Management of Male Patients with Persistent Urethritis Symptoms

Diagnostic Approach

The presence of mucopurulent or purulent urethral discharge, or a positive leukocyte esterase test on first-void urine, or ≥10 WBC per high-power field on microscopic examination of first-void urine sediment indicates the need for further testing 1, 2
If objective signs of urethritis persist with a negative urethral swab, obtaining first-void urine for T. vaginalis PCR or culture is recommended 3
Consideration of semen specimen for PCR or culture can detect additional cases missed by urine alone 3

For persistent/recurrent urethritis with negative Trichomonas testing, treatment with metronidazole 2g orally in a single dose (or tinidazole 2g single dose) PLUS azithromycin 1g orally in a single dose is recommended if not used for the initial episode 1, 2
This combination addresses T. vaginalis (which may still be present despite negative testing) and Mycoplasma genitalium, a common cause of persistent urethritis 1, 2
Partners should receive treatment effective against both Chlamydia and Trichomonas regardless of testing results 1, 2
Both patient and partners must abstain from sexual intercourse for 7 days after treatment initiation and until symptoms resolve 2

Retreatment should not be based on symptoms alone without objective signs of urethritis, as this leads to unnecessary antibiotic exposure 1, 2
