What is the risk of Down syndrome with fetal pyelectasis?

Although Down syndrome can occur in any pregnancy, the chance for Down syndrome increases with the mother’s age. When pyelectasis is seen on ultrasound, the risk for Down syndrome is approximately one and one-half (1.5) times a woman’s age-related risk.

What is mild fetal pyelectasis?

Fetal pyelectasis was classified as mild if the anteroposterior renal pelvis diameter measured >5 mm-< or= 7 mm, moderate >7-< or = 10 mm and severe as >10 mm. Persistant fetal pyelectasis was defined as >7 mm in the third trimester. Results: During the study period fetal pyelectasis was identified in 74 women.

What are soft markers for Down syndrome?

These markers are nonspecific, often transient. The most commonly studied soft markers of aneuploidy include a thickened nuchal fold, long bones shortening, mild fetal pyelectasis, echogenic bowel, echogenic intracardiac focus, FMF angle > 90 degrees, pathologic velocity of Ductus venosus and choroid plexus cyst.

How often does pyelectasis occur in third trimester?

Persistent fetal pyelectasis is defined as >7 mm in the third trimester (1). Incidence: Abnormalities of the urinary tract can be found in up to 5% of newborns.

When to take an ultrasound for fetal pyelectasis?

Radiographic features. Ultrasound. Fetal pyelectasis is assessed as an AP measurement of the renal pelves on an axial plane ultrasound image. It is considered present if measurements are above the levels stated below: >4-4.5 mm at 18-20 weeks (i.e. the routine 2 nd trimester) >5 mm at ~20-29 weeks. >6 mm at 32 weeks.
