Determination of Erectile Penile Volume by Ultrasonography

Abstract
A total of 58 men with organic erectile dysfunction underwent penile blood flow studies with a 10 MHz. high resolution ultrasonogram and pulsed Doppler analysis after papaverine injection. The average volume increase for the entire group was 52.62 cc (445.9 per cent). No statistical differences in volume increase were noted among 3 groups separated by age. The average volume increase in 23 patients with venous insufficiency was greater than that in 20 patients with primary arterial insufficiency (p <0.033). Eleven patients who had erections satisfactory for vaginal penetration after papaverine injection had a statistically greater increase in penile length but no difference in volume increase than those with a poor response.
