Hi, Welcome to HCM, I am Dr. Das
First of what was your symptoms ? why did you go for urine and CT test?
Normally, epithelial cells
and bacteria may be found in urine. But, to stamp a infection the amount of bacteria is important which you did not mentioned.
Coming to the CT finding it indicates you have a nodular mass in your kidney
which is probably benign.
I wonder why the Doctor who were present during scan adviced for CT guided FNAC which would definitely confirm the diagnosis and decreases anxiety
So, go for CT guided FNAC.
