Kidney Diseases

What causes a kidney to shrink?



My daughter has been told one kidney is smaller and there is a blockage which is not a stone. She is 24 and has just had her second baby.


Many possibilities for a small kidney. It could be congenital. If she has high BP it could be from a blockage in the renal artery. If she had many urine infections as a child it could be related to that. Knowing what her blood and urine tests show would help in sorting this out. It needs to be evaluated further so as to decide the cause. You stated there as "blockage" but I cannot know if this was in the ureter or the artery. Both types of blockage can cause small kidneys. Please follow through on this because some blockages need to be treated.
