查询词典 shock wave

Methods 82 cases suffered from multiple stones in homolateral ureter were divided into 2 groups and treated by ESWL with home made JDPN-V B model extraocorperedl shock wave lithotripter under X-ray positioning. Experimental group was under the sequence of distal first proximal later and confrol group was under the different sequence.

方法对82例同侧输尿管内多发结石患者进行分组，应用国产JDPN-V B型体外冲击波碎石机ESWL治疗，X线定位，对照组采取先治疗近端后治疗远端的治疗顺序；实验组采取先远端后近端的治疗顺序。
