Kidney exchange transplantation current status, an update and future perspectives

Table 3 Key features of national kidney exchange program

Country[3-10]	Key features of kidney exchange program
Australia[3-4]	High transplant rate for highly sensitized, HLA-incompatible pairs due to accepting ABO-incompatible donor matching with ABO titers ≤ 1:64, high-resolution HLA identification and virtual cross match
Canada[5]	Non-directed anonymous donors facilitate 62% of transplants
South Korea	Favourable due to less sensitized, more compatible pairs, more non-directed anonymous donors, non-O > O patients
United Kingdom[8]	Low transplant rate due to less use of altruistic donor, restriction on long chain, permit only ≤ 3-way exchange, donor travel
Johns Hopkins University, United States	Kidney exchange + desensitization increases transplant rate for difficult to match and difficult to desensitize pairs
San Antonio, United States[10]	Use of compatible pairs and A2 donors increases transplant rate even in single canter program
National kidney registry, United States	Longer chain are used in matching
Donor vs kidney transport	Donors travel is preferred in Netherlands and Canada, kidney transport is preferred in United Kingdom and Australia
Alliance for paired donation, United States	Global kidney exchange
