Relationship between hair/eye color and primary vesicoureteral reflux in children

The relationship between hair/eye color and primary vesicoureteral reflux was analyzed in more than 900 children. Children with blonde hair/blue eyes did not show an increased prevalence of reflux nor did any other hair/eye combination. With the possible exception of rufous coloring, the color of the hair and eyes are poor predictors of the competence of the ureteral orifice.
