To compare the carbon footprint and environmental impact of single-use and reusable flexible cystoscopes.We analysed the expected clinical lifecycle of single-use (Ambu aScope™ 4 Cysto) and reusable (Olympus CYF-V2) flexible cystoscopes, from manufacture to disposal. Performance data on cumulative procedures between repairs and before decommissioning were derived from a high-volume multispecialty practice. We estimated carbon expenditures per-case using published data on endoscope manufacturing, energy consumption during transportation and reprocessing, and solid waste disposal.A fleet of 16 reusable cystoscopes in service for up to 135 months averaged 207 cases between repairs and 3920 cases per lifecycle. Based on a manufacturing carbon footprint of 11.49 kg COIn this lifecycle analysis, the environmental impact of reusable flexible cystoscopes is markedly less than single-use cystoscopes. The primary contributor to the per-case carbon cost of reusable devices is energy consumption of reprocessing.

The presence of lower pole stones poses a unique challenge due to the anatomical considerations involved in their management and treatment. Considerable research has been performed to determine the optimal strategy when faced with this highly relevant clinical scenario. Standard options for management include observation, shock wave lithotripsy, retrograde intrarenal surgery, or percutaneous nephrolithotomy. Indeed, each approach confers a distinct set of risks and benefits, which must be placed into the context of patient preference and expected outcomes. The current state of practice reflects a combination of lessons learned from managing calculi not only in the lower pole, but also from other locations within the kidney as well.

BACKGROUND The American Urological Association makes recommendations for evaluation and testing for lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH) to help primary care providers and specialists identify LUTS/BPH and harmful related conditions including urinary retention and prostate or bladder cancer. Our understanding of provider adherence to these Guidelines is limited to single-site or nonrepresentative settings. METHODS We analyzed two insurance claims databases: the Optum® de-identified Clinformatics® Data Mart database for privately insured males aged 40-64 years (N ≈ 1,650,900 annually) and the Medicare 5% Sample for males aged ≥65 years (N ≈ 546,000 annually). We calculated the annual prevalence of LUTS/BPH and comorbid bladder cancer and bladder stones from 2004 to 2013. We additionally examined LUTS/BPH incidence and adherence to testing guidelines in a cohort of men newly diagnosed with LUTS/BPH in 2009. RESULTS While LUTS/BPH prevalence and incidence increased with increasing age, evaluation testing became less common. Urinalysis was the most common testing type but was performed in

Urinary incontinence is frequently underreported and underdiagnosed in the clinical setting. We analyzed 12 years of data from a large, nationally representative sample of women in the United States to assess the prevalence, severity, and daily impact of urinary incontinence and its subtypes at the population level.We analyzed data from 15,003 women aged ≥20 years who participated in the 2005-2016 National Health and Nutrition Examination Survey. We estimated the prevalence of urinary incontinence in the prior year, overall and by subtype (stress, urgency or mixed). Among women with urinary incontinence, we additionally assessed symptom severity using the validated 4-level Incontinence Severity Index, as well as impact on daily activities.The 2005-2016 prevalence of any urinary incontinence was 53%; 16% of women had mixed urinary incontinence, 26% had stress only and 10% had urgency only. While urgency urinary incontinence and mixed urinary incontinence were highest among women aged ≥60 years, stress urinary incontinence was highest among women aged 40-59 years. NonHispanic Black women had higher prevalence of urgency urinary incontinence and lower prevalence of stress urinary incontinence compared to other racial/ethnic groups. Of women with urinary incontinence, 30% reported moderate or severe symptoms, which were more common among older than younger women. In addition, 24% of women with urinary incontinence reported that the condition affected their daily activities.Our study demonstrates a high prevalence of urinary incontinence among a nationally representative population of women in the United States, with many reporting that urinary incontinence affected their daily activities. Age and racial/ethnic trends varied by urinary incontinence subtype.

To evaluate the total cost of outpatient flexible cystoscopy associated with reusable device purchase, maintenance, and reprocessing, and to assess potential cost benefits of single-use flexible cystoscopes. Cost data regarding the purchasing, maintaining, and reprocessing of reusable flexible cystoscopes were collected using a micro-costing approach at a high-volume outpatient urology clinic. We estimated the costs to facilities with a range of annual procedure volumes (1000–3000) performed with a fleet of cystoscopes ranging from 10 to 25. We also compared the total cost per double-J ureteral stent removal procedure performed using single-use flexible cystoscopes versus reusable devices. The cost associated with reusable flexible cystoscopes ranged from $105 to $224 per procedure depending on the annual procedure volume and cystoscopes available. As a practice became more efficient by increasing the ratio of procedures performed to cystoscopes in the fleet, the proportion of the total cost due to cystoscope reprocessing increased from 22 to 46%. For ureteral stent removal procedures, the total cost per procedure using reusable cystoscopes (range $165–$1469) was higher than that using single-use devices ($244–$420), unless the annual procedure volume was sufficiently high relative to the number of reusable cystoscopes in the fleet (≥ 350 for a practice with ten reusable cystoscopes, ≥ 700 for one with 20 devices). The cost of reprocessing reusable cystoscopes represents a large fraction of the total cost per procedure, especially for high-volume facilities. It may be economical to adopt single-use cystoscopes specifically for stent removal procedures, especially for lower-volume facilities.

Poor ergonomics in the operating room can have detrimental effects on a surgeon's physical, psychological and economic well-being. This problem is of particular importance to urologists who are trained in nearly all operative approaches (open, laparoscopic, robotic-assisted, microscopic and endoscopic surgery), each with their own ergonomic considerations. The vast majority of urologists have experienced work-related musculoskeletal pain or injury at some point in their career, which can result in leaves of absence, medical and/or surgical treatment, burnout, changes of specialty and even early retirement. Surgical ergonomics in urology has been understudied and underemphasized. In this Review, we characterize the burden of musculoskeletal injury in urologists and focus on various ergonomic considerations relevant to the urology surgeon. Although the strength of evidence remains limited in this space, we highlight several practical recommendations stratified by operative approach that can be incorporated into practice without interrupting workflow whilst minimizing injury to the surgeon. These recommendations might also serve as the foundation for ergonomics training curricula in residency and continuing medical education programmes. With improved awareness of ergonomic principles and the sequelae of injury related to urological surgery, urologists can be more mindful of their operating room environment and identify ways of reducing their own symptoms and risk of injury.

With the ubiquity of lower urinary tract symptoms due to benign prostatic hyperplasia (LUTS/BPH) in older men, costs related to this highly prevalent disease are likely significant but not well defined. With this study, we hoped to define costs related to LUTS/BPH care.We utilized the OptumThe Medicare cohort demonstrated a 23% increase in total costs over the study period with a 28% decrease in CDM costs. Decreases in inpatient hospital charges (45% for Medicare, 55% for CDM) were offset by increasing hospital-based outpatient fees (120% for Medicare, 87% for CDM). Overall, we estimated a total cost of at least $1.9 billion for treatment of men with LUTS/BPH for 2013. Per person expenditures increased with age within cohorts with an average per-person cost of $269 (CDM) and $248 (Medicare) in 2013.The distribution of healthcare expenditures for LUTS/BPH shifted across practice settings from 2004 to 2013, with increasing outpatient relative to inpatient expenditures. Total direct costs for LUTS/BPH in 2013 were at least $1.9 billion, not accounting for indirect costs or certain unmeasured populations.

OBJECTIVE To assess the quality and accuracy of online videos about the medical management of nephrolithiasis. MATERIALS AND METHODS To evaluate trends in online interest, we first examined the frequency of worldwide YouTube searches for 'kidney stones' from 2015 to 2020. We then queried YouTube with terms related to symptoms and treatment of kidney stones and analysed English-language videos with >5000 views. Quality was assessed using the validated DISCERN instrument. Evidence-based content analysis of video content and viewer comments was performed. RESULTS Online searches for videos about kidney stones doubled between 2015 and 2019 (P

Clinical guidelines have conflicting recommendations on the role of prostate artery embolization (PAE), a novel interventional radiology technique used to treat benign prostatic hyperplasia (BPH). In the absence of consensus among clinicians, patients may seek information online, where consumer-targeted content has proliferated in recent years. Our objective was to assess the content and quality of online information about prostate artery embolization (PAE). We evaluated patient interest and exposure to PAE by searching Google Trends for PAE and searching Google for BPH and treatment-related terms. To assess online content about PAE safety and efficacy, we queried Google for patient-oriented websites and YouTube for consumer videos, assessing quality using the validated DISCERN instrument and performing an evidence-based content analysis of how indications, risks, and benefits of PAE were presented. Worldwide searches for PAE peaked in 2019; PAE was mentioned in 15 (26%) of the 57 general BPH-related websites. From our PAE-specific searches, we identified 50 websites and 31 videos. Academic hospitals were the most common sponsor of both PAE-related websites (16, 32%) and videos (15, 48%). Among sources offering PAE to patients, only 15% of websites and 11% of videos explicitly did so as part of a clinical trial. The average DISCERN rating of quality of content was 3.0 out of 5 for websites and 2.0 out of 5 for videos (p

Validity of systematic reviews may be affected by non-publication of statistically non-significant or unfavorable clinical trial results. One function of clinical trial registries is to make these non-published studies available and thereby reduce potential publication bias. We aim to assess the use of clinical trial registries in published systematic reviews in urology. We identified all systematic reviews published in the five highest-impact general urology journals that publish original research between January 1 and December 31, 2017. Full-text analysis was performed to determine if protocols included searching clinical trial registries meeting WHO Registry Network criteria. Of a total of 204 search results, 92 were included in the analysis as systematic reviews. The majority searched the MEDLINE (91, 98%), EMBASE (69, 75%), and Cochrane (49, 53%) databases. Based on published methods, only 16 (17%) systematic reviews searched any clinical trial registries: 14 (15%) ClinicalTrials.gov, 6 (6%) WHO International Clinical Trials Registry Platform, and 2 (2%) ISRCTN registry. Rates of searching clinical trial registries were low regardless of the journal: 8 of 34 (24%) in European Urology; 2 of 10 (20%) in BJU International; 3 of 17 (18%) in Urology; 2 of 18 (11%) in The Journal of Urology; and 1 of 13 (8%) in World Journal of Urology. The majority of recently published systematic reviews in urology do not routinely search clinical trial registries. Inclusion of these registries can help identify unpublished trial data, which may improve the quality of systematic reviews by reducing publication bias.

Objective To examine the recent epidemiology of pediatric urinary stone disease (USD) in the United States. Methods We utilized the 2004-2016 Optum© Clinformatics® Data Mart database, a de-identified adjudicated administrative health claims database that includes 15-18 million individuals covered annually by commercial insurance in all 50 US states. The analysis included 12,739,125 children aged 0-18 years. We calculated annual rates of USD, ambulatory visits, and procedures, and the prevalence of prescription fills. Results The 2005-2016 USD rate was 59.5 cases per 100,000 person-years. The annual rate rose gradually from 2005 to a peak of 65.2 cases per 100,000 person-years in 2011. The USD rate increased with increasing age, and was highest among females compared to males, non-Hispanic Whites compared to other race/ethnic groups, and those residing in the South compared to other geographic regions. The overall 2005-2016 rate in the 120 days following a USD episode was 1.9 for ambulatory visits, 0.24 for surgical procedures, and 1.1 for imaging procedures. Ureteroscopy was the most common surgical procedure and CT scan was the most common imaging procedures, although ultrasound utilization increased over time. Medications were filled in 46.9% of cases, and use was lowest among males (43.1%), Asians (34.8%), and in the Northeast (34.3%). Opiate agonists were the most prevalent prescription (39.9%). Conclusion Our study provides one of the most comprehensive examinations of pediatric USD to date, demonstrating shifting rates and treatment patterns over time, as well as differences by age, gender, race/ethnicity, and geographic region.

The American Urological Association makes recommendations for evaluation and testing for lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH) to help primary care providers and specialists identify LUTS/BPH and harmful related conditions including urinary retention and prostate or bladder cancer. Our understanding of provider adherence to these Guidelines is limited to single-site or nonrepresentative settings.We analyzed two insurance claims databases: the OptumWhile LUTS/BPH prevalence and incidence increased with increasing age, evaluation testing became less common. Urinalysis was the most common testing type but was performed in60% of incident patients. Serum prostate-specific antigen (PSA) was the second most common test across age groups (range: 15-34%). Prevalence of comorbid bladder cancer (range: 0-4%), but not bladder stones (range: 1-2%), increased with increasing age.Although older men were at greater risk of LUTS/BPH than younger men, they were less likely to undergo testing at diagnosis. Recommended testing with urinalysis was poor despite higher prevalence of bladder cancer in older men and a standard recommendation for urinalysis since 1994. Providers should be more cognizant of AUA Guidelines when assessing LUTS/BPH patients.

Objective To examine US trends in neuromodulation for urinary incontinence (UI) treatment from 2004 to 2013. Methods This study utilized 2 data sources: the Optum© de-identified Clinformatics® Data Mart Database for privately insured adults aged 18-64 years with a UI diagnosis (N≈40,000 women and men annually) and the Medicare 5% Sample for beneficiaries aged ≥65 years with a UI diagnosis (N≈65,000 women and men annually). We created annual cross-sectional cohorts and assessed prevalence of UI-related neuromodulation procedures among men and women separately from 2004 to 2013. Analyses were conducted overall and stratified by age, race/ethnicity, and geographic region. Results Nearly all neuromodulation procedures occurred in outpatient settings. Sacral neuromodulation (SNM) procedures for UI in both women and men grew steadily from 2004 to 2013, with more procedures performed in women than men. Among women with UI, SNM prevalence grew from 0.1%-0.2% in 2004 to 0.5%-0.6% in 2013. Posterior tibial nerve stimulation (PTNS) experienced growth from 2011 to 2013. Chemodenervation of the bladder with onabotulinumtoxinA (BTX) combined with other injectable procedures (including urethral bulking) remained stable over time. Conclusions From 2004 to 2013, SNM procedures remained relatively uncommon but increased consistently. PTNS experienced growth starting in 2011 when PTNS-specific insurance claims became available. BTX trends remain unclear; future studies should assess it separately from other injectable procedures. Neuromodulation has a growing role in UI treatment, and ongoing trends will be important to examine.

Introduction: Accurate estimation of stone fragment size during ureteroscopic lithotripsy procedures facilitates operative efficiency and predicts the safety of fragment extraction or spontaneous passage. Using a novel stone measurement software application, this study assesses the feasibility of performing integrated real-time digital stone measurement during ureteroscopy. Methods: This workflow feasibility study was conducted in two phases. First, in the ex vivo simulation, mock stone fragments were placed in a renal collecting system training model. A basket extraction task was performed using a digital ureteroscope, with and without digital stone measurement. The time required to perform the tasks was recorded and compared. Second, in the in vivo workflow trial, adult patients undergoing ureteroscopic stone procedures were prospectively enrolled. Intraoperative measurements of stone fragments were performed to determine the time required to complete the measurements. Technical failures and perioperative complications were recorded. Results: In the ex vivo simulation, 20 mock stones mimicking varied fragmentation conditions were tested in the training model. The mean completion time of the basketing task without vs with digital stone measurement was 16.5 seconds (range 10.2-33.7) vs 38.9 seconds (range 27.2-60.0). Mean additional time required to measure stones was 22.3 seconds (range 8.4-42.7). In the in vivo workflow trial, nine patients undergoing ureteroscopy were enrolled. A median of five fragments (range 3-10) were measured in each patient. Mean completion time for each measurement was 10.1 seconds (range 8.2-12.8). Mean total time required to perform digital measurement per procedure was 50.8 seconds (range 25.9-99.0). No technical failures or clinical complications were observed. Conclusions: Integrating real-time digital stone measurement during ureteroscopy is safe and feasible. The findings support clinical trials of digital stone measurement to enhance intraoperative decision-making during ureteroscopy.
