title: [Peculiarities of urinary infection in 145 infants younger than 3 months of age].
abstract: Authors have analized retrospectively 145 children with urinary tract infection (UTI) within the first 120 days of life. 67% were males, 45% of patients presented an acute onset with fever and septic appearance and 55 with a chronic illness with digestive symptoms and malnutrition (95%). Breast feeding could be a protective factor against UTI. In 66% of those less than one month old, existed perinatal infectious risk factors. This fact and the presence of septic signs and positive blood cultures (71%), give rise to the possibility that the hematogenous route be the principal infectious via in this age group. The high incidence of parenchymatous participation (75%) have no relation with the presence of obstruction. At onset 29 showed no anomalies on cysto-urography, 48% vesicoureteral reflux of various degrees and 23% obstructive anomalies. The mortality rate was 1,3% due to septic shock.
