In 63% of 265 patients with erectile dysfunction a relevant
arterial inflow disturbance was found by Doppler ultrasound
examination. Correlation between Doppler and arteriography in 58
patients showed an accuracy of 95% in detecting penile arteries and
an accuracy of 91% in discovering a pathological arterial pattern
(arterial anomaly or arteriosclerotic obstruction). In 15 patients
the arterial inflow was measured additionally by Doppler ultrasound
technique after intracavernosal injection of vasoactive drugs
(IIVD) (7.5 mg papaverine and 0.25 mg phentolamine). This technique
proved to be more reliable than in the flaccid state and markedly
facilitated localization and assessment of pathological changes of
the cavernosal arteries.
