Pyelonephritis is a medical condition in which the kidneys become inflamed due to a bacterial infection. It is a type of urinary tract infection (UTI) that affects one or both kidneys. Pyelonephritis is usually caused by bacteria entering the kidneys through the urinary tract. The condition is more common in women than in men and can occur at any age.
Symptoms of pyelonephritis may include:
- high fever,
- back pain or flank pain (pain in the side of the body, just below the ribs),
- nausea and vomiting,
- urinary urgency or frequency,
- pain or burning during urination,
- cloudy or strong-smelling urine.
If you suspect you may have pyelonephritis, it is important to seek medical attention promptly. Treatment typically involves a course of antibiotics to clear the infection and may also include pain medication and fluids to prevent dehydration. Without prompt and proper treatment, pyelonephritis can lead to serious complications, such as kidney damage and sepsis.
