Background
Artificial urethral sphincters and malleable and inflatable penile prostheses (PP) are widely used in the United States. Although surgery is associated with high patient satisfaction, a multitude of complications can occur. Urologists and radiologists often work alongside each other to help identify and appropriately diagnose complications to provide timely intervention and prevent device failure before permanent damage occurs. There is a need for educational resources to help physicians from both specialties to identify and characterize common complications of implantable devices in male urethra on imaging.

Educational Goals / Teaching Points
Our objective is to review common complications of malleable PP including fracture, buckling, perforation, and distal erosion. Common complications of inflatable PP such as infection, malposition, and mechanical failure of different parts (cylinder/pump/reservoir) will also be detailed. We illustrate normal positioning of PP and discuss short- and long-term complications of PP and their clinical implications.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
In this educational presentation, we describe normal male urethral anatomy as it pertains to PP insertion, followed by imaging illustration of appropriately positioned PP components in asymptomatic patients. Early radiographic identification of complications requires a strong partnership between radiologists and urologists in imaging evaluation and clinical decision making, especially in postoperative assessment and clinical follow up. Lastly, our pictorial review of short- and long-term postoperative complications of PP highlights the appropriate use of imaging in evaluation of these complications.

Conclusion
We provide a review and a pictorial atlas of clinical and radiographic findings associated with normal placement and common complications of penile prostheses to serve as an educational resource for radiologists, urologists, and other specialists.
