目的评价经皮肾镜超声气压弹道碎石术治疗肾结石的安全性与疗效。方法肾结石498例,采用第四代EMS超声气压弹道碎石清石系统治疗肾结石,术后5 d复查腹部平片了解结石清除情况,观察手术的疗效及并发症。结果 498例均一期建立经皮肾通道并碎石,平均手术时间54 min,术后平均住院时间6.2 d,肾结石取净率为92.7%。术后18例行体外冲击波碎石,18例2期经皮肾镜取石术(PCNL)后结石取净率为96.4%。结论经皮肾镜应用超声气压弹道碎石术治疗肾结石,具有效高率、微创、安全等特点。
Objective To evaluate the safety and efficacy of percutaneous nephrolithotopic pneumatic lithotripsy in the treatment of kidney stones. Methods A total of 498 cases of renal calculi were treated with the fourth generation of EMS pneumatic lithotripsy lithotripsy for the treatment of kidney stones. Five days after the operation, abdominal plain films were reviewed for stone removal and the curative effect and complications of the operation were observed. Results In 498 cases, the percutaneous renal access and gravel were all established in one phase. The average operation time was 54 min. The average postoperative hospital stay was 6.2 days. The net acquisition rate of kidney stones was 92.7%. 18 cases of extracorporeal shock wave lithotripsy, 18 cases of 2 stage percutaneous nephrolithotomy (PCNL) after the stone removal rate was 96.4%. Conclusion Percutaneous nephrolithotomy using ultrasonic pneumatic lithotripsy for the treatment of kidney stones with high efficiency, minimally invasive, safe and so on.
