Color flow Doppler sonography (CFDS) has been used to evaluate the blood flow to the testes, because of its ability to visualize small vessels with low flow. A total of 39 infertile men, 18 with clinical varicocele and 21 without, were examined using CFDS to assess the clinical usefulness of this technique. In patients with varicocele, venous diameter in the pampiniform plexus was greater than 2 mm, whereas those without varicocele showed diameters of less than 1.8 mm. Of 21 patients without varicocele on physical examination, 13 were found to have reflux by CFDS. According to clinical and CFDS findings, patients were divided into five groups: varicocele negative, suspicious subclinical varicocele, subclinical varicocele, manifest varicocele with Valsalva-induced reflux, and manifest varicocele. These data suggest that the CFDS technique is a simple, sensitive and noninvasive modality for the accurate diagnosis of varicocele.
彩色多普勒超声检查（CFDS）已被用于评估睾丸的血流情况，因为它能够显示低流量的小血管。共有39名不育男性接受了CFDS检查，其中18名患有临床精索静脉曲张，21名没有。通过CFDS评估该技术的临床实用性。精索静脉曲张患者的蔓状静脉丛静脉直径大于2mm，而无精索静脉曲张者的直径小于1.8mm。在体格检查无精索静脉曲张的21名患者中，13名通过CFDS发现有反流。根据临床和CFDS检查结果，患者被分为五组：精索静脉曲张阴性、可疑亚临床精索静脉曲张、亚临床精索静脉曲张、伴有瓦尔萨尔瓦动作诱发反流的显性精索静脉曲张和显性精索静脉曲张。这些数据表明，CFDS技术是一种简单、敏感且无创的方法，可用于准确诊断精索静脉曲张。
