Drone‐Assisted Organ Transport: A Scoping Review of Clinical, Regulatory, and System Readiness

open access: yesClinical Transplantation, Volume 39, Issue 12, December 2025.
ABSTRACT Organ transport remains a critical determinant of transplant success, with delays during transfer prolonging cold ischemia time (CIT) and increasing the risk of delayed graft function or organ discard. Uncrewed aerial vehicles (UAVs) have emerged as a potential means to enhance the speed, predictability, and resilience of transplant logistics.
