高频彩色多普勒超声对急性附睾炎诊断的临床价值

目的探讨高频彩超对于急性附睾炎诊断的实用性。方法回顾性分析既往49例急性附睾炎病人进行的高频彩色多普勒超声检查的影像资料；同时选择49例健康者作为对照组。结果急性附睾炎表现为附睾不同程度肿大，多位于附睾尾部，附睾头部及体部较少见。病灶处超声表现多为偏低回声，表现为弥漫性和（或）结节状，部分患者同时合并有睾丸炎、鞘膜积液、精索静脉曲张等。急性附睾炎彩色多普勒显示肿大的附睾内血流信号丰富，最大血流速度、阻力指数均和正常附睾有显著差异。结论高频彩超是检查急性附睾炎的首选方法，诊断符合率高、特异性较强，具有极高的临床应用价值。

Clinical Value of High Frequency Color Doppler Ultrasound in the Diagnosis of Acute Epididymitis

Objective To explore the clinical value of high frequency color doppler ultrasound in the diagnosis of acute epididymitis. Methods The clinical data of 49 patients with acute epididymitis through high frequency color doppler ultrasound check were analyzed retrospectively. Another 49 healthy cases were chosen as control group. Results The clinical manifestations by ultrasonography was a different extent epididymis swelling most common in a epididymis tail, but rarely found in epididymis head and body part. Uhrasonographic findings were shown as low level echoes with diffused / nodular, some patients suffered from orchitis, hydrocele and varicocele. The uhrasonography showed that enlargement had abundant blood flow signals, and there was difference in the maximum of blood flow velocity and resistance index （ RI ） between swollen and normal epididymitis. Conclusion High frequency color doppler ultrasound is valuable diagnosis method on acute epididymitis with high diagnostic accuracy and specificity. It is a preferred method in clinical use.
