What is (are) Solitary Kidney ? 

When a person has only one kidney or one working kidney, this kidney is called a solitary kidney. The three main causes of a solitary kidney are
                
- birth defects. People with kidney agenesis are born with only one kidney. People born with kidney dysplasia have both kidneys; however, one kidney does not function. Many people with kidney agenesis or kidney dysplasia do not discover that they have a solitary kidney until they have an x ray, an ultrasound, or surgery for an unrelated condition.  - surgical removal of a kidney. Some people must have a kidney removed to treat cancer or another disease or injury. When a kidney is removed surgically due to disease or for donation, both the kidney and ureter are removed.  - kidney donation. A growing number of people are donating a kidney to be transplanted into a family member or friend whose kidneys have failed.
                
In general, people with a solitary kidney lead full, healthy lives. However, some people are more likely to develop kidney disease.
What is (are) Solitary Kidney ? 

The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Every day, the kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra fluid. The urine flows from the kidneys to the bladder through tubes called ureters. The bladder stores urine until releasing it through urination.
What to do for Solitary Kidney ? 

People with a solitary kidney do not need to eat a special diet. However, people with reduced kidney function may need to make changes to their diet to slow the progression of kidney disease. More information about recommended dietary changes is provided in the NIDDK health topics, Nutrition for Early Chronic Kidney Disease in Adults and Nutrition for Advanced Chronic Kidney Disease in Adults, and on the National Kidney Disease Education Program website. People should talk with their health care provider about what diet is right for them.
                
Controlling Blood Pressure
                
People can control their blood pressure by not smoking, eating a healthy diet, and taking certain medications. Medications that lower blood pressure can also significantly slow the progression of kidney disease. Two types of blood pressurelowering medications, angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), have proven effective in slowing the progression of kidney disease. Many people require two or more medications to control their blood pressure. In addition to an ACE inhibitor or ARB, a diuretica medication that helps the kidneys remove fluid from the bloodmay be prescribed. Beta-blockers, calcium channel blockers, and other blood pressure medications may also be needed.
                
Preventing Injury
                
For people with a solitary kidney, loss of the remaining working kidney results in the need for dialysis or kidney transplant. People should make sure their health care providers know they have a solitary kidney to prevent injury from medications or medical procedures. People who participate in certain sports may be more likely to injure the kidney; this risk is of particular concern with children, as they are more likely to play sports. The American Academy of Pediatrics recommends individual assessment for contact, collision, and limited-contact sports. Protective equipment may reduce the chance of injury to the remaining kidney enough to allow participation in most sports, provided that such equipment remains in place during activity. Health care providers, parents, and patients should consider the risks of any activity and decide whether the benefits outweigh those risks.

What is (are) Overview of Kidney Disease in Children ? 

The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Every day, the two kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra fluid. Children produce less urine than adults and the amount produced depends on their age. The kidneys work around the clock; a person does not control what they do. Ureters are the thin tubes of muscleone on each side of the bladderthat carry urine from each of the kidneys to the bladder. The bladder stores urine until the person finds an appropriate time and place to urinate.
                
The kidney is not one large filter. Each kidney is made up of about a million filtering units called nephrons. Each nephron filters a small amount of blood. The nephron includes a filter, called a glomerulus, and a tubule. The nephrons work through a two-step process. The glomerulus lets fluid and waste products pass through it; however, it prevents blood cells and large molecules, mostly proteins, from passing. The filtered fluid then passes through the tubule, which changes the fluid by sending needed minerals back to the bloodstream and removing wastes. The final product becomes urine.
                
The kidneys also control the level of minerals such as sodium, phosphorus, and potassium in the body, and produce an important hormone to prevent anemia. Anemia is a condition in which the number of red blood cells is less than normal, resulting in less oxygen carried to the bodys cells.
How to diagnose Overview of Kidney Disease in Children ? 

A health care provider diagnoses kidney disease in children by completing a physical exam, asking for a medical history, and reviewing signs and symptoms. To confirm diagnosis, the health care provider may order one or more of the following tests:
                
Urine Tests
                
Dipstick test for albumin. The presence of albumin in urine is a sign that the kidneys may be damaged. Albumin in urine can be detected with a dipstick test performed on a urine sample. The urine sample is collected in a special container in a health care providers office or a commercial facility and can be tested in the same location or sent to a lab for analysis. With a dipstick test, a nurse or technician places a strip of chemically treated paper, called a dipstick, into the persons urine sample. Patches on the dipstick change color when albumin is present in urine.
                
Urine albumin-to-creatinine ratio. A more precise measurement, such as a urine albumin-to-creatinine ratio, may be necessary to confirm kidney disease. Unlike a dipstick test for albumin, a urine albumin-to-creatinine ratiothe ratio between the amount of albumin and the amount of creatinine in urineis not affected by variation in urine concentration.
                
Blood test. Blood drawn in a health care providers office and sent to a lab for analysis can be tested to estimate how much blood the kidneys filter each minute, called the estimated glomerular filtration rate or eGFR.
                
Imaging studies. Imaging studies provide pictures of the kidneys. The pictures help the health care provider see the size and shape of the kidneys and identify any abnormalities.
                
Kidney biopsy. Kidney biopsy is a procedure that involves taking a small piece of kidney tissue for examination with a microscope. Biopsy results show the cause of the kidney disease and extent of damage to the kidneys.
What to do for Overview of Kidney Disease in Children ? 

- Kidney disease can affect children in various ways, ranging from treatable disorders without long-term consequences to life-threatening conditions. Acute kidney disease develops suddenly, lasts a short time, and can be serious with long-lasting consequences, or may go away completely once the underlying cause has been treated.  - Chronic kidney disease (CKD) does not go away with treatment and tends to get worse over time.  - Kidney disease in children can be caused by      - birth defects    - hereditary diseases    - infection    - nephrotic syndrome    - systemic diseases    - trauma    - urine blockage or reflux    - A health care provider diagnoses kidney disease in children by completing a physical exam, asking for a medical history, and reviewing signs and symptoms. To confirm diagnosis, the health care provider may order one or more of the following tests:      - urine tests    - blood test    - imaging studies    - kidney biopsy    - Treatment for kidney disease in children depends on the cause of the illness.  - Children with a kidney disease that is causing high blood pressure may need to take medications to lower their blood pressure. Improving blood pressure can significantly slow the progression of kidney disease. As kidney function declines, children may need treatment for anemia and growth failure.  - Children with kidney disease that leads to kidney failure must receive treatment to replace the work the kidneys do. The two types of treatment are dialysis and transplantation.  - For children with CKD, learning about nutrition is vital because their diet can affect how well their kidneys work. Parents or guardians should always consult with their childs health care team before making any dietary changes.
What is (are) Graves' Disease ? 

Graves disease, also known as toxic diffuse goiter, is the most common cause of hyperthyroidism in the United States. Hyperthyroidism is a disorder that occurs when the thyroid gland makes more thyroid hormone than the body needs.
                
The Thyroid
                
The thyroid is a 2-inch-long, butterfly-shaped gland in the front of the neck below the larynx, or voice box. The thyroid makes two thyroid hormones, triiodothyronine (T3 ) and thyroxine (T4 ). T3 is made from T4 and is the more active hormone, directly affecting the tissues. Thyroid hormones circulate throughout the body in the bloodstream and act on virtually every tissue and cell in the body.
                
Thyroid hormones affect metabolism, brain development, breathing, heart and nervous system functions, body temperature, muscle strength, skin dryness, menstrual cycles, weight, and cholesterol levels. Hyperthyroidism causes many of the bodys functions to speed up.
                
Thyroid hormone production is regulated by another hormone called thyroid-stimulating hormone (TSH), which is made by the pituitary gland in the brain. When thyroid hormone levels in the blood are low, the pituitary releases more TSH. When thyroid hormone levels are high, the pituitary responds by decreasing TSH production.
                

                
Autoimmune Disorder
                
Graves disease is an autoimmune disorder. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. But in autoimmune diseases, the immune system attacks the bodys own cells and organs.
                
With Graves disease, the immune system makes an antibody called thyroid-stimulating immunoglobulin (TSI)sometimes called TSH receptor antibodythat attaches to thyroid cells. TSI mimics TSH and stimulates the thyroid to make too much thyroid hormone. Sometimes the TSI antibody instead blocks thyroid hormone production, leading to conflicting symptoms that may make correct diagnosis more difficult.
What are the symptoms of Graves' Disease ? 

People with Graves disease may have common symptoms of hyperthyroidism such as
                
- nervousness or irritability  - fatigue or muscle weakness  - heat intolerance  - trouble sleeping  - hand tremors  - rapid and irregular heartbeat  - frequent bowel movements or diarrhea  - weight loss  - goiter, which is an enlarged thyroid that may cause the neck to look swollen and can interfere with normal breathing and swallowing
                
A small number of people with Graves disease also experience thickening and reddening of the skin on their shins. This usually painless problem is called pretibial myxedema or Graves dermopathy.
                
In addition, the eyes of people with Graves disease may appear enlarged because their eyelids are retractedseem pulled back into the eye socketsand their eyes bulge out from the eye sockets. This condition is called Graves ophthalmopathy (GO).
What is (are) Graves' Disease ? 

Graves ophthalmopathy is a condition associated with Graves disease that occurs when cells from the immune system attack the muscles and other tissues around the eyes.
                
The result is inflammation and a buildup of tissue and fat behind the eye socket, causing the eyeballs to bulge out. Rarely, inflammation is severe enough to compress the optic nerve that leads to the eye, causing vision loss.
                
Other GO symptoms are
                
- dry, gritty, and irritated eyes  - puffy eyelids  - double vision  - light sensitivity  - pressure or pain in the eyes  - trouble moving the eyes
                
About 25 to 30 percent of people with Graves disease develop mild GO, and 2 to 5 percent develop severe GO.1 This eye condition usually lasts 1 to 2 years and often improves on its own.
                
GO can occur before, at the same time as, or after other symptoms of hyperthyroidism develop and may even occur in people whose thyroid function is normal. Smoking makes GO worse.

How to diagnose Graves' Disease ? 

Health care providers can sometimes diagnose Graves disease based only on a physical examination and a medical history. Blood tests and other diagnostic tests, such as the following, then confirm the diagnosis.
                
TSH test. The ultrasensitive TSH test is usually the first test performed. This test detects even tiny amounts of TSH in the blood and is the most accurate measure of thyroid activity available.
                
T3 and T4 test. Another blood test used to diagnose Graves disease measures T3 and T4 levels. In making a diagnosis, health care providers look for below-normal levels of TSH, normal to elevated levels of T4, and elevated levels of T3.
                
Because the combination of low TSH and high T3 and T4 can occur with other thyroid problems, health care providers may order other tests to finalize the diagnosis. The following two tests use small, safe doses of radioactive iodine because the thyroid uses iodine to make thyroid hormone.
                
Radioactive iodine uptake test. This test measures the amount of iodine the thyroid collects from the bloodstream. High levels of iodine uptake can indicate Graves disease.
                
Thyroid scan. This scan shows how and where iodine is distributed in the thyroid. With Graves disease the entire thyroid is involved, so the iodine shows up throughout the gland. Other causes of hyperthyroidism such as nodulessmall lumps in the glandshow a different pattern of iodine distribution.
                
TSI test. Health care providers may also recommend the TSI test, although this test usually isnt necessary to diagnose Graves disease. This test, also called a TSH antibody test, measures the level of TSI in the blood. Most people with Graves disease have this antibody, but people whose hyperthyroidism is caused by other conditions do not.
                
More information about testing for thyroid problems is provided in the NIDDK health topic, Thyroid Tests.
What are the treatments for Graves' Disease ? 

Treatment for Graves disease can sometimes affect pregnancy. After treatment with surgery or radioactive iodine, TSI antibodies can still be present in the blood, even when thyroid levels are normal. If a pregnant woman has received either of these treatments prior to becoming pregnant, the antibodies she produces may travel across the placenta to the babys bloodstream and stimulate the fetal thyroid.
                
A pregnant woman who has been treated with surgery or radioactive iodine should inform her health care provider so her baby can be monitored for thyroid-related problems later in the pregnancy. Pregnant women may safely be treated with anti-thyroid medications.
                
For more information about pregnancy and anti-thyroid medications, see Medications under the section titled How is Graves disease treated?More information about pregnancy and thyroid disease is provided in the NIDDK health topic, Pregnancy and Thyroid Disease.
What to do for Graves' Disease ? 

Experts recommend that people eat a balanced diet to obtain most nutrients. More information about diet and nutrition is provided by the National Agricultural Library available at www.nutrition.gov.
                
Dietary Supplements
                
Iodine is an essential mineral for the thyroid. However, people with autoimmune thyroid disease may be sensitive to harmful side effects from iodine. Taking iodine drops or eating foods containing large amounts of iodinesuch as seaweed, dulse, or kelpmay cause or worsen hyperthyroidism. More information about iodine is provided by the National Library of Medicine in the fact sheet, Iodine in diet, available at www.nlm.nih.gov/medlineplus.
                
Women need more iodine when they are pregnantabout 250 micrograms a daybecause the baby gets iodine from the mothers diet. In the United States, about 7 percent of pregnant women may not get enough iodine in their diet or through prenatal vitamins.3 Choosing iodized saltsalt supplemented with iodineover plain salt and prenatal vitamins containing iodine will ensure this need is met.
                
To help ensure coordinated and safe care, people should discuss their use of dietary supplements, such as iodine, with their health care provider. Tips for talking with health care providers are available through the National Center for Complementary and Integrative Health.

What is (are) Diabetic Kidney Disease ? 

Diabetic kidney disease, also called diabetic nephropathy, is kidney disease caused by diabetes. Even when well controlled, diabetes can lead to chronic kidney disease (CKD) and kidney failure, described as end-stage kidney disease or ESRD when treated with a kidney transplant or blood-filtering treatments called dialysis.
                
Diabetes affects 25.8 million people of all ages in the United States.1 As many as 40 percent of people who have diabetes are expected to develop CKD.2 Diabetes, the most common cause of kidney failure in the United States, accounts for nearly 44 percent of new cases of kidney failure, as illustrated in Figure 1.3
What is (are) Diabetic Kidney Disease ? 

The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Every day, the two kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra fluid. The urine flows from the kidneys to the bladder through tubes called ureters. The bladder stores urine.
                
When the bladder empties, urine flows out of the body through a tube called the urethra, located at the bottom of the bladder. In men the urethra is long, while in women it is short.
                
Kidneys work at the microscopic level. The kidney is not one large filter. Each kidney is made up of about a million filtering units called nephrons. Each nephron filters a small amount of blood. The nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process.

What is (are) Diabetic Kidney Disease ? 

Diabetes is a complex group of diseases with a variety of causes. People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia.
                
Diabetes is a disorder of metabolism the way the body uses digested food for energy. The digestive tract breaks down carbohydratessugars and starches found in many foodsinto glucose, a form of sugar that enters the bloodstream. With the help of the hormone insulin, cells throughout the body absorb glucose and use it for energy.
                
Insulin is made in the pancreas, an organ located behind the stomach and below the liver. As blood glucose levels rise after a meal, the pancreas is triggered to release insulin. The pancreas contains clusters of cells called pancreatic islets. Beta cells within the pancreatic islets make insulin and release it into the blood.
                
Diabetes develops when the body doesnt make enough insulin, is not able to use insulin effectively, or both. As a result, glucose builds up in the blood instead of being absorbed by cells in the body. The bodys cells are then starved of energy despite high blood glucose levels.
What are the symptoms of Diabetic Kidney Disease ? 

People with diabetic kidney disease do not have symptoms in the early stages. As kidney disease progresses, a person can develop edema, or swelling. Edema happens when the kidneys cannot get rid of the extra fluid and salt in the body. Edema can occur in the legs, feet, or ankles and less often in the hands or face. Once kidney function decreases further, symptoms may include
                
- appetite loss  - nausea  - vomiting  - drowsiness, or feeling tired  - trouble concentrating  - sleep problems  - increased or decreased urination  - generalized itching or numbness  - dry skin  - headaches  - weight loss  - darkened skin  - muscle cramps  - shortness of breath  - chest pain
