OBJECTIVE
Ureteral stents are used to reduce urologic complications after renal transplantation. However, they predispose to infection. The optimal time to keep them in the urinary tract has not yet been defined. The aim of this study was to evaluate the effect of early removal at the end of 2 weeks on urinary tract infections and early urologic complications (within 3 months), such as ureteroneocyctostomy leakage as well as ureteral anastomosis stricture or obstruction.
METHODS
We retrospectively analyzed the medical records of 48 patients who underwent renal transplantation using a ureteral stent. The patients were divided into two groups according to the time of stent removal: at the end of 2 weeks (group A; n = 10) versus at a later time (group B; n = 38).
RESULTS
The urologic complication rate was 0% in group A and the urinary tract infection rate, 2%. The urologic complication rate was 0% in group B and the urinary tract infection rate, 35%.
CONCLUSION
Early removal of the stent at the end of 2 weeks after renal transplantation is decreased the rate of urinary tract infections.
目的
输尿管支架用于减少肾移植术后的泌尿系统并发症。然而，它们易引发感染。在尿路中留置支架的最佳时间尚未确定。本研究的目的是评估在2周结束时早期拔除支架对尿路感染及早期泌尿系统并发症（3个月内）的影响，如输尿管膀胱吻合口漏以及输尿管吻合口狭窄或梗阻。
方法
我们回顾性分析了48例接受输尿管支架肾移植患者的病历。根据支架拔除时间将患者分为两组：2周结束时拔除（A组；n = 10）与稍后拔除（B组；n = 38）。
结果
A组泌尿系统并发症发生率为0%，尿路感染率为2%。B组泌尿系统并发症发生率为0%，尿路感染率为35%。
结论
肾移植术后2周结束时早期拔除支架可降低尿路感染率。
