DURAN ALVAREZ, Sandalio et al. Postnatal diagnoses of abnormalities of the urinary tract detected by maternofetal ultrasound. Rev Cubana Pediatr [online]. 2004, vol.76, n.4. ISSN 0034-7531.

A retrospective analysis is made of the postnatal diagnoses in children studied due to the detection of some abnormality or alteration of the urinary tract by maternofetal ultrasound. 120 children with these characteristics that were born between January 1 st ,1996 and December 31 st , 2003 , were referred to the Nephrology outpatient department of “William Soler” Pediatric Teaching Hospital. Of them, 82 were males (68 %). The analysis was made in 109. 11 left the follow-up before concluding the study. The diagnoses established were: 57 non obstructive hydronephrosis (52.3 %), 17obstructive hydronephrosis (15.6 %), 16 vesicoureteral reflux (14.7 %), 7 multicystic renal dysplasia (6.4 %), 6 double excretory system (associated or not with other abnormalities) (5.5 %), 2 nonobstructive megaureter (1.9 %) and left renal agenesia, ureterocele in a simple system, megakaliosis and dominant autosomic policystic renal disease, one of each. The most frequent prenatal alteration was nonobstructive hydronephrosis, but due to the importance of some of the other diagnoses, all the alterations of the urinary tract detected during pregnancy should be studied and carefully followed -up in the neonatal period.
