The smaller kideny may have something wrong with it or it may be fine, just small, but you, and the doctors, aren't going to know what's what until the testing is completed. Even if there is a problem with the smaller kidney, you can live with one kideny your entire life and never notice any difference. Both of my son's kidneys are too small, but one is much smaller than the other, plus it is deformed, misshapen and has minimal function. His kidney function tests always look good, so the docs aren't worried about it, as it is obvious that his bigger kidney is handling his body's needs fine. It's okay to be concerned, but I wouldn't worry yourself sick unless/until you know you have something to worry about.
