摘要: 目的:研究斜仰卧-截石位双镜联合(肾镜联合顺-逆行输尿管软镜)治疗复杂性肾结石的疗效和安全性。方法:回顾性分析我院使用斜仰卧-截石位双镜联合治疗的76例复杂性肾结石患者资料,观察碎石、取石效果。结果:69例患者一期手术中双镜联合治疗肾结石(69例均使用顺行输尿管软镜碎石,其中23例顺行输尿管软镜碎石后同期逆行输尿管软镜治疗残留结石),7例二期手术中双镜联合治疗结石。一期手术时间65133min,平均(95.66±15.21) min,结石清除率为90.7%(69/76);二期手术时间55~106min,平均(73.26±11.33) min,结石清除率96.1%(73/76)。3例患者二期手术后仍有残留结石,术后1个月行体外冲击波碎石术(ESWL)治疗,1例结石完全排出,2例残留结石直径大小0.60.9cm。结论:斜仰卧-截石位双镜联合治疗复杂性肾结石安全、迅速,一期手术结石清除率高,患者术后恢复快,是一种安全有效的治疗复杂性肾结石的方法。Abstract: Objective:To investigate the safety and effect of combined endoscopy (standard-access percutaneous nephrolithotomy in oblique supine lithotomy position combined with prograde or retrograde flexible ureteroscopy) in treatment of complex renal calculi.Method:We observed the curative effect from retrospective analysis data of 76 patients with complex renal calculi in our department who were treated by oblique supine combined endoscopy.Result:Sixty-nine cases treated with PCNL combined with prograde flexible ureteroscopy in first-stage operation, including 23 cases with retrograde flexible ureteroscopy at the same time.Seven cases treated with PCNL combined with flexible ureteroscopy in second-stage operation.The time of first-stage operation ranged from65 to 133 min (average, 95.66±15.21 min), stone clearance rate was 90.7% (69/76), The time of second-stage was from 55 to 106 min (average, 73.26±11.33 min), stone clearance rate was 96.1% (73/76).Three cases had remained stone after second-stage operation.Residual calculus of one case was removed completely by ESWL one month later, and the diameter of residual calculus of the two cases was 0.6-0.9 cm.Conclusion:Combined endoscopy in oblique supine lithotomy position is a safe and effective operation method with high stone clearance rate and quick recovery for complex renal calculi.
