RESUMEN
PURPOSE: Labia majora, the embryologic homologs of the scrotum, are ideal donor tissue for transgender scrotoplasty. The technique is detailed, and surgical outcomes are assessed for scrotoplasty using labia majora rotational advancement flaps. METHODS: We retrospectively reviewed the outcomes of phalloplasty patients who underwent either primary or secondary labia majora flap scrotoplasty and perineal reconstruction from October 1, 2017, to December 1, 2019. Bilateral elevation and rotational flap advancement from the posterior to anterior position formed a pouch-like scrotum. Perineal reconstruction involved multilayered closure with apposition of the inner thigh skin. RESULTS: The mean follow-up was 12.5 months (0.5-26 months). One hundred forty-seven scrotoplasties were performed. Of the 147 total scrotoplasty patients, 133 had labia majora flap scrotoplasty and perineal reconstruction with single-stage phalloplasty. Distal flap necrosis occurred in 6 patients (4.1%); 5 were ipsilateral to the groin dissection required for phalloplasty. Large (>1 cm diameter) perineoscrotal junction dehiscence occurred in 7 patients (4.7%). All wounds were managed conservatively except for 3 patients who developed urethrocutaneous fistulas at the perineoscrotal junction. All 3 patients required fistula repair. Two (1.4%) scrotal hematomas and 3 (2.0%) perineal hematomas were seen; all required operative intervention. CONCLUSIONS: Labia majora flap scrotoplasty via the bilateral rotational advancement technique and perineal reconstruction can be safely performed during phalloplasty. Minor wound complications are common and frequently heal with conservative management. Wounds that do not heal may be associated with urethral complications. Hematomas are rare but usually require operative intervention.

PURPOSE: Phalloplasty is a critical step in female-to-male (transmale) gender confirming genital surgery. We examined outcomes between transmales who underwent phalloplasty with vaginectomy and full-length urethroplasty using the anterolateral thigh pedicled flap or the radial forearm free flap. MATERIALS AND METHODS: We performed a single center, retrospective study of patients who underwent phalloplasty with vaginectomy and full-length urethroplasty using an anterolateral thigh pedicled flap or a radial forearm free flap from April 2013 to July 2016. All patients had at least 6 months of followup. Urethral and nonurethral complications were recorded. Complication rates were assessed using the OR of the anterolateral thigh pedicled flap and the radial forearm free flap groups. RESULTS: Of the 213 patients 149 and 64 underwent radial forearm free flap and anterolateral thigh pedicled flap phalloplasty, respectively. Patients with a radial forearm free flap had a significantly higher body mass index than those with an anterolateral thigh pedicled flap. The overall urethral complication rate for radial forearm free flap and anterolateral thigh pedicled flap phalloplasty was 31.5% and 32.8%, and the rate of partial or total neophallus loss was 3.4% and 7.8%, respectively. Patients in the pedicled flap cohort experienced significantly greater odds of urethral fistula (OR 2.50, p = 0.024), nonurethral complications (OR 2.38, p = 0.027) and phallus wound dehiscence (OR 5.03, p = 0.026). CONCLUSIONS: Anterolateral thigh pedicled flap phalloplasty was associated with overall greater odds of urethral and other complications at 6 months of followup. Our findings can help guide surgical decision making when selecting a flap for phalloplasty.

PURPOSE: We determined whether electrical stimulation of somatic afferent nerves in the foot could delay bladder filling sensations and increase bladder capacity in healthy humans without overactive bladder. MATERIALS AND METHODS: Eight subjects underwent 90-minute foot stimulation using skin surface electrodes connected to a transcutaneous electrical nerve stimulator. The electrodes were attached to the bottom of the foot. Subjects completed a 3-day voiding diary, during which foot stimulation was applied on day 2. Stimulation parameters were pulse frequency 5 Hz, rectangular waveform pulse width 0.2 milliseconds and intensity 2 to 6 times the minimal stimulation current necessary to induce toe twitch. Stimulation intensity was set by each subject to a maximal level without causing discomfort. Subjects were provided with 500 to 1,000 ml of water to drink during stimulation. RESULTS: Average ± SE volume per void was 350 ± 22 ml during the 24 hours before foot stimulation. This voided volume increased to a mean of 547 ± 52 ml for up to 5 hours after stimulation (p <0.01). Average voided volume returned to 363 ± 21 ml within 36 hours after stimulation. There were no adverse events. CONCLUSIONS: Foot stimulation can delay bladder filling sensations and significantly increase bladder capacity in healthy humans without overactive bladder. Although the study group was small, our results support moving forward with clinical trials of foot neuromodulation in patients with overactive bladder.

Renal lymphangiomatosis is a disease characterized by abnormal formation of perirenal lymphatic vessels that fail to communicate with other retroperitoneal lymphatics; as a result, perirenal lymphatics dilate and form cysts. While typically an asymptomatic incidental finding, renal lymphangiomatosis rarely presents as flank or abdominal pain, ascites, impaired renal function, hypertension, hematuria, or proteinuria. Here we present the first known case of renal lymphangiomatosis found to spontaneously resolve following cardiac transplantation.

INTRODUCTION: To evaluate the efficacy of transecting anastomotic urethroplasty (AU) and buccal mucosa graft (BMG) ventral onlay substitution urethroplasty (SU) in treating short bulbar urethral strictures. MATERIALS AND METHODS: Sixty patients underwent either AU or SU for bulbar strictures of similar length with follow up of at least 12 months. Follow up included clinical history, uroflowmetry, and ultrasound post-void residuals (PVR) performed every 4 months for the first year and yearly thereafter. RESULTS: Out of 131 patients with short bulbar strictures, 40 were treated with BMG onlay SU and 20 had AU. Median follow up in the SU group was 57 months (IQR 27-76) and 120 months (IQR 109-130) in the AU group. The median stricture length was 3 cm (IQR 2.5-3.0) in the SU group and 1.3 cm (IQR 1-2) in the AU group (p < 0.001). The 3 year freedom from intervention was 93% in the SU group, and 85% in the AU group (p = 0.72). CONCLUSIONS: BMG onlay ventral urethroplasty has similar success rates to anastomotic urethroplasty for short bulbar urethral strictures. Due to the relatively fewer complications reported after substitution urethroplasty with BMG, it should be considered the treatment of choice for short bulbar urethral strictures.

OBJECTIVE: To determine urethral outcomes of single-stage metoidioplasty and radial forearm free flap (RFFF) phalloplasty using the labia minora ring flap for urethral lengthening (UL). METHODS: A retrospective review was performed of patients undergoing single-stage metoidioplasty and RFFF phalloplasty utilizing the labia minora ring flap technique. The ring flap consists of endodermal labia minora tissue ventral to the clitoris and surrounding the vaginal introitus. During metoidioplasty, the ring flap accounts for the entirety of UL. During RFFF phalloplasty, the ring flap becomes the pars fixa (PF) urethra. The primary outcomes measured were rates of fistula, stricture, and surgical revision. RESULTS: Between November 2017 and August 2023, 311 patients underwent metoidioplasty or RFFF phalloplasty (mean follow-up 37 months). Of the 69 metoidioplasties, urethrocutaneous fistulas developed in 11 patients (16%); strictures occurred in 4 (6%). Of the 242 phalloplasty patients, there were 71 fistulas (29%), 56 of which resolved spontaneously. Strictures developed in 44 patients (18%). Twenty-five patients (10%) developed both a stricture and fistula. Surgical repair was required in 8/69 (12%) metoidioplasty patients and in 46/242 (19%) RFFF phalloplasty patients for an overall revision rate of 17%. CONCLUSION: UL during metoidioplasty or RFFF phalloplasty can be accomplished in a single stage using the labia minora ring flap with comparable surgical revision rates to previously described techniques. This approach can also be applied to other phalloplasty techniques. Many fistulas of the PF urethra resolve spontaneously. Higher urethral revision rates were seen in phalloplasty compared to metoidioplasty.

BACKGROUND: Phalloplasty is among the most complex and technically demanding reconstructive surgeries. As a larger pool of surgeons perform this difficult procedure, more patients will present with major complications. There is little published 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 two high-volume phalloplasty teams (Johns Hopkins/Brigham & Women's Hospital and GU Recon/Buncke Clinic) in treating patients with severe post-surgical issues. The purpose was to analyze critical factors and develop algorithms for secondary revision. RESULTS: Common complications of phalloplasty include urethral strictures and fistulae, diverticula, excess bulk, phalloplasty malposition, hypertrophic/keloidal scarring, and partial/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 following phalloplasty.
RESUMEN
OBJECTIVE: To describe our surgical technique and outcomes of glans augmentation with autologous adipodermal or acellular dermal matrix (ADM) interposition grafts for fat atrophy of the neophallus following penile implant insertion. METHODS: We retrospectively reviewed the outcomes of glans augmentation in phalloplasty patients presenting with fat atrophy following penile prosthesis insertion. Glans augmentation is performed by making a small posterior coronal incision to preserve the shaft-to-glans dermal blood supply. A plane is made between the glans skin and the capsule of the distal penile implant cylinder. An adipodermal graft or ADM sheet graft is then sized to the glans dissection space and inserted, covering the implant capsule and filling the glans. The graft harvest site and posterior coronal incisions are then closed. The primary postoperative outcome was the recurrence of implant glans skin impingement or erosion. RESULTS: From October 2017 through January 2023, 15 patients underwent glans augmentation after penile prosthesis insertion. The mean follow-up was 20 months. Adipodermal grafts were placed in 12 (80%) patients and ADM grafts in 3 (20%) patients. Two patients developed complications requiring surgical revision and 3 patients are considering a secondary glans augmentation, for a potential surgical revision rate of 33% (5/15). There were no wound infections, implant infections, or erosions. CONCLUSION: Glans augmentation with adipodermal or ADM graft interposition between the glans skin and implant capsule improves the neophallus appearance and may help prevent future implant erosion in phalloplasty patients who develop fat atrophy after penile implant insertion.

OBJECTIVE: To evaluate outcomes of three urethroplasty techniques for pars fixa (PF) urethral strictures and provide a treatment algorithm based on stricture characteristics. The PF is an essential anatomic region of the neourethra created in gender-affirming phalloplasty and metoidioplasty. Urethral strictures in this region present a reparative challenge given its unique anatomy and vascularization. METHODS: A total of 41 urethroplasties performed on 41 patients between March 2018 and June 2021 were reviewed at two surgical centers. A Heineke-Mikulicz (HM) repair was done for strictures under 20â¯mm when the proximal and distal urethral segments were mobile and supported a tension-free closure. Substitution urethroplasty with ventral onlay buccal mucosal graft was utilized for strictures under 40â¯mm not suitable for HM repair. Complex or long (≥40â¯mm) strictures were treated by two-stage Johansen urethroplasty. Success of each surgical approach was defined by a minimum of 12-month follow-up without the need for a repeat intervention. RESULTS: Mean follow-up was 30.2 months (range: 12.4-52.0 months). Mean stricture length was 16.9â¯mm (range: 2-55â¯mm). Most strictures (46%) were located at the distal PF. HM urethroplasty had a success rate of 44% (nâ¯=â¯16). Substitution urethroplasty had a success rate of 92% (nâ¯=â¯13). Two-stage Johansen urethroplasty had a success rate of 75% (nâ¯=â¯12). CONCLUSION: The success rates of PF urethral stricture repair ranged from 44% to 92% depending on the surgical approach, and the best reparative procedure depends on stricture length, severity, and local tissue mobility.

OBJECTIVE: To describe our technique for the infrapubic approach for malleable penile prosthesis (MPP) insertion after phalloplasty in transgender men and review surgical outcomes. METHODS: The infrapubic prosthesis insertion technique involves a horizontal incision anterior to the pubic symphysis, allowing dissection of the neophallus tract and anchor site on the pubic symphysis. Surgical outcomes by a single surgeon using a Spectra or Genesis MPP between October 2017 and May 2022 were retrospectively reviewed. Complications were categorized into erosions, infections, device detachment, device malposition, pain or activity limitation, urethral injury, and flap loss. Implant survival kinetics were assessed by evaluating time to surgical revision. RESULTS: Forty patients underwent infrapubic MPP insertion; 35 patients had a prior radial forearm free flap (RFFF) and 5 had a prior anterolateral thigh flap (ALT) phalloplasty. Of 30 patients who maintained follow-up, mean follow-up was 34.9 months. Complications were not mutually exclusive, with 7 implant detachments from the anchor site, 3 malpositions, 2 with pain/activity limitation, and 1 infection. Surgical revision was required in 12/30 patients (40%). There were no neophallus erosions, flap loss, nor urethral injuries. More complications occurred with the Spectra (9/17 or 53%) than the Genesis MPP (3/13 or 23%), but this was not statistically significant (P = .10). CONCLUSION: Infrapubic insertion in transmen after phalloplasty using commercially available MPPs is safe compared with other post-phalloplasty penile prosthesis insertion techniques, with similarly high surgical revision rates. Further study of techniques is needed to improve outcomes after penile prosthesis insertion in transmen.

Phalloplasty in the female to male transgender patient is a complex operation aimed at creating a functional and aesthetic phallus, external genitalia, and perineum. Functional goals include standing micturition and sexual function with erogenous and tactile sensation as well as the ability to participate in penetrative intercourse. Functional genital reconstruction relies on creating of a fully lengthened urethra from local tissues as well as the provision for additional length via tissue transplantation. This manuscript will review techniques for the creation of perineal urethral segment as well as primary flaps available for the creation of neophallus. Particular emphasis is given to our preferred method of reconstruction: single-stage urethral lengthening with radial forearm flap phalloplasty including a review of surgical techniques and complications.
RESUMEN
Background: There is currently a paucity of data on urethral-related outcomes in metoidioplasty and phalloplasty gender affirming surgery (MaPGAS) with urethral lengthening (UL)and vaginectomy. Methods: A systematic review was performed utilizing MEDLINE, Web of Science, Cochrane Library, Europe PMC, OSF Preprints, and EMBASE. Methodologic quality was scored using Methodological Index for Non-Randomized Studies (MINORS) criteria. Four independent reviewers performed the article evaluation, data extraction, and methodologic quality assessment. Primary outcomes included standing to urinate/pee (STP), penile length, glanular meatus, urethral stricture, fistula, and flap necrosis. Results were summarized qualitatively with descriptive statistics. Results: A total of 2,881 articles of which 11 retrospective reviews of 13 cohorts met criteria; 4.3/16 average (avg) MINORS score. Six metoidioplasty cohorts had an average penile length of 6 cm, 74% reported successful STP, and a quarter developed stricture or fistula. Phalloplasty cohorts included radial forearm flap (RF) and Anterolateral Thigh flap (ALT). Of the 4 RF studies nearly a third developed a stricture or fistula and only one study reported 99% STP with a glanular meatus. Three ALT studies reported no length but had 80-90% STP with a glanular meatus and a quarter with stricture or fistula. Conclusions: Urethral complications in MaPGAS-UL in a cohort with prior vaginectomy are common and variably reported. Patient centered outcome measures as well as clearly defined outcome metrics created in partnership with community members are needed.
RESUMEN
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.
RESUMEN
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.

An abnormal clinical Allen's test is not a definitive exclusion criterion for free radial forearm flap use. A surgical Allen's test may be useful to determine whether flap harvest is feasible in patients with an abnormal clinical Allen's test.
RESUMEN
Single-stage phalloplasty may be accomplished by having both the microsurgical and the reconstructive urology team operate simultaneously. Phalloplasty with pars pendulans urethroplasty is completed by the microsurgeons, and pars fixa urethroplasty, vaginectomy, scrotoplasty, and perineal reconstruction are performed by the reconstructive urologist. Some surgeons prefer separating phalloplasty from the urologic portions of the procedure. The single-staged approach is favored in patients whose ultimate goal is to have an aesthetic, sensate, and functional phallus and scrotum. Complications remain high but are predictably lower in higher-volume centers. Reconstructive urologists manage the urethral complications that develop.

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.
RESUMEN
Gender dysphoria is estimated to occur in approximately 25 million people worldwide, and can have severe psychosocial sequelae. Medical and surgical gender transition can substantially improve quality-of-life outcomes for individuals with gender dysphoria. Individuals seeking to undergo female-to-male (FtM) transition have various surgical options available for gender confirmation, including facial and chest masculinization, body contouring, and genital surgery. The World Professional Association for Transgender Health guidelines should be met before the patient undergoes surgery, to ensure that gender-confirming surgery is appropriate and indicated. Chest masculinization and metoidioplasty or phalloplasty are the most common procedures pursued, and both generally result in high levels of patient satisfaction. Phalloplasty, with a resultant aesthetic and sensate phallus along with implantable prosthetic, can take upwards of a year to accomplish, and is associated with a considerable risk of complications. Urethral complications are most frequent, and can be addressed with revision procedures. A number of scaffolds, implants, and prostheses are now in development to improve outcomes in FtM patients.

BACKGROUND: Phalloplasty with urethral lengthening is the procedure of choice for female-to-male transgender patients who desire an aesthetic phallus and standing micturition, but is associated with complications, including urethral stricture and fistula formation. Horizontal urethra construction can be accomplished with labia minora flaps covered with additional vascularized layers of vestibular tissue when vaginectomy is performed concomitantly with phalloplasty. However, vaginectomy is not a requisite step in phalloplasty, and some individuals may choose to retain their vagina. In these cases, extra layers of vascularized vestibular tissue are not used for horizontal urethra coverage. This study examined the effects of vaginectomy and the addition of extra layers of vascularized vestibular tissue on phalloplasty complication rates. METHODS: A single-center retrospective study of 224 patients who underwent phalloplasty with urethral lengthening was performed. Patients were sorted into vaginectomy and vaginal preservation cohorts and complication rates were assessed. RESULTS: Of 224 total phalloplasty patients, 215 underwent vaginectomy and nine underwent vaginal preservation. Urethral complications occurred in 27 percent of patients with vaginectomy and in 67 percent of patients with vaginal preservation (OR, 0.18; p = 0.02). Vaginectomy was associated with decreased urethral stricture (OR, 0.25; p = 0.047) and urethral fistula formation (OR, 0.13; p = 0.004). Non-urethra-related complications occurred in 15 percent of vaginectomy patients but were not statistically significant (OR, 3.37; p = 0.41). CONCLUSION: Vaginectomy is associated with a significant decrease in urethral stricture and fistula formation, most likely because vaginectomy affords additional horizontal urethroplasty suture line coverage of labia minora flaps with vascularized vestibular tissue. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
