Acute urethritis and periurethral complications
Definition
Acute urethritis is inflammation of the urethra, usually infectious (gonococcal or nongonococcal).
Clinical presentation
- Urethral discharge (purulent, mucoid).
- Dysuria, itching, burning.
- Urethral pain.
- Complications include stricture, abscess, and fistula.
Diagnosis
- Microscopy of the discharge may be used to confirm inflammation and provide a preliminary assessment for gonococcal infection.
- Main tests: NAAT or PCR for Neisseria gonorrhoeae and Chlamydia trachomatis; gonococcal culture with susceptibility testing when resistance or treatment failure is suspected.
- Test for Mycoplasma genitalium in persistent or recurrent nongonococcal urethritis, or according to the local protocol. Routine testing for Ureaplasma spp. is not required in every patient.
- Urethrography if a stricture is suspected.
Treatment
- Select empirical therapy according to the syndrome and local protocol. For probable uncomplicated gonorrhea, the international reference regimen is a single intramuscular dose of ceftriaxone 500 mg for patients weighing less than 150 kg, or 1 g for those weighing 150 kg or more; add doxycycline if chlamydial infection has not been excluded. Routine combination with azithromycin is not the standard for all patients.
- Once test results are available, provide targeted therapy, check adherence, and assess persistent symptoms.
- Sexual partners require evaluation and treatment according to epidemiological indications; advise abstinence until treatment and the specified waiting period are complete.
- Drain an abscess.
- Urethrotomy or dilatation for a stricture.
Algorithm
| Step | Action |
|---|---|
| 1 | Assess discharge, dysuria, sexual history, complications, and allergies |
| 2 | NAAT or PCR for gonorrhea and chlamydia; gonococcal culture as indicated |
| 3 | Start syndromic treatment according to the local protocol; do not routinely combine ceftriaxone with azithromycin |
| 4 | Add appropriate treatment if chlamydial infection has not been excluded |
| 5 | Evaluate and treat partners; advise on abstinence and prevention |
| 6 | For persistent symptoms, assess for M. genitalium, resistance, an abscess, or a stricture |
