Acute Kidney Injury (AKI) Risk Factors

Flashcards
0/12
Liver Disease
Cirrhosis and other liver conditions can alter renal blood flow regulation and result in hepatorenal syndrome, a type of AKI.
Contrast-Induced Nephropathy
IV contrast used in imaging procedures can cause direct tubular cell toxicity and ischemia, leading to intrinsic AKI.
Sepsis
Systemic infection leads to widespread inflammation, causing vasodilation and hypotension, which impairs renal blood flow.
Rhabdomyolysis
The breakdown of muscle tissue releases myoglobin into the bloodstream, which is toxic to renal tubular cells and can cause intrinsic AKI.
Urinary Tract Obstruction
Obstructive uropathy causes increased intraluminal pressure and obstructs urine flow, leading to postrenal AKI.
Dehydration
Insufficient fluid intake or excessive fluid loss can lead to hypovolemia, reducing renal perfusion and causing prerenal AKI.
Advanced Age
Reduced renal reserve and a decrease in the regenerative capacity of the kidneys make older adults more susceptible to AKI.
Autoimmune Diseases
Disorders like lupus can cause immune complex deposition in the kidneys' filtering units, leading to glomerulonephritis and AKI.
Diabetes Mellitus
High blood sugar levels damage blood vessels in the kidneys, impairing renal function.
Hypertension
Chronically high blood pressure can strain the renal arteries and lead to kidney damage.
Heart Failure
Reduced cardiac output decreases renal blood flow and can lead to ischemic injury to the kidneys.
Exposure to Nephrotoxic Drugs
Certain medications cause direct toxicity to kidney cells, leading to intrinsic AKI.
