[A critical study of the penile Doppler test. Considerations apropos of a personal series of over 850 patients tested for the evaluation of impotence since 1983].

The penial Doppler is, in 1990, the first intention examination the most asked for when there is a suspicion of a vascular origin in an erection problem. In fact, due to the technical difficulties to carry it out, this examination presents many uncertainties in its interpretation, and can even be the source of diagnostic errors. The aim of this study is to argue in favour of a systematic intracavernous injection of 8 mg of papaverine when the penial Doppler is carried out, enabling an increase in its diagnostic value and often a therapeutic orientation straightaway.
