2 years female has been successfully treated for urinary tract infection. Next step in management is :
Do nothing
Ultrasound
Ultrasound + DMSA scan
6 monthly culture sensitivity
The primary concerns following the diagnosis of UTI are :


The presence of an underlying urological anomaly (obstruction or VUR).
Involvement of kidney (Pyelonephritis).


Recommended radiological evaluation includes a combination of -


USG.
Micturating cystourethrogram (MCU).
Radionuclide scan (DMSA).

 

Indications of detailed radiological investigations are -


Child below 3 yr old with first UTI.
Symptoms of pyelonephritis.
Recurrent UTI.
Abnormal voiding (dribbling, straining, abnormal urinary stream).
Persistently distended bladder.
Family history of UTI or hypertension

Coming back to question
As this child is below 3 year (2 yrs) with first UTI, detailed radiological investigations are recommonded.
