目的探讨微创经皮肾镜取石术(MPCNL)治疗上尿路结石的安全性及有效性。方法对420例接受MPCNL治疗的上尿路结石患者的临床资料进行了回顾性分析。结果所有患者均行一期穿刺取石术,其中单通道取石393例,双通道取石27例,结石清除率91.66%。平均手术时间105min,肾造瘘管留置时间平均7d,平均住院时间13d,术中输血8例,无严重并发症发生。结论 MPCNL治疗上尿路结石具有安全、有效、结石清除率高、创伤小、恢复快、住院时间短等特点,值得临床推广应用。
Objective To investigate the safety and efficacy of minimally invasive percutaneous nephrolithotomy (MPCNL) in the treatment of upper urinary tract calculi. Methods The clinical data of 420 patients with upper urinary tract stones treated with MPCNL were retrospectively analyzed. Results All the patients underwent primary puncture and lithotomy. There were 393 cases of single-channel stone removal, 27 cases of double-channel stone removal and 91.66% of stone clearance. The average operation time was 105 minutes, the average length of renal fistula indwelling time was 7 days, the average length of hospital stay was 13 days, and intraoperative blood transfusion was performed in 8 cases. No serious complications occurred. Conclusion The treatment of upper urinary calculi with MPCNL is safe, effective, high rate of stone removal, small trauma, quick recovery and short hospital stay, which is worthy of clinical application.
