Background: Urinary tract infection (UTI) is the third most common medical problem in the pediatric population, especially in infants. Vesicoureteral reflux (VUR) is common in children with UTI. Objective: The aim of this article is to assess the relationship between VUR-associated UTI and renal scar in children. Materials and Methods: A cross-sectional study was conducted among children who were admitted in the Pediatric Nephrology Department of BSMMU with UTI during the period of March 2013 to July 2014. A total of 30 UTI patients aged 1–5 years were included in the study. Children with neurogenic bladder or structural abnormality of urinary tract other than VUR were excluded from this study. History of the patients was taken and physical examination was done and recorded. Several investigations such as urinary routine and microscopic examination, culture and sensitivity with colony count, ultrasonogram of kidney, ureter, and bladder with post-void residual urine, micturating cystourethrogram, and dimercaptosuccinic acid (DMSA) renal scan were done. The collected data were analyzed by using SPSS version 12. Results: Mean age of the patients was 2.50 ± 1.18 years within the range of 1–5 years. Boys (80.0%) were predominant than girls (20.0%). Among the right kidneys 10 (33.3%) and among the left kidneys 11 (36.7%) had renal scar. There was a significant relation between increased VUR grading and increased number of renal scars on right and left kidneys (P = 0.013 and P = 0.020, respectively). There was no significant relation between increased number of UTI episodes and increased number of renal scars on right and left kidneys (P = 0.057 and P = 0.951, respectively). There was a positive correlation between VUR grade and renal scar [r = + 0.741 (P < 0.001)]. There was a positive correlation between VUR grade and renal scar [r = + 0.917 (P < 0.001)]. Conclusion: It can be concluded that severity of VUR had a significant correlation with renal scarring on DMSA scintigraphy.
