Vaginoplasty & Tightening · Patient guide
What Does Vaginoplasty Actually Repair? The Anatomy Explained
Vaginoplasty repairs four structures: the thinned posterior vaginal wall, which is thickened; the pelvic floor muscles that have separated beneath it, which are brought back together; the perineum at the opening, which is rebuilt if short; and, when the uterus has descended, its supporting ligaments, which are tightened to lift it. At Somssi Women's Clinic in Gangnam, Seoul, Dr. Yoon Ho-joo repairs all of these with your own tissue, from the cervix to the opening.

Key facts
The essentials, based on how Somssi Women's Clinic performs this procedure or answers this question. Your plan is confirmed at consultation.
- Repaired: Posterior vaginal wall, pelvic floor (PC) muscles, perineal body, uterine support (hysteropexy), cul-de-sac
- Not operated on: Anterior wall, urethra, bladder, G-spot region
- Wall change: Posterior wall thickened by about 2–3 cm
- Uterine lift: About 2–4 cm when descended
- Normal vaginal length: About 8–9 cm; prolapse becomes a concern below about 5 cm
- Materials: Own tissue, absorbable sutures, no mesh
Vaginoplasty repairs the structure of the vagina, not just its size: it thickens the posterior wall, re-joins the pelvic floor muscles, rebuilds the perineum and, where needed, restores the uterus to its normal position. Understanding these four layers explains why a procedure that only narrows the opening so often disappoints, and why Somssi Women's Clinic works from the cervix outward.
What changes after childbirth and aging
The vagina is a muscular tube about 8 to 9 cm long, lined with folded mucosa and supported below by the pelvic floor muscles, mainly the pubococcygeus (PC) portion of the levator ani. Behind the cervix a peritoneal pocket, the cul-de-sac, separates the vagina from the rectum. The uterus is held up by ligaments attached to the cervix.
Childbirth stretches all of this. The posterior wall thins, sometimes to only 2 to 3 mm near the cervix, and the muscle layer beneath it thins to 3 to 4 mm. The pelvic floor muscles that should meet in the midline separate, leaving a gap. The perineum may be shortened by tears or episiotomy. And as the ligaments stretch, the cervix descends, shortening the vagina; when the length drops toward 5 cm, prolapse symptoms begin. Aging and menopause thin the tissue further.
The four repairs
1. The posterior vaginal wall
Vaginoplasty thickens the back wall. At Somssi the mucosa is peeled to under 1 mm with micro-scissors rather than excised, then folded and closed with a two-layer fold and fusiform suture. The wall becomes about 2 to 3 cm thick with a ridged, washboard-like surface, restoring the friction and resistance that give both partners sensation. Because the mucosa is peeled rather than cut, the nerves and vessels within the wall stay intact.
2. The pelvic floor muscles
Before the wall is closed, the PC muscles on either side are gathered toward the midline and sutured, closing the gap that childbirth created. This is what raises vaginal pressure when you squeeze, and it is the part of the repair that pelvic floor exercises cannot achieve once the muscle has thinned. At the opening a figure-8 pattern reinforces the muscular ring without creating a tight band.
3. The perineum
When the perineal body between the vagina and anus is short or scarred, it is rebuilt: scar is removed, the perineal muscles are re-approximated and the distance from vagina to anus is restored. This step, perineoplasty, closes a gaping entrance so it matches the canal behind it.
4. Uterine support and the cul-de-sac
If the cervix has descended, its supporting tissues are gathered and sutured so the uterus is lifted by roughly 2 to 4 cm and fixed in place, a hysteropexy. The cul-de-sac is closed (culdoplasty) so the upper vagina has a firm back wall to rest on. This restores vaginal length, and a vagina of normal length is less likely to prolapse again. The uterus stays. Read more under Uterine Prolapse Surgery.
What vaginoplasty deliberately leaves alone
The anterior wall is not operated on. The urethra, bladder and the sensitive G-spot region lie behind it, and surgery there risks urinary problems and numbness. At Somssi a retractor holds the anterior wall away for the whole operation.
This is also why vaginoplasty is not the treatment for every pelvic symptom. A large cystocele (bladder bulging into the front wall) or severe stress incontinence may need separate assessment and a different procedure. Mild stress incontinence often improves when the pelvic floor is repaired, but Dr. Yoon will be honest about what a posterior repair can and cannot do for the bladder.
Why opening-only surgery falls short
Many tightening procedures, including most laser treatments and older triangular or diamond-shaped excisions, work only at the entrance. They narrow the door while the room behind it stays wide, so the inside still feels loose and intercourse can hurt at the opening. After menopause an over-tightened entrance can shrink further and crack. Somssi's revision program sees many women in exactly this situation; its own operation begins at the posterior fornix, in front of the cervix, so the whole canal is treated and the entrance is simply sized to match. The technique is described step by step on our posterior colporrhaphy page.
What this means for symptoms
| Symptom | Structure involved | Repair that addresses it |
|---|---|---|
| Looseness, reduced sensation | Thin posterior wall, separated PC muscles | Wall thickening, muscle approximation |
| Air escaping, water entering | Wide canal, gaping entrance | Canal narrowing, perineal repair |
| Heaviness, "bottom falling out" | Descended uterus, short vagina | Hysteropexy, culdoplasty |
| Odor, recurrent vaginitis | Secretions pooling in a wide canal | Narrowing to the size of the cervix |
| Difficulty emptying the bowel | Rectocele in the posterior wall | Posterior wall repair |
| Mild stress incontinence | Weak pelvic floor | Muscle approximation; severe cases need separate assessment |
What vaginoplasty does not repair
It does not change the labia, which are treated by labiaplasty; it does not restore hormone levels, which may need separate treatment after menopause; and it does not by itself change desire, arousal or a relationship. Dr. Yoon's 2018 research on low sexual desire in Korean women is a reminder that sexual function has many causes, and surgery addresses only the structural ones.
Bottom line
Vaginoplasty rebuilds the posterior vaginal wall, the pelvic floor muscles, the perineum and uterine support, using your own tissue, while leaving the bladder side untouched. Somssi Women's Clinic, a surgical gynecology clinic in Gangnam, Seoul, founded in 2000 and led by Dr. Yoon Ho-joo, MD, PhD, measures each of these structures before recommending what to repair. If you want to know which apply to you, arrange a consultation.

Questions patients ask
Frequently asked questions
Short, honest answers. For anything personal, a consultation is the right place to ask.
Does vaginoplasty tighten the muscles or just the skin?
Both, and the muscle part is the one that matters. The pelvic floor muscles are gathered and sutured toward the midline before the wall is closed, which is what restores pressure and contraction. Procedures that only remove skin or mucosa at the opening tighten the door without rebuilding the muscle, and they tend to stretch back or cause pain.
Can vaginoplasty fix a rectocele?
Yes. A rectocele is a weakness in the posterior vaginal wall that lets the rectum bulge forward. Because vaginoplasty at Somssi is a posterior colporrhaphy, the same repair that thickens the wall and re-joins the muscles closes the rectocele. Women with difficulty emptying the bowel usually find that improves.
Does vaginoplasty lift the uterus?
When the uterus has descended, yes. The supporting tissues around the cervix are gathered and sutured so the uterus rises by about 2 to 4 cm, and the cul-de-sac behind it is closed. This restores vaginal length. If the uterus is in a normal position, as in most women who have not given birth, this step is not needed.
Why is the front wall of the vagina not operated on?
Because the urethra, bladder and the G-spot region lie just behind it. Surgery there can cause urinary problems, numbness and loss of sensation. Tightening can be achieved fully from the posterior wall, so Somssi protects the anterior wall with a retractor throughout and never cuts it.
Will vaginoplasty fix urinary incontinence?
Mild stress incontinence from a weak pelvic floor often improves when the muscles are repaired, in the clinic's experience. Severe stress incontinence or an overactive bladder are separate conditions that need their own assessment and may require a different treatment; see our page on urinary incontinence treatment.
