The most important surgical complications of renal transplantation are stenosis and obstruction of anastomosis of the ureter to the bladder. Although the routine use of the ureteral stents to prevent such complications seems rational, the optimal time to keep the ureteral stent is still controversial.
This study presents the benefits and complications of removing the ureteral stent based on the elapsed time after the surgery.
All patients who underwent kidney transplantation between May 2011 and August 2014 in Modarres hospital, Tehran, Iran, were enrolled in the study. The patients were classified into three groups. The ureteral stent was removed 10, 20, and 30 days after the transplantation in these groups.
A total of 529 patients underwent kidney transplant surgery in our center. Urologic complications among the three groups consisting of hydronephrosis, urinoma and collection did not have statistically significant differences.
Ureteral stent can be picked up with no increased risk of urologic complications at shorter intervals after the kidney transplantation surgery.
肾移植最重要的手术并发症是输尿管与膀胱吻合口狭窄和梗阻。虽然常规使用输尿管支架预防此类并发症似乎合理，但保留输尿管支架的最佳时间仍存在争议。
本研究基于术后经过的时间，介绍取出输尿管支架的益处和并发症。
2011年5月至2014年8月在伊朗德黑兰莫达雷斯医院接受肾移植的所有患者均纳入本研究。患者分为三组。这些组分别在移植后10天、20天和30天取出输尿管支架。
本中心共有529例患者接受了肾移植手术。三组中的泌尿系统并发症，包括肾积水、尿瘤和积液，在统计学上没有显著差异。
肾移植手术后较短时间内取出输尿管支架，不会增加泌尿系统并发症的风险。
