title: Crossed, fused renal ectopia with severe hydronephrosis: angiographic diagnosis.
abstract: The authors describe two children with crossed, fused renal ectopia in whom severely damaged hydronephrotic ectopic kidneys were not shown by intravenous urography. Aortography confirmed the diagnosis in both patients. Aortography is of great value if a diseased ectopic kidney must be resected; demonstration of the vascular supply to both kidneys enables the surgeon to preserve all of the normal renal tissue.
