One of the targets of expanding criteria for kidney donation is BMI. As the impact of BMI differs in Asians, we studied the long-term effect of BMI in Asian living donors.

Donors in our prospectively collected database with a follow-up longer than 3 years were evaluated. Donors with a preoperative eGFR lower than 80ml/min/1.73m², history of hypertension or diabetes were excluded.

384 donors were included in the study. There were 291 donors with a low BMI(<25, group A), and 93 donors with a high BMI(≥25, group B). The postoperative eGFR of group B was significantly lower until 2 years after donation, but was not significantly different after 3 years. Simple linear regression analysis of each period revealed age, BMI, preoperative eGFR, blood pressure, total and LDL cholesterol, triglyceride, glucose, uric acid as significant factors. After multiple regression analysis of these factors, BMI was a significant factor until 1 year post-donation but not afterwards. Age and preoperative eGFR were constantly significant factors and uric acid level was a significant factor after 2 years. Of note there were only 4 donors with a BMI higher than 30ml/min/1.73m² included in the study.

In conclusion, BMI of asian donors only affected the renal function in the short term post-donation period and did not affect renal function 2 years afterward.
