Continent cecoileal conduit: preliminary report.

A continent cecoileal conduit to improve rehabilitation after external urinary diversion is described. The isolated cecum functions as a reservoir. The continence mechanism is constructed by intussuscepting the terminal ileum into the isolated cecum to form a nipple, preventing leakage of urine. The kidneys are protected from cecoureterorenal reflux by ureterocecostomies with submucous tunnels. We have used this technique on 4 patients, 2 of whom need no external urinary pouch since the urostoma is absolutely continent. One patient became incontinent 3 months postoperatively and is wearing a conventional bag and 1 patient died. There is no refluex into the kidneys. The upper urinary tract, which is dilated slightly 4 weeks postoperatively, tends to become normal after a few months.
