Comprehensive Imaging Review of Penile Prosthesis

Erectile dysfunction is increasingly prevalent due to lifestyle changes and increased life expectancy, significantly impacting the quality of life of patients and their partners. The 2018 American Urological Association guidelines emphasize shared decision-making, encouraging discussion of all treatment options. While many men initially choose less invasive therapies-such as oral medications, intraurethral alprostadil, or intracavernous injections-the guidelines support starting with any option, including penile prosthesis. Of note, over 25,000 penile implants are performed annually in the US. This review aims to bridge the knowledge gap by covering indications, types, imaging protocols, normal imaging appearances, and complications of penile prostheses.
