Abstract
Introduction: Surgical training programs are pivotal in shaping skilled and compassionate surgeons, with mentors playing a crucial role in instilling clinical competence and essential attributes. This study aims to describe the characteristics of the program directors of Endourological Society-accredited fellowship programs. Methodology: The Endourological Society's website was used to identify program directors. The following data points were extracted: year of graduation from medical school, year of completing residency, if they had attended fellowship training or held additional degrees such as (PhD, MS, MBA, MSc, etc.), and number of publications on Scopus. Descriptive statistics were used to analyze the data. Results: A total of 84 fellowship programs and 115 program directors were identified. Geographically, 77.4% (n = 65) were in North America, 8.3% (n = 7) in Asia, 8.3% (n = 7) in the Middle East, 3.6% (n = 3) in Europe, and 2.4% (n = 2) in South America. Of the 115 program directors, 94.8% were male, and only 5.2% were female. Program directors graduated medical school with a median year of 1998 (1966-2015). Eighty percent attended fellowship programs, and 19.1% held additional degrees (PhD, MS, MBA, MSc, etc.). The median number of publications was 79 (4-1963), with a median citation of 1607 (1-43,565). The median H-index was 23 (range: 1-110). Conclusion: Most program directors of Endourological Society-accredited fellowship programs are fellowship-trained and a notable number held a second degree. However, a pronounced gender disparity is observed, with limited female representation among program directors. This assessment contributes valuable insights into the urology and endourology mentorship, emphasizing the need for broader diversity and inclusivity in leadership roles.

Abstract
Background: The journey of minimally invasive (MI) urology is one of quality improvement (QI) and patient safety. New techniques have been progressively studied for adoption and growth. As more advanced methods of data collection and analysis are developed, a review of the patterns and history of these principles in the development of MI urology can inform future urologic QI and patient safety initiatives. Objective: To perform a scoping review identifying patterns of QI and patient safety in MI urology. Methods: PubMed and the American Urological Association (AUA) journal search page were screened on December 2022 for publications using the search parameters "quality improvement" and "minimally invasive." Articles were screened according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews (PRISMA-ScR). Results: The initial literature search identified 471 articles from PubMed and 57 from the AUA journal search page. After screening, 528 articles were relevant to the topic and reviewed. Four hundred eighty-two articles were duplicates or did not meet inclusion criteria. Forty-six are included in this review. Conclusion: Urology has developed a pattern of assessing MI surgery vs the open counterpart. This includes analyzing the newest approach to understand complications, examining the factors contributing to complications, and lastly designing projects to mitigate future risk. This information, as well as advanced methods of data collection, has identified areas of improvement for new QI projects. The stage is set for a promising future with the adoption of advanced QI in daily urologic practice to improve patient safety and minimize errors.

Abstract
Purpose: Patients with recurring kidney stone events can expect significant morbidity and functional impairment. Few studies have evaluated the effect of bilateral kidney stones on disease progression and quality of life. We wanted to determine the association of bilateral stone disease on age of onset, and the impact on number of stone events and individual kidney stone disease-specific health-related quality of life (HRQOL) by analyzing the validated and prospectively collected Wisconsin Stone Quality of Life (WISQOL) database. Materials and Methods: We studied 2906 stone patients from 16 centers in North America after having completed the WISQOL questionnaire from 2014 to 2019. Kidney stone formers were assessed if kidney stones were bilateral or unilateral on imaging. Analysis with a chi-square test compared categorical variables. Bilateral kidney stone disease and its impact on HRQOL were evaluated through a multivariable linear regression model. Results: Of 2906 kidney stone formers, 1340 had unilateral kidney stones and 1566 had bilateral kidney stones. We observed more frequently that patients with bilateral stones had an increased number of depression/anxiety symptoms, renal tubular acidosis, and rheumatoid arthritis (all p < 0.05). Patients with bilateral stones had a younger mean (standard deviation [SD]) age of kidney stone disease onset (37.2 ± 15.8 vs 46.4 ± 15.9 years of age, p < 0.001). Bilateral kidney stone formers had a higher mean (SD) number of stone events (11.3 ± 21.8) than unilateral kidney stone formers (3.0 ± 5.1) (p < 0.001). Within our multivariable analysis, we found that HRQOL was negatively affected by the presence of bilateral stones for kidney stone patients (β = -11.2 [confidence interval: -19.5 to -3.0] points, p < 0.05). Conclusions: Bilateral kidney stone formers had a younger age of kidney stone disease onset and a higher number of stone events compared with unilateral kidney stone disease formers. The presence of bilateral kidney stone disease negatively impacted HRQOL.

Abstract
The Endourological Society, the premier urologic society encompassing endourology, robotics, and focal surgery, is composed of a diverse group of >1300 urologists. However, limited information has been collected about society members. Recognizing this need, a survey was initiated to capture data regarding current member practices, as well as help the Society shape the future direction of the organization. Presented herein is the inaugural Endourological Society census report as the beginning of a continued effort for global improvement in the field of endourology. Using a REDCap® database, an email survey was circulated to the membership of the Endourological Society from May through June 2021. Twenty questions were posed, categorizing member data in terms of epidemiology/demographics, practice patterns, member opinions, and future educational preferences. Responses were received from 534 members, representing 40.3% of membership. Data demonstrated that the average age, gender, race, and ethnicity of the typical Society member respondent is a 48-year-old Caucasian male working in the United States, with a mean of 25 years in practice. Retrograde endoscopy and percutaneous nephrolithotomy were identified as the most common practice skills, and 50% of members are involved in robotics. Importantly, the census confirmed that the World Congress of Endourology and Technology remains popular with Society members as a means of educational advancement. To sustain and advance the Society, information is required to understand the career interests and future educational desires of its members. This inaugural census provides crucial data regarding its membership and how the Society can achieve continued success and adjust its focus. Future census efforts will expand on the initial findings and stratify the data to elucidate changes in the needs of the Society as a whole. Circulating an annual census will allow for continued improvements in the field of endourology and, ultimately, better care for urologic patients.

Abstract
INTRODUCTION With a 5-year stone recurrence rate of 30-50%, kidney stone formers are subject to significant morbidity which negatively impacts their Health Related Quality of Life (HRQOL). We sought to determine the impact of age of kidney stone onset, duration of stone disease, and kidney stone event (surgery or stone passage) on patients' individual HRQOL by querying the validated and prospectively collected Wisconsin Stone Quality of Life (WISQOL) database. MATERIALS AND METHODS Cross-sectional data were obtained from a total of 2,438 kidney stone formers from 14 institutions in North America who completed the WISQOL questionnaire from 2014 to 2019. The 28-question survey has a 1-5 point scale for each item (total score range 0-140). Multivariable linear regression models assessed the impact of age of kidney stone onset, duration of stone disease and time since most recent surgery or stone passage on HRQOL. RESULTS Of 2,438 patients, older age at kidney stone onset and longer duration of disease were both independent predictors of better WISQOL (β=0.33 points/year; CI 0.17-0.49; p<0.001 and β=0.50 points/year; CI 0.32-0.68; p<0.001, respectively). Of 1,376 patients with surgery between 2010-2019, increased time since most recent surgery was an independent predictor of better WISQOL scores (β = 2.28 points/year; CI: 1.47-3.10; p=<0.001). Of 1,027 patients with spontaneous stone passage between 2010-2019, increased time since most recent stone passage was an independent predictor of better WISQOL scores (β = 1.59 points/year; CI: 0.59-2.59; p=<0.05). CONCLUSION Our study demonstrates that older age of onset, longer duration of disease, increase time from most recent surgery or stone passage were independent predictors of better HRQOL in kidney stone formers. Results of future studies that focus on optimizing stone related modifiable risk factors to decrease the amount of recurrent stone episodes and thus the need for recurrent surgeries will be essential.

Abstract
To evaluate the impact of chronic stone recurrence on an individual's quality of life using the validated Wisconsin Stone Quality of Life (WISQOL) questionnaire. We collected cross-sectional data on patients with kidney stones from 14 institutions in North America. A stone event was defined as renal colic, stone-related procedure or emergency department visit. The regression analyses using general linear models and pairwise comparison determined the impact of the number of stone events on quality of life. The median number of stone events among the 2205 patients who completed the questionnaire was 3 (IQR 1-6). The mean total score was 107.4 ± 28.7 (max 140 points). The number of lifetime stone events was an independent predictor of lower quality of life (p < 0.001), specifically, score declined significantly beyond five events. Compared with patients who experienced a single stone event, there was a 0.4, 2.5, and 6.9 point decline in the adjusted mean WISQOL score after 2-5, 6-10, or > 10 events, respectively. The cumulative number of lifetime stone events was associated with a lower quality of life when more than five stone events were occurred. These findings underscore the importance of efforts to determine the underlying metabolic etiology of urolithiasis in the recurrent stone former, and the institution of a regimen to place their stone disease in remission.

Abstract
OBJECTIVE To build the Wisconsin Stone Quality of Life Machine-Learning Algorithm (WISQOL-MLA) to predict urolithiasis patients' health-related quality of life (HRQoL) based on demographic, symptomatic and clinical data collected for the validation of the Wisconsin Stone Quality-of-Life (WISQOL) questionnaire, an HRQoL measurement tool designed specifically for patients with kidney stones. MATERIAL AND METHODS We used data from 3206 stone patients from 16 centres. We used gradient-boosting and deep-learning models to predict HRQoL scores. We also stratified HRQoL scores by quintile. The dataset was split using a standard 70%/10%/20% training/validation/testing ratio. Regression performance was evaluated using Pearson's correlation. Classification was evaluated with an area under the receiver-operating characteristic curve (AUROC). RESULTS Gradient boosting obtained a test correlation of 0.62. Deep learning obtained a correlation of 0.59. Multivariate regression achieved a correlation of 0.44. Quintile stratification of all patients in the WISQOL dataset obtained an average test AUROC of 0.70 for the five classes. The model performed best in identifying the lowest (0.79) and highest quintiles (0.83) of HRQoL. Feature importance analysis showed that the model weighs in clinically relevant factors to estimate HRQoL, such as symptomatic status, body mass index and age. CONCLUSIONS Harnessing the power of the WISQOL questionnaire, our initial results indicate that the WISQOL-MLA can adequately predict a stone patient's HRQoL from readily available clinical information. The algorithm adequately relies on relevant clinical factors to make its HRQoL predictions. Future improvements to the model are needed for direct clinical applications.

Abstract
Purpose: Metabolic syndrome (MetS) is a cluster of metabolic diseases that is linked to atherosclerotic cardiovascular disease. MetS has also been linked to increased nephrolithiasis. However, limited research has been conducted on MetS and its impact on stone-specific health-related quality of life (HRQOL). This study aims to examine the hypothesis that the presence of MetS is associated with decreased HRQOL. Materials and Methods: The Wisconsin Stone Quality of Life Questionnaire, a stone-specific HRQOL questionnaire, was used to survey 3051 patients with kidney stones. Medical history was collected from patients. These data were used to distinguish MetS patients from non-MetS patients. Among patients with current stones, a Wilcoxon rank sum test was used to compare HRQOL scores from MetS patients and non-MetS patients. HRQOL from patients with and without individual MetS components were also compared, and a multivariate analysis was conducted. Results: Statistical comparison between MetS patients (median score 102/140) and non-MetS patients (median score 106/140) demonstrated a lower stone-specific HRQOL in patients with MetS (p = 0.049). Among individual MetS components, patients with diabetes mellitus (DM) or body mass index (BMI) >30 had significantly lower HRQOL than patients without DM or BMI <30 (p = 0.028 and p < 0.001, respectively). The multivariate analysis supported this trend as MetS remained a significant predictor of decreased HRQOL (p = 0.002) after controlling for other variables assessed. Conclusions: This study indicates an association between MetS and a lower stone-specific QOL. This has important implications for stone prevention strategies in patients with MetS. Clinical Trial Registration number: H14-01143.

Abstract
PURPOSE To investigate the accuracy of rapid kV-switching single-source dual-energy computed tomography (rsDECT) for prediction of classes of non-uric-acid stones. MATERIALS AND METHODS Non-uric-acid renal stones retrieved via percutaneous nephrolithotomy were prospectively collected between January 2017 and February 2018 in a single institution. Only stones ≥ 5 mm and with pure composition (i.e., ≥ 80% composed of one component) were included. Stone composition was determined using Fourier Transform Infrared Spectroscopy. The stones were scanned in 32-cm-wide anthropomorphic whole-body phantom using rsDECT. The effective atomic number (Zeff), the attenuation at 40 keV (HU40), 70 keV (HU70), and 140 keV (HU140) virtual monochromatic sets of images as well as the ratios between the attenuations were calculated. Values of stone classes were compared using ANOVA and Mann-Whitney U test. Receiver operating curves and area under curve (AUC) were calculated. A p value < 0.05 was considered statistically significant. RESULTS The final study sample included 31 stones from 31 patients consisting of 25 (81%) calcium-based, 4 (13%) cystine, and 2 (6%) struvite pure stones. The mean size of the stones was 9.9 ± 2.4 mm. The mean Zeff of the stones was 12.01 ± 0.54 for calcium-based, 11.10 ± 0.68 for struvite, and 10.23 ± 0.75 for cystine stones (p < 0.001). Zeff had the best efficacy to separate different classes of stones. The calculated AUC was 0.947 for Zeff; 0.833 for HU40; 0.880 for HU70; and 0.893 for HU140. CONCLUSION Zeff derived from rsDECT has superior performance to HU and attenuation ratios for separation of different classes of non-uric-acid stones.

Abstract
Percutaneous Nephrolithotomy is the standard surgical procedure used to remove large kidney stones. PCNL procedures have a steep learning curve; a physician needs to complete between 36 and 60 procedures, to achieve clinical proficiency. Marion Surgical K181 is a virtual reality surgical simulator, which emulates the PCNL procedures without compromising the well-being of patients. The simulator uses a VR headset to place a user in a realistic and immersive operating theater, and haptic force-feedback robots to render physical interactions between surgical tools and the virtual patient. The simulator has two modules for two different aspects of PCNL kidney stone removal procedure: kidney access module where the user must insert a needle into the kidney of the patient, and a kidney stone removal module where the user removes the individual stones from the organ. In this paper, we present user trials to validate the face and construct validity of the simulator. The results, based on the data gathered from 4 groups of users independently, indicate that Marion's surgical simulator is a useful tool for teaching and practicing PCNL procedures. The kidney stone removal module of the simulator has proven construct validity by identifying the skill level of different users based on their tool path. We plan to continue evaluating the simulator with a larger sample of users to reinforce our findings.

Abstract
INTRODUCTION Urolithiasis causes a significant impact on health-related quality of life (HRQOL). Patients with kidney stones have high levels of stress and anxiety. Symptom resolution often requires treatment. Travel distance is a barrier to care but little is known about its effects on HRQOL. We hypothesize that increased distance to treatment site is associated with decreased HRQOL. METHODS Patients with a history of stones were enrolled at 11 tertiary centers as part of the QOL Stone Consortium of North America. HRQOL data were obtained using the Wisconsin Stone Quality of Life questionnaire (WISQOL). We calculated distance between patient and treatment site using national ZIP codes. We used linear models to evaluate the effect of distance on HRQOL, while also considering demographics data, stones/symptom status, and distance. RESULTS Of the 1676 enrolled patients, 52% were male, 86% non-Latino White, and the mean age was 53 years. Mean distance to treatment site was 63.3 km (range 0-3774), with 74% reporting current stones and 45% current symptoms. WISQOL score and distance were negatively correlated for patients reporting current stones and symptoms (p=0.0010). Linear modelling revealed decreased WISQOL scores for patients with symptoms as distance increased from treatment site (p=0.0001), with a 4.7-point decrease for every 100 km traveled. CONCLUSIONS Stone disease imposes significant burden on patients' HRQOL due to a variety of factors. Patients with active stone symptoms report worse HRQOL with increased distance to their treatment site. Possible etiologies include travel burden, increased disease burden, decreased healthcare use, and delays in care.

Trends in renal calculus composition and 24-hour urine analyses in patients with neurologically derived musculoskeletal deficiencies. Int Braz J Urol 2019; 45:572-580. [PMID: 30676304 PMCID: PMC6786099 DOI: 10.1590/s1677-5538.ibju.2018.0531] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2018] [Accepted: 10/05/2018] [Indexed: 11/28/2022] Open
Abstract
Purpose: To better characterize metabolic stone risk in patients with neurologically derived musculoskeletal deficiencies (NDMD) by determining how patient characteristics relate to renal calculus composition and 24-hour urine parameters. Materials and Methods: We performed a retrospective cohort study of adult patients with neurologically derived musculoskeletal deficiencies presenting to our multidisciplinary Kidney Stone Clinic. Patients with a diagnosis of NDMD, at least one 24-hour urine collection, and one chemical stone analysis were included in the analysis. Calculi were classified as primarily metabolic or elevated pH. We assessed in clinical factors, demographics, and urine metabolites for differences between patients who formed primarily metabolic or elevated pH stones. Results: Over a 16-year period, 100 patients with NDMD and nephrolithiasis were identified and 41 met inclusion criteria. Thirty percent (12 / 41) of patients had purely metabolic calculi. Patients with metabolic calculi were significantly more likely to be obese (median body mass index 30.3kg / m2 versus 25.9kg / m2), void spontaneously (75% vs. 6.9%), and have low urine volumes (100% vs. 69%). Patients who formed elevated pH stones were more likely to have positive preoperative urine cultures with urease splitting organisms (58.6% vs. 16.7%) and be hyperoxaluric and hypocitraturic on 24-hour urine analysis (37mg / day and 265mg / day versus 29mg / day and 523mg / day). Conclusions: Among patients with NDMD, metabolic factors may play a more significant role in renal calculus formation than previously believed. There is still a high incidence of carbonate apatite calculi, which could be attributed to bacteriuria. However, obesity, low urine volumes, hypocitraturia, and hyperoxaluria suggest an underrecognized metabolic contribution to stone formation in this population.

Abstract
PURPOSE To our knowledge it is unknown whether the benefits of medical management of urolithiasis outweigh the potential side effects of the medications used, including potassium citrate and thiazide diuretics. Therefore, we evaluated the relationship between potassium citrate or thiazides and overall stone related health related quality of life. MATERIALS AND METHODS Cross-sectional data were obtained on stone forming enrollees in the North American Stone Quality of Life Consortium. We used the WISQOL (Wisconsin Stone Quality of Life) questionnaire to compare health related quality of life between patients treated and not treated with potassium citrate or thiazide type diuretics. Additionally, the likelihood of gastrointestinal complaints was compared between those prescribed and not prescribed potassium citrate. The likelihood of fatigue and sexual complaints was also compared in those prescribed and not prescribed thiazides. RESULTS Of the 1,511 subjects, including 787 males and 724 females, 279 were on potassium citrate and 238 were on thiazides at study enrollment. Patients prescribed potassium citrate had higher health related quality of life in each domain vs those not prescribed potassium citrate (p <0.001). Patients prescribed thiazides had higher health related quality of life in each domain compared to those not prescribed thiazide (all p <0.01). Those prescribed potassium citrate were less likely than those not prescribed potassium citrate to report nausea, stomach upset or cramps (OR 0.57, p <0.001). Patients prescribed thiazides were less likely than those not prescribed thiazides to report fatigue (OR 0.63, p = 0.004) or reduced sexual interest and/or activity (OR 0.64, p = 0.005). CONCLUSIONS Among stone formers the use of potassium citrate and thiazides was associated with better health related quality of life across all WISQOL domains without an increased likelihood of gastrointestinal complaints and fatigue or sexual complaints, respectively. These findings may be useful when counseling patients regarding the initiation of potassium citrate or thiazides for medical management of nephrolithiasis.

Abstract
INTRODUCTION The FDA (U.S. Food and Drug Administration) recently revised the boxed warning on fluoroquinolones to address serious safety concerns. This action was prompted by a growing number of reports involving patients with a constellation of symptoms now called fluoroquinolone associated disability. METHODS Internet and literature searches were performed to identify previous reports of quinolone induced multisystem toxicity syndromes. The 3 terms fluoroquinolone toxicity, quinolone toxicity syndrome and fluoroquinolone associated disability were used to query PubMed® and Google's search engine for available information. RESULTS Four primary sources emerged, including a recent FDA review, 2 case series and robust social media platforms. The FDA identified 1,122 fluoroquinolone disability reports from November 1, 1997 to May 30, 2015. A total of 178 cases qualified as fluoroquinolone associated disability after applying inclusion and exclusion criteria. Some estimate that there are as many as 45,000 cases of fluoroquinolone toxicity syndrome in the United States. All sources agree the affected population is generally young (mean age 40s to 50s), previously healthy and predominantly female. The FDA analysis revealed that average symptom duration was 14 months and longest duration was 9 years at the time of the review. CONCLUSIONS Fluoroquinolone toxicity syndromes do not affect the majority of exposed patients but are likely underappreciated. As providers seeking to heal and avoid harm to our patients, diligent prescribing practices are paramount, as are early recognition and discontinuation of the antibiotic.

Abstract
INTRODUCTION Regulations and guidelines are essential components of maintaining safety in multiple industries. In health care these processes exist to help distinguish weaknesses in patient care and identify adverse events. We review the processes that have been established in health care to promote the culture of patient safety. METHODS Sources were acquired through the NCBI (National Center for Biotechnology Information) database using the keywords "safety," "World Health Organization" and "Joint Commission on Accreditation of Healthcare Organizations." Other sources were obtained through research into specific safety processing topics of industrial and nonindustrial institutions. RESULTS The organizational properties of patient care expand beyond the number of incidents an institution experiences and include standardized safety values for specific patient care procedures. Tools such as SBAR (Situation, Background, Assessment, Recommendation), Reason's Swiss cheese model and the general guidelines established by the WHO have been used to detect and reduce the likelihood of errors in patient practice. These tools also demonstrate the importance of adopting regulated checklists and protocols that are essential at every stage of patient care. CONCLUSIONS While various systems have been implemented throughout the health care industry to overcome processing weaknesses, a continued display of effectiveness and improvement of current subspecialty specific guidelines are necessary for the assurance of safety in contemporary patient care.

Abstract
INTRODUCTION The focus of quality metrics is to ensure that physicians provide and practice within a standard of care, and to maximize patient benefit and safety. Several quality reporting programs in urology such as SCIP (Surgical Care Improvement Project, PQRS (Physician Quality Reporting System) and OPPE (Ongoing Professional Practice Evaluation)/FPPE (Focused Professional Practice Evaluation) have been used to review and monitor standards of care and improve medical care quality. Urological databases are emerging with the main focus of reviewing and assessing health care delivery quality and patient outcomes. Such data will likely influence future quality improvement measures and standards. Awareness and understanding of these programs and measurements are vital to continued successful urological practice. METHODS AUA (American Urological Association) and CMS (Centers for Medicare and Medicaid Services) documents were used. We reviewed program specific requirements, including minimal required data, timeline requirements, and specific incentives and penalties. RESULTS Quality measures and programs in urology aim to monitor, standardize and improve medical care delivery in the United States. Since the implementation of electronic health records, the ability to review individual and group medical practices has become available and reviewable by outside agencies. Universal practice standards and government monitoring of individual and group achievement of those expectations are the current direction of health care. This is exemplified by the United States DHHS (Department of Health and Human Services) announcement of transitioning Medicare to a value based reimbursement model and the 9 HCTTF (Health Care Transformation Task Force) principles for accountable care organization footprint expansion. CONCLUSIONS The quality era has arrived. Its continued impact on health care delivery will be noted as public reporting and payment modifications based on quality indicators and performance metrics.

Abstract
INTRODUCTION Catheter associated urinary tract infections are widely recognized as the most common health care associated infection in the acute care hospital setting. METHODS Experts have reviewed the literature on catheter associated urinary tract infections in urological patients. Where the literature was lacking, expert opinion was used to build recommendations which may be useful to the urological community. RESULTS In this white paper we address limitations surrounding how and when current definitions can be used to detect a catheter associated urinary tract infection in a urological patient, and propose alternative methods for diagnosing catheter associated urinary tract infection in specific populations, including geriatric, neurogenic bladder and lower urinary tract reconstruction. Techniques to avoid catheter associated urinary tract infections through proper urethral catheterization and alternatives to indwelling catheters for urological patients are also discussed. CONCLUSIONS Patients with urological disorders have specific concerns relating to catheter associated urinary tract infections. A review of the available literature as well as common clinical practice provides directives for the treatment of these patients in a specific and distinctive fashion to reduce the risk of infection. By understanding the needs and technical modifications necessary in these patients, hospital systems and practitioners can limit patient exposure to catheter associated urinary tract infections.

Abstract
BACKGROUND AND PURPOSE Ureteral injuries such as avulsion are directly related to mechanical damage of the ureter. Understanding the tensile strength of this tissue may assist in prevention of iatrogenic injuries. Few published studies have looked at the mechanical properties of the animal ureter and, of those, none has determined the tensile strength of the human ureter. Therefore, the purpose of this work was to determine the tensile strength of the human ureter. METHODS We harvested 11 human proximal ureters from patients who were undergoing nephrectomy for either kidney tumors or nonfunctioning kidney. The specimens were then cut into multiple circumferentially and longitudinally oriented tissue strips for tensile testing. Strips were uniaxially stretched to failure in a tensile testing machine. The corresponding force and displacement were recorded. Finally, stress at failure was noted as the tensile strength of the sample. Circumferential tensile strength was also compared in the proximal and distal regions of the specimens. RESULTS The tensile strength of the ureter in circumferential and longitudinal orientations was found to be 457.52±33.74 Ncm(-2) and 902.43±122.08 Ncm(-2), respectively (P<0.001). The circumferential strength in the proximal portion of the ureter was 409.89±35.13 Ncm(-2) in comparison with 502.89±55.85 Ncm(-2) in the distal portion (P=0.08). CONCLUSIONS The circumferential tensile strength of the ureter was found to be significantly lower than the longitudinal strength. Circumferential tensile strength was also lower with more proximal parts of the ureter. This information may be important for the design of "intelligent" devices and simulators to prevent complications.

Abstract
INTRODUCTION We performed a more detailed, updated analysis of social media use by AUA members. Specifically we sought to characterize the frequency of and reason for using different social media platforms as well as barriers to social media use. METHODS From November to December 2013 we sent a 21-item survey on social media use to 16,376 AUA members with a valid email address. A total of 1,114 members (6.8%) completed the survey. Responses were tallied and statistical analysis was performed to evaluate use patterns based on demographic characteristics. RESULTS Overall 71% of AUA members who responded to the survey currently had a social media account. The most popular social media platform was Facebook® (89% of respondents), followed by LinkedIn® (59%), YouTube™ (54%), Twitter® (48%) and Google+™ (35%). All platforms except LinkedIn were used primarily for personal reasons. Fewer than a third of respondents had viewed an AUA social media site and 35% of physician respondents participated in a physician-only social media community. Among respondents who did not use social media the most common reasons were no perception of added value and privacy concerns. CONCLUSIONS Although most AUA respondents are involved in social media, they primarily use social media for personal reasons. There remains significant potential for growth and education on the usefulness of social media for urologists in the professional setting.

Abstract
PURPOSE The urology match is highly competitive but there is a paucity of published data regarding the costs and barriers that applicants face. We gathered data on contributors to cost in the 2014 urology residency match. MATERIALS AND METHODS A survey was sent to all applicants offered an interview at each of 18 participating institutions. Information on demographics, interview related costs, access to financial aid, frequency of away rotations and second look invitations was collected. RESULTS A total of 173 respondents spent a median of $7,000 on the urology match. Applicants attended a mean of 14 interviews with an average per interview cost of $500. Overall 95% of respondents did at least 1 away rotation and 79% reported being asked to return for a second look interview at least once. Of the respondents 66% did not receive any financial aid for interviews and only 28% believed their financial aid departments provided adequate financial planning. Of those surveyed 20% indicated that their financial situation limited the number of interviews they attended. CONCLUSIONS We estimate that $3,122,000 was spent by applicants on the 2014 urology match. One in 5 applicants reported limiting the number of interviews they attended due to financial concerns. Adequate financial planning resources were not widely available. Nearly all applicants went on an away rotation and encouragement to return for second look interviews was common. These factors may contribute to financial and regional bias in the match process, and are potential targets for reform.

Abstract
Percutaneous nephrolithotomy (PCNL) is the standard treatment for patients with large stone burdens, but can be associated with significant complications. Flexible ureteroscopy is an alternative approach that is less invasive, but often requires multiple procedures. Typically, many factors play a role in the decision to perform PCNL or ureteroscopy. The challenge is that it is difficult to predict which stone burdens will be able to be cleared ureteroscopically. We describe our approach using initial prone ureteroscopy with the transition to standard prone PCNL if required.

Abstract
BACKGROUND AND PURPOSE Magnesium (Mg(2+)) has been shown to be a kidney stone inhibitor; however, the exact mechanism of its effect is unknown. Using theoretical models, the interactions of calcium and oxalate were examined in the presence of Mg(2+). METHODS Molecular dynamics simulations were performed with NAMD and CHARMM27 force field. The interaction between calcium (Ca(2+)) and oxalate (Ox(2-)) ions was examined with and without magnesium. Concentrations of calcium and oxalate were 0.1 M and 0.03 M, respectively, and placed in a cubic box of length ~115 Angstrom. Na(+) and Cl(-) ions were inserted to meet system electroneutrality. Mg(2+) was then placed into the box at physiologic concentrations and the interaction between calcium and oxalate was observed. In addition, the effect of citrate and pH were examined in regard to the effect of Mg(2+) inhibition. Each system was allowed to run until a stable crystalline structure was formed. RESULTS The presence of Mg(2+) reduces the average size of the calcium oxalate and calcium phosphate aggregates. This effect is found to be Mg(2+) concentration-dependent. It is also found that Mg(2+) inhibition is synergistic with citrate and continues to be effective at acidic pH levels. CONCLUSION The presence of magnesium ions tends to destabilize calcium oxalate ion pairs and reduce the size of their aggregates. Mg(2+) inhibitory effect is synergistic with citrate and remains effective in acidic environments. Further studies are needed to see if this can be applied to in vivo models as well as extending this to other stone inhibitors and promoters.

Abstract
OBJECTIVE To assess the efficacy of dietary management for the treatment of idiopathic hyperoxaluria in a large tertiary care center and examine the influence of patient factors, compliance, and follow-up on oxalate reduction, which has not been previously investigated. METHODS Retrospectively, 149 patients with kidney stones with idiopathic hyperoxaluria who received dietary management at our stone clinic were evaluated. Changes in urinary parameters on 24-hour urine collections were calculated for all patients and those with abnormal values in the overall short-term (30-240 days) and long-term (>240 days) time periods. Changes in urinary oxalate were evaluated with respect to patient characteristics and compliance measures. RESULTS Urine oxalate and supersaturation of calcium oxalate were significantly (P < .001) reduced by 8.9 ± 19.2 mg/d and 1.7 ± 4.3, respectively. A total of 48.3% of the patients reduced their urinary oxalate to normal. Urine oxalate reductions were similar in the short-term and long-term periods. Women lowered urine oxalate nearly twice as much as men (12.7 ± 2.0 mg/d vs 6.7 ± 2.2 mg/d, P = .022) and body mass index (BMI) negatively correlated with oxalate reduction (Pearson's r = -0.213). Reported noncompliance and keeping follow-up appointments did not affect oxalate, however, there was a significant correlation between increasing urine volume and reducing oxalate (Pearson's r = -0.21). CONCLUSION This study confirms that meaningful reductions of urine oxalate and supersaturation of calcium oxalate can be achieved with dietary management of hyperoxaluria on a larger clinical scale. Furthermore, we identified that women and patients with low BMIs had greater urine oxalate reductions and urine volume may also be used by clinicians as a measure of dietary compliance.
