Antioxidants as Renoprotective Agents for Ischemia during Partial Nephrectomy

Abstract EN

Small renal masses have been diagnosed increasingly in recent decades, allowing surgical treatment by partial nephrectomy.

This treatment option is associated with better renal function preservation, in comparison with radical nephrectomy.

However, for obtaining a bloodless field during surgery, occlusion of renal artery and veins is often required, which results in transitory ischemia.

The renal ischemia-reperfusion injury is associated with increased reactive oxygen species production leading to renal tissue damage.

Thus, the use of antioxidants has been advocated in the partial nephrectomy perioperative period.

Several antioxidants were investigated in regard to renal ischemia-reperfusion injury.

The present manuscript aims to present the literature on the most commonly studied antioxidants used during partial nephrectomy.

The results of experimental and clinical studies using antioxidants during partial nephrectomy are reported.

Further, alimentary sources of some antioxidants are presented, stimulating future studies focusing on perioperative antioxidant-rich diets.
