Has anyone had any experience with fetal pyelectasis (basically fluid in the kidney)? A routine ultrasound last week at 37 weeks showed some freestanding fluid in the right kidney and a follow up ultrasound today confirmed it. The fluid pocket is measuring 9mm, which is apparently higher than normal but not too terrible. Sounds like we will need to follow up with a pediatric urologist after birth, but curious if anyone else has any experience?
