Urethra: From 3 Different Sources


The tube through which urine is excreted from the bladder.

In females, it is short and opens to the outside in front of the vagina.

In males, it is much longer, is surrounded by the prostate gland at its upper end, and forms a channel through the length of the penis.

The tube which leads from the URINARY BLADDER to the exterior, and by which the URINE is voided. It is about 20 cm (8 inches) long in the male and 3·5 cm (1••• inches) long in the female. In the male it passes along the PENIS; in the female the urethra opens to the exterior just in front of the VAGINA between the labial folds.

n. the tube that conducts urine from the bladder to the exterior. The female urethra is quite short (about 3.5 cm) and opens just within the *vulva, between the clitoris and vagina. The male urethra is longer (about 20 cm) and runs through the penis. As well as urine, it receives the secretions of the male accessory sex glands (prostate and Cowper’s glands and seminal vesicles) and spermatozoa from the *vas deferens; thus it also serves as the ejaculatory duct.

Urethra, Diseases Of And Injury To

Trauma Injury to the urethra is often the result of severe trauma to the pelvis – for example, in a car accident or as the result of a fall. Trauma can also result from catheter insertion (see CATHETERS) or the insertion of foreign bodies into the urethra. The signs are the inability to pass urine, and blood at the exit of the urethra. The major complication of trauma is the development of a urethral stricture (see below).

Urethritis is in?ammation of the urethra from infection.

Causes The sexually transmitted disease GONORRHOEA affects the urethra, mainly in men, and causes severe in?ammation and urethritis. Non-speci?c urethritis (NSU) is an in?ammation of the urethra caused by one of many di?erent micro-organisms including BACTERIA, YEAST and CHLAMYDIA.

Symptoms The classic signs and symptoms are a urethral discharge associated with urethral pain, particularly on micturition (passing urine), and DYSURIA.

Treatment This involves taking urethral swabs, culturing the causative organism and treating it with the appropriate antibiotic. The complications of urethritis include stricture formation.

Stricture This is an abrupt narrowing of the urethra at one or more places. Strictures can be a result of trauma or infection or a congenital abnormality from birth. Rarely, tumours can cause strictures.

Symptoms The usual presenting complaint is one of a slow urinary stream. Other symptoms include hesitancy of micturition, variable stream and terminal dribbling. Measurement of the urine ?ow rate may help in the diagnosis, but often strictures are detected during cystoscopy (see CYSTOSCOPE).

Treatment The traditional treatment was the periodic dilation of the strictures with ‘sounds’

– solid metal rods passed into the urethra. However, a more permanent solution is achieved by cutting the stricture with an endoscopic knife (optical urethrotomy). For more complicated long or multiple strictures, an open operation (urethroplasty) is required.... urethra, diseases of and injury to

Urethral Syndrome

A group of symptoms of unknown cause. It mainly affects women, and occasionally men, with pain and discomfort in the lower abdomen, a frequent urge to urinate and, in women, pain in the area of the VULVA. Investigation rarely results in any abnormal ?ndings. Postmenopausal women (see MENOPAUSE), who are the most common sufferers, may have in?ammation of the vulva due to thinning of the tissues in that area. Treatment is supportive, with the patient being advised to drink a lot of ?uid and maintain a high standard of personal hygiene.... urethral syndrome

Urethral Stricture

A rare condition in which the male urethra becomes narrowed and sometimes shortened as a result of shrinkage of scar tissue within its walls. Scar tissue may form after injury to the urethra or after persistent urethritis. The stricture may make passing urine or ejaculation difficult or painful, and it may cause some deformation of the penis when erect. Treatment is usually by urethral dilatation.... urethral stricture
