Abstract
Summary Cutaneous urinary diversion requires appliances, unless a pouch and a valve mechanism are used (Kock-pouch). In order to avoid a stoma, repeated self-catheterizations, and the complications which may occur from malfunction of the distal valve, we created a modified ileal pouch with the advantages of a low-pressure system with good capacity and no reflux. By anastomosing the distal part of the reservoir to the urethra and using the male patient's own sphincter, the second nipple can be avoided and a urostoma is obviated. The feasibility of this procedure has been studied in 4 dogs.
