Catheter Associated UTI

Overview, Causes, & Risk Factors | Symptoms & Signs | Diagnosis & Tests | Prevention & Expectations | Treatment & Monitoring

A catheter associated urinary tract infection (UTI) is an inflammation or infection of the bladder. This type of UTI is caused by using a urinary catheter. A urinary catheter is a thin tube that is placed through the urethra to drain urine from the bladder.

A urinary catheter is used:

  • during and after some surgeries
  • to collect a urine specimen
  • to monitor accurate urine output
  • when the bladder isn't working due to illness or injury
  • What is going on in the body?

    When a urinary catheter is put into the bladder, there is a chance that bacteria may be introduced. This may occur if:

  • the catheter is inserted under unsterile conditions
  • bacteria spread along the outside of the tube after it is inserted into the bladder
  • The bacteria multiply in the bladder and cause a urinary tract infection. Bacteria called aerobic gram-negative rods account for most catheter-assocated UTI's.

    What are the causes and risks of the infection?

    The risk of getting catheter associated UTI are increased in:

  • females
  • older people
  • someone with an underlying illness
  • The risk increases the longer the urinary catheter is kept in place.
