A 3-year-old, previously healthy girl presents to the emergency department (ED) with fever, increasing abdominal distension, abdominal pain, decreased oral intake, and dysuria. Three weeks ago, she had dysuria and fever (100°F [37.8°C]) and was evaluated by her primary care physician and treated with cefdinir for 7 days for cystitis. She was then taken to the ED 5 days later with increasing abdominal pain and low-grade fever. At the ED, results of her urine analysis (UA) were negative, but she was started on trimethoprim-sulfamethoxazole. Since her symptoms worsened, she was again brought to the ED.
