PURPOSE: We report our 4-year experience with the chimney modification of the Hautmann ileal neobladder. This modification involves use of an 8 to 12 cm. tubularized isoperistaltic ileal chimney for the ureterointestinal anastomosis. MATERIALS AND METHODS: Between April 1995 and March 1998, 50 men and women with invasive bladder cancer underwent radical cystectomy and creation of a Hautmann neobladder with chimney modification. Complications were assessed, divided as early and late, and subdivided as those related or unrelated to the neobladder. Continence was evaluated using a detailed patient questionnaire. RESULTS: There were no intraoperative deaths. Early complications in 11 of the 50 patients were neobladder related in 5 (10%) and unrelated to the neobladder in 6 (12%). The early reoperation rate was 6%. Late postoperative complications in 10 patients (20%) were neobladder related in 8 (16%) and unrelated to the neobladder in 2 (4%). After 1 year 93% and 86% of patients achieved good day and nighttime continence, respectively. In 2 patients (4%) clean intermittent catheterization is performed and 1 required placement of an artificial urinary sphincter. Ureterointestinal anastomotic strictures were detected in 6 of 100 ureteral units (6%), including 2 with failed initial endoscopic management. Open surgical revision of the ureterointestinal anastomotic site was easier due to the anterior position of the ureters, and identification and mobilization of the isoperistaltic limb. CONCLUSIONS: Our experience with the chimney modification of the Hautmann neobladder compares favorably to other forms of orthotopic urinary diversion in regard to ureteral stenosis, early and late postoperative complications, urinary continence and simplification of the ureterointestinal anastomosis.
