Background: In adult (Living donor liver transplantation) LDLT, donor safety is of paramount importance, and ideally, there should not be any donor deaths. Objectives: To assess the prognosis of donor laboratory and clinical data according to the remnant liver volume. Patients and methods: The present study conducted on 200 consecutive cases of living donor liver transplantation over a period of 7 years (2012 and 2018). Patients were divided to two groups according to remnant liver volume (RLV): group (A) 60 patients with 30% to less than 35% RLV, while group (B) 140 patients with RLV more than or equal 35%. Results There were statistically significant difference between both studied group among ALT, total bilirubin and serum albumin. Conclusion: Right lobe donor hepatectomy can be performed with remnant liver volume of less than 35% with low risk on donor.
