Congenital unilateral renal agenesis is a rare congenital anomaly. Furthermore, renal agenesis associated with neuroblastoma and cryptorchism is more rare in incidence. Recently we experieced a case of Rt. renal agenesis combined with cryptorchism and neuroblastoma. We diagnosed it with IVP and selective renal angiography and confirmed it with explolaparotomy and biopsy. We reviewed the literatures on renal agenesis, cryptorchism and neuroblastoma, and discussed possible embryological relationships between them and other combined congenital anomalies.
