Pairs of Kidneys Transplanted From the Same Donor: Is There Any Difference?

The aim of this study was to compare the evolution of the first kidney in relation to the second kidney transplanted from the same donor, focusing on the impact that a longer cold ischemia time may have as an independent variable.
Material and Methods: The study included 44 pairs of kidneys transplanted from the same donor between February 2008 and October 2010, divided into Groups 1 and 2 according to the graft placement order. The variables analyzed were age, sex, comorbidities, number of transfusions, length of hospital stay, maximum peak PRA, immunologic incompatibility, ischemia time, delayed graft function (DGF), presence of rejection, creatinine clearance at first week, at 3 months and at 1 year, and vascular and tract complications in each group.
Results: The mean cold ischemia time was 15.6 hours in Group 1 and 20.1 hours in Group 2 (P < .001). The average recipient age was 52.79 years in Group 1 and 54.52 years in Group 2, with an equal sex ratio in the two groups; an average of 2.06 PRC were transfused prior to transplantation in Group 1 and 0.93 PRC in Group 2; the average length of stay was similar in the two groups. Major DR incompatibility was only found in Group 2 (P < .03). Creatinine clearance at first week, DGF and acute rejection showed worse results in Group 2, but these differences were not significant. Vascular complications were present in 4.5% and 2.3% of Groups 1 and 2, respectively, and tract complications were 6.8% and 11.4%.
Conclusions: A greater tendency to DGF, early rejection and tract complications were found in the group with longer ischemia time, although the difference was not statistically significant. Larger series will be necessary to confirm our results (read more). Print this post
