We have undertaken extracorporeal shock wave lithotripsy (ESWL) using the second generation lithotripter, Sonolith 2000. Shock waves are generated by an underwater spark gap discharge and stone localization is performed using an ultrasound scanner. A total of 49 treatments were given to 39 patients with upper urinary tract calculi. Twenty one patients (56.8%, 21/37) were completely free of stones and seven patients (18.9%, 7/37) had residual sandy particles on the 42nd day after ESWL. Seven patients (18.9%, 7/37) had residual fragments less 5 mm in diameter and two patients (5.4%, 2/37) had residual fragments exceeding 6 mm in diameter six weeks after ESWL. Two patients were lost to follow-up. There was a strong correlation between the stone free rate and stone size. Almost all stone of more than 25-30 mm in diameter required more than one session. There were no severe complications during and after ESWL.
我们使用第二代碎石机Sonolith 2000进行了体外冲击波碎石术（ESWL）。冲击波由水下火花隙放电产生，结石定位通过超声扫描仪进行。对39例上尿路结石患者共进行了49次治疗。在ESWL治疗后第42天，21例患者（56.8%，21/37）结石完全清除，7例患者（18.9%，7/37）有残余沙粒样结石。在ESWL治疗六周后，7例患者（18.9%，7/37）有直径小于5mm的残余结石碎片，2例患者（5.4%，2/37）有直径超过6mm的残余结石碎片。2例患者失访。结石清除率与结石大小密切相关。几乎所有直径超过25 - 30mm的结石都需要进行不止一次治疗。ESWL治疗期间及治疗后均未出现严重并发症。
