Abstract
PURPOSE Anterior urethral stricture disease (aUSD) is a complex, heterogeneous condition that is idiopathic in origin for most men. This gap in knowledge rarely affects the current management strategy for aUSD, as urethroplasty does not generally consider etiology. However, as we transition towards personalized, minimally invasive treatments for aUSD and begin to consider aUSD prevention strategies, disease pathophysiology will become increasingly important. The purpose of this study was to perform a deep phenotype of men undergoing anterior urethroplasty for aUSD. We hypothesized that unique biologic signatures and potential targets for intervention would emerge based on stricture presence/absence, stricture etiology, and the presence/absence of stricture inflammation. MATERIALS AND METHODS Men with aUSD undergoing urethroplasty were recruited from one of 5 participating centers. Enrollees provided urethral stricture tissue and blood/serum on the day of surgery and completed patient-reported outcome measure questionnaires both pre- and postoperatively. The initial study had 3 aims: (1) to determine pediatric and adult subacute and repeated perineal trauma (SRPT) exposures using a study-specific SRPT questionnaire, (2) to determine the degree of inflammation and fibrosis in aUSD and peri-aUSD (normal urethra) tissue, and (3) to determine levels of systemic inflammatory and fibrotic cytokines. Two controls groups provided serum (normal vasectomy patients) and urethral tissue (autopsy patients). Cohorts were based on the presence/absence of stricture, by presumed stricture etiology (idiopathic, traumatic/iatrogenic, lichen sclerosus [LS]), and by the presence/absence of stricture inflammation. RESULTS Of 138 enrolled men (120 tissue/serum; 18 stricture tissue only), 78 had idiopathic strictures, 33 had trauma-related strictures, and 27 had LS-related strictures. BMI, stricture length, and stricture location significantly differed between cohorts (P < .001 for each). The highest BMIs and the longest strictures were observed in the LS cohort. SRPT exposures did not significantly differ between etiology cohorts, with > 60% of each reporting low/mild risk. Stricture inflammation significantly differed between cohorts, with mild to severe inflammation present in 27% of trauma-related strictures, 54% of idiopathic strictures, and 48% of LS strictures (P = .036). Stricture fibrosis did not significantly differ between cohorts (P = .7). Three serum cytokines were significantly higher in patients with strictures compared to stricture-free controls: interleukin-9 (IL-9; P = .001), platelet-derived growth factor-BB (P = .004), and CCL5 (P = .01). No differences were observed in the levels of these cytokines based on stricture etiology. However, IL-9 levels were significantly higher in patients with inflamed strictures than in patients with strictures lacking inflammation (P = .019). Degree of stricture inflammation positively correlated with serum levels of IL-9 (Spearman's rho 0.224, P = .014). CONCLUSIONS The most common aUSD etiology is idiopathic. Though convention has implicated SRPT as causative for idiopathic strictures, here we found that patients with idiopathic strictures had low SRPT rates that were similar to rates in patients with a known stricture etiology. Stricture and stricture-adjacent inflammation in idiopathic stricture were similar to LS strictures, suggesting shared pathophysiologic mechanisms. IL-9, platelet-derived growth factor-BB, and CCL5, which were elevated in patients with strictures, have been implicated in fibrotic conditions elsewhere in the body. Further work will be required to determine if this shared biologic signature represents a potential mechanism for an aUSD predisposition.

Abstract
PURPOSE This study tested the hypothesis that ecological momentary assessment (EMA) of pelvic pain (PP) and urinary urgency (UU) would reveal unique Urologic Chronic Pelvic Pain Syndrome (UCPPS) phenotypes that would be associated with disease specific quality of life (QOL) and illness impact metrics (IIM). MATERIALS AND METHODS A previously validated smart phone app (M-app) was provided to willing Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) participants. M-app notifications were sent 4-times daily for 14 days inquiring about PP and UU severity. A clustering algorithm that accounted for variance placed participants into PP and UU variability? clusters. Associations between clusters and QOL and IIM were then determined. RESULTS A total of 204 participants enrolled in the M-app study (64% female). M-app compliance was high (median 63% of surveys). Cluster analysis revealed k = 3 (high, low, none) PP clusters and k = 2 (high, low) UU clusters. When adjusting for baseline pain severity, high PP variability, but not UU variability, was strongly associated with QOL and IIM; specifically worse mood, worse sleep and higher anxiety. UU and PP clusters were associated with each other (p < 0.0001), but a large percentage (33%) of patients with high PP variability had low UU variability. CONCLUSIONS PP variability is an independent predictor of worse QOL and more severe IIM in UCPPS participants after controlling for baseline pain severity and UU. These findings suggest alternative pain indices, such as pain variability and unpredictability, may be useful adjuncts to traditional measures of worst and average pain when assessing UCPPS treatment responses.

Abstract
OBJECTIVE To review the management of ovarian cancer (OCa) associated hydronephrosis (HN). Specifically, we aim to identify optimal management of HN in the acute setting, predictors of HN resolution, and the role of surgery (tumor debulking/(+/-)ureterolysis/hysterectomy). MATERIALS/METHODS The study cohort included OCa patients managed at our institution from 2004-2019 that developed OCa-associated HN. Initial HN management was recorded as none, retrograde ureteral stent (RUS) or percutaneous nephrostomy tube (PCN). Primary outcomes included (1) HN management failure, (2) HN management complications, and (3) HN resolution. Patient, cancer, and treatment predictors of outcomes were assessed using logistic regression and fine-Gray competing risk models. RESULTS Of 2580 OCa patients, 190 (7.4%) developed HN. HN was treated in 121; 90 (74.4%) with RUS, 31 (25.6%) with PCN. Complication rates were similar between PCN and RUS (83% vs 85.1%; P = .79; all Clavian Grade I/II). Initial HN treatment failure occurred in 28 patients, predicted by renal atrophy (hazard ratios (HR) 3.27, P <.01). HN resolution occurred in only 52 (27%) patients and was predicted by lower International Federation of Gynecology and Obstetrics (FIGO) stage (FIGO III/IV HR 0.42, P <.01) and surgical tumor debulking/ureterolysis (HR 2.83, P = .02). CONCLUSION Resolution of HN associated with malignant obstruction from OCa is rare and is most closely associated with tumor debulking and International Federation of Gynecology and Obstetrics (FIGO) stage. Initial endoscopic treatment modality was not significantly associated with complications or resolution, though RUS failures were slightly more common. Ureteral reconstruction at time of debulking/ureterolysis is potentially underutilized.

Abstract
OBJECTIVE To identify genes that may play a role in urethral stricture and summarize the results of studies that have documented variations in gene expression among individuals with urethral stricture compared to healthy individuals. METHODS A systematic search was conducted in Cochrane, Ovid, Web of Science, and PubMed, limiting the results to articles published between January 1, 2000 and January 30, 2023. Only studies comparing the difference in gene expression between individuals with urethral stricture and healthy individuals utilizing molecular techniques to measure gene expression in blood, urine, or tissue samples were included in this systematic review. Gene network and pathway analyses were performed using Cytoscape software, with input data obtained from our systematic review of differentially expressed genes in urethral stricture. RESULTS Four studies met our criteria for inclusion. The studies used molecular biology methods to quantify gene expression data from specimens. The analysis revealed gene expressions of CXCR3 and NOS2 were downregulated in urethral tissue samples, while TGFB1, UPK3A, and CTGF were upregulated in plasma, urine and urethral tissue samples, respectively, in patients with urethral stricture compared to healthy controls. The analysis demonstrated that the most significant pathways were associated with phosphoinositide 3-kinase (PI3 kinase) and transforming growth factor beta 1/suppressor of mothers against decapentaplegic (TGF-β1/SMAD) signaling pathways. CONCLUSION This systematic review identified gene expression variations in several candidate genes and identified underlying biological pathways associated with urethral stricture. These findings could inform further research and potentially shift treatment and prevention strategies for urethral stricture.

Abstract
BACKGROUND This study updates the American Association for Surgery of Trauma (AAST) Organ Injury Scale (OIS) for renal trauma using evidence-based criteria for bleeding control intervention. METHODS This was a secondary analysis of a multi-center retrospective study including patients with high grade renal trauma from 7 Level-1 trauma centers from 2013-2018. All eligible patients were assigned new renal trauma grades based on revised criteria. The primary outcome used to measure injury severity was intervention for renal bleeding. Secondary outcomes included intervention for urinary extravasation, units of packed red blood cells (PRBCs) transfused within 24 hours, and mortality. To test the revised grading system, we performed mixed effect logistic regression adjusted for multiple baseline demographic and trauma covariates. We determined the area under the receiver-operator curve (AUC) to assess accuracy of predicting bleeding interventions from the revised grading system and compared this to 2018 AAST organ injury scale. RESULTS based on the 2018 OIS grading system, we included 549 patients with AAST Grade III-V injuries and CT scans (III: 52% (n = 284), IV: 45% (n = 249), and V: 3% (n = 16)). Among these patients, 89% experienced blunt injury (n = 491) and 12% (n = 64) underwent intervention for bleeding. After applying the revised grading criteria, 60% (n = 329) of patients were downgraded and 4% (n = 23) were upgraded; 2.8% (n = 7) downgraded from grade V to IV, and 69.5% (n = 173) downgraded from IV to III. The revised renal trauma grading system demonstrated improved predictive ability for bleeding interventions (2018 AUC = 0.805, revised AUC = 0.883; p = 0.001) and number of units of PRBCs transfused. When we removed urinary injury from the revised system, there was no difference in its predictive ability for renal hemorrhage intervention. CONCLUSIONS A revised renal trauma grading system better delineates the need for hemostatic interventions than the current AAST OIS renal trauma grading system. LEVEL OF EVIDENCE II.

Abstract
ABSTRACT No previous works have analyzed whether the order in which surgical teams see patients on morning rounds affects discharge efficiency at teaching hospitals. We obtained perioperative urologic surgery timing data at our academic institution from 2014 to 2019. We limited the analysis to routine postoperative day 1 discharges. Univariate and multivariate analyses were performed to determine whether various hospital and patient factors were associated with discharge timing. We analyzed 1,494 patients. Average discharge order time was 11:22 a.m. and hospital discharge 1:24 p.m. Univariate regression revealed earlier discharge order time for patients seen later in rounds by 4 minutes per sequential room cluster (p = .013) and by 12 minutes per cluster when excluding short-stay patients. Multivariate analysis revealed discharge order placement did not vary significantly by rounding order. However, time of hospital discharge did (p < .001), likely due to speed of discharge in the designated short-stay units. Attending physician was the most consistent predictor in variations of discharge timing, with statistical significance across all measured outcomes. Patients seen later in rounding progression received earlier discharge orders, but this relationship does not remain in multivariate modeling or translate to earlier discharge. These findings have helped guide quality improvement efforts focused on discharge efficiency.

Abstract
Haemorrhagic cystitis (HC) is characterised by persistent haematuria and lower urinary tract symptoms following radiotherapy or chemotherapy. Its pathogenesis is poorly understood but thought to be related to acrolein toxicity following chemotherapy or fibrosis/vascular remodelling after radiotherapy. There is no standard of care for patients with HC, although existing strategies including fulguration, hyperbaric oxygen therapy, botulinum toxin A, and other intravesical therapies have demonstrated short-term efficacy in cohort studies. Novel agents including liposomal tacrolimus are promising targets for further research. This review summarises the incidence and pathogenesis of HC as well as current evidence supporting its different management strategies.

Abstract
OBJECTIVE To describe the characteristics, management, and functional outcomes of patients with synchronous urethral stricture disease (SUSD) utilizing a multi-institutional cohort. METHODS Data were collected and assessed from a prospectively maintained, multi-institutional database. Patients who underwent anterior urethroplasty for urethral stricture disease (USD) were included and stratified by the presence or absence of SUSD. USD location and etiology were classified according to the Trauma and Urologic Reconstruction Network of Surgeons Length, Segment and Etiology Anterior Urethral Stricture Classification System. Anterior urethroplasty techniques were recorded for both strictures. Functional failure was compared between groups. RESULTS One thousand nine hundred eighty-three patients were identified, of whom, 137/1983 (6.9%) had SUSD. The mean primary stricture length for patients with SUSD was 3.5 and 2.6 cm for the secondary stricture. Twelve anterior urethroplasty technique combinations were utilized in treating the 27 different combinations of SUSD. Functional failure was noted in 18/137 (13.1%) patients with SUSD vs 192/1846 (10.4%) patients with solitary USD, P = .3. SUSD was not associated with increased odds of functional failure. S classifications: S1b, P = .003, S2a, P = .001, S2b, P = .01 and S2c, P = .02 and E classifications: E3a, P = .004 and E6, P = .03, were associated with increased odds of functional failure. CONCLUSION Repair of SUSD in a single setting does not increase the risk of functional failure compared to patients with solitary USD. Increasing S classification, S1b through S2c and E classifications E3a and E6 were associated with increased functional failure. This reinforces the importance of the Trauma and Urologic Reconstruction Network of Surgeons Length, Segment and Etiology Anterior Urethral Stricture Classification System as a necessary tool in large-scale multi-institutional analysis when assessing highly heterogenous patient populations.

Importance The Veterans Choice Program (VCP) was implemented in 2014 to help veterans gain broader access to specialized care outside of the Veterans Health Administration (VHA) facilities by providing them with purchased community care (CC). Objective To describe the prevalence and patterns in VCP-funded purchased CC after the implementation of the VCP among veterans with prostate cancer. Design, Setting, and Participants This cohort study used VHA administrative data on veterans with prostate cancer diagnosed between January 1, 2015, and December 31, 2018. These veterans were regular VHA primary care users. Analyses were performed from March to July 2023. Exposures Driving distance (in miles) from residence to nearest VHA tertiary care facility. The location (VHA or purchased CC) in which treatment decisions were made was ascertained by considering 3 factors: (1) location of the diagnostic biopsy, (2) location of most of the postdiagnostic prostate-specific antigen laboratory testing, and (3) location of most of the postdiagnostic urological care encounters. Main Outcomes and Measures The main outcome was receipt of definitive treatment and proportion of purchased CC by treatment type (radical prostatectomy [RP], radiotherapy [RT], or active surveillance) and by distance to nearest VHA tertiary care facility. Quality was evaluated based on receipt of definitive treatment for Gleason grade group 1 prostate cancer (low risk/limited treatment benefit by guidelines). Results The cohort included 45 029 veterans (mean [SD] age, 67.1 [6.9] years) with newly diagnosed prostate cancer; of these patients, 28 866 (64.1%) underwent definitive treatment. Overall, 56.8% of patients received definitive treatment from the purchased CC setting, representing 37.5% of all RP care and 66.7% of all RT care received during the study period. Most patients who received active surveillance management (92.5%) remained within the VHA. Receipt of definitive treatment increased over the study period (from 5830 patients in 2015 to 9304 in 2018), with increased purchased CC for patients living farthest from VHA tertiary care facilities. The likelihood of receiving definitive treatment of Gleason grade group 1 prostate cancer was higher in the purchased CC setting (adjusted relative risk ratio, 1.79; 95% CI, 1.65-1.93). Conclusions and Relevance This cohort study found that the percentage of veterans receiving definitive treatment in VCP-funded purchased CC settings increased significantly over the study period. Increased access, however, may come at the cost of low care quality (overtreatment) for low-risk prostate cancer.

Abstract
PURPOSE/OBJECTIVE(S) Various auto-segmentations, including deep learning auto-segmentation (DLAS), are being increasingly adopted in radiotherapy. A common method to evaluate quality of auto-segmented contours uses thresholds of various quantitative metrics (e.g., dice similarity coefficient (DSC), mean distance to agreement (MDA), etc.) that are often averaged over all contour slices. This method fails to detect contour errors on individual slices, thus, does not reflect the current clinical practice (slice-by-slice evaluation) and the clinical usability (e.g., expected contour editing time). In addition, the use of multi-metrics is generally not easy to interpret. This work aims to develop a novel contour quality classification (CQC) model to evaluate auto-segmented contours based on their clinical applicability. MATERIALS/METHODS The CQC method was designed to classify a contour on a slice into acceptable, minor edit or major edit category, based on the expected editing effort/time. Organ-specific supervised ensemble tree classification models were trained to relate the slice-based quality category with the combination of seven commonly used calculatable quantitative metrics (i.e., DSC, MDA, Hausdorff 95% distance, surface DSC, added path length (APL), slice area and relative APL). The proposed method was demonstrated by training CQC models using DLAS contours of five abdominal organs (i.e., pancreas, duodenum, stomach, and small and large bowels) from 50 MRI sets and evaluating on 20 MRI and 9 CT testing sets. These test datasets were labelled by six individual observers and the consensus labels were generated through majority vote method. The model performance was evaluated using accuracy (acc), and risk rate (RR, the percentage of unacceptable slices mislabeled as acceptable) and compared with inter-observer variation and baseline threshold-based method. RESULTS Compared to the majority vote labels, the obtained CQC models achieved a mean accuracy of 95.8% ([94.5%-99.1%]) and 94.3% ([90.6%-96.9%]), and the mean RR of 0.8% ([0.3%-1.3%]) and 0.7% ([0%-1.1%]) for the MRI and CT testing sets, respectively. The CQC performance was comparable to the inter-observer variation and significantly higher than those from the threshold-based method with single or multiple metrics. The execution time on a typical abdominal dataset (e.g., 70 slices) took less than 3 seconds. Table 1 CQC models performance for different organs CONCLUSION: The proposed CQC model can classify the quality of a contour slice with high accuracy. This slice-based single-output evaluation method better reflects the current clinical practice and may be used to evaluate/compare performance of DLAS on any image modality, facilitating its clinical implementation and quality assurance.

Abstract
PURPOSE/OBJECTIVE(S) Advanced radiation treatment planning is a complex, multi-step process beginning with image acquisition and using these images to contour radiation targets and organs at risk prior to radiation treatment planning. Contouring is a time-consuming process. Unfortunately, few radiation oncologists have dedicated contouring time allocated in their daily schedule. Also, across radiation practices there is variability amongst dosimetrists, physicists, and physicians in the assignment of contouring responsibilities. The goal of this survey was to explore how the multi-disciplinary task of contouring for treatment planning is managed across radiation oncology practices and its impact on quality of life (QOL) amongst dosimetrists, physicists, and physicians. MATERIALS/METHODS A comprehensive 19-question Qualtrics survey was created evaluating all aspects of contouring and radiation treatment planning and its impact on QOL. The survey was distributed through Twitter, AAMD, a Medical Physics Journal, as well as directly to radiation oncology practices. Survey responses were summarized as proportions and associations tested using Fisher's exact test. RESULTS Physicians spent more time completing job responsibilities after work than dosimetrists and physicists, with an average of 6.22 hours (range 0-20) in comparison to 4.16 (0-30) for dosimetrists and 1.55 (0-12) for physicists (p-value 0.001). Physicians on average spent more time contouring on weekends with 1.81 hours (0-10) in comparison to 0.54 (0-10+) for dosimetrists and 0.31 (0-10) for physicists (p-value <0.001). When considering QOL and time spent after work, more respondents agreed there was a negative impact on QOL with increased responsibilities outside work hours (p-value <0.001). On average, respondents performed anywhere from 0 to 85 weekly radiotherapy simulations. The average time delay between simulation and when the imaging datasets are ready for contours was 1.31 days (1-4). 84 respondents signified there is no repercussion for delayed contour plans as planning is fast-tracked to meet the deadline, while 52 respondents signified postponement of radiotherapy start date. Time spent contouring after work hours (p-value 0.148) and on the weekend (p-value 0.403) were similar for both academic and private centers. Similarly, there was no difference in time of days of completion of 3D Conformal Radiation Therapy (p-value 0.551), Intensity Modulated Radiation Therapy (p-value 0.222), or Stereotactic Body Radiation Therapy (p-value 0.551) from academic versus private centers. CONCLUSION We present new insight into the amount of time spent in radiation oncology practices by dosimetrists, physicists, and physicians, performing the critical task of contouring for radiation treatment planning and its impact on QOL. These results can be used to guide decisions in the clinic for allocation of radiation treatment planning time and manpower.

Abstract
OBJECTIVE To clinically validate a previously developed adult-acquired buried penis (AABP) classification system that is based on a standardized preoperative physical examination that subtypes patients by their penile skin/escutcheon complex (P), abdominal pannus (A), and scrotal skin (S). METHODS The Trauma and Urologic Reconstruction Network of Surgeons (TURNS) database was used to create an AABP cohort. Patients were retrospectively classified using the previously described PAS classification system. The frequency of subtypes, surgical methods utilized for AABP repair, and correlations between PAS classification and surgery subtypes were analyzed. RESULTS The final cohort consisted of 101 patients from 10 institutions. Interrater reliability between two reviewers was excellent (κ = 0.95). The most common subtypes were P2c (contributory escutcheon+insufficient penile skin; 27%) and P2a (contributory escutcheon+sufficient penile skin; 21%) for penile subtypes, A0 (no pannus; 41%) and A1 (noncontributory pannus; 39%) for abdominal subtypes, and S0 (normal scrotal skin with preserved scrotal sulcus; 71%) for scrotal subtypes. AABP repair procedures included escutcheonectomy (n = 59, 55%), scrotoplasty (n = 51, 48%), split-thickness skin grafting (n = 50, 47%), penile skin excision (n = 47, 44%) and panniculectomy (n = 7, 7%). P, A, and S subtypes were strongly associated with specific AABP surgical techniques. CONCLUSION The PAS classification schema adequately describes AABP heterogeneity, is reproducible among observers, and correlates well with AABP surgery types. Future work will focus on how PAS subtypes affect both surgical and patient-centered outcomes.

Abstract
PURPOSE/OBJECTIVE(S) Patients with medically inoperable endometrial cancer (MIEC) are curable with brachytherapy (BT)-based treatment yet have competing comorbidities making definitive treatment challenging. MRI demonstrates superior soft tissue anatomy and target volume delineation but with limited data in MIEC patients. We aim to report disease and toxicity outcomes with MRI-based BT and identify dose-volume relationships for toxicities in the treatment of MIEC patients treated with MRI-based BT. MATERIALS/METHODS We conducted a retrospective multi-institutional analysis of MIEC patients undergoing definitive MRI-based BT (+/- EBRT). MRI-based BT was delivered with the applicator in situ or coregistered to a planning CT. We identified patient, tumor, and dosimetric factors associated with disease and toxicity outcomes. Kaplan-Meier method was used for survival estimates. Log rank test and Cox proportional hazards were used for univariate and multivariate analyses, respectively. T-test was used for dose-volume toxicity analysis. RESULTS A total of 120 patients were included with a median follow up of 28.0 months. Median age was 68.5 years. ECOG PS was 0-1 in 70%. Clinical stage I was 83.3% and II-IV, 16.7%. Most patients (91.7%) were node negative. Endometrioid and high risk histologies comprised 83.3%, and 16.7%, respectively. EBRT + BT was delivered in 97 patients (80.8%) and BT alone in 23 patients (19.2%). Chemotherapy or hormonal therapy was delivered during treatment in 10 (8.3%) and 11 (9.2%) patients, respectively. Estimated 3-year freedom from local, nodal, and distant recurrence were 88.0%, 96.0%, and 89.1% respectively. Estimated 3-year PFS and OS were 60.9% and 62.9%, respectively. On UVA, older age, PS ≥2, high risk histology, higher grade, and larger GTV at BT were significant (p<0.1). On MVA, older age, higher grade, and larger GTV at BT (p<0.05) predicted for inferior PFS. Fifteen late grade ≥3 toxicities were experienced in 14 (11.6%) patients, 13 of whom received EBRT and BT and 1 who received BT alone. Grade ≥3 toxicities were rectal (2, 1.7%), sigmoid (8, 6.7%), bowel (1, 0.8%), bladder (3, 2.5%), and osseous (1, 0.8%). EBRT was delivered in 7 of 8 sigmoid toxicities. Median sigmoid doses (EQD2a/b = 3Gy) for patients with and without late grade ≥3 sigmoid toxicity were 69.6 Gy and 64.3 Gy, respectively (p = 0.009). CONCLUSION MRI-based BT for MIEC patients results in high rates of local control and favorable rates of late grade ≥3 morbidity. Older age, higher grade, and larger GTV at BT predicted for poorer PFS. Sigmoid colon was the predominant organ at risk for grade ≥3 toxicity with a dose -volume relationship observed. Attention to the location of the sigmoid throughout the treatment course may add insight into its predilection for risk. Future work will include additional institutions and dose-volume relationships of target volumes and normal tissues for further disease control and toxicity analysis.

Abstract
PURPOSE/OBJECTIVE(S) Neoadjuvant treatment for patients with localized pancreatic adenocarcinoma (PDAC) has improved survival duration. As survival increases, local disease control becomes even more important. We sought to understand the patterns of locoregional recurrence following total neoadjuvant therapy (TNT) and determine the impact of treatment volumes on recurrence. MATERIALS/METHODS Patients with PDAC managed with neoadjuvant chemotherapy and chemoradiation (TNT) followed by surgery who developed an isolated locoregional or simultaneously locoregional and distant recurrence were identified. Locoregional recurrences were individually contoured utilizing commercially available software. When available, original neoadjuvant dose distributions were registered to the scans on which the locoregional recurrences were contoured. Recurrences where then classified as in-field (> 95% of prescription dose), marginal (50-95% of prescription dose), or out of field (< 50% of prescription dose). Target volumes were created using four commonly utilized PDAC contouring guidelines to characterize the relationship of the local recurrence to the RT dose distribution. RESULTS Of 474 patients treated with TNT and surgery, 80 (17%) patients developed a locoregional recurrence with or without distant recurrence, visible on diagnostic imaging. Of the 80 patients, 56 (70%) had tumors in the pancreatic head; 46 (57.5%) were borderline resectable, 23 (28.8%) locally advanced, and 11 (13.6%) resectable. The most common initial neoadjuvant therapies were FOLFIRINOX (57.5%) and gemcitabine/nab-paclitaxel (18.8%). Chemoradiation included concurrent gemcitabine (47.5%) or 5-fluorouracil (26.3%). RT dose distributions were available for 38 patients; 22 (57.9%) had in-field failures, 9 (23.7%) marginal failures, and 7 (18.4%) out of field failures. Each published contouring atlas covered a relatively low percentage of recurrences, which are summarized in Table 1. Regions at particularly high likelihood of recurrence that were under covered on existing atlases included: aortic-diaphragmic junction, retro-pancreatic duodenal nodal basin, and the region to the right of the superior mesenteric artery (SMA). CONCLUSION We present the largest series (to our knowledge) of mapped locoregional recurrences for patients being treated with TNT in PDAC. These recurrences differ substantially from established atlases and highlight anatomical regions of highest priority for RT coverage. A novel visual contouring volume highlighting these regions will be presented which will strive to advance the use of RT in the TNT setting.

Abstract
Background We evaluated the prevalence, distribution, and specialist to population ratio of male and female reconstruction and andrology/prosthetics faculty within United States urologic training programs. Our objective was to help determine the current need/demand for reconstructive fellowship trained faculty for necessary clinical exposure during residency in the midst of a nationwide residency expansion. Methods All non-military urology residency programs were evaluated. Programs were sorted into their American Urologic Association Sections and websites were analyzed for evidence of fellowship training and/or clinical expertise/interest: (I) male genitourinary reconstruction (MGR); (II) female genitourinary reconstruction (FGR) and (III) infertility/andrology/men's health (AMH). The 2020 US Census data was used to determine specialist to population ratios by sections. Results Of 137 evaluated programs, FGR had the highest percentage of fellowship-trained faculty (76%) followed by AMH (66%) and MGR (61%). Clinical/surgical interest was noted in pelvic organ prolapse (88%), inflatable penile prosthesis (79%) and urethral stricture disease (75%). Over 10% of training programs had two or more faculty with MGR, FGR and AMH fellowship training. Significant geographic variation amongst academic programs exists with the South and Southeastern parts of the US being relatively underserved, both in percentage of programs with fellowship-trained faculty, and by faculty per 1,000,000 inhabitants. Conclusions The majority of US urology residencies have faculty with fellowship training and/or stated clinical interest in MGR, FGR and AMH. Still, many programs remain without these faculty while others have two or more in their respective fields. The geographic trends noted here have both educational and recruitment significance.

Abstract
OBJECTIVE To study the prevalence and management of shattered kidney and to evaluate if the new description of "loss of identifiable renal anatomy" in the 2018 American Association for the Surgery of Trauma (AAST) organ injury scale (OIS) would improve the ability to predict bleeding control interventions. METHODS We used high-grade renal trauma data from 21 Level-1 trauma centers from 2013 to 2018. Initial CT scans were reviewed to identify shattered kidneys, defined as a kidney having ≥3 parenchymal fragments displaced by blood or fluid on cross-sectional imaging. We further categorized patients with shattered kidney in two models based on loss of identifiable renal parenchymal anatomy and presence or absence of vascular contrast extravasation (VCE). Bleeding interventions were compared between the groups. RESULTS From 861 high-grade renal trauma patients, 41 (4.8%) had shattered kidney injury. 25 (61%) underwent a bleeding control intervention including 18 (43.9%) nephrectomies and 11 (26.8%) angioembolizations. 18 (41%) had shattered kidney with "loss of identifiable parenchymal renal anatomy" per 2018 AAST OIS (model-1). 28 (68.3%) had concurrent VCE (model-2). Model-2 had a statistically significant improvement in area under the curve over model-1 in predicting bleeding interventions (0.75 vs 0.72; P = .01). CONCLUSION Shattered kidney is associated with high rates of active bleeding, urinary extravasation, and interventions including nephrectomy. The definition of shattered kidney is vague and subjective and our definition might be simpler and more reproducible. Loss of identifiable renal anatomy per the 2018 AAST OIS did not provide better distinction for bleeding control interventions over presence of VCE.

Abstract
PURPOSE To investigate management trends for American Association for the Surgery of Trauma (AAST) grade V renal trauma with focus on non-operative management. METHODS We used prospectively collected data as part of the Multi-institutional Genito-Urinary Trauma Study (MiGUTS). We included patients with grade V renal trauma according to the AAST Injury Scoring Scale 2018 update. All cases submitted by participating centers with radiology images available were independently reviewed to confirm renal trauma grade. Management was classified as expectant, conservative (minimally invasive, endoscopic or percutaneous procedures), or operative (renal-related surgery). RESULTS Eighty patients were included, 25 of whom had complete imaging and had independent confirmation of AAST grade V renal trauma. Median age was 35 years (Interquartile range (IQR) 25-50) and 23 (92%) had blunt trauma. Ten patients (40%) were managed operatively with nephrectomy. Conservative management was used in nine patients (36%) of which six received angioembolization and three had a stent or drainage tube placed. Expectant management was followed in six (24%) patients. Transfusion requirements were progressively higher with groups requiring more aggressive treatment, and injury characteristics differed significantly across management groups in terms of hematoma size and laceration size. Vascular contrast extravasation was more likely in operatively managed patients though a statistically significant association was not found. CONCLUSION Successful use of nonoperative management for grade V injuries is used for a substantial subset of patients. Lower transfusion requirement and less severe injury radiologic phenotype appear to be important characteristics delineating this group.

Abstract
OBJECTIVE To determine if imaging with a thermal infrared camera might aid clinicians with diagnosis of equivocal necrotizing soft tissue infections of the genitalia (NSTIG) cases and help surgeons when determining appropriate surgical resection margins. MATERIALS/METHODS For twelve months at a single tertiary academic hospital, sequential patients already undergoing exploration for acute scrotum had preoperative photography with an infrared camera (FLIR C5). We compared infrared and standard preoperative photography with operative reports and postoperative photography to investigate if infrared photography corresponded with operative findings in severe scrotal infections - specifically the viability of the skin and the ultimate surgical resection margins. RESULTS A total of 16 patients were included. The pre-operative infrared photos directly correlated with resection margins in 13 of 16 (81%) patients. Notably, areas with a relatively lower (cooler) infrared intensity corresponded well to both visibly necrotic tissue when discrete and areas with large underlying fluid collections. Diffuse warm signal relative to surrounding skin correlated with cellulitis and viable skin. CONCLUSIONS In this observational study, infrared photography corresponded well with physical exam and operative findings. There may be a role for augmented temperature photography in the diagnosis and triage of scrotal infections. More research with standardized temperature gating of infrared signal and controls with normal or nonacute scrotums are needed to elucidate the clinical utility for infrared photograph.

Abstract
PURPOSE The purpose of this paper was to investigate patterns of health care utilization leading up to diagnosis of necrotizing soft tissue infections of the genitalia and to identify risk factors associated with potential diagnostic delay. MATERIALS AND METHODS IBM MarketScan Research Databases (2001-2020) were used to identify index cases of necrotizing soft tissue infections of the genitalia. We identified health care visits for symptomatically similar diagnoses (eg, penile swelling, cellulitis) that occurred prior to necrotizing soft tissue infections of the genitalia diagnosis. A change-point analysis identified the window before diagnosis where diagnostic opportunities first appeared. A simulation model estimated the likelihood symptomatically similar diagnosis visits represented a missed opportunity for earlier diagnosis. Patient and provider characteristics were evaluated for their associations with delay. RESULTS We identified 8,098 patients with necrotizing soft tissue infections of the genitalia, in which 4,032 (50%) had a symptomatically similar diagnosis visit in the 21-day diagnostic window, most commonly for "non-infectious urologic abnormalities" (eg, genital swelling; 64%): 46% received antibiotics; 16% saw a urologist. Models estimated that 5,096 of the symptomatically similar diagnosis visits (63%) represented diagnostic delay (mean duration 6.2 days; mean missed opportunities 1.8). Risk factors for delay included urinary tract infection history (OR 2.1) and morbid obesity (OR 1.6). Visits to more than 1 health care provider/location in a 24-hour period significantly decreased delay risk. CONCLUSIONS Nearly 50% of insured patients who undergo debridement for, or die from, necrotizing soft tissue infections of the genitalia will present to a medical provider with a symptomatically similar diagnosis suggestive of early disease development. Many of these visits likely represent diagnostic delay. Efforts to minimize logistic and cognitive biases in this rare condition may lead to improved outcomes if they lead to earlier interventions.

Abstract
OBJECTIVE To evaluate the efficacy of early necrotizing soft-tissue infections of the genitalia (NSTIG) component separation, primary wound closure (CSC). We hypothesized that early CSC would be safe, decrease the need for split-thickness skin grafting (STSG) and decrease wound convalescence time. MATERIALS/METHODS Management of consecutive NSTIG patients from a single institution were evaluated. Three cohorts emerged: 1) those managed/closed by a reconstructive urologist (URO) using CSC principles (wide genital tissue mobilization with primary closure, when possible, +/- STSG), 2) those managed/closed by the general surgery/burn service, and 3) those managed conservatively with secondary closure. Total NSTIG anatomic extent (AE) was determined by assessing involvement of the penis, scrotum, perineum and suprapubic region, and ranged from 1 (<50% involvement of one area) to 8 (>50% involvement in all 4 areas). RESULTS Of 84 FG patients meeting study criteria, 48 (57%) were closed primarily and 36 were left to heal by secondary intention. AE was greatest in patients managed by general surgery/burn service (4.5 ± 1.5), followed by URO (2.7 ± 1.8) and secondary intention cases (1.3 ± 0.5). Secondary procedure rates were similar between closure/non-closure cohorts (6.3% v 11%; P = 0.67). STSG use was predicted by wound size (though not time to closure)-specifically with suprapubic and/or penile wounds of >50% involvement. Wound convalescence time decreased by 64% when wounds were closed versus left open, controlling for AE. CONCLUSION Early, same-admission primary closure of stable NSTIG wounds is safe and decreases wound convalescence time by over 60%.

Abstract
OBJECTIVE Suprapubic tubes (SPT) are a vital tool in the management of complex urologic voiding conditions. There are numerous methods of SPT placement, each with pros/cons: peel-away kits are easy to place, but often have small caliber SPTs i.e., 12 or 14 Fr, prone to kinking, that require serial upsizing to achieve the desired caliber; open SPT placements permit an initial large caliber SPT but are more invasive, particularly in obese patients. This video demonstrates a minimally invasive technique for SPT placement in patients with preserved urethral access to the bladder that safely allows for initial, precise placement of large caliber (>20F) catheters using the Nephromax® nephrostomy balloon/sheath (NBS-SPT). METHODS Technique: A 6" 17G Tuohy® spinal needle is placed percutaneously 3 cm above the pubis (generally in the abdominal crease), 1-2 cm off midline towards the side the patient prefers to keep the drainage bag. The needle is angled to enter the bladder dome in the midline, which is visualized cystoscopically with a full bladder. The angling will allow the catheter to lie flat and decrease kinking. The stylette is removed and a stiff wire is advanced. A 2cm horizontal skin incision is made. A 24 Fr NBS is advanced into the bladder under vision and inflated to 18 ATM. The balloon is then deflated/removed and the SPT is passed through the sheath into the bladder. Once inflated, the sheath removed and the SPT is secured to the skin. STUDY A 10-year retrospective review of NBS-SPT placements at a single institution was performed, analyzing patient characteristics, surgical details, and surgical outcomes. RESULTS NBS-SPT was attempted 65 times over the study period. The most common indications included acquired/congenital neurogenic bladder (48%) and urinary retention (25%). A simultaneous additional procedure (e.g. cytolitholapaxy, bladder neck incision) was performed in 31% of NBS-SPTs. Median BMI was 29.5 (IQR: 25-33.9) and 34% had prior abdominal procedures. Median operative time (NBS-SPT only) was 16 minutes (IQR 14-20). All procedures were successful in placing a catheter 20F. 30-day Clavien I/II complication rate was 18% (hematuria n=3; cellulitis n=4; early SPT exchange for clogging n=5); A Clavien IIIb complication occurred in one patient with hematuria requiring fulguration. First SPT exchange in clinic was successful in 95%, with two patients requiring replacement under anesthesia. CONCLUSION NBS-SPT is a safe and efficient minimally invasive technique for initial, precise placement of large caliber SPT in patients with urethral bladder access.

Abstract
OBJECTIVE To identify predictors of hydronephrosis (HN) resolution and HN treatment failure. HN is a common comorbid condition with cervical cancer (CCa). Treatments for CCa continue to improve and long-term management strategies of HN are becoming increasingly necessary. METHODS A query of a single hospital (2004 - 2019) ICD-9 and CPT codes was made to develop a cohort of CCa patients with HN. A retrospective review was performed. The effects of patient, renal/HN, and cancer covariates on time to HN treatment failure, treatment complications and time to HN resolution were evaluated using logistic regression and competing risk Cox regression models. RESULTS Of the 1670 women treated for CCa during the study period, 179 (10.7%) developed HN (n = 72 (40%) bilateral), 78 (44%) at time of CCa diagnosis and 101 (56%) as a result of treatment, of which 145 (81%) underwent initial treatment with a PCN (n = 77, 53%) or US (n = 68, 47%). Complication rates were similar between PCN (56%) and US (61%) when adjusting for treatment time. Initial treatment failure was more likely with US vs PCN (HR 3.2, P <0.01). HN resolution (n = 32, 22%) without reconstruction was predicted by HN concurrent with CCa diagnosis (HR 3.1, P <0.01) and bilateral HN (HR 0.2, P <0.01). CONCLUSION CCa associated HN has a resolution rate of only 19% at 12 months. Those presenting with HN after CCa treatment are less likely to resolve without reconstruction. PCN and US have similar complication rates but initial US placement has a nearly three times increased risk of failing than PCN.

BACKGROUND Refractory vesicourethral anastomotic stenosis (VUAS) after radical prostatectomy poses challenges distinct from bladder neck contracture, due to close proximity to the sphincter mechanism. Open reconstruction is technically demanding, risking de novo stress urinary incontinence (SUI) or recurrence. OBJECTIVE To demonstrate patency and continence outcomes of robotic-assisted VUAS repair. DESIGN, SETTING AND PARTICIPANTS Patients with VUAS underwent robotic-assisted reconstruction from 2015 to 2020 in the Trauma and Urologic Reconstructive Network of Surgeons (TURNS) consortium of institutions. The minimum postoperative follow-up was 3 mo. SURGICAL PROCEDURE The space of Retzius is dissected and fibrotic tissue at the vesicourethral anastomosis is excised. Reconstruction is performed with either a primary anastomotic or an anterior bladder flap-based technique. MEASUREMENTS Patency was defined as either the passage of a 17 French flexible cystoscope or a peak flow on uroflowmetry of >15 ml/s. De novo SUI was defined as either more than one pad per day or need for operative intervention. RESULTS AND LIMITATIONS A total of 32 patients met the criteria, of whom 16 (50%) had a history of pelvic radiation. Intraoperatively, 15 (47%) patients had obliterative VUAS. The median length of hospital stay was 1 d. At a median follow-up of 12 mo, 24 (75%) patients had patent repairs and 26 (81%) were voiding per urethra. Of five men with 30-d complications, four were resolved conservatively (catheter obstruction and ileus). In eight patients, recurrent stenoses were managed with redo robotic reconstruction (in two), endoscopically (in four), or catheterization (in two). Of 13 patients without preexisting SUI, 11 (85%) remained continent at last follow-up. No patients underwent urinary diversion. CONCLUSIONS Robotic-assisted VUAS reconstruction is a viable and successful management option for refractory anastomotic stenosis following radical prostatectomy. The robotic transabdominal approach demonstrates high patency and continence rates. PATIENT SUMMARY We studied the outcomes of robotic-assisted repair for vesicourethral anastomotic stenosis. Most patients, after the procedure, were able to void per urethra and preserve existing continence.

Abstract
OBJECTIVE To determine the attitudes and education regarding surgical castration in men receiving androgen deprivation therapy (ADT) for metastatic prostate cancer (mCaP). METHODS We identified 142 patients receiving ADT for mCaP at our institution without prior orchiectomy who were then sent 2 surveys via mail: (1) A questionnaire to assess knowledge and understanding of ADT treatment alternatives and (2) the functional assessment of cancer therapy - prostate (FACT-P) questionnaire which determines health-related quality of life (HRQOL). Two cohorts were created based on the answer to "would you be interested in surgical orchiectomy?" and demographic, CaP and HRQOL were compared between the surgical castration yes (SC+) and surgical castration no (SC-) cohorts. A second analysis identified predictors of worse HRQOL. RESULTS Of 68 (47.9%) patients that responded to the survey, only 39 (59.1%) recalled a discussion regarding treatment alternatives to ADT and only 22 (33.3%) recalled a discussion regarding orchiectomy. There were 24 (40.0%) patients that stated interest in undergoing orchiectomy (SC+) as an alternative to ADT with the only independent risk factor being "…bother from the number of clinical appointments required for ADT…" Patients most bothered by side effects and cosmetic changes associated with ADT reported lower HRQOL scores on the FACT-P. CONCLUSIONS Few men on ADT knew about surgical alternatives, implying that educational deficits may be a significant factor in the decline in the utilization of orchiectomy. Changes in healthcare economics, utilization and delivery brought on by a global pandemic should warrant a fresh look at the use of surgical castration.

Abstract
Abstract
Purpose: This study aimed to compare the utilization rates of three organ resection surgeries, predominantly indicated for the treatment of cancer, in the US, Canada, and Australia, and compare rates between residents of lower- and higher-income neighborhoods.
Methods: We used population-based administrative data to identify all adults aged ≥18 years hospitalized for pancreatectomy (PX), radical prostatectomy (RP) and nephrectomy (NX) between 2011-2016 (New York, USA), 2011-2018 (Ontario, Canada), and 2013-2018 (New South Wales, Australia). We linked each patient's zip-code of residence to 2016 census data to ascertain neighborhood income. We compared utilization rates for each procedure in each jurisdiction in aggregate and by neighborhood income quintile. Primary outcomes were: 1) each jurisdictions' per-capita overall, age-, and sex-standardized utilization rates for each procedure; and 2) utilization rates amongst residents of lower- and higher-income neighborhoods.
Results: Sociodemographics were similar across jurisdictions; patients in New South Wales were older for all procedures. New York hospitals were significantly likelier to perform each of the three procedures compared to Ontario and New South Wales (all P<0.001); New York and New South Wales hospitals tended to have lower volumes than Ontario hospitals. Overall utilization rate was highest in New York for NX (28.93 procedures per-100,000 per-year) while New South Wales had the highest utilization of PX (6.94) and RP (94.37); overall utilization of all three procedures was lowest in Ontario (PX 6.18; RP 49.24; NX 21.40; all P<0.001). Utilization of PX and NX was significantly higher for men than women in all jurisdictions (all P<0.05). Utilization of all three procedures increased until age 70-79, before declining at age ≥80 (all P<0.001). With the exception of NX in Ontario, residents of lowest income neighborhoods (quintile 1 [Q1]) had lower surgical utilization rates than residents of highest income neighborhoods (quintile 5 [Q5]). The Q5-Q1 utilization rate difference was largest in New South Wales for PX and RP (Q5-Q1 PX +4.65 procedures per-100,000 per-year; RP +73.46; NX +6.23), largest in New York for NX and smallest for RP (PX +3.05; RP +19.70; NX +8.43) and smallest in Ontario for PX and NX (PX +1.15; RP +27.94; NX -1.10) (all P<0.05).
Conclusions: Utilization rates of PX, RP, and NX were significantly higher in New York and New South Wales than in Ontario. Rich-poor surgical utilization differences were significantly larger in New York and New South Wales and significantly smaller in Ontario. These findings suggest that income-based disparities are larger in US and Australian jurisdictions than those Canadian, and highlight the possible trade-offs of equity and access in cancer care of different countries.

Abstract
Neurofibromatosis 1 is a relatively rare genetic disease characterized by widespread neurofibromas originating from the peripheral nervous system. Most growths are benign, but some carry a risk of transformation to malignant peripheral nerve sheath tumors. Although these growths can be found anywhere in the body, they are rarely found in the male external genitalia. This report discusses a case of a 25-year-old male patient with neurofibromatosis 1 presenting with a scrotal mass found to have a very large para-testicular intra-scrotal malignant peripheral nerve sheath tumor that required testicle-sparing radical penectomy.

Abstract
Background To evaluate erectile and sexual function after pelvic fracture urethral injury (PFUI) by performing a retrospective review of a large multi-center database. We hypothesized that most men will have erectile dysfunction (ED) and poor sexual function following PFUI, which will remain after posterior urethroplasty. Methods Using the Trauma and Urologic Reconstructive Networks of Surgeons (TURNS) database, we identified PFUI patients undergoing posterior urethroplasty. We excluded patients with incomplete demographic, surgical and/or questionnaire data. Sexual Health Inventory of Men (SHIM), Male Sexual Health Questionnaire (MSHQ), and subjective changes in penile curvature were collected before urethroplasty surgery and at follow-up. We performed descriptive statistics for erectile and ejaculatory function using STATA v12. Results We identified 92 men meeting inclusion criteria; median age was 41.7 years and BMI was 26.5. The mechanism of injury was blunt in all patients, and average distraction defect length was 2.3 cm (SD 1.0 cm). In the 38 patients who completed both pre and post-operative SHIM questionnaires, the mean SHIM score was 10.5 (SD 7.0), with 63% having severe ED (SHIM <12). The median follow-up was 5.6 months and the mean post-operative SHIM was 9.3 (SD 6.5), with 68% having severe ED. The mean change in SHIM score was −1.18 (SD 6.29) with 6 (16%) patients reporting de novo ED (≥5 point decrease in score). Of the men with pre-operative MSHQ data, 46/74 (62.1%) had difficulty with ejaculation, 25/35 (71%) had change in penile length, and 6/33 (18%) reported penile curvature. In men with post-operative MSHQ, 19/44 (43%) expressed difficulty with ejaculation, 23/32 (72%) had change in penile length, and 9/33 (27%) reported penile curvature. Conclusions There is a high rate of severe ED, both following PFUI and remaining after posterior urethroplasty. Additionally, rates of ejaculatory difficulty and patient perceived changes in penile length and curvature underscore the complex nature of the impact of these injuries on sexual function beyond simple erectile function.

Abstract
Importance Few studies have compared surgical utilization between countries or how rates may differ according to patients' socioeconomic status. Objective To compare population-level utilization of 3 common nonemergent surgical procedures in New York State (US), Ontario (Canada), and New South Wales (Australia) and how utilization differs for residents of lower- and higher-income neighborhoods. Design, Setting, and Participants This cohort study included all adults aged 18 years and older who were hospitalized for pancreatectomy, radical prostatectomy, or nephrectomy between 2011 and 2016 in New York, between 2011 and 2018 in Ontario, and between 2013 and 2018 in New South Wales. Each patient's address of residence was linked to 2016 census data to ascertain neighborhood income. Data were analyzed from August 2019 to November 2020. Main Outcomes and Measures Primary outcomes were (1) each jurisdiction's per capita age- and sex-standardized utilization rates (procedures per 100 000 residents per year) for each surgery and (2) utilization rates among residents of lower- and higher-income neighborhoods. Results This study included 115 428 surgical patients (25 780 [22.3%] women); 5717, 21 752, and 24 617 patients in New York were hospitalized for pancreatectomy, radical prostatectomy, and nephrectomy, respectively; 4929, 19 125, and 16 916 patients in Ontario, respectively; and 2069, 13 499, and 6804 patients in New South Wales, respectively. Patients in New South Wales were older for all procedures (eg, radical prostatectomy, mean [SD] age in New South Wales, 64.8 [7.3] years; in New York, 62.7 [8.4] years; in Ontario, 62.8 [6.7] years; P < .001); patients in New York were more likely than those in other locations to be women for pancreatectomy (New York: 2926 [51.2%]; Ontario: 2372 [48.1%]; New South Wales, 1003 [48.5%]; P = .004) and nephrectomy (New York: 10 645 [43.2%]; Ontario: 6529 [38.6%]; 2605 [38.3%]; P < .001). With the exception of nephrectomy in Ontario, there was a higher annual utilization rate for all procedures in all jurisdictions among patients residing in affluent neighborhoods (quintile 5) compared with poorer neighborhoods (quintile 1). This difference was largest in New South Wales for pancreatectomy (4.65 additional procedures per 100 000 residents [SE, 0.28]; P < .001) and radical prostatectomy (73.46 additional procedures per 100 000 residents [SE, 1.20]; P < .001); largest in New York for nephrectomy (8.43 additional procedures per 100 000 residents [SE, 0.85]; P < .001) and smallest in New York for radical prostatectomy (19.70 additional procedures per 100 000 residents [SE, 2.63]; P < .001); and smallest in Ontario for pancreatectomy (1.15 additional procedures per 100 000 residents [SE, 0.28]; P < .001) and nephrectomy (-1.10 additional procedures per 100 000 residents [SE, 0.52]; P < .001). New York had the highest utilization of nephrectomy (28.93 procedures per 100 000 residents per year [SE, 0.18]) and New South Wales for had the highest utilization of pancreatectomy and radical prostatectomy (6.94 procedures per 100 000 residents per year [SE, 0.15] and 94.37 procedures per 100 000 residents per year [SE, 0.81], respectively; all P < .001). Utilization was lowest in Ontario for all procedures (pancreatectomy, 6.18 procedures per 100 000 residents per year [SE, 0.09]; radical prostatectomy, 49.24 procedures per 100 000 residents per year [SE, 0.36]; nephrectomy, 21.40 procedures per 100 000 residents per year [SE, 0.16]; all P < .001). Conclusions and Relevance In this study, New York and New South Wales had higher per capita surgical utilization and larger neighborhood income-utilization gradients than Ontario. These findings suggest that income-based disparities are larger in the United States and Australia and smaller in Canada and highlight trade-offs inherent in the health care systems of different countries.

Abstract
Abstract
Background: Few studies have compared surgical oncology utilization between countries or how rates may differ according to patients’ socioeconomic status. This study aimed to compare the utilization rates of three organ resection surgeries predominantly indicated for the treatment of cancer in three jurisdictions in the US, Canada, and Australia, and compare surgical utilization rates between residents of lower- and higher-income neighborhoods. Methods: We used population-based administrative data to identify all adults aged ≥18 years hospitalized for pancreatectomy (PX), radical prostatectomy (RP) and nephrectomy (NX) between 2011-2016 (New York, USA), 2011-2018 (Ontario, Canada), and 2013-2018 (New South Wales, Australia). We linked each patient’s zip-code of residence to 2016 census data to ascertain neighborhood income. We compared utilization rates for each procedure in each jurisdiction in aggregate and by neighborhood income quintile. The primary outcomes were: 1) each jurisdictions’ per-capita overall, age-, and sex-standardized utilization rates for each procedure; and 2) utilization rates amongst residents of lower- and higher-income neighborhoods. Results: Sociodemographics were generally similar across jurisdictions, though patients in New South Wales were slightly older for all procedures. Hospitals in New York were significantly more likely to perform each of the three procedures compared to Ontario and New South Wales (all P<0.001), while New York and New South Wales tended to have more low-volume hospitals relative to Ontario. Overall utilization rate was highest in New York for NX (28.93 procedures per-100,000 per-year) while New South Wales had highest utilization of PX and RP (6.94 and 94.37, respectively); overall utilization of all three procedures was lowest in Ontario (PX 6.18; RP 49.24; NX 21.40; all P<.001). Utilization of PX and NX was significantly higher for men than women in all jurisdictions (all P<0.05). Utilization of all three procedures increased until age 70-79, before declining at age ≥80 (all P<0.001). With the exception of NX in Ontario, residents of lowest income neighbourhoods (quintile 1 [Q1]) had lower surgical utilization rates than residents of highest income neighbourhoods (quintile 5 [Q5]). The Q5-Q1 utilization rate difference was largest in New South Wales for PX and RP (PX +4.65 procedures per-100,000 per-year for Q5 vs Q1; RP +73.46; NX +6.23), largest in New York for NX and smallest for RP (PX +3.05; RP +19.70; NX +8.43) and smallest in Ontario for PX and NX (PX +1.15; RP +27.94; NX -1.10) (all P<0.05). Conclusions: Utilization rates of PX, RP, and NX were significantly higher in New York and New South Wales than in Ontario. Rich-poor surgical utilization differences were significantly larger in New York and New South Wales and significantly smaller in Ontario. These findings suggest that income-based disparities are larger in jurisdictions in the US and Australia and smaller in Canada, and highlight the possible trade-offs of equity and access in healthcare systems of different countries.

Abstract
OBJECTIVE To evaluate the outcomes of excision and primary anastomosis (EPA) for radiation-associated bulbomembranous stenoses using a multi-institutional analysis. The treatment of radiation-associated urethral stenosis is typically complex owing to the adverse impact of radiation on adjacent tissue. METHODS An IRB-approved multi-institutional retrospective review was performed on patients who underwent EPA for bulbomembranous urethral stenosis following prostate radiotherapy. Preoperative patient demographics, operative technique, and postoperative outcomes were abstracted from 1/2007-6/2018. Success was defined as voiding per urethra without the need for endoscopic treatment and a minimum follow-up of 12 months. RESULTS One hundred and thirty-seven patients from 10 centers met study criteria with a mean age of 69.3 years (50-86), stenosis length of 2.3 cm (1-5) and an 86.9% (119/137) success rate at a mean follow-up 32.3 months (12-118). Univariate Cox regression analysis identified increasing patient age (P = .02), stricture length (P <.0001) and combined modality radiotherapy (P = .004) as factors associated with stricture recurrence while body mass index (P = .79), diabetes (P = .93), smoking (P = .62), failed endoscopic treatment (P = .08) and gracilis muscle use (P = .25) were not. On multivariate analysis, increasing patient age (H.R.1.09, 95%CI 1.01-1.16; P = .02) and stenosis length (H.R.2.62, 95%CI 1.49-4.60; P = .001) remained associated with recurrence. Subsequent artificial urinary sphincter was performed in 30 men (21.9%), of which 25 required a transcorporal cuff and 5 developed cuff erosion. CONCLUSIONS EPA for radiation-associated urethral stenosis effectively provides unobstructed instrumentation-free voiding. However, increasing stenosis length and age are independently associated with surgical failure. Patients should be counseled that further surgery for incontinence may be necessary.

Abstract
OBJECTIVE To determine surgical site infection and urinary tract infection (UTI) rates in the setting of urethroplasty. Given significant variation in the utilization of antibiotics, there is an opportunity to improve antibiotic stewardship. This study aims to elucidate the rate of both UTI and surgical site infection after urethroplasty on a standardized perioperative antibiotic regimen, and to obtain patient and operative characteristics that may predict infection. METHODS We prospectively treated 390 patients undergoing urethroplasty at 11 centers with a standardized perioperative antibiotic protocol. Patients had a urine culture or urine analysis within 3 weeks of surgery. After surgery, patients were discharged with an indwelling catheter, removed per usual surgeon practice. All were given nitrofurantoin from discharge until catheter removal. Logistic regression analyses were performed to determine the correlation between patient characteristics or operative categories with post-operative infection. RESULTS The rates of postoperative UTI and wound infection within 30 days were 6.7% and 4.1%, respectively. On multivariate analysis of demographics, comorbidities, and stricture characteristics and repair, only preoperative UTI (P = .012), history of cardiovascular disease (P = .015), and performing a membranous urethroplasty (0.018) were significant predictors of a UTI within 30 days postoperatively. Location of repair nor graft use increased the risk of UTI. There were no factors predictive of postoperative wound infection. CONCLUSION A standardized antibiotic protocol was created to narrow and limit excess antibiotic use. This protocol, with clear definitions of UTI and wound infection, allowed determination of accurate infection rates in urethroplasties. Preoperative UTI, even when properly treated, increases the risk of postoperative UTI.

Abstract
OBJECTIVE To find clinical or radiographic factors that are associated with angioembolization failure after high-grade renal trauma. MATERIAL AND METHODS Patients were selected from the Multi-institutional Genito-Urinary Trauma Study. Included were patients who initially received renal angioembolization after high-grade renal trauma (AAST grades III-V). This cohort was dichotomized into successful or failed angioembolization. Angioembolization was considered a failure if angioembolization was followed by repeat angiography and/or an exploratory laparotomy. RESULTS A total of 67 patients underwent management initially with angioembolization, with failure in 18 (27%) patients. Those with failed angioembolization had a larger proportion ofgrade IV (72% vs 53%) and grade V (22% vs 12%) renal injuries. A total of 53 patients underwent renal angioembolization and had initial radiographic data for review, with failure in 13 cases. The failed renal angioembolization group had larger perirenal hematoma sizes on the initial trauma scan. CONCLUSION Angioembolization after high-grade renal trauma failed in 27% of patients. Failed angioembolization was associated with higher injury grade and a larger perirenal hematoma. Likely these characteristics are associated with high-grade renal trauma that may be less amenable to successful treatment after a single renal angioembolization.

Abstract
PURPOSE Conventional classification of patients with lower urinary tract symptoms into diagnostic categories based on a predefined symptom complex or predominant symptom appears inadequate. This is due to the frequent presentation of patients with multiple urinary symptoms which could not be perfectly categorized into traditional diagnostic groups. We used a novel clustering method to identify subtypes of male patients with lower urinary tract symptoms based on detailed multisymptom information. MATERIALS AND METHODS We analyzed baseline data on 503 care seeking men in the LURN (Symptoms of Lower Urinary Tract Dysfunction Research Network) Observational Cohort Study. Symptoms and symptom severity were assessed using the LUTS (Lower Urinary Tract Symptoms) Tool and the AUA SI (American Urological Association Symptom Index), which include a total of 52 questions. We used a resampling based consensus clustering algorithm to identify patient subtypes with distinct symptom signatures. RESULTS Four distinct symptom clusters were identified. The 166 patients in cluster M1 had predominant symptoms of frequency, nocturia, hesitancy, straining, weak stream, intermittency and incomplete bladder emptying suggestive of bladder outlet obstruction. The 93 patients in cluster M2 mainly endorsed post-micturition symptoms (eg post-void dribbling and post-void leakage) with some weak stream. The 114 patients in cluster M3 reported mostly urinary frequency without incontinence. The 130 patients in cluster M4 reported severe frequency, urgency and urgency incontinence. Most other urinary symptoms statistically differed between cluster pairs. Patient reported outcomes of bowel symptoms, mental health, sleep dysfunction, erectile function and urological pain significantly differed across the clusters. CONCLUSIONS We identified 4 data derived clusters among men seeking care for lower urinary tract symptoms. The clusters differed from traditional diagnostic categories. Further subtype refinement will be done to incorporate clinical data and nonurinary patient reported outcomes.

Abstract
OBJECTIVE To identify factors associated with nonmuscle invasive bladder cancer (NMIBC) American Urological Association (AUA) guideline compliance in a rural state, to evaluate compliance rates over time, and to assess the impact of patient and provider rurality on delivery of NMIBC care. METHODS We identified 847 Iowans in Surveillance, Epidemiology, and End Results-Medicare from 1992 to 2009 with high-grade NMIBC who survived 2 years and were not treated with cystectomy or radiation during this period. Compliance with AUA guidelines was assessed over time and compared to patient demographic, tumor, and treatment institution variables. Impact of rurality was analyzed using Surveillance, Epidemiology, and End Results ZIP code data travel distance of patient to nearest urologist practice location. RESULTS Overall compliance with AUA guidelines was low (<1%), and did not markedly improve over the study period. In the multivariable model, only care at an academic medical center (OR 11.68, 95% CI 7.07-19.29) and tumor stage (Tis; OR 3.24, 95% CI 1.86-5.63) increased the odds of compliance. Patients living closer (<10 miles) to their urologists underwent more cystoscopies than patients living further (>30 miles) but distance did not affect compliance with other measures. Compliance was not associated with cancer-specific survival. CONCLUSION Compliance with post-Transurethral Resection of Bladder Tumor (TURBT) NMIBC treatment guidelines has improved but remains suboptimal in our rural state, and is highly associated with treatment at an academic cancer center for reasons that could not be fully explained with these data.

Abstract
OBJECTIVE To describe the distribution of post-void residual (PVR) volumes across patients with and without lower urinary tract symptoms (LUTS) and examine relationships between self-reported voiding symptoms, storage symptoms, and PVR. METHODS PVR and demographic data were obtained from the Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN) observational cohort study. Self-reported symptoms were collected using the American Urological Association Symptom Index and the LUTS Tool. PVR values were obtained from 2 other cohorts: living kidney donors with unknown LUTS from the Renal and Lung Living Donors Evaluation Study (RELIVE), and continent women in the Establishing the Prevalence of Incontinence (EPI) study, a population-based study of racial differences in urinary incontinence prevalence. RESULTS Across the 3 studies, median PVRs were similar: 26 mL in LURN (n = 880, range 0-932 mL), 20 mL in EPI (n = 166, range 0-400 mL), and 14 mL in RELIVE (n = 191, range 0-352 mL). In LURN, males had 3.6 times higher odds of having PVR > 200 mL (95% CI = 1.72-7.48). In RELIVE, median PVR was significantly higher for males (20 mL vs 0 mL, P= .004). Among women, only the intermittency severity rating was associated with a probability of an elevated PVR. Among men, incomplete emptying and burning severity rating were associated with a higher odds of elevated PVR, but urgency severity ratings were associated with lower odds of elevated PVR. CONCLUSION Care-seeking patients have PVRs similar to those in people with unknown history of LUTS (RELIVE) and without self-reported LUTS (EPI). Although PVR was correlated with voiding symptoms, the mean differences only explain ∼2% of the variance.

Abstract
BACKGROUND Indications for intervention after high-grade renal trauma (HGRT) remain poorly defined. Certain radiographic findings can be used to guide the management of HGRT. We aimed to assess the associations between initial radiographic findings and interventions for hemorrhage after HGRT and to determine hematoma and laceration sizes predicting interventions. METHODS The Genitourinary Trauma Study is a multicenter study including HGRT patients from 14 Level I trauma centers from 2014 to 2017. Admission computed tomography scans were categorized based on multiple variables, including vascular contrast extravasation (VCE), hematoma rim distance (HRD), and size of the deepest laceration. Renal bleeding interventions included angioembolization, surgical packing, renorrhaphy, partial nephrectomy, and nephrectomy. Mixed-effect Poisson regression was used to assess the associations. Receiver operating characteristic analysis was used to define optimal cutoffs for HRD and laceration size. RESULTS In the 326 patients, injury mechanism was blunt in 81%. Forty-seven (14%) patients underwent 51 bleeding interventions, including 19 renal angioembolizations, 16 nephrectomies, and 16 other procedures. In univariable analysis, presence of VCE was associated with a 5.9-fold increase in risk of interventions, and each centimeter increase in HRD was associated with 30% increase in risk of bleeding interventions. An HRD of 3.5 cm or greater and renal laceration depth of 2.5 cm or greater were most predictive of interventions. In multivariable models, VCE and HRD were significantly associated with bleeding interventions. CONCLUSION Our findings support the importance of certain radiographic findings in prediction of bleeding interventions after HGRT. These factors can be used as adjuncts to renal injury grading to guide clinical decision making.

Abstract
PURPOSE To analyze outcomes of posterior urethroplasty following pelvic fracture urethral injuries (PFUI) and to determine risk factors for surgical complexity and success. METHODS Patients who underwent posterior urethroplasty following PFUI were identified in the Trauma and Urologic Reconstructive Network of Surgeons (TURNS) database. Demographics, injury patterns, management strategies, and prior interventions were evaluated. Risk factors for surgical failure and the impact of ancillary urethral lengthening maneuvers (corporal splitting, pubectomy and supracrural rerouting) were evaluated. RESULTS Of the 436 posterior urethroplasties identified, 122 were following PFUI. 83 (68%) patients were acutely managed with suprapubic tubes, while 39 (32%) underwent early endoscopic realignment. 16 (13%) patients underwent pelvic artery embolization in the acute setting. 116 cases (95%) were completed via a perineal approach, while 6 (5%) were performed via an abdominoperineal approach. The need for one or more ancillary maneuvers to gain urethral length occurred in 4 (36%) patients. Of these, 44 (36%) received corporal splitting, 16 (13%) partial or complete pubectomy, and 2 (2%) supracrural rerouting. Younger patients, those with longer distraction defects, and those with a history of angioembolization were more likely to require ancillary maneuvers. 111 patients (91%) did not require repeat intervention during follow-up. Angioembolization (p = 0.03) and longer distraction defects (p = 0.01) were associated with failure. CONCLUSIONS Posterior urethroplasty provides excellent success rates for patients following PFUI. Pelvic angioembolization and increased defect length are associated with increased surgical complexity and risk of failure. Surgeons should be prepared to implement ancillary maneuvers when indicated to achieve a tension-free anastomosis.

Abstract
Altered Toll-like receptor (TLR)4 activation has been identified in several chronic pain conditions but has not been well studied in interstitial cystitis/bladder pain syndrome (IC/BPS). Our previously published human studies indicated that patients with IC/BPS present altered systemic TLR4-mediated inflammatory responses, which were significantly correlated with reported pain severity. In the present study, we sought to determine whether altered TLR4 activation plays a role in pelvic/bladder pain seen in patients with IC/BPS using our validated IC/BPS-like transgenic autoimmune cystitis model (URO-OVA). URO-OVA mice developed responses consistent with pelvic and bladder pain after cystitis induction, which was associated with increased splenocyte production of TLR4-mediated proinflammatory cytokines IL-1β, IL-6, and TNF-α. Increased spinal expression of mRNAs for proinflammatory cytokines IL-6 and TNF-α, glial activation markers CD11b and glial fibrillary acidic protein, and endogenous TLR4 ligand high mobility group box 1 was also observed after cystitis induction. Compared with URO-OVA mice, TLR4-deficient URO-OVA mice developed significantly reduced nociceptive responses, although similar bladder inflammation and voiding dysfunction, after cystitis induction. Intravenous administration of TAK-242 (a TLR4-selective antagonist) significantly attenuated nociceptive responses in cystitis-induced URO-OVA mice, which was associated with reduced splenocyte production of TLR4-mediated IL-1β, IL-6, and TNF-α as well as reduced spinal expression of mRNAs for IL-6, TNF-α, CD11b, glial fibrillary acidic protein, and high mobility group box 1. Our results indicate that altered TLR4 activation plays a critical role in bladder nociception independent of inflammation and voiding dysfunction in the URO-OVA model, providing a potential mechanistic insight and therapeutic target for IC/BPS pain.

Abstract
PURPOSE The purpose of this multi-institutional study was to compare outcomes of transecting and nontransecting anastomotic bulbar urethroplasty. MATERIALS AND METHODS We performed a retrospective, multi-institutional review of the records of 352 patients who underwent transecting or nontransecting anastomotic bulbar urethroplasty performed by 1 of 4 reconstructive urologists from September 2003 to March 2017. Study outcomes were urethroplasty success, defined as urethral patency greater than 16Fr on cystoscopy; de novo sexual dysfunction assessed at 6 months, defined as a 5-point or greater change in the SHIM (Sexual Health Inventory for Men) or a patient reported adverse change; and 90-day complications, defined as Clavien 2 or greater. When appropriate, comparisons were made between the transecting and nontransecting cohorts using the Mantel-Cox test, the t-test or the chi-square test. RESULTS Of the 352 patients with a mean stricture length of 1.7 cm (range 0.5 to 5) 258 and 94 underwent transecting and nontransecting anastomotic bulbar urethroplasty, respectively. The overall success rate was 94.9% at a mean followup of 64.2 months (range 6 to 170). Of the patients 7.1% experienced a 90-day complication and 11.6% reported sexual dysfunction. When comparing transecting and nontransecting techniques, there was no difference in success (93.8% vs 97.9%, Mantel-Cox test p = 0.18) or postoperative complications (8.1% vs 4.3%, p = 0.25). Patients treated with transecting anastomotic urethroplasty were more likely to report an adverse change in sexual function (14.3% vs 4.3%, p = 0.008). On multivariate analysis only transecting urethroplasty was associated with sexual dysfunction (p = 0.01) while age (p = 0.29), stricture length (p = 0.42), etiology (p = 0.99) and surgeon (p = 0.88) were not. CONCLUSIONS Anastomotic urethroplasty is a highly effective surgery with relatively minimal associated morbidity. Nontransecting anastomotic urethroplasty compares quite favorably to the transecting technique and likely reduces the risk of associated sexual dysfunction.
