Avoidance of voiding cystourethrography in infants younger than 3 months with<i>Escherichia coli</i>urinary tract infection and normal renal ultrasound

Abstract

In infants aged 0-3 months with a first febrile UTI, the presence of <i>E. coli</i> and normal renal US findings allow to safely avoid VCUG. Performing VCUG only in infants with UTI secondary to non-<i>E. coli</i> bacteria and/or abnormal US would save many unnecessary invasive procedures, limit radiation exposure, with a very low risk (<1%) of missing a high-grade VUR.
