A kidney stone obstructing the ureter typically presents with which pain pattern?

Explanation:
When a stone blocks the ureter, the ureter and surrounding renal tissue respond with intense, waves-like contractions and distension. This produces a sudden, severe, unilateral pain known as renal colic. The pain usually starts in the flank or the costovertebral angle and commonly radiates down to the groin, testicle in men, or labia in women as the stone moves. The patient is often restless and diaphoretic and may have nausea or vomiting. Hematuria can also be present. Other options don’t fit this pattern because a persistent cough relates to the chest/airway, hearing loss to the ear, and jaundice to liver/biliary issues—none of which produce the characteristic sudden, unilateral flank pain that radiates to the groin seen with ureteral obstruction.
