Vascular investigation of erectile disturbances.

Introduction: Since its development echoDoppler investigation has become th e mainstay in the diagnosis of vascular impotence. This paper reviews its p resent use. Method: Personal experience and a review of the literature form the basis o f a critical analysis of this investigation. Results: The standardised technique proposed by the AA for the echoDoppler investigation of impotence includes: Doppler examination of the dorsal and deep arteries of the penis; a pharmacological test with volume measurements and direct examination of the penile arteries by pulsed echoDoppler. Futur e developments will allow venous exploration (of the deep Vein of the penis ); power Doppler examination of the 2nd and 3rd degree arteries of the peni s. Conclusions: There is no present consensus. The arterial inflow, cavernoven ous retention and overall size of the erection, can be quantified.
