Pyelonephritis is a non-contagious bacterial infection involving the kidneys. It is more common in females of all ages, but can occur in both sexes. Acute kidney infections in males of any age often may indicate a serious underlying disease. In men who develop kidney infections, a search for disorders such as tumors, bladder obstruction or prostate disorders should be made.
Causes of Pyelonephritis
Pyelonephritis is caused by bacteria (most commonly Escherichia coli) which invade one or both kidneys and may begin in the bladder. The most common sources of bacterial infection are: vigorous sexual activity in women. This allows bacteria to enter the urethra and bladder where they can migrate up to the kidneys. Infections elsewhere in the body that travel to the kidneys through the bloodstream or lymph glands can occur. Any blockage or abnormality of the urinary system, caused by a varied arrays of disorders including stones, obstructions, bladder dysfunction from nerve diseases, tumors or congenital abnormalities, catheters, tubes or surgical procedures used for other medical conditions and the use of bubble bath, especially in young girls, can all produce pyelonephritis.
Signs and Symptoms of Pyelonephritis
Pyelonephritis produces the sudden onset of symptoms that include fever, shaking chills, painful urination, frequent urination, cloudy urine or blood in the urine. Low back pain and flank pain are frequently present on one or both sides and can be quite severe. There may be abdominal pain in the upper abdomen or it may radiate into the midline lower abdomen. Frequently, there is marked fatigue. Acute kidney infections in young children and in the elderly may not have as specific of symptoms as others.
