Mayo Clinic Validation of the AUA Risk Groups for Localized Renal Cell Carcinoma.

PURPOSE: The AUA guidelines introduced a new risk group stratification system based primarily on tumor stage and grade to guide surveillance for patients treated surgically for localized renal cell carcinoma (RCC). We sought to evaluate the predictive ability of these risk groups using progression-free survival (PFS) and cancer-specific survival (CSS), and to compare their performance to that of our published institutional risk models. MATERIALS AND METHODS: We queried our Nephrectomy Registry to identify adults treated with radical or partial nephrectomy for unilateral, M0, clear cell RCC, or papillary RCC from 1980 to 2012. The AUA stratification does not apply to other RCC subtypes as tumor grading for other RCC, such as chromophobe, is not routinely performed. PFS and CSS were estimated using the Kaplan-Meier method. Predictive abilities were evaluated using C indexes from Cox proportional hazards regression models. RESULTS: A total of 3191 patients with clear cell RCC and 633 patients with papillary RCC were included. For patients with clear cell RCC, C indexes for the AUA risk groups and our model were 0.780 and 0.815, respectively (P < .001) for PFS, and 0.811 and 0.857, respectively (P < .001), for CSS. For patients with papillary RCC, C indexes for the AUA risk groups and our model were 0.775 and 0.751, respectively (P = .002) for PFS, and 0.830 and 0.803, respectively (P = .2) for CSS. CONCLUSIONS: The AUA stratification is a parsimonious system for categorizing RCC that provides C indexes of about 0.80 for PFS and CSS following surgery for localized clear cell and papillary RCC.

Development and Validation of a Multivariable Nomogram Predictive of Post-Nephroureterectomy Renal Function.

BACKGROUND AND OBJECTIVE: The timing of perioperative nephrotoxic chemotherapy for upper tract urothelial carcinoma (UTUC) remains controversial and strongly depends on predicted platinum eligibility after radical nephroureterectomy (RNU). The study objective was to develop and validate a multivariable nomogram to predict estimated glomerular filtration rate (eGFR) following RNU. METHODS: This was a multi-institutional retrospective study of patients with UTUC treated with RNU from 2000 to 2020 at seven high-volume referral centers. Use of adjuvant chemotherapy was risk-stratified. Patients were retrospectively randomly allocated 2:1 to discovery and validation cohorts. Discovery data were used to identify independent factors associated with GFR at 1-3 mo after RNU on linear regression, and backward selection was applied for model construction. Accuracy was defined as the percentage of predicted eGFR results within 30% of the corresponding observed eGFR. KEY FINDINGS AND LIMITATIONS: We included 1100 patients, of whom 733 were in the discovery and 367 were in the validation cohort. Multivariable predictors of postoperative eGFR decline included advanced age (odds ratio [OR] -0.18, 95% confidence interval [CI] -0.28 to -0.08), diabetes (OR -2.38, 95% CI -4.64 to -0.11), and hypertension (OR -2.24, 95% CI -4.16 to -0.32). Factors associated with favorable postoperative eGFR included larger tumor size (OR 10.57, 95% CI 7.4-13.74 for tumors >5 cm vs ≤2 cm) and preoperative eGFR (OR 0.44, 95% CI 0.39-0.49). A composite nomogram predicted postoperative eGFR with good accuracy in both the discovery (80.5%) and validation (78.6%) cohorts. Limitations include exclusion of patients who received neoadjuvant chemotherapy. CONCLUSIONS: A nomogram that incorporates ubiquitous preoperative clinical variables can predict post-RNU eGFR and was validated with an independent cohort. PATIENT SUMMARY: We developed a tool that uses patient data to predict eligibility for chemotherapy after surgery to remove the kidney and ureter in patients with cancer in the upper urinary tract.

Diagnosis, workup, and risk stratification of upper tract urothelial carcinoma.

Upper tract urothelial carcinoma (UTUC) is a relatively rare disease that presents unique challenges to urologists from both a diagnostic and management standpoint. UTUC is a clinically heterogenous disease with a varied natural history, and given its location in the upper urinary tract, treatment has the potential to cause or worsen chronic kidney disease. Therefore, physicians caring for patients with UTUC must be facile with multiple diagnostic and therapeutic strategies in order to provide optimal patient care. We present an overview of the epidemiology, histology, risk factors, and contemporary approach to the diagnosis, laboratory evaluation, imaging, and risk stratification for patients with UTUC. Computerized tomographic urography, thorough endoscopic evaluation, and biopsy (endoscopically or percutaneously) remain the standard of care for the diagnosis and staging of patients with suspected UTUC. Preoperative nomograms are vital to select patients more optimally for preoperative systemic chemotherapy and facilitate clinical trial enrollment. A thorough understanding of the various diagnostic challenges, imaging/pathologic limitations, biomarkers, and risk stratification tools will allow us as a field to develop new modalities to improve our diagnostic capabilities and reduce the risk of under diagnosis and over treatment for our patients.

Impact of Inner Layer Renorrhaphy Suture on Renal Artery Pseudoaneurysm Formation Following Robotic-assisted Partial Nephrectomy.

OBJECTIVE: To report the impact of resection base inner layer renorrhaphy suture type on renal artery pseudoaneurysm (RAP) rate following robotic-assisted partial nephrectomy (RAPN). METHODS: Five hundred and sixty-three consecutive RAPNs performed by a single surgeon were retrospectively reviewed. Patients were classified into 3 categories: (1) No base suture, (2) monofilament barbed suture (2-0 V-Loc 180 absorbable suture, Medtronic, Minneapolis, MN), (3) polyglactin 910 (2-0 Vicryl coated suture, Ethicon Inc, Cincinnati, OH). In a secondary analysis, we evaluated suturing (Vicryl and V-Loc) vs no base suture. All patients had outer cortical renorrhaphy performed with 0-Vicryl suture utilizing the standard sliding clip technique. RESULTS: One hundred ten patients (19.5%) had V-Loc suturing, 255 patients (45.3%) had Vicryl suturing, and 198 patients (35.2%) had no base suture. Patients had a median age of 62.8years (interquartile range: 53.5-69.7) and median RENAL score was 8 (6-9). Median mass size from preoperative imaging was 3.0 cm (2.5-4.0) for V-Loc, 3.3 cm (2.5-4.2) for Vicryl, and 2.0 cm (1.8-3.0) for no base suture (P < .001). Overall, 21 patients (3.7%) developed a symptomatic postoperative RAP. The rate of RAP was 3.6% (4/110) for V-Loc, 3.9% (10/255) for 2-0 Vicryl, and 3.5% (7/198) for no base suture (P = 1.00). Similarly, the rate of RAP was 3.5% (7/198) for no base suture and 3.8% (14/365) for base suture (P = 1.00). CONCLUSION: Utilization of base suture and type of base suture used during RAPN was not predictive of postoperative RAP development.

Oncological outcomes of visibly complete transurethral resection prior to neoadjuvant chemotherapy for bladder cancer

ABSTRACT Purpose: To evaluate the potential oncologic benefit of a visibly complete transurethral resection of a bladder tumor (TURBT) prior to neoadjuvant chemotherapy (NAC) and radical cystectomy (RC). Materials and Methods: We identified patients who received NAC and RC between 2011-2021. Records were reviewed to assess TURBT completeness. The primary outcome was pathologic downstaging (<ypT2N0), with complete pathologic response (ypT0N0) and survival as secondary endpoints. Logistic regression and Cox proportional hazards models were utilized. Results: We identified 153 patients, including 116 (76%) with a complete TURBT. Sixty-four (42%) achieved <ypT2N0 and 43 (28%) achieved ypT0N0. When comparing those with and without a complete TURBT, there was no significant difference in the proportion with <ypT2N0 (43% vs 38%, P=0.57) or ypT0N0 (28% vs 27%, P=0.87). After median follow-up of 3.6 years (IQR 1.5-5.1), 86 patients died, 37 died from bladder cancer, and 61 had recurrence. We did not observe a statistically significant association of complete TURBT with cancer-specific or recurrence-free survival (p≥0.20), although the hazard of death from any cause was significantly higher among those with incomplete TURBT even after adjusting for ECOG and pathologic T stage, HR 1.77 (95% CI 1.04-3.00, P=.034). Conclusions: A visibly complete TURBT was not associated with pathologic downstaging, cancer-specific or recurrence-free survival following NAC and RC. These data do not support the need for repeat TURBT to achieve a visibly complete resection if NAC and RC are planned.

Circulating antigen-primed cytotoxic T-cells in patients with renal tumors treated with surgery.

INTRODUCTION: Systemic immunotherapy has changed the paradigm of treatment of advanced renal cell carcinoma, but nephrectomy continues to benefit selected patients. While we continue to identify mechanisms behind drug resistance, the effect of surgery on natural anti-tumor immunity is poorly understood. Specifically, peripheral blood mononuclear cell (PBMC) profile and tumor reactive cytotoxic T lymphocytes changes secondary to tumor resection have not been extensively characterized. Hence, we aimed to evaluate the effect of nephrectomy on PMBC profile and circulating antigen-primed CD8+ T-cells for patients undergoing solid renal mass resection. METHODS: Patients with localized or metastatic solid renal masses who underwent nephrectomy from 2016 to 2018 were enrolled. Blood samples were collected at 3 timepoints for PBMCs analysis (pre-op, 1 day, and 3 months post-op). Flow cytometry was used to identify CD11ahigh CD8+ T lymphocytes that were then further characterized according to the expression of CX3CR1/GZMB, Ki67, Bim, and PD-1. Changes in circulating CD8+ T-cells from pre-op to 1 day and 3 months post-op were evaluated using Wilcoxon signed rank tests. RESULTS: Antigen-primed CX3CR1+GZMB+ T-cells significantly increased by 3 months after surgery among patients with RCC (0.8 × 109 cells; P = 0.01). In contrast, there was a decrease in absolute numbers of Bim+ T-cells at 3 months (-1.9 × 109 cells; P = 0.02). There were no significant absolute changes in PD-1+ (-1.4 × 109; P = 0.7) and CD11ahigh CD8+ T lymphocytes (1.3 × 109; P = 0.9). Ki67+ T-cells decreased by 3 months (-0.8 × 109; P < 0.001). CONCLUSIONS: Nephrectomy is associated with an increase in cytolytic antigen-primed CD8+ T-cells and specific PBMC profile changes. Further studies are warranted to ascertain the role surgery may have in the restoration of anti-tumor immunity.

Features associated with travel distance for radical cystectomy in Florida: Implications for access to care.

INTRODUCTION: Characteristics associated with travel distance for radical cystectomy (RC) remain incompletely defined but are needed to inform efforts to bridge gaps in care. Therefore, we assessed features associated with travel distance for RC in a statewide dataset. METHODS: We identified RC patients in the Florida Inpatient Discharge dataset from 2013 to 2019. Travel distance was estimated using zip code centroids. The primary outcome was travel >50 miles for RC. Secondary outcomes included inpatient mortality, nonhome discharge, and inpatient complications. U.S. County Health Rankings were included as model covariates. Mixed effects logistic regression models accounting for clustering within hospitals were utilized. RESULTS: We identified 4,209 patients, of whom 2,284 (54%) traveled <25 miles, 654 (16%) traveled 25 to 50 miles, and 1271 (30%) traveled >50 miles. Patients who traveled >50 miles primarily lived in central and southwest Florida. Following multivariable adjustment, patients traveling >50 miles were less likely to be Hispanic/Latino (odds ratio [OR] 0.35, 95% CI: 0.23-0.51), and more likely to reside in a county with the lowest health behavior (OR 6.48, 95% CI: 3.81-11.2) and lowest socioeconomic (OR 7.63, 95% CI: 5.30-11.1) rankings compared to those traveling <25 miles (all P < 0.01). Travel distance >50 miles was associated with treatment at a high-volume center and significantly lower risks of inpatient mortality, nonhome discharge, and postoperative complications (all P < 0.02). CONCLUSION: These data identify characteristics of patients and communities in the state of Florida with potentially impaired access to RC care and can be used to guide outreach efforts designed to improve access to care.

Oncological outcomes of visibly complete transurethral resection prior to neoadjuvant chemotherapy for bladder cancer.

PURPOSE: To evaluate the potential oncologic benefit of a visibly complete transurethral resection of a bladder tumor (TURBT) prior to neoadjuvant chemotherapy (NAC) and radical cystectomy (RC). MATERIALS AND METHODS: We identified patients who received NAC and RC between 2011-2021. Records were reviewed to assess TURBT completeness. The primary outcome was pathologic downstaging (

Efficacy of RestoreX after prostatectomy: open-label phase of a randomized controlled trial.

OBJECTIVE: To report open-label phase data from a recent randomized controlled trial (RCT), after previous data from that study showed improved penile length and erectile function among post-prostatectomy men treated with Restorex penile traction therapy (RxPTT). MATERIALS AND METHODS: An RCT (NCT05244486) was performed to evaluate RxPTT vs no treatment (Tx) for 5 months, which was followed by a 3-month open-label phase. Men were stratified based on as-treated data: Group 1 = No Tx; Group 2 = No Tx → Tx; Group 3 = Tx → No Tx; Group 4 = Tx. Assessments included stretched penile length and standardized (International Index of Erectile Function [IIEF]) and non-standardized questionnaires. RESULTS: A total of 82 men were enrolled (mean age 58.6 years) with 9-month data available in 45 of the men. Baseline characteristics were similar among the cohorts. Comparing Group 1 and Group 4 (respectively), notable differences included: IIEF Erectile Function domain (IIEF-EF) score (-8 vs -0.5; P = 0.16), penile length (-0.1 vs +1.7 cm; P < 0.01), intracavernosal injection use (86% vs 14%; P < 0.01), Sexual Encounter Profile (SEP) Question 2 (50% vs 100%; P < 0.01), SEP Question 3 (33% vs 100%; P < 0.01). Men who crossed over to Tx (Group 2) failed to achieve equivalent improvements in length (+0.5 cm) or sexual function (IIEF-EF score -6) compared to men treated early (Groups 3 and 4). Those who crossed over to no treatment after initial treatment (Group 3) experienced preserved length (+1.8 cm), and erectile function (IIEF-EF score +0) despite therapy discontinuation. CONCLUSIONS: Use of RxPTT beginning 1 month post-prostatectomy results in improved penile length and erectile function, with benefits maintained after discontinuing therapy. If confirmed, these results represent the first postoperative therapy shown in a RCT to improve erectile function post-prostatectomy. External validation is warranted.

Disparities in access to high-volume centers and in hospital discharge status following radical cystectomy in Florida.

INTRODUCTION: Centralization of radical cystectomy (RC) improves outcomes but may unintentionally exacerbate existing disparities in care. Our objective was to assess disparities in access to high-volume RC centers and in postoperative recovery. METHODS: We identified RC patients in the Florida Inpatient Data File from 2013 to 2019. Hospital annual cystectomy volume was categorized as low, medium, or high using data-derived 75th and 90th quantiles: <5, 5 to 13, and >13 RC/year. Outcomes included inpatient mortality, non-home discharge, in-hospital complications, length of stay (LOS) and surgery in a low-volume hospital. Mixed-effects regression models accounting for clustering within centers were utilized. RESULTS: Among 4,396 patients treated at 105 centers, RC at a high-volume center was associated with lower odds of mortality, non-home discharge, shorter length of stay and fewer complications (all P ≤ 0.001). Characteristics associated with receiving care in a low-volume hospital included Black race (OR 1.67, 95% CI 1.14-2.39), Hispanic/Latino ethnicity (OR 1.74, 95% CI 1.32-2.00), and residing in northeast (OR 2.11, 95% CI 1.58-2.80) or west Florida (OR 1.34, 95% CI 1.05-1.71). Black patients had increased odds of non-home discharge (OR 1.91, 95% CI 1.27-2.86) and longer LOS (IRR 1.17, 95% CI 1.08-1.27), but no difference in the rate or number of postoperative complications (P > 0.2). CONCLUSION: In Florida, we observed racial and geographic disparities in likelihood of undergoing RC at a high-volume hospital, and that Black patients experienced longer LOS and lower odds of home discharge despite similar rates of complications. Efforts to increase access to high-value RC care for these vulnerable populations are needed.

Rotator cuff repair in upper extremity ambulators: an assessment of longitudinal outcomes.

Background: Individuals who rely on wheelchairs, walkers, and crutches for ambulation have an increased incidence of rotator cuff tears due to altered shoulder biomechanics and increased force transmission across the shoulder joint. The purpose of our study is to review our longitudinal outcomes treating upper extremity ambulators to guide patient expectations and identify risk factors for rotator cuff repair failure. Methods: A total of fifteen patients were included after a cohort of thirty-nine patients were identified. The mean age was 54.9 years at the time of index rotator cuff repair, with each patient requiring either wheelchair, cane, walker, or crutches for ambulation. Clinical outcomes were measured (strength, range of motion, and pain scores), and patient-reported outcome scores (American Shoulder and Elbow Surgeons, Simple Shoulder Test, and University of California Los Angeles functional shoulder assessment tool) were obtained. No follow-up imaging was obtained unless indicated by a change in clinical status. Results: Within our cohort, 14 of 15 (93%) presented with supraspinatus tears, 7 of 15 (47%) with infraspinatus tears, and only 3 of 15 (20%) with subscapularis pathology. Additionally, the rates of concurrent biceps pathology or acromioclavicular joint pathology were significant at 53% and 73%, respectively. Only one patient in our cohort experienced known failure of cuff repair, despite longitudinal follow-up at an average of 97 months following surgery, however, routine follow-up imaging was not obtained. There were statistically significant improvements in visual analog scale pain scores, forward flexion ROM and strength, and abduction ROM. Additionally, statistically significant improvements were noted in all patient-reported outcome scores measured. Conclusion: Despite the apparent risks associated in rotator cuff repair in upper extremity ambulators, these patients demonstrate clinically significant improvements following surgery. Appreciating additional pathology beyond the rotator cuff is important in formulating a treatment plan.

Renin Production by Juxtaglomerular Cell Tumors and Clear Cell Renal Cell Carcinoma and the Role of Angiotensin Signaling Inhibitors.

OBJECTIVE: To profile juxtaglomerular cell tumors (JXG) and histologic mimics by analyzing renin expression; to identify non-JXG renin-producing tumors in The Cancer Genome Atlas (TCGA) data sets; and to define the prevalence of hypertension (HTN) and patient outcomes with angiotensin signaling inhibitor (ASI) use in tumors of interest. PATIENTS AND METHODS: Thirteen JXGs and 10 glomus tumors (GTs), a histologic mimic, were evaluated for clinicopathologic features; TCGA data were analyzed to identify non-JXG renin-overexpressing tumors. An institutional registry was queried to determine the incidence of HTN, the use of ASIs in hypertensive patients, and the impact of ASIs on outcomes including progression-free survival (PFS) in a tumor type with high renin expression (clear cell renal cell carcinoma [CC-RCC] diagnosed between January 1, 2005, and December 31, 2012). RESULTS: We found an association between renin production and HTN in JXG compared with GT. Analysis of TCGA data found that a subset of CC-RCCs overexpress renin relative to 29 other tumor types. Furthermore, analysis of our institutional registry revealed a high prevalence (64%) of HTN among 1203 patients treated with radical or partial nephrectomy for nonmetastatic CC-RCC. On multivariable Cox regression, patients with HTN treated with ASIs (34%) had improved PFS (hazard ratio, 0.76; 95% CI, 0.57 to 1.00; P=.05) compared with patients with HTN not treated with ASIs (30%). CONCLUSION: The identification of renin expression in a subset of CC-RCC may provide a biologic rationale for the high prevalence of HTN and improved PFS with ASI use in hypertensive patients with nonmetastatic CC-RCC.

Intensive preoperative ostomy education for the radical cystectomy patient.

OBJECTIVES: Patients undergoing radical cystectomy with ileal conduit formation usually receive training on the use of their stoma during their initial hospitalization - while actively recovering from surgery - often with little follow-up or reinforcement. Many of these patients are not equipped to deal with these significant body changes, which can lead to additional clinic visits, stoma-related complications, and decreased patient satisfaction/health-related quality of life (HRQOL). In an effort to improve patient education, we sought to evaluate the feasibility of implementing a preoperative comprehensive stoma education session termed the "stoma bootcamp" for patients scheduled for a radical cystectomy and ileal conduit (RCIC). We tracked patient related outcomes to determine its impact. METHODS: We performed a longitudinal, quality-improvement feasibility study at the University of Kansas Health System. All patients who were scheduled to undergo a RCIC for bladder cancer were offered enrollment into the study at their preoperative clinic visit. The "stoma boot camp" consisted of a 3-hour group session within 2 weeks of the surgery date. Patients were given a short presentation by residents and advanced practice providers regarding the operation, recovery, and expectations for their post-operative care. Ostomy nurses then demonstrated basic urostomy care - pouching, sizing, emptying - along with trouble-shooting tips for common ostomy problems. Measurements of HRQOL questionnaires were completed at the initial visit, after "boot camp," and at defined time points after surgery for 12 weeks. This included using an ostomy adjustment score. Length of stay, unplanned stoma-related interventions, and re-admissions within 30 days were also tracked. RESULTS: In this initial pilot program, 51 patients participated in the stoma bootcamp. The patients had an average ostomy adjustment score (OAS) of 150.4 (95% CI 142.0, 158.8) at discharge from the hospital, and these high OAS levels persisted throughout the 12 weeks of follow-up data without any significant decline. Short-form 36 (SF-36) scores demonstrated numerical improvements in each individual category at the 6-week mark above baseline. These improvements persisted at the 12-week mark. CONCLUSIONS: In this study we were able to establish the feasibility of implementing a preoperative comprehensive stoma education session for patients scheduled for a RCIC. Additionally, we were able to document favorable HRQOL data and improved ostomy adjustment scores surrounding the education session.

Role of Lymphadenectomy during Radical Cystectomy for Nonmuscle-Invasive Bladder Cancer: Results from a Multi-Institutional Experience.

PURPOSE: While lymph node dissection (LND) at radical cystectomy (RC) for muscle-invasive bladder cancer has been studied extensively, the role of LND for nonmuscle-invasive bladder cancer (NMIBC) remains incompletely defined. Herein, we aim to assess the association between extent of LND during RC for NMIBC and local pelvic recurrence-free survival (LPRS), cancer-specific survival (CSS) and overall survival (OS). MATERIALS AND METHODS: A multi-institutional retrospective review was performed of patients with NMIBC undergoing RC at 3 large tertiary referral centers. To identify a threshold for lymph node yield (LNY) to optimize LPRS, CSS and OS, separate Cox regression models were developed for each possible LNY threshold. Model performance including Q-statistics and hazard ratios (HRs) were used to identify optimal LNY thresholds. RESULTS: A total of 1,647 patients underwent RC for NMIBC, with a median LNY of 15 (quartiles 9,23). Model performance curves suggested LNY of 10 and 20 to optimize LPRS and CSS/OS, respectively. On multivariable regression, LNY >10 was associated with lower risk of LPR compared to LNY ≤10 (HR 0.63, 95% CI 0.42-0.93, p=0.02). Similarly, LNY >20 was associated with improved CSS (HR 0.67, 95% CI 0.52-0.87, p=0.002) and OS (HR 0.75, 95% CI 0.64-0.88, p <0.001) compared to LNY ≤20. Similar results were observed in the cT1 and cTis subgroups. CONCLUSIONS: Greater extent of LND during RC for NMIBC is associated with improved LPRS, CSS and OS, supporting the inclusion of LND during RC for NMIBC, particularly among patients with cTis or cT1 disease. Future prospective studies are warranted to assess the ideal anatomical template of LND in NMIBC.

A Contemporary Analysis of Urethral Recurrence following Radical Cystectomy.

PURPOSE: Oncologic outcomes following urethral recurrence (UR) remain incompletely described, with reports limited by small cohort sizes. We evaluated risk factors for UR as well as cancer-specific survival (CSS) and overall survival (OS) among patients with UR. MATERIALS AND METHODS: We reviewed our institutional radical cystectomy (RC) registry to identify patients with UR. Cox proportional hazards regression was used to assess risk factors for UR. Kaplan-Meier and Cox models were used to assess the relationship between UR and CSS/OS as well as to compare outcomes following symptomatic vs asymptomatic presentation of UR. RESULTS: Overall, 2,930 patients underwent RC from 1980 to 2018, with a median postoperative followup of 7.1 years (IQR 2.8-13.1), of whom 144 (4.9%) were subsequently diagnosed with UR. Carcinoma in situ (HR 1.98, 95% CI 1.30-3.04), multifocal disease (HR 1.59, 95% CI 1.07-2.36) and prostatic urethral involvement at RC (HR 3.01, 95% CI 1.98-4.57) were associated with increased risk of UR. UR was associated with decreased CSS (HR 7.30, 95% CI 5.46-9.76) and OS (HR 1.86, 95% CI 1.54-2.24). A total of 63/144 patients were diagnosed with UR based on symptoms, while 104/144 patients with UR underwent urethrectomy. Patients with symptomatic UR had higher tumor stage at urethrectomy (≥pT2 in 13.1% vs 3.1%, p=0.007), while patients with asymptomatic UR experienced longer median CSS (12.1 vs 6.1 years) and OS (8.30 vs 4.82 years; p=0.05 for both). CONCLUSIONS: We identified pathological risk factors for UR after RC and report adverse subsequent survival outcomes for these patients. Presentation with symptomatic UR was associated with higher tumor stage and poorer prognosis, supporting a value to continued urethral surveillance after RC.

Fertility in Adolescents With Klinefelter Syndrome: A Survey of Current Clinical Practice.

CONTEXT: Progress has been made in determining the fertility timeline and potential in adolescents with Klinefelter syndrome; however, medical professionals are currently without protocols to guide treatment. OBJECTIVE: To evaluate the current practices regarding fertility and andrology care in adolescent males with Klinefelter syndrome. DESIGN: A 24-question survey was developed to elicit practitioner background/expertise and management practices. This was distributed to members of the Society for the Study of Male Reproduction, the Pediatric Endocrine Society, and the Endocrine Society. SETTING: N/A. PATIENTS: Adolescent males with Klinefelter syndrome. INTERVENTION: None. MAIN OUTCOME MEASURED: Current practices regarding fertility and andrology care. RESULTS: 232 responses were received from 133 (57%) adult endocrinologists, 60 (26%) pediatric endocrinologists, and 39 (17%) urologists. Among these, 69% of respondents were in academics, 62% practiced for > 10 years, and 65% received formal training in Klinefelter syndrome. All specialties encouraged sperm banking in late puberty, however most disagreed with the practice in early puberty. Seventy-eight percent agreed that testicular biopsy should be offered if no sperm was found in the ejaculate. The perceived optimal age for testicular biopsy varied among specialists. Clinical symptoms of hypogonadism (28%), rising gonadotropin levels (15%), and testosterone levels (15%) were the most commonly cited reasons for initiation of testosterone replacement therapy. CONCLUSION: Fertility preservation practices in adolescents with Klinefelter syndrome vary greatly within and among the specialties caring for these patients. These findings should guide future research and highlight the importance of establishing clinical practice guidelines.

Development, acceptability, appropriateness and appeal of a cancer clinical trials implementation intervention for rural- and minority-serving urology practices.

BACKGROUND: Few community urologists offer cancer patients the opportunity to participate in cancer clinical trials, despite national guidelines that recommend it, depriving an estimated 260,000 urological cancer patients of guideline-concordant care each year. Existing strategies to increase urologists' offer of clinical trials are designed for resource-rich environments and are not feasible for many community urologists. We sought to design an implementation intervention for dissemination in under-resourced community urology practices and to compare its acceptability, appropriateness and adoption appeal among trial-naïve and trial-experienced urologists. METHODS: We used a design-for-dissemination approach, informed by the Theoretical Domains Framework and Behavior Change Wheel, to match determinants of the clinical trial offer to theoretically informed implementation strategies. We described the implementation intervention in evaluation workshops offered at urology professional society meetings. We surveyed participants to assess the implementation intervention's acceptability and appropriateness using validated instruments. We also measured adoption appeal, intention to adopt and previous trial offer. RESULTS: Our design process resulted in a multi-modal implementation intervention, comprised of multiple implementation strategies designed to address six domains from the Theoretical Domains Framework. Evaluation workshops delivered at four meetings, convened five separate professional societies. Sixty-one percent of those offered an opportunity to participate in the implementation intervention indicated intention to adopt. Average implementation intervention acceptability and appropriateness ratings were 4.4 and 4.4 (out of 5), respectively. Acceptability scores were statistically significantly higher among those offering trials compared to those not (p = 0.03). Appropriateness scores did not differ between those offering trials and those not (p = 0.24). After urologists ranked their top three innovation attributes, 43% of urologists included practice reputation in their top three reasons for offering clinical trials; 30% listed practice differentiation among their top three reasons. No statistically significant differences were found between those who offered trials and those who did not among any of the innovation attributes. CONCLUSIONS: LEARN|INFORM|RECRUIT is a promising implementation intervention to address low accrual to clinical trials, poised for implementation and effectiveness testing. The implementation intervention is appealing to its target audience and may have equal uptake among trial-naïve and trial-experienced practices.
