RESUMO

BACKGROUND: Transgender men (TM) seeking gender-affirming phalloplasty and transgender women (TW) seeking vaginoplasty and desiring insertive intercourse must consider penis size. Evidence has shown that, at least among cisgender men (CM), penile dimensions tend to be poorly estimated. In transgender patients desiring gender-affirming surgery, inaccuracy in estimation of penis dimensions may lead to unnecessary morbidity: for TW, trauma to the neovagina; for TM with excess girth, an inability to insert. Studies on the accuracy with which transgender and cisgender patients estimate penis size are limited. AIM: To assess the degree of accuracy with which CM and CW, as well as TM and TW, visually estimate the size of the human penis, including length, width, and girth. METHODS: There were 142 participants included (25 TM, 47 TW, 30 CM, and 40 CW; net mean ± SD age, 36.6 ± 11.2 years). Participants were shown these models and asked to estimate length, width, and midshaft girth by visual inspection of 6 realistic models of a penis and scrotum of varying lengths and widths. We evaluated the accuracy of the visual measurements by comparing mean perceived dimensions with the actual dimensions of each model. OUTCOMES: We used a multivariate model of all 3 bias dimensions to test for differences in average bias among gender groups (CM, CW, TM, and TW). RESULTS: TM significantly overestimated length across the longest models. TW significantly overestimated length in the longer 3 models. All groups except for TM significantly underestimated girth in at least 1 model. No groups significantly underestimated width. CM, CW, and TM significantly overestimated width in all 6 models. CLINICAL IMPLICATIONS: When transgender patients use numbers to express penis size (either in neophallus or vaginal depth based on perceived partner size), the result is likely to be larger than expected. Use of realistic penis models as a decision-making tool may help manage patient expectations and surgery decision making preoperatively and improve postoperative patient satisfaction and safety. STRENGTHS AND LIMITATIONS: To our knowledge, this is the first study to assess visual estimation in penis size in TM and CM, as well as TW and CW. The penile models in our study were shown side by side and in the flaccid state despite having dimensions more consistent with an erect penis, which may have influenced estimations across all dimensions. CONCLUSION: Men and women (cisgender and transgender) tend to significantly overestimate penis length and width.

RESUMO

BACKGROUND: Shallow-depth vaginoplasty (SDV), also referred to as vaginoplasty without creation of a vaginal canal, is an understudied alternative to full-depth vaginoplasty (FDV), or vaginoplasty with creation of a vaginal canal. SDV is associated with fewer short- and long-term risks and shorter recovery, and does not require a lifelong commitment to vaginal dilation and douching. AIM: To describe a surgical technique for SDV that creates a dimpled introitus, together with clinical outcomes, decision-making prioritization, and satisfaction data. We hypothesize that SDV patients prioritize comparable appearance and sexual function to FDV over shorter-term risk factors, and experience high satisfaction. METHODS: We describe (1) a surgical technique for SDV; (2) the proportion of patients who underwent SDV vs. FDV, with SDV complication rates; and (3) the results of an anonymous, electronic questionnaire administered via Qualtrics that assessed SDV patient demographics, terminology preferences, prioritization of decision-guiding factors for choosing SDV over FDV, and postoperative satisfaction across various domains. OUTCOMES: A total of 110 patients underwent primary feminizing genital gender-affirming surgery at a single institution between April 2017 and July 2022: 35 (32%) of 110 underwent SDV and 75 (68%) underwent FDV. The 35 SDV patients were invited to answer the study questionnaire, of which 29 (83%) completed it (mean age 51.9 ± 16.7 years, mean body mass index 27.3 ± 5.3 kg/m2). RESULTS: All but one survey respondent met one or more of the following characteristics: (1) ≥40 years of age, (2) exclusively feminine-identifying sexual partners, and/or (3) significant aversion to performing long-term vaginal dilation and douching. Ranking of 8 decision-guiding factors revealed prioritization of long-term over short-term outcomes. Postoperatively, patients reported high satisfaction across all 3 domains. When asked if they had to choose between SDV and FDV over again, 86% reported that they would choose SDV. While 14% would choose FDV, all but one reported new interest in receptive vaginal intercourse due to finding masculine-identifying partners post-SDV surgery. A total of 27% of SDV patients experienced complications that required additional surgeries; 82% of complications were related to urinary spraying. CLINICAL IMPLICATIONS: SDV is a lower-risk alternative to FDV and is associated with reduced postoperative maintenance and high postoperative satisfaction. STRENGTHS AND LIMITATIONS: This study describes the clinical outcomes of the largest documented cohort of patients to undergo SDV to date. Limitations include recall bias due to the retrospective survey and use of nonvalidated questions attributed to the paucity of validated gender-affirming surgery questionnaires. CONCLUSION: SDV's appeal to a large subset of patients (32% in this study), low complication rate, high satisfaction, and low decisional regret suggests that this surgical option should be offered to all patients seeking feminizing genital gender-affirming surgery.

RESUMO

BACKGROUND: One challenge in transgender research is reliably identifying patients through electronic medical records data, as there is no universal transgender International Classification of Diseases (ICD) code, but rather multiple ICD codes that can be used. AIM: To explore the sensitivity and specificity of 5 commonly used ICD codes to identify transgender patients overall and transgender women specifically (assigned male sex at birth) by using data from the Veterans Affairs (VA), the largest integrated health system in the United States. METHODS: Patients aged ≥18 years were identified via ICD-9 codes 302.5 and 302.6 (Ninth Revision) and ICD-10 codes F64.0, F64.8, and F64.9 (Tenth Revision) using VA health records from 2000 to 2021 and stratified by bilateral orchiectomy status. OUTCOMES: Detailed chart review was performed on 32 randomly selected patients for each code (half with and half without orchiectomy) to confirm transgender status and to perform descriptive analyses. RESULTS: For each ICD code, rates of confirmed transgender status ranged from 88% to 100% for those with and without an orchiectomy, with the majority being transgender women (consistent with most veterans being assigned male sex at birth). Most transgender women (66%-100%) were undergoing estrogen gender-affirming therapy. The majority of provider-driven entries of transgender status took place from 2011 to 2020, with 75% of entries made from 2011 to 2020, consistent with increased recognition and societal acceptance of this population. False negatives were detected at a rate of 15%. Based upon these 5 ICD codes alone, we estimate that the VA has records for 9,449 to 10,738 transgender individuals. CLINICAL IMPLICATIONS: All 5 codes are very sensitive in identifying transgender patients, and the combination of these codes with orchiectomy is extremely sensitive in identifying transgender women, specifically. STRENGTHS AND LIMITATIONS: Major strengths of the study are the use of universal ICD codes and a large patient sample size that spans health records nationally and across multiple decades, potentially making our data more generalizable. The main limitation of this study is that subanalyses were performed on a limited number of patients, which prevented us from capturing all false positives and thus from calculating specificity for each code. Similarly, our true negatives were derived from a small, random subset of the population; as such, our calculation for specificity is an estimate. CONCLUSION: This study highlights a novel method to identify transgender women and paves the way for further research.

RESUMO

BACKGROUND: The effects of male circumcision on sexual function remain controversial. Heterogeneity across previous studies and low-quality scientific evidence have resulted in poor understanding of the effects of circumcision on erogenous sensation of the penis and orgasm function. AIM: In this study we sought to describe and assess differences in erogenous genital sensation and reported orgasm function in circumcised compared with uncircumcised men. METHODS: Adult male subjects who were recruited on a paid anonymous online survey platform were shown illustrations of 12 anatomic regions of the penis. Subjects were prompted to designate regions as pleasurable when touched during partnered sex and to rate each on a 1-10 scale, with higher erogeneity scores correlating with greater pleasure. Subjects were also asked to characterize their orgasms across 6 experiential domains. OUTCOMES: Outcomes were differences between circumcised and uncircumcised men in the probabilities that regions would be designated as pleasurable, average pleasure scores, and self-reported orgasm parameters. RESULTS: In total, 227 circumcised (mean [SD] age 46.6 [17.7] years) and 175 uncircumcised men (47.8 [18.1] years) completed the survey. There were no significant differences in average ratings across all regions between circumcised and uncircumcised men. However, significantly more circumcised men reported preferences for the tip of the penis (38% vs 17%, P = .02) and the middle third of the ventral penile shaft (63% vs 48%, P = .04). Additionally, there were no significant differences in orgasm quality and function across all queried domains between circumcised and uncircumcised cohorts. CLINICAL IMPLICATIONS: Our findings suggest that circumcision does not change how men describe erogenous genital sensation or how they experience orgasm. STRENGTHS AND LIMITATIONS: In this study we expanded upon existing literature regarding comparison of sexual function in circumcised and uncircumcised men in its scale and investigation of diverse domains. Limitations include the survey format of data collection. CONCLUSION: We found no differences in reported erogenous ratings or orgasm function between circumcised and uncircumcised men. These findings suggest that male circumcision does not negatively impact penile erogeneity or orgasm function.

RESUMO

BACKGROUND: To date, a comprehensive state-by-state assessment of transgender transition-related health care coverage for gender-affirming hormone therapy (GAHT) and genital gender-affirming surgery (GAS) has not been reported. AIMS: The aims of this study were 1) to verify which U.S. states' Medicaid systems do/do not cover GAHT and GAS; 2) to assess the ease/difficulty for patients to determine whether GAHT and GAS are Medicaid-covered benefits; and 3) to understand possible state-related predictors of Medicaid coverage for gender-affirming care. METHODS: We reviewed the official Medicaid Handbook and website for all 51 states (+D.C.) and 5 territories to confirm whether GAHT and GAS are covered benefits. When indeterminate, we called the Medicaid office in each state, and for many, Medicaid managed care organizations (MCOs), and individual in-state providers, to confirm coverage. We recorded our experiences, number of, and duration of phone calls to confirm coverage. OUTCOMES: The main outcome was a definitive answer from the state/territory's Medicaid program or MCOs regarding whether GAHT and GAS are/are not covered benefits. Secondary outcome measures included responses we received and the total number/duration of phone calls necessary to confirm coverage. RESULTS: Only 12 of 51 states and 0 of 5 territories featured their policy regarding coverage for GAHT in their Medicaid Handbook/webpages. We confirmed that 34 of 51 state Medicaid programs do cover GAHT, whereas 9 of 51 states' and 2 of 5 territories' do not. We could not confirm coverage of GAHT in 8 of 51 states and 3 of 5 territories. Only 26 of 51 states and 0 of 5 territories featured their policy regarding coverage for GAS in their Medicaid Handbook/webpages. We confirmed that 25 of 51 state Medicaid programs do cover GAS, whereas 22 of 51 states' and 3 of 5 territories' do not. We could not confirm coverage of GAS in 4 of 51 states and 2 of 5 territories. Up to 12 calls, lasting up to 125 minutes, were required to confirm coverage for GAHT/GAS. CLINICAL IMPLICATIONS: Our findings indicate that important health care access barriers/disparities exist today and warrant improvement. STRENGTHS & LIMITATIONS: To our knowledge, this is the most comprehensive assessment of transgender transition-related health care coverage. Limitations include possible bias, as it could be that we were more persistent than actual patients would be to determine service coverage, and a lack of specificity regarding which specific hormone formulations or procedures are/are not covered. CONCLUSION: Our findings show that only 34 of 51 (67%) states' Medicaid programs include GAHT and 25 of 51 (49%) include GAS as covered benefits. Our experience suggests that the process to confirm coverage can be especially time-consuming and frustrating for patients. Zaliznyak M, Jung EE, Bresee C, et al.

RESUMO

INTRODUCTION: Various methods have been described to create a functional neovagina with feminizing (male-to-female) gender affirming surgery. Intestinal vaginoplasty using ileal or colon segments confers natural mucus production and greater canal depth with primary vaginoplasty. In this work we describe an alternative approach to primary and salvage vaginoplasty using right colon. We focus on relative advantages compared to use of other bowel segments, and we review patient outcomes. METHODS: Transgender women who had previously undergone primary vaginoplasty underwent laparoscopic right colon vaginoplasty at our center between 12/2017 and 7/2019. Demographic, medical, outcome, and satisfaction data was collected and retrospectively reviewed. RESULTS: Twenty-two consecutive transgender women patients underwent laparoscopic right colon vaginoplasty. Mean age was 39.3 years. There were two intraoperative complications:1 injury of the ileocolic pedicle, and 1 minor bladder injury. Four of 22 patients (18.2%) had short-term complications (< 30 days): 3 had postoperative ileus/small bowel obstruction and 1 had intra-abdominal hemorrhage. All were managed conservatively. Six of 22 patients (27.3%) experienced a total of 14 long-term complications (> 30 days): 1 developed Crohn's (not involving the neovagina); 1 developed late small bowel obstruction (SBO) (managed conservatively); 5 developed neovagina prolapse; 4 developed stenosis (2 at the vaginal introitus, and 2 had extrinsic obstruction at the recto-vaginal junction (all underwent successful laparoscopic surgical correction); and 3 were diagnosed with diversion neovaginitis (all treated conservatively). All complications were successfully treated with conservative and/or surgical intervention. All (100%) patients reported satisfaction with neovagina function and appearance. CONCLUSION: This is the only outcomes series of transgender women patients who have undergone right colon vaginoplasty, to date. Our study finding suggests that laparoscopic right colon for primary or salvage vaginoplasty has several important advantages over use of Sigmoid colon or Ileum, and is a reliable technique whose complications can be managed successfully, with favorable, satisfactory long-term outcomes.

RESUMO

It has been proposed that men hospitalised with COVID-19 be treated with oestrogen or progesterone to improve COVID-19 outcomes. Transgender women (male-to-female) are routinely treated with oestrogen or oestrogen +progesterone for feminisation which provides a model for the effect of feminising hormones on testicular tissue. Our goal was to analyse differences in ACE-2 expression in testicles of trans-women taking oestrogen or oestrogen +progesterone. Orchiectomy specimens were collected from trans-women undergoing gender-affirming surgery, who were taking oestrogen or oestrogen+progesterone preoperatively. For controls, we used benign orchiectomy specimens from cis-gender men. All specimens were stained with H&E, Trichrome (fibrosis), insulin-like 3 antibody (Leydig cell) and ACE-2 IHC. Cells per high-powered field were counted by cell type (Leydig, Sertoli and Germ). Stain intensity was rated on a 0-2 scale. On immunohistochemistry staining for Leydig cells and ACE-2 staining, the oestrogen+progesterone cohort had fewer Leydig cells compared with controls. The oestrogen+progesterone cohort also had greater degree of tissue fibrosis compared with controls and the oestrogen cohort. This work supports the hopeful possibility that a short course of progesterone (or oestrogen+progesterone) could downregulate ACE-2 to protect men from COVID-19 infection.

RESUMO

Understanding early events of HIV transmission within mucosal tissues is vital for developing effective prevention strategies. Here, we report that primary stromal fibroblasts isolated from endometrium, cervix, foreskin, male urethra, and intestines significantly increase HIV infection of CD4+ T cells-by up to 37-fold for R5-tropic HIV and 100-fold for X4-tropic HIV-without themselves becoming infected. Fibroblasts were more efficient than dendritic cells at trans-infection and mediate this response in the absence of the DC-SIGN and Siglec-1 receptors. In comparison, mucosal epithelial cells secrete antivirals and inhibit HIV infection. These data suggest that breaches in the epithelium allow external or luminal HIV to escape an antiviral environment to access the infection-favorable environment of the stromal fibroblasts, and suggest that resident fibroblasts have a central, but previously unrecognized, role in HIV acquisition at mucosal sites. Inhibiting fibroblast-mediated enhancement of HIV infection should be considered as a novel prevention strategy.

RESUMO

PURPOSE: We evaluated whether placement of a retropubic urethral sling fashioned from autologous vas deferens during robotic assisted radical prostatectomy would improve recovery of continence. MATERIALS AND METHODS: In a phase 2, single blind trial age stratified patients were randomized to undergo robotic assisted radical prostatectomy by multiple surgeons with or without sling placement. The outcomes were complete continence (0 urinary pads of any type) and near continence (0, an occasional or 1 pad per day) at 6 months, which was assessed by the Fisher exact test and logistic regression. The Kaplan-Meier method and the log rank test were used to evaluate time to continence. EPIC-UIN (Expanded Prostate Cancer Index Composite-Urinary Inventory) and I-PSS (International Prostate Symptom Score) 1, 3 and 6 months after catheter removal were evaluated by mixed models for repeated measures. RESULTS: Of 203 patients who were recruited 95 and 100 were randomized to undergo sling and no sling placement, respectively, and completed postoperative interviews. Six months after surgery the proportions reporting complete and near continence (66% and 87%, respectively) and times to complete and near continence were similar in the groups. Younger age was associated with a higher likelihood of complete continence (OR 1.74 per decreasing 5-year interval, 95% CI 1.23-2.48, p <0.01) and near continence (OR 2.18 per decreasing 5-year interval, 95% CI 1.21-3.92, p <0.01) adjusting for clinical, urinary and surgical factors. Adjusted EPIC-UIN and I-PSS scores changed with time but did not differ between the groups. No serious adverse events were observed. CONCLUSIONS: This trial failed to demonstrate a benefit of autologous urethral sling placement at robotic assisted radical prostatectomy on early return of continence at 6 months. Continence was related to patient age in adjusted models.

RESUMO

BACKGROUND: In our practice we have encountered 4 female-to-male transgender patients seeking neophallus revision surgery for girth precluding penetrative vaginal or anal intercourse. Despite this, there is little evidence available to guide transitioning patients in neophallus sizing. In this work we examined the dimensions of bestselling realistic dildos, presuming that the most popular dimensions would reflect population preferences for penetrative toys and phalluses. AIM: To determine a maximal upper limit for girth compatible with penetrative intercourse based on measurements of bestselling realistic dildos and published erect penile dimensions. METHODS: We collected measurements for "realistic dildos" designated as bestsellers for the top 5 Alexa.com-rated online adult retailers in the United States and for Amazon.com. We compared these with measurements of dildos available at Good Vibrations in San Francisco and with studies of erect natal dimensions. We compared all data with measurements of 4 index patients whose neophallus girth prevented penetrative intercourse. OUTCOMES: Length and circumference of overall bestselling and largest bestselling realistic dildos as reported on top websites and measured by investigators. RESULTS: The average insertive length of the compiled dildos (16.7 ± 1.6 cm) was 1 SD longer than natal functional erect penile length as reported in the literature (15.7 ± 2.6 cm); however, their average circumference (12.7 ± 0.8 cm) mirrored natal erect penile girth (12.3 ± 1.3). The average girth of vendors' top 3 largest-girth dildos was 15.1 ± 0.9 cm, 2 SD wider than natal erect penile girth. Index patients had an average length of 16.3 ± 3.2 cm and an average girth of 17.6 ± 1.3 cm. Index patient girth was 4 to 5 SD wider than the average natal erect girth. CLINICAL IMPLICATIONS: Based on our data, we suggest that a surgically created neophallus should have a girth no wider than 15.1 cm after implantation of an inflatable penile prosthesis. This corresponds to 2 SD wider than the average natal man's erect girth. STRENGTHS AND LIMITATIONS: Strengths include in-person measurements of patients whose girth prevented penetrative intercourse, the large number of dildos assessed, and correlations with in-person measurements. Limitations include the inability to account for the pliability of different materials, whether dildos were used for vaginal and/or anal insertion, the limited sample of 4 transmen for in-person measurement, and the absence of implanted inflatable penile prostheses in index neophalluses. CONCLUSIONS: Neophallus girth wider than 15.1 cm could lead to difficulty in penetrative intercourse for many individuals. A conservative recommendation for neophallus girth is 13 to 14 cm, or 0.5 to 1.5 SD wider than natal erect penile girth. Isaacson D, Aghili R, Wongwittavas N, Garcia M. How Big is Too Big?

RESUMO

Most preclinical and clinical, animal, and human research has been biased with respect to sex and even more so with respect to gender. In fact, little is known about the impact of sex and even less about the influence of gender on overall metabolic processes. The National Institutes of Health has recognized this gap in scientific knowledge and now mandates that studies be conducted in both sexes and to include gender as variables influencing physiological processes such as metabolism. It is therefore critical to understand and appreciate how to incorporate sex and gender in preclinical and clinical research in order to enhance our understanding of the mechanisms by which metabolic processes differ by sex and gender. In this chapter, we define sex and gender and discuss when sex and gender are not aligned, such as that which occurs in transgender individuals, and how this impacts metabolic processes. We discuss the importance of understanding the influence and interactions between sex hormones and sex chromosomes rather than focusing on their relative contributions to metabolism in isolation. This knowledge will optimize therapies specific for individuals which need to encompass sex and gender.

RESUMO

OBJECTIVES: To analyse the predictive factors for worse pathological outcome (muscle invasive pT2+, non-organ-confined pT3+ or N+ and histological Grade 3) of upper tract urothelial carcinoma (UTUC) in a Chinese population from a nationwide high-volume centre in China. PATIENTS AND METHODS: Predictors were studied by retrospectively reviewing the clinicopathological data of 729 consecutive patients with UTUC treated in our centre from January 2002 to December 2010. Univariate and multivariate logistic regression analyses were used. RESULTS: There were more female patients (56.4%) than males and more tumours were located in the ureter (52.7%) than in the pelvis. In multivariate analysis, male gender (hazard ratio [HR] 1.898, P = 0.001), sessile architecture (HR 3.249, P < 0.001), high grade (HR 5.007, P < 0.001), ipsilateral hydronephrosis (HR 4.768, P < 0.001), renal pelvis location (HR 2.620, P < 0.001) and tumour without multifocality (HR 1.639, P = 0.028) were predictive factors for muscle-invasive UTUC. Male gender (HR 2.132, P < 0.001), renal pelvis location (HR 3.466, P < 0.001), tumour without multifocality (HR 2.532, P = 0.001), sessile tumour architecture (HR 3.274, P < 0.001), and high grade (HR 3.019, P < 0.001) were predictive factors for non-organ-confined disease. Chronological old age (HR 1.047, P < 0.001), sessile tumour architecture (HR 25.192, P < 0.001), ipsilateral hydronephrosis (HR 1.689, P = 0.024), and positive urinary cytology (HR 1.997, P = 0.006) were predictive factors for histological Grade 3 UTUC. CONCLUSIONS: There was a predominance of female patients and ureteric tumours in UTUCs of this Chinese population. Male gender, sessile architecture, tumour location, tumour without multifocality, high histological grade and preoperative ipsilateral hydronephrosis were independent predictive factors for worse pathological outcome of UTUCs.

RESUMO

Background: As the number of gender-affirming procedures performed in the United States increases, physicians caring for gender-nonconforming patients, regardless of practice location and focus, will likely encounter transgender women with breast implants. Increasingly, transgender women are seeking breast feminization. However, this population is less consistently receiving surveillance and routine breast care than cisgender women. Aim: This report aims to add to the growing body of knowledge addressing breast augmentation complications in transgender women and to highlight disparities in healthcare. Methods: A case of breast implant-associated seroma at our institution was analyzed through chart review. A literature review was conducted using PubMed to gather all articles discussing breast implant-associated fluid collections in transgender patients. Prior to publication of this report, a Waiver of Consent was granted by the E.R.'s Institutional Review Board for the study under which this article was prepared. Results: Our patient was an African American transgender woman presenting initially at age 60 with significant asymmetry due to dramatic swelling of her left breast. The patient underwent bilateral breast augmentation outside of the United States 2 decades prior. The patient noted a gradual painless increase in her left breast size starting 3 years prior. She admitted that she was hesitant to seek a second opinion after being treated dismissively by another surgeon. Subsequent management included mammography and mirrored recommendations for late breast implant-associated seromas in cisgender patients: ultrasound, aspiration for cytology and culture, and removal of the implant and capsule. Outcomes: The fluid collection in our patient was determined to be a chronic hematoma and was managed surgically. Though this patient eventually achieved a good outcome, treatment was delayed due to barriers she faced as a transgender woman. Clinical Implications: Literature demonstrates that recommended management of late-onset breast-implant-associated seroma does not differ based on gender identity; however, transgender and GNC adults are more likely to receive less thorough care than cisgender women. Any patients undergoing breast augmentation with implants should be routinely evaluated for late complications, including seromas, which require prompt attention and methodical evaluation due to their potentially malignant nature. Strengths and Limitations: This article is limited in that it is a single report of breast seroma. It is strengthened by a PubMed review gathering all articles discussing breast-implant-associated fluid collections in transgender patients. Conclusion: We propose better education of physicians on how to care for transgender and gender-diverse patients should help mitigate the neglect and late presentation of such medical conditions in this vulnerable and marginalized population.

RESUMO

OBJECTIVE: To assess the reported changes in orgasm quality and function of transgender men (TM) and transgender women (TW) after commencing gender-affirming hormone therapy (GAHT). METHODS: We queried potential changes in orgasm function before and after commencing GAHT (minimum 1 year) among 130 consecutive TW and 33 TM. We queried the following domains under a uniform condition (masturbation): (1) Lead-time to reach orgasm, (2) Duration of orgasm, (3) Body location of orgasm sensation, (4) Description of orgasm as either a single or multiple-peak event, (5) Duration of post-orgasm refractory period, and (6) Overall satisfaction with orgasm quality. RESULTS: Within groups by gender, TW and TM reported similar responses to our inventory before starting GAHT. After commencing GAHT, TW reported notable changes in orgasm function: increase in lead-time necessary to reach orgasm, orgasm duration, and overall orgasm satisfaction. Similarly, TM reported an increase in duration of orgasm and increased overall satisfaction with orgasm quality. Over half of the TW reported experiencing orgasms in new/additional body locations. Additionally, prior to commencing GAHT, the majority of TM and TW patients reported their orgasms as a short, single-peak event but following GAHT these same patients reported longer and protracted multiple-peak orgasms. CONCLUSIONS: GAHT has the potential to positively improve orgasm quality for transgender patients undergoing gender transition. It is important to share such data with patients prospectively before treatments.

RESUMO

Few transgender-specific cancer screening recommendations exist. This review aims to cover current guidelines and practice patterns of cancer screening in transgender patients and, where evidence-based data are lacking, to draw from cisgender screening guidelines to suggest best practices for transgender patients based on anatomic inventory. Sufficient evidence does not exist to determine the long-term effects of gender-affirming hormone therapy on cancer risk. In the future, cancer screening and prevention should be focused on anatomic inventory and high-risk behaviors.

RESUMO

CONTEXT: Approximately 0.4-1.3% of the worldwide population is transgender. Although the exact prevalence is unknown, there is an increase in open identification as transgender. Among transgender women (TW), the prostate is retained even after gender-affirmation surgery, thus necessitating ongoing screening for prostate cancer (CaP). However, little is known about CaP screening in this population. OBJECTIVE: To assess our current understanding of CaP incidence and prostate-specific antigen (PSA) screening in TW. EVIDENCE ACQUISITION: We performed a nonsystematic narrative review of all PubMed publications through June 2022 according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. Given the limited primary research on this subject, case reports were also included. Studies were reviewed to understand PSA screening practices and reports of CaP in this population, as applicable. EVIDENCE SYNTHESIS: There is no consensus regarding PSA screening in TW from any of the major societies, and TW are largely absent from guidelines. Case report data suggest that TW with CaP may have more aggressive disease, and these cancers may have been pre-existing prior to present before gender-affirming hormone therapy (GAHT) or be castrate-resistant. CONCLUSIONS: We are in the infancy of our understanding of PSA screening in TW. Important avenues for future research include understanding the risks/benefits of PSA screening in TW, how best to mitigate potential negative psychological effects of PSA screening in TW, establishing baseline PSA values for those on GAHT (and determining what values should be considered "elevated"), establishing when to initiate PSA screening for those on GAHT, and establishing the accuracy of biomarkers for those undergoing GAHT. PATIENT SUMMARY: We examined patterns of prostate cancer screening for transgender women. Little is known about prostate cancer incidence or screening in this population. Additional research is needed to establish guidelines for screening in this population.

RESUMO

Background: Reconstructive urologists often place both a urethral and suprapubic catheter intraoperatively to prevent extravasation of undrained urine across anastomosis sutures. As no consensus exists on which catheter drains the bladder more completely, many surgeons leave one catheter to gravity drainage and cap the other postoperatively. We sought to identify differences in catheter urine outflow during dual bladder drainage with suprapubic and urethral catheters in postoperative urology patients. Methods: Urine output (UOP) from transgender men who underwent Stage II Phalloplasty with urethral lengthening was retrospectively reviewed. Both 16 French urethral and suprapubic catheters were placed to gravity drainage postoperatively. Urine output from each catheter was recorded separately, twice daily. Mixed model regression modeling tested for differences in urine output by time of day (day/night) and activity status (Bedrest: Postop Day 0-2, Ambulatory: Postop Day 3+). Results: The aggregate number of 12-hour shift urine output observations was 250 (125 for urethral and 125 for suprapubic catheters) across 14 inpatients. Suprapubic catheters had a mean 410 ml higher output than urethral catheters per 12-hour shift (p=0.002; 95% CI: 185, 636 ml). During daytime, Suprapubic catheters demonstrated higher UOP than urethral catheters per 12-hour shift (Estimated Difference: 464 ml; p=0.002; 95% CI: 211, 718 ml). During nighttime, a similar phenomenon was observed (Estimated Difference: 356 ml; p=0.009; 95% CI: 104, 606 ml). When comparing mean UOP from each catheter during the Bedrest Phase, suprapubic catheters averaged an estimated 295 ml higher UOP compared to urethral catheters per 12-hour shift with a trend toward statistical significance (p=0.052; 95% CI -3, 594 ml). During the Ambulatory Phase, mean suprapubic catheter UOP was an estimated 472 ml higher than urethral catheters per 12-hour shift (p=0.009; 95% CI 142, 802 ml). Conclusions: Simultaneous bladder drainage with urethral and suprapubic catheters shows greater drainage from the suprapubic catheter (35% vs 65%). When using two catheters, both can be placed to gravity to maximize bladder drainage as the suprapubic catheter can drain residual urine not adequately drained by the urethral catheter.

RESUMO

OBJECTIVES: To better define urethral catheter balloon pressures and extraction forces during traumatic placement and removal of urethral catheters. To help guide design for safer urethral catheters. MATERIALS AND METHODS: Measurements of balloon pressure were made upon filling within the urethra vs the bladder. Extraction forces were measured upon removal of a catheter with a filled balloon from the bladder. Models for the bladder and urethra included an ex vivo model (funnel, 'bladder', attached to a 30 F tube, 'urethra') and fresh human male cadavers. The mean (SEM) balloon pressures and extraction forces were calculated. RESULTS: In the ex vivo model, the mean (SEM) pressures upon filling the balloon with 10 mL were on average three-times higher within the ex vivo'urethra' (177 [6] kPa) vs 'bladder' (59 [2] kPa) across multiple catheter types. In the human cadaver, the mean balloon pressure was 1.9-times higher within the urethra (139 [11] kPa) vs bladder (68 [4] kPa). Balloon pressure increased non-linearly during intraurethral filling of both models, resulting in either balloon rupture (silicone catheters) or 'ballooning' of the neck of the balloon filling port (latex catheters). Removal of a filled balloon per the ex vivo model 'urethra' and cadaveric urethra, similarly required increasing force with greater balloon fill volumes (e.g. 9.34 [0.44] N for 5 mL vs 41.37 [8.01] N for 10 mL balloon volume). CONCLUSIONS: Iatrogenic complications from improper urethral catheter use is common. Catheter balloon pressures and manual extraction forces associated with urethral injury are significantly greater than those found with normal use. The differences in pressure and force may be incorporated into a safer urethral catheter design, which may significantly reduce iatrogenic urethral injury associated with catheterization.

RESUMO

Most free-flap phalloplasty reports describe the femoral artery and great saphenous vein as recipient vessels, with the deep inferior epigastric artery and venae comitantes (DIEA/V) only rarely reported. We review our experience with preferentially using the DIEA/V as recipient vessels in gender-affirming free-flap phalloplasty, with DIEV as primary venous outflow. Methods: We retrospectively reviewed consecutive patients who underwent gender-affirming free-flap phalloplasty at our single institution from June 2017 through June 2021. The DIEA/V was used as recipient vessels, with the DIEA/V pedicle externalized via a passageway made through the external inguinal ring. Results: Thirty-eight consecutive free flaps (26 radial forearm free-flap phalloplasties, 10 anterolateral thigh phalloplasties, and two radial forearm free-flap urethroplasties) were performed. Mean age was 37.3 years; mean BMI was 25.7. Mean follow-up was 17.9 months. All flaps were anastomosed to the DIEA/V, without use of vein grafts. Most flaps (89.5%) had at least two veins anastomosed. To augment outflow, a saphenous vein branch was used in one of 38 (2.6%) cases and other superficial veins were used in two of 38 (5.3%) cases. One of 38 (2.6%) cases (early in our experience) resulted in total flap loss. Conclusions: Advantages of the DIEA/V as free-flap phalloplasty recipient vessels include a short, direct pathway for vessels, excellent donor-recipient vessel size match that allows end-to-end anastomoses, and elimination of risks associated with arterialized interposed veins. When venous outflow appears compromised, we recommend a low threshold to use additional local or saphenous veins, though this is rarely needed given the DIEV's reliability.
