Dr. Worawat Kaewwichian

Dr. Worawat Kaewwichian (Thai: นพ. วรวรรธน์ แก้ววิเชียร) is a Thai plastic surgeon who practises at Bumrungrad International Hospital in Bangkok. The hospital publishes his profile as “Worawat Kaewwichian, M.D.” under its specialty label Plastic Cosmetic & Reconstructive Surgery, and he holds his outpatient sessions in the Pride Clinic, the hospital's LGBTQ+ service, which sits on Building A's sixteenth floor.

His documented work is feminizing genital surgery. Bumrungrad's Pride Clinic page on gender-affirming surgery for transgender women names him as one of four “Transgender Plastic Surgeons”, together with Asst. Prof. Dr. Poonpissamai Suwajo, Dr. Krerkwit Visitsakulchai and Dr. Phonlawat Trakunngoenthai. The same page describes vaginoplasty, which the hospital calls neovagina creation, and orchiectomy, the removal of the testes, as operations carried out by its plastic surgeons. Dr. Worawat is also the named author of a 2023 series of Bumrungrad patient-education videos on gender-affirming surgery, one of which explains how a new vagina is created and cared for. On that combined evidence, vaginoplasty and orchiectomy are the two procedures we list under his name.

Dr. Worawat Kaewwichian at a glance

• Specialty: plastic surgery; Bumrungrad label “Plastic Cosmetic & Reconstructive Surgery” (Thai: ศัลยศาสตร์ตกแต่ง)
• Clinic: the Pride Clinic, counter A on Building A's sixteenth floor, Bumrungrad International Hospital (street number 33, Sukhumvit Soi 3 / Nana Nua, Bangkok)
• Published outpatient hours: Wednesday and Friday, 17:00–19:00, as shown on his hospital profile when we checked it on 27 September 2026
• Qualifications: Chulalongkorn University medical degree (2009), then Thai Board diplomas in surgery (2014) and plastic surgery (2016)
• Societies: entries on the member lists of two Thai professional bodies, ThPRS for plastic surgery and RCST for surgery
• Languages: Thai and English
• Procedures documented for him: vaginoplasty and orchiectomy

His surname appears in two romanised spellings. Bumrungrad, the Pride Clinic pages and ThPRS use Kaewwichian, while the RCST member search writes it as Kaewwichain. Both entries carry the same Thai name, วรวรรธน์ แก้ววิเชียร.

You can request a consultation with Dr. Worawat Kaewwichian through our patient team, who check his availability with Bumrungrad and confirm a time with you. Nothing is booked until the hospital confirms it.

Bumrungrad's English and Thai profiles list the same three qualifications for Dr. Worawat. The Thai profile dates them in the Buddhist era (2552, 2557 and 2559), which convert to 2009, 2014 and 2016:

• Medical degree, 2009: Chulalongkorn University (Faculty of Medicine), Doctor of Medicine
• Surgery, 2014: Diploma of the Thai Board of Surgery
• Plastic surgery, 2016: his board diploma in plastic surgery, the specialty under which Bumrungrad lists him

In Thailand, the Thai Board diploma (วุฒิบัตร) marks specialist status: it follows an approved residency programme and success in that specialty's board examinations. His dates show the general surgery diploma came first, with the plastic surgery diploma following two years later.

What his profiles do not say. Neither Bumrungrad profile names the hospital or university where he completed his residency training, and none of the pages we read mention a fellowship, including any dedicated fellowship in gender-affirming surgery, or an academic rank. That does not mean such training did not happen; it means it is not published. If formal training in genital gender-affirming surgery matters to your decision, ask him about it directly at your consultation.

Professional societies

• ThPRS: his entry on thprs.org, the website of Thailand's plastic and reconstructive surgeons' society, dates from January 2020 and gives Phra Narai Maharat Hospital in Lopburi as his address; he also appears in the surgeon directory the society runs at plasticsurgery.or.th.
• RCST: searching by his surname, we found that the Royal College of Surgeons of Thailand lists him in its member database, with surgery recorded as his branch of practice.
• ThSAPS: web-archive copies from 2019 and 2020 of ThSAPS's (Society of Aesthetic Plastic Surgeons of Thailand) old online member list include his Thai name. With no current public list from the society, and no mention of ThSAPS on his Bumrungrad profile, we record this as a past listing, not a confirmed current membership.

Medical licence. No licence number appears on this page. The licence can be looked up on the Medical Council of Thailand's public register at checkmd.tmc.or.th, and our patient team can help you confirm it before you travel. Anyone may run the same name search; entering his Thai name, วรวรรธน์ แก้ววิเชียร, sidesteps the differences between English spellings. How we verify surgeons, and what we do when a source will not open, is set out in our provider research methodology.

Bumrungrad International Hospital, Bangkok (current). Dr. Worawat is listed as a plastic surgeon in Bumrungrad's Pride Clinic, which the hospital describes as providing care for LGBTQ+ people that ranges from gender-affirming hormone treatment to surgery and post-surgical care. The clinic's page for transgender women lists him among its “Transgender Plastic Surgeons”, and its page for transgender men lists him among its “Transgender Medicine Plastic Surgeons”. His hospital profile shows outpatient sessions on Wednesday and Friday evenings from 17:00 to 19:00. His start date at Bumrungrad is not published.

Phra Narai Maharat Hospital, Lopburi. Phra Narai Maharat Hospital (โรงพยาบาลพระนารายณ์มหาราช) in Lopburi, north of Bangkok, listed him among its surgeons (ศัลยแพทย์) on its doctor page in a web-archive copy dated 23 March 2025, and his 2020 ThPRS member entry gives the same hospital as his address. Ask our patient team about his present position there. We do not arrange appointments at Phra Narai Maharat Hospital; consultations requested through us are with his Bumrungrad clinic.

Patient education at Bumrungrad. In mid-2023 Bumrungrad's Thai-language health blog published a “Gender Affirming Surgery VDO series”. Four episodes we opened carry his byline as a plastic surgery specialist (แพทย์ผู้ชำนาญการศัลยศาสตร์ตกแต่ง):

• Ep. 1, on what to know before gender-affirming surgery (29 May 2023)
• Ep. 5, on precautions after bottom surgery (7 June 2023)
• Ep. 6, on caring for the new vagina of transgender women (8 June 2023)
• Ep. 7, on wound care after gender-affirming surgery (6 June 2023)

The Ep. 6 article names orchidectomy as one of the main steps of male-to-female genital surgery and mentions, in general terms, two approaches to building the canal: penile skin inversion with a scrotal skin flap, and a technique using the sigmoid colon. These are hospital patient-information pieces rather than research papers, but they show the ground he covers with patients: preparation, the operation itself, and aftercare. If you read Thai, looking through them before a consultation can help you arrive with sharper questions.

What is not documented. We found no published figures for how many vaginoplasty or orchiectomy operations Dr. Worawat has performed, no complication or revision rates, and no peer-reviewed publication that we could confidently attribute to him. These are fair questions to put to him in person, and a surgeon who performs these operations regularly can usually describe their own results.

Two procedures are documented for Dr. Worawat on official Bumrungrad pages. Each part below starts with what those pages say, then adds general guidance from our procedure guides so you know what the operation usually involves. The general parts describe what patients commonly experience; they are not a description of his personal technique or protocol, which only he can confirm, and your own suitability for either operation needs a personal assessment.

Vaginoplasty (neovagina creation)

*What Bumrungrad documents.* The Pride Clinic's page for transgender women lists “Vaginoplasty (Neovagina Creation)” as a service of its plastic surgeons and names its techniques as penile skin graft, colon graft and penile peritoneal vagina, three in all. Dr. Worawat is one of the four plastic surgeons named on that page, and his Ep. 6 article covers creating and caring for a neovagina. The hospital does not say which of the three techniques each surgeon performs.

*What the operation generally involves.* Speaking generally, surgeons shape three things in this operation (the canal, the clitoris and the labia), and in most cases they take out the testes during the same session. Our vaginoplasty guide outlines three main ways of lining the canal: penile inversion, the most established approach, in which inverted penile skin forms the lining, frequently supplemented by scrotal skin grafts; peritoneal vaginoplasty, which borrows peritoneum, the thin membrane lining the abdomen, for a section of the canal, often with robotic assistance; and colon (sigmoid) vaginoplasty, which uses a length of bowel and tends to be reserved for situations such as revision surgery or a shortage of skin. Bumrungrad's technique names do not map one-to-one onto these terms, so ask Dr. Worawat to explain exactly how the canal would be lined in your case and why he would choose that method for your anatomy.

*Typical timings.* Our guide gives general planning figures: general anaesthesia, an operating time that commonly runs three to six hours, and roughly five to seven nights on the ward with a urinary catheter and a vaginal pack or stent, during which supervised dilation begins. Most patients set aside three to four weeks for the whole trip, and desk-based work is often resumed around six to eight weeks after the operation. Bumrungrad has not published a surgeon-specific protocol, so treat these as planning ranges and confirm the figures that apply to you.

*Before surgery.* The Pride Clinic says it evaluates each patient thoroughly ahead of gender-affirming surgery, checking both whether the body is fit for the operation and whether the patient can weigh up what it offers against what could go wrong. Beyond that, Thai surgeons mostly follow international guidance, chiefly the eighth version of WPATH's Standards of Care (SOC-8). Before genital surgery that usually means a written assessment from a suitably qualified health professional and, unless hormones are clinically unsuitable or not wanted, a spell of hormone treatment, which SOC-8 puts at six months or more. Two supporting letters are still requested by some surgeons. Hair growing from the skin that lines the canal can cause problems later, which is why permanent hair removal beforehand is advised, or insisted on, by many surgeons; as it can take several months, bring it up early.

*After surgery and risks.* Dilation starts in hospital and is done several times daily in the early months; it becomes less frequent with time but is usually lifelong. The complications our guide lists include bleeding, infection, a spraying or narrowed urine stream, delayed or poor wound healing, shrinking of the canal or loss of depth, altered sensation and, in rare but serious cases, a rectovaginal fistula: an unwanted channel between the vagina and the bowel. A second, smaller operation is sometimes chosen later, for example to refine the labia. If you would prefer not to dilate, ask whether vulvoplasty (zero-depth vaginoplasty) is an option with him; nothing published says either way.

Orchiectomy (removal of the testes)

*What Bumrungrad documents.* The same Pride Clinic page lists “Orchiectomy (Testes Removal)” as a separate service performed by its plastic surgeons, and Dr. Worawat's Ep. 6 article names orchidectomy as one of the main steps of male-to-female genital surgery.

*What to know.* Orchiectomy removes both testes. It can be done within a vaginoplasty or as a separate operation, and our orchiectomy page gives about five to seven days in Thailand as a typical stay when it is done alone. Before deciding, patients most need to settle three points:

• It is permanent. Removing the testes ends sperm production. If you might want biological children, discuss sperm storage before surgery, not after.
• Hormones afterwards. Ask how your hormone treatment would change after the operation and who will manage it once you are home; the Pride Clinic also provides gender-affirming hormone treatment.
• Later surgery. If vaginoplasty may follow, ask Dr. Worawat whether a standalone orchiectomy would affect the skin available for it, since common vaginoplasty techniques often use scrotal skin, or whether combining the two operations makes more sense for you.

Other Pride Clinic procedures not listed under his name

The Pride Clinic's page for transgender women also lists facial feminizing surgery, chondrolaryngoplasty (thyroid cartilage shaving) and breast augmentation. Its page for transgender men, which names Dr. Worawat among its plastic surgeons, lists mastectomy (top surgery), phalloplasty and metoidioplasty. These pages describe the clinic team's services without saying which surgeon performs which operation, so we have not attributed them to him. If you are interested in one of these procedures at Bumrungrad, our patient team can ask the clinic which surgeon would see you; the hospital's profile on our site and our gender-affirming surgery section have more background.

Dr. Worawat's published outpatient sessions at the Pride Clinic are on Wednesday and Friday evenings. Bumrungrad's plastic surgery centre says tele-consultations with doctors are available, and telemedicine for patients abroad can be set up through the hospital's Medical Coordination Office, so a first conversation before you travel may be possible; our patient team can ask whether he offers one. Either way, a decision to operate follows an in-person examination and the Pride Clinic's own pre-surgery evaluation.

The questions below are built around the two operations documented for him. Writing down his answers makes it easier to compare them with those of any other surgeon you are considering.

About the operation

• Which vaginoplasty technique do you recommend for me, and why? Which of the techniques on the Pride Clinic page (penile skin graft, colon graft, penile peritoneal vagina) do you perform yourself?
• What canal depth and appearance are realistic for my anatomy, and what would limit them?
• Would the testes be removed during the vaginoplasty, and would you consider a zero-depth vulvoplasty if I asked for one?
• Will you perform the whole operation yourself? Who else operates or assists, and who reviews me on the ward each day?

About eligibility and preparation

• What do you need from me before surgery: how long on hormones, how many assessment letters, and from whom?
• How does the Pride Clinic's pre-surgery evaluation work, and can any part of it be done before I fly?
• Do I need hair removal first? Which areas, and how far ahead should I start?
• Are there health conditions, medicines or habits such as smoking that would change your plan or its timing?

About recovery and follow-up

• How many nights in hospital should I expect, and when does dilation start? Which dilators are supplied?
• How many check-ups will I have in Bangkok before you clear me to fly home?
• After I leave Thailand, who do I contact with a concern, and how are problems handled at a distance?
• Will I receive an operation note and discharge summary in English for my own doctors?

About outcomes and cost

• How often do your patients have narrowing, urinary problems or other complications, and how often do they need a second procedure?
• What does the hospital's estimate include (theatre, anaesthesia, hospital nights, tests, dilators, medication, follow-up visits), and how would treatment for a complication be charged?

If you are considering orchiectomy on its own

• Is a standalone orchiectomy right for me now, or would it be better combined with a later vaginoplasty?
• Should I arrange sperm storage first, and can the hospital help with that?
• How will my hormone treatment change afterwards, and who adjusts it?
• What type of anaesthesia is used, and how many days should I stay in Bangkok?

Dr. Worawat's documented clinic is at Bumrungrad International Hospital, a private hospital that opened in 1980 and stands in Bangkok's Wattana district, off Sukhumvit Road on Soi 3 (Nana Nua). The factsheet the hospital publishes gives 580 inpatient beds. Its Joint Commission International (JCI) accreditation, under JCI's Hospital Program, dates from 2002, and HA Thailand's database shows an advanced-level re-accreditation valid to 22 May 2029. Bumrungrad also appears in the Global Healthcare Accreditation directory, which accredits hospitals for medical travel.

For patients coming from abroad, Bumrungrad publishes these services:

• Medical Coordination Office: Bumrungrad's coordinating doctors and nurses for overseas patients, based on the tenth floor of Building A, charge nothing for their help. Ahead of your trip they look over your records, send estimated prices, fix appointments, set up telemedicine and deal with insurers or embassies; once you are discharged, they supply medical reports and fit-to-fly papers and keep follow-up on track.
• Interpreting: Bumrungrad's factsheet puts its interpreter numbers above 130, with Cultural Support Officers on hand when a patient would rather not use English. Dr. Worawat's own profile lists Thai and English.
• Getting there: a Bumrungrad representative in Suvarnabhumi Airport's international arrivals hall (Exit C, Gate 9, open 07:00–23:00), and a complimentary airport van that leaves roughly every hour, subject to passenger numbers, taking arrivals to Bumrungrad itself or to nearby hotels. From BTS Nana and BTS Phrom Phong, hospital shuttle vans run free of charge every day.
• Longer stays: if your visa needs extending, the hospital's Business Center deals with Bangkok's immigration office on behalf of you and any companions, and the same desk can book hotels, flights and local transport.
• Insurance and embassies: assistance in dealing with international insurers and embassies.

The Pride Clinic can also help with gender-affirming legal documentation.

Planning the length of your stay. Our vaginoplasty guide suggests budgeting three to four weeks in Thailand for that operation, about one of them in hospital, which gives time for wound checks and for you to become comfortable with dilation before the flight home. A standalone orchiectomy is usually planned at around five to seven days. Keep your return date flexible, because your flight date depends on when your surgeon is satisfied with healing, not on the calendar. Many patients travel with a companion and stay somewhere close to the hospital where they can rest in private. Ask for English copies of your operation notes before you leave, so your doctors at home know exactly what was done, and confirm what follow-up you can have once you are back.

Clear information up front helps Dr. Worawat and the Pride Clinic judge whether a video consultation, an in-person visit or further tests should come first. You do not need everything before you make a request; our patient team will tell you what the hospital needs and when.

For any request

• Your name, age, country of residence and how you would like us to contact you
• The procedure you are asking about (vaginoplasty, orchiectomy or both) and your preferred travel window
• Current medicines, including every hormone you take with its dose, route and start date, plus any blood thinners or supplements
• Medical conditions, allergies and any previous problems with anaesthesia
• Previous operations, especially any genital surgery, including circumcision or an earlier orchiectomy
• Height and weight, and whether you smoke or vape
• Recent blood test results, if you have them

For vaginoplasty

• Assessment or referral letters from the health professionals who have supported you, with their names and qualifications
• How long you have been on hormone therapy, or why hormones are not part of your plan
• Your hair-removal history: which areas, which method and how many sessions so far
• What you want from surgery, for example whether canal depth matters to you or whether you would consider zero-depth vulvoplasty

For orchiectomy

• Whether you are planning vaginoplasty later, and roughly when
• Whether you have stored sperm or want to before surgery
• Who prescribes your hormones at home, so aftercare can be coordinated

Photos and privacy

Do not send intimate photographs with a first request. If Dr. Worawat needs clinical photos to plan surgery, our team will say so and explain how to send them securely. Keep copies of everything you send, and bring your letters and hormone records to Bangkok, on paper or on your phone, in case the clinic asks to see them.
