Abstract
Varicocele has been identified as an important cause of male infertility where its influence on men’s reproductive capacity is due to its markedly diverse effects on the testicles. This study aimed to assess the value of ultrasonographic parameters of the spermatic veins at the inguinal and scrotal levels in varicocele diagnosis and post-operative evaluation. Forty-five infertile men associated with varicocele and 15 fertile men were subjected to history taking, genital examination and semen analysis. In addition, inguinal and scrotal ultrasonography was carried out pre-varicocelectomy and 3 months post-varicocelectomy. At both the scrotal or inguinal levels, the mean spermatic vein diameter demonstrated significant post-operative decrease compared with the pre-operative resting condition and on Valsalva’ manoeuvre. The mean diameters of the pampiniform plexus of veins also demonstrated significant decreases post-operatively compared with the pre-operative resting condition or on Valsalva’ manoeuvre. It is concluded that colour Doppler ultrasound is a reliable and noninvasive method that is useful not only for diagnosis but also for post-varicocele repair follow-up.
