What is Urinary catheter?
A urinary catheter is a thin, flexible tube inserted into the bladder to drain urine, used when someone can't empty their bladder normally, needs precise urine output monitoring, or requires bladder drainage after surgery. Catheters can be temporary or, in some cases, longer-term.
Proper catheter care is important to prevent complications such as infection or blockage, and most people or their carers can be taught how to manage a catheter safely at home if needed long-term.

Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Keep the catheter and drainage bag clean.Regular hygiene around the catheter site and drainage system reduces the risk of infection.
- 2Keep the drainage bag below bladder level.This uses gravity to help urine flow and prevents it flowing back toward the bladder.
- 3Drink plenty of fluids unless advised otherwise.Good hydration helps keep urine flowing well and reduces the risk of blockage.
- 4Secure the catheter tubing properly.Using a leg strap or holder as advised prevents pulling or dislodging, which can cause discomfort or injury.
- 5Know the signs of infection or blockage.Being aware of what to watch for means you can get help quickly if a problem develops.
