A Retrospective Case Series on Patient Satisfaction and Efficacy of Non-Surgical Lysis of Clitoral Adhesions.

BACKGROUND: Clitoral adhesions are characterized by adherence of preputial tissue to the glans clitoris and can be managed using a non-surgical approach in order to relieve symptoms of sexual dysfunction. AIM: To evaluate efficacy and patient satisfaction associated with the non-surgical lysis procedure in order to determine if it is an appropriate treatment for symptomatic clitoral adhesions. METHODS: The non-surgical lysis procedure is performed by using a fine Jacobsen mosquito forceps to separate the plane between the prepuce and the glans of the clitoris, removing smegma and/or keratin pearls from underneath the adhesions and allowing for visualization of the entire glans. A chart review of 61 women that were treated for clitoral adhesions using the non-surgical lysis procedure at 1 sexual medicine practice was performed and an online survey was sent to these patients. MAIN OUTCOME MEASURES: Encrypted survey responses were used to evaluate patient satisfaction as well as self-reported improvement in sexual functioning and pain before and after the procedure. RESULTS: 41 survey responses were received out of 61 eligible (67% response rate). A large majority reported improvement in pain (76%), sexual arousal (63%), and ability to achieve orgasm (64%) and no participants reported worsening in these symptoms. Of the 16 women that reported the inability to orgasm from external clitoral stimulation prior to the procedure, 6 (38%) were able to do so afterwards. Seventy-one percent of respondents reported improvement in their satisfaction with sex and 83% reported being satisfied with their decision to have the procedure. Ninety-three percent of participants reported that they would recommend this procedure to a friend with clitoral adhesions. CLINICAL IMPLICATIONS: The results of this study will help clinicians to recognize the non-surgical lysis procedure as a treatment option for clitoral adhesions. STRENGTHS & LIMITATIONS: This study is the first of its kind assessing a cohort of patients undergoing the non-surgical lysis procedure for clitoral adhesions. Its limitations include a small sample size from 1 clinic and lack of validated instrument to evaluate sexual function and pain before and after the procedure. CONCLUSION: Providers should regularly examine the clitoris of patients with symptoms of sexual dysfunction in order to determine if they have clitoral adhesions. The non-surgical lysis procedure may be a viable therapeutic option for these patients that has demonstrated both satisfaction and symptom relief. Myers MC, Romanello JP, Nico E, et al.

Radiation exposure during videourodynamic testing: Is dose reduction possible using a standardized protocol?

AIMS: To evaluate the impact of a protocol for standardized image capture during video urodynamics (VUD) on radiation exposure. Secondly, to categorize radiation exposure by condition warranting VUD and to identify clinical variables that correlate with increased radiation exposure. METHODS: One hundred fifty patients underwent VUD using our standardized protocol. All images were taken using low dose and pulsed settings. Four images are captured: one scout image, one filling image, one voiding image, and one post-void image. If the patient is unable to void with the catheter in place, the catheter is removed and a second image is taken during an attempt at unintubated flow. If vesicoureteral reflux (VUR) is identified, an alternate protocol is entered to document parameters. The mean radiation exposure measured in dose area product (DAP), fluoroscopy time, and number of images were noted and compared with previously published fluoroscopy data collected at our institution before protocol implementation. RESULTS: The mean fluoroscopy exposure after the implementation of our protocol was 273.5 mGy/cm2 taking 5.2 images in 4.5 seconds. Protocol implementation leads to a 51.2% reduction in radiation exposure calculated by mean DAP (P < .0001) and a 96.5% reduction in fluoroscopy time (P < .0001). The presence of VUR, fluoroscopy time, and body mass index (BMI) > 25 were associated with higher radiation exposure (P < .0001). CONCLUSION: Implementation and adherence to a standardized protocol for fluoroscopy led to a reduction in radiation exposure fluoroscopy time. The presence of VUR, fluoroscopy time, and BMI > 25 were associated with higher radiation exposure.

Early Detection of Ureteropelvic Junction Obstruction Using Signal Analysis and Machine Learning: A Dynamic Solution to a Dynamic Problem.

PURPOSE: We sought to define features that describe the dynamic information in diuresis renograms for the early detection of clinically significant hydronephrosis caused by ureteropelvic junction obstruction. MATERIALS AND METHODS: We studied the diuresis renogram of 55 patients with a mean ± SD age of 75 ± 66 days who had congenital hydronephrosis at initial presentation. Five patients had bilaterally affected kidneys for a total of 60 diuresis renograms. Surgery was performed on 35 kidneys. We extracted 45 features based on curve shape and wavelet analysis from the drainage curves recorded after furosemide administration. The optimal features were selected as the combination that maximized the ROC AUC obtained from a linear support vector machine classifier trained to classify patients as with or without obstruction. Using these optimal features we performed leave 1 out cross validation to estimate the accuracy, sensitivity and specificity of our framework. Results were compared to those obtained using post-diuresis drainage half-time and the percent of clearance after 30 minutes. RESULTS: Our framework had 93% accuracy, including 91% sensitivity and 96% specificity, to predict surgical cases. This was a significant improvement over the same accuracy of 82%, including 71% sensitivity and 96% specificity obtained from half-time and 30-minute clearance using the optimal thresholds of 24.57 minutes and 55.77%, respectively. CONCLUSIONS: Our machine learning framework significantly improved the diagnostic accuracy of clinically significant hydronephrosis compared to half-time and 30-minute clearance. This aids in the clinical decision making process by offering a tool for earlier detection of severe cases and it has the potential to reduce the number of diuresis renograms required for diagnosis.

Survival and secondary interventions following treatment for locally-advanced prostate cancer.

INTRODUCTION: The utility of radical prostatectomy (RP) for locally-advanced prostate cancer remains unknown. Retrospective data has shown equivalent oncologic outcomes compared to radiation therapy (RT). RP may provide local tumor control and prevent secondary interventions from local invasion, and may decrease costs. MATERIALS AND METHODS: Using SEER-Medicare data from 1995-2011 we identified men with locally-advanced prostate cancer undergoing RP or RT. Rates of post-treatment diagnoses and interventions were identified using ICD-9 and CPT codes. Skeletal related events (SRE), androgen deprivation therapy (ADT) utilization, all-cause mortality, prostate cancer-specific mortality, and costs were compared. RESULTS: A total of 8367 men with locally-advanced prostate cancer were identified (6200 RP, 2167 RT). RT was associated with increased urinary obstruction, hematuria, infection, and cystoscopic intervention while RP was associated with increased urethral stricture intervention and erectile dysfunction. Compared to RT, RP was associated with decreased all-cause mortality (3.1 versus 5.2 deaths/100-person-years, p < 0.001), prostate cancer-specific mortality (0.8 versus 2.0 deaths/100-person-years, p < 0.001), SREs (2.0 versus 3.4 events/100 person-years, p < 0.001), and ADT utilization overall (7.4 versus 33.8 doses/100-person-years, p < 0.001) and > 3 years after treatment (3.6 versus 4.6 doses/100-person-years, p < 0.001). Overall and cancer specific costs were significantly lower for RP versus RT. CONCLUSIONS: RT for locally-advanced prostate cancer has a higher incidence of mortality, secondary diagnoses and interventions, SRE, and ADT utilization compared to RP. This may lead to increased costs and have implications for quality of life. Our findings support the utility of RP in appropriately selected men with locally-advanced prostate cancer given the possible decreased morbidity and survival benefit.

Prediction of Clinical Outcomes in Prenatal Hydronephrosis: Importance of Gravity Assisted Drainage.

PURPOSE: In infants with SFU (Society for Fetal Urology) grade 3-4 congenital hydronephrosis, 99mTc-mercaptoacetyltriglycine diuretic renography assesses differential function and drainage half-time. We routinely also include the percent of radiotracer drained after 30 minutes of diuresis as well as after 15 minutes with the patient in the upright position. We investigated whether any 1 or more of these parameters on initial diuretic renography predicts persistent or worsening drainage parameters. MATERIALS AND METHODS: Infants 6 months or younger with grade 3-4 congenital hydronephrosis who presented between January 2009 and December 2014 were identified from billing data and included in analysis if they underwent at least 1 baseline diuretic renography. Those with structural anomalies were excluded from study. Baseline and followup differential function, diuresis half-time, clearance at 30 minutes and clearance with the patient upright were abstracted and comparisons were made between those with initially indeterminate diuresis half-time who underwent pyeloplasty vs those showing spontaneous improvement. RESULTS: A total of 74 patients (82 renal units) with presumed ureteropelvic junction obstruction met inclusion/exclusion criteria. All 10 renal units with initial diuresis half-time less than 5 minutes resolved spontaneously and all 25 renal units with initial diuresis half-time greater than 75 minutes underwent pyeloplasty. Therefore, we defined the indeterminate group as the 47 renal units with initial half-time between 5 and 75 minutes. Of those 47 renal units with indeterminate initial diuresis half-time 23 (47%) underwent pyeloplasty and 25 (53%) resolved spontaneously. Indications for pyeloplasty included worsening in 17 cases, persistent obstruction in 4 and urinary tract infection in 1. Among renal units with indeterminate drainage clearance while upright and clearance at 30 minutes were the only variables that differed significantly between surgical cases and those that resolved spontaneously. CONCLUSIONS: Radiotracer clearance with the patient upright and clearance at 30 minutes are more predictive of surgical management than diuresis half-time or differential function for renal units with indeterminate drainage. They should be included in the standard assessment of ureteropelvic junction obstruction.

Impact of active surveillance on pathology and nerve sparing status.

INTRODUCTION: We assessed whether, in comparison to immediate surgery, a time delay in performing radical prostatectomy (RP) in patients electing to undergo a period of active surveillance (AS) of low grade prostate cancer, is associated with adverse pathologic features, biochemical recurrence and the ability to perform effective nerve sparing surgery. MATERIALS AND METHODS: From our RP database of 2769 patients, we identified 41 men under AS who subsequently underwent RP. This study group was compared to control group A (164 patients who chose RP rather than AS), matched for prostate-specific antigen (PSA) and initial diagnostic biopsy characteristics. With time, PSA and biopsy characteristics in the AS study group changed, prompting these men to undergo RP. These changes were matched to create a separate control group B (123 patients most of whom did not meet AS criteria). The incidence of nerve sparing surgery, pathologic features, and biochemical recurrence were compared. Outcome variables were compared using Chi-square tests of proportions. Fisher's Exact test was used for recurrence rates due to the low expected frequencies in some cells. RESULTS: Compared with control group A, the AS patients experienced higher rates of Gleason score upgrading (33/41; 81.1% versus 76/164; 46.3%, p < 0.001), biochemical recurrence (5/41; 11.4% versus 2/164; 1.3%, p = 0.012) and lower rates of bilateral nerve sparing surgery (31/41; 75.6% versus 154/164; 93.9%, p < 0.001). Control group B and active surveillance group were comparable across all indices measured. CONCLUSIONS: Delaying RP, through undergoing a period of AS, had a significant negative impact on the incidence of bilateral nerve sparing surgery and adverse pathologic features when compared to patients with similar parameters at the time of diagnosis. Close monitoring and surveillance biopsies did not improve pathologic outcomes compared to patients from whom a single diagnostic biopsy was obtained (and were not candidates for AS), and who subsequently underwent immediate surgery.

A Cost Savings Analysis of Topical Estrogen Therapy in Urinary Tract Infection Prevention Among Postmenopausal Women.

INTRODUCTION: UTIs are some of the most common infections in geriatric patients, with many women experiencing recurrent infections after menopause. In the US, annual UTI-related costs are $2 billion, with recurrent infections creating a significant economic burden. Given the data published on topical estrogen in reducing the number of infections for postmenopausal women with recurrent UTI, we sought to evaluate how this would translate to cost savings. METHODS: We performed a systematic literature review of UTI reduction secondary to topical estrogen utilization in postmenopausal female patients. The cost per UTI was determined based on published Medicare spending on UTI per beneficiary, weighted on reported likelihood of complicated and resistant infections. For a patient with recurrent infections, topical estrogen therapy reported on average can reduce infections from 5 to 0.5 to 2 times per person per year. RESULTS: At a calculated cost per UTI of $1222, the reduction in UTI spending can range between $3670 and $5499 per beneficiary per year. Per-beneficiary spending on topical estrogen therapies was $1013 on average ($578-$1445) in 2020. After including the cost of the therapy, overall cost savings for topical estrogen therapies were $1226 to $4888 annually per patient. CONCLUSIONS: Topical estrogens are a cost-conscious way to improve the burden of UTI on postmenopausal women with the potential for billions of dollars in Medicare savings. System-wide efforts should be made to have these therapies available as prophylaxis for postmenopausal patients and to ensure they are affordable for patients.

Unmet Needs in Complicated Urinary Tract Infections: Challenges, Recommendations, and Emerging Treatment Pathways.

While urinary tract infections (UTIs) are one of the most common types of infections globally, the wide variety of presentations and of severity of disease can make it difficult to manage. The definition for uncomplicated UTIs (uUTIs) is generally regarded as UTIs in healthy, non-pregnant women whereas all other UTIs are considered complicated. There is, however, a lack of consensus definition of complicated UTIs (cUTIs), leading to global differences in management. In addition, the patients who develop complicated UTIs generally have other comorbidities that warrant more urgent intervention. One of the biggest challenges in treating cUTIs is the rise of antimicrobial resistance (AMR). While there have been recent drug approvals for new antibiotic to treat these resistant organisms, a multidisciplinary approach, including regulatory frameworks, provider education and public awareness campaigns, is crucial to limiting unnecessary treatments for asymptomatic bacteriuria (ASB) and uUTIs that can ultimately lead to more severe infections.

Bladder diverticulum caused by primary bladder neck obstruction.

Here, we report a case of a patient in their mid 30s who presented with an elevated creatinine and was found to have a massive bladder diverticulum. The patient underwent a robotic-assisted diverticulectomy. They were later found to have a primary bladder neck obstruction on video urodynamics, and subsequently, underwent bladder neck incision, leading to significant improvement in urinary symptoms. Primary bladder neck obstruction is an overlooked cause of bladder diverticulum. While cystoscopy and cross-sectional imaging are frequently used in the initial evaluation of bladder diverticula, in the absence of an anatomic obstruction such as prostate enlargement, video urodynamics should be performed to assess for primary bladder neck obstruction.

Recurrent vesicourethral anastomotic stenosis following treatment for prostate cancer: an effective endoscopic treatment using bipolar plasma button and triamcinolone.

PURPOSE: To evaluate the efficacy of deep bladder neck incision plus adjuvant Triamcinolone in the treatment of recurrent vesicourethral anastomotic stenosis following surgical treatment for prostate cancer. MATERIALS AND METHODS: A retrospective review of patients undergoing bladder neck incision from 2013 to 2019 was conducted. Patients who had previously undergone surgical treatment for prostate cancer and had failed treatment for bladder neck contracture were included. RESULTS: Twenty patients underwent deep bladder neck incision (BNI) with plasma button and adjuvant injection with a patency rate of 85%. Complete obliteration portended worst prognosis with 100% recurrence. CONCLUSIONS: Deep BNI with triamcinolone is a minimally morbid alternative for treatment of refractory vesicourethral anastomotic contractures.

Dorsal Onlay Oral Mucosa Graft Urethroplasty for Female Urethral Stricture.

OBJECTIVE: To describe and assess the outcomes of dorsal onlay oral mucosa graft urethroplasty for female urethral stricture. METHODS: We retrospectively reviewed the charts of all female patients who underwent dorsal onlay oral (buccal or lingual) mucosa urethroplasty for urethral stricture between 2011 and 2020 at two academic institutions. The primary endpoint was clinical success defined as any subjective improvement in LUTS self-assessed by the patients 1-3 months after catheter removal. Four surgeons performed the urethroplasties using a standardized technique: suprameatal incision, dissection and longitudinal opening of the dorsal aspect of the urethra, harvest of the oral mucosa graft, graft onlay sutured into the urethral opening. RESULTS: Nineteen patients were included. The clinical success rate was 94.7% at 1-3 months and 90.9% at 1 year. After a median follow-up of 12 months (range 1-49) there was one recurrence (5.3%), clinical success was achieved in 17 patients (89.5%) and both the maximum urinary flow rate and post void residual were significantly improved (15.2 vs 7.4 ml/s preoperatively; P = .008 and 71.5 vs 161.1 ml preoperatively; P = .001 respectively). The de novo stress urinary incontinence rate was 15.7% at 1-3 months and 9.1% at 1 year. CONCLUSION: Dorsal onlay oral mucosa graft urethroplasty for female urethral stricture appears feasible across multiple surgeons and is associated with a low perioperative morbidity, satisfactory functional outcomes and a low recurrence rate. Other series with larger sample size and longer follow-up are needed to confirm these findings.

Estimation of Urinary Frequency: Does Question Phrasing Matter?

PURPOSE: To evaluate if question phrasing and patient numeracy impact estimation of urinary frequency. MATERIALS AND METHODS: We conducted a prospective study looking at reliability of a patient interview in assessing urinary frequency. Prior to completing a voiding diary, patients estimated daytime, and nighttime frequency in 3 ways: (1) how many times they urinated (2) how many hours they waited in between urinations (3) how many times they urinated over the course of 4 hours. Numeracy was assessed using the Lipkus Numeracy Scale. RESULTS: Seventy-one patients completed the study. Correlation of estimates from questions 1, 2, and 3 to the diary were not statistically different. Prediction of nighttime frequency was better than daytime for all questions (correlation coefficients 0.751, 0.754, and 0.670 vs 0.596, 0.575, and 0.460). When compared to the diary, Question 1 underestimated (8.5 vs 9.7, P = .014) while Question 2 overestimated (11.8 vs 9.7, P = .027) recorded voids on a diary. All questions overpredicted nighttime frequency with 2.6, 2.9, and 3.9 predicted versus 1.6 recorded voids (P < .001). Although not statistically significant, for each question, the predicted frequency of numerate patients was more correlated to the diary than those of innumerate patients. CONCLUSION: When compared to a voiding diary for daytime urinary frequency, asking patients how many times they urinated underestimated, and asking patients how many hours they waited between urinations overestimated the number recorded voids. Regardless of phrasing, patients overestimated nighttime urination. Patients in our functional urology population have limited numeracy, which may impact accuracy of urinary frequency estimation.

Gel-Infused Translabial Ultrasound in the Evaluation of Female Urethral Stricture.

OBJECTIVES: The aims of this study were to describe our technique of gel-infused translabial ultrasound (GITLUS) to assess the female urethra for stricture and to highlight its utility when compared with other diagnostic techniques. METHODS: Consecutive patients presenting with prior diagnosis and/or suspicion for female urethral stricture underwent evaluation with uroflowmetry, postvoid residual, video urodynamics, and cystoscopy at the surgeon's discretion. All patients underwent GITLUS; 8-MHz curvilinear and 6-MHz linear high-frequency transducers were used to image the urethra from meatus to bladder neck while instilling 20 mL of lidocaine jelly to distend the urethra. Stricture location, length, caliber, and presence of periurethral fibrosis were assessed. Two healthy volunteers underwent GITLUS to serve as a comparison. RESULTS: Eight patients with suspected stricture underwent GITLUS. In all cases, GITLUS identified and characterized stricture and demonstrated periurethral fibrosis. Two healthy volunteers underwent GITLUS, which demonstrated a patent urethra and no evidence of fibrosis. Cystoscopy and video urodynamics on patients with stricture did not perform as well at identifying and fully assessing strictures. Six patients underwent definitive surgical repair, and GITLUS findings were confirmed. One patient had a postoperative GITLUS demonstrating resolution of the stricture and periurethral fibrosis. CONCLUSIONS: Gel-infused translabial ultrasound is a novel and accurate technique that in this small series appeared to identify and further characterize female urethral stricture in cases where it was utilized. Further research is needed to determine its role in preoperative planning and in providing a definitive diagnosis of stricture when other studies are equivocal.

Rectus Fascia Versus Fascia Lata for Autologous Fascial Pubovaginal Sling: A Single-Center Comparison of Perioperative and Functional Outcomes.

OBJECTIVE: To compare perioperative and functional outcomes of autologous fascia lata versus rectus fascia pubovaginal sling in female patients with stress urinary incontinence (SUI). METHODS: The charts of all patients undergoing pubovaginal sling for SUI from 2012 to 2017 at a single center were retrospectively reviewed. Patients were divided into 2 groups: those with the sling harvested from the fascia lata (FL group) and those with the sling harvested from the rectus fascia (RF group). RESULTS: Between 2012 and 2017, 105 women underwent pubovaginal slings: 21 using FL and 84 using RF. Operative time did not differ significantly between the FL and RF groups (84 vs 81.9 minutes; P=0.68). Estimated blood loss was lower in the FL group (91.7 vs 141.6 mL; P=0.04). There were more wound complications in the RF group, although this was not statistically significant (0% vs 14.3%; P=0.12). Overall complications were comparable between FL and RF groups (52.4% vs 48.9%; P=0.81), but the proportion of Clavien grade 2 or greater were higher in the RF group (4.8% vs 20.2%; P=0.11). Overall, wound complications accounted for 29.3% of postoperative complications in the RF group (12/41). Functional outcomes were comparable between FL and RF groups, with similar rates of patients without SUI symptoms after 1 month (82.4% vs 76.4%; P=0.74), 1 year (55.6% vs 63.8%; P=0.76), and at the latest follow-up (66.7% vs 65.8%; P=0.87). CONCLUSIONS: When compared with rectus fascia for pubovaginal sling, fascia lata may decrease perioperative morbidity, especially wound complications, without compromising functional outcomes.

The current state and the future of robotic surgery in female pelvic medicine and reconstructive surgery.

In this article, we review the current uses and future directions of robotic surgery in the field of female pelvic medicine and reconstructive surgery. Pelvic surgery is ideal for the use of surgical robots, which provide improved visualization and ease of suturing deep within the pelvis. Robots have been successfully used for the treatment of pelvic organ prolapse, in procedures such as sacrocolpopexy, sacrohysteropexy, and uterosacral ligament plication. Surgeons have used the robotic successfully to treat various etiologies of female pelvic pain including fibroids, endometriosis, and nerve entrapment. Robotic repair of iatrogenic injury has been described with excellent outcomes and avoidance of conversion to open surgery in the event of an injury caused using the robotic platform. While more data is needed on this topic, there has been increasing interest in using the robot for urologic reconstruction including repair of vesico-vaginal fistula, cystectomy, augmentation cystoplasty, and continent and non-continent diversions. Recently the use of the robot has been described in the treatment of stress urinary incontinence in females, with robotic placement of an artificial urinary sphincter. While robotic surgery is associated with increased cost, the outcomes of robotic surgery in female urology are promising. More studies that properly evaluate the benefits of robotic surgery as compared to open and laparoscopic approaches are needed.

Primary Bladder Neck Obstruction.

Primary bladder neck obstruction (PBNO) is a functional obstruction caused by abnormal opening of the bladder neck during the voiding phase of micturition. PBNO may present with a variety of symptoms including voiding symptoms (slow urinary stream, intermittent stream, incomplete emptying), storage symptoms (frequency, urgency, urgency incontinence, nocturia), and/or pelvic pain and discomfort. The diagnosis of PBNO can be made with videourodynamic testing, which demonstrates elevated voiding pressures with low flow, and fluoroscopic imaging demonstrating obstruction at the level of the bladder neck. Treatment options include conservative management with watchful waiting, pharmacologic management, and surgical intervention. In this article, we review the etiology, presentation, diagnosis, and treatment of PBNO in men, women, and children.

Effect of Radiation on Male Stress Urinary Incontinence and the Role of Urodynamic Assessment.

OBJECTIVE: To evaluate the effect of radiation on male stress urinary incontinence (SUI) and to assess the relative value of preoperative urodynamic (UDS) testing in radiated vs nonradiated men with SUI. METHODS: A retrospective chart review of all male patients with SUI who underwent UDS testing from 2010 to 2016 was performed. The impact of UDS findings on treatment decision making was assessed. UDS parameters and treatment patterns of radiated vs nonradiated patients were compared as well as the fates of storage symptoms in each group. RESULTS: Two hundred seven men were identified that underwent UDS with a clinical diagnosis of SUI. Sixty-five out of 207 (31.4%) were exposed to radiation as a treatment modality for prostate cancer. All patients that underwent UDS testing moved on to surgical correction of SUI, and the UDS findings did not alter plan to treat SUI in any patients. Men who were radiated prior to surgical correction of SUI were more likely to have detrusor overactivity (70% vs 38%, P <.0001) and had lower maximum cystometric capacity (255 vs 307.4 mL, P = .01) when compared to nonradiated on UDS. After artificial urinary sphincter or sling implantation, the proportion of patients requiring overactive bladder medications was higher in radiated vs nonradiated men (44.3% vs 25.3%; P = .01). CONCLUSION: Radiation therapy appears to increase the likelihood of bladder dysfunction in male patients with SUI. The UDS findings did not alter the plan to treat SUI in any patients in our series, and its role before SUI surgery in male patients, including those receiving radiation, may be limited.
