目的 探讨电磁波碎石对不同部位不同成分泌尿系结石的疗效。方法 选择 4 34例泌尿系结石的病人 ,分肾盂、肾盏、输尿管、膀胱四组 ,行电磁波碎石 ,2个月后复查结石排尽情况并算出结石排尽率 ,并将肾盂结石组记录结石击碎所需的累计能量 ,排出的碎石作结石成分分析。结果 各组碎石后结石排尽率明显不同 ,肾盏 88 4 % ,肾盂 96 3% ,输尿管 84 8% ,膀胱 91 2 % ,P <0 0 5。肾盂组各成分结石击碎所需的平均能量不同 ,草酸钙 >磷酸钙 >尿酸盐 >磷酸镁胺 ,P <0 0 5。结论 电磁波碎石对不同部位、不同成分的泌尿系结石均有较好疗效 ,但不同部位、不同成分的结石疗效有明显差异 ,临床应用电磁波碎石时应综合分析 ,提高疗效。
Objective To investigate the curative effect of electromagnetism lithotripsy on different components of urinary calculi. Methods Four hundred and seventy-four patients with urolithiasis were divided into four groups: the renal pelvis, the calyceal tube, the ureter and the urinary bladder. Electromagnetic wave lithotripsy was performed. After 2 months, the stones were discharged and the rate of stone drainage was calculated. The pelvis group The total energy required for stone crushing, stone discharge as a component analysis. Results The numbers of post-gravel stone drainage were significantly different in all groups. 88 4% of calculus, 96 3% of renal pelvis, 84 8% of ureter, 91 2% of bladder, P <0.05. The average energy required for crushing stones in the pelvis group was different, calcium oxalate> calcium phosphate> urate> magnesium phosphate amine, P <0 05. Conclusion Electromagnetic wave lithotripsy has a good curative effect on urolithiasis of different parts and components, but there are significant differences in curative effect between different parts and different components. The clinical application of electromagnetic wave lithotripsy should be comprehensively analyzed to improve curative effect.
