To compare renal functional outcomes in patients with and without chronic kidney disease (CKD) to identify predictors of change in renal function after percutaneous nephrolithotomy (PCNL). We reviewed patients who underwent PCNL by a single surgeon over 3.5 years. Patients' pre- and post-operative Glomerular Filtration Rate (GFR) was calculated. Baseline GFR < 60 ml/min/1.73 m2 (stage ≥ 3 CKD) defined our CKD cohort. Patients' baseline renal function, comorbidities, stone parameters, and intra-operative variables were analyzed to determine the relationship with post-operative renal function after PCNL by multivariate analysis. 202 patients were analyzed. Mean follow-up time was 16 months. At baseline, 163 (80.7%) patients were free of CKD and 39 (19.3%) had CKD. Patients without CKD had an overall decrease in GFR from 105.6 to 103.3 ml/min/1.73 m2 (p = 0.494). 14/163 (8.6%) non-CKD patients experienced a significant decline in renal function after PCNL; 7/163 (4.3%) developed de novo CKD and 7 had a ≥ 30% decline in GFR. Patients with CKD had an overall increase in mean GFR post-operatively, from 47.3 to 54.0 ml/min/m2 (p = 0.067). Two in this cohort (5.1%) experienced a > 30% decline in renal function post-operatively. Age, gender, African American race, presence of comorbidities and pre-operative CKD were not significant predictors of renal function post-operatively on multivariate analysis. PCNL in this cohort appears GFR neutral in the setting of baseline CKD. CKD was not predictive of renal functional decline after PCNL. Given that stone disease carries a high recurrence rate and that CKD is associated with stone formers, further investigation into predictors of renal function change after PCNL is warranted.

Introduction and hypothesis: High vesicovaginal fistulas (VVF) in the setting of good apical support are best repaired via a transabdominal approach. Laparoscopic VVF repair was first reported in 1998. Several series of robot-assisted VVF repairs have since been published. The robot-assisted approach allows repair of high apical vaginal fistulas while avoiding the morbidity of laparotomy, shortening convalescence, and facilitating the use of omental interposition flaps. This video presents the technique for robot-assisted extravesical VVF repair utilizing a laparoscopically mobilized omental flap. Methods: A 43-year-old woman developed a VVF after a total abdominal hysterectomy for fibroids. Pre-operative CT urogram and office cystoscopy confirmed the diagnosis and ruled out ureteral involvement. She underwent a robot-assisted extravesical VVF repair utilizing a laparoscopically mobilized omental flap. Results: The surgery was uncomplicated, and the patient was discharged on post-operative day 1. A cystogram 2 weeks post-operatively revealed no evidence of a fistula. At 3 months follow-up, the patient denied any urinary incontinence. Conclusions: Robot-assisted extravesical VVF repair avoids the morbidity of a laparotomy, provides excellent exposure, and avoids a large cystotomy. It maintains vaginal length and allows for significantly better visualization compared with the transvaginal approach. This repair offers improved outcomes for certain patients depending on their history, anatomy, and the surgeon's experience. [ABSTRACT FROM AUTHOR]

Objective: To assess the relationship between individual nephrometry score (NS) constituents (RENAL) on perioperative outcomes and renal function of the surgical kidney in patients undergoing laparoscopic partial nephrectomy or robotic-assisted partial nephrectomy.Materials and Methods: Two hundred forty-five patients who underwent laparoscopic partial nephrectomy or robotic-assisted partial nephrectomy between 2005 and 2014 were retrospectively reviewed. Each renal mass' NS was calculated from preoperative computed tomography imaging. Multivariate regression analysis was used to evaluate the effect of NS variables on perioperative outcomes and change in overall renal function (as estimated by glomerular filtration rate) from preoperative to 1-year postoperative. A cohort analysis assessed the effect of NS variables on change in split renal function of the surgical kidney from pre- to postoperative based on nuclear medicine renal scintigraphy.Results: Tumor radius (R), endophytic nature (E), and nearness to collecting system (N) variables significantly and incrementally predicted a longer operative time and warm ischemia time. Overall renal function based on glomerular filtration rate was not affected by any NS variable. However, percent function of the surgical kidney by renal scintigraphy significantly decreased postoperatively as R and E values increased.Conclusion: R, E, and N were associated with significant changes in warm ischemia time and operative time. R and E were associated with a significant decrease in split renal function of the surgical kidney at 1 year after surgery but not with overall renal function. R, E, and N are the NS constituents most relevant to perioperative outcomes and postoperative differential renal function after partial nephrectomy. [ABSTRACT FROM AUTHOR]

Abstract: To examine how a low-carbohydrate diet affects cognitive performance, women participated in one of two weight-loss diet regimens. Participants self-selected a low-carbohydrate (n =9) or a reduced-calorie balanced diet similar to that recommended by the American Dietetic Association (ADA diet) (n =10). Seventy-two hours before beginning their diets and then 48h, 1, 2, and 3 weeks after starting, participants completed a battery of cognitive tasks assessing visuospatial memory, vigilance attention, memory span, a food-related paired-associates a food Stroop, and the Profile of Moods Scale (POMS) to assess subjective mood. Results showed that during complete withdrawal of dietary carbohydrate, low-carbohydrate dieters performed worse on memory-based tasks than ADA dieters. These impairments were ameliorated after reintroduction of carbohydrates. Low-carbohydrate dieters reported less confusion (POMS) and responded faster during an attention vigilance task (CPT) than ADA dieters. Hunger ratings did not differ between the two diet conditions. The present data show memory impairments during low-carbohydrate diets at a point when available glycogen stores would be at their lowest. A commonly held explanation based on preoccupation with food would not account for these findings. The results also suggest better vigilance attention and reduced self-reported confusion while on the low-carbohydrate diet, although not tied to a specific time point during the diet. Taken together the results suggest that weight-loss diet regimens differentially impact cognitive behavior. [Copyright &y& Elsevier]

Purpose: There is not yet satisfactory performance data comparing multiparametric MRI (mpMRI) versus biparametric MRI (bpMRI) for detecting prostate cancer (PCa), particularly in high-risk populations. We compared both protocols for detecting overall PCa and clinically significant PCa (CS-PCa; defined as Grade Group ≥ 2) in a multiethnic urban population. Methods: We retrospectively reviewed electronic medical record data from men who underwent image-guided fusion prostate biopsy (FB) between 2016 and 2021 at our institution. Patient characteristics, Prostate Imaging Reporting and Data System (PI-RADS) scores, and FB outcomes were analyzed based on MRI protocol. Multivariate mixed-effects logistic regression models were used to examine associations of bpMRI versus mpMRI for detecting overall PCa and CS-PCa in targeted lesions, among all patients and stratified by race/ethnicity. Results: Overall, 566 men (44.0% Non-Hispanic Black [NHB]; 27.0% Hispanic) with 975 PI-RADS 3–5 lesions on MRI underwent FB. Of these, 312 (55%) men with 497 lesions underwent mpMRI and 254 (45%) men with 478 lesions underwent bpMRI. On multivariate analyses among all men, the odds of detecting overall PCa (OR = 1.18, 95% CI: 1.05–3.11, p = 0.031) and CS-PCa (OR = 2.15, 95% CI: 1.16–4.00, p = 0.014) on FB were higher for lesions identified on bpMRI than mpMRI. When stratified by race/ethnicity, the odds of detecting overall PCa (OR = 1.86; p = 0.15) and CS-PCa (OR = 2.20; p = 0.06) were not statistically different between lesions detected on bpMRI or mpMRI. Conclusion: BpMRI has similar diagnostic performance to mpMRI in detecting overall and CS-PCa within a racially/ethnically diverse population. BpMRI can be utilized for evaluating suspected CS-PCa among NHB and Hispanic men. [ABSTRACT FROM AUTHOR]

Our goal was to assess the use and perceptions of complementary and alternative medicine (CAM) for kidney stones among a diverse, urban population. This was a cross-sectional study of patients treated for kidney stones in the Bronx, NY. We assessed demographic information, personal history of kidney stones, as well as knowledge and use of CAM for kidney stones. Patient demographics and responses were analyzed using chi-squared, t tests, and binomial logistic regression. 113 patients were surveyed. 90% identified as non-white, of whom 58% indicated Hispanic, 46% Latinx, and 23% Black. 56% of patients were born outside the United States. 56% of patients had heard of CAM for kidney stones and 44% had used CAM for kidney stones. The most common CAM were fruits (N = 42, 84%). Recurrent stone formers were more likely than first-time stone formers to have heard of CAM (68 vs 44% p = 0.013) and to have used CAM (56 vs 30%, p = 0.008). Those identifying as Hispanic were more likely to have both heard of and tried CAM for kidney stones (p = 0.036 and 0.022, respectively) compared to non-Hispanic patients. CAM are commonly used among our diverse, urban patient population. While some remedies are high in citrate and alkali (i.e., lemon, cranberry), others are high in oxalate (i.e., beets) and could potentially contribute to stone formation. These findings underpin the importance that medical providers educate themselves on the CAM used in their specific patient populations and discussing use with patients. Providers should aim to identify and reconcile therapeutics that oppose goals of treatment. [ABSTRACT FROM AUTHOR]

Objective: To perform a systematic review and meta-analysis comparing overall prostate cancer detection rate and clinically-significant prostate cancer detection rate between MRI-ultrasound image guided fusion biopsy (MRI-US FB) and cognitive biopsy (CB).Methods: A systematic review of Pubmed, EMBASE, MEDLINE, and Cochrane library databases was performed. Identified studies were assessed for clinical relevance and excluded based on a set of predefined criteria. Final articles included in the analysis comprised only prospective trials that compared CB vs. MRI-US FB in men with MRI-identifiable lesions (Prostate Imaging Reporting and Data System score 2+). Articles were reviewed for patient demographics, MRI protocol, and rates of overall and clinically significant prostate cancer detection by both modalities.Results: Nine studies were analyzed. A composite 1,714 men with mean age 64.6 years and mean PSA 8.2 ng/dL were reviewed. When comparing FB to CB, the odds ratio for overall and for clinically significant prostate cancer detection was 1.11 (95%CI 0.91-1.36, P = 0.30) and 1.13 (95%CI 0.89-1.44, P = 0.32), respectively. Heterogeneity among the studies was moderate but not significant for either overall (X2 = 14.67; I2 = 45%; P = 0.07) or clinically significant prostate cancer detection (X2 = 11.81; I2 = 49%; P = 0.07).Conclusion: MRI-US FB demonstrates a trend toward improved rates of prostate cancer detection compared to CB, although this is not statistically significant. Further comparative studies may help to further elucidate whether one of these modalities is superior over the other. [ABSTRACT FROM AUTHOR]

INTRODUCTION: We aimed to assess the effect of a shared institutional research database on medical students’ scholarly work, perceived research competency, and self-reported satisfaction. METHODS: An institutional inventory database was created on Google Sheets with a listing of available mentors and a description of their ongoing research projects. The inventory database was shared with interested students and faculty. Students who agreed to participate were surveyed pre- and post-inventory. Survey questions assessed student demographics, prior research experience, and their perception of research competency and satisfaction. The number of presentations, publications, and articles pre- and post-inventory were also abstracted. Survey responses were compared using the Mann-Whitney U test. RESULTS: A total of 20 students were surveyed pre-inventory and at a median followup of six months (5–7) post-inventory. There was a significant increase in scholarly presentations and publications post-inventory (p<0.05 for all). Furthermore, post-inventory, students reported feeling more confident in establishing an academic career, finding good mentors, managing their relationship with their mentor, managing professional challenges, and effectively showcasing themselves professionally and describing their research (p<0.05 for all). More than 65% of students agreed or strongly agreed that the database was easy to use, accessible, transparent, and would like a similar database created for other specialty departments. CONCLUSIONS: After performing mentorship-guided research through an institutional research database, medical students felt more confident in their ability to perform research and produced more scholarly work. Therefore, we recommend a research database be created across all institutional departments to foster interest in conducting research. [ABSTRACT FROM AUTHOR]

Among US men, most new prostate cancer cases are clinically localized and do not require imaging as part of staging workup according to guidelines. Two leading specialty societies promote stewardship of health resources by encouraging guideline-concordant care, thereby limiting inappropriate and obsolete imaging. However, imaging to stage low-risk prostate cancer remains high, as almost half of men with localized prostate cancer undergo wasteful imaging following diagnosis. We employed a theory-based approach, based on current evidence and data on existing practice patterns revealing that providers are the drivers to imaging decisions, to design an intervention to improve guideline -concordant prostate cancer staging imaging across populations. We conceptualized preliminary results using the theoretical domains framework and the behavior change wheel, frameworks used concurrently to investigate physicians′ behaviors and intervention design in various clinical settings. Through these 2 frameworks, we designed a theory-based, physician-focused intervention to efficiently encourage guideline-concordant prostate cancer imaging, prostate cancer imaging stewardship (PCIS). Prostate cancer imaging stewardship consists of interventions (clinical order check, academic detailing, and audit and feedback) implemented at the individual, facility, and system level to enact provider behavior change by enabling facilitators and appealing to physician motivation.

The article discusses research on current treatments for and long-term results associated with posterior urethral valves (PUVs). It references studies by several groups, including one by C. Holmberg and colleagues in the 2011 issue of "Journal of Urology." A retrospective assessment of the patients showed a total of 24 males with PUVs since 2007. Two of the three patients who were given renal transplantation experienced reflux into the transplanted kidney.

To perform a systematic review of the literature on plant-based and plant-forward diets and the prevention/treatment of the following common men's health conditions: prostate cancer (PCa), erectile dysfunction (ED), and benign prostatic hyperplasia (BPH). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses system criteria were utilized to search PubMed and Medline databases for the following search terms: "Diet (Mesh)" OR "Diet Therapy (Mesh)" AND "Prostatic Hyperplasia (Mesh)" OR "Prostatic Neoplasm (Mesh)" OR "Erectile Dysfunction (Mesh)." Articles in English published from 1989 to 2022 using human participants were analyzed, data summarized, and assessed for bias. Studies reporting on plant-based or vegetable-forward diets (Mediterranean) as an intervention were included. Cohort and cross-sectional studies using food frequency questionnaires or diet classification indices to quantify plant-based food intake patterns were included in the study. Ultimately, 12 PCa articles, 4 BPH articles, 6 ED articles, and 2 articles related to both BPH and ED were reviewed. Overall, the literature suggests plant-forward diets confer a protective effect on the men's health conditions reviewed. Evaluation of the literature on the impact of plant-forward diets on urologic conditions includes a heterogenous range of dietary patterns and study designs. The greatest amount of research has evaluated the application of plant-forward diets for PCa. While there is currently a lack of high-quality evidence for the use of plant-forward diets as prevention and/or treatment for PCa, ED, or BPH, reported outcomes suggest a consistent small beneficial impact alongside well-established benefits for common chronic conditions.

A retrospective chart review was conducted on patients surveilled for clinical non-muscle invasive bladder cancer (NMIBC) from 2013 to 2020 to determine the impact of urine cytology on clinical decision making during NMIBC surveillance. Less than 1% of urine cytology specimens collected during NMIBC surveillance impacted clinical management, none of whom had low-risk disease. The use of urine cytology for surveillance of low-risk NMIBC should continue to be strongly discouraged, as it did not change management in any such cases. Introduction: The use of urine cytology in the surveillance of non-muscle invasive bladder cancer (NMIBC) is widely variable in clinical practice. We studied the impact of surveillance urine cytology on clinical decision making during NMIBC surveillance. Methods: A retrospective chart review was conducted on patients surveilled for clinical NMIBC from 2013 to 2020 with at least one follow-up cytology result after diagnosis. Patients were classified into risk categories according to American Urological Association (AUA) NMIBC guidelines. Data were obtained regarding tumor recurrence pathology and the frequency and findings of surveillance cystoscopies and urine cytologies. Positive (suspicious, malignant) and negative (atypical or negative for malignant cells) cytology results were correlated with cystoscopy and pathology findings when obtained within 3 months of the cytology specimen to determine if cytology impacted plan of care. Results: Two hundred fourteen patients with NMIBC were followed for a median of 34 months, with 1045 urine cytologies collectively obtained over the surveillance period. There were no positive urine cytologies among patients with low-risk NMIBC; therefore, cytology did not change management in this cohort. The potential for cytology to escalate management for patients of any risk group (ie, positive cytology in the absence of positive cystoscopy or pathology findings) occurred in 30 (2.9%) cases. However, clinical decision making was only altered in 4 cases (0.4% of all cytologies). Conclusions: Less than 1% of urine cytology specimens collected during NMIBC surveillance impacted clinical management, none of whom had low-risk disease. The use of urine cytology for surveillance of low-risk NMIBC should continue to be strongly discouraged, as it did not change management in any such cases. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this review is to highlight the unique factors that predispose geriatric patients to nephrolithiasis and to compare the utility and efficacy of surgical techniques in this specific patient population. Methods: PubMed and EMBASE databases were reviewed, and studies were organized according to surgical treatments. Results: Few prospective studies exist comparing kidney stone removal in the elderly to younger cohorts. In addition, various age cut-offs were used to determine who was considered elderly. Most studies which analyzed Percutaneous Nephrolithotomy (PCNL) found a slightly higher rate of minor complications but comparable stone free rate and operative time. For ureteroscopy (URS) and extracorporeal shockwave lithotripsy (ESWL), there were minimal complications observed and no difference in clinical success in the elderly. All surgical techniques were presumed to be safe in the elderly and most found no difference in stone-free rates. Conclusions: Unique attributes of the geriatric population contribute to stone formation and must be considered when determining appropriate management modalities. This review provides an overview of the utility and efficacy of PCNL, URS and ESWL in the elderly, as well as a porposed algorithm for management in this population. [ABSTRACT FROM AUTHOR]

To design and implement a simple electronic medical record-based ureteral stent tracker. To assess its impact on stent dwell time and stent-related complications. Patients with stents placed 12 months before and 6 months after stent tracker implementation were identified at 3 urban hospitals. Those with stents-on-strings and intentional chronic indwelling stents (greater than 90 days) were excluded. Patient demographics, stent characteristics (eg, indication, string, dwell time), and clinical outcomes (eg, positive urine cultures, complications) were reviewed and compared between pre- and posttracker cohorts. A 12-question usability survey was administered to surgical nurses to assess usability. A total of 323 stents (173 pre- and 150 posttracker) were placed in 217 patients. The prestent tracker cohort had a longer mean dwell time (pre: 40.9 ± 59.1 days vs post: 28.8 ± 22.0 days, P =.02) and a higher retention rate >90 days (pre: 8.1% [14/173] vs post: 1.3% [2/150], P =.005). The 2 cohorts had no significant differences in positive urine culture rates, patient phone calls to providers, stent-related emergency department visits, or hospitalizations. The usability survey showed that 86.4% of surgical nurses found the tracker to be user-friendly and 95.5% reported that it added less than 1 minute of work per procedure. Implementation of an electronic medical record-based ureteral stent tracker decreased average stent dwell time and frequency of retained stents. Surgical nurses reported the tracker to be user-friendly and convenient. Stent trackers can improve the efficiency of postoperative removal of indwelling ureteral stents. [ABSTRACT FROM AUTHOR]

To evaluate patient understanding of risks, benefits, and alternatives (R/B/A) prior to urological procedures using the teachback method. Using a preprocedural phone interview, patients recalled general knowledge and R/B/A of a scheduled procedure. A scoring system compared patient responses to a standardized R/B/A list to analyze the level of understanding, graded as incomplete (<25%), partial (25-75%), or complete (>75%). Following the interview, additional education was provided if understanding was inadequate, and patients were queried regarding their satisfaction. Patients (n = 99) comprised 46% women; 32% Spanish speaking; Mean age was 64 ± 10.9 years. Procedures included were: intravesical botulinum toxin injection (24), mid-urethral sling (9), colpocleisis (4), prostate biopsy (24), ureteroscopy (16), transurethral resection prostate (11), transurethral resection bladder tumor (11). Across all procedures, the average percent of risks identified was 12%, benefits 63%, and alternatives 35%. No patients had complete understanding, but most had partial (73.7%). Patients had significantly higher level of understanding if they were female (P = 0.02), underwent the same procedure previously (P < 0.01) or any surgery within a year (P = 0.02), and were undergoing an in-office procedures (P = 0.03). After the teachback interview, most patients (90%) were satisfied with their understanding. In our cohort, patient understanding was alarmingly incomplete and there was substantial benefit in pre-procedural interviews. Our findings highlight the need for improvement in patient education prior to surgery and offers a potential solution using a teachback-based telephone interview. [ABSTRACT FROM AUTHOR]

Objective: To evaluate practice patterns of post-ureteroscopy (URS) imaging, to assess predictors of imaging order, type and completion, and to analyze impact on patient management.Methods: We conducted a retrospective review of patients who underwent URS for nephrolithiasis at a single institution between May, 2020 to May, 2021. Patient demographic, clinical and operative characteristics were reviewed, and surgeons' years in practice. Post-URS imaging studies less than 6 months post-operative were reviewed. Changes in patient management were defined as additional imaging tests ordered or subsequent unplanned surgery. Patient, provider and surgical variables were compared between those who had imaging ordered and those who did not.Results: A total of 289 patients underwent URS. About 234 (81.0%) had post-operative imaging ordered; 147 (62.8%) completed them. Baseline demographics, stone and surgical variables were similar among those who did and did not have imaging ordered and among patients who completed imaging and did not. Pre-operative hydronephrosis was associated with ordering of post-operative imaging (OR = 4.08, P = .01). Urologists in practice less than 5 years were more likely to order post-operative imaging compared to those in practice for more than 5 years (<5: 90.6%, 15+: 53.7%; P <.001). Management changed for 52 of 147 (35.4%) patients who completed imaging; additional imaging was ordered for 38 patients (25.9%) and a second, unplanned surgery was performed for 14 (9.5%).Conclusion: The main predictive factor of ordering post-URS imaging was surgeons' time in practice and pre-operative hydronephrosis. Post-operative imaging changed management in 35.4% of patients. We recommend the development of guidelines encouraging routine imaging for patients following ureteroscopy. [ABSTRACT FROM AUTHOR]

To review the current and newer, alternative methods for evaluating lymph nodes for tumor involvement in bladder cancer as relapse rates for organ-confined disease remain high despite improvements in surgical technique, suggesting the possibility of understaging. To propose a research agenda based on these findings. A PubMed literature search was performed to identify studies examining the prognostic implications of and outcomes associated with lymph node involvement in bladder cancer as well as those that utilized newer methodologies to identify the possibility for metastatic disease. Lymph node involvement remains one of the strongest predictors of clinical outcome in bladder cancer. Histologic and molecular techniques for identification of lymph node metastasis provide a sensitivity and specificity equal to if not higher than standard pathologic evaluation. Further research into this field would help to elucidate the potential utility of these techniques with regard to proper staging and potential relevance to clinical outcomes. [ABSTRACT FROM AUTHOR]

Objective: To investigate the financial toxicity (FT) related to kidney stone treatment.Methods: We performed a cross-sectional cohort study with multi-institutional in-person and online cohorts of stone formers.  Participants were surveyed using the validated COST tool (COmprehensive Score for financial Toxicity). The maximum score is 44 and lower scores indicate increased FT. "Moderate FT" was defined by COST scores between 25 and 14 points and "severe FT" for scores <14. Descriptive statistics, X2 tests, T tests, Spearman correlation, and logistic regression were performed using SPSS v28.Results: Two hundred and forty-one participants were surveyed, including 126 in-person participants and 115 online. A total of 60% of participants reported at least moderate FT (COST score <26) and 26% reported severe FT (COST score <14). Patients who reported moderate to severe FT were younger than those with low FT by a median difference of 8 years (95%CI = 4, 12). There was a significant correlation between out-of-pocket expense and COST scores, such that as out-of-pocket expenses increased, COST scores decreased, (Spearman's rho =-0.406, P = <.001). Participants with moderate to severe FT tended to miss more workdays (P = .002), and their caretakers tended to miss more workdays (P = .007) due to their stone disease.Conclusion: Most participants reported moderate to severe FT. As prior studies have shown that patients with "moderate FT" employ cost-coping strategies (i.e., medication rationing) and those with "severe FT" have worse health outcomes, urologists need to be sensitive to the financial burdens of treatment experienced by such patients undergoing kidney stone treatment.

Introduction: Opioids are often used to manage postoperative pain. Non-narcotic alternatives have increasingly been used to reduce opioid usage. We conducted an open-label randomized non-inferiority clinical trial to compare non-opioid to opioid therapy for pain management after nephrolithiasis surgery. Methods: Patients undergoing elective ureteroscopy or percutaneous nephrolithotomy between July 2018 and May 2021 were randomized to receive ketorolac (non-opioid) or oxycodone-acetaminophen (opioid). Each patient was surveyed one week postoperatively to assess pain outcomes. Patient demographics, surgical variables, number of pills used, constipation, and adverse events were also assessed. We evaluated whether non-opioid analgesia was non-inferior to opioid analgesia for postoperative pain, assuming a non-inferiority margin of 1.3 in pain score between groups. Results: Analyses were based on 90 patients with postoperative pain data: 44 in the ketorolac group and 46 in the oxycodone-acetaminophen group. The groups were similar regarding demographics, type of surgery, ureteral stent placement, and stone burden. Non-inferiority of non-opioids compared to opioids was demonstrated for all outcomes. At follow-up, the average pain scores were 3.20 ± 1.94 (SD) in the non-opioid group and 4.17 ± 1.84 in the opioid group (difference = − 0.96; 95% CI: − 1.76, − 0.17, p = 0.018). The mean proportions of unused pills were similar between groups (p = 0.47) as were rates of constipation (p = 0.32). Conclusions: Non-opioid analgesia was non-inferior to opioid analgesia in pain management after kidney stone surgery. This trial contributes to the evidence that non-opioid analgesics should be considered an effective option for pain management following non-invasive urologic procedures. [ABSTRACT FROM AUTHOR]

Objective: To study implicit and explicit gender biases in YouTube videos describing common urologic conditions based on language patterns, speaker gender, and speaker profession.Methods: Using a Boolean search, the top 30 videos for benign prostatic hyperplasia (BPH), kidney stones, urinary tract infections (UTIs), overactive bladder (OAB), erectile dysfunction (ED), and pelvic organ prolapse (POP) were retrieved. Using the Linguistic Inquiry and Word Count program (LIWC) software, video transcripts were analyzed for 16 word categories and compared by speaker gender and urology topic to assess for bias.Results: OAB and POP had the least view counts and subscribers; kidney stone and ED videos had the most. Student education channels were more likely to feature male than female speakers (19 male vs. 6 female, P=0.01). A significant difference was noted between speaker gender in BPH (25 male vs. 4 female, P<0.001), OAB (4 male vs. 22 female, P<0.001), and POP (6 male vs. 23 female, P<0.001) videos. When examining linguistic patterns with the LIWC program, female speakers were more likely to mention personal concerns and use tentative words when speaking alone compared to males.Conclusions: Gender bias exists in YouTube videos concerning common urologic conditions. We must be mindful of how information is distributed in order to minimize the perpetuation of gender stereotypes that are common in medicine. Awareness of these patterns and biases should encourage Urologists to proactively consider how they present themselves and how they reference the conditions they present in social media outlets.

Purpose: This study aimed to investigate the relationship between self-reported food security and kidney stone formation. Methods: Data were collected from the National Health and Nutrition Examination Survey (NHANES), a database representative of the United States population. Food security status was assessed using the US Household Food Security Survey Module: Six-Item Short Form. Characteristics of patients were compared using the Chi-square test and the student t-test. Multivariate logistic regression was performed using a multi-model approach. Results: We analyzed 6,800 NHANES survey respondents. 37.2% of respondents were categorized as having "low food security" (scores 2–4) and 24.0% having "very low food security" (scores 5–6). 8.4% of respondents had a history of kidney stones. We found that people with very low food security had a 42% increased likelihood of developing kidney stones compared to those with high or marginal food security, after controlling for race, age, and comorbidities (OR 1.42; 95% CI 1.01–1.99). Between the different food security groups, no significant differences were observed in age, race/ethnicity, body mass index, gout history, osteoporosis history, or coronary artery disease history. Lower food security was associated with slightly younger age (< 1 year difference, p = 0.001), higher poverty-income ratio (p = 0.001), and many comorbidities, including kidney stones (p = 0.007). Conclusion: Our study provides evidence for an association between food access and the risk of kidney stone disease. Given these findings, food insecurity should be investigated as a modifiable risk factor for the development of kidney stone disease. [ABSTRACT FROM AUTHOR]

Objective: To analyze Twitter engagement in response to the urology match during the COVID-19 pandemic.Methods: Tweets containing the hashtags "#uromatch" or "#AUAmatch" during the 2021 and 2022 Match Week were reviewed. Date, author type and number of followers, general content, and engagement with each Tweet was collected. Differences in engagement between author type and content were analyzed using the Kruskal-Wallis H test. Tweet characteristics were compared between the 2021 and 2022 Match Cycles using the Chi-Square test.Results: There were 656 Tweets in total, with 272 (43.5%) from 2021 and 353 (56.5%) from 2022. Medical students' and residency programs' posts received significantly more Tweet engagement than those by residents/fellows, attendings, or the AUA (P <.05). Tweets focusing on announcing a new residency class and personal announcements of match results received significantly more engagements than other content categories (P <.05). In 2022, there was a significantly higher percentage of Tweets about advice for unmatched applicants (2.2 vs 12.5; P <.001), match statistics (0.4 vs 2.9; P = .028) and focus on underrepresented groups in urology (0.7 vs 3.4; P = .029).Conclusion: The Twitter response to the urology match between 2021 and 2022 mirrored the increase in competitiveness, with greater participation and an increasing focus on the difficulty of matching. During Match Week, Twitter is a readily available source of information for programs, matched students, and unmatched students alike. As we continue to embrace virtual platforms, we believe that Twitter will remain a major source of match-related information and can be an instrumental tool for broader networking in our field.

Objective: To perform a systematic review of mixed epithelial stromal tumor of the seminal vesicle (SV) to characterize the diagnosis and treatment of this rare condition.Methods: "Seminal vesicle mixed epithelial stromal tumor" OR "seminal vesicle cystadenoma" were searched on PubMed/MEDLINE for relevant articles through 6 September 2021. Articles were eligible if they were in English, accessible via our university library services, and if the abstract was concordant with the content of the publication. Reference lists of included articles were reviewed to identify additional relevant articles.Results: In total, 66 articles were identified, of which 34 (N = 36 patients) were included. The most common presenting symptoms were lower urinary tract symptoms (33%, 12/36), dysuria (22%, 8/36), lower abdominal pain (17%, 6/36), and hematuria (17%, 6/36). However, there were eight cases (23%, 8/36) of asymptomatic incidental SV tumors. A biopsy was performed in 47% of cases (17/36), of which 53% (9/17) showed benign findings, 29% (5/17) were inconclusive, and 18% (3/17) SV cystadenoma. Surgical resection was performed using open (57%, 20/35), laparoscopic (26%, 9/35), or robotic (17%, 6/35) techniques. The majority (94%, 34/36) of the SV tumors were low-grade. Long-term follow-up was reported for 15 patients in which two patients (13%, 2/15) had tumor recurrence.Conclusion: High rate of inconclusive biopsy of SV tumors suggests that routine biopsy is of questionable utility. Surgical excision frequently relieves symptoms and confirms accurate pathologic diagnosis. After tumor removal, patients should be surveilled with cross-sectional imaging of the pelvis given the possibility of tumor recurrence. [ABSTRACT FROM AUTHOR]

Objective: To analyze the National Hospital Ambulatory Medical Care Survey (NHAMCS) database to determine geographic and temporal trends, as well as variables associated with the likelihood of receiving an opioid prescription for urolithiasis in United States (US) emergency departments (EDs).Materials and Methods: All ED visits for urolithiasis between 2006 and 2018 in the NHAMCS database were analyzed. Age, race/ethnicity, insurance status, ED provider credentials, geographic region, and urban vs rural hospital status were extracted. Linear regression was used to examine overall/regional trends in opioid prescriptions over time. Logistic regression was used to estimate factors associated with higher odds of receiving opioids.Results: Fourteen million visits were analyzed, of which, 79.1% (11.0 million) received an opioid prescription. From 2014 to 2018 there was a decline of 3.65%/year of the proportion of visits receiving an opioid prescription (R2 = 0.86, P = .008). Non-Hispanic Black race was associated with a lower chance of receiving opioid prescription (OR = 0.57, P = .02) compared to Non-Hispanic Whites (NHW). Midwestern hospitals had higher odds of opioid prescription compared to the Northeast (OR = 2.05, P = .006). Rural hospitals had lower odds of opioid prescription compared to urban hospitals (OR = 0.62, P = .02).Conclusion: Opioid prescriptions for patients presenting with urolithiasis to the ED have steadily declined from 2014 to 2018, except in the Midwest. NHW race, Midwest region, and urban EDs increase the likelihood of receiving opioids. Continued efforts encouraging non-opioid alternatives for urolithiasis are essential, specifically in Midwestern EDs, to mitigate the ongoing opioid epidemic in the US. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate the quality of information regarding erectile dysfunction (ED) treatment on YouTube and TikTok. The term "erectile dysfunction" was searched on YouTube and TikTok in July 2021. The first 50 videos on each platform that met inclusion were included. Videos were sorted as reliable or unreliable based on accuracy of video content. Quality of information was evaluated using Patient Education Materials Assessment Tool (PEMAT) and 5‐point modified DISCERN. TikTok videos were shorter (0.4 minutes vs. 5.2 minutes, p < 0.001) and had more likes (2294 vs. 1000, p = 0.005), views per month (17,281 vs. 3521, p < 0.001) and subscribers/followers (97,500 vs. 23,000, p = 0.016) than YouTube videos. TikTok videos were less reliable than YouTube videos (TikTok 5/50 [10%] vs. YouTube 21/50 [42%], p < 0.001). YouTube mentioned more about phosphodiesterase type 5 inhibitors (32% vs. 10%, p = 0.007), while TikTok mentioned more about alternative supplements (36% vs. 4%, p < 0.001). YouTube had a higher DISCERN (1.99 vs. 0.98, p < 0.001) and PEMAT actionability scores (64.2% vs. 54.0%, p = 0.039) when compared to TikTok. YouTube videos were of higher quality than TikTok videos. Nevertheless, YouTube had a considerable amount of unreliable information. We recommend a collaborative effort from the medical community to improve information regarding ED treatment on YouTube and TikTok. [ABSTRACT FROM AUTHOR]

We examined the independent and combined effects of body mass index/obesity and diabetes mellitus in relation to the NCCN prostate cancer (PCa) risk groups in a racially-diverse cohort of men from an urban medical center. We found that obesity and diabetes were associated with high-risk PCa; however, most of the association was driven by obesity. Introduction: Obesity and diabetes mellitus (DM) have been associated with prostate cancer (PCa) risk, but data examining their combined effects on aggressive PCa are sparse, particularly among non-Hispanic Black and Hispanic men. We investigated the associations of obesity and DM in relation to National Comprehensive Cancer Network (NCCN) PCa risk groups in a racially-diverse patient population. Patients and Methods: We abstracted demographic and clinical data from men who underwent radical prostatectomy at our institution between 2005 and 2019. Patients were classified into three NCCN PCa risk-groups: low, intermediate and high-risk. Logistic regression models were used to examine the independent and combined associations of body mass index (BMI)/obesity and DM with risks of intermediate and high-risk PCa, adjusting for age and race/ethnicity. Results: A total of 1303 men with PCa (average age 60 ± 6.9 years) were analyzed. The majority were non-Hispanic Black (N = 493, 38%) or Hispanic (N = 407, 31%). The prevalence of obesity (BMI = 30 kg/m 2) and DM was 29.3% (N = 382) and 28.3% (N = 369), respectively. In multivariate analyses, obesity was independently associated with an odds ratio (OR) = 2.21 of high-risk PCa (95% CI: 1.28-3.81), while DM was associated with an OR = 1.49 (95% CI: 1.05-2.11) of intermediate-risk PCa. Compared to non-obese men without diabetes, men with BMI = 30 and DM had increased risks of both intermediate (OR = 1.93; 95% CI 1.12-3.43) and high-risk PCa (OR = 2.40; 95% CI 1.22-4.73). Interestingly, most of the association of highrisk PCa was driven by obesity. Conclusion: In this multiethnic population both obesity and DM were independently associated with intermediate- and high-risk PCa; however, most of the association for high-risk cancer was driven by obesity. Our results corroborate findings that obesity increases the risk of aggressive PCa; however, results regarding DM need to be confirmed in other large multiethnic populations. [ABSTRACT FROM AUTHOR]

Objective: To perform a systematic review and a retrospective cohort analysis evaluating the rates of surgical downgrading of prostate cancer (PCa) from biopsy (PBx) to radical prostatectomy (RP), and their association with biochemical recurrence (BCR) in a multiethnic population. Methods: A systematic review of PubMed and other databases was performed. We included retrospective studies evaluating the relationship between surgical downgrading and BCR-free survival. Data regarding Gleason score (GL) downgrading were abstracted from the articles and categorized as follows: GL8-10 to GL7, GL7 to GL6, and GL 7(4 + 3) to GL7(3 + 4). We also performed a retrospective cohort review of patients who underwent RP at our institution from 2005 through 2020. Kaplan–Meier survival analysis and Cox proportional hazards models were used to compare BCR among downgraded versus non-downgraded men. Results: Systematic review yielded 137 abstracts; of these, 36 full-texts were reviewed, 8 of which were included in our systematic review. Despite substantial variability, all showed that GL at RP is one of the most important factors of BCR-free survival. A total of 1,484 men with PCa were analyzed from our institution. On multivariate analysis, GL7 to GL6 downgrading (HR = 0.50, p = 0.022) and GL8-10 to GL7 downgrading (HR = 0.42, p = 0.011) were associated with reduced risk of BCR when compared to men with GL7 and GL8-10 concordance, respectively. However, GL7(4 + 3) to GL7(3 + 4) downgrading was not significantly associated with reduced BCR (HR = 0.56, p = 0.12), when compared to GL7(4 + 3) concordance, although HR was similar. Conclusion: Surgical downgrading at RP was associated with a reduced risk of BCR compared to GL concordant disease, and these findings have been validated within our multiethnic population. Pathologic downgrading at the time of RP may be a more useful predictor of subsequent BCR in comparison to that associated with GL concordant pathology. [ABSTRACT FROM AUTHOR]

We studied the effects of switching antipsychotic drug-treated patients with schizophrenia or bipolar disorder who evidenced adverse metabolic side effects as indicated by a triglyceride/high-density lipoprotein ratio (TG/HDL) ≥ 3.5 to aripiprazole (ARIP; 5–30 mg/day, n = 24) or ziprasidone (ZIP; 40–160 mg/day, n = 28). Anthropometric and metabolic measures, psychopathology, quality of life and motor adverse effects were assessed over a 52-week period with evaluations at baseline, 6, 12, 26 and 52 weeks. There were statistically significant improvements in body weight, body mass index (BMI), TG, HDL and TG/HDL which did not differ between treatments. However, numerous secondary measures including weight and BMI, and the proportion of patients who lost ≥ 7% or who no longer met criteria for obesity, favored ZIP over ARIP. Decreases in total cholesterol and increases in HDL-cholesterol also favored ZIP. On the other hand, decreases in TG/HDL ratio and reduction in HgbA1c favored ARIP. There were no significant time or group × time interaction effects for most psychopathology measures; however, Global Assessment of Functioning Scores favored ARIP at 6 and 12 months. We conclude that switching patients with evidence of metabolic side effects to either ARIP or ZIP may be beneficial for some, but not all metabolic measures, with minimal risk of worsening of psychopathology and possibly some benefit in that regard as well.

Objective: To examine differences between telephone and video-televisits and identify whether visit modality is associated with satisfaction in an urban, academic general urology practice.Methods: A cross sectional analysis of patients who completed a televisit at our urology practice (summer 2020) was performed. A Likert-based satisfaction telephone survey was offered to patients within 7 days of their televisit. Patient demographics, televisit modality (telephone vs video), and outcomes of the visit (eg follow-up visit scheduled, orders placed) were retrospectively abstracted from each chart and compared between the telephone and video cohorts. Multivariate regression analysis was used to evaluate variables associated with satisfaction while controlling for potential confounders.Results: A total of 269 patients were analyzed. 73% (196/269) completed a telephone televisit. Compared to the video cohort, the telephone cohort was slightly older (mean 58.8 years vs. 54.2 years, P = .03). There were no significant differences in the frequency of orders placed for medication changes, labs, imaging, or for in-person follow-up visits within 30 days between cohorts. Survey results showed overall 84.7% patients were satisfied, and there was no significant difference between the telephone and video cohorts. Visit type was not associated with satisfaction on multivariable analyses, while use of an interpreter [OR:8.13 (1.00-65.94); P = .05], labs ordered [OR:2.74 (1.12-6.70); P = .03] and female patient gender [OR:2.28 (1.03-5.03); P = .04] were significantly associated with satisfaction.Conclusion: Overall, most patients were satisfied with their televisit. Additionally, telephone- and video-televisits were similar regarding patient opinions, patient characteristics, and visit outcome. Efforts to increase access and coverage of telehealth, particularly telephone-televisits, should continue past the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

Introduction: We compared clinicopathologic characteristics and outcomes of radical nephrectomy (RN) for small renal masses (SRM) in patients with end-stage renal disease (ESRD) before or after transplant at a high-volume urologic and transplant center. Methods: We performed a retrospective review of patients with ESRD (glomerular filtration rate [GFR] <15 mL/min) who underwent RN for suspected malignant SRM from 2000-2018. Group 1 consisted of patients who underwent RN after transplant; group 2 underwent RN prior to transplant, and group 3 underwent RN without subsequent transplant. Dominant tumor size and histopathologic characteristics, recurrence, and survival outcomes were compared between groups. Chi-squared and Mann-Whitney U tests were used to compare categorical and continuous baseline and histopathologic characteristics, respectively. Univariate analysis and log rank test were used to compare RCC recurrence rates. Results: We identified 34 nephrectomies in group 1, 27 nephrectomies in group 2, and 70 nephrectomies in group 3. Median time from transplant to SRM radiologic diagnosis in group 1 was 87 months, and three months from diagnosis to nephrectomy for all groups. There were no statistically significant differences between pathologic dominant mass size, histologic subtype breakdown, grade, or stage between the groups. Rates of benign histology were similar between the groups. Univariate analysis did not reveal a statistically significant difference in recurrencefree survival between the groups (p=0.9). Conclusions: Patients undergoing nephrectomy before or after transplant for SRM have similar indolent clinicopathologic characteristics and low recurrence rates. Our results suggest that chronic immunosuppression does not adversely affect SRM biology. [ABSTRACT FROM AUTHOR]

Objective: To determine if gender bias exists at the plenary sessions of the American Urological Association (AUA) annual conference by evaluating variations in the use of a professional title (PT) during speaker introductions at these sessions.Methods: We retrospectively reviewed video archives of all plenary sessions from the AUA annual conferences from 2017 to 2019. Videos that included both plenary introducer and speaker were included for analysis. The following data were collected: conference year, gender, and academic rank of "introducer" and of "speaker," and use of PT (ie, doctor) during speaker introduction. Variations in use of PT for introductions of speakers based on gender of introducer and of speaker were analyzed by chi-square tests.Results: Four hundred and fourteen videos were reviewed; 195 (47%) with a composite 622 introducer/speaker pairs were reviewed and analyzed. Only 8.7% of introducers and 14.6% of speakers were female (Table 1). Overall, there was no difference in the use of PT for introductions of female vs male speakers (61.5% vs 60.8%, P = 0.90). However, male speakers were more likely to be introduced as doctor when introduced by a female vs a male (75.60% vs 59.60%, P = 0.04). Female speakers were equally likely to be introduced as doctor regardless of introducer gender.Conclusion: Men represented the majority of presenters and speakers in the plenary session at AUA meetings. However, there is not a significant difference in the use of PT for AUA plenary speaker introductions based on gender. [ABSTRACT FROM AUTHOR]

• CFB and IGFB offer similar detection rates of cs-CaP in a multiethnic population. • For cs-CaP, CFB and IGFB had similar rates of concordance to systematic biopsy. • For overall CaP, CFB had higher rates of discordance than IGFB. Transrectal ultrasound-guided prostate biopsy remains the most used method for the detection of prostate cancer. We recently reported that detection of clinically significant prostate cancer (cs-CaP) using image-guided fusion biopsies (IGFB) varied by race/ethnicity, which calls for further comparison between cognitive fusion biopsy (CFB) and IGFB among non-Hispanic black and Hispanic populations. Therefore, the aim of our study is to compare the rates of detection of cs-CaP and overall CaP by CFB and IGFB in a multiethnic community. We performed a retrospective, cross-sectional review of men who underwent MRI-transrectal ultrasound-guided prostate biopsy at our diverse, urban academic medical center. Agreement and discordance between fusion biopsies and systematic biopsies for detection of cs-CaP and overall CaP were determined using Kappa statistics. Univariate and multivariate mixed-effects logistic regression models were used to find associations between fusion modalities and prostate cancer detection. In total, 710 men underwent fusion prostate biopsies between December 2015 and June 2021. Upon univariate and multivariate logistic regression analysis, there was no significant association between IGFB vs. CFB and risk of overall CaP (OR = 0.66, 95% CI: 0.36–1.21, P = 0.18) or cs-CaP (OR = 0.57, 95% CI: 0.30–1.08, P = 0.09). We found moderate agreement between fusion and systematic biopsies for both CFB (κ = 0.56) and IGFB (κ = 0.52) in cs-CaP. CFB and IGFB offer similar detection rates of cs-CaP in a multiethnic population. CFB represents an effective and accessible means of accurately diagnosing prostate cancer. [ABSTRACT FROM AUTHOR]

The prostate is a hormone-responsive organ where testicular androgens drive the proliferation and survival of prostatic cells, ensuring the development and functioning of this gland throughout life. Androgen deprivation therapy leads to apoptosis of prostatic cells and organ regression, and is a cornerstone of prostate cancer and benign prostatic hypertrophy treatment. For several decades, androgen deprivation has been used as an adjuvant to external beam radiotherapy, however, emerging data suggests that the low rates of epithelial proliferation in the castrated prostate imparts radio-resistance. As proliferating cells exhibit increased sensitivity to radiation, we hypothesized that short bursts of synchronized epithelial proliferation, which can be achieved by exogeneous testosterone supplementation prior to targeted high-dose radiation, would maximize sustained prostate ablation, while minimizing damage to surrounding tissues. To test this hypothesis, we designed a novel computed-tomography (CT)-guided stereotactic prostate radiation therapy (CT-SPRT) technique to deliver a single high-dose 25 Gy fraction of X-ray radiation. Sustained prostatic cell ablation was assessed post CT-SPRT by measuring prostate weight, epithelial cell number, and relative contributions of luminal and basal epithelial populations in control and testosterone-pretreated glands. CT-SPRT was safely delivered with no observed damage to surrounding rectal and bladder tissues. Importantly, castrated mice that received a pulse of testosterone to induce synchronous cell proliferation prior to CT-SPRT exhibited significant sustained gland ablation compared to control mice. These results provide new insights in stereotactic radiotherapy sensitivity to maximize prostatic cell ablation and improve our understanding of prostate gland regeneration that can potentially lead to improved non-invasive therapies for benign prostatic hypertrophy and prostate cancer.

Objective: To evaluate adherence to the American Urologic Association (AUA) best practice statement guidelines regarding antibiotic duration in the perioperative setting for endoscopic urologic surgery. We assessed concordance to these guidelines among adult urologists at a single academic institution and its correlation with postoperative positive urine cultures as it relates to the revised 2019 best practice statement.Methods: We performed a retrospective review of all adult endoscopic ambulatory urologic surgeries performed over an 18-month period by urologists at our institution. Patient demographics, pre- and postoperative urine cultures, operative details, stent or foley use, and antibiotic prescriptions were reviewed. Chi-squared and linear regression analyses were done.Results: Three hundred thirty patients were included for analysis. Sixty-two percent of patients were prescribed postoperative antibiotics, for an average of 4 days. Trimethoprim/Sulfamethoxazole and fluroquinolones were most often prescribed (43% and 38%, respectively). Intraoperative stent placement, positive urine culture within 30 days prior to surgery, and a positive urine culture within 1 year prior to surgery predicted antibiotic prescription. No significant differences were seen in rates of positive postoperative urine culture rates between cohorts that received antibiotics postoperatively vs those who did not.Conclusions: At our academic institution, we observed poor concordance with the AUA best practice statement for perioperative antibiotic prescription after ambulatory endoscopic urologic surgery. Rates of positive postoperative cultures were low and not associated with receipt or duration of antibiotic prescription at the time of surgery, supporting minimal use of antibiotics for most endoscopic cases.

Among US men, most new prostate cancer cases are clinically localized and do not require imaging as part of staging workup according to guidelines. Two leading specialty societies promote stewardship of health resources by encouraging guideline-concordant care, thereby limiting inappropriate and obsolete imaging. However, imaging to stage low-risk prostate cancer remains high, as almost half of men with localized prostate cancer undergo wasteful imaging following diagnosis. We employed a theory-based approach, based on current evidence and data on existing practice patterns revealing that providers are the drivers to imaging decisions, to design an intervention to improve guideline -concordant prostate cancer staging imaging across populations. We conceptualized preliminary results using the theoretical domains framework and the behavior change wheel, frameworks used concurrently to investigate physicians' behaviors and intervention design in various clinical settings. Through these 2 frameworks, we designed a theory-based, physician-focused intervention to efficiently encourage guideline-concordant prostate cancer imaging, prostate cancer imaging stewardship (PCIS). Prostate cancer imaging stewardship consists of interventions (clinical order check, academic detailing, and audit and feedback) implemented at the individual, facility, and system level to enact provider behavior change by enabling facilitators and appealing to physician motivation.

Background: Minimal literature informs the use of robotic partial nephrectomy (RPN) in patients with chronic kidney disease (CKD). Therefore, we evaluated the renal functional outcomes in CKD patients undergoing RPN. Methods: We reviewed a prospective database of patients undergoing RPN 2010 to 2015 and identified 182 patients who had preoperative and postoperative nuclear renal scintigraphy (at 2 and 12 months postop). Preoperative and 12-month postoperative eGFR (mL/min/1.73 m2, by MDRD) were calculated. CKD was defined as eGFR ≤60 mL/min/1.73 m2 (CKD stages III and IV). Changes in creatinine, eGFR, and split function on mercaptoacetyltriglycine (MAG)-3 scan were compared by baseline CKD status. Correlations between pre- and postoperative eGFR were calculated. Results: Of 182 patients, 30 (16.5%) had baseline CKD. Preoperative eGFR was 48.5 and 99.0 in CKD and non-CKD patients, respectively ( p  < 0.001). From preoperation to 12 months postoperation, eGFR decreased by 2.8 and 1.1 mL/min/1.73 m2, respectively ( p  = 0.6). On MAG-3 scan, the contribution of the surgical kidney to overall renal function decreased by 5.0% and 4.8% ( p  = 0.9) in the CKD and non-CKD cohorts, respectively. When comparing renal scans at 2 and 12 months postoperation, in both groups the surgical kidney significantly recovered (both p  < 0.001) and the patterns of kidney function recovery was similar in both groups (CKD +2.0%, non-CKD +1.4%, p  = 0.6). On long-term follow-up (>2 years), eGFR did not change significantly in either the CKD or non-CKD group (−2.8 vs −1.1 mL/min/1.73 m2, p  = 0.6). On pathology, tumors were more frequently malignant in CKD vs non-CKD patients (93.3% vs 73.2%, p  = 0.02) and of higher Fuhrman Grade (grade ≥3: 49.7% vs 28.1%, p  < 0.001). Conclusion: RPN is a reasonable treatment option in patients with CKD, as it did not lead to a greater decline in renal function contributed by the surgical kidney. The patterns of kidney function recovery after surgery are similar between patients with and without CKD. [ABSTRACT FROM AUTHOR]

• Active surveillance is a safe alternative to immediate treatment in select men. • Deferring treatment results in similar biochemical recurrence rates. • Race and ethnicity are not significantly associated with clinical reclassification. • Prostate specific antigen (PSA), PSA density, and prostate volume are potential predictors of reclassification. Active surveillance (AS) is the standard for very low- and low-risk prostate cancer. Although risk factors for pathologic reclassification while on AS have been identified, results are mixed for non-Hispanic Black (NHB) and Hispanic ethnicity. We aim to further explore how race and ethnicity may be affecting AS participation and outcomes in a primarily urban, diverse, and vulnerable population. Patients eligible for AS from 2005–2020 were reviewed. Demographics, race/ethnicity, prostate specific antigen (PSA), prostate volume, and pathologic characteristics were analyzed between patients enrolled in AS and those that underwent immediate therapy. Kaplan-Meier survival analysis was used to compare biochemical recurrence (BCR) rates. Cox proportional hazards models were used to develop prediction models for clinical reclassification. A total of 471 men were eligible for AS. Of those, 188 (39.9%) enrolled in AS while 283 (60.1%) underwent immediate radical therapy. No significant differences were found in racial/ethnic composition between the AS and immediate treatment groups. In our AS cohort, 79 (42.0%) experienced clinical reclassification and underwent deferred treatment. BCR rates were similar between treatment groups. Race/ethnicity were not found to be predictors of clinical reclassification, while metrics at diagnostic biopsy such as elevated PSA, higher PSA density, and lower prostate volume increased reclassification odds. In our diverse population, NHB race and Hispanic ethnicity were not significant predictors of adverse reclassification while on AS. Our findings support utilizing other metrics taken at initial biopsy to identify high-risk patients such as PSA, prostate volume, and PSA density. [ABSTRACT FROM AUTHOR]

Purpose: Increased adrenergic innervation is observed in prostate cancer (CaP) and is associated with aggressive disease. Emerging evidence suggests that beta-adrenergic blockade inhibits CaP progression. However, the association between type of beta-blocker use and risk of incident CaP on initial prostate biopsy has not been investigated in multiethnic populations.Materials and Methods: A retrospective study of racially/ethnically diverse men (64% African-American and Hispanic), who underwent initial prostate biopsy between 2006 and 2016 in a large healthcare system was performed. Oral use of beta-blocker type was assessed by reviewing active prescriptions within the 5-year period preceding initial biopsy. Patient demographics and clinical factors were collected.Results: Of 4,607 men who underwent initial prostate biopsy, 4,516 met criteria and 2,128 had a biopsy positive for CaP; 20% high-risk, 41% intermediate-risk, and 39% low or very-low risk (National Comprehensive Cancer Network classification). Overall, 15% of patients were taking a beta-blocker prior to initial biopsy, with Metoprolol, Atenolol, and Carvedilol accounting for the majority. Of beta-blocker types, Atenolol alone was associated with a 38% reduction in odds of incident CaP (P= 0.01), with a 40% and 54% reduction in risks of National Comprehensive Cancer Network intermediate and high-risk CaP (P = 0.03 and P = 0.03, respectively) compared to men not taking a beta-blocker. Furthermore, longer duration of Atenolol use (3-5 years) was associated with a 54% and 72% reduction in intermediate and high-risk disease, (P = 0.03 and P = 0.03, respectively).Conclusions: Among beta blocker types, long-term Atenolol use is associated with a significant reduction in incident CaP risk on initial prostate biopsy for clinically-significant intermediate and high-risk disease compared to men not taking a beta-blocker.
