I went for my anatomy scan today at 21 weeks.  All looked great except the doctor said my baby boy had enlarged kidneys measuring at 5cm.  She is sending me to do a second scan with better ultrasound equipment to make sure there isn't anything too concerning.  She didn't seem too worried as this apparently is somewhat common and didn't see any other health complications.  Has anyone else had this experience?  How was the outcome?  The doctor seemed pretty calm so I am trying stay calm as well.  But, I just want to know more about other people's experiences with this condition.
