Augmentation cystoplasty as a third-line therapy for neurogenic detrusor overactivity performed by an open approach has long been studied. Few laparoscopic and robot-assisted series have been reported. To evaluate the feasibility, safety, and functional outcomes of completely intracorporeal robot-assisted supratrigonal cystectomy and augmentation cystoplasty (RASCAC) in patients with refractory neurogenic detrusor overactivity. We identified all patients undergoing RASCAC, as treatment for refractory neurogenic detrusor overactivity, from August 2016 to April 2018. RASCAC was performed in all cases using a standardized technique with the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) in a four-arm configuration. Perioperative data, and functional and urodynamic results at 1-yr follow-up were assessed. Statistical analysis was performed using Stata version 15.1. Ten patients were identified. No conversion to open surgery was needed. The median operative time was 250 (interquartile range 210-268) min, the median estimated blood loss was 75 (50-255) ml, and the median hospitalization time was 12 (10.5-13) d. The 30-d major complication rate was 10%. Two patients presented a late urinary fistula; in one of the cases, surgical revision was needed. In both cases, low compliance to intermittent self-catheterization was identified. At 1-yr follow-up, functional and urodynamic outcomes were excellent. Robot-assisted augmentation cystoplasty has been shown to be safe and feasible, with a reasonable operative time and low complication rate in experienced hands. A higher number of patients and longer follow-up are, however, warranted to draw definitive conclusions. In this report, we look at the outcomes of robot-assisted supratrigonal cystectomy and augmentation cystoplasty in neurourological patients. Perioperative, functional, and urodynamic results are promising. Further studies with a longer follow-up are needed to confirm these findings.

Introduction: To evaluate Enhanced recovery after surgery (ERAS®) protocol on oncological outcomes for patients treated with radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB). Methods: A prospectively maintained single-institutional database comprising 160 consecutive UCB patients who underwent open RC from 2012 to 2020 was analyzed. Patients receiving chemotherapy and those with a urinary diversion other than ileal conduit were excluded. Patients were divided into two groups according to the perioperative management (ERAS® and pre-ERAS®). The study aimed to evaluate the impact of the ERAS® protocol on survival at five years after surgery using a Kaplan–Meier log-rank test. A multivariable Cox proportional hazards model was used to identify prognostic factors for cancer-specific (CSS) and overall survival (OS). Results: Of the 107 patients considered for the final analysis, 74 (69%) were included in the ERAS® group. Median follow-up for patients alive at last follow-up was 28 months (interquartile range [IQR] 12–48). Five-years CSS rate was 74% for ERAS® patients, compared to 48% for the control population (P = 0.02), while 5-years OS was 31% higher in the ERAS® (67% vs. 36%, P = .003). In the multivariable analysis, ERAS® protocol and tumor stage were independent factors of CSS, while ERAS®, tumor stage so as total blood loss were independent factors for OS. Discussion: A dedicated ERAS® protocol for UCB patients treated with RC has a significant impact on survival. Reduction of stress after a major surgery and its potential improvement of perioperative patient’s immunity may explain these data.

Background: Despite existing standardized surgical techniques and the development of new perioperative care protocols, radical cystectomy (RC) morbidity remains a serious challenge for urologists. Postoperative ileus (POI) is one of the most common postoperative complications, often leading to a longer length of stay (LOS). The aim of our study was to assess the impact of compliance to the Enhanced Recovery After Surgery (ERAS®) protocol on bowel recovery, 30-day complications and LOS after RC for bladder cancer (BC). Methods: Data from consecutive patients undergoing RC for BC within an ERAS® dedicated protocol were analyzed. Exclusion criteria were urinary diversion other than ileal conduit and palliative RC. Patients were divided into two groups according to their compliance (A: low-compliance and B: high-compliance). ERAS® compliance was extracted from the ERAS® Interactive Audit System (EIAS) database. Postoperative complications were prospectively recorded by a dedicated study nurse 30 days after RC. POI was defined as the placement of a nasogastric tube. Logistic regression analysis was used to identify predictors of 30-day complications and POI. Results: After considering the exclusion criteria, 108 patients were included for the final analysis. The median global compliance to the ERAS® protocol was 61%. A total of 78 (72%) patients had a compliance 65% (group B). No significant differences were found among the two groups regarding the 30-day complication rate (86% in group A versus 73% in group B, p = 0.82) and LOS (14 days in group A versus 15 days in group B, p = 0.82). The time to stool was significantly shorter in group B (4 days versus 6 days, p = 0.02), and the time to tolerate solid food was slightly faster in group B but not significant (8 versus 7 days, p = 0.23). The POI rate was significantly lower in patients with a higher ERAS® compliance (20% versus 46%, p = 0.01). A multivariate analysis showed that ERAS® compliance was not significantly associated with 30-day total complications. However, a lower compliance to the ERAS® protocol and age > 75 years were significant independent predictors of POI. Conclusions: Our study provides further evidence to support the beneficial effect of the ERAS® protocol in patients undergoing RC, particularly in terms of facilitating a faster recovery of bowel function and preventing POI. Future research should focus on investigating novel approaches and interventions to improve compliance with the ERAS® protocol. This may involve patient education, multidisciplinary teamwork, and continuous quality improvement initiatives.

Objective: To present the protocol for a randomized controlled trial (RCT) evaluating the efficacy and safety of transcutaneous tibial nerve stimulation (TTNS) for refractory neurogenic lower urinary tract dysfunction (NLUTD). Study Design and Results: bTUNED (bladder and TranscUtaneous tibial Nerve stimulation for nEurogenic lower urinary tract Dysfunction) is an international multicentre, sham‐controlled, double‐blind RCT investigating the efficacy and safety of TTNS. The primary outcome is success of TTNS, defined as improvements in key bladder diary variables at study end compared to baseline values. The focus of the treatment is defined by the Self‐Assessment Goal Achievement (SAGA) questionnaire. Secondary outcomes are the effect of TTNS on urodynamic, neurophysiological, and bowel function outcome measures, as well as the safety of TTNS. Conclusions: A total of 240 patients with refractory NLUTD will be included and randomized 1:1 into the verum or sham TTNS group from March 2020 until August 2026. TTNS will be performed twice a week for 30 min during 6 weeks. The patients will attend baseline assessments, 12 treatment visits and follow‐up assessments at the study end.

Lower urinary tract dysfunction is often observed in patients with multiple sclerosis (MS) and may be responsible for an increased risk of upper urinary tract (UUT) damage. Although there are well-known urodynamic risk factors for UUT damage, no clinical prediction parameters are clearly identified. We aimed to confirm the accuracy of the Expanded Disability Status Scale (EDSS) in predicting urodynamic risk factors for UUT deterioration and to assess other clinical parameters potentially predicting urodynamic risk factors. We retrospectively reviewed 201 patients with MS referred for primary neuro-urological work-up, including a video-urodynamic study (VUDS) from August 2009 to February 2020. Multivariate modeling revealed EDSS, male gender, and a number of LUTS as clinical parameters significantly associated with urodynamic risk factors for UUT damage (p = 0.06, p = 0.01, p = 0.02, respectively). A nomogram combining EDSS, male gender, and a number of different LUTS was created to predict the presence of at least one urodynamic risk factor for UUT damage. In conclusion, the presence of high EDSS combined with male gender and several different LUTS is significantly associated with urodynamic risk factors and can be used to stratify MS patients for further neuro-urological assessment and treatment.

Background: Cystectomy with urinary diversion (CUD) is a highly morbid surgery. Despite implementing an enhanced recovery after surgery (ERAS®) protocol, postoperative respiratory complications (PRC) within 30 days after surgery remain frequent. This study aims to identify patients at higher risk of developing PRC after CUD. Methods: We conducted a retrospective analysis of 242 patients who underwent CUD at Lausanne University Hospital from 2012 to 2022, adhering to ERAS® guidelines. Data on postoperative complications, including pneumonia, respiratory failure, pulmonary embolism, lobar atelectasis, and pleural effusion, were analyzed. Chi-square and Mann–Whitney U tests compared patients with and without PRC. A multivariable Cox model identified independent prognostic factors. Results: PRC occurred in 41 patients (17%). Those with PRC experienced longer hospital stays and higher 30-day mortality rates. Poor ERAS® compliance was a significant risk factor. Multivariable analysis showed pneumonia was associated with postoperative ileus, while pulmonary embolism correlated with infectious and cardiovascular complications. Conclusions: PRC result in extended hospitalization and decreased survival. Rigorous adherence to ERAS® protocols, including early mobilization, respiratory physiotherapy, and avoiding nasogastric tubes, is essential for preventing PRC.
