What is self-catheterisation?
Self-catheterisation means that you insert a small, flexible plastic tube into the bladder. The urine flows out through this tube which is then removed and washed. By emptying the bladder regularly in this way, you will prevent a build-up of stagnant urine and should feel more comfortable. You will also be keeping the kidneys and bladder healthy by preventing urinary infections. Some people find that they have less difficulty preventing themselves becoming wet using this technique.

What equipment do I need?
- A catheter – supplied at first by the outpatient clinic and then available to order on prescription from your GP
- Baby wipes
- Shaving mirror and a good light are helpful, particularly at first
- A bottle, dish or plastic box to catch the urine
How do I do it?
- Sit on a towel with a plastic sheet just underneath or lie on the bed if you prefer
- Remove your pants and tuck other clothing out of the way
- Wash your hands thoroughly
- Lie on your back, comfortably propped up with your knees wide apart. Using the light and mirror to help you, find the opening of the urethra which is in front of the vagina and behind the clitoris
- If it is difficult to see the hole, draw the labia forwards and upwards whilst separating them with your fingers. It is also possible to feel the urethra which is like a small pit on a sensitive mound
- Clean inside the labia from front to back using baby wipes
- Hold the catheter two inches from its tip and insert it until urine flows (usually needs insertion for two to three inches)
- If no urine comes out, the catheter is probably in the vagina. This will do no harm and simply means taking it out and looking again for the urethra, just further forwards
- When urine stops flowing, insert the catheter a little further and turn it gently to obtain any remaining urine
- Withdraw the catheter slowly
- Rinse the catheter under running water, dry on a clean tissue and store in a clean plastic bag open to the air if possible
