[Selective embolization for arterial priapism: A report of 5 cases].

OBJECTIVE

To introduce our experience in the treatment of arterial priapism by superselective embolization.

METHODS

This study included 5 cases of perineal trauma-induced arterial erectile dysfunction treated in our departmentbetween February 2011 and May 2015, all failingpreviously to respond to 3 weeks of conservative treatment. The patients were aged 25－47 (mean 35) years, with the onset of arterial priapism at 2－5 days after trauma, and all subjected to physical examination, blood gas analysis, color Doppler ultrasonography of the corpora cavernosum, and IIEF-5 scoring. All the patients underwent superselective embolization, followed by local pressing and cold compression, and IIEF-5 scores were obtained again at 6 and 12 months postoperatively.

RESULTS

All the patients had normal erectile functionbefore trauma, with a mean IIEF-5 scoreof 24.60 ± 0.55. Complete detumescenceor painless flaccidity of the penis was achieved in 1 case immediately after surgery and in the other 4 after 3－17 days of postoperative conservative treatment. None of the patients needed a second embolization and no relapse was found during a mean follow-upof 27.2 (13－48)months. The IIEF-5 scores obtained at 6 (24.00 ± 1.02) and 12 months (24.20 ± 0.82) were normal, with no statistically significant differencesfrom that before trauma.

CONCLUSIONS

Selective embolization is a safe and effective option for the treatment of arterial priapism. In case of no immediate painless flaccidity of the penis after surgery, conservative treatment can be extended rather than a second operation.
