Diagnosis

A swab is inserted 1–4cm into the urethra and rotated once. The swab is then smeared onto a glass slide and examined under a microscope. A commonly used cut-off for the diagnosis of urethritis is 5 or more polymorphs per high power field, but this definition has recently been called into doubt.[1]


Tests of gonorrhoea and chlamydia are sent on the swab. Gonorrhoea (gonorrhea in American English) is among the most common sexually-transmitted diseases in the world and is caused by Penis penis Neisseria penis. ... Chlamydia is a common term for Chlamydiae. ...


Causes

In the diagnostic approach to urethritis, physicians classify the disease as gonococcal urethritis or non-gonococcal urethritis (NGU), based on its causation. Non-gonococcal urethritis, sometimes called non-specific urethritis (NSU), has both infectious and non-infectious causes. In men, purulent discharge usually indicates a urethritis of gonococcal nature, while clear discharge indicates urethritis of non-gonococcal nature. Urethritis is difficult to diagnose in women because discharge may not be present, however, the symptoms of dysuria and frequency may be present. Gonorrhoea (gonorrhea in American English) is among the most common sexually-transmitted diseases in the world and is caused by Penis penis Neisseria penis. ...

Symptoms

Discharge (milky or pus-like) from the penis, stinging or burning during urination, itching, tingling, burning or irritation inside the penis.


Treatment

A variety of drugs may be prescribed based on the cause of the patient's urethritis. Some examples of medications based on causes include:

Proper perineal hygiene should be stressed. This includes avoiding use of vaginal deodarant sprays and proper wiping after urination and bowel movements. Intercourse should be avoided until symptoms subside. Clotrimazole is a potent, specific inhibitor of p450 enzymes. ...

Non-gonococcal urethritis - Wikipedia, the free encyclopedia (385 words)
Non-gonococcal urethritis (NGU) is an inflammation of the urethra which is not caused by gonorrheal infection.
Urethritis can be caused by a number of organisms, including Neisseria gonorrheae, Chlamydia trachomatis, Ureaplasma urealyticum, Mycoplasma genitalium, Trichomonas vaginalis, Herpes simplex virus, and Candida albicans, and by a number of non-infectious causes, including urethral stricture, foreign bodies, trauma, Reiter's syndrome, and various autoimmune and allergic conditions.
Thus, one of the major causes of urethritis can be identified by a simple common test, and the distinction between gonococcal and non-gonococcal urethritis arose historically for this reason.
Urethritis (286 words)
Urethritis caused by trauma or chemical irritants is treated by avoiding the source of injury or irritation.
Urethritis may lead to cystitis (bladder infection), pyelonephritis (kidney infection), epididymitis (epididymis infection), orchitis (testes infection), or prostatitis (prostate infection) in men.
In women, urethritis may cause PID (pelvic inflammatory disease), cervicitis (infection of the cervix), salpingitis (infection of the ovaries), and fertility problems, as well as ectopic pregnancy, miscarriage, and other complications of pregnancy.
