Construction of an antirefluxing urinary conduit using a plicated ileocecal segment.

A plicated ileocecal segment was used to construct an antirefluxing urinary conduit in 3 patients. Each patient had markedly dilated or shortened ureters that prevented conventional Leadbetter ureteral reimplantation into a colon conduit. Ascending colon was brought out as a cutaneous stoma, the ureters were anastomosed to ileum, and an antireflux mechanism was created from plicated terminal ileum and the native ileocecal valve. Significant reflux was prevented in all 3 patients. This technique provides a means to prevent urinary reflux into short or dilated ureters, and increases the versatility of the ileocecal segment for use in diversion and urinary tract reconstruction.
