We report 3 cases of ureteral obstruction following aortoiliac prosthetic graft surgery owing to secondary retroperitoneal fibrosis around anteriorly positioned ureters. The reversal of symptoms and radiographic demonstration of relief of obstruction after oral steroid therapy are discussed. The necessity of placing such grafts behind the ureters is reiterated and the routine performance of preoperative and postoperative excretory urography is suggested. A trial of steroid therapy following early detection of such obstruction in lieu of early surgical exploration is discussed.
我们报告了3例主动脉髂动脉人工血管移植术后输尿管梗阻的病例，原因是位于前方的输尿管周围继发腹膜后纤维化。讨论了口服类固醇治疗后症状的缓解以及梗阻解除的影像学表现。重申了将此类移植物放置在输尿管后方的必要性，并建议常规进行术前和术后排泄性尿路造影。还讨论了在早期发现此类梗阻时，先进行类固醇治疗试验而非早期手术探查的情况。
