Introduction: Obesity is a worldwide epidemic. The number of overweight renal transplant recipients and cadaveric donors is increasing. We investigated whether donor and/or recipient body mass index correlate with the occurrence of delayed graft function after kidney transplantation.
Materials and methods: Retrospective analysis of 708 consecutive cadaveric kidney transplants between January 2003 and December 2009. Delayed graft function was defined as requirement for more than one dialysis post-transplant dialysis. Impact of body mass index, gender, age, re-transplant, cold ischemia and anastomosis time on the occurrence of delayed graft function were analyzed using uni- and multivariate analyses.
Results: DGF rate was 25,2%, 29.8%, 40,9% and 52,6% in recipients with a body mass index <20, 20-25, 25-30 and >30kg/m2 respectively (p=0,0002). Donor body mass index <20, 20-25, 25-30 and >30kg/m2 resulted in a DGF rate of 22,5%, 31,0%, 37,3% and 51,2% (p<0,0001). Multivariate analysis revealed overweight in the recipient as well as in the donor as an independent risk factor for delayed graft function.
Conclusion: Donor as well as recipient body mass index correlate with the incidence of delayed graft function.
