Kidney and recipient weight incompatibility reduces long-term graft survival
Long-term function of kidney allografts depends on multiple variables, one of which may be
the compatibility in size between the graft and the recipient. Here, we assessed the long-
term consequences of the ratio of the weight of the kidney to the weight of the recipient
(KwRw ratio) in a multicenter cohort of 1189 patients who received a transplant between
1995 and 2006. The graft filtration rate increased by a mean of 5.74 ml/min between the third
and sixth posttransplantation months among patients with a low KwRw ratio (< 2.3 g/kg; P< …
