[Incidence of urocystographic abnormalities in urinary infection in the neonatal period].

Fifty-six children with ages between 3 hours and 45 days of life (median age 13.9 days), 39 of which were males and 17 females, have been studied. Urinary tract infection was diagnosed after two consecutive urine cultures with more than 100,000 colonies of the same pathogen obtained by sterile plastic bag. Whole urocystographic study was practised to every one of them, finding abnormalities in 17 of the patients (30.35%). Pathologic findings in 8 of them were considered important abnormalities (ureterohydronephrosis and/or vesicoureteral reflux grade IV) which makes 14.28% of the total. From their sample authors conclude that it is mandatory to practice whole urocystographic study to all children diagnosed of urinary tract infection in the neonatal period.
