A urinary catheter is a tube that is inserted into your bladder to drain urine. A catheter may be necessary for a number of reasons, including an inability to empty your bladder, a pending surgical procedure, or a need to monitor precisely how much urine your body is making. A Foley catheter has a balloon that is inflated once the catheter is placed in the bladder. The balloon keeps the catheter in place and prevents it from leaving the bladder. When inserted correctly, the balloon does not cause any discomfort; however, when a catheter is inserted blindly, accidental inflation of the balloon in the urethra can cause severe pain and trauma and may require surgery to be corrected.
