Misshapen kidney

06/04/2010

Question:

During a recent CT scan for an unrelated problem it was discovered that my right kidney had a "bump" on it.

Recently I have developed twinges in my lower right back but only when I move.There is no pain as such. Could this be associated with my misshapen kidney? I`m a 71 year old male who suffers from osteoarthritis.

Answer:

No, the unusual shape of your right kidney is very, very unlikely to be causing the twinges you feel in your lower back.  Fetal kidneys have a different shape than adult ones and are more lumpy or "lobulated"-looking; they gradually smooth out with age, but sometimes a hump will persist.  Ask your doctor whether the lump had any kind of unusual appearance, suggesting that it might be a tumor; if so, further studies should be obtained, and if not, don't worry about it any more.  Please see the link to our article on "kidney pain" for a description of the sort of pain that can be blamed on the kidneys.
