Abstract

Introduction: Either deceased or living-related renal transplantation constitutes the best therapeutic option for patients with end-stage renal disease. In this retrospective study, an attempt to identify parameters that affect allograft survival in living donor renal transplantation was made.

Methods: Between January 2000 and July 2012, 478 adult patients received a renal transplant from a living-related donor in our center and their records were retrospectively reviewed in November 2012. Data concerning donor age, recipient age, donor/recipient age difference, donor/recipient gender, and ABO compatibility/incompatibility were recorded and associated with renal allograft survival rate.

Results: Renal allograft survival rate was 96%, 89.5%, and 77.7% in the first, fifth, and 10th yr after transplantation, respectively. Only the difference between donor and recipient age was statistically significant in relation to graft survival. In cases with age difference >13 yr, graft survival rate was lower from the third yr onward.

Conclusions: Only the age difference between donor and recipient exerts an adverse impact on graft outcome after living donor renal transplantation, whereas donor age, recipient age, donor/recipient gender, and ABO incompatibility do not significantly influence renal allograft survival.

Keywords: age difference; living donor; renal allograft survival; renal transplantation.
