How often will I need to catheterise?
If you can’t urinate at all, you will need to catheterise 4 to 6 times a day. The amount of urine per catheterisation cannot be more than 500 ml. If you exceed this amount, you may well have to catheterise more often during the day.
If you are able to urinate but not fully empty your bladder, you will probably have to catheterise 1 to 4 times a day. This depends on the amount of urine that remains in the bladder and the advice of your doctor or specialist. This determines the best frequency of catheterisation for you.
