Endopelvic fascia
Meshwork of collagen, elastin and smooth muscle
Extends from the level of uterine artery to the fusion of the vagina and levator ani
Attached to uterus is parametrium – cardinal-uterosacral ligament complex
Attached to vagina is paracolpium – pubocervical and rectovaginal fasciae

Boat in Dock Analogy
Boat- pelvic organs
Water- levator muscles
Moorings- Endopelvic fascial ligaments
Problem is with the water or moorings or
both
Result is sinking of the boat
Really the boat itself is fine

PROLAPSE
Mutifactorial involving both neuromuscular and
endopelvic fascial damage
Relaxation of the tissues supporting the pelvic
organs may cause downward displacement of
one or more of these organs into the vagina,
which may result in their protrusion through the
vaginal introitus.

Cystocele
Main support of urethra and bladder is the pubo-vesical-cervical fascia
Essentially a hernia in the anterior vaginal wall due to weakness or defect in this fascia
Midline weakness allows bladder to descend causing central cystocele
Tearing of endopelvic fascial connections from lateral sulci to arcus tendinii causes lateral or displacement cystocele
Detachment of pubocervical fascia from pericervical ring causes a transverse or apical cystocele
Symptoms include pelvic pressure and bulge or mass in the vagina

Principles of reconstructive
pelvic surgery
Site-specific repair
Rebuild weakened endopelvic fascia, repair fascial tears, and reattach prolapsed tissues to stronger sites
Goal is a vagina of normal depth, width and axis
Denervation or muscle trauma cannot be corrected surgically
