THE CONTINENT ILEAL RESERVOIR (KOCK POUCH ) - CLINICAL, BIOCHEMICAL AND URODYNAMIC FINDINGS IN 25 PATIENTS

25 patients with a Kock Pouch were reevaluated 366 days after surgery. Early complications occurred in 42 %, late complications were found i n 24 %, including pulmonary embolism, nipple necrosis, incomplere nipp le slipping and stone formation inside the pouch. 12 % of our patients required operative revision of the nipple valves. 88 % proved to be s ocially continent. Urodynamic studies classified 96 % of the pouches a s low-pressure reservoirs. Renal function was preserved, neither elect rolyte imbalances nor chronic manifest metabolic acidosis occurred. Vi tamin B-12-resorption was reduced in 85 %, while serum levels decrease d in 4 patients. Histologically, a reduction of the resorptive surface , signs of chronic inflammation and a constant number of globet cells were found. With a low morbidity and reoperation rate, the Kock Pouch fulfills the demands of a modern urinary diversion.
