Pelvic Organ Prolapse Flashcards
What does POP stand for?
Pelvic organ prolapse
What is prolapse?
Prolapse = protrusion of an organ or structure beyond its normal anatomical confines
What is female POP?
Female POP = refers to the descent of the pelvic organ towards or through the vagina
What are the 3 layers of the pelvic floor?
-
Endo-pelvic fascia
- Network of fibro-muscular connective tissue, includes
- Uteroscral ligaments
- Medially – to uterus, cervix, lateral vaginal fornices and pubocervical and rectovaginal fascia
- Laterally – to sacrum and fascia overlying the piriforms muscle
- Easily palpated by down traction of cervix
- Tends to break medially
- Pubocervical fascia
- Provides the main support of anterior vaginal wall
- Centrally – merge with the base of cardinal ligaments and cervix
- Laterally – arcus tendinous fascia pelvis
- Distally – urogenital diaphragm
- Tends to break at lateral attachments or immediately in front of cervix
- Rectovaginal fascia
- Made from elastic tissue
- Centrally – merge with the base of cardinal/uterosacral ligaments and peritoneum
- Laterally – fuses with fascia over levator ani
- Distally – firmly to the perineal body
- Tends to break centrally, if upper defect is called enterocele, if lower defect is called perineal body descent and rectocele
-
Pelvic diaphragm
- Layer of striated muscles with its fascial coverings, includes levator ani and occygeus
-
Urogenital diaphragm
- Superficial and deep transverse perineal muscles with fascial coverings
What composes the endo-pelvic fascia?
- Network of fibro-muscular connective tissue, includes
-
Uteroscral ligaments
- Medially – to uterus, cervix, lateral vaginal fornices and pubocervical and rectovaginal fascia
- Laterally – to sacrum and fascia overlying the piriforms muscle
- Easily palpated by down traction of cervix
- Tends to break medially
-
Pubocervical fascia
- Provides the main support of anterior vaginal wall
- Centrally – merge with the base of cardinal ligaments and cervix
- Laterally – arcus tendinous fascia pelvis
- Distally – urogenital diaphragm
- Tends to break at lateral attachments or immediately in front of cervix
-
Rectovaginal fascia
- Made from elastic tissue
- Centrally – merge with the base of cardinal/uterosacral ligaments and peritoneum
- Laterally – fuses with fascia over levator ani
- Distally – firmly to the perineal body
- Tends to break centrally, if upper defect is called enterocele, if lower defect is called perineal body descent and rectocele
What are the attachments of the uterosacral ligaments?
- Medially – to uterus, cervix, lateral vaginal fornices and pubocervical and rectovaginal fascia
- Laterally – to sacrum and fascia overlying the piriforms muscle
Where does the uterosacral ligaments tend to break?
Medially
What is the function of the pubocervical fascia?
- Provides the main support of anterior vaginal wall
What are the attachments of the pubocervical fascia?
- Centrally – merge with the base of cardinal ligaments and cervix
- Laterally – arcus tendinous fascia pelvis
- Distally – urogenital diaphragm
Where does the pubocervical fascia tend to break?
- Tends to break at lateral attachments or immediately in front of cervix
What are the attachments of the rectovaginal fascia?
- Centrally – merge with the base of cardinal/uterosacral ligaments and peritoneum
- Laterally – fuses with fascia over levator ani
- Distally – firmly to the perineal body
Where does the rectovaginal fascia tend to break?
- Tends to break centrally, if upper defect is called enterocele, if lower defect is called perineal body descent and rectocele
What are the 2 kinds of defects of the rectovaginal fascia?
- Tends to break centrally, if upper defect is called enterocele, if lower defect is called perineal body descent and rectocele
What is the pelvic diaphragm composed of?
- Layer of striated muscles with its fascial coverings, includes levator ani and occygeus
What is the urogenital diaphragm composed of?
- Superficial and deep transverse perineal muscles with fascial coverings
