Urine Collection

09 January 2013

How is urine collected whilst it is draining from my indwelling urethral or suprapubic catheter?

As your indwelling catheter  continually allows your bladder to be emptied, an external urine collection bag is attached to it (See figures 4 & 5).  There are 2 types of collection bags available, basically, small and large.
 
The small leg bag is available in 3 capacity sizes depending on your needs and preferences i.e. 350ml, 500ml and 750ml. These bags are also available in long tube (mostly worn by males but not always) or short tube (worn by females only) again depending on personal preference, clothing, lifestyle and urinary output (See figure 10).
 
Note:  you should empty your urine drainage bag (whichever size) frequently enough to maintain urine flow and prevent backflow of urine.
 
For night time drainage a larger disposable drainable or non-drainable bag should be used that can be easily attached to the leg bag to create a continual circuit and increase urinary collection capacity. 
 
Occasionally, larger bags with a drainage tap at the bottom may be used for day and night use if leg bags, for various reasons, are not used (See figure 11) .

Together, the catheter, leg bag and night bags form a continuous circuit known as a total ‘closed link’ drainage system which prevents bacteria getting into the system, thereby reducing the risk of infection. The night drainage bag should always be attached to a supporting stand (See figure 12).

How do I attach the night drainage bag?
  1. Wash your hands thoroughly noting the areas frequently missed and put on gloves. 
    Note: If someone is undertaking the procedure for you ask them to wash their hands and put on the gloves. 
  2. Remove protective cap from the disposable, single use, non drainable/drainable 2 litre night bag
  3. Insert night bag connector firmly into the outlet drainage tube of the leg bag.
  4. Remove leg bag fixation straps or leg bag support sleeve to allow free drainage of urine.
  5. Open leg bag tap or valve tap to allow urine to flow into the 2 litre non-drainable/drainable collection bag.
  6. Secure the 2 litre non-drainable/drainable night bag on to a supporting stand (See figure 12) and ensure that it is positioned lower than the bladder to assist free drainage and prevent backflow of urine.
  7. Ensure that the catheter is never pulled by any drainage bag.
 
 
How do I disconnect the night drainage bag?
 
  1. Wash your hands thoroughly (See Figures 13 & 14) and put on gloves.
  2. Note: If someone is undertaking the procedure for you ask them to wash their hands and put on the gloves.
  3. Close the tap on the leg bag or on the catheter valve.
  4. Disconnect the non-drainable/drainable urine collection bag from the leg bag or catheter valve.
  5. Empty the urine from the bag and discard as instructed by your District Nurse or Continence Advisor. Usually, this is in your household dustbin.
  6. Secure the leg bag on to the thigh or calf using fixation straps or a leg bag support sleeve.

 

How often should I change my leg bag?
 
You should change your leg bag every 5-7 days according to manufacturer’s instructions.  You can do this yourself providing you wear a new pair of clean non-sterile gloves
