I Have A Two Year Old Daughter And She Has

I have a two year old daughter and she has had 2 recent UTI's. As a result we've had some testing done and she has reflux 4. Today's renal ultrasound notes the following: mild right renal pelvocaliectasis with mild right urothelial thickening.

We see a urologist in two weeks, but I am trying to research the report notes and not finding much. Any info would be appreciated. I understand you cant give specifics on her case, but in general what does this usually mean and what type of outcome is standard in this situation?

Thank you much,
A concerned mom
