Bladder Prolapse (Cystocele) — When the Bladder Drops Into the Vaginal Canal
A cystocele — commonly called a 'dropped bladder' or bladder prolapse — occurs when the supportive tissue between the bladder and the vaginal wall weakens or tears, allowing the bladder to bulge down into the vaginal canal. It is a form of pelvic organ prolapse (POP), the collective term for descent of the pelvic organs — bladder, uterus, rectum, or small bowel — through a weakened pelvic floor. Cystocele is the most common form of pelvic organ prolapse, affecting approximately 30 to 40% of women who have had vaginal deliveries, with increasing prevalence after menopause as oestrogen withdrawal further weakens pelvic support.
Cystocele causes a spectrum of symptoms — from a mild sensation of pelvic pressure or a soft bulge at the vaginal opening, to significant voiding difficulty (the prolapsed bladder creates a kink in the urethra, causing incomplete emptying), recurrent urinary tract infections (from residual urine in the prolapsed bladder segment), and urinary incontinence. Many women tolerate a cystocele for years without seeking help, incorrectly believing that it is an inevitable consequence of childbirth that cannot be treated.
Grading — the POP-Q system
| Grade | Definition | Symptoms typically present |
|---|---|---|
| Grade I | Bladder prolapse into the upper vagina only — does not reach the vaginal opening · Mild | Often asymptomatic or mild pelvic pressure. Incidental finding on gynaecological examination. |
| Grade II | Bladder prolapse reaches the vaginal opening (introitus) — may be visible as a bulge at the vaginal opening on straining | Pelvic heaviness · Bulge sensation · Mild voiding difficulty · Often worse at end of day after prolonged standing. |
| Grade III | Bladder prolapse extends beyond the vaginal opening at rest or on straining | Visible and palpable bulge outside the vaginal opening · Significant voiding difficulty and incomplete emptying · May need to manually reduce the prolapse (push the bulge back in) to void. |
| Grade IV | Complete prolapse — the entire anterior vaginal wall and bladder is outside the vaginal opening | Severe — may cause urinary retention from kinking of the urethra · Skin irritation and ulceration of exposed vaginal wall. |
Symptoms
How a cystocele presents
A bulge or pressure in the vagina — the classic symptom. Often described as 'something coming down' or 'like sitting on a ball.' Worse after prolonged standing, lifting, or at end of day. Improves on lying down.
Incomplete bladder emptying — the prolapsed bladder creates a pouch that does not empty during voiding. Patients may need to change position (stand up, lean back, or manually reduce the prolapse) to void fully.
Recurrent UTIs — residual urine in the prolapsed segment provides a reservoir for bacterial growth.
Urinary incontinence — stress urinary incontinence (leakage with coughing, sneezing) may coexist. Paradoxically, some women with large cystoceles do not have incontinence — the kinked urethra creates outlet obstruction that prevents leakage (occult stress incontinence). This must be assessed before cystocele repair because fixing the prolapse may 'unmask' the incontinence.
Sexual discomfort — the bulge may cause discomfort during intercourse.
Diagnosis at KIMS
Pelvic examination — POP-Q
The POP-Q (Pelvic Organ Prolapse Quantification) system quantifies the degree of prolapse in standardised measurements. Performed in the KIMS urology outpatient clinic.
Post-void residual ultrasound
Measures the volume of urine remaining in the bladder after voiding. A residual above 150 to 200ml indicates significant incomplete emptying.
Urodynamic study
Recommended before surgical repair to: assess bladder capacity, identify detrusor overactivity (OAB component), diagnose occult stress incontinence (by reducing the prolapse during filling cystometry and checking for leakage on coughing), and evaluate urethral function. Essential to plan concurrent anti-incontinence surgery if needed.
Renal ultrasound
For Grade III and IV cystoceles where kinking of the ureter at the VUJ (from the prolapsed bladder) may cause hydronephrosis.
Treatment at KIMS
Conservative — pelvic floor training and pessary
Pelvic floor muscle training and pessary. Pelvic floor muscle training (supervised physiotherapy) strengthens the levator ani and reduces symptoms in Grade I and II cystoceles. Pessary — a silicone ring or cube inserted into the vagina to support the prolapsed bladder — provides effective mechanical support without surgery. Suitable for women who are not surgical candidates or prefer to avoid surgery. Requires pessary cleaning every 3 to 6 months.
Anterior colporrhaphy (anterior vaginal wall repair)
The standard surgical treatment for cystocele — the weakened anterior vaginal wall tissue is plicated (folded and sutured) to restore support. Performed vaginally through the vaginal opening. Success rate 70 to 90% for Grade II and III cystoceles. Recurrence risk at 5 years: approximately 15 to 20%. Concurrent sling procedure (mid-urethral sling) is performed simultaneously for occult or overt stress urinary incontinence identified on pre-operative urodynamics.
Sacrocolpopexy or sacrohysteropexy
For complex or recurrent prolapse. Laparoscopic or robotic suspension of the vault (or uterus, if the uterus is preserved) to the sacral promontory using a mesh tape. Provides a more durable repair than anterior colporrhaphy alone for advanced or recurrent prolapse. At KIMS, this is performed laparoscopically or robotically depending on the complexity of the combined prolapse repair.

Frequently Asked Questions — Bladder Prolapse
A cystocele is not immediately life-threatening, but it progressively worsens quality of life and — if severe — can cause significant complications. Grade III and IV cystoceles causing urinary retention (from urethral kinking) can cause bilateral hydronephrosis and kidney damage from the sustained obstruction — this is the one truly dangerous consequence of untreated severe cystocele. Incomplete emptying from cystocele causes recurrent UTIs with the risk of ascending pyelonephritis. For most women with Grade I and II cystocele, the condition reduces quality of life but is not dangerous in the short term.
Mild cystoceles (Grade I and II) frequently remain stable or improve with pelvic floor muscle training and oestrogen replacement (in postmenopausal women — topical vaginal oestrogen improves connective tissue quality). They do not resolve completely without surgery, but symptoms may be well-controlled non-operatively for years. A properly fitted vaginal pessary provides effective symptomatic relief for women of any prolapse grade who are not suitable for or do not desire surgery. Grade III and IV cystoceles causing significant symptoms, urinary retention, or recurrent UTIs typically require surgical correction.
This is one of the most important pre-operative questions. In approximately 40 to 60% of women with a large cystocele who do not report incontinence symptoms, stress incontinence is present but 'hidden' — the kinked urethra from the prolapse acts as a natural obstruction preventing leakage. When the prolapse is surgically corrected, this obstruction is relieved, and incontinence may emerge. This is called occult (hidden) stress incontinence. Pre-operative urodynamics at KIMS identifies occult incontinence — and a concurrent mid-urethral sling is placed at the time of cystocele repair to prevent post-operative incontinence in these patients.
High-impact exercise — running, jumping, heavy weightlifting, especially with poor technique (Valsalva manoeuvre while lifting) — chronically raises intra-abdominal pressure and can progressively worsen prolapse. Conversely, targeted pelvic floor exercise (correctly performed, with a physiotherapist) strengthens the levator ani and reduces prolapse severity. The recommendation for women with cystocele: engage with pelvic floor physiotherapy to improve the pelvic floor baseline, and modify exercise to reduce high-impact and high-intra-abdominal-pressure activities.
