A bladder, or urinary, catheter is a thin, hollow tube inserted into your urethra and bladder. The catheter drains urine from your bladder into a bag. Two common types of catheters are intermittent and indwelling catheters.

You don’t need to do anything to prepare for this procedure.
Catheters are usually inserted into the urethra while you are lying on your back. Your genital area will be cleaned with antibacterial soap. Your healthcare provider will use a sterile process to put in the catheter. You may feel some discomfort and when the catheter is inserted. Rarely, there may also be some bleeding.
A bag will be attached to the catheter to collect urine. If the catheter is placed to get a urine sample, once the urine has been collected, the catheter will be removed. If the catheter needs to stay in place for continued emptying or checking of your kidneys or water balance, then a tiny balloon (which you will not feel) will be expanded inside the bladder to hold the catheter in place. The tubing attached to the collecting bag will be taped to your leg.
If the catheter did not have to stay in, you may feel some burning the next few times you urinate. The burning is from irritation of the urethra by the catheter. If the catheter is left in, you may have an irritating feeling that you need to urinate, even though your urine is passing into the collecting bag continuously as your kidneys produce it.
While you have the catheter, it is important to keep the bag below your pelvic area. This helps prevent infection by keeping the urine in the bag and tube from draining backwards into the bladder. You may have a bag that can be strapped to your leg and fits under slacks or dresses so that it does not show.
