The adrenal glands, located on the top of each kidney, are responsible for releasing different classes of hormones. Malignant and benign tumors can form in the adrenal glands, and may require surgical removal of one or both glands.
Polycystic kidney disease is a genetic disorder that causes numerous cysts to grow in the kidneys. A kidney cyst is an abnormal sac filled with fluid. PKD cysts can greatly enlarge the kidneys while replacing much of their normal structure, resulting in chronic kidney disease (CKD), which causes reduced kidney function over time. CKD may lead to kidney failure, described as end-stage kidney disease or ESRD when treated with a kidney transplant or blood-filtering treatments called dialysis. PKD cysts are different from the usually harmless “simple” cysts that often form in the kidneys later in life. PKD cysts are more numerous and cause complications, such as high blood pressure, cysts in the liver, and problems with blood vessels in the brain and heart. Polycystic kidney disease (PKD) runs in families. In PKD, the cysts take the place of the normal tissue. They enlarge the kidneys and make them work poorly, leading to kidney failure. When PKD causes kidneys to fail - which usually happens after many years - people need dialysis or kidney transplantation. About half of people with the most common type of PKD end up with kidney failure. PKD also causes cysts in other parts of the body, such as the liver. Symptoms of PKD include Pain in the back and lower sides Headaches Urinary tract infections Blood in the urine Doctors diagnose PKD with imaging tests and family history. Treatments include medications, and, when people with PKD develop kidney failure, dialysis or kidney transplants.
Glomerulonephritis may be caused by problems with the body's immune system. Often, the exact cause of this condition is unknown. Damage to the glomeruli causes blood and protein to be lost in the urine. The condition may develop quickly, and kidney function is lost within weeks or months. This is called rapidly progressive glomerulonephritis. A quarter of people with chronic glomerulonephritis have no history of kidney disease
Proteins in the blood also perform a number of important functions. They protect the body from infection, help blood clot, and keep the right amount of fluid circulating throughout the body. As blood passes through healthy kidneys, they filter out the waste products and leave in the things the body needs, like albumin and other proteins. Most proteins are too big to pass through the kidneys' filters into the urine. However, proteins from the blood can leak into the urine when the filters of the kidney, called glomeruli, are damaged. Proteinuria is a sign of chronic kidney disease (CKD), which can result from diabetes, high blood pressure, and diseases that cause inflammation in the kidneys. For this reason, testing for albumin in the urine is part of a routine medical assessment for everyone. Kidney disease is sometimes called renal disease. If CKD progresses, it can lead to end-stage renal disease (ESRD), when the kidneys fail completely. A person with ESRD must receive a kidney transplant or regular blood-cleansing treatments called dialysis.
