Abstract

Objective:Our aim was to determine the incidence of anatomical abnormalities after a urinary tract infection (UTI) in infants 2 months of age hospitalized in the neonatal intensive care unit (NICU).Study Design:This was a retrospective, single-center cohort study of infants 2 months of age in the NICU with a UTI and documented renal imaging.Result:We identified 141 infants with UTIs. The mean gestational age and birth weight were 28 weeks and 1254 g, respectively. The most commonly identified pathogen was coagulase-negative Staphylococcus (28%, 44 of 156). A major abnormality was found on at least one imaging study for 4% (5 of 118) of infants. Major abnormalities were noted on 4% (5 of 114) of renal ultrasounds and 2% (2 of 82) of voiding cystourethrography examinations.Conclusion:Among infants in the NICU 2 months of age at the time of a UTI, the prevalence of major anatomical abnormalities is 5%.
