Use of an Allograft Kidney with a Non-Obstructive Congenital Megaureter

Non-obstructive congenital megaureter (CM) is uncommon and its exact etiology is unknown. A renal allograft with CM was obtained from a live donor and transplanted, with continuing excellent function of the graft in the recipient. Follow-up studies reveal no evidence of progressive dilatation of the pelvi-calyceal system, urinary stasis, or infection. If the area of pathology is excluded in the procured segment of ureter, kidneys with CM can be transplanted, with a subsequently favorable outcome.
