MSFinals-6612
A 26-year-old female patient arrives at the emergency department complaining of left-sided flank pain that has been ongoing for two hours. The pain radiates down towards her groin and is constant, unaffected by changes in position. She reports feeling nauseous and has vomited once. The patient has no significant medical history and is not taking any regular medications.
Upon examination, the patient is tender over the left costovertebral angle and shows signs of guarding, but no rebound tenderness. Her vital signs are heart rate 112/min, blood pressure 120/76 mmHg, temperature 38.1ºC, respiratory rate 14/min, and saturations 97%. An ultrasound scan of the kidneys reveals dilation of the renal pelvis on the left, while a CT scan of the kidneys, ureters, and bladder shows a 4 mm stone in the left ureter. What is the most appropriate course of action?
