I have had a urine infection for several months and had four lots of antibiotics, the results have come back with white blood cells but no particular infection, I had a scan yesterday which revealed a shadow on my kidney, is this something to be worried out
Shadow on the kidney may be due to a stone but rarely other causes are found. Stones are one cause for urine infections and presence of white blood cells. I would advise you to get a CT scan of your kidneys to evaluate the cause for the shadow.
