Technetium Tc 99m dimercaptosuccinic acid renal scintigraphy in diagnosis of urinary tract infections in children with negative culture.

Introduction: The aim of this study was to evaluate the accuracy of Technetium Tc 99m dimercaptosuccinic acid (99mTc-DMSA) renal scintigraphy in the diagnosis of urinary tract infection (UTI) in children with suspected infection but with a negative urine culture.

Materials And Methods: The records of all children with suspected or definite diagnosis of UTI presented during a 2-year period were reviewed in this study. Abnormal findings on renal scintigraphy, voiding cystourethrography (VCUG), and ultrasonography were evaluated and compared between the patients with the definite diagnosis of UTI and those with suspected UTI and negative urine cultures.
