*For a child aged 1–4 years with a recurrent UTI and a previously normal MCUG, no investigations are needed. If no prior MCUG had been done, the options include having one then, or managing the child as if they were known to have VUR, and undertaking a MAG3 indirect cystogram from the age of about 3.5 years.
DMSA, dimercaptosuccinic acid; MCUG, micturating cystourethrogram; RCP, Royal College of Physicians; UTI, urinary tract infection; VUR, vesicoureteric reflux.
