Night Drainage Bags for Catheters


Originally published on: June 23rd, 2020. Last modified on December 15th, 2021


Hygiene is vitally important, so always wash the area around where the catheter enters your body at least once per day with soap and water to remove any encrustation or debris which may have dried to your catheter.

Leg bags and catheter valves can be used by those assessed for suitability but some users of suprapubic catheters may find the Belly Bag more useful. These are available on prescription, see your Healthcare Professional for information.

The following information will support you in attaching or disconnecting a night drainage bag.
