PENILE & URETHRAL DISORDERS Flashcards
Two columns of tissue that run along side the penis that helps with erections
CORPUS CAVERNOSUM
⦁ Column of sponge-like tissue that runs along the front and ends at the glans
⦁ The urethra runs through here
CORPUS SPONGIOSUM
Runs through the spongiosum and helps evacuate semen and urine from the body
URETHRA
urethritis is more common in __________
females
CAUSES OF URETHRITIS
⦁ Gonorrhea ⦁ Chlamydia ⦁ HPV ⦁ Herpes Simplex ⦁ Idiopathic
most common causes of urethritis
⦁ Gonorrhea
⦁ Chlamydia
male symptoms of urethritis
⦁ dysuria
⦁ itching or burning at the meatus
⦁ hematuria / hematospermia
⦁ urethral discharge
female symptoms of urethritis
⦁ dysuria
⦁ frequency
⦁ suprapubic discomfort
⦁ discharge
DIAGNOSIS OF URETHRITIS
UA & CULTURE
NAAT (for chlamydia & gonorrhea)
TREATMENT OF URETHRITIS
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
A fibrotic band of tissue that renders the normal compliant urethral lumen inelastic
URETHRAL STRICTURE
Narrowing of the urethra with slowing of the urine
2 types of urethral strictures
anterior & posterior
anterior urethral stricture = from _______ to ______
from bulbar urethra to the meatus (from below the prostate to tip of penis)
posterior urethral stricture =
membranous & prostatic urethra (from bladder to prostate)
most common cause of urethral stricture in developed countries
idiopathic
causes of urethral stricture
o Idiopathic = most common cause of urethral stricture in developed countries
o Trauma
⦁ Anterior urethra = straddle injuries, blunt trauma, penetrating injuries
⦁ Posterior urethra = urethral disruption from pelvic fracture
o Iatrogenic
⦁ Catheterization - wrong size / traumatic
⦁ Surgical
o Infection
⦁ Gonococcal / Chlamydia (urethritis)
traumatic causes of anterior urethral stricture
saddle injuries, blunt trauma, penetrating injuries
traumatic causes of posterior urethral stricture
urethral disruption from pelvic fracture
iatrogenic causes of urethral stricture
cath - wrong size / traumatic
surgery
infectious causes off urethral stricture
gonococcal / chlamydia (urethritis)
SYMPTOMS OF URETHRAL STRICTURE
⦁ slow stream
⦁ decreased caliber
⦁ post-void dribbling
DIAGNOSIS OF URETHRAL STRICTURE
- Uroflowmetry = cylindrical device that measures speed of urination
- Ultrasound PVR
- Catheter
- Cystoscopy
- RUG - Retrograde Urethrogram = inject dye to see path/look for obstruction to bladder
cylindrical device that measures speed of urination
uroflowmetry
initial diagnostic test for urethral stricture
US PVR
urethral stricture treatment
- 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
Narrowing of the opening of the urethra at the tip of the penis
MEATAL STENOSIS
CAUSES OF MEATAL STENOSIS
⦁ swelling & irritation after newborn circumcision
⦁ idiopathic
⦁ failed “spadias” repairs
SYMPTOMS OF MEATAL STENOSIS
⦁ spraying of stream
⦁ bed wetting
⦁ dysuria
⦁ spraying of stream** (narrowing at meatal opening but not at the rest of the urethra, so pressure ends up spraying everywhere
***SPRAYING OF URINE
meatal stenosis
also hypospadias
DIAGNOSIS OF MEATAL STENOSIS
PHYSICAL EXAM
TREATMENT OF MEATAL STENOSIS
MEATONOMY
subincision underneath the glans
A meatotomy is a form of penile modification in which the underside of the glans is split
bed wetting
meatal stenosis
