A new technique of using the in situ appendix as a catheterizable stoma in continent urinary reservoirs.

A new technique of using the in situ appendix to construct a continent catheterizable stoma is described in a patient who underwent continent urinary diversion, and the technical aspects of this procedure are illustrated in detail. The appendix is remodeled by invaginating its base into the cecum for 1 cm., cecoplicating the middle portion for 2 cm. and bringing the distal end to the skin as a cutaneous stoma. This new technique demonstrates that the in situ appendix can be constructed successfully to provide continence without the need for isolating it from the cecum and implanting the distal end into the urinary reservoir as described in the Mitrofanoff technique.
