[The frequency of urinary tract infections in hospitalized infants].

The authors present the frequency of urinary tract infections in hospitalised infants. A retrospective study of infants hospitalized during a five year period, from 1979-1983 was made. The average frequency for the mentioned period was 12%, all of which were bacterial infections. In 70.7% of patients we diagnosed cytopyelonephritis. Girls prevailed among the patients with urinary tract infections, even in the neonatal period. Vesicoureteric reflux was confirmed in 36.5% children. The results of this study show that the symptoms of urinary tract infections in infancy are not specific. As the frequency of cytopyelonephritis and vesicoureteric reflux was high it emphasizes the significance of early diagnosis. In every febrile child, diagnosis of urinary tract infections should be suspected.
