Penile peritoneal vaginoplasty — usually shortened to PPV — is among the most advanced techniques in gender-affirming genital surgery. The peritoneum is the tissue lining the abdominal cavity, and it is remarkably close in both function and texture to natal vaginal lining: elastic, self-lubricating, and free of odor.
The technique uses a small amount of penile inversion to form the entrance, combined with peritoneal tissue to create the canal itself. It is performed laparoscopically, through small incisions, leaving virtually no visible scarring.
Although relatively new in gender-affirming care, the approach is not experimental in itself: peritoneal pull-through has been used successfully for decades to treat MRKH syndrome, a congenital condition in which girls are born without a vaginal canal.
Our surgical team, led by Dr. Kamol, has extensive experience with this technique and performs it in high volume.
Advantages of Penile Peritoneal Vaginoplasty / PPV
- Suitable as a primary or revision procedure. It works both as a first-time reconstruction and for patients who have previously had penile inversion surgery and lost depth, or who want an upgrade to something closer to a natal vagina in function, with less maintenance.
- Natural self-lubrication from the peritoneal lining.
- Elasticity, closely resembling natal tissue.
- A hairless canal.
- Lower risk of intestinal complications compared with sigmoid colon vaginoplasty.
- Negligible scarring, thanks to the laparoscopic (keyhole) approach — just four tiny marks that resemble small freckles and fade to near-invisibility within about 12 months.
- A long clinical track record. Peritoneal pull-through has been performed in cisgender women for over 40 years and is well understood.
Disadvantages and limitations
We believe in being clear about the trade-offs:
- Some patients experience indigestion or dyspepsia for 1–2 weeks afterwards.
- Temporary changes in bowel habits can occur over the following weeks — altered frequency, mucous stools, constipation, or back pain (LAR-like syndrome).
- It isn’t suitable for patients who are overweight or carry significant abdominal fat, as internal fat can obscure the peritoneum and make surgery considerably more difficult.
- For patients who are circumcised or have limited penile skin, the surgeon may use hairless scrotal skin to reconstruct the entrance. In that case, laser hair removal is needed for at least 6 months beforehand, or electrolysis during surgery.
- Early dilation can be painful for the first few weeks, because the peritoneum is highly sensitive at first.
- Depth can be lost quickly if dilation isn’t maintained — ongoing commitment is essential.
- Intra-abdominal adhesions occur in approximately 1–2% of cases.
- Because this is a newer application for transgender women without long-term studies yet, candidates should accept the possibility of rare complications that aren’t yet fully characterised.
- Hair removal is required over an area of roughly 5×6 cm at the base of the penis (see Picture 1).
- In complex cases, it may be necessary to convert to a sigmoid colon technique.

Why is Kamol Cosmetic Hospital a world leader in Penile Peritoneum Vaginoplasty SRS-PPV?
Kamol Cosmetic Hospital is a leading provider of gender confirmation surgery, known for achieving consistently excellent results. Our modern hospital is equipped with state-of-the-art technology and techniques, including the advanced SRS-PPV method performed by a specialist abdominal surgeon in collaboration with a plastic surgeon. This technique is not widely available as it requires a specialized skill set and may not be as profitable for other surgeons who prefer to use older, less effective methods.
Our surgeons are highly skilled and experienced. In particular, Dr. Kamol’s technique for SRS involves hiding scars in the labia, resulting in a natural, cisgender appearance. With Dr. Kamol, you can choose the desired appearance of your vulva/vagina within reason. Kamol Cosmetic Hospital is committed to providing our patients the best care and results.
Penile inversion vaginoplasty is a technique that can be used to reconstruct a neovagina as a primary or secondary method. It is particularly beneficial for patients who have undergone sex reassignment surgery and have experienced a loss of depth in their vagina or for those who want a more functional and low-maintenance vagina. This technique has several advantages, including a natural self-lubricating mechanism, fewer risks of intestinal dysfunction compared to the sigmoid colon, and minimal scarring. We use a laparoscopic or keyhole surgery approach, which leaves only four small spots on the abdomen that are barely visible.
Accredited by the Joint Commission International (JCI), the gold standard in global healthcare, Kamol Cosmetic Hospital is a trusted destination for gender confirmation surgery.
Frequently Asked Questions (FAQs)
What is Peritoneal Vaginoplasty (PPV)?
Penile Peritoneal Vaginoplasty (PPV) is a type of vaginoplasty that combines penile inversion with peritoneal lining grafts to create a vaginal canal. The peritoneum, a thin, self-lubricating tissue from the abdominal cavity, is used to help form a deeper, functional vagina with potentially better long-term moisture and elasticity.
PPV is often chosen by patients who have limited donor tissue or who want an alternative to full-depth penile inversion or colon vaginoplasty.
How is PPV different from penile inversion vaginoplasty?
Both use penile skin to form the vaginal entrance. With penile inversion, the whole canal is lined with skin. With PPV, the deeper canal is lined with peritoneum, the moist, elastic tissue inside the abdomen, which brings natural lubrication and a hairless canal. PPV is a longer, laparoscopic operation and isn’t suitable for everyone. Our Gender Reassignment Surgery (SRS) page compares all five techniques we offer.
What are the advantages of PPV over other vaginoplasty techniques?
PPV has several advantages that make it a preferred choice for many:
- Self-Lubrication: The peritoneal tissue naturally produces lubrication, reducing or eliminating the need for artificial lubricants.
- Good Depth: PPV often allows for the creation of a neovagina with sufficient depth for comfortable sexual intercourse.
- Aesthetically Pleasing Results: The resulting neovagina often has a natural appearance.
- Reduced Need for Skin Grafting: In many cases, PPV can avoid the need for skin grafts from other parts of the body, reducing scarring elsewhere.
Who is a good candidate for Peritoneal / Peritoneum Vaginoplasty?
The best way to determine candidacy is through a consultation, but here’s a general overview. Ideal candidates typically:
- Desire Vaginoplasty: You should be sure that you want to undergo the procedure.
- Are in good health: General fitness for surgery is crucial. Existing medical conditions need to be well-managed.
- Have realistic expectations: Understanding the procedure’s capabilities and limitations is vital.
- Are psychologically prepared: A sound mental state and understanding of the long-term commitment to aftercare.
- Undergo hormone therapy: Often, some period of hormone therapy will be beneficial prior to the surgery.
What is dilation, and why is it so important?
Dilation is a key part of the post-operative care. It involves using dilators of increasing sizes to keep the neovagina open and prevent it from closing. It’s essential for maintaining depth and width.
Neglecting dilation can lead to narrowing or closure of the neovagina, which would require further surgery to correct.
Dilation is a long-term commitment. In the initial months after surgery, you’ll need to dilate several times a day. Over time, the frequency can be reduced, but you will likely need to continue dilating indefinitely to maintain the vaginal opening. The exact schedule will be determined by your surgeon based on your individual healing process.
Will I still need lubricant, and when can I have intercourse?
The peritoneal lining produces its own moisture, so many patients need less lubricant than after penile inversion. Some still find a water-based lubricant helpful, especially during early dilation. Intercourse is usually possible after around two to three months, once your surgeon confirms the canal has fully healed.
Can PPV be used to revise a previous vaginoplasty?
Yes. PPV is often used to restore depth for patients who have lost depth after penile inversion surgery, or who want a canal with more natural lubrication. The suitability of a revision depends on the condition of your existing tissue. Learn more about our revision vaginoplasty options.
Does Bangkok, Thailand have good doctors for gender-affirming surgery?
Absolutely. Thailand is a globally recognised centre for gender confirmation surgery, and Bangkok attracts some of the most experienced surgeons in the field. PPV requires a rare combination of laparoscopic and reconstructive expertise, and Kamol Hospital’s specialist team has extensive experience with the technique, delivering consistently strong results with a natural, cisgender appearance.
Should I travel to Thailand for my PPV?
Travelling to Thailand can be an excellent choice if you’re looking to combine highly specialised, high-quality care with better value — particularly for a procedure like PPV that few centres offer. Because recovery involves a hospital stay of several days followed by early dilation and follow-up, it’s important to plan an extended stay before flying home. Kamol Hospital can help schedule your accommodation and appointments, so your recovery in Thailand is well supported.
How long should I stay in Bangkok after PPV?
Expect to spend several nights in hospital, followed by further time in Bangkok for wound checks, catheter removal and dilation training before you fly home. Hair removal at the surgical site must be completed beforehand, so start laser hair removal well before your surgery date. Kamol Trip can help you plan your stay.
