What follow-up investigations are necessary for a child with a UTI and abnormal renal ultrasound findings?

Follow-up investigations for a child with a urinary tract infection and abnormal renal ultrasound findings include a dimercaptosuccinic acid (DMSA) scintigraphy scan 4 to 6 months after the acute infection to detect renal parenchymal defects ¹.

If the ultrasound shows dilatation or other abnormalities, consider a micturating cystourethrogram (MCUG) to assess for vesicoureteral reflux (VUR) ¹.

In cases where upper UTI is suspected or confirmed, power Doppler ultrasound or DMSA scan may be used to confirm or exclude acute upper UTI ¹.
