Abstract
The penis is a complex organ with a development cycle from the fetal stage to puberty. In addition, it may suffer from either congenital or acquired anomalies. Penile surgical reconstruction has been the center of interest for many researchers but is still challenging due to the complexity of its anatomy and functionality. In this review, penile anatomy, pathologies, and current treatments are described, including surgical techniques and tissue engineering approaches. The self-assembly technique currently applied is emphasized since it is considered promising for an adequate tissue-engineered penile reconstructed substitute.

Abstract
Background Every year, more than 90,000 U.S. women undergo mastectomy. More than 40% have reconstruction. Following reconstruction, most women experience persistent partial or complete numbness of the reconstructed breasts, and many experience pain. Yet, breast reconstruction procedures focus largely on esthetic outcomes with mixed impact on sensory outcomes and little attention to pain. This study examines whether and how breast sensation is important to women. Materials and Methods Conventional content analysis of extant qualitative data from a clinical registry (29 women with prior breast surgery for cancer, 2008-2022), a volunteer community sample (qualitative interviews with 6 women with and 5 without breast cancer, 2019), and from a Twitter social media survey (N = 32, 2022). Results Functions of the breast identified by women with and without cancer include breastfeeding, sexual function, and femininity. Five interrelated themes on the importance of breast sensation emerged among women with breast cancer history: sexual function, experience of partnered sex or relationship with one's sexual partner, breast embodiment, effect of breast pain on sexual function, and importance to psychological wellbeing. Women, advocates, and clinicians described a lack of patient-physician communication in this domain that exacerbates the negative impact of breast sensation loss on health and wellbeing. Conclusions Breast sensation is important to women following mastectomy, yet a gap exists in patient-physician communication about the impact of mastectomy and reconstruction on breast sensory function. Lessons for physicians, scientists, and skeptics are conveyed about why the basic integrity of women's bodies matters for practice and science.

Abstract
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.

Abstract
Acquired disorders and congenital defects of the male and female reproductive systems can have profound impacts on patients, causing sexual and endocrine dysfunction and infertility, as well as psychosocial consequences that affect their self-esteem, identity, sexuality, and relationships. Reproductive tissue engineering (REPROTEN) is a promising approach to restore fertility and improve the quality of life of patients with reproductive disorders by developing, replacing, or regenerating cells, tissues, and organs from the reproductive and urinary systems. In this review, we explore the latest advancements in REPROTEN techniques and their applications for addressing degenerative conditions in male and female reproductive organs. We discuss current research and clinical outcomes and highlight the potential of 3D constructs utilizing biomaterials such as scaffolds, cells, and biologically active molecules. Our review offers a comprehensive guide for researchers and clinicians, providing insights into how to reestablish reproductive tissue structure and function using innovative surgical approaches and biomaterials. We highlight the benefits of REPROTEN for patients, including preservation of fertility and hormonal production, reconstruction of uterine and cervical structures, and restoration of sexual and urinary functions. Despite significant progress, REPROTEN still faces ethical and technical challenges that need to be addressed. Our review underscores the importance of continued research in this field to advance the development of effective and safe REPROTEN approaches for patients with reproductive disorders.

Abstract
SUMMARY Total penile reconstruction represents a surgical challenge. Autologous reconstructions offer limited aesthetic results and variable urinary function recovery. To date, five genitourinary vascularized composite allotransplantations have been performed worldwide. However, in all cases, vascular complications have been reported. The objective of this study was to develop a modified surgical model for penile allotransplantation to limit the number of microsurgical anastomoses and ensure vascular reliability. The authors studied penile allotransplantation by performing dissections on 12 subjects. The study was carried out to ensure the vascularization of the entire penis shaft while limiting the number of anastomoses. The penis vasculature includes numerous angiosomes between its different subunits. The penile skin envelope is supplied by both external and internal pudendal vessels. The cavernous and spongy bodies are supplied by terminal branches of the internal pudendal vessels. The anterior pubic osteotomy approach allows access to the root of the cavernous bodies and to the Alcock ducts. This modified surgical model for penile allotransplantation could help future teams involved in genitourinary vascularized composite allotransplantations to improve urinary and sexual function. CLINICAL RELEVANCE STATEMENT The authors introduce an improved surgical technique for penile transplantation that enhances vascularization and graft viability. This innovative procedure optimizes blood flow through meticulous microsurgical anastomosis, resulting in improved functional outcomes. Its potential to revolutionize penile transplantation warrants further exploration and validation within the surgical community.

Abstract
We aimed to present our 20-year experience of using the deep inferior epigastric vessels as recipient vessels for free scapular flaps phalloplasty and evaluate the outcomes. Penile reconstruction was performed using a free scapular flap between 2000 and 2020 by the same surgical team. Deep inferior epigastric vessels were used in all the cases. The surgical techniques and outcomes were described. Overall, 73 patients used the deep inferior epigastric artery (DIEA) as the recipient artery. Regarding the recipient veins, 2 veins were anastomosed in 72 (98.6%) patients, 1 deep inferior epigastric vein (DIEV) was used in 1 patient, 2 DIEV in 14, 1 DIEV + superficial inferior epigastric vein (SIEV) in 13, 1 DIEV + superficial circumflex iliac vein (SCIV) in 38, great saphenous vein (GSV) + SCIV in 4, and GSV + SIEV in 3. The mean age and body mass index of the study cohort was 28 years and 24.3 kg/m2, respectively. The shortest follow-up time was 7 months. Eleven patients had flap-related complications. Three patients were readmitted to the operating room within 24 hours, and 2 of them underwent salvage procedures with venous revision. Two patients lost the entire flap. One patient with 3-cm distal portion necrosis required surgical intervention. Three patients experienced urethral necrosis. DIEA is a suitable receptor artery for inflow. The DIEV, SIEV, and SCIV are available options for venous drainage according to the patient anatomical characteristics. The GSV can be an excellent backup for outflow and salvage procedures.

Abstract
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.

Abstract
OBJECTIVE To evaluate the surgical and functional outcomes of urethral reconstruction associated with phalloplasty, depending on the surgical techniques and patient history. MATERIALS AND METHODS We conducted a single-centre retrospective study including 89 patients who underwent phalloplasty with urethral reconstruction between 2007 and 2018. Patients included were trans-male patients undergoing gender-affirming surgery and cis-male patients undergoing penile reconstruction after trauma, congenital malformation, or cancer. Urethral reconstructions were performed by free flap or skin graft (total or thin). Secondary urethroplasty may include direct vision urethrotomy, excision-anastomosis, or augmentation urethroplasty (skin graft, buccal mucosa graft). Patient demographics, medical history, peri- and postoperative data were collected from patient files. Functional results were evaluated using individual questionnaires. RESULTS The mean (±sd) follow-up duration was 5.5 (±3.7) years. No significant difference was found for total urethral complication rate (fistula and/or stricture) according to type of urethral construction (70.9% for free flap urethra vs 73.5% for skin graft urethra; P = 0.911), nor according to the patient's grounds for surgery (72.7% for cis-male vs 71.8% for trans-male patients; P = 1). A total of 36 patients (40.5%) answered the functional questionnaire, of whom 80.5% reported usually voiding while standing and 47.5% were comfortable with urinating in public. CONCLUSIONS Urethral construction in phalloplasty is associated with a high complication and revision rate regardless of the type of urethral reconstruction. Voiding in a standing position is generally possible but should not conceal feeble functional results.

Abstract
BACKGROUND Phalloplasty is a challenging procedure in the field of repair and reconstruction. Traditional skin flap methods with prostheses or autologous tissue implantation are still common; however, with this method the reconstructed phallus is static and has a high risk of complications. AIM We aimed to use novel methods for phalloplasty to mimic the normal structure of the phallus while maintaining the patient's ability to obtain sufficient hardness and subjective controllability. METHODS The neophallus comprised the bilateral pedicled neurovascular gracilis muscle, which provided neophallus volitional control; the pedicled fascia lata, which mimicked the tunica albuginea; the pedicled anterolateral thigh flap, which was used to reconstruct the neourethra and neoglans; and the thin split-thickness skin grafted on the surface of the fascia lata. The urethral anastomosis was performed simultaneously. The appearance and function of the neophallus, as well as patient satisfaction, were evaluated postoperatively. OUTCOMES The biomimetic dynamic phalloplasty using the bilateral pedicled gracilis muscle combined with the fascia lata was successfully performed in 4 patients. RESULTS During follow-up at 10-21 months after the procedure, all 4 patients could complete sexual intercourse and were satisfied with the appearance and self-controllability of the neophallus. The size of the neophallus stabilized within 6 months. The tactile, deep touch sensation, and pain sensations of the neophallus partially recovered. All of the patients could stand to urinate. CLINICAL IMPLICATIONS We used the gracilis muscle combined with the fascia lata to mimic the basic structure of the corpus cavernosum and tunica albuginea and successfully reconstructed the biomimetic dynamic neophallus. STRENGTHS AND LIMITATIONS This is to our knowledge the first report of biomimetic dynamic phalloplasty using the bilateral pedicled gracilis muscle combined with the fascia lata to mimic the complex structure of the phallus and enable the achievement of erection. However, due to the small number of patients included in this study, the data have no statistical significance. More cases are needed to obtain conclusive data and examine the long-term clinical effects of this procedure. CONCLUSION Using novel methods for phalloplasty, we successfully maintained the patient's ability to obtain sufficient hardness and subjective controllability without the use of implants, and the preliminary clinical results are encouraging.

Abstract
Gender-affirming hormone therapy (GAHT) is the most frequent treatment offered to gender-incongruent individuals, which reduces dysphoria. The goal of therapy among gender-incongruent individuals seeking gender affirmation as male is to change their secondary sex characteristics to affect masculine physical appearances. GAHT greatly improves mental health and quality of life among gender incongruent individuals. India-specific guideline for appropriate care for gender-incongruent individuals is almost absent. This document is intended to assist endocrinologists and other healthcare professionals interested in gender incongruity for individuals seeking gender affirmation as male. A safe and effective GAHT regimen aims to effect masculinising physical features without adverse effects. In this document, we offer suggestions based on an in-depth review of national and international guidelines, recently available evidence and collegial meetings with expert Indian clinicians working in this field. Clinicians represented in our expert panel have developed expertise due to the volume of gender incongruent individuals they manage. This consensus statement provides protocols for the hormone prescribing physicians relating to diagnosis, baseline evaluation and counselling, prescription planning for masculinising hormone therapy, choice of therapy, targets for monitoring masculinising hormone therapy, clinical and biochemical monitoring, recommending sex affirmation surgery and peri-operative hormone therapy. The recommendations made in this document are not rigid guidelines, and the hormone-prescribing physicians are encouraged to modify the suggested protocol to address emerging issues.

Abstract
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.

Abstract
Introduction The autologous skin flap is still the mainstream method for penile reconstruction, but it is very difficult to reconstruct a functional corpus cavernosum. Tissue engineering provides a new idea aiming to restore the damaged or absent corpus cavernosum. Aim To assess the feasibility of constructing the tissue-engineered corpus cavernosum with autologous adipose stem cells in a rabbit model. Methods A total of 30 New Zealand male white rabbits. Among them, 20 rabbits were used to obtain the original corpus cavernosum which were used to prepare the acellular corporal scaffolds (ACSs). The others were used for acquiring autologous adipose stem cells (ADSCs) and constructing tissue-engineered corpus cavernosum in vivo. Outcome ACSs were obtained from rabbit penile tissues through an established decellularization procedure. Rabbit autologous ADSCs as seed cells were harvested and expanded. The ADSCs seeded and unseeded ACSs were implanted back into the intramuscular and subcutaneous site in vivo, and the tissue-engineered corpus cavernosum was harvested and analyzed with gross morphology, histological staining, and real-time PCR assay after 1, 3, and 6 months. Results ACSs were successfully prepared. The cell non-cytotoxicity and integrity of micro-architecture of ACSs was confirmed in vitro. The cell-seeded scaffold in the intramuscular group was considered as the better strategy for constructing the tissue-engineered corpus cavernosum compared with the other groups. Some α-SMA and CD31 positive cells were detected and identified by immunofluorescent staining and real-time PCR assay in the tissue-engineered corpus cavernosum. Clinical Translation This study provides a new method for constructing the tissue-engineered corpus cavernosum. Strengths and Limitations First, it is urgent to improve the transformation rate of the endothelial cells and smooth muscle cells from ADSCs. Second, the scaffold harvested in this study was not a complete matrix. Third, further study is needed to explore the potential mechanism of which scaffolds are more suitable for living in intramuscular rather than subcutaneous environment. Conclusion In this study, we used the autologous ADSCs as seed cells, the acellular corpus cavernosum as scaffolds, and implanted the grafts back into the rabbit model to preliminarily construct the tissue-engineered corpus cavernosum. This study would provide help for further development in tissue-engineered corpus cavernosum. Cao Z, Liu L, Jiao H, et al.

Abstract
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.

Abstract
The pedicled flap has been a mainstay of soft tissue reconstruction since the earliest days of plastic surgery. Advances in surgical technology and skill have led to an erosion in the use of pedicled flaps in favor of increasingly popular free tissue transfers. Still, regional flaps without microvascular anastomosis remain a valuable reconstructive tool. Although still requiring microsurgical skills, these flaps are of particular benefit in patients with few or poor quality recipient vessels, in those who cannot tolerate antiplatelet therapy, and in those who cannot tolerate the often-extended anesthesia time necessitated by microvascular anastomosis. Furthermore, pedicled flaps may significantly reduce total cost of a reconstruction procedure with similar outcomes. In this case series, we report challenging scenarios where microsurgical approaches may have been typical choices but were instead reconstructed by pedicled options with desired outcomes. Difficult soft tissue defects were successfully reconstructed with a variety of pedicled flaps. Soft tissue transfers to the abdomen, flank, shoulder, and back are presented. None of the reconstructions required microvascular anastomosis.

Abstract
Male infertility is an increasing and serious medical concern, though the mechanism remains poorly understood. Impaired male reproductive function affects approximately half of infertile couples worldwide. Multiple factors related to the environment, genetics, age, and comorbidities have been associated with impaired sperm function. Present-day clinicians rely primarily on standard semen analysis to diagnose male reproductive potential and develop treatment strategies. To address sperm quality assessment bias and enhance analysis accuracy, the World Health Organization (WHO) has recommended standardized sperm testing; however, conventional diagnostic and therapeutic options for male infertility, including physical examination and semen standard analysis, remain ineffective in relieving the associated social burden. Instead, assisted reproductive techniques are becoming the primary therapeutic approach. In the post-genomic era, multiomics technologies that deeply interrogate the genome, transcriptome, proteome, and/or the epigenome, even at single-cell level, besides the breakthroughs in robotic surgery, stem cell therapy, and big data, offer promises towards solving semen quality deterioration and male factor infertility. This review highlights the complex etiology of male infertility, especially the roles of lifestyle and environmental factors, and discusses advanced technologies/methodologies used in characterizing its pathophysiology. A comprehensive combination of these innovative approaches in a global and multi-centric setting and fulfilling the suitable ethical consent could ensure optimal reproductive and developmental outcomes. These combinatorial approaches should allow for the development of diagnostic markers, molecular stratification classes, and personalized treatment strategies. Since lifestyle choices and environmental factors influence male fertility, their integration in any comprehensive approach is required for safe, proactive, cost-effective, and noninvasive precision male infertility theranostics that are affordable, accessible, and facilitate couples realizing their procreation dream.

Abstract
OBJECTIVE Neophallic urethroplasty remains a significant challenge in penile reconstruction. Currently, there is no ideal recognized method. Through this article, we aimed to share our experiences of urethral reconstruction in the pedicled anterolateral thigh flap penile reconstruction using modified techniques and alternative flaps. METHODS In this single-center study from 2010 to 2020, 49 patients underwent penile reconstruction with a pedicled anterolateral thigh flap; 17 patients had a micropenis, 3 had iatrogenic defects, and 29 had penile defects after trauma. Different urethroplasty methods, complications, and revision methods were separately described. The tube-in-tube technique was used in 6 cases; the superficial iliac circumflex artery perforator (SCIAP) flap and pudendal-thigh flap were used in 26 and 11 cases, respectively, and the pedicled scrotal flap was used in 6 cases. Revision urethroplasty due to postoperative necrosis (n = 3), stricture (n = 8), and fistula (n = 2) were performed in 13 cases. RESULTS The urethral complications (flap necrosis, urinary fistula, and stricture) were as follows: tube-in-tube, 66.7%; SCIAP flap, 46.2%; pudendal-thigh flap, 38.5%; and scrotal septum flap, 50%. After revision procedures, all patients could urinate while standing. CONCLUSIONS The characteristics and requirements of patients should be considered before designing a surgical plan. The tube-in-tube technique is the first choice for reconstructing the penis and urethra in a single stage for thinner patients. For other patients, a different flap can be used as a substitute for urethral reconstruction. The SCIAP, pudendal-thigh, and pedicled scrotal flaps can be used to reconstruct the urethra. The tubed SCIAP flap and pudendal-thigh flap are reliable, simple, and suitable for revision urethroplasty.

Abstract
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.

Abstract
Given the multifunctional role of the penis in daily life, penile loss can be a physically and emotionally devastating injury. Options to restore penile loss have traditionally relied on autogenous free flap, local flaps, and skin grafts. These techniques provide satisfactory outcomes but carry high rates of urologic and prosthesis-related complications. Vascularized composite allotransplantation may offer a novel solution for these patients through reconstruction with true penile tissue. Still, penile transplants pose ethical, logistical, and psychosocial challenges. These obstacles are made more complex by the limited cases detailed in published literature. A review of the literature was conducted to assay current practices for penile reconstruction. Most modern complex penile reconstructions utilize autogenous pedicled or free tissue flaps, which may be harvested from a variety of donor sites. A total of five penile transplants have been described in the literature. Of these, four report satisfactory outcomes. The advent of genital allotransplantation has recently broadened the landscape of treatment for penile loss. Reconstruction using true penile tissue through vascularized penile allotransplantation has the possibility to engender increased penile function, sensation, and overall quality of life.

Abstract
Reconstruction of tissue defects resulting from high-voltage injuries remains a serious issue in plastic surgery. For many years it has been solved by applying autologous reconstruction with rotated and revascularized flaps. We present a series outlining reconstructive practices in treatment of patients with high-voltage “uromanual” injuries. These types of injuries include a group of upper extremities and genitoperineal high-voltage trauma due to urination on an electrical source, which are rarely discussed in the literature. This study aimed to describe the algorithm of perioperative care and surgical treatment in patients with high-voltage uromanual trauma. Three male patients (mean age 26.3 years, range: 20–35 years) with traumatic injury of the genital area and the upper extremities due to high-voltage injury underwent reconstruction with a one-stage repair of defects. In one patient, the defect of the left upper extremity was eliminated by microsurgical autotransplantation of musculocutaneous thoracodorsal artery perforator flap. The genitoperineal region was repaired using rotated scrotal flaps. In two other cases, phalloplasty with a revascularized myocutaneous thoracodorsal artery perforator flap was followed by urethroplasty with a prefabricated radial forearm free flap. Hand deformities were eliminated using split-thickness skin autografts. All flaps survived. No complications were observed in the autograft harvesting areas. All cases showed good aesthetic and functional postoperative outcomes. Management of uromanual injuries should include one-stage reconstruction of upper extremities and genitoperineal defects for restoration of satisfying functional and aesthetic components crucial for patient’s quality of life and socialization.

Abstract
BACKGROUND In phalloplasty, there is a lack of standardized follow-up examinations of motor function and strength after harvesting oversized radial forearm free flaps (RFFF). METHODS We evaluated the donor site of 20 transmen after phalloplasty, using a multimodal, standardized approach, assessing the following parameters: opposition of the thumb, composite range of motion of the finger joints, grip strength, mobility of the wrist, lesion of the superficial branch of the radial nerve, the dorsal branch of the ulnar nerve, the sensation of pain, and cold intolerance. The contralateral, nonoperated forearm was used as a control. RESULTS No impairment of the mobility of the thumb (Kapandji score median 10, range 5-10) or fingers (all fingers at both sides pulp-to-palm 0 cm, nail-to-table 0 cm) were detected. Grip strength (median 36,3kg, p=0.629) and wrist extension (62.5°vs.70°, p=0.357), flexion (70°vs.70°, p=0.535), pronation (90°vs.90°), supination (90°vs.90°), radial (30°vs.30°, p=0.195), and ulnar deviation (40°vs.50°, p=0.125) did not statistically differ between donor and control hand. Injury of the dorsal branch of the ulnar nerve was uncommon (0% hypoesthesia, 10% positive Tinel's sign). We did not observe any persistent pain of the donor forearm (NRS median 0, range 0-9). We did observe irritation of the superficial branch of the radial nerve (hypoesthesia 40%, neuroma 45%). CONCLUSION The harvest of an oversized RFFF for phalloplasty does not cause any significant difference in motor function or strength between the donor and nonoperated hand. A potential risk of injuring the radial nerve branch is to be avoided. An aesthetic impairment could be addressed in future studies.

Abstract
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.

Abstract
BACKGROUND The clitorophallus, or glans, is a critical structure in sexual development and plays an important role in how gender is conceptualized across the life span. This can be seen in both the evaluation and treatment of intersex individuals and the use of gender-affirming masculinizing therapies to help those born with a clitoris (small clitorophallus with separate urethra) enlarge or alter the function of that structure. OBJECTIVES To review the role of testosterone in clitorophallus development from embryo to adulthood, including how exogenous testosterone is used to stimulate clitorophallus enlargement in masculinizing gender-affirming therapy. MATERIALS AND METHODS Relevant English-language literature was identified and evaluated for data regarding clitorophallus development in endosex and intersex individuals and the utilization of hormonal and surgical masculinizing therapies on the clitorophallus. Studies included evaluated the spectrum of terms regarding the clitorophallus (genital tubercle, clitoris, micropenis, penis). RESULTS Endogenous testosterone, and its more active metabolite dihydrotestosterone, plays an important role in the development of the genital tubercle into the clitorophallus, primarily during the prenatal and early postnatal periods and then again during puberty. Androgens contribute to not only growth but also the inclusion of a urethra on the ventral aspect. Exogenous testosterone can be used to enlarge the small clitorophallus (clitoris or micropenis) as part of both intersex and gender-affirming care (in transmasculine patients, up to 2 cm of additional growth). Where testosterone is insufficient to provide the degree of masculinization desired, surgical options including phalloplasty and metoidioplasty are available. DISCUSSION AND CONCLUSION Endogenous testosterone plays an important role in clitorophallus development, and there are circumstances where exogenous testosterone may be useful for masculinization. Surgical options may also help some patients reach their personal goals. As masculinizing gender-affirming care advances, the options available for clitorophallus modifications will likely continue to expand and improve.

Abstract
INTRODUCTION Fashioning a functioning neo urethra in a boy with aphallia is one of the unsolved problems in this condition. AIM We present our technique and outcome of operative exposure and neo urethral construction in four aphallic boys. MATERIALS AND METHODS Retrospective study of the records of four aphallic boys operated in the period 2015-2019 was undertaken. The demographics, presentation, operative procedure, current follow up and voiding outcome was noted. RESULTS The neo phallus was constructed by the De Castro technique in four aphallic boys aged 1-8 years. Pre operative assessment revealed bladder outflow obstruction in two and urinary incontinence in one boy. The operative exposure afforded after reflection of the De Castro flap was utilized in doing a limited pubic symphysiectomy. This exposed the bladder neck, urethra and the urethral termination into the ano rectum. The healthy native urethra was isolated by disconnecting it from its ano rectal termination and a neo urethra constructed from a segment of proximal sigmoid colon by its reconfiguration into a Monti type tube. The neo urethra was then anastomosed to the native urethra and laid within the bed of the De Castro flap so as to reach the neo phallic termination. The De Castro flap was then tabularized over the neo urethra to form the new phallus. Appendicular or ileal Monti Mitrofanoff was also added to the reconstruction. Three boys are voiding well. One boy had a partial bladder outflow obstruction resulting from operative correction of incontinence and is dry on intermittent catheterization. Follow up was for 1-4 years and upper tracts are stable or improved. CONCLUSION We describe the transpubic approach to the construction of a reliable neo urethra in the form of a Monti tube from the sigmoid colon in four boys with aphallia. We believe this to be a useful addition to the De Castro procedure for neo phallic construction.

Abstract
BACKGROUND Males born with bladder exstrophy-epispadias complex generally have a shorter phallus, split corpora with dorsal curvature, and a scarred and flattened glans, so substitution phalloplasty is often required. AIM The aim of this study was to review the techniques, complications, and outcomes of substitution phalloplasty in bladder exstrophy-epispadias complex patients to determine the ideal surgical procedure and gauge the risks and benefits for the patient. METHODS A systematic review of the literature was performed using PubMed/MEDLINE and the Cochrane Library with the following terms: ("phalloplasty"); (("epispadias") OR ("bladder exstrophy") OR ("cloacal exstrophy")). We included only full-text articles reporting data about techniques and outcomes of substitution phalloplasty in patients with bladder exstrophy-epispadias complex. OUTCOMES To determine whether patients with bladder exstrophy-epispadias complex might benefit from substitution phalloplasty. RESULTS We selected 7 studies involving 47 patients. All the studies were characterized by a low level of evidence and a heterogeneous approach during treatment and outcome assessment. The free radial forearm flap was the most commonly performed technique (89%) with an overall complication rate of 15%. Urethroplasty was performed in 22 of 47 (47%) patients, and in most cases (20/22) a "tube-within-the-tube" technique was performed simultaneously with the phalloplasty (20/47). Urethroplasty complications were recorded in 12 of 22 (54%) patients with 6 fistulae and 6 stenoses. A penile prosthesis was implanted in 32 of 47 (68%) patients and complications occurred in 8 of 32 (25%) patients with 6 erosion. Aesthetic, sexual, and psychological outcomes were satisfactory, but none of the studies used validated instruments for the final assessment. CLINICAL IMPLICATIONS It was not possible to formulate any recommendations based on a high level of evidence regarding substitution phalloplasty in patients with bladder exstrophy-epispadias complex. STRENGTH & LIMITATION To our knowledge, this is the first review to address bladder exstrophy-epispadias complex patients only. The limitations are mainly represented by the small number of cases because of the rarity of this disease and by the fact that no studies used validated instruments. CONCLUSION Substitution phalloplasty in patients with bladder exstrophy-epispadias complex can achieve good functional, aesthetic, psychological, and sexual outcomes. It requires multiple procedures and carries a high complication rate. Multicentric studies including the assessment of patients by means of a validated questionnaire which investigates both sexual function and psychosexual satisfaction are required.

Abstract
The success of free vascularized fibular bone graft (FVFBG) has accelerated the osteo reconstruction which results from trauma, resection of a tumor or an infectious bone segment, or correction of congenital deformity. But the complication behind should not be overlooked. The failure could necessitate a second surgery, which prolong the rehabilitation period and produce further health cost. Worst, the patients may suffer a permanent impaired ankle function, or a sustained morpho-functional loss on reconstructive area which are hard to save. To provide an overview of the complication related to reconstruction by FVFBG, a narrative review is conducted to identify the complications including their types and rates, the contributing factors, the approaches to measure and the techniques to avoid. Methodologically, by quick research on Pubmed and abstract reading of reviews, we characterize five reconstructive areas where FVFBG were most frequently applied: extremities, mandible, spine, osteonecrosis of femoral head, and penile. Following, the complications on different reconstructive areas are retrieved, studied and presented in five (or more specifically, six) separate sections. By the way, meaningful difference between FVFBG and other bone flap was presented in a few words if necessary. Donor-site morbidities were studied and summarized as a whole. In these literatures, the evidences documented on limb and mandibular reconstruction have the fullest detail, followed by the spine and lastly the penile. In conclusion, FVFBG, though a mature technique, needs further deep and comprehensive study and maybe device-based assistance to achieve better reconstructive effect and minimize donor-site damage.

Abstract
BACKGROUND The increasing prevalence of gender dysphoria necessitates an evaluation of the literature of phalloplasty techniques for female to male transgender individuals. OBJECTIVE The following article provides an overview of the current surgical concepts and complications of phalloplasty, associated urethrogenitoplasty and the implantation of prostheses in phalloplasty. MATERIAL AND METHODS Current international reviews and original publications from 2010 to 2020 were reviewed and correlated with our referral center experience with more than 350 female to male transgender patients over the last 25 years. RESULTS Free radial forearm flap phalloplasty is the most widely used technique, followed by an anterolateral thigh flap (ALT flap) and pedicled or microsurgical transplantation. Hydraulic multicomponent prostheses are given preference and supplementary surgical techniques, such as scrotoplasty and glans sculpturing can make sense or be necessary. The complication rates after phalloplasty and after insertion of penile prostheses are substantial. Nevertheless, the overall patient reported satisfaction rate in the majority of studies is often over 80%. CONCLUSION Due to the increasing prevalence of gender dysphoria there is currently a need for interdisciplinary referral centers for gender reassignment surgery. A certain standardization of surgical techniques and timing would be desirable but a review of the current literature shows a high heterogeneity so that this cannot be derived from the currently available literature. It is hoped that the recently founded S2K guideline committee on operative treatment of gender dysphoria under the auspices of the German Society for Urology and the Society for Plastic and Reconstructive Surgery can report an initial collection of experiences in 2021.

Abstract
BACKGROUND The goals of penile reconstruction and phalloplasty include aesthetics as natural as possible and the ability of patients to void while standing and to have sexual intercourse. This article presents two more rare indications and techniques, the phalloplasty using free radial forearm flapin case of intersexuality and after penectomy due to penis carcinoma. PATIENTS AND METHODS In transsexual individuals numerous phalloplasties in Gottlieb and Levine`s technique, by means phalloplasty of free radial forearm-flap of the non-dominant forearm, were performed in our department over the last few years. However, this technique also has its significance for phalloplasty in non-transgender persons.Two patients are considered in detail with regard to indication and surgical technique and were followed up in a multimodal setting.Patient 1 is genetically male, thirty-five years old with a micropenis in the case of pseudohermaphroditism masculine and androgen resistance.Patient 2 is a fifty-one-year old genetically male and as a result of a penis carcinoma his penis had to be amputated at the level of penis root. After absence of recurrence for 1,5 years, the penile reconstruction took place after complete resection of the remaining residual penile stump and corpora cavernosa. Both patients underwent multimodal follow-up 15 months postoperatively with regard to phalloplasty sensors and donor-site restrictions. RESULTS An aesthetic and functional acceptable result could be obtained for both patients. Both patients are able to void while standing. The multimodal follow-up 15 months postoperatively revealed relevant differences in the sensory findings of both patients, which are due to the different anatomy of reinnervation. CONCLUSION In microsurgical experienced departments, the technique of A. radialis phalloplasty can also be used successfully in more rare indications, as shown here, a satisfying result can be achieved in terms of function and aesthetics. The complications shown here do not differ from those using phalloplasty in transgender persons.

Abstract
Penile amputation is a rare deformity mostly resulting from self-mutilation, felonious assault, or accidental trauma, and penile reconstruction or phalloplasty is necessary when microreplantation cannot be performed. Here we report a rare case of a 42-year-old man with traumatic penile amputation and describe surgical techniques for partial penile reconstruction by using a novel innervated and vascularized radial thenar flap free grafting method. Excellent cosmetic and functional results were reported with no severe complications of dysuria, urethral stricture, and urinary fistula were observed during the 23 months of postoperative follow-up time. It is believed that innervated and vascularized radial thenar flap free grafting is an acceptable treatment option for patients with traumatic penile amputation.

Abstract
Circumcision is regarded as one of the most common procedures in pediatrics. We present a case of a newborn, who has undergone circumcision using monopolar electrocautery. He admitted to the hospital with glans necrosis and was treated with antibiotics and surgical debridement. Four months later, phalloplasty was performed for the newborn using scrotal flap. The result is satisfactory, and the penis is esthetically acceptable with effective urination. Our case suggests the use of scrotal flap for penile reconstruction due to feasibility of procedure and anatomic privilege. It would also support usage of bipolar electrocautery for circumcision to avoid possible unwanted complications of monopolar electrocautery.

The Buschke–Löwenstein tumor comes from the confluence of multiple condyloma acuminata and is clinically manifested by warty, exophytic, ulcerated lesions, with aggressive behavior, rapid growth, invasion and destruction of adjacent structures.
Case presentation
A 57-year-old man with type II diabetes mellitus, high blood pressure and a history of high-risk sexual behavior with multiple partners was evaluated in the urology department for multiple penile lesions of verrucous appearance and fetid odor of 10 months of evolution. Biopsy of the lesion was performed revealing a giant condyloma acuminatum.
Conclusions
Radical surgical excision with wide surgical margins remains the first line of treatment. Close follow-up of these patients is crucial given the complexity and tumor recurrence.

Abstract
Penile wounds after traumatic and surgical amputation require reconstruction in the form of autologous tissue transfers. However, currently used techniques are associated with high infection rates, implant erosion and donor site morbidity. The use of tissue-engineered neocorpora provides an alternative treatment option. Contemporary tissue-engineering strategies enable the seeding of a biomaterial scaffold and subsequent implantation to construct a neocorpus. Tissue engineering of penile tissue should focus on two main strategies: first, correcting the volume deficit for structural integrity in order to enable urinary voiding in the standing position and second, achieving erectile function for sexual activity. The functional outcomes of the neocorpus can be addressed by optimizing the use of stem cells and scaffolds, or alternatively, the use of gene therapy. Current research in penile tissue engineering is largely restricted to rodent and rabbit models, but the use of larger animal models should be considered as a better representation of the anatomical and physiological function in humans. The development of a cell-seeded scaffold to achieve and maintain erection continues to be a considerable challenge in humans. However, advances in penile tissue engineering show great promise and, in combination with gene therapy and surgical techniques, have the potential to substantially improve patient outcomes.

Abstract
Phalloplasty can be a challenging plastic surgery procedure associated with complications and unsatisfactory results. Phalloplasty has become an important procedure in the setting of trauma, partial or complete excision of the penis, and gender affirmation. Advances in microsurgery has expanded penile reconstruction through free tissue transfer techniques which include the radial forearm free flap, fibular osteocutaneous flap, anterolateral thigh flap, latissimus dorsi flap, scapular flap, and abdominal flaps. Each procedure has advantages and disadvantages; most of the procedures achieve adequate cosmetic results with high patient satisfaction. Most of the surgical complications are related to the reconstruction of the urethra or creating rigidity for intercourse. The main goals of reconstruction are to create a cosmetically appealing phallus with satisfactory sexual function.
