目的:评估彩色多普勒超声在小儿急性睾丸扭转诊断中的应用效果?方法:在2018年1月至2020年12月期间，从前来我院就诊的阴囊肿胀且长时间疼痛的患儿中进行筛选，选择80例患儿作为本次研究的对象?所有患儿均接受了彩色多普勒超声检查，观察患儿超声图像特点，并将超声检查结果与术中及检查结果进行比较?计算彩色多普勒超声诊断的准确率?结果:彩色多普勒超声诊断小儿急性睾丸扭转的准确率为93.33%(28/30)，超声检查可见睾丸附件扭转部位非匀质性低回声，图像呈圆形或类圆形，患侧内未见明显彩色血流信号，周边可见少许彩“,”Objective:To evaluate the application of color Doppler ultrasonography in the diagnosis of acute testicular torsion in children.Methods:From January 2018 to December 2020,80 children with swelling of the scrotum and prolonged pain were selected as the subjects of this study.All the children received color Doppler ultrasound examination,and the characteristics of ultrasound images were observed,and the results of ultrasound examination were compared with intraoperative and examination and scrotal radionuclide scan.The diagnostic accuracy of color Doppler ultrasonography was calculated.Results:The accuracy of color Doppler ultrasonography in the diagnosis of acute testicular torsion in chil-dren was 93.33%(28 / 30）.The ultrasonography showed non-uniform hypoecho in the torsion of testicular appendage,and the image was round or quasi-round.There was no obvious color blood flow signal in the affected side,and a few color blood flow signals were seen around the affected side.Color Doppler ultrasound examination of testicular torsion internal blood flow signal decreased or disappeared,the spectrum morphology changed.Conclusion:Color Doppler ultrasonography has a high accuracy in the diagnosis of acute testicular torsion in children,and can effectively identify testicular torsion,which provides a favorable basis for clinical diagnosis and treatment.
