Table 3.
Pulsed-wave Doppler parameters derived from three different regions drawn within pampiniform plexus, marginal, and intra-testicular arteries of pathological testicles with different tumor lesions (n = 33) included in the comparative analysis. Peak systolic velocity = PSV, End diastolic velocity = EDV, Resistance index = RI, Pulsatility index = PI. Values are means ± S.D.
