Surgical complications of renal transplantation, rejection and infectious diseases are factors contributing to poor renal graft survival. Factors directly concerning the donor can be involved in graft failure: age, medical history, causes of donor brain death. Urologic or arterial anatomic variations are often the source of difficult surgical conditions during renal transplantation. Technical errors during graft procurement must be avoided such as excess of traction or coagulation. Failure in perfusion preservation. As few renal grafts are available, it is thus essential to obtain optimal conditions to avoid failure in cadaver donor graft linked to technical errors during organ procurement.
