Urethral discharge
Urethral discharge is the excretion of fluid from the urinary meatus, which may be purulent, mucoid, thin, sanguineous, or clear. The volume may range from scant to profuse. It typically develops suddenly, most commonly in men with prostate infection or urethritis, and may indicate sexually transmitted infections (STIs) or other urinary tract pathology.
Pathophysiology
Prostatitis: Infection and inflammation of the prostate gland produce increased prostatic secretions, which may exit via the urethra.
Urethritis: Inflammation of the urethral mucosa, often due to Neisseria gonorrhoeae, Chlamydia trachomatis, or other pathogens, causes mucopurulent exudate.
Reiter’s Syndrome (Reactive Arthritis): Post-infectious autoimmune response leads to urethritis and systemic manifestations (arthritis, conjunctivitis, mucocutaneous lesions).
Chronic prostatitis: May cause persistent, milky, or clear discharge due to low-grade inflammation of the prostate and seminal vesicles.
History and Physical Examination
History
Onset and progression: Sudden or gradual, intermittent or persistent.
Discharge characteristics: Color, consistency (thin, mucoid, purulent), quantity.
Associated urinary symptoms: Dysuria, burning, frequency, urgency, hesitancy, nocturia, weak stream.
Other systemic symptoms: Fever, chills, perineal fullness, lower back pain, arthralgia.
Sexual history: Recent sexual contacts, new partners, history of STIs.
Past medical history: Prostate disease, urinary tract infection, recent instrumentation or surgery.
Physical Examination
Inspect urethral meatus: Look for erythema, swelling, and presence of discharge.
Obtain specimens: Collect urethral discharge for culture using proper technique.
Urine testing: Perform urinalysis, culture, and consider the three-glass urine test for prostatitis evaluation.
Prostate examination (male): Palpate for tenderness, bogginess, enlargement; avoid prostate massage in acute prostatitis due to risk of bacteremia.
Systemic examination: Assess for fever, lymphadenopathy, signs of Reiter’s syndrome (arthritis, conjunctivitis, mucocutaneous lesions).
Medical causes
Cause | Onset | Key Features | Associated Signs | Pathophysiology | Management |
Acute prostatitis | Sudden | Purulent urethral discharge, dysuria | Fever, chills, lower back pain, myalgia, perineal fullness | Bacterial infection (often E. coli) → prostate inflammation | Empiric antibiotics, analgesia, hydration, bed rest, avoid prostate massage, monitor urine retention |
Chronic prostatitis | Gradual, persistent | Thin, milky, or clear urethral discharge; may appear in morning | Dull perineal/rectal ache, ejaculatory pain, urinary frequency/urgency | Low-grade chronic inflammation of prostate/seminal vesicles | Long-term antibiotics, symptom management, increased fluids, sitz baths, sexual activity may help symptom relief |
Urethritis (STI-related, e.g., gonococcal, chlamydial) | Acute | Scant to profuse discharge: thin, mucoid, or purulent | Dysuria, urinary frequency, itching/burning at meatus | Infection/inflammation of urethral mucosa | Appropriate antibiotic therapy based on causative organism, partner notification, abstain until treatment complete |
Reiter’s syndrome (reactive arthritis) | 1–2 weeks post-infection | Urethral discharge, acute urethritis | Asymmetrical arthritis, conjunctivitis, mucocutaneous lesions | Autoimmune response post-infection | NSAIDs, antibiotics for triggering infection, supportive care |
Iatrogenic/post-procedural | Variable | Discharge post-catheterization or instrumentation | Local erythema, dysuria | Mechanical irritation or infection | Symptomatic care, antibiotics if infection confirmed |
Special considerations
Acute prostatitis: Advise hot sitz baths several times daily, increased fluid intake, frequent voiding, and avoidance of caffeine, tea, and alcohol. Monitor for urinary retention.
Three-glass urine test:
Glass #1: First-voided urine (anterior urethra).
Glass #2: Midstream urine (bladder).
Glass #3: Residual urine (prostate and seminal vesicles).
Observation: Note urine color, odor, and presence of pus/mucus shreds. Confirm diagnosis via microscopy and culture.
Urethral discharge specimen collection in males and females:
Patient | Procedure | Notes / Precautions |
Male | 1. Void a small amount of urine first (optional). 2. Retract foreskin if uncircumcised. 3. Collect discharge from urethral meatus using a sterile swab. 4. Rotate swab gently to absorb sample. 5. Place swab into transport medium. | - Avoid touching surrounding skin. - Collect before starting antibiotics. - Refrain from urinating 1–2 hours before collection if possible. |
Female | 1. Patient lies in lithotomy position. 2. Gently separate labia minora. 3. Collect discharge from urethral meatus using sterile swab. 4. Rotate swab gently. 5. Place swab into transport medium. | - Avoid contaminating swab with vaginal secretions. - Collect before antibiotics. - Mild discomfort may occur. |
Patient counseling
Acute prostatitis: Avoid sexual activity until acute symptoms subside.
Chronic prostatitis: Regular sexual activity may relieve symptoms.
STI-related urethritis: Complete full course of antibiotics, abstain until partner treated, and practice safe sex.
General: Maintain hydration, practice good genital hygiene, and follow-up for persistent or recurrent symptoms.
Pediatric pointers
Urethral discharge in children warrants careful evaluation for sexual or physical abuse.
Assess for congenital or urinary tract anomalies if infection suspected.
Geriatric pointers
In elderly males, urethral discharge is less likely due to STIs; more commonly associated with prostatitis or urinary tract infection.
Consider comorbidities such as benign prostatic hyperplasia or catheterization.
