Urinary Diversion

One of a variety of procedures for collecting and diverting URINE from its customary channel of excretion following surgical removal of the bladder for disease, usually cancer. The ureters (see URETER) may be implanted in the large bowel, or a reservoir or small pouch may be fashioned using a section of small or large INTESTINE. In the latter method the pouch is emptied through a small STOMA using a catheter (see CATHETERS), thus dispensing with the need for a urinary drainage bag.... urinary diversion

Endocrine Glands

Organs whose function it is to secrete into the blood or lymph, substances known as HORMONES. These play an important part in general changes to or the activities of other organs at a distance. Various diseases arise as the result of defects or excess in the internal secretions of the di?erent glands. The chief endocrine glands are:

Adrenal glands These two glands, also known as suprarenal glands, lie immediately above the kidneys. The central or medullary portion of the glands forms the secretions known as ADRENALINE (or epinephrine) and NORADRENALINE. Adrenaline acts upon structures innervated by sympathetic nerves. Brie?y, the blood vessels of the skin and of the abdominal viscera (except the intestines) are constricted, and at the same time the arteries of the muscles and the coronary arteries are dilated; systolic blood pressure rises; blood sugar increases; the metabolic rate rises; muscle fatigue is diminished. The super?cial or cortical part of the glands produces steroid-based substances such as aldosterone, cortisone, hydrocortisone, and deoxycortone acetate, for the maintenance of life. It is the absence of these substances, due to atrophy or destruction of the suprarenal cortex, that is responsible for the condition known as ADDISON’S DISEASE. (See CORTICOSTEROIDS.)

Ovaries and testicles The ovary (see OVARIES) secretes at least two hormones – known, respectively, as oestradiol (follicular hormone) and progesterone (corpus luteum hormone). Oestradiol develops (under the stimulus of the anterior pituitary lobe – see PITUITARY GLAND below, and under separate entry) each time an ovum in the ovary becomes mature, and causes extensive proliferation of the ENDOMETRIUM lining the UTERUS, a stage ending with shedding of the ovum about 14 days before the onset of MENSTRUATION. The corpus luteum, which then forms, secretes both progesterone and oestradiol. Progesterone brings about great activity of the glands in the endometrium. The uterus is now ready to receive the ovum if it is fertilised. If fertilisation does not occur, the corpus luteum degenerates, the hormones cease acting, and menstruation takes place.

The hormone secreted by the testicles (see TESTICLE) is known as TESTOSTERONE. It is responsible for the growth of the male secondary sex characteristics.

Pancreas This gland is situated in the upper part of the abdomen and, in addition to the digestive enzymes, it produces INSULIN within specialised cells (islets of Langerhans). This controls carbohydrate metabolism; faulty or absent insulin production causes DIABETES MELLITUS.

Parathyroid glands These are four minute glands lying at the side of, or behind, the thyroid (see below). They have a certain e?ect in controlling the absorption of calcium salts by the bones and other tissues. When their secretion is defective, TETANY occurs.

Pituitary gland This gland is attached to the base of the brain and rests in a hollow on the base of the skull. It is the most important of all endocrine glands and consists of two embryologically and functionally distinct lobes.

The function of the anterior lobe depends on the secretion by the HYPOTHALAMUS of certain ‘neuro-hormones’ which control the secretion of the pituitary trophic hormones. The hypothalamic centres involved in the control of speci?c pituitary hormones appear to be anatomically separate. Through the pituitary trophic hormones the activity of the thyroid, adrenal cortex and the sex glands is controlled. The anterior pituitary and the target glands are linked through a feedback control cycle. The liberation of trophic hormones is inhibited by a rising concentration of the circulating hormone of the target gland, and stimulated by a fall in its concentration. Six trophic (polypeptide) hormones are formed by the anterior pituitary. Growth hormone (GH) and prolactin are simple proteins formed in the acidophil cells. Follicle-stimulating hormone (FSH), luteinising hormone (LH) and thyroid-stimulating hormone (TSH) are glycoproteins formed in the basophil cells. Adrenocorticotrophic hormone (ACTH), although a polypeptide, is derived from basophil cells.

The posterior pituitary lobe, or neurohypophysis, is closely connected with the hypothalamus by the hypothalamic-hypophyseal tracts. It is concerned with the production or storage of OXYTOCIN and vasopressin (the antidiuretic hormone).

PITUITARY HORMONES Growth hormone, gonadotrophic hormone, adrenocorticotrophic hormone and thyrotrophic hormones can be assayed in blood or urine by radio-immunoassay techniques. Growth hormone extracted from human pituitary glands obtained at autopsy was available for clinical use until 1985, when it was withdrawn as it is believed to carry the virus responsible for CREUTZFELDT-JAKOB DISEASE (COD). However, growth hormone produced by DNA recombinant techniques is now available as somatropin. Synthetic growth hormone is used to treat de?ciency of the natural hormone in children and adults, TURNER’S SYNDROME and chronic renal insu?ciency in children.

Human pituitary gonadotrophins are readily obtained from post-menopausal urine. Commercial extracts from this source are available and are e?ective for treatment of infertility due to gonadotrophin insu?ciency.

The adrenocorticotrophic hormone is extracted from animal pituitary glands and has been available therapeutically for many years. It is used as a test of adrenal function, and, under certain circumstances, in conditions for which corticosteroid therapy is indicated (see CORTICOSTEROIDS). The pharmacologically active polypeptide of ACTH has been synthesised and is called tetracosactrin. Thyrotrophic hormone is also available but it has no therapeutic application.

HYPOTHALAMIC RELEASING HORMONES which affect the release of each of the six anterior pituitary hormones have been identi?ed. Their blood levels are only one-thousandth of those of the pituitary trophic hormones. The release of thyrotrophin, adrenocorticotrophin, growth hormone, follicle-stimulating hormone and luteinising hormone is stimulated, while release of prolactin is inhibited. The structure of the releasing hormones for TSH, FSH-LH, GH and, most recently, ACTH is known and they have all been synthesised. Thyrotrophin-releasing hormone (TRH) is used as a diagnostic test of thyroid function but it has no therapeutic application. FSH-LH-releasing hormone provides a useful diagnostic test of gonadotrophin reserve in patients with pituitary disease, and is now used in the treatment of infertility and AMENORRHOEA in patients with functional hypothalamic disturbance. As this is the most common variety of secondary amenorrhoea, the potential use is great. Most cases of congenital de?ciency of GH, FSH, LH and ACTH are due to defects in the hypothalamic production of releasing hormone and are not a primary pituitary defect, so that the therapeutic implication of this synthesised group of releasing hormones is considerable.

GALACTORRHOEA is frequently due to a microadenoma (see ADENOMA) of the pituitary. DOPAMINE is the prolactin-release inhibiting hormone. Its duration of action is short so its therapeutic value is limited. However, BROMOCRIPTINE is a dopamine agonist with a more prolonged action and is e?ective treatment for galactorrhoea.

Thyroid gland The functions of the thyroid gland are controlled by the pituitary gland (see above) and the hypothalamus, situated in the brain. The thyroid, situated in the front of the neck below the LARYNX, helps to regulate the body’s METABOLISM. It comprises two lobes each side of the TRACHEA joined by an isthmus. Two types of secretory cells in the gland – follicular cells (the majority) and parafollicular cells – secrete, respectively, the iodine-containing hormones THYROXINE (T4) and TRI-IODOTHYRONINE (T3), and the hormone CALCITONIN. T3 and T4 help control metabolism and calcitonin, in conjunction with parathyroid hormone (see above), regulates the body’s calcium balance. De?ciencies in thyroid function produce HYPOTHYROIDISM and, in children, retarded development. Excess thyroid activity causes thyrotoxicosis. (See THYROID GLAND, DISEASES OF.)... endocrine glands

Genito-urinary Medicine

The branch of medicine that deals with the effects of SEXUALLY TRANSMITTED DISEASES (STDS) on the URINARY TRACT, REPRODUCTIVE SYSTEM and other systems in the body. The specialty overlaps with GYNAECOLOGY (women’s urinary and reproductive systems) and UROLOGY (men’s urinary and reproductive system).... genito-urinary medicine

Urinary Bladder

The urinary bladder is a highly distensible organ for storing URINE. It consists of smooth muscle known as the detrusor muscle and is lined with urine-proof cells known as transitional cell epithelium.

The bladder lies in the anterior half of the PELVIS, bordered in front by the pubis bone and laterally by the side wall of the pelvis. Superiorly the bladder is covered by the peritoneal lining of the abdomen. The bottom or base of the bladder lies against the PROSTATE GLAND in the male and the UTERUS and VAGINA in the female.... urinary bladder

Bugleweed Tea For Endocrine Issues

Bugleweed Tea  is an important ingredient in the field of modern alternative medicine because it proved its efficiency against thyroid problems, as well as breast pain. Bugleweed Tea description Bugleweed is a low-growing flowering plant from the mint family, native to Europe. It is also known as sweet bugle and it grows in marshlands. The bugleweed has oval-shaped leaves which resemble spinach leaves. Bugleweed flowers grow in clusters and have a pink to blue color. This plant has a fresh, mild, mint-like aroma. The leaves and flowers are used for medicinal purposes. Bugleweed tea is the resulting beverage from brewing the abovementioned plant. Bugleweed Tea brewing To prepare Bugleweed tea:
  • add one teaspoonful of dried bugleweed herbs to a cup of boiling water
  • allow the mixture to steep for 10-15 minutes
Bugleweed tea may be drunk three times a day. Also, it can be applied topically either as tincture or as poultice. Bugleweed Tea benefits Bugleweed tea has been successfully used to:

Computerised Decision-support Systems

Also known as ‘expert systems’, these are computer software systems intended to help doctors make clinical decisions. Primary care medicine is especially noted for its uncertainty by virtue of being most patients’ ?rst point of contact with health care, confronting the clinician with many ‘undi?erentiated’ health problems. So far, these systems have not been as e?ective as expected because of a failure to ana-lyse the needs of primary care. Simple procedures to prompt the delivery of treatment to patients with chronic conditions have improved care quality, but work needs to be done on their cost-e?ectiveness. The aim of more complex computerised support systems will be to forecast likely future events and the possible e?ectiveness of proposed interventions, based on available information about the patient and an understanding of the risks and e?cacy of interventions by doctors and other experts.

One example, called ISABEL, can be accessed by paediatricians to check on their diagnosis and management of many childhood disorders.... computerised decision-support systems

Incontinence, Urinary

Involuntary passing of urine, often due to injury or disease of the urinary tract. There are several types. Stress incontinence refers to the involuntary escape of urine when a person coughs, picks up a heavy package, or moves excessively. It is common in women, particularly after childbirth, when the urethral sphincter muscles are stretched. In urge incontinence, also known as irritable bladder, an urgent desire to pass urine is accompanied by inability to control the bladder as it contracts. Once urination starts, it cannot be stopped. Total incontinence is a complete lack of bladder control due to an absence of sphincter activity, which may be associated with spinal cord damage. Overflow incontinence occurs in longterm urinary retention, often because of an obstruction such as an enlarged prostate gland. The bladder is always full, leading to constant dribbling of urine.Incontinence may also be due to urinary tract disorders (including infections, bladder stones, or tumours) or prolapse of the uterus or vagina. Incontinence due to lack of control by the brain commonly occurs in the young (see enuresis) or elderly and those with learning difficulties.

If weak pelvic muscles are causing stress incontinence, pelvic floor exercises may help. Sometimes, surgery may be needed to tighten the pelvic muscles or correct a prolapse. Anticholinergic drugs may be used to relax the bladder muscle if irritable bladder is the cause.

If normal bladder function cannot be restored, incontinence pants can be worn; men can wear a penile sheath leading into a tube connected to a urine bag. Some people can avoid incontinence by self-catheterization (see catheterization, urinary). Permanent catheterization is necessary in some cases.... incontinence, urinary

Urinary Retention

Inability to empty the bladder or difficulty in doing so. Urinary retention may be complete (urine cannot be passed voluntarily at all) or incomplete (the bladder fails to empty completely). In males, causes include phimosis, urethral stricture, prostatitis, a stone in the bladder (see calculus, urinary tract), and enlargement or tumour of the prostate (see prostate, enlarged; prostate, cancer of). In females, causes include pressure on the urethra from uterine fibroids or from a fetus. In either sex, the cause may be a bladder tumour. Retention may also be due to defective functioning of the nerve pathways supplying the bladder as a result of general or spinal anaesthesia, drugs affecting the bladder, surgery, injury to the nerve pathways, or disease of the spinal cord.

Complete retention causes discomfort and lower abdominal pain, except when nerve pathways are defective. The full bladder can be felt above the pubic bone. However, chronic or partial retention may not cause any serious symptoms. Retention can lead to kidney damage and, often, a urinary tract infection.Treatment of retention is by catheterization (see catheterization, urinary).

The cause is then investigated.

Obstruction can usually be treated; if nerve damage is the cause, permanent or intermittent catheterization is sometimes necessary.... urinary retention

Urinary Tract Infection

An infection anywhere in the urinary tract. It has differing symptoms, depending on the area affected. Urethritis causes a burning sensation when urine is being passed. Cystitis causes a frequent urge to pass urine, lower abdominal pain, haematuria, and, often, general malaise with a mild fever. Pyelonephritis causes fever and pain in the back under the ribs. Cystitis and pyelonephritis are almost always the result of a bacterial infection. Urethritis is often due to a sexually transmitted infection, such as gonorrhoea, but may have other causes. Urethral infections are more common in men. Infections further up the urinary tract are more common in women. In men, there is often a predisposing factor, such as an enlarged prostate gland (see prostate, enlarged). In women, pregnancy is a risk factor.

In both sexes, causes of urinary tract infections include stones (see calculus, urinary tract), bladder tumours, congenital abnormalities of the urinary tract, or defective bladder emptying as a result of spina bifida or a spinal injury. The risks of developing a urinary tract infection can be reduced by strict personal hygiene, drinking lots of fluids, and regularly emptying the bladder.

Urethritis can lead to the formation of a urethral stricture. Cystitis usually only causes complications if the infection spreads to the kidneys. Pyelonephritis, if it is left untreated, can lead to permanent kidney damage, septicaemia, and septic shock.

The infection is diagnosed by the examination of a urine culture. Further investigations using urography or ultrasound scanning may be necessary. Most infections of the urinary tract are treated with antibiotic drugs.... urinary tract infection

These include *frequency, *urgency, *nocturia, *incontinence, *hesitation, *intermittency, *terminal dribble, *dysuria, and *postmicturition dribble. These symptoms used to be known as prostatism. Sometimes they are due to benign prostatic hyperplasia (see prostate gland), but they may be due to *detrusor overactivity, excessive drinking, diuresis due to poorly controlled diabetes, or a urethral stricture.... lower urinary tract symptoms

Multiple Endocrine Neoplasia

(MEN) see MENS.... multiple endocrine neoplasia

Urinary Bladder, Diseases Of

Diseases of the URINARY BLADDER are diagnosed by the patient’s symptoms and signs, examination of the URINE, and using investigations such as X-RAYS and ULTRASOUND scans. The interior of the bladder can be examined using a cystoscope, which is a ?breoptic endoscope (see FIBREOPTIC ENDOSCOPY) that is passed into the bladder via the URETHRA.

Cystitis Most cases of cystitis are caused by bacteria which have spread from the bowel, especially Escherichia coli, and entered the bladder via the urethra. Females are more prone to cystitis than are males, owing to their shorter urethra which allows easier entry for bacteria. Chronic or recurrent cystitis may result in infection spreading up the ureter to the kidney (see KIDNEY, DISEASES OF).

Symptoms Typically there is frequency and urgency of MICTURITION, with stinging and burning on passing urine (dysuria), which is often smelly or bloodstained. In severe infection patients develop fever and rigors, or loin pain. Before starting treatment a urine sample should be obtained for laboratory testing, including identi?cation of the invading bacteria.

Treatment This includes an increased ?uid intake, ANALGESICS, doses of potassium citrate to make the urine alkaline to discourage bacterial growth, and an appropriate course of ANTIBIOTICS once a urine sample has been ana-lysed in the laboratory to con?rm the diagnosis and determine what antibiotics the causative organism is likely to respond to.

Stone or calculus The usual reason for the formation of a bladder stone is an obstruction to the bladder out?ow, which results in stagnant residual urine – ideal conditions for the crystallisation of the chemicals that form stones – or from long-term indwelling CATHETERS which weaken the natural mechanical protection against bacterial entry and, by bruising the lining tissues, encourage infection.

Symptoms The classic symptom is a stoppage in the ?ow of urine during urination, associated with severe pain and the passage of blood.

Treatment This involves surgical removal of the stone either endoscopically (litholapaxy); by passing a cystoscope into the bladder via the urethra and breaking the stone; or by LITHOTRIPSY in which the stone (or stones) is destroyed by applying ultrasonic shock waves. If the stone cannot be destroyed by these methods, the bladder is opened and the stone removed (cystolithotomy).

Cancer Cancer of the bladder accounts for 7 per cent of all cancers in men and 2·5 per cent in women. The incidence increases with age, with smoking and with exposure to the industrial chemicals, beta-napththylamine and benzidine. In 2003, 2,884 men and 1,507 women died of bladder cancer in England and Wales.

Symptoms The classical presenting symptom of a bladder cancer is the painless passing of blood in the urine – haematuria. All patients with haematuria must be investigated with an X-ray of their kidneys, an INTRAVENOUS PYELOGRAM (UROGRAM) and a cystoscopy.

Treatment Super?cial bladder tumours on the lining of the bladder can be treated by local removal via the cystoscope using DIATHERMY (cystodiathermy). Invasive cancers into the bladder muscle are usually treated with RADIOTHERAPY, systemic CHEMOTHERAPY or surgical removal of the bladder (cystectomy). Local chemotherapy may be useful in some patients with multiple small tumours.... urinary bladder, diseases of

Calculus, Urinary Tract

A stone in the kidneys, ureters, or bladder formed from substances in urine.

Most urinary tract stones are composed of calcium oxalate or other salts crystallized from the urine. These may be associated with a diet rich in oxalic acid (found in leafy vegetables and coffee); high levels of calcium in the blood as a result of hyperparathyroidism; or chronic dehydration. Other types of stone are associated with gout and some cancers. An infective stone is usually a result of chronic urinary tract infection.

In developing countries, bladder stones usually occur as a result of dietary deficiencies. In developed countries, they are usually caused by an obstruction to urine flow from the bladder and/or a longstanding urinary tract infection.

The most common symptom of a stone in the kidney or ureter is renal colic (a severe pain in the loin) that may cause nausea and vomiting. There may be haematuria (blood in the urine). A bladder stone is usually indicated by difficulty in passing urine. The site of the stone can usually be confirmed by intravenous or retrograde urography.

Renal colic is treated with bed rest and an opioid analgesic (painkiller).

With an adequate fluid intake, small stones are usually passed in the urine without problems.

The first line of treatment for larger stones is lithotripsy, which uses ultrasonic or shock waves to disintegrate the stones.

Alternatively, cytoscopy can be used to crush and remove stones in the bladder and lower ureter.

In some cases, surgery may be needed.... calculus, urinary tract

Catheterization, Urinary

Insertion of a sterile catheter into the bladder to drain urine. The procedure is used when a person is unable to empty the bladder normally or is incontinent (see incontinence, urinary). Urinary catheterization is also used during operations, in bladder function tests such as cystometry and cystourethrography, and to monitor urine production in the critically ill.... catheterization, urinary

Endocrine System

The collection of glands around the body that produce hormones.

These glands include the thyroid gland, pancreas, testes, ovaries, and adrenal glands.

Their hormones are responsible for numerous bodily processes, including growth, metabolism, sexual development and function, and response to stress.

Any increase or decrease in the production of a specific hormone interferes with the process it controls.

To prevent under- or overproduction, hormone secretion from many endocrine glands is regulated by the pituitary gland, which is in turn influenced by the hypothalamus in the brain according to a feedback mechanism.... endocrine system
