超声引导在经皮肾镜取石术中的应用价值

目的探讨超声引导在经皮肾镜取石术中的应用价值。方法对287例肾结石患者行超声引导经皮肾穿刺，建立皮肤肾脏通道，进行肾镜下取石术。结果287例患者共穿刺肾脏315个，每个肾脏穿刺（1．19±0．58）次，一次穿刺成功260个肾脏，一次性成功率为82．5％；二次穿刺成功51个肾脏，占16．2％，二次性成功率为98．7％；三次穿刺成功4个肾脏，占1．3％，三次性成功率为100％。均一期建立皮肤肾脏通道。结论超声引导建立皮肤肾脏通道准确、方便、安全，具有重要的临床应用价值。

Applicable Value of Ultrasound Guidance in Percutaneous Nephrostolithotomy

Objective To explore the applicable value of ultrasound guidance in percutaneous nephrostolithotomy. Methods 287 patients with renal calculi received ultrasound-guided percutaneous renal puncture to develop renal tract for percutaneous nephrostolithotomy. Results 315 kidneys（among 287 patients） were punctured under ultrasound guidance, one kidney was punctured（ 1.19 ± 0.58） times averagely. 260 kidneys were punctured successfully after one time,the successive rate of single puncture was 82.5% ,51 kidneys （16.2%） were punctured successfully after twice treatment, the successive rate of two-times puncture was 98.7% ,4 kidneys （1.3%） were punctured successfully after thyee times,the successive rate of three-times puncture was 100%. Renal tract was developed at 1 session in every case under ultrasound guidance. Conclusion Ultrasound guidance is an accurate,convenient and safe method to develop renal tract for percutaneous nephros- tolithotomy. It has an important practical clinical value.
