目的探讨彩色多普勒对睾丸扭转的诊断价值。方法首先用二维超声显示１６例疑为睾丸扭转的睾丸附睾形态结构及内部回声，再用彩色多普勒观察血供状况，并全部经手术病理证实。结果１５例病侧睾丸血流消失或减少，睾丸内血流阻力指数增高，超声诊断睾丸扭转，与手术病理诊断相符；１例彩超未见血流减少，超声误诊为附睾炎。结论彩超诊断睾丸扭转正确率高（９３．８％），具有较高的敏感性和特异性，无创伤，简便易行，且能较准确地判断睾丸扭转的程度及病情发展的不同时期，为手术的选择提供了有效的依据，也可作为手术复位疗效评价的依据，应作为诊断睾丸扭转的首选方法
Objective To investigate the diagnostic value of color Doppler ultrasound in the diagnosis of testicular torsion. Methods The morphology and internal echo of 16 cases of testicular epididymis suspected of testicular torsion were observed by two-dimensional ultrasonography. The blood supply was observed by color Doppler and confirmed by pathology. Results 15 cases of testicular blood loss or decrease on the side of the testes increased resistance index, testicular ultrasound diagnosis of torsion, consistent with the surgical diagnosis; one case of ultrasonographic no blood flow, ultrasound misdiagnosed as epididymitis. Conclusion The diagnosis of testicular torsion by color Doppler ultrasound is accurate (93.8%), with high sensitivity and specificity, non-invasive, simple and easy to determine, and can more accurately determine the extent of testicular torsion and disease development at different stages of The choice of surgery provides a valid basis, but also can be used as the basis for the evaluation of the efficacy of surgical reduction, should be used as the preferred method of diagnosis of testicular torsion
