A urinary tract infection, or “UTI,” is an infection that can occur in your kidneys, in the tubes that take urine from your kidneys to your bladder, or in your bladder.
You have an indwelling catheter (tube) in your bladder. "Indwelling" means inside your body. This catheter drains urine from your bladder into a bag outside your body.
Many types of bacteria or fungi can cause a catheter-related UTI. In general, they are more resistant to common antibiotics than bacteria causing other types of UTIs.
Common reasons to have an indwelling catheter are:
During a hospital stay, you may have an indwelling catheter:
Other symptoms that may occur with a UTI:
*Often in an elderly person, mental changes or confusion are the only signs of a possible urinary tract infection.
Urine tests will check for infection:
Your doctor may recommend an ultrasound or CT exam of your urinary system.
Because there is a risk that your infection may spread to your kidneys, antibiotics are almost always used to treat a UTI.
Your catheter will need to be changed when you have a UTI.
You will need more fluids to help flush bacteria out of your bladder.
After you have finished your treatment, you will have another urine test to make sure the bacteria are gone.
UTIs related to catheters can be harder to treat than other UTIs. Having many infections over time may lead to kidney damage or kidney stones and bladder stones.
If a UTI is not treated, you may develop kidney damage and more severe infections.
Call your health care provider if you have:
If you have an indwelling catheter, you must do these things to help prevent infection:
Your health care provider might advise you to drink more fluids every day. This is not healthy for everyone, so talk with your doctor before you do this.
Your health care provider may prescribe a low-dose antibiotic to take every day to keep bacteria from growing in your catheter.
