Method:

The level of serum creatinine, urinary L-FABP, NGAL and NAG before and after surgery of 85 patients who underwent cardiovascular surgery, were deducted. This population was divided according to AKIN criteria into 2 groups with or without AKI development and above parameters were examined.

Results:

Urinary L-FABP level just right after surgery and 3 hours after intervention in AKI group, has significantly increased comparing its level before the surgery. Also the comparison of L-FABP level between AKI and non AKI groups shows that its level is significantly high in AKI group. This results shows that urinary L-FABP is able to determine risk of developing AKI in early stage.
