Consult a urologist: This child may have a number of problems, the most likely being vesicoureteral reflux or upj obstruction. She may need further studies, including a test called VCUG or a nuclear renal scan. If possible, consult with a pediatric urology subspecialist. She may need to be on antibiotics indefinitely until the problem can be diagnosed definitively.
