目的 :探讨复式脉冲HB V型低能量体外冲击波碎石机治疗肾结石的治疗效果。方法 :采用复式脉冲HB ESWL -VG型低能量碎石机治疗直径 <2 .0cm的各类肾结石 76 9例 ,治疗工作电压 3～ 9kV ,平均冲击次数 2 30 0次。结果 :肾盏结石总粉碎率为 97.4 % ,其中上中盏结石复打率为 13.1% ,术后 3个月排净率为 89.4 % ,下盏结石复打率为 17.3% ,排净率为 81.5 % ;肾盂结石粉碎率为 98.3% ,复打率为 6 .1% ,术后 3个月排净率为93.0 %。结论 :复式脉冲低能量ESWL治疗肾结石具有治疗成功率高、复打率低、无严重并发症、副作用少之优点。
Objective: To investigate the therapeutic effect of double pulse HB V low energy extracorporeal shock wave lithotripsy on renal calculus. Methods: 769 cases of various types of kidney stones of diameter <2.0 cm were treated with double pulse HB ESWL -VG low energy lithotripsy machine. The working voltage was 3 ~ 9 kV and the average number of impact was 2 30 0. Results: The total crushing rate of calyceal calculus was 97.4%, of which the upper calyceal calculus was 13.1%. The net calming rate was 89.4% at 3 months and 17.3% ; Pelvis stone crushing rate was 98.3%, the repeat rate was 6.1%, three months after the draining rate was 93.0%. Conclusions: Double pulse ESWL with low energy ESWL treatment has the advantages of high success rate, low repetition rate, no serious complications and few side effects.
