Bilateral Cavernosal Artery Ligation to Treat Ischemic Priapism Following Inflatable Penile Prosthesis Implantation.

OBJECTIVE

To describe the first known case of recurrent acute priapism after penile prosthesis implantation.

MATERIALS AND METHODS

A 60-year-old gentleman with a history of recurrent ischemic priapism without hemoglobinopathy presented with refractory erectile dysfunction and underwent uncomplicated penile prosthesis placement. His course was complicated by early acute ischemic priapism confirmed via ultrasound. Due to his pain, attempts to relieve the priapism using ultrasound-guided phenylephrine injections were attempted but were unsuccessful.

RESULTS

He subsequently underwent exploration with confirmation of distal ischemic priapism followed by brisk bright red blood from the proximal corpora upon device externalization. A perineal exploration was performed and the bilateral cavernosal arteries were suture ligated with immediate relief. The device was reimplanted and the patient recovered uneventfully.

CONCLUSION

We report the first known case of ischemic priapism following inflatable penile prosthesis implantation. The details of this case challenge the dogma that priapism is a binary event and instead supports an imbalance between unopposed cavernosal artery inflow possibly due to vascular calcifications and compromised venous outflow due to the presence of the device. Prosthetic urologists should be aware of this rare phenomenon and consider all available approaches on an individualized case-by-case basis.
