Abstract

Different tubular structures have been used to create cutaneous catheterizable continent urinary stomas. The most common complication is stomal stenosis on the cutaneous end of the tubes. We present a variant of stomal stenosis repair that uses a buccal mucosa graft. Between January 2000 and March 2006 stenotic stomal repair was performed in 10 patients between 3 and 17 years old (mean age 6). A Mitrofanoff channel was created from a bladder tube in 4 patients, from appendix in 3, from ileum in 2 and from the ureter in 1. The procedure involved the removal of scar tissue and the creation of well vascularized dermal beds by skin de-epithelialization (epidermis removal). After that we formed 2 elliptical dermal flaps. Two elliptical buccal mucosa grafts were quilted to the recipient bed (the dermal flap) and anastomosed with the mucosa of the normal part of the channel. The flaps were joined, tubularized and sutured to the skin. An indwelling catheter was left in the channel for 2 weeks. Postoperatively the buccal mucosa was wetted with saline solution for 4 consecutive days. Followup was between 12 and 39 months (mean 22). There was no partial or total graft necrosis. None of the patients experienced repeat stenosis. The stoma w...Continue Reading
