低能量长间距体外冲击波碎石(附380例报告)

Technique report on the application and research of low energy and long-ditance shock wave by extracorporeal shock wave lithotripsy(Report of 380 cases)

目的 :探讨低能量、长间距冲击波技术在体外冲击波碎石 (ESWL)中的应用 ,以及 X线、B超双定位技术在 ESWL中的优势。方法 :应用低能量、长间距冲击波及 X线、B超双定位技术进行 ESWL380例。结果 :380例均获成功 ,结石排净或残石颗粒直径均 <3mm。所有患者术后都出现轻微血尿 ,肾结石者 1 2 h内消失 ,输尿管结石者 1～ 2次后消失。 58例局部皮肤出现点状红斑。1 1例形成输尿管石街 ,经再次 ESWL治疗而消失。肾被膜下血肿 1例 ,经对症处理 2周后血肿被吸收。结论 :低能量、长间距冲击波技术碎石率高 ,具有血尿时间短、无输尿管绞痛发作、肾被膜血肿发生率低等优点。 X线、B超双定位技术值得推广。

Purpose:Through the application and research of the technique low energy and long-distance shock wave by extracorporeal shock wave lithotripsy(ESWL)we intend to explore its application skills,advantage of X-ray or B-mode ultrasonic examination in determining the location.Methods:We used the technique of low energy,long-distance shock wave and X-ray or B-mode ultrasonic examination in determining the location to treat 380 patients who suffered from calculus disease.Results:The 380 cases which we performed turned out to be very successful.The technique of therapy with low energy,long-distance shock wave has greatly raised the cure rate of calculosis.It has a superiority with short time of hematuria,no ureteralgia and lower the occurrence rate of kidney film hematoma.Conclusion:ESWL provides a new therapy to treat calculus disease.The technique of low energy and long-distance shock wave has great practical value,and the technique of X-ray or B-mode ultrasonic examination in determining the location of calculus is well worth spreading.
