目的　探讨医源性输尿管损伤的原因、治疗和预防措施。方法　本组 2 3例 ,其中行输尿管逆行放置双J管内引流 6例 ,输尿管端端吻合术 1 4例 ,输尿管膀胱吻合术 1例 ,肾造瘘术 2例 ;6个月后期行管状膀胱瓣输尿管吻合术。结果　切肾率为 0 ,所有患者肾功能均恢复正常。结论　输尿管损伤的治疗以及时恢复其连续性和完整性 ,并放置内支架 (双J管 )引流具有十分重要的意义 ,术前放置输尿管导管和细致规范的手术操作是预防医源性输尿管损伤的关键 Objective To investigate the causes, treatment and preventive measures of iatrogenic ureteral injury. Methods The group of 23 patients, including retrograde ureteral placement of double J tube drainage in 6 cases, ureter end-to-end anastomosis in 14 cases, ureteral anastomosis in 1 case, 2 cases of nephrostomy; 6 months after the implementation of tubular valve Ureteral anastomosis. Results The rate of cut kidney was 0, and all patients returned to normal renal function. Conclusions The treatment of ureteral injury in time to restore its continuity and integrity, and placed stent (double J tube) drainage is of great significance, preoperative placement of ureteral catheter and meticulous standard surgical procedures to prevent iatrogenic ureteral injury The essential
