为研究精索扭转的彩色多普勒超声（ＣＤＵ）表现及其诊断价值，采用彩色多普勒电脑声像仪对１３例精索扭转、１７例急性睾丸附睾炎及７２例正常睾丸进行检查。异常３０例中，１０例进行手术治疗，其余病例经随访得到诊断结果。ＣＤＵ诊断精索扭转敏感性为９２．３％，特异性为１００％。研究表明，ＣＤＵ能够发现精索扭转并评价其程度，可帮助临床医师迅速准确地作出诊断 To study the color Doppler ultrasound (CDU) performance and its diagnostic value of stenosed twisting, 13 cases of spermatic cord torsion, 17 cases of acute testicular epididymitis and 72 cases of normal testis were examined by color Doppler computer imager. In 30 cases, 10 cases were treated surgically, and the remaining cases were followed up for diagnosis. CDU diagnosis of spermatic cord torsion sensitivity was 92.3%, specificity of 100%. Studies have shown that the CDU can detect slippage and assess the extent of sphincter, which can help clinicians make a quick and accurate diagnosis
