Acute kidney injury (AKI) is a relatively frequent complication after coronary artery bypass graft surgery (CABG). We compared the off- and on-pump CABG procedures with respect to changes in renal function as reflected by levels of urine neutrophil gelatinase-associated lipocalin (UrNGAL). ⋯ According to the UrNGAL measurements, neither of the two CABG techniques was superior in terms of their effect on postoperative renal function. Renal function significantly improved in the on-pump group while UrNGAL levels decreased after surgery in the same group.
