Kidney infections belong to the family of infections in the urinary system called Urinary Tract Infections (UTIs). Urinary tract infections (UTIs) are bacterial infections in the body’s urinary system — the bladder, kidneys, ureters, and urethra. In the kidneys, the infection is called pyelonephritis; in the bladder, it is called cystitis.
Urinary tract infections are common in women. Children with UTIs may show different symptoms than adults. It occurs when bacteria enter your urinary tract through the tube that carries urine from your body and begin to multiply. Because women have a shorter tube that carries urine from the bladder (urethra), urinary tract infections are more common in women.
Here are the factors that increases the risk of having urinary tract infection:
- Sexual intercourse, by the introduction of the bacteria from outside to the urinary system.
- Pregnant women, because of slower transit of urine from the ureter due to increased pressure caused by the enlarging uterus.
- Kidney stones that will cause obstruction to the flow of urine.
- Bladder catheters that can act as a vehicle for the bacteria to gain access to the urine inside the bladder.
Kidney infection requires immediate medical attention because it may damage the kidneys or spread the bacteria in the blood stream if not treated properly.
