PURPOSE: Since 1986 orthotopic lower urinary tract reconstruction using the Kock ileal neobladder has been our diversion of choice in patients undergoing cystectomy. We report on the first 295 male patients undergoing this procedure from May 1986 through December 1993. 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 was individually evaluated via a detailed patient questionnaire. RESULTS: The pouch related early and late complication rates were 7.2 and 11.6%, respectively, and pouch related abdominal reoperation rates were 0.0 and 1.4%, respectively. Analysis of late pouch related complications revealed 4.1% stone formation and 2.4% afferent nipple stenosis rates, and only 1 case (0.3%) of ileal urethral anastomotic stricture. Of the patients 87 and 86% reported good or satisfactory daytime and nighttime continence, respectively. With regard to age, while overall continence was similar, a significantly greater percentage of patients younger than 70 years experience good daytime and nighttime continence relative to the older counterparts. Of the patients 5% perform regular intermittent catheterization and 2.7% required an artificial urinary sphincter due to unacceptable continence. CONCLUSIONS: The Kock orthotopic ileal neobladder can be constructed with minimal morbidity and extraordinary functional results. We strongly advocate its use when possible.
