Characteristics of potential living kidney donors and recipients: donor disqualification reasons--experience of a Polish center.

ABSTRACT

INTRODUCTION: Kidney transplantation is efficacious as a renal replacement, particularly pre-emptive living donation. In Poland, the rate of transplantation of living donor kidneys is only 3%. The aim of the study was to identify the most common reasons to disqualify a potential living kidney donor. METHODS: We evaluated 124 kidney donor candidates for 111 potential recipients at 1 medical center for genders and ages of donor and recipient; thus relation, donor disqualification reasons, number of potential donors for a particular recipient, prior transplantations, and kidney vasculature. RESULTS: The 111 recipients of ages 2-62 years had, 1, 2, or 3 potential donors were tested in 101, 1, and 7, cases respectively. We had 18.9% recipients referred for pre-emptive transplantation; 59.5% were on haemodialysis and 21.6% on peritoneal dialysis. In all, 89% recipients sought first kidney transplantations. Kidneys were procured from 49/124 (39.5%) of the initially evaluated donors. The full examination was completed by 92 potential donors with 68/124 donors disqualified early. Single and multiple renal arteries were detected in 56 and 36 potential donors, respectively. Donor disqualification was due to medical contraindications (39.7%), earlier transplantation from a deceased donor (25%), immunologic constraints (23.5%), donor consent withdrawn (6%) or psychological and social reasons (4.4%). CONCLUSIONS: A considerable number of donor candidates are disqualified for medical reasons.
