腹腔镜下手术治疗肾盂输尿管连接部狭窄

目的 评价腹腔镜下手术治疗肾盂输尿管连接部狭窄梗阻(UPJO)的疗效.方法 UPJO患者102例.男56例,女46例.平均年龄31(6～62)岁.左侧53例,右侧49例.102例均经临床及影像学检查证实.肾盂分离平均28(20～46)mm,重度积水21例、中度63例、轻度18例.采用腹膜后径路行离断式肾盂输尿管成形术.术中打开肾周筋膜,以肾下极为标志游离出肾盂输尿管连接部,切除狭窄部分,肾盂输尿管端端连续吻合并留置双J管.结果 102例手术均成功.手术时间平均120(70～180)min,术中出血量平均80(50～100)ml.无严重并发症发生.术后住院平均8.5(6～14)d.102例随访平均9(3～15)个月,经B超复查肾积水消失30例,72例肾盂分离较术前平均减少12(8～26)mm.IVU检查85例吻合口无狭窄.结论 腹腔镜下离断式肾盂输尿管成形术治疗UPJO有效、可行,可以替代开放手术.

Laparoscopic dismembered pyeloplasty for the treatment of ureteropelvic junction obstruction

Objective To discuss the treatment of ureteropelvic junction obstruction by laparoscopic pyeloplasty. Methods A retrospective review of consecutive laparoscopic pyeloplasty in 102 patients between September 2001 and December 2007 was performed. The ureterpelvic junction was dissected and the obstruction portion was excised. Anastomosis was then performed through the ureter and the renal pelvis walls with a stent. Results The mean operating time was 120 min and the average blood loss was 80ml. No major complication occurred intraoperative. The drainage was removed in 3-10 days. The average hospital stay was 8.5 days. The stent was kept for 30-60 days. IVU and B ultrasound examination revealed that the hydronephrosis alleviated during the follow-up and no anastomosis stricture occurred. Conclusions Laparoscopic dismembered pyeloplasty could provide lower morbidity, shorter hospital stay, and faster convalescence. It could be an effective treatment for ureteropelvic junction obstruction.
