Review Article: Acute Kidney Injury

Acute kidney injury (AKI) is described as a loss of excretory renal function that occurs suddenly. AKI is one of a group of diseases and disorders known as acute kidney diseases and disorders (AKD), in which a gradual loss of kidney function or persistent renal dysfunction is linked to the irreversible loss of kidney cells and nephrons, which can lead to chronic kidney disease (CKD). New biomarkers are currently being explored in the clinic to detect damage before function loss. People all throughout the world are affected by AKI and AKD. Infections and hypovolaemic shock are the most common causes of AKI in low- and middle-income nations. Infections, drugs, or invasive procedures cause AKI, which is more common in elderly hospitalized patients in high-income countries. Infections are widespread in all areas, as are AKI and AKD caused by trauma. The large range of symptoms associated with AKI suggests a number of pathophysiological reasons. In critical care settings, AKI management can be difficult, especially when it comes to volume control, nephrotoxic medication management, and when it comes to the timing and kind of renal support. Conclusion: AKI is a significant medical disorder that has been linked to poor clinical outcomes in individuals who are hospitalized. Significant progress has been made in refining the definition of this syndrome and establishing the underlying pathophysiologic processes of the many clinical manifestations. It is self-evident that no single pathophysiologic mechanism can account for all clinical symptoms of AKI.
