Background and purpose : Regarding the importance of diagnosis and proper time of treatment in patients with urinary tract infection (UTI) and vesicoureteral reflux as risk factors for scar, this study was performed to detect the probability of scars appearance in children. Materials and methods : This study was performed on 42 children with urinary tract infection and vesicoureteral reflex (detected by VCUG), referred to pediatric nephrology units (clinic and ward) of Amirkola children hospital and evaluation of scar was done by DMSA at least 4-6 month after the last UTI. Results : of 42 patients, 29 (69%) were female and 13 (31%) were male. Among 84 checked renal units, 64 had reflux and 20 had no reflux with 62.5% and 15% of the cases with scars. In males 21 units and in females 43 units had reflux. 2.8 of renal units with reflex grade I, 13.24 with grade II, 17.23 with grade III, both renal units with grade IV and 6.7 with gradeV had scar (P=0.001). Conclusion : The results of this study showed that males and age group of 1 month to 2 years have higher risk for VUR and scar. In spite no correlation was found between age of children and scar. However, prompt evaluation and proper time of treatment are very important.
