BackgroundThe evaluation of a potential living kidney donor (LKD) leads to exclusion of at least 50 % of candidates. The aim of this study was to analyze the reasons for exclusion of potential LKDs referred to our center.MethodsWe retrospectively analyzed historic and clinical data of all potential LKDs who were evaluated over 7 years from January 2005 to March 2012. Data were obtained by review of an electronic database.ResultsAmong 79 (50 female, 29 male) candidates, 24 (30.3 % ) successfully donated, comprising 22 related and 2 unrelated donors. We excluded 45 (56.9 % ), and 10 (12.6 % ) are actively undergoing evaluation. Reasons for exclusion were medical (n?= 14; 31 % ), nonmedical (n?= 18; 40 % ), positive cross-match (n?= l7.7 % ), pregnancy (n?= 2; 4.4 % ), and other reasons (n?= 3; 6.6 % ). Of the 14 donors excluded for medical reasons, 75.8 % were due to diabetes, cardiovascular disease, hypertension, or obesity and 21.5 % to inadequate renal function, malignancy, or liver disease. Of the 18 (40 % ) excluded for nonmedical reasons, 6 (33.3 % ) were because the intended recipient received a deceased-donor transplantation before the evaluation could be completed, 5 (27.7 % ) because the recipient was no longer a candidate for transplantation, 5 (27.7 % ) because of donor withdrawal, and 2 (11.1 % ) for other reasons.ConclusionsPositive cross-match and deceased-donor transplantation during the evaluation process were the 2 most common reasons for LKD exclusion. Evaluation of potential LKDs is time consuming, requiring a remarkable amount of human and material resources. A dedicated pathway for the diagnostic work-up of LKDs may speed- the evaluation process and improve its efficiency, use of ABO-incompatible or paired-exchange donations may increase the yield of donor organs.
