Best Pessary for Rectocele (Posterior Vaginal Wall Prolapse): 2026 Complete Guide

The best pessary for rectocele depends on how far the posterior vaginal wall has descended. For mild-to-moderate rectocele, a ring pessary with support is the most-prescribed first device. For severe rectocele, providers typically reach for a Gellhorn or donut pessary. This guide walks through the options, when each one is appropriate, and how to start without a multi-month clinic queue.

What is rectocele?

A rectocele is a prolapse of the posterior (back) vaginal wall. The rectum bulges forward into the vagina because the connective tissue between them — the rectovaginal septum — has weakened. It is one of the four pelvic compartments that can prolapse, alongside cystocele (front wall), uterine prolapse (top), and vaginal vault prolapse (post-hysterectomy).

Rectocele is graded by how far the bulge descends relative to the hymen, using the POP-Q (Pelvic Organ Prolapse Quantification) system:

  • Stage 1: Descent stays more than 1 cm above the hymen
  • Stage 2: Descent reaches within 1 cm of the hymen
  • Stage 3: Descent extends more than 1 cm past the hymen but not full eversion
  • Stage 4: Complete eversion of the posterior wall

Common rectocele symptoms

Symptoms vary by stage. Many Stage 1 rectoceles are silent. Symptoms that prompt evaluation include:

  • A noticeable bulge in the back wall of the vagina
  • Pelvic pressure or heaviness, worse at the end of the day
  • Incomplete bowel emptying — the sense that stool is "stuck"
  • Need to splint (press on the vaginal back wall) to finish a bowel movement
  • Constipation that does not respond to fiber or fluids
  • Lower-back ache that worsens with prolonged standing
  • Discomfort during intercourse

If any of these sound familiar, a pelvic exam confirms the diagnosis. From there, pessary therapy is almost always the first-line non-surgical option.

Why pessaries work for rectocele

A pessary is a flexible silicone device that sits inside the vagina and mechanically supports prolapsed tissue. For rectocele specifically, the pessary holds the posterior wall back, preventing it from bulging into the vaginal canal. That mechanical support relieves pressure, often improves bowel emptying, and lets the rectovaginal septum rest.

Pessaries do not cure rectocele — they manage it. But they can be worn indefinitely with minimal maintenance, and roughly two-thirds of patients with prolapse who try a pessary continue using it long-term.

Ring vs Gellhorn vs Donut: which pessary shape for rectocele?

Three pessary shapes are routinely considered for rectocele. The right choice depends on prolapse stage and whether other compartments are involved.

Pessary type Best for Self-removable Sexually active compatible
Ring with support Mild-to-moderate rectocele (Stage 1-2), often with cystocele Yes With membrane: usually remove first. Without membrane: yes
Gellhorn Severe rectocele (Stage 3-4), uterine prolapse Difficult — usually clinic-managed No — must be removed
Donut Severe rectocele when Gellhorn does not fit Difficult No — must be removed
Ring without support Mild isolated rectocele Yes Yes

Ring with support: the practical first choice

For Stage 1-2 rectocele — the majority of newly diagnosed cases — a Ring Pessary With Support is usually the starting device. It is self-insertable, self-removable, and inexpensive. Patients can manage it at home without weekly clinic visits.

When rectocele coexists with a cystocele (which is common because both compartments share the same risk factors), the ring with support handles both at once — the membrane provides additional anterior support for the bladder.

When Gellhorn is preferred

Severe rectocele (Stage 3-4) often exceeds what a ring can hold back. The Gellhorn shape has a wide concave base and a stem, which lets it sit deeper and resist downward pressure. The trade-off: Gellhorns are harder to remove yourself and are not compatible with intercourse, so most patients have them managed by their provider.

SciMed currently focuses on ring pessaries. If your provider determines you need a Gellhorn, they will source one through their clinic supplier. We are happy to help you compare prices — message us on WhatsApp.

SciMed product recommendation for rectocele

For mild-to-moderate rectocele patients ready to start pessary therapy:

  • Primary choice: Ring Pessary With Support — $49.99. The membrane stabilizes the ring against the anterior wall, which also helps hold the posterior wall back.
  • Alternate for isolated mild rectocele: Ring Without Support — $44.99. Easier folding, easier self-removal.
  • If you have not been fitted: 3-Size Home Fitting Pack — sizes 3, 4, 5. Keep the size that fits.

All SciMed pessaries are FDA Class II medical-grade silicone, HSA/FSA eligible under HCPCS A4561, and ship from California in one business day.

Sizing notes for rectocele patients

Ring sizing for rectocele follows the same rules as for other prolapse compartments. Most rectocele patients land on size 4 (2.75") or size 5 (3.00"). Two rectocele-specific considerations:

  • A ring that fits snug but does not migrate during a bowel movement is correctly sized. Bowel pressure is the toughest test for a rectocele patient — if the ring stays in during a bowel movement, it will stay in everywhere else.
  • If the ring expels during defecation, size up by one. The posterior wall pressure pushes the ring forward and out if it is too small.

The SciMed sizing guide walks through the full at-home protocol.

What to expect in the first 30 days

  1. Day 1-2: Insert in the morning, remove that night. Check for tissue irritation.
  2. Day 3-7: Wear continuously, removing once daily for cleaning. Track bowel symptoms.
  3. Day 8-14: Most patients report easier bowel emptying and reduced bulge feeling by the end of week 2.
  4. Day 15-30: Settle into your long-term routine — weekly cleaning, monthly self-check.
  5. Follow-up: Schedule a provider check at 4-6 weeks to confirm tissue health.

Lifestyle measures that improve outcomes

Pessary therapy works better when combined with conservative measures:

  • Pelvic floor muscle training (Kegels): 3 sets of 10 daily strengthens the muscles around the pessary
  • Fiber and fluids: 25-30 g of fiber daily reduces straining, the primary driver of rectocele progression
  • Stool softeners if needed: avoid straining at all costs
  • Lift safely: exhale during the lift, keep heavy weights close to your body
  • Weight management: excess abdominal weight increases pelvic floor load

When is surgery the better option?

Pessary therapy is first-line for almost everyone, but surgery (posterior colporrhaphy or transvaginal repair) is reasonable when:

  • Multiple pessary types have failed to stay in or relieve symptoms
  • Stage 3-4 rectocele is causing severe defecatory dysfunction
  • The patient has completed childbearing and wants a definitive repair
  • Pessary care creates persistent infection or tissue erosion

Talk to a urogynecologist before choosing surgery. Repair recurrence rates remain around 25-40% within 5 years, so surgery is not a permanent fix either. Many patients use a pessary even after repair.

SciMed cannot make individualized medical recommendations. This information is educational. Your OB-GYN or urogynecologist is the right person to decide between pessary and surgery.

Frequently asked questions

Can a ring pessary really fix a rectocele?

It does not fix the anatomy, but it manages the symptoms. A correctly fitted ring with support relieves the bulge and pressure, and often restores normal bowel emptying. Many patients wear one for years.

Will a pessary stop me from needing surgery?

For many patients with mild-to-moderate rectocele, yes — indefinitely. For severe rectocele, a pessary may delay surgery but not eliminate it. ACOG and AUGS recommend trying conservative therapy first in nearly all cases.

Can I still have a bowel movement with the pessary in?

Yes. A correctly sized ring leaves enough room for normal defecation. If you struggle, the ring is likely too large.

How is rectocele different from a cystocele?

A cystocele is a front-wall (bladder) prolapse; a rectocele is a back-wall (rectum) prolapse. Both are common, and many patients have both at once. The ring with support handles either compartment.

Are rectocele pessaries covered by insurance?

Pessaries fall under HCPCS code A4561 and are HSA/FSA eligible. Most private US insurance covers them with a provider note. SciMed provides itemized receipts.

How long until I notice improvement?

Most patients notice less pressure and easier bowel emptying within 48-72 hours of getting a correctly fitted pessary. Full adaptation takes about 2 weeks.
