Abstract
A series of 41 patients with a continent ileal reservoir for urinary diversion (Kock pouch) was studied with regard to voiding pattern (voiding frequency), voided volume, urinary composition, bacterial contamination and muscus secretion. The mean voiding frequency in 21 patients was 5/24 h and the time required for the procedure, including the time to cover the stoma with a bandage, was 3 to 5 min; 2 patients voided once or twice a night, while 19 patients never did so. The mean volume voided during the day were significantly smaller than the volume voided in the morning. The total 24-h urinary volume exceeded that of normal individuals but the 24-h secretion of electrolytes was within normal limits. Bacterial contamination was found in most samples of urine. Evacuation was not impeded by the rich mucus content of the urine and mucus production did not diminish with time.
