I have a son who is twelve years old.  He started having back pain. Incidentally upon making an MRI for the back, we found that his left kidney was slightly enlarged. We have done an ultrasound and also found that both the left kidney and a part of the pelvis are enlarged. He is not complaining of any pain currently and there has been no sign of blood in his urine. What is your advice?
Hi and welcome to Chat Doctor. As a Urologist, I can understand your anxiety. Enlargement of a kidney may occur by birth. The MRI scan will confirm this finding. The difference between the two kidneys size, shouldnt exceed 2 CMS. As he's not having any symptoms, you don't need to worry about it. If you've any other doubts, send it as a direct question in my name. Chat Doctor.  Manga.
