Varda BK, et al. - Researchers ascertained the incidence of urinary tract infection (UTI), and the relationship between continuous antibiotic prophylaxis (CAP) use and UTI during the interval between birth and the first postnatal renal ultrasound (RUS) in infants with antenatal urinary tract dilation (AUTD). Findings suggested a low incidence of UTI prior to initial neonatal imaging in newborns with AUTD. Authors did not note the association of use of CAP with UTI incidence after adjusting for UTD severity. In most patients, a limited benefit of the routine use of CAP in newborns with AUTD before initial imaging was seen.
