Which presentation is classic for urinary stones?

• A. Sudden onset flank pain with N/V, hematuria, groin radiation
• B. Gradual dull ache
• C. Fever
• D. Cough

Answer: (A)

Classic presentation: sudden, severe unilateral flank pain from ureteral colic that often waxes and wanes as the stone moves, frequently radiating to the groin. This pain is typically accompanied by nausea and vomiting, and there is often visible or microscopic blood in the urine from irritation of the urinary tract lining. This combination—acute, intense flank pain with nausea/vomiting and hematuria, plus possible groin radiation—is characteristic of urinary stones. The other symptoms listed don’t fit this pattern: a gradual dull ache suggests a non-stone cause; fever implies infection such as pyelonephritis or infected obstruction; cough is not related to stone pain.
