There has already been a comprehensive evaluation performed.
One consideration would be vesicoureteral reflux. This is retrograde passage of urine from the bladder to the upper GU tract, and can lead to UTIs in children.
The test that would diagnose this would be a voiding cystourethrogram (VCUG) or a radionuclide cystogram (RNC). Most children diagnosed with a UTI should have a VCUG considered.
These options can be discussed with your urologist.
Followup with your personal physician is essential.
