Rectocele — what it is,
and what actually helps.

Most information about rectocele jumps straight to surgery. But for the majority of women, the first line of treatment isn't an operation — it's learning how to empty without straining, and retraining the muscles that got you here.

Written by the Doctors of Physical Therapy at Root Physical Therapy — on-site inside Root Strength, Georgetown. Dr. Lorrainne, DPT leads our pelvic health care and treats posterior-compartment prolapse regularly. If any of this sounds like you, book an assessment — no referral needed in Washington.

If you've been told you have a rectocele, you've probably already met the two unhelpful extremes. One says it's nothing — just live with it. The other hands you a surgical consult before anyone has asked how you actually use the bathroom.

Both skip the part that matters most. A rectocele is a mechanical problem and a functional one — and the functional half is where physical therapy does its best work. Here's what's structurally happening, what the current evidence supports, and what a real course of treatment looks like.

One

What a rectocele actually is

Your vagina and rectum sit side by side, separated by a wall of connective tissue and muscle — the rectovaginal septum. When that support weakens or tears, the front wall of the rectum can push forward into the back wall of the vagina, creating a bulge.

That's a rectocele: a posterior compartment prolapse. It's the same family of condition as a cystocele (bladder into the front vaginal wall) or uterine prolapse — just a different wall.

The Anatomy

Figure 01

Left: normal support. The rectovaginal septum holds the rectum back, and the vaginal canal stays clear. Right: a rectocele. The weakened wall lets the rectum balloon forward into the vagina — creating a pocket where stool can collect instead of moving toward the anal canal.

That pocket is the key to understanding the symptoms. Stool entering the rectum gets partially diverted forward into the bulge rather than straight down and out. You push, and some of the pressure goes into the pocket instead of through the exit — which is why the defining complaint is so often "I go, but it doesn't feel finished."

Two

What it actually feels like

Rectocele symptoms are frequently misattributed to "just constipation," which is part of why women wait years before mentioning them. The pattern is usually distinctive:

Common Presentations

Figure 02

i

Incomplete emptying — the sense that something is still there after you've finished

ii

Needing to splint — pressing on the perineum or inside the vagina to help stool pass

iii

Straining that doesn't produce a proportional result

iv

A sensation of blockage low down, or of pressure and bulging in the vagina

v

Multiple trips to finish one bowel movement

vi

Symptoms that worsen through the day or with prolonged standing and lifting

vii

Sometimes pain with intercourse, or a visible or palpable bulge

Splinting deserves a word. Many women do it and assume they're the only one — it's a common, sensible adaptation to a mechanical problem. It's also a strong clue that the issue is structural rather than simply slow transit, and it's worth telling a clinician about.

"I go, but it never feels finished" is not a personality quirk. It's a mechanical description.

Three

Why it happens

Prolapse is multifactorial, but the two most consistently identified contributors are vaginal childbirth and advancing age. Beyond those, anything that repeatedly drives pressure downward through the pelvic floor contributes over time: chronic constipation and straining, chronic cough, heavy repetitive lifting without good pressure management, and connective tissue differences.

There's an important feedback loop here. Straining contributes to prolapse — and a rectocele makes emptying harder, which produces more straining. The condition feeds itself. Breaking that loop is the single highest-value thing conservative treatment does.

How Common Is This?

Which means the overwhelming majority of women with prolapse are managed — successfully — without an operation.

Four

What the evidence supports

The strongest trial evidence for conservative management of prolapse comes from POPPY, a multicentre randomised controlled trial published in The Lancet. Women with newly diagnosed stage I–III prolapse were randomised to either an individualised, one-to-one pelvic floor muscle training programme or a lifestyle advice leaflet with no training.

The training group reported significantly fewer prolapse symptoms at both 6 and 12 months, with the difference exceeding the threshold considered clinically meaningful. That's why individualised pelvic floor muscle training — not generic "do your Kegels" instructions — is now a first-line conservative treatment.

Where the evidence is more limited — stated plainly

Physical therapy reliably improves symptoms. It is far less clear that it reverses the anatomy. The honest framing is that conservative care changes how much the prolapse bothers you and how well the system functions — not that it puts the wall back where it started. Separately, a 2025 Cochrane review found that adding pelvic floor muscle training around the time of prolapse surgery did not significantly change reoperation or failure rates. Conservative care is a genuine first-line treatment in its own right; it is not a reliable add-on to guarantee better surgical outcomes.

For the bowel-emptying half of the problem, the evidence is stronger still. When difficulty emptying involves dyssynergic defecation — where the pelvic floor and anal sphincter fail to relax, or paradoxically contract, during attempted evacuation — randomised trials have shown biofeedback-based retraining outperforms both sham biofeedback and standard care (diet, exercise, laxatives), with benefits sustained at one year and beyond.

That matters enormously for rectocele, because dyssynergia and rectocele frequently coexist. If you're pushing against a pelvic floor that's contracting instead of opening, no amount of fibre will fix it — and surgery on the wall won't fix the coordination problem either.

Five

The protocol — what PT actually does

Here's what a course of care looks like at Root PT. It's not a single exercise; it's five pillars, sequenced according to what the assessment finds.

The Five Pillars

Figure 04

I

Assessment — including relaxation, not just strength

The International Continence Society is explicit that pelvic floor assessment should evaluate strength, endurance, coordination, and relaxation. That last one is routinely skipped elsewhere and it changes everything: a pelvic floor that can't relax needs the opposite of a strengthening programme. We assess how you actually generate and release pressure, not just how hard you can squeeze.

II

Defecation mechanics — the highest-yield change

Position, breathing, and effort strategy. Feet supported so the knees sit above the hips, spine long rather than curled, and a slow outward breath instead of a breath-hold and bear-down. The goal is to generate gentle propulsion from above while the pelvic floor opens below — the opposite of straining. For most people this single change produces the fastest symptom relief in the whole plan.

III

Stool consistency — make the mechanics easier

A rectocele copes far better with soft, formed stool than with hard or loose. Fibre, fluid, and (where appropriate, and in coordination with your physician) stool softeners are used deliberately — not as a lifelong crutch but to lower the pressure required to empty while you retrain the mechanics.

IV

Pelvic floor retraining — individualised, supervised

This is the POPPY intervention: one-to-one, individualised, progressive — with technique verified rather than assumed. Depending on findings it may emphasise strength and endurance, or downtraining and coordination, or evacuation-specific retraining with biofeedback where dyssynergia is present. Generic instructions handed out on a leaflet are not the intervention that was tested.

V

Load and pressure management for real life

How you lift, cough, train, and carry matters more than avoiding all of it. We coach breath and bracing strategies so pressure travels through your system rather than straight down onto the posterior wall — which means you can keep lifting and training, with better mechanics. Having a full gym on-site makes that coaching practical rather than theoretical.

Sequencing is individual. Someone whose main driver is dyssynergia needs a very different order of operations than someone with a well-coordinated but weak floor.

The reframe that helps most

You are not trying to push harder. You are trying to make emptying require less push. Almost everything in the protocol above serves that one aim — softer stool, better position, a floor that opens on cue, and pressure directed through the system rather than down into the bulge. Straining is both a symptom and a cause; removing the need to strain is what breaks the cycle.

Six

Pessaries, and when surgery is on the table

A pessary — a removable support device fitted vaginally — is a legitimate, non-surgical option that can provide meaningful symptom relief, particularly for pressure and bulge sensation. Fitting is done by a physician or appropriately trained clinician, and it works well alongside physical therapy rather than instead of it.

Surgical repair is genuinely appropriate for some women: typically those with a symptomatic rectocele from a defined rectovaginal fascial defect whose symptoms haven't responded adequately to conservative care. The important nuance from the surgical literature is that posterior repair should be a deliberate, separate decision — not something automatically bundled with other prolapse repairs.

Why the order matters

Conservative care first is not stalling — it's better surgical decision-making. If your main complaint is incomplete emptying and the underlying driver is dyssynergia, repairing the wall may not resolve the symptom that sent you in. Sorting out mechanics first clarifies how much of your problem is structural and how much is functional — which is exactly the information a surgeon needs.

See a physician promptly if you have

Physical therapy is the right first step for most posterior prolapse symptoms — but these need medical evaluation first:

Rectal bleeding

Unintentional weight loss

A new, persistent change in bowel habit

Tissue protruding outside the vaginal opening

New difficulty emptying your bladder

Fever, severe pain, or signs of infection

Seven

The bottom line

A rectocele is a structural change, but the symptoms that actually bother you — incomplete emptying, straining, splinting, pressure — are substantially driven by function. Function is trainable. That's why conservative care works for most women, why it deserves to come first, and why it makes any later surgical decision a better-informed one.

The other thing worth saying plainly: this is common, it is treatable, and it is nothing to be embarrassed about. The average delay before someone raises these symptoms with a clinician is measured in years — and that delay is the only part of this that's genuinely unnecessary.

The Short Version

• A rectocele is the rectum bulging into the back wall of the vagina — a posterior compartment prolapse.
• The hallmark symptom is incomplete emptying, often with splinting and straining that don't produce results.
• Straining is both cause and consequence. Breaking that loop is the core of treatment.
• Individualised PFMT improves prolapse symptoms — proven in a multicentre RCT (POPPY, Lancet).
• Where dyssynergia is present, biofeedback retraining beats standard care — and it often coexists with rectocele.
• Assessment must include relaxation, not just strength — otherwise the wrong programme gets prescribed.
• Pessary and surgery are real options, but conservative care comes first for most women and sharpens the decision.
