Ureteral stenting is a technique-demanding procedure performed during robot-assisted laparoscopic ureteral reimplantation (RALUR). Many stenting techniques have been reported; however, none of them could be accepted as an ideal way.
The aim of the study was to report our initial results of a modified stenting technique for RALUR.
Consecutive 4 patients undergoing RALUR were prospectively enrolled into our study. Our ureteral stenting technique included the following steps: catheterize a head-cut Foley catheter at the beginning of the operation, drag out the Foley catheter from the ureterovesical stoma after finishing posterior anatomosis, insert a guide wire through the catheter to the ureter lumen, and place the double-J (DJ) stent over the guide wire with a pusher.
All surgeries were successfully performed without severe complications. The mean stenting time was 1.6 min. No submucosa pseudocanal was found during stenting. DJ stent was removed 4 weeks after surgery. During the 3-month follow-up, it was observed that no vesicoureteral reflux or ureter stricture was found.
Our ureteral stenting technique is an effective, simple, and safe procedure in RALUR, and could also be performed in laparoscopic ureteral reimplantation.
输尿管支架置入术是机器人辅助腹腔镜输尿管再植术（RALUR）中一项对技术要求较高的操作。已有多种支架置入技术被报道；然而，尚无一种可被视为理想方法。
本研究旨在报告我们改良的RALUR输尿管支架置入技术的初步结果。
连续4例行RALUR的患者被前瞻性纳入本研究。我们的输尿管支架置入技术包括以下步骤：手术开始时插入一根头部剪开的Foley导管，后腹膜吻合完成后从输尿管膀胱吻合口拉出Foley导管，通过导管将导丝插入输尿管腔，并用推送器将双J（DJ）支架置于导丝上。
所有手术均成功完成，无严重并发症。平均支架置入时间为1.6分钟。支架置入过程中未发现黏膜下假道。术后4周取出DJ支架。在3个月的随访中，未发现膀胱输尿管反流或输尿管狭窄。
我们的输尿管支架置入技术在RALUR中是一种有效、简单且安全的操作，也可用于腹腔镜输尿管再植术。
