Renal dysfunction refers to any impairment or abnormality in the function of the kidneys, which are vital organs responsible for filtering waste products from the blood and regulating fluid balance in the body. Common causes of renal dysfunction include kidney disease, infections, and certain medications. Research in this area focuses on understanding the underlying mechanisms of kidney injury, developing new diagnostic tools and treatment options, and improving outcomes for patients with renal dysfunction. This research is crucial for improving the management and prevention of kidney diseases and associated complications.
