title: [Fetal hydronephrosis: postnatal management and follow up].
abstract: OBJECTIVE
  Fetal hydronephrosis is being detected with increasing frequency and probably this observation will increase as the quality of ultrasound equipment improves. This study evaluated etiology and postnatal clinical outcomes of prenatally detected hydronephrosis.
  
  
  METHODS
  In a period of 13 years 148 infants were referred with fetal hydronephrosis. The initial evaluation, after prophylaxis, included ultrasound and voiding cystography. Sequential evaluation was determined by initial findings.
  
  
  RESULTS
  Postnatal predominant diagnosis were pelviureteric junction obstruction (24%) and hydronephrosis without obstruction (18%). Follow up median was 38.7 months. Renal function deteriorated in 13 (8.8%) children and 11 (7.4%) died during follow up. Bad prognosis was associated with urethral obstruction.
  
  
  CONCLUSIONS
  Fetal hydronephrosis is a clue of urinary tract anomalies. Urinary tract infections and delay in postnatal diagnosis must be prevented in children with this uropathy.
