Outcome of Vaginoplasty in Male-to-Female Transgenders: A Systematic Review of Surgical Techniques

Rectal Injury During Penile Inversion Vaginoplasty

OBJECTIVE

To evaluate the incidence, management, and outcomes of rectal injury (RI) and subsequent rectovaginal fistula (RVF) during gender-affirming vaginoplasty (GAV) at a high-volume transgender surgery center.

METHODS

We performed a retrospective review of preoperative, intraoperative and post-operative findings of all patients with RI during GAV from January 2016 to September 2022. Descriptive statistics were calculated using Microsoft Excel.

RESULTS

RI occurred in 9 of 1011 primary GAV and colorectal surgery (CRS) consulted in 5 cases, which included sigmoidoscopy with an air leak test in 4 and with temporary bowel diversion in 2. Of the 9, 6 proceeded with full-depth GAV, and 3 were converted to minimal-depth vaginoplasty. Two had bulbospongiosus muscle interposition and none had a concomitant urethral injury. 1/9 patients with RI developed a RVF which occurred in a patient with prior perineal surgery and no intraoperative sigmoidoscopy. Three (50%) with full-depth GAV developed vaginal stenosis postoperatively.

CONCLUSIONS

RI during primary GAS in experienced hands is uncommon with an incidence of 0.89% in our series of 1011. Unusual tissue dissection planes were a risk factor. If injuries were identified intraoperatively, repaired with multilayer closure and evaluated by CRS, patients did well without the development of RVF despite completion of full-depth GAV. It is reasonable to complete the full-depth vagina, but patients should be advised of a significant risk of post-operative vaginal stenosis.

Transgender and Non-Binary Surgery Registry: Building a Patient-Focused Registry for Genital Gender Affirming Surgery

Purpose

High quality data regarding long-term clinical and patient-reported outcomes (PROs) of genital gender-affirming surgery (GGAS) are lacking, and transgender and non-binary (TGNB) community voices have not historically been included in research development. These factors limit the utility of current research for guiding patients, clinicians, payers, and other GGAS stakeholders in decision-making. The Transgender and Non-Binary Surgery (TRANS) Registry has been developed to meet the needs of GGAS stakeholders and address limitations of traditional GGAS research.

Methods

Development of the TRANS Registry occurred over several developmental phases beginning in May 2019 to present. Stakeholder engagement was performed throughout these phases, including: determination of key clinical outcomes and PROs, creation and implementation of data collection tools within the electronic health record (EHR), and development of centralized registry infrastructure.

Results

The TRANS Registry is a prospective observational registry of individuals seeking vaginoplasty and vulvoplasty. The EHR-enabled infrastructure allows patients and clinicians to contribute longitudinal outcomes data to the TRANS Registry. We describe our community engaged approach to designing the TRANS Registry, including lessons learned, challenges, and future directions.

Conclusions

The TRANS Registry is the first multicenter initiative to prospectively track the health of individuals seeking vaginoplasty and vulvoplasty using EHR-enabled methods, engaging TGNB community members and clinicians as partners in the process. This process may be used as a model for registry development in other emerging fields where high-quality longitudinal outcomes data are needed.

Infections Following Gender-Affirming Vaginoplasty: A Single-Center Experience

We describe the epidemiology and incidence of infections following gender-affirming vaginoplasty. Urinary tract and surgical site infections were the most common infections with incidences of 17.5% and 5.5%, respectively. We also identified a significant gap in human immunodeficiency virus screening and prescription of preexposure prophylaxis.

Insights into the assembly of the neovaginal microbiota in Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome patients

Neovaginas are surgically constructed to correct uterovaginal agenesis in women with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome or as part of gender-affirming surgery for transfeminine individuals. Understanding the assembly of the neovaginal microbiota is crucial for guiding its management. To address this, we conducted a longitudinal study on MRKH patients following laparoscopic peritoneal vaginoplasty. Our findings reveal that the early microbial assemblage exhibited stochastic characteristics, accompanied with a notable bloom of Enterococcus faecalis and genital Mycoplasmas. While both the pre-surgery dimple microbiota and the fecal microbiota constituted the primary species pool, the neovaginal microbiota developed into a microbiota that resembled that of a normal vagina at 6-12 months post-surgery, albeit with a bacterial vaginosis (BV)-like structure. By 2-4 years post-surgery, the neovaginal microbiota had further evolved into a structure closely resembling with the homeostatic pre-surgery dimple microbiota. This concords with the development of the squamous epithelium in the neovagina and highlights the pivotal roles of progressive selective forces imposed by the evolving neovaginal environment and the colonization tropism of vaginal species. Notably, we observed that strains of Lactobacillus crispatus colonizing the neovagina primarily originated from the dimple. Since L. crispatus is generally associated with vaginal health, this finding suggests potential avenues for future research to promote its colonization.

Sexually transmitted infections and the vaginal microbiome after vaginoplasty

PURPOSE OF REVIEW

Transgender and gender-diverse individuals (TGD) are at risk for sexually transmitted infections. Gender affirmation surgery is a cornerstone of care for many TGD individuals. For genital gender affirmation, the surgical creation of a vagina may be performed through a number of techniques. Those who have undergone vaginoplasty have unique anatomical and biopsychosocial considerations, which we discuss.

RECENT FINDINGS

While sexually-transmitted infections including HPV, HSV, HIV, gonorrhea, and chlamydia, have been described in TGD individuals after vaginoplasty, the reports are very rare, and the provider should maintain an index of suspicion and maintain a broad differential for symptoms including neovaginal discharge. We discuss the association of the neovaginal microbiota composition with bacterial vaginosis, and how its modulation could potentially reduce bacterial vaginosis and sexually transmitted infection risk.

SUMMARY

We examine the literature regarding sexually-transmitted infections following vaginoplasty, and the neovaginal microbiome and its similarities and differences relative to the natal vaginal microbiome.

Penile Inversion Vaginoplasty: An Evolving Technique

Penile inversion vaginoplasty (PIV) is the most common surgical technique used in "gender-affirming bottom surgery." During this process, penile tissue is used to create a functional neo-vagina, allowing the individual to experience a more aligned physical manifestation of their "gender" identity. In this technical note, we describe the steps and nuances used by the senior author to ensure reliable aesthetic and functional outcomes, contributing to the overall well-being and satisfaction of transgender patients.

Variant genital gender-affirming surgery: a systematic review

OBJECTIVE

To review the available literature on variant genital gender-affirming surgery (GGAS), including the reasons for performing it, the surgeries themselves and their outcomes.

METHODS

A systematic review on the performance of variant GGAS was conducted (International Prospective Register of Systematic Reviews [PROSPERO] identifier: CRD42022306684) researching PubMed, Embase, Web of Science and Cochrane databases from inception up to 31 December 2023. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and risk of bias was assessed for each study using the five-criteria quality assessment checklist.

RESULTS

In total 23 case series were included, of which 17 on masculinising and six on feminising surgeries. Patients mainly choose these surgical procedures out of personal desire to avoid risk of complication or because they do not have dysphoria about certain parts of their genitalia. Complications in masculinising surgeries primarily arose from the extended urethra, which could be mitigated through primary perineal urethrostomy. Both phalloplasty and metoidioplasty carried a higher risk of urethral complications when the vagina was preserved. In feminising surgeries, risk of visceral damage and requirement for lifelong self-dilation could be avoided when vulvoplasty was performed without vaginal canal creation. All studies had a high risk of bias.

CONCLUSION

This review highlights the importance of variant GGAS and acknowledges the preferences of transgender and gender-diverse individuals. Patients should be informed about the risks and benefits of each step in these procedures.

A comparative analysis of peritoneal flap and intestinal vaginoplasty for management of vaginal stenosis

BACKGROUND

In transgender or non-binary patients (TGNB) with failed penile inversion vaginoplasty (PIV), peritoneal flap vaginoplasty (PFV) and intestinal segment vaginoplasty (ISV) facilitate restoration of neovaginal depth and sexual function. This study compared the outcomes of revision PFV and ISV in TGNB patients with failed PIV.

METHODS

TGNB patients who underwent secondary PFV or ISV from December 2018 to April 2023 were reviewed.

RESULTS

Twenty-one (5.8%) patients underwent secondary PFV and 24 (6.6%) underwent secondary ISV, due to vaginal stenosis (n = 45, 100.0%). Mean duration to first successful dilation and average vaginal depth were comparable between the groups. Seven (33.3%) PFV patients experienced short-term complications, including introital dehiscence (n = 2, 9.5%), vaginal stenosis (n = 2, 9.5%), vaginal bleeding (n = 2, 9.5%), and reoperation (n = 2, 9.5%). Nine (42.9%) experienced long-term complications, including urethrovaginal fistula formation (n = 2, 9.5%), hypergranulation (n = 2, 9.5%), vaginal stenosis (n = 7, 33.3%), and reoperation (n = 6, 28.6%). Ten (41.7%) ISV patients experienced short-term complications, including dehiscence (n = 4, 19.0%), ileus (n = 2, 8.3%), introital stenosis (n = 2, 9.5%), and reoperation due to vaginal bleeding (n = 2, 8.3%). Six (25.0%) experienced long-term complications, including introital stenosis (n = 3, 12.5%), mucosal prolapse (n = 2, 8.3%), and reoperation due to mucosal prolapse (n = 4, 16.7%). Secondary PFV had a higher rate of vaginal stenosis (p = 0.003). There were no cases of partial or full-thickness flap necrosis.

CONCLUSION

Revision PFV and ISV represent viable techniques for addressing vaginal stenosis secondary to PIV. Although PFV and ISV had comparable rates of short-term complications, ISV demonstrated a lower incidence of recurrent vaginal stenosis, which may inform operative decision-making.

Endocrine, gender dysphoria, and sexual function benefits of gender-affirming bilateral orchiectomy: patient outcomes and surgical technique

Background

Gender-affirming bilateral orchiectomy (GABO) may be completed as either a standalone procedure (sGABO) or at the same time as gender-affirming vaginoplasty (vGABO). GABO is postulated to decrease gender-affirming hormone therapy (GAHT) dosages and reduce gender dysphoria, but these phenomena are not empirically described in the medical literature.

Aim

The primary aim of this study was to describe changes in GAHT dosages after sGABO and vGABO. A secondary aim was to assess sGABO patients' preoperative decision-making priorities and postoperative satisfaction.

Methods

A retrospective chart review identified 204 patients who completed GABO as either a standalone procedure (64% of patients) or at the same time as vaginoplasty (36%). Patient demographic data, surgical outcomes, and pre- and postoperative GAHT dosage data were recorded. Patients completed an opinion questionnaire to assessed decision-making priorities, as well as postoperative satisfaction and changes in quality-of-life measures.

Outcomes

Primary outcomes included pre- and postoperative dosages of estradiol, progesterone, and spironolactone. Secondary outcomes included sGABO patient priorities, satisfaction with sGABO, changes in quality-of-life measures between sGABO and vGABO patients, and sGABO recommendations to future patients.

Results

The sGABO and vGABO patients experienced a statistically significant dosage reduction in all three GAHT assessed: estradiol, progesterone, and spironolactone (P < .05). All patients discontinued spironolactone postoperatively. Zero complications related to GABO were recorded for patients in either group. The patient questionnaire revealed that sGABO patients prioritize decreasing endogenous testosterone and reducing their GAHT as most important in their decision to undergo sGABO prior to vaginoplasty. A majority of sGABO patients reported improvement in all nine quality-of-life indices. None of the sGABO patients would recommend against sGABO to a friend who is waiting for vaginoplasty.

Clinical Implications

For patients who are interested in vaginoplasty, sGABO may serve as a more immediate, low-risk, intermediary step that comes with the benefits of GABO, including significant GAHT medication reduction and gender dysphoria relief.

Strengths and Limitations

This study offers a comprehensive evaluation of the impact of GABO on patients, combining empirical data with subjective patient feedback. Limitations include the retrospective design and the use of unvalidated survey questions.

Conclusion

Prevaginoplasty GABO is a viable option to more immediately alleviate gender dysphoria and reduce GAHT medications for patients who are interested in gender-affirming vaginoplasty.

Global and Latest Hotspots of Female Genital Plastic Surgery in the Past 20 Years: A Bibliometric and Visualized Review

BACKGROUND

An increasing number of surgical and nonsurgical interventions are available in the field of female genital plastic surgery. The rate of female genital plastic surgery has increased by nearly 220 percent over the past 5 years. Despite several studies on the topic, no relevant bibliometric analysis has been conducted.

METHODS

We searched the Web of Science Core Collection for articles related to female genital plastic surgery. CiteSpace 6.1.R2 (Drexel University, USA) and VOSviewer 1.6.10.0 (Leiden University, the Netherlands) were used, and national distribution, institutions, journals, authors, and key words were analyzed and calculated.

RESULTS

From 2003 to 2022, 1299 papers in the field of female genital plastic surgery were retrieved. There were more articles produced in the United States, and there were also two institutions in the Netherlands that were highly productive. A wide and close relationship has been established between researchers and institutions conducting female genital plastic surgery. Professor Bouman MB published the most articles on female genital plastic surgery in the Journal of Sexual Medicine. Female genital plastic surgery dominated the top 10 references with the highest local citation score. There were four clusters of key words with the most citations, and the most recently trending key words were "vaginal agenesis," "transgender," and "congenital adrenal hyperplasia."

CONCLUSIONS

The purpose of this article is to provide a summary of the current research status focusing on female genital plastic surgery. It is hoped that more efforts will be made to promote the development of female genital plastic surgery in the future.

The Vaginal Microbiome of Transgender and Gender Nonbinary Individuals

Purpose

The goal of this preliminary study is to describe the vaginal microbiome of transgender and gender nonbinary (TGNB) individuals using nonculture-based techniques. TGNB individuals may undergo gender-affirming surgical procedures, which can include the creation of a neovagina. Little is known about microbial species that comprise this environment in states of health or disease.

Methods

In this pilot study, vaginal swabs were self-collected from 15 healthy self-identified TGNB participants (age 26-69 years) and 8 cisgender comparator participants (age 27-50 years) between 2017 and 2018. Next-generation 16S ribosomal RNA sequencing was used to profile individual bacterial communities from all study samples.

Results

The TGNB cohort demonstrated significantly higher intraindividual (alpha) diversity than the cisgender group (p=0.0003). Microbial species commensal to the gut and skin were identified only in specimens from TGNB participants. Although Lactobacillus species were dominant in all cisgender comparator samples, they were found at low relative abundance (≤3%) in TGNB samples.

Conclusion

In this study, specimens collected from neovaginas showed increased alpha diversity and substantially different composition compared with natal vaginas. In contrast to natal vaginas, neovaginas were not dominated by Lactobacillus, but were hosts to many microbial species. Studies that help to improve our understanding of the neovaginal microbiome may enable clinicians to differentiate between healthy and diseased neovaginal states.

Tissue Options for Construction of the Neovaginal Canal in Gender-Affirming Vaginoplasty

Gender-affirming vaginoplasty (GAV) comprises the construction of a vulva and a neovaginal canal. Although technical nuances of vulvar construction vary between surgeons, vulvar construction is always performed using the homologous penile and scrotal tissues to construct the corresponding vulvar structures. Therefore, the main differentiating factor across gender-affirming vaginoplasty techniques is the tissue that is utilized to construct the neovaginal canal. These tissue types vary markedly in their availability, histology, and ease of harvest and have different advantages and disadvantages to their use as neovaginal lining. In this narrative review, the authors provide a comprehensive overview of the tissue types and associated operative approaches used for construction of the neovagina in GAV. Tissue choice is guided by several factors, such as histological similarity to natal vaginal mucosa, tissue availability, lubrication potential, additional donor site morbidity, and the specific goals of each patient. Skin is used to construct the neovagina in most cases with a combination of pedicled penile skin flaps and scrotal and extra-genital skin grafts. However, skin alternatives such as peritoneum and intestine are increasing in use. Peritoneum and intestine are emerging as options for primary vaginoplasty in cases of limited genital skin or revision vaginoplasty procedures. The increasing number of gender-affirming vaginoplasty procedures performed and the changing patient demographics from factors such as pubertal suppression have resulted in rapidly evolving indications for the use of these differing vaginoplasty techniques. This review sheds light on the use of less frequently utilized tissue types described for construction of the neovaginal canal, including mucosal tissues such as urethral and buccal mucosa, the tunica vaginalis, and dermal matrix allografts and xenografts. Although the body of evidence for each vaginoplasty technique is growing, there is a need for large prospective comparison studies of outcomes between these techniques and the tissue types used to line the neovaginal canal to better define indications and limitations.

The Effect of Obesity on Vaginoplasty Outcomes

BACKGROUND

Some surgeons use body mass index criteria within the patient selection processes before vaginoplasty, thereby limiting access to select obese patients. We sought to better characterize the effect of obesity on postoperative outcomes across multiple vaginoplasty techniques.

METHODS

A single-center retrospective review of all transfeminine patients undergoing primary vaginoplasty procedures from December 2018 to July 2022 was conducted. Patients were stratified into cohorts according to the World Health Organization Obesity Class criteria. Data regarding demographics, comorbidities, operative details, postoperative complications, and all-cause revision were collected.

RESULTS

A total of 237 patients met the inclusion criteria. Average follow-up duration was 9.1 ± 4.7 months. Multivariate regression revealed that patients with class I and class II/III obesity were associated with higher odds of developing vaginal stenosis (class I: odds ratio [OR], 7.1 [ P = 0.003]; class II/III: OR, 3.4 [ P = 0.018]) and all-cause revision (class I: OR, 3.7 [ P = 0.021]; class II/III: OR, 4.8 [ P = 0.027]). Undergoing either robotic peritoneal or robotic intestinal vaginoplasty was associated with lower odds of delayed wound healing (peritoneal: OR, 0.2 [ P < 0.001]; intestinal: OR, 0.2 [ P = 0.011]). Lastly, adherence to dilation regimen was negatively associated with development of vaginal stenosis (OR, 0.04; P < 0.001).

CONCLUSIONS

Patients with obesity may be at a higher risk of developing vaginal stenosis after vaginoplasty, which may ultimately necessitate operative revision. Although patients with obesity may remain surgical candidates, proper preoperative counseling and adherence to postoperative vaginal dilation regimens are critical to optimizing outcomes.

Vaginal Stenosis After Gender-affirming Vaginoplasty: A Systematic Review

OBJECTIVE

To review the literature and report the incidence of vaginal stenosis (VS) after vaginoplasty and compare the incidence rates by surgical technique and follow-up duration.

METHODS

We performed a systematic literature review according to PRISMA guidelines. Original research on primary vaginoplasty was included. Exclusion criteria included non-English studies, mixed cohorts without subgroup analysis, revision vaginoplasty, and papers without stenosis rates. The search was ran in Pubmed, Embase, Scopus, and Cochrane on September 9, 2022. Stenosis rates were compared with descriptive statistics using SPSS.

RESULTS

Fifty-nine studies with a cumulative 7338 subjects were included. The overall incidence of VS was 5.83% (range 0%-34.2%). Combining VS with introital stenosis (IS) and contracture results in a cumulative incidence of 9.68%. The rate of VS in the penile inversion vaginoplasty subgroup (PIV) was 5.70%, compared to 0.20% in primary intestinal vaginoplasty. The rate of IS in the PIV group was 3.13% and 4.7% in the intestinal vaginoplasty subgroup.

CONCLUSION

The overall rate of VS was 5.83%, which is lower than previously documented. This may be related to the inclusion of more recent studies and analysis limited to primary vaginoplasty. The similar rate of IS in PIV and intestinal vaginoplasty subgroups may be secondary to multiple suture lines and the need for dilation through this anastomosis. Our research demonstrates a need for a standardized definition of VS.

Pain mechanisms in the transgender individual: a review

Specific Aim

Provide an overview of the literature addressing major areas pertinent to pain in transgender persons and to identify areas of primary relevance for future research.

Methods

A team of scholars that have previously published on different areas of related research met periodically though zoom conferencing between April 2021 and February 2023 to discuss relevant literature with the goal of providing an overview on the incidence, phenotype, and mechanisms of pain in transgender patients. Review sections were written after gathering information from systematic literature searches of published or publicly available electronic literature to be compiled for publication as part of a topical series on gender and pain in the Frontiers in Pain Research.

Results

While transgender individuals represent a significant and increasingly visible component of the population, many researchers and clinicians are not well informed about the diversity in gender identity, physiology, hormonal status, and gender-affirming medical procedures utilized by transgender and other gender diverse patients. Transgender and cisgender people present with many of the same medical concerns, but research and treatment of these medical needs must reflect an appreciation of how differences in sex, gender, gender-affirming medical procedures, and minoritized status impact pain.

Conclusions

While significant advances have occurred in our appreciation of pain, the review indicates the need to support more targeted research on treatment and prevention of pain in transgender individuals. This is particularly relevant both for gender-affirming medical interventions and related medical care. Of particular importance is the need for large long-term follow-up studies to ascertain best practices for such procedures. A multi-disciplinary approach with personalized interventions is of particular importance to move forward.

Gynecologic Care of Transgender and Gender-Diverse People

The visibility and care of transgender and gender-diverse (TGD) people is an important component of gynecology. Transmasculine individuals require routine gynecologic and preventative care. Guidelines can be extrapolated from the cisgender female population, and using affirming language, acknowledging the challenges patients face with pelvic examination, and discussing individual gynecologic needs are important components of care. Transmasculine patients may seek hysterectomy for gender affirmation from gynecologists. Unique nuances exist in the considerations needed when preparing for hysterectomy, and patients should be thoroughly counseled with regard to concurrent vaginectomy or oophorectomy or both. Transfeminine patients often seek gynecologic care after gender-affirming surgery, and, unlike transmasculine patients, the gynecology visit is often very affirming and welcomed by patients. Becoming familiar with the perioperative and delayed postoperative care needs of transfeminine patients undergoing vaginoplasty can help improve the care provided by gynecologists. In general, prospective data on the outcomes of gender-affirming care in large cohorts of TGD patients are limited, but the body of literature is growing. Gynecologists remain central to the care of TGD patients, the academic advancement of the field of transgender health, and the advocacy needed to support this vulnerable patient population.

Gender-affirming care in urology: emergency care of the gender-affirming surgical patient-what the primary urologist needs to know

OBJECTIVE

To present a narrative review of fundamental information needed to manage postoperative complications in patients who have undergone genital gender-affirming surgery (GAS).

METHODS

A narrative review was performed using the following keywords: 'gender-affirming surgery', 'complications', 'emergency', 'postoperative'. Articles were included after being reviewed by two primary authors for relevance. Four clinicians with significant experience providing both primary and ongoing urological care to patients after GAS were involved in article selection and analysis.

RESULTS

The most common feminising genital GAS performed is a vaginoplasty. The main post-surgical complications seen by urologists include wound healing complications, voiding dysfunction, postoperative bleeding, vaginal stenosis, acute vaginal prolapse and graft loss, rectovaginal fistula, and urethrovaginal fistula. The most common masculinising genital GAS options include metoidioplasty and phalloplasty. Complications for these surgeries include urethral strictures, urethral fistulae, and urethral diverticula. Penile implants may also accompany phalloplasties and their complications include infection, erosion, migration, and mechanical failure.

CONCLUSION

Genital GAS is increasing, yet there are still many barriers that individuals face not only in accessing the surgeries, but in receiving follow-up care critical for optimal outcomes. Improved education and training programmes would be helpful to identify and manage postoperative complications. Broader cultural level changes are also important to ensure a safe, gender-inclusive environment for all patients.

The Most-Cited Publications in Gender-Affirming Surgery: A Cross-Sectional Bibliometric Analysis

Background: Gender-affirming surgery is becoming more common among reconstructive surgeons. Bibliometric analyses are statistical evaluations of published scientific correspondence and are a validated method of measuring influence in the scientific community. As no such bibliometric analysis has been done as of yet, the purpose of this study is to identify the characteristics of the 50 most-cited peer-reviewed articles on gender-affirming surgery. Methods: The Scopus abstract and citation database was utilized in April 2020 to search for English-language publications related to gender-affirming surgery. The 50 most-cited publications that met inclusion criteria were reviewed for various metric tabulations. Results: The 50 publications have been cited a total of 4402 times. Thirty-one (62%) were published in 2000 or later. Phalloplasty was the most discussed surgical technique, and 18 of the articles focused on female-to-male (FtM) patients. Case series (46%) and review articles (24%) were most common and there were no Level I or Level II studies. The Netherlands contributed the most, with 13 articles. Among the most frequent keywords in the 50 abstracts were "flap" and "complication". The earliest author keywords used were "transsexual" and "sex reassignment". Conclusions: The keyword usage in these abstracts over time seems to follow the trend of a more socially inclusive lexicon. A focus on studies with a higher level of evidence may optimize surgeon education and more appropriately guide clinical practice. This study reveals that the most influential and commonly referenced studies may not be sufficient to appropriately guide clinical practices.

The use of Integra Dermal Regeneration Template in the surgical management of revision penile inversion vaginoplasty: A case series

Since its initial design and use for the temporary coverage of severe full-thickness burn defects, Integra® (Integra LifeSciences) Dermal Regeneration Template has been increasingly used all over the body, yielding successful results in coverage of wound beds with insufficient vascularity and suboptimal conditions for proper healing. In this study, we report an institutional case series and outcomes of gender-affirming vaginoplasty revision for vaginal lengthening or reopening of the canal via placement of Integra® to assist in optimizing the wound bed for subsequent skin grafting when wound conditions were deemed to be suboptimal. A retrospective chart review was conducted in patients who underwent this technique by a single surgeon (JM) at the authors' institution. Demographics, vaginal depth, and complications were recorded and compared. Our patient population thus far includes 178 primary vaginoplasties, of which 9 of those needing revision were treated with this approach. The age at revision mean was 47 ± 13.5 years, and the body mass index mean was 31 ± 4.1. All patients had comorbidities and five were former smokers. Eight patients had prior revision conducted without Integra®, with a mean of 1.89 ± 1.76 and the time to first revision mean was 15.89 ± 14.2 months. No long-term complications after Integra® reported and most of the patients did not require further revision. The follow-up mean was 8.48 ± 8.66 months. A mean of 6.77 ± 5.35 cm was gained after the Integra® revision (4.92 ± 4.1 cm before versus 12.54 ± 3.07 cm after). The final depth after Integra® + full-thickness skin graft mean was 13.34 ± 4.65 cm. Overall, the depth gain mean was 7.48 ± 5.77 cm; in total, seven patients gained depth after revision with an average of 78% skin graft take. Overall, Integra® presents an alternative option for revision vaginoplasty with complicated wound beds potentially aiding in the healing process before grafting.

Gender-Affirmative Surgery: A Collaborative Approach between the Surgeon and Mental Health Professional

SUMMARY

Gender incongruence describes a condition in which an individual's gender identity does not align with their sex assigned at birth based on anatomic characteristics. Individuals with gender incongruence may request surgical interventions, and gender-affirmation surgery plays an important role for these individuals. The basis of care derives from principles elucidated in the Standards of Care, international guidelines that help inform clinical decision-making. Historically, mental health care professionals (MHCPs) and surgeons have worked collaboratively to select "appropriate" surgical candidates. However, as understanding of gender identity evolves, so does the relationship between the MHCP and the surgeon. The role of the MHCP has shifted from a requirement to verify an individual's identity to that of supporting and participating in a shared decision-making process between the individual and the health care team. This article discusses the evolution of the relationship between the MHCP and the surgeon and provides insight into the history of this relationship.

[Genital gender affirming surgery in trans women: Vulvo-vaginoplasty review]

INTRODUCTION

A trans woman is a woman who was assigned male at birth, and who has a female gender identity. The majority are requesting a gender affirming genital surgery by vulvo-vaginoplasty. The objective is to review this surgery based on its history, then by presenting the different surgical techniques and their success and complication rates.

MATERIAL AND METHODS

A narrative review was performed, based on a bibliography search with keywords from 2000 to 2022 on Pubmed.

RESULTS

Vulvo-vaginoplasty for trans women began in 1931, and the first case series date from 1969. The procedure includes excision of scrotal skin, orchiectomy, clitoroplasty, urethroplasty, labioplasty, recto-vesico-prostatic dissection and creation of a vaginal cavity (performed by penile skin inversion and graft, intestine, or peritoneum). Vulvo-vaginoplasty by penile skin inversion (VPPI) is today the reference surgical technique. It represents the vast majority of surgeries performed with the longest follow-up. The majority of trans women are satisfied with the procedure aesthetically (90%) and functionally (80%), with an active sexuality. Major complications are rare (< 5%), they correspond to fistulas or vaginal stenosis.

CONCLUSION

VPPI is the gold standard technique with satisfactory overall results, but long-term follow-up is requested.

Vaginal stenosis treatment using computed tomography and fluoroscopy guidance

INTRODUCTION

Vaginal stenosis is a common complication following construction of a neovagina with vascularized myocutaneous flaps. This is primarily because of inconsistent or inappropriate vaginal dilator use. Image-guided recanalization, especially for obstructed genitourinary tracts, is an emerging idea in interventional radiology. Although multiple surgical techniques have been reported to treat vaginal agenesis or obstruction, the idea of image-guided recanalization of vaginal stenosis is a relatively new management strategy for vaginal stenosis.

CASE

We present a challenging case of a patient who initially presented with the complaint of increasing pelvic pressure after the creation of a neovagina via vaginoplasty. She had a distal neovagina created after extensive surgical resection for a large infiltrating pelvic rectal adenocarcinoma. A computed tomography scan revealed a fluid-filled neovaginal abscess. Examination under anesthesia revealed complete stenosis of the neovagina with no identifiable tract for dilation.

INTERVENTION

A computed tomography scan and fluoroscopy-guided sharp recanalization of the stenosed neovagina was performed, followed by serial fluoroscopic balloon angioplasty to dilate the stenosed neovagina. Finally, the patient underwent a gynecologic surgery for the excision of remaining granulation tissue to produce a more permanent patent neovagina, followed by regular and proper use of vaginal dilators to ensure patency.

CONCLUSION

This case report demonstrates that image-guided techniques can be used to aid in vaginal recanalization in the postoperative setting.

Improved sexuality and satisfactory lubrication after genital affirmation surgery using penile skin inversion in transgender women: A satisfaction study

INTRODUCTION

Genital affirmation surgery (GAS) requests are consistently increasing in demand. The gold standard is penile skin inversion, using cutaneous grafting for neovagina creation. The aim is to achieve the most realistic results both physically and functionally. Different studies have contradictory results, and the use of lubrication is insufficiently clear, while the use of sigmoidoplasty has been defended for constant lubrication.

AIMS

Our aim was to evaluate transgender women's sexual function and lubrication after vaginoplasty by penile skin inversion.

METHODS

We performed a prospective study on 45 patients who underwent primary penile inversion vaginoplasty. Participants answered two questionnaires during the follow-up consultation: the Female Sexual Function Index (FSFI) and an 18-item custom questionnaire.

RESULTS

The average FSFI score of our patients was 28.9, up to the cut-off defining a sexual disorder. Compared to the Wylomanski control group, no differences were found for the FSFI score and in the subgroups. Considering lubrication, 69% of the patients were satisfied or very satisfied with their lubrication. Furthermore, 53% reported a fluid release at each orgasm.

CONCLUSION

This study reported high satisfaction for both sexuality and lubrication, proning against penile inversion's GAS bad reputation concerning postoperative lubrication. A squirting effect was described for the first time and was present in 53% of our transpatients.

New Solutions for Old Problems: How Reproductive Tissue Engineering Has Been Revolutionizing Reproductive Medicine

Acquired disorders and congenital defects of the male and female reproductive systems can have profound impacts on patients, causing sexual and endocrine dysfunction and infertility, as well as psychosocial consequences that affect their self-esteem, identity, sexuality, and relationships. Reproductive tissue engineering (REPROTEN) is a promising approach to restore fertility and improve the quality of life of patients with reproductive disorders by developing, replacing, or regenerating cells, tissues, and organs from the reproductive and urinary systems. In this review, we explore the latest advancements in REPROTEN techniques and their applications for addressing degenerative conditions in male and female reproductive organs. We discuss current research and clinical outcomes and highlight the potential of 3D constructs utilizing biomaterials such as scaffolds, cells, and biologically active molecules. Our review offers a comprehensive guide for researchers and clinicians, providing insights into how to reestablish reproductive tissue structure and function using innovative surgical approaches and biomaterials. We highlight the benefits of REPROTEN for patients, including preservation of fertility and hormonal production, reconstruction of uterine and cervical structures, and restoration of sexual and urinary functions. Despite significant progress, REPROTEN still faces ethical and technical challenges that need to be addressed. Our review underscores the importance of continued research in this field to advance the development of effective and safe REPROTEN approaches for patients with reproductive disorders.

Management of Neovaginal Secretions After Salvage Gender Affirming Right-Colon Vaginoplasty Using Glycopyrrolate

Purpose

We report a novel case of a transgender woman who experienced excess mucosal secretion leading to symptomatic skin irritation after her colonic vaginoplasty successfully treated with glycopyrrolate.

Methods

This is a case report of a 47-year-old transgender woman with symptomatic excess mucosal secretion and skin irritation from colonic vaginoplasty, and we describe her treatment course and responses. Patient consent was obtained for publication.

Results

The patient's chronic neovaginal discharge improved with glycopyrrolate.

Conclusions

Anticholinergic drugs may be helpful in treating patients who experience chronic neovaginal discharge following colonic vaginoplasty.

Operative Management of Complications Following Intestinal Vaginoplasty: A Case Series and Systematic Review

OBJECTIVE

To describe the authors' experience with surgical management of complications following intestinal vaginoplasty and review the literature on incidence of complications following gender-affirming intestinal vaginoplasty.

METHODS

Retrospective chart review identified patients presenting with complications following prior intestinal vaginoplasty requiring operative management. Charts were analyzed for medical history, preoperative exam and imaging, intraoperative technique, and long-term outcomes. Systematic literature review was performed to identify primary research on complications following gender-affirming intestinal vaginoplasty.

RESULTS

Four patients presented to the senior authors' clinic requiring operative intervention for complications following intestinal vaginoplasty, all of whom underwent surgical revision. Complications included vaginal stenosis (2 patients, 50%), vaginal false passage (1 patient, 25%), and diversion colitis (1 patient, 25%). Postoperatively all patients were able to dilate successfully to a depth of at least 15 cm. Systematic review identified 10 studies meeting inclusion criteria. There were 215 complications reported across 654 vaginoplasties (33% overall complication rate). Average return to operating room rate was 18%. The most common complications were stenosis (11%), mucorrhea (7%), vaginal prolapse (6%), and malodor (5%). Six intestinal vaginoplasty segments developed vascular compromise leading to flap loss. There were 2 reported mortalities.

CONCLUSION

Intestinal vaginoplasty is associated with a range of complications including vaginal stenosis, mucorrhea, and vaginal prolapse. Intra-abdominal complications, including diversion colitis, anastomotic bowel leak, and intra-abdominal abscess can occur many years after surgery, be life-threatening and require prompt diagnosis and management.

Distinct mucosal and systemic immunological characteristics in transgender women potentially relating to HIV acquisition

Transgender women (TGW) are disproportionally affected by HIV infection, with a global estimated prevalence of 19.9%, often attributed to behavioral risk factors, with less known about biological factors. We evaluated potential biological risk factors for HIV acquisition in TGW at the sites of viral entry by assessing immune parameters of the neovaginal surface and gut mucosa. The neovagina in TGW, compared with the vagina in cisgender women (CW), shows distinct cell composition and may pose a more inflammatory environment, evidenced by increased CD4+ T cell activation and higher levels of soluble markers of inflammation (C-reactive protein, soluble CD30). Increased inflammation may be driven by microbiome composition, as shown by a greater abundance of Prevotella and a higher Shannon Diversity Index. In addition, we have observed higher frequency of CD4+CCR5+ target cells and decreased DNA methylation of the CCR5 gene in the gut mucosa of TGW compared with CW and men who have sex with men, which was inversely correlated with testosterone levels. The rectal microbiome composition in TGW appears to favor a proinflammatory milieu as well as mucosal barrier disruption. Thus, it is possible that increased inflammation and higher frequencies of CCR5-expressing target cells at sites of mucosal viral entry may contribute to increased risk of HIV acquisition in TGW, with further validation in larger studies warranted.

Ileal interposition reconstruction for ileo-rectal fistula following sex reassignment surgery: A case report

INTRODUCTION

Ileorectal fistulas following sigmoid colon vaginoplasty are rare. Reports on the management of the surgical complications of sex reassignment operations among transgender patients are few.

PRESENTATION OF CASE

A 40-year-old patient with a male-to-female sex identity disorder underwent sigmoid vaginoplasty for sex reassignment 4 months prior to presentation. The patient was referred for persistent diarrhea and postoperative lower abdominal pain. Proctoscopy, gastrografin enema, and small bowel enterography revealed rectal anastomotic stenosis and an ileorectal fistula. The prior anastomotic site and ileal rectal fistula were resected, and ileal interposition reconstruction was performed to avoid damaging the blood supply to the artificial vagina. Routine follow-up after the closure of the diverting ileostomy showed no new pathologies.

DISCUSSION

This case highlighted the management of surgical complications after sex reassignment surgery.

CONCLUSION

Ileal interposition was a useful reconstruction method after resecting the colonic anastomotic site to preserve the artificial vagina.

The microbiome of the neovagina: a systematic review and comparison of surgical techniques

Introduction : Vaginoplasty is performed to create a neovagina for transgender individuals who seek surgical transition or for cisgender individuals with congenital or acquired absence of a vagina (or "cisvagina"). The current knowledge of the bacterial microenvironment of the neovagina is limited. The objective of this study was to conduct a systematic review of current knowledge regarding the microbiome of the neovagina in transgender women. Methods : A systematic review of three medical databases (PubMed, MEDLINE, Web of Science) was performed in December 2021. Articles were included if they discussed the bacterial flora of the post-surgical neovagina in transgender women. Articles were excluded if their primary focus was pathogenic disease of the neovagina. Articles were summarized qualitatively and organized into a table. Results : Ten articles were identified for the review. Surgical techniques included penile inversion vaginoplasty (PIV) and intestinal/sigmoid vaginoplasty. PIV neovaginas were most similar to cisvaginas with bacterial vaginosis, whereas intestinal vaginoplasty resulted in microbiomes comparable to that of the colorectum. Oral probiotic supplements may be able to encourage the growth of Lactobacillus in the neovagina. Maintenance protocols relating to cleaning are largely surgeon- and institution-dependent, and evidence regarding the use of estrogen and its effect on the neovagina is limited. Conclusions : The microbiome of the neovagina is distinct from that of the cisvagina, and it differs based on surgical technique. Further research is warranted to better characterize the effect of different surgical techniques, patient characteristics, estrogen use, and cleaning habits on the health of the neovaginal microbiome.

(De-)centralized health care delivery, surgical outcome, and psychosocial health of transgender and gender-diverse people undergoing vaginoplasty: results of a retrospective, single-center study

PURPOSE

Previous research on genital gender-affirming surgery lacked to build a framework that took various surrounding factors into account. E.g., transgender health care services are delivered in both centralized (by one interdisciplinary institution) and decentralized settings (by different medical institutions spread over several locations). The present study investigated the effects of different structural and clinical aspects of gender-affirming genital surgery on psychosocial outcomes.

METHODS

We surveyed former transgender and gender-diverse people who completed a vaginoplasty between 2014 and 2018. 45 participants were included in the study. We calculated hierarchical linear regression analyses to assess the relationship between psychosocial outcome measures (gender congruence, mental health, quality of life) and different aspects of gender-affirming genital surgery (e.g., setting of service delivery). To address shortcomings regarding the small sample size, we applied a rigorous statistical approach (e.g., Bonferroni correction) to ensure that we only identify predictors that are actually related to the outcomes.

RESULTS

A non-responder analysis revealed no systematic bias in the recruitment procedure. Treatment satisfaction was a significant predictor for gender congruence. Moreover, we found the setting of service delivery (centralized, decentralized) to predict psychological health and the physical health dimension of quality of life. The effect sizes of our models were moderate to high, and models explained up to 26% of the total variance with a power up to 0.83.

CONCLUSION

The present study is an exploratory attempt into the manifold relationships between treatment-related factors (e.g., aesthetic outcome), the setting of service delivery, and their effects on gender-affirming genital surgery.

Exploring the Relationship between (De-)Centralized Health Care Delivery, Client-Centeredness, and Health Outcomes-Results of a Retrospective, Single-Center Study of Transgender People Undergoing Vaginoplasty

Introduction: Transgender health care interventions (e.g., gender-affirming surgery) support transgender and gender-diverse people to transition to their gender and are delivered in both centralized (by one interdisciplinary institution) and decentralized settings (by different institutions spread over several locations). In this exploratory study, we investigated the relationship between centralized and decentralized delivery of transgender health care, client-centeredness, and psychosocial outcomes. Methods: A retrospective analysis of 45 clients undergoing vaginoplasty at one medical center was conducted. Mann-Whitney U tests assessed differences regarding five dimensions of client-centeredness and psychosocial outcomes between the health care delivery groups. To address shortcomings regarding the small sample size, we applied a rigorous statistical approach (e.g., Bonferroni correction) to ensure that we only identified predictors that were actually related to the outcomes. Results: All aspects of client-centered care were scored average or high. Decentralized delivery of care was more client-centered in terms of involvement in care/shared decision-making and empowerment. However, participants from decentralized health care delivery settings scored lower on psychosocial health (p = 0.038-0.005). Conclusions: The factor of (de-)centralized health care delivery appears to have a significant impact on the provision of transgender health care and should be investigated by future research.

Major complications of sigmoid vaginoplasty: a case series

This case series explores the major complications following sigmoid vaginoplasty in two transgender female patients. Both patients experienced significant post-operative complications, including stenosis and abscess formation, leading to sigmoid conduit ischemia and necrosis. These complications required major surgical interventions and multidisciplinary care, highlighting the complexity of these procedures and their potential morbidity. Our analysis suggests that the initial stenotic insult led to obstruction and vascular insult to the sigmoid conduit, necessitating resection of the affected bowel. The outcomes underscore the need for collaboration across specialties for optimal post-operative monitoring and management. This study advocates for future management guidelines promoting multidisciplinary collaboration to reduce morbidity and resource burdens associated with complications. Despite the complications, sigmoid vaginoplasty remains a viable gender affirmation surgery, providing an effective analogue to vaginal mucosa and offering improved neovaginal depth.

Gender-affirming Vaginoplasty and Vulvoplasty: An Initial Experience

OBJECTIVE

To describe the initial outcomes of a new multidisciplinary gender-affirming surgery (GAS) program comprised of plastic and urologic surgeons.

METHODS

We retrospectively examined consecutive patients who underwent gender-affirming vaginoplasty or vulvoplasty between April 2018 and May 2021. We used logistic regression modeling to analyze associations between preoperative risk factors and postoperative complications.

RESULTS

Between April 2018 and May 2021, 77 genital GAS (gender-affirming surgery) procedures were performed at our institution (56 vaginoplasties, 21 vulvoplasties). All surgeries were performed in combination with urology and plastic surgery primarily using the perineal penile inversion technique. Mean patient age was 39.6 years, and mean BMI was 26.2 (Table 1a). The most common pre-existing conditions were hypertension and depression, with nearly 14% of patients reporting a previous suicide attempt. The complication rate for vaginoplasty was 53.7% within the first 30 days (Table 4). The most common complications were yeast infection (14.8%) and hematoma (9.3%). For vulvoplasty, the 30-day complication rate was 57.1%, with urinary tract infection (14.3%) and granulation tissue (9.5%) being the most common. 88.1% and 91.7% of the complications were Clavien-Dindo grade I or II for vaginoplasties and vulvoplasties, respectively. No association was found between preoperative patient factors and postoperative complications. Revision surgeries were performed for 38.9% of vaginoplasty patients during the study period, most commonly including urethral revision (29.6%), labia majoraplasty (20.4%), and labia minoraplasty (14.8%).

CONCLUSION

Collaboration between urology and plastic surgery is a safe and effective means to establish a GAS program.

Genital gender-affirming surgery for transgender women

Transgender women may opt for genital gender-affirming surgery (gGAS), which comprises bilateral orchiectomy, gender-affirming vulvoplasty, or vaginoplasty. Vaginoplasty is chosen most frequently in this population, penile inversion vaginoplasty being the surgical gold standard. In selected cases, skin graft vaginoplasty, intestinal vaginoplasty, or peritoneal vaginoplasty may be indicated. In this article, we discuss the various types of gGAS for transgender women, (contra)-indications, intraoperative considerations, techniques, surgical outcomes, and postoperative patient-reported outcomes.

Principles and outcomes of gender-affirming vaginoplasty

Vaginoplasty is the most frequently performed gender-affirming genital surgery for gender-diverse people with genital gender incongruence. The procedure is performed to create an aesthetic and functional vulva and vaginal canal that enables receptive intercourse, erogenous clitoral sensation and a downward-directed urine stream. Penile inversion vaginoplasty (PIV) is a single surgical procedure involving anatomical component rearrangement of the penis and scrotum that enables many patients to meet these anatomical goals. Other options include minimal-depth, peritoneal and intestinal vaginoplasty. Patient quality of life has been shown to improve drastically after vaginoplasty, but complication rates have been documented to be as high as 70%. Fortunately, most complications do not alter long-term postoperative clinical outcomes and can be managed without surgical intervention in the acute perioperative phase. However, major complications, such as rectal injury, rectovaginal fistula, and urethral or introital stenosis can substantially affect the patient experience. Innovations in surgical approaches and techniques have demonstrated promising early results for reducing complications and augmenting vaginal depth, but long-term data are scarce.

Complications After Orchiectomy and Vaginoplasty for Gender Affirmation: An Analysis of Concurrent Versus Separate Procedures Using a National Database

IMPORTANCE

Gender-affirming orchiectomy may be performed in isolation, as a bridge to vaginoplasty, or concurrently with vaginoplasty for transgender and nonbinary persons, although there is a paucity of data on immediate postoperative outcomes on the various procedural approaches.

OBJECTIVE

The aim of the study is to compare 30-day surgical outcomes after gender-affirming orchiectomy and vaginoplasty as separate and isolated procedures.

STUDY DESIGN

This was a retrospective cohort study of patients in the American College of Surgeons National Surgical Quality Improvement Program database to compare surgical outcomes of orchiectomy alone and vaginoplasty alone to concurrent orchiectomy with vaginoplasty using bivariate and adjusted multivariable regression statistics.

RESULTS

Concurrent orchiectomy and vaginoplasty were associated with greater 30-day surgical complications compared with orchiectomy alone (15.4% vs 2.9%, P < 0.01) and similar odds of 30-day surgical complications compared with vaginoplasty alone (15.4% vs 11.1%, P = 0.15). On multivariable logistic regression analysis, compared with orchiectomy alone, concurrent orchiectomy and vaginoplasty were associated with higher increased odds of 30-day surgical complications (adjusted odds ratio, 6.48; 95% confidence interval, 2.83-14.86) as well as vaginoplasty alone (adjusted odds ratio 4.30; 95% confidence interval, 1.85-10.00).

CONCLUSIONS

This study highlights the perioperative outcomes for isolated versus concurrent gender-affirming orchiectomy and vaginoplasty, demonstrating lower morbidity for orchiectomy alone and similar morbidity for vaginoplasty alone when compared with concurrent procedures. These data will aid health care providers in preoperative counseling and surgical planning for gender-affirming genital surgery, particularly for patients considering concurrent versus staged orchiectomy and vaginoplasty.

Tissue Engineering Neovagina for Vaginoplasty in Mayer-Rokitansky-Küster-Hauser Syndrome and Gender Dysphoria Patients: A Systematic Review

Background: Vaginoplasty is a surgical solution to multiple disorders, including Mayer-Rokitansky-Küster-Hauser syndrome and male-to-female gender dysphoria. Using nonvaginal tissues for these reconstructions is associated with many complications, and autologous vaginal tissue may not be sufficient. The potential of tissue engineering for vaginoplasty was studied through a systematic bibliography search. Cell types, biomaterials, and signaling factors were analyzed by investigating advantages, disadvantages, complications, and research quantity. Search Methods: A systematic search was performed in Medline, EMBASE, Web of Science, and Scopus until March 8, 2022. Term combinations for tissue engineering, guided tissue regeneration, regenerative medicine, and tissue scaffold were applied, together with vaginoplasty and neovagina. The snowball method was performed on references and a Google Scholar search on the first 200 hits. Original research articles on human and/or animal subjects that met the inclusion (reconstruction of vaginal tissue and tissue engineering method) and no exclusion criteria (not available as full text; written in foreign language; nonoriginal study article; genital surgery other than neovaginal reconstruction; and vaginal reconstruction with autologous or allogenic tissue without tissue engineering or scaffold) were assessed. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist, the Newcastle-Ottawa Scale, and the Gold Standard Publication Checklist were used to evaluate article quality and bias. Outcomes: A total of 31 out of 1569 articles were included. Data extraction was based on cell origin and type, biomaterial nature and composition, host species, number of hosts and controls, neovaginal size, replacement fraction, and signaling factors. An overview of used tissue engineering methods for neovaginal formation was created, showing high variance of cell types, biomaterials, and signaling factors and the same topics were rarely covered multiple times. Autologous vaginal cells and extracellular matrix-based biomaterials showed preferential properties, and stem cells carry potential. However, quality confirmation of orthotopic cell-seeded acellular vaginal matrix by clinical trials is needed as well as exploration of signaling factors for vaginoplasty. Impact statement General article quality was weak to sufficient due to unreported cofounders and incomplete animal study descriptions. Article quality and heterogenicity made identification of optimal cell types, biomaterials, or signaling factors unreliable. However, trends showed that autologous cells prevent complications and compatibility issues such as healthy cell destruction, whereas stem cells prevent cross talk (interference of signaling pathways by signals from other cell types) and rejection (but need confirmation testing beyond animal trials). Natural (orthotopic) extracellular matrix biomaterials have great preferential properties that encourage future research, and signaling factors for vascularization are important for tissue engineering of full-sized neovagina.

Patient reported symptoms and adverse outcomes seen in Canada's first vaginoplasty postoperative care clinic

IMPORTANCE

Vaginoplasty is a relatively common gender-affirming surgery with approximately 200 Ontarians seeking this surgery annually. Although Ontario now offers vaginoplasty in province, the capacity is not meeting demand; the majority of trans and gender-diverse patients continue to seek vaginoplasty out of province. Out-of-province surgery presents a barrier to accessing postsurgical follow-up care leaving most patients to seek support from their primary care providers or providers with little experience in gender-affirming surgery.

OBJECTIVE

To provide an account of the common postoperative care needs and neovaginal concerns of Ontarians who underwent penile inversion vaginoplasty out of province and presented for care at a gender-affirming surgery postoperative care clinic.

DESIGN, SETTINGS, AND PARTICIPANTS

A retrospective chart review of the first 80 patients presenting to a gender-affirming surgery postoperative care clinic who had undergone vaginoplasty at an outside surgical center was performed. Descriptive analyses were performed for all variables.

RESULTS

The sample consisted of 80 individuals with the mean age of 39 years (19-73). Most patients had surgery at another surgical center in Canada (76.3%). Many patients (22.5%) accessed care in the first 3 months after surgery, with the majority (55%) seeking care within the first perioperative year. Most patients (61.3%) were seen for more than one visit and presented with more than two symptoms or concerns. Common patient-reported symptoms during clinical visit included pain (53.8%), dilation concerns (46.3%), and surgical site/vaginal bleeding (42.5%). Sexual function concerns were also common (33.8%) with anorgasmia (11.3%) and dyspareunia (11.3%) being the most frequent complications. The most common adverse outcomes identified by health care providers included hypergranulation (38.8%), urinary dysfunction (18.8%), and wound healing issues (12.5%).

CONCLUSIONS AND RELEVANCE

Findings from chart review offer valuable insights into the postoperative needs and neovaginal concerns of Ontarians who have had vaginoplasty out of province. This study demonstrates the need for routine postoperative care in patients undergoing vaginoplasty. Patients experience numerous symptoms and concerns that often correlate with clinical findings and require multiple follow-up appointments. Health care providers may benefit from further education on the more common nonsurgical issues identified in this study.

Urological and Gynaecological Considerations for the Use of Gonadotropin-releasing Hormone Analogues in Transgender and Nonbinary Adolescents: A Narrative Review

CONTEXT

Gonadotropin-releasing hormone analogues (GnRHAs) delay the progression of puberty in transgender and nonbinary (TGNB) adolescents and reduce the impact of dysphoria due to ongoing physical development. The intervention remains contentious despite growing evidence to support this practice.

OBJECTIVE

To stimulate discussion on this topical issue in the urological and gynaecological community given potential ramifications for future fertility, physical development, and options for gender affirmation surgery (GAS).

EVIDENCE ACQUISITION

We conducted searches of the MEDLINE (from 1946) and Embase (from 1974) databases for the benefits and potential challenges of hormone blockade in TGNB adolescents on February 1, 2022. Evidence with a primary focus on clinical issues of interest to urologists and gynaecologists was objectively synthesised and reported.

EVIDENCE SYNTHESIS

The onset of puberty represents a period of distress for TGNB adolescents as secondary sexual characteristics develop. GnRHAs are prescribed to inhibit sex hormone production, but the decision to treat should be balanced against the known (and unknown) adverse effects. Fertility preservation is more likely to be successful if GnRHA treatment is delayed for as long as possible. Some adolescents may decide to stop GnRHA use to harvest spermatozoa or oocytes before starting gender-affirming hormone treatment. Transfeminine individuals should consider that options for genital GAS may become more limited, as vaginoplasty with penile skin inversion requires an adequate stretched penile length. Transmasculine individuals may no longer require chest reconstruction for breast development.

CONCLUSIONS

Offers of GnRHA treatment to TGNB adolescents should be balanced by careful preparation and counselling. Urologists and gynaecologists can complement the expertise of specialist psychosocial and adolescent endocrinology teams, and should be involved early in and throughout the treatment pathway to maximise future functional and surgical outcomes.

PATIENT SUMMARY

Puberty blockers for transgender and nonbinary adolescents have benefits, but timing is important to preserve fertility and surgical options.

Outcome measures reported following feminizing genital gender affirmation surgery for transgender women and gender diverse individuals: A systematic review

Background

Feminizing genital gender affirmation surgery (fgGAS) may be an essential adjunct in the care of some transgender women and gender diverse individuals with gender incongruence. However, the comparison of different techniques of fgGAS may be confounded by variable outcome reporting and the use of inconsistent outcomes in the literature. This systematic review provides the most in-depth examination of fgGAS studies to date, and summarizes all reported outcomes, definitions, and the times when outcomes were assessed following these surgical interventions. Aims/Methods: This work intends to quantify the levels of outcome variability and definition heterogeneity in this expanding field and provides guidance on outcome reporting for future study authors. Candidate studies for this systematic review were sourced via an electronic, multi-database literature search. All primary, clinical research studies of fgGAS were included with no date limits. Paired collaborators screened each study for inclusion and performed data extraction to document the outcomes, definitions, and times of outcome assessment following fgGAS.

Results

After screening 1225 studies, 93 studies proceeded to data extraction, representing 7681 patients. 2621 separate individual outcomes were reported, 857 (32.7%) were defined, and the time of outcome assessment was given for 1856 outcomes (70.8%) but relied on nonspecific ranges of follow-up dates. "Attainment of orgasm", "Neovaginal stenosis", and "Neovaginal depth/length" were among the most commonly reported outcomes. Profound heterogeneity existed in the definitions used for these and for all outcomes reported in general.

Discussion

The results demonstrate a need for clear outcomes, agreed definitions, and times of outcome assessment following fgGAS in transgender women and gender diverse individuals. The adoption of a consistent set of outcomes and definitions reported by all future studies of fgGAS (a Core Outcome Set) will aid in improving treatment comparisons in this patient group. This review is the first step in that process.

3D printing technique applied in vaginoplasty: A case report

Background

We present the first case report of the treatment of congenital vaginal atresia by 3D-printed patient-specific vaginal scaffold from China.

Case presentation

A 17-year-old female patient was referred to our department for treatment of congenital vaginal atresia and complications arising from previous failed operations. Pelvic examination was conducted to understand the morphological characteristics and severity of stenosis, and based on which we designed our prototypes of vaginal scaffold using software UG NX10.0. We finally obtained our patient-specific mold, which was 50 mm in length, 28 mm in diameter, 2 mm of thickness with a whole weight of 7.6 g, and it was made of polycaprolactone. After removing scar tissues caused by vaginal stenosis, an 8 cm long artificial tunnel was created, and then the polycaprolactone (PCL) vaginal mold was placed and sutured. The patient had no discomfort after surgery and was discharged 3 days after the surgery. Follow-up for 1 year after surgery, through hysteroscopy and colposcopy, it was found that the cervix was smooth, the vaginal wall was covered with stratified squamous epithelium, and the vaginal wall was soft and lubricated, which was close to a normal vagina. The incompletely absorbed mold was taken out one year after the operation. Hysteroscopy and colposcopy were performed one year and two years after the mold was taken out. The vagina was unobstructed and the length was about 12 cm. The appearance of the vaginal wrinkles was normal. The patient's quality of sexual life was good.

Conclusion

Our team tried to treat congenital vaginal atresia by 3D-printed patient-specific vaginal scaffold, which can effectively reduce patient complications and reduce patient pain. Through long-term follow-up, we found that this technique has achieved favorable results and improved the patient's quality of sexual life.

Gender Affirmation Surgery on the Rise: Analysis of Trends and Outcomes

Purpose: Gender-affirming surgery (GAS) has become an important component of the treatment of gender dysphoria. Although the frequency of these procedures is on the rise, a complete safety profile has yet to be established. The goal of our study is to analyze the trends and outcomes of these surgical procedures. Methods: All patients with a primary diagnosis of gender dysphoria undergoing GAS were identified from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database between the years 2009 and 2018. Patient demographics and 30-day postoperative outcomes were recorded. We performed a multivariate logistic regression for postoperative complications, controlling for several confounding variables. Results: We identified 2956 patients, of which 1767 (59.78%) were transgender men and 1189 (40.22%) were transgender women. The number of patients undergoing GAS per year increased from 7 in 2010 to 1069 in 2018, a 152-fold increase. For patients undergoing top surgery, Black race (odds ratio [OR] = 2.255, 95% confidence interval [CI] 1.189-4.277, p = 0.013) and diabetes (OR = 4.156, 95% CI 1.571-10.999, p = 0.004) were independent predictors of 30-day postoperative complications. For patients undergoing bottom surgery, total operative time in minutes (OR = 1.005, 95% CI 1.003-1.007, p = 0.001) was an independent predictor of 30-day postoperative complications. Conclusion: The demand for GAS has increased exponentially since 2014. While postoperative complication rates are acceptable, Black race was shown to be an independent predictor of postoperative morbidity in patients undergoing top surgery, a finding that calls for further investigation of racial disparities among transgender patients.

Standards of Care for the Health of Transgender and Gender Diverse People, Version 8

Background: Transgender healthcare is a rapidly evolving interdisciplinary field. In the last decade, there has been an unprecedented increase in the number and visibility of transgender and gender diverse (TGD) people seeking support and gender-affirming medical treatment in parallel with a significant rise in the scientific literature in this area. The World Professional Association for Transgender Health (WPATH) is an international, multidisciplinary, professional association whose mission is to promote evidence-based care, education, research, public policy, and respect in transgender health. One of the main functions of WPATH is to promote the highest standards of health care for TGD people through the Standards of Care (SOC). The SOC was initially developed in 1979 and the last version (SOC-7) was published in 2012. In view of the increasing scientific evidence, WPATH commissioned a new version of the Standards of Care, the SOC-8. Aim: The overall goal of SOC-8 is to provide health care professionals (HCPs) with clinical guidance to assist TGD people in accessing safe and effective pathways to achieving lasting personal comfort with their gendered selves with the aim of optimizing their overall physical health, psychological well-being, and self-fulfillment. Methods: The SOC-8 is based on the best available science and expert professional consensus in transgender health. International professionals and stakeholders were selected to serve on the SOC-8 committee. Recommendation statements were developed based on data derived from independent systematic literature reviews, where available, background reviews and expert opinions. Grading of recommendations was based on the available evidence supporting interventions, a discussion of risks and harms, as well as the feasibility and acceptability within different contexts and country settings. Results: A total of 18 chapters were developed as part of the SOC-8. They contain recommendations for health care professionals who provide care and treatment for TGD people. Each of the recommendations is followed by explanatory text with relevant references. General areas related to transgender health are covered in the chapters Terminology, Global Applicability, Population Estimates, and Education. The chapters developed for the diverse population of TGD people include Assessment of Adults, Adolescents, Children, Nonbinary, Eunuchs, and Intersex Individuals, and people living in Institutional Environments. Finally, the chapters related to gender-affirming treatment are Hormone Therapy, Surgery and Postoperative Care, Voice and Communication, Primary Care, Reproductive Health, Sexual Health, and Mental Health. Conclusions: The SOC-8 guidelines are intended to be flexible to meet the diverse health care needs of TGD people globally. While adaptable, they offer standards for promoting optimal health care and guidance for the treatment of people experiencing gender incongruence. As in all previous versions of the SOC, the criteria set forth in this document for gender-affirming medical interventions are clinical guidelines; individual health care professionals and programs may modify these in consultation with the TGD person.

Robotic Peritoneal Flap vs. Perineal Penile Inversion Techniques for Gender-Affirming Vaginoplasty

PURPOSE OF REVIEW

To discuss perineal and robotic approaches to gender-affirming vaginoplasty.

RECENT FINDINGS

The Davydov peritoneal vaginoplasty has its origins in neovaginal reconstruction for vaginal agenesis. It has been adapted as a robotic-assisted laparoscopic procedure and provides an alternative to perineal canal dissection in gender-affirming vaginoplasty. Both techniques represent variations of penile inversion vaginoplasty with successful outcomes and overall low rates of major complications reported in the literature. However, there are differing advantages and considerations to each approach. A perineal approach has been the gold standard to gender-affirming vaginoplasty for many decades. Robotic peritoneal gender-affirming vaginoplasty (RPGAV) is an emerging alternative, with potential advantages including less reliance on extragenital skin grafts in individuals with minimal genital tissue, especially among patients presenting with pubertal suppression, and safer dissection in revision vaginoplasty for stenosis of the proximal neovaginal canal. Additional risks of RPGAV include those associated with robotic abdominal surgeries.
