Experimental continent diversion

Urinary diversion utilizing a continence‐maintaining ileal valve has been performed in 12 canines. This procedure offers a simple surgical procedure and uses the diversion's internal fluid pressure to maintain continence. Of 12 canines with this continence‐maintaining ileal valve, 11 remained continent at sacrifice. Operative complications were minimal and late complications occurred in 2 dogs. Histological evaluation of the diversionary tissues revealed slight changes in the mucosa of the ileal valve, with some flattening of the villi. This procedure may have a clinical role in urinary diversion for patients with pelvic malignancy or patients who need urinary diversion for other reasons.
