Penile Prosthesis/Implant Surgery
Component Inflatable prostheses consist of a pair of inflatable cylinders, a reservoir, a pump, and tubing to connect these components.
The cylinders are implanted within the corpora, the pump within the scrotum, and the reservoir behind the rectus abdominis muscle in the perivesical space.
Compressing the pump achieves active transfer of fluid from the reservoir into the cylinders.
Pressing a release valve on the pump allows passive flow of fluid back to the reservoir and achieves detumescence. Significant design alterations over the years since their first introduction have reduced mechanical failures and improved safety and efficacy of these devices such that they now compare favorably with non-inflatable rod-type devices.
Recent multi-institutional 2-year follow-up studies have shown an approximately 9% risk of morbidity, 7% risk of revision or explantation, and a 2.5% risk of mechanical failure in one brand of the inflatable three-piece prostheses.
Satisfaction rates of 80% or higher in terms of confidence and intecourse ability as well as prosthesis function and rigidity were reported in the same study.
