Lower urinary tract infection includes which parts?

• A. Kidneys
• B. Bladder and urethra
• C. Ureters
• D. Prostate

Answer: (B)

The main concept here is anatomy of the urinary tract and how infections are classified by location. A lower urinary tract infection refers to infections of the structures at the base of the urinary system—the bladder, where urine is stored, and the urethra, the tube that carries urine out of the body. In contrast, infections of the kidneys or the ureters are considered upper urinary tract infections. The prostate is not a urinary tract structure; prostatitis is a separate condition that can occur but isn’t part of the lower urinary tract. Therefore, the parts involved in a lower urinary tract infection are the bladder and the urethra.
