Re: urologist or nephrologist?
The bottom line is that your kidney function is normal. That is great news. Many people have cysts. All kinds of cysts and there is no reason to remove them. Why would you want an invasive, dangerous procedure that will not benefit you at all?
There may be some pain due to either an infection or a small stone. The pain may be in both kidneys because it is referred. Referred pain is where you have pain in one area but it spreads because the nerves become sensitized.
A follow up in a few months sounds perfectly normal to me too. Quitting smoking will also do wonders for the way you feel. It is possible that some of the pain is also left over from the soda. Did you drink a lot of soda with caffeine? That is not good for you and can specifically irritate the bladder and the kidney. Give it a bit of time for your system to recover from the soda and see what the next test shows.
The bottom line is that if your bloodwork is normal for kidney function, then at this point you don't really have anything to worry about. Easy for me to say, I know, but keep in mind that the docs see a lot of this sort of stuff and if there was something to worry about, they would worry. Nobody gets referred to a nephrologist unless test shows some problem with kidney function, and you don't have that.
