Musculocutaneous latissimus dorsi flap for phalloplasty in female to male gender affirmation surgery

Penile prosthesis for erectile dysfunction: recommendations from the 5th International Consultation on Sexual Medicine

INTRODUCTION

Penile prosthesis (PP) is one of the main approved therapies for erectile dysfunction (ED). Greater than 50 years of clinical use has led to considerable innovation in PP surgery and patient care.

OBJECTIVES

To summarize the current literature and provide updated clinical evidence to inform healthcare providers on best practices with PP.

METHODS

A consensus panel was held with leading sexual medicine experts during the 5th International Consultation on Sexual Medicine (ICSM). Relevant peer-reviewed literature was reviewed with focus on research from but not limited to the last 10 years. The quality of each individual study was judged with Oxford levels of evidence (LOE) criteria, but overall LOE were not used as systematic review was not performed. The expert panel generated consensus statements based on the quality of evidence and criteria of GRADE (Grading of Recommendations Assessment, Development and Evaluation).

RESULTS

PP provides excellent outcomes for the treatment of ED. The panel developed 35 recommendations building upon previous recommendations. Nine recommendations (4, 5, 11,13,17, 25, 26, 31, and 32) are retained without change from 2015. Twelve recommendations (1, 2, 3, 7, 9,14,16,19,21, 28, 33, and 34) change syntax to make statements more active or change details. Fourteen recommendations (6, 8, 10, 12, 15, 18, 20, 22, 23, 24, 27, 29, 30, and 35) are novel in this update.

CONCLUSION

Since the 4th ICSM, new evidence has emerged to guide PP use in modern sexual medicine. While multi-institutional studies are needed to improve outcomes, key challenges remain: reducing infections, enhancing devices, and improving awareness and accessibility. We recommend following 5th ICSM guidelines while emphasizing the importance of clinical judgment and shared decision-making for optimal PP outcomes.

Redo phalloplasty and/or urethraplasty after previous flap failure in phalloplasty in transgender men: surgical considerations and outcomes

BACKGROUND

Primary phalloplasty in transgender men can be performed using a single or double free or pedicled flap to reconstruct the shaft and, if desired, the urethra. Vascular complications may result in total or partial loss of the used flap(s). Surgical management after flap loss in primary phalloplasty presents a challenge to the reconstructive surgeon.

AIM

To describe our experience with surgical reconstructive management after primary phalloplasty flap loss in transgender men and report on the clinical and participant-reported outcomes.

METHODS

All transgender men who underwent a secondary reconstructive procedure after failure of the primary procedure between January 1989 and December 2023, at our institution, were identified. A retrospective chart review was conducted, recording relevant demographic and clinical data. In addition, participants were invited to complete a non-validated questionnaire consisting of questions regarding surgical outcomes, (sexual) functionality, and sexuality.

OUTCOMES

Surgical outcomes, flap failure, and self-reported outcomes.

RESULTS

Eighteen individuals were included in this study, who underwent flap reconstruction of the phalloplasty shaft (n = 7), the urethra (n = 4), or both (n = 7). Primary phalloplasty was performed with urethral lengthening (UL) in 16 (89%) and without in 2 (11%). There were no redo phalloplasty flap failures. In those with UL 13/16 (81%) were able to void while standing. Eleven individuals completed the follow-up questionnaire. Most participants were "satisfied" (45%) or "very satisfied" (27%) with the appearance of their penis. All participants (strongly) agreed that when looking back, they would undergo the surgery all over again.

CLINICAL IMPLICATIONS

Practical surgical tips, deducted from our experiences, are provided for gender surgeons performing (revision) phalloplasty and urethroplasty.

STRENGTHS AND LIMITATIONS

Strengths are the unique set of surgical reconstruction cases that has taught us valuable lessons. Data from this study can be used to optimize pre-operative counseling regarding flap loss complications and the outcomes of the subsequent management. Weaknesses comprise the retrospective nature, the low number of included individuals, and use of non-validated questionnaires for self-reported outcomes.

CONCLUSION

Flap loss after primary phalloplasty in transgender men is a serious complication. Successful secondary reconstruction of the phalloplasty can be performed using a new pedicled or free flap.

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.

Musculocutaneous Latissimus Dorsi Phalloplasty: Technique and Tips

BACKGROUND

Musculocutaneous latissimus dorsi (MLD) phalloplasty is a gender-affirming surgical option for transmen which permits penile prosthesis, glansplasty, and urethral extension at later stages. This surgery allows for a neophallus of adequate length and girth, and minimal donor site morbidity, but is technically complex.

OBJECTIVE

This video demonstrates a step-by-step technique and tips to optimize outcomes and simplify the operation for the MLD phalloplasty.

MATERIALS AND METHODS

A 33-year-old transmale who previously underwent metoidioplasty presented for an MLD phalloplasty. With the patient in a supine position, the superficial femoral artery and saphenous vein are isolated at the recipient site. The patient is repositioned into a lateral flank position, the flap harvested and tubularized, and inferior aspects of the wound closed prior to harvesting the thoracodorsal artery (TDA) and thoracodorsal vein (TDV) to minimize cold ischemia time. The TDA and TDV are dissected to their root at the subscapular artery and vein. The artery is removed with a patch of the subscapular artery. The patient is initially in a supine position and then returned to a supine position to minimize ischemia time of the flap. The neophallus is attached to the previously created recipient site, and an end-to-side anastomosis is created between the superficial femoral artery and TDA and an end-to-end anastomosis between the saphenous vein and the TDV. If the patient has a thick latissimus dorsi muscle or subcutaneous fat, a split-thickness skin graft can be used to close the ventral phallus to minimize tension on the tubularized neophallus and provide a plate for a future urethral lengthening procedure. Positioning and close post-op monitoring of the neophallus are critical.

RESULTS

A neophallus of adequate length and girth is created with the option for future urethral extension and penile prosthesis placement.

CONCLUSION

Our video demonstrates the technique for a gender-affirming MLD phalloplasty in a transman and tips to optimize outcomes and simplify the operation.

Phalloplasty With a Free Scapular Flap Improves Postoperative Sensation in Penile Reconstruction

Objective We aimed to evaluate both the long-term surgical outcomes and patient-reported outcomes of free scapular flap (FSF) phalloplasty. Method The same surgical team performed phalloplasty in 66 patients using a FSF between March 2000 and September 2018. All patients had at least 24 months of follow-up. The surgical techniques used, complications observed, and surgical and patient-reported outcomes were retrospectively described. Results A total of 66 patients with indications of penile trauma (n = 19), micropenis (n = 42), and self-amputation (n = 5) underwent FSF phalloplasty. Two patients (3%) had total flap necrosis and 1 (1.5%) had partial flap necrosis. The urethral complication rate was 18.2% (12/66 patients). All patients were able to void while standing after revision procedures or urethroplasty. We found that an FSF is a reliable donor site for penile reconstruction. Conclusion The FSF phalloplasty creates an esthetically pleasing penis and allows voiding while standing. Most patients can engage in sexual activity. The main drawbacks of using this method are that patients experience different degrees of sensory recovery, and patients undergoing surgery with the "tube-in-tube" technique may find they are be limited by the thickness of the flap. However, by making full use of residual tissue, such as the micropenis glans or scrotal skin, patients can obtain good tactile and erogenous sensation. We believe that using an FSF complements the existing phalloplasty techniques.

[The tube in tube thoracodorsal perforator flap phalloplasty]

This article deals with a clinical case of a tube in a tube TDAP phalloplasty in a 38 years old trans-man. While penis reconstruction surgery aroused an efflorescence of different operative techniques, the resulting female to male surgery sees these procedures boil down to two or three flaps. If we usually discuss before surgery about the way to lengthen the urinary tract, as the way to implant later for intercourse; the choice of the donor site remains too systematized. Surgeons commonly focus on the reconstructed site prior to the donor site. In this case, laxity in the back and reliability of direct closure make us harvest the thoracodorsal perforator flap. Dissection of perforators saves muscular function and direct closure afford an aesthetic result less visible than a graft on the forearm. The thin flap we harvest allows tube in tube phalloplasty so that phallus and urethra are being built in the same time. One case has been reported in the literature of thoracodorsal perforator flap phalloplasty with grafted urethra, but no case of tube within a tube TDAP phalloplasty.

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

PURPOSE

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

METHODS

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

RESULTS

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

CONCLUSION

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

30 Years of Experience in Musculocutaneous Latissimus Dorsi Flap Phalloplasty with Reinnervation: Optimal Principles

The technique of urogenital plastic surgery continues to pose difficulties for surgeons due to physical features of the anatomical region, which complicates the correction of various severe male urogenital pathologies. The goal of the surgeon is to create a neophallus that allows for urination and intercourse with minimal damage to the donor site. This special topic provides a historical overview and principles for optimal phalloplasty. To improve results in latissimus dorsi free-flap phalloplasty, we share our approach, its benefits, and the lessons we have learned.

Methods

We performed a retrospective review of patients who underwent shaft-only, two-stage or one-stage latissimus dorsi flap phalloplasty with or without reinnervation at a single institution from 1991 through 2020. Patients with a minimum of 1 year of follow-up were included. Data on the patient's demographics, the procedure, and the results of the operation were maintained.

Results

In total, 592 latissimus dorsi flap phalloplasties were performed during the entire study period. Of the phalloplasties, 494 (83.5%) were performed for gender-affirming surgery, of which 470 were performed for transgender patients and 24 for intersex patients. Twenty-five patients (4.2%) had congenital malformations, 17 (2.9%) had oncologic resections, and 56 had posttraumatic loss (9.5%).

Conclusion

Latissimus dorsi flap total phalloplasty with reinnervation is currently one of the few methods that can solve not only an aesthetic problem, but also a functional one without the use of an endoprosthesis if the level of reinnervation and muscle contraction is sufficient.

Surgical Outcomes at a Single Institution of Infrapubic Insertion of Malleable Penile Prosthesis in Transmen

OBJECTIVE

To describe our technique for the infrapubic approach for malleable penile prosthesis (MPP) insertion after phalloplasty in transgender men and review surgical outcomes.

METHODS

The infrapubic prosthesis insertion technique involves a horizontal incision anterior to the pubic symphysis, allowing dissection of the neophallus tract and anchor site on the pubic symphysis. Surgical outcomes by a single surgeon using a Spectra or Genesis MPP between October 2017 and May 2022 were retrospectively reviewed. Complications were categorized into erosions, infections, device detachment, device malposition, pain or activity limitation, urethral injury, and flap loss. Implant survival kinetics were assessed by evaluating time to surgical revision.

RESULTS

Forty patients underwent infrapubic MPP insertion; 35 patients had a prior radial forearm free flap (RFFF) and 5 had a prior anterolateral thigh flap (ALT) phalloplasty. Of 30 patients who maintained follow-up, mean follow-up was 34.9 months. Complications were not mutually exclusive, with 7 implant detachments from the anchor site, 3 malpositions, 2 with pain/activity limitation, and 1 infection. Surgical revision was required in 12/30 patients (40%). There were no neophallus erosions, flap loss, nor urethral injuries. More complications occurred with the Spectra (9/17 or 53%) than the Genesis MPP (3/13 or 23%), but this was not statistically significant (P = .10).

CONCLUSION

Infrapubic insertion in transmen after phalloplasty using commercially available MPPs is safe compared with other post-phalloplasty penile prosthesis insertion techniques, with similarly high surgical revision rates. Further study of techniques is needed to improve outcomes after penile prosthesis insertion in transmen.

Insertion of inflatable penile prosthesis in the neophallus of assigned female at birth individuals: a systematic review of surgical techniques, complications and outcomes

Devices such as inflatable penile prostheses (IPP) can be used to achieve erectile rigidity after phalloplasty in assigned female at birth (AFAB) individuals. The approach to inserting an IPP in a neophallus is different and more challenging compared to that of an anatomical penis due to the absence of anatomical structures such as the corpora cavernosa, and the more tenuous blood supply of the neophallus and reconstructed urethra. In addition, the ideal surgical techniques and devices for use in the neophallus have not been defined. This review systematically summarises the literature on the insertion of IPP in the neophallus of individuals AFAB. In particular, the described techniques, types of devices used and peri-operative and patient-reported outcomes are emphasised. An initial search of the PubMed database was performed on 16 September 2022 and an updated search was performed on 26 May 2023. Overall, 185 articles were screened for eligibility and 15 studies fulfilled the inclusion criteria and were included in the analysis. Two studies reported outcomes on the zephyr surgical implant 475 FTM device and the others reported outcomes on the Boston Scientific AMS 600/700TM CX 3-piece inflatable, AMS AmbicorTM 2-piece inflatable, Coloplast Titan® or Dynaflex devices. Overall, 1106 IPPs were analysed. The infection rate was 4.2%-50%, with most studies reporting an infection rate of <30%. Mechanical failure or dysfunction occurred in 1.4%-36.4%, explantation was required in 3.3%-41.6%, and implant revision or replacement was performed in 6%-70%. Overall, 51.4%-90.6% of patients were satisfied and 77%-100% were engaging in sexual intercourse. An IPP in a neophallus is an acceptable option to achieve rigidity for sexual intercourse. However, this challenging procedure has good reports of patient and partner satisfaction despite significant risks of complications.

Phalloplasty following penectomy for penile cancer

Objective

Penile reconstruction or phalloplasty following penectomy can be offered where the functional penile length is inadequate for a man to void while standing or to have sexual intercourse. Phalloplasty is usually staged due to the complex surgical techniques required. This narrative review describes the technical concepts and summarises the contemporary outcomes following phalloplasty in this challenging cohort.

Methods

A retrospective review of the English literature was performed between January 1946 till November 2021. The data were synthesised and complemented by the expert opinion of the authors with 20 years of experience in this field. The flaps are ideally designed with an integrated urethra or alternatively, a further free flap urethroplasty can be offered. Phalloplasty is further complicated following penectomy by scarring from the previous surgery and the potential loss of structures that would normally be present at the recipient site.

Results

There are limited published data with a total of 19 men recorded in the literature. Only the radial artery forearm free flap and anterolateral thigh flap have been described in this cohort of patients. Functional outcomes including standing micturition, sensation in the neophallus, and the ability to orgasm are good. Overall quality of life and satisfaction was also good despite the high risk for long-term complications of the neophallus and donor site.

Conclusion

Phalloplasty following penectomy requires microsurgical transfer of a free flap or a pedicled flap to reconstruct a neophallus. An erectile device is inserted at a later stage to facilitate sexual intercourse, if desired. Surgical scarring from penectomy and the potential loss of vasculature that would normally be present at the recipient site may further complicate reconstruction. Surgical and functional outcomes are acceptable based on the limited published experience to date.

Penile Prosthesis in Transgender Men after Phalloplasty

A penile prosthesis can be successfully implanted after phalloplasty in transgender men to permit sexual intercourse. A prosthesis can be categorized as malleable or inflatable. The most common penile prosthesis implanted after masculinizing genital surgery is the inflatable prosthesis but this can be a challenging operation with high complication rates. Penile prosthesis in transgender patients differs from cis-patients in many respects but one critical difference is the absence of the tough, protective tunica of the corporal body to contain the prosthesis. This causes greater mobility of the prosthesis under the skin and increases the risk of migration and erosion of the device through the skin. In addition, to overcome the absence of a corpora cavernosa, the proximal portion of the prosthesis must be anchored to bone. Complications include injury to the urethra, vascular injury, skin breakdown, infection, device migration, device failure, extrusion, and erosion. There is no robust data on the use of penile prosthesis in transgender men with only multiple reports of small numbers of patients. While successful implantation can improve patients' quality of life, surgeons should counsel patients about the relatively high risk of the need for revision surgery.

Musculocutaneous Latissimus Dorsi Phalloplasty

The treatment of gender dysphoria consists of psychiatric evaluation, initiation of hormonal therapy, and the final step in an individual's transition, performing gender-affirming surgery. Construction of the neophallus is one of the most demanding tasks in genital affirming surgery of transgender men. The main objectives of phalloplasty are to achieve a cosmetically acceptable and functional phallus, with a neourethra that allows voiding in standing position, sufficient length and strength for possible penetrative intercourse, preserved tactile and orgasmic sensation, and acceptable donor site morbidity. The musculocutaneous latissimus dorsi flap has reliable and suitable anatomy (good size, volume, and length of neurovascular pedicle) to meet the esthetic and functional requirements of neophallus reconstruction. Despite many advantages, the main disadvantage of this flap is the lack of sensitivity. Although the radial free forearm flap technique is the most commonly performed procedure, musculus latissimus dorsi flap is an acceptable choice in gender-affirming surgery.

Surgical satisfaction and quality of life outcomes reported by transgender men and women at least one year post gender-affirming surgery: A systematic literature review

Background

Many transgender women and men undergo gender-affirming surgeries. Existing work shows that early surgery outcomes are generally positive, suggesting high surgical satisfaction and positive quality of life outcomes. Less work, however, examines these outcomes in the longer-term.

Aims

To conduct a systematic literature review into the longer-term (i.e., ≥ 1 year) surgical satisfaction and quality of outcomes following various forms of gender-affirming surgery in transgender populations. Specifically, we aim to examine research on such outcomes at least one-year post gender-affirming chest, genital, facial, vocal cord, and Adam's apple removal surgeries.

Methods

Studies were identified through Google Scholar, PsycINFO, Scopus, and PubMed databases, as well as through Google Scholar search alerts. We considered all studies published until October 2021. Two reviewers extracted data from suitable studies using Covidence. Both reviewers also independently assessed the identified studies' risk of bias and strength of evidence.

Results

Seventy-nine low quality (e.g., small sample sizes, lack of control/comparison groups) studies suggest that most transgender patients are satisfied with surgical outcomes when assessed at least one-year post-surgery. Low quality research also indicates that transgender women and men typically report positive psychological and sexual wellbeing post-surgery, and similar wellbeing outcomes as those who have not had surgery.

Discussion

To the best of our knowledge, this literature review is the first to critically summarize and evaluate all published studies on the longer-term quality of life outcomes following chest, genital, facial, voice and Adam's apple removal surgeries for transgender women and men. While the results suggest promising surgical satisfaction and quality of life outcomes following surgery, many studies only draw on small samples, and most studies do not allow for causal conclusions. Further, few studies have compared surgical outcomes between transgender women and men. We conclude by offering concrete suggestions for future research.

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

BACKGROUND

Urologic problems, such as urethral fistulas and strictures, are among the most frequent complications occurring after phalloplasty. Although many studies have reported successful phalloplasty and urethral reconstruction with reliable outcomes in transgender men, no method has become standardized so far. This study aimed to summarize the results of reports on urological complications and outcomes in transgender men with respect to various types of urethral reconstruction.

METHODS

A comprehensive literature search of PubMed, Scopus, and Google Scholar databases was conducted for studies related to phalloplasty in transsexuals. Data on various phallic urethral techniques, urethral complications, and outcomes were collected and analyzed using the random-effects model.

RESULTS

A total of 21 studies (1,566 patients) were included: eight studies (1,061 patients) on "tube-in-tube," nine studies (273 patients) on "prelaminated flap," and six studies (221 patients) on "second flap." Compared with the tube-in-tube technique, the prelaminated flap was associated with a significantly higher urethral stricture/stenosis rate; however, there was no difference between the prelaminated flap and the second flap techniques. For all phalloplasty patients, the pool rate of urethral fistula or stenosis is 48.9%, the rate of the ability to void while standing is 91.5%, occurrence rate of tactile or erogenous sensation is 88%, the prosthesis complication rate is 27.9%, and patient-reported satisfactory outcome rate is 90.5%.

CONCLUSION

Urethral reconstruction with a prelaminated flap was associated with a significantly higher urethral stricture rate and increased need of revision surgery compared with that observed using a skin flap. Overall, most patients were able to void while standing and were satisfied with the outcomes.

[Scapular flap, an alternative to the radial forearm flap in phalloplasty: Advantages and limitations]

INTRODUCTION

Antebrachial phalloplasty is considered as the standard technique in total penile reconstruction. This technique allows the creation of a phallus and a neourethra in one step at the cost of significant sequelae of the donor site. Thus, this technique has been replaced in some centers by other techniques such as the MSLD flap or the ALT flap. However, in Western populations, these techniques require the addition of a technique dedicated to the urethroplasty. The scapular flap is a technique that is not widely described in the literature and, like the antebrachial flap, allows the creation of a phallus and a urethra in one step according to the "tube within tube" technique.

AIM

The aim of the study was to detail this technique, to study its vascularization and to adapt the measurements of the flap to a western population.

PATIENTS AND METHODS

Six cadaveric dissections were performed in the laboratory. Intravascular injection of colored latex allowed easier identification of the vessels of interest and study of the subcutaneous vascular tree. Scapular flaps of variable size were raised to adapt the size to a Western population.

RESULTS

Six dissections were performed in Caucasian subjects. The scapular circumflex artery was constant and had a mean diameter of 3.5mm (3.3mm-3.8mm). The mean pedicle length was 7.3cm (6.8cm-8.1cm). The size of the flaps was adapted to the subcutaneous tissue and flaps of at least 14×16cm allowed the "tube within tube" technique to be performed.

CONCLUSION

The scapular flap has the advantage of allowing phalloplasty with urethroplasty to be performed at the same time. The pedicle is constant and of good diameter. In addition, the sequelae of the donor site are minimal. On the other hand, the pedicle used is short and the flap cannot be surgically reinnervated. Nevertheless, the restoration of a protective sensitivity allows the implantation of a penile prosthesis.

Options for Masculinizing Genital Gender Affirming Surgery: A Critical Review of the Literature and Perspectives for Future Directions

INTRODUCTION

Masculinizing genital gender affirmation surgery (MgGAS) has witnessed significant change in recent years. With the increasing number of patients seeking out GAS, optimization of techniques is mandated.

OBJECTIVES

To critically review the evolution of MgGAS, in a manner that encompasses the history and scope of the procedures, including phalloplasty with and without urethral lengthening, metoidioplasty with and without urethral lengthening, penile prosthesis placement, scrotoplasty, testicular prosthesis placement, vaginectomy, and hysterectomy.

METHODS

A comprehensive literature review was conducted in accordance with PRISMA guidelines, using PubMed. For our search, we generated a comprehensive list of MgGAS, combined with synonyms for GAS to ensure that articles included transgender cohorts. We identified a total of 547 articles from the search terms. Of these articles, 144 abstracts were relevant. Among these abstracts, 108 manuscripts were reviewed in full of which 98 were acceptable for inclusion. We excluded non-English-language studies without translation and studies that did not describe primary gGAS (eg, revision surgeries).

RESULTS

The evolution of MgGAS encompasses mostly refinements of pre-existing procedures, rather than new techniques or "watershed" procedures. The literature is somewhat lacking in outcomes-reporting that identifies the specific anatomy and surgical technique(s) used during gGAS. Without clarity regarding anatomy and technique, it is not feasible to compare surgical outcomes.

CONCLUSION

There is no ideal MgGAS; thus, it is critical that the physician assist the patient in understanding the outcomes and potential morbidity of the procedures to make the most informed decision. We envision that the future of MgGAS will advance with refinement of surgical techniques that minimize complications, improvement of tissue therapeutic technologies, new surgical tools and prosthetics designed for gGAS, advances in aftercare, and an immense selection of surgical options.

Narrative review of penile prosthetic implant technology and surgical results, including transgender patients

Over the past 40 years, the technological and surgical advancements in penile prostheses have led to increased patient satisfaction rates and decreased complication and infection rates. In cis males with erectile dysfunction (ED), these technological improvements tremendously improve quality of life. In female to male transgender patients, prostheses provide the ability to engage in penetrative intercourse and to urinate standing. This review evaluates technological and surgical advancements in penile prosthetics in the context of documented patient satisfaction and complication rates from prosthesis surgeries. Retrospective studies of penile implant usage in female to male gender-affirming surgeries report that infection and complication rates are higher than those seen in cis males. There are newer prostheses developed specifically for female to male reassignment surgeries, but outcome data is limited. Continued research and development are needed to develop more efficacious penile implantation options for gender affirmation surgery.

Total phallic construction techniques in transgender men: an updated narrative review

From 2012, the World Professional Association Transgender Health defined a structured therapeutic path and standards of care for transgender patients undergoing genital gender affirming surgery (GGAS). The main goal of GGAS in transgender males is to provide patients with an aesthetically appealing appearance of the neophallus that should allow standing micturition and enabling penetrative intercourse along with erogenous and tactile sensitivity. The optimal procedure should be safe, reproducible and performed in the fewest number of surgical stages. The ideal technique for total phallic construction (TPC) has not yet been demonstrated; TPC remains challenging and, from a functional point of view, it is also make more demanding as yet there are no perfect replacement materials for erectile and urethral tissues. Several procedures and different type of flaps (pedicled and free-flaps) have been proposed and investigated over time to address TPC with significant advances over the years especially after microsurgical procedures introduction. Due to its high complexity TPC is not free from complications. Local tissue ischaemic complications, complete and partial flap loss, donor site morbidity and urethral complications (fistulae and strictures) are reported. This narrative review aims to provide the readers with a contemporary overview of surgical procedures for TPC in transgender males focusing on key surgical steps, as well as surgical and functional outcomes.

Surgical techniques of phalloplasty in transgender patients: a systematic review

Gender confirmation surgery has a crucial role among transgender individuals. Phalloplasty is a procedure that uses flaps for phallic shaft creation. Flaps can be classified in free flaps or pedicle flaps and can be obtained from different donor sites such as forearm, thigh, abdomen, groin, and leg, and upper back. We conducted a systematic review about surgical flaps for phallic shaft creation in transgender patients. A systematic review was conducted on PubMed/MEDLINE, Cochrane Clinical Answers, and Cochrane Central Register of Controlled Trials databases without timeframe limitations. Exclusion criteria included articles that reported phalloplasty on patients other than transgender, as well as other surgical techniques such as urethroplasty, vaginectomy, hysterectomy and studies focused on psychosocial outcomes. Two hundred twenty-eight potential articles were identified in the initial search. Forty-one studies fulfilled the inclusion and exclusion criteria. Surgical flaps for phallic shaft creation in transgender patients were reported on 1,391 cases. Microsurgical flaps were the most common (24 of 33). The flap technique most frequently described was radial forearm flap (15 of 33) followed by Anterolateral thigh flap (7 of 33), Latissimus dorsi flap (5 of 33), abdominal flap (4 of 33), fibular flap (3 of 33), and groin flaps (3 of 33). The literature on surgical flaps for phallic shaft creation in transgender patients reflected how challenging the reconstruction of the phallus is. In summary, there is no universal choice of flap that could be applied to every patient. Therefore, the surgical approach must be chosen considering surgeon experience, physical examination, and patient desire. We hope this review supports future studies on surgical flaps for phallic shaft creation in transgender patients.

Current Status for Semirigid Penile Prosthetic Devices

PURPOSE OF REVIEW

The goal of this paper was to evaluate the current use of semirigid penile prosthesis (SRPP), surgical techniques for insertion of SRPP, and how to prevent and approach surgical complications.

RECENT FINDINGS

SRPP is a valid option for those who are refractory to medical therapy for erectile dysfunction (ED) and even more appropriate for specific subsets of patient populations. It is important for urologists to know which patient population SRPP is preferred for. Several studies have shown good patient outcomes and patient satisfaction with those who underwent SRPP.

Penile Cancer: Managing Sexual Dysfunction and Improving Quality of Life After Therapy

PURPOSE OF REVIEW

To review the most current literature on how the treatment for penile cancer can affect quality of life and to discuss current treatment options to overcome sexual dysfunction and ultimately improve patient wellbeing.

RECENT FINDINGS

Multiple medical and surgical therapies exist to address the high incidence of sexual dysfunction following penile cancer treatment. Advancements and refinements in the neophalloplasty, penile prosthesis, and penile lengthening procedures have opened the door to improved long-term outcomes. Additionally, studies continue to highlight the severe psychological toll that penile cancer treatment can have on patients. We explore the potential options for addressing the inherent psychologic effects of these treatments and highlight the need for further research in this domain. Although rare, it is important for all urologists to be familiar with the treatments and post-treatment sequelae of penile cancer. Penile cancer is associated with dramatic decline in quality of life and sexual function. Multiple medical and surgical therapies exist that addresses these concerns. Additionally, urologists must also be mindful of the psychologic component regarding surgical disfigurement and the decline in sexual function.

Suprapubic pedicled phalloplasty in transgender men: a multicentric retrospective cohort analysis

A variety of approaches are available to address a genital gender affirming surgery (GGAS) in transgender men. The aim of the present study is to report surgical and functional outcomes after a suprapubic pedicled phalloplasty (SPP). From November 2008 to August 2018, a consecutive series of 34 patients underwent an SPP in two tertiary referral centers. GGAS was conducted as a multistaged procedure, consisting (1) SPP with subsequent radial artery-based forearm free-flap urethroplasty, (2) glans sculpting, urethral anastomosis, and scrotoplasty, and (3) penile prosthesis implantation. The duration of surgery, intra and postoperative complications, and hospital stay were selected as variables for surgical outcomes. Functional outcomes were extrapolated from a four-item questionnaire.A partial necrosis of phallus was detected in two cases (5.8 %). Two cases of seroma formation with wound dehiscence (5.8%) were detected. Overall, 89% of patients declared to be fully satisfied of the SPP, 83% would recommend the procedure to someone else, and 89% would undergo the same procedure again. Overall, 66% of patients could achieve an orgasm during sexual penetrative intercourses. The retrospective design, the lack of randomization and validated questionnaire for outcomes reporting, and the limited follow-up represent the main drawbacks of our study. Our evidences suggest that SPP represents as an acceptable option for GGAS.

Latissimus dorsi free flap phalloplasty: a systematic review

A phalloplasty is a complex genital reconstruction procedure of creating a neophallus. Several techniques to create a neophallus are described, based on different vascularized flaps, and each of them has its advantages and drawbacks. The aim of this study is to present musculocutaneous latissimus dorsi (MLD) flap as a viable option for total phalloplasty, with an interest in clinical outcomes and complications. A comprehensive literature review of all available reports about MLD flap phalloplasty was made. The following keywords were used on PubMed: latissimus dorsi musculocutaneous/myocutaneous free flap and phalloplasty. Research criteria revealed five articles and the results of 182 patients were analyzed. A total number of the patients, indications, operative technique, follow-up period, postoperative results, and complications were presented. In conclusion, MLD free flap presents a good choice for phalloplasty providing sufficient amount of tissue for safe implantation of penile prosthesis and successful penetrative sexual intercourse. The erogenous sensitivity is preserved with clitoris or glans penis incorporated into the base of the neophallus, and voiding in a standing position is achievable after urethral reconstruction. The main drawback is the lack of tactile sensation of the neophallus and the significant advantage is a well-concealed donor site.

Total Phallic Reconstruction in the Genetic Male

BACKGROUND

Total phallic reconstruction (TPR) is a reconstructive challenge.

OBJECTIVE

To report both surgical outcomes and patient-reported outcomes (PROs) of genetic male patients undergoing TPR utilising a radial artery forearm free flap (RAFFF).

DESIGN, SETTING, AND PARTICIPANTS

A retrospective tertiary referral centre analysis of a series of genetic male patients with penile insufficiency (PI) either due to congenital micropenis, or from traumatic or surgical amputation was conducted.

SURGICAL PROCEDURE

RAFFF phalloplasty was conducted as a multistaged procedure: (1) TPR, (2) glans sculpting with second-stage urethroplasty when indicated, and (3) penile prosthesis implantation.

MEASUREMENTS

A descriptive analysis of the patient's baseline features, surgical outcomes, and PROs was conducted.

RESULTS AND LIMITATIONS

A total of 108 patients were enrolled. The median age was 32.5 yr (interquartile range [IQR] 24-46) and median follow-up was 78.5 mo (IQR 30-129). A primary anastomotic urethroplasty was performed in 90 patients (83.4%) and a staged procedure in the remainder. Four patients experienced an acute arterial thrombosis, leading to complete loss of the phallus in two. Immediate surgical exploration saved the flap in two cases of venous thrombosis. Urethral complication occurred in 49.1% of patients. The multivariate logistic regression analysis showed an association (p=0.04) between the staged urethral reconstruction and the incidence of urethral complications. The limitations of our study are its retrospective nature and the lack of control.

CONCLUSIONS

Despite the high incidence of postoperative complications and the possible need for revisions, TPR in the genetic male with PI using a RAFFF yields satisfactory aesthetic and functional results. PATIENT SUMMARY: in this report, we looked at the outcomes from TPR in a large population of male patients with penile inadequacy either due to congenital micropenis, or from traumatic or surgical amputation. Our results support the idea that penile reconstruction with a forearm free flap leads to satisfactory outcomes.

The First Experience of Using the Pedicled Labia Minora Flap for Urethral Lengthening in Transgender Men Undergoing Anterolateral Thigh and Superficial Circumflex Iliac Artery Perforator Flap Phalloplasty: A Multicenter Study on Clinical Outcomes

OBJECTIVE

To describe the novel surgical technique of urethral lengthening in anterolateral thigh and superficial circumflex iliac artery perforator flap phalloplasty with a pedicled labia minora flap (PLMF) and report on the clinical outcomes.

METHODS

Between March 2014 and August 2018, 16 transgender men underwent phalloplasty with a PLMF for urethral lengthening at the Amsterdam UMC (VU university), the Netherlands and the Belgrade University Hospital, Serbia. Patient demographics, surgical characteristics, neourethra characteristics, intra- and postoperative complications, pre-and postoperative voiding evaluation, and the length of hospital stay were retrospectively identified from chart reviews.

RESULTS

The mean neourethral length was 16.8 ± 2.3 cm, and the pars pendulans 11.7 ± 2.2 cm. The neomeatus was localized on top of the neophallus in 12 (75%) patients. No intraoperative complications occurred. Urethral fistula formation occurred in 4 (25%) patients and strictures in 6 (37.5%) patients. In 3 (18.7%) patients a (temporary) perineostomy had to be performed. Voiding from a standing position was possible in 9 (56.3%) patients.

CONCLUSION

The PLMF for urethral reconstruction, both pars fixa and pars pendulans, in phalloplasty is a feasible surgical technique in transgender men undergoing anterolateral thigh or superficial circumflex iliac artery perforator flap phalloplasty with sufficient labia minora tissue.

Localized disease: types of reconstruction/plastic surgery techniques after glans resurfacing/glansectomy/partial/total penectomy

PURPOSE OF REVIEW

The aim of this article is to provide an overview of the current literature specific to surgery for localized penile cancer including novel reconstructive techniques.Centralization of penile cancer services in many European countries and in particular the United Kingdom has resulted in an increased proportion of men undergoing organ-sparing surgery (OSS) rather than partial or total penectomy. In this review, we focus on reconstructive techniques following surgery for the primary penile tumour.

RECENT FINDINGS

The widespread adoption of penile preserving techniques in Europe and North America has shown both oncological safety as well as good cosmetic and functional outcomes. Recent evidence has suggested that narrower surgical margins do not affect overall cancer-specific survival or local recurrence rates. Therefore, excellent cosmetic and functional outcomes can be achieved using techniques such as glans resurfacing using split-thickness skin grafts, dorsal or ventral V-Y skin advancement and urethral centralization after partial penectomy. For patients requiring more radical surgery such as total penectomy, phallic reconstruction is a suitable option using free flaps or pedicled flaps.

SUMMARY

The use of OSS has transformed the lives of penile cancer patients who can avoid the significant clinical and psychological consequences of more radical surgical treatments. Careful case selection and preoperative counselling is advised prior to reconstructive techniques. Close postoperative clinical surveillance is necessary for early detection of local recurrence.

Metoidioplasty

Gender affirmation surgery for transmale patients is still challenging, as creation of the neophallus is one of the most demanding steps in surgical treatment. Metoidioplasty, as a one-stage procedure, can be considered in patients who desire gender affirmation surgery without undergoing a complex, multistage procedure with creation of an adult-sized neophallus. Metoidioplasty presents one of the variants of phalloplasty for patients in whom the clitoris is large enough under testosterone treatment. Advanced urethral reconstruction provides low complication rates with satisfying results of standing micturition.

Metoidioplasty: techniques and outcomes

Phalloplasty represents the latest step in female-to-male transitioning and still remains a great challenge for transgender surgeons. Since we have two options in this transitioning-metoidioplasty and total phalloplasty-the transgender surgeon has to fully inform the individual about all aspects such as surgical steps, outcomes, advantages and disadvantages, possible complications, and expectations. Total phalloplasty with the creation of a neophallus of a similar volume to that in genetic males, is a complex and multi-staged procedure. Many different tissues (i.e., flaps) can be used, and the ideal procedure is still not established. In contrast to the above complexities involved in total phalloplasty, metoidioplasty presents a simple and one-stage procedure for the creation of a neophallus from a hormonally enlarged clitoris. This technique is very promising for individuals who desire gender-affirmation surgery without having to undergo the difficult and multistage creation of a male-sized neophallus. Also, this technique prevents scarring to the extragenital region, making the final results more acceptable for transgender individuals. Our goal is to objectively present the techniques for metoidioplasty and to define their value based on postoperative results.
