Implementation of Intraoperative Hyperspectral Imaging in Kidney Transplant Surgery

Abstract

Intraoperative hyperspectral imaging (HSI) provides a non-contact, quantitative method to assess tissue oxygenation and perfusion during kidney transplantation. Within the TESIT study, a standardized five-timepoint (T1-T5) HSI protocol was integrated into the surgical workflow. Early results show a pronounced post-reperfusion increase in StO? and NIR values, clear perfusion differences between living and deceased donor grafts. These findings highlight the feasibility and clinical potential of HSI to detect perfusion abnormalities in real time and to support improved intraoperative graft assessment.
