摘　　要：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 evaluate the significance of acoustic shadowing and comet tail artifacts in detection of urinary calculi. Methods 238 cases of urinary calculi were researched,including the mineral composition and the size（height and width} of calculi, the occurrence of acoustic shadowing and comet tail artifacts, then analyzed those relevant relationships by Statistical Analysis System. Results （ 1） There was no statistical relationship between the acoustic shadowing artifacts and urinary calculi mineral composition（ P〈0.05 ） ; （ 2 ） There was a statistically relevant relationship between the occurrence of acoustic shadowing artifacts and urinary calculi height（thickness）（P〈0.05）, but no statistical relationship with urinary calculi width（ P〉0.05） ;（3）There was no statistical relationship between the occurrence of comet tail artifacts and urinary calculi width or height（P〉0. 05）. Conclusion （1 ）The occurrence of acoustic shadowing and comet tail artifacts is no relationship with urinary calculi mineral composition, and can not be used to predict urinary calculi mineral composition;（2）There is a directly relationship between the occurrence of acoustic shadowing artifacts and urinary calculi height, but there is no relationship between the occurrence of comet tail artifacts and urinary calculi width or height.
