Recently, penile duplex ultrasonography with intracavernosal injection has been used in assessing arterial compliance, flow velocity, and anatomic structure in patients with suspected vasculogenic impotence. Herein, we report our experience with
color-flow penile duplex ultrasonography in 37 impotent men using intracavernosal prostaglandin E1 injection. Among them, 22 hosed normal vascular findings, 7 arterial insufficiency, and 8 venous leakage.
The mean peak systolic velocity in the cavernosal artery was 43±18.9 cm/sec in patients with normal vascular findings, 42±16.2 cm/sec in the venous leakage cases, and 20±7.3 cm/sec in the arterial insufficiency cases.
The mean end-diastolic velocity in the venous leakage cases was greater than that of the other two groups. Color-flow penile duplex ultrasonography with intracavernosal prostaglandin E1 injection may be useful in screening for vasculogenic
impotence.
