RESUMO
OBJECTIVE: To investigate if predictors of wound complications differed between patients undergoing excision and primary anastomosis urethroplasty (EPA) and augmented urethroplasty. METHODS: The National Surgical Quality Improvement Program database from 2006 to 2018 was queried for male patients undergoing urethroplasty. Thirty-day wound complications were identified and categorized (superficial/deep/organ-space surgical site infections and dehiscence). Multivariable logistic regression was performed to determine risk factors associated with wound complications. Smoking history was defined as current smoker within the past year. RESULTS: Urethroplasty was performed in 2251 males, with 25.46% (n = 573) using a flap or graft. There was no significant difference in wound complications for patients undergoing augmented urethroplasty (n = 17, 2.97%) or EPA (n = 45, 2.68%) (p = 0.9). The augmented group had a higher BMI, longer operative time, and longer length of stay. On multivariable logistic regression, risk factors associated with wound complications for patients undergoing EPA were diabetes (OR 2.56, p = 0.03) and smoking (OR 2.32, p = 0.02). However, these factors were not associated with wound complications in patients undergoing augmented urethroplasty. CONCLUSIONS: Smoking and diabetes were associated with increased wound complications for men undergoing EPA, but not in patients undergoing augmented urethroplasty. Patients with comorbidities associated with worse wound healing may be more likely to have a wound complication when undergoing EPA.
RESUMO
PURPOSE: The treatment of urethral stenosis after a combination of prostatectomy and radiation therapy for prostate cancer is understudied. We evaluate the clinical and patient-related outcomes after dorsal onlay buccal mucosal graft urethroplasty (D-BMGU) in men who underwent prostatectomy and radiation therapy. MATERIALS AND METHODS: A multi-institutional, retrospective review of men with vesicourethral anastomotic stenosis or bulbomembranous urethral stricture disease after radical prostatectomy and radiation therapy from 8 institutions between 2013 to 2021 was performed. The primary outcomes were stenosis recurrence and development of de novo stress urinary incontinence. Secondary outcomes were surgical complications, changes in voiding, and patient-reported satisfaction. RESULTS: Forty-five men were treated with D-BMGU for stenosis following prostatectomy and radiation. There was a total of 7 recurrences. Median follow-up in patients without recurrence was 21 months (IQR 12-24). There were no incidents of de novo incontinence, 28 patients were incontinent pre- and postoperatively, and of the 6 patients managed with suprapubic catheter preoperatively, 4 were continent after repair. Following repair, men had significant improvement in postvoid residual, uroflow, International Prostate Symptom Score, and International Prostate Symptom Score quality-of-life domain. Overall satisfaction was +2 or better in 86.6% of men on the Global Response Assessment. CONCLUSIONS: D-BMGU is a safe, feasible, and effective technique in patients with urethral stenosis after a combination of prostatectomy and radiation therapy. Although our findings suggest this technique may result in lower rates of de novo urinary incontinence compared to conventional urethral transection and excision techniques, head-to-head comparisons are needed.

BACKGROUND: Immuno-oncology therapy (IO) is associated with a variety of treatment-related toxicities. However, the impact of toxicity on the treatment discontinuation rate between males and females is unknown. We hypothesized that immune-related adverse events would lead to more frequent treatment changes in females since autoimmune diseases occur more frequently in females. AIMS: Our aim was to determine if there was a difference in the rate of immunotherapy treatment change due to toxicity between males and females. METHODS AND RESULTS: The Oncology Research Information Exchange Network Avatar Database collected clinical data from 10 United States cancer centers. Of 1035 patients receiving IO, 447 were analyzed, excluding those who did not have documentation noting if a patient changed treatment (n = 573). Fifteen patients with unknown or gender-specific cancer were excluded. All cancer types and stages were included. The primary endpoint was documented treatment change due to toxicity. Four hundred and forty-seven patients (281 males and 166 females) received IO treatment. The most common cancers treated were kidney, skin, and lung for 99, 84, and 54 patients, respectively. Females had a shorter IO course than males (median 3.7 vs. 5.1 months, respectively, p = .02). Fifty-four patients changed treatment due to toxicity. There was no significant difference between females and males on chi-square test (11.4% vs. 12.5%, respectively, p = 0.75) and multivariable logistic regression (OR 0.924, 95% CI 0.453-1.885, p = .827). Significantly more patients with chronic obstructive pulmonary disease (COPD) changed therapy due to toxicity (OR 2.491, 95% CI 1.025-6.054, p = .044). CONCLUSION: Females received a shorter course of IO than males. However, there was no significant difference in the treatment discontinuation rate due to toxicity between males and females receiving IO. Toxicity-related treatment change was associated with COPD.

OBJECTIVE: To describe the surgical technique and evaluate the safety, feasibility, and preliminary outcomes of perineal closure with fasciocutaneous flaps as an alternative to scrotoplasty for large genital wounds. METHODS: Cases of perineal closure with fasciocutaneous flaps and thigh pouch creation for patients having undergone scrotectomy from January 2015 until August 2022 were reviewed for operative details and surgical outcomes. RESULTS: Twenty patients were identified undergoing this procedure. Patients had a median age of 64 (Inter-quartile range [IQR] 58-70), body mass index of 34 (IQR 29-40) and Charlson comorbidity index of 5 (IQR 4-8). Median total wound area was 443â¯cm2 (IQR 225-600). Operative technique in all cases included testicular thigh pouch and fasciocutaneous flap creation for perineal closure; these flaps were raised from the thigh in 18 patients and abdominal wall in 8. This technique resulted in 100% closure rate of the perineum with 3 patients required abdominal split thickness skin grafting (STSG) to complete closure. Complication occurred in 3 patients (15%) with 1 wound infection and 2 episodes of bleeding. Forty percent of patients were discharged home. Median follow-up was 9â¯months with only 1 patient reporting pain related to thigh pouches and none desiring elective scrotoplasty. CONCLUSIONS: Despite large defects, perineal closure was completed in all patients with minimal use of STSG. Complication rates were comparable to other methods despite significant patient frailty and no patients desired staged scrotoplasty. This method of closure adds an option for the complex perineal reconstruction patient.

Few transgender-specific cancer screening recommendations exist. This review aims to cover current guidelines and practice patterns of cancer screening in transgender patients and, where evidence-based data are lacking, to draw from cisgender screening guidelines to suggest best practices for transgender patients based on anatomic inventory. Sufficient evidence does not exist to determine the long-term effects of gender-affirming hormone therapy on cancer risk. In the future, cancer screening and prevention should be focused on anatomic inventory and high-risk behaviors.

Background: extended pelvic lymph node dissection (ePLND) increases the detection rate of lymph node positive prostate cancer compared to a standard pelvic lymph node dissection (sPLND). However, improvement of patient outcomes remains questionable. Here we report and compare 3-year postoperative PSA recurrence rates between patients that underwent sPLND versus ePLND at the time of prostatectomy. Methods: 162 patients received a sPLND (which involvedremoval of periprostatic, external iliac, and obturator lymph nodes bilaterally), and 142 patients received an ePLND (which involved removal of periprostatic, external iliac, obturator, hypogastric, and common iliac nodes bilaterally). Decision to undergo ePLND versus sPLND at our institution was changed in 2016 based on the National Comprehensive Cancer Network guideline. The median follow-up time was 7 and 3 years for sPLND and ePLND patients, respectively. All node-positive patients were offered adjuvant radiotherapy. Kaplan-Meier analysis was carried out to assess the impact of a PLND on early postoperative PSA progression-free survival. Subgroup analyses were done for node-negative and node-positive patients, as well as Gleason score. Results: Gleason score and T stage were not significantly different between patients who received an ePLND and sPLND. The pN1 rate for ePLND and sPLND were 20% (28/142) and 6% (10/162), respectively. There was no difference in the use of adjuvant treatments in the pN0 patients. Significantly, more ePLND pN1 patients received adjuvant androgen deprivation therapy (25/28 vs. 5/10 P = 0.012) and radiation (27/28 vs. 4/10 P = 0.002). Yet, no difference in biochemical recurrence between ePLND and sPLND was observed (P = 0.44). This remained true in subgroup analyses of node-positive (P = 0.26), node-negative (P = 0.78), Gleason Score 6-7 (P = 0.51), and Gleason Score 8-10 (P = 0.77). Conclusions: PLND provided no additional therapeutic benefit, even though ePLND patients were significantly more likely to have node-positive disease and undergo adjuvant treatment, compared to a sPLND.
RESUMO
Radiation therapy (RT) in the management of pelvic cancers remains a clinical challenge to urologists given the sequelae of urethral stricture disease secondary to fibrosis and vascular insults. The objective of this review is to understand the physiology of radiation-induced stricture disease and to educate urologists in clinical practice regarding future prospective options clinicians have to deal with this condition. The management of post-radiation urethral stricture consists of conservative, endoscopic, and primary reconstructive options. Endoscopic approaches remain an option, but with limited long-term success. Despite concerns with graft take, reconstructive options such as urethroplasties in this population with buccal grafts have shown long-term success rates ranging from 70 to 100%. Robotic reconstruction is augmenting previous options with faster recovery times. Radiation-induced stricture disease is challenging with multiple interventions available, but with successful outcomes demonstrated in various cohorts including urethroplasties with buccal grafts and robotic reconstruction.
RESUMO
OBJECTIVE: To outline our step-by-step surgical technique for a transurethral ventral buccal mucosa graft inlay urethroplasty to treat fossa navicularis and distal urethral strictures. METHODS: The transurethral ventral inlay urethroplasty is accomplished in four steps. First, after obtaining proper exposure the cicatrice is excised via a transurethral ventral urethrotomy until the lumen is at least 24fr. Second, double arm 6-0 polydioxanone suture is used to deliver the triangular buccal mucosal graft to the proximal extent of the urethrotomy and secured externally. Third, the graft is secured to the meatus with 5-0 polyglactin sutures and additional 6-0 double arm polydioxanone sutures are used to quilt the graft for spread fixation. Finally, a 16fr silicone catheter is placed. Patients are discharged the same day and return for void trial after one week. A retrospective, single institution review was conducted to include all patients who underwent this procedure with a minimum of 1 year follow-up. Patients were analyzed for recurrences, and pre- and post-operative urine flow rates, post void residuals, and patient questionnaires were also reviewed. RESULTS: 44 patients met our inclusion criteria. Median surgical time was 120 minutes. At a mean follow up of 36 months (IQR 22-50) 95% of patients are patent without additional interventions. The 2 patients that did have stricture recurrence were found to have urethral stenosis that extended more proximally, and both were successfully treated with a dorsal onlay buccal urethroplasty. There were significant improvements in urine flow rate, post void residuals, international prostate symptom score and quality of life scores post operatively. There was no difference in post operative sexual function scores. CONCLUSION: This minimally invasive transurethral ventral urethroplasty has excellent intermediate term outcomes in terms of traditional objective measures of urethroplasty success and patient reported outcomes.

Background and Objective: The overall negative impact of tobacco use on an individual's health has been well documented but the literature on tobacco's impact on post-surgical outcomes, specifically the outcomes after urologic surgery, is not as clear cut. The aim of this narrative review is to provide urologists with the information needed to have a nuanced pre-operative counseling conversation with patients about tobacco use. Here we combine publications on the histologic and physiologic changes induced by nicotine and tobacco use with publications from the wider surgical literature on post-operative outcomes in tobacco users. Methods: A literature search of PubMed, Google Scholar and Medline was performed using iterations of the following terms: tobacco, nicotine, changes, physiologic, histology, post-operative, and surgical. Non-English publications and abstracts were excluded. Inclusion required agreement from all authors and preference was given to human specimens over animal models for the basic science manuscripts and large database and meta-analyses over single institution experiences. Key Content and Findings: Tobacco use results in measurable changes in nearly every organ system in the body. While smokers have increased wound complications, there is no evidence that reconstructive surgery using grafts or flaps fail more frequently in tobacco users. Smokers have an increased risk of respiratory complications following endotracheal intubation. Conclusions: Surgeries should not be canceled due to a patient's inability to cease tobacco use. Urologists and patients should engage in joint decision making regarding the timing and pursuit of elective operations.
RESUMO
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.

OBJECTIVE: To determine the morbidity, mortality, and costs associated with having concurrent venous thromboembolism (VTE) at the time of surgical resection of a renal mass. PATIENTS AND METHODS: We identified 108,430 patients undergoing elective partial or radical nephrectomy for a renal mass from 2013 to 2017 using the Premier Healthcare database. The association of VTE with 90-day complication rates, mortality, ICU admission, readmission, and direct hospital costs (2019 US dollars) was determined with multivariable logistic regression and quantile regression models, respectively. RESULTS: Of the 108,430 patients who underwent elective partial or radical nephrectomy, 1.2% (n = 1301) of patients were diagnosed with a preoperative VTE. Patients with preoperative VTE have higher rates of minor (odds ratio [OR] 1.47, 95% confidence inteval [CI] 1.34-1.62, P < .0001) and major complications (OR 2.53, 95% CI 2.23-2.86, P < .0001), mortality (OR 2.03, 95% CI 1.6-2.57, P < .0001), and readmissions (OR 1.73, 95% CI 1.57-1.90, P < .0001) compared to patients without preoperative VTE at the time of nephrectomy. Notably, the predicted probability for a major complication was significantly higher among patients with preoperative VTE who underwent either partial or radical nephrectomy, irrespective of the surgical approach utilized. Furthermore, rates of all types of complications except endocrine and soft tissue were significantly increased in patients undergoing nephrectomy with preoperative VTE compared to those without VTE. CONCLUSION: VTE at the time of nephrectomy is associated with significantly higher rates of major complications, increased mortality, and higher overall costs. Taken together, these findings have important implications for the counseling and management of renal masses in presence of VTE.

INTRODUCTION: Pelvic lymph node dissection (PLND) is widely performed for staging in men undergoing radical prostatectomy (RP) for prostate cancer. Our goal was to synthesize all available evidence and data to evaluate perioperative complications for two templates of PLND, standard (sPLND) vs extended (ePLND), at the time of RP in patients with prostate cancer. METHODS: A meta-analysis was performed on relevant literature about complications during PLND. Pubmed, Scopus, WebofScience, and Cochrane Library were systematically searched through July 2021. Meta-analysis was conducted with both fixed-effects and random-effects models to estimate risk ratios (RRs) between treatments. A subgroup analysis was also conducted based on surgery type - open vs robotic. RESULTS: 13 (1 randomized clinical trial and 12 observational studies) studies published between 1997 and 2019 with a total of 7,036 patients were analyzed. Pooled data showed complications in a random-effects model was lower in the sPLND group than the ePLND group (RR, 0.62; 95% CI 0.40-0.97). In a subgroup analysis, neither the open surgery subgroup nor the robotic surgery subgroup showed significant differences in complication rate between sPLND and ePLND. CONCLUSION: ePLND is associated with a significantly greater risk of perioperative complication compared to sPLND, but not when comparing these templates performed via a robotic approach. Additional studies comparing the complication rates of sPLND and ePLND when utilizing a robotic approach should be conducted.
RESUMO
Purpose: Approximately 7% of patients with newly diagnosed prostate cancer (PCa) in the US will have have metastatic disease. The dogma that there is no role for surgery in this population has been questioned recently. Here we report long-term outcomes of a phase 1 clinical trial on cytoreductive radical prostatectomy. Materials and methods: This is a multicenter phase 1 trial. The major inclusion criterion was biopsy proven N1M0 or NxM1a/b PCa. Primary end point was the Clavien-Dindo-based major complication rate. Secondary outcomes were biochemical progression and overall survival. RNA-seq correlative study was conducted in nine select cases as a pilot study. Results: Final accrual was 32 patients of which 25 and 7 were cNxM1 and cN1M0, respectively. With the median follow-up of 46 months (interquartile range 31.7 - 52.7 months), 25 out of the 32 patients (75%) were alive at the time of last contact. There were three disparate groups based on the oncologic outcome: favorable, intermediate, and poor. In seven men with favorable response, androgen deprivation therapy was switched to intermittent approach and five remain free of any evidence of disease after more than two years off all systemic therapy with the normalization of serum testosterone. Of these five patients, three had M1 disease. Long-term use of one pad or less per day was 80%. RNA-seq analysis revealed an enriched downregulation of tumor necrosis factor (TNF)-α signature in the favorable group. Conclusion: Overall long-term oncologic outcome of cytoreductive radical prostatectomy was significantly higher than historical results. Importantly, the combination of surgery with systemic therapy may result in a long durable response in a minority of men who present with metastatic PCa.
RESUMO
OBJECTIVE: To assess the effect of tobacco use on oral mucosal tissue harvested for urethroplasty. MATERIALS AND METHODS: Retrospective histologic and immunohistochemical (IHC) evaluation of available buccal mucosa tissue samples from patients that underwent buccal mucosa graft urethroplasty from 2018 to 2020. Patients were asked about tobacco use during pre-operative workup. Patients were counseled on and provided resources to aid in cessation of tobacco use, but surgical cases were not canceled or delayed if patients are unable cease all tobacco use. Patients that ceased use 3 months prior to surgery were considered former users. A single pathologist blinded to the smoking status evaluated the buccal mucosa specimens for histologic changes. Quantitative IHC for p75 and Sox2 were obtained. These investigative markers were selected due to their clear and direct involvement in oral mucosa's regenerative mechanism. Current tobacco users, former users and control patients were compared using ANOVA and Chi-square analyses. RESULTS: Study cohort was 16 current users, 16 former users, 32 controls. Demographics did not differ across the groups. Blinded histologic analysis between all groups found no differences. Pair-wise statistical analysis found greater collagen density in the control group compared to current users (Pâ¯=â¯.01). No differences were found between former and current users or former users and controls. IHC analysis did not demonstrate any difference in the amount or localization of epithelial stem cell markers. CONCLUSION: Our study of buccal mucosa did not find clear or clinically significant histologic or IHC differences between patients with or without a history of tobacco use.

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.

INTRODUCTION: Several guidelines have adopted early integration of palliative intervention (PI) into oncologic care to improve quality of life among patients with advanced malignancies. However, PI utilization patterns and factors associated with its use in metastatic renal cell carcinoma are poorly understood. PATIENTS AND METHODS: Using the National Cancer Database (NCDB), we abstracted patients diagnosed with Stage IV RCC from 2004 to 2014 and evaluated the utilization of PI within this cohort. Socioeconomic and clinical factors were compared for patients receiving and not receiving PI for metastatic RCC. Multivariable logistic regression (MLR) models identified factors that were associated with receipt of PI within overall cohort and treatment-based cohorts. RESULTS: We identified 42,014 patients with Stage IV RCC, of which 7,912 patients received PI. From 2004 to 2014, the use of PI minimally increased from 17% to 20% for Stage IV RCC. MLR analysis demonstrated that increased comorbidities, insurance status, higher education status, facility location, care at a comprehensive cancer program or integrated network, sarcomatoid histology, and treatment type significantly increased the likelihood of PI use. Various socioeconomic, clinical, and geographical factors that are associated with use of PI-based on the treatment received for Stage IV RCC. CONCLUSIONS: While PI utilization has minimally increased for Stage IV RCC, there are several geographic, socioeconomic, and clinical factors that predict its use among patients with Stage IV RCC in a treatment-specific manner. Taken together, this suggests the need for earlier initiation of PI in a more equitable and systematic fashion among patients with metastatic RCC.

The advent and success of buccal mucosal grafts as a substitution material in the urinary tract has changed the landscape of reconstructive urology. Due to its ease to harvest, low morbidity, and advantageous properties, there has been a growing number of applications for buccal mucosal grafts in upper and lower urinary tract reconstruction as well as genital reconstruction. In this article, we review the historical application and the evolution of buccal mucosal grafts and provide an up-to-date review on its utilization in urologic procedures.
