体外冲击波碎石(ESWL)可使大多数输尿管结石行原位碎石治疗即可获得满意疗效。但临床工作中发现对一部分无症状输尿管结石直接行原位ESWL治疗效果并不理想,于是,我们首先通过对输尿管置人支架管使结石移位,即ESWL术前置输尿管支架管改变结石的位置,然后,再行ESWL治疗无症状输尿管结石。该综合疗法经过临床观 Extracorporeal shock wave lithotripsy (ESWL) can make most of the ureteral stones in situ gravel treatment to obtain satisfactory results. However, clinical work found that part of asymptomatic ureteral stones direct ESWL treatment in situ is not satisfactory, so we first place the ureteral calcification tube stent placement, which ESWL preoperative ureteral stent to change the location of stones , And then ESWL treatment of asymptomatic ureteral stones. The comprehensive treatment through clinical observation
