To evaluate the efficacy of percutaneous balloon dilatation and temporary internal stenting in the treatment of transplant ureteral strictures.
Nine patients presenting with obstructed renal transplants were treated by antegrade nephrostomy insertion, ureteroplasty, and temporary internal stenting. Following stent removal, patients were divided into two groups for analysis according to whether the obstruction occurred less than (group A) or more than (group B) 3 months following transplantation.
All procedures were technically successful. In group A (n = 6), all patients were successfully treated by one or two dilatations with stenting. In group B (n = 3), two patients were successfully treated by one dilatation with stenting. Overall, eight patients (89%) have had their primary or secondary stent removed successfully at a mean interval of 97.5 days after insertion, and remain well at a mean follow-up interval of 22 months.
Balloon dilatation and temporary internal stenting is a useful method for treating transplant ureteral strictures.
评估经皮球囊扩张及临时性内支架置入术治疗移植肾输尿管狭窄的疗效。
对9例移植肾梗阻患者行顺行性肾造瘘置管、输尿管成形术及临时性内支架置入术。支架取出后，根据移植后梗阻发生时间是否小于3个月（A组）或大于3个月（B组）将患者分为两组进行分析。
所有手术操作均技术成功。A组（n = 6）中，所有患者经一至两次扩张并置入支架后均成功治愈。B组（n = 3）中，2例患者经一次扩张并置入支架后成功治愈。总体而言，8例患者（89%）在支架置入后平均97.5天成功取出了初次或二次置入的支架，在平均22个月的随访期内情况良好。
球囊扩张及临时性内支架置入术是治疗移植肾输尿管狭窄的一种有效方法。
