	Renal vein thrombosis
		In adults, renal vein thrombosis can be caused by injury to the abdomen or back, as a result of malignant kidney tumors growing into the renal vein, or as a result of kidney diseases that cause degenerative changes in the cells of the renal tubules (nephrotic syndrome).
		Renal venography, where a contrast material (dye) is injected into the renal vein before x rays are taken, is one of the best ways to detect renal vein thrombosis.
		Death from renal vein thrombosis is rare, and is often caused by the blood clot detaching and lodging in the heart or lungs.

		Renal vein thrombosis develops when a blood clot forms in the renal vein, which is the blood vessel that carries blood from the kidneys back to the heart.
		In adults, renal vein thrombosis can be caused by injury to the abdomen or back, malignant kidney tumors growing into the renal vein, scar formation (stricture) and other blockages in the vein, or kidney diseases that cause degenerative changes in the cells of the renal tubules (nephrotic syndrome).
		Renal vein thrombosis is more common in patients with nephrotic syndrome, although studies have shown high variability among these patients, with rates of 5 to 62 percent reported.

		They are protected by three layers of connective tissue: the renal fascia (fibrous membrane) surrounds the kidney and binds the organ to the abdominal wall; the adipose capsule (layer of fat) cushions the kidney; and the renal capsule (fibrous sac) surrounds the kidney and protects it from trauma and infection.
		The renal artery enters the kidney and the renal vein emerges from the kidney at an indentation in the middle of the organ called the hilum.

		Renal cell cancer is usually diagnosed with a biopsy.
		In the 60% of patients with renal cell cancer that has spread outside the kidney, the disease is generally not curable with surgery and other specialists, such as medical oncologists and possibly even radiation therapists, are involved with treatment.
		The primary tumor may have spread to the renal veins or vena cava (large vein returning blood to the heart located in the middle of the abdomen near the back), but has only spread directly and not out of the local area of the kidney.

	Renal Vascular Hypertension (Site not responding. Last check: 2007-11-06)
		Atherosclerotic renal artery stenosis tends to involve the origin (proximal 2 cm) and major bifurcations of the renal artery (although medium sized vessel disease within the kidney may be seen).
		In renal artery stenosis, transcapillary pressures to drive glomerular filtration are maintained by a preferential increase in the efferent arteriolar resistance behind the glomerulus.
		When a critical level of renal artery stenosis is reached (about 60-70% of the lumen) baroreceptors in the kidney sense the decreased blood pressure in the afferent arteriole, which results in increased renin release from the juxtaglomerular apparatus.

	Renal Hemodynamics
		Because of the resistance of the intrarenal veins, pressure drops from 20 in peritubular capillaries to 5 mm Hg in the renal vein.
		These clearances are called effective renal plasma flow and are less than the true RPF because (1) plasma flow through renal connective and adipose tissue is not included and (2) incomplete extraction of solutes from rapidly flowing blood in peritubular capillaries precludes total secretion of all the PAH present in the blood perfusing the tubules.
		It is released in response to decreases in renal perfusion pressure (decreased stretch reduce cell calcium which promotes renin release), by sympathetic stimulation through renal nerves and by reduced flow and transport at MD cells (which reduce cell calcium, decrease arachidonic acid release and in turn reduce cell Ca in afferent arterioles).
