	Dr. Koop - Renal artery stenosis
		Renal artery stenosis is caused when atheroembolic renal disease results in narrowing of the renal artery.
		Renal artery stenosis often causes hypertension (high blood pressure)Â with no other signs of its presence, and it is usually discovered in investigation for the cause of hypertension that is difficult to control.
		Renal artery stenosis is, in fact, among the most common causes of secondary (caused by another condition)Â hypertension.

		Renal artery stenosis is a narrowing or blockage of the artery that supplies the kidney, caused by atherosclerosis, fibromuscular dysplasia of the renal artery wall, or scar formation in the artery.
		Renal artery stenosis often causes hypertension with no other signs of its presence, and it is usually discovered in investigation for the cause of hypertension that is difficult to control.
		Renal artery stenosis may cause chronic renal failure if it affects both renal arteries or if the hypertension associated with this condition is prolonged or severe.

		The arterial supply of the kidneys is variable and there may be one or more renal arteries supplying each kidney.
		The renal arteries carry a large portion of total blood flow to the kidneys.
		Atherosclerosis (A stage of arteriosclerosis involving fatty deposits (atheromas) inside the arterial walls) can also affect the renal arteries and can lead to poor perfusion of the kidneys leading to reduced kidney function and, possibly, renal failure (Inability of the kidneys to excrete wastes and to help maintain the electrolyte balance).

	Renal Osteodystrophy (Site not responding. Last check: 2007-11-03)
		The etiology of renal osteodystrophy is incompletely understood.
		Elevated PTH levels are sustained by decreased renal degradation and reduced negative feedback suppression by vitamin D. PTH acts to raise calcium by osteoclast activation, stimulation of intestinal absorption and various renal effects.
		The clinical presentation is influenced by the patient's age at onset of renal failure, the etiology of the renal disease, dietary content (protein, phosphate and calcium) and treatment modalities.

	Renal artery stenosis
		Renal artery stenosis is a blockage or narrowing of the major arteries that supply blood to the kidneys.
		Renal artery stenosis occurs when the flow of blood from the arteries leading to the kidneys is constricted by tissue or artherosclerotic plaque.
		Renal artery stenosis is a serious and potentially life-threatening condition, and should always be treated by a healthcare professional familiar with the disorder.

	Renal artery occlusion
		Renal artery occlusion is a blockage of the major arteries that supply blood to the kidneys caused by thrombosis or embolism.
		Renal artery occlusion occurs when the flow of blood from the arteries leading to the kidneys becomes blocked by a blood clot or cholesterol emboli.
		Renal arterial occlusion occurs when a thrombus or embolism (blood clot or cholesterol plaque) breaks free and blocks the arteries leading to one or both kidneys.

		Reduction of the glomerular perfusion pressure behind a stenosis of the renal artery induces dilatation of the afferent arteriole and constriction of the efferent arteriole.
		The decreased resistance of the afferent arteriole is mediated by vasodilatory prostaglandins, the constriction of the efferent vessel by angiotensin II.

		Renal artery stenosis (narrowing) is a decrease in the diameter (width) of the artery supplying blood to the kidney.
		Renovascular hypertension occurs when the artery to one of the kidneys is narrowed (unilateral stenosis), while renal failure occurs when the arteries to both kidneys are narrowed (bilateral stenosis).
		As a matter of fact, as many as 15% of older patients with progressive renal failure may have unsuspected bilateral (both kidneys) renal artery stenosis as the cause of their renal failure.

	Renal artery stenosis
		A kidney X-ray, kidney CT scan, or kidney ultrasound may indicate a decreased size of the kidney, and/or a decreased arterial flow secondary to narrowing of the artery.
		A balloon angioplasty (a radiographic procedure during which a balloon-tipped catheter is threaded through the artery) or a stent placement across the stenosis may be an alternative to surgery to open the stenosed area.

		Atherosclerosis, or “hardening of the arteries”, may affect and impair blood flow to the kidneys. This may result in impaired kidney function as well as progressive and severe high blood pressure.
		Any patient with impaired renal function and severe hypertension should be evaluated for renal artery arterial occlusive disease.
		When renal functional impairment is advanced and hypertensive control has proven difficult, treatment of renal artery narrowing is indicated.

		Acute arterial occlusion of the kidney may occur after injury or trauma to the abdomen, side, or occasionally the back.
		Occasionally, renal artery stenosis or atheroembolic renal disease (the effects of atherosclerosis on the kidney) may predispose individuals to a sudden thrombosis (clot) of the renal artery.

	Explosive growth in renal artery interventional procedures; More cardiologists performing procedures
		The annual number of Medicare beneficiaries who underwent renal artery interventional procedures to unblock arteries more than doubled between 1996 and 2000, with much of the growth attributed to more cardiologists beginning to do these procedures, according to a new study.
		The greatest increase in the use of renal artery interventions occurred in the southeast (Alabama, Kentucky, Mississippi, North Carolina, South Carolina and Tennessee) with an increase from 22 per 100,000 Medicare beneficiaries in 1996 to 86 per 100,000 beneficiaries in 2000.
		"Blockages in the renal arteries is common, seen in 6-18% of patients undergoing coronary arteriography and in 16-40% of those patients undergoing aortography for aneurysms or peripheral vascular disease," Dr. Murphy said.
