目的:探讨彩色多普勒(CDFI)超声对输尿管结石的诊断价值。方法:回顾160例输尿管结石病例,经CDFI检测输尿管结石周边尿流变化及输尿管开口喷尿情况的变化,确定结石的存在。结果:上段结石78例。中段20例,下段62例,结石周边尿流出现五彩镶嵌彩色信号,且输尿管开口喷尿出现异常。结论:CDFI对输尿管结石诊断率高,重复性好,无痛苦,可作为输尿管结石的首选检查方法。
Objective: To investigate the diagnostic value of color Doppler ultrasound (CDFI) in the diagnosis of ureteral calculi. Methods: 160 cases of ureteral calculi were retrospectively analyzed. The changes of urinary flow around the ureteral calculi and the ureteric ureter were detected by CDFI to determine the presence of stones. Results: 78 cases of upper stones. 20 cases in the middle and 62 cases in the lower part. The multicolored mosaic color signals appeared in the urine flow around the calculus, and the ureteropelvicuria was abnormal. Conclusion: CDFI has high diagnostic rate and good reproducibility for ureteral calculi. It can be used as the first choice of ureteral calculi.
