Background And Objective: The preferable technique for orthotopic bladder substitution after radical cystectomy is debated. The aim of this study was to describe our technique of a stapled W-shaped ileal neobladder and assess the complications and functional results in 100 patients. treated from December 2009 to July 2022.
Methods: The W-shaped ileal neobladder is created with lateral arms of 15 cm and central arms of 10 cm. Following an incision of the lower part of the two medial arms, a 10-cm GIA titanium stapler is used to detubularize the medial arms first and then the laterals to the medial arms. Urethral-neobladder anastomosis and end-to-end ureteroileal anastomosis are finally carried out. We reported on clinical data, complications, and urinary function outcomes assessed by the International Consultation on Incontinence Questionnaire (ICIQ)-Short Form and daytime/24-h pad test. Full urinary continence (UC) was defined as pad tests yielding 0 g.
Key Findings And Limitations: The median surgical time was 210 min. The early (up to 90 d) and late (>90 d) complication rates were 18% (2% grade ≥4) and 11.7% (2% grade ≥4), respectively. Two patients had "late" bladder stones due to chronic urinary retention, whereas none developed calcifications in the neobladder along the stapling lines. Daytime and 24-h UC rates were 74.7% and 72.4% at 12 mo, 82.7% and 72.4% at 36 mo, respectively. Median ICIQ scores were in line with pad test results, being 0 in patients with full UC.
Conclusions And Clinical Implications: Our stapled W-shaped ileal neobladder technique was found to be simple and fast to shape, with a low complication rate, and yielded favorable long-term functional outcomes.
Patient Summary: This study details the surgical technique, complications, and functional outcomes of patients who underwent open cystectomy with a stapled W-shaped ileal neobladder. Our results indicate that this approach is safe and provides favorable long-term functional outcomes.

Objective: This study aimed to compare adverse in-hospital outcomes in ileal conduit versus neobladder urinary diversion type after radical cystectomy (RC) in contemporary versus historical patients.
Methods: Patients were identified within the National Inpatient Sample (NIS 2000-2019). Propensity score matching (PSM; 1:2 ratio) and multivariable logistic regression models (LRMs) were used.

Objective: To compare surgical parameters and short-term outcomes between open radical cystectomy (ORC) and robotic radical cystectomy with total intracorporeal urinary diversion (icRARC).
Methods: Among the study period, 133 patients who underwent ORC and pelvic node dissection for bladder cancer (group 1) were matched and compared to 61 patients who underwent icRARC during the same period (group 2). The groups were matched 1:1 according to their propensity scores adjusted on their baseline demographics and disease characteristics.

Introduction And Importance: Orthotopic neobladder reconstruction may be associated with complications such as neobladder-vaginal fistula (NVF) and uretero-ileal anastomotic stricture which are often managed using stents, though these can be prone to migration.
Case Presentation: We present a 69-year-old lady with a surgical history of radical cystectomy and ileal neobladder that was complicated by a left ureteric stricture and poucho-vaginal fistula for which she underwent a left ureteric stent and bilateral percutaneous nephrostomy (PCN) insertions after which she lost to follow-up. The patient later presented to our center with a right subcostal anterior abdominal wall desmoid tumor for which she underwent wide local excision.

We describe a case of ureteral stricture after radical cystectomy with orthotopic neobladder. The patient presented 4 months after laparoscopic radical cystectomy with intracorporeal orthotopic ileal neobladder, with fever and left lower back pain.Laboratory analysis showed leucocytosis and elevated C reactive protein and creatine levels.

Background: Augmentation cystoplasty (AC) is a useful alternative for the treatment of neuropathic bladder, although there are few studies reporting long-term results. We assess our experience over the last 30-years.
Methods: A retrospective study was conducted in patients with neuropathic bladder in whom AC was performed in our institution between 1990-2020.
