Kidney Infection (Pyelonephritis)

Kidney infection is a urinary tract infection (UTI), usually starting from the bladder and moving upstream towards one or both kidneys. Rarely, kidney infections can cause serious health problems, but rapid treatment prevents most complications.

The symptoms of kidney infection may vary with age, and there are chills, fever, urination with pain, and so on. Kidney infections are caused by bacteria or viruses infecting the bladder and moving upstream and infecting one or both of the kidneys.

Healthcare workers will diagnose kidney infections using your medical history, physical examination and examination. Depending on age, sex, response to treatment, a specific test is used for diagnosis of kidney infection.

Your doctor can treat your kidney infection by taking antibiotics. Even if you feel better, be sure to drink all medicine.

If you have a kidney infection, please drink plenty of water to help wash out the urinary tract bacteria. If you have renal insufficiency, you should not drink that much moisture. Please discuss the amount of liquid that matches you with your health care professional.

Other components of the National Diabetes Gastroenterology Institute for Nephrology (NIDDK) and the National Institutes of Health (NIH) are conducting and supporting research on many diseases and conditions.

The urinary tract is a human urinary system used to remove urine, consisting of excrement and extra moisture. In order to have normal urination, all body parts of the urinary tract must work together in the correct order.

Your kidneys keep your blood makeup stable and your body works well. Every day, two kidneys filter the blood to remove waste and extra moisture and make the body look like urine.

Vesicoureteral reflux disease (VUR) is a problem in children with UTI. (See the "Risk Factors" section of this report.) VUR can cause kidney infections (pyelonephritis) that can cause kidney damage. If urinary reflux is not serious, the child may solve this problem without kidney damage. For children with severe or infected VUR, the two treatments are long-term antibiotics or symptomatic surgery to prevent infection. However, the advantages of these methods are controversial. Current guidelines suggest that antibiotics are not really useful in preventing recurrent UTI in children, and it is suggested that VUR itself does not significantly increase the risk of recurrent UTI.

Recurrence relapse is a rare form of recurrent UTI. UTI will recur within 2 weeks after the first episode of treatment and will be diagnosed with treatment failure. Recurrence usually occurs in relation to kidney infection (pyelonephritis) or kidney stones, structural abnormalities, or male chronic prostatitis. Asymptomatic UTI (also called asymptomatic bacteriuria) refers to a person who has no symptoms of infection but who has many bacteria colonizing the urinary tract. This condition is harmless to most people and increases the risk of continuing symptomatic urinary tract infections, but it seldom persists.

The lower UTI, a more common type, affects the lower part of the urinary tract, the urethra, and the bladder. Urinary tract infection is called urethritis and bladder infection is called cystitis. When the kidney called pyelonephritis is infected, this is the upper urinary tract infection because the kidney is the highest part of the urinary tract. The design of the human body makes it easy to obtain bacterial urinary tract infections as the infection comes from the outside through the urethra. Bacteria in the reproductive area may enter the urethra or the urinary tract. Or, after going to the toilet, you may enter the urethra or urinary tract due to swab, sexual activity, or unsanitary condition. When bacteria enter the urethra, the body attempts to fight it, but sometimes the immune system can not do this, bacteria multiply and cause infection.
