| 概要 | Optimizing nephron supply to recipient demand is a non-immunologic determinant of renal allograft outcome. Nephron reduction is usually caused by physical donor-recipient mismatch, but its pathologic relevance remains to be determined.
METHODS: Thirty-one recipients of living donor renal transplants were divided into three subgroups: those who received transplants from the same gender (n = 6, Group 1) and those who underwent male-to-female (n = 8, Group 2) and female-to-male (n = 17, Group 3) transplants. Renal mass was evaluated by three-dimensional computed tomography (3D-CT) volumetry before and one year after transplantation. Glomerular volume was determined from protocol biopsies obtained one hour and one year after transplantation. RESULTS: Histologically determined glomerular volume in biopsied tissues showed a significant linear correlation with allograft size on 3D-CT volumetry (p < 0.001, r = 0.625). Mismatches in body weight, glomerular volume and kidney volume ratios were significantly greater in female-to-male (Group 3) than in male-to-female (Group 2) transplants (p < 0.001 each). Despite the two groups having nearly equal graft filtration rates one year after transplantation, proteinuria rate was three-fold higher in Group 3 than in Group 2 (p < 0.001). CONCLUSION: These findings suggest that too small graft size, frequent in female-to-male transplants, could cause hypertrophy in both kidneys and glomeruli, thereby affecting allograft function and survival.
