RESUMO
Anomalies of the vesicoureteric junction are important, particularly obstruction and reflux, as they may predispose to urinary tract infection. Over a 5-year period, 52 babies were referred with dilatation of the urinary tract detected antenatally or/and postnatally by ultrasound. Sixteen had an anomaly of the vesicoureteric junction: 9 had vesicoureteric reflux, 3 had ureteroceles, 1 had urethral stenosis with secondary reflux and 3 had stenosis of the vesicoureteric junction. Ten patients underwent 14 surgical procedures. The mean time to reconstructive surgery was 9.3 months. Ultrasonography showed regression of the dilatation in all patients who underwent surgery. Seven patients with minor dilatation are still under observation. In only 1 case was there loss of renal parenchyma. With conservative medical treatment the patients are 1 year old before reconstructive surgery is undertaken; with reflux, however, progression may indicate earlier surgery.
