The short explanation
Some difficulty passing urine is common in the first day after delivery, because of swelling, stitches, an epidural or a long labour. But feeling the urge with nothing coming out and a hard, full lower belly can mean the bladder is not emptying, called urinary retention. This needs attention quickly, because an over-stretched bladder can be damaged and is painful. Tell the nurse or doctor on the ward now, or if you are home, go back to the hospital today. They can check with a bladder scan and, if needed, drain the bladder with a thin tube called a catheter, which usually brings immediate relief.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Retention after birth often improves within a day or two once swelling settles, but some women need a catheter for a short time. An infection, constipation or pain from stitches can contribute.
- Do not try to manage it at home by drinking a lot more water, as this can over-fill the bladder further.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell how full your bladder is or why it is not emptying. That needs an examination and a bladder scan.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is my bladder full, and does it need draining?
- Will I need a catheter, and for how long?
- Could my stitches, swelling or pain relief be causing this?
- How will we know my bladder is emptying properly again?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if you cannot pass urine and have severe belly pain, heavy bleeding, fever, or feel faint.
Get help the same day
- Tell the ward staff or return to the hospital today if you cannot pass urine or only pass small dribbles with a hard lower belly.
Raise it at a routine appointment
- Mention any ongoing bladder difficulties at your postnatal check.
