Purpose: To evaluate the effectiveness and safety of treatment of high-flow priapism (HFP) with superselective transcatheter embolization at nine university hospitals. Materials and Methods: Between May 1994 and October 2006, 27 patients underwent superselective embolization of the cavernous artery for HFP. Trauma was apparent in 22 patients, there was self-administered intracavernosal injection for erectile dysfunction in two, and the remaining three did not recall any penile or perineal trauma. The embolic agents used were autologous blood clot (n = 12), gelatin sponge (n = 12), microcoils combined with gelatin sponge (n = 1), polyvinyl alcohol (n = 1), and N-butyl cyanoacrylate (n = 1). Recurrence of priapism and change in erectile function were evaluated during a mean follow-up of 13 months. Differences in results between patients treated with autologous blood clot versus gelatin sponge were statistically analyzed with use of the χ2 test. Results: In 24 of 27 patients (89%), a single embolization was sufficient for complete resolution of priapism. Repeat embolization was required in two patients (7%), and in the remaining patient (4%), shunt surgery was performed after embolization as a result of HFP coexisting with corporeal venoocclusive dysfunction. Eighteen of 23 patients (78%) who had premorbid normal erectile function showed maintained potency during the follow-up period. There was no significant difference affecting required repeat embolization (P = .537) and change in quality of erection (P = .615) during the follow-up period between the autologous blood clot and gelatin sponge treatment groups. Conclusions: Superselective transcatheter embolization in the treatment of HFP is effective and ensures a high level of preservation of premorbid erectile function.
