Pelvic bladder
Contributor(s): Kyle Mathews, Richard Walker
Introduction
- Cause: embryological anomaly.
- Signs: urinary incontinence.
- Diagnosis: radiography.
- Treatment: medical management or surgical correction.
- Prognosis: guarded for full resolution of signs.
Pathogenesis
Etiology
- Embryological anomaly.
- Cause unknown.
Pathophysiology
- Anatomy established as neonate but signs may not become evident until adult life.
- Bladder remains at pelvic level instead of migrating cranially into abdomen.
- 'Pear-shaped' bladder with rounded urethral vesical junction.
- Bladder neck is within the pelvic canal.
Pathophysiology
- A component of urethral sphincter mechanism incompetence in many incontinent bitches.
- Bladder remains at pelvic level instead of migrating cranially into abdomen.
- Effect on sphincter mechanism is not known.
