Comparative performance of the different orthotopic urinary diversions

Abstract

Purpose of review: Majority of patients undergoing radical cystectomy are suitable for orthotopic urinary diversion. The effect of different techniques of neobladder reconstruction on early and long-term postoperative complications is still being determined. Additionally, it is unclear which type of neobladder provides the best patient satisfaction. The purpose of this article is to review the outcomes of different orthotopic urinary diversions following radical cystectomy.

Recent findings: Ileal neobladder is the preferred type of orthotopic urinary diversion following radical cystectomy. Hautmann and Studer, which are the most common orthotopic diversion techniques, provide daytime continence rate up to 87% and 92%, respectively. However, nighttime continence is achieved in about 50% of patients. High-level evidence supports the long-term safety of orthotopic neobladder in terms of renal function, even in patients with a glomerular filtration rate <60 ml/min. Sexual dysfunction is the only independent factor associated with poorer quality of life in these patients.

Summary: The best type of neobladder is still uncertain. However, Studer and Hautmann are the most commonly performed techniques that provide favorable short- and long-term outcomes.
