pelvic organ prolapse Flashcards
(44 cards)
What is pelvic organ prolapse (POP)?
Descent of endopelvic organs through the urogenital hiatus due to failure of pelvic support structures.
Which organs are commonly involved in POP?
Uterus, urinary bladder, rectum, or vaginal vault.
Which population is POP more frequent in?
White Caucasian, post-menopausal, multiparous women over 50 years old.
What is the lifetime risk of developing POP for women?
0.11
According to the WHI study, what was the POP prevalence in women over 60?
41% in those without hysterectomy, 38% with hysterectomy.
How is the vaginal position maintained in healthy individuals?
The vagina is pressed against the muscular plane preventing prolapse during increased abdominal pressure.
What causes POP when muscular tone is reduced?
Abdominal pressure can cause prolapse and organ exteriorization.
List acquired risk factors for POP.
Obesity, childbirth, constipation, chronic bronchitis, menopause, pelvic surgery.
List inherited risk factors for POP.
Connective tissue diseases, increased elastase, reduced elastin, altered collagen turnover.
What is the role of the pelvic diaphragm?
Supports pelvic organs and maintains lower urinary, reproductive, and digestive system containment.
Which muscles form the levator ani?
Pubococcygeus, iliococcygeus, and ischiococcygeus.
What stabilizes the urethra anteriorly?
Pubo-urethral ligament.
What stabilizes the bladder laterally and inferiorly?
Urethropelvic ligaments and pubo-cervical fascia.
Which ligaments support the uterus and vaginal vault?
Cardinal and uterosacral ligaments.
What is DeLancey’s Level 1 support?
Uterosacral and cardinal ligaments support uterus and vaginal vault.
What is DeLancey’s Level 2 support?
Arcus tendinous and vescicopelvic ligament support the vagina.
What is DeLancey’s Level 3 support?
Perineal body, pubo-urethral and urethropelvic ligaments, and perineal muscles.
What is a cystocele?
Prolapse of the bladder into the anterior vaginal wall.
What is a rectocele?
Prolapse of the rectum into the posterior vaginal wall.
What is an enterocele?
Prolapse of the peritoneal cul-de-sac with ileal segments.
What is a hysterocele?
Uterine prolapse.
Describe Grade 0 in Baden-Walker system.
Normal physiological situation.
What is Grade I in POP?
POP reaches halfway to hymeneal ring on straining.
What is Grade II POP?
POP reaches the hymeneal ring on straining.
