Crossed renal ectopia.
Crossed renal ectopia is an unusual congenital anomaly, probably produced by abnormal development of the ureteral bud. The deformity itself produces no symptoms and the clinical presentation generally is for obstruction and infection. In our series the adult patients presented most commonly with urinary tract infections, while the pediatric patients presented most often with multiple congenital anomalies, especially of the skeletal system.
