Technique and trial of continent ileocystostomy

To overcome the problem of incontinence which failed to respond to standard measures, an animal model was designed for continent diversion without cystectomy. A tapered terminal ileal segment was implanted in a submucosal tunnel on the anterior aspect of the bladder, and the proximal end of the segment was brought out to the abdominal wall as a stoma that is catheterized intermittently. Ileocystostomy provided continent diversion in 10 dogs at intravesical pressures as high as 45 cm H2O, and there were no changes in serum electrolytes, creatinine, or urea nitrogen concentration.
