This national study is a feasibility study. It wants to validate all stages of the endovascular preparation of the iliac axis up to the kidney transplant for patients in whom the installation of a tailor-made endoprosthesis was necessary beforehand. These patients are currently at a therapeutic impasse. This strategy of renal transplantation on an iliac artery endoprosthesis could ultimately give them access to the transplant with an improvement in quality of life and survival, for lower costs of care for the hospital and safety. less social than treatment by hemodialysis
