Abstract
All existing continent urinary reservoirs utilize cecum and/or varying lengths of ileum. In patients who have received prior pelvic radiation therapy, continent diversion has not been feasible because those segments of bowel lie within the field of irradiation. We describe a new technique of continent diversion utilizing only bowel outside the field of pelvic irradiation. A urinary reservoir is constructed from reconfigured transverse colon. A tubularized segment of stomach is implanted beneath the taenia of the reservoir to provide a continent, catheterizable stoma. We describe this technique in detail and report our results in five dogs followed for a mean of 59 days.
