The Pedicled Anterolateral Thigh Phalloplasty

Revision Phalloplasty: Evaluation, Algorithms, and Techniques for Salvage after Major Complications

BACKGROUND

Phalloplasty is among the most complex and technically demanding reconstructive procedures. As a larger pool of surgeons perform this difficult procedure, more patients will present with major complications. There are few published data on the comprehensive evaluation and management of these patients, particularly those needing correction of multiple ongoing complications, which may require consideration of starting over with a new microsurgical procedure versus salvage of the existing flap.

METHODS

A literature review on complications of phalloplasty was conducted in combination with drawing upon the experience of 2 high-volume phalloplasty teams (Johns Hopkins/Harvard and GU Recon Clinic/Buncke Clinic) in treating patients with severe postsurgical issues. The purpose was to analyze critical factors and develop algorithms for secondary revision.

RESULTS

Common complications of phalloplasty include urethral strictures and fistulas, diverticula, excess bulk, phalloplasty malposition, hypertrophic or keloidal scarring, and partial or total flap loss. In severe cases, local flaps or free flaps may be required for reconstruction. The decision to revise the existing neophallus or start over with a new flap for phalloplasty is particularly critical. Multidisciplinary team collaboration is essential to develop comprehensive plans that will resolve multiple concomitant problems while meeting patient goals for a functional and aesthetic neophallus.

CONCLUSIONS

Preserving the original flap for phalloplasty is ideal when feasible. Additional local or free flaps are sometimes necessary in situations of significant tissue loss. In severe cases, complete redo phalloplasty is required. The algorithms proposed provide a conceptual framework to guide surgeons in analyzing and managing severe complications after phalloplasty.

[New S2k guideline "Surgical techniques for gender incongruence"]

BACKGROUND

Various techniques for the surgical treatment of gender incongruence (GI) have been available for years. The spectrum is broad and covers various specialties. In recent years, there has been an increase in the number of clinics offering body-modifying procedures. This has led to a considerable variation in methods in some cases. Although the topic has recently found its way more and more into teaching and the relevant specialist literature, there are still no evidence-based recommendations on the various techniques.

AIM

A compendium of established surgical techniques was to be compiled, containing recommendations on indication, performance and aftercare as well as complication management and subjecting them to a consensus-based evaluation.

MATERIALS AND METHODS

In accordance with "Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften" (AWMF) regulations, the guideline was developed at level S2k, i.e., it is consensus based. The guideline group was founded in February 2019 in a formal constituent meeting. A total of 14 medical societies and 2 interest groups were recruited for the guideline work. In the end, two consensus meetings were held, which was due to the large number of recommendations and background texts to be adopted.

RESULTS

The guideline focuses on the choice and applicability of surgical techniques as well as the wishes of those seeking treatment and protection of fertility. There is a wide variety of methods and treatment goals for each individual. Taking into account medical standards, recommendations, and contraindications, an optimal result that minimizes individual suffering can be achieved together with the person seeking treatment.

CONCLUSION

The content of the guideline represents a unique compendium of surgical methods, recommendations for the selection of procedures, and common indications in the field of body-modifying surgery for gender incongruence.

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.

The pedicled gracilis muscle combined with the fascia lata: a preliminary clinical study of a new biomimetic dynamic phalloplasty method

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.

Pedicled superficial circumflex iliac artery perforator flap for male genital reconstruction: A case series

BACKGROUND

Different issues may cause defects in the genital region, including urological, infective, oncological and genetic problems which often lead to significant defects. This is a very delicate region and a successful coverage requires a thin, pliable and reliable solution. In this setting the SCIP flap might be an outstanding procedure. Despite being a well-known solution in the groin region, its employment for genital reconstructions is still poorly described. For this reason, we gather our experience with this procedure showing the efficacy of the SCIP flap in this specific region.

PATIENTS AND METHODS

In the present case series we included 6 male patients who received a soft tissue defect reconstruction by means of pedicled SCIP flap over the last year. The average age was 53.6 years old (range 34-79 years). Among them, 5 patients received a surgical excision because of severe acne (2 cases), Fournier's gangrene (2 cases), or scrotal squamous cell carcinoma (1 case). In 1 case the cause of the missing volume was testicle agenesis and the reconstruction was performed for cosmetic purposes. Size of the defects ranged from 7 cm × 4 cm to 20 cm × 6 cm. Elliptical shaped flaps were designed either mono- or bilaterally according to the need. All the flaps were supplied by the superficial branch of the SCIA. The range of rotation varied between 150° and 180° in order to reach the affected area.

RESULTS

The flaps' dimension ranged from 8 cm × 4 cm to 20 cm × 6 cm. All the patients were successfully treated. In 1 case we encountered a small wound dehiscence, which was managed conservatively. The mean follow-up was 9.5 months (range 6-12 months). Good cosmetic result was achieved in all cases and no urinary or sexual dysfunctions were reported.

CONCLUSIONS

The pedicle SCIP flap represents a reliable solution for genital and inguinal defects reconstructions. Its versatility can be exploited throughout the region providing very good quality tissues that can be used for the most disparate situations.

Urethra Reconstruction and Revision Urethroplasty in Pedicled Anterolateral Thigh Flap Penile Reconstruction

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.

Salvage of a Near-Total Penile Amputation following Urinary Fistulization and Carbapenemase-Producing Klebsiella pneumoniae Infection with a Composite ALT Flap and Vascularized Fascia Lata

Reconstruction of complex penile defects is always challenging, as some defects are not possible to reconstruct with skin or mucosa grafts, and even local flaps may be precluded in complex wounds. We present a case of a 63-year-old otherwise healthy man, who underwent transurethral resection of the prostate for benign prostatic hyperplasia. After the procedure, he developed panurethral necrosis with consequent stricture. Three urethroplasties for reconstruction of the bulbar and distal urethra using buccal mucosa grafts, a preputial flap, and penile skin were performed by urology team in different institutions, but serious urinary fistulization and carbapenemase-producing Klebsiella pneumoniae (KPC) infection translated in a chronic wound, urethra necrosis, and near-total penile amputation. A composite anterolateral thigh flap and vascularized fascia lata were used with success together with a perineal urethroplasty in different stages, improving the ischemic wound condition. The extended segment of fascia lata was used for Buck's fascia replacement and circumferential reinforcement to cover the erectile bodies of the penis. The postoperative period was uneventful and after 12 months, there were no signs of recurrence or wound dehiscence. He was able and easily adapted to void in a seated position through the perineal urethrostomy that was made. To the best of our knowledge, this procedure has not been reported previously as a salvage procedure in a fistulizated and KPC infected penis, but it may be considered to avoid penile amputation in chronic infected and intractable wounds.

Partial Flap Loss in Gender Affirming Phalloplasty

BACKGROUND

 Flaps used in phalloplasty are larger than described for other indications, with a design that is tubularized up to two times. While the incidence of partial flap loss (PFL) is well described, current literature lacks granularity comparing donor sites and techniques with minimal discussion of etiology and management. The purpose of this study was to review our experience with PFL in phalloplasty.

METHODS

 This was a retrospective cohort study of patients who underwent phalloplasty by a single surgeon at a single institution between 2016 and 2020. PFL was defined as any patient requiring sharp excision of necrotic tissue and reconstruction. Patient variables (demographics, body mass index, American Society of Anesthesiologists physical status classification, comorbidities), flap variables (donor site, design, dimensions, perforator number) and intraoperative variables (use of vasopressors, intraoperative fluid volume) were collected.

RESULTS

 Of 76 phalloplasties, 6 patients suffered PFL (7.9%). 5/6 patients were radial forearm free flap tube-within-tube (TWT) and 1/5 patients were pedicled anterolateral thigh TWT. 4/6 cases involved the shaft only and were treated with excision ± Integra and full-thickness skin grafting. 2 cases of PFL involved the urethral extension requiring excision of the necrotic segment.

CONCLUSION

 PFL occurred in 7.9% of cases and was solely found in the TWT cohort. The majority of cases involved the shaft, sparing the urethral segment. Cases in the acute postoperative period appeared to be related to macrovascular venous congestion, while cases in the subacute period appeared to be due to microvascular arterial ischemia.

Planned and Unplanned Delayed Anterolateral Thigh Flap Phalloplasty

Background:

Pedicled anterolateral thigh (ALT) flap phalloplasty can be limited by inadequate perfusion. Vascular delay increases perfusion, as delay causes blood vessel formation by limiting the blood supply available to a flap before transfer. We hypothesized that delayed ALT flap phalloplasty would decrease rates of partial flap or phallus loss and other postoperative complications when compared with previously reported complication rates of undelayed single-stage ALT phalloplasty in our practice.

Methods:

A retrospective medical record review was performed on all phalloplasty patients in our practice between January 2016 and September 2019. We found those patients who had completed delayed ALT flap phalloplasty with at least 6 months of delay and 12 months of follow-up. For these patients, we recorded postoperative complications, simultaneous surgeries, subsequent surgeries, and demographic characteristics.

Results:

Five female-to-male transsexuals underwent delayed ALT flap phalloplasty (two were unplanned procedures, three were planned). Planned delay: The average time between Stage 1 and Stage 2 was 6.5 months. Complications for the planned delay cohort were as follows: partial loss of the neophallus not requiring repair (33%), urethral stricture requiring surgical repair (33%). Unplanned delay: The average time between Stage 1 and Stage 2 was 9.1 months. The following complication was seen in the unplanned delay cohort: urethral stricture requiring surgical repair (50%).

Conclusions:

Vascular delay of ALT flap phalloplasty is a successful emergency salvage procedure. Planned delay of ALT flaps provided similar results compared with those previously reported by our practice with standard single-stage approach.

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.

Narrative review of the history of microsurgery in urological practice

The clinical need for magnified visualization during surgery spurred the evolution of microscope and microsuture technology. Innovative surgeons across various surgical specialties recognized the importance of utilizing and advancing these technologies. Operative microscopy allows human dexterity to perform beyond direct visual limitations. Microsurgery started in otolaryngology and ophthalmology, became popular in reconstruction and transplantation, and was then adopted in urology. Microsurgery in urology involves renal and penile revascularization, penile transplantation and free flap phalloplasty, testicular autotransplantation, reproductive tract reconstruction of the vas deferens and epididymis, varicocele repair, and sperm retrieval. By examining the peer reviewed and lay literature, this review discusses the history of microsurgery and its subsequent development as a subspecialty in urology.

Suprapubic phalloplasty in transmen: surgical results and critical review

This article presents the surgical outcomes of a consecutive series of 71 transmen undergoing pre-expanded suprapubic phalloplasty (SPP) in a specialized center. The median [IQR] duration to finalize this three-stage phalloplasty procedure was 7 months [6-7]. Median [IQR] follow-up was 39.4 months [19.7-81.2]. Among those included, 25 (35.2%) had a urethroplasty, and 40 (56.3%) a penile prosthesis as additional procedures. Complications were the result of disorders of wound healing (dehiscence, infection, partial necrosis) or tissue expander (migration, infection). Sixty patients (84.5%) experienced at least one complication during the phalloplasty procedure, mostly minor complications Clavien < IIIa (81.8%). Among these, 16 (22.5%) underwent at least one reintervention, 2 of whom underwent two reinterventions (18 reinterventions in total for Clavien ≥ IIIa complication). There was no loss of phalloplasty. Among the wide variety of techniques developed for phalloplasty, the suprapubic technique seems to be a valuable option for transmen on the path to genital gender affirming surgery.

Infrapubic Insertion of Penile Implants in Transmen After Phalloplasty

OBJECTIVE

To describe the infrapubic approach to penile prosthesis insertion in transmen after phalloplasty.

MATERIALS AND METHODS

After verifying phalloplasty vascular pedicle anatomy and reliable micturition, patients may be considered for implant surgery. Specific modifications of the infrapubic approach to penile prosthesis insertion as well as individualization of commercially available implants are performed intraoperatively to help reduce the risk of postoperative complications.

RESULTS

In our single surgeon series (MLC) using the infrapubic approach with these specific implants after phalloplasty, 17/107 (16%) patients from October 2017 to November 2020 required revision surgery after mean follow-up of 79.8 weeks.

CONCLUSION

Our infrapubic prosthesis insertion after phalloplasty technique with modifications to commercially available implants may help reduce the risk of postoperative complications.

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.

Overview of surgical techniques in gender-affirming genital surgery

Gender related genitourinary surgeries are vitally important in the management of gender dysphoria. Vaginoplasty, metoidioplasty, phalloplasty and their associated surgeries help patients achieve their main goal of aligning their body and mind. These surgeries warrant careful adherence to reconstructive surgical principles as many patients can require corrective surgeries from complications that arise. Peri-operative assessment, the surgical techniques employed for vaginoplasty, phalloplasty, metoidioplasty, and their associated procedures are described. The general reconstructive principles for managing complications including urethroplasty to correct urethral bulging, vaginl stenosis, clitoroplasty and labiaplasty after primary vaginoplasty, and urethroplasty for strictures and fistulas, neophallus and neoscrotal reconstruction after phalloplasty are outlined as well.

Phalloplasty Following Penectomy for Fournier's Gangrene at a Tertiary Care Center

Treatment of Fournier's gangrene often requires extensive surgical debridements that can ultimately necessitate penile amputation. Reconstruction can be challenging as these patients tend to have medical comorbidities deeming them poor microsurgical candidates. Fournier's gangrene resulting in penectomy is an infrequent occurrence, and treatment with phalloplasty is rarely described in the literature. Herein, we present a case of a 60-year-old male with poorly controlled diabetes mellitus who developed Fournier's gangrene in July 2017. His treatment course included multiple surgical debridements without resolution, eventually necessitating a penectomy. The patient elected for surgical reconstruction and underwent a phalloplasty procedure utilizing a radial forearm free flap. This case demonstrates a rare case of Fournier's gangrene resulting in penectomy with a unique reconstruction utilizing a radial forearm free flap in a poor microsurgical candidate.
