摘要
探讨闪烁征(twinklingartifact,TA)对肾脏结石的超声诊断价值。超声诊断为肾结石并经CT证实为肾结石的临床资料61例,共纳入69枚结石(直径3-9mm,平均5.6mm),根据结石直径分为两组:小结石组(直径≤5mm)33枚、中结石组(5 mm<直径≤10mm)36枚,观察声影及闪烁征显示的情况。小结石组中闪烁征的显示率高于声影的显示率,差别有统计学意义(P<0.05),而在中结石组中差别无统计学意义(P>0.05)。在小结石组的声影显示率低于中结石组中的显示率,差别有统计学意义,而闪烁征在两组间的显示率差异并无统计学差异。结石大小对闪烁征的显示无明显影响。利用闪烁征作为肾结石的诊断指标,可提高直径<5mm的小结石的检出率。
To explore the diagnostic value of twinkling artifact in renal calculus.61 patients with renal calculus who were diagnosed by ultrasonography and confirmed by computed tomography（ CT） were enrolled in this study.Altogether69 pieces of renal calculus（ diameter： 3-9mm,mean： 5. 6mm） were divided into two groups. Group A： the diameter of the stone is smaller than 5mm,group B： the diameter of the stone is 5-10 mm.The frequency of the occurrence of the acoustic shadow and twinkling artifact for each calculi in two groups was observed and recorded,respectively.The occurrence rate of TA was significantly higher than that of the acoustic shadow for kidney calculus diagnosis in group A（ P〈0. 05）,but no significant difference was found in group B（ P〉0. 05）.The occurrence rate of acoustic shadowing for kidney calculus diagnosis in group A is significantly lower than that of it in group B（ P 〉0. 05）. No obvious difference of the occurrence of TA between two groups（ P〈0. 05）.The occurrence of TA is not influenced by the size of renal calculus.TA is useful in the diagnosis of renal calculus,especially for small stones（ 5mm）.
