What do i do with a kindney enlargement?

What caused the: if an obstruction, you need to see a urologist. for any other reason see your nephrologist

Depends on underlyin: What are the issues for the underlying health reasons to cause the enlarged kidney. How is your kidney function? It may be good for the kidney to been enlarged if the other kidney is not functioning. The body will enlarge one of the kidneys to make up for a poorly function of the other kidney. Your physician will evaluate these options to evaluate the reason for the enlarged kidney

Various possibiliies: mostly not so good. Without an actual examination, I cannot give specific medical advice on your particular health mostly it is due to a blockage out from the kidney, and the kidney blows up like a balloon. It is treated by removing the blockage. Polycystic kidney sometimes a kidney is just big without abnormality but this isn't so common.
