Urinary incontinence is one of the main concerns for patients after radical prostatectomy. Differences in surgical experience among surgeons could partly explain the wide range of frequencies observed. Our aim was to evaluate the association between the surgeons' experience and center caseload with relation to urinary continence recovery after Retzius-sparing robot-assisted radical prostatectomy (RS-RARP). Prospective observational single-center study. Five surgeons consecutively operated 405 patients between July 2017 and February 2022. Continence recovery was evaluated with pad count and by employing the short form of the International Consultation on Incontinence Questionnaire (ICIQ-SF), pre- and postoperatively at 1 year. Non-parametric tests were used. Median age was 63 years, 30% of patients presented with local advanced disease; the positive surgical margin rate (over 3 mm length) was 16%. Complication rate was 1% (Clavien–Dindo > II). One year after surgery, continence was assessed in 282 patients, of whom 87% were pad free and 51% never leaked (ICIQ-SF = 0). With respect to the mean annual number of procedures per surgeon, divided in < 20, 20–39 and ≥ 40, pad-free rates were achieved in 93%, 85%, and 84% and absence of urine leak rates in 47%, 62% and 48% of patients, respectively. Postoperative median ICIQ-SF was five. We acknowledge the limitation of a 12-month follow-up and the fact that we are a medium-volume center. There is no statistically significant association between continence recovery, surgeon's experience and center caseload. Continence recovery at 1 year after surgery is adequate and robust to surgeon's experience. [ABSTRACT FROM AUTHOR]

Introduction: Robotic surgical performance, in particular suturing, has been linked to postoperative clinical outcomes. Before attempting live surgery, virtual reality (VR) simulators afford opportunities for training surgeons to learn fundamental technical skills. Herein, we evaluate the association of suturing technical skill assessments between VR simulation and live surgery, and functional clinical outcomes. Materials and Methods: Twenty surgeons completed a VR suturing exercise on the Mimic™ Flex VR simulator and the anterior vesicourethral anastomosis during robot-assisted radical prostatectomy (RARP). Three independent and blinded graders provided technical skill scores using a validated assessment tool. Correlations between VR and live scores were assessed by Spearman's correlation coefficients (ρ). In addition, 117 historic RARP cases from participating surgeons were extracted, and the association between VR technical skill scores and urinary continence recovery was assessed by a multilevel mixed-effects model. Results: A total of 20 (6 training and 14 expert) surgeons participated. Statistically significant correlations for scores provided between VR simulation and live surgery were found for overall and needle driving scores (ρ = 0.555, p = 0.011; ρ = 0.570, p = 0.009, respectively). A subanalysis performed on training surgeons found significant correlations for overall scores between VR simulation and live surgery (ρ = 0.828, p = 0.042). Expert cases with high VR needle driving scores had significantly greater continence recovery rates at 24 months after RARP (98.5% vs 84.9%, p = 0.028). Conclusions: Our study found significant correlations in technical scores between VR and live surgery, especially among training surgeons. In addition, we found that VR needle driving scores were associated with continence recovery after RARP. Our data support the association of skill assessments between VR simulation and live surgery and potential implications for clinical outcomes. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the recovery of early urinary continence in patients with prostate cancer using a suprapubic catheter during Retzius-sparing robotic-assistant laparoscopic prostatectomy. Patients and methods: From January 2018 to January 2019, 223 patients diagnosed with prostate cancer who underwent Retzius-sparing robotic-assistant laparoscopic prostatectomy in Diakonie Klinikum Stuttgart were involved in our study. From January 2018 to June 2018, patients (112 cases) only had an indwelling urinary catheter during Retzius-sparing robotic-assistant laparoscopic prostatectomy, while from July 2018 to January 2019, patients (111 cases) were offered an extra suprapubic catheter during operation. The recovery of early urinary continence of patients was mainly investigated one month later. Results: The overall early urinary continence rate was 81.61%. Patients with suprapubic catheter had better urinary control results, compared to patients with only indwelling urinary catheter (87.39% vs 75.89%, p = 0.027). In addition, International Prostate Symptom Score and irritative subscore in patients with good urinary control were significantly lower than that in patients with urinary incontinence. Suprapubic catheter insertion (OR 0.395; 95% CI 0.190–0.821) and advanced pathological tumor stage (T3a–T4) (OR 2.061; 95% CI 1.008–4.217) were two independent influencing factors for early urinary continence recovery in patients who underwent Retzius-sparing robotic-assistant laparoscopic prostatectomy through multivariate logistic regression analysis. Conclusion: Suprapubic catheter insertion may be helpful for early urinary continence recovery in patients with Retzius-sparing Robotic-assistant laparoscopic prostatectomy. Advanced pathological tumor stage (T3a–T4) before Retzius-sparing robotic-assistant laparoscopic prostatectomy might be associated with poor urinary control. [ABSTRACT FROM AUTHOR]

Urinary continence recovery after radical prostatectomy is a major issue even in the robotic era. Surgical techniques aimed at improving earlier return to continence are continuously sought. To describe our novel surgical technique of urethral fixation during robot-assisted radical prostatectomy (RARP) and to assess early urinary continence recovery and perioperative complications. A prospective, single-center, single-surgeon cohort of 70 consecutive patients undergoing RARP between January and December 2019 was analyzed. A study group of 35 patients operated on with the urethral fixation technique was compared with a control group of 35 patients receiving standard vesicourethral anastomosis. Urethral fixation versus standard vesicourethral anastomosis during RARP was evaluated. In the study group, the urethral stump was fixed to the dorsal median raphe posteriorly and to the medial portion of the levator ani muscle posterolaterally. The same posterior musculofascial reconstruction incorporating the vesicourethral anastomosis was performed in both groups. Urinary continence recovery, perioperative complications, operating room time, and estimated blood loss were recorded and compared between the two groups. The two groups were comparable with regard to all demographic, clinical, and pathological variables. Recovery of urinary continence at 3 mo after catheter removal was reported by 34 (97.1%) patients in the study and 28 (80%) patients in the control group (p = 0.02). Patients in the study group reported significantly higher rates of urinary continence even at 1 wk and 1 mo after catheter removal compared with the control group (68.6% vs 45.7%, p = 0.04, and 80% vs 54.3%, p = 0.04, respectively). No differences were observed in operating room time (p = 0.7) or estimated blood loss (p = 0.65). Ninety-day postoperative complications were observed in one (2.9%) patient in the study and in four (11.4%) in the control group (p = 0.3). The main limitation is the nonrandomized comparison of relatively small cohorts. In our study, we observed a significant improvement in early urinary continence recovery, with no increase in operating room time or perioperative complications, using the novel urethral fixation technique compared with the standard vesicourethral anastomosis during RARP. We describe our novel surgical technique of urethral fixation during robot-assisted radical prostatectomy. Compared with the standard technique, utilization of our technique was found to be associated with an improved early recovery of urinary continence, with no increase in operating room time or perioperative complications. In a consecutive series of patients undergoing robot-assisted radical prostatectomy, utilization of the novel urethral fixation technique was associated with a significant improvement in early urinary continence recovery, with no increase in operating room time or perioperative complications compared with standard vesicourethral anastomosis.

Objective: Urinary incontinence is one of the most bothersome adversities after robot-assisted radical prostatectomy (RARP). The aim of this study was to investigate the urinary continence recovery and the effect of various surgical techniques. Materials and Methods: We previously reported that posterior rhabdosphincter reconstruction and nerve-sparing were independent predictors of urinary continence recovery 1 month after catheter removal in 199 patients who underwent RARP. Retrospectively, we further reviewed those 199 patients for urinary continence recovery at 3 months or later after RARP. The relationships of urinary continence with perioperative findings, including surgical procedures, were evaluated at 3 to 12 months after RARP. The Fisher exact test and Mann-Whitney rank sum test were used for evaluating variables between the groups. Multivariate logistic regression analysis was performed to investigate the association between urinary continence and perioperative factors. Results: On univariate analyses, surgeon experience, lateral bladder neck preservation (BNP), anterior reconstruction, and posterior reconstruction were significantly associated with urinary continence recovery 3 months after RARP, but only lateral BNP was independently associated with urinary continence recovery in a multivariate analysis. Similarly, on univariate analyses, surgeon experience, lateral BNP, and posterior reconstruction were significantly associated with continence recovery at 6 months or later after surgery. However, multivariate analyses showed that only lateral BNP was significantly associated with urinary continence recovery 6 months or later after surgery. Conclusion: Although the lateral BNP technique did not affect immediate urinary continence recovery, this procedure was significantly associated with continence recovery 3 months or later after RARP.

Clinical data on robot-assisted radical prostatectomy (RARP) performed with the new Hugo robot-assisted surgery (RAS) system are scarce. We described surgical outcomes of 112 consecutive patients who underwent RARP ± extended pelvic lymph-node dissection (ePLND) at OLV Hospital (Aalst, Belgium) between February and November 2022. The median age was 65 yr (interquartile range [IQR] 60-70) and median preoperative prostate-specific antigen (PSA) was 7.9 ng/ml (5.8-10.7). Thirty-eight patients (34%) had International Society of Urological Pathology grade group ≥3 tumor on prostate biopsy. On preoperative magnetic resonance imaging, 26 (23%) patients had a suspicion of extraprostatic disease. The median operative time was 180 min (IQR 145-200) and 27 men (24%) underwent ePLND. On final pathology, 34 patients (31%) had extraprostatic disease and ten (9%) had positive surgical margins. The median number of nodes removed was 15 (IQR 9-19). Among men with data available on the first PSA after surgery, 88% (60/68) had undetectable PSA (<0.1 ng/ml). The probability of urinary continence (UC) recovery was 36% (95% confidence interval [CI] 28-47%) at 1 mo and 81% (95% CI 72-89%) at 3 mo. The median time to UC recovery was 36 d (95% CI 34-44). This is the first report of data on UC recovery and surgical pathology for patients undergoing RARP for prostate cancer performed with the Hugo RAS robotic system. Future investigations with longer follow-up are awaited. PATIENT SUMMARY: We describe surgical outcomes of patients undergoing robot-assisted surgical removal of the prostate for cancer performed with the Hugo RAS robotic system at our institution. In our experience this platform provided adequate results in terms of surgical results and early recovery of urinary continence. Studies with longer follow-up are awaited., (Copyright © 2023 European Association of Urology. Published by Elsevier B.V. All rights reserved.)

Introduction:In the era of minimally-invasive surgery, urinary incontinence (UI) after radical prostatectomy (RP) still represents a troublesome issue for a considerable rate of patients. Factors associated with the risk of post-RP UI, need to be carefully assessed throughout the overall clinical management process thus including the pre-operative, intra-operative and post-operative setting. Areas covered:This review analyses current published evidences regarding clinical and surgical aspects associated with urinary continence (UC) recovery after RP. A careful evaluation of patient’s clinical characteristics should be carried out before surgery in order to properly counsel the patients regarding the risk of UI. In the last two decades, the advent of robotic surgery has led to an overall improvement of functional outcomes after RP, thanks to the development of different surgical strategies based on either the ‘preservation’ or the ‘reconstruction’ of the anatomical elements responsible for urinary continence. Finally, several therapeutic strategies including either a conservative approach, or pharmacological and surgical treatments, should be carefully considered for the post-operative management of UI. Expert commentary:A comprehensive pre-operative patient’s clinical assessment, along with a proper and well-conducted surgical procedure and an effective post-operative care management are essential element to achieve a high probability of UC recovery.

Objectives To investigate the effect of phosphodiesterase type 5 inhibitor on urinary continence recovery after bilateral nerve-sparing radical prostatectomy. Methods We analyzed data of 393 open bilateral nerve-sparing radical prostatectomies carried out between 2005 and 2010. Patients who recovered urinary continence within the first month after catheter removal ( n = 52) were excluded. This resulted in 341 evaluable patients. Urinary continence recovery was defined as being completely pad free over a period of 24 h. Patients were stratified according to postoperative daily ( n = 58; 17%), on-demand ( n = 112; 32.8%) and no ( n = 171; 50.1%) phosphodiesterase type 5 inhibitor use. The effect of phosphodiesterase type 5 inhibitor use on urinary continence was assessed using the Kaplan- Meier method. Uni- and multivariable Cox regression analyses were used to test the association between phosphodiesterase type 5 inhibitor and urinary continence recovery after adjusting for cofounders. Results At a mean follow up of 36.4 months after surgery (median: 33), 288 patients (84.5%) recovered urinary continence after bilateral nerve-sparing radical prostatectomy. Patients who did not use phosphodiesterase type 5 inhibitor after surgery had lower rates of urinary continence recovery at 1- and 2-year follow up as compared with patients taking phosphodiesterase type 5 inhibitor (67.1 vs 86.7% and 76 vs 94.4%, respectively; P < 0.001). After adjusting for all confounders, multivariable analysis showed that phosphodiesterase type 5 inhibitor use, either on demand or daily, had a positive impact on urinary continence recovery ( P = 0.03). Conclusions Patients taking phosphodiesterase type 5 inhibitor have higher urinary continence recovery rates as compared with patients left untreated after bilateral nerve-sparing radical prostatectomy. An improvement in sphincteric and pelvic floor blood supply might be responsible for this beneficial effect associated with the use of phosphodiesterase type 5 inhibitor. [ABSTRACT FROM AUTHOR]

Background: Apical dissection in robot-assisted radical prostatectomy (RARP) affects not only cancer control, but also continence recovery., Objective: To describe a novel approach for apical dissection, the collar technique, to reduce apical positive surgical margins (PSMs)., Design, Setting, and Participants: A total of 189 consecutive patients (81 in the control group, 108 in the collar technique group) underwent RARP at a single center., Primary Outcome: rates of apical PSMs; secondary outcome: urinary continence., Intervention: The urethral sphincter complex is incised 2-3mm distally to the apex, to stay farther from it and reduce PSMs; the underlying smooth muscle is exposed and incised closer to the apex to preserve the maximal length of the lissosphincter., Outcome Measurements and Statistical Analysis: Mann-Whitney U and chi-square tests compared median and proportions between the two groups, respectively. Univariate logistic regression tested the association between technique employed and risk of apical PSMs., Results and Limitations: Fourteen patients (7.4%) revealed apical PSMs (9.9% in the control group, 5.6% in the collar group; p=0.7). When the collar technique was used, significantly lower rates of apical PSMs occurred in pT2 disease (0% vs 7.1%; p=0.03). In case of apical tumor at preoperative magnetic resonance imaging (MRI; n=43), the collar technique determined significantly lower overall (9.7% vs 42%) and apical (3.2% vs 42%) PSMs (all p≤0.02). Continence recovery in the collar and control groups was similar. When preoperative MRI showed an apical tumor, the collar technique had a significantly lower risk of apical PSMs (odds ratio: 0.05, p=0.009)., Conclusions: The collar technique reduces the rates of apical PSMs in case of apical tumor, preserving the length of the lissosphincter., Patient Summary: We describe a novel approach for apical dissection during robot-assisted radical prostatectomy. Our technique reduces the rates of apical surgical margins in case of apical tumor at preoperative magnetic resonance imaging and leads to optimal continence recovery., (Copyright © 2018 European Association of Urology.

Since its introduction in the year 2000, robot-assisted radical prostatectomy (RARP) rapidly diffused, and nowadays roughly 70% of all the radical prostatectomies in the USA are performed using this approach. Interestingly, the broad dissemination of RARP occurred in the absence of comprehensive data coming from prospective randomized trials supporting the superiority of RARP versus the conventional open RP (ORP). Only observations originating from retrospective institutional or large population-based cohorts exist with respect to the comparative effectiveness of the two surgical techniques. What we have learned is that, given an adequate learning curve, RARP leads to better perioperative and long-term functional outcomes compared with ORP, without any compromise to cancer control outcomes. That being said, the substantially higher costs associated with the use of robotics cannot be ignored.
