Understanding Pelvic Organ Prolapse: Causes, Symptoms, and Treatment Options

Pelvic organ prolapse is one of the most common conditions I manage in my urogynecology practice. Despite affecting a significant proportion of women over their lifetime, it remains widely misunderstood. This article provides a clinician's perspective on what prolapse is, why it happens, and how it can be managed.

What is Pelvic Organ Prolapse?

Pelvic organ prolapse occurs when the pelvic floor muscles and connective tissues that support the pelvic organs (bladder, uterus, and rectum) become weakened or damaged. When this support fails, one or more of these organs can descend or bulge into the vaginal canal. The result is often a sensation of pressure, heaviness, or a visible or palpable bulge at the vaginal opening.

Prolapse is classified by which structure is descending: a cystocele involves the bladder, a rectocele involves the rectum, uterine prolapse involves the uterus, and vaginal vault prolapse occurs after hysterectomy when the top of the vagina loses support. Many patients have more than one compartment affected simultaneously.

What Causes Prolapse?

The most significant risk factor is vaginal delivery, particularly with prolonged pushing, large babies, or instrumental deliveries. However, prolapse is multifactorial. Other contributing factors include aging and menopause (which reduce tissue elasticity and strength), chronic straining from constipation or heavy lifting, obesity, chronic cough, connective tissue disorders, and prior pelvic surgery. Genetics also play a meaningful role — some women have inherently weaker connective tissue and are predisposed to prolapse even without other risk factors.

When to Seek Assessment

Not all prolapse requires treatment. Many women have mild prolapse detected on examination that causes no symptoms and requires no intervention. However, you should consider assessment if you experience: a persistent sensation of vaginal pressure or heaviness, a visible or palpable bulge at the vaginal opening, difficulty emptying the bladder or bowel, urinary symptoms such as frequency, urgency, or incontinence, or discomfort during physical activity or prolonged standing.

Treatment Options

Treatment is guided by the severity of symptoms, the degree of prolapse, the patient's goals, and their overall health. I always discuss the full range of options before recommending a specific approach.

Conservative Management

For many patients, non-surgical options are the first line of treatment. Pelvic floor physiotherapy with a trained physiotherapist can strengthen the muscles supporting the pelvic organs and significantly improve symptoms. A pessary — a removable silicone device inserted into the vagina — can provide mechanical support and is an effective option for women who prefer to avoid surgery or who are not surgical candidates. Vaginal estrogen therapy can help restore tissue thickness and elasticity in postmenopausal women. Lifestyle modifications including weight management, treating chronic cough, and managing constipation also play an important role.

Surgical Management

When conservative measures are insufficient or when the patient prefers definitive correction, surgery may be appropriate. Surgical options depend on the specific type and degree of prolapse, whether the patient wishes to preserve the uterus, and whether vaginal or abdominal (laparoscopic) approach is preferred. Common procedures include sacrocolpopexy (a laparoscopic procedure that uses a synthetic mesh to restore support to the vaginal apex), native tissue repairs using the patient's own ligaments and fascia, and various vaginal reconstructive procedures. In my practice, I emphasize minimally invasive approaches wherever possible, including laparoscopic sacrocolpopexy and laparoscopic-assisted vaginal procedures.

A Note on Vaginal Mesh

The topic of surgical mesh in prolapse repair has generated significant media attention and patient anxiety. It is important to distinguish between different types of mesh procedures. Transvaginal mesh kits for prolapse repair (now withdrawn from the market in many jurisdictions) had unacceptably high complication rates. However, sacrocolpopexy — which uses mesh placed through an abdominal (laparoscopic) approach — remains a well-established procedure with an excellent safety and durability profile. The distinction lies in the route of placement and the type of mesh used. I discuss these differences in detail with any patient considering mesh-based repair.

The Importance of Individualized Care

No two patients with prolapse are identical. Factors such as age, activity level, desire for future fertility, severity of symptoms, and personal preferences all influence the optimal treatment plan. My approach is to ensure that every patient understands their condition, the available options, and the expected outcomes and risks of each, so they can make a fully informed decision about their care.

If you are experiencing symptoms of pelvic organ prolapse, speak with your family physician about a referral to a urogynecologist for a comprehensive assessment.
