Peri-operative outcomes following radical prostatectomy in the setting of advanced prostate cancer.

OBJECTIVE: To compare the peri-operative outcomes of radical prostatectomy (RP) for locally advanced, node-positive, and metastatic prostate cancer (PCa), as determined through pathological staging, using the American College of Surgeons National Surgical Quality Improvement Project. METHODS: We identified RP procedures performed between 2019 and 2021. Patients were stratified by pathological staging to compare the effect of locally advanced disease (T3-4), node positivity (N+) and metastasis (M+) vs localised PCa (T1-2 N0 M0). Baseline demographics and 30-day outcomes, including operating time, length of hospital stay (LOS), 30-day mortality, readmissions, reoperations, major complications, minor complications and surgery-specific complications, were compared between groups. RESULTS: Pathological staging data were available for 9276 RPs. Baseline demographics were comparable. There was a slightly higher rate of minor complications in the locally advanced cohort, but no significant difference in major complications, 30-day mortality, readmissions, or rectal injuries. Node positivity was associated with longer operating time, LOS, and some slightly increased rates of 30-day complications. RP in patients with metastatic disease appeared to be similarly safe to RP in patients with M0 disease, although it was associated with a longer LOS and slightly increased rates of certain complications. CONCLUSIONS: For patients with pathologically determined locally advanced, node-positive, and metastatic PCa, RP appears to be safe, and is not associated with significantly higher rates of 30-day mortality or major complications compared to RP for localised PCa. This study adds to the growing body of literature investigating the role of RP for advanced PCa; further studies are needed to better characterise the risks and benefits of surgery in such patients.

Differences in mutations across tumour sizes in clear-cell renal cell carcinoma.

OBJECTIVE: To assess the distribution of key mutations across tumour sizes in clear-cell renal cell carcinoma (ccRCC), and secondarily to examine the prognostic impact of aggressive mutations in smaller ccRCCs. PATIENT AND METHODS: The distribution of mutations (VHL, PBRM1, SETD2, BAP1 and CDKN2A loss) across tumour sizes was assessed in 1039 ccRCCs treated with nephrectomy in cohorts obtained from the Tracking Cancer Evolution (TRACERx), The Cancer Genome Atlas (TCGA) and the Cancer Genomics of the Kidney (CAGEKID) projects. Logistic regression was used to model the presence of each mutation against size. In our secondary analysis, we assessed a subset of ccRCCs ≤7 cm for associations of key aggressive mutations (SETD2, BAP1, and CDKN2A loss) with metastasis, invasive disease and overall survival, while controlling for size. A subset of localised tumours ≤7 cm was also used to assess associations with recurrence after nephrectomy. RESULTS: On logistic regression, each 1-cm increase in tumour size was associated with aggressive mutations, SETD2, BAP1, and CDKN2A loss, at odds ratios (ORs) of 1.09, 1.10 and 1.19 (P < 0.001), whereas no significant association was observed between tumour size and PBRM1 (OR 1.02; P = 0.23). VHL was mildly negatively associated with a 1-cm increase in size (OR 0.95; P = 0.01). Among tumours ≤7 cm, SETD2 and CDKN2A loss were associated with metastatic disease at ORs of 3.86 and 3.84 (P < 0.05) while controlling for tumour size. CDKN2A loss was associated with worse overall survival, with a hazard ratio (HR) of 2.19 (P = 0.03). Among localised tumours ≤7 cm, SETD2 was associated with worse recurrence-free survival (HR 2.00; P = 0.03). CONCLUSION: Large and small ccRCCs are genomically different. Aggressive mutations, namely, SETD2, BAP1, and CDKN2A loss, are rarely observed in small ccRCCs and are observed more frequently in larger tumours. However, when present in tumours ≤7 cm, SETD2 mutations and CDKN2A loss were still independently associated with invasive disease, metastasis, worse survival, and recurrence after resection, after controlling for size.

Feasibility, acceptability, and behavioral outcomes of a multimodal intervention for prostate cancer patients: Experience from the MARTINI lifestyle program.

BACKGROUND: Prostate cancer (PCa) is the most frequently diagnosed malignant tumor in men. The potential benefit of a healthy lifestyle contrasts sharply with the observed poor adherence to current international lifestyle guidelines. Thus, well-designed sustainable interventions of aftercare that can be translated into routine practice are highly recommended. The present pilot study aimed to evaluate the feasibility and acceptability of a multimodal lifestyle intervention program in PCa patients after radical prostatectomy (RP). METHODS: In a single-arm study, carried out at the Martini-Klinik of the University Medical Center Hamburg-Eppendorf, Germany, 59 eligible men with locally advanced PCa were recruited within 3-6 months after RP and assigned to a multimodal lifestyle program. The program consisted of 10 weekly 6-7 h course days, with a focus on dietary control, physical activity (per World Cancer Research Fund recommendations) and psychological support. Primary objectives were feasibility, acceptability, completion rate, and safety. In addition, changes in lifestyle, psychological well-being, clinical and laboratory values were assessed. The study was registered in the German Clinical Trials Register (No. DRK S00015288 [MARTINI-Lifestyle-cohort] [www.germanctr.de]). RESULTS: A high program acceptance was observed. Only three participants (5%) dropped out of the program prematurely. Personal feedback reflected appreciation for participation, personal gain through new knowledge and through the group experience. Without exception, all participants have taken part in follow-up examinations and no adverse events or incidents occurred. In addition, changes in lifestyle habits, clinical parameters and improved quality of life were detected. CONCLUSION: The MARTINI lifestyle program appears feasible and safe, and acceptance of the multimodal intervention was high among PCa patients. These encouraging results favor conducting a large multicenter trial to implement the program into routine practice and to evaluate the effectiveness of the intervention on survival and quality of life.

Impact of an Expanded Definition of Family History on Outcomes of Active Surveillance for Prostate Cancer.

PURPOSE: Despite family history being an established risk factor for prostate cancer, the role of a broader definition of family history inclusive of not just prostate cancer but other genetically related malignancies has not been investigated in the active surveillance population. Here, we evaluate the impact of an expanded definition of family history on active surveillance outcomes. MATERIALS AND METHODS: Patients undergoing active surveillance for prostate cancer at Massachusetts General Hospital from 1997-2019 with detailed data available on family cancer history were identified. Primary outcome was biopsy progression-free survival, and secondary outcomes were treatment-free survival, adverse pathological features at prostatectomy, and biochemical recurrence after treatment. Statistical analyses were conducted using the Kaplan-Meier method and Cox regression. RESULTS: Among 855 evaluable patients, 300 (35.1%) patients had any family history of prostate cancer, and 95 (11.1%) had a family history of related malignancies suggestive of a hereditary cancer syndrome. Family history of prostate cancer alone was not associated with biopsy progression, whereas family history suggestive of a hereditary cancer syndrome was associated with a significantly increased risk of biopsy progression (HR 1.43, 95%CI 1.01-2.02), independent of other known clinicopathological risk factors in multivariable analysis. Similarly, family history suggestive of a hereditary cancer syndrome was associated with significantly lower treatment-free survival (HR 1.58, 95%CI 1.14-2.18) in multivariable analysis. No significant association was found between family history and adverse features on surgical pathology or biochemical recurrence. CONCLUSIONS: An expanded family history suggestive of a hereditary cancer syndrome is an independent predictor of biopsy progression during active surveillance. Men with such a family history may still be offered active surveillance but should be counseled regarding the higher risk of disease progression.

MRI as a screening tool for prostate cancer: current evidence and future challenges.

PURPOSE: Prostate cancer (PCa) screening, which relies on prostate-specific antigen (PSA) testing, is a contentious topic that received negative attention due to the low sensitivity and specificity of PSA to detect clinically significant PCa. In this context, due to the higher sensitivity and specificity of magnetic resonance imaging (MRI), several trials investigate the feasibility of "MRI-only" screening approaches, and question if PSA testing may be replaced within prostate cancer screening programs. METHODS: This narrative review discusses the current literature and the outlook on the potential of MRI-based PCa screening. RESULTS: Several prospective randomized population-based trials are ongoing. Preliminary study results appear to favor the "MRI-only" approach. However, MRI-based PCa screening programs face a variety of obstacles that have yet to be fully addressed. These include the increased cost of MRI, lack of broad availability, differences in MRI acquisition and interpretation protocols, and lack of long-term impact on cancer-specific mortality. Partly, these issues are being addressed by shorter and simpler MRI approaches (5-20 min bi-parametric MRI), novel quality indicators (PI-QUAL) and the implementation of radiomics (deep learning, machine learning). CONCLUSION: Although promising preliminary results were reported, MRI-based PCa screening still lack long-term data on crucial endpoints such as the impact of MRI screening on mortality. Furthermore, the issues of availability, cost-effectiveness, and differences in MRI acquisition and interpretation still need to be addressed.

The evolving role of contrast-enhanced ultrasound in urology: a review.

PURPOSE: Ultrasound's versatility and ease of use has expanded its application in many clinical settings. Technological advancements with contrast-enhanced ultrasound (CEUS) have allowed high quality imaging similar to CT or MRI with lower risk of contrast toxicity and radiation exposure. In this review article we examine the development of CEUS and its vast applications in the field of urology. METHODS: A PubMed literature search was performed using keywords: contrast enhanced ultrasound, prostate cancer, renal cancer, and multiparametric ultrasound. RESULTS: The development of CEUS has improved transrectal ultrasound imaging with increased detection of prostate cancer (PCa). Further enhancements of CEUS such as subharmonic imaging (SHI), flash replenishment imaging (FRI) and contrast ultrasound dispersion imaging (CUDI) allow improved PCa diagnosis. CEUS has also emerged as an important tool in characterizing suspicious renal mass without compromising renal function with contrast imaging. CONCLUSION: CEUS has modernized imaging and diagnosis of prostate and renal cancer. Future advancements and utilization of CEUS will allow its expansion into other urological subspecialties.

Does a prior cancer diagnosis impact PSA testing? Results from the National Health Interview Survey.

INTRODUCTION: Prostate-specific antigen (PSA) testing remains a controversial issue. However, most urological guidelines recommend PSA testing in men aged 55-69 through a shared decision-making process with the patient. The impact of prior cancer diagnosis on PSA testing is not well-known. To compare PSA testing in men aged 55-69 years with and without a history of cancer (excluding prostate cancer patients). MATERIALS AND METHODS: Utilizing the National Health Interview Survey (NHIS), a retrospective cross-sectional study during the year 2018 was carried out. Multivariable logistic regression analysis was implemented to demonstrate potential associations with PSA testing and assess the association of cancer history. RESULTS: A total of 2,892 men aged 55-69 years from the NHIS survey who met the inclusion criteria were analyzed. A total of 308 (10.7%) men had a history of cancer (non-prostate). Men with a cancer history had a higher number of PSA tests and more recent testing than men with no previous cancer history. On multivariable analysis, men who were previously diagnosed with cancer had a higher likelihood of undergoing PSA testing compared to men with no history of cancer (OR: 1.87, 95% CI 1.39-2.52, p < 0.0001). CONCLUSIONS: Our data suggest that men aged 55-69 with a history of cancer are more likely to undergo PSA testing than men with no cancer history.

Recurring cystitis cystica and cystitis glandularis masquerading as urothelial carcinoma.

We report a rare case of cystitis cystica and glandularis mimicking low-grade urothelial carcinoma that was found incidentally and treated with resection and fulguration via transurethral resection of bladder tumor (TURBT). When early recurrence was found on surveillance cystoscopy 3 months later, the patient was treated with repeat TURBT and intravesical gemcitabine. Surveillance cystoscopy 4 months later revealed cystitis cystica and cystitis glandularis yet again. We highlight the diagnosis and management of multiple early recurrences of cystitis cystica in this patient, particularly our treatment with gemcitabine and close surveillance.

Pesticides and Bladder Cancer: Mechanisms Leading to Anti-Cancer Drug Chemoresistance and New Chemosensitization Strategies.

Multiple risk factors have been associated with bladder cancer. This review focuses on pesticide exposure, as it is not currently known whether agricultural products have a direct or indirect effect on bladder cancer, despite recent reports demonstrating a strong correlation. While it is known that pesticide exposure is associated with an increased risk of bladder cancer in humans and dogs, the mechanism(s) by which specific pesticides cause bladder cancer initiation or progression is unknown. In this narrative review, we discuss what is currently known about pesticide exposure and the link to bladder cancer. This review highlights multiple pathways modulated by pesticide exposure with direct links to bladder cancer oncogenesis/metastasis (MMP-2, TGF-ß, STAT3) and chemoresistance (drug efflux, DNA repair, and apoptosis resistance) and potential therapeutic tactics to counter these pesticide-induced affects.

Financial Toxicity and Its Association With Prostate and Colon Cancer Screening.

BACKGROUND: The term "financial toxicity" or "hardship" is a patient-reported outcome that results from the material costs of cancer care, the psychological impacts of these costs, and the coping strategies that patients use to deal with the strain that includes delaying or forgoing care. However, little is known about the impact of financial toxicity on cancer screening. We examined the effects of financial toxicity on the use of screening tests for prostate and colon cancer. We hypothesized that greater financial hardship would show an association with decreased prevalence of cancer screening. METHODS: This cross-sectional survey-based US study included men and women aged ≥50 years from the National Health Interview Survey database from January through December 2018. A financial hardship score (FHS) between 0 and 10 was formulated by summarizing the responses from 10 financial toxicity dichotomic questions (yes or no), with a higher score associated with greater financial hardship. Primary outcomes were self-reported occurrence of prostate-specific antigen (PSA) blood testing and colonoscopy for prostate and colon cancer screening, respectively. RESULTS: Overall, 13,439 individual responses were collected. A total of 9,277 (69.03%) people had undergone colonoscopies, and 3,455 (70.94%) men had a PSA test. White, married, working men were more likely to undergo PSA testing and colonoscopy. Individuals who had not had a PSA test or colonoscopy had higher mean FHSs than those who underwent these tests (0.70 and 0.79 vs 0.47 and 0.61, respectively; P≤.001 for both). Multivariable logistic regression models demonstrated that a higher FHS was associated with a decreased odds ratio for having a PSA test (0.916; 95% CI, 0.867-0.967; P=.002) and colonoscopy (0.969; 95% CI, 0.941-0.998; P=.039). CONCLUSIONS: Greater financial hardship is suggested to be associated with a decreased probability of having prostate and colon cancer screening. Healthcare professionals should be aware that financial toxicity can impact not only cancer treatment but also cancer screening.

Does antithrombotic use enable earlier diagnosis of bladder cancer? A brief institutional assessment.

INTRODUCTION: Wallis et al (JAMA 2017) demonstrated use of antithrombotic medications (ATMs) is associated with increased prevalence of hematuria-related complications and subsequent bladder cancer diagnosis within 6 months. Stage of diagnosis was lacking in this highly publicized study. This study examined the association of ATM use on bladder cancer stage at the time of diagnosis. MATERIALS AND METHODS: We completed a retrospective chart review of patients with a bladder cancer diagnosis at our institution. Patient demographics and bladder cancer work up information were assessed. Patients were stratified based on use of ATMs at time diagnosis. Descriptive statistics were completed to identify association between ATM use and stage of bladder cancer diagnosis, as stratified by non-muscle invasive bladder cancer (NMIBC) versus muscle invasive bladder cancer (MIBC). RESULTS: A total of 1052 patient charts were reviewed. Eight hundred and forty-four were included and 208 excluded due to unavailability of diagnosis history. At diagnosis, 357 (42.3%) patients were taking ATMs. Patients on ATMs presented with NMIBC at similar rates as patients not taking ATMs (81.2% vs. 77.8%, p = 0.23). Subgroup analysis by ATM class similarly demonstrated no statistically significant differences in staging. CONCLUSION: While Wallis et al established that patients on blood thinners who present with hematuria are more likely to be diagnosed with genitourinary pathology, this factor does not appear to enable an earlier diagnosis of bladder cancer. Future study may assess hematuria at presentation (gross, microscopic), type of blood thinners, and low versus high risk NMIBC presentation.

Is there an association between a history of military service and cancer diagnosis? Results from a US national-level study of self-reported outcomes.

PURPOSE: To examine cancer prevalence in men with and without military service history, using national-level self-reported outcomes. METHODS: A cross-sectional survey-based US study, including men aged 18 and above from the Health Information National Trends Survey database between 2011 and 2014. The primary endpoint was self-reported cancer prevalence. Multivariable logistic regression analyses assessed the association of various covariates with the prevalence of cancer. RESULTS: A total of 4,527 men were analyzed, with 1,352 (29.9%) reporting a history of military service. Compared to men with no military service history, men with a military service history were older (median of 65 [IQR 56, 74] vs. 53 [IQR 41, 62] years, p < 0.0001), more commonly Caucasian (71.4% vs. 61.4%, p < 0.0001), born in the US (95.6% vs. 79.5%, p < 0.0001), attained higher education level and annual household income (p < 0.0001), and consisted of more smokers(58.3% vs. 44.5%, p < 0.0001). The age-adjusted comparison demonstrated a higher cancer prevalence in men with military service history (20.5% vs. 7.6%, p < 0.0001). Specifically, genitourinary, dermatological, gastrointestinal, and hematological cancers were generally more prevalent. Adjusting for all available confounders, multivariable models showed that military service history was associated with 1.56 (95% CI 1.20-2.03), and 1.57 (95% CI 1.07-2.31) increased odds of having any cancer, and specifically genitourinary cancer, respectively. CONCLUSIONS: Further research is needed to ascertain whether the association between military service and increased cancer diagnosis results from better screening programs or increased exposure to risk factors during military service.

Can post-treatment free PSA ratio be used to predict adverse outcomes in recurrent prostate cancer?

OBJECTIVES: To assess whether free PSA ratio (FPSAR) at biochemical recurrence (BCR) can predict metastasis, castrate-resistant prostate cancer (CRPC), and cancer-specific survival (CSS), following therapy for localised disease. PATIENTS AND METHODS: A single-centre retrospective cohort study (NCT03927287) including a discovery cohort composed of patients with an FPSAR after radical prostatectomy (RP) or radiotherapy (RT) between 2000 and 2017. For validation, an independent Biobank cohort of patients with BCR after RP was tested. Using a defined FPSAR cut-off, the metastasis-free-survival (MFS), CRPC-free survival, and CSS were compared. Multivariable Cox models determined the association between post-treatment FPSAR, metastases, and CRPC. RESULTS: Overall, 822 patients (305 RP- and 363 RT-treated patients and 154 Biobank patients) were analysed. In the RP cohort, a total of 272/305 (89.1%) and 33/305 (10.9%) had a FPSAR test incidentally and reflexively, respectively. In the RT cohort, 155/363 (42.7%) and 208/263 (57.3%) had a FPSAR test incidentally and reflexively, respectively. However, in the prospective Biobank RP cohort, FPSAR testing was done on all samples of patients diagnosed with BCR. A FPSAR cut-off of 0.10 was determined using receiver operating characteristic analyses in both the RP and RT cohorts. A FPSAR of <0.10 resulted in longer median MFS (14.8 vs 9.3 years and 14.8 vs 13 years, respectively), and longer median CRPC-free survival (median not reached vs 9.9 years and 20.7 vs 13.8 years, respectively). Multivariable analyses showed that a FPSAR of ≥0.10 was associated with increased metastasis in the RP cohort (hazard ratio [HR] 1.915, 95% confidence interval [CI] 1.241-2.955) and RT cohort (HR 1.754, 95% CI 1.112-2.769), and increased CRPC in the RP cohort (HR 2.470, 95% CI 1.493-4.088). Findings were validated in the Biobank cohort. CONCLUSIONS: A post-treatment FPSAR of ≥0.10 is associated with more aggressive disease, suggesting a potentially novel role for this biomarker.

Comparison of Magnetic Resonance Imaging and Transrectal Ultrasound Informed Prostate Biopsy for Prostate Cancer Diagnosis in Biopsy Naïve Men: A Systematic Review and Meta-Analysis.

PURPOSE: Multiparametric magnetic resonance imaging with informed targeted biopsies has changed the paradigm of prostate cancer diagnosis. Randomized studies have demonstrated a diagnostic benefit of clinical significance for targeted biopsy compared to standard systematic biopsies. We evaluated whether multiparametric magnetic resonance imaging informed targeted biopsy has superior diagnosis rates of any, clinically significant, high grade and clinically insignificant prostate cancer compared to systematic biopsy in biopsy naïve men. MATERIALS AND METHODS: Data were searched in Medline®, Embase®, Web of Science and Evidence-Based Medicine Reviews-Cochrane Database of Systematic Reviews from database inception until 2019. Studies were selected by 2 authors independently, with disagreements resolved by consensus with a third author. Overall 1,951 unique references were identified and 100 manuscripts underwent full-text review. Data were pooled using random effects models. The meta-analysis is reported according to the PRISMA statement and the study protocol is registered with PROSPERO (CRD42019128468). RESULTS: Overall 29 studies (13,845 patients) were analyzed. Compared to systematic biopsy, use of multiparametric magnetic resonance imaging informed targeted biopsy was associated with a 15% higher rate of any prostate cancer diagnosis (95% CI 10-20, p <0.00001). This relationship was not affected by the study methodology (p=0.11). Diagnoses of clinically significant and high grade prostate cancer were more common in the multiparametric magnetic resonance imaging informed targeted biopsy group (risk difference 11%, 95% CI 0-20, p=0.05 and 2%, 95% CI 1-4, p=0.005, respectively) while there was no difference in diagnosis of clinically insignificant prostate cancer (risk difference 0, 95% CI -3 to 3, p=0.96). Notably, the exclusion of systematic biopsy in the multiparametric magnetic resonance imaging informed targeted biopsy arm significantly modified the association between a multiparametric magnetic resonance imaging strategy and lower rates of clinically insignificant prostate cancer diagnosis (p=0.01) without affecting the diagnosis rates of clinically significant or high grade prostate cancer. CONCLUSIONS: Compared to systematic biopsy a multiparametric magnetic resonance imaging informed targeted biopsy strategy results in a significantly higher diagnosis rate of any, clinically significant and high grade prostate cancer. Excluding systematic biopsy from multiparametric magnetic resonance imaging informed targeted biopsy was associated with decreased rates of clinically insignificant prostate cancer diagnosis without affecting diagnosis of clinically significant or high grade prostate cancer.

A High Percent Free Prostate Specific Antigen in the Setting of Biochemical Recurrence after Radical Prostatectomy is Associated with Poorer Outcomes: A Validation Study Using Prospectively Collected Biobank Specimens.

PURPOSE: The role of percent free prostate specific antigen (%fPSA) in patients who have undergone radical prostatectomy and subsequently experienced disease relapse is unclear. We previously conducted 2 retrospective studies and found %fPSA 15 or greater in the setting of biochemical recurrence confers more aggressive disease. To validate that finding we used biobank specimens collected prospectively when patients were first diagnosed with biochemical recurrence. MATERIALS AND METHODS: Biobank specimens of patients with undetectable prostate specific antigen after radical prostatectomy and subsequent biochemical recurrence (prostate specific antigen 0.1 ng/ml or greater) were analyzed for %fPSA. Patients were stratified according to the %fPSA cutoff of 15. Univariable and multivariable logistic regression analysis was performed to predict covariates associated with a higher %fPSA. Cox proportional hazard models were performed to evaluate the prognostic effect of %fPSA on androgen deprivation therapy-free survival, metastasis-free survival, castration resistant-free survival and cancer specific survival. RESULTS: A total of 154 men were included in the study, of whom 126 (82%) had %fPSA less than 15 and 28 (18%) had %fPSA 15 or greater. Median followup for %fPSA less than 15 and %fPSA 15 or greater was 75 and 69 months, respectively. Patients with %fPSA 15 or greater had increased hazard of receiving androgen deprivation therapy (43% vs 25%, adjusted HR 2.40, 95% CI 1.12-5.11), metastatic disease (21% vs 7.9%, adjusted HR 4.10, 95% CI 1.11-15.2) and castration resistant prostate cancer (14% vs 4.0%, unadjusted HR 4.14, 95% CI 1.11-15.5) vs %fPSA less than 15, respectively. CONCLUSIONS: Patients with %fPSA 15 or greater were started on androgen deprivation therapy earlier, and they had progression to castration resistant prostate cancer and metastatic stage earlier. %fPSA 15 or greater in the setting of biochemical recurrence after radical prostatectomy is an indicator of a more aggressive disease. Unlike in the diagnostic setting, a higher %fPSA portends a worse clinical outcome.

Twitter and academic Urology in the United States and Canada: a comprehensive assessment of the Twitterverse in 2019.

OBJECTIVE: To provide the first comprehensive analysis of the Twitterverse amongst academic urologists and programmes in North America. METHODS: Using national accreditation and individual programme websites, all active urology residency programmes (USA and Canada) and academic Urology faculty at these programmes were identified. Demographic data for each programme American Urological Association [AUA] section, resident class size) and physician (title, fellowship training, Scopus Hirsch index [H-index] and citations) were documented. Twitter metrics (Twitter handle, date joined, # tweets, # followers, # following, likes) for programmes and physicians were catalogued (data capture: March-April 2019). Descriptive analyses and temporal trends in Twitter utilisation amongst programmes and physicians were assessed. Multivariable logistic regression was used to identify predictors of Twitter use. RESULTS: In all, 156 academic programmes (143 USA, 13 Canada) and 2214 academic faculty (2015 USA, 199 Canada) were identified. Twitter utilisation is currently 49.3% and 34.1% amongst programmes and physicians, respectively, and continues to increase. On multivariable analysis, programmes with 3-5 residents/year and programmes with a higher percentage of faculty Twitter engagement were more likely to have Twitter accounts. From a physician perspective, those with fellowship training, lower academic rank (Clinical Instructor, Assistant Professor, Associate Professor vs Professor) and higher H-indices were more likely to have individual Twitter accounts. CONCLUSION: There is a steady increase in Twitter engagement amongst Urology programmes and academic physicians. Faculty Twitter utilisation is an important driver of programme Twitter engagement. Twitter social media activity is strongly associated with academic productivity, and may in fact drive academic metrics. Within Urology, social media presence appears to be proportional to academic activity.

Gender-based psychological and physical distress differences in patients diagnosed with non-metastatic renal cell carcinoma.

OBJECTIVES: To analyze gender-based differences in distress symptoms in patients with non-metastatic renal cell carcinoma (RCC) at different stages of disease. METHODS: The Edmonton Symptom Assessment System-revised (ESAS-r) questionnaire includes a physical (PHSDSS) and a psychological distress sub-score (PDSS). The ESAS-r was used to measure psychological and physical distress symptoms in localized RCC patients in a major cancer referral center between 2014 and 2017 at four predefined time points: (a) diagnosis, (b) biopsy, (c) surgery, and (d) last follow-up. Results were gender stratified, and multivariable linear regression models were used to determine associations with increased sub-scores. RESULTS: Overall, 495 patients were included with 37.2% females. No significant gender differences were seen in mean age, relevant clinical parameters, and treatment. PDSS was significantly higher in females after diagnosis (8.5 vs. 5.1, p = 0.018), biopsy (8.9 vs. 4.1, p = 0.003), and surgery (6.5 vs. 4.4, p = 0.007), while being similar at the last follow-up. The multivariable model demonstrated a statistically significant association of female gender with higher PDSS after diagnosis (B = 3.755, 95% CI 0.761-6.750), biopsy (B = 6.076, 95% CI 2.701-9.451), and surgery (B = 1.974, 95% CI 0.406-3.542). PHSDSS was significantly higher in females after biopsy (10.0 vs. 5.7, p = 0.028) and surgery (8.6 vs. 6.1, p = 0.022). In the multivariable model, female gender conferred a higher PHSDSS only after surgery (B = 2.384, 95% CI 0.208-4.560). CONCLUSIONS: Gender-associated psychological distress differences exist in non-metastatic RCC patients throughout treatment, while dissipating at last follow-up. Emphasis should be placed on screening for distress symptoms and providing psychological support continuously, particularly for female patients.

How I Do It: Anticoagulation management for common urologic procedures.

Appropriate perioperative management of antithrombotic medications is critical; for every patient, the risk of bleeding must be balanced against individual risk of thrombosis. There has been a rapid influx of new antithrombotic therapies in the past 5 years, yet there is a lack of clear and concise guidelines on the management of anticoagulant and antiplatelet therapy during urologic surgery. Here we describe our approach to perioperative antithrombotic counseling, including the timing of stopping and restarting these medications. These practice guidelines have been developed in consultation with the Vascular Medicine service at our institution as well as after a review of current literature, and apply to common urologic procedures. Many cases are complex and require medical consultation or a multidisciplinary approach to management. We believe that by presenting our systematic method of antithrombotic management, including when to involve other discplines, we can increase knowledge and comfort amongst urologists in managing these medications in the perioperative period.

Simple frameshifts in minimally invasive surgery postoperative pain management significantly reduce opiate prescriptions.

INTRODUCTION: To evaluate the impact of an 'opt-in' non-narcotic postoperative pain regimen on narcotic utilization and patient-reported pain scores. MATERIALS AND METHODS: A prospective, non-blinded pre- and post-interventional trial was conducted, including a lead-in period for baseline evaluation. The intervention group received a new pain protocol prioritizing non-narcotic medications, an 'opt-in' requirement for opiates, and standardized patient education. Study outcomes included opiate prescription and utilization (measured in Morphine Equivalent Doses) and reported pain scores on postoperative day (POD) 1, discharge and follow up. RESULTS: At discharge, 70% fewer patients were prescribed any opioids (ARR: -0.7; p < 0.001); the amount prescribed was reduced by 95% (pre-intervention 69.3 mg versus post-intervention 3.5 mg, p < 0.001). Mean opioids used following discharge decreased by 76% (14.7 mg versus 3.5 mg, p = 0.011). In a subgroup analysis of robotic prostatectomies, there was a 95% reduction in mean opioids prescribed at discharge (64.6 mg versus 3.2 mg, p < 0.001) and 82% reduction in utilization over entire postoperative course (87.6 mg versus 15.7 mg, p = 0.001). There was no significant difference in pain scores between intervention groups at POD 1, discharge and follow up for patients (entire cohort and post-prostatectomy). CONCLUSION: A standardized pain protocol with 'opt-in' requirements for opiate prescription, emphasis on non-narcotic medications, and patient education, resulted in significant reductions in opioid use. Simple frameshifts in pain management can yield significant gains in the opioid epidemic.

Hospital-specific antibiograms and antibiotic prophylaxis for prostate biopsies: a reexamination of AUA recommendations.

INTRODUCTION: To assess whether standard American Urological Association (AUA) and other recommendations for prostate biopsy prophylaxis provide sufficient coverage of common urinary organisms responsible for post biopsy infections by comparing local antibiograms in Philadelphia-area hospitals. MATERIALS AND METHODS: De-identified culture results derived from antibiograms were collected from six academic and community hospitals in the Philadelphia region. Analysis specifically focused on four major bacterial causes of urinary tract infection following prostate biopsy (Escherichia coli (E. coli), Klebsiella pneumoniae, Proteus mirabilis and Enterococcus faecalis) along with commonly recommended antibiotics including fluoroquinolones (FQ's), trimethoprim/sulfamethoxazole, ceftriaxone, and gentamicin. RESULTS: Bacterial sensitivities to each antibiotic across institutions showed variation in E.coli sensitivities to FQs (p < 0.001), trimethoprim/sulfamethoxazole (p < 0.001), ceftriaxone (p < 0.001) and gentamicin (p < 0.001). Klebsiella pneumoniae and Proteus mirabilis exhibited similar variations. Sensitivity comparisons for Enterococcus faecalis was unable to be performed due to absent or incomplete data across institutions. CONCLUSION: Institutional antibiograms vary within our regional hospitals. Standardized recommendations for commonly used antibiotic prophylaxis such as fluoroquinolones may be inadequate for peri-procedural prostate biopsy prophylaxis based on local resistance patterns. Valuable information about the potential effectiveness of antibiotic prophylaxis for prostate biopsies can be found in local institutional antibiograms, and should be consulted when considering antibiotic prophylaxis for prostate biopsy procedures.
