What is a Urinary Tract
Infection?
A UTI is an infection occurs when bacteria
invade the urinary tract and multiply.
It is the second most common infection in
the body.
Woman are especially prone to UTI’s for an
unknown reason. 1 in 5 woman will develop a
UTI during their lifetime
UTI’s are not as common in men but can be
More serious when they occur
What Causes a Urinary Tract
infection?
Urine is usually sterile, but an infection
can occur when bacteria from the digestive
tract cling to the opening of the urethra
and begin to multiply.
Most UTI’s arise from the type of bacteria
called Escherichia coli, or E. coli, which
normally lives in the colon.
Microorganisms called Chlamydia and
Mycoplasma may also cause UTI’s in
both men and women.
Further Infection
Usually, UTI’s are not very serious and are
limited to the urethra. This is called urethritis.
If bacteria move to the bladder and multiply,
a bladder infection, called cystitis, results.
If the infection is not treated promptly,
bacteria may then travel further up the ureters
to multiply and infect the kidneys. A kidney
infection is called pyelonephritis.
What are the Symptoms of a
Urinary Tract Infection?
•Pain or a burning feeling during urination
•A feeling of urgency, or feeling the need to
urinate frequently
•An altered appearance of the urine, either
bloody (red) or cloudy (containing pus)
•Pain or pressure in the rectum (men) or in
the area of the pubic bone (women)
•Passing only a tiny amount of urine even
when the urge to urinate is strong
How is a Urinary Tract
Infection Diagnosed?
Diagnosis is based on the patient’s symptoms,
medical history, medications, habits and lifestyle.
A UTI is confirmed by a physical examination and
lab tests.
The doctor may perform a urine dipstick, which will
give results in a matter of minutes.
A doctor will sometimes test a “midstream” urine
sample for pus and bacteria. A sensitivity test
Helps determine the exact bacteria causing the
Problem.
More Testing
In another lab test, the
urinalysis test, the urine
is examined for white
blood cells and bacteria.
Then the bacteria are
grown in a culture and
tested against different
antibiotics to find the best.
Blood tests are required
only if kidney infection
is suspected.
How is a Urinary Tract
Infection Treated?
UTI’s are treated with antibacterial drugs.
The choice of drug and length of treatment
depend on the patient's history and the urine
test results. The sensitivity test is especially
useful in helping the doctor select the most
effective drug.
Also:
• Drink plenty of water
• Quit Smoking
• Avoid spicy foods, coffee, and alcohol
• Use a hot water bottle and pain medication
to ease pain
Types of Drugs Used to Treat
Urinary Tract Infections
The drugs most often used to treat uncomplicated UTIs are:
•Trimethoprim
•Trimethoprim/ Sulfamethoxaole
•Amoxicilin
•Nitrofurantin
•Ampicillin
Often, a UTI can be cured with 1 or 2 days of treatment if the
infection is not complicated by an obstruction or other disorder.
