Urologic implications of the VATER association.

Among 23 children with the VATER association 21 had significant genitourinary involvement. The extent of these genitourinary anomalies is not generally appreciated. The principal renal anomalies were renal agenesis (7 cases), ureteropelvic junction obstruction (5 cases), crossed fused ectopia (5 cases) and severe reflux (9 cases). Since corrective urologic surgery is commonly beneficial for children with the VATER association, an early and appropriate urologic evaluation is indicated.
