[Ureteral revascularization in kidney transplantation. Report of a case]

We present uretero-pyeloplasty as a new surgical approach to stricture of the pyelo-ureteric junction in the transplant recipient. The foregoing is more frequently found in kidneys that are placed in the inverted anatomic position. The surgical procedure is performed without difficulty and at the same time permits us to evidence the presence of a new ureteral revascularization from the recipient after the interruption of vascular supply of the donor kidney.
