Impact of Cold Ischemia Time in Clinical Outcomes in Deceased Donor Renal Transplant.

BACKGROUND

Renal transplants (RTs) from deceased donors have increased in Mexico because of the high need of people with terminal kidney damage. The objective of this study is to determine the impact of cold ischemia time (CIT) on clinical outcomes in the deceased donor kidney transplant.

METHODS

A retrospective, observational study of deceased donor RTs performed from 2013 to 2017 in the RT unit of the CMN Siglo XXI was completed. Data were collected from 202 patient records in this period; 7 clinical outcomes were determined, and logistic regression analysis was performed with CIT and extended criteria. The statistical package SPSS version 25 was used.

RESULTS

No risk was observed for clinical outcomes with a CIT of 1080 minutes, risk of delayed function and medical complications was observed with a CIT of 1260 minutes, and risk of surgical complications was observed with a CIT of 1309 minutes. There was a correlation of 0.556 between the Maryland classification score and post-transplant medical complications. The extended criteria are related to risk for death with an odds ratio of 6.91 (95% CI, 2.27-21.01; P = .001) CONCLUSIONS: CIT continues to be an extremely important factor in renal graft survival and post-transplant clinical conditions. The extended criteria represent a considerable risk of death.
