Twenty-eight clinically detectable varicoceles of various sizes were examined with a Doppler ultrasonic stethoscope. Retrograde blood flow through the left internal spermatic vein was confirmed in all cases irrespective of size of the vascular abnormality. The Doppler stethoscope also was used to evaluate 13 patients suspected of having varicoceles but with inconclusive physical examinations. Retrograde flow through the internal spermatic vein could likewise be auscultated in 5 of these patients. Finally, the Doppler stethoscope was used to determine the adequacy of internal spermatic vein ligation in 5 postoperative patients whose seminal dysfunction persisted despite what appeared to be a surgically effective correction of aberrant gonadal venous flow.
使用多普勒超声听诊器对28例临床可检测到的不同大小的精索静脉曲张进行了检查。所有病例均证实有血液经左精索内静脉逆流，不论血管异常的大小如何。多普勒听诊器还用于评估13例疑似精索静脉曲张但体格检查结果不明确的患者。在其中5例患者中同样可听诊到血液经精索内静脉逆流。最后，多普勒听诊器用于确定5例术后患者精索内静脉结扎是否充分，这些患者尽管性腺静脉血流异常在手术中似乎已得到有效纠正，但仍存在精液功能障碍。
