.2% and 8.0% at 28 days, resp.. After 28 days, there was a tendency for decreased infarct area and increased perfusion, compared to controls. No significant differences were observed between ASCs in saline or alginate hydrogel, in terms of retention and functional salvage. Conclusion. ASCs improved the myocardial function after AMI, but administration in the alginate hydrogel did not further improve retention of the cells or myocardial function.

The results of the paper suggest that both normal subjects and health pregnents tend to increasing in the content of urinary albumin with the increase of age and pregnant periods. The urinary albumin contents of patients with acute and chronic glomerulonep-hritis were compared with that of normal controls. There was highly significant difference (P < 0.001) in them. In patients with essential hypertention, diabetes mellitus and SLE etc., there was also significant raising in the urinary ALB, if the renal function of patients with these diseases were injured. It is a useful reference value for the estimation of renal function, judgement of patients condition and earlier index of the injury on glomerular function. It has an advantage in that it is reliable, safe and convenient

The goal of this trial is to compare two techniques for tensioning retropubic midurethral slings: a Mayo scissor between the tape and urethra vs. a Babcock clamp creating a measured loop underneath the urethra. The primary outcome is a composite of abnormal bladder function at 12 months post surgery. Abnormal bladder function is defined as bothersome stress incontinence or worsening over active bladder symptoms, a positive cough stress test, re-treatment of stress urinary incontinence, post-operative urinary retention requiring either catheterization beyond 6 weeks or surgical intervention. Secondary outcomes include the duration of post operative urinary retention, quality of life scores, and physical examination. This article describes the rationale and design of this clinical trial, which will be of interest to those who care for patient with pelvic floor disorders such as stress urinary incontinence.

Background: Renal cortical scintigraphic studies challenge the role of vesicoureteric reflux in renal scar development, emphasizing instead the part played by acute pyelonephritis. Objective: To determine the prevalence of renal cortical defects in a child cohort 2 years after the child's first diagnosed urinary tract infection and to analyze the relationship of these defects with acute illness variables, primary vesicoureteric reflux and recurrent infections. Materials and methods: In a prospective cohort study, 193 children younger than 5 years with their first proven urinary tract infection underwent renal sonography, voiding cystourethrogram, and renal cortical scintigraphy within 15 days of diagnosis. Two years later, 150 of the 193 children, or 77.7%, had a further renal cortical scintigram, including 75, or 86.2%, of the 87 children who had acute scintigraphic defects. The relationship of cortical defects to age, gender, pre-treatment symptom duration, hospitalization, presence and grade of vesicoureteric reflux, and recurrent urinary tract infections was evaluated. Results: Overall, 20 of the 150 (13.3%; 95% confidence interval (CI) 8.3, 19.8) children had persistent defects 2 years after infection. This included 20 of 75 (26.7%; 95% CI 17.1, 38.1) with initially abnormal scintigrams. No new defects were detected. Although acute defects were more common in the young, those with persistent defects were older (median ages 16.4 vs. 6.8 months, P=0.004) than those with transient abnormalities. After adjustment for age, persistent defects were no longer associated with gender and were not predicted by acute illness variables, primary vesicoureteric reflux or recurrent infections. (orig.)

Renal and urinary levels of endothelial protein C receptor correlate with acute renal allograft rejection.

Directory of Open Access Journals (Sweden)

Lionel Lattenist

Full Text Available The Endothelial Protein C Receptor (EPCR is expressed on leukocytes, on endothelium of large blood vessels and to a lesser extent on capillaries. Membrane bound EPCR plays an important role in the activation of protein C which has anticoagulant, anti-inflammatory and cytoprotective effects. After cleavage by a protease EPCR is also found as a soluble protein. Acute rejection of kidney allografts can be divided in T-cell-mediated rejection (TCMR and antibody-mediated (ABMR rejection. The latter is characterized by strong activation of coagulation. Currently no reliable non-invasive biomarkers are available to monitor rejection. Renal biopsies were available from 81 renal transplant patients (33 without rejection, 26 TCMR and 22 ABMR, we had access to mRNA material, matched plasma and urine samples for a portion of this cohort. Renal EPCR expression was assessed by RT-PCR and immunostaining. Plasma and urine sEPCR levels were measured by ELISA. ABMR patients showed higher levels of EPCR mRNA than TCMR patients. EPCR expression on glomeruli was significantly elevated in ABMR patients than in TCMR or control patients. In the peritubular capillaries EPCR expression was higher in ABMR patients than in control patients. EPCR expression was higher in tubules and arteries of rejection patients than in control patients. Plasma sEPCR levels did not differ. Urine sEPCR levels were more elevated in the ABMR group than in patients with TCMR or without rejection. ROC analysis demonstrated that urinary sEPCR is appropriate to discriminate between ABMR patients and TCMR or control patients. We conclude that urinary sEPCR could be a novel non-invasive biomarker of antibody mediated rejection in renal transplantation.

The effect of gamma-irradiation on plasma total protein nitrogen and urinary total nitrogen was studied in the desert rodent, psammomy obesus obesus and albino rats subjected to dietary protein deficiency. In albino rats kept on high protein diet, the radiation syndrome resulted in urine retention, while in those kept on non-protein diet, such phenomenon was recorded only with the high radiation level of 1170r. Radiation exposure to 780 and 1170r caused remarkable diuresis in psammomys obesus obesus whereas they induced significant urine retention in albino rats. The levels of plasma total protein nitrogen and urinary total nitrogen were higher in albino rats maintained on high protein diet than in those kept on non-protein diet. Radiation exposure caused an initial drop in plasma total protein nitrogen concentration, concomitant with an initial rise in total urinary nitrogen, radiation exposure of psammomys obesus obesus caused significant increase in the levels of plasma protein nitrogen and urinary total nitrogen. Psammomys obesus obesus seemed to be more affected by radiation exposure than did the albino rats

Stones in the urinary tract are a common condition but there is paucity of data on their population-based estimates in India. We describe our findings of the burden of urinary stones during a cross-sectional study with another primary goal. We conducted the study at Ballabgarh Health and Demographic Surveillance System, Haryana, among residents aged 18 years or above. We used simple random sampling to enrol participants. Self-reported history of urinary stones was elicited through an interview schedule. Results of the descriptive analysis were described as proportions with 95% confidence intervals (CI) or as mean wherever applicable. Bivariate analysis was done using t-test and chi-square test as applicable. The response rate for our study was 86.6%; lifetime prevalence (95% CI) of urinary stones was 7.9% (5.7, 10.8). In a majority of participants, urinary stones were diagnosed at an age of 20-40 years (55.9%), mostly by an ultrasonography examination (94.1%). A high burden of urinary stones is indicated in the working-age population in northern India at the community level. Untreated urinary stones can lead to an acute emergency (colic) or may have long-term adverse consequences, e.g. hydronephrosis, which have implications for the healthcare delivery system.

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

2012-02-01

A seventy two year old man presented to the Emergency Department with clinical features of colonic obstruction. Subsequent radiological investigations confirmed this impression and revealed the aetiology to be compression of the sigmoid colon against the sacrum by a massively distended urinary bladder. Chronic urinary retention due to benign prostatic hypertrophy is an extremely unusual cause of large bowel obstruction. Little in this patient\\'s clinical findings suggested this aetiology. We reviewed the literature in this area and highlight the benefits of CT scanning over contrast studies.

To determine the epidemiology of urological emergencies in a university hospital and the interest of a dedicated urological emergency unit. In 2008, a dedicated urological emergency unit was individualized in our department of urology. We conducted a retrospective study including all patients consulting in this unit in 2009 with epidemiological, clinical and therapeutic data. During 2009, 1257 patients consulted in this unit. Main diagnoses were acute urinary retention (303, 24.11%), renal colic (219, 17.42%), urinary infections (278, 22.11%), postoperative complications (141, 11.22%), symptomatic benign prostate hyperplasia (65, 5.17%), genitourinary cancers (61, 4.85%), trauma of urinary apparel (41, 3.26%), and spermatic cords torsion (10, 0.8%). In 99 cases (7.88%) diagnosis did not involved the urinary system. The treatment was surgical in 213 (17.7%) cases, technical procedure under local anesthesia in 368 (29.3%) and a medical treatment in 675 (53.7%) cases. Six hundred and sixty (52.5%) patients were managed ambulatory whereas 596 (47.5%) needed hospitalization. The opening of a dedicated urological emergency unit lead to 1257 emergency consultations. Frequent etiologies were acute urinary retention, renal colic and urinary infection. The creation of this unit allowed to register and to valorize this emergency activity through the ATU emergency amount. Copyright © 2013. Published by Elsevier Masson SAS.

THE ROLE OF CEPHALOSPORINS IN URINARY TRACT INFECTIONS TREATMENT IN CHILDREN

2012-01-01

Full Text Available The problem of effective diagnosis and treatment of acute urinary tract infection (UTI remains relevant in connection with a high prevalence of this nosology and the growth of antibiotic resistance. The need to use of antibiotics in the treatment of acute UTI in children has no doubt. At the same time there are different opinions on duration, and route of administration of the antibiotics. It is not always possible to achieve the desirable effect after a long courses of antibiotic therapy, and duration of fever as a clinical marker of inflammation, was not significantly different in the appointment of oral and parenteral antibiotics. The effectiveness of treatment of acute urinary tract infections in young children depends not on the way of administration but on the dose that ensures the achievement of the minimum inhibitory concentration of the drug. Drugs of choice in patients with acute UTI are: inhibitor-protected aminopenicillins and cephalosporins of II and III generation. However, in children with acute UTI who received antibiotic therapy previously, as well as in suspected obstructive uropathy, the most likely causative agent is toxin-producing E. coli, which has a high degree of resistance to aminopenicillins, including protected. Therefore, the drugs of choice in this category of children should be the antibiotics of the cephalosporin group II–III generation.

Full Text Available Background: The aim of this study was to assess the efficacy and safety of a new minimally-invasive surgical procedure using trans-obturator Tape (TOT to treat female stress urinary incontinence.Methods: This clinical trial study was performed from 2003 to 2004 in the Gynecology Department of Imam Hospital, Vali-e-Asr, Tehran, Iran. A total of 35 women with stress urinary incontinence underwent the TOT procedure. All patients underwent pre-operative clinical examination, cough-stress test (full bladder, uroflowmetry and post-voiding residual volume assessment. Results: The mean age of patients was 50 years, ranging from 26 to 74 years, with an average urinary stress incontinence duration of six years. The mean time of follow-up was 14 months (at 1, 6, 12 and 24 months and the average duration of surgery was about 20 minutes. The perioperative complication rate was 9% with no vascular, nerve or bowel injuries. The rate of hemorrhagic side effects (spontaneously-absorbed hematoma and blood loss not requiring blood transfusion was 2.9%. Post-operative urinary retention and vaginal erosion occurred in one case each; the former was treated by intermittent self-catheterization. In total, 91.4% of patients were completely cured and 8.6% were improved without failure of treatment. Conclusions: The present study confirms the results obtained by Delorme and coworkers, and allows us to consider TOT as a safe, minimally invasive and efficient short-term surgical technique for the treatment of female stress urinary incontinence, alone or in combination with prolapse repair. Following this study, a randomized control trial is recommended to compare TOT with the gold standard surgery for women with urinary incontinence.

Background: Non-contrast thin-section helical CT has gained acceptance for the diagnosis of urinary tract calculi in adults, but experience with the technique in children is limited. Purpose: To evaluate the utility of non-contrast thin section helical CT for the diagnosis of urinary tract calculi in children. Materials and methods: Radiology databases at three pediatric institutions were searched to identify all pediatric patients evaluated by ''renal stone'' protocol CT scans (no oral or intravenous contrast, scans covering the entire urinary tract obtained in helical mode with narrow collimation (< 5 mm)). CT scans were reviewed for the primary finding of urinary tract calculi, for secondary signs of acute urinary tract obstruction and for evidence of alternative diagnoses. Medical records were reviewed to determine clinical presentation and to confirm the eventual diagnosis. Results: One hundred thirty-seven scans of 113 children (mean age: 11.2 years) were studied. Thirty-eight of 94 examinations (40%) performed on 82 children for acute pain and/or hematuria showed ureteral calculi. Alternative diagnoses were suggested by CT on 16 scans (17%). Twenty-eight scans were performed on 10 asymptomatic children with known calculus disease confirming renal stone burden on 21 scans (75%) and persistent ureteral calculi on 6 scans (21%). Upper tract calculi were demonstrated on 10 of 15 scans (67%) performed to evaluate for calculi in patients with known non-calculus genitourinary tract abnormalities. Conclusions: Non-contrast thin section helical CT is a useful method to diagnose urinary tract calculi in children. Radiation dose in this retrospective study may exceed the lowest possible radiation dose for diagnostic accuracy. Further research is needed to optimize CT imaging parameters, while maintaining diagnostic accuracy and minimizing radiation dose. (orig.)

Full Text Available Most men will develop histological BPH if they live long enough. Approximately, half will develop benign prostatic enlargement (BPE and about half of these will get BOO with high bladder pressures and low flow, this in turn leads to detrusor wall hypertrophy. Many of these men will only have lower urinary tract symptoms (LUTS but a significant number will also suffer the other complications of BPH. These include urinary retention (acute and chronic, haematuria, urinary tract infection, bladder stones, bladder wall damage, renal dysfunction, incontinence and erectile dysfunction. Recognition of the complications of BPH/BOO early allows more effective management of these complications. This is particularly important for the more serious urinary infections and also for high-pressure chronic retention (HPCR. Complications of LUTS/BPH are very rare in clinical trials because of their strict inclusion and exclusion criteria but are more common in real life practice.

Full Text Available Abstract Complicated urinary tract infections (C-UTIs are those associated with structural or functional genitourinary abnormalities or with conditions that impair the host defence mechanisms, leading to an increased risk of acquiring infection or failing therapy. C-UTIs occur in patients with risk factors such as neurogenic dysfunction, bladder outlet obstruction, obstructive uropathy, bladder catheterisation, urologic instrumentation or indwelling stent, urinary tract post-surgical modifications, chemotherapy- or radiation-induced damage, renal impairment, diabetes and immunodeficiency. Multidetector CT and MRI allow comprehensive investigation of C-UTIs and systemic infection from an unknown source. Based upon personal experience at a tertiary care hospital focused on the treatment of infectious illnesses, this pictorial essay reviews with examples the clinical features and cross-sectional imaging findings of C-UTIs affecting the lower urinary tract and male genital organs. The disorders presented include acute infectious cystitis, bladder mural abscesses, infections of the prostate and seminal vesicles, acute urethritis and related perineal abscesses, funiculitis, epididymo-orchitis and scrotal abscesses. Emphasis is placed on the possible differential diagnoses of lower C-UTIs. The aim is to provide radiologists greater familiarity with these potentially severe disorders which frequently require intensive in-hospital antibiotic therapy, percutaneous drainage or surgery. Teaching Points • Complicated urinary tract infections occur in patients with structural or functional risk factors. • CT and MRI comprehensively investigate complicated urinary infections and sepsis from unknown sources. • Infections of the urinary bladder, prostate, seminal vesicles, urethra and scrotum are presented. • Emphasis is placed on differential diagnoses of complicated lower urogenital infections. • Unsuspected urinary infections may be detected on CT

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

Debridement, antibiotics, and implant retention (DAIR) is a widely used treatment modality for early acute prosthetic joint infection (PJI). A preoperative risk score was previously designed for predicting DAIR failure, consisting of chronic renal failure (K), liver cirrhosis (L), index surgery (I), cemented prosthesis (C), and C-reactive protein >115 mg/L (KLIC). The aim of this study was to validate the KLIC score in an external cohort. We retrospectively evaluated patients with early acute PJI treated with DAIR between 2006 and 2016 in 3 Dutch hospitals. Early acute PJI was defined as infection-related death within 60 days after debridement. A total of 386 patients were included. Failure occurred in 148 patients (38.3%). Patients with KLIC scores of ≤2, 2.5-3.5, 4-5, 5.5-6.5, and ≥7 had failure rates of 27.9%, 37.1%, 49.3%, 54.5%, and 85.7%, respectively (P < .001). The receiver-operating characteristic curve showed an area under the curve of 0.64 (95% confidence interval 0.59-0.69). A KLIC score higher than 6 points showed a specificity of 97.9%. The KLIC score is a relatively good preoperative risk score for DAIR failure in patients with early acute PJI and appears to be most useful in clinical practice for patients with low or high KLIC scores.

2007-04-01

Full Text Available OBJECTIVE: The present work describes our experience in surgical correction of stress urinary incontinence, comparing both the TVT and the TVT-O techniques. METHOD: Between October 2001 and March 2004, 76 patients underwent the TVT procedure. Between January 2004 and January 2005, 98 surgical corrections of urinary incontinence were carried out using the TVT-O technique. RESULTS: Median operative time was 28 minutes for TVT and 7 minutes for TVT-O. Intraoperative complications for TVT occurred in 4 patients (6.6%: urinary bladder perforation in 3 patients (5%, p = 0.0228 and parietal peritoneum perforation in 1 case (1.6%. No intraoperative complications took place during TVT-O. Immediate postoperative complications: transient urinary retention in TVT, 2 cases (2.6% and overcorrection in TVT-O (1% which was readjusted within 24 hours. There were no late complications after TVT. There were 2 cases (2.04% with late complications in TVT-O. TVT and TVT-O resulted in correction of incontinence in 100% of the patients. CONCLUSION: TVT and TVT-O are two effective techniques for the correction of stress urinary incontinence. TVT-O would seem to be a technique much easier to perform resulting in less intraoperative complications.

Full Text Available Background/Aims. Acute kidney injury is a common problem for patients with cirrhosis and is associated with poor survival. We aimed to examine the association between type of acute kidney injury and 90-day mortality. Methods. Prospective cohort study at a major US liver transplant center. A nephrologist’s review of the urinary sediment was used in conjunction with the 2007 Ascites Club Criteria to stratify acute kidney injury into four groups: prerenal azotemia, hepatorenal syndrome, acute tubular necrosis, or other. Results. 120 participants with cirrhosis and acute kidney injury were analyzed. Ninety-day mortality was 14/40 (35% with prerenal azotemia, 20/35 (57% with hepatorenal syndrome, 21/36 (58% with acute tubular necrosis, and 1/9 (11% with other (p=0.04 overall. Mortality was the same in hepatorenal syndrome compared to acute tubular necrosis (p=0.99. Mortality was lower in prerenal azotemia compared to hepatorenal syndrome (p=0.05 and acute tubular necrosis (p=0.04. Ten participants (22% were reclassified from hepatorenal syndrome to acute tubular necrosis because of granular casts on urinary sediment. Conclusions. Hepatorenal syndrome and acute tubular necrosis result in similar 90-day mortality. Review of urinary sediment may add important diagnostic information to this population. Multicenter studies are needed to validate these findings and better guide management.

To test the role of hospital-acquired symptomatic urinary tract infection (SUTI) as an independent predictor of discharge disposition in the acute stroke patient. A retrospective study of data collected from a stroke registry service. The registry is maintained by the Specialized Programs of Translational Research in Acute Stroke Data Core. The Specialized Programs of Translational Research in Acute Stroke is a national network of 8 centers that perform early phase clinical projects, share data, and promote new approaches to therapy for acute stroke. A single university-based hospital. We performed a data query of the fields of interest from our university-based stroke registry, a collection of 200 variables collected prospectively for each patient admitted to the stroke service between July 2004 and October 2009, with discharge disposition of home, inpatient rehabilitation, skilled nursing facility, or long-term acute care. Baseline demographics, including age, gender, ethnicity, and National Institutes of Health Stroke Scale (NIHSS) score, were collected. Cerebrovascular disease risk factors were used for independent risk assessment. Interaction terms were created between SUTI and known covariates, such as age, NIHSS, serum creatinine level, history of stroke, and urinary incontinence. Because patients who share discharge disposition tend to have similar length of hospitalization, we analyzed the effect of SUTI on the median length of stay for a correlation. Days in the intensive care unit and death were used to evaluate morbidity and mortality. By using multivariate logistic regression, the data were analyzed for differences in poststroke disposition among patients with SUTI. Of 4971 patients admitted to the University of Texas at Houston Stroke Service, 2089 were discharged to home, 1029 to inpatient rehabilitation, 659 to a skilled nursing facility, and 226 to a long-term acute care facility. Patients with an SUTI were 57% less likely to be discharged home

2016-01-01

One of the key mechanisms involved in renal Na(+) retention in chronic heart failure (CHF) is activation of epithelial Na(+) channels (ENaC) in collecting tubules. Proteolytic cleavage has an important role in activating ENaC. We hypothesized that enhanced levels of proteases in renal tubular fluid activate ENaC, resulting in renal Na(+) retention in rats with CHF. CHF was produced by left coronary artery ligation in rats. By immunoblotting, we found that several urinary serine proteases were significantly increased in CHF rats compared with sham rats (fold increases: furin 6.7, prostasin 23.6, plasminogen 2.06, and plasmin 3.57 versus sham). Similar increases were observed in urinary samples from patients with CHF. Whole-cell patch clamp was conducted in cultured renal collecting duct M-1 cells to record Na(+) currents. Protease-rich urine (from rats and patients with CHF) significantly increased the Na(+) inward current in M-1 cells. Two weeks of protease inhibitor treatment significantly abrogated the enhanced diuretic and natriuretic responses to ENaC inhibitor benzamil in rats with CHF. Increased podocyte lesions were observed in the kidneys of rats with CHF by transmission electron microscopy. Consistent with these results, podocyte damage markers desmin and podocin expressions were also increased in rats with CHF (increased ≈2-folds). These findings suggest that podocyte damage may lead to increased proteases in the tubular fluid, which in turn contributes to the enhanced renal ENaC activity, providing a novel mechanistic insight for Na(+) retention commonly observed in CHF. © 2015 American Heart Association, Inc.

One of the key mechanisms involved in renal Na+ retention in chronic heart failure (CHF) is activation of epithelial Na+ channels (ENaC) in collecting tubules. Proteolytic cleavage has an important role in activating ENaC. We hypothesized that enhanced levels of proteases in renal tubular fluid activate ENaC resulting in renal Na+ retention in rats with CHF. CHF was produced by left coronary artery ligation in rats. By immunoblotting, we found that several urinary serine proteases were significantly increased in CHF rats compared to sham rats (fold increases: furin 6.7, prostasin 23.6, plasminogen 2.06 and plasmin 3.57 vs. sham). Similar increases were observed in urinary samples from patients with CHF. Whole-cell patch-clamp was conducted in cultured renal collecting duct M-1 cells to record Na+ currents. Protease-rich urine (from rats and patients with CHF) significantly increased the Na+ inward current in M-1 cells. Two weeks of protease inhibitor treatment significantly abrogated the enhanced diuretic and natriuretic responses to ENaC inhibitor benzamil in rats with CHF. Increased podocyte lesions were observed in the kidneys of rats with CHF by transmission electron microscopy. Consistent with these results, podocyte damage markers desmin and podocin expressions were also increased in rats with CHF (increased ~2 folds). These findings suggest that podocyte damage may lead to increased proteases in the tubular fluid which in turn contributes to the enhanced renal ENaC activity, providing a novel mechanistic insight for Na+ retention commonly observed in CHF.

Metabolomic profiling combines Nuclear Magnetic Resonance spectroscopy with supervised statistical analysis that might allow to better understanding the mechanisms of a disease. In this study, the urinary metabolic profiling of individuals with porphyrias was performed to predict different types of disease, and to propose new pathophysiological hypotheses. Urine 1 H-NMR spectra of 73 patients with asymptomatic acute intermittent porphyria (aAIP) and familial or sporadic porphyria cutanea tarda (f/sPCT) were compared using a supervised rule-mining algorithm. NMR spectrum buckets bins, corresponding to rules, were extracted and a logistic regression was trained. Our rule-mining algorithm generated results were consistent with those obtained using partial least square discriminant analysis (PLS-DA) and the predictive performance of the model was significant. Buckets that were identified by the algorithm corresponded to metabolites involved in glycolysis and energy-conversion pathways, notably acetate, citrate, and pyruvate, which were found in higher concentrations in the urines of aAIP compared with PCT patients. Metabolic profiling did not discriminate sPCT from fPCT patients. These results suggest that metabolic reprogramming occurs in aAIP individuals, even in the absence of overt symptoms, and supports the relationship that occur between heme synthesis and mitochondrial energetic metabolism.

Background Urinary tract infection (UTI) is an infection that affects part of the urinary tract. Ultrasound is a noninvasive test that can demonstrate the size and shape of kidneys, presence of dilatation of the ureters, and the existence of anatomic abnormalities. The aim of the study is to estimate the value of ultrasound in detecting urinary tract anomalies after first attack of UTI. Methods This study was conducted at the Nephrology Clinic, New Children's Hospital, Faculty of Medicine, Cairo University, from August 2012 to March 2013, and included 30 children who presented with first attack of acute febrile UTI. All patients were subjected to urine analysis, urine culture and sensitivity, serum creatinine, complete blood count, and imaging in the form of renal ultrasound, voiding cysto-urethrography, and renal scan. Results All the patients had fever with a mean of 38.96°C ± 0.44°C and the mean duration of illness was 6.23 ± 5.64 days. Nineteen patients (63.3%) had an ultrasound abnormality. The commonest abnormalities were kidney stones (15.8%). Only 2 patients who had abnormal ultrasound had also vesicoureteric reflux on cystourethrography. Sensitivity of ultrasound was 66.7%, specificity was 37.5%, positive predictive value was 21.1%, negative predictive value was 81.8%, and total accuracy was 43.33%. Conclusion We concluded that ultrasound alone was not of much value in diagnosing and putting a plan of first attack of febrile UTI. It is recommended that combined investigations are the best way to confirm diagnosis of urinary tract anomalies. © The Author(s) 2015.

Full Text Available Abstract Introduction We present a case of nonseminomatous germ cell tumor of the testes with acute urinary retention secondary to urethral metastasis. This presentation, and similar cases of urethral metastasis from this tumor, have not been reported previously. Case presentation A 35-year-old Caucasian man presented to hospital with a history of acute urinary retention. On examination he was found to have right testicular enlargement with raised β-human chorionic gonadotrophin, serum α-fetoprotein and lactate dehydrogenase levels. He underwent radical left inguinal orchidectomy and histology confirmed a nonseminomatous germ cell tumor of the testes. Cystoscopy carried out due to urinary retention showed penile metastasis and the biopsy confirmed metastatic malignant undifferentiated teratoma. Staging computed tomography scan and magnetic resonance imaging of the pelvis showed pulmonary, pelvic nodal, ischial and penile metastasis. The diagnosis of the International Germ Cell Cancer Collaborative Group of poor prognosis metastatic nonseminomatous germ cell tumor was made, following which he received four cycles of bleomycin, etoposide and cisplatin chemotherapy with curative intent. He had a complete marker and an excellent radiological response. He is currently under follow up. Conclusion The unusual presentation of lymphovascular spread in this case of nonseminomatous germ cell tumor highlights the need to include routine pelvic imaging in the assessment and follow up of testicular cancer.

Recurrent uncomplicated urinary tract infections in women: a review.

Nosseir, Sandy B; Lind, Lawrence R; Winkler, Harvey A

2012-03-01

Recurrent urinary tract infections most often present with symptoms of irritative voiding. In most cases, they are caused by reinfection with a previously isolated organism. Patients with one or more symptoms of uncomplicated recurrent urinary tract infection should undergo thorough examination and screening for underlying comorbidities that increase susceptibility. When frequent reinfections, empiric treatment relapse, persistent infections, or risk factors for complicated infections are encountered, patients may benefit from urodynamics, cystoscopy, renal ultrasound, intravenous urogram, or voiding cystourethrogram to evaluate for anatomic, functional, or metabolic abnormalities affecting the urinary tract (e.g., stones, stricture, obstruction, vesicoureteral reflux, lesions, detrusor underactivity). These patients may benefit from culture-guided empiric treatment and further evaluation by urology, nephrology, or infectious disease specialists. In patients with a history of uncomplicated urinary tract infections, empiric treatment guided by local antimicrobial resistance may efficiently treat a suspected recurrence. After successful treatment of the acute infection, postcoital prophylaxis, continuous prophylaxis, or self-start empiric treatment may be selected based on frequency of recurrent infections, temporal relation to intercourse, and patient characteristics. Ancillary measures such as probiotics, cranberry products, or local estrogen replacement may also be considered. This article will review the current definition, epidemiology, pathogenesis, diagnosis, work-up, treatment, treatment side effects, and prevention of recurrent urinary tract infections in women. A suggested algorithm for evaluation and treatment based on current literature is provided.

Purpose. A clinical feasibility study using a removable prostate stent as fiducial for image-guided radiotherapy (IGRT) of localized prostate cancer (PC). Material and methods. The study included patients with local or locally advanced PC. The clinical target volume (CTV) was outlined on magnetic resonance (MR) images co-registered to planning computer tomography (CT) images. Daily online IGRT was delivered using the stent as fiducial. Risk of migration was estimated using multiple MR. Acute urinary toxicity was scored using the international prostate symptom score (IPSS). Late gastro-intestinal (GI) and genito-urinary (GU) toxicity was scored using the Radio Therapy Oncology Group (RTOG) score, biochemical failure (BF) was defined as an elevation of prostate specific antigen (PSA) above nadir plus 2 ng/ml after radiotherapy. Results. One hundred men were enrolled in the study. Ninety completed radiotherapy with the stent as fiducial. No migration of the stent was seen, but three cases of dislocation of the stent to the bladder were observed. Acute urinary toxicity based on IPSS was comparable to toxicity in patients who had gold markers (GM) as fiducials. Removal of the stent was associated with a high frequency of urinary retention. Late GI and GU toxicity and BF were comparable to those of other studies, but longer observation time is needed. Conclusions. This study reports the first clinical results of using a prostate stent as fiducial. No migration of the stent observed. Dislocation of the stent to the urinary bladder was observed in three cases, requiring removal of the stent and insertion of a new fiducial. Acute toxicity during radiotherapy evaluated from IPSS was comparable to toxicity in patients with GM. Removal of the stent was associated with a high frequency of post procedural urinary retention. Late toxicity and BF were comparable to those of other studies, though longer observation time is needed

To compare symptoms with urinary metabolite levels, 900 workers from 7 organic solvent-using industries were studied. Urinary metabolites were determined using a high performance liquid chromatograph. Urinary hippuric acid concentrations exceeding the reference value (2.5 g/g creatinine) were found in 78 (8.7%) workers. However, only 3 (0.3%) and 1 (0.1%) of the participants exceeded the reference value for mandelic (0.8 g/g creatinine) and total methylhippuric acid (1.5 g/g creatinine), respectively. The sum of the values of the ratio of measured urinary metabolite concentration to the corresponding ACGIH's biological exposure indices (BEI) [(HA/BEI of HA + MHA/BEI of MHA + MA/BEI of MA)] exceeded 1.0 in 166 (18.4%) workers. Majority of them were from the footwear manufacturing industry (63/129 or 49.2%). Questionnaire interviews were also administered to determine the prevalence of symptoms while at work (acute symptoms) or within the past 6 months (chronic symptoms). Urinary metabolite levels of individual and mixed solvents were compared with the symptoms of all workers. Analysis using Spearman's rank correlation showed in workers whose urinary hippuric acid exceeded 3.75 g/g creatine (1.5 x BEI), significant correlation between their hippuric acid levels and subjective complaints. Workers whose sum of the values of the ratio of measured urinary metabolite concentration to corresponding BEI exceeded 1.5 were selected and comparing this level with their symptoms, significant correlation was also noted in some complaints.

Enterovesical fistula are pathological connections between the bladder and pelvic intestinal segments. It consists of a rare complication of neoplastic and inflammatory pelvic disorders, in addition to iatrogenic or traumatic injuries, and correlates with both high morbidity and mortality indexes. Male patient, 61 years old, admitted at the hospital clinics featuring abdominal pain and distension, vomiting and fecal retention. Patient's pathological precedents include high blood pressure, diabetes mellitus, vesical dysfunction and recurrent urinary tract infection on the past three years. Magnetic resonance imaging of abdomen and pelvis revealed enterovesical fistula in association with colon diverticular disease of the sigmoid. Management of choice consisted of partial colectomy with bowel lowering and partial cystectomy with surgical double-J stent insertion. Although consisting of a gastrointestinal primary affection, patients with enterovesical fistula usually search for medical help charging urinary tract features. In this particular case, our patient was admitted with gastrointestinal symptoms, reasoned by diagnostic delay, as the patient had already attended at multiple centers with urinary symptoms. Despite being an unusual affection, recurrent urinary tract infection associated with colon diverticular disease must always be considered at differential diagnosis of recurrent urinary tract infection as it concurs with high morbidity and mortality.

Objectives This study aimed to determine the diagnostic and prognostic value of urinary biomarkers of intrinsic acute kidney injury (AKI) when patients were triaged in the emergency department. Background Intrinsic AKI is associated with nephron injury and results in poor clinical outcomes. Several urinary biomarkers have been proposed to detect and measure intrinsic AKI. Methods In a multicenter prospective cohort study, 5 urinary biomarkers (urinary neutrophil gelatinase–associated lipocalin, kidney injury molecule-1, urinary liver-type fatty acid binding protein, urinary interleukin-18, and cystatin C) were measured in 1,635 unselected emergency department patients at the time of hospital admission. We determined whether the biomarkers diagnosed intrinsic AKI and predicted adverse outcomes during hospitalization. Results All biomarkers were elevated in intrinsic AKI, but urinary neutrophil gelatinase-associated lipocalin was most useful (81% specificity, 68% sensitivity at a 104-ng/ml cutoff) and predictive of the severity and duration of AKI. Intrinsic AKI was strongly associated with adverse in-hospital outcomes. Urinary neutrophil gelatinase-associated lipocalin and urinary kidney injury molecule 1 predicted a composite outcome of dialysis initiation or death during hospitalization, and both improved the net risk classification compared with conventional assessments. These biomarkers also identified a substantial subpopulation with low serum creatinine at hospital admission, but who were at risk of adverse events. Conclusion Urinary biomarkers of nephron damage enable prospective diagnostic and prognostic stratification in the emergency department. PMID:22240130

Hemangioma of the prostate - an unusual cause of lower urinary tract symptoms: Case report

Directory of Open Access Journals (Sweden)

2011-04-01

Full Text Available Abstract Background Hemangioma of the prostate gland is extremely rare and only a few cases have been reported. There have been several cases of hemangioma of posterior urethra, urinary bladder and periprostatic plexus in the literature, all presenting with hematuria or hematospermia. Diagnosis of prostatic hemangioma is difficult due to its rarity and unspecific symptoms such as hematuria, hematospermia or lower urinary tract symptoms. It cannot be detected by conventional examinations such as cystoscopy or standard rectal ultrasonography. Case presentation We present a case of prostatic hemangioma in an 84-year old male presenting with lower urinary tract symptoms. Bleeding has not been a feature in our case and diagnosis was not made until after operation. The patient was treated as a case of bladder neck outflow obstruction with transurethral resection of prostate gland and simultaneous bladder neck incisions. A period of self-catheterization was instituted due to postoperative urinary retention as the result of detrusor insufficiency. Conclusion Hemangioma of prostate gland is extremely rare and symptomatic prostatic hemangioma should be treated either by transurethral resection of prostate or laser evaporation.

Evaluation of DNA damage in patients with arsenic poisoning: urinary 8-hydroxydeoxyguanine

The relationship between arsenic exposure and DNA damage in patients with acute or chronic arsenic poisoning was analyzed. Urinary 8-hydroxydeoxyguanine (8-OHdG) concentrations were measured as an indication of oxidative DNA damage. A remarkable increase in 8-OHdG in the urine was observed in 60% of 52 patients with acute arsenic poisoning from the accidental oral intake of the arsenic trioxide. This was two- to threefold higher than levels in normal healthy subjects (n = 248). There was a clear relationship between arsenic concentrations in urine after acute poisoning and elevated levels of 8-OHdG. Levels of urinary 8-OHdG returned to normal within 180 days after the acute arsenic poisoning event. In patients chronically poisoned by the consumption of well water with elevated levels of arsenate [As(V)], elevated 8-OHdG concentrations in urine were also observed. A significant correlation between the 8-OHdG levels and arsenic levels in the urine was observed in 82 patients with chronic poisoning. Thus, evidence of oxidative DNA damage occurred in acute arsenic poisoning by arsenite [As(III)] and in chronic arsenic poisoning by As(V). In chronic poisoning patients provided low-arsenic drinking water, evidence of DNA damage subsided between 9 months and 1 year after the high levels of arsenic intake were reduced. The initial level of arsenic exposure appeared to dictate the length of this recovery period. These data indicate that some aspects of chronic and acute arsenic poisoning may be reversible with the cessation of exposure. This knowledge may contribute to our understanding of the risk elevation from arsenic carcinogenesis and perhaps be used in a prospective fashion to assess individual risk

We examined the diagnostic accuracy of routine imaging studies (ultrasonography and micturating cystography) for predicting long-term parenchymal renal damage after a first febrile urinary tract infection. This study addressed the secondary objective of a prospective trial evaluating different antibiotic regimens for the treatment of acute pyelonephritis. Data for 300 children urinary tracts were mostly normal. The acute technetium-99m-dimercaptosuccinic acid scans showed pyelonephritis in 54% of cases. Renal scarring developed in 15% of cases. The ultrasonographic and cystographic findings were poor predictors of long-term damage, showing minor sonographic abnormalities for 12 and reflux for 23 of the 45 children who subsequently developed scarring. The benefit of performing ultrasonography and scintigraphy in the acute phase or cystourethrography is minimal. Our findings support (1) technetium-99m-dimercaptosuccinic acid scintigraphy 6 months after infection to detect scarring that may be related to long-term hypertension, proteinuria, and renal function impairment (although the degree of scarring was generally minor and did not impair renal function) and (2) continued surveillance to identify recurrent urinary tract infections that may warrant further investigation.

Objective: Clinical characteristic, diagnosis and treatment of radiation urinary bladder disease induced by radiation therapy for cancers in the pelvis were inquired into for providing diagnostic basis. Methods: Statistical analysis for the clinical cases was carried out. Results: The incidence of radiation bladder diseases induced by radiation therapy of cervix cancer are about 0.8%-2.96%, with an average of 2.14%. Radiation bladder disease is divided into acute radiation cystitis, chronic radiation cystitis and radiation vesical fistula. Chronic radiation cystitis is seen most often in the clinic and its main clinical symptom is painless macroscopic hematuria, which is again subdivided into slight and severe degrees. Diagnosis should include history of exposure to radiation, which dose exceed the dose threshold, and typical clinical characteristics. Conclusion: The characteristics, types and diagnostic basis of radiation urinary bladder disease analyzed in this study can provide the reference for drawing up diagnostic standard

The aim of this article was to assess the usefulness of procalcitonin (PCT) as a marker for predicting dilating (grades III-V) vesicoureteral reflux (VUR) in young children with a first febrile urinary tract infection. Children ≤2 years of age with a first febrile urinary tract infection were prospectively evaluated. Serum samples were tested for PCT at the time of admission to a tertiary hospital. All children underwent renal ultrasonography (US), Tc-dimercaptosuccinic acid renal scan, and voiding cystourethrography. The diagnostic characteristics of PCT test for acute pyelonephritis and dilating VUR were calculated. Of 272 children analyzed (168 boys and 104 girls; median age, 5 months), 169 (62.1%) had acute pyelonephritis. There was VUR demonstrated in 97 (35.7%), including 70 (25.7%) with dilating VUR. The median PCT value was significantly higher in children with VUR than in those without (P predictors of dilating VUR. PCT is useful for diagnosing acute pyelonephritis and predicting dilating VUR in young children with a first febrile urinary tract infection. A voiding cystourethrography is indicated only in children with high PCT values (≥1.0 ng/mL) and/or abnormalities found on a US.

The clinical syndromes comprising urinary tract infection (UTI) continue to exert significant impact on millions of patients worldwide, most of whom are otherwise healthy women. Antibiotic therapy for acute cystitis does not prevent recurrences, which plague up to one fourth of women after an initial UTI. Rising antimicrobial resistance among uropathogenic bacteria further complicates therapeutic decisions, necessitating new approaches based on fundamental biological investigation. In this review, we highlight contemporary advances in the field of UTI pathogenesis and how these might inform both our clinical perspective and future scientific priorities. PMID:27692880

Various strategies have been applied to increase the engraftment of an intramyocardial cell transplant (Tx) to treat ischemic myocardium. Thereby, co-transplanted fibroblasts (FB) improve the long-term survival of stem cell derivatives (SCD) in a murine model of myocardial infarction. For therapeutic use, the time frame in which FB exert putative supportive effects needs to be identified. Therefore, we tracked the biodistribution and retention of SCD and FB in vivo using highly sensitive positron emission tomography (PET) imaging. Murine [ 18 F]-fluorodeoxyglucose (FDG) labeled SCD and FB were transplanted after left anterior descending artery (LAD) ligation into the border zone of the ischemic area in female C57BL/6 mice. Cardiac retention and biodistribution during the initial 2 h after injection were measured via PET imaging. Massive initial cell loss occurred independently of the cell type. Thereby, FB were retained slightly, yet significantly better than SCD until 60 min post-injection (7.5 ± 1.7 vs. 5.2 ± 0.7 % ID at 25 min and 7.0 ± 1.5 vs. 4.8 ± 0.8 % ID at 60 min). Thereafter, a fraction of ∝5 % that withstood the massive initial washout remained at the site of injection independently of the applied cell type (120 min, SCD vs. FB P = 0.64). Most of the lost cells were detected in the lungs (∝30 % ID). We were able to quantitatively define the retention and biodistribution of different cell types via PET imaging in a mouse model after intramyocardial Tx. The utmost accuracy was achieved through this cell- and organ-specific approach by correcting PET data for cellular FDG efflux. Thereby, we observed a massive initial cell loss of ∝95 %, causing low rates of long-term engraftment for both SCD and FB. We conclude that FB are not privileged compared to SCD regarding their acute retention kinetics, and therefore exert their beneficial effects at a later time point. (orig.)

Various strategies have been applied to increase the engraftment of an intramyocardial cell transplant (Tx) to treat ischemic myocardium. Thereby, co-transplanted fibroblasts (FB) improve the long-term survival of stem cell derivatives (SCD) in a murine model of myocardial infarction.

The prevalence of urinary tract infection in children with severe acute malnutrition: a narrative review

Science.gov (United States)

Uwaezuoke, Samuel N

2016-01-01

This article aims to review the current evidence which shows that the prevalence of urinary tract infection (UTI) has been increasing in children with severe acute malnutrition (SAM). UTI remains one of the most common causes of febrile illness in pediatric practice. Most studies conducted among hospitalized children with complicated SAM have reported high prevalence rates of UTI. Clearly, the knowledge of baseline risk of UTI can help clinicians to make informed diagnostic and therapeutic decisions in these children. From the global reports reviewed in this article, UTI prevalence rates range from as low as 6% to as high as 37% in developing countries, while the most common bacterial isolates from urine cultures are Gram-negative coliform organisms such as Escherichia coli and Klebsiella species. These findings form the basis for the current diagnostic and therapeutic guidelines for clinicians managing children with complicated SAM. With the reported high prevalence of UTI among these children and concerns over antibiotic resistance, more extensive data are required using standardized microbiological methods. Thus, the assessment of the performance of urine dipsticks and microscopy against the gold standard urine culture is an important step toward strengthening the evidence for the therapeutic guidelines for UTI in children with SAM.

Full Text Available We aimed to determine the effects of oxidative stress in urinary tract infection (UTI. One hundred sixty-four urine samples obtained from patients with the prediagnosis of acute UTI admitted to the Faculty of Medicine, Kahramanmaras Sutcu Imam University, were included in this study. Urine cultures were performed according to standard techniques. Urinary isolates were identified by using API ID 32E. The catalase and superoxide dismutase activity and the lipid peroxidation levels known as oxidative stress markers were measured in all urine samples. Thirty-six pathogen microorganisms were identified in positive urine cultures. These microorganisms were as follows: 23 (63.8% E coli, 5 (13.8% P mirabilis, 4 (11.1% K pneumoniae, 2 (5.5% Candida spp, 1 (2.7% S saprophyticus, and 1 (2.7% P aeruginosa. It was observed that lipid peroxidation levels were increased while catalase and superoxide dismutase activities were decreased in positive urine cultures, compared to negative cultures. We conclude that urinary tract infection causes oxidative stress, increases lipid peroxidation level, and leads to insufficiency of antioxidant enzymes.

Detrusor smooth muscle (DSM) underactivity may lead to urinary retention (UR). Electroacupuncture (EA) at BL33 may be effective in improving DSM contractions. This study aimed to investigate: (1) the effect of EA at BL33; and (2) the effect of different manipulation methods at BL33 on the modulation of DSM contractions in UR rats. 30 male Sprague-Dawley rats were anaesthetised with urethane and modelled by urethral outlet obstruction. First, 2 Hz EA at BL33, SP6 and LI4 wasrandomly applied to the UR rats for 5 min to observe the immediate effects (n=10); second, manual acupuncture (MA) (n=10) and 100 Hz EA (n=10) were applied with the same programme. DSM electromyography (EMG) and cystometrogram data were evaluated. (1) 2 Hz EA at BL33 and SP6 significantly increased DSM discharging frequency (0.80±0.10 Hz, P0.05). Compared with SP6, EA at BL33 had greater positive effects on DSM discharging frequency, duration of discharging, and duration of voiding (all P<0.05). (2) No statistically significant differences were shown between MA, 2 Hz EA and 100 Hz EA interventions when stimulating at BL33, SP6 or LI4. EA at BL33 improved DSM contractions to a greater degree than EA at SP6 or LI4. There were no differences in effect when stimulating using 2 Hz EA, 100 Hz EA and MA. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

: The aim of this study was to examine the factors affecting the retention of registered nurses (RNs) and validate the revised Casey-Fink Nurse Retention Survey (2009). : Creating an organizational culture of retention may reduce nurse turnover. Focusing on why nurses leave and identifying factors why nurses stay are essential. : A descriptive survey design gathered data from RNs with 1 or more years of experience providing direct patient care and employed in inpatient/ambulatory settings in an acute care, academic, Magnet hospital. : There were no statistically significant relationships between nurse respondents' perceptions of work environment/support/encouragement and age or years of experience. However, there were significant differences between inpatient and ambulatory nurse responses in several key areas including job satisfaction, mentorship, and educational support. Overall, nurses reported feeling a lack of support and recognition from managers. Results provide evidence to support improved strategies to foster nurse retention.

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

Urinary tract infection in childhood: lower or upper level? DMSA scintigraphic validation of a new clinical risk index

Urinary tract infection in children can be limited most of time at the lower level of the urinary tractus but an extension to the upper level of the tractus should not be neglected due to the asymptomatic nature of the disease. In our study, we suggest a new graph to predict the probability of acute pyelonephritis only if the bacteriological urinary analyse were obtained in good conditions and without any treatment. In the other cases, a DMSA scintigram should be proposed at the earlier phase of the diagnosis not to underestimate the risk of asymptomatic pyelonephritis. (authors)

"Urinary Tract Infection"-Requiem for a Heavyweight.

Science.gov (United States)

Finucane, Thomas E

2017-08-01

"Urinary tract infection" ("UTI") is an ambiguous, expansive, overused diagnosis that can lead to marked, harmful antibiotic overtreatment. "Significant bacteriuria," central to most definitions of "UTI," has little significance in identifying individuals who will benefit from treatment. "Urinary symptoms" are similarly uninformative. Neither criterion is well defined. Bacteriuria and symptoms remit and recur spontaneously. Treatment is standard for acute uncomplicated cystitis and common for asymptomatic bacteriuria, but definite benefits are few. Treatment for "UTI" in older adults with delirium and bacteriuria is widespread but no evidence supports the practice, and expert opinion opposes it. Sensitive diagnostic tests now demonstrate that healthy urinary tracts host a ubiquitous, complex microbial community. Recognition of this microbiome, largely undetectable using standard agar-based cultures, offers a new perspective on "UTI." Everyone is bacteriuric. From this perspective, most people who are treated for a "UTI" would probably be better off without treatment. Elderly adults, little studied in this regard, face particular risk. Invasive bacterial diseases such as pyelonephritis and bacteremic bacteriuria are also "UTIs." Mindful decisions about antibiotic use will require a far better understanding of how pathogenicity arises within microbial communities. It is likely that public education and meaningful informed-consent discussions about antibiotic treatment of bacteriuria, emphasizing potential harms and uncertain benefits, would reduce overtreatment. Emphasizing the microbiome's significance and using the term "urinary tract dysbiosis" instead of "UTI" might also help and might encourage mindful study of the relationships among host, aging, microbiome, disease, and antibiotic treatment. © 2017, Copyright the Author Journal compilation © 2017, The American Geriatrics Society.

Assessing glomerular filtration rate (GFR) in critically ill patients with acute kidney injury - true GFR versus urinary creatinine clearance and estimating equations

Science.gov (United States)

2013-01-01

Introduction Estimation of kidney function in critically ill patients with acute kidney injury (AKI), is important for appropriate dosing of drugs and adjustment of therapeutic strategies, but challenging due to fluctuations in kidney function, creatinine metabolism and fluid balance. Data on the agreement between estimating and gold standard methods to assess glomerular filtration rate (GFR) in early AKI are lacking. We evaluated the agreement of urinary creatinine clearance (CrCl) and three commonly used estimating equations, the Cockcroft Gault (CG), the Modification of Diet in Renal Disease (MDRD) and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations, in comparison to GFR measured by the infusion clearance of chromium-ethylenediaminetetraacetic acid (51Cr-EDTA), in critically ill patients with early AKI after complicated cardiac surgery. Methods Thirty patients with early AKI were studied in the intensive care unit, 2 to 12 days after complicated cardiac surgery. The infusion clearance for 51Cr-EDTA obtained as a measure of GFR (GFR51Cr-EDTA) was calculated from the formula: GFR (mL/min/1.73m2) = (51Cr-EDTA infusion rate × 1.73)/(arterial 51Cr-EDTA × body surface area) and compared with the urinary CrCl and the estimated GFR (eGFR) from the three estimating equations. Urine was collected in two 30-minute periods to measure urine flow and urine creatinine. Urinary CrCl was calculated from the formula: CrCl (mL/min/1.73m2) = (urine volume × urine creatinine × 1.73)/(serum creatinine × 30 min × body surface area). Results The within-group error was lower for GFR51Cr-EDTA than the urinary CrCl method, 7.2% versus 55.0%. The between-method bias was 2.6, 11.6, 11.1 and 7.39 ml/min for eGFRCrCl, eGFRMDRD, eGFRCKD-EPI and eGFRCG, respectively, when compared to GFR51Cr-EDTA. The error was 103%, 68.7%, 67.7% and 68.0% for eGFRCrCl, eGFRMDRD, eGFRCKD-EPI and eGFRCG, respectively, when compared to GFR51Cr-EDTA. Conclusions The study

Albuminuria and a low estimated glomerular filtration rate (eGFR) are widely recognized indices of kidney dysfunction and have been linked to cardiovascular events, including stroke. We evaluated albuminuria, measured using the urinary albumin/creatinine ratio (UACR), and the eGFR in the acute phase of ischaemic stroke, and investigated the clinical characteristics of ischaemic stroke patients with and those without kidney dysfunction. The study included 422 consecutive patients admitted between June 2010 and May 2012. General blood and urine examinations were performed at admission. Kidney dysfunction was defined as a low eGFR (high albuminuria (≥30 mg/g creatinine), or both. Neurological severity was evaluated using the National Institutes of Health Stroke Scale (NIHSS) at admission and the modified Rankin scale (mRS) at discharge. A poor outcome was defined as a mRS score of 3-5 or death. The impacts of the eGFR and UACR on outcomes at discharge were evaluated using multiple logistic regression analysis. Kidney dysfunction was diagnosed in 278 of the 422 patients (65.9%). The eGFR was significantly lower and UACR was significantly higher in patients with a poor outcome than in those with a good outcome. In multivariate analyses performed after adjusting for confounding factors, UACR >31.2 mg/g creatinine (OR, 2.58; 95% CI, 1.52-4.43; P = 0.0005) was independently associated with a poor outcome, while a low eGFR was not associated. A high UACR at admission may predict a poor outcome at discharge in patients with acute ischaemic stroke. © 2016 Asian Pacific Society of Nephrology.

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

Full Text Available Introduction: Urinary tract infections (UTI are a major public health concern in developing countries. Most UTIs are caused by E. coli, accounting for up to 90% of community-acquired UTIs (CAUTI. Recurrent UTI is considered as a major risk factor for urolithiasis. Virulence factors like adhesins and biofilm have been extensively studied by authors on UPEC isolated from recurrent UTI.The studies on isolates from infection stones in kidney are scanty . In a prospective study, we aimed to determine the expression of Haemagglutinins, (Type 1 and P fimbriae , Biofilm production and resistance pattern to common antibiotics of Uropathogenic E.coli (UPEC isolates from Community acquired Acute Urinary Tract Infection(CAUTI and Urolithiasis. Materials and Methods: A total of 43 UPEC isolates , 23 mid-stream urine (MSU samples from patients with CAUTI attending Out Patient Departments and 20 from renal calculi of urolithiasis patients at the time of Percutaneous nephrolithostomy (PCNL were included in the study and the expression of Haemagglutinins,(Type 1 and P fimbriae , Biofilm production and resistance pattern to common antibiotics was assessed. Results: A total of 43 UPEC isolates 23 from CAUTI and 20 from renal calculi were tested for production of biofilm and hemagglutinins. In CAUTI, biofilm producers were 56.52% and hemagglutinins were detected in all isolates 100%. In urolithiasis, biofilm producers were 100% but hemagglutinins were detected only in 70% of isolates. All isolates were resistant to multiple antibiotics used. CAUTI isolates were susceptible to 3 rd generation cephalosporins, whereas urolithiasis isolates were resistant to 3 rd generation cephalosporins and 25% were Extended Spectrum Beta Lactamases ESBL producers. Conclusions: HA mediated by type 1 fimbriae plays an important role in CAUTI (P < 0.001 highly significant, whereas, in chronic conditions like urolithiasis, biofilm plays an important role in persistence of infection and

The clinical syndromes comprising urinary tract infection (UTI) continue to exert significant impact on millions of patients worldwide, most of whom are otherwise healthy women. Antibiotic therapy for acute cystitis does not prevent recurrences, which plague up to one fourth of women after an initial UTI. Rising antimicrobial resistance among uropathogenic bacteria further complicates therapeutic decisions, necessitating new approaches based on fundamental biological investigation. In this review, we highlight contemporary advances in the field of UTI pathogenesis and how these might inform both our clinical perspective and future scientific priorities.

Whole body and regional retention of sup(99m)Tc-labeled pyrophosphate at 24 hours: Physiological basis of the method for assessing the metabolism of bone in disease

Energy Technology Data Exchange (ETDEWEB)

Martin, P.; Schoutens, A.; Manicourt, D.; Bergmann, P.; Fuss, M.; Verbanck, M.

1983-01-01

The retention of sup(99m)Tc-labeled pyrophosphate (PPi) at 24 h was measured in 235 patients, 119 of whom had a normal bone metabolism. The mean retention in the group of normal subjects is 52% of the injected dose. Reproducibility of the measurement in a given person is 5.5% coefficient of variation (CV). The value was higher in males and higher with increasing age, especially in cortical bone. Retention increases slowly with the decrease in glomerular filtration rate (GFR) between 50 and 120 ml/min; it rises very rapidly with values below 50 ml/min. The slowing down of the GFR with age does not account for the increase in PPi retention with age. When expressed as a percentage of the expected value for sex and age, retention is frequently low in osteoporosis, more so when urinary hydroxyproline is low; it is normal or high in osteomalacia, and in some cases rises after vitamin D treatment is started; it is high in hyperparathyroidism. The PPi retention is correlated with bone calcium accretion rate, alkaline phosphatase level, and above all, the urinary hydroxyproline level. The lower the bone mineralization (Ca/hydroxyproline ratio in biopsy), the higher the retention value. We conclude that the PPi retention is an index of bone metabolism when GFR is higher than 50 ml/min. It allows for classification of metabolic bone diseases according to the bone turnover rate. It has the advantage over the usual biologic examinations in that it affords better observation of highly localized bone disorders and can be used in combination with a morphologic record, the bone scintigraphy.

Acute kidney injury (AKI) is a common complication after coronary angiography. Early biomarkers of this disease are needed since increase in serum creatinine levels is a late marker. To assess the usefulness of urinary kidney injury molecule-1 (uKIM-1), neutrophil gelatinase-associated lipocalin (uNGAL) and liver-type fatty acid-binding protein (uL-FABP) for early detection of AKI in these patients, comparing their performance with another group of cardiac surgery patients. Biomarkers were measured in 193 patients, 12 h after intervention. In the ROC analysis, AUC for KIM-1, NGAL and L-FABP was 0.713, 0.958 and 0.642, respectively, in the coronary angiography group, and 0.716, 0.916 and 0.743 in the cardiac surgery group. Urinary KIM-1 12 h after intervention is predictive of AKI in adult patients undergoing coronary angiography, but NGAL shows higher sensitivity and specificity. L-FABP provides inferior discrimination for AKI than KIM-1 or NGAL in contrast to its performance after cardiac surgery. This is the first study showing the predictive capacity of KIM-1 for AKI after coronary angiography. Further studies are still needed to answer relevant questions about the clinical utility of biomarkers for AKI in different clinical settings.

Diagnosis and treatment of acute low back pain.

Science.gov (United States)

Casazza, Brian A

2012-02-15

Acute low back pain is one of the most common reasons for adults to see a family physician. Although most patients recover quickly with minimal treatment, proper evaluation is imperative to identify rare cases of serious underlying pathology. Certain red flags should prompt aggressive treatment or referral to a spine specialist, whereas others are less concerning. Serious red flags include significant trauma related to age (i.e., injury related to a fall from a height or motor vehicle crash in a young patient, or from a minor fall or heavy lifting in a patient with osteoporosis or possible osteoporosis), major or progressive motor or sensory deficit, new-onset bowel or bladder incontinence or urinary retention, loss of anal sphincter tone, saddle anesthesia, history of cancer metastatic to bone, and suspected spinal infection. Without clinical signs of serious pathology, diagnostic imaging and laboratory testing often are not required. Although there are numerous treatments for nonspecific acute low back pain, most have little evidence of benefit. Patient education and medications such as nonsteroidal anti-inflammatory drugs, acetaminophen, and muscle relaxants are beneficial. Bed rest should be avoided if possible. Exercises directed by a physical therapist, such as the McKenzie method and spine stabilization exercises, may decrease recurrent pain and need for health care services. Spinal manipulation and chiropractic techniques are no more effective than established medical treatments, and adding them to established treatments does not improve outcomes. No substantial benefit has been shown with oral steroids, acupuncture, massage, traction, lumbar supports, or regular exercise programs.

Acute kidney injury (AKI) is a frequent complication in cirrhotic patients. As serum creatinine is a poor marker of renal function in this population, we aimed to study the utility of several biomarkers in this context. A prospective study was conducted in hospitalized patients with decompensated cirrhosis. Serum creatinine (SCr), Cystatin C (CystC), NGAL and urinary NGAL, KIM-1, protein, albumin and sodium were measured on three separate occasions. Renal resistive index (RRI) was obtained. We analyzed the value of these biomarkers to determine the presence of AKI, its etiology [prerenal, acute tubular necrosis (ATN), or hepatorenal (HRS)], its severity and a composite clinical outcome at 30 days (death, dialysis and intensive care admission). We included 105 patients, of which 55 had AKI. SCr, CystC, NGAL (plasma and urinary), urinary sodium and RRI at inclusion were independently associated with the presence of AKI. SCr, CystC and plasma NGAL were able to predict the subsequent development of AKI. Pre-renal state showed lower levels of SCr, NGAL (plasma and urinary) and RRI. ATN patients had high levels of NGAL (plasma and urinary) as well as urinary protein and sodium. HRS patients presented an intermediate pattern. All biomarkers paralleled the severity of AKI. SCr, CystC and plasma NGAL predicted the development of the composite clinical outcome with the same performance as the MELD score. In patients with decompensated cirrhosis, early measurement of renal biomarkers provides valuable information on AKI etiology. It could also improve AKI diagnosis and prognosis.

In 30% of children with urinary tract anomalies, urinary tract infection (UTI) can be the first sign. Failure to identify patients at risk can result in damage to the upper urinary tract. To provide recommendations for the diagnosis, treatment, and imaging of children presenting with UTI. The recommendations were developed after a review of the literature and a search of PubMed and Embase. A consensus decision was adopted when evidence was low. UTIs are classified according to site, episode, symptoms, and complicating factors. For acute treatment, site and severity are the most important. Urine sampling by suprapubic aspiration or catheterisation has a low contamination rate and confirms UTI. Using a plastic bag to collect urine, a UTI can only be excluded if the dipstick is negative for both leukocyte esterase and nitrite or microscopic analysis is negative for both pyuria and bacteriuria. A clean voided midstream urine sample after cleaning the external genitalia has good diagnostic accuracy in toilet-trained children. In children with febrile UTI, antibiotic treatment should be initiated as soon as possible to eradicate infection, prevent bacteraemia, improve outcome, and reduce the likelihood of renal involvement. Ultrasound of the urinary tract is advised to exclude obstructive uropathy. Depending on sex, age, and clinical presentation, vesicoureteral reflux should be excluded. Antibacterial prophylaxis is beneficial. In toilet-trained children, bladder and bowel dysfunction needs to be excluded. The level of evidence is high for the diagnosis of UTI and treatment in children but not for imaging to identify patients at risk for upper urinary tract damage. In these guidelines, we looked at the diagnosis, treatment, and imaging of children with urinary tract infection. There are strong recommendations on diagnosis and treatment; we also advise exclusion of obstructive uropathy within 24h and later vesicoureteral reflux, if indicated. Copyright © 2014 European

Urinary Concentrating Ability in Women with Asymptomatic Bacteriuria in Pregnancy

Science.gov (United States)

Williams, G. L.; Campbell, H.; Davies, K. J.

1969-01-01

The incidence of impaired renal concentrating ability in pregnant women with asymptomatic significant bacteriuria is significantly less than previously reported when osmolality readings are performed on every urine specimen obtained during the 24 hours' deprivation of fluids. The concentrating defect is more considerable as pregnancy progresses. The lower the maximum urinary osmolality the more difficult is the treatment of the patient, and the higher the incidence of acute pyelonephritis. PMID:5792611

Anatomy and Physiology of the Urinary Tract: Relation to Host Defense and Microbial Infection.

Hickling, Duane R; Sun, Tung-Tien; Wu, Xue-Ru

2015-08-01

The urinary tract exits to a body surface area that is densely populated by a wide range of microbes. Yet, under most normal circumstances, it is typically considered sterile, i.e., devoid of microbes, a stark contrast to the gastrointestinal and upper respiratory tracts where many commensal and pathogenic microbes call home. Not surprisingly, infection of the urinary tract over a healthy person's lifetime is relatively infrequent, occurring once or twice or not at all for most people. For those who do experience an initial infection, the great majority (70% to 80%) thankfully do not go on to suffer from multiple episodes. This is a far cry from the upper respiratory tract infections, which can afflict an otherwise healthy individual countless times. The fact that urinary tract infections are hard to elicit in experimental animals except with inoculum 3-5 orders of magnitude greater than the colony counts that define an acute urinary infection in humans (105 cfu/ml), also speaks to the robustness of the urinary tract defense. How can the urinary tract be so effective in fending off harmful microbes despite its orifice in a close vicinity to that of the microbe-laden gastrointestinal tract? While a complete picture is still evolving, the general consensus is that the anatomical and physiological integrity of the urinary tract is of paramount importance in maintaining a healthy urinary tract. When this integrity is breached, however, the urinary tract can be at a heightened risk or even recurrent episodes of microbial infections. In fact, recurrent urinary tract infections are a significant cause of morbidity and time lost from work and a major challenge to manage clinically. Additionally, infections of the upper urinary tract often require hospitalization and prolonged antibiotic therapy. In this chapter, we provide an overview of the basic anatomy and physiology of the urinary tract with an emphasis on their specific roles in host defense. We also highlight the

In the historical series, the diagnostic yield of lumbosacral magnetic resonance imaging to rule out occult spinal dysraphism (or occult myelodysplasia), requested by paediatric urology, ranged from 2% to 15%. The aim of this study was to define our cost-effectiveness in children with urinary symptoms and to define endpoints that increase the possibility of finding occult spinal dysraphism. A screening was conducted on patients with urinary dysfunction for whom an magnetic resonance imaging was requested by the paediatric urology clinic, for persistent symptoms after treatment, voiding dysfunction or other clinical or urodynamic findings. We analysed clinical (UTI, daytime leaks, enuresis, voiding dysfunction, urgency, renal ultrasonography, lumbosacral radiography, history of acute urine retention, skin stigma and myalgia) and urodynamic endpoints (hyperactivity or areflexia, voiding dysfunction, interrupted pattern, accommodation value and maximum flow). A univariate analysis was conducted with SPSS 20.0. We analysed 21 patients during the period 2011-2015. The median age was 6 years (3-10). Three patients (14.3%) had occult spinal dysraphism: one spinal lipoma, one filum lipomatosus and one caudal regression syndrome with channel stenosis. The endpoints with statistically significant differences were the myalgias and the history of acute urine retention (66.7% vs. 5.6%, P=.04; OR= 34; 95%CI: 1.5-781 for both endpoints). The diagnostic yield of magnetic resonance imaging requested for children with urinary dysfunctions without skin stigma or neuro-orthopaedic abnormalities is low, although nonnegligible. In this group, the patients with a history of acute urine retention and muscle pain (pain, «cramps») can experience a greater diagnostic yield or positive predictive value. Copyright © 2017 AEU.

Merrick, Gregory S.; Butler, Wayne M.; Lief, Jonathan H.; Dorsey, Anthony T.

2000-01-01

Purpose: To report the short-term urinary morbidity for prostate brachytherapy patients without a preimplant history of a transurethral resection of the prostate gland and who received prophylactic and prolonged α-blockers. α-blockers may decrease radiation-induced urethritis and increase urinary flow. Multiple clinical and treatment parameters were evaluated to identify factors associated with increased acute urinary morbidity. Materials and Methods: One hundred seventy consecutive patients without a prior history of a transurethral resection of the prostate gland underwent transperineal ultrasound guided prostate brachytherapy for clinical T1c-T3a carcinoma of the prostate gland. For all patients, an α-blocker was initiated prior to implantation and continued at least until the international prostate symptom score (IPSS) returned to baseline levels. Clinical parameters evaluated for short-term urinary morbidity included patient age, clinical T stage, preimplant IPSS (obtained within 3 weeks of implantation), and prostate ultrasound volume. Treatment parameters included the utilization of neoadjuvant hormonal manipulation, the utilization of moderate dose external beam radiation therapy before implantation, the choice of isotope, the urethral dose, the total implant activity in millicuries, and a variety of dosimetric quality indicators (D 90 and V 100 /V 150 /V 200 ). Catheter dependency and the duration of α-blocker dependency was also evaluated. On average, 11.2 IPSS surveys were obtained for each patient. Results: One hundred fifty of the 170 patients (88.2%) had the urinary catheter permanently removed on day 0. Only one patient required an urinary catheter for > 5 days. Two patients (1.2%) required a subsequent transurethral resection of the prostate gland because of prolonged obstructive/irritative symptoms. To date, no patient has developed an urinary stricture or urinary incontinence. The IPS score on average peaked at 2 weeks following implantation

The objective of the present paper was to review the use of the dimercaptosuccinic acid (DMSA) scan in urinary tract infection at British Columbia's Children's Hospital to determine the frequency of cortical defects and the association between vesico-ureteric reflux and the presence of cortical defects in children with urinary tract infection. A total of 129 consecutive children with a urinary tract infection referred for a DMSA scan in a 2-year period (January 1992-January 1994) were retrospectively studied. The results were analysed in terms of kidneys, and the incidence of cortical defects was determined. Eighty-eight patients (68%) had a radiographic micturating cysto-urethrogram within 6 months of the DMSA scan, and in this group the relationship of defects with vesico-ureteric reflux was determined. Overall, 81/258 (31%) of kidneys had a cortical defect on a DMSA scan. Of those who had a micturating cysto-urethrogram, 53/176 (30%) kidneys had vesico-ureteric reflux, and of those that had reflux, 21/53 (40%) had a cortical defect on a DMSA scan. In the group of children without reflux, 38/123 (31%) had a cortical defect. Renal cortical scan defects are common findings in paediatric urinary infection, and frequently occur in the absence of vesico-ureteric reflux. These defects represent either established scars or acute pyelonephritis that can proceed to scarring. The micturating cysto-urethro-gram alone is insufficient as a screening modality to identify those kidneys at risk of renal scarring. Copyright (1998) Blackwell Science Pty Ltd

2013-11-01

Full Text Available The aim of the present study is to describe the type and frequency of bladder dysfunction in a series of female patients with multiple sclerosis (MS from Rio de Janeiro, and analyze the role of the urologist in the multidisciplinary team. A team of urologists and a neurologist from the Hospital da Lagoa, Rio de Janeiro, Brazil, interviewed female patients with MS about illness onset, urologic follow-up since diagnosis, current stage of the disease and current urological symptoms. The interview was followed by an urodynamic testing, ultrasound of the urinary tract and urinalysis. Data resulting from the interviews and exam results were gathered and submitted to statistical evaluation. Sixty one patients were evaluated, with average age of 41.4 years. Urinary symptoms such as urinary incontinence, urinary hesitancy, urinary retention, urinary urgency and incomplete bladder emptying were reported in 44% of patients as initial signs of MS disease. Mean disease duration was 8 years and all patients (100% with the primary progressive form of the disease and 63.5% with the relapsing-remitting presentation had urological symptoms. Analysis of complementary exams showed that 37.7% of urinalysis, 8.2% of the urinary tract ultrasound exams and 66.7% of the urodynamic evaluations were abnormal and the most frequent abnormality were overactive neurogenic bladder. Only 4 patients (6.6% had seen an urologist during the course of their disease and only 1.6% had performed an urodynamic evaluation. This study shows a high prevalence (68% of urinary dysfunction in a female population with MS. Urologic care should be part of the multidisciplinary team since the beginning of the disease. An urodynamic evaluation and simple urinalysis should be included in the routine testing during disease follow-up due to the high incidence of neurogenic bladder and other urologic complications.

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

2014-01-01

Urethral calculi are rare forms of urolithiasis. Majority of the calculi are migratory from urinary bladder or upper urinary tract. Primary urethral calculi usually occur in presence of urethral stricture or diverticulum. In this article we report a case of a giant posterior urethral calculus measuring 7x3x2 cm in a 47 years old male. Patient presented with acute retention of urine which was preceded by burning micturition and dribbling of urine for one week. The calculus was pushed in to the bladder through the cystoscope and was removed by suprapubic cystolithotomy.

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

Full Text Available Neurogenic hyperactiv e bladder in different clinical variations is a characteristic com plication of restorativ e and residual periods of ischemic stroke and an important diagnostic criterion in vascular dementia. Mechanisms of formation of individual symptoms included in this syndrome is due to ischemic damage to cortical, subcortical and brainstem (the nucleus of Barrington centres of urination and associative areas of the brain, and the functional dissociation of these structures due to demyelination of the Central conductors of the afferent and efferent impulses. As a result of deficit of cerebral effects (such as brake and activating, is a violation of the implementation of the reflexes of urination (including carrying out continence, ongoing spinal (sympathetic, parasympathetic and somatic. The article presents a new concept of formation of the syndrome of hyperactive bladder on the basis of violations of the implementation of the 4 reflexes of urination, which provides the normal retention of urine and are responsible for the accumulation function of the bladder. First we analyzed the main point of application of drugs of anticholinergic and sympathomimetic actions in the reflexes of urination and mechanisms of restoration of function of the lower urinary tract in patients with acute and chronic v ascular diseases of the brain.

Purpose: The nonthermal irreversible electroporation (NTIRE) is a novel potential ablation modality for renal masses. The aim of this study was the first evaluation of NTIRE's effects on the renal urine-collecting system using intravenous urography (IVU) and urinary cytology in addition to histology and magnetic resonance imaging (MRI). Methods: Eight percutaneous NTIRE ablations of the renal parenchyma, including the calyxes or pelvis, were performed in three male swine. MRI, IVU, histology, and urinary cytology follow-ups were performed within the first 28 days after treatment. Results: MRI and histological analysis demonstrated a localized necrosis 7 days and a localized scarification of the renal parenchyma with complete destruction 28 days after NTIRE. The urine-collecting system was preserved and showed urothelial regeneration. IVU and MRI showed an unaltered normal morphology of the renal calyxes, pelvis, and ureter. A new urinary cytology phenomenon featured a temporary degeneration by individual vacuolization of detached transitional epithelium cells within the first 3 days after NTIRE. Conclusions: This first urographical, urine-cytological, and MRI evaluation after porcine kidney NTIRE shows multifocal parenchyma destruction while protecting the involved urine-collecting system with regenerated urothelial tissue. NTIRE could be used as a targeted ablation method of centrally located renal masses.

Acute uncomplicated lower urinary tract infections (UTI) and vulvovaginal candidiasis (VVC) both occur frequently in women. Although VVC is believed to commonly occur after antibiotic therapy, few studies have demonstrated this association. Thus, the aim of the study was to estimate the prevalence of colonization by Candida spp. and VVC after norfloxacin (NOR) use for UTI and the effects on the vaginal microbiota and inflammatory process. This was a prospective cohort study of women with culture-proven UTI who were treated with NOR (antibiotic group). The control group consisted of women with noninfectious diseases or in preventive care. Candida vaginal infections were monitored both clinically and mycologically at baseline and at the follow-up evaluation. All women showed UTI remission after NOR treatment, and no woman in either group, antibiotic and control, showed symptoms of VVC. Both groups showed similar ratios of a positive Candida culture at baseline (6.7 % and 12.8 %, respectively) and at follow-up (3.3 % and 8.5 %, respectively) (p = 0.2768 and p = 0.5035, respectively). The antibiotic group showed no increased risk of Candida colonization or VVC after NOR treatment compared with the control group [odds ratio (OR) 0.556, 95 % confidence interval (CI) 0.2407-10.05]. NOR was effective for UTI treatment, did not increase the risk of vaginal colonization by Candida or VVC, and did not lead to major disturbances of the vaginal microbiota.

The purpose of this study was to evaluate the usefulness of 99m Tc DMSA scintigraphy on the diagnosis of a renal scar in children with urinary tract infections. Eighty three patients were included in this study, who were diagnosed as the urinary tract infection on the basis of symptom, urinalysis and urine culture. 99m Tc DMSA scintigraphy and voiding cystoureterography were performed within 7days before the treatment in all patients. We classified the scintigraphic findings as follow s : 1 ; a large hypoactive upper of lower pole. 2 ; a small hypoactive area. 3 ; single defect resulting in localized deformity of the outlines. 4 ; deformed outlines in a small or normal sized kidney. 5 ; multiple defects. 6 ; diffuse hypoactive kidney without regional impairment. Follow-up scintigraphy was done at least 6 months after the initial study. When the abnormality on the initial scintigraphy was not completely resolved on the follow-up scan, the lesion was defined as containing a scar. One hundred and fifteen renal units of 166 units(69.3%) showed abnormal findings on the DMSA scintigraphy. 65 units(56.5%) was diagnosed as containing renal scars in follow-up scintigraphies. Incidences of renal scar among renal units showing pattern 3, 4 and 5 on the initial scan was 75%, 78% and 78%, respectively. Whereas many of renal units showing 1, 2 and 6 pattern were recovered(65%, 76%, 50%). Sensitivity, specificity and accuracy of pattern-based DMSA scintigraphic findings on the diagnosis of renal scar was 76.9%, 85.1% and 81.9%, respectively. VUR was significantly associated with the renal scar when the initial DMSA shows unrecoverable findings(pattern 3, 4, 5). Odds ratio of the renal scar in a kidney showing unrecoverable initial scintigraphic findings was 19.1. Odds ratio in a kidney with mild or moderate-to-severe VUR was 3.5 and 14.4 respectively. In the urinary tract infection, renal scar was significantly developed in a kidney showing unrecoverable findings on the initial

A recent survey indicated that high-dose vitamin A supplements (HD-VAS) had no apparent effect on vitamin A (VA) status of Zambian children <5 y of age. To explore possible reasons for the lack of response to HD-VAS among Zambian children, we quantified the absorption, retention, and urinary elimination of either a single HDVAS (60 mg) or a smaller dose of stable isotope (SI)-labeled VA (5 mg), which was used to estimate VA pool size, in 3-4 y old Zambian boys (n = 4 for each VA dose). A 25 nCi tracer dose of [{sup 14}C{sub 2}]-labeled VA was co-administered with the HD-VAS or SI-labeled VA, and 24-hr stool and urine samples were collected for 3 and 7 consecutive days, respectively, and 24-hr urine samples at 4 later time points. Accelerator Mass Spectrometry (AMS) was used to measure the cumulative excretion of {sup 14}C in stool and urine 3d after dosing to estimate, respectively, absorption and retention of the VAS and SI-labeled VA. The urinary elimination rate (UER) was estimated by plotting {sup 14}C in urine vs. time, and fitting an exponential equation to the data. Estimates of mean absorption, retention and the UER were 83.8 {+-} 7.1%, 76.3 {+-} 6.7%, and 1.9 {+-} 0.6%/d, respectively, for the HD-VAS and 76.5 {+-} 9.5%, 71.1 {+-} 9.4%, and 1.8 {+-} 1.2%/d, respectively for the smaller dose of SI-labeled VA. Estimates of absorption, retention and the UER did not differ by size of the VA dose administered (P=0.26, 0.40, 0.88, respectively). Estimated absorption and retention were negatively associated with reported fever (P=0.011) and malaria (P =0.010). HD-VAS and SI-labeled VA were adequately absorbed, retained and utilized in apparently healthy Zambian preschool-age boys, although absorption and retention may be affected by recent infections.

Bilateral acute iris transillumination: Case report

Directory of Open Access Journals (Sweden)

Cumali Degirmenci

2016-04-01

Full Text Available Bilateral acute iris transillumination (BAIT is a recently defined disease characterized with bilateral acute, severe pigment dispersion of iris and pupil sphincter paralysis. The etiopathogenesis of the disease is unknown, but antibiotics such as moxifloxacin, clarithromycin, viral infections, and fumigation therapies were considered as probable etiologic factors. A 33-year-old female was referred to our clinic for acute iridocyclitis refractory to azathioprine, colchicum and corticosteroid treatments. Ophthalmic examination revealed bilateral pigment dispersion, significant iris transillumination, heavy pigment deposition in iridocorneal angle, and elevated intraocular pressure. Upon systemic evaluation she was found to have bacterial urinary tract infection. BAIT is an important cause of pigment dispersion and clinicians must be vigilant for this condition to avoid unnecessary diagnostic tests and treatment.

Acute uncomplicated cystitis (AUC) and acute uncomplicated pyelonephritis (AUP) are two common urinary tract infections (UTI) in otherwise healthy young women. Both weaknesses of the mucosal barrier and specific factors of uropathogenic bacteria must be present before the bacteria can adhere to the urothelium and give rise to an infection. These circumstances are also of relevance in recurrent UTI. Antibiotic treatment of AUC and AUP is based on the guidelines of the Infectious Diseases Society of America (IDSA). For the prevention of recurrent UTI, antibiotics, functional foods, injections, probiotic agents and other measures are recommended with varying potential for success.

Thirty-three antepartum patients with urinary tract infections underwent urologic evaluation as soon as the infection had been successfully treated. The evaluation included history of voiding habits, cystometry, urethral calibration and cystourethroscopy. A second phase of the urologic evaluation included an excretory urogram and repeat cystometry 10-12 weeks postpartum. Sixty percent had a history of infrequent voiding, and 90% of them had a bladder capacity greater than 450 mL. Forty-one percent of the patients had a normal bladder capacity (less than 450 mL), and 85% of this group did not have any history of infrequent voiding. The radiographic evaluation postpartum in 18 of 33 patients revealed major abnormalities in 50%. These abnormalities were seen as often and were as significant in women with asymptomatic bacteriuria as in those who presented with acute pyelonephritis. The results suggest that the large bladder seen in pregnant women may be secondary to the chronic, unphysiologic habit of infrequent voiding. Furthermore, this study reinforced the fact that most pregnant women with urinary tract infection have preexisting chronic bladder or renal abnormalities that predispose them to infection. Those at risk should be identified early through a careful history and urinalysis to determine which ones need urinary prophylaxis during pregnancy. Postpartum urologic investigation should be carried out to identify any structural or functional problems; understanding them is helpful in present and future management.

Background and purpose: To describe the incidence of urinary incontinence among prostate cancer patients treated with external beam radiotherapy (RT) and to investigate associated risk factors. Patients and methods: One thousand and hundred ninety-two patients with ≥24 months follow-up were the subjects of this series. All patients received between 50 and 72 Gy in 20-37 fractions (median 66 Gy/33). Post-RT urinary incontinence was scored by direct patient interviewing according to the modified RTOG/SOMA scale: Grade 1-occasional use of incontinence pads, Grade 2-intermittent use of incontinence pads, Grade 3-persistent use of incontinence pads, and Grade 4-permanent catheter. Risk-factors investigated were: age, diabetes, TURP prior to RT, elapsed time from TURP to RT, clinical stage, RT dose and presence of Grade ≥2 acute GU and GI toxicity. Non-parametric, actuarial univariate (Kaplan-Meier) and multivariate tests (MVA, Cox regression) were performed. Results: Median follow-up for the group is 52 months (24-109). Thirty-four patients (2.9%) had incontinence prior to RT, which was more common in TURP patients (7.8% vs 1.6% P<0.001). These are excluded from further analysis. Fifty-seven patients (4.9%) developed Grade 1 incontinence, 7 (0.6%) Grade 2, and 7 (0.6%) Grade 3. There was no Grade 4 incontinence. Actuarial rates for Grade ≥1 and ≥2 incontinence at 5 years are 7 and 1.7%, respectively. Risk factors on MVA associated with the development of Grade 1 or worse incontinence are pre-RT TURP (5-year rates 10% vs 6%, P=0.026), presence of Grade ≥2 acute GU toxicity (5-year rates 11% vs 5%, P=0.002). Age, diabetes, clinical stage, elapsed time from TURP to RT, RT dose or fraction size, acute GI toxicity were not significant. Patients who underwent post-RT TURP or dilatation for obstructive symptoms (4.3%), were more likely to develop Grade 2-3 incontinence (5-year rate 8 vs 1.5%, P=0.0015). Conclusions: Grade 2 or greater urinary incontinence is rare

The aim of the case report is presentation of unusual and heavy clinical course of pyelonephritis with renal tissue necrosis in a child with urinary tract malformation. Nine month old girl was admitted to hospital in heavy clinical status due to pyelonephritis--urosepsis. It was complicated by acute renal insufficiency. Patient was treated by broad-spectrum antibiotics and parenteral nutrition. She was feverish for 14 days. Computed tomography done in order to exclude abdominal abscess showed massive renal tissue necrosis of on both sides. Antibiotic treatment was successful after 6 weeks. Urological evaluation revealed bilateral vesico-ureteral refluxes grade IV. Scintigraphy showed multiple scars. Patient was treated Deflux injections (twice). We noted 5 urinary tract recurrences despite antibiotic profilaxis. GFR of 75 ml/min/1.73 m2 was estimated at age of 16 m. Immunodeficiency or malignancy as background of clinical course were excluded. The case we describe presents severe clinical course of pyelonephritis due to complex urinary tract malformation that is to be considered despite based on modern publications "sparing" strategies of diagnosis and profilaxis in urinary tract malformations.

Acute tubular necrosis (ATN) describes a form of intrinsic acute kidney injury (AKI) that results from persistent hypoperfusion and subsequent activation of the immune system. A glycosylated transmembrane protein, CD147/basigin, is involved in the pathogenesis of renal ischemia and fibrosis. The present study investigated whether CD147 can reflect pathological features and renal dysfunction in patients with AKI. Plasma and spot urine samples were collected from 24 patients (12 controls and 12 with ATN) who underwent renal biopsy between 2008 and 2012. In another study, patients undergoing open surgery to treat abdominal aortic aneurysms (AAAs) were enrolled in 2004. We collected urine and plasma samples from seven patients with AKI and 33 patients without AKI, respectively. In these experiments, plasma and urinary CD147, and urinary L-fatty acid-binding protein (L-FABP) levels were measured, and the former expression in kidneys was examined by immunostaining. In biopsy tissues of ATN with severe histological features, CD147 induction was strikingly present in inflammatory cells such as macrophages and lymphocytes in the injured interstitium, but not in damaged tubules representing atrophy. Both plasma and urinary CD147 levels were strikingly increased in ATN patients; both values showed greater correlations with renal dysfunction compared to urinary L-FABP. In patients who had undergone open AAA surgery, urinary and plasma CD147 values in AKI patients were significantly higher than in non-AKI patients at post-operative day 1, similar to the profile of urinary L-FABP. CD147 was prominent in its ability to detect AKI and may allow the start of preemptive medication.

2,3-Dimercaptosuccinic acid (DMSA) is a new orally active heavy metal chelator for the treatment of childhood Pb intoxication on an outpatient basis. The influence of DMSA, as well as other chelating agents, on gastrointestinal 203Pb absorption and whole-body 203 Pb retention was examined. Groups of Sprague-Dawley rats (230-260 g) were gavaged with a solution containing approximately 25 mg/kg Pb [as Pb(NO 3 )2] plus 15 microCi 203 Pb. Some groups were then immediately given 0.11 mmol/kg of either DMSA, CaNa2EDTA, D-penicillamine, or BAL by oral gavage, while other groups received the same drugs by ip injection. Control groups received solutions of the drug vehicles po or ip. Whole-body Pb retention and gastrointestinal Pb absorption (whole body retention + urinary Pb excretion) were significantly decreased in rats that received DMSA po. This finding implies that the use of DMSA to treat childhood lead intoxication on an outpatient basis is not associated with a risk for increased Pb absorption

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

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

This study aimed to determine the diagnostic and prognostic value of urinary biomarkers of intrinsic acute kidney injury (AKI) when patients were triaged in the emergency department. Intrinsic AKI is associated with nephron injury and results in poor clinical outcomes. Several urinary biomarkers have been proposed to detect and measure intrinsic AKI. In a multicenter prospective cohort study, 5 urinary biomarkers (urinary neutrophil gelatinase-associated lipocalin, kidney injury molecule-1, urinary liver-type fatty acid binding protein, urinary interleukin-18, and cystatin C) were measured in 1,635 unselected emergency department patients at the time of hospital admission. We determined whether the biomarkers diagnosed intrinsic AKI and predicted adverse outcomes during hospitalization. All biomarkers were elevated in intrinsic AKI, but urinary neutrophil gelatinase-associated lipocalin was most useful (81% specificity, 68% sensitivity at a 104-ng/ml cutoff) and predictive of the severity and duration of AKI. Intrinsic AKI was strongly associated with adverse in-hospital outcomes. Urinary neutrophil gelatinase-associated lipocalin and urinary kidney injury molecule 1 predicted a composite outcome of dialysis initiation or death during hospitalization, and both improved the net risk classification compared with conventional assessments. These biomarkers also identified a substantial subpopulation with low serum creatinine at hospital admission, but who were at risk of adverse events. Urinary biomarkers of nephron damage enable prospective diagnostic and prognostic stratification in the emergency department. Copyright © 2012 American College of Cardiology Foundation.

Urinary toxicity is common after low-dose-rate (LDR) brachytherapy, and the resolution of urinary toxicity is a concern. In particular, urinary frequency is the most common adverse event among the urinary toxicities. We have previously reported that approximately 70% of patients experience urinary frequency during the first 6 months after seed implantation. Most urinary adverse events were classified as Grade 1, and Grade 2 or higher adverse events were rare. The incidence of urinary retention was approximately 2-4%. A high International Prostate Symptom Score before seed implantation was an independent predictor of acute urinary toxicity of Grade 2 or higher. Several previous reports from the United States also supported this trend. In Japan, LDR brachytherapy was legally approved in 2003. A nationwide prospective cohort study entitled Japanese Prostate Cancer Outcome Study of Permanent Iodine-125 Seed Implantation was initiated in July 2005. It is an important issue to limit urinary toxicities in patients who undergo LDR brachytherapy. Copyright © 2015 American Brachytherapy Society. Published by Elsevier Inc. All rights reserved.

Upregulation of microRNA 142-3p in the peripheral blood and urinary cells of kidney transplant recipients with post-transplant graft dysfunction

T.D. Domenico

Full Text Available We analyzed microRNA (miR-142-3p expression in leucocytes of the peripheral blood and urinary sediment cell samples obtained from kidney transplant recipients who developed graft dysfunction. Forty-one kidney transplant recipients with kidney graft dysfunction and 8 stable patients were included in the study. The groups were divided according to histological analysis into acute rejection group (n=23, acute tubular necrosis group (n=18 and stable patients group used as a control for gene expression (n=8. Percutaneous biopsies were performed and peripheral blood samples and urine samples were obtained. miR-142-3p was analyzed by real-time polymerase chain reaction. The group of patients with acute tubular necrosis presented significantly higher expressions in peripheral blood (P<0.05 and urine (P<0.001 compared to the stable patients group. Also, in the peripheral blood, miR-142-3p expression was significantly higher in the acute tubular necrosis group compared to the acute rejection group (P<0.05. Urine samples of the acute rejection group presented higher expression compared to the stable patients group (P<0.001 but the difference between acute tubular necrosis and acute rejection groups was not significant in the urinary analyzes (P=0.079. miR-142-3p expression has a distinct pattern of expression in the setting of post-operative acute tubular necrosis after kidney transplantation and may potentially be used as a non-invasive biomarker for renal graft dysfunction.

Pediatric nuclear medicine, in order to survive, must be innovative in finding ways of competing with other pediatric imaging studies for better health care. In this study a group of thirty-one patients with urinary tract infection confirmed by clinical investigation, (fever, pain, ....ect), laboratory investigation (RBC and pus cell)and urine culture, were evaluate by nuclear medicine study. The aim of the study was to compare the diagnostic value of cortical scintigraphy using Tc 99m dimercaptosuccinic acid (Tc 99m -DMSA), with two other routine investigations; the intravenous urographic (IVU), and ultrasonography (US), for diagnosis of renal parenchymal abnormality in children. The Tc 99m -DMSA renal scan was utilized as the gold standard test for renal involvement. All patients had Tc 99m -DMSA renal scan, and US, and only 22 patients had contrast IVU. The Tc 99m -DMSA renal scan showed abnormality renal scanning in about 94% of patients, US abnormalities were detected in about 81% of patient, while the IVU detected defects in about 87%. Because the prevalence of upper UTI in children is high, Tc 99m -DMSA renal scan is undoubtedly the available tool for pediatriacicians as a guide in giving appropriate antibiotic therapy and to prevent further renal damage. The study concludes that, the renal cortical scintigraphy with Tc 99m -DMSA has been reported to be a useful children diagnostic study of acute parenchymal renal infections, moreover, is presently the method of choice to detect acute parenchymal infection.

A case of transient bladder dysfunction and urinary retention concomitant with herpes genitalis is presented. The protean manifestations of the herpes simplex virus, the similar neurotropic behavior of simplex and zoster, and the neurologic sequelae of the cutaneous simplex eruption are discussed. The possibility of sacral radiculopathy after herpes genitalis must be considered when evaluating acute or episodic neurogenic bladders.

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

Full Text Available Background: Community-onset urinary tract infections (CoUTIs are the most common bacterial infections, and a decline in antibiotic susceptibility causes many clinical challenges. Adequate empiric antibiotic treatment can decrease unnecessary hospital stays and complications, while reducing the antimicrobial resistance progression. Methods: From October 2014 to April 2015, we retrospectively enrolled patients who were at least 18 years old and required hospitalization for CoUTIs. Demographic variables of these patients, and uropathogens and their antimicrobial susceptibilities were evaluated. Results: In total, 457 patients were enrolled in this study. Their mean age was 71.9 years, and 35.2% of the patients were male. Escherichia coli (54.5% was the most common uropathogen, followed by Klebsiella pneumoniae (13.1%, Enterococcus spp. (7.1%, Pseudomonas aeruginosa (4.6%, and Proteus mirabilis (3.5%. Bacteremia was present in 25.2% of patients. Diabetes mellitus and acute kidney injury at admission were risk factors for CoUTIs with concomitant bacteremia. Among the UTI-associated bloodstream strains, E. coli (53.1% was also the most predominant pathogen, followed by K. pneumoniae (11.3%, Staphylococcus aureus (6.1%, and P. mirabilis (4.3%. The overall susceptibility of cefazolin was 62.8%, ceftriaxone 71.4%, ceftazidime 82.8%, flomoxef 82%, cefepime 94.5%, ampicillin–sulbactam 41.6%, piperacillin–tazobactam 85%, levofloxacin 65.2%, trimethoprim–sulfamethoxazole 61.5%, imipenem 92.3%, gentamicin 76.1%, and amikacin 97.5%. Cefazolin-susceptible isolates could be found more frequently among patients who are less than 65 years of age and without diabetes mellitus, had no UTI episode in the past year, and have no bacteremia risk. Patients with nasogastric tube retention more commonly experienced antimicrobial resistance to all the third-generation cephalosporins. Conclusion: Third-generation cephalosporins effectively treated Co

Investigations of nephrotoxicity caused by ionic and non-ionic contrast media in rats with previously damaged and not previously damaged kidneys and special view to urinary enzyme determinations

In this study ionic (meglumine amidotrizoate) and non-ionic contrast media (SHH 340 AB, Iohexol, Iopromide, Iosimide and Iopamidol) were tested for their nephrotoxicity in rats. During the experiment detections of urea nitrogen, serum creatinine and urinary enzymes as well as histological examinations of the kidneys were carried out for the diagnosis of acute renal damage. The results obtained in this study demonstrate that rats are not very sensitive to non-ionic contrast media with regard to kidney damage and determinations of urinary enzymes are valuable for the diagnosis of contrast media induced acute kidney damage in living animals.

Today, infection remains the most common disease of the urinary tract and constitutes almost 75% of patient problems requiring urologic evaluation. There have been several major factors responsible for our better understanding of the nature and pathophysiology of urinary tract infection. One has been quantitated urine bacteriology and another, the discovery that a significant part of the apparently healthy adult female population has asymptomatic bacteriuria. Abnormal conditions such as neurogenic bladder, bladder malignancy, prolonged catheter drainage and reflux, altered host resistance, diabetes mellitus, and urinary tract obstruction, as well as pregnancy, may either predispose to or be implicated in the pathogenesis of urinary tract infection. There is a wide range of conditions that result in acute renal inflammation and those under discussion affect primarily the interstitium. This term refers to the connective tissue elements separating the tubules in the cortex and medulla. Hence, the interstitial nephritides are to be distinguished from the glomerulonephritides and fall into two general etiologic categories: infectious and noninfectious

Reduced activity of 11beta-hydroxysteroid dehydrogenase type 2 is not responsible for sodium retention in nephrotic rats

AIM: In mineralocorticoid target cells 11-beta-hydroxysteroid dehydrogenase type 2 (11betaHSD2) converts glucocorticoids into non-active metabolites thereby protecting the mineralocorticoid receptor (MR) from stimulation by glucocorticoids. In nephrotic syndrome, a decreased activity of 11betaHSD2...... has been suggested to allow glucocorticoids to stimulate MR, thereby contributing to sodium retention. We tested this hypothesis in the puromycin aminonucleoside model of nephrotic syndrome in rats. METHODS: Complete sodium and potassium intakes and excretions (faeces and urine) were measured in rats......)] to suppress endogenous glucocorticoids in the proteinuric stage during active sodium retention. RESULTS: Nephrotic rats developed proteinuria, positive sodium balance, decreased plasma aldosterone concentration, and decreased urinary Na(+)/K(+) ratio. 11betaHSD2 mRNA expression was down-regulated but protein...

Urinary tract infections in infants and children: Diagnosis and management.

Recent studies have resulted in major changes in the management of urinary tract infections (UTIs) in children. The present statement focuses on the diagnosis and management of infants and children >2 months of age with an acute UTI and no known underlying urinary tract pathology or risk factors for a neurogenic bladder. UTI should be ruled out in preverbal children with unexplained fever and in older children with symptoms suggestive of UTI (dysuria, urinary frequency, hematuria, abdominal pain, back pain or new daytime incontinence). A midstream urine sample should be collected for urinalysis and culture in toilet-trained children; others should have urine collected by catheter or by suprapubic aspirate. UTI is unlikely if the urinalysis is completely normal. A bagged urine sample may be used for urinalysis but should not be used for urine culture. Antibiotic treatment for seven to 10 days is recommended for febrile UTI. Oral antibiotics may be offered as initial treatment when the child is not seriously ill and is likely to receive and tolerate every dose. Children UTI with a renal/bladder ultrasound to identify any significant renal abnormalities. A voiding cystourethrogram is not required for children with a first UTI unless the renal/bladder ultrasound reveals findings suggestive of vesicoureteral reflux, selected renal anomalies or obstructive uropathy.

Progressive interstitial fibrosis and tubular atrophy (IF/TA) is a leading cause of chronic allograft dysfunction. Increased extracellular matrix remodeling regulated by matrix metalloproteases (MMPs) and their inhibitors (TIMPs) has been implicated in the development of IF/TA. The aim of this study was to investigate whether urinary/serum MMPs/TIMPs correlate with subclinical IF/TA detected in surveillance biopsies within the first 6months post-transplant. We measured eight different MMPs/TIMPs simultaneously in urine and serum samples from patients classified as normal histology (n=15), IF/TA 1 (n=15) and IF/TA 2-3 (n=10). There was no difference in urinary MMPs/TIMPs among the three groups, and only 1/8 serum MMPs/TIMPs (i.e. MMP-1) was significantly elevated in biopsies with IF/TA 2-3 (p=0.01). In addition, urinary/serum MMPs/TIMPs were not different between surveillance biopsies demonstrating an early development of IF/TA (i.e. delta IF/TA≥1 compared to a previous biopsy obtained three months before; n=11) and stable grade of IF/TA (i.e. delta IF/TA=0; n=20). Next, we investigated whether urinary/serum MMP/TIMP levels are elevated during acute subclinical tubulitis in surveillance biopsies obtained within the first 6months post-transplant (n=25). Compared to biopsies with normal histology, serum MMPs/TIMPs were not different; however, all urinary MMP/TIMP levels were numerically higher during subclinical tubulitis (MMP-1, MMP-7, TIMP-1 with p≤0.04). We conclude that urinary/serum MMPs/TIMPs do hardly correlate with existing or early developing IF/TA in surveillance biopsies obtained within the first 6months post-transplant. This could be explained by the dynamic process of extracellular matrix remodeling, which seems to be active during acute tubulo-interstitial injury/inflammation, but not in quiescent IF/TA.

Full Text Available This report presents an alternative method for the retention of partial dentures that relies on the engagement of tooth undercuts by a lining material. The lab procedures are also presented. A new maxillary and mandibular acrylic partial dentures were fabricated using elastomeric retention technique for a partially dentate patient. A partially dentate man reported difficulty in retaining his upper removable partial denture (RPD. The maxillary RPD was designed utilizing elastomeric retention technique. During follow-up, it was necessary to replace the retention rings due to wear. The replacement of the retention rings, in this case, was done through a chairside reline technique. Elastomeric retention technique provides exceptionally good retention can be indicated to stabilize, cushion, splint periodontally involved teeth, no enough undercut for clasps, eliminate extractions, single or isolated teeth.

Urethral obstruction from dislodged bladder Diverticulum stones: a case report

Directory of Open Access Journals (Sweden)

Okeke Linus I

2012-11-01

Full Text Available Abstract Background Secondary urethral stone although rare, commonly arises from the kidneys, bladder or are seen in patients with urethral stricture. These stones are either found in the posterior or anterior urethra and do result in acute urinary retention. We report urethral obstruction from dislodged bladder diverticulum stones. This to our knowledge is the first report from Nigeria and in English literature. Case presentation A 69 year old, male, Nigerian with clinical and radiological features of acute urinary retention, benign prostate enlargement and bladder diverticulum. He had a transurethral resection of the prostate (TURP and was lost to follow up. He re-presented with retained urethral catheter of 4months duration. The catheter was removed but attempt at re-passing the catheter failed and a suprapubic cystostomy was performed. Clinical examination and plain radiograph of the penis confirmed anterior and posterior urethral stones. He had meatotomy and antegrade manual stone extraction with no urethra injury. Conclusions Urethral obstruction can result from inadequate treatment of patient with benign prostate enlargement and bladder diverticulum stones. Surgeons in resource limited environment should be conversant with transurethral resection of the prostate and cystolithotripsy or open prostatectomy and diverticulectomy.

Acute Poisoning with Methadone (Dolphin (Review

Directory of Open Access Journals (Sweden)

Georgy A. Livanov

2017-01-01

Full Text Available Most publications report on the use of methadone as a medication, however an increase of the illegal use of methadone has been demonstrated worldwide over the recent years, thus increasing the number of hospitalizations due to acute poisoning with this synthetic opioid. The aim of the present review was to summarize current data on the mechanisms of toxicity, selective toxicity, toxicokinetics and toxicodynamics of methadone (Dolphin. The involvement of CNS, respiratory, cardiovascular and urinary systems in acute poisoning with methadone was dis- cussed. The practice of use of methadone in many countries as a medicine for the replacement therapy for opiate addicts was analyzed. In addition, it was suggested that the results of the use of naloxone antidote therapy in acute opioid poisoning do not always clearly demonstrate its sufficient efficacy. Ways to improve of the intensive therapy of severe acute poisoning by methadone were substantiated; in addition to general critical care methods, treatment with a complex metabolic antihypoxant cytoflavin should be considered.

Lee, Seung Joo; Cha, Jihae; Lee, Jung Won

2016-11-01

Pyelonephritis in infants is considered as a major factor for the formation of renal scar. To prevent recurrent pyelonephritis and renal damage, prophylaxis is extremely important. The aim of this study was to compare the effectiveness of probiotic and antibiotic prophylaxis or no-prophylaxis in infants with pyelonephritis and normal urinary tract. Altogether 191 infants, who were diagnosed with acute pyelonephritis, proven to have normal urinary tracts and followed up for 6 months on prophylaxis, were retrospectively evaluated. According to the types of prophylaxis, the infants were divided into three groups [probiotics (Lactobacillus species), antibiotics (trimethoprim/sulfamethoxazole, TMP/SMX), and noprophylaxis]. The incidence of recurrent urinary tract infection (UTI) during 6 months after the development of pyelonephritis, main causative uropathogens, and its antimicrobial sensitivities were compared. The incidence of recurrent UTI in the probiotic group was 8.2%, which was significantly lower than 20.6% in the no-prophylaxis group (P=0.035) and was not significantly different from 10.0% of the antibiotic group (P=0.532). The significant difference between the probiotic and no-prophylaxis groups was seen only in male infants (P=0.032). The main causative organism of recurrent UTI was Escherichia coli (E.coli), which was not different among the three groups (P=0.305). The resistance rate of E. coli to TMP/SMX was 100% in the antibiotic group, which was significantly higher than 25.0% in the probiotic group and 41.7% in the no-prophylaxis group (P=0.008). Probiotic prophylaxis was more effective in infants with pyelonephritis and normal urinary tract than in those with no-prophylaxis. It could be used as a natural alternative to antibiotic prophylaxis.

The evolution of rectal and urinary toxicity and immune response in prostate cancer patients treated with two three-dimensional conformal radiotherapy techniques

International Nuclear Information System (INIS)

Vranova, Jana; Vinakurau, Stepan; Richter, Jan; Starec, Miroslav; Fiserova, Anna; Rosina, Jozef

2011-01-01

Our research compared whole pelvic (WP) and prostate-only (PO) 3-dimensional conformal radiotherapy (3DCRT) techniques in terms of the incidence and evolution of acute and late toxicity of the rectum and urinary bladder, and identified the PTV-parameters influencing these damages and changes in antitumor immune response. We analyzed 197 prostate cancer patients undergoing 3DCRT for gastrointestinal (GI) and genitourinary (GU) toxicities, and conducted a pilot immunological study including flow cytometry and an NK cell cytotoxicity assay. Acute and late toxicities were recorded according to the RTOG and the LENT-SOMA scales, respectively. Univariate and multivariate analyses were conducted for factors associated with toxicity. In the WP group, an increase of acute rectal toxicity was observed. A higher incidence of late GI/GU toxicity appeared in the PO group. Only 18 patients (WP-7.76% and PO-11.11%) suffered severe late GI toxicity, and 26 patients (WP-11.21% and PO-16.05%) severe late GU toxicity. In the majority of acute toxicity suffering patients, the diminution of late GI/GU toxicity to grade 1 or to no toxicity after radiotherapy was observed. The 3DCRT technique itself, patient age, T stage of TNM classification, surgical intervention, and some dose-volume parameters emerged as important factors in the probability of developing acute and late GI/GU toxicity. The proportion and differentiation of NK cells positively correlated during 3DCRT and negatively so after its completion with dose-volumes of the rectum and urinary bladder. T and NKT cells were down-regulated throughout the whole period. We found a negative correlation between leukocyte numbers and bone marrow irradiated by 44-54 Gy and a positive one for NK cell proportion and doses of 5-25 Gy. The acute GU, late GU, and GI toxicities up-regulated the T cell (CTL) numbers and NK cytotoxicity. Our study demonstrates the association of acute and late damage of the urinary bladder and rectum, with

Detrusor Acontractility after Acute Spinal Cord Injury-Myth or Reality?

Science.gov (United States)

Bywater, Mirjam; Tornic, Jure; Mehnert, Ulrich; Kessler, Thomas M

2018-01-17

We assessed urodynamic parameters within the first 40 days after spinal cord injury to investigate whether the detrusor is acontractile during the acute phase of spinal cord injury. We performed a prospective cohort study in 54 patients with neurogenic lower urinary tract dysfunction due to acute spinal cord injury who underwent urodynamic investigation within the first 40 days after injury at a single university spinal cord injury center. Urodynamic investigation revealed an acontractile detrusor in only 20 of the 54 patients (37%) but unfavorable urodynamic parameters in 34 (63%). We found detrusor overactivity in 32 patients, detrusor-sphincter dyssynergia in 25, maximum storage detrusor pressure greater than 40 cm H 2 O in 17, vesicoureteral reflux in 3 and low bladder compliance (less than 20 ml/cm H 2 O) in 1. More than 1 unfavorable urodynamic parameter per patient was possible. In contrast to the common notion of an acontractile detrusor during acute spinal cord injury, almost two-thirds of our patients showed unfavorable urodynamic parameters within the first 40 days after spinal cord injury. Considering that early treatment of neurogenic lower urinary tract dysfunction in patients with acute spinal cord injury might improve the long-term urological outcome, urodynamic investigation should be performed timely to optimize patient tailored therapy.

Secondary complications of spinal cord injury (SCI) are a burden to affected individuals and the rest of society. There is limited evidence of the economic burden or cost of complications in SCI populations in Canada, however, which is necessary for comparative economic analyses and decision analytic modeling of possible solutions to these common health problems. Comparative economic analyses can inform resource allocation decisions, but the outputs are only as good as the inputs. In this article, new evidence of the excess or incremental costs of urinary tract infection (UTI) and pressure ulceration (PU) in acute traumatic SCI from an exploratory case series analysis of admissions to a Level I specialized Canadian spine facility (2008-2013) is presented. Participants in a national SCI registry were case-control matched (1:1) on the predicted probability of experiencing UTI or PU during initial acute SCI admission. The excess costs of UTI and PU are estimated as the mean of the differences in total direct acute SCI admission costs (length of stay, accommodation, nursing, pharmacy) from the perspective of the admitting facility between participants matched or paired on demographic and SCI characteristics. Even relatively minor UTI and PU, respectively, added an average of $7,790 (standard deviation [SD] $6,267) and $18,758 (SD $27,574) to the direct cost of acute SCI admission in 2013 Canadian dollars (CAD). This case series analysis established evidence of the excess costs of UTI and PU in acute SCI admissions, which will support decision-informing analyses in SCI.

Preexisting renal impairment and the amount of contrast media are the most important risk factors for contrast-induced acute kidney injury (CI-AKI). We aimed to investigate whether the product of contrast medium volume and urinary albumin/creatinine ratio (CMV × UACR) would be a better predictor of CI-AKI in patients undergoing nonemergency coronary interventions. This was a prospective single-center observational study, and 912 consecutive patients who were exposed to contrast media during coronary interventions were investigated prospectively. CI-AKI is defined as a 44.2 μmol/L rise in serum creatinine or a 25% increase, assessed within 48 h after administration of contrast media in the absence of other causes. Fifty patients (5.48%) developed CI-AKI. The urinary albumin/creatinine ratio (UACR) (OR = 1.002, 95% CI = 1.000-1.003, p = .012) and contrast medium volume (CMV) (OR = 1.008, 95% CI = 1.001-1.014, p = .017) were independent risk factors for the development of CI-AKI. The area under the ROC curve of CMV, UACR and CMV × UACR were 0.662 (95% CI = 0.584-0.741, p < .001), 0.761 (95% CI = 0.674-0.847, p < .001) and 0.808 (95% CI = 0.747-0.896, p < .001), respectively. The cutoff value of CMV × UACR to predict CI-AKI was 1186.2, with 80.0% sensitivity and 62.2% specificity. The product of CMV and UACR (CMV × UACR) might be a predictor of CI-AKI in patients undergoing nonemergency coronary interventions, which was superior to CMV or UACR alone.

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

Objective: To calculate the frequencies of acute pyelonephritis and renal scarring in patients under the age of two, with first episode of urinary tract infection in a Brazilian university hospital, comparing with data reported in the international literature. Materials and Methods: Scintigraphic reports of children less than two years old submitted to {sup 99m}Tc-DMSA renal scintigraphy in a university hospital in Rio Grande do Sul between 2006 and 2009 were reviewed to investigate acute pyelonephritis/renal scarring. Additionally, the presence of vesicoureteral reflux, early use of antibiotics, and comorbidities were investigated on electronic records. The sample size calculation was based on a systematic review study and obtained a minimum of 147 patients. Patients whose electronic records were not available were excluded. Results: One hundred and fifty-seven children met the inclusion criteria; among them 48 had acute pyelonephritis and 8 of these had renal scars. Neither age nor sex presented any significant association with acute pyelonephritis (p = 0.405 and p = 0.124, respectively). No statistical significance was observed in the association between vesicoureteral reflux and acute pyelonephritis (p = 1.0) and other comorbidities (p = 0.470), and in relation to early use of antibiotics with acute pyelonephritis (p = 0.130) and renal scarring (p = 0.720). Conclusion: The frequencies found in the present study for acute pyelonephritis/renal scarring are in agreement with the results reported by most studies in the literature. (author)

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

Behall, Kay M; Howe, Juliette C; Anderson, Richard A

2002-07-01

The effects on apparent mineral retention after long-term consumption of a high amylose diet containing 30 g resistant starch (RS) were investigated in 10 control and 14 hyperinsulinemic men. Subjects consumed products (bread, muffins, cookies, corn flakes and cheese puffs) made with standard (70% amylopectin, 30% amylose; AP) or high amylose (70% amylose, 30% amylopectin; AM) cornstarch for two 14-wk periods in a crossover pattern. Starch products replaced usual starches in the habitual diet for 10 wk followed by 4 wk of consuming the controlled diets. During wk 12, all urine, feces and duplicate foods were collected for 7 d. Urinary chromium losses after a glucose tolerance test or 24-h collections of the hyperinsulinemic and control subjects did not differ and were not altered by diet. Except for zinc, the two subject types did not differ significantly in apparent mineral balance. Apparent retentions of calcium and magnesium were not significantly affected by diet (AM vs. AP) or type-by-diet interaction. Apparent iron retention tended to be greater after AM than AP consumption (P copper retention was greater after consuming AP than after AM (P < 0.02), whereas apparent zinc retention was greater after consuming AM than after AP (P < 0.018). Zinc also showed a significant type-by-diet interaction (P < 0.034) with control subjects retaining less zinc after consuming AP than after AM. In summary, a high amylose cornstarch diet containing 30 g RS could be consumed long term without markedly affecting, and possibly enhancing, retention of some minerals.

Therapies in early development for the treatment of urinary tract inflammation.

Science.gov (United States)

Zacchè, Martino Maria; Giarenis, Ilias

2016-01-01

Urinary tract inflammation is a very common clinical condition. It is caused by several pathogens and antibiotic treatment is the mainstay of therapy. Increasing antimicrobial resistance and high recurrence rates represent a challenge. Consequently, there is an unmet need for new therapeutic options. The authors discuss the rationale of emerging management strategies and current experimentation. Furthermore, they focus on both acute and recurrent urinary tract infections (UTIs) and examine a range of therapeutics, including new antibiotics, vaccines, mannosides, hyaluronic acid, probiotics, immunomodulant agents and novel compounds derived from nanotechnology. Basic science studies have elucidated the pathogenesis of UTIs and built up the ground for the development of new therapies. Evidence is mainly derived from animal studies on murine models of bacterial cystitis. However, clinical trials are scanty and cannot provide us with robust evidence. Hetereogeneity and virulence of uropathogens pose a threat that scientists and clinicians are struggling to overcome.

An update on new antibiotic prophylaxis and treatment for urinary tract infections in children.

Science.gov (United States)

Delbet, Jean Daniel; Lorrot, Mathie; Ulinski, Tim

2017-10-01

This review focuses on the treatment of urinary tract infections (UTI) in children and in particular its recent changes. Areas covered: Acute pyelonephritis, acute cystitis and asymptomatic bacteriuria or asymptomatic infections have to be clearly distinguished. Prompt treatment is required in pyelonephritis and cystitis, but not in asymptomatic bacteriuria or infection, in order to avoid selection of more virulent strains. This concept should be considered even in immunocompromised or bedridden children. In case of pyelonephritis, there should be no delay in beginning the antibiotic treatment in order to decrease the risk of long term complication, such as renal scars. Predisposing conditions for UTI, such as voiding anomalies and urinary tract malformation should be carefully evaluated. Expert opinion: One major concern is the increasing resistance to 3 rd generation cephalosporins. Therefore overconsumption in low-risk settings should be absolutely avoided. The prevalence of infections with E. coli producing extended spectrum ß-lactamase (ESBL) is increasing and pediatricians should be aware about the specific treatment options. Any recommendation about (initial) antibiotic treatment should be regularly updated and adapted to local resistance profiles and to economic factors in different health systems.

Urinary arsenic speciation profiles in mice subchronically exposed to low concentrations of sodium arsenate in drinking water

Directory of Open Access Journals (Sweden)

Huijie Wu

2011-09-01

Full Text Available Arsenic is a proven human carcinogen. Although the mechanism of its carcinogenicity is still largely unknown, methylation is thought to have an important role to play in arsenic toxicity. In this study, urinary methylation profiles were investigated in female C57BL/6J black mice given drinking water containing 500 μg arsenate (AsV/L, 250 μg AsV/L, or 100 μg AsV/L as sodium arsenate for 2 months. The concentrations of arsenic chosen reflected those in the drinking water often encountered in arsenic-endemic areas. Urine samples were collected from the mice at the end of the exposure period, and the arsenic species were analyzed by high performance liquid chromatography-inductively coupled plasma-mass spectrometry. All detectable arsenic species showed strong linear correlation with the administered dosage. The methylation patterns were similar in all three groups with a slight decrease of dimethylarsinic acid/AsV ratio in the 500-μg/L group, which corresponded to the significantly higher arsenic retention in the tissue. The results indicate that urinary arsenic could be used as a good biomarker for internal dose and potential biological effects. Different doses of arsenic exposure could result in different degrees of methylation, excretion, and tissue retention, and this may contribute to the understanding of arsenic carcinogenicity.

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

Bilateral chronic sacral neuromodulation for treatment of lower urinary tract dysfunction.

Science.gov (United States)

Hohenfellner, M; Schultz-Lampel, D; Dahms, S; Matzel, K; Thüroff, J W

1998-09-01

Chronic sacral neuromodulation aims at functional restoration of selected forms of nonneurogenic and neurogenic bladder dysfunction. The original technique, as described by Tanagho and Schmidt, provides unilateral sacral nerve stimulation via an implanted stimulator powering an electrode inserted into a sacral foramen. Its drawback was that the implant failed unpredictably in some patients despite previous successful percutaneous test stimulation. Therefore, we modified the stimulation technique to improve the efficacy of chronic sacral neuromodulation. Guarded bipolar electrodes powered by an implantable neurostimulator were attached bilaterally directly to the S3 nerves through a sacral laminectomy in 9 women and 2 men (mean age 43.4 years). Of the patients 5 had urinary incontinence due to detrusor hyperactivity and 6 had urinary retention from detrusor hypocontractility. Mean followup with repeated urodynamics was 13 months (range 9 to 28). Four significant complications were encountered in 4 patients. In 10 patients the urological sequelae of the neurological disorder were alleviated significantly (50% or more), including 5 who experienced complete relief of symptoms. The efficacy of chronic sacral neuromodulation can be improved by bilateral attachment of electrodes directly to the sacral nerves.

Is ciprofloxacin safe in patients with solitary kidney and upper urinary tract infection?

The solitary kidney (SK) undergoes adaptive phenomena of hyperfunction and hyperfiltration. These secondary adaptive phenomena can make it more vulnerable to potentially nephrotoxic therapies. Adverse reactions of the kidneys to ciprofloxacin are rare, but sometimes severe. Therefore, our study sought to assess the reactions to ciprofloxacin of patients with solitary kidney (SK) and urinary tract infection (UTI) by means of urinary biomarkers. We studied 19 patients with SK and urinary tract infection (UTI) who had been administered a 7-day treatment with intravenous ciprofloxacin. Urinary N-acetyl-beta-d-glucosaminidase, alpha 1-microglobulin, and estimated glomerular filtration rate (eGFR) of these patients were measured at the initiation and at the end of treatment. In 47.37% patients NAG diminished under ciprofloxacin treatment. This observation has the significance of favourable evolution of the tubulointerstitial lesions caused by UTI and lack of nephrotoxic effects; 52.63% cases presented an increase of urinary NAG, a fact that suggests a nephrotoxic effect of ciprofloxacin. The evolution of urinary alpha 1-microglobulin was similar to that one of urinary NAG. Only one of three cases with chronic kidney disease (CKD) stage 5 presented acute kidney injury, associated with increase in the tubular markers. In spite of the high variability of the urinary biomarkers, UTI evolved favourably in these cases; eGFR increased in 16 out of 19 patients, a fact which is indicative of a good outcome of renal function, even in patients with elevated levels of the tubular damage biomarkers. This observation supports the hypothesis that eGFR may be dissociated from the biomarkers which assess tubular injury. In SK patients the occurrence of AKI is not frequent, although the urinary biomarkers rise in some patients treated with ciprofloxacin. This is related not only to the nephrotoxic effect of the drug, but probably to the association of other factors (allergy, individual

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

2007-01-01

Background and purpose: To analyze the impact of Tomotherapy (TOMO) intensity modulated radiotherapy (IMRT) on acute gastrointestinal (GI) and genitourinary (GU) toxicity in prostate cancer. Materials and methods: The records of 55 consecutively treated TOMO patients were reviewed. Additionally a well-matched group of 43 patients treated with LINAC-based step and shoot IMRT (LINAC) was identified. Acute toxicity was scored according to Radiation Therapy Oncology Group acute toxicity criterion. Results: The grade 2-3 acute GU toxicity rates for the TOMO vs. LINAC groups were 51% vs. 28% (p = 0.001). Acute grade 2 GI toxicity was 25% vs. 40% (p = 0.024), with no grade 3 GI toxicity in either group. In univariate analysis, androgen deprivation, prostate volume, pre-treatment urinary toxicity, and prostate dose homogeneity correlated with acute GI and GU toxicity. With multivariate analysis use of Tomotherapy, median bladder dose and bladder dose homogeneity remained significantly correlated with GU toxicity. Conclusions: Acute GI toxicity for prostate cancer is improved with Tomotherapy at a cost of increased acute GU toxicity possibly due to differences in bladder and prostate dose distribution

Full Text Available Preliminary evidence suggests a nephroprotective effect of urinary alkalinization in patients at risk of acute kidney injury. In this study, we tested whether prophylactic bicarbonate-based infusion reduces the incidence of acute kidney injury and tubular damage in patients undergoing open heart surgery.In a multicenter, double-blinded (patients, clinical and research personnel, randomized controlled trial we enrolled 350 adult patients undergoing open heart surgery with the use of cardiopulmonary bypass. At induction of anesthesia, patients received either 24 hours of intravenous infusion of sodium bicarbonate (5.1 mmol/kg or sodium chloride (5.1 mmol/kg. The primary endpoint was the proportion of patients developing acute kidney injury. Secondary endpoints included the magnitude of acute tubular damage as measured by urinary neutrophil gelatinase-associated lipocalin (NGAL, initiation of acute renal replacement therapy, and mortality. The study was stopped early under recommendation of the Data Safety and Monitoring Committee because interim analysis suggested likely lack of efficacy and possible harm. Groups were non-significantly different at baseline except that a greater proportion of patients in the sodium bicarbonate group (66/174 [38%] presented with preoperative chronic kidney disease compared to control (44/176 [25%]; p = 0.009. Sodium bicarbonate increased urinary pH (from 6.0 to 7.5, p<0.001. More patients receiving bicarbonate (83/174 [47.7%] developed acute kidney injury compared with control patients (64/176 [36.4%], odds ratio [OR] 1.60 [95% CI 1.04-2.45]; unadjusted p = 0.032. After multivariable adjustment, a non-significant unfavorable group difference affecting patients receiving sodium bicarbonate was found for the primary endpoint (OR 1.45 [0.90-2.33], p = 0.120]. A greater postoperative increase in urinary NGAL in patients receiving bicarbonate infusion was observed compared to control patients (p = 0

Indoleamine-2,3-dioxygenase (IDO) catalyzes the first step of tryptophan (Trp) catabolism, yielding kynurenine (Kyn) metabolites. The kynurenine-to-tryptophan (K/T) ratio is used as a surrogate for biological IDO enzyme activity. IDO expression is increased during Escherichia coli urinary tract infection (UTI). Thus, our objective was to develop a method for measurement of Kyn/Trp ratio in human blood and urine and evaluate its use as a biomarker of UTI. A mass spectrometric method was developed to measure Trp and Kyn in serum and urine specimens. The method was applied to clinical urine specimens from symptomatic pediatric patients with laboratory-confirmed UTI or other acute conditions and from healthy controls. The liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was linear to 500 μmol/L for both Trp and Kyn. Imprecision ranged from 5 to 15% for Trp and 6-20% for Kyn. Analytical recoveries of Trp and Kyn ranged from 96 to 119% in serum and 90-97% in urine. No correlation was found between the K/T ratio and circulating IDO mass (r = 0.110) in serum. Urinary Kyn and Trp in the pediatric test cohort demonstrated elevations in the K/T ratio in symptomatic patients with UTI (median 13.08) and without UTI (median 14.38) compared to healthy controls (median 4.93; p < 0.001 for both comparisons). No significant difference in K/T ratio was noted between symptomatic patients with and without UTI (p = 0.84). Measurement of Trp and Kyn by LC-MS/MS is accurate and precise in serum and urine specimens. While urinary K/T ratio is not a specific biomarker for UTI, it may represent a general indicator of a systemic inflammatory process. Copyright © 2018 The Canadian Society of Clinical Chemists.

Purpose: Acute pyelonephritis is a major cause of morbidity in children with urinary tract infection and can result in irreversible renal scarring leading to hypertension and end-stage renal disease. Tc-99m-dimercaptosuccinic acid (DMSA) scintigraphy is the imaging modality of choice for the detection of acute pyelonephhfis and renal scarfing. This study evaluated the importance of renal cortical scintigraphy to identify children at risk from renal damage due to acute pyelonephritis. Methods: Forty-nine children (ages 9 months to 11 years) with urinary tract infection having positive urine culture were studied. A DMSA scan was performed within 72 hours of receiving antibiotic during acute infection. Single or multiple areas of varying degrees of diminished cortical uptake or diffusely decreased uptake in an enlarged kidney was considered for the diagnosis of acute pyelonephrifis. Follow-up scintigraphy was done at 6 months of initial scan in children with acute pyelonephritis documented by DMSA scan. Renal scarring was considered if the affected kidney shows cortical thinning or focal cortical defect with loss of volume or become small kidney. Children with known renal tract abnormalities were excluded from the study. RESULTS: Twenty-seven children (55%) wine considered acute pyelonephritis by DMSA scintigraphy and the abnormality was bilateral in 17(63%) cases and unilateral in 10(37%) cases. Among these 44 abnormal kidneys, scintigraphy showed solitary defect in 29 kidneys, multiple defects in 6 kidneys and diffuse decreased uptake in 9 kidneys. Of them, twenty children were available for follow-up evaluation and scintigraphy demonstrated complete recovery in 21 of 34 (62%) kidneys and renal scarfing in 13 of 34 (38%) kidneys. Renal scarring was found in 5 of 7 kidneys (71%) with diffuse decreased uptake, 2 of 5 kidneys (40%) with multiple cortical defect and 6 of 22 (27%) with single focal detect. Conclusion: The scintigraphic pattern of acute pyelonephritis

Full Text Available Decrease of urinary phosphate (P excretion and P retention triggers activation of phosphotonins and subsequent development of secondary hyperparathyroidism in progressing of chronic kidney disease (CKD. The main source of P is dietary protein. No large studies are presented to-date to evaluate the relationship between dietary protein intake and parameters of P metabolism in CKD patients. This was a goal of the cross-sectional cohort study .11315 CKD patients were entered (males 43%. Median (10th-90th percentile of age and estimated glomerular filtration rate (GFR were 46 (24-69 and 64 (24-104. The analyzed data were: age, gender, body mass index (BMI serum albumin, creatinine, calcium and phosphate; 24-h urine creatinine, phosphate (P,proteinuria (DP. Estimated parameters includes: eGFR, fractional P excretion (FEP, 24-h P excretion (24-h UP, and P clearance (CP. Dietary protein intake (DPI was based on 24-h urinary urea excretion. No significant differences in serum phosphate were found in groups with various DPI. FEP, 24-h UP and CP were significantly higher in higher DPI range. DPI was positively associated with 24-h UP (β=0,287, p<0.000001 in multivariate model adjusted for age, gender, DP, eGFR, serum P, FEP, BMI, and Ca. Thus, DPI is considered to be the independent factor influencing urinary P excretion and hence contributing to progression of mineral and bone disease in renal dysfunction.

Full Text Available Objective: The present study aimed to determine whether castration altered osmotically stimulated vasopressin (VP release and urinary volume and what is the role of endocrine-stress axis in this process.Materials and methods: Totally 108 mice were studied in two main groups of castrated (n=78 and control (n=30. Each group was extracted by acute cold stress (4◦C for 2h/day, restraint stress (by syringes 60cc 2h/day and cold/restraint stress. The castrated group was treated in sub groups of testosterone, control (sesame oil as vehicle of testosterone. Propranolol as blocker of sympathetic nervous system was given to both groups of castrated mice and main control.Results: Our results showed that, there is interactions between testosterone and sympathetic nervous system on vasopressin, because urine volume was decreased only in testoctomized mice with cold/restraint and cold stress (P<0.001; propranolol as the antagonist of sympathetic nervous system could block and increase urine volume in castrated mice. This increased volume of urine was due to acute cold stress, not restraint stress (p<0.001. The role of testosterone, noradrenalin (NA and Vasopressin (VP in the acute cold stress is confirmed, because testosterone could return the effect of decreased urine volume in control group (P<0.001. Conclusion: Considering the effect of cold/restraint stress on urinary volume in castrated mice shows that there is interaction between sex hormone (testosterone, vasopressin and adrenergic systems.

URINARY CREATINE AT REST AND AFTER REPEATED SPRINTS IN ATHLETES: A PILOT STUDY

Full Text Available Creatine plays a key role in muscle function and its evaluation is important in athletes. In this study, urinary creatine concentration was measured in order to highlight its possible significance in monitoring sprinters. The study included 51 sprinters and 25 age- and sex-matched untrained subjects as a control group. Body composition was measured and dietary intake estimated. Urine samples were collected before and after standardized physical exercise. Creatine was assessed by gas chromatography mass spectrometry. Basal urinary creatine (UC was significantly lower in sprinters than controls (34±30 vs. 74±3 μmol/mmol creatinine, p<0.05. UC was inversely correlated with body mass (r=-0.34, p<0.01 and lean mass (r=- 0.30, p<0.05, and positively correlated with fat mass (r=0.32, p<0.05. After acute exercise, urinary creatine significantly decreased in both athletes and controls. UC is low in sprinters at rest and further decreases after exercise, most likely due to a high uptake and use of creatine by muscles, as muscle mass and physical activity are supposed to be greater in athletes than untrained subjects. Further studies are needed to test the value of urinary creatine as a non-invasive marker of physical condition and as a parameter for managing Cr supplementation in athletes.

Background Plasma nitrite serves as a reservoir of nitric oxide (NO) bioactivity. Because nitrite ingestion is markedly lower in newborns than adults, we hypothesized plasma nitrite levels would be lower in newborns than in adults, and that infants diagnosed with necrotizing enterocolitis (NEC), a disease characterized by ischemia and bacterial invasion of intestinal walls, would have lower levels of circulating nitrite in the days prior to diagnosis. Methods Single blood and urine samples were collected from 9 term infants and 12 adults, 72 preterm infants every 5 d for 3 wk, and from 13 lambs before and after cord occlusion. Results Nitrite fell 50% relative to cord levels in the first day after birth; and within 15 min after cord occlusion in lambs. Urinary nitrite was higher in infants than adults. Plasma and urinary nitrite levels in infants who developed NEC were similar to those of preterm control infants on days 1 and 5, but significantly elevated at 15 and 20 d after birth. Conclusion Plasma nitrite falls dramatically at birth while newborn urinary nitrite levels are significantly greater than adults. Acute NEC is associated with elevated plasma and urinary nitrite levels. PMID:26539663

The increasing resistance of uropathogens to antibiotics and recognition of the generally self-limiting nature of uncomplicated urinary tract infection (UTI) suggest that it is time to reconsider empirical treatment of UTI using antibiotics. Identifying new and effective strategies to prevent recurrences and alternative treatment strategies are a high priority. We review the recent literature regarding the effects of functional food products, probiotics, vaccines, and alternative treatments on treating and preventing UTI.

2002-01-01

Purpose: To evaluate the relationship between acute and late normal tissue reactions in 317 consecutive endometrial cancer patients treated with surgery and adjuvant radiotherapy (RT). Methods: The data of 317 patients (staging according to the International Federation of Gynecology and Obstetrics) treated with postoperative RT were analyzed. Both low-dose-rate brachytherapy and external beam RT were applied in 247 patients (78%); brachytherapy only in 49 (15%) and external beam irradiation only in 21 (7%). The median follow-up was 7.3 years (range 4-21). The European Organization for Research and Treatment of Cancer, Radiation Therapy Oncology Group system with elements of the late effects of normal tissue, subjective, objective, management, analytic (LENT/SOMA) scale was used to score the RT reactions. The correlation between the occurrence and severity of acute and late bowel and bladder toxicity, as well as the relationship between the severity of acute effects and time to occurrence of late reactions, were assessed using linear and logistic regression analyses. Results: Of the 317 patients, 268 (85%) experienced acute RT reactions of any grade. Severe acute bowel reactions were observed in 15 patients (5%), urinary bladder complications in 1 patient (0.5%), cutaneous in 1 patient (0.5%), and vaginal in 1 patient (0.5%). Severe acute hematologic toxicity was seen in 3 patients (1%). A total of 158 patients (51%) experienced late RT reactions of any grade. Severe late bowel reactions were observed in 19 patients (6%), urinary bladder in 5 (2%), vaginal in 3 (1%), and bone in 10 (4%). When all toxic events were considered, there was a highly significant correlation between the acute and late bowel reactions (p <0.001), but the acute and late urinary bladder reactions did not correlate (p=0.64). The grade of acute toxicity was found to predict the grade of late toxicity for the bowel but not for the bladder (p<0.001 and p=0.47, respectively). The severity of acute

Urinary tract infection in children is well recognized as a cause of acute morbidity and chronic medical conditions. As a result, appropriate use of antimicrobial agents, however, increases antibiotic resistance and complicates its treatment due to increased patient morbidity, costs, rates of hospitalization, and use of broader-spectrum antibiotics. The goal of this study was to determine antibiotic susceptibility to commonly used agents for urinary tract infection against recent urinary isolates. A total of 457 consecutive children attending the emergency room at the Hospital Infantil de México Federico Gómez with symptoms of uncomplicated lower urinary tract infection were eligible for inclusion. Patients who had had symptoms for≥7 days and those who had had previous episodes of urinary tract infection, received antibiotics or other complicated factors were excluded. Midstream and catheter urine specimens were collected. All isolates were identified and the in vitro activities of antimicrobials were determined. The most frequently isolated urinary pathogens were as follows: Escherichia coli (E. coli) (312, 68.3%), Enterococcus spp. (42, 11%), Klebsiella pneumoniae (K. pneumoniae) (40, 8.7%), Pseudomonas aeruginosa (P. aeruginosa) (34, 7.5%), Proteus mirabilis (P. mirabilis) (21, 4.5%), Enterobacter cloacae (8, 1.7%). The resistance to trimetoprim/sulfametoxazol (%) was 73.7, 62.2, 100, 52, and 50, respectively, for E. coli, K. pneumoniae, P. aeruginosa, P. mirabilis and Enterobacter spp., 92.5 for Enterococcus faecalis (E. faecalis) and 49.9 for Enterococcus faecium (E. faecium). Ampicillin was 86.3, 45, 100, 47.9, and 66.6% for the same strains, ciprofloxacin 33.8, 9, 18.8, 0, 0%, nitrofurantoin 4.4, 13, 97.7, 70, 0%; to E. faecalis 0% and 16.7% to E. faecium.

Franceschini, A; Duthel, J M; Vallon, J J

1991-03-22

A specific, sensitive and reliable gas chromatography-mass spectrometry (GC-MS) technique for detection of sympathomimetic amines following urinary extraction is proposed. Amphetamine, phentermine, ephedrine, mephenorex, methylphenidate, benzphetamine, clobenzorex and internal standard (fenfluramine) are extracted from urines at pH 7.0 using elution by chloroform-isopropanol on C18 cartridges. Derivatization followed by GC-MS analysis allows identification of these drugs founded on relative retention times and mass spectra. The quantitation limit for derivatizable drugs was found to be 200 ng/ml and 500 ng/ml for underivatizable drugs.

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

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

The present study aimed to investigate the diagnostic and prognostic importance of oxidative stress biomarkers and acute phase proteins in urinary tract infection (UTI) in camels. We describe the clinical, bacteriological and biochemical findings in 89 camels. Blood and urine samples from diseased (n = 74) and control camels (n = 15) were submitted to laboratory investigations. The urine analysis revealed high number of RBCS and pus cells. The concentrations of serum and erythrocytic malondialdehyde (sMDA & eMDA), Haptoglobin (Hp), serum amyloid A (SAA), Ceruloplasmin (Cp), fibrinogen (Fb), albumin, globulin and interleukin 6 (IL-6) were higher in diseased camels when compared to healthy ones. Catalase, super oxide dismutase and glutathione levels were lower in diseased camels when compared with control group. Forty one of 74 camels with UTI were successfully treated. The levels of malondialdehyde, catalase, super oxide dismutase, glutathione, Hp, SAA, Fb, total protein, globulin and IL-6 were associated with the odds of treatment failure. The MDA showed a great sensitivity (Se) and specificity (Sp) in predicting treatment failure (Se 85%/Sp 100%) as well as the SAA (Se 92%/Sp 87%) and globulin levels (Se 85%/Sp 100%) when using the cutoffs that maximizes the sum of Se + Sp. Multivariate logistic regression analysis revealed that two models had a high accuracy to predict failure with the first model including sex, sMDA and Hp as covariates (area under the receiver operating characteristic curve (AUC) = 0.92) and a second model using sex, SAA and Hp (AUC = 0.89). Conclusively, the oxidative stress biomarkers and acute phase proteins could be used as diagnostic and prognostic biomarkers in camel UTI management. Efforts should be forced to investigate such biomarkers in other species with UTI.

Grapes and their associated phytochemicals have been investigated for beneficial effects on cardiovascular health, cancer prevention, and other chronic diseases, but the effect of grape consumption on bone health has not been fully determined. We previously found short-term benefits of grape products on reducing bone turnover in ovariectomized rats. The objective of this study was to determine the long-term benefits of a grape-enriched diet on bone in ovariectomized rats. Rats were ovariectomized at 3 mo of age and were administered a single dose of (45)Ca to prelabel bones at 4 mo of age. After a 1-mo equilibration period, baseline urinary (45)Ca excretion was determined. Rats (n = 22/group) were then randomly assigned to a modified AIN93M diet containing 25% freeze-dried grape powder or to a control diet for 8 wk. Urinary (45)Ca excretion was monitored throughout the study to determine changes in bone (45)Ca retention. Calcium balance was assessed after 1 and 8 wk of consuming the experimental diets, and a calcium kinetic study was performed at 8 wk. After 8 wk, femurs were collected for micro-computed tomographic imaging, 3-point bending, and reference point indentation. Rats fed the grape-enriched diet had 44% greater net bone calcium retention than did rats fed the control diet. There were no differences in calcium balance due to diet at either week 1 or week 8, but there was a significant increase in net calcium absorption (10.6%) and retention (5.7%) from week 1 to week 8 in the grape-enriched diet group only. Grape-enriched diet-fed rats had 3% greater cortical thickness and 11% greater breaking strength. There were no differences in femur bone mineral density, trabecular microarchitecture, or reference point indentation variables due to diet. This study of ovariectomized rats indicates that the consumption of grape products may improve calcium utilization and suppress bone turnover, resulting in improvements in bone quality. © 2015 American Society for

The syndrome of immunodepression is the bed of multiple infections of which urinary infections. The goal of this study was to determine the aspects clinical and bacteriological urinary infections during the AIDS with the service of the infectious diseases of the hospital of the Point G of February 1, 2003 to June 30 2005. The diagnosis of the urinary infection was retained on the basis of bacteria number > or =10(4) bacteriury and or leucocytes count > or =10(5)/mm3. The prevalence of the urinary infection was estimated at 8.85%. The principal clinical aspects were a symptomatic pyelonephritis 73.5%, the leucocytiury 11.8%, the cystitis 8.8%, and acute prostatitis 5.9%. Escherichia coli was the most frequent bacterium (46.7%). The sensitivity of the germs was 91.7% with the aminosides, 90.9% with the fluoroquinolones, from 63.6 to 80% respectively with the cephalosporines of first and second generation. Resistance to ampicilline, chloramphenicol and sulfamides was about 72 and 80%. The systematic research of the urinary infection is necessary during the AIDS and the antibiotherapy of choice in first intention in absence of etiologic possibility of diagnosis should be the aminosides and or the fluoroquinolones.

When a patient presents with acute voiding dysfunction without a typical skin rash, it may be difficult to make a diagnosis of herpes zoster. Here, we present a case of scrub typhus in a 25-year-old man with the complication of urinary dysfunction. The patient complained of loss of urinary voiding sensation and constipation. After eight days, he had typical herpes zoster eruptions on the sacral dermatomes and hypalgesia of the S1-S5 dermatomes. No cases of dual infection with varicella zoster virus and Orientia tsutsugamushi were found in the literature. In the described case, scrub typhus probably induced sufficient stress to reactivate the varicella zoster virus. Early recognition of this problem is imperative for prompt and appropriate management, as misdiagnosis can lead to long-term urinary dysfunction. It is important that a diagnosis of herpes zoster be considered, especially in patients with sudden onset urinary retention.
