From May 1985 through July 1987, 22 patients underwent Kock continent ileal reservoir for urinary diversion. There were 19 males and 3 females, between 38 and 82 years old (mean age 63.1 years). A one-stage radical cystectomy and Kock pouch construction were performed in 21 patients. One patients was converted from standard ileal conduit to this new reservoir. The keys to success of the Kock pouch are creation and maintenance of the nipple valve to prevent reflux and to ensure continence. Mesenteric fat is removed with CUSA for 8 cm along the afferent-efferent limbs of the pouch and exclusion of mesentery is limited for only 3-4 cm. This important modification will ensure adequate ileal intussusception and vascular supply to the valves. To prevent eversion and prolapse, the nipple valve is anchored to the wall of reservoir. A strip of sauvage filamentous Dacron serves as a collar to fix the afferent-efferent limbs to the pouch. There were 2 postoperative deaths and two major early complication: 1 acute renal failure and 1 intestinal fistula, both of which were treated conservatively. Late complications occurred in 6 patients. Of these 6 patients, 1 required reoperation and revision of the continence valve mechanism and 1 required hospitalization for entero-pouch fistula. Serum electrolytes and vitamin B12 remained normal in all patients. Patients perform self-catheterization every 4-6 hours during the day and once at night for volumes ranging up to 1,000 ml. The end result in 19 of 20 patients was excellent.(ABSTRACT TRUNCATED AT 250 WORDS)
