Background: This study aims to compare the conventional coronary artery bypass graft (CABG) surgery and on-pump beating heart bypass grafting (OPBHB) with respect to acute kidney injury and subsequent dialysis requirement.

Methods: Between January 2012 and October 2013, medical records of 77 patients who underwent conventional CABG and 76 patients who underwent OPBHB for coronary artery disease in our clinic were retrospectively analyzed.

Results: There was no significant difference in preoperative renal function test results between the groups. However, there was a significant difference in cardiopulmonary bypass time and length of intensive care unit stay (p<0.05). Seven (9.21%) of 76 patients in OPBHB group and 11 (14.28%) of 77 patients in CABG group developed acute kidney injury; however, it did not indicate a statistically significant difference between the groups (p>0.05). One patient in OPBHB group and four patients in CABG group also needed dialysis.

Conclusion: Our study results suggest that OPBHB is superior to the conventional CABG in terms of acute kidney injury and, more importantly, development of acute renal failure in patients with a serum creatinine level of 1-1.3 mg/dL.
