Which term describes the presence of stones in the kidney?

• A. Nephrolith
• B. Ureterolith
• C. Nephrolithiasis
• D. Cystolith

Answer: (C)

Nephrolithiasis describes the presence of stones in the kidney. The parts tell the meaning: nephro- means kidney, lith means stone, and -iasis denotes a condition or abnormal state. Put together, nephrolithiasis is the condition of kidney stones. A single kidney stone is called a nephrolith, a stone in the ureter is a ureterolith, and a bladder stone is a cystolith. If stones occur anywhere in the urinary tract, the broader term is urolithiasis.
