Dialated kidney

Doctors thought this was the problem with my baby's kidney at 18 weeks.. Turned out to be a small cyst on her right kidney. Just went today and everything was all back to normal! Doctors told me it was nothing to worry about. They just monitored it and usually it will fix itself! Your baby will be perfect no matter what! Don't worry mommy ? 

My little girl has had kidney issues since 20 weeks. So far they've said that if it doesn't fix itself it'll just be monitored after birth and that it's nothing to lose sleep over. Her issues are more with extra fluid in her kidneys though, I think they may have said something about a dialated kidney at one point due to my hormones (which of course made me feel like a bad guy) but so far they're still just monitoring and trying to keep me calm. ​ 

Hello Ladies, ​Thank you for your replies. and the good news is that the baby's kidney is came back to normal size, its still dialated but its in normal range, so there is no need of ultrasound the baby after delivery. Now I'm stress free?. 

No suggestions but I didn't want to look and run.
