Nocturnal penile tumescence devices: past, present and future.

Erectile function is an important part of men's health that can significantly impact quality of life. Naturally occurring nighttime erections experienced by men throughout their lifespan provides insight into penile health as well as overall health. Nocturnal penile tumescence (NPT) and nocturnal penile tumescence and rigidity (NPTR) devices that can non-invasively evaluate the presence and quality of erections can have valuable diagnostic and clinical utility. Early devices have several limitations that limit their current use. New, wearable devices have promising applications for the evaluation of erectile function over time. Continued advancements in this technology have the potential to render future generations of these devices as invaluable tools that are useful for both men and healthcare professionals.

Incidence and Risk Factors for Postoperative Venous Thromboembolism After Gender Affirming Vaginoplasty: A Retrospective Analysis of a Large Insurance Claims Database.

OBJECTIVES: To investigate the incidence and associated risk factors of venous thromboembolism (VTE) after gender affirming vaginoplasty. METHODS: We searched International Business Machines Corporation (IBM) Marketscan, a commercial claims database, for Current Procedural Terminology and International Classification of Diseases (ICD) procedure codes to identify patients who underwent gender affirming vaginoplasty from 2011-2020. We quantified deep venous thrombosis and pulmonary embolism using ICD-9 and ICD-10 codes found within 90 days after surgery. Univariate and multivariate analyses were performed to establish association between VTE events and age, residency location, and comorbidities. RESULTS: We identified 1588 patients who underwent gender affirming vaginoplasty. Overall, 1.1% of patients experienced a VTE within 90 days following surgery. Patients who experienced postoperative VTE were older, more likely to have had a prior VTE, less likely to be from an urban area, and more likely to have a higher Charlson Comorbidity Index score. Among patients with postoperative VTE, 47.1% had previous VTE. Among patients without a postoperative VTE, 1.3% had previous VTE. CONCLUSION: In patients undergoing gender affirming vaginoplasty, the incidence of postoperative VTE was 1.1%. Older age, rurality, increased comorbidities, and prior VTE were associated with increased risk of postoperative VTE. Current guidelines do not recommend cessation of gender affirming hormone therapy (GAHT) prior to vaginoplasty. Further research is needed to evaluate if certain high-risk patients would benefit from perioperative adjustment of GAHT or perioperative VTE prophylaxis.

Evolution of the basic semen analysis and processing sperm.

PURPOSE OF REVIEW: The sixth edition of the World Health Organization (WHO) laboratory manual for the examination and processing of human semen was recently published with specific step-by-step instructions for semen evaluation and sperm processing. Point-of-care (POC) testing for semen evaluation and microfluidics for sperm processing are rapidly evolving technologies that could impact how we evaluate and process sperm. Understanding the updated manual in the context of these novel technologies is important. RECENT FINDINGS: Proper standardization of semen evaluation and sperm processing will allow for consistent high-quality results among laboratories worldwide. POC testing could improve access to semen evaluations that generate referrals to male infertility specialists for further assessment. Microfluidics can select functional sperm with decreased DNA fragmentation in semen and testicular biopsy samples for assisted reproductive technology (ART). Clinical outcomes, such as pregnancy rates and live birth rates, have not been shown to be consistently improved with these technologies compared to conventional techniques, although high level evidence research in this area is limited. SUMMARY: POC testing and microfluidics have the potential to be combined with machine learning technologies to improve fertility care. If these technologies are appropriately optimized, they could change how we evaluate and process sperm, and potentially lead to improved ART outcomes.

Gender Affirmation Surgery, Transfeminine.

Feminizing genital surgery for transgender women is a feasible and fulfilling intervention in alleviating gender dysphoria. Several techniques in neovaginal creation can be offered, including vulvoplasty, penile skin inversion vaginoplasty, peritoneal vaginoplasty, and enteric vaginoplasty. Complication rates are low and often managed conservatively. Favorable sexual function outcomes indicate high satisfaction rates.

Long-term outcomes from a multi-institutional experience with prefabricated composite gracilis-buccal mucosal flap for reconstruction of devastated urethras.

PURPOSE: Patients with devastated bulbar urethras have limited surgical options to restore normal upright voiding. We investigated the long-term feasibility of using two independently vascularized urethral hemi-plates lined with buccal mucosal graft (BMG) to treat these patients. METHODS: A multi-institutional retrospective review was conducted for patients that underwent this staged repair. In stage-1, the affected urethra is dissected and removed or prepared for a dorsal inlay augmentation. Two BMG segments are harvested; one graft is quilted on corpora cavernosa and urethra, creating an augmented perineal urethrostomy, and the other is quilted on the exposed distal gracilis muscle. Stage-2 utilizes the gracilis-BMG composite to recreate ventral bulbar urethra. The primary outcome measure was stricture recurrence. Secondary outcome measures included patient-reported outcome measures (PROMs). RESULTS: Five patients with mean age of 50 years (45-56) underwent staged repairs at two institutions between 7/2014 and 4/2016. All patients presented with suprapubic tubes and underwent at least one prior failed repair (1-9). Mean stricture length was 7.2 cm (5-9). Mean time between stage-1 and stage-2 repairs was 6.2 weeks (1-10). At a mean follow-up of 61 months (39-87), there were no recurrences. The mean uroflow was 20 cc/s (9-42) with a mean PVR of 59 cc (0-157). Four patients completed post-operative surveys; all reported at least a moderate improvement in their condition on Global Response Assessment (GRA), and a mean IPSS of 7.3 (0-26). CONCLUSIONS: Our bi-institutional case series demonstrates that this technique is a feasible option for devastated urethras with long-term durability.

Staged Urethroplasty for Reconstruction of Long Complex Pendulous Strictures of a Neophallic Urethra.

BACKGROUND: Post-phalloplasty, patients may present with urologic complications, including strictures, urethrocutaneous fistulas and vaginal cavity remnants.1-3 OBJECTIVE: To demonstrate the feasibility of staged repairs for long complex neophallus strictures. METHODS: All post-phalloplasty patients who underwent pendulous (pars pendulans) or panurethral urethroplasty for strictures >7 cm were identified. In preparation for surgery patients were co-managed with their local providers, whenever possible, in treating symptomatic infections with culture-specific antibiotics, draining abscess and managing suprapubic catheters. During Stage-1, a ventral incision through the perineum and neophallus was created to expose remnants of the neo-urethral plate. Additional findings (fistula/remnant cavity) were treated at this stage if found, along with re-mobilization of a previously placed gracilis flap. The neourethral plate was augmented with buccal mucosal graft (BMG) with a goal of achieving an approximately 3-cm-wide plate. The lateral neourethral edges were sutured to the edges of the skin incision creating a temporary perineal urethrostomy. Stage-2 was performed in a delayed fashion and included mobilization and tubularization of the neourethra, with additional oral mucosa inlay (BMG or lingual), if needed, followed by a multi-layer closure. Postoperatively, patients were assessed in clinic when possible, or via telemedicine appointments for urethral patency, and queried using patient-reported outcome measures. Failures were defined as need for additional revisions or urethral instrumentation. RESULTS: Twenty-one patients presented between December 2013 and July 2021 with urinary obstruction due to long penile strictures. Seventeen patients, mean age 33 (22-58), elected to undergo staged reconstruction. Prior phalloplasty techniques included radial forearm flap phalloplasty in 15/17 and anterolateral thigh flap in 2/17. In 11/17 patients BMG was previously used during phalloplasty for urethral prelamination.4 Mean stricture length was 12 cm (7-17). Concurrent procedures during Stage-1 included re-harvesting BMG (11/17), gracilis flap re-mobilization (7/17) and redo-vaginectomy (5/17).5 During Stage-2, 14 patients (82%) required additional oral graft inlays: lingual 6/14 (including 2 bilateral), BMG 5/14 (including 1 bilateral) and lingual+BMG in 3/14. At a mean follow-up of 24 months (4-77), there were 2 failures (12%). Thirteen patients completed follow-up questionnaires and all reported upright voiding and at least a moderate improvement in their condition on Global Response Assessment: +3 (markedly improved) in 11/13 (85%), and +2 (moderately improved) in 2/13 (15%). CONCLUSION: A staged urethroplasty is a feasible option for transgender men with long complex penile strictures of the neophallus. This technique demonstrates promising early functional outcomes and high patient satisfaction.

Sexual Functioning of Transgender Females Post-Vaginoplasty: Evaluation, Outcomes and Treatment Strategies for Sexual Dysfunction.

INTRODUCTION: Transfeminine genital reconstructive surgery is an important part of gender affirmation for many transgender women. Sexual health post-vaginoplasty is an important aspect of quality of life that can have a significant impact on overall well-being. OBJECTIVES: The objective of this review is to provide a summary of the literature on the sexual outcomes of transgender females post-vaginoplasty and identify treatment strategies for those experiencing sexual dysfunction. METHODS: A literature review was conducted with a focus on sexual health outcomes in transgender females post-vaginoplasty as well as treatment options for sexual dysfunction. RESULTS: Penile inversion vaginoplasty with or without free skin grafts or local tissue flaps and intestinal vaginoplasty are the options available to patients interested in transfeminine genital reconstructive surgery with a neovagina. Sexual satisfaction post-vaginoplasty is high regardless of the vaginoplasty technique, however up to 29% of patients may be diagnosed with a sexual dysfunction due to associated distress with a sexual function disturbance. Hormone treatment, pelvic floor physical therapy, sex therapy, and sex surrogacy are treatment options for patients with sexual dysfunctions. CONCLUSION: Patient reported outcome measures appropriately validated for this patient population are necessary to better understand sexual function outcomes, sexual dysfunction and treatment options for post-vaginoplasty patients.

Reservoir induced bladder rupture: a complication of inflatable penile prosthesis revision surgery.

Reservoir induced bladder rupture is a rare complication of inflatable penile prosthesis (IPP) revision surgery. Our aim is to review the literature and describe our experience with this complication using two case reports that involved reusing an in-situ reservoir. In each case, an episode of gross hematuria indicated that a bladder rupture had occurred. From our experience, we propose ways to possibly avoid and if necessary, manage this rare complication.

Histological Evaluation of Vaginal Cavity Remnants Excised During Neourethral Stricture Repair in Transgender Men.

OBJECTIVE: To determine the prevalence of patients who require vaginal cavity remnant excision and obliteration during neourethral stricture repair and to characterize the histological composition of the excised tissue. METHODS: A retrospective review was performed of all transgender men who underwent neourethral stricture repair. Preoperative imaging and operative reports were reviewed to determine the presence of a vaginal cavity remnant that was excised and obliterated during neourethral reconstruction. Pathology slides were reviewed by 2 pathologists to determine if there was presence of stratified squamous epithelium consistent with vaginal tissue within the vaginal cavity remnant. RESULTS: A total of 47 consecutive transgender men underwent neourethral stricture repair between January 2014 and December 2020. Of these, 18 patients (38%) with a mean age of 37 years (23-59) underwent excision and obliteration of a vaginal cavity remnant. Seventy eight percent (14/18) had a prior phalloplasty and 22% (4/18) had a prior metoidioplasty. Primary vaginectomy type was not associated with whether or not a patient had a vaginal cavity remnant (P = .12). Histological evaluation demonstrated the presence of vaginal epithelium in all vaginal cavity remnant specimens. CONCLUSION: A high percentage of transgender men with neourethral strictures present with vaginal cavity remnants despite prior vaginectomy. Pathological evaluation confirms that all vaginal cavity remnant specimens contain vaginal epithelium that was either incompletely excised or regenerated. While the implications of this residual vaginal epithelium require further investigation, total removal of vaginal tissue primarily or during reconstruction is important given the risk of associated symptoms.

One or Two Stage Buccal Augmented Urethroplasty has a High Success Rate in Treating Post Phalloplasty Anastomotic Urethral Stricture.

OBJECTIVE: To describe the outcomes of single-stage and staged repairs in properly selected patients with phalloplasty anastomotic strictures. METHODS: A bi-institutional retrospective review was performed of all patients who underwent anastomotic stricture repairs between 7/2014-8/2020. Those who had prior augmented urethroplasties or poorly vascularized tissue underwent two-stage repairs (Group-2), all others underwent single-stage repair with a double-face (dorsal inlay and ventral onlay) buccal mucosal graft urethroplasty (Group-1). Postoperatively, urethral patency and patient reported outcome measures (PROMs) were assessed. RESULTS: Twenty-three patients with anastomotic strictures were identified. Fourteen patients met inclusion criteria and had 1-year follow-up (9 in Group-1; 5 in Group-2). Nine patients (64%) had prior failed interventions (56% Group-1; 80% Group-2). At a mean follow-up of 33.9 (Group-1) and 35.2 months (Group-2) there were two stricture recurrences in Group-1 (22%) and none in Group-2. PROMs were completed by 12 patients. All patients reported the ability to void standing. Post-void dribbling was present in the majority of patients (7/7 Group-1; 2/4 in Group-2). Mean IPSS was 3.9 (0-14) for Group-1 and 1 (0-3) for Group-2. All reported at least a moderate improvement in their condition on GRA (Group-1 +3 71%, +2 29%; Group-2 +3 100%). CONCLUSION: Single-stage repairs are feasible for patients with anastomotic strictures who have well vascularized tissue and no prior single-stage buccal mucosa augmented urethroplasty failures. Staged repairs are feasible for patients with poor tissue quality. Proper patient selection is important for successful reconstruction.

Single-stage Double-face Buccal Mucosal Graft Urethroplasty for Neophallus Anastomotic Strictures.

OBJECTIVE: After gender-affirming phalloplasty the anastomosis between the perineal urethra (pars fixa) and the penile urethra is the most common site of stricture.1 Excisional urethroplasty after phalloplasty is known to have high failure rates due to poor vascularization of neourethra.2 Our objective is to demonstrate the feasibility of a single-stage repair of neophallus anastomotic strictures using a "double-face" urethroplasty technique. METHODS: All patients who presented with anastomotic neophallus strictures and underwent a "double-face" buccal mucosal graft (BMG) urethroplasty were identified. Preoperatively, all patients had retrograde urethrogram and voiding cystourethrogram. Intraoperatively, pars fixa was exposed through a perineal dissection. A ventral sagittal urethrotomy followed by a dorsal urethrotomy was carried 1-2 cm beyond the stenotic area. An Asopa-type BMG inlay was performed by securing an appropriately sized BMG dorsally.3 A separate ventral graft was placed in a "double-face" technique described by Palminteri.4 Surrounding tissue analogous to Martius flap was rotated medially to support the ventral graft. Retrograde urethrogram and voiding cystourethrogram and voiding trials were performed three weeks postoperatively. Patients were followed for stricture recurrence and patient-reported outcome measures. RESULTS: Thirty-one patients presented for neophallus stricture repair between December 2014 and December 2019. Of these, 9 underwent a single-stage repair of an anastomotic stricture after radial forearm flap phalloplasty, 8 were available for follow-up. At a mean follow-up of 31 months (10-56), there were 2 (25%) stricture recurrences treated with perineal urethrostomy in 1 patient and staged urethroplasty in another. Ultimately, 7 of 8 patients reported the ability to void in upright position and all reported an improvement in their condition following surgery. Mean International Prostate Symptom Score postoperatively was 3.1 (0-11), International Prostate Symptom Score -QOL 0.9 (0-3). CONCLUSION: A single-stage double-face BMG urethroplasty is a feasible option for select patients with post-phalloplasty anastomotic strictures,5 demonstrating promising early surgical success rates and high patient satisfaction on patient-reported outcome measures.

Management of Vaginoplasty and Phalloplasty Complications.

As more transgender patients undergo gender-affirming genital reconstructive surgery, such as vaginoplasty and phalloplasty, it is imperative for health care providers, including urologists, to understand the new anatomy and most common complications to diagnose and treat patients effectively. Although there have been several modifications to prior techniques as well as development of new techniques over the years, complications are still common after vaginoplasty and phalloplasty. This article focuses on the most common complications as well as the evaluation and management of those complications.
