High resolution color Doppler ultrasound is a noninvasive means of simultaneously imaging and evaluating the blood flow to the testes. To define the ability of color Doppler ultrasound to detect clinically evident as well as subclinical varicoceles men referred to our urology division with oligospermia and infertility underwent spermatic vein venography of the left testis if there was physical examination and/or color Doppler ultrasound evidence of a varicocele. The detection of valvular incompetence on venography was considered diagnostic for a varicocele. Of 17 study patients physical examination detected 10 of 14 venographically evident varicoceles (71%), whereas color Doppler ultrasound detected 13 of 14 (93%). Of 5 patients with a normal physical examination but with color Doppler ultrasound evidence of a varicocele 4 had a confirmatory venogram, and 1 of 2 patients with a varicocele on physical examination and a normal Doppler ultrasound had a positive venogram. These data suggest that color Doppler ultrasound of the testis may more appropriately direct further invasive testing and therapy of infertile men than physical examination alone.
高分辨率彩色多普勒超声是一种用于同时成像和评估睾丸血流的非侵入性方法。为了确定彩色多普勒超声检测临床明显以及亚临床精索静脉曲张的能力，因少精子症和不育症转诊至我们泌尿外科的男性患者，如果体格检查和/或彩色多普勒超声有精索静脉曲张的证据，则对左侧睾丸进行精索静脉造影。静脉造影中瓣膜功能不全的检测被认为是精索静脉曲张的诊断依据。在17例研究患者中，体格检查发现14例静脉造影明显的精索静脉曲张中有10例（71%），而彩色多普勒超声发现14例中的13例（93%）。在5例体格检查正常但彩色多普勒超声有精索静脉曲张证据的患者中，4例进行了确诊静脉造影，在2例体格检查有精索静脉曲张但多普勒超声正常的患者中，1例静脉造影呈阳性。这些数据表明，睾丸彩色多普勒超声可能比单独的体格检查更适合指导对不育男性进行进一步的侵入性检查和治疗。
