Have you already chosen a type of catheter?
Always wash your hands before using a catheter. You can learn to use a catheter in different ways, depending on which method you find easiest. You can insert a catheter by sitting down or sitting on the toilet, when standing or by putting one foot up onto the toilet to enable you to insert it more easily. If you have difficulty finding where to insert the urethra, you can use a mirror to see where your urine comes out.
To remove the catheter, gently twist it and pull down. Don’t worry if you feel uncomfortable doing this for the first time, as with practice, this will become easier.
