Reproductive · Pelvic Organ Prolapse
The facts most likely to be tested
A cystocele results from the weakening of the pubocervical fascia, leading to the herniation of the bladder into the anterior vaginal wall.
The most significant risk factor for the development of a cystocele is vaginal childbirth due to pelvic floor trauma.
Patients typically present with a sensation of pelvic pressure, a vaginal bulge, and urinary urgency or incomplete bladder emptying.
Physical examination reveals a soft, reducible mass on the anterior vaginal wall that becomes more prominent with the Valsalva maneuver.
The diagnosis of a cystocele is primarily clinical, based on the physical exam findings of anterior vaginal wall prolapse.
First-line management for symptomatic patients who desire non-surgical intervention is the use of a vaginal pessary.
Definitive surgical management for a symptomatic cystocele involves anterior colporrhaphy to repair the damaged pelvic support structures.
Vignette unlocked
A 68-year-old G3P3 woman presents to the clinic complaining of a persistent sensation of pelvic pressure and a feeling that 'something is falling out' of her vagina. She reports occasional urinary urgency and notes that she often has to manually push on her vaginal wall to complete urination. On physical examination, a soft, reducible mass is noted on the anterior vaginal wall that protrudes further during the Valsalva maneuver. The patient has a history of three uncomplicated vaginal deliveries.
What is the most appropriate initial non-surgical management for this patient?
Vaginal pessary
The patient's presentation of an anterior vaginal wall bulge that worsens with Valsalva is classic for a cystocele; a vaginal pessary is the first-line conservative treatment for symptomatic pelvic organ prolapse.

High yield triage
Etiology / Epidemiology
Common in multiparous women due to pelvic floor muscle weakness and loss of connective tissue support.
Clinical Manifestations
Patient reports a feeling of fullness or vaginal bulge that worsens with Valsalva maneuver.
Diagnosis
Pelvic organ prolapse quantification (POP-Q) exam is the gold standard for staging.
Treatment
Kegel exercises for mild cases; pessary for symptomatic relief; surgery for severe cases.
Prognosis
High recurrence rate; post-operative urinary retention is a common complication.

Epidemiology & Etiology
Prevalence increases with age, multiparity, and chronic conditions causing increased intra-abdominal pressure. Obesity and chronic constipation are significant modifiable risk factors. Connective tissue disorders and menopause (estrogen deficiency) further weaken pelvic support structures.
Pertinent Anatomy
The bladder is supported by the pubocervical fascia. A cystocele occurs when this fascia weakens, allowing the bladder to herniate into the anterior vaginal wall.
Pathophysiology
Loss of structural integrity in the levator ani complex and endopelvic fascia leads to descent of the bladder. This creates a cystourethrocele if the urethra is also involved. Chronic strain leads to progressive stretching of the cardinal and uterosacral ligaments.
Clinical Manifestations
Patients present with a sensation of a falling-out mass or vaginal pressure. Symptoms are exacerbated by prolonged standing or straining. Red flags include urinary retention, recurrent UTIs, or hydronephrosis from ureteral kinking.
Diagnosis
Diagnosis is clinical via pelvic exam with the patient in the lithotomy position. The POP-Q system is the gold standard for objective staging. Use a Sims speculum to isolate the anterior wall to confirm the bladder is the herniating organ.
Treatment
First-line for mild/asymptomatic cases is pelvic floor muscle training (Kegels). Symptomatic patients should be fitted with a vaginal pessary. Contraindications for surgery include patients who are not surgical candidates or desire future pregnancy. Surgical repair involves anterior colporrhaphy.
Prognosis
Most patients achieve significant symptom relief with pessary use. Urinary retention and de novo stress incontinence are the most common post-surgical complications. Long-term follow-up is required to monitor for recurrence.
Differential Diagnosis
Rectocele: posterior vaginal wall bulge
Uterine prolapse: cervix descends into the vaginal canal
Enterocele: small bowel herniation into the vaginal vault
Urethral diverticulum: tender suburethral mass with purulent discharge
Vaginal cyst: usually lateral and non-reducible
