Summary

Vascular lesions causing impotence can be diagnosed using cavernography-cavernometry. This method identifies venous leakage by measuring penile blood flow after papaverine injection, aiding in diagnosing erectile dysfunction.

Background:

Vascular lesions are a primary cause of organic impotence.
Dysfunction of the penile veno-occlusive mechanism contributes to erectile dysfunction.

Purpose of the Study:

To investigate the role of cavernography-cavernometry in diagnosing veno-occlusive dysfunction.
To establish criteria for identifying venous leakage as a cause of impotence.

Main Methods:

Cavernography-cavernometry was employed to study penile veno-occlusive function.
Intracavernous papaverine injection (60 mg) was administered.
Maintenance flow was measured after papaverine administration.

Main Results:

A maintenance flow less than 25 ml/min post-papaverine injection is a key indicator of venous leakage.
Cavernography effectively visualizes abnormal venous drainage in the erect state.

Conclusions:

Cavernography-cavernometry is a valuable diagnostic tool for identifying vascular causes of erectile dysfunction.
Abnormal venous drainage, indicated by low maintenance flow, is a significant factor in organic impotence.
