彩色多普勒超声诊断儿童睾丸附件扭转的临床价值

Clinical value of color Doppler ultrasound in diagnosis of pediatric testicular appendage torsion

目的探讨彩色多普勒超声在睾丸附件扭转中的临床诊断价值。方法回顾性分析137例因急性阴囊疼痛进行手术治疗患儿的彩色多普勒超声检查资料,并与手术结果进行比较,计算超声诊断睾丸附件扭转的特异性、敏感性、阳性预测值、阴性预测值、准确率及漏诊率。结果 137例患儿,手术确诊睾丸附件扭转124例;超声诊断睾丸附件扭转111例,主要声像图表现为睾丸周围与附睾间低、等、高回声结节;CDFI示肿大的附件多无血流信号,同时伴有睾丸、附睾血流信号增多,少量鞘膜积液和阴囊壁增厚。超声诊断睾丸附件扭转的特异性、敏感性、阳性预测值、阴性预测值及诊断符合率分别为100%、89.5%、100%、50.0%及90.5%。结论彩色多普勒超声诊断睾丸附件扭转有一定的临床价值,可作为诊断睾丸附件扭转首选的影像学方法。

Objective To explore the clinical value of color Doppler ultrasound in the diagnosis of testicular appendage torsion.Methods One hundred and thirty-seven children with acute scrotum were underwent surgery were enrolled in this study,their color Dopper ultrasonic data were analyzed retrospectively,the results was compared with that of the surgery,the specificity,sensitivity,positive predictive value,negative predictive value,accuracy and misdiagnose rate of ultrasound in diagnosis of were calculated.Results In 137 cases,124 cases of testicular appendage torsion were diagnosed by surgery,111 cases of testicular appendage torsion were diagnosed by color Doppler ultrasound.Ultrasound images showed that testicle and epididymis hypoechoic,iso-echoic or hyoerechoic nodule between the testicle and epididymis.Color Doppler flow imaging showed that there were no significant blood flow in the enlarged attachments,increaseed blood flow in testis and epididymis was found,with testicular sheath effusion and thicken scrotal wall.The specificity,sensitivity,positive predictive value,negative predictive value,accuracy rate,misdiagnose rateof ultrasound in diagnosis of testicular appendage torsion were 100%,89.5%,100%,50.0%,90.5%,respectively.Conclusion Color Dopper ultrasound has a certain clinical value in diagnosis of testicular appendage torsion,and can be used as the preferred imaging method in diagnosis of testicular appendage torsion.
