Eleven kidneys in 10 patients (mean age 80 years) presenting over a period of 1 year with obstruction of the lower ureter secondary to malignant obstruction (8 patients), stone disease (1 patient), and bladder wall hypertrophy (1 patient) underwent nephrostomy with subsequent immediate or delayed antegrade stenting. An antegrade placement of the stent was achieved in 10 of the 11 kidneys (90% success). In three cases a combined procedure was performed with cystoscopic assistance. In most cases there was rapid improvement of renal function following stenting. Insertion of ureteric stents in patients admitted to hospital with malignant ureteric obstruction allowed treatment of their renal failure and subsequent discharge without use of permanent external urinary diversion appliances. No significant complications of the procedure were encountered. Medium term follow-up of patients stented for malignant ureteric obstruction suggests that the stents can be left in place without replacement for up to 20 months.
10名患者（平均年龄80岁）的11个肾脏在1年的时间里因恶性梗阻（8例）、结石病（1例）和膀胱壁肥厚（1例）导致输尿管下段梗阻而接受了肾造瘘术，随后立即或延迟进行顺行支架置入。11个肾脏中有10个成功进行了支架顺行置入（成功率90%）。3例在膀胱镜辅助下进行了联合手术。大多数病例在支架置入后肾功能迅速改善。因恶性输尿管梗阻入院的患者置入输尿管支架后，可治疗肾衰竭，随后无需使用永久性外部尿液改道装置即可出院。该手术未出现重大并发症。对因恶性输尿管梗阻置入支架的患者进行中期随访表明，支架可留置长达20个月而无需更换。
