Minimizing stomal stenosis in appendicovesicostomy using the modified umbilical stoma

Purpose: We describe creation of a modified umbilical stoma as part of continent urinary diversion using appendicovesicostomy. Materials and Methods: Umbilical stomas were created using the eversion-inversion principle in 25 patients undergoing appendicovesicostomy. Results: Mean followup was 3 years. Cosmesis of the umbilical stoma was good in all cases. Stomal stenosis required surgical revision in 8% of cases. Conclusions: We recommend our modified umbilical stomal technique for appendicovesicostomy because it allows good cosmesis without compromising stomal function.
