Summary about Disease
Non-specific urethritis (NSU) is an inflammation of the urethra (the tube that carries urine from the bladder to the outside of the body) that is not caused by gonorrhea or chlamydia. It involves symptoms of urethritis but without a confirmed bacterial infection of gonorrhea or chlamydia.
Symptoms
Pain or burning sensation while urinating
Discharge from the urethra (may be clear, white, or yellowish)
Itching or irritation near the opening of the urethra
Pain during sexual intercourse
Blood in urine (rare)
Causes
The exact cause of NSU can be difficult to determine. Possible causes include:
Bacterial infections (other than gonorrhea or chlamydia, such as Mycoplasma genitalium)
Viral infections (such as herpes simplex virus)
Irritation from chemicals (e.g., spermicides, soaps, douches)
Trauma or injury to the urethra
Medicine Used
4. Medicine used
Antibiotics are prescribed if a bacterial infection is suspected or confirmed. Common antibiotics include azithromycin, doxycycline, or erythromycin.
If a specific organism like Mycoplasma genitalium is identified, specific antibiotics targeting that organism are used.
Is Communicable
Yes, NSU caused by infection can be communicable, especially if caused by bacteria or viruses that can be sexually transmitted.
Precautions
Practice safe sex: Use condoms consistently and correctly.
Avoid douching or using harsh soaps or spermicides that can irritate the urethra.
Inform sexual partners if you have NSU.
Complete the full course of antibiotics, even if symptoms improve.
Avoid sexual activity until treatment is completed and symptoms have resolved.
How long does an outbreak last?
With appropriate treatment, symptoms typically resolve within 1-2 weeks. Untreated NSU can persist for weeks or months and may lead to complications.
How is it diagnosed?
Physical examination: To assess symptoms and check for discharge.
Urine test: To rule out gonorrhea and chlamydia. A urine culture may be done to identify other bacteria.
Urethral swab: To collect a sample of discharge for testing, if present.
Timeline of Symptoms
9. Timeline of symptoms The onset of symptoms can vary. It can appear days to weeks after exposure (if caused by an infection). Some people may not experience any symptoms at all. The symptoms can last from a few days to several weeks if left untreated.
Important Considerations
It's crucial to get tested for gonorrhea and chlamydia even if NSU is suspected, as these infections often have similar symptoms.
Recurrent NSU is possible.
Proper diagnosis and treatment are important to prevent complications and transmission to sexual partners.
Avoid self-treating and always consult a healthcare professional.
