目的探讨B超引导建立皮肤-肾脏通道(皮肾通道),在经皮肾镜联合钬激光治疗肾结石的临床疗效和安全性。方法回顾性分析247例采用B超引导穿刺建立经皮肾通道,行经皮肾镜联合钬激光治疗的肾结石患者临床资料。结果238例患者1次成功建立皮肾通道;240例行1期碎石术,7例行2期碎石术;碎石手术时间65～167min。5例患者术中输血200～800mL,无气胸、损伤腹腔脏器等严重并发症发生。术后5d复查,218例患者结石清除干净,29例有结石残余,结石清除率为88.3%(218/247)。结论采用B超引导穿刺建立皮肾通道经皮肾镜碎石术治疗肾结石安全、可靠。
Objective To investigate the clinical efficacy and safety of B-ultrasound guided skin-kidney channel (PFN) in the treatment of renal calculi with percutaneous nephrolithotomy and holmium laser. Methods The clinical data of 247 renal calculi patients who underwent percutaneous nephrolithotomy combined with holmium laser were retrospectively analyzed. Results A total of 238 patients underwent primary renal allografting successfully. One of 240 patients underwent primary lithotripsy and 7 patients underwent secondary lithotripsy. The operation time of gravel was 65 to 167 minutes. Five patients with intraoperative blood transfusion 200 ~ 800mL, no pneumothorax, abdominal injury and other serious complications occurred. Five days after the operation, 218 patients had clear stones, 29 had residual stones, and the stone clearance rate was 88.3% (218/247). Conclusion B-ultrasonography guided percutaneous nephrolithotripsy is a safe and reliable method for the treatment of renal calculi.
