Feminizing gender affirmation surgery is a complex genital surgery that most commonly involves removal of natal male genitalia (testes, penile urethra, a majority of the glans penis, penile shaft) and construction of the vulva and/or neovagina utilizing scrotal and penile shaft tissue. Other surgical procedures can also involve using a peritoneal flap or a portion of the small bowel or sigmoid colon to create the neovaginal canal. As with any major surgical procedure, complications do occur, and these can range from minor to major; intraoperative to postoperative. For the purposes of this article, the focus shall be on postoperative complications. Most postoperative complications occur within the first 4 months of the surgery and include vaginal stenosis, genitourinary fistula formation, urinary stream abnormalities, and sexual dysfunction.1 Minor complications that can be managed in the office include granulation tissue treatment, vaginitis, and hair growth in the neovagina. It is important to note that, if any complication occurs, it is essential to refer to the patient’s original surgeon or to a surgeon with expertise in vaginoplasty techniques and postoperative management.2

For patients who undergo vaginoplasty, or a creation of a neovaginal canal, postoperative dilation is necessary to maintain patency. The frequency and duration of dilation are often determined by each individual surgeon or surgical practice as there is no universal, evidence-based standard to guide recommendations on dilation. Failure to maintain a dilation schedule can result in neovaginal stenosis and inability to engage in penetrative vaginal intercourse (if patients desire). Dilation can be difficult.
Challenges with dilation can occur for a variety of reasons: pain, history of trauma, pelvic floor dysfunction, lack of privacy or a supportive environment, or change in personal goals.3 If the underlying cause is related to pelvic floor dysfunction, postoperative pelvic floor therapy has demonstrated improvement in dilation.4 Additionally, routine douching is required for vaginal hygiene. Unlike natal vaginas, neovaginas do not usually contain mucosa, with the exception of a colonic interposition vaginoplasty, and routine douching with soapy water can help prevent a buildup of lubricant and debris.
If a patient reports abnormal discharge, an exam of the vulva and neovagina is warranted. Many patients are able to tolerate a speculum examination. If a patient has undergone a penile inversion vaginoplasty, the microbiome of the neovagina is quite different than that of a natal vagina and most common causes of abnormal discharge often include retained lubricant, keratin debris, sebum, or semen.5 During a speculum exam, the provider may notice granulation tissue, which is often another cause of persistent vaginal discharge, vaginal bleeding, or pain during dilation. Depending on the patient’s symptoms and quantity of granulation tissue present, it can often resolve spontaneously. Persistent granulation tissue can be treated with silver nitrate. An alternative to silver nitrate is using medical grade honey or a course of a mild-strength topical steroid cream or ointment.5 In some cases, abnormal discharge may be the result of a fistula. If a fistula is noted the patient should be immediately referred back to the original surgeon or to a urogynecologist and/or colorectal surgeon for evaluation and management.
While this surgery often falls outside of the scope of practice of the general obstetrician-gynecologist, most patients will seek the care of a general obstetrician-gynecologist in the postoperative period. It is therefore imperative that obstetrician-gynecologists have a basic understanding of the surgical procedure and the aftercare involved.
