Hi nicole
i had a scan last week and have been told exactly the same thing. I am expecting a little boy and he has enlarged kidneys. I have to go back for another scan at 36 weeks and was told not to worry!! Impossible!
I have been searching internet for "enlarged kidneys" and thats how I came across your posting.
The guy that did my scan did say that it occurred in 3% of pregnancies (he'd only ever come across it happening in boys) and that its due to a valve not being matured properly yet - but hopefully by the time we are scanned again the valve will have matured and the problem will have rectified itself. Apparently it nearly always does rectify itself before the baby is born.
If it doesnt for some reason then they will scan baby once it is born and apparently it is then more susceptible to infections etc. But im not sure whether or not it is anything more serious than that, or what they do about it - he didnt go into that - didnt want to panic me I dont think! (too late for that!)
i have been reading up on everything about kidneys and in one book it did say something about if left untreated it could lead to kidney failure but to be honest I wasnt even sure I was reading up on the same thing as I do not know technical name for "enlarged kidney" and I was reading up about fluid on kidney - so dont panic yet.
When is your due date and when do you get your next scan?
I know exactly how you are feeling and you cant help but worry - I am thinking about it all of the time. I will continue my search for info and let you know if I find anything else out.
