Urinary infections are caused by bacteria entering your bladder. Bacteria most commonly enter your bladder through the urethra. The bacteria multiply in your bladder, either floating in the urine or attached to the bladder wall. Because your bladder and kidneys are connected, bacteria in the bladder can also invade your kidneys.
Bacteria that may be present on your hands or in the genital area can be introduced (pushed) into the urethral opening through the catheter itself. This is why effective cleaning of both the genital area and your hands are important.
It is important that you seek and follow the advice of your healthcare provider in the diagnosis and treatment of a urinary tract infection.
These are general guidelines meant to help you with typical questions. You should follow the specific instructions provided by your healthcare provider and the intermittent catheterization solution you are using.
