PURPOSE: To compare the long-term results of minimally invasive endourological intervention versus open surgical revision in patients with nonmalignant ureteroileal stricture. MATERIALS AND METHODS: Retrospective evaluation of 74 patients treated for unilateral or bilateral nonmalignant ureteroileal strictures of 85 renal units. Overall, 96 endourological and 35 open surgical procedures were performed. Balloon dilatation, endoureterotomy by Acucise; or Ho:Yag laser were used as minimally invasive endourological interventions. Open surgical revision with resection of the stricture and open ureteroileal end-to-side-reanastomosis was the alternate treatment modality. Treatment success was defined as radiological normalization or improvement of upper urinary tract morphology combined with the absence of flank pain, infection, ureteral stents or percutaneous nephrostomies. RESULTS: Median follow-up was 29 months (range: 2-177 mos). Overall success rate was 26% (25/96) for endourological interventions versus 91% (32/35) for open surgical revisions (p1cm (p1cm. Only for ureteroileal strictures ≤1cm the success rate for endourological intervention is acceptable. Therefore, ureteroileal strictures >1cm should be primarily treated by open surgical revision.
