9
Q

A

UA & CULTURE

NAAT (for chlamydia & gonorrhea)

10
Q

TREATMENT OF URETHRITIS

A

Suspected gonococcal vs non-gonococcal.
intramuscular dose of ceftriaxone(250 mg)
Azithromycin 1g PO single dose
Doxycycline 100mg bid x 7 days
Alternatives
Erythromycin 500mg PO qid x 7 days
Levofloxacin/Cipro 500mg PO once daily x 7 days

So Rocephin for gonococcal
Azithro or Doxy for non-gonococcal

fluoroquinolones are coming out of favor though due to resistance

  • Treat partner
  • Educate about condom use
  • Avoid irritants
  • NSAIDS

***Bring pt back to re-test to assure pt is cured

11

uroflowmetry

24

US PVR

25
Q

urethral stricture treatment

A
  • urethral dilation
  • DVIU
  • urethroplasty

⦁ urethral dilation (with calibers - insert larger & larger calibers through urethra - pt will need to continue with self-calibration)

⦁ DVIU = direct vision internal urethrotomy - use camera through urethra and carve out tissue in urethra

⦁ Urethroplasty = re-direct urethra to perineum - now has to sit down to pee as urethra is no longer coming out of penis. Increased risk of infection due to proximity to anus. This is the permanent long-term fix for urethral stricture
