Detailed answer

A urinary tract infection (UTI) refers to an infection that involves any part of the urinary system, which includes the kidneys, bladder, ureters, and urethra. Most UTIs occur in the lower urinary tract, affecting the bladder and urethra. Symptoms of a UTI may include frequent urge to urinate, pain or burning sensation during urination, cloudy or bloody urine, and strong-smelling urine. If left untreated, a lower UTI can potentially progress and reach the kidneys, resulting in a kidney infection.

A kidney infection, also known as pyelonephritis, is a more serious condition that specifically affects the kidneys. It typically occurs when bacteria enter the kidneys from the bloodstream or ascend from the lower urinary tract. Common symptoms of a kidney infection include fever, pain in the back or side below the ribs, shaking chills, nausea, and vomiting. Prompt treatment with antibiotics is necessary to prevent complications that could result in kidney damage.

In summary, while a urinary tract infection can affect any part of the urinary system, a kidney infection specifically targets the kidneys and requires immediate medical attention to prevent potential complications.
