potency preservation
Maintenance of erectile function sufficient for sexual intercourse following radical prostatectomy with nerve-sparing technique.
Full Definition
Potency preservation refers to the retention of erectile function adequate for sexual intercourse following radical prostatectomy performed with nerve-sparing surgical techniques. Success is typically defined as the ability to achieve and maintain erections sufficient for penetration, either with or without the aid of phosphodiesterase-5 inhibitors or other erectile aids. The likelihood of potency preservation depends on multiple factors including preoperative erectile function, patient age, extent of nerve-sparing performed, tumor characteristics, and surgeon experience. Recovery of erectile function may continue for up to 24 months following surgery, with most recovery occurring within the first 12-18 months.
Usage
Usage note: Often assessed with validated questionnaires. May include aided or unassisted erections depending on study definition.
