目的：探讨肾盂输尿管连接部梗阻（UPJO）的后腹腔镜手术治疗方法及临床价值.方法：对20例UPJO患者行后腹腔镜肾盂成形术治疗.结果：全部患者均一次性手术成功,手术时间90～150 min.平均120min术中出血量20～50 ml,平均35 ml;术后住院时间7～10天,平均8天.术后1例出现漏尿,术后10天消失,余无并发症.随访6～52个月,平均20个月,腰痛症状消失,本组患者术后行B超、IVU榆查示肾盂输尿管连接部吻合口无狭窄,肾积水得到改善.结论：后腹腔镜肾盂成形术治疗肾盂输尿管连接部梗阻是安全有效的微创手术方法.

Retroperitoneal Laparoscopic Pyeloplasty for Ureteropelvic Junction Obstruction( Report of 20 cases)

Objective：To evaluate the technique and clinical effects of retroperitoneal laparoscopic surgery for ureteropelvic junction obstruction（UPJO）. Methods： 20 cases with UPJO undergoing retroperitoneal laparoscopic pyeloplasty. Results：All the operations were completed successfully. The operative time was 90 to 150min, an av erage of 120 rain; blood loss was 20 to 50ml, an average of 35ml; postoperative hospital stay was 7 to 10d, an average of 8d. 1 case of leakage of urine for 10 days after operation,The remaining without complications. Postoper-ative follow up time was 6 to 52 months, an average of 20 months. The symptom of lumbodynia disappeared. The ureteropelvic junction anastomoses of all have no stenosis. The hydronephrosis of all were improved. Conclusions： Retroperitoneal laparoscopic pyeloplasty for ureteropelvic junction obstruction is a more effective, safe, minimally invasive surgical techniques.
