Genital Hypoplasia in Gender-affirming Vaginoplasty: Prior Orchiectomy, Penile Length, and Other Factors to Guide Surgical Planning.

PURPOSE: Penile inversion vaginoplasty uses genital skin to construct the neovaginal canal. When genital skin is insufficient, extragenital tissue is needed. The purpose of this study is to evaluate which demographic factors and intraoperative anatomical measurements are associated with skin availability and the need for extragenital tissue. MATERIALS AND METHODS: This was a prospective cohort study of patients undergoing penile inversion vaginoplasty from May 2016 through January 2021. Preoperative variables included patient demographics, orchiectomy and circumcision status, and stretched penile and scrotal skin lengths. Outcomes included measurements of available scrotal skin surface area and need for extragenital skin graft. RESULTS: A total of 235 patients were included. Patients with prior orchiectomy and shorter stretched scrotal and penile lengths had less scrotal skin available (P < .002) and were more likely to require extragenital skin grafts (P < .001). Patients with prior orchiectomy had 3 times greater odds of needing additional skin grafts. Length of time exposed to gender-affirming hormones did not predict scrotal skin availability (P = .8). CONCLUSIONS: Factors associated with need for extragenital skin grafting with penile inversion vaginoplasty were prior orchiectomy and stretched penile skin length <8 cm. Scrotal skin length >10 cm was associated with low risk for needing additional graft. Considering these factors can help with preoperative planning and patient counseling.

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.

Neovaginal Canal Dissection in Gender-Affirming Vaginoplasty.

PURPOSE: Gender-affirming vaginoplasty creates the vulva and vaginal canal for individuals assigned male sex at birth who have gender dysphoria. Dissection of the neovaginal space can be particularly challenging, with risk of injury to the anal and urethral sphincters, urethra and rectum. We present an anatomically based technique for vaginal canal dissection. MATERIALS AND METHODS: We retrospectively analyzed a cohort of patients who underwent gender-affirming vaginoplasty by a single surgeon between May 2016 and July 2019. We describe our technique for dissection and report relevant outcomes. RESULTS: We performed 200 vaginoplasty procedures during the study period. Patient age ranged from 15-70 years (median 41). Body mass index ranged from 16-50.5 kg/m2 (median 27). The vaginal depth ranged from 10-16 cm, with a median of 14 cm and a mean of 13.7 cm. Vaginal depth was slightly greater for patients with a body mass index of ≥30 vs <30 kg/m2 (p=0.0145). Operative complications were observed in 2 patients (1.0%) with a full thickness rectal injury and in 3 (1.5%) with a partial thickness rectal injury. Two of these patients (1.0%) had progression to a rectovaginal fistula (1 full and 1 partial thickness injury), 1 patient (0.5%) had a urethral injury, 8 patients (4.0%) had vaginal stenosis, 3 patients (1.5%) had introital stenosis and 10 patients (5.0%) had stress urinary incontinence that later resolved. CONCLUSIONS: Neovaginal canal dissection in gender-affirming vaginoplasty is technically challenging. An anatomically based approach is associated with a low complication rate at our center.

Masculinizing Genital Surgery: An Imaging Primer for the Radiologist.

OBJECTIVE. Masculinizing genital surgeries for transgender individuals are currently performed at only a select few centers; however, radiologists in any geographic region may be confronted with imaging studies of transgender patients. The imaging findings of internal and external genital anatomy of a transgender patient may differ substantially from the imaging findings of a cisgender patient. This article provides the surgical and anatomic basis to allow appropriate interpretation of preoperative and postoperative imaging findings. We also expand on the most common complications and associated imaging findings. CONCLUSION. As these procedures become more commonplace, radiologists will have a growing role in the care of transgender patients and will be faced with new anatomic variants and differential diagnoses. Familiarity with these anatomic variations and postoperative complications is crucial for the radiologist to provide an accurate and useful report.

Robotic Davydov Peritoneal Flap Vaginoplasty for Augmentation of Vaginal Depth in Feminizing Vaginoplasty.

PURPOSE: Penile inversion vaginoplasty is the most common procedure for genital reconstruction in transwomen. While penile inversion vaginoplasty usually provides an excellent aesthetic result, the technique may be complicated by vaginal stenosis and inadequate depth, especially in transwomen with limited penile and scrotal tissue. We describe a technique of using peritoneal flaps to augment the neovaginal apex and canal in penile inversion vaginoplasty for transwomen. MATERIALS AND METHODS: Between 2017 and 2018 we identified 41 transwomen who underwent primary penile inversion and peritoneal flap vaginoplasty. Two approximately 6 cm wide by 8 cm long peritoneal flaps were raised from the anterior aspect of the rectum and the sigmoid colon, and the posterior aspect of the bladder to create the apex of the neovagina. RESULTS: Average ± SD age of the 41 patients was 34 ± 14 years. Average procedure duration was 262 ± 35 minutes and average length of stay was 5 days. Average followup was 114 ± 79 days. At the most recent followup vaginal depth and width were measured to be 14.2 ± 0.7 and 3.6 ± 0.2 cm, respectively. The peritoneal flap added an additional 5 cm of depth beyond the length of the skin graft, forming the vaginal canal in patients with limited scrotal skin. CONCLUSIONS: Penile inversion vaginoplasty remains the gold standard for primary genital reconstruction in transwomen. Peritoneal flaps provide an alternative technique for increased neovaginal depth, creating a well vascularized apex with acceptable anticipated complications.

Reconstructive Management Pearls for the Transgender Patient.

PURPOSE OF REVIEW: A growing number of transgender patients are seeking gender-affirming genital reconstructive surgery (GRS). These complex procedures have high complication rates. We describe common surgical pitfalls in GRS and approaches for minimizing complications. RECENT FINDINGS: Penile inversion vaginoplasty has been associated with excellent cosmetic and functional outcomes. A robotic-assisted dissection may minimize risk of rectal injury. As a younger transgender population chooses pubertal suppression, alternative sources for lining the vaginal canal, such as enteric vaginoplasties, may be more widely utilized. Since adoption of microvascular techniques in phalloplasty, transmasculine individuals have potential for a sensate neophallus and penetrative intercourse. Urethral complications are common and challenging to manage; techniques using flap coverage may minimize ischemia-related strictures. Innovations in prosthesis placement require adaptations to neophallus anatomy. A growing number of transgender individuals are seeking genital reconstruction. Ongoing innovation in surgical technique is needed to improve patient outcomes.

National Trends in Secondary Procedures Following Pediatric Pyeloplasty.

PURPOSE: Although reported success rates after pediatric pyeloplasty to correct ureteropelvic junction are high, failure may require intervention. We sought to characterize the incidence and timing of secondary procedures after pediatric pyeloplasty using a national employer based insurance database. MATERIALS AND METHODS: Using the MarketScan® database we identified patients 0 to 18 years old who underwent pyeloplasty from 2007 to 2013 with greater than 3 months of postoperative enrollment. Secondary procedures following the index pyeloplasty were identified by CPT codes and classified as stent/drain, endoscopic, pyeloplasty, nephrectomy or transplant. The risk of undergoing a secondary procedure was ascertained using Cox proportional hazards models adjusting for demographic and clinical characteristics. RESULTS: We identified 1,976 patients with a mean ± SD followup of 23.9 ± 19.8 months. Overall 226 children (11.4%) had undergone at least 1 post-pyeloplasty procedure. The first procedure was done within 1 year in 87.2% of patients with a mean postoperative interval of 5.9 ± 11.1 months. Stents/drains, endoscopic procedures and pyeloplasties were noted in 116 (5.9%), 34 (1.7%) and 71 patients (3.1%), respectively. Length of stay was associated with undergoing a secondary procedure. Compared with 2 days or less the HR of 3 to 5 and 6 days or greater was 1.65 and 3.94 (p = 0.001 and <0.001, respectively). CONCLUSIONS: Following pediatric pyeloplasty 1 of 9 patients undergoes at least 1 secondary procedure with the majority performed within the first year. One of 11 patients undergoes intervention more extensive than placement of a single stent or drain, requiring management strategies that generally signify recurrent or persistent obstruction. Estimates of pyeloplasty success in this national data set are lower than in other published series.

Exposure to and Attitudes Regarding Transgender Education Among Urology Residents.

INTRODUCTION: Transgender individuals are underserved within the health care system but might increasingly seek urologic care as insurers expand coverage for medical and surgical gender transition. AIM: To evaluate urology residents' exposure to transgender patient care and their perceived importance of transgender surgical education. METHODS: Urology residents from a representative sample of U.S. training programs were asked to complete a cross-sectional survey from January through March 2016. MAIN OUTCOME MEASURES: Respondents were queried regarding demographics, transgender curricular exposure (didactic vs clinical), and perceived importance of training opportunities in transgender patient care. RESULTS: In total, 289 urology residents completed the survey (72% response rate). Fifty-four percent of residents reported exposure to transgender patient care, with more residents from Western (74%) and North Central (72%) sections reporting exposure (P ≤ .01). Exposure occurred more frequently through direct patient interaction rather than through didactic education (psychiatric, 23% vs 7%, P < .001; medical, 17% vs 6%, P < .001; surgical, 33% vs 11%, P < .001). Female residents placed greater importance on gender-confirming surgical training than did their male colleagues (91% vs 70%, P < .001). Compared with Western section residents (88%), those from South Central (60%, P = .002), Southeastern (63%, P = .002), and Mid-Atlantic (63%, P = .003) sections less frequently viewed transgender-related surgical training as important. Most residents (77%) stated transgender-related surgical training should be offered in fellowships. CONCLUSION: Urology resident exposure to transgender patient care is regionally dependent. Perceived importance of gender-confirming surgical training varies by sex and geography. A gap exists between the direct transgender patient care urology residencies provide and the didactic transgender education they receive.

Second-stage Scrotoplasty with Autologous Tissue Augmentation after Metoidioplasty.

We present our technique for second-stage scrotoplasty with autologous tissue augmentation following gender-affirming metoidioplasty. This technique augments the scrotum while removing the upper labia majora and making the penis more visible and accessible. This procedure avoids the need for testicular prostheses and their potential for discomfort, displacement, extrusion, or infection. Our preliminary results show that the complication rate is low.

Gender-affirming Clitoroplasty and Construction of the Clitoro-urethral Complex: An Anatomy Guided Selection of Two Techniques.

OBJECTIVE: To present 2 clitoroplasty techniques-the preputial skin and urethral flap-and describe our rationale for using each technique to construct the clitoro-urethral complex in gender-affirming vaginoplasty. METHODS: For uncircumcised patients or circumcised patients with greater than 2 cm of inner preputial skin and at least 8 cm of shaft skin proximal to the circumcision scar, we use the preputial skin clitoroplasty, a modification of the Ghent style clitoroplasty. The entire corona is used after medial glans and urethral mucosa is excised. The corona is brought together 1 cm from midline to create the visible ovoid clitoris; the remaining coronal tissue remains lateral to the clitoris for erogenous sensation as clitoral corpora. The clitoris is anchored to the proximal tunica, positioned at the level of the adductor longus tendon. The folded neurovascular bundle is fixed in the suprapubic area. The ventral urethral is spatulated and urethral flap approximated to the clitoris. Preputial skin is sutured proximally as tension allows. The clitoro-urethral complex is inset into an opening created in the penile skin flap. For patients with less skin, we use the urethral flap clitoroplasty. More corpus spongiosum is used, as the urethra creates the clitoral hood; this is described in the literature and attributed to Pierre Brassard. The clitoris is inset following a dorsal urethrotomy, with a small collar of preputial skin sewn to the spongiosum and urethral mucosa. The urethra is transected about 1 cm distally. The ventral urethra is then spatulated and the urethroplasty completed. RESULTS: We prefer the preputial skin flap technique for its' greater coronal tissue volume for erogenous sensation and better esthetics, in our opinion. Circumcised patients should have at least 2 cm of skin distal to the circumcision scar. To avoid using skin graft for the introitus-a risk for introital stenosis-shaft skin proximal to the circumcision line should be at least 8 cm. CONCLUSION: We present 2 technical options for clitoroplasty and construction of the clitoro-urethral complex in gender-affirming vaginoplasty.

Urinary Reconstruction in Genital Gender-Affirming Surgery: Checking Our Surgical Complication Blind Spots.

BACKGROUND: Urologic complications in genital gender-affirming surgery are imperfectly measured, with existing evidence limited by "blind spots" that will not be resolved through implementation of patient-reported outcomes alone. Some blind spots are expected in a surgical field with rapidly expanding techniques, and they may be exacerbated by factors related to transgender health. METHODS: The authors provide a narrative review of systematic reviews published in the past decade to describe the current options for genital gender-affirming surgery and surgeon-reported complications, as well as contrasting peer-reviewed sources with data not reported by the primary surgeon. In combination with expert opinion, these findings help estimate complication rates. RESULTS: Eight systematic reviews describe complications in patients undergoing vaginoplasty, including 5% to 16.3% mean incidence of meatal stenosis and 7% to 14.3% mean incidence of vaginal stenosis. Compared with surgeon-reported cohorts, patients undergoing vaginoplasty or vulvoplasty in other reports had higher rates of voiding dysfunction (47% to 66% versus 5.6% to 33%), incontinence (23% to 33% versus 4% to 19.3%), or misdirected urinary stream (33% to 55% versus 9.5% to 33%). Outcomes in six reviews of phalloplasty and metoidioplasty included urinary fistula (14% to 25%), urethral stricture or meatal stenosis (8% to 12.2%), and ability to stand to void (73% to 99%). Higher rates of fistula (39.5% to 56.4%) and stricture (31.8% to 65.5%) were observed in alternate cohorts, along with previously unreported complications such as vaginal remnant requiring reoperation. CONCLUSIONS: The literature does not completely describe urologic complications of genital gender-affirming surgery. In addition to standardized, robustly validated patient-reported outcome measures, future research on surgeon-reported complications would benefit from using the IDEAL (idea, development, exploration, assessment, and long-term study) framework for surgical innovation.

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.

Optimizing aesthetics in gender-affirming vaginoplasty and vulvoplasty: a narrative review and discussion based on over 600 cases of transfeminine vulvar construction.

Background and Objective: The vulva is the external portion of a gender-affirming vaginoplasty or vulvoplasty procedure-the "visible" result of surgery. The vulvar appearance can play a major role in how individuals feel about their surgical results and new genital anatomy. Therefore, optimizing the aesthetics of the vulva is an important component of surgical care. Although there is no one "ideal" vulvar appearance, aesthetics are optimal when each major sub-unit of the vulva is reconstructed to create a proportional and cohesive vulvar unit. In this article we perform a narrative review of the literature and discuss clinical approaches to improve aesthetic satisfaction such as patient education, re-defining the "ideal" vulva, aesthetic surgery tenets and technical strategies based on our collective experience of over 630 gender-affirming vulvar constructions. Methods: A narrative review of the literature was completed accessing PubMed, EMBASE, Google Scholar using search terms "Vaginoplasty OR Vulvoplasty". Articles were removed if not pertaining to gender affirmation surgery, were not in English language, were not accessible or did not discuss aesthetics in the body of the text. Key Content and Findings: A total of 1,042 articles were identified from initial search criteria. Of those, 905 were excluded as they did not involve gender affirmation as an indication. An additional 112 papers were excluded as they were not accessible, not in English, focused on non-vulvar outcomes or did not comment on vulvar aesthetics. Ultimately 25 articles were included for narrative review; 21 of these included technical descriptions of vulva and 13 had direct aesthetic discussion. The anatomy and aesthetics of the transfeminine vulva are reviewed according to the previously described principle of anatomic vulvar sub-units: the labia majora, labia minora, clitoris, urethra and the introitus. Conclusions: Ultimately, creating the optimal vulva for each individual patient will demand flexible surgical decisions based on individual anatomy and available tissues. This narrative review provides an overview of current approaches to aesthetics in gender-affirming vulvar construction and technical insights based on our institutional experience of performing over 630 gender-affirming vaginoplasty and vulvoplasty procedures.

A Content and Readability Analysis of Genitourinary and Sexual Health-Related Patient-Reported Outcome Measures in Gender-Affirming Care.

OBJECTIVE: To the evaluate the readability and comprehensiveness of genitourinary and sexual health-related patient-reported outcomes (PROMs) used in gender-affirming care. METHODS: Common PROMs that measure genitourinary and sexual health-related outcomes in gender-affirming care literature were identified from six recent systematic reviews. Readability analysis was completed at the level of individual items and full scale using established readability assessment tool, including Flesch Kincaid Grade Level (FKGL), Gunning Fog Score (GF), Coleman Liau Index (CLI), and Simple Measure of Gobbledygook (SMOG) Index. The concepts measured by the PROMs were evaluated for comprehensiveness. RESULTS: Twenty-five PROMs were included, of which 12 assessed genitourinary outcomes and 13 assessed sexual health outcomes. A total of seven genitourinary domains and eight sexual health domains were identified during concept mapping. Readability analysis showed a median PROM grade level of 9.0 and 9.5 in genitourinary and sexual PROMs, respectively. The Patient-Reported Outcomes Measurement Information System Sexual Function and Satisfaction v2.0 had the lowest median reading grade level of 5.7, and the Female Sexual Function Index has the highest median reading grade level of 13.9. No single PROM was found to be comprehensive. Multiple PROMs contained double-barreled items or used outdated terminology. CONCLUSION: Most PROMs used in the genital gender-affirming literature failed to meet the readability recommendations for patient-facing material and were culturally unfit for use in transgender and gender-diverse individuals. None of the PROMs were found to be comprehensive for evaluating outcomes of gender-affirming care. Validated gender-affirming care-specific PROMs that are comprehensible, comprehensive, and relevant are urgently needed.

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.

Management of Urologic Complications After Genital Gender-Affirming Surgery in Transgender and Nonbinary Patients.

Transgender and nonbinary (TGNB) patients are a population with unique urologic needs that are often overlooked in urologic training. Most urology residents think that learning to take care of this population is important in their training; however, there is much variation in this educational content within urology residency programs. This review provides information on the current state of teaching regarding the unique needs of caring for TGNB patients as urologists and overviews some basic principles that every urologist should know.
