Remote ischaemic preconditioning (RIPC) is a strategy to protect a target organ against ischaemia-reperfusion injury (IRI) by inducing short-term ischaemia/reperfusion (I/R) in a remote organ. RIPC of the kidney by temporary limb occlusion would be a safe, inexpensive and noninvasive method to prevent renal damage in, e.g., transplantation and aortic surgery. We investigated whether brief hind limb occlusion can protect against renal IRI and whether this protection is adenosine dependent.


Rats underwent either no RIPC, unilateral RIPC or bilateral RIPC. The preconditioning stimulus was either continuous (12'/12' I/R) or fractionated (three times 4'/4' I/R). After the last reperfusion period, we induced 25' ischaemia in the right kidney.


After 24 h of reperfusion, renal function was improved by 30-60% in both bilateral RIPC groups and in the fractionated unilateral group. Renal tubule damage and kidney injury molecule-1 expression were reduced in three of four RIPC groups. Treatment with the adenosine receptor blocker 8-(p-sulfophenyl)theophylline had no effect on fractionated or continuous RIPC.


Brief hind limb ischaemia induces protection against renal IRI, which makes this a promising strategy to prevent renal IRI in a clinical setting. Bilateral RIPC was more effective than unilateral RIPC, and this protection occurs via an adenosine-independent mechanism.
