Urinary tract infections include which of the following conditions?

• A. Infections in the urinary system including urethritis, cystitis, nephritis, and pyelonephritis.
• B. Inflammation of the bladder only.
• C. Formation of kidney stones.
• D. Infection of the kidneys only.

Answer: (A)

Urinary tract infections are infections anywhere along the urinary tract, from the urethra up to the kidneys. That means urethritis (urethra), cystitis (bladder), nephritis (kidney tissue), and pyelonephritis (kidney pelvis and tissue) are all included. So the best description covers infections at all these sites, not just one part. A statement limited to the bladder is too narrow, and an infection of the kidneys only misses infections that can involve the urethra or bladder. Kidney stones are not an infection, so they don’t define UTIs.
