Renal insufficiency is poor function of the kidneys that may be due to a reduction in blood-flow to the kidneys caused by renal artery disease. It is poor function of the kidneys that may be due to a reduction in blood-flow to the kidneys caused by renal artery disease. Normally, the kidneys regulate body fluid and blood pressure, as well as regulate blood chemistry and remove organic waste.
renal insufficiency. see renal dysfunction (above). renal ischemia. a significant cause of renal dysfunction and cortical and medullary necrosis. Is usually part of a general state of shock, dehydration and severe toxemia.  renal failure, inability of the kidneys to excrete wastes, concentrate urine, and conserve electrolytes. The condition may be acute or chronic. Acute renal failure is characterized by oliguria and the rapid accumulation of nitrogenous wastes in the blood (azotemia). Renal failure. Disorder characterized by the kidney's inability to filter wastes from the blood. It may be acute (occuring suddenly and usually reversable) or chronic (developing slowly over time as a result of permanent damage). renal failure. n. Acute or chronic malfunction of the kidneys resulting from any of a number of causes, including infection, trauma, toxins, hemodynamic abnormalities, and autoimmune disease, and often resulting in systemic symptoms, especially edema, hypertension, metabolic acidosis, and uremia. Renal failure. Disorder characterized by the kidney's inability to filter wastes from the blood. It may be acute (occuring suddenly and usually reversable) or chronic (developing slowly over time as a result of permanent damage). Kidney Failure. Kidney failure is when your kidneys stop working well enough for you to live without dialysis or a kidney transplant. Kidney failure can happen very suddenly (called acute renal failure) or slowly over time.  Description. Renal insufficiency is poor function of the kidneys that may be due to a reduction in blood-flow to the kidneys caused by renal artery disease. Normally, the kidneys regulate body fluid and blood pressure, as well as regulate blood chemistry and remove organic waste. Renal insufficiency. Renal insufficiency is poor function of the kidneys that may be due to a reduction in blood-flow to the kidneys caused by renal artery disease. Symptoms. Signs and symptoms of acute kidney failure may include: 1  Decreased urine output, although occasionally urine output remains normal. 2  Fluid retention, causing swelling in your legs, ankles or feet. 3  Drowsiness. 4  Shortness of breath. 5  Fatigue. 6  Confusion. 7  Nausea. 8  Seizures or coma in severe cases. 9  Chest pain or pressure Early Renal Insufficiency. It is estimated that as many as 12 million U.S. residents have early renal disease (also called kidney disease) and may go on to develop renal failure.  a syndrome in which all kidney functions are impaired; it results in disturbance of water, electrolyte, and nitrogen metabolism. Renal insufficiency may be acute or chronic. Acute renal insufficiency may be caused by shock resulting from trauma, burns, blood transfusions, or surgery.  This topic provides information about sudden kidney injury. If you are looking for information about long-term kidney disease, see the topic Chronic Kidney Disease. Acute kidney injury (also called acute renal failure) means that your kidneys have suddenly stopped working.
