Urethritis

Urethritis is an inflammation of the urethra, the tube that carries urine from the bladder out of the body. It is characterized by pain or discomfort during urination (dysuria), a frequent urge to urinate, and discharge from the urethra. Urethritis is commonly caused by sexually transmitted infections (STIs), but non-infectious causes also exist. Prompt diagnosis and treatment are crucial to prevent complications.

The most common cause of urethritis is infection, particularly STIs such as Neisseria gonorrhoeae (gonorrhea) and Chlamydia trachomatis (chlamydia). Other infectious agents include Trichomonas vaginalis (trichomoniasis), Mycoplasma genitalium, and herpes simplex virus (HSV). Non-infectious causes can include chemical irritants (e.g., spermicides, lubricants, soaps), trauma, or mechanical irritation from urethral instrumentation.

Infectious urethritis occurs when pathogens ascend into the urethra, colonize the mucosal lining, and trigger an inflammatory response. This involves the release of inflammatory mediators, influx of leukocytes (e.g., neutrophils), and damage to the urethral epithelium. This inflammation leads to swelling, increased mucus production (discharge), and irritation of the urethral lining, resulting in the characteristic symptoms of dysuria and discharge. In gonococcal urethritis, N. gonorrhoeae adheres to urethral epithelial cells and triggers an acute inflammatory response. Chlamydial urethritis often involves an initial asymptomatic infection followed by a more indolent inflammatory process.

Urethritis is a common condition, particularly in sexually active individuals. In men, it is more frequently diagnosed and reported. The incidence varies geographically and is influenced by local STI prevalence rates. Young adults aged 15-45 years are most commonly affected. Rates are higher in populations with higher sexual risk behaviors.

• Unprotected sexual intercourse
• Multiple sexual partners
• History of sexually transmitted infections
• New sexual partner
• Presence of other STIs
• Poor hygiene
• Use of irritating hygiene products
• Urethral instrumentation

A. Early Symptoms

• Burning or stinging sensation during urination (dysuria)


• Urgent need to urinate


• Frequent urination B. Common Symptoms


• Urethral discharge (may be clear, white, yellow, or greenish)


• Itching or irritation at the tip of the penis (in men)


• Redness and swelling around the urethral opening C. Advanced Symptoms


• Pain during ejaculation


• Blood in urine (hematuria) or semen (hematospermia)


• Pain in the lower abdomen or perineum D. Emergency Symptoms


• Severe fever


• Chills


• Severe abdominal pain


• Inability to urinate


• Disseminated gonococcal infection symptoms (e.g., joint pain, skin lesions)

Vital signs are typically normal unless systemic complications arise.
Inspection: May reveal redness and swelling of the urethral meatus, and visible urethral discharge.
Palpation: Tenderness may be elicited in the urethra or surrounding tissues. In men, prostatic tenderness might be present in complicated cases.
Auscultation: Typically normal.

A. Clinical Assessment
Detailed sexual history, symptom review, and physical examination. B. Laboratory Testing
Microscopic examination of urethral discharge, nucleic acid amplification tests (NAATs) for common STIs, urinalysis. C. Imaging Studies
Generally not required for uncomplicated urethritis. May be used to investigate complications like prostatic abscess or epididymitis. D. Functional Tests
Not typically used for diagnosis of urethritis itself. E. Biopsy Findings
Rarely performed for diagnosis of uncomplicated urethritis. May be considered in chronic or refractory cases to rule out other conditions. F. Genetic Testing
Not applicable for the diagnosis of urethritis. G. Differential Diagnosis
Prostatitis, cystitis, balanitis, urethral stricture, urinary tract stones, vaginitis (in women presenting with dysuria).

Test Name
Nucleic Acid Amplification Test (NAAT) for Chlamydia trachomatis and *Neisseria gonorrhoeae
*
Type: Urine Test | Swab Sample
Purpose: To detect the genetic material of Chlamydia and Gonorrhea pathogens.
Expected Findings: Positive for C. trachomatis and/or N. gonorrhoeae.
Interpretation: Confirms a diagnosis of chlamydial or gonococcal urethritis. Test Name
Gram Stain and Culture of Urethral Discharge
Type: Swab Sample
Purpose: To identify bacteria and assess antibiotic susceptibility.
Expected Findings: Presence of Gram-negative diplococci (suggestive of N. gonorrhoeae), or other bacteria.
Interpretation: Can diagnose bacterial causes of urethritis and guide antibiotic selection. Test Name
Urinalysis and Urine Culture
Type: Urine Test
Purpose: To detect inflammation (leukocytes, nitrites) and identify other potential urinary tract infections.
Expected Findings: Presence of leukocytes, positive urine culture (if a different UTI is present).
Interpretation: Helps rule out other causes of dysuria and can identify non-STI causes of urethritis if a pathogen is grown. Test Name
Wet Mount Microscopy of Urethral Discharge
Type: Swab Sample
Purpose: To detect Trichomonas vaginalis or clue cells (in women with vaginitis).
Expected Findings: Motile trichomonads.
Interpretation: Confirms trichomonal urethritis.

Purpose: To assess for complications of urethritis such as epididymitis, prostatic abscess, or urethral strictures.
Typical Findings: Ultrasound may show thickened or swollen epididymis (epididymitis), or an abscess cavity. MRI can delineate strictures.
Clinical Importance: Crucial for diagnosing and managing complicated urethritis.

• Prostatitis: May present with dysuria, but often accompanied by perineal pain, fever, and obstructive voiding symptoms.
• Cystitis: Primarily involves bladder inflammation, leading to frequency, urgency, and suprapubic pain, with less emphasis on urethral discharge.
• Balanitis: Inflammation of the glans penis, often associated with itching and discharge but typically affecting the glans rather than the urethra.
• Urethral Stricture: Can cause dysuria and a weak stream, but usually develops after trauma or infection and is a chronic condition.

• Epididymitis (inflammation of the epididymis)
• Prostatitis (inflammation of the prostate gland)
• Orchitis (inflammation of the testes)
• Infertility (due to scarring and obstruction)
• Urethral strictures (narrowing of the urethra)
• Reiter's syndrome (reactive arthritis)
• Pelvic inflammatory disease (in women, though urethritis is less common in women than cervicitis)
• Disseminated gonococcal infection

A. Lifestyle Modifications

• Abstinence from sexual activity during treatment.


• Safe sex practices (condom use) to prevent reinfection or transmission. B. Preventive Measures


• Consistent and correct use of condoms.


• Limiting the number of sexual partners. C. Medical Treatment

With appropriate antibiotic treatment, the prognosis for uncomplicated urethritis is excellent, with resolution of symptoms typically within a few days to a week. Recurrence can occur due to reinfection or inadequate treatment. Untreated or complicated urethritis can lead to long-term sequelae.

• Promote safe sexual practices, including consistent and correct condom use.
• Regular STI screening for sexually active individuals, especially those with multiple partners or symptoms.
• Prompt diagnosis and treatment of STIs.
• Educate individuals about the symptoms of urethritis and encourage early medical consultation.
