B超引导下经皮肾镜取石术治疗上尿路结石1289例临床总结

目的 探讨B超引导下PCNL治疗上尿路结石的有效性与安全性. 方法 2004年6月至2009年7月行超声引导下PCNL 1289例.其中输尿管上段结石386例;肾单发结石463例,多发结石355例,鹿角形结石85例.结石大小0.8 cm×1.2 cm～9.0 cm×5.3 cm,平均2.1 cm×3.1 cm.伴不同程度肾积水935例. 结果 1289例无中转开放及死亡.平均手术时间90(55～220)min,平均术中出血量175(60～800)ml.术中、术后输血31例,术后因出血行超选择性肾动脉栓塞术14例(1.09%).一期单通道取石1105例,二通道取石108例,三通道取石76例.一期结石取净率85.03%(1096/1289);193例结石残留者中,67例行ESWL,126例行二期PCNL,其中85例结石取净.总结石取净率91.62%(1181/1289).结论 B超引导下PCNL治疗上尿路结石具有定位准确、工作通道建立安全简便、结石取净率高、创伤小、并发症少等特点,手术适应证选择、手术技巧掌握、相应配套设施的保障是PCNL成功的关键.

Summary of 1289 percutaneous nephrolithotomy cases under ultrasonic guidance for the treatment of upper urinary calculi

Objective To evaluate the efficacy and safety of percutaneous nephrolithotomy (PCNL) under ultrasonic guidance for the treatment of upper urinary calculus. Methods From June 2004 to July 2009, 1289 patients with upper urinary tract calculi were treated with PCNL under ultrasonic guidance, 386 cases of them were upper ureteral calculi, 463 cases were single renal calculi,355 cases were multiple renal caculi, 85 cases were staghorn calculi. Calculus size was 0.8 cm× 1.2cm-9.0 cm× 5.3 cm,mean 2. 1 cm× 3.1 cm. Nine hunderd and thirty-five cases were with hydronephrosis. Results All patients were performed PCNL successfully, without conversion to open surgery or death. Mean operation time was 90(55-220)min, mean operative blood loss was 175(60-800)ml. Thirty-one cases were given blood transfusion during operation or post operation, 14 cases were given super-selective renal artery embolism for bleeding control. 1105 cases were treated with single tract, 108 cases with double tracts, 76 cases with three tracts. Calculus clearance rate of onestage PCNL was 85.03%(1096/1289);193 cases were found with residual calculi, 67 of them were given extracorporeal shock-wave lithotripsy, 126 of them were given two-stage PCNL, calculi were removed complelety in 85 cases. Total calculus clearance rate was 91.62%(1181/1289). Conclusions PCNL under ultrasonic guidance is an effective and safe method for the treatment of upper urinary calculus with advantages of accurate positioning, high calculus clearance rate, minimal trauma, and fewer complications. The key of successful PCNL is selection of patients, grasp of operation technique, and availability of other equipements.
