Abstract

Acute Kidney Injury (AKI) incidence has increased significantly in the last years, and AKI has emerged as a worldwide health public problem. In fact, AKI has been associated with higher morbidity and early and late mortality, higher hospital length of stay and development of Chronic Kidney Diseases (CKD). In this context, AKI early diagnosis is extremely important to increase protective measures to prevent and minimize the AKI development. Currently, the laboratory diagnosis is based on the increase of the serum creatinine levels. However, serum creatinine changes may occur hours or days after the decrease of the glomerular filtration ratio, and the creatinine concentration is influenced by many non renal factors such as age, muscular mass and metabolism, drugs, hydration and nutritional status, creatinine tubular secretion and gender. Additionally, serum creatinine levels increase only after the decrease of at least 50% of renal filtration reserve. In this context, nowadays there is an intense research trying to identify adequate biomarkers, which can predict an early diagnosis of IRA. This study aim to analyze the efficiency of 12 urinary biomarkers in detecting early changes in renal injury, regarding the development of AKI diagnosed by serum creatinine level criteria in high risk and clinically relevant situations to AKI development: non vascular electives surgeries, moderate to severe trauma and clinical emergencies patients.
