目的研究超声伪像中的声影、彗尾征在尿结石超声影像检查中的意义。方法对238例尿石症患者的尿结石成分、大小及超声检查时声影、彗尾征出现情况进行统计学评估,分析其相关性。结果 (1)声影的出现与尿结石成分无关(P>0.05);(2)声影与结石最大厚度有关(P<0.05),而声影与结石最大宽度无关(P>0.05);(3)彗尾征与结石的最大宽度及最大厚度均无关(P>0.05)。结论 (1)声影的出现与尿结石的成分无关,不能用于判定结石成分;(2)声影的出现与尿结石的厚度有直接的关系,但彗尾征的出现与尿结石的厚度和宽度无关。
Objective To study the significance of acoustic shadow and coma tail in ultrasound imaging of urolithiasis. Methods Urine calculi of 238 patients with urolithiasis, size and sonographic ultrasound findings, the occurrence of tail-like symptoms were statistically assessed and analyzed its relevance. Results: (1) The appearance of sound shadow was not related to the composition of urinary stones (P> 0.05); (2) the sound shadow was related to the maximum thickness of stone (P <0.05) 3) There was no correlation between tail tip and the maximum width and maximum thickness of stone (P> 0.05). Conclusions (1) The appearance of sound and shadow has nothing to do with the composition of urinary stones, can not be used to determine the composition of stones; (2) the appearance of acoustic shadow and the thickness of urinary stones have a direct relationship, but the appearance of comet tail signs and urinary calculus thickness Has nothing to do with width.
