Ureteral replacement with appendix in pediatric renal transplantation.

Ureteral necrosis is an uncommon complication following RT which can adversely affect outcome. Even though authors agree that the native ureter ought to be preserved, there are cases in which graft function can only be salvaged by ureteral substitution.
