[Venous insufficiency of the corpora cavernosa as (additional) cause of erectile dysfunction]

In 25-30% of the patients with erectile dysfunction, venous insufficiency is the (additional) reason for the erectile failure. Surgical procedures and prognosis depend largely on the precise localisation of the pathological drainage. The venous leakage is proven and exactly localized by a multiprojectional cavernosography, measurement of the maintainance flow and intracavernous pressure monitoring. The most reliable screening test for venous erectile dysfunction is the intracavernous application of a standardised vasoactive drug combination.
