The presence of oligohydramnios and additional renal or extrarenal anomalies suggests significant pathology. o All patients with ANH should undergo postnatal ultrasonography The intensity of subsequent evaluation depends on anteroposterior diameter APD of the renal pelvis andor Society for Fetal Urology SFU grading. Patients with postnatal APD exceeding 10 mm andor SFU grade 3-4 should be screened for upper or lower urinary tract obstruction and vesicoureteric reflux. Surgery is considered in patients with increasing renal pelvic APD andor an obstructed renogram with differential renal function 35-40 or its subsequent decline.
