Crossed solitary renal ectopia.

A boy being followed for cardiovascular anomalies was found at age fourteen to have a solitary right kidney which drained to the left side of the bladder. We have reviewed the reports of 33 patients with solitary crossed renal ectopia which describe many associated congenital anomalies especially in the genitourinary and skeletal systems. We found no description of associated cardiac anomalies. We review the literature on solitary crossed renal ectopia and describe an additional case.
