No.: Fetal pyelectasis refers to borderline prominence of the renal collecting system and is defined as >4 mm by 20 weeks; >7 mm between 20-30 weeks and >8 mm after 30 weeks. It is seen in 3% of all pregnancies associated with polyhydramnios and diabetes mellitus. It is a very weak marker of increased risk for fetal Down syndrome but never causes mortal risk. Neonatal follow-up is required!
