Erection due to a venous cause - Venous priapism

High urgency
-Moderately severe

Venoocclusive Priapism is prolonged and painful erection, not linked to sexual stimulation, due to an insufficient venous drainage.

The total or partial occlusion of the veins that prevents blood from leaving the erect penis may have external or internal causes.

Its main clinical manifestation is a painful erection lasting for hours.

Diagnosis is based on the collection of a full medical history and physical examination of the member. Additional tests may include echo-Doppler and/or blood gas tests.

Treatment requires treating the triggering cause, if known. If the erection continues after 3 or 4 hours, appropriate treatment should be started.
