Postoperative renal function recovery is very important to value the operation quality after
kidney transplantation. Dexmedetomidine is a selective alpha-2 agonist,enhances urine flow
rate and perioperative renal function. Some animal experiments have revealed its beneficial
effects against ischemia-reperfusion injury (IRI), our goal is therefore to investigate the
effectiveness of a recipient treatment with Dexmedetomidine during operation at reducing
Cystatin C level and enhancing renal function after kidney transplantation.
