[|Human|] My father has blood in his urine so he went for an ultrasound and they found a mass on the lower left pole of his kidney. i dont recall the size of the mass but it was fairly large. He also had a urinalysis done and the Cytology Daignosis came back with Atypical urothelial cells present and RBCs present. Is is possible that this is a large kidney stone cuasing the issue rather than cancer?
[|AI|]  Hello and welcome to Chat Doctor. As a Urologist, i can understand your anxiety. You should've written his age. A stone is very easy to diagnose on any scan and will be reported also. A mass or tumor, needs a ACTIVE, for further evaluation, ands very accurate. Typically, the person has blood in urine, whichs sent for a cytology test. Atypical cells further increase the chance, of the tumor being a cancer. A CT guided needle biopsy, is done in most centers, to confirm the diagnosis. You may send the reports to me, as a direct question, to clear all your doubt. Chat Doctor.  Manga.
