Prenatal Diagnosis of Fetal Urinary Tract Abnormalities

With the introduction of Real-Time Ultrasound and the improved resolution of its gray scale capabilities, certain fetal urinary tract anomalies can be diagnosed reliably by experienced sonographers. Ultrasound scanning at 18–20 weeks of gestation is indicated in any patient who has already delivered a child with a birth defect, or has a strong family history of congenital anomalies. When the disease is bilateral or is associated with outlet obstruction, oligohydramnios occurs which could be the first clue to the presence of fetal G.U. anomalies. Oligohydramnios is often suspected first by the clinician and can be documented reliably by ultrasound. When present in the second trimester without premature rupture of membranes, the outcome most often is poor (1).
