What to do if…
your urinary catheter has stopped draining and you feel bladder pressure building

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

If your catheter has stopped draining and you feel bladder pressure building, do a very quick check for a kink, closed valve, bag position, or full bag, then get urgent NHS help now. Contact your catheter service, community nurse, GP out-of-hours, NHS 111 where available, or your local NHS urgent-care number.

Do not do these things

  • Do not pull, cut, clamp, or remove the catheter yourself.
  • Do not press hard on your lower tummy to force urine out.
  • Do not flush or irrigate the catheter unless you have been trained and specifically told to do this for your catheter.
  • Do not disconnect the catheter system unless you have been told to do that as part of your normal care.
  • Do not rapidly drink large amounts to “push it through” while your bladder already feels full or painful.
  • Do not wait for hours if no urine is draining and pressure or pain is building.

What to do now

  1. Sit or lie somewhere stable where the catheter and bag are not being pulled. Keep the bag where you can see it.

  2. Do a quick catheter check for no more than a minute:

    • Make sure the drainage bag is below bladder level.
    • Check the tubing is not kinked, twisted, looped, trapped under you, or pulled tight.
    • If you use a catheter valve, check it is open.
    • Check the bag connection is secure without pulling it apart.
    • If the bag is full or heavy, empty it using the tap.

  3. Change position once, gently. Stand if safe, straighten your leg, or roll slightly to one side. Keep the tubing straight and the bag below bladder level.

  4. If urine still does not drain and pressure is building, contact urgent help now. Use the fastest route you have:

    • your catheter service, continence service, urology contact, community nurse, or district nurse
    • your GP out-of-hours service
    • NHS 111 where available, or your local NHS urgent-care number

  5. Say clearly: “My urinary catheter has stopped draining, my bladder feels full or pressured, and I think it may be blocked.”

  6. Seek emergency help if you are becoming seriously unwell. Call 999 if you have severe or unmanageable pain, confusion, collapse or feeling you may collapse, severe weakness, serious breathing problems, or you cannot get to urgent help safely. Go to the nearest emergency department if urgent NHS advice tells you to, or if you cannot access urgent advice and the pain or pressure is severe or worsening.

  7. While waiting for help, keep the bag below bladder level, keep the tubing straight, and avoid tugging. Note roughly when it last drained and whether you can see blood clots, debris, or new leakage around the catheter.

What can wait

  • You do not need to work out why the catheter stopped draining right now.
  • You do not need to decide whether you did anything wrong.
  • You do not need to clean, change, or reorder equipment beyond normal hand hygiene and emptying a full bag.
  • You do not need to plan long-term catheter changes or prevention until urine is draining again and you have been assessed.

Important reassurance

A catheter can stop draining even when you have done normal care correctly. Simple things such as position, kinks, a full bag, a closed valve, or debris can sometimes affect flow, and the safest next step is prompt help rather than trying forceful fixes yourself.

Scope note

These are first steps only for the moment a catheter stops draining with pressure or pain building. Later decisions about catheter changes, infection checks, supplies, or prevention may need help from a clinician or catheter service.

Important note

This guide is general information and is not medical advice, a diagnosis, or a substitute for urgent clinical care. A catheter that stops draining with bladder pressure or pain may need prompt assessment and treatment by a trained professional.
