Urethral Prolapse: Excerpt from The 5-Minute Pediatric Consult

Stephen A. Zderic, MDMichele Clement, MD (4th Edition)

Urethral Prolapse - BASICS

Urethral Prolapse - description

• Circular eversion of the distal urethral mucosa through the external urethral meatus
• Classification of urethral prolapse:
  • I-Minimal of segmental inflammation
  • II-Circumferential prolapse with edema
  • III-Edematous mass protruding beyond the labia minora
  • IV-Severe hemorrhagic inflammation or necrosis and ulceration of the prolapse

Urethral Prolapse - epidemiology

• Prepubertal girls <10 years of age
• Preponderance among African American females (90–100% of patients in reported series)
• Patients above average for height and weight

Urethral Prolapse - risk factors

Urethral Prolapse - genetics

Predominance in African American females indicates a hereditary pattern.

Urethral Prolapse - etiology

Etiology unclear; proposed theories include:

• Poor adherence between smooth muscle layers of the urethra
• Estrogen deficiency
• Female circumcision

Urethral Prolapse - DIAGNOSIS

Urethral Prolapse - signs & symptoms

Urethral Prolapse - history

• 95% present with bleeding/bloody spotting in underwear
• 21% have dysuria, frequency
• Occasionally, a patient presents with urinary retention.
• Some are asymptomatic and detected only incidentally.

Urethral Prolapse - physical exam

• Circular (doughnut-shaped) protrusion of urethral meatus with a reddish-purple mass filling the introitus with the urethral meatus at the center
• Tissue appears inflamed and friable.
• To help distinguish between a urethral and vaginal mass, the vulva can be retracted downward and laterally.
• The knee–chest position with the child supine can help visualize the anatomy.

Urethral Prolapse - tests

Urethral Prolapse - imaging

• If the appearance is atypical for urethral prolapse, ultrasound may be used to rule out bladder tumor (sarcoma botryoides) or prolapsed ureterocele.
• Urethral prolapse with typical presentation requires no imaging.

Urethral Prolapse - differencial diagnosis

• Prolapsing ureterocele (or ectopic ureter, urethral polyp, bladder)
• Sarcoma botryoides
• Condyloma
• Hydrometrocolpos
• Periurethral abscess
• Trauma

Urethral Prolapse - TREATMENT

Urethral Prolapse - general measures

• Do not try to manually reduce the prolapsed tissue.
• Conservative—sitz baths followed by topical estrogen cream twice a day
  • Some suggest topical antibiotics
• Surgical—most typical surgical approach is excision of prolapsed segment over a urethral Foley catheter, suturing the proximal urethral margin to the adjacent vestibule.
