FURTHER EXPERIENCE WITH THE URETHRAL KOCK POUCH

In 185 men a urethral Kock pouch was constructed as a bladder substitute after radical cystectomy for cancer. A total of 117 patients was followed for a minimum of 1 year and is fully evaluable. Of the patients 108 (92%) are completely continent during the day, while 85 (73%) are dry at night. Also, 8 patients had an excellent response to imipramine hydrochloride. Stability or improvement in the configuration of the upper tract was noted in 210 renal units (90%). A total of 24 renal units showed evidence of deterioration due to reflux (16) and an anastomotic stricture (8). Stability of the antireflux nipple valve was ensured by creation of a window in the mesentery of the corresponding bowel segment and by anchoring the valve to the wall of the pouch by an additional row of staples. On the basis of this favorable outcome the procedure is recommended for male patients for whom cystectomy is indicated and in whom the urethra can be preserved.
