        3. Hepatitis B Testing (HBsAg)
    3. Symptoms of Prostatitis
      1. Consider Expressed Prostatic Secretion exam (rarely done)
      2. Do not perform Prostatic Massage in Acute Prostatitis
  5. Management: General Approach when STD unlikely
    1. Treat underlying condition
    2. Antibiotic selection based on likely source of infection
      1. Urinary Tract Infection
        1. Treat Urinary Tract Infections for 7 days in men
        2. If Prostatitis is considered a possible source, avoid Nitrofurantoin, fosfomycin and beta-lactams
      2. Acute Prostatitis
      3. Epididymitis
    3. Consider topical or systemic genitourinary irritants (see Dysuria and Dysuria in Men)
    4. Consider imaging and/or Consultation
      1. Persistent Hematuria without pyuria (e.g. CT Urogram, Cystoscopy)
      2. Urine Culture confirmed Urinary Tract Infection (e.g. post-void residual, renal/Bladder Ultrasound)
    5. Recurrent Urinary Tract Infection
      1. Consider BPH as cause of Recurrent UTI (related to Urethral obstruction)
      2. Consider Chronic Prostatitis as cause of Recurrent UTI with same organism
  6. Management: Empiric for sexually active patients with risk of STD
    1. Chlamydia management
      1. Doxycycline 100 mg twice daily for 7 days (preferred as of 2020) OR
      2. Azithromycin 1 g orally for 1 dose
    2. Gonorrhea management
      1. Ceftriaxone 500 mg IM/IV for 1 dose (1 gram IM/IV if weight > 150 kg, dose increased in 2020) OR
      2. Gentamicin 240 mg IM and Azithromycin 2 g orally for one dose OR
      3. Cefixime 800 mg orally once is an alternative but NOT recommended due to Antibiotic Resistance
    3. Recurrent symptoms with same partner (cover Trichomonas and Ureaplasma)
      1. Drug 1: Metronidazole 500 mg orally daily for 5 days AND
      2. Drug 2: Choose one of the following
