Kidney Cyst: From 1 Different Sources
A fluid-filled sac in the kidney. Most kidney cysts are noncancerous. Cysts commonly develop in people over 50 and may occur singly or multiply in 1 or both kidneys. Most cysts occur for no known reason and do not usually produce symptoms unless they become large enough to cause pain in the lower back due to pressure. However, large numbers of cysts in the kidneys may be associated with polycystic kidney disease (see kidney, polycystic), which often leads to kidney failure. Treatment of simple cysts is not usually necessary, but aspiration (withdrawal of fluid) or surgical removal may be carried out if a cyst is painful or recurs.
Inflammation of a bladder, especially the urinary bladder... cystitis
This is the most common serious genetic disease in Caucasian children, with an incidence of about one per 2,500 births, and more than 6,000 patients in the UK (30,000 in the USA). It is an autosomal recessive disorder of the mucus-secreting glands of the lungs, the pancreas, the mouth, and the gastrointestinal tract, as well as the sweat glands of the skin. The defective gene is sited on chromosome 7 which encodes for a protein, cystic ?brosis transmembrane conductance regulator (CFTR). Individuals who inherit the gene only on one set of chromosomes can, however, carry the defect into successive generations. Where parents have a child with cystic ?brosis, they have a one-infour chance of subsequent children having the disease. They should seek GENETIC COUNSELLING.
The disorder is characterised by failure to gain weight in spite of a good appetite, by repeated attacks of bronchitis (with BRONCHIECTASIS developing at a young age), and by the passage of loose, foul-smelling and slimy stools (faeces). AMNIOCENTESIS, which yields amniotic ?uid along with cells shed from the fetus’s skin, can be used to diagnose cystic ?brosis prenatally. The levels of various enzymes can be measured in the ?uid and are abnormal when the fetus is affected by cystic ?brosis. Neonatal screening is possible using a test on blood spots – immunoreactive trypsin (IRT).
In children with symptoms or a positive family history, the disease can be tested for by measuring sweat chloride and sodium. This detects the abnormal amount of salt that is excreted via the sweat glands when cystic ?brosis is present. Con?rmation is by genetic testing.
Treatment This consists basically of regular physiotherapy and postural drainage, antibiotics and the taking of pancreatic enzyme tablets and vitamins. Some children need STEROID treatment and all require nutritional support. The earlier treatment is started, the better the results. Whereas two decades ago, only 12 per cent of affected children survived beyond adolescence, today 75 per cent survive into adult life, and an increasing number are surviving into their 40s. Patients with end-stage disease can be treated by heart-lung transplantation (with their own heart going to another recipient). Research is underway on the possible use of GENE THERAPY to control the disorder. Parents of children with cystic ?brosis, seeking help and advice, can obtain this from the Cystic Fibrosis Trust.... cystic fibrosis
The surgical excision of the bladder (see URINARY BLADDER). When this is done – usually to treat cancer of the bladder – an alternative means of collecting urine from the KIDNEYS must be arranged. The URETERS of the kidney can be transplanted into a loop of bowel which is brought to the surface of the abdomen to form a STOMA that exits into an externally worn pouch. The latest surgical technique is to fashion a substitute bladder from a section of intestine and to implant the ureters into it, thus allowing the patient to void urine through the urethra as normal.... cystectomy

A fluid-filled lump behind the knee. A Baker’s cyst is caused by increased pressure in the knee joint due to a buildup of fluid in a disorder such as rheumatoid arthritis. Most Baker’s cysts are painless, and some disappear spontaneously. Occasionally, a cyst may rupture, producing pain and swelling in the calf that can mimic a deep vein thrombosis (see thrombosis, deep vein). Diagnosis of a Baker’s cyst is confirmed by ultrasound scanning. Treatment is rarely needed.... baker’s cyst

Hollow tumours (see TUMOUR), containing ?uid or soft material. They are almost always simple in nature.
Retention cysts In these, in consequence of irritation or another cause, some cavity which ought naturally to contain a little ?uid becomes distended, or the natural outlet from the cavity becomes blocked. Wens are caused by the blockage of the outlet from sebaceous glands in the skin, so that an accumulation of fatty matter takes place. RANULA is a clear swelling under the tongue, due to a collection of saliva in consequence of an obstruction to a salivary duct. Cysts in the breasts are, in many cases, the result of blockage in milk ducts, due to in?ammation; they should be assessed to exclude cancer (see BREASTS, DISEASES OF). Cysts also form in the kidney as a result of obstruction to the free out?ow of the urine.
Developmental cysts Of these, the most important are the huge cysts that originate in the OVARIES. The cause is doubtful, but the cyst probably begins at a very early period of life, gradually enlarges, and buds o? smaller cysts from its wall. The contents are usually a clear gelatinous ?uid. Very often both ovaries are affected, and the cysts may slowly reach a great size – often, however, taking a lifetime to do so.
A similar condition sometimes occurs in the KIDNEYS, and the tumour may have reached a great size in an infant even before birth (congenital cystic kidney).
Dermoid cysts are small cavities, which also originate probably early in life, but do not reach any great size until fairly late in life. They appear about parts of the body where clefts occur in the embryo and close up before birth, such as the corner of the eyes, the side of the neck, and the middle line of the body. They contain hair, fatty matter, fragments of bone, scraps of skin, even numerous teeth.
Hydatid cysts are produced in many organs, particularly in the liver, by a parasite which is the larval stage of a tapeworm found in dogs. They occur in people who keep dogs and allow them to contaminate their food. (See TAENIASIS.)... cysts

A pathological rather than a clinical entity. The term refers to the replacement of BONE by a highly cellular and vascular connective tissue. It is the result of osteoclastic and osteoblastic activity and is due to excessive PARATHYROID activity. It is thus seen in a proportion of patients with primary hyperparathyroidism and in patients with uraemic osteodystrophy; that is, the secondary hyperparathyroidism that occurs in patients with chronic renal disease.... osteitis fibrosa cystica
An inherited disease in which the KIDNEYS contain many cysts. These grow in size until normal kidney tissue is largely destroyed. Cysts may also occur in other organs such as the liver. In adults, the disease will cause HYPERTENSION and kidney failure. There is also a juvenile form. There is no e?ective treatment, although symptoms can be alleviated by DIALYSIS and sometimes kidney transplant (see TRANSPLANTATION).... polycystic disease of the kidney
6.5 cm wide, 5 cm thick, and weighs around 140 grams.
Adult kidneys have a smooth exterior, enveloped by a tough ?brous coat that is bound to the kidney only by loose ?brous tissue and by a few blood vessels that pass between it and the kidney. The outer margin of the kidney is convex; the inner is concave with a deep depression, known as the hilum, where the vessels enter. The URETER, which conveys URINE to the URINARY BLADDER, is also joined at this point. The ureter is spread out into an expanded, funnel-like end, known as the pelvis, which further divides up into little funnels known as the calyces. A vertical section through a kidney (see diagram) shows two distinct layers: an outer one, about 4 mm thick, known as the cortex; and an inner one, the medulla, lying closer to the hilum. The medulla consists of around a dozen pyramids arranged side by side, with their base on the cortex and their apex projecting into the calyces of the ureter. The apex of each pyramid is studded with tiny holes, which are the openings of the microscopic uriniferous tubes.
In e?ect, each pyramid, taken together with the portion of cortex lying along its base, is an independent mini-kidney. About 20 small tubes are on the surface of each pyramid; these, if traced up into its substance, repeatedly subdivide so as to form bundles of convoluted tubules, known as medullary rays, passing up towards the cortex. One of these may be traced further back, ending, after a tortuous course, in a small rounded body: the Malpighian corpuscle or glomerulus (see diagram). Each glomerulus and its convoluted tubule is known as a nephron, which constitutes the functional unit of the kidney. Each kidney contains around a million nephrons.
After entering the kidney, the renal artery divides into branches, forming arches where the cortex and medulla join. Small vessels come o? these arches and run up through the cortex, giving o? small branches in each direction. These end in a tuft of capillaries, enclosed in Bowman’s capsule, which forms the end of the uriniferous tubules just described; capillaries with capsule constitute a glomerulus.
After circulating in the glomerulus, the blood leaves by a small vein, which again divides into capillaries on the walls of the uriniferous tubules. From these it is ?nally collected into the renal veins and then leaves the kidney. This double circulation (?rst through the glomerulus and then around the tubule) allows a large volume of ?uid to be removed from the blood in the glomerulus, the concentrated blood passing on to the uriniferous tubule for removal of parts of its solid contents. Other arteries come straight from the arches and supply the medulla direct; the blood from these passes through another set of capillaries and ?nally into the renal veins. This circulation is con?ned purely to the kidney, although small connections by both arteries and veins exist which pass through the capsule and, joining the lumbar vessels, communicate directly with the aorta.
Function The kidneys work to separate ?uid and certain solids from the blood. The glomeruli ?lter from the blood the non-protein portion of the plasma – around 150–200 litres in 24 hours, 99 per cent of which is reabsorbed on passing through the convoluted tubules.
Three main groups of substances are classi?ed according to their extent of uptake by the tubules:
(1) SUBSTANCES ACTIVELY REABSORBED These include amino acids, glucose, sodium, potassium, calcium, magnesium and chlorine (for more information, see under separate entries).
(2) SUBSTANCES DIFFUSING THROUGH THE TUBULAR EPITHELIUM when their concentration in the ?ltrate exceeds that in the PLASMA, such as UREA, URIC ACID and phosphates.
(3) SUBSTANCES NOT RETURNED TO THE BLOOD from the tubular ?uid, such as CREATINE, accumulate in kidney failure, resulting in general ‘poisoning’ known as URAEMIA.... structure each kidney is about 10 cm long,

Consumption of tea can lead to many health benefits, as it is a natural beverage. There are various types of tea which help with kidney problems, as well. Find out more about teas for kidney!
Why drink tea for kidney
Damage of kidney (nephropathy) can lead to various problems. Some of the more common ones include kidney failure (also known as renal failure), kidney tumors (Wilms tumor or renal cell carcinoma), and kidney stones.
Consumption of tea can help treat these problems, prevent them or slow down their progress. They also help maintain the kidneys in a healthy condition, which leads to other health benefits, such as regulating the blood pressure.
Teas for kidney
There are several types of tea which help with kidney problems. Most of them are herbal teas.
Club moss tea, elderberry tea, saw palmetto tea, and cleavers tea have a cleansing effect, helping with the detoxification process. In the case of kidney failures, you can add centaury tea and Ceylon tea to your treatment.
For other kidney problems, as well as the ones mentioned before, drink fenugreek tea, burdock tea, sassafras tea, banaba tea, sage tea, juniper tea, privet tea, orris tea, or milk thistle tea. Also, in order to have a pair of healthy kidneys, you can drink cranberry tea, goji tea, rehmannia tea, dandelion tea, lemongrass tea, or kukicha tea.
Tea for kidney stones
Kidney stones are some of the most common kidney problems. They are solid concretions or crystal aggregations which are formed in the kidneys and eliminated through urine.
Black tea is one type of tea that can help with kidney stones. Other teas, herbal ones this time, are butterbur tea, corn silk tea, uva ursi tea, stone root tea, triphala tea, marshmallow tea, alfalfa tea, pipsissewa tea, and abuta tea.
Tea for kidney side effects
Side effects vary from one tea to another. Generally, it is recommended to speak to your doctor first, before consuming one of these teas, if you are pregnant or breastfeeding.
Also, you have to be careful with black tea, which has a pretty high caffeine content. If your body can’t take caffeine, it might lead to unwanted side effects: headaches, nervousness, sleep problems, vomiting, diarrhea, irritability, irregular heartbeats, tremors, dizziness, or ringing in the ears.
Teas you shouldn’t drink
If you’ve got kidney problems, there are a few types of tea you should not drink. The list includes oolong tea, horse chestnut tea, lovage tea, wu yi tea, lemon verbena tea, rue tea, and periwinkle tea.
Also, you might get kidney problems (even kidney stones) if you drink a high amount of boneset tea, yohimbe tea, yerba mate tea, essiac tea, parsley tea, osha tea, and meadowsweet tea.
However, juniper tea and horsetail tea are part of a special class. They both help with kidney problems, but they have to be consumed properly. Over consumption can lead to kidney pains in the case of juniper tea, or kidney stones in the case of horsetail tea.
You can protect your kidney, as well as treat various kidney problems, by drinking tea. Besides this, you’ll discover that, based on the type of tea you drink, you’ll get plenty of health benefits, as well. Have a cup of tea for kidney!... tea for kidney

If you’re experiencing abdominal pain and you’re sure it’s not a digestive tract ailment, it’s very possible that you’re suffering from a kidney disorder.
The same if the pain is localized in the back or on one side of your body. Usually, kidney problems appear when there’s something wrong with your urinary tract and not only.
Overexposing your body to low temperatures may cause urinary infections, impurity accumulations lead to kidney stones. Also, kidney problems can be caused by other health complaints, such as pulmonary edema and cancers.
However, it’s best to schedule an appointment with your doctor in order to find out what’s actually going on with your body.
How a Tea for Kidney Problems Works
A Tea for Kidney Problems’ main goal is to purify your body by triggering a positive response from it.
Once the main substances of these teas reach the affected areas, your organism produces enough endorphins (which are cells specialized in making you feel a lot better by bringing relief to your wounds) and antibodies to reconstruct the damaged tissue.
Efficient Tea for Kidney Problems
In order to work properly, a Tea for Kidney Problems needs to be both efficient and one hundred percent safe. Also, it must contain the right amount of nutrients, natural enzymes, volatile oils, antioxidants and minerals (sodium, magnesium, iron and manganese).
This way, that tea will make your body eliminate the unwanted impurities and improve your kidney function. If you don’t know which teas would be appropriate for your condition, here’s a list to choose from:
- Dandelion Tea – can be prepared from dandelion roots and it’s also a great adjuvant in diarrhea and urinary infection cases. This Tea for Kidney Problems has a bitter taste, but you can add ginger, lemon, mint or honey in order to make it more adequate for you.
Avoid it at all costs if you’re pregnant or breastfeeding: due to its strong purgative and diuretic properties, Dandelion Tea can cause uterine contractions which may lead to miscarriages.
- Marshmallow Root Tea – this lovely tea with a hint of Christmas is useful for a large variety of problems, from infertility to gastrointestinal and digestive complaints. Take a sip at every 5 minutes for an hour and enjoy the wonderful health benefits!
- Buchu Tea – contains antioxidants and antibacterial agents, being a great help in cases of cystitis, urethritis and kidney failure. This Tea for Kidney acts like a natural diuretic and should not be taken by pregnant women.
- Green Tea – as the scientists have proved, this decoction contains all the ingredients necessary to sustain life, so it’s useful for many problems, not just kidney disorders. However, don’t take it if you’re experiencing menstrual and menopausal symptoms (it can cause uterine contractions and stomach acidity).
Tea for Kidney Problems Side Effects
When taken properly, these teas are generally safe. However, exceeding the number of cups recommended per day might lead to a number of health problems such as miscarriages, hallucinations, headaches and skin rash.
If you’ve been taking one of these teas and something doesn’t feel quite right, talk to your doctor as soon as possible. Don’t take a Tea for Kidney Problems if you’re pregnant, breastfeeding, on blood thinners or anticoagulants. The same advice if you’re preparing for a surgery.
If you have the medical approval and there’s nothing that could interfere with your treatment, choose a Tea for Kidney problems that fits best your needs and give it a try today!

See kidney, polycystic.... polycystic kidney
A cancerous tumour of the kidney. Most kidney cancers originate in the kidney itself, but in rare cases cancer spreads to the kidney from another organ. There are 3 main types of kidney cancer. The most common, renal cell carcinoma, usually occurs in people over 40. Nephroblastoma (also called Wilms’ tumour) is a fast-growing tumour that mainly affects children under 5. Transitional cell carcinoma arises from cells lining the renal pelvis; it is more common in smokers or those who have taken analgesic drugs for a long time.Symptoms of kidney cancer vary. It is often symptomless in the early stages, although later there may be blood in the urine. All types require surgical removal of the kidney and sometimes also of the ureter. For nephroblastoma, surgery is followed by treatment with anticancer drugs. Kidney cancer is likely to be fatal if it has spread to other organs before treatment is started.... kidney cancer
Techniques for visualizing the kidneys, usually performed for diagnosis. Ultrasound scanning can be used to identify kidney enlargement, a cyst or tumour, and the site of any blockage. Conventional X-rays show the outline of the kidneys and most kidney stones. Intravenous urography shows the internal anatomy of the kidney and ureters. Angiography is used to image blood circulation through the kidneys. CT scanning and MRI provide detailed cross-sectional images and can show abscesses or tumours. Two types of radionuclide scanning are used for the kidney: DMSA and DTPA scanning. DMSA is a substance given by intravenous injection that binds to cells in the kidney tubule, giving a single, static picture of the kidneys. DTPA, also given intravenously, is filtered in the kidneys and passes out in the urine. Pictures taken at intervals record its passage through the urinary tract and show kidney function. ... kidney imaging

n. X-ray examination of the urinary bladder after filling it with a contrast medium. The X-ray images thus obtained are known as cystograms. Cystography is most commonly performed to detect reflux of urine from the bladder to the ureters, usually in children (see vesicoureteric reflux). In adults it is often performed to detect bladder injury or perforation. If films are taken during voiding (micturating cystourethrogram) then the urethra can also be observed (see urethrography). The examination can also be performed in conjunction with manometry (see bladder pressure study).... cystography

n. the presence of stones (calculi) in the urinary bladder. The stones are either formed in the bladder, due to obstruction, urinary statis, and infection (primary calculi), or pass to the bladder after being formed in the kidneys (secondary calculi). They cause pain, the passage of bloody urine, and interruption of the urinary stream and should be removed surgically. See calculus.... cystolithiasis
(vesicofixation) n. a surgical operation to fix the urinary bladder (or a portion of it) in a different position. It may be performed as part of the repair or correction of a prolapsed bladder.... cystopexy
n. an operation to enlarge the capacity of and to decrease the pressure within the bladder by incorporating a segment of bowel. In a clam cystoplasty, the bladder is cut across transversely from one side of the neck to the other side through the dome (fundus) of the bladder and a length of the ileum, jejunum, or colon is inserted as a patch. In the operation of ileocaecocystoplasty, the dome is removed by cutting across the bladder transversely or sagittally above the openings of the ureters; it is replaced by an isolated segment of caecum and terminal ileum. In ileocystoplasty the bladder is enlarged by an opened-out portion of small intestine. The bladder may be totally replaced by a reservoir constructed from either small or large intestine (see cystectomy).... cystoplasty
