What Are the Short-term Benefits and Potential Harms of Therapeutic Modalities for the Management of Overactive Bladder Syndrome in Women? A Review of Evidence Under the Auspices of the European Association of Urology, Female Non-neurogenic Lower Urinary Tract Symptoms Guidelines Panel.

CONTEXT: Overactive bladder syndrome (OAB) is highly prevalent among women and has a negative impact on their quality of life. The current available treatments for OAB symptoms include conservative, pharmacological, or surgical modalities. OBJECTIVE: To provide an updated contemporary evidence document regarding OAB treatment options and determine the short-term effectiveness, safety, and potential harms of the available treatment modalities for women with OAB syndrome. EVIDENCE ACQUISITION: The Medline, Embase, and Cochrane controlled trial databases and clinicaltrial.gov were searched for all relevant publications up to May 2022. The risk of bias assessment followed the recommended tool in the Cochrane Handbook for Systematic Reviews of Interventions, and quality of evidence was assessed using the modified Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria. A meta-analysis was performed where appropriate. EVIDENCE SYNTHESIS: Antimuscarinics and beta-3 agonists were significantly more effective than placebo across most outcomes, with beta-3 agonists being more effective at reducing nocturia episodes and antimuscarinics causing significantly higher adverse events. Onabotulinumtoxin-A (Onabot-A) was more effective than placebo across most outcomes, but with significantly higher rates of acute urinary retention/clean intermittent self-catheterisation (six to eight times) and urinary tract infections (UTIs; two to three times). Onabot-A was also significantly better than antimuscarinics in the cure of urgency urinary incontinence (UUI) but not in the reduction of mean UUI episodes. Success rates of sacral nerve stimulation (SNS) were significantly higher than those of antimuscarinics (61% vs 42%, p = 0.02), with similar rates of adverse events. SNS and Onabot-A were not significantly different in efficacy outcomes. Satisfaction rates were higher with Onabot-A, but with a higher rate of recurrent UTIs (24% vs 10%). SNS was associated with 9% removal rate and 3% revision rate. CONCLUSIONS: Overactive bladder is a manageable condition, with first-line treatment options including antimuscarinics, beta-3 agonists, and posterior tibial nerve stimulation. Second-line options include Onabot-A bladder injections or SNS. The choice of therapies should be guided by individual patient factors. PATIENT SUMMARY: Overactive bladder is a manageable condition. All patients should be informed and advised on conservative treatment measures in the first instance. The first-line treatment options for its management include antimuscarinics or beta-3 agonists medication, and posterior tibial nerve stimulation procedures. The second-line options include onabotulinumtoxin-A bladder injections or sacral nerve stimulation procedure. The therapy should be chosen based on individual patient factors.

European Association of Urology Guidelines on the Diagnosis and Management of Female Non-neurogenic Lower Urinary Tract Symptoms. Part 1: Diagnostics, Overactive Bladder, Stress Urinary Incontinence, and Mixed Urinary Incontinence.

CONTEXT: Female lower urinary tract symptoms (LUTS) are a common presentation in urological practice. Thus far, only a limited number of female LUTS conditions have been included in the European Association of Urology (EAU) guidelines compendium. The new non-neurogenic female LUTS guideline expands the remit to include these symptoms and conditions. OBJECTIVE: To summarise the diagnostic section of the non-neurogenic female LUTS guideline and the management of female overactive bladder (OAB), stress urinary incontinence (SUI), and mixed urinary incontinence (MUI). EVIDENCE ACQUISITION: New literature searches were carried out in September 2021 and evidence synthesis was conducted using the modified GRADE criteria as outlined for all EAU guidelines. A new systematic review (SR) on OAB was carried out by the panel for the purposes of this guideline. EVIDENCE SYNTHESIS: The important considerations for informing guideline recommendations are presented, along with a summary of all the guideline recommendations. CONCLUSIONS: Non-neurogenic female LUTS are an important cause of urological dysfunction. Initial evaluation, diagnosis, and management should be carried out in a structured and logical fashion based on the best available evidence. This guideline serves to present this evidence to health care providers in an easily accessible and digestible format. PATIENT SUMMARY: This report summarises the main recommendations from the European Association of Urology guideline on symptoms and diseases of the female lower urinary tract (bladder and urethra) not associated with neurological disease. We cover recommendations related to diagnosis of these conditions, as well as the treatment of overactive bladder, stress urinary incontinence, and mixed urinary incontinence.

CONTEXT: Female lower urinary tract symptoms (LUTS) are a common presentation in urological practice. Thus far, only a limited number of female LUTS conditions have been included in the European Association of Urology (EAU) guidelines compendium. The new non-neurogenic female LUTS guidelines expand the remit to include these symptoms and conditions. OBJECTIVE: To summarise the management of underactive bladder (UAB), bladder outlet obstruction (BOO), and nocturia in females. EVIDENCE ACQUISITION: The literature search was updated in September 2021 and evidence synthesis was conducted using modified GRADE approach as outlined for all EAU guidelines. A new systematic review on BOO was carried out by the panel for purposes of this guideline. EVIDENCE SYNTHESIS: The important considerations for informing guideline recommendations are presented, along with a summary of all the guideline recommendations. CONCLUSIONS: Non-neurogenic female LUTS are an important presentation of urological dysfunction. Initial evaluation, diagnosis, and management should be carried out in a structured and logical fashion on the basis of the best available evidence. This guideline serves to present this evidence to practising urologists and other health care providers in an easily accessible and digestible format. PATIENT SUMMARY: This report summarises the main recommendations from the European Association of Urology guideline on symptoms and diseases of the female lower urinary tract (bladder and urethra) not associated with neurological disease. We cover recommendations related to the treatment of underactive bladder, obstruction of the bladder outlet, and nighttime urination.

Functional outcomes of vaginal surgery for urethral extrusion of mid-urethral tape in women.

INTRODUCTION AND HYPOTHESIS: We aim to determine the presentation of and immediate and longer-term outcomes of vaginal surgical excision of urethral extrusion of mid-urethral tape (MUT). METHODS: We performed a retrospective analysis of all patients with urethral extrusion of MUT having vaginal surgical excision between 2007 and 2018. The MUT was removed either partially (via vaginal approach) or completely (via combined vaginal and laparoscopic approach). Functional outcomes and any re-interventions are described. RESULTS: Thirty-four patients of median age 53 (range 34-82) years were identified. Preoperative symptomatic recurrent/persistent urinary incontinence was present in 29/34(85%) with 24/34(71%) women having recurrent/persistent stress urinary incontinence (SUI) or stress predominant mixed urinary incontinence (s-MUI) on urodynamics. Vaginal surgical excision was performed alone in 33/34(97%) women and in combination with laparoscopic removal of abdominopelvic MUT in 1/34(3%) woman. In the longer term vaginal/urethral pain resolved or improved in all 15/15(100%) patients presenting with this complaint whilst patient reported poor flow resolved in 8/9 (89%) women. Twenty-eight of 34 women (82%) had persistent/recurrent SUI or s-MUI following MUT excision. Twenty-four of 34 women (71%) had further SUI surgery with cure or improvement of SUI in 20/24 (83%) patients. CONCLUSIONS: The outcome of vaginal surgical excision of the MUT was cure or improvement of pain in 100% and resolution of poor flow in 89% women. Recurrent/persistent SUI or s-MUI was present in 82% following removal as compared to 71% women prior to removal. Of the 71% of women electing to have further surgery for recurrent/persistent SUI/s-MUI, 83% were dry or improved afterwards.

Diagnostic Tests for Female Bladder Outlet Obstruction: A Systematic Review from the European Association of Urology Non-neurogenic Female LUTS Guidelines Panel.

CONTEXT: Female bladder outlet obstruction (fBOO) is a relatively uncommon condition compared with its male counterpart. Several criteria have been proposed to define fBOO, but the comparative diagnostic accuracy of these remains uncertain. OBJECTIVE: To identify and compare different tests to diagnose fBOO through a systematic review process. EVIDENCE ACQUISITION: A systematic review of the literature was performed according to the Cochrane Handbook and Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist. The EMBASE/MEDLINE/Cochrane databases were searched up to August 4, 2020. Studies on women ≥18 yr of age with suspected bladder outlet obstruction (BOO) involving diagnostic tests were included. Pressure-flow studies or fluoroscopy was used as the reference standard where possible. Two reviewers independently screened all articles, searched reference lists of retrieved articles, and performed data extraction. The risk of bias was assessed using Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2). EVIDENCE SYNTHESIS: Overall, 28 nonrandomised studies involving 10 248 patients were included in the qualitative analysis. There was significant heterogeneity regarding the characteristics of women included in BOO cohorts (ie, mixed cohorts including both anatomical and functional BOO). Pressure-flow studies ± fluoroscopy was evaluated in 25 studies. Transperineal Doppler ultrasound was used to evaluate bladder neck dynamics in two studies. One study tested the efficacy of transvaginal ultrasound. The urodynamic definition of fBOO also varied amongst studies with different parameters and thresholds used, which precluded a meta-analysis. Three studies derived nomograms using the maximum flow rate (Qmax) and voiding detrusor pressure at Qmax. The sensitivity, specificity, and overall accuracy ranges were 54.6-92.5%, 64.6-93.9%, and 64.1-92.2%, respectively. CONCLUSIONS: The available evidence on diagnostic tests for fBOO is limited and heterogeneous. Pressure-flow studies ± fluoroscopy remains the current standard for diagnosing fBOO. PATIENT SUMMARY: Evidence on tests used to diagnose female bladder outlet obstruction was reviewed. The most common test used was pressure-flow studies ± fluoroscopy, which remains the current standard for diagnosing bladder outlet obstruction in women. TAKE HOME MESSAGE: The available evidence on diagnostic tests for female bladder outlet obstruction is limited and heterogeneous. The most common test used was video-urodynamics, which remains the current standard for diagnosing bladder outlet obstruction in women.

Post-prostatectomy Lymphocoele Presenting With Renal Failure.

Since its advent in 2001, robotic-assisted laparoscopic prostatectomy has become the gold standard treatment for the management of localized prostate cancer. Pelvic lymphocoele is most commonly found after gynecological or renal transplant surgery or following extensive pelvic lymphadenectomy. Its formation following prostatectomy is not uncommon1 but it seldom causes major complications or morbidity.2 We present a case of a 66-year-old man who presented with left-sided abdominal pain, a palpable infra-umbilical mass, and renal failure. He was initially presumed to have high pressure chronic retention however catheterization did not result in any improvement in his renal function. Further investigations revealed a large lymphocoele causing bilateral ureteric obstruction with resultant hydronephrosis.

Nonantibiotic prevention and management of recurrent urinary tract infection.

Urinary tract infections (UTIs) are highly prevalent, lead to considerable patient morbidity, incur large financial costs to health-care systems and are one of the most common reasons for antibiotic use worldwide. The growing problem of antimicrobial resistance means that the search for nonantibiotic alternatives for the treatment and prevention of UTI is of critical importance. Potential nonantibiotic measures and treatments for UTIs include behavioural changes, dietary supplementation (such as Chinese herbal medicines and cranberry products), NSAIDs, probiotics, D-mannose, methenamine hippurate, estrogens, intravesical glycosaminoglycans, immunostimulants, vaccines and inoculation with less-pathogenic bacteria. Some of the results of trials of these approaches are promising; however, high-level evidence is required before firm recommendations for their use can be made. A combination of these agents might provide the optimal treatment to reduce recurrent UTI, and trials in specific population groups are required.

The effects of recreational ketamine cystitis on urinary tract reconstruction - a surgical challenge.

OBJECTIVES: To identify the rate of postoperative complications in patients who require surgical reconstruction for ketamine-induced urinary tract dysfunction and to identify any predictors for poor postoperative outcome with subsequent management strategies. PATIENTS AND METHODS: A retrospective review of data collected between 2007 and 2017 of all patients with ketamine-induced urinary tract disease was performed. Evaluation included computed tomography urogram, cystoscopy, and biopsy. Indications and outcomes for surgical intervention were assessed. RESULTS: In all, 44 patients were identified of which 68% were male. The mean (range) age at presentation was 31 (23-55) years. All bladder biopsies confirmed an eosinophilic inflammatory infiltrate. A significant proportion of patients (81.8%) were found to have reduced cystoscopic bladder capacity of <300 mL (mean 196, range 25-550 mL). In all, 29 patients were treated conservatively with a view to symptom resolution. Two patients underwent dilatation for urethral strictures. Four patients underwent repeated intra-detrusor onabotulinum toxin injection with minimal subjective symptom relief. Two of these patients proceeded to have major reconstruction. Indications for urinary tract reconstruction included intractable symptoms, high-pressure compliance loss with renal compromise and ureteric obstruction. Patients were advised to abstain from ketamine use for a minimum of 6 months prior to consideration of surgical intervention. A total of 14 patients underwent major reconstruction. Surgical intervention included ileal conduit urinary diversion, augmentation cystoplasty with or without Mitrofanoff channels, ureteric re-implantation, and cystectomy with neobladders. Complications included anastomotic leaks, ureteric strictures, adhesional small bowel obstruction, renal failure, and sepsis. Overall, complications occurred in 10/14 patients. CONCLUSION: In a tertiary high-volume reconstructive unit, ketamine patients were at high risk of significant perioperative complications. There did not appear to be any other common factor apart from their use of ketamine, and the significant inflammatory change associated with this. We recommend meticulous preoperative evaluation and multidisciplinary consultation for all patients to determine optimal treatment strategies.

Does the appearance of the urethral pressure profile trace correlate with the sphincter EMG findings in women with voiding dysfunction?

AIMS: Women with functional voiding dysfunction often experience a "catching" sensation when catheterising and are in general investigated with both urethral pressure profilometry (UPP) and sphincter electromyography (EMG). It is unknown whether the pattern of the UPP trace correlates with this sensation of "catching" or with sphincter EMG findings. METHODS: We reviewed the database of all women with voiding dysfunction who had undergone both sphincter EMG and UPP to assess for any relationship between pattern of UPP trace and "catching" on catheterization and/or sphincter EMG findings. UPP traces were classified as smooth or pulsatile and the EMG was classified as normal or abnormal. Statistical analysis was by Chi squared test for pulsatile UPP trace as a predictor of abnormal EMG. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of a pulsatile UPP trace for predicting abnormal EMG were also determined. These patients were asked to complete a telephone interview assessing discomfort on catheterization, particularly on catheter removal ("catching"). RESULTS: A total of 107 women of mean age 35.8 years underwent both sphincter EMG and UPP between 2011 and 2015. There was no significant association between "catching" on catheterization and pattern of UPP. There was a significant association between the presence of a pulsatile UPP and the finding of an abnormal EMG (P < 0.0001) The PPV of pulsatile UPP for abnormal EMG was 0.82 and the NPV of pulsatile UPP for abnormal EMG was 0.74. CONCLUSIONS: A pulsatile UPP trace is a sensitive predictor for abnormal EMG in patients with voiding dysfunction. There is no obvious correlation between a pulsatile UPP trace and a reported "catching" sensation on catheterization.

Buccal mucosal graft urethroplasty in men-risk factors for recurrence and complications: a third referral centre experience in anterior urethroplasty using buccal mucosal graft.

BACKGROUND: Urethral stricture disease is a challenging condition to treat and several approaches including direct visual internal urethrotomy (DVIU) and anastomotic or augmentation urethroplasties based on the use of flaps and graft have been reported. The aim of this study is to determine risk factors for stricture recurrence and complications in patients having buccal mucosal graft (BMG) urethroplasty for anterior urethral stricture under a single surgeon in a third referral centre in UK. METHODS: We conducted a retrospective review of a prospectively gathered database of 128 patients having various forms of BMG urethroplasty between 2001 and 2015. Success and failure in terms of stricture recurrence, patient demographics, stricture aetiology and anatomy, and the adverse outcomes of: post-micturition dribbling (PMD), erectile dysfunction (ED) >12 months and complications were recorded in order to determine risk factors for recurrent stricture and complications. RESULTS: The mean age of all patients was 42.8 years (range, 16-74 years). Average follow-up was 45 months (range, 3-159 months). The total re-stricture rate was 19% (24 men). PMD was reported in 16% (n=20) and ED in 12.5% (n=16). All ED was none organic and responded to oral PDE5 inhibitor treatment. Post-operative complications were reported in 16 patients (12.5%). The most frequent complications recorded were urinary fistula (n=4; 3.1%), graft contracture (n=4; 3.1%) and graft failure (n=4; 3.1%), all reported after penile urethroplasty. Univariate analysis indicated that age at surgery, stricture length, site and aetiology were all significant risk factors for stricture recurrence. On multivariate analysis penile site was the only significant independent variable for restricture. CONCLUSIONS: BMG urethroplasty represents a reliable therapeutic option for patient with urethral strictures with a success rate of 81% at 45 months of follow-up. Complications are more common in complex stricture of the penile urethra. On multivariate analysis penile site was the only significant independent variable for re-stricture.

Renal Tuberculosis Following Intravesical Bacillus Calmette-Guérin for High-grade Non-muscle-invasive Bladder Cancer.

A 47-year-old man presented to the urology department with visible hematuria. He was found to have a high-grade non-muscle-invasive transitional cell carcinoma of the bladder and was subsequently treated with intravesical Bacillus Calmette-Guérin instillations. On routine surveillance computed tomography scan following treatment, he was found to have multiple rounded areas of low density in the right kidney, suspicious for renal malignancy. He underwent renal biopsy that revealed necrotizing granulomatous inflammation suggestive of mycobacterial infection. He was successfully treated with antituberculosis therapy.

Urethral diverticulectomy with Martius labial fat pad interposition improves symptom resolution and reduces recurrence.

OBJECTIVE: To assess the presenting features and medium-term symptomatic outcomes in women having excision of urethral diverticulum with Martius labial fat pad (MLFP) interposition. PATIENTS AND METHODS: We reviewed our prospective database of all female patients having excision of a symptomatic urethral diverticulum between 2007 and 2015. Data on demographics, presenting symptoms and clinical features were collected, as well as postoperative outcomes. RESULTS: In all, 70 women with a mean (range) age of 46.5 (24-77) years underwent excision of urethral diverticulum with MLFP interposition. The commonest presenting symptoms were a urethral mass (69%), urethral pain (61%), and dysuria (57%). Pre-existing stress urinary incontinence (SUI) was present in 41% (29) of the women. After surgery, at a mean (SD) of 18.9 (16.4) months follow-up (median 14 months), complete excision of urethral diverticulum was achieved in all the women, with resolution of urethral mass, dysuria and dyspareunia in all, and urethral pain in 81%. Immediately after surgery, 10 (24%) patients reported de novo SUI, which resolved with time and pelvic floor muscle training such that at 12 months only five (12%) reported continued SUI. There was one symptomatic diverticulum recurrence (1.4%). CONCLUSIONS: The commonest presenting symptom of a female urethral diverticulum is urethral pain followed by dysuria and dyspareunia. Surgical excision with MLFP interposition results in complete resolution of symptoms in most women. The incidence of persistent de novo SUI in an expert high-volume centre is 12%.
