Lee JH, Won JH, Oh C‐K. Impact of the ratio of graft kidney volume to recipient body surface area on graft function after live donor kidney transplantation. Clin Transplant 2011: 25: E647–E655. © 2011 John Wiley & Sons A/S. : Functioning nephron mass is a determinant of the graft function of kidney transplant recipients. The graft kidney volume and its weight have been reported to be surrogates of the nephron mass. To investigate the impact of the ratios of the surrogates to recipient body surface area (BSA) and body weight on the graft function within six months post‐transplantation, we measured the graft kidney volume, using computed tomography with 3‐dimensional reconstruction before transplantation, and measured the graft kidney weight during surgery. Ninety‐four cases of live donor kidney transplants were included in this study. The graft kidney volume/recipient BSA ratio was correlated with the glomerular filtration rate (GFR) of recipients at one and six months post‐transplantation (r = 0.416, p
