An update on the Kock pouch for continent urinary diversion.

The authors continue to feel, based on a 4 1/2 year clinical experience in more than 400 patients, that the Kock continent urostomy offers an important alternative to noncontinent forms of diversion. Not only can it provide an improved body image, but the Kock pouch can also help to salvage, both physically and emotionally, those patients with unsatisfactory results from conduit diversion.
