Which term is defined as the stone formed within an organ?

• A. Benign Prostatic Hyperplasia (BPH)
• B. Blood Urea Nitrogen (BUN)
• C. Calculus
• D. Chlamydia

Answer: (C)

A stone formed inside an organ is called a calculus. The word calculus refers to the stone itself and is used for stones that develop in organs such as the kidney, bladder, or other parts of the urinary tract (and even in other organs, when appropriate). The plural form is calculi. This term comes from the Latin for a small stone, and it underpins related terms like nephrolith or renal calculus for kidney stones. The other terms aren’t about stones: Benign Prostatic Hyperplasia is enlargement of the prostate; Blood Urea Nitrogen is a lab value that reflects kidney function; Chlamydia is an infection.
