Before registering a patient on the kidney transplant waiting list, the medical file should be carefully studied looking for factors that may complicate the transplantation. Knowledge of the patient's history and the clinical examination will guide the choice of complementary examinations. The objectives of pretransplantation explorations are : 1) preventing graft rejection ; 2) ensuring that arterial and venous anastomoses are possible ; 3) ensuring that urine can be drained ; 4) preventing post-transplantation infections ; 5) not performing a transplantation on a subject with cancer ; and 6) avoiding any post-transplantation cardiovascular events. The list of the necessary explorations for renal transplantation should be as simple as possible so that registration on the transplant waiting list is not delayed, while being as complete as possible to prevent any complications that may compromise the results. It should be individualized to each patient.
