Histopathologic changes during chronic small bowel allograft rejection.

Renal transplantation is the main treatment for end-stage renal disease and has rapidly increased in number over the past 3 decades, leading to an increasing need for organs. The disparity between organ access and the number of patients on the waiting list has led transplant surgeons to use marginal cadaveric donors. As a consequence, the concept of “marginal cadaveric kidney donor” has been developed.We retrospectively evaluated 120 patients who received kidneys from cadaveric donors between September 2009 and August 2021. The donors were divided into standard and marginal cadaveric donors, and their age, sex, cause of death, criteria of acceptance as marginal donors, and Kidney Donor Profile Index (KDPI) were recordedThe donors included 69 men and 51 women, with a mean age of 52.9 ± 16.8 years. There were 52 standard donors and 68 marginal donors. Graft and donor survival were compared based on the KDPI values of the donors, and were respectively found to be higher in those with a KDPI of 0 to 60 than in those with a KDPI of 81 to 100 (P = .011 and .039, respectively). There was no significant difference between those with a KDPI of 61 to 80 and the other groups.Expanded criteria donor organs, which offer greater survival benefits than hemodialysis, can be used safely to meet the increasing need for donors. Expanded criteria donor organs should thus be considered a valuable alternative in this patient group.
