My baby boy currently has pyelectasis. I'm 21 weeks, almost 22. We found out one of his kidneys is 4.8 mm and the normal size is 4mm and under. So it's barely dilated. My doctor scheduled me to go back and get another ultrasound at 32 weeks and I'm terrified. Everything else was perfectly normal except for his kidney. I guess I'm just looking for other people that have been through this or are going through this? Maybe a little comfort, idk. It's my first baby and to be honest, it's very very terrifying. They also said it is a very veryyyyy small marker for Down syndrome. But they look at other features in the face for that as well and all those ones were normal so they don't think he has it.
