Abstract：
:The excretion urogram-nephrotomogram is the most important imaging study in the diagnosis of renal parenchymal infection in children. If renal parenchymal infections are discovered before significant necrosis has occurred, vigorous treatment with appropriate parenteral antibiotics may result in resolution without the need for surgical drainage.
