Bourillon, Alice; Freton, Lucas; Verhoest, Gregory; Hascoet, Juliette; Richard, Claire; Haudebert, Camille; Mathieu, Romain; Zhao, Lee C; Bensalah, Karim; Peyronnet, Benoit
OBJECTIVES/UNASSIGNED:To compare the outcomes of open versus robotic ureteral reimplantation procedures at a single centre. MATERIAL AND METHODS/UNASSIGNED:The charts of all patients with ureteral strictures who underwent open ureteral reimplantation between 2005 and 2024, and those who underwent robotic reimplantation between 2013 and 2024, were retrospectively reviewed, and the outcomes of the two approaches were compared. RESULTS/UNASSIGNED:Eighty patients were included in the final analysis: 45 in the open surgery group and 35 in the robotic group. After a median follow-up duration of 16,5 months for the open group and 10 months for the robotic group, the stricture recurrence rate was similar in both groups (6,8% vs. 8.6%; p = 0.99). In terms of long-term complications, there were similar rates of symptomatic reflux (4.4% vs. 5.7%; p = 0.99) and flank pain (8.9% vs. 8.6%; p = 0.99) between both groups. There were more recurrent urinary tract infections in the open group (17.8% vs. 8.6%) and more de novo lower urinary tract symptoms in the robotic group (11.4% vs. 2.2%), but these differences were not statistically significant (p = 0.33 and p = 0.16, respectively). Overall, 30 patients (38%) had at least one long-term complication (35.6% vs 40%; p = 0.82). The only variable significantly associated with the risk of stricture recurrence was radiotherapy (OR = 11.2; p = 0.01). CONCLUSION/UNASSIGNED:The robotic approach appears to be non-inferior to the open approach in terms of stricture recurrence while being associated with a shorter length of hospital stay and lower estimated blood loss. More importantly, the present series raises questions regarding the long-term consequences of ureteral reimplantation and confirms the higher risk of failure in radiated patients.

Robotic ureteral reconstruction for endometriosis-induced strictures: insights from a multi-institutional experience
Lee, Matthew; Saxena, Sonam; Zhao, Kelley; Dodd, Cameron; Lee, Randall; Stifelman, Michael; Zhao, Lee; Eun, Daniel D
PURPOSE/OBJECTIVE:To investigate outcomes of robotic ureteral reconstruction (RUR) in female patients with ureteral strictures caused by peri-ureteral endometriosis lesions. METHODS:We retrospectively reviewed our multi-institutional Collaborative of Reconstructive Robotic Ureteral Surgery (CORRUS) database to identify all consecutive patients undergoing RUR for surgical management of endometriosis-induced ureteral strictures between 2017 and 2022. Indications for surgery included female patients with radiographic evidence of ureteral strictures and/or decreasing renal function on renal scan. We performed a descriptives analysis of perioperative outcomes in patients who met inclusion criteria. Surgical success was defined as freedom from additional interventions for recurrent ureteral stenosis. RESULTS:Overall, 19 patients met the inclusion criteria. Median age was 39 (IQR 30-43) years. Ureteral strictures were located in the middle ureter in 4 (21.1%) patients and in the distal ureter in 15 (78.9%) patients. Fourteen (73.6%) patients had a known preoperative diagnosis of endometriosis. RUR techniques included refluxing reimplantation (47.4%), side-to-side reimplantation (21.1%), ureteroureterostomy (21.1%), and buccal mucosa graft ureteroplasty (10.5%). There was one (5.3%) major postoperative complication (Clavien > 2) in which a patient developed an intrabdominal abscess requiring drainage by interventional radiology. Five (26.3%) patients were ultimately diagnosed postoperatively with endometriosis based on surgical pathology. At a median follow-up of 22.5 (IQR 11.7-41.5) months, 18 (94.7%) patients were surgically successful. CONCLUSION/CONCLUSIONS:Clinicians should maintain a high index of suspicion for endometriosis in premenopausal women with ureteral stricture disease. RUR techniques may be effective for the management of patients with ureteral strictures secondary to endometriosis.

Vaginoplasty Complications and Revisions
Parker, Augustus; Blasdel, Gaines; Bluebond-Langner, Rachel; Zhao, Lee
Choice of vaginoplasty technique is guided by the patient's natal anatomy, patient goals, and surgeon preference. The biggest distinction among techniques is the choice of lining for the vaginal canal. This chapter provides an overview of current data on the most pertinent complications, both universal and specific to different techniques for gender-affirming vaginoplasty. Clinical pearls for the management of these complications and indications for revision will be reviewed.

Robotic upper urinary tract reconstruction for ureteral stricture: a single-center series
Bourillon, Alice; Freton, Lucas; Hascoet, Juliette; Richard, Claire; Haudebert, Camille; Verhoest, Gregory; Mathieu, Romain; Zhao, Lee C; Bensalah, Karim; Peyronnet, Benoit
The surgical approach of ureteral stricture has changed dramatically over the past 15 years with the rise of robotic upper urinary tract reconstruction. This study aimed to evaluate the outcomes of all robotic ureteral reconstructions performed at a single academic center for ureteral stricture and to assess the predictive factors of stricture recurrence. The charts of all patients who underwent robot-assisted ureteral reconstruction between 2013 and 2024 at a single academic center were retrospectively reviewed. Many different surgical techniques were used including non-refluxing reimplantation with or without psoas hitch, refluxing ureteral reimplantation (side-to-side), Boari flap, uretero-ureterostomy, ureterolysis and buccal mucosa graft (BMG) ureteroplasty. The primary outcome was the absence of stricture recurrence, defined as no need for repeat surgery, urinary drainage, or symptomatic upper urinary tract dilation at the last follow-up. Sixty patients, accounting for 63 ureteral reconstructions, were included in the final analysis. Twenty-five patients experienced early postoperative complications (40%), the majority being Clavien-Dindo grade 2. There were only three (5%) major complications (Clavien-Dindo grade 3b). Stricture recurrence occurred in six patients (10%), with a median time to recurrence of 2.5 months postoperatively. Radiotherapy was the only factor significantly associated with an increased risk of stricture recurrence. The present series confirm the overall low morbidity and low recurrence rate of robotic ureteral reconstruction using a variety of surgical techniques. Comparative studies with longer follow-up periods are necessary to evaluate outcomes in comparison to traditional surgical approaches.

Exploring the Incidence of Testicular Neoplasms in the Transgender Population: A Case Series
Shanker, Elayna M; Ren, Qinghu; Zhao, Lee C; Bluebond-Langner, Rachel; Deng, Fang-Ming
CONTEXT.—/UNASSIGNED:The use of hormonal therapy and gender-affirming surgery in the transgender community has been rising during the last several years. Although it is generally safe, hormonal therapy's link to testicular cancer remains uncertain. OBJECTIVE.—/UNASSIGNED:To review the incidence of testicular cancer in specimens from gender-affirming orchiectomies at our institution and evaluate the tumors for histologic and genetic alterations. DESIGN.—/UNASSIGNED:Pathology reports for gender-affirming orchiectomies (January 1, 2018, to August 1, 2023) were reviewed for testicular neoplasms, with additional analysis for chromosome 12 abnormalities. Incidence and chromosome variations were compared with those in the general population. RESULTS.—/UNASSIGNED:Among 458 cases during 5.5 years, 5 germ cell neoplasms in 4 patients emerged. Our institution's annual incidence rate (159 per 100 000) is 26.5 times higher than the National Cancer Institute's previous report (6.0 per 100 000). Although they were morphologically no different from germ cell neoplasms in the general population, fluorescence in situ hybridization tests showed no i(12p) in 4 of 5 neoplasms (80%) in our cohort. CONCLUSIONS.—/UNASSIGNED:The cause behind this rise in incidence remains uncertain but may be due to long term pretreatment with hormones or blockers. The lower isochromosome 12p frequency suggests an alternative mechanism driving tumor development, which requires more detailed molecular studies.

Bridging the evidence gap in gender-affirming care: urgent research needs
Dolendo, Isabella; Zhao, Lee; Bluebond-Langner, Rachel; Anger, Jennifer T
Gender-affirming care has emerged as a critical component of healthcare, addressing the specific medical and psychosocial needs of transgender and non-binary individuals. In this review article, we address what we see as the most pressing evidence gaps in the gender health literature: long-term effects of pubertal blockers and gender-affirming hormone therapy and the lack of standardised outcome measures of gender-affirming care. Substantial uncertainties persist regarding long-term effects of hormone therapy and the implications of gender-affirming therapy on cancer risk. Though there is some uncertainty about the long-term effects of gender-affirming medical therapy, providers must also consider the potential negative consequences of prolonging a dysphoric experience. Additionally, there is a dearth of validated measures for patient-reported outcomes and a lack of standardisation in the reporting of data that is detrimental to the progress of understanding the impacts of gender-affirming care.

Patient-reported symptoms suggestive of vesicoureteral reflux after robotic ureteral reimplantation in adults
Chao, Brian W; Zhao, Kelley; Lee, Matthew; Lin, Jeffery S; Raver, Michael; Stifelman, Michael D; Zhao, Lee C; Eun, Daniel D
Little is known regarding the incidence of symptomatic, de novo vesicoureteral reflux (VUR) after ureteral reimplantation in adults. We sought to characterize this phenomenon in a contemporary cohort. We conducted a retrospective review of a multi-institutional database of robotic ureteral reconstruction (CORRUS, or Collaborative of Reconstructive Robotic Ureteral Surgery). Inclusion criteria were adult patients undergoing robotic ureteral reimplantation with at least 6 months of follow-up. Patients who had no evidence of recurrent ureteral stenosis were asked to complete a questionnaire characterizing their symptoms. The primary outcome was symptoms suggestive of VUR (SS-VUR), defined as flank pain of at least moderate severity that occurred at least weekly and worsened with voiding or a full bladder. We identified 257 patients who underwent robotic reimplantation, of which 97 (37.7%) were free from recurrent ureteral stenosis and responded to the questionnaire. At a median follow-up duration of 35.0 months (IQR 22.0-59.0), 26 patients (27.4%) reported flank pain of any severity on the same side as reimplantation. Nine patients (9.5%) met criteria for SS-VUR. Four patients underwent additional surgical intervention (two endoscopic, two robotic) after radiographic and functional workup confirmed VUR. On multivariable logistic regression, younger age was an independent predictor of SS-VUR (p = 0.041). In our contemporary series of robotic ureteral reimplantation in adults, over one-quarter of patients reported flank pain postoperatively in the absence of ureteral obstruction. A small proportion of patients had more bothersome symptoms particularly suggestive of VUR.

IMPORTANCE/UNASSIGNED:There is an urgent need for a validated gender-affirming care-specific patient-reported outcome measure (PROM). OBJECTIVE/UNASSIGNED:To field test the GENDER-Q, a new PROM for gender-affirming care, in a large, international sample of transgender and gender diverse (TGD) adults and evaluate its psychometric properties. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This international cross-sectional study was conducted among TGD adults aged 18 years and older who were seeking or had received gender-affirming care within the past 5 years at 21 clinical sites across Canada, the United States, the Netherlands, and Spain; participants were also recruited through community groups (eg, crowdsourcing platform, social media). The study was conducted between February 2022 and March 2024. Participants had to be capable of completing the instrument in English, Danish, Dutch, or French-Canadian. Eligible participants accessed an online REDCap survey to complete sociodemographic questions and questions about gender-affirming care they had received or sought (ie, to look, function, or feel masculine, feminine, gender fluid, or another way). MAIN OUTCOME AND MEASURES/UNASSIGNED:Branching logic was used to assign relevant instrument scales. Rasch measurement theory (RMT) analysis was used to examine the fit of the observed data to the Rasch model for each scale. Test-retest reliability and hypothesis-based construct validity of instrument scales were examined. The hypothesis was that instrument scale scores would increase with better outcomes on corresponding categorical questions. RESULTS/UNASSIGNED:A total of 5497 participants (mean [SD] age, 32.8 [12.3] years; 1837 [33.4%] men; 1307 [23.8%] nonbinary individuals; and 2036 [37.0%] women) completed the field test survey. Participants sought or had the following types of gender-affirming care: 2674 (48.6%) masculinizing, 2271 (41.3%) femininizing, and 552 (10.0%) other. RMT analysis led to the development of 54 unidimensional scales and 2 checklists covering domains of health-related quality of life, sexual, urination, gender practices, voice, hair, face and neck, body, breasts, genital feminization, chest, genital masculinization, and experience of care. Test-retest reliability of the scales (intraclass correlation coefficient [average] >0.70) was demonstrated. Only 1 item (phalloplasty donor flap) had an ICC less than 0.70. As hypothesized, scores increased incrementally with better associated self-reported categorical responses. For example, among 661 participants who reported poor psychological well-being, the mean (SD) scale score was 45 (18) points; for those who reported excellent psychological well-being, the mean (SD) scale score was 85 (16) points (P < .001). CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this cross-sectional study of 5497 TGD adults, the instrument demonstrated reliability and validity. The instrument was validated in an international sample and is designed to collect and compare evidence-based outcome data for gender-affirming care from the patients' perspective.

Quantifying the Learning Curve in Robotic Peritoneal Flap Vaginoplasty
Hemal, Kshipra; Blasdel, Gaines; Parker, Augustus; Amro, Chris; Dubach-Reinhold, Charlie; Zhao, Lee C; Bluebond-Langner, Rachel
BACKGROUND:The learning curve (LC) is the process of mastering a new technique. This study assesses the LC for robotic-assisted peritoneal flap gender-affirming vaginoplasty (RPGAV). METHODS:A retrospective chart review of all consecutive patients undergoing RPGAV between 09/2017 and 02/2023 at a single center was performed. Operative times (OT) were analyzed to describe the LC. A cutoff point was determined after which OT stabilized, and this was used to compare perioperative and postoperative outcomes. RESULTS:Five hundred RPGAVs were performed. Median OT was 125 (interquartile range 105-181) minutes and decreased significantly over time. The minimum number of cases required to observe a plateau in OT is 300 patients.After adjusting for the LC, 2 variables significantly affected OT: a 1-point increase in body mass index increased OT by 1.4 minutes [95% confidence interval (1.0, 1.9), P < 0.001] and the single port robot decreased OT by 34 minutes [95% CI 1 (-43.1, -25.0), P < 0.001] as compared to the traditional multiport Xi robot.When comparing the first 300 cases (learning phase) to the last 200 (expert phase), length of stay, blood transfusions, and rates of elective revision surgery were lower in the expert phase. CONCLUSIONS:The LC for RPGAV in this large cohort was 300 cases. Patient body mass index causes a dose-response increase in OT and the single port robot dramatically decreases OT. Although OT is just one facet of overall efficiency, differences between learning and expert phases are evident in decreased length of stay, transfusions, and rates of revision surgery.

Patient-centered outcomes on preparing for and undergoing gender-affirming phalloplasty: a qualitative, descriptive study
Mmonu, Nnenaya; Radix, Asa; Castle, Elijah; Zhao, Lee; Bluebond-Langner, Rachel; Ospina-Norvell, Clarissa; Harel, Daphna; Fendrick, Mark; Zhang, Tenny R; Berry, Carolyn A
OBJECTIVE:Despite increasing incidence of genital gender-affirming surgery (GGAS), there is no systematic method of evaluating patient perspectives. The objective of this study is to elucidate transgender and non-binary patient perspectives on gender-affirming phalloplasty/metoidioplasty via structured focus groups and determine convergent themes as the first step towards the development of a GGAS patient-reported outcome measure. DESIGN/METHODS:We conducted a systematic qualitative study using a thematic content analysis of four focus groups from April 2021 to April 2022 comprising 8 patients undergoing phalloplasty/metoidioplasty and 10 patients post-phalloplasty/metoidioplasty. Focus groups were hosted virtually and recorded and transcribed. Discussions were guided by participant input and focused on goals, experiences, outcomes, satisfaction, and quality of life. SETTING/METHODS:This volunteer but purposive sample of patients was recruited directly in clinic, via email, and via social media at NYU Langone Health (primary site), Callen-Lorde Community Health Center (New York, New York, USA) and the San Francisco Community Health Center. PARTICIPANTS/METHODS:We conducted focus groups with 18 patients before/after undergoing gender-affirming phalloplasty/metoidioplasty. PRIMARY AND SECONDARY OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Transcripts were uploaded into ATLAS.ti, a qualitative data analysis software that facilitates coding for thematic content analysis. We performed deductive and inductive coding to identify the themes that were clustered into overarching domains. RESULTS:The mean duration of focus groups was 81.5 min. Seven themes and 19 subthemes were constructed. The major themes were (1) goals, expectations, and priorities before/after surgery; (2) sexual function; (3) urinary function; (4) peer support; (5) decision-making; (6) mental health and quality of life; and (7) gender dysphoria. Of the major themes, those determined before the study included themes 1-3 and 6-7. Limitations include small sample size and bias in patient selection. CONCLUSIONS:We conducted focus groups with 18 patients before/after undergoing gender-affirming phalloplasty/metoidioplasty. Mental health, quality of life, functional, and aesthetic outcomes are all critical to patients. Phalloplasty/metoidioplasty impact numerous aspects of patients' lives. Experiential components of the surgical process, mental health, and quality of life are important metrics to consider in addition to functional and aesthetic outcomes.
