Background: Due to organ shortage, it is not easy to find an ideal donor in renal transplantation. To enhance donor pool, marginal donors can be acceptable even in living renal transplantations. We compared optimal and marginal donor transplantations in terms of graft and patient survival.
Methods: We performed 32 living related renal transplantations, 11 of which were from marginal donors, from January 1999 to December 2000. Recipients from optimal and marginal donors were compared in terms of renal function, acute tubular necrosis (ATN) and acute rejection (AR) rates.
Results: Although mean serum creatinine level in the seventh day was found to be higher in the recipients from marginal donors (1,88 mg/dl vs. 2,51 mg/dl); it did not reach to a statistical difference (p=0.1). Serum creatinine levels after thirtieth day, ATN and AR rates were statistically similar in both groups, as well. In optimal and marginal groups, 3-year graft survival rates were found to be 85 and 72 percent respectively (p= 0.72). 3-year patient survival rates were also found to be similar in both groups (90 % vs. 91 %) (p= 0.91).
Conclusion: Functional and survival results in the transplantations from marginal donors were as good as from optimal donors. So, we thought that marginal donors could be used safely with a good preoperative evaluation to increase donor pool.
