[High flow priapism].

Four cases with high flow priapism are described herein. Patient evaluation included intracavernal blood-gasmetry, echo Doppler, selective arteriography of the pudendal artery. Three patients had a previous history of trauma and one patient was on psychotropics. The alpha-agonist drugs and the different shunt techniques did not achieve detumescence. Two embolization procedures of the internal pudendal artery were performed with good long-term results. The other two cases achieved spontaneous detumescence. No complications or secondary erectile dysfunction were observed.
