What it is, what stages mean, how 2a and 2b differ, and what the evidence says about physiotherapy and pessary use.
Prolapse occurs when pelvic organs, the bladder, uterus, or rectum, descend because the muscles, fascia, and ligaments that normally hold them in place have been stretched or weakened. The descent is usually described in relation to the vaginal opening (the vaginal opening).
Common types include a bulge of the bladder into the vaginal wall (bladder prolapse into the front vaginal wall), a bulge of the back wall of the vagina (rectum into the rear wall), uterine prolapse, and prolapse that can occur after a hysterectomy.
Symptoms vary with position and activity. Common experiences include a feeling of heaviness or pressure in the pelvis, a sensation that something is falling out, urinary leakage or difficulty emptying, constipation or incomplete bowel emptying, and discomfort during sexual activity or long periods of standing.
Two main systems are used:
POP-Q (Pelvic Organ Prolapse Quantification), the most precise system, using measured points on the vaginal walls in relation to the the vaginal opening. Used in research and specialist settings.
Baden-Walker, grades 0–4, based on the lowest point of descent relative to the vaginal opening during straining.
Stage 2a, prolapse stays above the vaginal opening, even with straining. Usually mild symptoms, rarely visible externally.
Stage 2b, prolapse reaches the level of the vaginal opening. More noticeable symptoms, may be visible or palpable with straining, and often flares with standing, lifting, and end-of-day activity.
pelvic floor exercises, properly prescribed and progressed, is the first-line conservative treatment for prolapse. The goal is not simply to make the pelvic floor squeeze harder, but to improve timing, graded control, endurance, and coordination with breathing and movement. Symptoms are often managed best when training is done in position-specific progressions (lying first, then sitting, then standing and functional load).
At Stage 2b, the prolapse reaches the vaginal opening and symptoms often flare during everyday activities, standing, coughing, lifting, bowel movements. In this context, a pessary can be a meaningful adjunct to physiotherapy for several reasons:
Addressing constipation, managing chronic cough, avoiding heavy lifting or modifying how loads / abdominal pressure are managed, maintaining a healthy weight, and using topical oestrogen (where appropriate after menopause) all reduce ongoing strain on pelvic support structures.
Surgery is typically considered when symptoms significantly impair quality of life and conservative measures, including well-supervised pelvic floor exercises with or without a pessary, have not provided adequate relief. Surgical options include native tissue repair and mesh procedures; decisions should be made with full information and shared decision-making between patient and specialist.
