复式脉冲碎石机治疗儿童上尿路结石

目的探讨低能量复式脉冲碎石机对儿童上尿路结石治疗的可行性。方法采用国产BH-VG低能量复式脉冲碎石机治疗儿童上尿路结石21例，男童11例，女童10例；学龄前儿童（2-7岁）13例；学龄期儿童（8-16岁）8例。肾结石每次治疗不超过2500次，治疗电压3-7．5kV；输尿管结石每次治疗不超过3500次，治疗电压4-8kV。结果肾结石粉碎率100％，两周内结石排空率100％；输尿管结石粉碎率100％，两周内结石排空率100％。结论低能量复式脉冲碎石机治疗儿童上尿路结石是一种安全、有效的治疗方法。

Treatment of pediatric upper urinary calculi with twin pulse low-energy ESWL

Objective To evaluate the safety and efficacy of twin pulse low-energy ESWL in the treatment of pediatric upper urinary calculi. Methods A total of 21 cases of pediatric upper urinary calculi were treated with twin pulse low-energy ESWL（HB-VG）, including 11 boys and 10 girls, The children＇s age ranged from 2 to 16 years old, 13 below 7 years old and 8 from 8 to 16 years old. The treatment voltage was 3 to 7.5 kV for renal calculi, and the number of impulse was limited to below 2 500. The treatment voltage was 4 to 8 kV for ureteral calculi, and the number of impulse was limited to below 3 500. Results Both the stone fragmentation rate and the stone-free rate two weeks after the ESWL treatment were 100%, and no severe complications were noted. Conclusion The twin pulse low-energy ESWL is a safe and effective treatment for patients with upper urinary calculi.
