目的使用利尿加压法以提高超声对输尿管结石的检出率。方法72例均行口服速尿后饮水并腹部加压,以增强超声对各段输尿管结石显像。结果输尿管腹段、第二狭窄、盆段、第三狭窄处结石检出率由常规超声的65%、50%、31%、32%分别提高到97%、100%、88%、100%,总检出率96%,同期X线肾盂静脉造影检出率为94%。结论使用利尿加压法显著提高了超声对于各段输尿管结石的检出率,较X线肾盂静脉造影检出率略高,值得推广。
Objective To improve the detection rate of ureteral calculi by using diuretic pressure method. Methods All 72 patients underwent oral administration of furosemide and abdominal pressure to enhance ultrasound imaging of ureteral stones. Results The detection rate of stones in the ureter abdominal segment, the second stenosis, the pelvic segment and the third stenosis increased from 65%, 50%, 31% and 32% to 97%, 100%, 88% and 100% The total detection rate of 96%, over the same period X-ray renal pelvisography was 94%. Conclusion The use of diuretic pressure method significantly increased the detection rate of ureteral stones for each segment of ultrasound, slightly higher than the rate of X-ray renal pelvic vein imaging rate, it is worth promoting.
