Penile reconstruction/formation

Overview of Medical Management of Transgender Men: Perspectives from Sri Lanka

Transgender medicine is an evolving field of medicine due to the rising awareness of individuals with a non-binary gender identity. Individuals with nonconforming gender identities have been on the rise in many societies and it is becoming an increasingly discussed issue. Their management is multidisciplinary, which includes mental health, endocrine therapy, and surgery. Although their general healthcare needs are similar to those of the general population, special considerations in primary and preventive care are also necessary in relation to the gender-affirming medical issues. Their quality of life is largely affected by psychological, social, and economic difficulties they face due to acceptance issues in the society and healthcare. This review explores the primary care, medical, and surgical management of transgender men with perspectives from Sri Lanka.

Neo-phalloplasty in children and adolescents for acquired penile loss

INTRODUCTION

From 2000 to 2019, the De Castro's neo-phalloplasty was used in 47 patients with congenital and acquired penile loss.

PURPOSE

Herein, the technical aspects of penile reconstruction and the outcomes in 17 children and adolescents treated for total or sub-total acquired penile loss are reported.

MATERIAL AND METHODS

The median age at the time of injury was 3 months (range: 2 days-15 years). Twelve patients were born with normal penis but suffered injuries (11) or underwent surgical resection of the penis (1). The remaining 5, affected by bladder exstrophy (2) or cloacal exstrophy (3), had penile loss due to surgical complications.

RESULTS

The median age at the time of surgery was 5 years (range: 2-20 years). The median length of the procedure was 5 h (range 4-8 h). Skin expander were inserted in preparation of phalloplasty in 9 patients. Corpora-cavernosa remnants were found and incorporated in the neophallus in 12 patients. In 7 patients, urethral remnants were also incorporated into the repair, placing the meatus at the tip of the neophallus. In the remaining patients the urethra was left in the acquired position after penile loss creating a perineal (2), scrotal (3), peno-scrotal (3), or posterior penile (1) urethrostomy. The first patient of this series was the only patient to receive simultaneously phalloplasty and total urethroplasty, with failure of urethral reconstruction. The median follow-up was 2 years (range 1-11 years). The overall complication rate was about 47%. All of the complications were late and required surgical revision. The results were assessed regarding overall functionality (voiding, erection/erogenous areas, masturbation/sexual intercourse) and aesthetic outcome using subjective and objective parameters. Psychological evaluation for both patient and parents was performed in 4 cases.

DISCUSSION

There are no specific guidelines for treating significant penile injuries in the pediatric population. We do not think secondary severe penile impairments should wait until adult age for repair. In this specific subgroup of patients technical aspects differ from phalloplasty done for congenital aphallia, due to the possible presence of corpora-cavernosa/urethral remnants and the feasibility to perform a "functional phalloplasty" with very encouraging results.

CONCLUSION

The De Castro's neo-phalloplasty remains one of the few techniques available for total penile reconstruction in pediatric age group. Data demonstrate that this technique for acquired aphallia is feasible and reproducible, however, it is a challenging procedure with a high complication rate and likelihood of revisions.

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.

MicroRNA-126 engineered muscle-derived stem cells attenuates cavernosa injury-induced erectile dysfunction in rats

BACKGROUND

Cavernosa injury is a common cause of organic erectile dysfunction (ED), which requires safe and effective treatments. In the present study, the therapeutic efficiency of muscle-derived stem cells (MDSCs) modified with microRNA-126 (miR-126) was determined in rats with cavernosa injury.

METHODS

MDSCs were transfected with miR-126 and then were transplanted into rats with cavernosa injury. Erectile function, vascular function (western blot and immunofluorescence), extraction, and detection of exosomes were then undertaken.

RESULTS

On the 28th day after transplantation, the highest value of intra-cavernous pressure (ICP)/mean arterial pressure (MAP) in rats of miRNA-126 group (0.84 ± 0.14) was observed (Control: 0.38 ± 0.07; MDSC: 0.54 ± 0.11, Vector: 0.60 ± 0.02; respectively). Treatment of miRNA-126-modified-MDSCs remarkably strengthened vascular structure, supported by hematoxylin-eosin staining. The expression of CD31, von Willebrand Factor and vascular endothelial factors were higher than those in other groups, indicating improved vascular function. In vitro mechanism studies showed that exosomes containing miR-126 isolated from MDSCs promoted angiogenesis and attenuated apoptosis of human umbilical venous endothelial cells. Finally, insulin receptor substrate 1 and Krüppel-like factor 10 were determined as the direct target genes of miR-126.

CONCLUSIONS

MiR-126 engineered MDSCs notably repaired cavernosa injury in rats via vascular reconstruction by directly targeting IRS1 and KLF10, in which the exosomes secreted by MDSCs played a critical role.

A pilot retrospective CT angio study of the internal pudendal arteries in male bodies, for the purpose of penis transplantation to trans men

Literature reports four successful cases where penile transplantation has been performed for cis men. To date, no penis transplantation has ever been attempted for trans men. Modern surgical techniques for penis reconstruction for (trans) men with gender incongruence present multiple drawbacks, and sometimes fail to meet patients' expectations. Penis transplantation could represent an alternative solution. With the aim of planning penis transplantation to trans men, a previous study from our same group suggested a surgical technique for explantation of penis and associated vessels, nerves and urethra en-bloc from a cadaver: further radiographic imaging of vascular anatomy was recommended. To measure length and diameter of the internal pudendal arteries at three set points in biological males, in order to confirm its viability for transplantation. A retrospective examination of existing CT images visualizing the internal pudendal arteries in 12 bodies, assigned male at birth, was performed. Diameters were measured in three points: 1. the take off of the artery; 2. distal to its rectal branch; and, 3. at the bifurcation of the two terminal branches of the artery, i.e. the bulbourethral artery and the dorsal artery of the penis. Mean diameters of the selected points were 2.4 mm, 1.9 mm, and 1.5 mm on both sides. Mean lengths of internal pudendal arteries were 111.2 mm on the left, and 120.1 mm on the right side. Diameters of the internal pudendal artery is sufficient for arterial anastomosis at all measured points. Lengths are sufficient to reach recipient vessels.

Male genital sensation after spinal cord injury: a review

Genital sensation (GS) is an essential component of male sexual function. Genital sensory disturbance (GSD) caused by spinal cord injury (SCI) has a severe impact on the patients' sexual function but has garnered little research focus. Under normal conditions, GS encompasses the erection, ejaculation, sexual arousal, and orgasm courses associated with physiological and psychological responses in male sexual activity. However, in SCI patients, the deficiency of GS makes the tactile stimulation of the penis unable to cause sexual arousal, disturbs the normal processes of erection and ejaculation, and decreases sexual desire and satisfaction. To provide an overview of the contemporary conception and management of male GS after SCI, we review the innervation and sexual function of male GS in this article, discuss the effects of GSD following SCI, and summarize the current diagnosis and treatment of GSD in male SCI patients.

Construction of engineered corpus cavernosum with primary mesenchymal stem cells in vitro

Various methods have been used to reconstruct the penis. The objective of this study was to investigate the feasibility of constructing engineered corpus cavernosum with primary mesenchymal stem cells (MSCs) in a rabbit model in vitro. Acellular corporal matrices (ACMs) were obtained from adult rabbit penile tissues through an established decellularization procedure. MSCs were separated, purified, and then seeded on ACMs to construct engineered corpus cavernosum. The seeded ACMs were subsequently cultured in an incubator for 14 days. Histological analyses showed that MSCs seeded on the ACMs had proliferated and were well distributed. Detection of CD31, vWF, smooth muscle actin (SMA), and myosin protein as well as vWF and myosin mRNA revealed that the MSCs had differentiated into endothelial cells and smooth muscle cells. In addition, cell morphology of the engineered corpus cavernosum was directly observed by transmission electron microscopy. This study demonstrated that engineered corpus cavernosum could be successfully constructed using primary MSCs in vitro. This technology represents another step towards developing engineered corpus cavernosum in vitro.

Endocrine Treatment of Gender-Dysphoric/Gender-Incongruent Persons: An Endocrine Society Clinical Practice Guideline

OBJECTIVE

To update the "Endocrine Treatment of Transsexual Persons: An Endocrine Society Clinical Practice Guideline," published by the Endocrine Society in 2009.

PARTICIPANTS

The participants include an Endocrine Society-appointed task force of nine experts, a methodologist, and a medical writer.

EVIDENCE

This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation approach to describe the strength of recommendations and the quality of evidence. The task force commissioned two systematic reviews and used the best available evidence from other published systematic reviews and individual studies.

CONSENSUS PROCESS

Group meetings, conference calls, and e-mail communications enabled consensus. Endocrine Society committees, members and cosponsoring organizations reviewed and commented on preliminary drafts of the guidelines.

CONCLUSION

Gender affirmation is multidisciplinary treatment in which endocrinologists play an important role. Gender-dysphoric/gender-incongruent persons seek and/or are referred to endocrinologists to develop the physical characteristics of the affirmed gender. They require a safe and effective hormone regimen that will (1) suppress endogenous sex hormone secretion determined by the person's genetic/gonadal sex and (2) maintain sex hormone levels within the normal range for the person's affirmed gender. Hormone treatment is not recommended for prepubertal gender-dysphoric/gender-incongruent persons. Those clinicians who recommend gender-affirming endocrine treatments-appropriately trained diagnosing clinicians (required), a mental health provider for adolescents (required) and mental health professional for adults (recommended)-should be knowledgeable about the diagnostic criteria and criteria for gender-affirming treatment, have sufficient training and experience in assessing psychopathology, and be willing to participate in the ongoing care throughout the endocrine transition. We recommend treating gender-dysphoric/gender-incongruent adolescents who have entered puberty at Tanner Stage G2/B2 by suppression with gonadotropin-releasing hormone agonists. Clinicians may add gender-affirming hormones after a multidisciplinary team has confirmed the persistence of gender dysphoria/gender incongruence and sufficient mental capacity to give informed consent to this partially irreversible treatment. Most adolescents have this capacity by age 16 years old. We recognize that there may be compelling reasons to initiate sex hormone treatment prior to age 16 years, although there is minimal published experience treating prior to 13.5 to 14 years of age. For the care of peripubertal youths and older adolescents, we recommend that an expert multidisciplinary team comprised of medical professionals and mental health professionals manage this treatment. The treating physician must confirm the criteria for treatment used by the referring mental health practitioner and collaborate with them in decisions about gender-affirming surgery in older adolescents. For adult gender-dysphoric/gender-incongruent persons, the treating clinicians (collectively) should have expertise in transgender-specific diagnostic criteria, mental health, primary care, hormone treatment, and surgery, as needed by the patient. We suggest maintaining physiologic levels of gender-appropriate hormones and monitoring for known risks and complications. When high doses of sex steroids are required to suppress endogenous sex steroids and/or in advanced age, clinicians may consider surgically removing natal gonads along with reducing sex steroid treatment. Clinicians should monitor both transgender males (female to male) and transgender females (male to female) for reproductive organ cancer risk when surgical removal is incomplete. Additionally, clinicians should persistently monitor adverse effects of sex steroids. For gender-affirming surgeries in adults, the treating physician must collaborate with and confirm the criteria for treatment used by the referring physician. Clinicians should avoid harming individuals (via hormone treatment) who have conditions other than gender dysphoria/gender incongruence and who may not benefit from the physical changes associated with this treatment.

Phalloplasty: A Review of Techniques and Outcomes

BACKGROUND

Acquired or congenital absence of the penis can lead to severe physical limitations and psychological outcomes. Phallic reconstruction can restore various functional aspects of the penis and reduce psychosocial sequelae. Moreover, some female-to-male transsexuals desire creation of a phallus as part of their gender transition. Because of the complexity of phalloplasty, there is not an ideal technique for every patient. This review sets out to identify and critically appraise the current literature on phalloplasty techniques and outcomes.

METHODS

A comprehensive literature search of the MEDLINE, PubMed, and Google Scholar databases was conducted for studies published through July of 2015 with multiple search terms related to phalloplasty. Data on techniques, outcomes, complications, and patient satisfaction were collected.

RESULTS

A total of 248 articles were selected and reviewed from the 790 identified. Articles covered a variety of techniques on phalloplasty. Three thousand two hundred thirty-eight patients underwent phalloplasty, with a total of 1753 complications reported, although many articles did not explicitly comment on complications. One hundred four patients underwent penile replantation and two underwent penile transplantation. Satisfaction was high, although most studies did not use validated or quantified approaches to address satisfaction.

CONCLUSIONS

Phalloplasty techniques are evolving to include a number of different flaps, and most techniques have high reported satisfaction rates. Penile replantation and transplantation are also options for amputation or loss of phallus. Further studies are required to better compare different techniques to more robustly establish best practices. However, based on these studies, it appears that phalloplasty is highly efficacious and beneficial to patients.

Regeneration of rat corpora cavernosa tissue by transplantation of CD133+ cells derived from human bone marrow and placement of biodegradable gel sponge sheet

The objective is to develop an easier technique for regenerating corpora cavernosa tissue through transplantation of human bone marrow-derived CD133 + cells into a rat corpora cavernosa defect model. We excised 2 mm × 2 mm squares of the right corpora cavernosa of twenty-three 8-week-old male nude rats. Alginate gel sponge sheets supplemented with 1 × 10 4 CD133 + cells were then placed over the excised area of nine rats. Functional and histological evaluations were carried out 8 weeks later. The mean intracavernous pressure/mean arterial pressure ratio for the nine rats (0.34258 ± 0.0831) was significantly higher than that for eight rats with only the excision (0.0580 ± 0.0831, P = 0.0238) and similar to that for five rats for which the penis was exposed, and there was no excision (0.37228 ± 0.1051, P = 0.8266). Immunohistochemical analysis revealed that the nine fully treated rats had venous sinus-like structures and quantitative reverse transcription polymerase chain reaction analysis of extracts from their alginate gel sponge sheets revealed that the amounts of mRNA encoding the nerve growth factor (NGF), and vascular endothelial growth factor (VEGF) were significantly higher than those for rats treated with alginate gel sheets without cell supplementation (NGF: P = 0.0309; VEGF: P < 0.0001). These findings show that transplantation of CD133 + cells accelerates functional and histological recovery in the corpora cavernosa defect model.

Acellular human glans extracellular matrix as a scaffold for tissue engineering: in vitro cell support and biocompatibility

Objectives:

Diseases of the genitourinary tract can lead to significant damage. Current reconstructive techniques are limited by tissue availability and compatibility. This study aims to assess if the decellularized human glans can be used as a biomaterial for penile reconstruction.

Materials and Methods:

Samples of the glans matrices were descellularized. We evaluate the presence of collagen type I and III, and elastic fibers. Biocompatibility assays were performed to assess the cytotoxic and non-cytotoxic interactions between the acellular matrix and 3T3 cells. The matrices were seeded with mesenchymal stem cells and were assessed for viability and integration of these cells. Biomechanical tests in native tissue, descellularized matrix and seeded matrix were performed to characterize their biomechanical properties.

Results:

The tissue architecture of the decellularized matrix of human glans was preserved as well as the maintenance of the biomechanical and biological properties. The analyzes of glans seeded with mesenchymal stem cells revealed the integration of these cells to the matrices, and its viability during two weeks “in vitro”.

Conclusion:

The decellularization process did not alter the biological and biomechanical characteristics of the human glans. When these matrices were seeded they were able to maintain the cells integrity and vitality.

Modification of the tube-in-tube pedicled anterolateral thigh flap for total phalloplasty: the mushroom flap

BACKGROUND

Malformation or absence of the penis can lead to physical and psychological problems for male patients. Reconstruction of the phallus should optimally be completed in a single procedure, be aesthetically pleasing, retain erogenous and tactile sensation, enable micturition in the standing position, and allow for penetrative sexual intercourse. The tube-in-tube flap was described nearly 30 years ago and forms both a urethra and an outer penile shaft with a single flap. Here we present our modification of the original tube-in-tube design with the pedicled anterolateral thigh (ALT) flap and an extension for the neoglans, which we have termed the "mushroom flap" because of its shape and design.

METHODS

The flap is based on the ALT flap; however, the area that will become the neoglans is shaped with a semicircular extension, resembling the head of a mushroom. When the flap is tubularized, the neoglans has the proper anatomic landmarks such as the corona and more closely approximates a circumcised penis. When used in conjunction with the tube-in-tube design, the neophallus, neoglans, and neourethra can all be constructed in a single stage with a single flap.

RESULTS

We have performed total phalloplasties in three patients using the pedicled ALT flap, and the mushroom flap design evolved as we sought to improve the aesthetics of the neoglans. In comparing the aesthetic results among our patients as well as those published in the literature, the mushroom flap design seems to provide the most natural and aesthetically pleasing appearance.

CONCLUSIONS

The pedicled ALT flap can be used to reconstruct an entire penis, as well as a urethra, without the need for microsurgery. By modifying the original tube-in-tube design to include a semicircular extension (a.k.a. the "mushroom flap"), we feel that we have been able to achieve a more natural-appearing neoglans.

The role of mental health professionals in gender reassignment surgeries: unjust discrimination or responsible care?

OBJECTIVE

Recent literature has raised an important ethical concern relating to the way in which surgeons approach people with gender dysphoria (GD): it has been suggested that referring transsexual patients to mental assessment can constitute a form of unjust discrimination. The aim of this paper is to examine some of the ethical issues concerning the role of the mental health professional in gender reassignment surgeries (GRS).

METHOD

The role of the mental health professional in GRS is analyzed by presenting the Standards of Care by the World Professional Association of Transgender Health, and discussing the principles of autonomy and non-discrimination.

RESULTS

Purposes of psychotherapy are exploring gender identity; addressing the negative impact of GD on mental health; alleviating internalized transphobia; enhancing social and peer support; improving body image; promoting resilience; and assisting the surgeons with the preparation prior to the surgery and the patient's follow-up. Offering or requesting psychological assistance is in no way a form of negative discrimination or an attack to the patient's autonomy. Contrarily, it might improve transsexual patients' care, and thus at the most may represent a form of positive discrimination. To treat people as equal does not mean that they should be treated in the same way, but with the same concern and respect, so that their unique needs and goals can be achieved.

CONCLUSIONS

Offering or requesting psychological assistance to individuals with GD is a form of responsible care, and not unjust discrimination.

Postoperative imaging of phalloplasties and their complications

OBJECTIVE

In this article, we summarize the common phalloplasty indications, surgical techniques, and relevant anatomy. We review the appropriate imaging techniques used in postoperative evaluation of the neophallus and illustrate the postoperative appearance and complications associated with phalloplasty.

CONCLUSION

Phalloplasty is an infrequently encountered yet complex procedure requiring careful postoperative imaging assessment. Modern microsurgical techniques have made free flaps the reference standard in phalloplasty, and the radiologist must be aware of the expected postoperative appearance and complications to appropriately manage these patients.

Titanium-bone-anchored penile epithesis: preoperative planning and immediate postoperative results

The principle of osseointegration is accepted and used in reconstructive surgery. This study presents the first series of five patients where titanium implants have been implanted into the pubic bones of female-to-male (FTM) transsexual patients, in order to attach a "bone-anchored" penile epithesis. Following patient selection based on patients' wishes, pubic bones of 10 FTM transsexuals were analysed by CT-scan and a virtual planning was made. A surgical plan was also developed. To date, five FTM transsexuals have undergone the two-stage surgery. During stage-1, two titanium implants ("fixtures") are implanted onto the pubic bone. Four weeks postop, a new CT scan is performed to analyze osseointegration and the final implant position. During stage-2, the soft tissue of the pubic area is reduced; abutments are inserted and passed through the skin. A few weeks after stage 2 surgery, a penile epithesis is connected to the skin-penetrating titanium implants. Two out of 10 patients who received preoperative CT scan presented with smaller pubic bones, not able to accommodate the fixtures as chosen originally. Preoperative virtual planning is crucial for the selection of the appropriate implants size. The stage-1 and stage-2 surgery occurred uneventfully in all five patients. One patient presented with a wound infection 1 week after stage-2 surgery. Postoperative CT scan demonstrates implant osseointegration in all cases. This experimental clinical study demonstrates that titanium osseointegration is feasible onto the pubic bone. This new approach for penile reconstruction constitutes another alternative for both transsexual patients and cases following genital development disorders, post-trauma and surgery.

Sex reassignment surgery for transsexuals

PURPOSE OF REVIEW

The purpose of this article is to report on the most recent findings on the current surgical treatments for sex reassignment surgery for both male-to-female and female-to-male transsexuals.

RECENT FINDINGS

For male-to-female sex reassignment surgery, researches aim to refine the inverted peno-scrotal flap surgical technique in order to increase the neovaginal length and width, prevent complications and ameliorate the cosmetic outcome.Bowel segment vaginoplasty, used mainly for secondary cases, is becoming more and more common.For female-to-male sex reassignment surgery, the radial forearm flap is the only procedure that has proved to fulfil most of the patient expectations; however, because of a high complications rate, long recovery time and a large number of the required operations, and the absence of guarantee that patients will be satisfied, the free radial forearm flap is not the best option for every patient. Alternatives such as abdominal/groin flap, thigh flap and metaidoioplasty are very much used.

SUMMARY

In order to provide the best care for transsexual patients, centres performing sex reassignment surgery should co-operate and implement both the refinements and the new techniques offered and/or requested.

Preconstruction of the Pars Pendulans Urethrae for Phalloplasty with Digestive Mucosa Using a Prefabricated Anterolateral Thigh Flap in a One-arm Patient

Summary:

We herein report a successful preconstruction of the pars pendulans urethrae with the ileum mucosa for phalloplasty in a one-arm patient using a prefabricated anterolateral thigh flap. After a 2-stage operation and an 18-month follow-up, the patient achieved a good postoperative appearance and an excellent function of neophallus. We believe the use of digestive mucosa for urethral reconstruction enlightens us and deserves further comprehensive clinical studies.

"Bird-Wing" abdominal phalloplasty: A novel surgical technique for penile reconstruction

Aim:

To describe a technique of phalloplasty that is devoid of donor site scarring and suitable for urethral inlay and penile prosthesis in subsequent stages in cases of aphallia.

Materials and Methods:

Four patients with various disorders of sex development with 46 XY and severe penile deficiency, including one with complete androgen insensitivity syndrome who was initially raised as female, have been operated using a “Bird Wing” lower abdominal skin crease incision.

Results:

The patients’ age ranged from 6 to 17 years with preoperative stretched penile lengths between 1 and 2.5 cm. Phallic sizes between 7.5 and 12.5 cm was achieved leaving the donor site unremarkable with lower abdominal skin crease linear scar and excellent postoperative recovery.

Conclusions:

This phalloplasty technique can be utilized as a definitive procedure in many situations of penile insufficiency. Subsequent stages of urethral repair and insertion of penile prosthesis can be easily added.

The 2011 WPATH Standards of Care and Penile Reconstruction in Female-to-Male Transsexual Individuals

The World Professional Association for Transgender Health (WPATH) currently publishes the Standards of Care (SOC), to provide clinical guidelines for health care of transsexual, transgender and gender non-conforming persons in order to maximize health and well-being by revealing gender dysphoria. An updated version (7th version, 2011) of the WPATH SOC is currently available. Differences between the 6th and the 7th versions of the SOC are shown; the SOC relevant to penile reconstruction in female-to-male (FtM) persons are emphasized, and we analyze how the 2011 WPATH SOC is influencing the daily practice of physicians involved in performing a penile reconstruction procedure for these patients. Depending by an individual's goals and expectations, the most appropriate surgical technique should be performed: the clinic performing penile reconstruction should be able to offer the whole range of techniques, such as: metoidioplasty, pedicle and free flaps phalloplasty procedures. The goals that physicians and health care institutions should achieve in the next years, in order to improve the care of female-to-male persons, consist in: informing in details the individuals applying for penile reconstruction about all the implications; referring specific individuals to centers capable to deliver a particular surgical technique; implementing the surgery with the most updated refinements.

De Castro technique used to create neophallus: a case of aphallia

We report on a rare case of aphallia in an X, Y-born male treated at our institution. The child underwent phalloplasty at 5 years of age using the De Castro phalloplasty technique and an abdominal skin flap. Although moderate distal necrosis was seen, the overall immediate and 12-month postoperative results were highly encouraging for our patient. Thus, this technique should be seen as a temporizing reconstructive option for patients with aphallia. Long-term follow-up is necessary to determine whether the neophallic size augments with axial growth and the need for additional intervention to facilitate onset of sexual activity.

Gender reassignment surgery: an overview

Gender reassignment (which includes psychotherapy, hormonal therapy and surgery) has been demonstrated as the most effective treatment for patients affected by gender dysphoria (or gender identity disorder), in which patients do not recognize their gender (sexual identity) as matching their genetic and sexual characteristics. Gender reassignment surgery is a series of complex surgical procedures (genital and nongenital) performed for the treatment of gender dysphoria. Genital procedures performed for gender dysphoria, such as vaginoplasty, clitorolabioplasty, penectomy and orchidectomy in male-to-female transsexuals, and penile and scrotal reconstruction in female-to-male transsexuals, are the core procedures in gender reassignment surgery. Nongenital procedures, such as breast enlargement, mastectomy, facial feminization surgery, voice surgery, and other masculinization and feminization procedures complete the surgical treatment available. The World Professional Association for Transgender Health currently publishes and reviews guidelines and standards of care for patients affected by gender dysphoria, such as eligibility criteria for surgery. This article presents an overview of the genital and nongenital procedures available for both male-to-female and female-to-male gender reassignment.

Iatrogenic trapped penis in adults: new, simple 2-stage repair

PURPOSE

We present a new, 2-stage functional and cosmetic reconstruction of concealed penis in adults with short-term subjective outcomes.

MATERIALS AND METHODS

Patients with excess penile skin removal, shaft tissue scarring and penile retraction with poor functional and cosmetic results underwent 2-stage repair. At stage 1 after a coronal incision and penile degloving an intrascrotal tunnel was formed and the penis was transposed through the scrotum. Three or 4 zero or 2-zero nonresorbable sutures were applied ventral to the penis, crossing through the entire scrotum to ensure complete scrotal skin adhesion to the penis (penile scrotalization). At stage 2 after 6 to 12 weeks the scrotal skin at the penile base was incised bilaterally to separate the skin around the penis from the remaining scrotal skin (penile descrotalization). Evaluation was scheduled 3, 6 and 9 months postoperatively, and annually thereafter.

RESULTS

Ten men with concealed penis underwent this 2-stage penile repair, including 8 who were circumcised and 2 who underwent conservative surgery for penile cancer. Mean +/- SD operative time was 75 +/- 15 minutes for stage 1 and 45 +/- 10 minutes for stage 2. No major intraoperative or perioperative complications occurred except superficial scrotal hematoma in 1 patient. At a median followup of 20 months (range 6 to 72) all men were in satisfactory clinical condition and the median patient satisfaction visual analog score was 97 (range 85 to 100). All patients recovered normal spontaneous erection with regular sexual intercourse 4 to 8 weeks after operation 2.

CONCLUSIONS

This simple, new 2-stage technique seems feasible and effective, and it is well accepted by patients. Further studies are mandatory to confirm preliminary results.

Aphallia: experience with 3 cases

In view of the rarity of the lesion, we describe 3 cases of aphallia associated with genitourinary and nongenitourinary anomalies. One case was associated with an anorectal malformation, whereas 2 had a normal anal opening. One patient with a normal anal opening had an associated rectal-urethro-fistula. Development of the phallus, clinical presentation of aphallia, associated anomalies, and an outline of the management is discussed along with a review of the literature.
