Kidney retransplantation from HLA-incompatible living donors: A single-center study of 3rd/4th transplants.

Background: The demand for kidney retransplantation following graft failure is rising. Repeat transplantation is often associated with poorer outcomes due to both immunological and surgical challenges. The aim of this study was to compare surgical and functional outcomes of kidney retransplantation in recipients that had previously had at least two kidney transplants with a focus on those with antibody incompatibility.
