Furthermore, recent data have shown that in children <3 months of age with first febrile UTI, the presence of E coli in urine, and normal renal and bladder US, VCUG can be safely avoided [18]. MRI Abdomen and Pelvis With IV Contrast There is no relevant literature to support the use of MRI abdomen and pelvis with IV contrast in the evaluation of a child AMAB <2 months of age for the initial imaging of a first febrile UTI. MRI Abdomen and Pelvis Without IV Contrast There is no relevant literature to support the use of MRI abdomen and pelvis without IV contrast in the evaluation of a child AMAB <2 months of age for the initial imaging of a first febrile UTI. MRU Without and With IV Contrast There is no relevant literature to support the use of MRU in the evaluation of a child AMAB <2 months of age for the initial imaging of a first febrile UTI. Nuclear Medicine Cystography There is no relevant literature to support the use of nuclear medicine cystography in the evaluation of a child AMAB <2 months of age for the initial imaging of a first febrile UTI. There is good correlation between nuclear medicine cystography and VCUG for the detection of reflux [19]. The nuclear cystogram does not allow for urethral assessment in a infant AMAB [20]. US Kidneys and Bladder In a child AMAB <2 months of age, there is increased incidence of sepsis and renal anomalies associated with UTIs and increased rate of hospitalization. Therefore, the potential benefit of imaging in children <2 months of age is greater than in older children. However, there is less convincing evidence for the benefit of imaging based on outcome [8-11,21]. Hydronephrosis is the most frequent abnormality, found in 45% of neonates with UTI [9]. Postnatal US prior to 2 months of age is typically performed even if the prenatal US was normal.
