Causes, Risk Factors, and Symptoms
Many causes contribute to POP, with gravity, aging, childbirth, and menopause at the top of the list.
“As people get older, their pelvic muscles and connective tissue get weaker, and the nerves don’t function as well,” Dr. Rabin said. Meanwhile, the body is losing estrogen, which affects how well the muscles contract and how easily the connective tissue can tear, she said.
With menopause, when baseline estrogen is lower, the tissue integrity is not as supportive as it should be and women are going to be at an increased risk of prolapse, Dr. Nwabuebo said.
POP has a range of risk factors:
- Increasing age, as muscle mass decreases and connective tissue hardens.
- Menopause.
- Vaginal delivery with complications, such as long second-stage labor, instrument-assisted delivery, multiple vaginal lacerations, and improperly repaired episiotomy.
- Multiple vaginal deliveries.
- Birthing large babies.
- Family history of pelvic organ prolapse (genetics can play a role in POP risk).
- Previous pelvic/abdominal surgery, including cesarean delivery and hysterectomy.
- Smoking (largely because of associated coughing).
- Chronic lung conditions that cause a lot of coughing.
- Chronic constipation or irritable bowel syndrome.
- Some types of high-impact activity, such as jogging or marathon running.
- Early menopause, for younger women.
- Repetitive heavy lifting in daily activities, such as occupational lifting (though not necessarily weight lifting as an exercise).
- Higher body mass index.
- Connective tissue disorders, such as joint hypermobility syndrome or Ehlers-Danlos syndrome.
Roger Dmochowski, MD, professor of urology and surgery at Vanderbilt University Medical Center, groups POP symptoms into two groups: anatomic and functional ones. A common anatomic symptom is bulging. “They’ll describe sitting on a ball, feeling like their bladder or something’s falling out, feeling a pressure or a heaviness,” Dr. Dmochowski said.
Functional symptoms can include vaginal dryness, vaginal irritation, painful intercourse, contact of the vaginal tissues with underclothes, and associated urinary symptoms, such as stress incontinence, urge incontinence, and incomplete emptying of the bladder. Dr. Dmochowski noted that women who report urinary incontinence may be at risk for being prescribed a medication without the necessary referral to a specialist for a full gynecologic evaluation.
Two other groups of functional symptoms include bowel-related disorders – primarily fecal incontinence and ongoing constipation – and pelvic pain or discomfort.
There can also be asymptomatic cases. “A lot of women have what we call silent prolapse,” Dr. Dmochowski said. That is, “they have some degree of loss of support to the bladder, vagina, or uterus, but they’re not symptomatic.” These women may be particularly good candidates for pelvic health physical therapy.
Screening and Diagnosis
Because many postmenopausal women stop seeing their ob.gyn, it’s often up to their primary care physician to determine whether their patients are experiencing POP symptoms.
“Women sometimes don’t bring this up with their doctor because they think there’s not enough time, or they’ll be laughed at, or their friends told them this is normal,” Dr. Rabin said. But primary care providers are really in a unique position to be able to ask the key symptom questions.
Dr. Rabin recommends a couple of questions to cover all the bases: “Do you leak urine when you cough or sneeze or on the way to the bathroom? Do you notice a bulge coming out of the vagina, or are you bothered by pelvic pressure?”
Dr. Dmochowski offered a single question that can open the conversation to more questions: “Are you bothered by any urinary or bowel or vaginal issues that we should talk about?” He also suggests asking how bothersome the symptoms are, which can help in directing treatment or prevention options. A physical exam can reveal signs of POP as well.
Diagnosis involves a detailed history, a comprehensive physical exam, and assessment with the Pelvic Organ Prolapse Quantification (POP-Q) tool. A urogynecologist can diagnose the type of POP – such as cystocele, rectocele, enterocele, uterine prolapse, or vaginal vault prolapse – and its grade (0-4).
Treatment: Physical Therapy, Pessary, and Surgery
No medications can treat prolapse, though some can treat downstream effects, such as hormonal vaginal creams for vaginal dryness and irritation, and medications for urinary incontinence. However, two mistakes PCPs can make are sending someone straight to surgery or prescribing them medication for symptoms without referring them for a diagnostic evaluation, Dr. Rabin said. “You have to have a diagnosis first to know what type of prolapse is there,” she said.
Because there can be long waiting lists for a urogynecologist or urologist, PCPs should also refer their patients to a pelvic health physical therapist (PT) who can help patients begin addressing the symptoms while they await a specialist who can diagnose them.
Though PT is often thought of as preventive, it’s also a conservative first-line intervention for prolapse, Dr. Nwabuebo said. Strong evidence shows pelvic floor muscle training from pelvic health PT can reduce symptoms of prolapse and reduce the severity by one grade in those with a grade 1 or 2 prolapse. Stage 3 is trickier, where PT may or may not be able to shift the symptom presentation, Dr. Nwabeubo said, and stage 4 is usually a surgical candidate.
“If you have a grade 4 prolapse, or the tissues are really visible outside the body, physical therapy and pelvic floor muscle training is not going to elevate that tissue back up into your body, but it can sometimes help with symptoms,” Dr. LaCross said.
The PT conducts a thorough pelvic muscle assessment, discusses lifestyle, and may teach breathing and bracing strategies for lifting, for example.
“A lot of what we’re talking about with pelvic floor therapy is lifestyle modifications,” Dr. Nwabuebo said. “If I have a patient with a history of chronic constipation, it doesn’t matter how much we do pelvic floor exercises; if we don’t manage the constipation issues by addressing their nutrition, then straining when using the bathroom will keep putting pressure on the pelvic floor.”
PTs can also recommend appropriate vaginal weights and dilators to help with pelvic floor strengthening and teach patients how to use them properly.
Even if women ultimately opt for surgery, PT prior to surgery can be beneficial. Dr. Rabin cited three reasons she recommends first-line PT: It may elevate the bladder enough to reduce stress incontinence and thicken the pelvic muscles, it can improve the effectiveness of a pessary or surgery if the woman chooses one of those options, and it can quiet bladder contractions, potentially obviating the need for pharmacologic treatment for overactive bladder.
The next nonsurgical option is a pessary, a device that fits into the vagina to provide support to the tissues displaced by prolapse. There’s a wide range of pessary types: some are short-term, worn only daily, or disposable, while others can be worn longer. Some women can self-insert and remove the pessary, and others may need a clinician to do so. Dr. Dmochowski recommends patients try a pessary to see if it benefits them. About a third of women will find them comfortable enough to wear regularly, but others will feel more sensitive to the pessary’s presence, he said.
One of the newest, most innovative pessary options for women is Gynethotics, which received Food and Drug Administration (FDA) clearance in March, as the first 3D-printed, customizable pessary capable of nearly 10 million configurations based on a person’s body.
Nearly all stage 4 prolapses and most of stage 3 prolapses can be addressed only through transvaginal or transabdominal surgery.
“We tell patients, if you can get 10 years out of your operation, you’re lucky,” Dr. Dmochowski said. A major reason for the short-lived durability is the poor quality of the tissue that needs to be pulled together. Serious complications resulting from use of polypropylene mesh during prolapse surgery led the FDA to halt sales of the devices and recommend discontinuing their use. However, one type of vaginal mesh is still considered safe to use in sacral colpopexy surgery.
Three things can shorten the durability of the surgery, Dr. Dmochowski said: heavy lifting, particularly anything over 30 pounds; chronic coughing, such as in those with chronic lung conditions; and chronic constipation.
Ms. Palm tried a pessary for her grade 3 prolapse with cystocele, rectocele, and enterocele but didn’t feel she had the time to use it regularly, so she opted for surgery. After a week on the couch recovering, she took it easy for another 12 weeks. Since then, she’s dedicated much of her time to educating and supporting women with POP and combating stigma associated with it. The APOPS website that she started has become a valuable resource for PCPs to send patients to, and the forum includes more 27,000 women from around the world.
“We encourage women to share what they’re experiencing. Tell your family, tell your friends, tell the people you work with about it,” Ms. Palm said. But many still feel uncomfortable speaking up, making PCPs’ role even more important.
