Urine will drain through your catheter into the toilet or a special container. Your doctor will show you how to use your catheter. After some practice, it will get easier.
Sometimes family members, a school nurse, or others may be able to help you use your catheter.
Catheters and other supplies can be bought at medical supply stores. Your doctor will give you a prescription for the right catheter for you. There are many different types and sizes. Other supplies may include towelettes and lubricant such as K-Y Jelly or Surgilube. Do not use Vaseline (petroleum jelly).
Ask your doctor how often you should empty your bladder with your catheter. Usually it's every 4 to 6 hours, or 4 to 6 times a day.
Always empty your bladder first thing in the morning and just before you go to bed at night. You may need to empty your bladder more frequently if you have had more fluids to drink.
Avoid letting your bladder get too full. This increases your risk of infection or other complications.
