X线与B超定位行经皮肾镜气压弹道碎石的疗效比较

Comparison of the efficancy of established access under the guidance of B-ultrasound and radiography in percutaneous nephrolithotomy

目的比较在经皮肾镜取石术(PCNL)中X线与B超引导建立经皮肾道的效果。方法对68例肾结石患者,分别采取C臂X线机和B超引导建立经皮肾通道,其中采取C臂X线机引导组30例,B超引导组38例。结果X线引导组建立通道时间平均为8.6 min,并发症发生率为3.3%,残余结石发生率6.6%。B超引导组为穿刺时间3.2 min,并发症2.6%,残余结石5.3%,两组均无大出血。结论两种方法各有优缺点,可根据患者具体情况和术者的习惯进行选择。

Objective To compare of the efficancy of established percutaneous access under the guidance of B-ultrasound and the portable fluoroscopic imaging system. Methods 68 cases of renal calculi underwent PCNL under the guidance of B-uhrasound and the portable flouroscopic imaging system,30cases were guided by the portable flouroscopic imaging system,the others by B-ultrasound. Results In the portable flouroscopic imaging system group, the operative time was 8.6minutes, operative complications rate was 3.3 %, the rate of residual stone was 6.6%, while the B-ultrasound group was 3.2 minutes and 2.6%, and 5.3%. Conclusion The different way can be used for patients and operators in accordance with the different situation.
