Abstract Content

Introduction

To evaluate the effects of second warm ischemic time on delayed graft function in kidney transplant.

Materials and Methods

Patients with kidney transplantation done at Princess Margaret Hospital from January 2020 to December 2024 were recruited. Demographic data, cold ischemic time, second warm ischemic time and occurrence of delayed graft function were retrospectively collected and analyzed.

Results

78 patients with 42% female were recruited. The mean age was 48.1 +/- 13.9. The mean operation duration was 226 +/- 46 mins, with average estimated blood loss of 314.8 ml. The mean cold ischemic time and second warm ischemic time were 828.4 +/- 417.6 and 45.0 +/- 12.8 mins respectively. 12 patients (15.4%) developed delayed graft function with significant longer cold ischemic time (1048.4 VS 792.8 mins) but similar second warm ischemic time (44.2 VS 45.1 mins), compared to those without delayed graft function.

Conclusions

Our retrospective review demonstrated longer cold ischemic time but not second warm ischemic time contributed to delayed graft function. Due to small number of cases and confounding factors, the exact effect of second warm ischemic time and any safety threshold on delayed graft function requires more large-scale studies.
