Abstract PURPOSE: Transureteroureterostomy is a treatment alternative for ureteral obstruction when more conventionally reconstructive techniques are not feasible. We report on long-term outcomes of patients treated with transureteroureterostomy. MATERIALS AND METHODS: A retrospective chart review of all patients treated with transureteroureterostomy from January of 1985 to February of 2007 was performed. RESULTS: We identified 63 patients who underwent transureteroureterostomy at our institution. Average treatment age was 31.5 years (range 1 to 83). Transureteroureterostomy was performed for 21 (33\%) malignant and 42 (67\%) benign indications. Reconstructions were 30 right-to-left (47.6\%) and 33 left-to-right (52.4\%) with 21 concurrent urinary diversions. There were 16 patients (25.4\%) who received radiation before transureteroureterostomy. Postoperative complications occurred in 15 (23.8\%) patients and were more common in those undergoing diversion for malignancy. Mean followup was 5.8 years (range 0.1 to 22.2) and 5 patients were lost to followup. Of the 56 patients with followup imaging the transureteroureterostomy was patent in 54 (96.4\%) and obstructed in 2 (3.6\%). Mean preoperative and recent calculated glomerular filtration rate for this cohort were 62.8 (range 13 to 154) and 71.8 (range 22 to 141) ml per minute, respectively (p = 0.04). Stone disease developed in 8 patients, and was treated with percutaneous nephrolithotomy (2), spontaneous passage (2), ureteroscopy (1) and surveillance (3). Subsequent urological intervention was required for obstruction or revision in 6 (10.3\%) patients. CONCLUSIONS: We demonstrated the long-term safety and effectiveness of transureteroureterostomy with sustained improvement of renal function compared to preoperative status. Recurrent stricture, distal obstruction and stone disease occur in a small percentage of patients, and can be treated in most with minimal intervention. 2010 American Urological Association Education and Research, Inc.
