Out 15 cases, 8 fetuses (53%) mild urinary tract (UTD A1) and 7 (47%) UTD A2-3. almost 75 % hydronephrosis resolved postnatally, while in 2/8 (25%) it persistent till 1 year follow up. 60% (4/7) A2-3 vesicoureteric reflux after birth. other – ectopic kidney (n 3), cysts 2, out which resolved, another hypoplasia occurred), double moiety subsequently), horseshoe 1), 1) unilateral agenesis(n 1). scan dilatation, got one-third However, two-third not mid-trimester structural instead developed/ by re- evaluation scans.
