B超X线联合引导下微创经皮肾镜治疗无积水肾铸型结石

Minimally lnvasive percutaneous nephrostolithotomy for non-hydrocele staghorn calculi under the guidance of B -mode ultrasound combined with radiography

目的 探讨B超、X线联合引导下，应用微通道经皮肾镜技术治疗无积水的肾铸型结石的临床意义。方法 对24例无积水的肾铸型结石患者，在B超和X线C臂机联合定位引导下，建立微创工作通道行经皮肾镜一期取石。结果均准确建立理想的穿刺、工作通道，结石临床清除率87．5％，24例患者均未出现严重并发症。结论 B超和X线联合引导下经皮肾镜技术治疗无积水的铸型肾结石，既可提高工作通道建立的准确性及安全性，增加手术的成功率，又在一定程度上减少了术中的辐射损伤，临床效果理想。

Objective To investigate the value of minimally invasive percutaneous nephrostolithotomy （ MPCNL ） for non-hydrocele staghorn calculi under the guidance of B-mode ultrasound combined with radiography. Methods Twenty-four cases of non-hydrocele staghorn calculi underwent one-stage MPCNL under the guidance of B- mode ultrasound combined with C-model arm X-rays machine. Results Precise operative tract was established in all cases. The stone-free rate amounted to 91.7%. No case experienced severe complications. Conclusion MPCNL under the guidance of B-mode ultrasound combined with radiography can improve the precision and safety in establishing the operative tract, increase the success rate of operation, and decrease the amount of radiation in the treatment of non-hydrocele staghorn calculi.
