Doctor: The presence of white blood cells in the urine indicate a urinary tract infection by bacteria. The most appropriate next step is to culture the urine and take appropriate antibiotics. Also since you have a previous history of renal reflux disease, an ultrasound or IVP may be required to rule out pyelonephritis.
