title: Continent urinary reservoir using sigmoid colon and appendix after pelvic exenteration for bulky leiomyosarcoma: a case report.
abstract: We report on a man with bulky leiomyosarcoma occupying the entire pelvic cavity that was treated by pelvic exenteration. A urinary reservoir was constructed using a detubularized segment of sigmoid colon. The appendix was tunneled into the taenia to form a continent catheterizable stoma using the Mitrofanoff principle. Descending colostomy was also created. There is no evidence of recurrence 24 months after treatment and the patient has returned to full physical activity. Continence is complete with a capacity of up to 500 ml. and regular bowel movements. Because of the lack of intestinal anastomosis, this procedure may be recommended as an option for urinary diversion after pelvic exenteration.
