Objectives
• To define pelvic organ prolapse
• Recognize pelvic anatomy
• Determine the Pathophysiology
• Discuss the predisposing factors
• Understand the grading systems
• Be aware of the options of management
Pelvic Organ Prolapse
• Is the descent of the pelvic organs as a result of the loss of muscular and fascial structural support .
Anatomic Supports
• Muscular : Levator Ani (Pelvic Floor Ms.)
• Ligaments : Uterosacral-Cardinal Complex
• Fascial : Endopelvic (Pubocervical & Rectovaginal)
Levator Ani
• Major structure of pelvic floor
• Anterior/posterior orientation
• Perforated by urogenital hiatus
• Consists of : Pubococcygeus
Iliococygeus
Puborectalis
Coccygeus
Endopelvic Fascia
• Fibromuscular layer
• Local condensations are ligaments
• Principal ligaments are Uterosacral
Cardinal
• Pubocervical and Rectovaginal Fascia important in specific surgical correction
Pathophysiology
• Direct Trauma to pelvic soft tissues
• Neurological injury
• Connective tissue disorders
Predisposing Factors
• Hereditary (genetic) predisposition
• Race: White > Black > Asian
• Pregnancy and Vaginal Childbirth
• Age and Menopause
• Raised intra-abdominal pressure (e.g.: obesity, cough, constipation, lifting, etc)
• Iatrogenic: surgical procedure
Types of Pelvic Organ Prolaopse
1. Urethra
2. Bladder
3. Uterus/ Vaginal Vault
4. Small Bowel
5. Rectum
6. Perineum
Compartments
• Anterior : Cystocele
Urethrocele
• Middle : Uterine prolapse
Enterocele/vault prolapse
• Posterior : Rectocele
Rectal prolapse
Classification of Prolapse
• Baden Walker (1972)
• Each site graded from 1 – 4
• POPQ: quantifies using specific points
• Measured relation to the hymenal ring
• More widely used
Symptoms of Prolapse
• Pelvic pressure
• Pelvic pain
• Feeling of a “lump”
• Back pain
• Urinary dysfunction
• Bowel dysfunction
Complications of Prolapse
• Bleeding
• Infection
• Recurrent UTI’s
• Urinary obstruction
• Renal failure
Associated conditions
• Urinary Incontinence : Stress
Urge
Mixed
• Fecal Incontinence : sphincter injury
Options of Management
• No Treatment ( pelvic floor exercise)
• Conservative: such as
Physiotherapy or Pessary
• Surgical Treatment
Aims of prolapse surgery
• Alleviate symptoms
• Restore normal anatomy
• Restore normal visceral function
• Avoid new bladder or bowel symptoms
• Preserve sexual function
• Avoid surgical complications

Conclusions
• Pelvic organ prolapse is common• Results from injury to soft tissue and nerves• Childbirth most significant association• Treatment requires understanding of anatomic
relationships• Treated with a combination of physio/pessary
and often complex surgery
