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 USA guide

Short answer

If your urinary catheter stops draining and you feel pressure like your bladder is filling, do one brief check for a kink or position problem, then call your healthcare provider, urologist, surgeon’s line, or home health nurse now. If pain is severe, you feel very unwell, or you cannot reach help promptly, go to an Emergency Department or call 911.

Do not do these things

  • Do not pull, cut, clamp, or remove the catheter yourself.
  • Do not press hard on your lower belly to try to force urine out.
  • Do not flush or irrigate the catheter unless you have been trained and specifically told to do this for your current catheter.
  • Do not disconnect the catheter from the bag unless your clinician has told you to do that.
  • Do not rapidly drink large amounts of fluid to try to make it drain when you already feel full or pressured.
  • Do not keep waiting if pressure or pain is building and little or no urine is draining.

What to do now

  1. Sit or lie down so you can move carefully without pulling on the catheter.

  2. Keep the drainage bag below bladder level, below your lower belly or hips.

  3. Check the tubing once from your body to the bag. Straighten any kinks, twists, loops, or tubing trapped under your leg or body.

  4. Check the leg bag straps. Loosen them if they are tight enough to squeeze the tubing or press into your leg.

  5. Check that the bag valve or tap is closed for collection, and if you use a catheter valve instead of a bag, check that it is open when you are trying to drain.

  6. Change position once, gently. Stand if safe, or shift your hips and legs, while keeping the bag below bladder level.

  7. If urine still is not draining and pressure is building, call your urologist, surgeon’s post-op number, primary care office, urgent nurse line, or home health nurse now. Say: “I have a urinary catheter that is not draining, and bladder pressure or pain is building.”

  8. Go to an Emergency Department or call 911 now if pain is severe or rapidly worsening, you feel faint or confused, you are vomiting, you have fever or chills, you have flank or back pain with feeling ill, or you cannot safely get to care.

  9. While waiting or travelling, keep the bag below bladder level, keep the tubing straight, avoid tugging, and note when it last drained and whether you can see debris or blood clots.

What can wait

  • You do not need to work out whether the cause is a kink, debris, a clot, bladder spasm, constipation, or infection right now.
  • You do not need to choose a new catheter type, size, or supplier right now.
  • You do not need to make a long-term prevention plan before the catheter is draining again and you have been assessed.
  • You do not need to decide perfectly whether it is “serious enough”; stopped drainage with building bladder pressure is enough reason to seek prompt medical help.

Important reassurance

A catheter can stop draining suddenly even when you have done normal catheter care. The pressure feeling is a warning sign to act, not a sign that you failed.

Scope note

These are first steps only for the moment a urinary catheter stops draining with pressure building. After the immediate problem is fixed, a clinician may need to check for causes such as blockage, infection, constipation, catheter position, catheter size, or bladder spasms.

Important note

This guide is general information, not medical advice, diagnosis, or professional care. A catheter that stops draining with a growing full-bladder feeling may mean urinary retention and may need prompt evaluation, catheter replacement, or other treatment.
