abstract
PURPOSE: The ureteroileocecal appendicostomy reservoir is designed to potentially decrease the morbidity of continent diversion, particularly in previously irradiated patients. We report our experience with this reservoir to compare complications in irradiated and nonirradiated patients. MATERIALS AND METHODS: The records of 52 consecutive patients who underwent ureteroileocecal appendicostomy diversion between March 2001 and January 2008 were evaluated. Outcomes were analyzed according to whether patients received radiation therapy to the pelvis. Complications were reported as early (within 90 days of surgery) or late. RESULTS: Overall 29 patients received radiation therapy. The incidence of early complications requiring operative intervention was 14%, including 2 patients (9%) with and 5 (17%) without radiation (p = 0.68). All except 1 reoperation was done to revise the stoma. Early urinary tract infections developed in 17% of nonirradiated and 28% of irradiated patients (p = 0.51). The most common late complication was stomal stenosis requiring dilation on an outpatient basis, which occurred in 21% of patients, including 4 with (17%) and 7 without (24%) radiation (p = 0.74). Late ureteral complications requiring intervention were reported in 15% of renal units, including 2 of 44 without (5%) and 6 of 56 with (11%) radiation (p = 0.21). CONCLUSIONS: Ureteroileocecal appendicostomy is a safe, effective technique for continent cutaneous urinary diversion in heavily irradiated patients. Complication rates did not significantly differ between irradiated and nonirradiated patients, and appear improved compared to those in previous reports.
