Renal excretion is the major organ of the human body. Kidney is the organ-forming urine. The formation of urine done in stages ranging from filtering (filtration), the re-absorption (reabsorption) and secretion. This process occurs in certain parts of the kidney, such as glomerular filtration happening.
Can kidney disorder that can cause problems such as kidney failure until the screening process can not produce urine. Here are the types of diseases that can affect the kidneys.
1. Albuminuria
Albuminuria is a disease that occurs due to the kidneys are not able to do the screening, particularly screening protein. Because of protein (albumin) is not filtered, the protein can be out with urine.
2. Kidney stones
Kidney stones is a disease that occurs because of something that settles in the kidneys or bladder cavity. The precipitate may be formed from a compound of calcium and uric acid buildup. Frequent urinary incontinence and lack of drinking can cause the formation of kidney stones. In addition, kidney stones can also be caused by a metabolic disorder that causes the buildup of uric acid and calcium compounds.
Kidney stones can be treated with certain medications. With the development of technology, kidney stones can be destroyed using a laser beam. Kidney stones will be small flakes which then came out with urine. However, treatment with drugs and laser light only a small kidney stone. Kidney stones can be removed which has been enlarged through surgery.
3. Diabetes mellitus
Diabetes mellitus (diabetes) is a disease caused by low levels of the hormone insulin in the body. Lower insulin levels may interfere with the process of renovation of glucose into glycogen, akibatknya gluosa existing levels in the blood increase. Increases in glucose levels can not be reabsorbed so that glucose will come out along with the urine.
4. Diabetes insipidus
Diabetes insipidus is a disease caused by deficiency of hormones ADH (antidiuretic hormone). ADH hormone is a hormone that serves to facilitate the absorption of water in the vessel distal and collecting vessels. When the water concentration in the blood falls (fluids more concentrated), there will be a secretion of ADH hormone and hormones are supplied with blood. Urine produced will amount to little.
Conversely, if the blood contains a high concentration of water (blood thinner), the hormone ADH is secreted reduced and generated a lot of urine and dilute. In patients with diabetes insipidus, urine volume generated more than normal, even up to 30 times the normal volume of urine. Consequently, urinating often done by people.
5. Nephritis
Nephritis is an infectious disease of the kidneys. The infection can be caused by Streptococcus bacteria that enter through the respiratory tract and then carried by the blood to the kidneys. This infection causes inflammation. Inflammation causes the inability of the kidneys to filter blood cells and proteins that go along with the primary urine. Seain it can also cause inflammation of urea into the blood exceeds normal limits. This condition is called uremia. The presence of urea in the blood can cause impaired absorption of water, then the water will accumulate in the legs or other body parts. This condition is called edema.
6. Renal failure (anuria)
Anuria or renal failure is the failure of the kidneys to make urine. This condition is caused by the glomerulus is damaged. The damage penyebabkan screening process can not be done so that no urine produced. Patients with kidney failure can be treated by using an artificial kidney dialysis process is known. Dialysis using a device called a hemodialysis machine. Another option for patients with renal failure is a kidney transplant. The disadvantage is the difficulty of finding a suitable donor kidney to the patient's body.
That's six types of diseases that can occur in the kidneys.
