Purpose: To determine effectiveness of Valsalva maneuver and standing position on scrotal color Doppler ultrasound (CDU) for thevaricocele diagnosis. Materials and Methods: We reviewed the physical examination and CDU finding in 87 patients who visited National Police Hospitalfrom January 2011 to April 2014. Diameters of pampiniform plexus were measured bilaterally during resting and Valsalvamaneuver in the supine position and standing position. We calculated the ratio of mean of maximal vein diameter (mMVD) duringresting and Valsalva maneuver (resting-Valsalva ratio) and compared in the both position. Results: In the resting and supine position, mMVD of varicocele testis units were 1.8 mm, 2.1 mm, 2.6 mm (grades I, II, III, respectively),and that of normal testis units (NTU) 1.2 mm. During Valsalva maneuver in the supine position, mMVD were 3.0 mm, 3.4mm, 4.2 mm (grades I, II, III) vs 1.8 mm (NTU) (p=0.007, p<0.001, p<0.001, respectively). Average of resting-Valsalva ratio in thesupine position were 0.69, 0.74, 0.74 (grades I, II, III) and 0.67 (NTU). Whereas in the resting and standing position, mMVD were 2.8mm, 3.3 mm, 3.8 mm (grades I, II, III) and 1.8 mm (NTU) (p=0.002, p<0.001, p<0.001). During Valsalva maneuver in the standingposition, mMVD were 5.0 mm, 5.8 mm, 6.6 mm (grades I, II, III) and 2.5 mm (NTU) (p=0.002, p<0.001, p<0.001). And average resting-Valsalva ratio were 0.76, 0.90, 0.71 (grades I, II, III) and 0.26 (NTU), which showed significant differences from all grades (p<0.001,p<0.001, p<0.001). Conclusions: It is suggested that the standing position and Valsalva maneuver during CDU could improve diagnostic ability forvaricocele. Resting-Valsalva ratio in the standing position could be a new diagnostic index for varicocele diagnosis using CDU.
