[目的]探讨输尿管镜钬激光内切开治疗肾盂输尿管连接部再狭窄的安全性和有效性.[方法]2007年3月至2010年12月期间,采用经尿道输尿管镜下钬激光内切开治疗肾盂输尿管连接部再狭窄27例,其中开放性肾盂成形术后17例,腹腔镜下肾盂成形术后10例.术中采用钬激光纵行切开狭窄段后,放置2根4～6F双J管8周.术后3个月复查泌尿系B超、双肾ECT.[结果]术后随访6～24个月,平均14个月,24例影像学检查见肾积水减轻,治疗成功,治愈率为88.9％.[结论]钬激光内切开治疗肾盂输尿管连接部再狭窄安全有效,可为该类患者首选治疗方法.

[Objective]To investigate the safety and efficacy of retrograde ureteroscopic holmium:YAG laser endopyelotomy for correction of recurrent ureteropelvic junction obstruction.[Methods]From March 2007 to December 2010,retrograde ureteroscopic Ho:YAG laser endopyelotomy was carried out in 27 patients with recurrent UPJ obstruction.The patients consisted of 17 cases after open surgery pyeloplasty and 10 cases after laparoscopic pyeloplasty.The obstruction was incised with a holmium laser fiber in a linear fasion.After completing incision,two french-4 to french-6 double-J ureteral stents were left for 8 weeks.The patients were reexamined through B-ultrasound and ECT of kidney after 3 months.[Results]Success was achieved in 24 cases without complication at average follow up for 14 months( 6-24 months).The cure rate was 88.9％.[Conclusions]Retrograde ureteroscopic endotomy using holmium:YAG laser is a safe and minimally invasive therapy for recurrent ureteropelvic junction obstruction.This procedure could be used primarily for these patients.
