Summary

Kidney warming during transplantation is slow and stays below damaging temperatures. Reducing vascular anastomosis time is crucial for meticulous ex vivo kidney preparation and optimal outcomes.

Area of Science:

  • Nephrology
  • Transplant Surgery
  • Physiology

Background:

  • Kidney temperature management is critical during transplantation.
  • Understanding factors influencing kidney warming is essential for improving graft survival.

Purpose of the Study:

  • To document kidney temperature changes during transplantation.
  • To identify factors affecting kidney warming in transplanted kidneys.

Main Methods:

  • Continuous kidney temperature monitoring during transplantation.
  • Analysis of kidney weight, BMI, warm ischemia time, and post-perfusion temperature.
  • Statistical evaluation of factors influencing kidney temperature and warming.

Main Results:

  • Kidney temperature increased from 1.6°C (container removal) to 6.3°C (recipient placement).

  • Warming speed was dependent on vascular anastomosis time (0.48°C/min) and influenced by kidney weight.
  • Kidney temperature post-reperfusion was significantly correlated with pre-transplant temperature (P<0.0001).

    • Conclusions:

    • Kidney warming during ex vivo preparation is gradual, remaining below the critical 18°C ischemic threshold.
    • Minimizing vascular anastomosis time is vital to reduce warming and optimize ex vivo kidney preparation.
    • Meticulous preparation is necessary to ensure optimal kidney warming and transplant outcomes.
