Long-Term Functional Outcomes of Ileal and Sigmoid Orthotopic Neobladder Procedures

Abstract Objectives To retrospectively compare the long-term functional outcomes of ileal and sigmoid orthotopic bladder replacements after radical cystectomy. Methods From 1990 to 2004, 123 male patients underwent orthotopic neobladder reconstruction after cystectomy; 75 underwent ileal neobladder (IN) and 48 sigmoid neobladder (SN) procedures. The observation period was 12.3 to 151.6 months (median 61.1). The voiding function of each patient was evaluated at three different observation periods: time 1, less than 5 years; time 2, 5 to 10 years; and time 3, more than 10 years after surgery. Results Almost every SN patient could void without assistance throughout the observation period. In contrast, the rate of spontaneous voiders was significantly low for the IN patients. Daytime continence was significantly worse in the SN than in the IN patients at time 2 ( P P P Conclusions The IN and SN procedures result in different outcomes. The rate of spontaneous voiders was better in the SN group than in the IN group. The IN tends to provide better continence than the SN. In choosing a neobladder procedure, a proper understanding of the prospects of voiding functions is required.
