OBJECTIVE To describe our institution's experience with Boari flap ureteral reconstruction, specifically focusing on the development of postoperative lower urinary tract symptoms (LUTS). METHODS A retrospective review of all Boari flaps performed at our institution between 2013 and 2023 was performed, excluding patients with urothelial carcinoma and males, given the frequency of LUTS from benign prostatic hyperplasia. Primary outcome was the development of new onset LUTS and subsequent treatment. Secondary outcomes included postoperative infections and ureteral stricture. RESULTS 29 total patients were identified. Mean age was 52.2 years (Standard deviation (SD) 13.1). Mean follow-up was 22.3 months (SD 25.3). Primary reasons for ureteral reconstruction were radiation damage (37.9%) and iatrogenic surgical injury (37.9%). A concurrent psoas hitch was performed in 18/29 (62%) cases, nephropexy was utilized in 1/29 (3.4%) cases, and contralateral bladder pedicles were ligated in 10/29 (34.5%) for increased bladder mobilization. Postoperatively, 8 patients (27.6%) developed new-onset LUTS, effectively managed with oral anticholinergics. Recurrent UTIs occurred in 5 patients (17.2%) and pyelonephritis in one (3.4%) patient. Two patients (6.9%) developed ureteral strictures, one treated with ileal ureter replacement and the other with ureteral balloon dilation. CONCLUSIONS Boari bladder flap ureteral reconstruction leads to moderate rates of new onset LUTS postoperatively, which is important information when counseling women on reconstructive options. Boari flap ureteral reconstruction has a high success rate and serious complications are rare. In the setting of ureteral injury, reconstruction using Boari flaps with or without psoas hitch should be considered for definitive management.
