20 wks anatomy scan...

Ile🎠
I just came back from my ob's office with the results of my 20wks scan and he told me my baby boy kidney is dilated that he will send me for a more detailed ultrasound that I don't need to worry and it's common in boys 9 out of 10 it goes away before birth but it's hard not to when they say something is abnormal with your baby any advice?
