Which sign differentiates kidney stones from other abdominal pain?

• A. Chronic cough
• B. Weight loss
• C. Cloudy urine with no pain
• D. Severe acute flank or groin pain with hematuria

Answer: (D)

Kidney stones typically cause sudden, severe, unilateral flank pain that often radiates to the groin. This intense, colicky pain, paired with blood in the urine, is the clue that sets stone pain apart from other abdominal problems. The stone irritates and sometimes scratches the lining of the urinary tract as it moves, which explains the hematuria. Cloudy urine can suggest a urinary tract infection, but that finding doesn’t usually come with the sudden, severe flank or groin pain seen with stones. Chronic cough and weight loss aren’t characteristic signs of kidney stones and don’t explain the sharp, localized pain with hematuria. So the sign that differentiates kidney stones from other abdominal pain is severe acute flank or groin pain with blood in the urine.
