Hyperspectral imaging is a real-time noninvasive method to assess renal oxyhemoglobin saturation intraoperatively throughout the kidney. A nadir percent of oxyhemoglobin is attained within 10 minutes of hilar occlusion. This knowledge may allow future surgical or pharmacological interventions that titrate or minimize ischemic injury in real time.

Baseline renal oxygenation, as measured with HsI, may help predict risk of postoperative renal insufficiency and may distinguish between patients with otherwise similar baseline characteristics, such as eGFR. HsI may provide individualized assessment of renal function to influence intraoperative decision-making to help preserve renal function.
