A cystocele, or bladder prolapse, happens when the front wall of the vagina weakens and the bladder bulges down into it. It can cause a vaginal bulge, pressure, slow urine flow, incomplete emptying and urinary infections. Doctors grade it by how far the wall descends, and treatment ranges from pelvic floor training and pessaries to surgical repair.
What is a cystocele?
The bladder rests on the front (anterior) wall of the vagina, which is supported by a layer of connective tissue sometimes called the pubocervical fascia, and by attachments to the side walls of the pelvis and the top of the vagina. When these supports stretch or tear, the bladder sags backward and downward, pushing the vaginal wall in front of it. The medical term "anterior vaginal wall prolapse" is often preferred, because the vaginal wall is what can be seen and measured.
A cystocele frequently occurs together with descent of the uterus or the top of the vagina. Recognizing this matters, because repairing the front wall alone when the apex has also lost support is a common reason for recurrence.
Common causes and risk factors
Cystocele develops for the same reasons as other types of pelvic organ prolapse. Major contributors include:
- Vaginal childbirth, which can stretch or detach the fascia and pelvic floor muscles
- Menopause and declining estrogen, which reduce tissue strength
- Repeated heavy lifting and chronic straining from constipation
- Long-term coughing from smoking or lung disease
- Obesity, which raises abdominal pressure
- Previous hysterectomy or pelvic surgery
- Inherited differences in collagen and connective tissue
Symptoms of bladder prolapse
Small cystoceles often cause no symptoms and may be found only on routine examination. When symptoms occur, they commonly include:
- A soft bulge at or beyond the vaginal opening, often more noticeable after standing or straining
- Pressure or fullness in the vagina
- A weak or interrupted urine stream and a feeling of incomplete emptying
- Needing to press on the bulge or change position to empty the bladder, sometimes called splinting
- Frequent urination, urgency or recurrent urinary tract infections
- Leakage with coughing, laughing or exercise
Interestingly, some women with a large cystocele have no leakage because the bulge kinks the urethra. When the prolapse is repaired, this hidden or occult stress incontinence can appear. For this reason, many specialists test bladder function with the prolapse reduced before surgery.
Cystocele grades and POP-Q stages explained
The traditional grading system
Older descriptions use grades. Grade 1 means the bladder drops only a short way into the vagina. Grade 2 means it reaches the vaginal opening. Grade 3 means it bulges outside the opening. Some systems add a grade 4 for complete eversion.
The POP-Q system
Most specialists now use the Pelvic Organ Prolapse Quantification system, introduced in 1996, which measures specific points in centimeters relative to the hymen while the patient strains. It produces stages from 0 to IV. Stage 0 means no prolapse. Stage I means the most descended part stays more than 1 cm above the hymen. Stage II means it lies within 1 cm above or below the hymen. Stage III means it extends more than 1 cm beyond the hymen but not completely. Stage IV means complete eversion. POP-Q is more precise and allows changes over time to be tracked reliably.
It is worth knowing that stage does not always match bother. Symptoms usually become more noticeable once the bulge reaches the vaginal opening, but treatment decisions are based on how much the prolapse affects your life.
How cystocele is diagnosed
Diagnosis is mainly clinical. The usual assessment includes:
- A detailed history of bladder, bowel, sexual and bulge symptoms.
- A pelvic examination lying down and sometimes standing, while coughing and bearing down.
- POP-Q measurement of all vaginal compartments, not only the front wall.
- A urine test to rule out infection.
- Measurement of the urine left in the bladder after voiding, usually by ultrasound.
- Urodynamic testing in selected women, particularly before surgery or when leakage is complex.
Non-surgical treatment options
Treatment is not needed for a cystocele that causes no bother. For symptomatic prolapse, conservative options come first for many women.
Pelvic floor muscle training
Supervised training with a pelvic health physiotherapist can reduce bulge symptoms and improve bladder control, particularly in mild to moderate prolapse. It works best when continued long-term.
Vaginal pessaries
A pessary is a silicone device placed in the vagina to support the bladder and other organs. Ring pessaries suit many women with cystocele. Pessaries require periodic cleaning or review, and side effects can include discharge, irritation and, less often, erosion of the vaginal wall.
Lifestyle and hormonal measures
Weight loss, treating constipation, stopping smoking and avoiding heavy lifting reduce strain. In postmenopausal women, vaginal estrogen can improve tissue quality and pessary comfort.
Surgical repair of cystocele
Surgery is considered when symptoms are bothersome and conservative measures have not helped or are not wanted. The most common operation is anterior colporrhaphy, in which the surgeon opens the front vaginal wall, plicates the supporting tissue with stitches and trims excess lining. If the top of the vagina or uterus has also descended, an apical suspension is usually added.
Synthetic mesh was once widely used to reinforce front wall repairs. Because of concerns about complications such as erosion and pain, the US FDA ordered manufacturers to stop selling transvaginal mesh products for prolapse repair in 2019. Native tissue repair remains the standard vaginal approach in most settings. Recovery typically involves avoiding heavy lifting and intercourse for about six weeks. Recurrence is possible, especially in the front compartment.
Frequently asked questions
Can a cystocele heal on its own?
The tissue damage does not usually reverse by itself, but symptoms of a mild cystocele can improve with pelvic floor training and lifestyle changes. Some cystoceles remain stable for many years. Regular review helps track any change.
Is a cystocele dangerous?
It is rarely dangerous, but it can significantly affect quality of life. Problems such as being unable to empty the bladder, recurrent infections or kidney swelling from obstruction in severe cases need prompt assessment.
What is the difference between a cystocele and a urethrocele?
A cystocele involves the bladder bulging into the upper part of the front vaginal wall. A urethrocele involves the urethra in the lower part near the opening. The two often occur together and are sometimes called a cystourethrocele.
Will surgery fix my urinary leakage?
Prolapse repair improves emptying problems in many women, but it does not reliably cure stress incontinence and may even unmask it. If leakage is present or likely, your surgeon may discuss a separate continence procedure. Testing before surgery helps plan this.
Can I have sex with a cystocele?
Yes. Sex is not harmful to a cystocele, although some women notice discomfort or embarrassment about the bulge. A pessary may need to be removed or may stay in during sex depending on the type.
