The ileal neobladder: complications and functional results in 363 patients after 11 years of followup

Abstract

Purpose: Since 1986 orthotopic lower urinary tract reconstruction using the ileal neobladder has been our diversion of choice in patients of both sexes undergoing cystectomy. We report on experience and functional results of the first 363 men 11 years after this procedure.

Materials and methods: Complications were assessed, tabulated, subdivided into early (3 months or less postoperatively) and late types, and further categorized with respect to relationship to neobladder construction. Continence and voiding pattern were individually evaluated via a detailed patient questionnaire.

Results: Perioperative death occurred in 11 patients (3%). Neobladder related early and late complications occurred in 56 (15.4%) and 85 (23.4%) of the 363 patients, respectively. Neobladder related early and late abdominal reoperation rates were 0.3 and 4.4%, respectively. Perioperative neobladder unrelated early complications were observed in 122 patients (33.6%) and 44 (12.1%) required operative treatment. Late postoperative complications unrelated to the neobladder occurred in 45 patients (12.4%) and 19 required open surgical revision. Of 290 evaluable patients 96.1% void spontaneously, 3.9% perform clean intermittent catheterization in some form and 1.7% perform regular intermittent catheterization. Daytime and nighttime continence was reported as good by 95.9% and satisfactory by 95% of the patients. Unacceptable daytime continence requiring more than 1 pad per day occurred in only 4.1% of the patients and only 5% are wetting more than 1 pad a night.

Conclusions: The ileal neobladder produces good functional results and can be constructed with acceptable complications. Our data suggest that although it is not a complication-free procedure, we advocate its use when possible.
