Abstract
The operative procedure used in the present series involved a nerve‐sparing radical cystectomy, with anastomosis of the urethra using a pouch made of detubularized ileum. The 36 patients who underwent this operation were all male with an average age of 58. No deaths resulted from the operation. As far as late complications were concerned, malfunction of the antireflux nipple valve was noted in 1 patient and stenosis occurred between the urethra and pouch in 2. One patient was found to have multiple stones in the pouch and reservoir decompensation was recognized in 2. Thus, the late complication rate was 17%. There were no cases of total incontinence, but nocturnal incontinence appeared in 11 out of 31 (35%). A total of 20 out of 25 patients (80%) recovered their erectile function during the postoperative follow‐up period and the disease‐free survival rate at 5 years was 78%. Therefore, the urethral Kock pouch combined with nerve‐sparing cystectomy has proved to be a useful procedure as far as the quality of life is concerned.
