Which symptom is most characteristic of a kidney stone?

• A. Anxiety, restlessness
• B. Nausea and vomiting
• C. Hematuria
• D. Tremendous pain in the flank radiating to the pubic symphysis

Answer: (D)

Kidney stones typically cause ureteral colic—sudden, severe flank pain that is often described as cramping or tearing and that moving stones makes worse or better in waves. This intense pain usually starts in one flank and radiates toward the groin or pubic region as the stone travels through the ureter. That radiating, high-intensity pain is the most characteristic feature because it directly reflects the obstruction and spasms of the ureter. Nausea and vomiting can occur with the pain, and blood in the urine may be present, but these signs are less specific. Anxiety or restlessness can accompany severe pain, but they don’t define the condition. So the hallmark symptom to recognize is the tremendous flank pain radiating to the pubic area.
