[Diagnosis of venous insufficiency in erectile dysfunction: comparative studies of cavernosonography and Doppler sonography].

In 26 out of 214 patients with erectile dysfunction and venous insufficiency proven by cavernosography, bidirectional Doppler ultrasound was also performed to demonstrate venous leakage in addition. Except for one, all 25 cases of leakage in the superficial and deep dorsal veins could be demonstrated, as could four of six cases of cavernosoglandular shunts. Using bidirectional Doppler ultrasound, it was possible to visualize a continuous orthograde blood flow from the sulcus coronarius to the root of the penis in superficial and deep dorsal penile veins, as well as in ectopic penile veins, and a retrograde blood flow in the sulcus coronarius in cavernosoglandular shunts.
