Methods for increasing the nephron mass of a mammalian recipient are disclosed. A metanephros from an allogenic or xenogeneic mammalian donor is implanted next to a recipient's omentum or under the renal capsule of the recipient's kidney. The metanephros becomes vascularized by the recipient's blood vessels, forming a chimeric kidney that produces urine and develops a ureter that facilitates externalization of the urine. A ureter to ureter anastomosis can be subsequently performed to provide fluid communication between the chimeric kidney ureter and a ureter of the recipient.
