Catheterization, Urinary: From 1 Different Sources


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.

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

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

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

Catheterization, Cardiac

A diagnostic test in which a fine, sterile catheter is introduced into the heart via a blood vessel. It is used to diagnose and assess the extent of congenital heart disease (see heart disease, congenital) and coronary artery disease, and to diagnose and treat some disorders of the heart valves (see valvuloplasty). During the procedure, the pressure within the heart’s chambers can be measured, samples of blood and tissue can be taken, and a radiopaque substance can be injected to allow the heart’s cavities to be X-rayed.... catheterization, cardiac

Urinary System

Intermittent Self-catheterization

(clean intermittent self-catheterization, ISC, CISC) a procedure in which the patient periodically passes a disposable catheter through the urethra into the bladder for the purpose of emptying it of urine. It is increasingly used in the management of patients of both sexes (including children) with chronic *retention and large residual urine volumes, often due to *neuropathic bladder. ISC may prevent back pressure and dilatation of the upper urinary tract with consequent infection and incontinence.... intermittent self-catheterization

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

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

Lower Urinary Tract Symptoms

(LUTS) symptoms occurring during urine storage, voiding, or immediately after. 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

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

Catheterization

n. the introduction of a *catheter into a hollow organ or vessel. In urethral catheterization a catheter is introduced into the bladder through the urethra to relieve obstruction to the outflow of urine (see also intermittent self-catheterization). Catheters can also be passed above the pubis through the anterior abdominal wall (suprapubic catheterization) directly into a full bladder if urethral catheterization is not possible. Cardiac catheterization entails the introduction of special catheters into the chambers of the heart. This allows the measurement of pressures in the chambers and pressure gradients across the heart valves, as well as the injection of contrast medium for visualization of structures using X-rays (see coronary angiography). Vascular catheterization enables the introduction into the arteries or veins of: (1) contrast medium for angiography or venography; (2) drugs to constrict or expand vessels or to dissolve a thrombus (see thrombolysis); (3) metal coils or other solid materials to block bleeding vessels or to thrombose *aneurysms (see embolization); (4) devices for monitoring pressures within important vessels (e.g. *Swan-Ganz catheters for monitoring pulmonary artery pressure in critically ill patients); or (5) balloons and *stents to relieve obstruction.... catheterization
