1) To describe our imaging protocol for evaluation of penile prostheses with emphasis on CT and MRI. 2) To illustrate complications and malfunctions including migration with proximal crural perforation, aneurysmal dilatation of the corporal cylinders, penile distortion and deviation, cylinder buckling, and post-operative infection.

Erectile disfunction (ED) is the most common male sexual problem affecting up to 30 million men in the USA. The penile prostheses are an effective option for ED patients who do not respond to oral medication or who have contraindications to its use with 12,000 devices being placed in 2001. These prostheses include malleable rods, mechanically positionable rods and inflatable cylinders with the reservoir in the abdomen and the pump in the scrotum. The multi-component inflatable penile prosthesis (MIPP) is the most frequently used consisting of 3 components: 1) a pair of cylinders (inserted into the corpora cavernosa), 2) a pump for cylinder inflation and deflation and 3) a reservoir filled with sterile saline. The use of saline instead of radiopaque contrast material to fill the components of the prosthesis has limited the utility of conventional radiology for post-operative evaluation. CT and MRI have replaced conventional radiology for imaging of MIPP complications and malfunctions.
