Background and Aim: The incidence of obesity is increasing in Asian Race and Vietnam is no exception. In this study we compare the early postoperative complications of living kidney donors between a body mass index (BMI) over 23 and BMI under 23;  between only one renal artery and multiple renal arteries that performed transperitoneal laparoscopic living donor nephrectomy by a team of surgeon. transperitoneal laparoscopic living donor nephrectomy
Materials and Methods: All case of transperitoneal laparoscopic living donor nephrectomies were performed from April 2017 to October 2017 at Urology Department, Choray Hospital by a team of surgeon. We analyse demographic data,  BMI, creatinine of preoperative values and at discharge, GFR of preoperative value, mean operative time, mean blood loss, mean warm ischemia time, mean postoperative stay, complication of intraoperation and postoperation, time of intestinal peristalsis return.
Results: 25 cases for during this period,  18 of whom had only one renal artery (group A1), whereas 07 had multiple renal arteries (group A2); 15 of whom had a BMI below 23 (group B1), whereas 10  had a BMI of 23 or higher (Group B2). Mean age 50,32 10,3 (26-66) years, and 25 cases in left kidney, ratio of male/female 13/12,  mean BMI 22,3  1,9 (18,4 - 26,8), creatinine of preoperative values 1,0 0,13 (0,6 - 1,3) mg%, and 1,1  0,16 (0,88 – 1,5) mg% at discharge, GFR of preoperative value 44,4 3,4 (39,4 - 54,7) ml/min, mean operative time 137 21,3 mins, mean blood loss 44 14,7 ml, mean warm ischemia time 5,64  3,9 (4 – 24) mins, mean postoperative stay 3,4 1,5 (2 - 5) days, no need for blood transfusion or open conversion, time of intestinal peristalsis return 2,04  0,77 (1 – 3) days. No complications were observed in these groups. There is no significant different mean operative time, mean warm ischemia time between group A1 and group A2 (p=0,18; p=0,19); between group B1 and group B2 (p=0,35; p=0,85).
Conclusions: High BMI donors and the side of kidney with multiple renal arteries do can safely donate their kidney with no significant increase in complication rates.
