Genitourinary Tract

Abstract

Congenital and acquired pathologies of the urinary tract are among the most common pediatric diseases. Renal radionuclide studies are a cornerstone of the evaluation of these pediatric abnormalities, being simple and safe tests, and providing unique clinical information. Dynamic renography is commonly performed in conjunction with furosemide pharmacological intervention, assesses the relative kidney function and the drainage from kidneys and ureter, Renal cortical scintigraphy evaluates congenital and acquired abnormalities in the renal parenchyma. Direct and indirect radionuclide cystography are used to evaluate vesicoureteral reflux (VUR). Non-imaging radionuclide GFR measurements using a single tracer administration are more precise than biochemical tests. The latter requires an experienced team and rigorous methodology.
