Which of the following is a common symptom of renal calculi?

The key symptom being tested is the hallmark presentation of a renal stone: sudden, intense, unilateral flank pain from the stone obstructing the ureter. This pain, often described as sharp or stabbing, commonly starts in the side or back and may radiate toward the groin as the stone moves. The pain is typically episodic and colicky due to intermittent blockage and ureteral spasm, which makes it the most characteristic sign of renal calculi. Other signs like cloudy or foul-smelling urine can occur if infection is present, fever and chills suggest infection, and nausea/vomiting can accompany the pain. However, these are not as specific to stones as the abrupt, severe flank pain driving the diagnosis.
