目的:探讨经皮肾镜气压弹道联合超声碎石清石术治疗肾结石的临床疗效和安全性。方法:对2012年1月~12月间我院收治的42例肾结石患者采用经皮肾镜(PCNL)气压弹道联合超声碎石系统进行治疗,与同期行经皮肾穿刺气压弹道取石术治疗的40例患者的临床资料进行比较,比较2组的治疗效果和安全性。结果:2组患者术中失血分别为75.6±10.3ml和128.4±18.8ml,差异有统计学意义(p<0.05);平均手术时间分别为80.5±10.8分钟和145.2±20.1分钟,差异有统计学意义(p<0.05);1期结石清除率分别为92.9%(39/42)和62.5%(25/40),差异有统计学意义(p<0.05)。结论:在不改变治疗安全性的前提下,经皮肾镜气压弹道联合超声碎石清石术治疗肾结石可明显减少术中出血和手术时间,提高结石的清除率,效果显著,值得临床推广。
Objective: To investigate the clinical efficacy and safety of percutaneous nephrolithotomy combined with ultrasonic lithotripsy in the treatment of renal calculus. Methods: Forty-two patients with nephrolithiasis admitted to our hospital from January to December in 2012 were treated with PCNL pneumatic lithotripsy and ultrasonic lithotripsy. In the same period, percutaneous nephrostomy and pneumatic lithotripsy were performed The clinical data of 40 patients were compared and the treatment effect and safety of the two groups were compared. Results: The blood loss of the two groups were 75.6 ± 10.3ml and 128.4 ± 18.8ml respectively (p <0.05). The mean operation time was 80.5 ± 10.8 minutes and 145.2 ± 20.1 minutes respectively, the difference was statistically significant (P <0.05). The stone clearance rate of stage I was 92.9% (39/42) and 62.5% (25/40), respectively, with significant difference (p <0.05). CONCLUSION: Percutaneous nephrolithotomy combined with ultrasonic lithotripsy and lithotripsy for renal calculus can significantly reduce intraoperative bleeding and operation time and improve the clearance rate of stones, which is worthy of clinical promotion without changing the treatment safety .
