A Foley catheter is a device that drains urine from your bladder into a bag. The catheter that is in your bladder has a small balloon filled with fluid to hold it in place. You may go home with a Foley catheter in place after your surgery. During the daytime, your catheter will be connected to a leg bag that attaches to your thigh. At night, you can change it to a larger bag.
Call your doctor if:
Do not go more than five to six hours with no urine flow without calling the doctor. You should have at least 100cc (ml ) in three to four hours.
