Treatment of Urethral Pain
The treatment of urethral pain depends critically on identifying the underlying cause: if infectious urethritis is suspected or confirmed, empiric antibiotic therapy targeting both gonorrhea and chlamydia is first-line, while non-infectious urethral pain syndrome requires a multimodal trial-and-error approach including analgesics, alpha-blockers, and psychological support.
Initial Diagnostic Approach
The first step is distinguishing infectious urethritis from non-infectious urethral pain syndrome, as this fundamentally changes management:
- Confirm urethritis objectively before initiating treatment by documenting at least one of: urethral discharge, positive leukocyte esterase test on first-void urine, or ≥5-10 polymorphonuclear leukocytes per high-power field on urethral swab or urine sediment 1, 2
- Symptoms alone without objective signs are insufficient for diagnosis or treatment initiation 1, 3
- Obtain testing for Neisseria gonorrhoeae and Chlamydia trachomatis when possible, as specific diagnosis improves compliance and enables partner notification 1
Treatment for Infectious Urethritis
First-Line Empiric Therapy
When diagnostic tools are unavailable or while awaiting results, treat empirically for both gonorrhea and chlamydia:
- Doxycycline 100 mg orally twice daily for 7 days PLUS ceftriaxone or cefixime for gonococcal coverage 2
- Alternative: Azithromycin 1 g orally as a single dose (particularly useful when compliance with 7-day regimens is questionable) 4, 2
Alternative Regimens
For patients intolerant of doxycycline:
- Erythromycin base 500 mg orally four times daily for 7 days OR erythromycin ethylsuccinate 800 mg orally four times daily for 7 days 4
Management of Persistent/Recurrent Urethritis
If symptoms persist after initial doxycycline treatment:
- First, rule out non-compliance or re-exposure to untreated partners (which warrants repeating the initial regimen) 1, 3
- Test for Trichomonas vaginalis using culture or NAAT on urethral swab or first-void urine 1, 3
- Consider doxycycline-resistant Ureaplasma urealyticum or Mycoplasma genitalium 1, 4
Recommended treatment for persistent urethritis:
- Metronidazole 2 g orally as a single dose OR Tinidazole 2 g orally as a single dose 1, 3
- PLUS Azithromycin 1 g orally as a single dose (if not used initially) 1, 3
- For M. genitalium specifically: Moxifloxacin 400 mg orally once daily for 7 days has demonstrated high efficacy 1
Partner Management (Critical Component)
- Refer all sexual partners from the preceding 60 days for evaluation and empiric treatment 1, 4, 3
- Partners should receive the same treatment regimen effective against chlamydia regardless of whether a specific pathogen was identified 1
- Both patient and partners must abstain from sexual intercourse until 7 days after single-dose therapy or until completion of 7-day regimens, provided symptoms have resolved 4, 3
- Expedited partner treatment (giving prescriptions to partners without examination) is advocated by the CDC and approved in many states 2
Follow-Up for Infectious Urethritis
- Test-of-cure is not recommended for patients who received appropriate treatment and are asymptomatic 1
- However, repeat testing at 3-6 months is recommended due to high reinfection rates (regardless of whether partners were treated) 1
- Patients should return if symptoms persist or recur after completing therapy 1, 3
Treatment for Non-Infectious Urethral Pain Syndrome
When infection has been excluded and pain persists, the diagnosis is urethral pain syndrome—a condition characterized by persistent or recurrent urethral pain (usually with voiding), daytime frequency, and nocturia without proven infection 5, 6.
Pathophysiology Understanding
The condition likely involves dysfunctional urethral epithelium becoming "leaky," leading to inflammation and eventual fibrosis—this explains why multiple therapeutic approaches may show benefit 5, 7.
Multimodal Treatment Approach
Because etiology is multifactorial, treatment requires a systematic trial-and-error approach 5, 6:
First-Line General Measures
- Analgesics for pain control 5
- Alpha-receptor blockers (e.g., tamsulosin) to reduce urethral spasm 5, 6
- Muscle relaxants for pelvic floor dysfunction 5
- Antimuscarinic therapy if overactive bladder symptoms predominate 5
Additional Therapeutic Options
- Topical vaginal estrogen in postmenopausal women or those with hypoestrogenism 5
- Psychological support is essential, as psychogenic factors may contribute 5, 6
- Physical therapy for pelvic floor dysfunction 5
- Acupuncture has shown success in some studies 6
- Trial of antibiotics if low-grade infection suspected despite negative cultures 5, 8
Refractory Cases
- Consider intravesical therapy or surgical intervention only after conservative measures fail 5
- Urethral dilation may be considered but carries risk of worsening fibrosis with repeated procedures 6
Treatment for Urethral Stricture Disease
If urethral pain is associated with obstructive voiding symptoms (weak stream, straining, incomplete emptying), stricture disease must be considered:
Diagnostic Confirmation
- Urethrocystoscopy, retrograde urethrography (RUG), voiding cystourethrography (VCUG), or ultrasound urethrography are required to diagnose and characterize strictures 1
- Determine stricture length and location before planning treatment 1
Treatment Options Based on Stricture Characteristics
For short (<2 cm) bulbar urethral strictures:
- Urethral dilation, direct visual internal urethrotomy (DVIU), or urethroplasty may all be offered as initial treatment 1
- Success rates: Dilation/DVIU 35-70% vs. urethroplasty 90-95% 1
- Urethroplasty provides superior long-term success but requires experienced surgeon 1
For strictures >2 cm or recurrent strictures:
- Urethroplasty is preferred as endoscopic treatment success rates are very low 1
For female urethral strictures:
- Urethroplasty using oral mucosa grafts or vaginal flaps is superior to endoscopic treatment 1
Urgent Management
- Urethral dilation, DVIU, or suprapubic cystostomy may be used for urgent management of symptomatic urinary retention 1
- Catheters may be removed after 24-72 hours following dilation/DVIU (no benefit to longer duration) 1
Common Pitfalls to Avoid
- Never treat based on symptoms alone without confirming objective signs of urethritis 1, 3
- Do not perform blind basketing or urethral manipulation without direct visualization 1
- Avoid repeated urethral dilations in urethral pain syndrome without stricture, as this may worsen fibrosis 6
- Always address partner treatment to prevent reinfection—failure to do so is a major cause of treatment failure 1, 3
- Do not extend antimicrobial duration in persistent symptoms without objective signs of ongoing urethritis 1
- Screen for and treat urine culture-positive infections before any urethral instrumentation to prevent urosepsis 1
- Consider chronic prostatitis/chronic pelvic pain syndrome in men with pain persisting >3 months despite treatment 1, 3
Special Populations
Pregnancy (third trimester):
- Azithromycin 1 g orally as a single dose is safe and effective 9
- Alternative: Erythromycin base 500 mg orally four times daily for 7 days 9
- Doxycycline and fluoroquinolones are contraindicated 9
