Drainage Bags

A drainage bag collects urine from a catheter or penile sheath. Normally there is a tube which connects the catheter or sheath to the drainage bag. With a catheter everything should be sterile.

Drainage bags come in different sizes and can be worn on the leg i.e. thigh/calf or on the belly for suprapubic catheters.


Leg bags can be worn with straps or supported in a special garment or holster, or in a pocket sewn into your normal clothing. Belly bags which are used forsuprapubic catheters, fasten around the waist generally by a woven belt or similar. The bag will contain the urine until it is emptied – a tap at the bottom of the bag lets out the urine. “The closed system” leg bags should be sterile and changed weekly.


The night drainage bag should be held on a night bag stand so that it is kept off the ground. It should also be positioned to let the urine flow down to the night bag. Night bags are disposed of on a daily basis in the morning.

The nurse who carried out the catheterisation should ensure that all the correct equipment is prescribed so that extra stock is not needed, except for repeat prescriptions when stock runs low.

As with all products, try different drainage bags until you find one which suits you.
