when i had my gallbladder removed i went down to theatre with my own knickers on and a hospital gown.
i didnt have a catheter but i can agree that they remove all underwear and then put them back on as when i went down there i had pink pants with a little black bow on the front, when i awoke the bow was nicely placed on my butt.
