RESUMEN

OBJECTIVE. Masculinizing genital surgeries for transgender individuals are currently performed at only a select few centers; however, radiologists in any geographic region may be confronted with imaging studies of transgender patients. The imaging findings of internal and external genital anatomy of a transgender patient may differ substantially from the imaging findings of a cisgender patient. This article provides the surgical and anatomic basis to allow appropriate interpretation of preoperative and postoperative imaging findings. We also expand on the most common complications and associated imaging findings. CONCLUSION. As these procedures become more commonplace, radiologists will have a growing role in the care of transgender patients and will be faced with new anatomic variants and differential diagnoses. Familiarity with these anatomic variations and postoperative complications is crucial for the radiologist to provide an accurate and useful report.

RESUMEN

We present our technique for second-stage scrotoplasty with autologous tissue augmentation following gender-affirming metoidioplasty. This technique augments the scrotum while removing the upper labia majora and making the penis more visible and accessible. This procedure avoids the need for testicular prostheses and their potential for discomfort, displacement, extrusion, or infection. Our preliminary results show that the complication rate is low.

RESUMEN

OBJECTIVE: To present 2 clitoroplasty techniques-the preputial skin and urethral flap-and describe our rationale for using each technique to construct the clitoro-urethral complex in gender-affirming vaginoplasty. METHODS: For uncircumcised patients or circumcised patients with greater than 2 cm of inner preputial skin and at least 8 cm of shaft skin proximal to the circumcision scar, we use the preputial skin clitoroplasty, a modification of the Ghent style clitoroplasty. The entire corona is used after medial glans and urethral mucosa is excised. The corona is brought together 1 cm from midline to create the visible ovoid clitoris; the remaining coronal tissue remains lateral to the clitoris for erogenous sensation as clitoral corpora. The clitoris is anchored to the proximal tunica, positioned at the level of the adductor longus tendon. The folded neurovascular bundle is fixed in the suprapubic area. The ventral urethral is spatulated and urethral flap approximated to the clitoris. Preputial skin is sutured proximally as tension allows. The clitoro-urethral complex is inset into an opening created in the penile skin flap. For patients with less skin, we use the urethral flap clitoroplasty. More corpus spongiosum is used, as the urethra creates the clitoral hood; this is described in the literature and attributed to Pierre Brassard. The clitoris is inset following a dorsal urethrotomy, with a small collar of preputial skin sewn to the spongiosum and urethral mucosa. The urethra is transected about 1 cm distally. The ventral urethra is then spatulated and the urethroplasty completed. RESULTS: We prefer the preputial skin flap technique for its' greater coronal tissue volume for erogenous sensation and better esthetics, in our opinion. Circumcised patients should have at least 2 cm of skin distal to the circumcision scar. To avoid using skin graft for the introitus-a risk for introital stenosis-shaft skin proximal to the circumcision line should be at least 8 cm. CONCLUSION: We present 2 technical options for clitoroplasty and construction of the clitoro-urethral complex in gender-affirming vaginoplasty.

RESUMEN

OBJECTIVE: To demonstrate an approach to skin management in cases of gender-affirming vaginoplasty in the setting of penoscrotal hypoplasia. Gender-affirming penile inversion vaginoplasty is a procedure that has traditionally relied upon the use of local genital tissues to both construct the vulva and line the neovaginal canal. Improved and earlier access to pubertal suppression has resulted in an increasing number of individuals presenting for vaginoplasty with penoscrotal hypoplasia and significantly less skin available to accomplish the goals of vaginoplasty. Robotic-assisted gender-affirming peritoneal flap vaginoplasty is one solution that has emerged to help address the challenge of limited skin and provide an alternative source of neovaginal lining. Although this technique provides valuable peritoneal tissue that is used to line a large portion of the neovaginal canal, external vulvar construction remains a challenge. Amid a growing number of cases of penoscrotal hypoplasia secondary to pubertal suppression, there is a need for resources that illustrate strategies to deal with these challenging scenarios. In this video the authors demonstrate their approach to vulvar construction in the setting of penoscrotal hypoplasia secondary to pubertal suppression. METHODS: This video demonstrates an approach to skin management during robotic peritoneal flap vaginoplasty in the setting of limited genital skin secondary to pubertal suppression at Tanner stage 2. RESULTS: Penile inversion vaginoplasty typically relies upon the penile skin tube reaching and reconstructing the introitus, and forming the distal aspect of the neovaginal canal. However, in most cases of penoscrotal hypoplasia secondary to pubertal suppression, there will not be enough length of penile skin to reach or construct the introitus. In these cases, the inverted penile skin tube is also often also too narrow in caliber to accommodate passage of a dilator for neovaginal dilation. These clinical scenarios are challenging and often require construction of the introitus with skin graft, complete splitting of the ventral penile skin tube and optimization of remaining skin to form other critical vulvar structures (labia minora and clitoral hood). CONCLUSION: As individuals with penoscrotal hypoplasia continue to present for gender-affirming vaginoplasty procedures, it is important to adjust traditional approaches to vulvar construction and optimize strategies to manage cases with limited genital skin. In this video the authors present their approach to skin management and vulvar construction in gender-affirming vaginoplasty with penoscrotal hypoplasia secondary to pubertal suppression.

RESUMEN

Transgender and non-binary (TGNB) individuals are seeking penile reconstruction in greater numbers; many pursue urethral lengthening surgery with a goal of voiding while standing. Changes in urinary function and urologic complications-i.e., urethrocutaneous fistulae and urinary stricture-are common. Familiarity with presenting symptoms and management strategies for urinary complaints after genital gender-affirming surgery (GGAS) can improve patient counseling and outcomes. We will describe current gender-affirming penile construction options with urethral lengthening and review associated urinary complications that present as urinary incontinence. The incidence and impact of lower urinary tract symptoms after metoidioplasty and phalloplasty are poorly characterized due to limited post-operative follow-up. Post-phalloplasty, urethrocutaneous fistula is the most common urethral complication, ranging in incidence from 15-70%. Assessment of concomitant urethral stricture is necessary. No standard technique exists for management of these fistula or strictures. Metoidioplasty studies report lower rates of stricture and fistula, 2% and 9% respectively. Other common voiding complaints include dribbling, urethral diverticula and vaginal remnants. History and physical exam in the post-GGAS evaluation require understanding of prior surgeries and attempted reconstructive efforts; adjuncts to physical exam include uroflowmetry, retrograde urethrography, voiding cysto-urethrogram, cystoscopy, and MRI. Following gender-affirming penile construction, TGNB patients may experience a host of urinary symptoms and complications that impact quality of life. Due to anatomic differences, symptoms require tailored evaluation which can be done by urologists in an affirming environment.

RESUMEN

We present our systematic approach to incision planning and skin graft excision for gender-affirming vaginoplasty. This approach is adaptable to patients of different body habitus and genital skin surface area, and it allows for early skin graft harvest with predictable wound tension at closure. We also describe how to adapt in cases of severe genital hypoplasia.

RESUMEN

BACKGROUND AND OBJECTIVES: Antibiotic overuse is associated with adverse neonatal outcomes. Many medically underserved centers lack pediatric antibiotic stewardship program (ASP) support. Telestewardship may mitigate this disparity. Authors of this study aimed to determine the effectiveness and safety of a nursery-specific ASP delivered remotely. METHODS: Remote ASP was implemented in 8 medically underserved newborn nurseries using a stepped-wedge, cluster-randomized design over 3 years. This included a 15-month baseline period, a 9-month "step-in" period using random nursery order, and a 12-month postintervention period. The program consisted of education, audit, and feedback; and 24/7 infectious diseases provider-to-provider phone consultation availability. Outcomes included each center's volume of antibiotic use and the proportion of infants exposed to any antibiotics. Safety measures included length of stay, transfer to another facility, sepsis, and mortality. RESULTS: During the study period, there were 9277 infants born (4586 preintervention, 4691 postintervention). Infants exposed to antibiotics declined from 6.2% pre-ASP to 4.2% post-ASP (relative risk 0.68 [95% confidence interval, 0.63% to 0.75%]). Total antibiotic use declined from 117 to 84.1 days of therapy per 1000 patient-days (-28% [95% confidence interval -22% to -34%]. No safety signals were observed. Most provider-to-provider consultations were <5 minutes in duration and occurred during normal business hours. CONCLUSIONS: The number of infants exposed to antibiotics and total antibiotic use declined in medically underserved nurseries after implementing a remote ASP. No adverse safety events were seen, and the remote ASP time demands were manageable. Remote stewardship may be a safe and effective strategy for optimizing antibiotic use in medically underserved newborn nurseries.

RESUMEN

SUMMARY: Genital masculinizing gender-affirming surgery is a growing field. Because of a spectrum of gender identity, gender expression, sexual expression, patient desires, and patient tolerance for complications, options for surgery vary accordingly. Shaft-only phalloplasty avoids urethral lengthening, but may still be accompanied by hysterectomy, vaginectomy, scrotoplasty, clitoroplasty (burying of the clitoris), glansplasty, and placement of erectile devices and testicular implants. Patients who desire retention of vaginal canal patency are candidates for vaginal preservation vulvoscrotoplasty; however, there is a paucity of literature describing the procedure and its outcomes. In this article, the authors review the technique used by the senior author at Oregon Health and Science University and report surgical outcomes for four patients. Future studies regarding patient-recorded outcome measures, aesthetics, sexual function, urologic function, patient satisfaction, and conversion to other options will help surgeons better understand patients pursuing gender-affirming surgery through shaft-only phalloplasty.

RESUMEN

OBJECTIVES: There are multiple approaches to vaginectomy for the purpose of masculinizing gender-affirming genital surgery including mucosal fulguration and excision. The outcomes of the approaches are not well described. We aim to describe the surgical outcomes of gender-affirming vaginectomy and colpocleisis by complete mucosal excision. METHODS: We performed a case series study of 40 transmasculine patients who underwent gender-affirming vaginectomy and colpocleisis. Vaginectomy was performed by complete excision of the vaginal mucosa via a transperineal approach. We recorded perioperative outcomes and operative time. We performed a multivariate analysis to assess patient factors on operative outcomes. RESULTS: Forty vaginectomies were performed between September 2016 and April 2019, 27 (67.5%) in phalloplasty patients and 13 (32.5%) in metoidioplasty patients. Perioperative complications included 2 blood transfusions, 1 pelvic hematoma, and 1 Clostridium cifficile colitis. No urethral fistulae to the vaginal space, mucoceles, or visceral injures were seen with a median follow-up of 7.7 months. Operative time decreased significantly with later surgery year. CONCLUSIONS: This is a large series studying the outcomes of gender-affirming vaginectomy by complete mucosal excision approach in the literature. Perioperative complications were low. Operative time decreased overtime such that after approximately 20 cases, the procedure fairly consistently takes 2 to 2.5 hours to perform.

RESUMEN

PURPOSE: We assessed penile and bulbospongiosus measurements to develop a quantitative guide to select the surgical approach (perineal vs transscrotal vs transcorporeal) to artificial urinary sphincter cuff placement. MATERIALS AND METHODS: We retrospectively reviewed the intraoperative records of 100 men who underwent artificial urinary sphincter placement (43) or anastomotic urethroplasty (57) from February 2008 to June 2009. Correlations between penile (stretched length and circumference at the shaft base) and bulbospongiosus (distal and proximal circumference) measurements were assessed. Cases were analyzed according to 2 penile circumference groups, including group 1-8.0 cm or less and group 2-8.5 or more. RESULTS: Mean proximal bulbospongiosus circumference was uniformly larger than distal bulbospongiosus circumference (4.5 vs 3.9 cm). It was about 50% of the penile shaft circumference (mean 8.9 cm, r = 0.70). In group 1 men the average distal bulbospongiosus circumference was 3.4 cm. They were more likely to undergo transcorporeal artificial urinary sphincter cuff placement than those in group 2, who had an average distal bulbospongiosus circumference of 4.1 cm (8 of 22 or 36% vs 1 of 21 or 5%, OR 11.4). Penile length correlated less robustly with distal and proximal bulbospongiosus circumference (r = 0.39 and 0.43, respectively). Patients with urethroplasty had significantly larger urethral measurements than those with the artificial urinary sphincter (proximal and distal bulbospongiosus circumference 4.9 vs 3.7 and 4.1 vs 3.2, respectively) but were significantly younger (47 vs 67 years), and less likely to have erectile dysfunction (11 of 57 vs 34 of 43) or to have undergone radical prostatectomy (0 of 57 vs 37 of 43). CONCLUSIONS: Bulbospongiosus circumference appears to be proportional to penile circumference. The distal bulbospongiosus is uniformly smaller than the proximal bulbospongiosus. The potential need for a perineal or transcorporeal approach to artificial urinary sphincter placement can be anticipated by penile circumference measurements and a combination of clinical factors, such as older patient age, history of radical prostatectomy and impotence.

RESUMEN

PURPOSE: We identified computerized tomography findings associated with the need for urgent intervention for hemostasis after traumatic renal injury to update and refine the American Association for the Surgery of Trauma Organ Injury Scale for renal trauma. MATERIALS AND METHODS: We retrospectively reviewed the records of consecutive patients presenting to our level I trauma center from 1999 to 2008 with American Association for the Surgery of Trauma grades 3 and 4 renal injury. In all patients initial abdominal computerized tomography was done soon after presentation to the emergency department before renal intervention. All images were interpreted by a staff radiologist and urologist blinded to clinical outcomes. Novel radiographic features (perirenal hematoma size, intravascular contrast extravasation and renal laceration site) were analyzed and correlated with the invasive intervention rate to control life threatening bleeding. RESULTS: Of 299 patients hospitalized with renal injury 102 met study inclusion criteria. Increased perirenal hematoma size (perirenal hematoma rim distance greater than 3.5 cm), intravascular contrast extravasation and a medial renal laceration site were important radiographic risk factors significantly associated with intervention for bleeding after renal trauma. Analyzing these radiographic characteristics collectively showed that patients with 0 or 1 risk factor were at 7.1% risk for intervention and those with 2 or 3 were at remarkably higher risk, that is 66.7% (OR 26.0, 95% CI 7.20-93.9, p <0.0001). CONCLUSIONS: On radiography a large perirenal hematoma, intravascular contrast extravasation and medial renal laceration are important risk factors associated with the need for urgent hemostatic intervention after renal trauma. Assessing these computerized tomography characteristics collectively shows that American Association for the Surgery of Trauma grade 4 renal injuries can and should be substratified into grades 4a (low risk) and 4b (high risk).

RESUMEN

OBJECTIVE: To present our 4-year experience of using a minimally invasive technique, penoscrotal plication (PSP), as a uniform treatment for men with debilitating penile curvature resulting from Peyronie's disease. PATIENTS AND METHODS: In 48 men (median age 58.7 years) with penile curvature the penis was reconstructed by imbricating the tunica albuginea opposite the curvature with multiple nonabsorbable sutures. All patients, regardless of the degree or direction of curvature, were approached through a small penoscrotal incision made without degloving the penis. Detailed measurements of penile shaft angle and stretched penile length were recorded and analysed before and after reconstruction, and the numbers of sutures required for correction were documented. RESULTS: Nearly all patients had dorsal and/or lateral deformities that were easily corrected via a ventral penoscrotal incision. The median (range) degree of correction was 28 (18-55) degrees and number of sutures used was 6 (4-17). Stretched penile length measurements before and after plication showed no significant difference. A single PSP procedure was successful in 45/48 (93%) patients; two were dissatisfied with the correction, one having repeat plication and the other a penile prosthesis; one other required a suture release for pain. CONCLUSIONS: PSP is safe and effective and should be considered even for cases with severe or biplanar curvature.

RESUMEN

BACKGROUND: Although the American Association of the Surgery for Trauma Organ Injury Scale is the gold standard for staging renal trauma, it does not address characteristics of perirenal hematomas that may indicate significant hemorrhage. Angiographic embolization has become well established as an effective method for achieving hemostasis. We evaluated two novel radiographic indicators--perirenal hematoma size and intravascular contrast extravasation (ICE)--to test their association with subsequent angiographic embolization. METHODS: Among 194 patients with renal trauma between 1999 and 2004, 52 having a grade 3 (n = 33) or grade 4 (n = 19) renal laceration were identified. Computed tomography scans were reviewed by a staff radiologist and urologist blinded to outcomes. ICE was defined as contrast within the perirenal hematoma during the portal venous phase having signal density matching contrast in the renal artery. Hematoma size was determined in four ways: hematoma area (HA), hematoma to kidney area ratio (HKR), difference between hematoma and kidney area (HKD), and perirenal hematoma rim distance (PRD). RESULTS: Of the 52 patients, 8 had ICE and 4 of these (50%) required embolization, whereas none of the 42 (0%) patients without ICE needed embolization (p = 0.001). Likewise, all four measures of perirenal hematoma size assessed were significantly greater in patients receiving embolization [HA (128.3 vs. 75.4 cm, p = 0.009), HKR (2.75 vs. 1.65, p = 0.008), HKD (76.5 vs. 30.2 cm, p = 0.006), and PRD (4.0 vs. 2.5 cm, p = 0.041)]. CONCLUSION: Perirenal hematoma size and ICE are readily detectible radiographic features and are associated with the need for angiographic embolization.

RESUMEN

Endocrinologists are at the front line for providing gender-affirming care for transgender patients by managing hormone regiments before and after surgery. This article provides the endocrinologist with an overview of the surgical options for transgender and nonbinary patients considering gender confirmation surgery, including feminizing and masculinizing facial, chest, and genital reconstruction. Discussions of the impact of hormones on surgery, and vice versa, as well as information on surgical decision making are provided to help inform patient education via the endocrinologist.

RESUMEN

Phalloplasty is an exceptionally complicated reconstructive procedure that attempts to create a structure that is penis-like. As patient goals vary widely, it is helpful to think about phalloplasty as a modular set of procedures that can be combined, mixed and matched to meet the needs of each individual patient while also taking into account their anatomy. Each module-but particularly the shaft and penile urethra-can be performed using a variety of techniques. To date, there is no consensus among surgeons regarding the optimum staging of the reconstructive steps. Our primary goal is to outline the most frequently performed and reported options in phallic reconstruction and outline the various considerations that go into choosing a given sequence of procedures for the specific patient. The secondary goal of this article is to describe the complications common to each of those modules and how they interact when combined.

RESUMEN

OBJECTIVE: To characterize spermatogenesis in the estrogenized transgender patient. MATERIALS AND METHODS: This is a retrospective, single-center, cross-sectional study. Seventy-two transgender women underwent gender-affirming orchiectomy between May 2015 and January 2017. All were on long-term (>1 year) cross-sex hormonal therapy prior to orchiectomy. Patient data were obtained via chart review. Histologic analysis was performed by a pathology resident under the supervision of a genitourinary pathologist. The main outcome is histologic presence of germ cells and presence of spermatids (a proxy for preserved spermatogenesis) in orchiectomy specimens. RESULTS: There were 141 pathologic specimens available for analysis. Germ cells were present in 114 out of 141 (81%) testicles. Spermatids were present in 57 (40%) testicles. Presence of germ cells was associated with older age (43 vs 35 years, P = .007) and increased testicular weight (28.6 g vs 19.3 g, P <.001). Presence of spermatids was associated with increased weight (31.5 g vs 23.3 g, P <.001) and volume (20.3 mL vs 12.6 mL, P <.001). There was a linear correlation between testis volume and preserved spermatogenesis (Pearson's r = 0.448, P <.001). CONCLUSION: Despite long-term hormone therapy, the majority (80%) of transgender women have germ cells present in the testicle. Spermatogenesis is preserved in approximately 40% of these individuals. Duration of hormonal therapy did not affect the degree of preservation of germ cells or spermatogenesis but starting hormonal treatment at a younger age may be associated with decreased germ cells in the testicle. Volume of testicles predict presence of preserved spermatogenesis.

RESUMEN

BACKGROUND: Expansion of insurance coverage for gender confirmation surgery (GCS) has led to a large demand for GCS in the US. We sought to determine the financial impact of providing comprehensive GCS services at an academic medical center. METHODS: This was a cross-sectional study of patients older than 18 years who presented for GCS between January 1, 2015 and July 31, 2018 at a single academic medical center. The use of GCS services and associated work relative value units is reported. Departmental and hospital-level operating (profit) margins are reported relative to other hospital services, as well as the payer mix. RESULTS: A total of 818 patients underwent 970 GCS procedures between January 2015 and July 2018. Mean (SD) age was 35.32 (12.84) years. Four hundred and ninety-three (60.3%) patients underwent a masculinizing procedure, and 325 (39.7%) had a feminizing procedure. The most commonly performed procedure was chest masculinization (n = 403). The GCS case volume grew to generate 23.8% (plastic surgery) and 17.8% (urology) of total annual departmental work relative value units, and was associated with positive operating margins after recouping new faculty hiring costs. There were positive operating margins for GCS procedures for the hospital system that compare favorably with other common procedures and admissions. Medicare and Medicaid remained the most common payer throughout the study period, but dropped from 70% in 2015 to 48% in 2018. CONCLUSIONS: We found that providing GCS at our academic medical center is profitable for both the surgical department and the hospital system. This suggests such a program can be a favorable addition to academic medical centers in the US.

RESUMEN

OBJECTIVE: To analyze a series of clinical risk factors associated with pretreatment urethral atrophy. METHODS: We retrospectively reviewed 301 patients who underwent artificial urinary sphincter (AUS) placement between September 2009 and November 2015; of these, 60 (19.9%) transcorporal cuff patients were excluded. Patients were stratified into 2 groups based on intraoperative spongiosal circumference measurements. Men with urethral atrophy (3.5 cm cuff size) were compared to controls (≥4 cm cuff size). Chi-square test, Mann-Whitney U test, and logistic regression analyses were performed to determine risk factors for urethral atrophy. RESULTS: Among 241 AUS patients analyzed, urethral atrophy was present in 151 patients (62.7%) compared to 90 patients (37.3%) who received larger cuffs (range 4-5.5 cm). Patients with urethral atrophy were older (71.1years vs 68.3 years; P < .02), more likely to have received radiation (52.9% vs. 33.3%; P < .007), and had a longer time interval between prostate cancer treatment and AUS surgery (8.9 years vs. 6.6 years; P < .033). On multivariable analysis, radiation therapy was independently associated with risk of urethral atrophy (odds ratio 1.77, 95% confidence interval: 1.01-3.13; P = .046), whereas greater time between cancer therapy and incontinence surgery approached clinical significance (odds ratio 1.05, 95% confidence interval 1.00-1.09; P = .05). CONCLUSION: History of radiation therapy and increasing length of time from prostate cancer treatment are associated with urethral atrophy before AUS placement.

RESUMEN

OBJECTIVE: To report our experience with permanent urethral ligation for severe incontinence among men with end-stage urethra. MATERIALS AND METHODS: From our institutional artificial urinary sphincter database of 512 patients from 2010 to 2016, 10 men underwent permanent urethral ligation with concurrent suprapubic tube diversion following recurrent artificial urinary sphincter cuff erosion. Clinical characteristics and outcomes were evaluated. Quality of life was assessed using the Michigan Incontinence Symptom Index and the Patient Global Index of Improvement. RESULTS: Urethral ligation resulted in resolution of incontinence in 8 men (80%), including 7 (70%) after 1 surgery and in 1 (10%) after a single revision. The average American Society of Anesthesiologists physical status rating was 2.7 (range 2-3). Seven patients (70%) experienced postoperative complications (4 Clavien-Dindo grade II complications [1 Clostridium difficile infection, 3 refractory bladder spasms) and 5 grade III complications (2 abscesses, 2 urethrocutaneous fistula, and 1 bladder stone formation]). Overall, satisfactory Michigan Incontinence Symptom Index urinary scores were reported in 8 (80%) men. On the Patient Global Index of Improvement, 6 (60%) men reported improvement in overall condition following surgery. All men (10/10) stated that they would recommend this procedure to others. CONCLUSION: For debilitated men with end-stage urethra and severe refractory stress urinary incontinence, permanent urethral ligation with chronic suprapubic tube drainage can restore continence and improve quality of life without the need for more invasive formal urinary diversion, though with a high risk of complication.

RESUMEN

Urethral reconstruction is now considered optimal therapy for most men presenting with symptomatic urethral strictures. The rapid development of innovative tissue transfer techniques over the past decade provides today's reconstructive urologist with a high probability of achieving excellent long-term outcomes after urethroplasty, even in the reoperative setting. Fundamental principles such as accurate initial stricture staging by urethrography, along with critical assessment of both stricture severity and tissue quality during urethroplasty are critical for success. This review illustrates the way in which stricture length, location, severity, and etiology influences the application of reconstructive techniques during contemporary urethroplasty.
