The Foley catheter is a tube that helps drain urine from the bladder. It is used by some patients who have had urological or gynecological surgery, or who have a condition that makes urination difficult. The urinary (Foley) catheter is placed into the bladder through the urethra, the opening through which urine passes. The catheter is held in place in the bladder by a small, water-filled balloon. In order to collect the urine that drains through the catheter, the catheter is connected to a bag. It is either a regular (large bag) drainage bag or a small leg bag. If you have a urinary (Foley) catheter, you will use the larger drainage bag at night while you are sleeping. You can use the leg bag during the day. Attaching or removing a leg bag The leg bag is attached to your leg and allows you to move around more easily. Because the bag is hidden under your clothes, it may also make you feel more comfortable about the catheter. To attach or remove a leg bag, you will need the following materials:
  • Clean leg bag(s).
  • Leg straps or tape.
  • Cotton balls and alcohol pads.
  • White vinegar.
  • Water and a towel.
  • Regular (large) drainage bag.
To attach or remove the leg bag:
  • Wash your hands with soap and water for 15 seconds.
  • Empty the large drainage bag. The different types of drainage bags open in different ways: a drain spout that you remove from its sleeve, a clamp that you open to the side, or an opening that you twist. Whichever method you use, be sure to not touch the tip when you let the urine flow out of the large drainage bag into the container or toilet.
  • Place a towel under the connection between the catheter and the bag.
  • Pinch off the soft rubber tube (the catheter tube) so that urine doesn't leak out.
  • Disconnect the urinary (Foley) catheter tube from the current large drainage bag with a twisting motion. Keep pinching the soft rubber tube (the catheter tube) so that urine does not leak out.
  • Be careful not to pull on the catheter. Place the old large drainage bag on the towel.
  • Prepare to place the leg bag in the catheter tube from which you just disconnected the large drainage bag. Remove the protective coating from the tip of the leg bag drainage tube. (Save this tip to use later when you change back). Clean the tip with an alcohol pad, wiping away from the opening to avoid getting the tube dirty. Insert the tip in the catheter tube.
  • Fasten the straps of the leg bag to your thigh. Secure the catheter itself to your leg with tape. Be sure to leave some slack in the catheter so that you don't put too much pressure on the bladder, urethra, and other parts of the body. Don't fasten the straps on the urine bag too tightly to your leg, as that may interfere with your circulation. If the leg strap gets dirty, wash it with soap and water.
