Ileal Neobladder for Bladder Substitution after Radical Cystectomy

Background: Studer's ileal neobladder is technically simple, and favorable clinical results have been reported. However, there have been only a few follow‐up studies on this type of ileal neobladder. We reviewed the clinical outcomes of patients who received Studer's ileal neobladder, with a minor modification, in our institution. Methods: Twenty‐five men underwent bladder reconstruction with Studer's ileal neobladder after radical cystectomy. The function of the ileal neobladder and voiding status were evaluated during follow‐up. The follow‐up period ranged from 3 to 42 months (mean, 24 months). Results: The ileal neobladder achieved a large capacity at a low basal pressure, associated with a relatively low complication rate directly related to the neobladder. At 12 months after surgery, daytime and nighttime continence rates were 90|X% and 74|X%, respectively. In 5 patients who were incontinent, the maximal urethral closure pressure was statistically lower than in patients with continence. Conclusion: Studer's ileal neobladder is an easy operative procedure for bladder substitution, and has a relatively low complication rate directly related to the neobladder. Good compliance ofthe pouch and preservation of the external sphincter mechanism are the most important factors for achieving urinary continence, after construction of the ileal neobladder.
