To define the ultrasound (US) prevalence of varicoceles after surgical repair, 28 postoperative patients underwent color Doppler US. A group of 26 control subjects also underwent color Doppler US to establish the prevalence of varicoceles in the healthy population. Eighteen of 28 (64%) patients who underwent color Doppler US scanning 16.4 months, on average, after varicocele repair had evidence of a varicocele, a number similar to that reported in other series for infertile men before surgery. Dominant veins in the postoperative patients were larger (P < .01) than those in the control subjects. Postoperative improvements in sperm parameters and conception rate in our subjects were 58% and 43%, respectively, consistent with findings reported in the literature. The prevalence of varicoceles detected at color Doppler US in our healthy population was 42% (11 of 26). Physical examination after surgery failed to show a varicocele in 20 of 22 (91%) patients examined. The discrepancy between sperm parameters and the results of color Doppler US and physical examination raises questions about the utility of US as a means of evaluation in the postvaricocelectomy patient.
为了确定手术修复后精索静脉曲张的超声（US）患病率，对28例术后患者进行了彩色多普勒超声检查。另外选取26名对照受试者也进行了彩色多普勒超声检查，以确定健康人群中精索静脉曲张的患病率。在精索静脉曲张修复术后平均16.4个月接受彩色多普勒超声扫描的28例患者中，有18例（64%）有精索静脉曲张的迹象，这一数字与其他系列报道的术前不育男性的数字相似。术后患者的主要静脉比对照受试者的要粗大（P <.01）。我们研究对象的精子参数和受孕率术后改善率分别为58%和43%，与文献报道的结果一致。在我们的健康人群中，彩色多普勒超声检测到的精索静脉曲张患病率为42%（26例中有11例）。在接受检查的22例患者中，有20例（91%）术后体格检查未发现精索静脉曲张。精子参数与彩色多普勒超声及体格检查结果之间的差异，引发了关于超声作为精索静脉曲张切除术后患者评估手段实用性的质疑。
