I don't mean to freak you out, but this was my primary fear heading in too and it was by far the worst thing of the surgery experience. When I woke up from surgery it was the first thing I noticed. It hurt when I walked. Taking it out might have been the worst 4 or 5 seconds of pain I have ever felt. And it hurt like hell to pee the first few times after taking it out. And something very strange happended .... I farted out of it a few times after when I would pee.
That being said it was worth it although I didn't really see the need for it. I was up and walking a couple hours after surgery.
