Which term denotes a stone formed within an organ?

• A. Benign Prostatic Hyperplasia (BPH)
• B. Chlamydia
• C. Calculus
• D. Diuresis

Answer: (C)

Stones formed inside an organ are called calculi. This term covers stones that can develop in various organs, such as the kidneys (renal calculi) or gallbladder, and plural calculi for multiple stones. The other terms describe conditions that are not stones: benign prostatic hyperplasia is enlargement of the prostate, chlamydia is a bacterial infection, and diuresis means increased urine production. Thus, calculus is the correct term for a stone formed within an organ.
