Within the kidneys, there are things called nephrons. There are about two million nephrons found in each kidney. The function of the nephrons are to filter blood. They do this by removing excess liquid and waste. There are two main parts of a nephron; the tubule and the glomerulus. Diseases in the glomerulus are called glomerulopathy.

There are two main types of glumerulopathy (or glumerul disease): Glumerulonephritis or Glomerulosclerosis. 

Glumerulonephritis 

Glumerulonephritis is when there is inflammation or damage in the tiny filters (glomeruli) of the kidneys. It is caused by problems with the immune system. When you have glumerulonephritis your kidneys will have trouble removing waste and fluid from your body. It occurs on its own or an result of another disease, like lupus or diabetes. If this condition becomes severe, kidney failure is a possibility.

Treatment may vary based off of the type of Glumerulonephritis you have developed.

There are two types of Glumerulonephritis. 

Acute Glumerulonephritis

Acute Glumerulonephritis is a sudden developement of Glumerulonephritis. It can be from a primary renal cause or a secondary cause, such as a viral infection.

Chronic Glumerulonephritis

Chronic Glumerulonephritis is formed over time. Mainly, through conditions such as high blood pressure. This is the more common type of Glumerulonephritis.

Glomerulosclerosis

Glomerulosclerosis is the scarring of the filtering parts of the kidneys (glomeruli). This causes excess protein to be found in the blood. The scarring disrupts the filtration process, resulting in fluid buildup in other parts of the body.

Scarred glomeruli cannot be repaired. Treatment can only prevent further damage and attempt to circumvent the need for dialysis. The best treatment solely depends on the on the reason for it. 

Regardless of treatment, your kidney disease can progress on to kidney failure, which will ultimately result in the need for dialysis and/or a kidney transplant.
