You will have a catheter in your bladder during the surgery. This will be placed after you are asleep and the majority of the time, will be removed before you wake up. On the rare occasion, your bladder may still be “sleepy” after the surgery and will not want to work right away. If you are unable to urinate on your own, the catheter may have to be reinserted and will be removed the following day. This does not happen often (but does happen).
If you have significant amounts of endometriosis over your bladder, or if you had a long surgery, you may wake up with the catheter still in your bladder just to let it rest overnight or for a few days.
