Further study details as provided by Yonsei University:

Enrollment: 74
Arms Assigned Interventions
Experimental: Automated cuff-inflator Procedure: Automated cuff-inflator
RIPC protocol consisted of three 10-min cycles of lower limb ischemia at an inflation pressure of 250 mmHg induced by an automated cuff-inflator placed on the upper leg with an intervening 10 min of reperfusion during which the cuff was deflated.

Detailed Description:
Hypothesis : RIPC using tourniquet might be a simple technique with the benefit to provide renal protection without disturbing operating procedure and prolongation of total operating time.
