Introduction: Long-term studies of live kidney donors have shown that living kidney donation is safe and rarely affects the individual's health. However, there are a few references about which kidney donor selected. Kidney Disease Improving Global Outcomes (KDIGO) recommends a significant (>10%) difference in split renal function between the two kidneys, the kidney with lower function should normally be used for transplantation. Our aim was to study the split renal function as measured by DTPA in live kidney donors and its impact on kidney selection decision.

Methods: From January 2008 to May 2015, 430 living kidney donors were enrolled. All donors underwent preoperative DTPA. We divided recessive side kidney donor group and dominant side kidney donor group. Live kidney donors who gave the dominant side were spilt into a difference of 7%, 8%, 9% and 10%. Moreover, renal function was compared according to the time. Continuous and categorical variables were compared using ANOVA in the 3 groups.

Results: There were no differences in demographics and eGFR between 3 groups a disparity in 7%, 8%, 9% and 10%. The renal function at 6^th month were 64.02±11.34, 63.98±14.00 and 64.43±15.58 in the group of 7% disparity (p=0.970). 64.02±11.34, 64.45±14.51 and 62.04±7.60 in group of 8% disparity (p=0.494). 64.02±11.34, 64.42±14.38 and 61.79±7.27 in group of 9% disparity (p=0.481). 64.02±11.34, 64.43±14.18 and 60.85±7.32 in group of 10% disparity (p=0.338). There was no effect on renal function in dominant side kidney donor compared to recessive side.Conclusion: There was no difference in renal function after dominant side kidney donor up to 10% when determining the donor aspect with the split renal function.
