摘　　要：目的对比彩色多普勒闪烁伪像与灰阶超声对泌尿系结石的诊断效能。方法选取2020年10月至2022年10月我院收治的72例疑似泌尿系结石患者,均进行彩超、多层螺旋CT检查。统计彩色多普勒闪烁伪像与灰阶超声的诊断结果,以多层螺旋CT检查结果作为“金标准”,比较两种超声检查方法对泌尿系结石的诊断效能。结果多层螺旋CT检查显示,72例疑似泌尿系结石患者中有47例确诊为泌尿系结石。彩色多普勒闪烁伪像诊断泌尿系结石的准确性、灵敏度、特异度、阳性预测值、阴性预测值均高于灰阶超声(P<0.05)。结论与灰阶超声相比,彩色多普勒闪烁伪像诊断泌尿系结石的效能更高,值得临床推广应用。Objective To compare the efficacy of color Doppler twinkling artifact and gray-scale ultrasound in the diagnosis of urinary calculi.Methods A total of 72 patients with suspected urinary calculi admitted to our hospital from October 2020 to October 2022 were selected.All cases were examined by color Doppler ultrasound and multi-slice spiral CT.The diagnostic results of color Doppler twinkling artifact and gray-scale ultrasound were counted.With the result of multi-slice spiral CT examination as"gold standard",the diagnostic efficacy of the two ultrasound examination methods for urinary calculi was analyzed.Results Multi-slice spiral CT examination showed that 47 of the 72 patients with suspected urinary calculi were diagnosed with urinary calculi.The accuracy,sensitivity,specificity,positive predictive value and negative predictive value of color Doppler twinkling artifact in the diagnosis of urinary calculi were higher than those of gray-scale ultrasound(P<0.05).Conclusions Compared with gray-scale ultrasound,color Doppler twinkling artifact is more effective in the diagnosis of urinary calculi,which is worthy of clinical promotion and application.
