Anatomo-functional considerations on venogenic impotence.

The authors report their clinical experience with cavernosography and cavernosometry on impotent patients. The indications of method and its correct place in the diagnostic workup are underscored. The methods of evaluation are described, highlighting the advantages of a diagnostic pharmacological approach in respect to a near as possible physiological haemodynamic evaluation. Finally they propose a future development for the method, such as the use of PGE1 instead of the commonly employed drugs, and a new classification for the veno-occlusive disease with stage and grade.
