Unilateral vesicoureteric reflux: Low prevalence of contralateral renal damage

Objective: We assessed the risk for the occurrence of renal damage in children with vesicoureteric reflux (VUR). Study design: We reviewed the records of 187 consecutive children, aged 3.8 ± (SD) 2.8 years, with unilateral primary VUR diagnosed after urinary tract infection (UTI). Dimercaptosuccinic acid renal scintigraphy was performed 4 to 6 months after the last UTI. Three patterns of renal damage were identified: global reduction (GR) of renal radionuclide uptake (20% to 40% of relative uptake), focal defects (FD) in uptake, and shrunken (relative uptake
