经皮肾微创穿刺造瘘治疗输尿管上段结石

目的　探讨经皮肾微创穿刺取石术治疗输尿管上段结石的方法和疗效。方法　回顾性分析 12 6例采用经皮肾微创穿刺治疗输尿管上段结石的临床资料。采用B超引导经皮肾穿刺建立 16～ 18F大小皮肾通道 ,使用 8 9.8F输尿管肾镜 ,结合电子弹道碎石、MCC电脑灌注泵进行手术。结果　 12 6例均Ⅰ期取石术 ,结石取净率 10 0 % ,手术时间 2 5～ 75min ,平均 5 0min ,手术后住院时间平均 5 .5d。并发输尿管梗阻 3例。结论　经皮肾微创穿刺取石术治疗输尿管上段结石疗效确切 ,具有创伤小、康复快的优点 ,单用B超引导建立皮肾通道即可 ,值得推广应用

Mini-percutaneous nephrolithotomy in treatment of proximal urethral calculi

Objective To evaluate mini-percutaneous nephrolithotomy in proximal urethral calculi. Methods 126 cases of proximal urethral calculi treated with mini-percutaneous nephrolithotomy from August 2001 to April 2004 were studied retrospectively. Percutaneous nephrostomy was established solely under the guide of B-ultrasound.Results 126 cases were rendered stone free at 1 session. The average surgical time was 50 minutes, the estimated blood loss volume was 35 ml and the average hospital stay after operation were 5.5 days. 3 patients needed open surgery for the reasons of renal or urethral complications.Conclusions Treatment of proximal urethral calculi by mini-percutaneous nephrolithotomy is safe, effective and less invasive. Solely sonographic guidance is available to the procedure.
