- one episode of UTI with acute pyelonephritis/upper urinary tract infection plus one or more episode of UTI with cystitis/lower urinary tract infection, or

** ultrasound in toilet-trained children should be performed with a full bladder with an estimate of bladder volume before and after micturition
*** in a child with a non-E. coli-UTI, responding well to antibiotics and with no other features of atypical infection, the ultrasound can be requested on a non-urgent basis to take place within 6 weeks
