UTI

Can a urologist find out if you have a kidney infection? ive been having utis off and on for 4 months. And im having terrible back pain and i went to the ER and they want me to see a urologist. please help

thank you

Definitely.  The urinary tract is what they deal with.

Yes.  Go and see the urologist.  

Okay i did today he wants to do a CT with the dye and he wants to find out why i still have infection thats not going away

Sounds as if the doctor thinks you have a kidney and/or bladder stone(s).  If you do, that could create an ongoing infection.
