Ureteral obstruction no longer requires routine open surgical diversion. With the advent of percutaneous nephrostomy techniques indwelling ureteral stents, the armamentarium exists to provide drainage by nonoperative means. This has been beneficial to many patients but especially to those who are poor risks or who have terminal illnesses and need treatment for relatively brief periods. Herein we report 2 cases of failure of the double-curved polyethylene ureteral catheter to drain effectively, leading to nephrostomy, and a case in which removal of a stent disrupted a repaired ureteropelvic junction, leading to additional surgery. Three patients also are discussed who had severe dysuria and irritation from the stents.
输尿管梗阻不再需要常规的开放性手术改道。随着经皮肾造瘘技术及留置输尿管支架的出现，已有通过非手术方式进行引流的手段。这对许多患者有益，尤其是那些手术风险高或患有绝症且仅需相对短期治疗的患者。在此我们报告2例双曲聚乙烯输尿管导管引流无效而需行肾造瘘的病例，以及1例因取出支架导致修复的肾盂输尿管连接处破裂而需再次手术的病例。还讨论了3例因支架引起严重排尿困难和刺激症状的患者。
