电磁波碎石对不同部位不同成分泌尿系结石的疗效观察

Curative effect of electromagnetic wave lithotrity on calculis in different parts with different composition of the urinary system

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 effect of the electromagnetic wave lithotrity on the calculis in different parts with different composition of the wrinary system.Methods Electromagnetic wave lithotriotces were performed on 434 inpatients of urinary system including renal pelvis(RP),renal calices(RC),ureter and bladder 4 groups.After 2 months we checked the dischargement of calculis and got the rates of it.We analyzed the total energy needed by crushing the calculis and their composition.Results The rates of dischargement of calculis were obviously different between RC(88.4%),RP(96.3%),ureter(84.8%) and bladder( 91.2%)(P<0.05).The average energy needed in different calculis were also different with oxalate>calcium phosphate>uric acid>stravite(P<0.05).Conclusion Electromagnetic wave has better effect on crashing calculis in different parts with different composition of the urinary system.But the curative effects of them are tangibly different.Clinical application of electromagnetic wave lithotrity should take into account of all related factors so as to improve the effect.
