Living Donor Renal Transplantation in Catalonia: Overall Results and Comparison of Survival With Cadaveric Donor Renal Transplantation

Abstract

Objectives To describe the general characteristics of living-donor renal transplantation (LRT) in Catalonia, and to compare results with those of the cadaveric donor renal transplant (CRT). Results Four hundred seventy-three LRTs have been performed in Catalonia since 1965. Transplantations carried out between 1980 and 2003, according to the RMRC data, were reviewed. The most frequent degrees of kinship are parents–children (48%), spouses (22%), and siblings (18%). Around 68% of the donors were women. Around 56% of recipients were men. The transplant was advanced in approximately 30% of the cases. The mean cold ischemia was 2 hours. Seven percent showed delayed graft function (DGF). Forty-nine percent of the patients had glomerular filtration >60 mL/min after 1 year. Patient survival at 1, 5, 10, and 20 years were 99%, 97%, 93%, and 82% in LRT; and 96%, 90%, 80%, and 62% in CRT ( P < .00001). Graft survivals over the same periods were 91%, 76%, 58%, and 32% in LRT, and 85%, 69%, 49%, and 23% in CRT ( P = .00008). The graft mean life was 12 years (LRT) and 10 years (CRT). Graft survivals, censoring deaths over the same periods, were 93%, 79%, 62%, and 39% in LRT, and 89%, 77%, 62%, and 37% in CRT ( P = .3). Mean life was 14 years in both cases. The recipients mean age was 31 (LRT), and 44 years (CRT), whereas the donor mean age was 51 (LRT), and 42 years (CRT). Conclusions LRT results were excellent both regarding DGF and patient and graft survivals. They were not comparable to CRT due to the different characteristics of the recipients. LRT is a good solution to reduce waiting lists.
