B超引导下经皮肾镜超声联合气压弹道碎石清石术60例

Percutaneous nephrolithotripsy with ultrasonic and pneunmtic lithotripter for renal calculunder the guidance of B - ultrasound（ report of 60 cases）

目的探讨经皮肾镜超声联合气压弹道碎石术治疗肾结石的方法与安全性。方法回顾性分析采用经皮肾镜结合EMSm代气压弹道、超声碎石清石机治疗60例肾结石患者的临床资料。结果该组60例，肾结石一次取净55例，取净率91．7％，5例残留肾盏小结石均〈1．0cm，经体外震波碎石后自行排出。平均手术时间1．1h；平均住院时间10．2d。结论经皮肾镜配合气压弹道超声碎石机治疗肾结石具有明显优势，创伤小，在碎石的同时可以通过碎石机的超声负压吸引装置一期将结石吸出，取石效率大大提高。

Objective To investigate the approach and safety of percutaneous nephrolithotripsy with ultrasonic and pneumatic lithotripter for renal calculi. Methods Sixty patients underwent pereutaneous nephrolithotripsy using an EMS Ⅲ pneumatic and ultrasonic lithotripter. Clinical data were analyzed retrospectively. Results Sixty cases in this group, the stones were cleared of in 55 of the 60 cases after the 1st session, the stone - free rate was 91.7% ,only 5 cases of relict little stones in the lower renal calyx were treated by ESWL for the second time and then cleared of. The average operative time was 1.1 hours,average hospitalization being 10. 2 days. Conclusions Treatment of complex renal calculi with PCNL associated by pneumatic and ultrasound lithotripsy has obvious advantages ,less invasion, stones can cleared of by the ultrasound equipment with subpressure simuhaneously,the efieieney of stone-flee is much increased ,and the method of treatment is worthy of popularization.
