1989年4月至1992年4月,我们应用BD8828型碎石机作体外震波碎石术(ESWL)治疗泌尿系结石385例,其中巨大肾结石92例(巨大肾结石指×线及B超检查,计算总面积达9cm~2以上的单发结石、多发结石及鹿角形结石),占23.6％,现报告如下。 临床资料 1.一般资料:本组患者男性68例,女性24例。年龄12～75岁。最大的肾盂、肾盏完全性铸形结石面积达29.82 cm~2(7.1 cm×4.2 cm)。双肾大面积结石2例,对侧肾合并小结石20例。共碎石94侧。术前IVP提示患肾功能均存在,血BUN、Cr在正常范围。 2.治疗方法:碎石前肌注度冷丁75mg及安定10mg。仰卧位,B超定位。先从肾盂、输尿管交界处开始碎石,逐渐移至肾上盏、肾中盏、肾下盏。工作电压11.2～12kV,每次治疗冲击频率不超过2400次。碎石最少1次,最多7次,平均3.17次。
April 1989 to April 1992, we use BD8828 lithotripsy for extracorporeal shock wave lithotripsy (ESWL) for the treatment of 385 cases of urinary stones, of which 92 cases of huge kidney stones (huge kidney stones × line and B-ultrasound , Calculated a total area of 9cm ~ 2 more than a single stone, multiple stones and antlers stone), accounting for 23.6%, are as follows. Clinical data 1. General information: 68 patients in this group of males and 24 females. Aged 12 to 75 years old. The largest renal pelvis, calyx complete cast stone area of 29.82 cm 2 (7.1 cm × 4.2 cm). Large kidney stones in 2 cases, contralateral kidney combined with small stones in 20 cases. Common gravel 94 side. Preoperative IVP prompted renal function exist, blood BUN, Cr in the normal range. 2. Treatment: anterior derma grading Miltiorrhiza 75mg and stability 10mg. Supine position, B-positioning. First from the renal pelvis, ureter junction at the beginning of gravel, and gradually moved to the upper kidney, kidney in the lamp, the next lamp. Working voltage 11.2 ~ 12kV, each treatment impact frequency does not exceed 2400 times. Gravel at least 1 times, up to 7 times, an average of 3.17 times.
