Acute pyelonephritis (APN) is a common febrile illness of children.
Improper treatment of APN may lead to an irreversible damage of renal parenchyma, a decrease of GFR, and eventually hypertension and chronic renal insufficiency.
Early diagnosis and rapid effective antibacterial therapy for APN are vital for the prevention of renal scarring or chronic pyelonephritis.
Renal cortical scintigraphy (DMSA scan) is a highly sensitive and specific method to detect renal cortical abnormalities and be recommended the gold standard for the diagnosis of APN and be done routinely in children with UTI.
