Objective:  The retrospective evaluation of graft loss, living status and 1-month, 3-month, 6-month and 12-month creatinine values of post-transplant recipient recipients in kidney transplants transplanted from cadaveric marginal kidney donors to non-marginal and marginal cadaver kidney donors, it is aimed to find the relationship between donors.
Method: The brain death notification form made in the Bursa Organ and Tissue Transplantation Coordination Center in 2011-2015 was obtained from donor information forms of family donations and organ donors. Demographic data and etiology of donors were determined. Serum creatinine> 1.5 mg / dL, HbsAg - Anti - HCV - HIV positive patients, BMI 40, Intensive Care Unit> 5 days, Cold ischemia time> 30 hours, Active infection status, Marginal renal donor criteria were determined.
Findings: During the research period, brain death was reported in 748 cases in Bursa Organ and Tissue Transplant Coordination Center. the number of brain deaths donated was 249 (33.3%).  Uludag University Health Practice and Research Center Directorate Organ transplantation center was evaluated with 161 kidney donors using kidney. There are 128 marginal and 33 non-marginal cases from these donations. There were no cases with a BMI> 40 or more. 36 of the cases were> 60 ages (22.3%). There was no HBsAg (+) anti-HCV (+) and HIV (+) donor. Intensive care time  hospital stay> 5 days 42 (26 %). Active infection was detected in 22  (13,66 %). The amount of serum creatinine was> 1.5 mg / dL in 59 (36,6%). 128 cases  marginal in.  and 31 cases died. The number of cases that died after 1 year from marginal donor donors is 17.  17 cases of the marginal cadaver kidney donors was lost grafts within one year.  There is no graft loss in non-marginal cases, no significant correlation was found when p> 0,05 in the mann - whitney test of 6 - month creatinine values ​​of renal transplant recipients from marginal donors and from non-marginal cases. This suggests that there is no difference between kidney transplants made from marginal donor donors and made from non-marginal kidney donors.
Conclusion: The rate of organ donation in Turkey is below the national average in the brain death declaration. However, the marginal donor utilization rate is satisfactory. This may be due to broad marginal criteria. The fact that there is no difference between marginal and non-marginal cases of the cases can be explained by applications that increase the number of marginal donors in Turkey.
