A systematic review and meta-analysis of urethral complications and outcomes in transgender men

Patient-reported outcomes after one-stage neourethral reconstruction in transmen with phalloplasty-associated strictures and fistulas

INTRODUCTION

Urethral strictures and fistulas arising after gender-affirming surgery in transmen require meticulous management strategies. This study evaluates the safety and efficacy of urethral reconstruction and patient satisfaction post-surgery.

METHODS

A retrospective analysis examined peri- and postoperative data from transmen undergoing urethral reconstruction for urethral fistula and/or strictures at the distal urethral anastomosis between December 2017 and April 2023. Follow-up involved clinical examinations, uroflowmetry, and voiding cystourethrography. Patient satisfaction and quality of life were assessed using USS PROM and ICIQ-S questionnaires.

RESULTS

Among 25 patients, 88% (n = 23) had urethral fistulas, and 48% (n = 12) had urethral strictures. 41% of fistula patients also had strictures, while 75% of stricture patients had concurrent fistulas. Previous surgeries for fistula or stricture repair were noted in 26% of cases. Techniques for stricture included modified flap (50%), buccal oral mucosal grafting (33%), and primary anastomosis (17%). Post-operative urethrogram revealed urethral strictures in 15% (n = 3) and urinary extravasation in an equal number. Postoperative uroflow parameters showed improvement (Qmax 18 ml/s, Qave 7.9 ml, time 37 s, volume 332 ml). Perioperative complications were low (n = 6, 24%), all grade one (Clavien-Dindo). Follow-up revealed that 33% required another surgical intervention. The mean six-item LUTS score was 6.7 (SD 3.9). Mean ICIQ-S overall satisfaction score was 8.6 (SD 1.6) and outcome score was 20 (SD 2.8).

DISCUSSION

Our study found a significant recurrence rate of urethral strictures and fistulas post-surgery. Despite this, patient satisfaction remains high and complications are generally low-grade, highlighting the importance of expert surgical intervention.

Validation of Lower Urinary Tract Symptom Questionnaire in the Transmasculine Population

INTRODUCTION AND HYPOTHESIS

Transgender men and transmasculine individuals report a variety of lower urinary tract symptoms (LUTS), but little is known about LUTS in this population. One of the obstacles is the lack of validated questionnaires. This study was aimed at validating the International Consultation on Incontinence Questionnaire-Lower Urinary Tract Symptoms (ICIQ-LUTS), which measures filling, voiding, and incontinence symptoms, in transmasculine individuals.

METHODS

This is an observational validation study that included transmasculine individuals receiving care within a single tertiary care hospital system. Construct validity was assessed by comparing the ICIQ-LUTS with severity of LUTS as measured by the Urinary Distress Inventory-Short Form (UDI-6), and concurrent validity by the association between ICIQ-LUTS and the Patient Perception of Bladder Condition (PPBC). Discriminant validity was determined by comparing ICIQ-LUTS scores in those with and those without self-reported LUTS. Spearman correlation, t test, and Kruskal-Wallis test were used for data analysis.

RESULTS

A total of 131 respondents were included in the analysis. Only two individuals (1.5%) reported prior vaginectomy and/or phalloplasty. Concurrent validity was demonstrated by a significant association between ICIQ-LUTS subscales and PPBC (filling p < 0.001, voiding p < 0.001, incontinence p < 0.001). Construct validity was demonstrated by a significant correlation between ICIQ-LUTS and UDI-6 (filling ρ = 0.76, p < 0.001; voiding ρ = 0.48, p < 0.001; incontinence ρ = 0.61, p < 0.001). For discriminant validity, those with at least one self-reported LUTS had significantly higher (worse) ICIQ-LUTS subscale scores than those without self-reported LUTS.

CONCLUSIONS

The ICIQ-LUTS is valid for measurement of LUTS severity in transmasculine individuals. This will be an important tool to use in future research to learn more about LUTS in this population.

Urethral Outcomes of the Labia Minora Ring Flap for Metoidioplasty and Phalloplasty

OBJECTIVE

To determine urethral outcomes of single-stage metoidioplasty and radial forearm free flap (RFFF) phalloplasty using the labia minora ring flap for urethral lengthening (UL).

METHODS

A retrospective review was performed of patients undergoing single-stage metoidioplasty and RFFF phalloplasty utilizing the labia minora ring flap technique. The ring flap consists of endodermal labia minora tissue ventral to the clitoris and surrounding the vaginal introitus. During metoidioplasty, the ring flap accounts for the entirety of UL. During RFFF phalloplasty, the ring flap becomes the pars fixa (PF) urethra. The primary outcomes measured were rates of fistula, stricture, and surgical revision.

RESULTS

Between November 2017 and August 2023, 311 patients underwent metoidioplasty or RFFF phalloplasty (mean follow-up 37 months). Of the 69 metoidioplasties, urethrocutaneous fistulas developed in 11 patients (16%); strictures occurred in 4 (6%). Of the 242 phalloplasty patients, there were 71 fistulas (29%), 56 of which resolved spontaneously. Strictures developed in 44 patients (18%). Twenty-five patients (10%) developed both a stricture and fistula. Surgical repair was required in 8/69 (12%) metoidioplasty patients and in 46/242 (19%) RFFF phalloplasty patients for an overall revision rate of 17%.

CONCLUSION

UL during metoidioplasty or RFFF phalloplasty can be accomplished in a single stage using the labia minora ring flap with comparable surgical revision rates to previously described techniques. This approach can also be applied to other phalloplasty techniques. Many fistulas of the PF urethra resolve spontaneously. Higher urethral revision rates were seen in phalloplasty compared to metoidioplasty.

Incidence, Complications, and Long-term Outcomes of Gender-affirming Phalloplasty: Analysis of a Large Statewide Population-based Dataset

OBJECTIVE

To evaluate the incidence of gender-affirming phalloplasty and postoperative complications in a large population-based dataset.

METHODS

Retrospective cohort study was done using the California Department of Health Care Access and Information datasets which include patient-level data from all licensed hospitals, emergency departments, and ambulatory surgery facilities in California. Adult patients 18 years or older undergoing gender-affirming phalloplasty in California from January 1, 2009 to December 31, 2019 were included. We examined phalloplasty-related complications using International Classification of Disease diagnosis and procedure codes and Current Procedural Terminology codes. Unique record linkage number identifiers were used to follow patients longitudinally. Statistical analysis included Kaplan-Meier survival analysis and Cox proportional hazards analysis.

RESULTS

We identified 766 patients who underwent gender-affirming phalloplasty in 23 facilities. Of 475 patients with record linkage numbers, 253 (55.3%) had subsequent re-presentations to the inpatient, emergency department, and ambulatory surgery settings related to phalloplasty complications. Survival analysis indicated that 50% of patients re-presented by 1year post-phalloplasty. Asian/Pacific Islander patients had lower risk of complications, and California residents had higher risk of complications.

CONCLUSION

This population-based study confirms that gender-affirming phalloplasty has a high complication rate, and demonstrates for the first time an association with high rates of return to hospitals, emergency departments, and ambulatory surgery centers. These findings provide additional higher-level evidence that may aid patient counseling, shared surgical decision-making, and institutional and government policy.

[Choice of flaps for phalloplasty: what is the contemporary standard? Consensus Statement of the German-Speaking Society for Microsurgery of Peripheral Nerves and Vessels]

The ever-expanding number of transmen as well as their surgeons share an increasing interest in the construction of a neophallus. While the indication for surgery and the positive effect of a phalloplasty on the quality of life, mental health and sexual function has already been thoroughly analysed, there is a lack of data comparing and evaluating the surgical steps. During the consensus conference on the "choice of flaps for phalloplasty" at the annual meeting of the German-Speaking Society for Microsurgery of Peripheral Nerves and Vessels, the current literature was discussed and a consensus on the surgical technique of a phalloplasty was reached. This manuscript publishes jointly developed recommendations on the following topics: choice of flaps for phalloplasty, preoperative diagnostic tests before phalloplasty, urethral construction in the radial forearm flap and anterior lateral thigh flap, preformation of the urethra at the forearm or thigh, venous drainage of the radial forearm flap, innervation of the phallus, staged phalloplasty, coronaplasty and managing the donor site of a radial forearm flap.

A multimetric health literacy analysis of online gender affirmation surgery materials: From facial to genital surgery

BACKGROUND

The transgender patient population is expanding, and gender affirming surgery (GAS) volume is increasing. Accurate, comprehensive, and easily navigable resources on GAS are lacking. We aim to evaluate the readability of online materials for specific gender affirming surgical procedures to identify mechanisms of improving information access for transgender patients.

MATERIALS AND METHODS

"Facial feminization", "facial masculinization", "MTF breast augmentation", "FTM chest masculinization", "MTF vaginoplasty", "metoidioplasty", and "FTM phalloplasty" were searched on Google. Per keyword, the first 75 text-containing results were included. Text was analyzed for reading difficulty using the Flesch-Kincaid Reading-Ease (FKRE) test and grade level using the Flesch-Kincaid Grade Level (FKGL) formula, Gunning Fog Index (GFI), Simple Measure of Gobbledygook (SMOG), and Coleman-Liau Index (CLI). Scores were compared using independent t-and ANOVA tests (α = 0.05).

RESULTS

Mean readability scores (FKRE 37.44) and grade-levels (FKGL 12.87, GFI 15.61, SMOG 11.91, CLI 15.00) correlated with college-level difficulty. Masculinizing surgical materials were more difficult to read than feminizing ones (p ≤ 0.023). Top surgery materials were easier to read than facial and genital surgery materials (p ≤ 0.013). Specifically, chest masculinization resources were more difficult to read than those for breast augmentation (p ≤ 0.006). No differences were found between facial feminization and masculinization surgery resources, nor between resources for different gender affirming genital surgeries.

CONCLUSION

Online GAS materials are written above the recommended 6th grade reading-level, with resources for transgender men being significantly more challenging to understand. Improving readability of online resources can help overcome barriers to care for the transgender patient population.

[Genital gender affirming surgery in trans men]

OBJECTIVE

Genital surgery for masculinisation in the context of gender incongruence is characterised by the reconstruction of male genitalia using multiple surgical techniques - free flap phalloplasty, pedicled flap phalloplasty or metaoidioplasty - which this article aims to describe.

MATERIAL AND METHODS

A narrative review of the literature on these trans surgeries was carried out.

RESULTS

Each technique has specific advantages and disadvantages, and does not produce the same results in terms of surgical risks, size of the reconstructed phallus, sensitivity, sexual function and urinary function.

CONCLUSION

This surgical decision must therefore be shared with the person concerned, based on a clear understanding of their expectations and objectives. Long-term follow-up is recommended.

Functional and surgical outcomes after phalloplasty in cis men

PURPOSE

Evaluate the surgical outcomes along with a comprehensive assessment of functional outcomes in cis men (non-trans) who underwent phalloplasty.

METHODS

All consecutive cis men who underwent phalloplasty from 2008 to 2018 for penile insufficiency due to various causes were included. These underwent phalloplasty by either a radial forearm free flap (RFFF) or suprapubic phalloplasty (SPP). Data were collected from medical files. A questionnaire was sent a minimum of 1 year after surgery to each patient to evaluate sexual function and self-esteem, satisfaction with genitals, and urinary function.

RESULTS

Among the 19 patients included, 12 underwent RFFF and 7 SPP; 25% of those who had RFF and 14.3% of those with SPP had a Clavien-Dindo ≥ 2 complication. A total of 16 patients had a urethroplasty procedure, 50.0% of whom had a Clavien-Dindo ≥ 2 complication. Penile prostheses were implanted in 14 patients; 64.3% of whom had a complication. Seven patients answered the questionnaire (36.8%); the relationship satisfaction score was 89.5/100 and the confidence score was 100/100. Among the 5 patients who had a sexual relationship, all reported having a lot of pleasure during sexual intercourse and reached orgasm at least "regularly". At least 66.7% of the patients were "satisfied" or "very satisfied" about the size and the appearance of genitals. Among the 5 patients who answered questions regarding urinary function, 60.0% had standing micturition, and 80.0% reported being comfortable in public toilets.

CONCLUSION

Despite the high frequency of complications and the need for revision surgery, phalloplasty seems to allow a satisfying psychosexual and urinary functions for cis men suffering from penile insufficiency.
