Continent urostomy: a clinical experience in 20 patients.
Urinary diversion via a continent ileal reservoir (modified Kock's procedure) was performed in 20 patients. Primary continent urostomy construction was carried out in 6 patients. Previous urinary diversion was present in 12 patients. Two patients were referred to us because a previous attempt to construct a continent reservoir urostomy had failed. There was no operative mortality. Three early complications occurred in 3 patients. Leakage from a uretero-enteric anastomosis in one patient and necrosis of a continence-providing valve in another patient necessitated reoperation. Late complications causing malfunction of the nipple valves required revisional surgery in 2 patients. Stoma stricture developed in 1 patient after 5 months and could be corrected surgically. The functional results were excellent. Continence was achieved without reflux to the upper urinary tract. Instead of a Kock pouch, an S-pouch was used. The continence and antireflux-providing valves were stapled to the reservoir wall. Slippage of the nipple valves did not occur. All our patients had consistently positive urine cultures and were without complaints. In a few cases, stone formation was observed usually on the staples at the tip of the valve. The stones were removed by forceps during endoscopy of the reservoir.
