Management of Ureaplasma Species Detected in Urine
Do not treat Ureaplasma species detected in urine unless the patient has documented symptoms of urethritis (urethral discharge, dysuria, urethral pruritus) or objective signs of urethritis (≥5 polymorphonuclear leukocytes per high-power field on urethral smear). 1, 2
Critical First Step: Determine If Treatment Is Indicated
The pathogenic role of Ureaplasma species remains debated, with recent evidence suggesting only U. urealyticum (not U. parvum) causes true urethritis. 1, 3, 2
Do NOT treat if:
- Patient is asymptomatic (asymptomatic bacteriuria) 1, 2
- Only U. parvum is identified without symptoms 3, 4
- No objective signs of urethritis are present 2
DO treat if:
- Symptomatic urethritis with U. urealyticum confirmed 1, 2
- Patient undergoing traumatic urinary tract procedures (transurethral resection, cystoscopy breaching mucosa) 1, 2
Exclude Other Pathogens First
Before attributing urethritis to Ureaplasma, perform nucleic acid amplification testing (NAAT) on first-void urine or urethral smear to exclude: 1
First-Line Treatment for Symptomatic U. urealyticum
Doxycycline 100 mg orally twice daily for 7 days is the preferred first-line treatment, achieving 91% susceptibility rates. 3, 2, 5
Alternative Regimens (When Doxycycline Contraindicated or Compliance Concerns)
- Azithromycin 1.0-1.5 g orally as single dose (71% susceptibility) 1, 3, 2, 5
- Levofloxacin 500 mg orally once daily for 7 days 2
- Ofloxacin 200 mg orally twice daily for 7 days 1
Critical caveat: Do not use fluoroquinolones empirically if the patient is from a urology department or has used fluoroquinolones in the last 6 months due to high resistance rates. 1, 2
Treatment Duration Considerations
Management of Treatment Failure
If symptoms persist after doxycycline: 3, 2
- First, confirm objective signs of urethritis still present (do not retreat based on symptoms alone) 2, 4
- If non-compliance or partner re-exposure occurred: Re-treat with initial doxycycline regimen 3
- After documented doxycycline failure: Azithromycin 500 mg on day 1, then 250 mg daily for 4 days 1, 3
- After azithromycin failure: Moxifloxacin 400 mg orally once daily for 7-14 days (for macrolide-resistant strains) 1, 2, 4
Partner Management (Essential to Prevent Reinfection)
All sexual partners must be evaluated and treated while maintaining patient confidentiality. 1, 3, 2
- For symptomatic patients: Treat partners with last sexual contact within 30 days of symptom onset 2, 4
- For asymptomatic patients: Treat partners with last sexual contact within 60 days of diagnosis 2, 4
- Both patient and partners must abstain from sexual intercourse for 7 days after single-dose therapy or until completion of 7-day regimen 3
Follow-Up Strategy
- Test-of-cure is NOT routinely recommended after doxycycline or azithromycin unless symptoms persist or reinfection is suspected 3, 4
- If performed: Test no earlier than 3 weeks after treatment completion 3
- Return for evaluation only if symptoms persist or recur 4
Common Pitfalls to Avoid
- Treating asymptomatic Ureaplasma detection: This represents commensal colonization, not infection, and treatment may select for antimicrobial resistance. 1, 2
- Treating U. parvum: Its pathogenic role is questionable; only U. urealyticum is considered a true urethritis pathogen. 1, 3
- Failing to treat sexual partners: This is the most common cause of treatment failure and recurrence. 2, 6
- Retreating based on persistent symptoms alone without documented urethritis: Confirm objective signs before additional antimicrobial therapy. 2, 4
- Using fluoroquinolones in high-risk populations: Avoid in patients from urology departments or recent fluoroquinolone users. 1, 2
