Acute kidney injury (AKI), which is commonly caused by sepsis and contributes significantly to worldwide mortality, may affect patient outcomes and increase the risk of chronic disease. This review examines how urinary biomarkers can forecast renal recovery following sepsis. Conventional AKI diagnostics, like serum creatinine, suffer from delayed detection and poor specificity. Newer urinary biomarkers, such as neutrophil gelatinase-associated lipocalin (NGAL) and cell-free DNA (cfDNA), show potential for earlier detection and improved prognosis. NGAL, noted for its sensitivity to nephrotoxic and ischemic insults, shows potential in predicting AKI onset and recovery. Similarly, cfDNA levels, reflecting systemic cell death, correlate with sepsis severity and renal outcomes. Despite their promise, variability in biomarker levels due to comorbidities and the need for standardized diagnostic thresholds remain challenges. Combining multiple biomarkers may enhance diagnostic accuracy, offering a more comprehensive assessment of kidney function and sepsis-induced AKI (S-AKI). Further research is needed to validate these biomarkers and integrate them into clinical practice for improving patient outcomes post-sepsis.
