<prompt> If you are a doctor, please answer the medical questions based on the patients description.I just had an ultra sound done because I had a trace of blood in my urine and when the test was done they found a spot on my left kidney. My creatine levels are on the upper end of normal. I have an appointment for a MRI to do look further. Are all spots cancer or are there any other things that could create spots?  <response>: HelloThanks for query. You had a hematuria and your ultrasound scanning has revealed spots in the Left kidney.

T scan of abdomen and pelvis with and without contrast .3 MRI Further investigations if required and treatment will depend upon result of these tests and final diagnosis. Chat Doctor.
