Urinary tract infections in newborns

Abstract

The retrospective analysis had been performed on 3480 newborns weighted more than 1001 g, over the period of thirty one months. There was evaluated the frequency (1.25%), and clinical manifestation of the disease in newborns. Male and full term infants suffered from the disease more frequently then other evaluated infants. About half of cases were asymptomatic in the beginning of disease, and in the majority part of them, course of illness were non-characteristic. There was observed generalised oedema and swellings, irritability, intensive jaundice, dehydration, fever and poor peripheral perfusion. Laboratory findings manifested: anemia, hypoglycemia, higher WBC, metabolic acidosis, and especially hyperbilirubinemia, and in urine: pyuria and proteinuria mainly. In most cases of the disease urea and creatinine level in the serum were normal. The most dominant pathogenic agent was E. coli (above 72%).
