[Application of colour Doppler ultrasonography in the diagnosis of vasculogenic erectile dysfunction].
OBJECTIVE
To evaluate the clinic value of doppler ultrasonography in diagnosis of vasculogenic erectile dysfunction (ED).


METHODS
The hemodynamic change was obsreved by doppler ultrasonography during the erection of penis and the results between patients with vasculogenic ED and controls were compared. The doppler ultrasonographic characteristics of vascular ED was analyzed.


RESULTS
In the patients with arterial ED the peak systolic velocity(PSV) in deep artery was apparently lower than controls(P < 0.01), and in the patients with venous ED, the velocity of deep dorsal vein was higher during complete erection than controls(P < 0.05).


CONCLUSIONS
The result of doppler ultrasonography examination effectively helps the diagnosis of vasculogenic.
