Abstract
- To assess the penile hemodynamic function and penile anatomy, duplex ultrasonography combined with intracavernous papaverine injection was undertaken in psychogenic, neurogenic and vasculogenic impotence patients, and patients with priapism and Peyronie's disease Patients. The results were as follows ; 1. In 7 neurogenic and 7 psychogenic impotence patients, changes of luminal diameter of cavernous artery and peak flow velocity were 0.69 +/- 0.13mm, 8.99 +/- 2.54cm/sec in flaccid phase, and 1.13 +/- 0.12mm, 21.38 +/- 8.43cm/sec in erection phase. 2. In 4 vasculogenic impotence patients, changes of luminal diameter and peak flow velocity were minimal. 3. Penile ultrasound is considered valuable in the evaluation of extent of Peyronie's plaque and determination of the type of priapism. Penile duplex ultrasonography combined with papaverine injection is considered the best screening method of vasculogenic impotence, and valuable in the evaluation of the penile structures.
