Purpose: Of the various methods of hemodynamic studies performed to evaluate erectile dysfunction penile color Doppler ultrasound is currently considered the best. However, intracavernous injection is invasive and has adverse effects, such as prolonged erection. We evaluated whether sildenafil may be used as a substitute for intracavernous agents when assessing impotence on color Doppler ultrasound.
