Color Doppler ultrasound imaging in varicoceles: is the venous diameter sufficient for predicting clinical and subclinical varicocele?
Investigating the diagnostic value of color Doppler ultrasound for defining the varicocele grade according to WHO criteria. ⋯ Our findings support the hypothesis that clinical varicoceles can be predicted with high accuracy based only on the diameter of testicular veins using cut-point values of >2.45 mm in rest or >2.95 mm during Valsalva maneuver in the supine position.
