Conversion of an ileal conduit to a continent catheterizable stoma.

A technique is described by which a previously constructed ileal conduit is used as an efferent limb of a continent urinary reservoir. The ileal segment is tapered; 1 end is tunneled submucosally into a reconfigured colonic reservoir and the other end is brought to the skin as a catheterizable stoma. This modification of the Mitrofanoff principle provides a highly continent stoma that is easily catheterized, and allows for preservation of the terminal ileum and ileocecal valve within the gastrointestinal tract.
