Abstract
INTRODUCTION To predict early continence recovery following radical prostatectomy (RP) using baseline demographic and clinical data, as well as dynamic transperineal ultrasound (TPUS) parameters of membranous urethral length (MUL). PATIENTS AND METHODS A retrospective CHECK-MUL (check of membranous urethral length) study was conducted. We evaluated 154 patients who underwent RP between August 2018 and April 2023. All patients underwent pre- and postoperative dynamic TPUS to measure MUL. Urinary continence was defined as the use of one safety pad or less 3 months post surgery. The International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) was used to assess urinary incontinence (UI). We used logistic regression to assess the association between MUL and early continence recovery. A multivariable logistic regression model was then constructed for the prediction of early continence recovery based on the MUL. RESULTS The median MUL observed pre- and postoperatively in this study were similar (14.6 mm and 12.9 mm). In the univariable logistic regression analysis, the pre- and postoperative MUL measured by TPUS (odds ratio (OR): 1.12; 95%-CI: 1.02-1.79; p = 0.05 and OR: 1.01; 95%-CI: 1.02-1.12; p < 0.01) directions were independent predictors of early continence recovery 3 months post surgery. In addition, age (OR: 1.23; 95%-CI: 1.11-1.42; p = 0.03), BMI (OR: 1.44; 95%-CI: 1.18-2.92; p = 0.05), and bilateral nerve sparing (OR: 1.24; 95%-CI: 1.02-1.9; p = 0.05) were independent predictors of urinary continence in univariable logistic regression models. Preoperative MUL >15 mm (95% CI 1.28-1.33; p = 0.03) and postoperative MUL >14 mm (95% CI 1.2-1.16; p = 0.05) were significantly associated with early continence recovery at 3 months post surgery. CONCLUSIONS The likelihood of continence recovery increases with membranous urethral length and decreases with age, BMI, and lack of nerve sparing. Preoperative MUL >15 mm and postoperative MUL >14 mm were significantly associated with early continence recovery at 3 months post surgery.

Abstract
OBJECTIVES To assess the impact of the learning curve (LC) on perioperative and long-term functional outcomes of a consecutive single-centre series of robot-assisted radical cystectomy with Padua intracorporeal orthotopic neobladder. PATIENTS AND METHODS Patients treated between 2013 and 2022 were included, with ≥1 year of follow-up. The entire cohort was divided in tertiles. Categorical and continuous variables were compared. Joinpoint regression analysis was used to identify significant changes over the decade in linear slope of the 1-year day- and night-time continence. Uni- and multivariable Cox regression analyses identified predictors of day- and night-time continence recovery. Day-time continence was defined as 'totally dry' (no pads), night-time continence as pad wetness ≤50 mL (one safety pad). RESULTS Overall, 200 patients were included. The mean hospital stay (P = 0.002) and 30-day complications (P = 0.04) significantly reduced over time; the LC significantly impacted on Trifecta achievement (P < 0.001). The 1-year day- and night-time continence probabilities displayed a significant improving trend (day-time continence annual average percentage change [AAPC] 11.45%, P < 0.001; night-time continence AAPC 10.05%, P = 0.009). The LC was an independent predictor of day- (hazard ratio [HR] 1.008; P < 0.001) and night-time continence (HR 1.004; P = 0.03) over time. CONCLUSION Patients at the beginning of the LC had significantly longer hospitalisations, more postoperative complications, and lower Trifecta rates. At the 10-year analyses, we observed a significant improving trend for both the 1-year day- and night-time continence probabilities, highlighting the crucial role of the LC. However, we are unable to assess the case volume needed to achieve a plateau in terms of day- and night-time continence rates.

Abstract
VACTERL association is defined as the nonrandom co-occurrence of a minimum of three of the following six key components: Vertebral anomalies, Anal atresia, Cardiac malformations, Tracheo-Esophageal fistula, Renal anomalies, and Limb abnormalities. Patients presenting with two components may also belong in the same spectrum. Additional components have been associated with VACTERL defects, including single umbilical artery, tethered spinal cord (TSC), and genital malformations. We observed a significant proportion of patients with bladder dysfunction (often called neurogenic bladder in the medical record) when reviewing a cohort of patients with VACTERL defects at our clinical center. Our finding calls attention to bladder dysfunction as an additional VACTERL phenotypic component. The prevalence of bladder dysfunction is greatest in those with genital anomalies, anorectal malformations, sacral dysplasia, renal anomalies, and TSC. We propose that patients with two or more VACTERL malformations be monitored for symptoms of bladder dysfunction if one or more of the identified risk factors are present until the achievement of urinary continence.

Abstract
INTRODUCTION Urinary dysfunctions are common sequelae following prostatectomy. This study aimed to discover factors that can predict urinary continence recovery at various time periods after robot-assisted laparoscopic radical prostatectomy (RARP). METHODS This was a retrospective analysis of data of 419 consecutive patients. Only patients followed up for ≥1 year were enrolled. An answer of "zero pad per day" in the Expanded Prostate Cancer Index Composite urinary assessment (question 5) denoted continence. Possible predictors of urinary continence recovery were evaluated at 3, 3-6, and 6-12 months after the operation. RESULTS Continence rates at 3, 6, and 12 months after RARP were 12.9%, 21.2%, and 40.2%, respectively. The proportions of patients using 0-1 pad were 54.2%, 75.7%, and 83.1% at 3, 6, and 12 months after RARP, respectively. Multivariable regression analysis revealed that a membranous urethral length (MUL) ≥11 mm was significantly associated with urinary continence recovery both within 3 months (odds ratio: 0.367, P = .003) and 3-6 months (odds ratio: 0.354, P = .001) after RARP. The analysis also revealed that, in patients with urinary continence at 6 months, a large prostate volume (odds ratio: 1.973, P = .044) and a high body mass index (odds ratio: 2.874, P = .027) were negative predictors of urinary continence recovery within 6-12 months. CONCLUSION A longer MUL was linked to urinary continence recovery within 6 months following RARP, whereas a large prostate volume and a high body mass index were adverse predictors of urinary continence recovery beyond 6 months.

Abstract
Nerve sparing (NS) is a surgical technique to optimize functional outcomes of radical prostatectomy (RP). However, it is not recommended in high risk (HR) cases because of the risk of a positive surgical margin that may increase the risk of cancer recurrence. In the last two decades there has been a change of perspective to the effect that in well-selected cases NS could be an oncologically safe option with better functional outcomes. Therefore, we aim to compare the functional outcomes and oncological safety of NS during RP in men with HR disease. A total of 1340 patients were included in this analysis, of which 12% (n = 158) underwent non-NSRP and 39% (n = 516) and 50% (n = 666) uni- and bilateral NSRP, respectively. We calculated a propensity score and used inverse probability of treatment weighting (IPTW) to balance the baseline characteristics of Pca patients undergoing non-NSRP and those having uni- and bilateral NSRP, respectively. NS improved functional outcomes; after IPTW, only 3% of patients having non-NSRP reached complete erectile function recovery (without erectile aid) at 24 months, whereas 22% reached erectile function recovery (with erectile aid), while 87% were continent. Unilateral NS increased the probability of functional recovery in all outcomes (OR 1.1 or 1.2, respectively), bilateral NS slightly more so (OR 1.1 to 1.4). NSRP did not impact the risk of any recurrence (HR 0.99, 95%CI 0.73-1.34, p = 0.09), and there was no difference in survival for men who underwent NSRP (HR 0.65, 95%CI 0.39-1.08). There was no difference in cancer-specific survival (0.56, 95%CI 0.29-1.11). Our study found that NSRP significantly improved functional outcomes and can be safely performed in carefully selected patients with HR-PCa without compromising long term oncological outcomes.

Abstract
Robotic-assisted radical prostatectomy (RARP) is the gold standard for localized prostate cancer. Several RARP approaches were developed and described over the years, aimed at improving oncological and functional outcomes. In 2010, Galfano et al described a new RARP technique, known as Retzius-sparing RARP (RS-RARP), a posterior approach through the Douglas space that spares the anterior support structures involved with urinary continence and sexual potency. This approach has been used increasingly in many centers around the world comparing its results with those of the most used standard anterior approach. Several randomized controlled trials, systematic reviews and meta-analyses demonstrated an important advantage relative to standard anterior RARP in terms of early urinary continence recovery, with comparable perioperative and long-term oncological outcomes. Several surgeons are concerned regarding RS-RARP because it appears to increase the risk of positive surgical margins (PSMs). However, this statement is based on low-certainty evidence. Indeed, the available studies compared the results of surgeons who had an initial experience with posterior RARP with those who had a solid experience with anterior RARP. Recent evidence strongly suggests that RS-RARP is feasible and safe not only in low- and intermediate-risk prostate cancer patient but also in challenging scenario such as high-risk setting, salvage prostatectomy and after transurethral resection of the prostate.

Abstract
Background: Numerous continence-sparing radical prostatectomy techniques have been developed to enhance postoperative early continence (EC) recovery; however, evidence regarding the best approach remains controversial. The objectives are to provide a critical appraisal of various prostatectomy techniques, based on the evidence of quality-assessed randomized control trials (RCTs); to summarize the immediate continence and the EC reported; and to propose a new standardization for continence outcomes reporting. Methods: Data acquired from five medical registries were reported to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. Evidence from published, English, full-text RCTs reporting postoperative urinary continence outcomes within 6 months from surgery was included. The heterogeneity of surgical techniques and continence definitions did not allow a meta-analysis. All RCTs were critically appraised, and quality assessed. Results: In total, 39 RCTs were included: 19 of 39 studies were low-quality RCTs, presenting small cohort, monocentric, or single-surgeon data. The best RCT-supported evidence is in favor of robot-assisted radical prostatectomy (RARP) compared with laparoscopic radical prostatectomy (LRP) and of the Retzius-sparing (RS) technique over the traditional prostatectomy. Other techniques such as bladder neck and puboprostatic ligament (PPL) preservation, posterior reconstruction with or without combination of anterior suspension technique, and nerve-sparing (NS) approach seem to enhance EC. Oppositely, the endopelvic fascia preservation, bladder neck mucosa eversion/plication/slings, and the selective ligature of dorsal venous complex (DVC) were not significantly associated with EC improvements. RCTs are lacking on pubovesical complex-sparing, seminal vesicle preservation, anterior reconstruction of the puboprostatic collar, musculofascial reconstruction, and DVC suspension to the periosteum of the pubic bone techniques. Conclusions: RARP and RS have high-quality evidence supporting their ability to enhance postoperative EC recovery. NS, bladder neck, and PPL preservation may contribute to better EC recovery, although the evidence level is low. Further multicenter RCTs are needed to establish the optimal combination of standard surgical techniques. A new continence outcome-reporting standardization was proposed.

Abstract
BACKGROUND We recently reported the importance of deep learning (DL) of pelvic magnetic resonance imaging in predicting the degree of urinary incontinence (UI) following robot-assisted radical prostatectomy (RARP). However, our results were limited because the prediction accuracy was approximately 70%. AIM To develop a more precise prediction model that can inform patients about UI recovery post-RARP surgery using a DL model based on intraoperative video images. METHODS AND RESULTS The study cohort comprised of 101 patients with localized prostate cancer undergoing RARP. Three snapshots from intraoperative video recordings showing the pelvic cavity (prior to bladder neck incision, immediately following prostate removal, and after vesicourethral anastomosis) were evaluated, including pre- and intraoperative parameters. We evaluated the DL model plus simple or ensemble machine learning (ML), and the area under the receiver operating characteristic curve (AUC) was analyzed through sensitivity and specificity. Of 101, 64 and 37 patients demonstrated "early continence (using 0 or 1 safety pad at 3 months post-RARP)" and "late continence (others)," respectively, at 3 months postoperatively. The combination of DL and simple ML using intraoperative video snapshots with clinicopathological parameters had a notably high performance (AUC, 0.683-0.749) to predict early recovery from UI after surgery. Furthermore, combining DL with ensemble artificial neural network using intraoperative video snapshots had the highest performance (AUC, 0.882; sensitivity, 92.2%; specificity, 78.4%; overall accuracy, 85.3%) to predict early recovery from post-RARP incontinence, with similar results by internal validation. The addition of clinicopathological parameters showed no additive effects for each analysis using DL, EL and simple ML. CONCLUSION Our findings suggest that the DL algorithm with intraoperative video imaging is a reliable method for informing patients about the severity of their recovery from UI after RARP, although it is not clear if our methods are reproducible for predicting long-term UI and pad-free continence.

Abstract
Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) allows the preservation of the structures advocated to play a crucial role in the continence mechanism. This study aims to evaluate the association between adjuvant radiation therapy (aRT) and urinary continence (UC) recovery after RS-RARP. For the purpose of the current study, all patients submitted to RS-RARP for prostate cancer (PCa) at a single high-volume European institution between January 2010 and December 2021 were identified. Only patients that harbored pT2 stage with positive surgical margins or pT3/pN1 stage with or without positive surgical margins were included in the analyses. Two groups of patients were identified as follows: patients who had undergone aRT and patients submitted to observation (no-aRT patients). As per definition, aRT was delivered within 1-6 months after surgery. After 1:1 propensity score matching, 124 aRT patients were compared with 124 no-aRT patients who continued standard follow-up protocol after surgery. UC recovery was 81 vs. 84% in aRT vs. no-aRT patients (p = 0.7). In multivariable Cox regression analyses, aRT did not reach the independent predictor status for UC recovery at 12 months. In the subgroup analysis including only aRT patients, only the nerve-sparing technique was independently associated with UC recovery at 12 months. Conversely, the type of aRT (IMRT/VMAT vs. 3D-CRT) did not reach the independent predictor status for UC recovery at 12 months. The current study is the first to address the association between aRT and UC recovery in patients treated with RS-RARP for PCa. Based on our data, aRT is not associated with worse UC recovery. In the cohort of patients treated with aRT, the nerve-sparing technique independently predicted UC recovery.

Abstract
Several efforts in recent years have been made to predict urinary continence (UC) recovery after radical prostatectomy. The aim of our study was to investigate the impact of surgical urethral length preservation (SULP) on urinary continence after LARP (laparoscopic-assisted radical prostatectomy). We retrospectively queried our datasets from May 2021 to May 2022. After the application of exclusion criteria, a total of 100 patients who underwent LARP for prostate cancer at our institution were enrolled. Through a sterile ruler inserted by a 12 mm trocar, the length of the membranous urethra spared during LARP was assessed intra-operatively. The baseline and peri- and postoperative data of patients were collected, and UC was defined as 0 or 1 on a safety pad. The median SULP was 20.5 mm (IQR, 14.5-25), and the median intraoperative EBL were 150 mL (IQR, 100-200). The Kaplan-Meier curve showed a significant difference at 20 mm, which was used as the cut-off value for SULP (log-rank test, p < 0.001). Multivariate Cox proportional hazards models showed that SULP and EBL < 250 mL were associated with UC recovery (all p < 0.02). Surgical urethral length preservation seemed to improve early UC recovery after LARP. Further multicentric studies are needed to confirm our findings.

Abstract
Background This study presents the procedure of single-port extraperitoneal transvesical approach to robot-assisted radical prostatectomy (SETvRARP) on the da Vinci Xi platform coupling with a 4-channel single port and evaluated the short-term outcomes in the first 72 prostate cancer (PCa) patients. Methods Seventy-two patients with localized PCa were enrolled. Each operation was conducted by the same single robotic surgery group in two centers using the da Vinci Xi system. Results The median operation time was 150 min, and the median estimated blood loss was 50 mL. All operations were successfully carried out without open conversion or transfusion. No ≥ Grade II complications were noted. Urethral catheters were routinely removed on postoperative day 7. Sixty-eight (94.4%) patients recovered to immediate urinary continence after surgery, with 72 (100%) patients achieving full continence on postoperative day 14. A positive surgical margin was observed in 15 (20.8%) patients. Postoperative urodynamic studies regarding peak urinary flow, bladder capacity, and residual urine were not statically different from the preoperative results. No biochemical recurrence was noted in all patients within the follow-up period. Postoperative erectile function was not statistically different from the preoperative results (P=0.1697). Conclusions SETvRARP using the da Vinci Xi system coupling with a 4-channel single port is a valid radical prostatectomy technique in well-selected PCa patients, resulting in superior postoperative recovery of urinary continence. Meanwhile, the outcomes in functional protection and cancer control need to be further investigated with a long-term follow-up duration.

Abstract
Aim and Objectives: We aimed to test the impact of age on long-term urinary continence (≥12 months) in patients undergoing robotic-assisted radical prostatectomy. Methods and Materials: We relied on an institutional tertiary-care database to identify the patients who underwent robotic-assisted radical prostatectomy between January 2014 and January 2021. Patients were divided into three age groups: age group one (≤60 years), age group two (61-69 years) and age group three (≥70 years). Multivariable logistic regression models tested the differences between the age groups in the analyses addressing long-term urinary continence after robotic-assisted radical prostatectomy. Results: Of the 201 prostate cancer patients treated with robotic-assisted radical prostatectomy, 49 (24%) were assigned to age group one (≤60 years), 93 (46%) to age group two (61-69 years) and 59 (29%) to age group three (≥70 years). The three age groups differed according to long-term urinary continence: 90% vs. 84% vs. 69% for, respectively, age group one vs. two vs. three (p = 0.018). In the multivariable logistic regression, age group one (Odds Ratio (OR) 4.73, 95% CI 1.44-18.65, p = 0.015) and 2 (OR 2.94; 95% CI 1.23-7.29; p = 0.017) were independent predictors for urinary continence, compared to age group three. Conclusion: Younger age, especially ≤60 years, was associated with better urinary continence after robotic-assisted radical prostatectomy. This observation is important at the point of patient education and should be discussed in informed consent.

Abstract
AIMS To identify the barriers and enablers perceived by hospital-based clinicians to providing evidence-based continence care to inpatients. DESIGN This was a cross-sectional study of inpatient clinicians using a questionnaire. METHODS Acute care and rehabilitation clinicians from 15 wards that admit patients after stroke at 12 hospitals (NSW = 11, Queensland =1, metropolitan = 4, regional = 8) were invited to complete an online questionnaire. The 58 questions (answered on a 5-point Likert scale) were aligned to 13 of the 14 domains of the Theoretical Domains Framework. Results were dichotomized into 'strongly agree/agree' and 'unsure/disagree/strongly disagree' and proportions were calculated. Data collection occurred between January 2019 and March 2019. RESULTS The questionnaire was completed by 291 participants with 88% being nurses. Barriers were found in nine domains including knowledge; skills; memory attention and decision making; emotion; environmental context and resources; behavioural regulation; social professional role; intensions, social influences; and beliefs about capabilities. Enablers were found in seven domains including goals; social influences; knowledge; skills; social, professional role and identity; reinforcement and beliefs about consequences. CONCLUSION This multi-site, multi-professional study that included predominantly nurses highlights the barriers and enablers to inpatient continence care. Future implementation studies in inpatient continence management should address these identified barriers and enablers to improve effectiveness of implementation of evidence-based care. IMPLICATIONS FOR THE PROFESSION This study highlights that although there are many barriers to ward nurses providing evidence-based continence care, there are also several enablers. Both should be addressed to improve practice. REPORTING METHOD We adhered to the Checklist for Reporting Results of Internet E-Surveys (CHERRIES) (Supplementary File 1). RELEVANCE TO CLINICAL PRACTICE Establishing barriers to practice gives a broader understanding of why practice does not occur and establishes areas where researchers and clinicians need to address in order to change behaviour.

Abstract
INTRODUCTION The prevalence of healthy bladder storage and emptying function in community-dwelling women is not well established. METHODS A planned secondary analysis of a US cross-sectional study designed to validate a bladder health instrument was conducted in women aged ≥18 years. A subset was invited to complete the novel 2-day bladder health diary capturing bladder storage and emptying experiences. Overall healthy bladder function was defined as ≤8 waking/daytime voids and ≤1 void during sleeping/nighttime; along with the absence of leakage, urgency, emptying difficulties (initiation, flow, efficacy, relief of urge sensation) and pain. Descriptive statistics of healthy bladder functions and regression models of factors associated with healthy function are reported. RESULTS Of the 383 invited, 237 (62%) eligible women returned complete dairies. Of these, 12% (29/237) met criteria for overall healthy bladder function. Most (96%) denied pain, 74% had healthy daytime and 83% had healthy nighttime voiding frequency, 64% were continent, 36% reported healthy emptying and 30% denied any urgency episodes. Middle income (odds ratio [OR]:95% confidence interval [CI] = 11.4:1.9-67.4 for $75k-$99 999 vs. $25 000-$49 999), Graduate education (4.8:1.4-17) and previously seeking treatment for bladder problems (OR:95%CI = 0.1; 0-0.9) were associated with overall healthy function. CONCLUSION The prevalence of overall healthy bladder function was very low based on our strict definition of health as measured on a 2-day diary. However, most women had healthy voiding frequency and denied pain or urinary leakage. Postvoid dribbling and urgency most commonly contributed to an overall unhealthy bladder. Further investigation is needed to determine whether these diary derived measures are meaningful for patient-oriented bladder health research.

Abstract
Prostate MRI has an important role in prostate cancer diagnosis and treatment, including detection, the targeting of prostate biopsies, staging and guiding radiotherapy and active surveillance. However, there are other ''less well-known'' applications which are being studied and frequently used in our highly specialized medical center. In this review, we focus on two research topics that lie within the expertise of this study group: (1) anatomical parameters predicting the risk of urinary incontinence after radical prostatectomy, allowing more personalized shared decision-making, with special emphasis on the membranous urethral length (MUL); (2) the use of three-dimensional models to help the surgical planning. These models may be used for training, patient counselling, personalized estimation of nerve sparing and extracapsular extension and may help to achieve negative surgical margins and undetectable postoperative PSA values.

Abstract
OBJECTIVE To evaluate the impact of sustainable functional urethral reconstruction (SFUR) on early recovery of urinary continence (UC) after robot-assisted radical prostatectomy. PATIENTS AND METHODS Overall, 96 patients with primary prostate cancer were randomised into the SFUR or standard group (n = 48 each). The primary outcome was the 1-month UC recovery. Secondary outcomes included short-term (≤3 months) UC recovery, urinary function, micturition-related bother, perioperative complications, and oncological outcomes. Kaplan-Meier curves and Cox proportional hazard models were used to assess the 3-month UC recovery. Generalised estimating equations were used to compare postoperative urinary function and micturition-related bother. RESULTS The 1-month UC recovery rates, median 24-h pad weights, and median operative time in the SFUR and standard groups were 73% and 49% (P = 0.017), 0 and 47 g (P = 0.001), and 125 and 103 min (P = 0.025), respectively. The UC recovery rates in the SFUR vs standard groups were 53% vs 23% at 1 week (P = 0.003), 53% vs 32% at 2 weeks (P = 0.038), and 93% vs 77% at 3 months (P = 0.025). The median time to UC recovery in the SFUR and standard groups was 5 and 34 days, respectively (log-rank P = 0.006); multivariable Cox regression supported this result (hazard ratio 1.73, 95% confidence interval 1.08-2.79, P = 0.024). Similar results were observed when UC was defined as 0 pads/day. Urinary function (P = 0.2) and micturition-related bother (P = 0.8) were similar at all follow-up intervals. The perioperative complication rates, positive surgical margin rates, and 1-year biochemical recurrence-free survival were comparable between both groups (all P > 0.05). CONCLUSION SFUR resulted in earlier UC recovery without compromising postoperative urinary function. Long-term validation and multicentre studies are required to confirm the results of this novel technique.

Abstract
Background and Objectives: To evaluate the efficacy of bladder-prostatic muscle reconstruction and bladder neck eversion anastomosis in the recovery of urinary continence after robot-assisted radical prostatectomy (RARP). Materials and Methods: From January 2020 to May 2022, 69 patients who underwent RARP in our hospital were recruited. Thirty-seven patients underwent RARP with the Veil of Aphrodite technique (control group). On the basis of the control group, 32 patients underwent bladder-prostatic muscle reconstruction and bladder neck eversion anastomosis during RARP (observation group). The recovery of urinary continence was followed up at 24 h and 1, 4, 12, and 24 weeks after catheter removal. Results: There were no significant differences in operative time (127.76 ± 21.23 min vs. 118.85 ± 24.71 min), blood loss (118.27 ± 16.75 mL vs. 110.77 ± 19.63 mL), rate of leakage (3.13% vs. 2.70%), rate of positive surgical margin (6.25% vs. 10.81%), or postoperative Gleason score [7 (6−8) vs. 7 (7−8)] between the observation group and the control group (p > 0.05). After catheter removal, the rates of urinary continence at 24 h, 1 week, 4 weeks, 12 weeks, and 24 weeks were 46.88%, 68.75%, 84.38%, 90.63%, and 93.75% in the observation group, respectively. Meanwhile, the rates of urinary continence in the control group were 21.62%, 37.84%, 62.16%, 86.49%, and 91.89%, respectively. There was a significant difference between the two groups (p = 0.034), especially at 24 h, 1 week, and 4 weeks after catheter removal (p < 0.05). Conclusions: Bladder-prostatic muscle reconstruction and bladder neck eversion anastomosis were beneficial to the recovery of urinary continence after RARP, especially early urinary continence.

Abstract
OBJECTIVES To assess the effects of posterior musculofascial reconstruction robot-assisted laparoscopic prostatectomy (PR-RALP) compared to no PR during standard RALP (S-RALP) for the treatment of clinically localised prostate cancer. PATIENTS AND METHODS We performed a systematic search with no restrictions including randomised controlled trials (RCTs) comparing variations of PR-RALP vs S-RALP for clinically localised prostate cancer. The quality of evidence was assessed on outcome basis according to Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach. Our search identified 13 records of eight unique RCTs, of which six were published studies, and two were abstract proceedings. There were 1085 randomised patients, of whom 963 completed the trials. All patients had either cT1c or cT2 or cT3a disease. RESULTS A PR-RALP may improve urinary continence 1 week after catheter removal compared to no PR (risk ratio [RR] 1.25, 95% confidence interval [CI] 0.90-1.73; I2 = 42%, five studies, 498 patients, low certainty of evidence [CoE]). A PR-RALP may have little to no effect on urinary continence 3 months after surgery compared to no PR (RR 0.98, 95% CI 0.84-1.14; I2 = 67%, six studies, 842 patients, low CoE). A PR-RALP probably results in little to no difference in serious adverse events compared to no PR (RR 0.75, 95% CI 0.29-1.92; I2 = 0%, six studies, 835 patients, moderate CoE). CONCLUSIONS This review found evidence that PR-RALP may improve early continence 1 week after catheter removal but not thereafter. Meanwhile, adverse event rates are probably not impacted and positive surgical margin rates are likely similar. There was no difference in our subgroup analysis for all outcomes with anterior reconstruction technique when combined with PR vs only PR.

Abstract
We aimed to assess the surgical and patient-reported outcomes of delayed anastomotic urethroplasty (DAU) for pelvic fracture urethral injury (PFUI). We included 211 male patients who underwent DAU for PFUI. DAU success was considered when the urethral lumen was sufficiently large for the passage of a flexible cystoscope, without additional treatment required. The patients completed the lower urinary tract symptoms (LUTS)-related quality of life (QOL) questionnaire (scores: 0, not at all; 1, a little; 2, somewhat; 3, a lot), EuroQol-5 dimensions (EQ-5D), and EQ-5D visual analog scale (EQ-VAS). Postoperative overall satisfaction was evaluated using the following responses: “very satisfied,” “satisfied,” “unsatisfied,” or “very unsatisfied.” DAU was successful in 95.3% cases, with a median postoperative follow-up duration of 48 months. Multivariate logistic regression analysis revealed that “greater blood loss” was an independent predictor of failed urethroplasty. Questionnaire responses were obtained from 80.1% patients. The mean LUTS-related QOL, EQ-5D score and EQ-VAS improved significantly from 2.8, 0.63 and 54.4 at baseline to 0.9, 0.81 and 76.6 postoperatively (p < 0.0001 for all parameters). Moreover, 35.5% and 59.2% of the patients responded being “satisfied” and “very satisfied,” respectively, with their DAU outcomes. DAU not only had a high surgical success rate, but also a significant beneficial effect on both LUTS-related QOL and overall health-related QOL.

Abstract
The management of male pelvic fracture urethral injury remains a urological challenge. Pelvic fracture urethral injury can be associated with sequelae, such as urethral gap, erectile dysfunction and urinary incontinence. Delayed anastomotic urethroplasty, the gold standard treatment for urethral gaps caused by pelvic fracture urethral injuries, is technically demanding, and reconstructive urologists should preoperatively obtain as much detailed anatomical information as possible. A combination of antegrade and retrograde urethrography is the fundamental preoperative evaluation, but it cannot accurately assess the urethral gap length, the degree of lateral prostatic displacement, the anatomical relationship of the urethra with its surrounding structures (such as the rectum and dorsal venous complex) or periurethral problems (such as minor fistulae or cavitation). To make up for these limitations of urethrography, magnetic resonance imaging has emerged as a non-invasive, multiplanar and high-resolution modality for the evaluation of pelvic fracture urethral injury. Magnetic resonance imaging has excellent soft-tissue contrast, and can clearly show the urethra and periurethral tissues without the effects of radiation, thus enabling clinicians to anticipate the required ancillary techniques for delayed anastomotic urethroplasty and to predict functional outcomes, such as erectile function and urinary continence, after delayed anastomotic urethroplasty. This review discusses the role of magnetic resonance imaging in the evaluation of pelvic fracture urethral injury and its impact on patient management.

Abstract
Background: The Retzius space-sparing robot-assisted radical prostatectomy (RS-RARP) has shown better results in urinary continence, but its efficacy and safety compared to conventional robot-assisted radical prostatectomy (c-RARP) remain controversial. Material and Methods: A research was conducted in Medline via PubMed, Cochrane Library, EMBASE, and Web of Science up to January 4, 2021, to identify studies comparing RS-RARP to c-RARP. We used RevMan 5.3 and STATA 14.0 for meta-analysis. Results: A total of 14 studies involving 3,129 participants were included. Meta-analysis showed no significant difference in positive surgical margins (PSMs), but the RS-RARP group had significantly higher PSM rates in the anterior site [odds ratio (OR) = 2.25, 95% CI: 1.22–4.16, P = 0.01]. Postoperative continence in RS-RARP group at 1 month (OR = 5.72, 95% CI: 3.56–9.19, P < 0.01), 3 months (OR = 6.44, 95% CI: 4.50–9.22, P < 0.01), 6 months (OR = 8.68, 95% CI: 4.01–18.82, P < 0.01), and 12 months (OR = 2.37, 95% CI: 1.20–4.70, P = 0.01) was significantly better than that in the c-RARP group. In addition, the RS-RARP group had a shorter console time (mean difference = −16.28, 95% CI: −27.04 to −5.53, P = 0.003) and a lower incidence of hernia (OR = 0.35, 95% CI: 0.19–0.67, P = 0.001). However, there were no significant differences in estimated blood loss, pelvic lymph node dissection rate, postoperative complications, 1-year-biochemical recurrence rate, and postoperative sexual function. Conclusions: Compared with c-RARP, RS-RARP showed better recovery of continence, shorter console time, and lower incidence of hernia. Although there was no significant difference in overall PSM, we suggest that the surgeon should be more careful if the lesion is in the anterior prostate.

Abstract
Introduction: MRI has helped clarify the relationship between pelvic anatomical structures and functional outcomes after robot-assisted radical prostatectomy (RARP). The objective of this study was to assess the impact of the bladder neck angle (BNA) measured by postoperative MRI on midterm recovery of urinary continence (UC) in patients undergoing RARP. Patients and Methods: This study retrospectively included 200 consecutive patients with prostate cancer who were treated by RARP and received MRI 3 months after RARP. Based on postoperative MRI, the BNA was measured as the angle between the anterior and posterior bladder walls. The midterm recovery of UC was defined as the use of either no pad or an occasional security pad at 6 months after RARP. Results: One hundred forty-four of the 200 patients (72.0%) achieved midterm recovery of UC and the median BNA was 70°. There were no significant differences in several parameters, including age, body mass index, total prostate volume, preservation of the neurovascular bundle, and postoperative membranous urethral length (MUL), between patients with BNA ≥70° and <70°. Of these parameters, only the BNA and postoperative MUL were independently associated with the midterm recovery of UC. The optimal cutoff points of the BNA and MUL (65° and 9 mm, respectively) were calculated by the receiver operating characteristics curve, and a scoring model for the prediction of midterm recovery of UC was developed according to the logistic regression analysis. This scoring model was demonstrated to be satisfactorily calibrated (p for Hosmer-Lemeshow test = 0.49) and provide good discrimination (area under the curve: 0.723; p < 0.001). Conclusions: These findings suggest that midterm recovery of UC after RARP is favorably affected by the large BNA and long postoperative MUL, and our scoring model can be used as a reliable tool for predicting the midterm continence status after RARP.

Abstract
BACKGROUND Enlarged median lobes (ML) can be technically challenging, particularly during bladder-neck dissection, and may affect urinary functional outcomes of robotic radical prostatectomy (RARP). If known, the impact of potentially larger bladder necks on continence and chronic obstruction on postoperative urinary symptoms might aid patient counseling. We assessed the impact of intraoperatively identified median lobes (ML) on urinary function. METHODS We reviewed our prospective RP database from 2013 to 2020. AUA symptoms scores (AUA-SS) were assessed preoperatively and at 1, 3, and 6 months. We compared patients with and without ML (NoML). Bladder-neck sparing was routine to avoid reconstruction. RESULTS Of 663 patients who completed AUA-SS questionnaires at all time points, 202 (30%) had ML. There were no significant differences in demographics, PSA, or clinical stage. Only two patients in ML and one in NoML group required bladder-neck reconstruction (1.2% and 0.2%). There was no immediate or long-term difference in continence rates between groups. Baseline mean AUA-SS was higher in ML patients and showed more improvement postoperatively (-5.5 vs. -3.6, p < .05) with greatest improvement in ML patients with severe preoperative symptoms (-15.1). There was no difference in AUA-SS between groups by 6 months. CONCLUSIONS The presence of enlarged ML does not increase the risk of incontinence after RARP and it appears that ML patients have greater improvements in postsurgical urinary functions. Preoperative diagnosis of ML and lower urinary tract symptoms assessment could be helpful in counseling patients undergoing RARP regarding their expected postoperative urinary outcomes.

Abstract
Introduction No standard definition for urinary continence after radical prostatectomy exists, and there are discrepancies in continence rates reported in the literature, as well as rates reported by physicians and patients. Therefore, we used two tools, a validated questionnaire and daily pad use, to identify the criteria that best reflects patients’ perceptions of continence recovery. Material and methods This is a prospective study of 74 patients who underwent nerve-sparing laparoscopic radical prostatectomy. Continence was assessed monthly for 3 months following catheter removal using the International Consultation on Incontinence Questionnaire Short Form (ICIQ-UI SF) and by recording the number of pads the patients used on a daily basis. According to daily pad use, patients were categorized as either dry (no-pads), socially continent (0–1 pad) or incontinent (≥2 pads). Results Seventy-four patients were enrolled with a mean age of 64.3 (±5.6) years. There were no significant differences in continence rates using scores from the International Consultation on Incontinence Questionnaire- Short Form (ICIQ-UI SF) or no-pad use (29.7% vs 32.4%, 45.9% vs 48.6% and 54.1% vs. 54.1%, at the 1-, 2- and 3-month follow-ups, respectively). However, the number of socially continent patients was significantly higher (59.5%, 70.3% and 81.1%, at the 1-, 2- and 3-month follow-ups, respectively [p <0.001]). Conclusions The totally dry definition better reflected patients’ perceptions rather than the socially continent definition for the evaluation of continence recovery following laparoscopic radical prostatectomy. To avoid discrepancies, we recommend the use of a validated questionnaire as well as the no-pad definition to standardize the reporting of post radical prostatectomy continence rates.

Abstract
AIMS AND OBJECTIVES To identify, appraise and summarise the available evidence relating to community nurses' attitudes, knowledge and educational needs in relation to urinary continence. BACKGROUND Community nurses play a pivotal role in identifying and supporting individuals who experience urinary continence issues. Gaps in nurses' continence-related education and knowledge may contribute to sub-optimal assessment and management across the continuum of care. DESIGN A systematic review. METHODS MEDLINE, CINAHL Complete and EMBASE were searched from inception to November 2020; keywords used included community nurses, urinary continence, incontinence, knowledge, attitude and education needs. Given the degree of heterogeneity between included studies, a meta-analysis was not feasible. Included studies were critically evaluated; key study characteristics and findings pertinent to the review purpose were summarised. The review adhered to the PRISMA 2020 checklist. RESULTS Four studies reported in six papers were included. Community nurses lacked knowledge in certain areas of urinary continence and incontinence. Nurses reported they were adequately prepared but without sufficient knowledge to effectively care for those with urinary incontinence. Community nurses' attitudes to urinary incontinence were generally positive, but they demonstrated misconceptions that urinary incontinence was inevitable and less distressing for older people. CONCLUSIONS There is limited research exploring community nurses' knowledge, attitudes and education needs in relation to urinary continence and incontinence care. Community nurses may have knowledge gaps and less favourable attitudes to some aspects of urinary continence care.

Abstract
OBJECTIVES To assess the effects of Retzius-sparing (RS) robotic-assisted laparoscopic prostatectomy (RALP) compared to standard RALP for the treatment of clinically localized prostate cancer. METHODS We performed a systematic search of multiple databases and the grey literature with no restrictions on the language of publication or publication status, up until June 2020. We included randomized controlled trials (RCTs) comparing RS-RALP with standard RALP. We performed a meta-analysis using a random-effect model. The quality of evidence was assessed on an outcome basis according to the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach. RESULTS Our search identified six records of five unique RCTs, of which two were published studies, one was in press, and two were abstract proceedings. There were 571 randomized participants, of whom 502 completed the trials. The mean age of participants was 64.6 years and the mean prostate-specific antigen level was 6.9 ng/mL. Approximately 54.2% of participants had cT1c disease, 38.6% had cT2a-b disease, and 7.1% had cT2c disease. RS-RALP probably improves continence within 1 week after catheter removal (risk ratio [RR] 1.74, 95% confidence interval [CI] 1.41-2.14; I2 = 0%; studies = 4; participants = 410; moderate-certainty evidence). Assuming 335 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 248 more men per 1000 (137 more to 382 more) reporting continence recovery. RS-RALP may increase continence at 3 months after surgery compared to standard RALP (RR 1.33, 95% CI 1.06-1.68; I2 = 86%; studies = 5; participants = 526; low-certainty evidence). Assuming 750 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 224 more men per 1000 (41 more to 462 more) reporting continence recovery. We are very uncertain about the effects of RS-RALP on serious adverse events compared to standard RALP (RR 1.40, 95% CI 0.47-4.17; studies = 2; participants = 230; very low-certainty evidence). CONCLUSIONS The findings of this review indicate that RS-RALP may result in better continence outcomes than standard RALP up to 6 months after surgery. Continence outcomes at 12 months may be similar. The disadvantages of RS-RALP may be higher positive surgical margin rates. We are very uncertain about the effect on biochemical recurrence-free survival and potency outcomes. Longer-term oncological and functional outcomes are lacking, and no preplanned subgroup analyses could be performed to explore the observed heterogeneity. Surgeons should discuss these trade-offs and the limitations of the evidence with their patients when considering this approach.

Abstract
OBJECTIVE Sparing of puboprostatic ligaments (PPLs) during radical prostatectomy was introduced as a technique to improve urinary continence. This study aims to study the effect of sparing of PPLs during laparoscopic radical prostatectomy in terms of continence during the first 3 months. METHODS A total of 74 patients, diagnosed with clinically localized prostate cancer, were randomly assigned to two equal groups; PPLs division and sparing during LRP. Based on the number of daily used pads, both groups completed 3 months follow-up to assess continence recovery. The effects of age, preoperative total prostate-specific antigen (PSA) and clinical tumor stage on continence recovery were also studied. The study was registered and approved by the Ethics Committee of Alexandria University-Faculty of Medicine (Protocol No. 0201074). RESULTS Seventy-four patients were enrolled, with a mean age of 63.8 years. Baseline characteristics were comparable, except significantly higher mean PSA in the division group. Sixty patients were continent (0-1 pad/day) at 3 months follow-up. Continence was significantly better in the sparing than division group at 1 week after catheter removal (67.6% vs 40.5%, p = 0.01), at 1 month (73% vs 45.9%, p = 0.009) and 2 months (89.2% vs 51.4%, p = 0.0001). At 3 months follow-up, there was no significant difference between both groups (83.3% vs 78.4% for sparing and division groups, respectively; p = 0.28). Moreover, continence was significantly improved at 3 months compared to 1 week in both groups. CONCLUSION Sparing of puboprostatic ligaments during radical prostatectomy significantly improves postoperative early recovery of urinary continence.

Abstract
OBJECTIVES To assess whether bladder neck angle and position on cystogram predict early urinary continence in patients scheduled for early catheter removal after radical prostatectomy (RP). METHODS A total of 103 patients undergoing open or robot-assisted RP by one expert surgeon between January and December 2019 were retrospectively analyzed. A cystogram was performed on postoperative day 3 or 4 to evaluate anastomotic leakage, and, if none or minimal, the catheter was removed. Urinary continence was evaluated with a validated questionnaire at 1 week, 1 month, and 3 months after RP. Four investigators of different experience assigned bladder neck angle and relative position of bladder neck to pubic symphysis on archived cystogram images. Association between these two parameters and urinary continence rates at different follow-up times was assessed with logistic regression analysis adjusting for patient and tumor characteristics, and surgical technique. Interobserver agreement in assigning the two parameters was measured with k statistic. RESULTS Catheter was removed immediately after cystogram in 101 (98%) patients. On multivariable analysis, only relative position of bladder neck to pubic symphysis was an independent predictor of 1-week (odds ratio [OR] 30. 95% confidence intervals [CIs] 6-138, p < 0.001), 1-month (OR 11. 95%CIs 3.8-32, p < 0.001), and 3-month (OR 19. 95%CIs 3.6-98, p < 0.001) urinary continence. Interobserver agreement for bladder neck and relative position of bladder neck to pubic symphysis was fair to moderate, and substantial to almost perfect, respectively. CONCLUSIONS Relative position of bladder neck to pubic symphysis on cystogram is a strong and reproducible predictor of early urinary continence after RP.

Abstract
Introduction: Cloaca malformation repair strategy is strongly dictated by common channel and urethral lengths. Mid to long common channel cloacas are challenging and often require laparotomy for dissection of pelvic structures. The balance of common channel and urethral lengths often dictates the approach for reconstruction. Laparoscopy has been utilized for rectal dissection but not for management of the urogenital (UG) structures. We hypothesized that laparoscopy could be applied to UG separation in reconstruction of cloaca malformations. Methods: Records were reviewed for 9 children with cloaca who underwent laparoscopic rectal mobilization and UG separation. Clinical parameters reviewed included demographics, relevant anatomic lengths, operative duration, transfusion requirements, and perioperative complications. Results: Repair was perfomed at a median (interquartile range) age of 12 (7, 15) months. Common channel length as measured by cystoscopy was 3.5 (3.3, 4.5) cm. There were no intraoperative complications. Transfusion requirements were minimal. Postoperative length of stay was 6 (5, 11) days. One patient developed a urethral web and 2 developed vaginal stenosis. One patient later underwent a laparotomy for obstruction due to a twisted rectal pull-through. Conclusions: Laparoscopic rectal mobilization and UG separation in long common channel cloaca are safe and well tolerated. Laparoscopy affords full evaluation of Mullerian structures and enables separation of the common UG wall, which may ultimately enhance long-term urinary continence.

Abstract
BACKGROUND To compare the outcomes of bidirectional barbed suture and continuous poliglecaprone suture for urethrovesical anastomosis (UVA) during laparoscopic radical prostatectomy (LRP). METHODS Single-needle poliglecaprone suture was used for UVA in Group 1 (n=27), and double-needle bidirectional barbed suture was used for UVA (n=27) in Group 2. Age, body mass index (BMI), prostate-specific antigen (PSA) level, prostate volume, operative time, anastomosis time, estimated blood loss, Gleason score, number of hospitalization days, and urinary continence at postoperative month 1, 3, 6, and 12 were analyzed statistically. RESULTS There were no significant differences in age, BMI, prostate volume, PSA level, Gleason score, and indwelling catheter time between the two groups. However, bidirectional barbed suture was associated with a significantly shorter anastomosis time (P=0.007), operation time (P=0.008) and hospitalization duration (P<0.001), and a significantly lower blood loss volume (P=0.005). At the first-month follow-up, urinary continence was achieved in 5 (19%) and 15 (56%) patients in Group 1 and 2, respectively (P=0.005); postoperative third month: 11 (41%) and 23 (85%) patients in Group 1 and 2 respectively (P=0.001); postoperative sixth month: 21 (78%) and 25 (93%) patients in Group 1 and 2 respectively (P=0.250); postoperative first year: 25 (93%) and 27 (100%) patients in Group 1 and 2 respectively (P=0.471). Multivariate regression analysis showed that anastomosis time (HR =0.636; P<0.001) was an independent predictor of postoperative continence. CONCLUSIONS The current findings show that bidirectional barbed suture for UVA during LRP can shorten UVA time and provide better outcomes in terms of early urinary continence recovery.

Abstract
OBJECTIVE To evaluate the impact of Retzius-sparing robot-assisted radical prostatectomy (posterior approach) on early recovery of urinary continence (UC) compared to the conventional approach (anterior approach) for the treatment of clinically localized prostate cancer (PCa). METHODS A total of 110 consecutive patients with clinically localized PCa were prospectively randomized in a 1:1 ratio to an anterior group (n = 55) or a posterior group (n = 55). The primary outcome was immediate UC, defined as freedom from any pad use within 1 week after removal of the urinary catheter. The UC rate following surgery was also calculated with Kaplan-Meier curves, and the log-rank test was used for statistical comparison. Intra-operative outcomes, pathological data and oncological outcomes, including positive surgical margin (PSM) status and biochemical recurrence-free survival (BCRFS), were also compared between the two groups. The comparison of the two approaches was also analysed in subgroups after risk stratification. RESULTS Of the patients who underwent the posterior approach, 69.1% achieved immediate UC compared with 30.9% in the anterior group (relative risk 2.24, 95% confidence interval [CI] 1.48-3.51; P = 0.000). The relative Kaplan-Meier curves for UC during the 12-month follow-up revealed statistically better recovery in the posterior group when compared with the anterior group (hazard ratio [HR] 1.51, 95% CI 1.01-2.24; log-rank P = 0.007). No statistically significant differences were observed between the groups regarding complications (P = 0.399), PSM status (P = 0.225) or BCRFS (HR 4.80, 95% CI 0.97-23.78; log-rank P = 0.111). In sub-analyses, no significant difference between the two approaches with regard to UC recovery in patients with high-risk PCa was observed (HR 1.26, 95% CI 0.63-2.51; log-rank P = 0.415). CONCLUSIONS The Retzius-sparing approach significantly improved early recovery of UC compared to the conventional approach. Further prospective studies are needed to confirm the benefits of the Retzius-sparing approach for clinically localized PCa, especially for high-risk cases.

Abstract
OBJECTIVES To describe in detail the techniques for transvesical robot-assisted radical prostatectomy (RARP) using the da Vinci Si/Xi system (Intuitive Surgical, Sunnyvale, CA, USA) and to evaluate functional and oncological outcomes in 35 patients with prostate cancer. PATIENTS AND METHODS Thirty-five patients with localized prostate cancer were enrolled for transvesical RARP. The patients' preoperative data (mean ± sd age 63.4 ± 8.1 years, body mass index 28.6 ± 5.3 kg/m2 , total prostate-specific antigen 10.8 ± 4.9 ng/mL and prostate volume 30.6 ± 14.4 mL, and median [interquartile range {IQR}] biopsy Gleason score 6 [6-7], and International Index of Erectile Function [IIEF]-5 score 18 [16-20]) were collected. Preoperative assessment revealed 28 cases of cT2a and seven cases of cT2b disease. All patients were continent preoperatively (defined as no pad required or one dry pad per day as a precaution). Surgical results and peri-operative complications were assessed. All patients were followed up for at least 12 months postoperatively. RESULTS The mean operating time was 150 ± 35 min. Estimated blood loss was 100 ± 45 mL. Urinary infection was noted in one patient and managed with levofloxacin. Another patient complained of nocturia on postoperative day 14, which was relieved with solifenacin succinate. Urethral catheters were removed on postoperative day 7. Thirty-two patients achieved immediate urinary continence, with three patients returning to full continence on postoperative day 14. Postoperative pathology confirmed 24 pT2a cases, nine pT2b cases and two pT2c cases (median [IQR] Gleason score 6 [6-7]). Positive surgical margins were found in four patients (11.4%). No urethral stricture or urinary leakage was noted on urethrocystography taken 3 months after surgery. Urodynamic studies were performed preoperatively and 6 months after surgery: median (IQR) maximum urinary flow 12.2 (10.2-14.9) vs 13.7 (10.1-15.0) mL/s; bladder capacity 385.3 (351.3-410.2) vs 370.2 (330.1-395.4) mL; and voiding phase detrusor contractility 38.5 (27.8-42.3) vs 35.6 (28.3-41.3) mmH2 O, respectively. During a minimum of 12 months of follow-up, no biochemical recurrence was noted in any patient. The median (IQR) IIEF-5 score was 17 (16-19). CONCLUSIONS The transvesical approach is a valid alternative to RARP in selected patients, providing promising postoperative urinary continence. Long-term functional and oncological results require further investigation.

Abstract
The traditional transurethral resection of the prostate (TURP) is considered as gold-standard surgical treatment to relieve symptoms resulting from bladder outlet obstruction by prostate enlargement. However, with the advances of novel laser technologies and more experienced surgeon conquering the steep learning curve, anatomical endoscopic enucleation of prostate (AEEP) has become a more popular alternative surgical technique. Although AEEP has compatible functional outcome, less blood loss, shorter catheterisation duration and hospital stay, the risk of post-operative urinary incontinence (UI) is often an issue of concern. In this review, we focus on discussion about risk factors related to increased incidence of UI, some surgical tips to avoid damaging external urinary sphincter and treatment strategies to facilitate recovery of urinary continence after surgery.

Abstract
Objectives To describe our surgical technique of “muscle‐sparing” laparoscopic radical prostatectomy and to review relevant anatomical landmarks during the procedure. Methods This was a prospective non‐controlled case series of 120 consecutive patients who underwent laparoscopic radical prostatectomy, always carried out by the same surgeon (OL). The median follow‐up period was 33 months. Dissection of the puboperinealis and puborectalis muscle consists of the precise dissection of the puborectalis and puboperinealis muscles from the periprostatic fascia. Rhabdomyo‐dissection consists of an approach that spares the external urethral sphincter from the ventral surface of the prostate and membranous urethra. Clinical data were collected in a dedicated database. Intraoperative variables, postoperative complications and outcomes of urinary continence were assessed. A descriptive statistical analysis was carried out. Results Continence rates were 70.8%, 83.3% and 92.5%, at 0–2, 3–4 and 5–8 weeks after removal of the urethral catheter, respectively; 96.6% and 98.3% at 6 and 12 months after surgery. The positive surgical margin rate associated with rhabdomyo‐dissection was 8.3%. Conclusions Laparoscopic radical prostatectomy with dissection of the puboperinealis and puborectalis muscle, and rhabdomyo‐dissection is an oncologically safe procedure, associated with very early recovery urinary continence in most patients. It is a technique that can be applied in most cases, as long as there is no invasion of the ventral side of the prostate.

Abstract
AIMS To evaluate the reliability of different methods to normalize pelvic floor muscles (PFM) electromyography (EMG). METHODS Thirty nulliparous women (23.9 ± 3.2 years), free from PFM dysfunction, completed two test sessions 7 days apart. For EMG normalization, signals were acquired during four different tasks using a vaginal probe in situ: PFM maximal voluntary contraction (MVC) and three daily activities with increased intra-abdominal pressure (coughing, Valsalva maneuver, and abdominal contraction). The intraclass correlation coefficients (ICC), standard error of measurement (SEM), relative standard error of measurement (%SEM), and minimal detectable change (MDC) were calculated for each variable. RESULTS ICC values for test-retest reliability of normalization methods ranged from 0.61 to 0.95. The highest values were obtained for mean root mean square (RMS) of the abdominal contraction and peak RMS of PFM-MVC. Normalization using RMS of PFM-MVC showed the lowest values of SEM and MDC. CONCLUSIONS The normalization of EMG data is considered a fundamental part of EMG investigations. These findings suggest that the normalization of PFM-EMG by either peak RMS of PFM-MVC or mean and peak RMS of abdominal contraction has excellent reliability and it can be applied in studies involving the evaluation of young women.

Abstract
Urethral smooth muscle (USM) generates tone to prevent urine leakage from the bladder during filling. USM tone has been thought to be a voltage-dependent process, relying on Ca2+ influx via voltage-dependent Ca2+ channels in USM cells, modulated by the activation of Ca2+-activated Cl- channels encoded by Ano1. However, recent findings in the mouse have suggested that USM tone is voltage independent, relying on Ca2+ influx through Orai channels via store-operated Ca2+ entry (SOCE). We explored if this pathway also occurred in the pig using isometric tension recordings of USM tone. Pig USM strips generated myogenic tone, which was nearly abolished by the Cav1.2 channel antagonist nifedipine and the ATP-dependent K+ channel agonist pinacidil. Pig USM tone was reduced by the Orai channel blocker GSK-7975A. Electrical field stimulation (EFS) led to phentolamine-sensitive contractions of USM strips. Contractions of pig USM were also induced by phenylephrine. Phenylephrine-evoked and EFS-evoked contractions of pig USM were reduced by ~50-75% by nifedipine and ~30% by GSK-7975A. Inhibition of Ano1 channels had no effect on tone or EFS-evoked contractions of pig USM. In conclusion, unlike the mouse, pig USM exhibited voltage-dependent tone and agonist/EFS-evoked contractions. Whereas SOCE plays a role in generating tone and agonist/neural-evoked contractions in both species, this dominates in the mouse. Tone and agonist/EFS-evoked contractions of pig USM are the result of Ca2+ influx primarily through Cav1.2 channels, and no evidence was found supporting a role of Ano1 channels in modulating these mechanisms.

Abstract
This study aimed to evaluate the effect of bladder neck preservation (BNP) on long-term urinary continence after robot-assisted laparoscopic prostatectomy (RALP). We systematically searched the PubMed, Embase, and Cochrane Library databases to identify studies that assessed the difference in urinary continence and oncologic outcomes between patients who underwent RALP with BNP and those who underwent RALP without BNP. Four trials (1880 cases with BNP, 727 controls without BNP) were considered suitable for meta-analysis. BNP was associated with significantly better urinary continence outcomes at 3–4 months (odds ratio (OR), 2.88; 95% confidence interval (CI), 1.52–5.48; p = 0.001), 12 months (OR, 2.03; 95% CI, 1.10–3.74; p = 0.02), and 24 months (OR, 3.23; 95% CI, 1.13–9.20; p = 0.03) after RALP. There was no difference in the rate of overall positive surgical margin (PSM) (OR, 1.00; 95% CI, 0.72–1.39; p = 0.99) and that of PSM at the prostate base (OR, 0.49; 95% CI, 0.21–1.13; p = 0.09) between the two groups. The BNP technique during RALP leads to early return of urinary continence and long-term urinary continence without compromising the oncologic outcomes.

Abstract
Introduction Nowadays, the expectations for functional prostatectomy outcomes are quite high. Robot-assisted laparoscopic radical prostatectomy (RALRP) has become an increasingly common treatment option for men with localized prostate cancer. In this study, we aimed to present the results of our bilateral nerve-sparing RALRP procedure and to evaluate the effects of the learning curve (LC) on perioperative data, early oncologic, and functional outcomes. Methods The records of 132 RALRP cases performed between January 2016 and March 2019 by a single surgeon experienced in open and laparoscopic radical prostatectomy were evaluated retrospectively. Results of 91 cases with the bilateral nerve-sparing technique were analyzed. The learning curve was determined using the moving average method. LC analysis using the moving average method showed that the LC stabilized between cases 40 and 50. So, patients were divided into two groups: group 1 consisted of the first 45 cases, while group 2 consisted of 46-91st cases. The groups were compared in terms of surgical, functional, and oncologic outcomes. Results The mean duration of surgery was significantly reduced in the second group (250 vs 235 min, p <0.002). However, there was no statistically significant difference between the groups in terms of hemoglobin decrease, hospitalization and catheterization time, and intraoperative and postoperative complication rates. The rates of pT2 cancers’ positive surgical margins (PSMs) were 32.4% and 19.4%, respectively. The recovery rate of continence in all the patients was 90.1% at 12 months. The potency ratios were calculated as 33.8% at 12 months. There was no statistically significant difference between the groups in terms of potency and continence rates at 3 months and 12 months, postoperatively. Conclusion For surgeons experienced in retropubic radical prostatectomy (RRP) and laparoscopic radical prostatectomy (LRP) surgeries, RALRP is a safe and feasible surgical procedure for both oncological and functional outcomes even during the learning curve.

Abstract
PURPOSE Urinary incontinence after prostate treatment (IPT) is one of the few urologic diseases that is iatrogenic, and, therefore, predictable and perhaps preventable. Evaluation of the incontinent patient, risk factors for IPT, the assessment of the patient prior to intervention, and a stepwise approach to management are covered in this guideline. Algorithms for patient evaluation, surgical management, and device failure are also provided. MATERIALS AND METHODS This guideline was developed using a systematic review from the Mayo Clinic Evidence Based Practice Center with additional supplementation by the authors. A research librarian conducted searches from 2000 to December 21st, 2017 using Ovid, MEDLINE, Cochrane Central Register of Controlled Trials, and Cochrane Databases of Systematic Reviews. Additional references through 12/31/2018 were identified. RESULTS This guideline was developed by a multi-disciplinary panel to inform clinicians on the proper assessment of patients with IPT and the safe and effective management of the condition in both surgical and non-surgical contexts. Statements guiding the clinician on proper management of device failure are also included. CONCLUSION Most patients who undergo radical prostatectomy (RP), and some patients who undergo radiation therapy (RT) or surgery for benign prostatic hyperplasia (BPH), will experience IPT. Although non-surgical options, such as pelvic floor muscle exercises (PFME), can hasten continence recovery, patients who remain incontinent at one-year post-procedure, or have severe incontinence at six months, may elect to undergo surgical treatment (e.g. artificial urinary sphincter). Prior to IPT surgery, the risks, benefits, alternatives, and additional likely procedures should be discussed with the patient.

Abstract
INTRODUCTION Diffuse or massive tumors involving the perineal and pelvic compartments may require aggressive surgical treatment in children. The authors, propose and present their results using a Posterior Sagittal Anorectal Mobilization (PSAM) METHODS: The oncologic patient is placed in a prone position with the pelvis elevated, without a previous colostomy. A 10 Ch bladder catheter is positioned. A midline sagittal incision is performed from the coccyx to the posterior margin of the anus. Fine electrocautery is used to obtain an accurate dissection all around the anal margin itself. The incisional so involves the midline dissection into the perineal body. Reconstruction is achieved by the classical pelvic-perineal anatomical structure approximation. RESULTS The authors describe for the first time a novel posterior anorectal mobilization technique for four children with pelvic-perineal tumors. No intraoperative or post-operative complications occurred. The oldest boy presented at follow-up a complete normal faecal and urinary continence (Krickenbeck criteria). CONCLUSION The presented technical approach, defined as PSAM, is completely suitable for surgical resection of perineal-pelvic tumors, without the need of more invasive operations including transpubic dissection and/or anorectal split. Moreover, nervous and muscular sphincter structures are easily identified and preserved.

Abstract
KEY POINTS Contraction of urethral smooth muscle cells (USMCs) contributes to urinary continence. Ca2+ signalling in USMCs was investigated in intact urethral muscles using a genetically encoded Ca2+ sensor, GCaMP3, expressed selectively in USMCs. USMCs were spontaneously active in situ, firing intracellular Ca2+ waves that were asynchronous at different sites within cells and between adjacent cells. Spontaneous Ca2+ waves in USMCs were myogenic but enhanced by adrenergic or purinergic agonists and decreased by nitric oxide. Ca2+ waves arose from inositol trisphosphate type 1 receptors and ryanodine receptors, and Ca2+ influx by store-operated calcium entry was required to maintain Ca2+ release events. Ca2+ release and development of Ca2+ waves appear to be the primary source of Ca2+ for excitation-contraction coupling in the mouse urethra, and no evidence was found that voltage-dependent Ca2+ entry via L-type or T-type channels was required for responses to α adrenergic responses. ABSTRACT Urethral smooth muscle cells (USMCs) generate myogenic tone and contribute to urinary continence. Currently, little is known about Ca2+ signalling in USMCs in situ, and therefore little is known about the source(s) of Ca2+ required for excitation-contraction coupling. We characterized Ca2+ signalling in USMCs within intact urethral muscles using a genetically encoded Ca2+ sensor, GCaMP3, expressed selectively in USMCs. USMCs fired spontaneous intracellular Ca2+ waves that did not propagate cell-to-cell across muscle bundles. Ca2+ waves increased dramatically in response to the α1 adrenoceptor agonist phenylephrine (10 μm) and to ATP (10 μm). Ca2+ waves were inhibited by the nitric oxide donor DEA NONOate (10 μm). Ca2+ influx and release from sarcoplasmic reticulum stores contributed to Ca2+ waves, as Ca2+ free bathing solution and blocking the sarcoplasmic Ca2+ -ATPase abolished activity. Intracellular Ca2+ release involved cooperation between ryanadine receptors and inositol trisphosphate receptors, as tetracaine and ryanodine (100 μm) and xestospongin C (1 μm) reduced Ca2+ waves. Ca2+ waves were insensitive to L-type Ca2+ channel modulators nifedipine (1 μm), nicardipine (1 μm), isradipine (1 μm) and FPL 64176 (1 μm), and were unaffected by the T-type Ca2+ channel antagonists NNC-550396 (1 μm) and TTA-A2 (1 μm). Ca2+ waves were reduced by the store operated Ca2+ entry blocker SKF 96365 (10 μm) and by an Orai antagonist, GSK-7975A (1 μm). The latter also reduced urethral contractions induced by phenylephrine, suggesting that Orai can function effectively as a receptor-operated channel. In conclusion, Ca2+ waves in mouse USMCs are a source of Ca2+ for excitation-contraction coupling in urethral muscles.

Abstract
Urge Urinary Incontinence: “a sudden and uncontrollable desire to void which is impossible to defer” is extremely common and considered the most bothersome of lower urinary tract conditions. Current treatments rely on pharmacological, neuromodulatory, and neurotoxicological approaches to manage the disorder, by reducing the excitability of the bladder muscle. However, some patients remain refractory to treatment. An alternative approach would be to temporarily suppress activity of the micturition control circuitry at the time of need i.e., urgency. In this study we investigated, in a rat model, the utility of high frequency pelvic nerve stimulation to produce a rapid onset, reversible suppression of voiding. In urethane-anesthetized rats periodic voiding was induced by continuous infusion of saline into the bladder whilst recording bladder pressure and electrical activity from the external urethral sphincter (EUS). High frequency (1–3 kHz), sinusoidal pelvic nerve stimulation initiated at the onset of the sharp rise in bladder pressure signaling an imminent void aborted the detrusor contraction. Urine output was suppressed and tone in the EUS increased. Stimulating the right or left nerve was equally effective. The effect was rapid in onset, reversible, and reproducible and evoked only minimal “off target” side effects on blood pressure, heart rate, respiration, uterine pressure, or rectal pressure. Transient contraction of abdominal wall was observed in some animals. Stimulation applied during the filling phase evoked a small, transient rise in bladder pressure and increased tonic activity in the EUS, but no urine output. Suppression of micturition persisted after section of the contralateral pelvic nerve or after ligation of the nerve distal to the electrode cuff on the ipsilateral side. We conclude that high frequency pelvic nerve stimulation initiated at the onset of an imminent void provides a potential means to control urinary continence.

Abstract
In an editorial board-moderated debate format, two experts in prostate cancer surgery are challenged with presenting the key strategies in radical prostatectomy that improve urinary functional outcomes. Dr Bernardo Rocco was tasked with arguing the facts that support the anatomical preservation and reconstruction steps that improve urinary continence. Drs Christian Pavlovich and Sasha Druskin were tasked with arguing the facts supporting neurovascular bundle and high anterior release surgical planes that improve urinary continence. Associate Editor John Davis moderates the debate, and outlines the current status of validated patient questionnaires that can be used to evaluate urinary continence, and recent work that allows measuring what constitutes a 'clinically significant' difference that either or both of these surgical techniques could influence. A review of raw data from a publication from Dr Pavlovich's team demonstrates how clinically relevant differences in patient-reported outcomes can be correlated to technique. A visual atlas is presented from both presenting teams, and Dr Davis demonstrates further reproducibility of technique. A linked video on this concept is available as a supplementary file.

Abstract
INTRODUCTION Erectile dysfunction (ED) and urinary incontinence (UI) following radical prostatectomy (RP) adversely impact patients psycho-emotional status reducing the quality of life and treatment satisfaction. AIM To investigate the rates of regaining continence and erectile function (EF) after nerve-sparing radical retropubic prostatectomy (NS-RRP) and nerve-sparing laparoscopic radical prostatectomy (NS-LRP) in the early postoperative period. MATERIALS AND METHODS The study comprised 116 patients who preserved sexual activity and the ability to have sex. 64 patients underwent standard resection of NVB (34 RRP and 30 LRP) and in 52 patients the NVB resection was performed using a waterjet dissector (WD) (30 RRP and 22 LRP). All operations were performed by one surgeon with the experience of over 350 RRP and 150 LRP. The study patients had low and moderate risk prostate cancer, according to DAmico risk classification. RESULTS Our study findings showed that patients who underwent the WD of NVB had significantly greater IIEF-5 scores (by 2.8 scores) at 8 weeks than after the standard NS-RP. After 6 month follow-up the scores increased by 3.5 points. Patients who underwent NS-RP + WD achieved a successful sexual intercourse 3 months after surgery (regardless of the use of PDE5 inhibitors). In the group of patients who underwent standard NS-RP, it took a longer time to achieve a successful sexual intercourse. Sixty-seven percent of patients who underwent NS-RP + WD were fully continent at one month follow-up after removal of urethral catheter, while most patients treated with standard NS-RP (41%) had mild stress UI. After 3 months follow-up, among patients who underwent NS-RP + WD only one patient had mild stress UI and the vast majority (95%) of patients were fully continent. At 6 months after removal of the urethral catheter there were no significant differences between the groups in regaining urinary continence. CONCLUSIONS Waterjet dissection of NVB significantly improves patients postoperative quality of life due to early recovery of urinary continence and EF.

Abstract
PURPOSE To determine anatomic and functional properties of the bulboglandularis muscle (Bgm) for clarifying its role in micturition in female rabbits. MATERIAL AND METHODS Virgin female rabbits were used to describe the gross anatomy and innervation of the Bgm, to determine the effect of the Bgm contraction on urethral pressure, and to evaluate the Bgm activity during the induced-micturition. Both electromyogram and cystometrogram activity were simultaneously recorded in urethane-anesthetized rabbits. Bladder function was assessed measuring standard urodynamic variables before and after blocking the Bgm activity for approaching its contribution to micturition. The relevance of the Bgm activation for micturition was approached applying lidocaine injections. RESULTS The Bgm was composed of circularly oriented striated fibers enveloping distal urethra and pelvic vagina. Both the venous plexus and urethra were comprised by the Bgm contraction induced by electrical stimulation. The Bgm showed bursts of tonic activity at the storage phase of micturition that gradually decreased until turning off as the onset of the voiding phase. The voided volume, the voiding efficiency, the threshold pressure, and the maximal pressure were decreased after lidocaine injection. Contrastingly, the threshold volume, the residual volume, the voiding duration, and the urethral resistance at voiding were increased. CONCLUSIONS Present anatomical and physiological findings support that the Bgm acts as a sphincter during micturition of female rabbits. Neurourol.

Abstract
Introduction To analyze the correlations of bladder management technique, ambulatory status and urologic reconstruction on quality of life (QOL) as affected by urinary symptoms in adult spina bifida (SB) patients. Material and methods Sixty–six adult SB patients completed the RAND 36–Item Health Survey (mSF–36) and Incontinence Quality of Life (I–QOL). Demographic information, history of urinary reconstruction, and bladder management techniques were reviewed and analyzed with respect to survey scores. Results Mean age of patients was 32.3 (SD ±7.2) years and 44 patients (66.7%) were female. Forty–five patients (68.2%) were mainly ambulatory, 21 (31.8%) use a wheelchair and 10 (15.2%) had urologic reconstruction, while 56 (83.3%) did not. Twelve patients (18.2%) void, 42 (63.6%) perform clean intermittent catheterization (CIC), 4 (6.1%) use an indwelling catheter, 3 (4.5%) have an ileal conduit (IC) and 5 (7.6%) mainly use diapers. Mean mSF–36 General Health score was 56.5 (SD ±22.9) and mean I–QOL Sum score was 50.9 (SD ±21.7), where lower scores reflect lower QOL. mSF–36 and I–QOL scores did not significantly correlate with bladder management technique, ambulatory status or urologic reconstruction. A correlation was noted between I–QOL scales and most mSF–36 scales (all p <0.02). Conclusions In our cohort study of adult SB patients, bladder management technique and urologic reconstruction did not correlate with urinary (I–QOL) or general health (mSF–36) domains, although I–QOL and mSF–36 scores correlated closely, suggesting urinary continence is significantly related to general QOL. However, we are unable to identify a single factor that improves either urinary or general QOL.

Abstract
AIMS To investigate the functional outcome after supratrigonal cystectomy and augmentation ileocystoplasty in adult patients with refractory neurogenic lower urinary tract dysfunction (NLUTD). METHODS Retrospective follow-up investigation in a single spinal cord injury rehabilitation center. In 29 patients, urodynamic data before and after supratrigonal cystectomy and augmentation ileocystoplasty, clinical outcome and post-operative complications were evaluated. RESULTS The median age of the 29 patients at the time of surgery was 31 years, a median 14 years after NLUTD had occurred. At the last follow-up visit (median 2.4, range 0.4-9.0 years post-operatively), 20/29 patients (69%) were continent compared to 2/29 pre-operatively (P = 0.001). Furthermore, 16 patients required no or less detrusor relaxation therapy after augmentation ileocystoplasty. Augmentation cystoplasty resulted in a significant (P = 0.001) increase in the median bladder capacity (from 240 ml to 500 ml) and compliance (from 13 ml/cm H2 O to 50 ml/cm H2 O). The median maximum detrusor pressure had decreased significantly (P = 0.001) from 38 cm H2 O to 15 cm H2 O. Significantly (P = 0.001) fewer patients presented with a risk for renal damage (1 vs. 15 with maximum detrusor pressure >40 cm H2 O and 1 vs. 12 with detrusor compliance <20 ml/cm H2 O) at the last follow-up. The following complications were observed in 11/29 (38%) patients: paralytic and obstructive ileus, impaired bowel function, bladder stones, dehiscence, metabolic acidosis and autonomic dysreflexia. CONCLUSIONS Protection of renal function, adequate bladder capacity and low detrusor pressure can be achieved using supratrigonal cystectomy and augmentation ileocystoplasty in patients suffering from refractory NLUTD.

Abstract
INTRODUCTION Preservation of the bladder neck (BN) has been controversial, as limited excision of the bladder neck may result in incomplete resection of the disease. Moreover, the urinary continence rate may not be improved. AIM To evaluate the effect of bladder neck sparing on urinary continence, and surgical margins status in prostate cancer (PCa) patients treated with laparoscopic radical extraperitoneal prostatectomy. MATERIAL AND METHODS A retrospective analysis of 295 consecutive patients who had undergone laparoscopic radical extraperitoneal prostatectomy for clinically localised prostate cancer in a single institution was performed. Positive surgical margin (SM(+)) and urinary continence status at 3, 6, and 12 months were evaluated. RESULTS The distribution of SM(+) for pT2, pT3, and pT4a was 15.3% (27/176), 49.1% (58/118), and 100% (1/1), respectively. Overall, there were 55.61%, 80.61%, and 84.69% of men continent at 3, 6, and 12 months, respectively. However, when limiting the analysis to those who did not receive adjuvant radiotherapy within 12 months following surgery, urinary continence rates were 59.23%, 85.86%, and 90.21% at 3, 6, and 12 months, respectively. Preoperative prostate-specific antigen (PSA) and pathological T stage were identified as significant predictors of positive surgical margins. CONCLUSIONS CONCLUSIONS Laparoscopic radical extraperitoneal prostatectomy with bladder neck preservation has been a safe procedure which has resulted in good functional outcome. We observed a relatively high incidence of positive surgical margins which could be attributed to a large number of extracapsular disease cases.

Abstract
BACKGROUND/AIM The Urological Clinic of the S. Orsola-Malpighi University Hospital, Bologna has been carrying out laparoscopic radical prostatectomy since 2002. In this study, we report the results after 10 years of LRP, analyzing in particular the oncological and functional aspects. PATIENTS AND METHODS Between March 2002 and August 2011, 400 patients underwent laparoscopic radical prostatectomy. Cancer control, recovery of continence and potency were evaluated at 1, 3, 6 and 12 months. All data were retrospectively collected on the basis of thorough clinical and pathological examination. RESULTS Follow-up ranged from 10 to 122 months. Pathological examination revealed pT2 and pT3 cancers in 63.5% and 36.5% of patients, respectively. The incidence of positive surgical margins and biochemical relapse rate was 33.8% and 12.0%, respectively. CONCLUSION 10 Years after the first laparoscopic radical prostatectomy was performed at our Center, we can state that it is a reliable alternative to traditional surgery, with satisfactory oncological and functional results.

Abstract
Coughing provokes stress urinary incontinence, and voluntary coughs are employed clinically to assess pelvic floor dysfunction. Understanding urethral dynamics during coughing in men is limited, and it is unclear whether voluntary coughs are an appropriate surrogate for spontaneous coughs. We aimed to investigate the dynamics of urethral motion in continent men during voluntary and evoked coughs. Thirteen men (28-42 years) with no history of urological disorders volunteered to participate. Transperineal ultrasound (US) images were recorded and synchronized with measures of intraabdominal pressure (IAP), airflow, and abdominal/chest wall electromyography during voluntary coughs and coughs evoked by inhalation of nebulized capsaicin. Temporal and spatial aspects of urethral movement induced by contraction of the striated urethral sphincter (SUS), levator ani (LA), and bulbocavernosus (BC) muscles and mechanical aspects of cough generation were investigated. Results showed coughing involved complex urethral dynamics. Urethral motion implied SUS and BC shortening and LA lengthening during preparatory and expulsion phases. Evoked coughs resulted in greater IAP, greater bladder base descent (LA lengthening), and greater midurethral displacement (SUS shortening). The preparatory inspiration cough phase was shorter during evoked coughs, as was the latency between onset of midurethral displacement and expulsion. Maximum midurethral displacement coincided with maximal bladder base descent during voluntary cough, but followed it during evoked cough. The data revealed complex interaction between muscles involved in continence in men. Spatial and temporal differences in urethral dynamics and cough mechanics between cough types suggest that voluntary coughing may not adequately assess capacity of the continence mechanism.
