Risk factors for vesicoureteral reflux include:

  • Race. White children appear to have a higher risk of vesicoureteral reflux.
  • Sex. Generally, girls have about double the risk of having this condition as boys do. The exception is for vesicoureteral reflux that's present at birth, which is more common in boys.
  • Age. Infants and children up to age 1 are more likely to have vesicoureteral reflux than older children are.
  • Family history. Primary vesicoureteral reflux tends to run in families. Children whose parents had the condition are at higher risk of developing it.

    Siblings of children who have the condition also are at higher risk, so your doctor may recommend screening for the siblings of a child with primary vesicoureteral reflux.
