BACKGROUND Decreased renal blood flow plays a vital role in the etiology of acute kidney injury (AKI). In this study, we aim to investigate the role of renal regional oxygen saturation (rSO2 ) reductions in predicting AKI in the first 24 hours of life. METHODS One-hundred premature babies with a gestational age of ≤32 weeks were included. Renal and cerebral rSO2 s were monitored for 24 hours by near-infrared spectroscopy (NIRS). Infants were followed up for the first 7 days for the diagnosis of AKI. RESULTS Infants' median gestational age was 29 (23-32) weeks, and their birth weight was 1192 ± 355 g. It was found that the renal rSO2 values were lower in the first 24 hours of life in patients who developed AKI, and this decrease was statistically significant in the first 6 hours of life. CONCLUSION The low renal rSO2 values in the early hours of life in premature babies may have a role in predicting AKI.
