Abstract
A total of 25 patients 17 to 78 years old (mean age 61 years) underwent bladder replacement with a modified ileocolonic bladder: 20 underwent construction of the neobladder following cystoprostatectomy for invasive bladder tumor, 4 after cystectomy for severe interstitial cystitis and 1 for undiversion. There were 21 men and 4 women. Followup ranged from 3 to 66 months. There were no perioperative deaths. The early complication (perioperative 3 months) and late complication rates were 18% and 16%, respectively. Complications included ureterocolonic anastomotic strictures in 4 ureters (3 were treated via endoscopic retrograde balloon dilation and 1 with endourological antegrade dilation), urethral strictures in 2 patients, treated by urethral dilation, pancreatitis 2 weeks postoperatively in 1 and mild hypercholoremia without concomitant acidosis in 2. One patient presented 3 years postoperatively with a left mid ureteral stone that was managed by ureteroscopic extraction. Three patients died of recurrent carcinoma (none with urethral recurrence). The daytime continence rate was 100% and the nighttime continence rate was 92%. The ureters in this modified ileocolonic bladder were placed in an anatomically correct position to resemble a trigone near the mouth of the neobladder with the left ureter uncrossed. This placement provided easy visualization and instrumentation of the upper urinary tract. No patient had vesicoureteral reflux.
