超声诊断输尿管结石

目的探讨提高超声诊断输尿管结石的方法.方法对207例输尿管上段、中段及下段结石患者,采用不同的超声检查体位和方法,重点扫查中、下段输尿管,并对显示不清的中、下段输尿管结石,在患者口服超声膀胱快速显像剂后,采用绷带棒加血压带气囊加压法再行扫查.结果超声检查直接显示上段输尿管结石68例,准确率为100%;中段输尿管结石93例,准确率98%(93/95);下段输尿管结石43例,准确率98%(43/44).结论口服超声膀胱快速显像剂后,采用绷带棒加血压带气囊加压法可提高超声对中、下段输尿管结石的诊断率,是一种有价值的检查方法.

Study on the methodology of diagnosis of ureteral calculi by ultrasonography

Objective To evaluate the improvement in the diagnostic accuracy of ureteral calculi by ultrasonography. Methods The upper,middle and lower parts of ureters of 207 patients with ureteral calculi were detected by ultrasound in varied postures and methods. During examination the emphasis was put on the middle and lower parts of the ureter. For unclear images of middle and lower ureteral calculi, the oral rapid developer for cystodiaphanoscopy was taken by the patients and bandage stick adding balloon of sphygmoma-nometer belt pressure check-up was applied for re-examination. Results With these methods, the accuracy of ultrasonic diagnosis was 100% in 68 cases of the upper ureteral calculi, 98% in 95 cases of the middle ureteral calculi (93/95) and 98% in 44 cases of the lower ureteral calculi (43/44) , respectively. Conclusions By means of these methods, the ureteral calculi can be well displayed, and the ultrasonographic diagnostic accuracy can be improved. They are valuable methods for detecting ureteral calculi.
