Natural human body on the kidneys weigh each one about 150 g, and ranging in length in normal adult between 11-13 cm and a diameter of 4-5 cm, a kidney shape.
The kidneys are located in the abdominal cavity on either side of the spine, at the level of the lumbar spine (from the first until the third), each consisting College
Of about renal million units (nephrons) and each nephron consists of a glomerulus and pipes nomination.
Most important functions of the kidney
O operation begins the nomination and that the passage of blood through the glomeruli, which allow the passage of fluids and salts from which the candidate tubes that absorb salts and liquids rates balanced according to the need of the body, secrete fluids and salts that the body does not need through the urine, which consists of these fluids and salts and other secretions.
2. Control your blood pressure:
The kidneys of the most important control points in blood pressure, when low blood pressure for one reason or another, kidney hormone renin H Rennin which activates a set of chemical reactions produce, and eventually leads to constriction of peripheral arteries, increasing blood pumped from the heart, leading to high blood pressure, and vice versa, when blood pressure rises above normal, the kidneys secrete certain substances, which lead to energizes the peripheral arteries and then widen, to accommodate a larger amount of blood leads to low pressure.
3. regulate the production of red blood cells rate:
Due to the need for kidneys to large amounts of oxygen to perform its functions, as the cells are among the most body cells sensitive to a lack of blood supply (oxygen, nutrition), whereupon the capillaries renal sort hormone EPO, which activates the bone marrow cells helps to quickly multiply and mature productive more than RBCs number RBCs
4. activated vitamin D (Vitamin D):
Vitamin D is responsible for regulating the absorption of calcium from the intestine and deposited in the bones, excess and directed him through the kidneys, etc., and the main source of vitamin D is the self-production of fat under the skin effect of direct sunlight, in addition to dietary sources of animal Kaldhun, the most famous cod liver oil.
5. Adjust the pH of the blood PH:
Where the kidneys secrete excess acid ions such as hydrogen and the development of alkaline carbonate Na Hco3 and add them to the blood.
kidney stones -
Pebble college begins size of a grain of sand from the solid material in college and stick to them or deposited minerals from urine (such as calcium and uric acid salts)
Kidney stones composed of calcium and uric acid or cysteine or methionine. And the most common calcium.
It affects more men than women.
Usually expels liquid waste resulting from the body to the outside through the urine, which consists in the kidneys, but when it is saturated with urine different chemical substances, these materials may crystallize and form deposits similar to gravel in the kidneys.
It consists kidney stones in various sizes, it takes the form of small pebbles can descend down the urinary tract and expel simply through the urine, may take the form of large stones tend to stay within the college, or even as much sometimes to the ureter and settle in it, causing pain severely, and constitute half the people injured kidney stones and other stones within seven years.
When formed renal kidney stone:
College stones are formed more frequently in men and in the prime of middle age, and have Ochks living in a hot climate
A greater chance of developing stones in college if they did not drink enough fluids to compensate for water lost through sweating, there are some individuals who have a genetic predisposition to injury in this case.
Signs and symptoms :
It may not cause any symptoms of small pebbles at all, either large gravel is very painful, it is usually because they pay the ureter to cramping sharply, and this is known as "renal colic" The symptoms are as follows: -
- Severe pain radiating from the back (usually from one side only) to the groin (inguinal) Groin, and sometimes it feels like the genitals as well.
- Urinate frequently and painfully.
- Blood in the urine.
- Nausea and vomiting.
Prevention of college stones: -

1. acute inflammation of the kidneys and bladder:
It is a high presence of pus or microbe by up to urinary tract through the blood Ouan through the reproductive tract and is common among children or adults who suffer from the disease within the tonsils or throat or weakness of the immune system and is treated with antibiotics after the farm work.
2. The presence of salts, kidney or bladder:
A presence proportion of the salts that the body can not get rid of them, such as salts of urate or Alaakslat a small crystals stick to the wall of the kidney and ureter and cause severe pain to the patient or renal colic and treated frequently drink liquids with special types of sparkling or give the patient the solution intravenously to increase the composition of urine and wash the salts with some painkillers.
3. The presence of kidney stones or ureter or bladder:
Gallstone consisting of salts deposited on the wall of the kidney or ureter or bladder and range in size from a pinhead even a golf ball and cause
Many problems such as renal colic or blockage of the ureter and kidney hypertrophy and renal atrophy and being treated by atomizing shock wave laser if it were small and in the nearby Balhalb or by surgery which is the best way because it allows the surgeon to eradicate
