Chronic kidney disease is increasingly more prevalent worldwide, and kidney transplant remains the best option for patient survival. Living kidney transplants (LKT) pose advantages over deceased donor transplants, such as longer graft survival, lower ischemia time, and better HLA match. However, LKT is not always attainable for multiples reasons, with the absence of a suitable living donor being a significant barrier.

Therefore, meticulous donor screening must be performed in order to guarantee donation safety. We examined medical appointments of living kidney donors evaluated at Hospital do Rim, São Paulo, between January and December 2020. Reasons for not proceeding with the donation were evaluated and were categorized as medical, surgical, immunological, psychosocial, or other. A total of 506 donor‑receptor pairs were enrolled for evaluation during the study period. More than half of screened donor‑receptor pairs (N=296, 58.5%) were not considered feasible for LKT. The primary cause for refusal was medical contraindication (32.1%), followed by immune (21.3%) and social (19.3%) causes.

In addition, a considerable proportion of patients voluntarily withdrew themselves at variable time points during the evaluation process (N=79). In our center, most patients did not meet the criteria for kidney donation owing to medical reasons, similarly to other centers, and this reflects the importance of meticulous donor screening. In addition, the current Covid‑19 pandemic affected the living transplant program, contributing to delayed complete donor and receptor evaluation.
