Kidney injury refers to damage or dysfunction of the kidneys, which can be caused by various factors such as infections, medications, toxins, or underlying health conditions. The kidneys play a crucial role in filtering waste products and excess fluids from the blood to form urine, so any impairment in their function can lead to serious health complications. Research in the area of kidney injury focuses on understanding the mechanisms underlying kidney damage, identifying risk factors for kidney injury, and developing new diagnostic tools and treatment strategies to prevent or manage kidney damage. This research is crucial for improving outcomes for patients with kidney injury and reducing the burden of kidney disease on healthcare systems.
