RESUMEN
<p><b>OBJECTIVE</b>To evaluate the diagnosis and treatment of high-flow priapism (HFP).</p><p><b>METHODS</b>Four cases of HFP following blunt trauma to the penis or perinea underwent diagnostic examination by colour-flow Doppler ultrasound and/or superselective pudendal arteriography, which revealed bilateral arteriocorporal fistula in 1 case and monolateral in the other 3. Penile detumescence was obtained in 2 cases by superselective bilateral/monolateral arteriographic embolization of the pudendal artery with absorbable gelatin</p><p><b>RESULTS</b>The former 2 cases effected an immediate recovery of the sponge, while the other 2 cases received conservative treatment. Erectile function, able to perform normal sexual intercourse in approximately 2 months. But in the latter 2, follow-up revealed unsatisfactory potency.</p><p><b>CONCLUSION</b>Superselective arteriographic embolization with absorbable gelatin sponge can provide a safe, selective and effective treatment for HFP patients.</p>
