Crossed renal ectopia in children

Five cases of crossed ectopic kidneys are presented, four in males and one in female, four fused and one unfused. All were on the right side; in four cases the kidneys were positioned inferiorly and in one superiorly. Urological malformations and accompanying anomalies were observed in most of our cases. Vesicoureteral reflux was demonstrated in the three children in whom cystography was performed. In the presence of anorectal malformations and vertebral anomalies or on diagnosis of crossed ectopic kidneys, early and thourough urological investigation is indicated.
