[Stasis priapism secondary to PGE1: transformation into high-flow priapism].

Since vasoactive agents were first introduced for the diagnosis and treatment of Erectile Dysfunction (ED), the most feared side effect has been priapism. The arrival of Prostaglandin E1 (PGE1) limited to a large extent the incidence of this complication due to its fast systemic and intracavernous metabolism. A case of stasis priapism following a low dose PGE1 injection (10 mcg) after 48 hours evolution and its surprising conversion to high flow priapism after the surgical procedures performed to solve this complication is presented here.
