Minimal arterial in-flow protects renal oxygenation and function during porcine partial nephrectomy: confirmation by hyperspectral imaging.

Objectives: To examine the potential for renal protection through incomplete renal artery (RA) occlusion with both assessments of creatinine changes and the use of hyperspectral imaging to monitor tissue oxygenation. Renal ischemia during partial nephrectomy can have adverse consequences on renal function.

Methods: Fourteen pigs with a solitary kidney underwent open partial nephrectomy with warm ischemia.
