目的 探讨经皮肾微造瘘输尿管镜治疗肾结石的安全性和有效性。方法 对 4 0例肾结石患者进行经皮肾微造瘘输尿管镜气压弹道碎石及取石术。结果 2 5例患者行一期穿刺取石 ,15例患者行二期穿刺取石 ,单通道穿刺取石 18侧肾 ,二通道穿刺取石 2 2侧肾 ,结石清除率 89 12 % ,平均手术时间 10 0min ,肾造瘘留置时间平均 7d ,平均住院时间 14d ,其中 1例需要输血 ,未出现大的并发症。结论 经皮肾微造瘘输尿管镜一期取石治疗肾结石是有效和安全的 ,具有创伤小、结石清除率高、恢复快、住院时间短等优点
Objective To investigate the safety and efficacy of ureteroscopic percutaneous nephrostomy in the treatment of renal calculus. Methods Percutaneous nephrostomy with ureteroscopic pneumatic lithotripsy and lithotripsy were performed in 40 patients with renal stone. Results Twenty-five patients underwent primary percutaneous puncturation. Fifteen patients underwent second-stage puncture, single-pass puncture and 18 lateral nephrolithotomy, two-pass puncture and two-two side nephrostomy. The stone clearance rate was 89.12% and the average operation time was 10 minutes. Nephrostomy indwelling time averaging 7d, the average length of stay 14d, of which 1 required blood transfusions, no major complications. Conclusions Percutaneous nephrostomy ureteroscopy with primary stone lithotripsy is effective and safe, has the advantages of small trauma, high rate of stone clearance, quick recovery and short hospital stay
