A 7-year-old girl was admitted with symptoms of abdominal pain, frequency, dysuria, and urgency. A urine culture showed a colony count of 100,000 Escherichia coli per high-power field. She had a history of three urinary tract infections within the previous two-year period. Each time, she had pyuria and was treated with sulfisoxazole for two weeks. Follow-up urinalyses had normal results.

On physical examination, she was found to be a well-developed, well-nourished, normal-appearing 7-year-old girl.
