超声引导下穿刺在经皮肾镜碎石及清石术中的应用

Application of ultrasound-guided technique in percutaneous nephrolithotomy and in pneumatic lithotripsy

目的探讨超声引导下穿刺在经皮肾镜碎石及清石术中的应用价值。方法在超声引导下经皮穿刺患有肾脏结石的积液肾盏,根据结石所在部位不同,分别穿刺上、中、下盏。结果所有患者均穿刺成功,其中32例1次成功,占94%。碎石清石术后1个月经B超复查,32例肾内无结石显示,有2例患者肾内残留有1～2枚直径<10 mm的较小结石。结论超声引导下经皮肾镜穿刺定位准确、操作方便、穿刺成功率高,能在不影响手术的情况下指导取石,缩短了取石时间,提高了取石的成功率。

Objective To study the use of ultrasound for renal lithotripsy percutaneously. Methods To puncture kidney percutaneously guided under B ultrasound to remove calculus in renal calyces. The upper, middle and lower calyces were being punctured based on the location of calculus in the kidney. Results Of 34 cases, all were well performed and 94% of the cases were successful with one pucture. One month after procedure,32 patients were calculus-free and 2 patients still carried smaller calculis（〈10 mm）. Conclusion Ultrasound guiding lithotripsy is a precise and convenient procedure with high success rate,providing a harmless and safe treatment for patients with nephrolithiasis.
