My first concern is if you have consulted a urologist? Your child is most likely to be suffering from vesicoureteric reflux where urine from bladder reflux back into the kidney
. It can be confirmed by doing a x-ray examination called voiding cystourethrogram
. Her right kidney is small and it needs to be evaluated for function. I don't know if she is taking antibiotics regularly but since she is already 5 yes old and still having infection she will need surgery for correction of abnormality.
