Vesicoureteral reflux is a common condition in children. It may cause and maintain urinary tract infection, evaentually leading to progressive renal damage and end-stage renal disease. Wilms' tumor is the most common primary malignant renal tumor of childhood. There is no literature that vesicoureteral reflux combined with Wilms' tumor. We report rare case of bilateral vesicoureteral reflux combined with left Wilms' tumor.
