目的:探讨C臂X线机联合B超在经皮肾镜碎石术治疗复杂肾结石中的安全性、实用性及其临床价值。方法:回顾性分析2009年6月~2012年6月采用C臂X线机联合B超引导下行经皮肾镜碎石术治疗复杂性肾结石患者206例的临床资料,对患者手术时间、输血率、结石Ⅰ期清除率、术中术后并发症等进行分析。结果:206例均在C臂X线机联合B超引导下准确建立理想的工作通道;平均手术时间74min。术中术后输血率13.5%(28/206);结石一期清除率为92.2%(190/206);术后行二期碎石术或ESWL治疗者占7.8%(16/206)。结论:采用C臂X线机联合B超引导下经皮肾镜碎石术治疗复杂性肾结石是安全、实用、高效的手段,结石Ⅰ期清除率高,且术中术后并发症少。
Objective: To investigate the safety, practicability and clinical value of C-arm X-ray combined with B-mode ultrasonography in the treatment of complex renal calculi. Methods: The clinical data of 206 patients with complicated renal calculi treated with C-arm X-ray and B-guided percutaneous nephrolithotomy were retrospectively analyzed from June 2009 to June 2012. The operative time, blood transfusion Rate, stage Ⅰ clearance rate, intraoperative and postoperative complications were analyzed. Results: All 206 patients underwent accurate C-arm X-ray and B-ultrasound guidance and established an ideal working channel. The average operation time was 74 min. The intraoperative blood transfusion rate was 13.5% (28/206). The first stage stone clearance rate was 92.2% (190/206). The second stage stone surgery or ESWL treatment accounted for 7.8% (16/206). Conclusion: C-arm X-ray combined with B-guided percutaneous nephrolithotripsy is a safe, practical and effective method for the treatment of complicated renal calculi. The rate of stage Ⅰ stone removal is high and there are few postoperative complications.
