Which term describes the condition of having a stone in the ureter?

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

Answer: (C)

Describing stones in the urinary tract uses the suffix -iasis to denote a condition or disease state caused by their presence. When a stone is located in the ureter, the appropriate term for the condition is ureterolithiasis. This emphasizes the ongoing state of having stones within the ureter, rather than naming the stone itself.

In contrast, naming the stone itself would be ureterolith, which refers to the actual stone residing in the ureter, not the condition of having stones there. A cystolith is a stone in the bladder, and hydroureter describes dilation of the ureter often due to obstruction, not the presence of stones.
