Basics
Description
- Pelvic organ prolapse occurs when the normal supports of the pelvic organs fail, allowing the pelvic organs to "prolapse " or protrude into the vagina.
- Pelvic organ prolapse can be further defined by which vaginal compartment has prolapsed:
- Apical or upper vagina
- Anterior vaginal wall
- Cystocele
- Paravaginal
- Urethrocele
- Posterior vaginal wall
- Enterocele
- Rectocele
- Perineal deficiency
Epidemiology
- In general, it is difficult to study given the long latency period.
- The prevalence of pelvic organ prolapse increases with age; therefore, the changing demographics of the population will result in more affected women.
- The direct cost of surgery for prolapse is estimated to be greater than $1 billion/year.
- Lifetime risk for undergoing surgery for prolapse or incontinence is 11% in the US.
Incidence
- Anterior vaginal prolapse ( "bladder prolapse, " "cystocele " ): 9.3 cases per 100 women per year
- Posterior vaginal prolapse ( "rectocele " ): 5.7 cases per 100 women per year
- Uterine prolapse: 1.5 cases per 100 women per year
Prevalence
- Anterior vaginal prolapse: 24 " 34%
- Posterior vaginal prolapse: 13 " 18%
- Uterine prolapse: 4 " 14%
Risk Factors
- Predisposing factors (congenital)
- Neurologic, connective tissue, musculoskeletal
- Genetic
- Inciting factors (acquired)
- Childbirth
- Pelvic surgery
- Neurologic injury
- Promoting factors
- Obesity
- Smoking
- Chronic straining, constipation
- Frequent heavy lifting
- Menopause
- Decompensating factors
- Aging
- Poor mobility
- Environment
- Medication
Pathophysiology
Weakening or injury of pelvic supportive structures (connective tissue, pelvic floor muscles, and nerves) results in prolapse of pelvic organs.
Etiology
- Likely multifactorial
- Childbirth
- Labor and delivery may result in direct damage to connective tissue supports and muscles (disruption).
- Indirect damage may result in injury to nerves and muscles (ischemia, compression, stretching).
- Pudendal nerve latency has been shown to be prolonged after delivery, although this recovers over time.
- Connective tissue disorders
- Ehlers " Danlos, Marfan syndrome
- Pelvic neuropathy
- Chronic constipation, straining, and vaginal childbirth may cause chronic stretching and injury to pudendal nerve.
- Congenital disorders
- Spina bifida
- Bladder exstrophy
- Postoperative effects
- Pelvic surgery may disrupt innervation to pelvic supportive tissues.
- Obesity
- Chronic cough
- Smoking
Associated Conditions
- Urinary incontinence
- Fecal incontinence
- Depression
Diagnosis
History
- Review of systems including (1)[C]:
- Presence, severity, duration, and bother of prolapse symptoms
- Concurrent urinary, bowel, neurologic, or sexual function concerns
- Poor stream, hesitance, straining to void, incomplete emptying, recurrent urinary tract infection (UTI), splinting (need to reduce prolapse to urinate/defecate)
- Past medical history including (1)[C]:
- Prior conservative medical treatment
- Pessary trial
- Physical therapy, Kegel exercises
- Coexisting diseases (as listed under "Risk Factors " ) such as constipation
- Physical impairment
- Patients with limited mobility, dexterity, or vision may have different needs.
- Past surgical history including (1)[C]:
- Previous prolapse or anti-incontinence surgery, pelvic surgery
- Patient medication (1)[C]
- Obstetric and menstrual history (1)[C]
- Social history (1)[C]:
- Other:
- Patient goals and expectations (1)[C]
- Support symptoms/care-givers (1)[C]
- Cognitive function (1)[C]
Physical Exam
- Pelvic examination should:
- Define severity of maximum anatomic support defect (1)[C]
- Assess pelvic muscle function (1)[C]
- Determine if epithelial or mucosal ulceration is present (1 " 2)[C]
- Examination of pelvic support and all vaginal areas should be done with patient resting and with patient straining with Valsalva maneuver (2 " 4)[C].
- Examination of each compartment with split speculum on straining (2 " 3)[C]
- Cervix or vaginal cuff
- Anterior vaginal wall
- Posterior vaginal wall
- Genital hiatus (length of vaginal opening)
- Perineal body
- Vulvar or vaginal atrophy (1)[C]
- Cough stress test to rule out stress incontinence (2)[C]
- Bimanual exam (2)[C]
- Recto-vaginal exam (2)[C]
- Poor sphincter tone
- Anal sphincter defect
- Neurologic examination
- Anal wink reflex (1)[C]
- Pelvic muscle strength (2)[C]
- Sensation (1)[C]
Tests
Lab
Urinalysis or urine culture to rule out infection (2)[C], (3)[C]
Imaging
- Usually not necessary (1 " 3)[C]
- Consider upper urinary tract imaging if prolapse is beyond the hymen and the patient declines pessary or surgery (1)[C]
- Anal manometry or defecography may be considered for women with defecatory symptoms (3)[C].
Surgery
- Reduce prolapse to evaluate occult (masked, latent, potential) stress incontinence; urodynamic evaluation or cough stress test may be used (2 " 4)[C]
- Post-void residual (1 " 3)[C]
Differential Diagnosis
- Rectal prolapse
- Pelvic mass
Treatment
Additional Treatment
General Measures
- Many patients with prolapse are asymptomatic and seek only reassurance (4)[C].
- Treatment goal is to minimize the impact of condition or achieve a cure (2)[C].
- Treatment strategy depends on the severity of the symptoms, associated pelvic floor conditions, prior surgery, as well as the patient 's general health, activity level, and informed decision (2)[C].
Observation
- Patients with mild asymptomatic prolapse may be monitored with annual exams (3 " 4)[C].
- Asymptomatic patients with severe prolapse should be examined every 3 months to reassess the risks and benefits of observation (2)[C].
- Asymptomatic patients with obstructed urination/defecation, unresponsive vaginal erosions, or hydronephrosis from ureteral kinking should be treated (3)[C].
Nonsurgical management
- Pelvic floor muscle training
- Reduce the symptoms of prolapse (1)[B]
- Prevent or slow deterioration of anterior prolapse (1)[B]
- Pessary
- Should be discussed with all symptomatic women (4)[B]
- Can be fitted in most women regardless of prolapse stage (4)[A]
- Successful fitting less likely with vaginal length less than 7 cm, or vaginal introitus wider than 4 finger-breadths
- Protrusion symptoms may improve with successful "fit " (1)[B].
- Correct fit includes:
- Symptom resolution (2)[C]
- Pessary should be comfortable, and stay in place with Valsalva (2)[C].
- Patients should be able to void with the pessary in place prior to leaving clinic (3)[C].
- No clear consensus on frequency of follow-up
- Initial follow-up 2 " 3 weeks (2)[C]
- Patients able to remove/replace pessary need less frequent follow-up than those who cannot (2 " 3)[C].
- Follow-up recommendations range from 1 to 6 months, but regular follow-up is mandatory (1 " 3)[C].
- At follow-up visits:
- Pessary is removed and inspected (2)[C].
- Vaginal walls are inspected for evidence of abrasions or ulcerations from pessary (may need a different size) (2)[C].
- Vaginal atrophy or erosions treated with topical estrogen cream (1 " 3)[C]
- Patients who will not follow up are not candidates for pessaries as prolonged neglect may result in the pessary becoming impacted in the vagina or erosion of pessary into bladder or rectum (2 " 3)[C].
Issues for Referral
- Unsuccessful conservative management
- Visible prolapse (beyond hymen)
- Significant symptoms
- Recurrent UTIs
Surgery
- Type and extent of repair will depend on precise defects, patient 's desires and expectations, associated pelvic floor disorders (incontinence), and the patient 's age, medical status, and comorbidities.
- The only symptom specific to prolapse is vaginal bulge or protrusion. Other symptoms may or may not be related to prolapse (4)[A].
- Obliterative (closure of vagina)
- Reserved for women who do not desire future vaginal intercourse (1)[B]
- Elderly, medically compromised (3)[C]
- Shorter operative time, decreased perioperative morbidity, low risk of recurrence (3)[C]
- Reconstructive
- Vaginal prolapse repair should be performed with compartment-specific repairs depending on what is prolapsed and symptomatic (2)[C].
- Apical prolapse requires re-suspending the vaginal apex to nearby ligaments.
- Apical prolapse may be repaired via a vaginal, abdominal, laparoscopic, or robotic approach.
- Round ligament suspension is not effective for uterine or vaginal prolapse (4)[B].
- Anterior vaginal prolapse can be repaired with either a vaginal approach (cystocele repair) or abdominal/laparoscopic repair (paravaginal) (2)[C].
- Posterior vaginal prolapse (rectocele) repair should be performed via a transvaginal and not a transanal approach (4)[B].
- Vaginal mesh should be used with caution because of potential complications such as erosion, infection, pain, and dyspareunia (3)[C].
- FDA safety communication issued in 2011 for transvaginal mesh use for pelvic organ prolapse.
- Clinicians should discuss the risks and benefits of concurrent anti-incontinence procedures for asymptomatic women (4)[C].
- Continent patients identified with stress urinary incontinence preoperatively during prolapse correction are at increased risk of postoperative incontinence if uncorrected (4)[A].
Ongoing Care
Prognosis
Prognosis is variable depending on type of repair.
Complications
Severe prolapse left untreated may result in urinary retention, frequent UTIs, pyelonephritis, vaginal ulcerations, erosions, and infections.
