(From Wikipedia, the free Encyclopedia)
The kidneys are the most important excretory organ in vertebrates. Medical terms related to the kidneys either involve renal or nephro-. Nephrology is the study of the kidneys.In a normal human adult, each kidney is about 11 cm long and about 5 cm thick, weighing 150 grams. The kidneys are 'bean-shaped' organs, and have a concave side facing inwards (medially). On this medial aspect of each kidney is an opening, called the hilus, which admits the renal artery, the renal vein, nerves, and the ureter. A kidney is divided into a renal cortex, medulla and pelvis.
Section of a kidney The basic functional unit of the kidney is the nephron, of which there are more than a million in each normal adult kidney. Nephrons regulate water and soluble substances (especially ions) in the body by filtering it all out first, reabsorbing what should be kept and excreting the rest. They use countercurrent exchange mechanisms. A nephron consists of a Bowman's capsule, a proximal convoluted tubule, a loop of Henle and a distal convoluted tubule which empties the urine into a collecting duct.
Terms:
- renal capsule: The membranous covering of the kidney.
- cortex: The outer layer over the internal medulla. It contains blood vessels, glomeruli (which are the kidneys' "filters") and urine tubes and is supported by a fibrous matrix.
- hilus: The opening in the middle of the concave medial border for nerves and blood vessels to pass into the renal sinus.
- renal column: The structures which support the cortex. They consist of lines of blood vessels and urinary tubes and a fibrous material.
- renal sinus: The cavity which houses the renal pyramid.
- calyces: The recesses in the internal medulla which hold the pyramids. They are used to subdivide the sections of the kidney. (singular - calyx)
- papillae: The small conical projections along the wall of the renal sinus. They have openings through which urine passes into the calyces. (singular - papilla)
- pyramids: The conical segments within the internal medulla. They contain the secreting apparatus and tubules and are also called malpighian pyramids.
- renal artery: Two renal arteries come from the aorta, each connecting to a kidney. The artery divides into five branches, each of which leads to a ball of capillaries. The arteries supply (unfiltered) blood to the kidneys. The left kidney receives about 60% of the renal bloodflow.
- renal vein: The filtered blood returns to circulation through the renal veins which join into the inferior vena cava.
- renal pelvis: Basically just a funnel, the renal pelvis accepts the urine and channels it out of the hilus into the ureter.
- ureter: A narrow tube 40 cm long and 4 mm in diameter. Passing from the renal pelvis out of the hilus and down to the bladder. The ureter carries urine from the kidneys to the bladder.
Diseases and disorders
Congenital diseases of the kidneys
- Congenital hydronephrosis
- renal dysplasia
- Congenital obstruction of urinary tract
- horseshoe kidney
- duplicated ureter
Acquired diseases of the kidneys
- Kidney stones are a relatively common and particularly painful disorder.
- Pyelonephritis is infection of the kidneys and is frequently caused by complication of a urinary tract infection.
- Azotemia is a toxic condition characterized by abnormal and dangerously high levels of urea, creatinine, various body waste compounds, and other nitrogen-rich compounds in the blood.
- Hydronephrosis is the enlargement of one or both of the kidneys
- Pyelonephritis
- In nephrotic syndrome, the glomerulus has been damaged so that proteins from the blood can enter the urine
- kidney tumors
- Wilm's tumor
- Renal failure (acute and chronic)
- Glomerulonephritis
- Diabetic nephropathy
- Lupus nephritis
Diagnosis
The basic means to assess excretory function of the kidneys is glomerular filtration rate; usually a creatinine clearance test is performed
Dialysis and kidney transplants
Generally, one can live fine with just one kidney. If both kidneys don't function properly, dialysis is performed, where the blood is filtered outside of the body. Kidney transplants are now also quite common. The first successful such transplant was announced on March 4, 1954 by Peter Bent Brigham Hospital in Boston.

(From Wikipedia, the free Encyclopedia)
Kidney stones are solid accretions (crystals) of dissolved minerals in urine found inside the kidneys. Also known as nephrolithiasis, urolithiasis or renal calculi. They vary in size from as small as a grain of sand to as large as a golf ball. Kidney stones typically leave the body in the urine stream; if they grow relatively large before passing, their jagged crystalline shape can cause severe pain in the ureters and urethra. Because the urethra is longer in males than in females, kidney stones are more likely to be a severe problem for men than for women.Consumption of too much calcium can aggravate the development of kidney stones, since the most common type of stone is calcium oxalate. The calcium renders these stones radio-opaque and they can be detected by an KUB. Other examples of kidney stones include struvite (magnesium, ammonium and phosphate), uric acid, calcium phosphate, or cystine (the amino acid found only in people suffering from cystinuria). There are many types of kidney stone, and a person may be susceptible to only some of them.
Symptoms
Kidney stones are often idiopathic and asymptomatic until they start to move, but symptoms can include acute renal colic, nausea and vomiting, restlessness, dull pain, hematuria, and possibly fever.
Treatment
Treatments include dietary modifications (including the advice to drink plenty of water), medications, and use of a lithotriptor. Surgery is rarely used to remove kidney stones; instead pain management is used while waiting for the stone to pass on its own. However, in severe cases, extracorporeal shock wave lithotripsy, retrograde intrarenal surgery, percutaneous nephrolithotripsy, or open surgery may be necessary.
More Information
Kidney stones are unrelated to gallstones.Isaac Asimov suffered from kidney stones, and wrote about how his pain was treated with morphine, saying that he feared becoming addicted to it if he ever needed it again.
