Vaginal Vault Suspension Explained

Vaginal vault suspension is a surgical procedure designed to address vaginal vault prolapse, a condition where the upper part of the vagina, known as the vaginal vault, descends or collapses. This often occurs after a hysterectomy, when the supportive structures of the vagina are no longer anchored by the uterus. Understanding this condition and its treatment is crucial for women experiencing its often debilitating symptoms.

What is Vaginal Vault Prolapse?

Vaginal vault prolapse happens when the top of the vagina, which was once supported by the cervix and uterus, loses its support and begins to fall downwards into the vaginal canal. This can happen months or even years after a hysterectomy, particularly if the vaginal cuff (the area where the cervix was removed and the vagina is stitched closed) is not adequately supported or if there are contributing factors such as chronic straining, heavy lifting, or obesity.

Grading Vaginal Prolapse

Doctors classify vaginal prolapse, including vault prolapse, into different grades based on its severity. This grading system helps determine the best course of treatment. The grades range from 0 to 4:

• Grade 0: No prolapse.
• Grade 1: The prolapsed organ (in this case, the vaginal vault) descends into the vagina but not to the introitus (vaginal opening).
• Grade 2: The prolapsed organ descends to the introitus.
• Grade 3: The prolapsed organ extends beyond the introitus but is still partially contained.
• Grade 4: Complete procidentia, where the entire vagina is outside the body.

Initially, mild to moderate forms of vaginal prolapse (typically Grades 1 and 2) are often treated with conservative options. These can include pelvic floor muscle exercises (often referred to as Kegel exercises) to strengthen the muscles that support the pelvic organs, and the use of vaginal pessaries. A pessary is a medical device inserted into the vagina to support the prolapsed organs and alleviate symptoms.

Who Needs Vaginal Vault Suspension?

Women who typically require vaginal vault suspension surgery are those experiencing a severe form of vaginal vault prolapse, usually corresponding to Grades 3 and 4, and suffering from significant symptoms. While mild prolapse might be asymptomatic or only cause minor discomfort, as it progresses, it can lead to a range of distressing issues:

• Feeling of heaviness in the vagina: A sensation of something falling out or a constant pressure within the pelvic area.
• Lower back pain: The displaced organs can put strain on the lower back muscles, leading to chronic pain.
• Problems with bladder or bowel control: This can manifest as urinary incontinence (leakage of urine), difficulty emptying the bladder, or constipation and faecal incontinence.
• Dyspareunia (painful intercourse): The altered anatomy can make sexual intercourse uncomfortable or painful.
• Pelvic pain: General discomfort or aching in the pelvic region.
• Bleeding ulcers over the bulge: In severe cases, the protruding vaginal tissue can become irritated, dry, and develop sores or ulcers, which may bleed.

When conservative measures fail to provide relief or when the prolapse is advanced and significantly impacting a woman's quality of life, surgical intervention like vaginal vault suspension becomes a necessary consideration.

How is Vaginal Vault Prolapse Repaired?

The description provided outlines a specific surgical technique for repairing vaginal vault prolapse, often involving the use of surgical mesh. This method is widely considered a criterion standard procedure by many surgeons due to its effectiveness in providing robust support.

The procedure typically involves the following steps:

1. Placement of Mesh: Special surgical mesh is used. This mesh is biocompatible and designed to provide strong, long-lasting support. The mesh is strategically passed through the pelvic tissues to create a supportive sling.
2. Tensioning and Suturing: The arms of the mesh are then carefully and gradually tensioned. This ensures that the vaginal vault is lifted back into its correct anatomical position without being overly tight. The mesh is then sutured (stitched) flat to create a stable support structure.
3. Vaginal Trimming and Closure: If necessary, the vaginal lining is minimally trimmed to remove any excess tissue, ensuring a neat closure. The surgeon will consider that the vaginal epithelium (lining) naturally contracts as it heals. The vagina is then closed securely with sutures.

This method aims to restore the natural support to the vaginal vault, preventing further descent and alleviating the associated symptoms. The use of mesh is favoured by many because it integrates with the body's tissues, creating a strong scaffold that can withstand the pressures of the pelvic organs.

Alternative Surgical Approaches

While the mesh technique described is common, it's important to note that other surgical approaches exist for vaginal vault prolapse repair. These may include:

• Sacrocolpopexy: This procedure involves using mesh to attach the vaginal vault to the sacrum (the bone at the base of the spine). It can be performed abdominally, laparoscopically, or robotically.
• Native Tissue Repairs: In some cases, surgeons may use the patient's own tissues (ligaments and fascia) to rebuild the support for the vaginal vault. This approach avoids the use of synthetic mesh.

The choice of surgical technique will depend on various factors, including the patient's overall health, the specific type and severity of the prolapse, and the surgeon's expertise and preference.

Recovery and Post-Operative Care

Following vaginal vault suspension surgery, recovery times can vary. Patients are typically advised to avoid strenuous activity, heavy lifting, and sexual intercourse for several weeks to allow the tissues to heal properly. It's essential to follow the surgeon's specific post-operative instructions to ensure the best possible outcome and to minimise the risk of complications or recurrence.

Frequently Asked Questions

Is vaginal vault suspension a permanent solution?

Vaginal vault suspension aims to provide a long-term solution for vaginal vault prolapse. However, the success rate can depend on various factors, including the surgical technique used, the patient's adherence to post-operative care, and individual health factors. While it significantly reduces the risk of recurrence, it doesn't eliminate it entirely for all patients.

What are the risks associated with vaginal vault suspension?

As with any surgical procedure, there are potential risks. These can include infection, bleeding, pain, injury to surrounding organs (bladder, bowel, or blood vessels), and mesh-related complications (though these are less common with modern techniques and careful placement). Your surgeon will discuss these risks in detail with you before the operation.

How long does the surgery take?

The duration of the surgery can vary depending on the specific technique used and the complexity of the prolapse. Typically, it can range from one to a few hours.

When can I resume normal activities after surgery?

Most women can return to light activities within a few weeks, but strenuous activities and heavy lifting should be avoided for at least 6-8 weeks, or as advised by your surgeon. It's crucial to listen to your body and gradually increase your activity levels.

In conclusion, vaginal vault suspension is a vital surgical option for women suffering from severe vaginal vault prolapse. By understanding the condition, its grading, and the surgical repair process, patients can make informed decisions about their treatment and work towards regaining their quality of life.
