Abstract
Purpose: We assessed whether re-dosing of a vasoactive agent or the combination of a vasoactive injection and genital plus audiovisual sexual stimulation caused the greatest erectile effect to determine which of the 2 procedures would be better for dynamic penile color Doppler sonography in patients with erectile dysfunction. Materials and Methods: A total of 20 consecutive patients with erectile dysfunction underwent 2 sessions under real-time RigiScan* recording of penile erection. Session 1 consisted of adaptation in 10 minutes, intracavernous injection of 10 μg. alprostadil in 10 minutes and re-dosing of 10 μg. alprostadil in 10 minutes. Session 2 consisted of adaptation in 10 minutes, injection of 10 μg. alprostadil in 10 minutes and genital plus audiovisual sexual stimulation in 10 minutes. The total duration of each session was 30 minutes. The order of the 2 sessions was randomly assigned with a week interval between each session. Results: Re- dosing and genital plus audiovisual sexual stimulation caused a significant increase in erectile response compared to the result seen after the first injection (re-dosing p
