Which term denotes a stone located anywhere along the ureter?

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

Answer: (A)

Think in terms of location-based naming for urinary stones. A stone that is found anywhere along the path of the ureter is called a ureterolith. This term pinpoints the structure involved—the ureter—and identifies the stone itself, regardless of where along the ureter its located. A nephrolith is a kidney stone, so it isn’t describing a stone in the ureter. A cystolith is a bladder stone, not in the ureter. Ureterolithiasis refers to the condition or presence of stones in the ureter (the disease state), not to a single stone itself. Therefore, ureterolith is the best term for a stone located anywhere along the ureter.
