Knowledge For Urine Drainage Bag

August 15,2023

Urine drainage bags collect urine.

Your bag will attach to a catheter (tube) that is inside your bladder. You may have a catheter and urine drainage bag because you have urinary incontinence (leakage), urinary retention (not being able to urinate), surgery that made a catheter necessary, or another health problem.


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. The leg bag is attached to your leg and allows you to move around more easily. The biggest difference between an overnight drainage bag and a urinary leg bag is the over-all size of the product. The other important difference is that a leg bag is meant to be worn and an overnight bag is meant to hang next to your bed while you are sleeping or resting.


Most bags are made of plastic and some have a fabric backing for comfort against the skin.

They have a tube emerging from the upper side of the bag that connects to the funnel end of a catheter or sheath. At the bottom of the bag is a small tap or valve to allow emptying. Always keep the drainage bag below the level of your bladder. This will help keep urine from flowing back into your bladder. Empty your bag into the toilet at least two or three times a day, or when it is a third to half full. Follow these steps for emptying your bag: Wash your hands well. Keep the bag below your hip or bladder as you empty it. Urinary drainage bags must be discarded every seven (7) days from first use when: • switching from a leg bag to a large drainage bag; disconnecting the drainage bag from the catheter; and • the bag is leaking, damaged, discolored, stiff and brittle or a strong odor persists after cleaning.


Drainage bags come in different sizes and can be worn on the leg i.e. thigh/calf or on the belly for suprapubic catheters. Drainage bags can hold between a quarter pint and two pints of liquid, depending on the size of the bag. Empty your leg bag at regular intervals to avoid it becoming too full and heavy, which may pull on your catheter. This should occur every 2 to 3 hours or when the bag is about half to three-quarters full.
