Urinary Tract Infection
What is a urinary tract infection?
A urinary tract infection (UTI) is an infection of the
bladder and sometimes the kidneys. If the bladder is
infected, it is called cystitis. If the kidneys are
infected, it is called pyelonephritis. It is important to
treat UTIs so that the kidneys are not damaged.
Various symptoms are possible:
- painful urination
- an urgent need to urinate
- frequent urination
- daytime and nighttime wetting
- dribbling
- foul-smelling urine
- fever
- stomachaches (especially lower abdomen)
- vomiting.
What is the cause?
Urinary tract infections are caused by bacteria. The
bacteria enter the bladder by traveling up the urethra. In
general, the urethra is protected, but if the opening of the
urethra (or the vulva in girls) becomes irritated, bacteria
can grow there. Common irritants are bubble bath and
shampoos. Sexual intercourse or careless wiping after a
bowel movement might also cause irritation. A rare cause of
UTIs (1% of girls and 5% of boys) is obstruction of the
urinary tract, which results in incomplete emptying of the
bladder.
How long will it last?
With treatment, your fever should be gone and symptoms
should be better by 48 hours after starting the antibiotic.
The chances of getting another UTI are about 50%. Read the
advice on preventing UTIs to decrease your risk.
How can I take care of myself?
- Antibiotics
Your antibiotic is _________________________________.
Your dose is ________ taken ____ times a day during
waking hours for ____ days. This medicine will kill the
bacteria that are causing the UTI.
Try not to forget any of the doses. Take the medicine
until all the pills are gone. Even though you will feel
better in a few days, take the antibiotic for the full 10
days to keep the UTI from flaring up again.
- Extra fluids
Drink extra fluids to help clear the infection.
- Fever and pain relief
Take acetaminophen (Tylenol) or ibuprofen (Advil) for the
painful urination or for fever over 102°F (39°C).
- Medical follow-up
Two days after you begin antibiotics, it is important to
contact your health care provider to find out the results
of the urine culture and make sure that your infection is
responding to the antibiotic.
About 2 weeks after your initial visit your provider will
want to see you for another urine culture. Because the
chances are high that you will develop a second infection
(50% of cases), your provider will probably also want to
check your urine 1, 4, and 12 months after the first
infection has cleared up.
- Instructions for collecting a midstream, clean-catch
urine specimen at home
If you are asked to bring a urine sample to your
physician's office, try to collect the urine when you
first urinate in the morning. Use a jar and lid that
have been sterilized by boiling for 10 minutes.
For Girls: Wash the genital area several times with a
clean washcloth and warm water. Sit on the toilet seat
with your legs spread widely so that the labia (skin
folds of the vagina) don't touch. Start to urinate into
the toilet and then place the clean container directly in
line with the stream of urine. Remove it after you have
collected a few ounces but before you stop urinating.
(The first or last drops that come out of the bladder may
be contaminated with bacteria.)
Keep the urine in the refrigerator until you take it to
your provider's office. Try to keep it chilled when you
bring it to the office (that is, put the jar in a plastic
bag with some ice).
How can I prevent a urinary tract infection?
- Urinate at least every 3 to 4 hours during the day and
don't "hold back."
- Urinate after baths.
- Sexually active young women should urinate after
intercourse.
- Wipe correctly from front to back, especially after a
bowel movement.
- Don't put bubble bath, shampoo, or other soaps into the
bath water. Don't let a bar of soap float around the
tub.
- Don't become constipated. Try to have a BM every day.
- Drink enough fluids each day to keep the urine
light-colored.
When should I call my health care provider?
Call IMMEDIATELY if:
- You start having back pain.
- You start feeling very sick.
Call during office hours if:
- Fever or painful urination lasts more than 48 hours after
you start taking an antibiotic.
- You have other concerns or questions.
