What could be the cause of an enlarged kidney? - enlarged kidney

Basically, I had some back pain on both sides, but especially on the right side. I went to go to my doctor and I was referring to an ultrasound. During that told me that my right kidney appeared to be enlarged and can not drain properly (or nearly all). I did not really say anything, just woulkd that the results are forwarded my doctor in 7-10 days. I want to know what is wrong! Suggestions?
