When an infection causes inflammation in the urethra, it is called urethritis. Infections that inflame the bladder are called cystitis. Infections that inflame the kidneys are called pyelonephritis.
The primary cause of urinary tract infections is bacteria. Sometimes, the formation of stones or tumors in the kidneys can cause a blockage in the urinary tract, which puts people at risk of developing a urinary tract infection. Sometimes, other diseases result in urinary tract infection. Urinary tract infection occurs about 10 times more often in women than in men, although infants of both sexes contract the disease at about the same rate.
Urethritis
Urethritis usually is not the result of a urinary tract infection but arises from a sexually transmitted disease such as a chlamydial infection. The main symptom of urethritis is a burning sensation during urination. The condition can be diagnosed with a urine test. Urethritis that is not treated can cause blockage and scarring in the urethra.
Cystitis>
When the bladder becomes inflamed from bacteria, a person with cystitis will have a burning sensation during urination. The condition also causes a person to feel the need to pass urine often. Low back pain, mild fever, a tired feeling, and blood in the urine sometimes also are present in cystitis, particularly if the kidneys also are involved.
Pyelonephritis
A urinary tract infection that spreads to the kidneys can be quite serious. The infection needs to be treated properly to avoid any permanent damage to the kidneys. Some symptoms that may be present in kidney infection are back pain, pain in the lower abdomen, fever, chills, nausea, and vomiting.
How Are Urinary Tract Infections Treated?
First a diagnosis is made, which might be done by procedures that include examining the urine and sending a sample to the laboratory to identify the bacteria. In some cases, doctors use x-ray, ultrasound, and other methods to diagnose urinary tract disease. Antibiotics may be prescribed to fight the bacterial infection.
How Can Urinary Tract Infections Be Prevented?
Practicing good hygiene can help prevent urinary tract infections. It is important to keep the genital, urinary, and anal areas of the body clean. Wiping the rectum separately from the urinary tract opening is important to avoid spreading fecal matter to the urethra, which can cause infection, particularly in females. Urinary tract infections also can be spread through sexual activity; avoiding risky sexual practices will reduce the chances of contracting a urinary tract infection.
