Prostatectomy is a big word that means removing something called the prostate gland. The prostate is a little organ that only boys and men have, and it's located right below their bladder. The prostate helps make something called semen, which is a liquid that helps boys and men have babies.
Sometimes, the prostate can get sick or have problems that need to be fixed. If that happens, doctors might do a prostatectomy to take the whole prostate gland out of the boy or man's body.
To do a prostatectomy, doctors have to cut a little hole in the boy or man's body, usually on their belly or their private parts. Then they use special tools to carefully take out the whole prostate.
After a prostatectomy, the boy or man might have to stay in the hospital for a little while to rest and get better. Doctors will make sure that everything heals up okay, and then the boy or man will be able to go back home and get back to their normal life.
