Appendicovesicostomy: a new technique for bladder diversion during reconstruction of cloacal exstrophy.

Urinary tract diversion in the reconstruction of cloacal exstrophy presents a difficult problem. Many methods have been used, but none has been found to be ideal. We describe a simple technique that incorporates the ileocecal plate in the bladder augmentation, and uses the appendix as a conduit for urinary diversion. This technique offers the advantages of primary closure, effective urinary drainage without tubes, and simplicity of bowel reconstruction with preservation of maximal absorptive surface.
