Anyone have experience with Fetal Hydronephrosis?

Ellie 💙

Found out at anatomy scan with perinatologist that my son has mild fetal hydronephrosis. I go back at 32 weeks for another detailed scan to see if it’s corrected itself or worsened. They didn’t really tell me much about it, just that it can range from correcting itself by birth to correcting by 1st Birthday to possibly having surgery at birth depending on severity. Has anyone else’s little one had this?
