Is a repeat Micturating Cysto-Urethrogram (MCU) and a DMSA Scan (Dimercaptosuccinic Acid) required in a 7 yr old girl, in which UTI Test gave culture positive results? She has been treated as per the culture-sensitivity report and is symptom-free now. The child had a Grade 2 Vesicoureteral Reflux (VUR) which spontaneously resolved 3 yrs back.

Last DMSA scan done at that time was ok. Please suggest management.
