What complication might arise from a urinary tract infection that goes untreated?

A urinary tract infection (UTI) that remains untreated has the potential to ascend the urinary tract, leading to more severe complications. One of the most significant risks is the development of pyelonephritis, which is an inflammation of the kidney, commonly due to a bacterial infection that spreads from the bladder.

Pyelonephritis can cause symptoms such as fever, chills, flank pain, and can lead to serious complications if not addressed promptly, including kidney damage or sepsis. The kidneys are vital organs responsible for filtering waste from the blood and producing urine, so infections here require immediate medical attention to prevent further health issues.

Understanding the journey of a UTI and its potential to compromise kidney health highlights the importance of early detection and treatment, emphasizing why recognizing pyelonephritis as a consequence of an untreated UTI is crucial in emergency medicine and patient care.
