Pyelonephritis

Pyelonephritis is a kidney infection that often begins as a urinary tract infection (UTI) and spreads to the kidneys.

Symptoms of pyelonephritis

Pyelonephritis can occur with or without a fever, but other common symptoms include pain in the side or back, nausea, vomiting, and sometimes blood in the urine.

How do you get pyelonephritis?

The infection is usually caused by bacteria that ascend from the urinary tract to the kidneys. If a UTI is not treated, it can spread and cause a more serious infection in the kidneys.

What does pyelonephritis feel like?

In addition to fever, the condition may feel like intense pain in the back or side, often accompanied by a general feeling of illness and discomfort when urinating.

Difference between pyelonephritis and urinary tract infection?

Urinary Tract Infection typically affects the urethra and bladder, with symptoms like burning during urination and frequent urination. Pyelonephritis is a more severe form where the infection spreads to the kidneys and can lead to complications if not treated.

If the doctor suspects you have pyelonephritis, you may need to provide a blood sample. This test is called a CRP test or rapid CRP, as the results are quick. In pyelonephritis, the CRP value rises rapidly, confirming ongoing inflammation.
