Transurethral microwave thermotherapy

Okay kiddo, have you ever heard of the word microwave? It's a type of heat that can heat up your food quickly. Now, just like how microwaves can heat up your food, doctors can use a special type of microwave to help people who have problems peeing because of their prostate.

You know how when you need to pee, the pee comes out of your private parts? Well, sometimes for grown-ups, their pee can't come out easily because their prostate is too big. The prostate is a little organ in their body that is near where their pee comes out, and it can get bigger as they get older.

So, doctors can use a little wand that they put into a grown-up's private parts to heat up the prostate with the special microwave heat. This helps to make the prostate smaller so that the pee can come out easily again. The wand stays inside for a little while to make sure the heat goes deep enough.

And that's what transurethral microwave thermotherapy is - a way to help grown-ups pee better using special microwave heat to make their prostate smaller.
