The percutaneous methods of management of benign ureteral strictures or fistulas have developed as a natural evolution of percutaneous nephrostomy and angiographic techniques. We review our 5-year experience, which includes 18 patients with 19 benign ureteral strictures and 12 patients with ureteral fistulas. In the majority of the patients the ureteral strictures occurred at sites of surgical reconstruction or endoscopic manipulation. All fistulas resulted from surgical injury. In 10 of the 12 patients (82 per cent) the fistulas healed without development of a stricture or need for further intervention. Patients with short ureteral strictures had a high incidence of success and they usually were the best candidates for percutaneous manipulation. The long strictures usually were of longer duration and they were less likely to be managed successfully percutaneously. Failure of percutaneous dilation did not impede subsequent surgical management. Percutaneous management often is a reasonable initial step in the treatment of ureteral strictures and fistulas.
良性输尿管狭窄或瘘管的经皮治疗方法是经皮肾造瘘术和血管造影技术自然发展而来的。我们回顾了我们5年的经验，其中包括18例患有19处良性输尿管狭窄的患者和12例输尿管瘘患者。大多数患者的输尿管狭窄发生在手术重建或内镜操作部位。所有瘘管均由手术损伤引起。12例患者中有10例（82%）瘘管愈合，未出现狭窄或无需进一步干预。输尿管短段狭窄患者成功率高，通常是经皮操作的最佳人选。长段狭窄通常持续时间较长，经皮成功治疗的可能性较小。经皮扩张失败并不妨碍后续的手术治疗。经皮治疗通常是输尿管狭窄和瘘管治疗中合理的初始步骤。
