Kidney failure

Depending on the cause of kidney failure, the early stages may be slowed down or improved by treating the underlying cause. Changing your diet can ease the strain on your kidneys. For example, you may want to consider reducing your intake of protein and phosphate. Foods that are rich in protein include eggs, meat and milk. The body needs some proteins to keep healthy but a GP or nutritionist can advise on the amount that should be eaten. Foods such as muesli, and some seafood and cheeses, are rich in phosphate. It is extremely difficult to cut out all phosphates, so medicines called phosphate binders may be prescribed to prevent this mineral from being absorbed into the blood.

Kidney Diseases

There are several types of problems that may occur to the kidney or bladder. Glomerulonephritis occurs when the minute filtering units of the kidney become swollen and inflamed. There are 2 forms of glomerulonephritis that affect children. Cystitis is infection of the bladder, and pyelonephritis is an infection of the kidney. Pyelonephritis can be chronic or acute. A kidney infection is often serious, requiring hospitalization. Bright's disease involves nephritis, a chronic inflammation of the kidneys, and it is characterized by blood/protein in the urine with associated hypertension and edema. The kidney can not properly excrete salt and other wastes, resulting in retention of salt and water (edema). When the bloodstream becomes toxic with wastes due to kidney malfunction, uremia develops.

Renal Cell Cancer
The kidneys are a pair of organs located just above the waist on either side of the backbone. Their job is to filter excess water and waste products from the blood. The water and waste drain from each kidney through a tube called a ureter to the bladder and are eliminated from the body as urine. The kidneys also produce substances that help control blood pressure and formation of red blood cells. Several different types of cancer can develop in the kidney. Conventional or clear cell renal cell cancer, also known as renal cell carcinoma, is by far the most common type of kidney cancer in adults. Renes is the Latin word for kidney. Renal cell carcinoma accounts for about 85% of cancers arising from the kidney. Renal cell carcinoma develops in the tubules of the kidney, part of the filtering system.

Kidney Transplant
A kidney transplant is used to treat kidney failure, a condition in which your kidneys can function at only a fraction of normal capacity. People with end-stage kidney disease need either artificial blood filtering (dialysis) or a kidney transplant to stay alive.

Kidney infection
Kidney infection typically occurs when bacteria enter your urinary tract through the urethra and begin to multiply. Bacteria from an infection elsewhere in your body also can spread through your bloodstream to your kidneys. Kidney infection is unusual through this route, but it can occur in some circumstances for instance, when a foreign body, such as an artificial joint or heart valve, gets infected. Rarely, kidney infection results after kidney surgery.

Renal Colic
Renal colic is a pain that is commonly caused by kidney stones. The word "renal" refers to anything related to the kidneys. Renal colic pain is in your lower back, usually on one side. The pain may also be felt in the belly or genitals (testicles or vagina). The pain may come and go and can be very bad. Kidney stones are rock-like pieces that can be as small as a grain of sand, but they also may be larger. These stones form in the kidneys and usually get stuck in one of the two ureters (u-RE-ters). Ureters are the flexible tubes that go from your kidneys to your bladder. Blood clots, dead tissue or other materials may also cause renal colic. You may also see blood in your urine or it can hurt when you urinate. You may feel sick to your stomach (nausea) or vomit (throw up).

Renal scan
A renal scan is a nuclear medicine exam in which a small amount of radioactive material (radioisotope) is used to measure the function of the kidneys.

End-Stage Renal Disease
Healthy kidneys clean your blood by removing excess fluid, minerals and wastes. They also make hormones that keep your bones strong and your blood healthy. But if the kidneys are damaged, they don't work properly. Harmful wastes can build up in your body. Your blood pressure may rise. Your body may retain excess fluid and not make enough red blood cells. This is called kidney failure. If your kidneys fail, you need treatment to replace the work they normally do. The treatment options are dialysis or a kidney transplant. Each treatment has benefits and drawbacks. No matter which treatment you choose, you'll need to make some changes in your life, including how you eat and plan your activities. But with the help of healthcare providers, family and friends, most people with kidney failure can lead full and active lives.

Kidney cancer
You have two kidneys. They are fist-sized organs on either side of your backbone above your waist. The tubes inside filter and clean your blood, taking out waste products and making urine. Kidney cancer forms in the lining of tiny tubes inside your kidneys. It happens most often in people over 40. Risk factors include smoking, having certain genetic conditions and misusing pain medicines for a long time. Often, kidney cancer doesn't have early symptoms. However, see your health care provider if you notice

Renal Dialysis
When your kidneys are healthy, they clean your blood. They also make hormones that keep your bones strong and your blood healthy. When your kidneys fail, you need treatment to replace the work your kidneys used to do. Unless you have a kidney transplant, you will need a treatment called dialysis. There are two main types of dialysis: hemodialysis and peritoneal dialysis. Both types filter your blood to rid your body of harmful wastes, extra salt and water. Hemodialysis does that with a machine. Peritoneal dialysis uses the lining of your abdomen, called the peritoneal membrane, to filter your blood. Each type has both risks and benefits. They also require that you follow a special diet. Your doctor can help you decide the best type of dialysis for you.

Polycystic kidney disease
Your kidneys are two bean-shaped organs, each about the size of your fists. They are located near the middle of your back, just below the rib cage. Inside each kidney about a million tiny structures called nephrons filter blood. They remove waste products and extra water, which become urine. The urine flows through tubes called ureters to your bladder, which stores the urine until you go to the bathroom. Damage to the nephrons results in kidney disease. This damage may leave kidneys unable to remove wastes. Usually the damage occurs slowly over years. There are no obvious symptoms, so you don't know it is happening.

Renal biopsy
A renal biopsy is the removal of a small piece of kidney tissue for laboratory examination.

Renal venogram
A renal venogram is a test to look at the veins in the kidney. It uses x-rays and a special dye (called contrast). X-rays are a form of electromagnetic radiation like light, but of higher energy, so they can move through the body to form an image on film. Structures that are dense (such as bone) will appear white, air will be black, and other structures will be shades of gray. Veins are not normally seen in an x-ray. That is why the special dye is needed. The dye highlights the veins so they show up better on x-rays. See also: Renal arteriography
