Enlarged Kidney

Hi. I am emily and I just had a cystoscopy yesterday because of an obstruction in my right kidney. They put in a stent. This is all very odd to me because this was an incidental find, as they were looking for something else. Apparently I have three kidney stones (largest 1cm) in my kidney, but they are not what is causing the obstruction. He wasn't able to tell what was causing the obstruction because things were so enlarged he couldn't tell. So now I have to keep the stent for about three weeks, have a renal scan and then meet with the doctor to discusss options. Anybody ever have a similar experience? What should I expect next? I don't know if I am in for a major health problem or a bump in the road. Feeling very uneasy about the whole thing. Any shared experiences are appreciated.
