Primary Outcome Measures

Name	Time	Method
changes in blood cystatin c levels during timepoints <br>[preoperative, postoperative 2 hour (primary timepoint) and postoperative 24 hours];changes in blood creatine levels during timepoints[preoperative, postoperative 2 hour( primary timepoint) and postoperative 24 hours]

Secondary Outcome Measures

Name	Time	Method
Measurement of the operation time in minutes with the stopwatch[time between start and end of operation];measurement of the time until the removal of cross clamp with the stopwatch[time between start and end of operation];measurement of urine output in ml by weighing of urinary catheter bag,[hourly urine output over a 24-hour period];measurement of mediastinal drainage volume in ml by weighing of mediastinal chest tube[mediastinal drainage volume over a 24-hour period];measurement of the time between taking the patient to the intensive care unit and extubating with the stopwatch [as long as the patient is in intensive care];changes in blood urine nitrogen (BUN) levels during timepoints[preoperative, postoperative 2 hour( primary timepoint) and postoperative 24 hours]
