Living donation for kidney transplantationis being promoted due to the shortage of organs, theimproved outcomes of living donor transplants and theevolution of immunosuppression regimens. The processof organ donation from a living donor affects not onlymedical-surgical features but also emotional, social andeconomic. Using kidneys from living donors involves agreat responsibility in evaluation and selection.Candidates for donation undergo an extensive set ofexaminations in order to optimize selection and to plansurgery. Radiological evaluation is one of the mostimportant features of the evaluation process and selectionof the kidney; it shows precisely the renal vascular anatomy, which is decisive in the choice of the kidneyand helps to optimize the process and diminish risks andcomplications during extraction and/or transplantation.The advantages on imaging tests allow to evaluatepotential donors in a safely, fast and almost noninvasive matter. The aim of the process is to select the kidneywith less likelihood of failure due to technical reasons,and always leave the best kidney for the donor.
