33 weeks 5 days and scan shows dilated kidney

Chontae
Extremely worried now about my daughter as she has one dilated kidney, the sonographer said don't worry to much this can usually be sorted after baby is born, but then silly me googled it an it says it can be a downs symptom... Even tho I had the 13 weeks scan n all was fine, I'm still so worried... Has this happened to anyone an all be okay once born, just perhaps issues with kidney no actual downs? And what did they do to help their kidney!?
