radical perineal prostatectomy
[rad-ick-uhl pair-uh-NEE-ul pros-tuh-TECK-tuh-me]
surgery to remove the prostate through an incision in the perineum (skin behind the testicles). This approach is used less often than others, in part because it makes it harder for the surgeon to spare the nerves that control erections.
