  11. Financial Conflicts of Interest Among Authors of Urology Clinical Practice Guidelines.

    PubMed

    Carlisle, Austin; Bowers, Aaron; Wayant, Cole; Meyer, Chase; Vassar, Matt

    2018-05-07

    Recent studies have highlighted the presence of disclosed and undisclosed financial conflicts of interest among authors of clinical practice guidelines. We sought to determine to what extent urology guideline authors receive and report industry payments in accordance with the Physician Payment Sunshine Act. We selected the 13 urology guidelines that were published by the American Urological Association (AUA) after disclosure was mandated by the Physician Payment Sunshine Act. Payments received by guideline authors were searched independently by two investigators using the Open Payments database. Our primary outcome measure was the number of authors receiving payments from industry, stratified by amount thresholds. Our secondary outcome measure was the number of authors with accurate conflict of interest disclosure statements. We identified a total of 54 author disclosures. Thirty-two authors (59.3%) received at least one payment from industry. Twenty (37.0%) received >$10 000 and six (11.1%) received >$50 000. Median total payments were $578 (interquartile range $0-19 228). Twenty (37.0%) disclosure statements were inaccurate. Via Dollars for Docs, we identified $74 195.13 paid for drugs and devices directly related to guideline recommendations. We were limited in our ability to determine when authors began working on guideline panels, as this information was not provided, and by the lack of specificity in Dollars for Docs. Many of the AUA guideline authors received payments from industry, some in excess of $50 000. A significant portion of disclosure statements were inaccurate, indicating a need for more stringent enforcement of the AUA disclosure policy. Pharmaceutical company payments to doctors have been shown to influence how doctors treat patients. If these doctors are charged with making clinical recommendations to other doctors, in the form of clinical practice guidelines, the issue of industry payments becomes more severe. We found that many urologists on guideline panels receive money from industry and that a significant portion did not disclose all payments received. Copyright © 2018 European Association of Urology.

    2006-01-01

    Urology has increasingly become a technology‐driven specialty. The advent of robotic surgical systems in the past 10 years has led to urologists becoming the world leaders in the use of such technology. In this paper, we review the history and current status of robotic technology in urology. From the earliest uses of robots for transurethral resection of the prostate, to robotic devices for manipulating laparoscopes and to the current crop of master–slave devices for robotic‐assisted laparoscopic surgery, the evolution of robotics in the urology operating theatre is presented. Future possibilities, including the prospects for nanotechnology in urology, are awaited. PMID:17099094

    Abstract Urologic and kidney problems are common in women across their life span and affect their daily life, including physical activity, sexual relations, social life, and future health. Urological health in women is still understudied and the underlying mechanisms of female urological dysfunctions are not fully understood. The Society for Women's Health Research (SWHR®) recognized the need to have a roundtable discussion where researchers and clinicians would define the current state of knowledge, gaps, and recommendations for future research directions to transform women's urological health. This report summarizes the discussions, which focused on epidemiology, clinical presentation, basic science, prevention strategies, and efficacy of current therapies. Experts around the table agreed on a set of research, education, and policy recommendations that have the potential to dramatically increase awareness and improve women's urological health at all stages of life.

    Live surgery is an important part of surgical education, with an increase in the number of live surgery events (LSEs) at meetings despite controversy about their real educational value, risks to patient safety, and conflicts of interest. To provide a European Association of Urology (EAU) policy on LSEs to regulate their organisation during urologic meetings. The project was carried out in phases: a systematic literature review generating key questions, surveys sent to Live Surgery Panel members, and Internet- and panel-based consensus finding using the Delphi process to agree on and formulate a policy. The EAU will endorse LSEs, provided that the EAU Code of Conduct for live surgery and all organisational requirements are followed. Outcome data must be submitted to an EAU Web-based registry and complications reported using the revised Martin criteria. Regular audits will take place to evaluate compliance as well as the educational role of live surgery. This policy represents the consensus view of an expert panel established to advise the EAU. The EAU recognises the educational role of live surgery and endorses live case demonstration at urologic meetings that are conducted within a clearly defined regulatory framework. The overriding principle is that patient safety must take priority over all other considerations in the conduct of live surgery. Controversy exists regarding the true educational value of live surgical demonstrations on patients at surgical meetings. An EAU committee of experts developed a policy on how best to conduct live surgery at urologic meetings. The key principle is to ensure safety for every patient, including a code of conduct and checklist for live surgery, specific rules for how the surgery is organised and performed, and how each patient's results are reported to the EAU.

    URobotics (Urology Robotics) is a program of the Urology Department at the Johns Hopkins Medical Institutions dedicated to the development of new technology for urologic surgery (http://urology.jhu.edu/urobotics). The program is unique in that it is the only academic engineering program exclusively applied to urology. The program combines efforts and expertise from the medical and engineering fields through a close partnership of clinical and technical personnel. Since its creation in 1996, the URobotics lab has created several devices, instruments, and robotic systems, several of which have been successfully used in the operating room. This article reviews the technology developed in our laboratory and its surgical applications, and highlights our future directions. PMID:11954067

    Healthcare is expensive for a large proportion of the population in spite of high per capita income and good health insurance penetration. In an effort to reduce cost of the procedure, reprocessing of devices was started in the late 1970s. Reprocessing practice includes various measures such as proper cleaning, disinfection, and sterilization procedures. As reprocessing is aimed at reducing cost, there is a potential risk of compromising patient safety due to cross contamination after inadequate sterilization. There is also risk of performance alteration of urological reprocessed devices during sterilization/disinfection processing. Therefore, there is a need for formulating proper guidelines to decide methods of reprocessing for various urological equipment. There is also need to discuss the problematic areas that urologists face and to find their solutions. A PubMed search was made in September 2016, using key words “reprocessing of medical devices,” “Single Use Devices,” “methods of reprocessing of devices in clinical practice,” “use of formalin chamber,” “urological disposable sterilization,” etc., After excluding duplicates, all English articles were reviewed by title and abstract. Full texts of selected articles were obtained, and these articles were cross-referenced to find any other related articles. All the articles were reviewed. A product can be reused if it can be economically reprocessed with validated protocols with preservation of its function. There is no reason to discard it after one use. This practice is useful for controlling economics of a urological case and to reduce the financial burden. Current Food and Drug Administration guidelines are stringent. The contamination described to test the sterilization process in the suggested guidelines actually does never exist in clinical practice. Therefore, new guidelines considering the clinical practice scenario are desirable. PMID:28479760

    Despite being an ancient surgical specialty, modern urology is technology driven and has been quick to take up new minimally invasive surgical challenges. It is therefore no surprise that much of the early work in the development of surgical robotics was pioneered by urologists. We look at the relatively short history of robotic urology, from the origins of robotics and robotic surgery itself to the rapidly expanding experience with the master-slave devices. This article credits the vision of John Wickham who sowed the seeds of robotic surgery in urology.

    Recent developments in virtual, augmented, and mixed reality have introduced a considerable number of new devices into the consumer market. This momentum is also affecting the medical and health care sector. Although many of the theoretical and practical foundations of virtual reality (VR) were already researched and experienced in the 1980s, the vastly improved features of displays, sensors, interactivity, and computing power currently available in devices offer a new field of applications to the medical sector and also to urology in particular. The purpose of this review article is to review the extent to which VR technology has already influenced certain aspects of medicine, the applications that are currently in use in urology, and the future development trends that could be expected.

    A rapid expansion in the medical applications of three-dimensional (3D)-printing technology has been seen in recent years. This technology is capable of manufacturing low-cost and customisable surgical devices, 3D models for use in preoperative planning and surgical education, and fabricated biomaterials. While several studies have suggested 3D printers may be a useful and cost-effective tool in urological practice, few studies are available that clearly demonstrate the clinical benefit of 3D-printed materials. Nevertheless, 3D-printing technology continues to advance rapidly and promises to play an increasingly larger role in the field of urology. Herein, we review the current urological applications of 3D printing and discuss the potential impact of 3D-printing technology on the future of urological practice. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

    Aggarwal, Gaurav; Adhikary, Samiran D

    2017-06-01

    Simulation devices have grasped the attention of almost all industries worldwide and the medical field has not been exempt. With technological advancement, it becomes important to assess whether medical simulators are the way forward as an adjunct or as a replacement to traditional training approaches by assessing their safety, efficacy and cost-effectiveness, and whether they should be made mandatory in the curriculum of urology training. The present review aims to clarify some of these issues, as well as assess their role in urological training and present both the pros and cons of this simulation-based training.

    To analyse the activity, content, contributors, and influencers of the Twitter discussion on urologic oncology. We performed a comprehensive quantitative and qualitative Twitter analysis for the hashtags #prostatecancer, #bladdercancer, #kidneycancer, and #testicularcancer. Symplur was used to analyse activity over different time periods and the top influencers of the Twitter discussion. Tweet Archivist and Twitonomy analysis tools were used to assess characteristics of content and contributors. Twitter discussion on urologic oncology in 2014 contained 100,987 tweets created by 39,326 participants. Mean monthly tweet activity was 6,603±2,183 for #prostatecancer, 866±923 for #testicularcancer, 457±477 for #bladdercancer and 401±504 for #kidneycancer. Twitter activity increased by 41% in 2013 and by 122% in 2014. The content analysis detected awareness, cancer, and risk as frequently mentioned words in urologic oncology tweets. Prevalently used related hashtags were the general hashtag #cancer, awareness hashtags, and the respective cancer/urology tag ontology hashtags. Contributors originated from 41 countries on 6 continents and had a mean of 5,864±4,747 followers. They tweeted from platforms on exclusively mobile devices (39%) more frequently than from desktop devices (29%). Health care organizations accounted for 58% of the top influencers in all cancers. The largest proportion of physicians were among the #prostatecancer and #kidneycancer (each 9%) influencers and individual contributors were most frequent in the discussion on #kidneycancer (57%) and #testicularcancer (50%). There is a significant and growing activity in the Twitter discussion on urologic oncology, particularly on #prostatecancer. The Twitter discussion is global, social, and mobile, and merits attention of stakeholders in health care as a promising communication tool. Copyright © 2016 Elsevier Inc. All rights reserved.

    Goldberg, Jay

    2012-01-01

    In 1990, I was the group leader of Research and Development for Surgitek, a urological device manufacturer in Racine, Wisconsin, which was the market leader in ureteral stents. I recognized the need for an industry standard for ureteral stents, felt that taking a leadership role in the development of a new standard would be a good professional development activity, and volunteered to serve as the chair of the American Society for Testing and Materials (ASTM, now known as ASTM International) Task Group on Ureteral Stents. After several years, the standard was approved, and I continue to serve as the chair of the ASTM Subcommittee on Urological Materials and Devices. This experience helped me understand the value of industry standards, expanded my professional network and visibility within the medical device industry, and helped develop my leadership skills.

  18. Metallic stents in the management of ureteric strictures

    PubMed Central

    Kulkarni, Ravi

    2014-01-01

    Management of ureteric strictures is a challenging task. Subtle presentation, silent progression and complex aetiology may delay diagnosis. A wide range of available treatment options combined with the lack of adequate randomised trials has led to the introduction of personal bias in the management of this difficult group of patients. Metallic ureteric stents offer an alternative to the conventional treatment modalities. A review of the currently available metallic stents and their role in the long-term management of ureteric strictures is presented. Materials used in the manufacture of indwelling urological devices are evolving all the time. Improved endo-urological techniques combined with new devices made from better compounds will continue to improve patient experience. PMID:24497686

  19. Sequential compression devices in postoperative urologic patients: an observational trial and survey study on the influence of patient and hospital factors on compliance.

    PubMed

    Ritsema, David F; Watson, Jennifer M; Stiteler, Amanda P; Nguyen, Mike M

    2013-04-11

    Sequential compression devices (SCDs) are commonly used for thromboprophylaxis in postoperative patients but compliance is often poor. We investigated causes for noncompliance, examining both hospital and patient related factors. 100 patients undergoing inpatient urologic surgery were enrolled. All patient had SCD sleeves placed preoperatively. Postoperative observations determined SCD compliance and reasons for non-compliance. Patient demographics, length of stay, inpatient unit type, and surgery type were recorded. At discharge, a patient survey gauged knowledge and attitudes regarding SCDs and bother with SCDs. Statistical analysis was performed to correlate SCD compliance with patient demographics; patient knowledge and attitudes regarding SCDs; and patient self-reported bother with SCDs. Observed overall compliance was 78.6%. The most commonly observed reasons for non-compliance were SCD machines not being initially available on the ward (71% of non-compliant observations on post-operative day 1) and SCD use not being restarted promptly after return to bed (50% of non-compliant observations for entire hospital stay). Mean self-reported bother scores related to SCDs were low, ranging from 1-3 out of 10 for all 12 categories of bother assessed. Patient demographics, knowledge, attitudes and bother with SCD devices were not significantly associated with non-compliance. Patient self-reported bother with SCD devices was low. Hospital factors, including SCD machine availability and timely restarting of devices by nursing staff when a patient returns to bed, played a greater role in SCD non-compliance than patient factors. Identifying and addressing hospital related causes for poor SCD compliance may improve postoperative urologic patient safety.

  20. Laser Application in Iran Urology: A Narrative Review

    The usage of laser in medicine is not recent, and its history in urology goes back to 40 years ago. For the last 2 decades, common uses of laser have been treatments of subjects with urolithiasis, bladder tumors, benign prostatic enlargement, lesions of the genitalia and urinary tract strictures. To evaluate laser application in urology in Iran, we reviewed all of the Iranian literature on the topic. This study was designed to retrieve all studies on laser application in urology in Iran, regardless of publication status or language, covering years 1990–2017. Twenty-six articles were identified: 12 about urolithiasis, 8 about benign prostatic hyperplasia (BPH), 2 case reports, 1 paper about prostate cancer, 1 on female urethral stricture, 1 review and 1 basic sciences study. We conclude that the use of this technology has not yet found its position in Iran, especially in the field of urology. The main causes for it are the difficult accessibility and disturb of laser devices and its accessories, as well as the lack of adequate knowledge of the medical community about this modality.

  10. Emerging needle ablation technology in urology.

    PubMed

    Leveillee, Raymond J; Pease, Karli; Salas, Nelson

    2014-01-01

    Thermal ablation of urologic tumors in the form of freezing (cryoablation) and heating (radiofrequency ablation) have been utilized successfully to treat and ablate soft tissue tumors for over 15 years. Multiple studies have demonstrated efficacy nearing that of extirpative surgery for certain urologic conditions. There are technical limitations to their speed and safety profile because of the physical limits of thermal diffusion. Recently, there has been a desire to investigate other forms of energy in an effort to circumvent the limitations of cryoblation and radiofrequency ablation. This review will focus on three relatively new energy applications as they pertain to tissue ablation: microwave, irreversible electroporation, and water vapor. High-intensity-focused ultrasound nor interstitial lasers are discussed, as there have been no recently published updates. Needle and probe-based ablative treatments will continue to play an important role. As three-dimensional imaging workstations move from the advanced radiologic interventional suite to the operating room, surgeons will likely still play a pivotal role in the +-application of these probe ablative devices. It is essential that the surgeon understands the fundamentals of these devices in order to optimize their application.

    OnabotulinumtoxinA (onaBNTa) for treating neurogenic detrusor overactivity (NDO) is widely used after its regulatory approval in adults. Although the administration of onaBNTa is still considered off-label in children, data have already been reported on its efficacy and safety. Nowadays, there is a lack of standardized protocols for treatment of NDO with onaBNTa in adolescent patients in their transition from the childhood to the adult age. With the aim to address this issue a consensus panel was obtained. A panel of leading urologists and urogynaecologists skilled in functional urology, neuro-urology, urogynaecology, and pediatric urology participated in a consensus-forming project using a Delphi method to reach national consensus on NDO-onaBNTa treatment in adolescence transitional care. In total, 11 experts participated. All panelists participated in the four phases of the consensus process. Consensus was reached if ≥70% of the experts agreed on recommendations. To facilitate a common understanding among all experts, a face-to-face consensus meeting was held in Rome in march 2015 and then with a follow-up teleconference in march 2017. By the end of the Delphi process, formal consensus was achieved for 100% of the items and an algorithm was then developed. This manuscript represents the first report on the onaBNTa in adolescents. Young adults should be treated as a distinct sub-population in policy, planning, programming, and research, as strongly sustained by national public health care. This consensus and the algorithm could support multidisciplinary communication, reduce the extent of variations in clinical practice and optimize clinical decision making. © 2017 Wiley Periodicals, Inc.

  5. Sequential compression devices in postoperative urologic patients: an observational trial and survey study on the influence of patient and hospital factors on compliance

    PubMed Central

    2013-01-01

    Background Sequential compression devices (SCDs) are commonly used for thromboprophylaxis in postoperative patients but compliance is often poor. We investigated causes for noncompliance, examining both hospital and patient related factors. Methods 100 patients undergoing inpatient urologic surgery were enrolled. All patient had SCD sleeves placed preoperatively. Postoperative observations determined SCD compliance and reasons for non-compliance. Patient demographics, length of stay, inpatient unit type, and surgery type were recorded. At discharge, a patient survey gauged knowledge and attitudes regarding SCDs and bother with SCDs. Statistical analysis was performed to correlate SCD compliance with patient demographics; patient knowledge and attitudes regarding SCDs; and patient self-reported bother with SCDs. Results Observed overall compliance was 78.6%. The most commonly observed reasons for non-compliance were SCD machines not being initially available on the ward (71% of non-compliant observations on post-operative day 1) and SCD use not being restarted promptly after return to bed (50% of non-compliant observations for entire hospital stay). Mean self-reported bother scores related to SCDs were low, ranging from 1–3 out of 10 for all 12 categories of bother assessed. Patient demographics, knowledge, attitudes and bother with SCD devices were not significantly associated with non-compliance. Conclusions Patient self-reported bother with SCD devices was low. Hospital factors, including SCD machine availability and timely restarting of devices by nursing staff when a patient returns to bed, played a greater role in SCD non-compliance than patient factors. Identifying and addressing hospital related causes for poor SCD compliance may improve postoperative urologic patient safety. PMID:23578129

    2010-01-01

    Minimally invasive urology is rapidly advancing, and single-site laparoscopic surgery is being explored clinically. Such laparoscopic procedures are technically challenging and require an experienced laparoscopic surgeon due to the lack of port placement triangulation and instrument clashing. In the last years several surgeons all over the world have explored the feasibility and safety of LESS using several and different ports, approaches and devices. Hundreds of procedures have been described with overall favorable intraoperative and postoperative outcomes. Our experience consists of more than 30 procedures successfully completed for adrenal, kidney disease and varicocele. To date, LESS could be considered feasible and effective using currently available devices, however it is to be considered as an initial status technique requiring further confirmatory studies and advanced laparoscopic skills.

    The burden of urological diseases on the American public is immense in human and financial terms but it has been under studied. We undertook a project, Urologic Diseases in America, to quantify the burden of urological diseases on the American public. We identified public and private data sources that contain population based data on resource utilization by patients with benign and malignant urological conditions. Sources included the Centers for Medicare and Medicaid Services, National Center for Health Statistics, Medical Expenditure Panel Survey, National Health and Nutrition Examination Survey, Department of Veterans Affairs, National Association of Children's Hospitals and Related Institutions, and private data sets maintained by MarketScan Health and Productivity Management (MarketScan, Chichester, United Kingdom), Ingenix (Ingenix, Salt Lake City, Utah) and Center for Health Care Policy and Evaluation. Using diagnosis and procedure codes we described trends in the utilization of urological services. In 2000 urinary tract infections accounted for more than 6.8 million office visits and 1.3 million emergency room visits, and 245,000 hospitalizations in women with an annual cost of more than 2.4 billion dollars. Urinary tract infections accounted for more than 1.4 million office visits, 424,000 emergency room visits and 121,000 hospitalizations in men with an annual cost of more than 1 billion dollars. Benign prostatic hyperplasia was the primary diagnosis in more than 4.4 million office visits, 117,000 emergency room visits and 105,000 hospitalizations, accounting for 1.1 billion dollars in expenditures that year. Urolithiasis was the primary diagnosis for almost 2 million office visits, more than 600,000 emergency room visits, and more than 177,000 hospitalizations, totaling more than 2 billion dollars in annual expenditures. Urinary incontinence in women was the primary cause for more than 1.1 million office visits in 2000 and 452 million dollars in aggregate primary cause for more than 1.1 million office visits in 2000 and 452 million dollars in aggregate annual expenditures. Other manuscripts in this series present further detail for specific urologic conditions. Recent trends in epidemiology, practice patterns, resource utilization and costs for urological diseases have broad implications for quality of health care, access to care and the equitable allocation of scarce resources for clinical care and research.

    In August 2015, an expert colloquium commissioned by the Sexual Medicine Society of North America (SMSNA) convened in Washington, DC, to discuss the common clinical scenario of men who present with low testosterone (T) and associated signs and symptoms accompanied by low or normal gonadotropin levels. This syndrome is not classical primary (testicular failure) or secondary (pituitary or hypothalamic failure) hypogonadism because it may have elements of both presentations. The panel designated this syndrome adult-onset hypogonadism (AOH) because it occurs commonly in middle-age and older men. The SMSNA is a not-for-profit society established in 1994 to promote, encourage, and support the highest standards of practice, research, education, and ethics in the study of human sexual function and dysfunction. The panel consisted of 17 experts in men's health, sexual medicine, urology, endocrinology, and methodology. Participants declared potential conflicts of interest and were SMSNA members and nonmembers. The panel deliberated regarding a diagnostic process to document signs and symptoms of AOH, the rationale for T therapy, and a monitoring protocol for T-treated patients. The evaluation and management of hypogonadal syndromes have been addressed in recent publications (ie, the Endocrine Society, the American Urological Association, and the International Society for Sexual Medicine). The primary purpose of this document was to support health care professionals in the development of a deeper understanding of AOH, particularly in how it differs from classical primary and secondary hypogonadism, and to provide a conceptual framework to guide its diagnosis, treatment, and follow-up.

    Prostate cancer still represents a major cause of morbidity, and still about 20% of men with the disease are diagnosed or will progress to the advanced stage without the possibility of curative treatment. Despite the recent advances in scientific and technological knowledge and the availability of new therapies, there is still considerable heterogeneity in the therapeutic approaches for metastatic prostate cancer. This article presents a summary of the I Brazilian Consensus on Advanced Prostate Cancer, conducted by the Brazilian Society of Urology and Brazilian Society of Clinical Oncology. Experts were selected by the medical societies involved. Forty issues regarding controversial issues in advanced disease were previously elaborated. The panel met for consensus, with a threshold established for 2/3 of the participants. The treatment of advanced prostate cancer is complex, due to the existence of a large number of therapies, with different response profiles and toxicities. The panel addressed recommendations on preferred choice of therapies, indicators that would justify their change, and indicated some strategies for better sequencing of treatment in order to maximize the potential for disease control with the available therapeutic arsenal. The lack of consensus on some topics clearly indicates the absence of strong evidence for some decisions. Copyright® by the International Brazilian Journal of Urology.

    The transforming field of urological surgery continues to demand development of novel training devices and curricula for its trainees. Contemporary trainees have to balance workplace demands while overcoming the cognitive barriers of acquiring skills in rapidly multiplying and advancing surgical techniques. This article provides a brief review of the process involved in developing a surgical curriculum and the current status of real and simulation-based curricula in the 4 subgroups of urological surgical practice: open, laparoscopic, endoscopic, and robotic. An informal literature review was conducted to provide a snapshot into the variety of simulation training tools available for technical and nontechnical urological surgical skills within all subgroups of urological surgery using the following keywords: "urology, surgery, training, curriculum, validation, non-technical skills, technical skills, LESS, robotic, laparoscopy, animal models." Validated training tools explored in research were tabulated and summarized. A total of 20 studies exploring validated training tools were identified. Huge variation was noticed in the types of validity sought by researchers and suboptimal incorporation of these tools into curricula was noted across the subgroups of urological surgery. The following key recommendations emerge from the review: adoption of simulation-based curricula in training; better integration of dedicated training time in simulated environments within a trainee's working hours; better incentivization for educators and assessors to improvise, research, and deliver teaching using the technologies available; and continued emphasis on developing nontechnical skills in tandem with technical operative skills. © 2013 Published by Association of Program Directors in Surgery on behalf of Association of Program Directors in Surgery.

    Endoscopy enables minimally invasive procedures in many medical fields, such as urology. However, current endoscopes are normally cable-driven, which limits their dexterity and makes them hard to miniaturize. Indeed, current urological endoscopes have an outer diameter of about 3 mm and still only possess one bending degree-of-freedom. In this article, we report a novel wireless actuation mechanism that increases the dexterity and that permits the miniaturization of a urological endoscope. The novel actuator consists of thin active surfaces that can be readily attached to any device and are wirelessly powered by ultrasound. The surfaces consist of two-dimensional arrays of microbubbles, which oscillate under ultrasound excitation and thereby generate an acoustic streaming force. Bubbles of different sizes are addressed by their unique resonance frequency, thus multiple degrees-of-freedom can readily be incorporated. Two active miniaturized devices (with a side length of around 1 mm) are demonstrated: a miniaturized mechanical arm that realizes two degrees-of-freedom, and a flexible endoscope prototype equipped with a camera at the tip. With the flexible endoscope, an active endoscopic examination is successfully performed in a rabbit bladder. The results show the potential medical applicability of surface actuators wirelessly powered by ultrasound penetrating through biological tissues.

  5. The holmium laser in urology.

    PubMed

    Wollin, T A; Denstedt, J D

    1998-02-01

    To review the physics related to the holmium laser, its laser-tissue interactions, and its application to the treatment of urological diseases. The holmium: YAG laser is a solid-state, pulsed laser that emits light at 2100 nm. It combines the qualities of the carbon dioxide and neodymium:YAG lasers providing both tissue cutting and coagulation in a single device. Since the holmium wavelength can be transmitted down optical fibers, it is especially suited for endoscopic surgery. The authors provide a review of the literature as it relates to the holmium laser and its application to urology. The holmium wavelength is strongly absorbed by water. Tissue ablation occurs superficially, providing for precise incision with a thermal injury zone ranging from 0.5 to 1.0 mm. This level of coagulation is sufficient for adequate hemostasis. The most common urologic applications of the holmium laser that have been reported include incision of urethral and ureteral strictures; ablation of superficial transitional cell carcinoma; bladder neck incision and prostate resection; and lithotripsy of urinary calculi. The holmium: YAG laser is a multi-purpose, multi-specialty surgical laser. It has been shown to be safe and effective for multiple soft tissue applications and stone fragmentation. Its utilization in urology is anticipated to increase with time as a result of these features.

    Throughout the history, many devices have been used for breaking urinary tract stones. StoneBreaker (LMA Urology, Gland, Switzerland) is a second generation of intracorporeal lithotripter, pneumatic and portable, which adds several new advantages, like effectiveness in stone fragmentation and easy handling, very useful during percutaneous lithotripsy. We report the case of a 40 year-old male patient, with a left kidney pyelic lithiasis, who was treated by percutaneous lithotripsy, under general anaesthesia, with StoneBreaker (LMA Urology, Gland, Switzerland) as lithotripter. StoneBreaker (LMA Urology, Gland, Switzerland) is a lithotripter usable with rigid and semirigid ureteroscopes, much more powerful than its predecessors. It is able to decrease the number of shocks necessary for stone fragmentation, without bigger tissue reaction. It also has a more comfortable design due to the absence of connections, and its power by replaceable carbon dioxide cartridges.

  7. Determining Resident Sleep During and After Call With Commercial Sleep Monitoring Devices.

    Morhardt, Duncan R; Luckenbaugh, Amy; Goldstein, Cathy; Faerber, Gary J

    2017-08-01

    To demonstrate that commercial activity monitoring devices (CAMDs) are practical for monitoring resident sleep while on call. Studies that have directly monitored resident sleep are limited, likely owing to both cost and difficulty in study interpretation. The advent of wearable CAMDs that estimate sleep presents the opportunity to more readily evaluate resident sleep in physically active settings and "home call," a coverage arrangement familiar to urology programs. Twelve urology residents were outfitted with Fitbit Flex devices during "home call" for a total of 57 (out of 64, or 89%) call or post-call night pairs. Residents were surveyed with the Stanford Sleepiness Scale (SSS), a single-question alertness survey. Time in bed (TIB) was "time to bed" to "rise for day." Fitbit accelerometers register activity as follows: (1) not moving; (2) minimal movement or restless; or (3) above threshold for accelerometer to register steps. Total sleep time (TST) was the number of minutes in level 1 activity during TIB. Sleep efficiency (SE) was defined as TST divided by TIB. While on call, 10 responding (of 12 available, 83%) residents on average reported TIB as 347 minutes, TST as 165 minutes, and had an SE of 47%. Interestingly, SSS responses did not correlate with sleep parameters. Post-call sleep demonstrated increases in TIB, SE, and TST (+23%, +15%, and +44%, respectively) while sleepiness was reduced by 22%. We demonstrate that urologic residents can consistently wear CAMDs while on home call. SSS did not correlate with Fitbit-estimated sleep duration. Further study with such devices may enhance sleep deprivation recognition to improve resident sleep. Copyright © 2017 Elsevier Inc. All rights reserved.

    This randomized controlled study compared a novel transparent urinary tract simulator with the traditional opaque urinary tract simulator as an aid for efficiently teaching urological surgical procedures. Senior medical students were tested on their understanding of urological theory before and after lectures concerning urinary system disease. The students received operative training using the transparent urinary tract simulator (experimental group, n = 80) or the J3311 opaque plastic urinary tract simulator (control, n = 80), specifically in catheterization and retrograde double-J stent implantation. The operative training was followed by a skills test and student satisfaction survey. The test scores for theory were similar between the two groups, before and after training. Students in the experimental group performed significantly better than those in the control group on the procedural skills test, and also had significantly better self-directed learning skills, analytical skills, and greater motivation to learn. During the initial step of training, the novel transparent urinary tract simulator significantly improved the efficiency of teaching urological procedural skills compared with the traditional opaque device. © 2015 S.

    Digital media have revolutionized communication and information dissemination in healthcare. We aimed to quantify and evaluate professional digital media use among urology residents. We designed a 17-item survey to assess usage and perceived usefulness of digital media, as well as communication type and device type and distributed it via email to 143 Canadian and 721 German urology residents. In total, 58 (41% response rate) residents from Canada and 170 (24% response rate) from Germany reported professional usage rates of 100% on the internet, 89% on apps, and 46% on social media (SoMe). For professional use, residents spent a median of 30 minutes per day on the internet, 10 minutes on apps, and 15 minutes on SoMe. 100% rated the internet, 89% apps, and 31% SoMe as useful for clinical practice. Most (94%) used digital media for communication with colleagues and 23% for communication with patients. Digital media use was allocated to desktop computers (55%) and mobile devices (45%). Canadian residents had higher usage rates of apps (96% vs. 86%; p=0.042) and SoMe (65% vs. 39%; p=0.002) and longer daily usage times for the internet, apps, and SoMe than German residents (p<0.001 each). Digital media are an integral part of the daily professional practice of urology residents, reflected by high usage rates and perceived usefulness of the internet and apps, and the growing importance of SoMe. Urologists should strive to progressively exhaust the vast potential of digital media for academic and clinical practice.

    A display system includes a waveguide optical panel having an inlet face and an opposite outlet face. A projector cooperates with a digital imaging device, e.g. a digital micromirror imaging device, for projecting an image through the panel for display on the outlet face. The imaging device includes an array of mirrors tiltable between opposite display and divert positions. The display positions reflect an image light beam from the projector through the panel for display on the outlet face. The divert positions divert the image light beam away from the panel, and are additionally used for reflecting a probe light beam through the panel toward the outlet face. Covering a spot on the panel, e.g. with a finger, reflects the probe light beam back through the panel toward the inlet face for detection thereat and providing interactive capability.

    The rate of postoperative complications might vary according to the method used to collect perioperative data. We aimed at assessing the impact of the prospective implementation of the European Association of Urology (EAU) guidelines on reporting and grading of complications in prostate cancer patients undergoing robot-assisted radical prostatectomy (RARP). From September 2016, an integrated method for reporting surgical morbidity based on the EAU guidelines was implemented at a single, tertiary center. Perioperative data were prospectively and systematically collected during a patient interview at 30 d after surgery as recommended by the EAU Guidelines Panel Recommendations on Reporting and Grading Complications. The rate and grading of complications of 167 patients who underwent RARP±pelvic lymph node dissection (PLND) after the implementation of the prospective collection system (Group 1) were compared with 316 patients treated between January 2015 and August 2016 (Group 2) when a system based on patient chart review was used. No differences were observed in disease characteristics and PLND between the two groups (all p≥0.1). Postoperative complications were graded according to the Clavien-Dindo classification system. Overall, the complication rate was higher when the prospective collection system based on the EAU guidelines was used (29%) than when retrospective chart review (10%; p<0.001) was used. In particular, a substantially higher rate of grade 1 (8.4% vs 4.7%) and 2 (14% vs 2.8%) complications was detected in Group 1 versus Group 2 (p<0.001). Although the rate of complications occurred during hospitalization did not differ (13% vs 10%; p=0.3), 31 (19%) complications after discharge were detected in Group 1. This resulted into a readmission rate of 16%. Conversely, no complications after discharge and readmissions were recorded for Group 2. The implementation of the EAU guidelines on reporting perioperative outcomes roughly doubled the complication rate after RARP and allowed for the detection of complications after discharge in more than 15% of patients that would have been otherwise missed, where patients assessed with the EAU implemented protocol had a threefold higher likelihood of reporting complications. The implementation of the European Association of Urology guidelines on reporting and grading of complications after urologic procedures in prostate cancer patients roughly doubled the complication rate after robot-assisted radical prostatectomy compared to retrospective patient chart review. Moreover, it allowed for the detection of complications after discharge in more than 15% of patients that would have been otherwise missed. Copyright © 2018 European Association of Urology.

    To summarize the discussion that took place at a public workshop, co-sponsored by the U.S. Food and Drug Administration, the American Urological Association, and Society of Urologic Oncology reviewing the current state of the art for partial gland ablation (PGA) for the management of patients with prostate cancer. The purpose of this workshop was to discuss potential indications, current available evidence, and designs for future trials to provide the evidence needed by patients and providers to decide how and when to use PGA. A workshop evaluating PGA for prostate cancer was held in New Orleans, Louisiana, in May 2015. Invited experts representing all stakeholders and attendees discussed the regulatory development of medical products, technology available, potential indications, and designs of trials to evaluate this modality of therapy. The panel presented the current information on the technologies available to perform PGA, the potential indications, and results of prior consensus conferences. Use of magnetic resonance imaging for patient selection, guide therapy, and follow-up was discussed. Designs of trials to assess PGA outcomes were discussed. The general consensus was that currently available technologies are capable of selective ablation with reasonable accuracy, but that criteria for patient selection remain debatable, and long-term cancer control remains to be established in properly designed and well-performed prospective clinical trials. Concerns include the potential for excessive, unnecessary use in patients with low-risk cancer and, conversely, that current diagnostic techniques may underestimate the extent and aggressiveness of some cancers, leading to inadequate treatment.

    To review the minimal-invasive development of surgical technique in urology focusing on nomenclature, history and outcomes of Laparo-Endoscopic Single-site Surgery (LESS), Natural Orifice Translumenal Endoscopic Surgery (NOTES) and Computer-Assisted Surgery (CAS). A comprehensive literature search was conducted in order to find article related to LESS, NOTES and CAS in urology. The most relevant papers over the last 10 years were selected in base to the experience from the panel of experts, journal, authorship and/or content. Seven hundred and fifty manuscripts were found. Papers on LESS describe feasibility/safety in most of the procedures with a clinical experience of more than 300 cases and five compared results to standard laparoscopy without showing significant differences. NOTES accesses have been proved their feasibility/safety in experimental study. In human, the only procedures performed are on kidney and through a hybrid-Transvaginal route. New robots overcome the main drawbacks of the DaVinci® platform. The use of CAS is increasing its popularity in urology. LESS has been applied in clinical practice, but only ongoing technical and instrumental refinement will define its future role and overall benefit. The transition to a clinical application of NOTES seems at present only possible with multiple NOTES access and transvaginal access. Robot and Soft Tissue Navigation appear to be important to improve surgical skills. We are already witness to the advantages offered by the former even if costs need to be redefined based on pending long-term results. The latter will probably upgrade the quality of surgery in a near future.

    Following a patient complaint, the Health Department carried out a hygiene inspection of a urological practice in Braunschweig in February 2013. The topic of the complaint was that a patient assumed having acquired a resistant pathogen in the practice. In the subsequent visit, significant hygiene defects were found, particularly with regard to the processing of medical devices. This led to a decision to commit all urological practices in Braunschweig to hygiene inspections as part of a priority project. In retrospect, the hygiene surveys were justified. Deficiencies included inadequate preparation of medical products, procedures in practice inconsistent with hygiene plans, poor knowledge of hygiene procedures among assistant staff and doctors, lack of expertise of assistant staff and lack of hygiene risk awareness by doctors. Positive experiences were: open communication in a good atmosphere with the Practice managers, willingness to change, good cooperation between the Health Authority and the Labor Inspectorate and Physicians' Association. The claimed deficits were corrected by spring 2014 by the practice operators. The consulting expertise of the health authorities was made use of continuously. © Georg Thieme Verlag KG Stuttgart · New York.

  20. Re-active Passive (RAP) Devices for Control of Noise Transmission through a Panel

    2008-01-01

    Re-Active Passive (RAP) devices have been developed to control low frequency (<1000 Hz) noise transmission through a panel. These devices use a combination of active, re-active, and passive technologies packaged into a single unit to control a broad frequency range utilizing the strength of each technology over its best suited frequency range. The RAP device uses passive constrained layer damping to cover the relatively high frequency range (>200 Hz), reactive distributed vibration absorber) to cover the medium frequency range (75 to 250 Hz), and active control for controlling low frequencies (<200 Hz). The device was applied to control noise transmission through a panel mounted in a transmission loss test facility. Experimental results are presented for the bare panel, and combinations of passive treatment, reactive treatment, and active control. Results indicate that three RAP devices were able to increase the overall broadband (15-1000 Hz) transmission loss by 9.4 dB. These three devices added a total of 285 grams to the panel mass of 6.0 kg, or approximately 5%, not including control electronics.

    2017-04-01

    To shorten the stopping distance of the high speed trains in case of emergency, we developed a small-sized aerodynamic braking unit without use of the friction between a rail and a wheel. The developed device could actuate a pair of two drag panels with a travelling wind. However, after the drag panel fully opened, vibrational movements of the drag panel characterized by its slight flutter were repeated. In this study, to stabilize the opened panel, matters pertaining to the angle of attack with respect to the drag panel and pertaining to the arrangement of the two panels were examined by a wind tunnel experiment using a scale model. As a result, to stabilize the opened panel and to keep the good performance of the braking device, it is found out that an angle of attack of 75 to 80 degrees is suitable provided that the interval of the two panels is narrow enough.

    We report the novel use of 3-charge coupled device camera technology to infer tissue oxygenation. The technique can aid surgeons to reliably differentiate vascular structures and noninvasively assess laparoscopic intraoperative changes in renal tissue perfusion during and after warm ischemia. We analyzed select digital video images from 10 laparoscopic partial nephrectomies for their individual 3-charge coupled device response. We enhanced surgical images by subtracting the red charge coupled device response from the blue response and overlaying the calculated image on the original image. Mean intensity values for regions of interest were compared and used to differentiate arterial and venous vasculature, and ischemic and nonischemic renal parenchyma. The 3-charge coupled device enhanced images clearly delineated the vessels in all cases. Arteries were indicated by an intense red color while veins were shown in blue. Differences in mean region of interest intensity values for arteries and veins were statistically significant (p >0.0001). Three-charge coupled device analysis of pre-clamp and post-clamp renal images revealed visible, dramatic color enhancement for ischemic vs nonischemic kidneys. Differences in the mean region of interest intensity values were also significant (p <0.05). We present a simple use of conventional 3-charge coupled device camera technology in a way that may provide urological surgeons with the ability to reliably distinguish vascular structures during hilar dissection, and detect and monitor changes in renal tissue perfusion during and after warm ischemia.

    People with asymptomatic bacteriuria (ABU) are often unnecessarily treated with antibiotics risking adverse effects and antimicrobial resistance. We performed a systematic review to determine any benefits and harms of treating ABU in particular patient groups. Relevant databases were searched and eligible trials were assessed for risk-of-bias and Grading of Recommendations, Assessment, Development and Education quality. Where possible, a meta-analysis of extracted data was performed or a narrative synthesis of the evidence was presented. After screening 3626 articles, 50 studies involving 7088 patients were included. Overall, quality of evidence ranged from very low to low. There was no evidence of benefit for patients with no risk factors, patients with diabetes mellitus, postmenopausal women, elderly institutionalised patients, patients with renal transplants, or patients prior to joint replacement, and treatment was harmful for patients with recurrent urinary tract infection (UTI). Treatment of ABU resulted in a lower risk of postoperative UTI after transurethral resection surgery. In pregnant women, we found evidence that treatment of ABU decreased risk of symptomatic UTI, low birthweight, and preterm delivery. ABU should be treated prior to transurethral resection surgery. In addition, current evidence also suggests that ABU treatment is required in pregnant women, although the results of a recent trial have challenged this view. We reviewed available scientific studies to see if people with bacteria in their urine but without symptoms of urinary tract infection should be treated with antibiotics to eliminate bacteria. For most people, treatment was not beneficial and may be harmful. Antibiotic treatment did appear to benefit women in pregnancy and those about to undergo urological surgery.

    2016-04-01

    Reservoir placement during implantation of prosthetic urology devices has been problematic throughout the history of the surgical treatment of erectile dysfunction and urinary incontinence. We thought it would be interesting to review the history of reservoir placement leading up to current surgical techniques. To provide an overview of the past and present techniques for reservoir placement and discuss the evolutionary process leading to safe and effective placement of prosthetic reservoirs. We reviewed data pertaining to inflatable penile prosthesis (IPP) reservoirs and pressure-regulating balloons (PRB) in a chronological fashion, spanning 25 years. Main outcomes included a historical review of techniques for IPP reservoir and PRB placement leading to the subsequent incremental improvements in safety and efficacy when performing penile implants and artificial urinary sphincters. Prosthetic urologic reservoirs have traditionally been placed in the retropubic space. Over the years, urologists have attempted use of alternative spaces including peritoneal, epigastric, "ectopic," posterior to transversalis, and high submuscular. Current advances in prosthetic urologic reservoir placement allow safe and effective abdominal wall placement of reservoirs. These novel approaches appear to be so effective that urologists may now be able to cease using the traditional retropubic space for reservoir placement, even in the case of virgin pelves.

    2007-09-01

    The ability of a commercially available panel reader system to read International Standards Organization-compliant electronic identification devices under commercial dairy conditions was examined. Full duplex (FDX-B) and half-duplex (HDX) low frequency radio-frequency identification external ear tags were utilized. The study involved 498 Holstein cows in the final 6 wk of gestation. There were 516 total electronic identification devices (n = 334 HDX and n = 182 FDX-B). Eighteen FDX-B were replaced with HDX during the study due to repeated detection failure. There were 6,679 HDX and 3,401 FDX-B device detection attempts. There were 220 (2.2%) unsuccessful and 9,860 (97.8%) successful identification detection attempts. There were 9 unsuccessful detection attempts for HDX (6,670/6,679 = 99.9% successful detection attempts) and 211 unsuccessful detection attempts for FDX-B (3,190/3,401 = 93.8% successful detection attempts). These results demonstrate that this panel system can achieve high detection rates of HDX devices and meet the needs of the most demanding management applications. The FDX-B detection rate was not sufficient for the most demanding applications, requiring a high degree of detection by panel readers. The lower FDX-B rate may not be inherent in the device technology itself, but could be due to other factors, including the particular panel reader utilized or the tuning of the panel reader.

    A photovoltaic system includes multiple strings of solar panels and a device presenting a DC load to the strings of solar panels. Output currents of the strings of solar panels may be sensed and provided to a computer that generates current-voltage (IV) curves of the strings of solar panels. Output voltages of the string of solar panels may be sensed at the string or at the device presenting the DC load. The DC load may be varied. Output currents of the strings of solar panels responsive to the variation of the DC load are sensed to generate IV curves of the strings of solar panels. IV curves may be compared and analyzed to evaluate performance of and detect problems with a string of solar panels.

    2012-04-01

    The European Association of Urology (EAU) Guidelines Office has set up a guideline working panel to analyse the scientific evidence published in the world literature on lasers in urologic practice. Review the physical background and physiologic and technical aspects of the use of lasers in urology, as well as current clinical results from these new and evolving technologies, together with recommendations for the application of lasers in urology. The primary objective of this structured presentation of the current evidence base in this area is to assist clinicians in making informed choices regarding the use of lasers in their practice. Structured literature searches using an expert consultant were designed for each section of this document. Searches were carried out in the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, and Medline and Embase on the Dialog/DataStar platform. The controlled terminology of the respective databases was used, and both Medical Subject Headings and EMTREE were analysed for relevant entry terms. One Cochrane review was identified. Depending on the date of publication, the evidence for different laser treatments is heterogeneous. The available evidence allows treatments to be classified as safe alternatives for the treatment of bladder outlet obstruction in different clinical scenarios, such as refractory urinary retention, anticoagulation, and antiplatelet medication. Laser treatment for bladder cancer should only be used in a clinical trial setting or for patients who are not suitable for conventional treatment due to comorbidities or other complications. For the treatment of urinary stones and retrograde endoureterotomy, lasers provide a standard tool to augment the endourologic procedure. In benign prostatic obstruction (BPO), laser vaporisation, resection, or enucleation are alternative treatment options. The standard treatment for BPO remains transurethral resection of the prostate for small to moderate size prostates and open prostatectomy for large prostates. Laser energy is an optimal treatment method for disintegrating urinary stones. The use of lasers to treat bladder tumours and in laparoscopy remains investigational.

    1999-09-28

    An apparatus for constructing a subsurface containment barrier under a waste site disposed in soil is provided. The apparatus uses a reciprocating cutting and barrier forming device which forms a continuous elongate panel through the soil having a defined width. The reciprocating cutting and barrier forming device has multiple jets which eject a high pressure slurry mixture through an arcuate path or transversely across the panel being formed. A horizontal barrier can be formed by overlapping a plurality of such panels. The cutting device and barrier forming device is pulled through the soil by two substantially parallel pulling pipes which are directionally drilled under the waste site. A tractor or other pulling device is attached to the pulling pipes at one end and the cutting and barrier forming device is attached at the other. The tractor pulls the cutting and barrier forming device through the soil under the waste site without intersecting the waste site. A trailing pipe, attached to the cutting and barrier forming device, travels behind one of the pulling pipes. In the formation of an adjacent panel the trailing pipe becomes one of the next pulling pipes. This assures the formation of a continuous barrier.

  1. Solar panel parallel mounting configuration

    NASA Technical Reports Server (NTRS)

    Mutschler, Jr., Edward Charles (Inventor)

    1998-01-01

    A spacecraft includes a plurality of solar panels interconnected with a power coupler and an electrically operated device to provide power to the device when the solar cells are insolated. The solar panels are subject to bending distortion when entering or leaving eclipse. Spacecraft attitude disturbances are reduced by mounting each of the solar panels to an elongated boom made from a material with a low coefficient of thermal expansion, so that the bending of one panel is not communicated to the next. The boom may be insulated to reduce its bending during changes in insolation. A particularly advantageous embodiment mounts each panel to the boom with a single mounting, which may be a hinge. The single mounting prevents transfer of bending moments from the panel to the boom.

  2. Current controversies in pediatric urologic robotic surgery.

    PubMed

    Trevisani, Lorenzo F M; Nguyen, Hiep T

    2013-01-01

    Minimally invasive surgeries such as conventional laparoscopic surgery and robotic assisted laparoscopic surgery (RALS) have significant advantages over the traditional open surgical approach including lower pain medication requirements and decreased length of hospitalization. However, open surgery has demonstrated better success rates and shorter surgery time when compared to the other modalities. Currently, it is unclear which approach has better long-term clinical outcomes, greater benefits and less cost. There are limited studies in the literature comparing these three different surgical approaches. In this review, we will evaluate the advantages and disadvantages of RALS compared to conventional laparoscopic surgery and open surgery for commonly performed pediatric urological procedures such as pyeloplasty, ureteral reimplantation, complete and partial nephrectomy, bladder augmentation and creation of continent catheterizable channels. Although it is not yet possible to demonstrate the superiority of one single surgical modality over another, RALS has been shown to be feasible, well tolerated and advantageous in reconstructive urological procedures. With experience, the outcomes of RALS are improving, justifying its usage. However, cost remains a significant issue, limiting the accessibility of RALS, which in the future may improve with market competition and device innovation.

    This study aims to describe the discussions and recommendations made during the U.S. Food and Drug Administration (FDA) Circulatory System Device Panel pre-market approval application for the Absorb Bioresorbable Vascular Scaffold (BVS) System. The Absorb BVS System is a first-of-its-kind fully bioresorbable percutaneous coronary intervention technology. The absorb BVS was studied in the ABSORB III (A Clinical Evaluation of Absorb BVS, the Everolimus Eluting Bioresorbable Vascular Scaffold in the Treatment of Subjects with de Novo Native Coronary Artery Lesions) trial, the pivotal U.S. investigational device exemption trial. Observational report of the FDA Circulatory System Device Panel pre-market approval application meeting held on March 15, 2016. The U.S. FDA Circulatory System Device Panel members reviewed the ABSROB III trial outcomes and additional post hoc analyses presented by the sponsor and the FDA. The ABSORB III trial met the primary endpoint of noninferiority of Absorb BVS compared with the control, XIENCE drug-eluting stent, for target lesion failure at 1 year. Although a higher numerical trend for adverse outcomes was reported for the Absorb BVS, there were no statistical differences between Absorb BVS and XIENCE for any safety or effectiveness components for target lesion failure or for the secondary pre-specified outcomes. Panel members raised concerns with regard to the ABSORB III results and post hoc analyses focusing mainly on the noninferiority design of the trial, the apparent safety issues of the Absorb BVS in small vessels, the mismatch of visually versus intravascular imaging assessed vessel size found in ABSORB III and its implications on the adequate device labeling, the safety of Absorb BVS in specific patient and lesion subsets, and the post-approval commitments of the sponsor. Following panel discussions and the evidence presented, the panel voted for approval of the device. Copyright © 2016 American College of Cardiology Foundation. Published by Elsevier Inc.

    2015-01-01

    The purpose of this study was to clarify the contamination and cleaning of touch panels used in everyday life and the awareness of persons in charge and users of devices about contamination. Samples from touch panels were cultured to detect viable bacteria (n=132), Staphylococcus aureus (n=66) and Escherichia coli (n=64). A questionnaire survey was conducted on persons in charge and users of the devices on the day of sampling. Viable bacterial cells were detected in more than 90% of the automatic teller machines (ATMs) at banks, the ticket machines at stations, and the copy machines at convenience stores. S. aureus and E. coli were detected in more than one-half of such devices examined. The detection rate of viable bacterial cells in smartphones was 57.5% and was lower than those in other devices. More than 65% of the ATMs, ticket machines, and copy machines were cleaned once or twice a day. More than one-half of the users of smartphones or button-type mobile phones did not clean their devices. Those who did not aware about the contamination of touch panels were 46.6% of the persons in charge and 38.2% of the users. It is necessary to examine the suitable number of times and methods of cleaning of touch panels and to raise the awareness of persons in charge or users of such devices about contamination.

  8. Lynch Syndrome: A Primer for Urologists and Panel Recommendations.

    Lynch syndrome, also known as hereditary nonpolyposis colorectal cancer, is a common genetic disease. The predisposition of patients with Lynch syndrome to urological cancer, particularly upper tract urothelial carcinoma, is underappreciated. Urologists may be involved in several aspects of care involving Lynch syndrome, including identifying undiagnosed patients, surveillance of those with established Lynch syndrome or screening family members, in addition to treating patients with Lynch syndrome in whom upper tract urothelial carcinoma develops. We sought to increase awareness in the urological community about Lynch syndrome and provide some guidance where little currently exists. Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement we reviewed the available published literature and guidelines from 1998 to 2014 on Lynch syndrome and its association with upper tract urothelial carcinoma. Recommendations based on the literature and the consensus of expert opinion are provided. No randomized or prospective study has been done to evaluate Lynch syndrome in the setting of urological cancer. All data were based on retrospective studies. Lynch syndrome is an autosomal dominant genetic disease caused by germline mutations in 4 mismatch repair genes, leading to the accumulation of DNA errors in microsatellite regions. Upper tract urothelial carcinoma develops in up to 28% of patients with known Lynch syndrome. The diagnosis of Lynch syndrome is established by clinical criteria, tumor tissue testing and genetic evaluation. Urologists should suspect Lynch syndrome when a patient with upper tract urothelial carcinoma presents before age 60 years or meets the 3-2-1 rule. Screening patients with Lynch syndrome for upper tract urothelial carcinoma presents a particular challenge. While no ideal screening test exists, at a minimum routine urinalysis is recommended using the American Urological Association guideline of 3 or more red blood cells per high power field as a trigger for further assessment. Upper tract urothelial carcinoma associated with Lynch syndrome presents at a younger age than sporadic upper tract urothelial carcinoma. It shows a higher proportion of ureteral cancer with a female preponderance and a possible predisposition to bilaterality. Lynch syndrome is a common genetic disease that is an underappreciated cause of upper tract urothelial carcinoma and possibly other urological cancers. Optimal screening for upper tract urothelial carcinoma in this population is unclear. Further study is needed to identify the best screening test and interval of testing. Urologists should consider routine tissue testing of de novo upper tract urothelial carcinoma tissue in individuals at risk.

    Food and Drug Administration (FDA) advisory panels and committees play a critical role in advising the FDA on the safety and efficacy of medical devices and drugs marketed in the US. Advisory panel recommendations are used by the FDA to make decisions regarding medical products. Currently, the FDA utilizes over 50 advisory panels that serve the three major FDA centers, including the Centers for Biologics, Drugs and Device Products. Members of an advisory panel typically include academicians, clinicians, consumers, patients, and industry representatives. The FDA establishes the schedules for advisory panel meetings on an annual basis and a panel usually meets several times a year for two consecutive days in Washington, DC. Typically, the advisory panel discusses issues highlighted by the FDA and is then asked to vote a response to the questions posed in advance by the FDA. Advisory panel recommendations have a strong influence on FDA's decision to approve a product, as evidenced by the 214 Advisory Panels FDA convened between January 2008 to November 2012, during which advisory panel members voted to approve the product (or use of the product) ∼74% of the time, with FDA ultimately approving the medical product (or use of the product) ∼79% of the time. The ACG membership are encouraged to consider serving the public's interest by participating in an FDA advisory panel utilizing their expertise for the evaluation of a new drug or medical device, and providing advice about whether the product should be sold in the US.

    2007-12-05

    A telemanipulator for laparoscopic instruments is now available in the world of surgical robotics. This device has three distincts advantages over traditional laparoscopic surgery: it improves precision because of the many degrees of freedom of its instruments, and it offers 3-D vision so as better ergonomics for the surgeon. These characteristics are most useful for procedures that require delicate suturing in a focused operative field which may be difficult to reach. The Da Vinci robot has found its place in 2 domains of laparoscopic urologic surgery: radical prostatectomy and ureteral surgery. The cost of the robot, so as the price of its maintenance and instruments is high. This increases healthcare costs in comparison to open surgery, however not dramatically since patients stay less time in hospital and go back to work earlier.

  12. The Knowledge of Radiation and the Attitude Towards Radio-Protection among Urology Residents in India.

    Exposure to radiation is a hazard and precautions are necessary to limit it. This study was done to assess the knowledge of radiation and the attitude towards radio-protection among urology residents in India. A questionnaire was administered to assess the knowledge and attitude of urology residents who came from all over the country to attend a clinical meeting at Apollo Gleneagles Hospital, Kolkata, India. All the respondents agreed to being exposed to radiation, with 78.2% using radiation in more than five cases a week. Only 65.2% always took some steps for radio-protection. Lead aprons and thyroid shields were the most common radiation protection devices used. None of the residents ever used lead gloves or protective eye glasses or dosimeters. An 82.6% felt that they did not have adequate knowledge, 85.4% of residents did not receive any formal classes regarding the risk of radiation, 21.7% either rarely or never moved out of the operating room when the radiation was being used, 42.4% did not know that the SI unit of the equivalent absorbed dose of radiation & 52.1% did not know about the amount of radiation delivered to an adult during a contrast enhanced CT scan of the abdomen. Results of the present study reveal that the urology residents of India lack knowledge about the risks of radiation exposure. Majority of them did not take necessary precautions to limit their exposure to radiation.

    Crowdsourcing is the practice of obtaining services from a large group of people, typically an online community. Validated methods of evaluating surgical video are time-intensive, expensive, and involve participation of multiple expert surgeons. We sought to obtain valid performance scores of urologic trainees and faculty on a dry-laboratory robotic surgery task module by using crowdsourcing through a web-based grading tool called Crowd Sourced Assessment of Technical Skill (CSATS). IRB approval was granted to test the technical skills grading accuracy of Amazon.com Mechanical Turk™ crowd-workers compared to three expert faculty surgeon graders. The two groups assessed dry-laboratory robotic surgical suturing performances of three urology residents (PGY-2, -4, -5) and two faculty using three performance domains from the validated Global Evaluative Assessment of Robotic Skills assessment tool. After an average of 2 hours 50 minutes, each of the five videos received 50 crowd-worker assessments. The inter-rater reliability (IRR) between the surgeons and crowd was 0.91 using Cronbach's alpha statistic (confidence intervals=0.20-0.92), indicating an agreement level between the two groups of "excellent." The crowds were able to discriminate the surgical level, and both the crowds and the expert faculty surgeon graders scored one senior trainee's performance above a faculty's performance. Surgery-naive crowd-workers can rapidly assess varying levels of surgical skill accurately relative to a panel of faculty raters. The crowds provided rapid feedback and were inexpensive. CSATS may be a valuable adjunct to surgical simulation training as requirements for more granular and iterative performance tracking of trainees become mandated and commonplace.

    Since June 2012, the has been a worldwide lack of available of the Connaught strain. In December 2012, a group of experts met in the Spanish Association of Urology to analyze this situation and propose alternatives. To present the work performed by said committee and the resulting recommendations. An update has been made of the principal existing evidence in the treatment of middle and high risk tumors. Special mention has been made regarding the those related with the use of BCG and their possible alternative due to the different availability of BCG. In tumors with high risk of progression, immediate cystectomy should be considered when BCG is not available, with dose reduction or alternating with chemotherapy as methods to economize on the use of BCG when availability is reduced. In tumors having middle risk of progression, chemotherapy can be used, although when it is associated to a high risk of relapse, BCG would be indicated if available with the mentioned savings guidelines. BCG requires maintenance to maintain its effectiveness, it being necessary to optimize the application of endovesical chemotherapy and to use systems that increase its penetration into the bladder wall (EMDA) if they are available. Due to the scarcity of BCG, it has been necessary to agree on a series of recommendations that have been published on the web page of the Spanish Association of Urology. Copyright © 2013 AEU.

    As urology training shifts toward competency-based frameworks, the need for tools for high stakes assessment of trainees is crucial. Validated assessment metrics are lacking for many robot-assisted radical prostatectomy (RARP). As it is quickly becoming the gold standard for treatment of localized prostate cancer, the development and validation of a RARP assessment tool for training is timely. We recruited 13 expert RARP surgeons from the United States and Canada to serve as our Delphi panel. Using an initial inventory developed via a modified Delphi process with urology residents, fellows, and staff at our institution, panelists iteratively rated each step and sub-step on a 5-point Likert scale of agreement for inclusion in the final assessment tool. Qualitative feedback was elicited for each item to determine proper step placement, wording, and suggestions. Panelist's responses were compiled and the inventory was edited through three iterations, after which 100% consensus was achieved. The initial inventory steps were decreased by 13% and a skip pattern was incorporated. The final RARP stepwise inventory was comprised of 13 critical steps with 52 sub-steps. There was no attrition throughout the Delphi process. Our Delphi study resulted in a comprehensive inventory of intraoperative RARP steps with excellent consensus. This final inventory will be used to develop a valid and psychometrically sound intraoperative assessment tool for use during RARP training and evaluation, with the aim of increasing competency of all trainees.

    One of the priorities of the "Plan against the Cancer" in France is to ensure the discussion of all cancer cases in a multidisciplinary meeting staff (RCP). The multidisciplinary collaboration is proposed to guarantee a discussion between specialists in every cases, particularly in complex cases. The aim of this study was to compare the therapeutic decision taken in four RCP in Paris Île-de-France academic centres for three identical cases. Three cases of urological oncology (prostate cancer [PCa], renal cell carcinoma [RCC] and bladder tumour) were selected by a single urologist, not involved in further discussion. These cases were blindly presented in four academic urology department from Paris: Pitié-Salpêtrière Hospital, Mondor Hospital, the Georges-Pompidou European Hospital and Foch Hospital. The four centres met the criteria of quality of RCP in terms of multidisciplinarity, frequency and standardization. The therapeutic suggestions were similar in the RCC cases, there were differences in the surgical approaches and preoperative work-up in the PCa case and, lastly, the proposals were different for the bladder cancer case. The decisions relies on clinical data and preoperative work-up but also on the experience and habits of the centre of excellence. For complex cases that does not fit with current guidelines, the panel discussion can lead to different therapeutic options from a centre to another and is largely influenced by the local organisation of the RCP.

    Our aim was to understand the specific factors which influence medical students' choice to train in urology, in order to attract the best and the brightest into the specialty during a challenging time for surgical training in the United Kingdom A cross-sectional web-based survey was generated to evaluate: 1) perceptions of urology; 2) attitudes about urology as a career; 3) exposure to urology at medical school; and 4) proficiency in common urological procedures. The survey was sent to all 33 medical schools in the UK and advertised to all medical students. The survey received 488 responses were received from 14 medical schools; 59.8% of respondents did not consider a career in urology. Factors affecting a career choice in urology included: 1) year of study; 2) male gender; 3) favorable perceptions of urology; 4) favorable attitudes about urology as a career; 5) more hours of urology teaching in preclinical years; 6) attendance at urology theatre sessions; 7) confidence in performing urological procedures; and 8) more attempts at male catheterization. The commonest reason for not considering urology was inadequate exposure to urology. Students in Year 3 were more likely to consider urology than final-year students, due to multifactorial reasons. Year of study is a novel factor affecting students' consideration of urology as a career. This paper clearly shows that early and sustained exposure to urology positively correlated with considering a career in urology. Urologists must be more active in promoting the specialty to medical students.

  20. Implications of Biofilm Formation on Urological Devices

    Despite millions of dollars and several decades of research targeted at their prevention and eradication, biofilm-associated infections remain the major cause of urological device failure. Numerous strategies have been aimed at improving device design, biomaterial composition, surface properties and drug delivery, but have been largely circumvented by microbes and their plethora of attachment, host evasion, antimicrobial resistance, and dissemination strategies. This is not entirely surprising since natural biofilm formation has been going on for millions of years and remains a major part of microorganism survival and evolution. Thus, the fact that biofilms develop on and in the biomaterials and tissues of humans is really an extension of this natural tendency and greatly explains why they are so difficult for us to combat. Firstly, biofilm structure and composition inherently provide a protective environment for microorganisms, shielding them from the shear stress of urine flow, immune cell attack and some antimicrobials. Secondly, many biofilm organisms enter a metabolically dormant state that renders them tolerant to those antibiotics and host factors able to penetrate the biofilm matrix. Lastly, the majority of organisms that cause biofilm-associated urinary tract infections originate from our own oral cavity, skin, gastrointestinal and urogenital tracts and therefore have already adapted to many of our host defenses. Ultimately, while biofilms continue to hold an advantage with respect to recurrent infections and biomaterial usage within the urinary tract, significant progress has been made in understanding these dynamic microbial communities and novel approaches offer promise for their prevention and eradication. These include novel device designs, antimicrobials, anti-adhesive coatings, biodegradable polymers and biofilm-disrupting compounds and therapies.

    All devices which operate in space are exposed to cosmic rays during their operation. The resulting radiation may cause fatal damages in the solid structure of devices and the amount of absorbed radiation dose and secondary particle production for each component should be calculated carefully before the production. Solar panels are semiconductor solid state devices and are very sensitive to radiation. Even a short term power cut-off may yield a total failure of the satellite. Even little doses of radiation can change the characteristics of solar cells. This deviation can be caused by rarer high energetic particles as well as the total ionizing dose from the abundant low energy particles. In this study, solar panels planned for a specific LEO satellite, IMECE, are analyzed layer by layer. The Space Environment Information System (SPENVIS) database and GEANT4 simulation software are used to simulate the layers of the panels. The results obtained from the simulation will be taken in account to determine the amount of radiation protection and resistance needed for the panels or to revise the design of the panels.

    The Didusch Center for Urologic History encompasses a rich and varied collection of drawings, photographs, and instruments of historical importance to urology, many displayed in the urological exhibits during the American Urological Association (AUA) conventions. The Center also houses a library devoted to urological and early medical texts and the AUA archives and is the institution of research in all fields of urologic history in the USA. The museum collection features most of Didusch's original drawings, as well as an impressive instrument collection acquired primarily through donations by urologists. The original William P. Didusch Museum (now known as the William P. Didusch Center for Urologic History) was originally housed in the AUA's Baltimore City headquarters building. Upon the association's move to Linthicum, MD in 2003, the museum has evolved into the William P. Didusch Center for Urologic History and taken on new tasks and responsibilities that include the topic of research in urologic history.

  7. Development of a Classification Scheme for Examining Adverse Events Associated with Medical Devices, Specifically the DaVinci Surgical System as Reported in the FDA MAUDE Database.

    To examine the Manufacturer and User Facility Device Experience Database (MAUDE) database to capture adverse events experienced with the Da Vinci Surgical System. In addition, to design a standardized classification system to categorize the complications and machine failures associated with the device. Overall, 1,057,000 DaVinci procedures were performed in the United States between 2009 and 2012. Currently, no system exists for classifying and comparing device-related errors and complications with which to evaluate adverse events associated with the Da Vinci Surgical System. The MAUDE database was queried for events reports related to the DaVinci Surgical System between the years 2009 and 2012. A classification system was developed and tested among 14 robotic surgeons to associate a level of severity with each event and its relationship to the DaVinci Surgical System. Events were then classified according to this system and examined by using Chi-square analysis. Two thousand eight hundred thirty-seven events were identified, of which 34% were obstetrics and gynecology (Ob/Gyn); 19%, urology; 11%, other; and 36%, not specified. Our classification system had moderate agreement with a Kappa score of 0.52. Using our classification system, we identified 75% of the events as mild, 18% as moderate, 4% as severe, and 3% as life threatening or resulting in death. Seventy-seven percent were classified as definitely related to the device, 15% as possibly related, and 8% as not related. Urology procedures compared with Ob/Gyn were associated with more severe events (38% vs 26%, p < 0.0001). Energy instruments were associated with less severe events compared with the surgical system (8% vs 87%, p < 0.0001). Events that were definitely associated with the device tended to be less severe (81% vs 19%, p < 0.0001). Our classification system is a valid tool with moderate inter-rater agreement that can be used to better understand device-related adverse events. The majority of robotic related events were mild but associated with the device.

  8. Citation indices for social media articles in urology.

    2017-05-01

    To evaluate the impact of publications on urological participation in social media (SoMe) by virtue of citations in the urological and non-urological literature. On 15 March 2016, a PubMed search was undertaken using the names of the major SoMe platforms in current use and associated with the field of urology. The search term 'urolog*' was used to specifically capture articles that could be associated with 'urology', 'urologist' or 'urological'. Exclusion criteria for analysis included non-English language articles, articles published for the first time online in any form after 1 March 2015, articles irrelevant to the topic of SoMe, and letters of correspondence. Included articles were then searched in Google Scholar and citations analysed to determine if citations were from the urological literature or non-urological literature. Citations from non-urological journals were considered to be as such even if authored by urologists and on the subject of urology and SoMe. Prior to exclusions as defined in the methods, our PubMed search yielded 232 articles of which 17 were non-English language and 66 had been published after 1 March 2015. Allowing for 12 months after the most recent articles were published, we found that the mean number of total citations in any journal was 20.8. There were more citations in journals not specific to urology, with 8.3 citations in urological journals, compared to 12.6 citations in non-urological journals. Urological SoMe journal articles are highly cited, particularly in the non-urological literature. It is likely that the magnitude of citations has positively contributed to the impact factors of the almost all journals publishing these manuscripts. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

    There is a need to reduce the number of cystoscopies on patients with haematuria. Presently there are no reliable biomarkers to screen for bladder cancer. In this paper, we evaluate a new simple in–house fabricated, GC-sensor device in the diagnosis of bladder cancer based on volatiles. Sensor outputs from 98 urine samples were used to build and test diagnostic models. Samples were taken from 24 patients with transitional (urothelial) cell carcinoma (age 27-91 years, median 71 years) and 74 controls presenting with urological symptoms, but without a urological malignancy (age 29-86 years, median 64 years); results were analysed using two statistical approaches to assess the robustness of the methodology. A two-group linear discriminant analysis method using a total of 9 time points (which equates to 9 biomarkers) correctly assigned 24/24 (100%) of cancer cases and 70/74 (94.6%) controls. Under leave-one-out cross-validation 23/24 (95.8%) of cancer cases were correctly predicted with 69/74 (93.2%) of controls. For partial least squares discriminant analysis, the correct leave-one-out cross-validation prediction values were 95.8% (cancer cases) and 94.6% (controls). These data are an improvement on those reported by other groups studying headspace gases and also superior to current clinical techniques. This new device shows potential for the diagnosis of bladder cancer, but the data must be reproduced in a larger study. PMID:23861976

  10. Simple force feedback for small virtual environments

    1998-08-01

    In today's civil flight training simulators only the cockpit and all its interaction devices exist as physical mockups. All other elements such as flight behavior, motion, sound, and the visual system are virtual. As an extension to this approach `Virtual Flight Simulation' tries to subsidize the cockpit mockup by a 3D computer generated image. The complete cockpit including the exterior view is displayed on a Head Mounted Display (HMD), a BOOM, or a Cave Animated Virtual Environment. In most applications a dataglove or virtual pointers are used as input devices. A basic problem of such a Virtual Cockpit simulation is missing force feedback. A pilot cannot touch and feel buttons, knobs, dials, etc. he tries to manipulate. As a result, it is very difficult to generate realistic inputs into VC systems. `Seating Bucks' are used in automotive industry to overcome the problem of missing force feedback. Only a seat, steering wheel, pedal, stick shift, and radio panel are physically available. All other geometry is virtual and therefore untouchable but visible in the output device. In extension to this concept a `Seating Buck' for commercial transport aircraft cockpits was developed. Pilot seat, side stick, pedals, thrust-levers, and flaps lever are physically available. All other panels are simulated by simple flat plastic panels. They are located at the same location as their real counterparts only lacking the real input devices. A pilot sees the entire photorealistic cockpit in a HMD as 3D geometry but can only touch the physical parts and plastic panels. In order to determine task performance with the developed Seating Buck, a test series was conducted. Users press buttons, adapt dials, and turn knobs. In a first test, a complete virtual environment was used. The second setting had a plastic panel replacing all input devices. Finally, as cross reference the participants had to repeat the test with a complete physical mockup of the input devices. All panels and physical devices can be easily relocated to simulate a different type of cockpit. Maximal 30 minutes are needed for a complete adaptation. So far, an Airbus A340 and a generic cockpit are supported.

    The benefits and harms of continuous antibiotic prophylaxis (CAP) versus observation in patients with antenatal hydronephrosis (ANH) are controversial. The aim was to determine the effectiveness of CAP for ANH, and if beneficial to determine the best type and regimen of antibiotic and the most harmful to provide guidance for clinical practice. A systematic literature search was performed in databases including Medline, Embase, and Cochrane in June 2015. The protocol was prospectively registered to PROSPERO (CRD42015024775). The search started from 1980, when maternal ultrasound was first introduced into clinical practice. Eligible studies were critically evaluated for risk of bias using Revman software. The outcomes included reduction in urinary tract infections (UTI), drug-related adverse events and kidney functions. Of 797 articles identified, 57 full text articles and six abstracts were eligible for inclusion (2 randomized controlled trials, 11 non-randomized comparative studies, and 50 case series). It remains unclear whether CAP is superior to observation in decreasing UTIs. No conclusion could be drawn for drug-related adverse events and kidney function because of lack of data. Children who were not circumcised, with ureteral dilatation, and high-grade hydronephrosis may be more likely to develop UTI, and CAP may be warranted for these subgroups of patients. A majority of the studies had low-to-moderate quality of evidence and with high risk of bias. The benefits of CAP in a heterogeneous group of children with ANH involving different etiologies remains unproven. However, the evidence in the form of prospective and retrospective observational studies has shown that it reduces febrile UTI in particular subgroups.

    Contemporary medical robotic systems used in urologic surgery usually consist of a computer and a mechanical device to carry out the designated task with an image acquisition module. These systems are typically from one of the two categories: offline or online robots. Offline robots, also known as fixed path robots, are completely automated with pre-programmed motion planning based on pre-operative imaging studies where precise movements within set confines are carried out. Online robotic systems rely on continuous input from the surgeons and change their movements and actions according to the input in real time. This class of robots is further divided into endoscopic manipulators and master-slave robotic systems. Current robotic surgical systems have resulted in a paradigm shift in the minimally invasive approach to complex laparoscopic urological procedures. Future developments will focus on refining haptic feedback, system miniaturization and improved augmented reality and telesurgical capabilities.

    Complications related to inflatable penile prosthesis (IPP) and artificial urinary sphincter (AUS) reservoirs are rare, potentially life threatening, and poorly described in the literature. As more devices are implanted, the incidence of reservoir-related complications may increase, and it will be important to recognize the relevant signs and symptoms. We present a case series of reservoir-related complications presenting to our institution for treatment. We also reviewed all accounts of reservoir-related complications within the urologic literature. Three cases of reservoir-related complications are presented. Case 1 involves erosion of an intact AUS reservoir into the cecum of a patient with a history of myelomeningocele and bladder augmentation. Case 2 involves an IPP reservoir causing vascular compression, resulting in open exploration and repositioning of the reservoir. Case 3 involves intraperitoneal migration of a retained IPP reservoir to a subhepatic area, which was then removed laparoscopically. Literature review yielded descriptions of eight cases of intestinal complications, five cases of vascular complications, but zero reports of migration to a subhepatic area. Other notable complications include 20 reported cases of reservoir erosion into the bladder and inguinal herniation of the reservoir. Complications involving urologic prosthesis reservoirs, although rare, can have serious implications for patients. A high index of suspicion and familiarity with treatment options is required in order to allow timely diagnosis and appropriate treatment. Patients with prior major abdominal surgeries seem to be more prone to intestinal complications of reservoirs and warrant special concern. Cui T, Terlecki R, and Mirzazadeh M.

    To collate world reports of adverse events (AEs) resulting from lasers used in urology. The Manufacturer and User Facility Device Experience (MAUDE) database of the United States Food and Drug Administration (FDA) was searched using the term "Laser for gastro-urology use." In addition, the Rockwell Laser Industries (RLI) Laser Accident Database was searched for the following types of lasers: neodymium-doped yttrium aluminum garnet (Nd:YAG), holmium:yttrium aluminum garnet (Ho:YAG), potassium titanyl phosphate (KTP), diode and thulium:YAG (Tm:YAG). Both databases were last accessed on October 1, 2012. Overall, there were 433 AEs; 166 in MAUDE database (1992-2012) and 267 in RLI database (1964-2005). Most of the AEs (198/433 or 46%) resulted from generator failure or fiber tip breaking. Whereas there were 20 (4.6%) AEs harming medical operators, there were 159 (37%) AEs harming nonmedical operators using Nd:YAG, KTP, and diode lasers. Eye injuries ranging from mild corneal abrasions to total vision loss were reported in 164 AEs with the use of Nd:YAG, KTP, and diode lasers. Overall, there were 36 (8.3%) AEs resulting in patient harm, including 7 (1.6%) mortalities, 3 deaths from ureteral perforation using the Ho:YAG laser, and 4 deaths from air emboli using the Nd:YAG laser. Other reported patient injuries included bladder perforation resulting in urinary diversion in a patient, in addition to minor skin burns, internal burns, and bleeding in others. There were no AEs reported with the use of Tm:YAG laser. Most of the AEs reported relate to equipment failure. There were no eye injuries reported with the use of Ho:YAG lasers. Caution must be exercised when using lasers in urology, including wearing appropriate eye protection when using Nd:YAG, KTP, and diode lasers.

    The objective is to provide a review of nocturnal enuresis (NE), including its epidemiology, etiology, pathophysiology, evaluation, and current management. We also set to provide further insight on the treatment of this condition from the experience derived from patients cared for at our tertiary-care institution. NE affects approximately 15% of all children at 5-year-old, affecting boys more frequently than girls. At our large university tertiary pediatric urology center, NE and incontinence, in general, is one the most common chief complaints prompting urologic care. In this review, we examine the condition in detail, highlighting specific goals of the initial evaluation and treatment. We contrast the commonly implemented treatment recommendations, available from the literature with strategies we have found valuable from our extensive experience in treating patients with this disorder. Using current urologic reference textbooks, book chapters, Medline, journal articles and reviews describing the many aspects of NE were reviewed in order to describe NE and the current practices at our institution. Although, this is not a systematic literature review, it includes relevant available research, institutional experience and urological expert opinion and current practices at a tertiary state health facility. The treatment of NE remains a challenge for many pediatricians and pediatric urologists. This likely stems from the multiple possible etiologies of the disorder. We have established a treatment algorithm at our institution, which we have found successful in the majority of our patients. This consists of starting patients on urotherapy, then offering both the enuresis alarm device and medication therapy as first line treatments, and finally adding anticholingerics for combination therapy. Our hope is with further research the treatment of NE will continue to improve. PMID:25506580

  18. A review of sensing technologies for small and large-scale touch panels

    Akhtar, Humza; Kemao, Qian; Kakarala, Ramakrishna

    2017-06-01

    A touch panel is an input device for human computer interaction. It consists of a network of sensors, a sampling circuit and a micro controller for detecting and locating a touch input. Touch input can come from either finger or stylus depending upon the type of touch technology. These touch panels provide an intuitive and collaborative workspace so that people can perform various tasks with the use of their fingers instead of traditional input devices like keyboard and mouse. Touch sensing technology is not new. At the time of this writing, various technologies are available in the market and this paper reviews the most common ones. We review traditional designs and sensing algorithms for touch technology. We also observe that due to its various strengths, capacitive touch will dominate the large-scale touch panel industry in years to come. In the end, we discuss the motivation for doing academic research on large-scale panels.

    During recent years color reproduction systems for consumer needs have experienced various difficulties. In particular, flat panels and printers could not reach a satisfactory color match. The RGB image stored on an Internet server of a retailer did not show the desired colors on a consumer display device or printer device. STMicroelectronics addresses this important color reproduction issue inside their advanced display engines using novel algorithms targeted for low cost consumer flat panels. Using a new and genuine RGB color space transformation, which combines a gamma correction Look-Up-Table, tetrahedrization, and linear interpolation, we satisfy market demands.

    The investigation and description of psychosomatic interrelationships has a long tradition in the field of urology. At the beginning of last century, psychosomatic theories and therapies involving urologic questions were developed, some of which are still part of current therapeutic strategies. Numerous studies accentuated the need for a psychosomatic diagnostics and therapy of urologic diseases. The appreciation of psychosomatic urology is growing, a fact which is reflected in current urological teaching curricula.

    High-risk medical devices often undergo modifications, which are approved by the US Food and Drug Administration (FDA) through various kinds of premarket approval (PMA) supplements. There have been multiple high-profile recalls of devices approved as PMA supplements. To characterize the quality of the clinical studies and data (strength of evidence) used to support FDA approval of panel-track supplements (a type of PMA supplement pathway that is used for significant changes in a device or indication for use and always requires clinical data). Descriptive study of clinical studies supporting panel-track supplements approved by the FDA between April 19, 2006, and October 9, 2015. Panel-track supplement approval. Methodological quality of studies including randomization, blinding, type of controls, clinical vs surrogate primary end points, use of post hoc analyses, and reporting of age and sex. Eighty-three clinical studies supported the approval of 78 panel-track supplements, with 71 panel-track supplements (91%) supported by a single study. Of the 83 studies, 37 (45%) were randomized clinical trials and 25 (30%) were blinded. The median number of patients per study was 185 (interquartile range, 75-305), and the median follow-up duration was 180 days (interquartile range, 84-270 days). There were a total of 150 primary end points (mean [SD], 1.8 [1.2] per study), and 57 primary end points (38%) were compared with controls. Of primary end points with controls, 6 (11%) were retrospective controls and 51 (89%) were active controls. One hundred twenty-one primary end points (81%) were surrogate end points. Thirty-three studies (40%) did not report age and 25 (30%) did not report sex for all enrolled patients. The FDA required postapproval studies for 29 of 78 (37%) panel-track supplements. Among clinical studies used to support FDA approval of high-risk medical device modifications, fewer than half were randomized, blinded, or controlled, and most primary outcomes were based on surrogate end points. These findings suggest that the quality of studies and data evaluated to support approval by the FDA of modifications of high-risk devices should be improved.

    To assess the feasibility, safety and usefulness of augmented reality-assisted urological surgery using smartglass (SG). Seven urological surgeons (3 board urologists and 4 urology residents) performed augmented reality-assisted urological surgery using SG for 10 different types of operations and a total of 31 urological operations. Feasibility was assessed using technical metadata (number of photographs taken/number of videos recorded/video time recorded) and structured interviews with the urologists on their use of SG. Safety was evaluated by recording complications and grading according to the Clavien-Dindo classification. Usefulness of SG for urological surgery was queried in structured interviews and in a survey. The implementation of SG use during urological surgery was feasible with no intrinsic (technical defect) or extrinsic (inability to control the SG function) obstacles being observed. SG use was safe as no grade 3-5 complications occurred for the series of 31 urological surgeries of different complexities. Technical applications of SG included taking photographs/recording videos for teaching and documentation, hands-free teleconsultation, reviewing patients' medical records and images and searching the internet for health information. Overall usefulness of SG for urological surgery was rated as very high by 43 % and high by 29 % of surgeons. Augmented reality-assisted urological surgery using SG is both feasible and safe and also provides several useful functions for urological surgeons. Further developments and investigations are required in the near future to harvest the great potential of this exciting technology for urological surgery.

    A sustained and effective oropharyngeal sealing with supraglottic airway is required to maintain the ventilation during laparoscopic surgery. Previous studies have observed the Oropharyngeal Seal Pressure (OSP) for Proseal Laryngeal Mask Airway (PLMA) after pneumoperitoneum in supine and trendelenburg position, where PLMA was found to be an effective airway device. This study was conducted with ProSeal LMA, for laparoscopic Urologic procedures done in lateral position. To measure OSP in supine and lateral position and to observe the effect of pneumoperitoneum in lateral position on OSP. Secondary objectives were to assess adequacy of ventilation and incidence of adverse events. A total number of 25 patients of American Society of Anaesthesiologists (ASA) physical status II and I were enrolled. After induction of anaesthesia using a standardized protocol, PLMA was inserted. Ryle's tube was inserted through drain tube. The position of PLMA was confirmed with ease of insertion of Ryle's tube and fibreoptic grading of vocal cords. Patients were then put in lateral position. The OSP was measured in supine position. This value was baseline comparison for OSP in lateral position and that after pneumoperitoneum. We assessed the efficacy of PLMA for ventilation, after carboperitoneum in lateral position (peak airway pressure, End Tidal Carbon dioxide (EtCO 2 ), SPO 2 ). Incidence of adverse effects (displacement of device, gastric insufflation, regurgitation, coughing, sore throat, blood on device, trauma) was also noted. The OSP was above Peak Airway Pressure (PAP) in supine (22.1±5.4 and 15.4±4.49cm of H 2 O) and lateral position (22.6±5.3 and 16.1±4.6). After pneumoperitoneum, which was in lateral position, there was statistically significant (p-value <0.05) increase in both PAP (19.96±4.015) and OSP (24.32±4.98, p-value 0.03). There was no intraoperative displacement of PLMA. There was no event of suboptimal oxygenation. EtCO 2 was always within normal limits. Gastric insufflation was present in one patient. One patient had coughing and blood was detected on device. Three patients had throat discomfort post-operatively. In this study, Oropharyngeal seal pressures with PLMA were found to increase after pneumoperitoneum in lateral position. PLMA forms an effective seal around airway and is an efficient and safe alternative for airway management in urological laparoscopic surgeries done in lateral position.

    Urology is at the forefront of minimally invasive surgery to a great extent. These procedures produce additional learning challenges and possess a steep initial learning curve. Training and assessment methods in surgical specialties such as urology are known to lack clear structure and often rely on differing operative flow experienced by individuals and institutions. This article aims to assess current urology training modalities, to identify the role of simulation within urology, to define and identify the learning curves for various urologic procedures, and to discuss ways to decrease complications in the context of training. A narrative review of the literature was conducted through December 2015 using the PubMed/Medline, Embase, and Cochrane Library databases. Evidence of the validity of training methods in urology includes observation of a procedure, mentorship and fellowship, e-learning, and simulation-based training. Learning curves for various urologic procedures have been recommended based on the available literature. The importance of structured training pathways is highlighted, with integration of modular training to ensure patient safety. Valid training pathways are available in urology. The aim in urology training should be to combine all of the available evidence to produce procedure-specific curricula that utilise the vast array of training methods available to ensure that we continue to improve patient outcomes and reduce complications. The current evidence for different training methods available in urology, including simulation-based training, was reviewed, and the learning curves for various urologic procedures were critically analysed. Based on the evidence, future pathways for urology curricula have been suggested to ensure that patient safety is improved. Copyright © 2016 European Association of Urology.

    Cancer survivorship focuses largely on improving quality of life. We aimed to determine the rate of ventral incisional hernia (VIH) formation after cancer resection, with implications for survivorship. Patients without prior VIH who underwent abdominal malignancy resections at a tertiary center were followed up to 2 years. Patients with a viewable preoperative computed tomography (CT) scan and CT within 2 years postoperatively were included. Primary outcome was postoperative VIH on CT, reviewed by a panel of surgeons uninvolved with the original operation. Factors associated with VIH were determined using Cox proportional hazards regression. 1847 CTs were reviewed among 491 patients (59 % men), with inter-rater reliability 0.85 for the panel. Mean age was 60 ± 12 years; mean follow-up time 13 ± 8 months. VIH occurred in 41 % and differed across diagnoses: urologic/gynecologic (30 %), colorectal (53 %), and all others (56 %) (p < 0.001). Factors associated with VIH (adjusting for stage, age, adjuvant therapy, smoking, and steroid use) included: incision location [flank (ref), midline, hazard ratio (HR) 6.89 (95 %CI 2.43-19.57); periumbilical, HR 6.24 (95 %CI 1.84-21.22); subcostal, HR 4.55 (95 %CI 1.51-13.70)], cancer type [urologic/gynecologic (ref), other {gastrointestinal, pancreatic, hepatobiliary, retroperitoneal, and others} HR 1.86 (95 %CI 1.26-2.73)], laparoscopic-assisted operation [laparoscopic (ref), HR 2.68 (95 %CI 1.44-4.98)], surgical site infection [HR 1.60 (95 %CI 1.08-2.37)], and body mass index [HR 1.06 (95 %CI 1.03-1.08)]. The rate of VIH after abdominal cancer operations is high. VIH may impact cancer survivorship with pain and need for additional operations. Further studies assessing the impact on QOL and prevention efforts are needed.

    We aimed to clarify the scope of pediatric urological procedures that Canadian urology residents are perceived to be competent to perform upon graduation. We conducted a survey from April 2005 to June 2006 of urology residency program directors (UPDs), senior urology residents (SURs) and Pediatric Urologists of Canada (PUC) members from all 12 Canadian training programs. Questions focused on which of 23 pediatric urological procedures the 3 study groups perceived urology residents would be competent to perform upon completion of residency without further fellowship training. Procedures were based on the "A," "B" and "C" lists of procedures (least complex to most complex) as outlined in the Royal College of Physicians and Surgeons of Canada Objectives of Training in Urology. Response rates were 12/12 (100%), 41/53 (77%) and 17/23 (74%) for UPDs, SURs and PUC members, respectively. Average exposure to pediatric urology during residency was 5.4 (range 3-9) months and considered sufficient by 75% of UPDs and 69% of SURs, but only 41% of PUC members (p = 0.05). Overall, the 3 groups disagreed on the level of competence for performing level "A" and "B" procedures, with significant disagreement between PUC members and UPDs as well as SURs (p < 0.005). PUC members perceive Canadian urology residents' exposure to pediatric urology as insufficient and their competence for procedures of low to moderate complexity as inadequate. Further investigation regarding exposure to and competence in other emerging subspecialty spheres of urology may be warranted. Ongoing assessment of the objectives for training in pediatric urology is required.

    Introduction Urology continues to be a highly desirable specialty, despite decreasing exposure of students to Urology in U.S. medical schools. In this study, we set out to assess how U.S. medical schools compare to one another with regard to the number of students that each sends into Urological training and to evaluate the reasons why some medical schools consistently send more students into urology than others. Materials and Methods The authors obtained AUA Match data for the 5 Match seasons from 2005–2009. A survey of all successful participants was then performed. The survey instrument was designed to determine what aspects of the medical school experience influenced students to choose to specialize in Urology. A bivariate and multivariate analysis was then performed to assess which factors correlated with more students entering Urology from a particular medical school. Results Between 2005 and 2009, 1,149 medical students from 130 medical schools successfully participated in the Urology match. Of the 132 allopathic medical schools, 128 sent at least 1 student into Urology (mean 8.9, median 8, SD 6.5). A handful of medical schools were remarkable outliers, sending significantly more students into Urology than other institutions. Multivariate analysis revealed that a number of medical-school related variables including strong mentorship, medical school ranking, and medical school size correlated with more medical students entering Urology. Conclusion Some medical schools launch more Urologic careers than others. Although reasons for these findings are multifactorial, recruitment of Urologic talent pivots on these realities.

    The functioning of modern urological departments and the high level of service they provide is possible through, among other things, the use of modern laser techniques. Open operations have been replaced by minimally invasive procedures, and classical surgical tools by advanced lasers. The search for new applications with lasers began as technology developed. Among many devices available, holmium, diode and thulium lasers are currently the most popular. Depending on the wavelength, the absorption by water and hemoglobin and the depth of penetration, lasers can be used for coagulation, vaporization and enucleation. In many centres, after all the possibilities of pharmacological treatment have been exhausted, lasers are used as the primary treatment for patients with benign prostatic hyperplasia, with therapeutic results that are better than those obtained through open or endoscopic operations. The use of lasers in the treatment of urolithiasis, urinary strictures and bladder tumours has made treatment of older patients with multiple comorbidities safe, without further necessity to modify the anticoagulant drug treatment. Laser procedures are additionally less invasive, reduce hospitalization time and enable a shorter bladder catheterization time, sometimes even eliminating the need for bladder catherterization completely. Such procedures are also characterized by more stable outcomes and a lower number of reoperations. There are also indications that with the increased competition among laser manufacturers, decreased purchase and maintenance costs, and increased operational safety, laser equipment will become mandatory and indispensable asset in all urology wards.

    This work proposes a control device for autonomous solar tracker based on one axis, It consists of two main parts; the control part which is based on "the PIC16f628a"; it has the role of controlling, measuring and plotting responses. The second part is a mechanical device, which has the role of making the solar panel follows the day-night change of the sun throughout the year. Both parties are established to improve energy generation of the photovoltaic panels. In this paper, we will explain the main operating principles of our system. Also, we will provide experimental results which demonstrate the good performance and the efficiency of this system. This innovation is different from what has been proposed in previous studies. The important points of this system are maximum output energy and minimum energy consumption of solar tracker, its cost is relatively low with simplicity in implementation. The average power increase produced by using the tracking system for a particular day, is over 30 % compared with the static panel.

    An explosion suppression system and triggering apparatus therefor are provided for quenching gas and dust explosions. An electrically actuated suppression mechanism which dispenses an extinguishing agent into the path ahead of the propagating flame is actuated by a triggering device which is light powered. This triggering device is located upstream of the propagating flame and converts light from the flame to an electrical actuation signal. A pressure arming device electrically connects the triggering device to the suppression device only when the explosion is sensed by a further characteristic thereof beside the flame such as the pioneer pressure wave. The light powered triggering device includes a solar panel which is disposed in the path of the explosion and oriented between horizontally downward and vertical. Testing mechanisms are also preferably provided to test the operation of the solar panel and detonator as well as the pressure arming mechanism.

    A new panel known as the Guns and High Gas Output Panel was organized in 1999 under the auspices of the JANNAF Propellant and Characterization SubCommittee (PDCS). This is an introduction to our first meeting, purpose of the panel, and the scope of activities to be covered. The primary purpose of the panel is very simple: to provide a single focal point for interfacing Government Laboratories (Department of Defense and Department of Energy) and commercial industry researchers to share R&D activities and findings (i.e. facilitate the exchange of information) specifically aimed at gun-launched propulsion and high-gas output devices (gas generators and air bag inflators). Specific areas of interest included in the Panel's scope (and the Technical Data Base) are the following: (1) new propellant formulations and chemistry, (2) new ingredients, (3) ballistic effects of the new formulations and ingredients, (4) new processing methods unique to gun propellants, (5) thermochemistry of new ingredients, (6) unique physical and mechanical properties, (7) burning rates of new propellants and small scale closed bomb testing, (8) plasma effects on the propellant, and (9) unique safety and insensitive munitions properties.

    Use of electronic cigarettes (ECs) is on the rise in most high-income countries. Smoking conventional cigarettes is a known risk factor for urologic malignancy incidence, progression, and mortality, as well as for other urologic health indicators. The potential impact of EC use on urologic health is therefore of clinical interest to the urology community. To review the available data on current EC use, including potential benefits in urologic patients, potential issues linked to toxicology of EC constituents, and how this might translate into urologic health risks. A Medline search was carried out in August 2016 for studies reporting urologic health outcomes and EC use. Snowballing techniques were also used to identify relevant studies from recent systematic reviews. A narrative synthesis of data around EC health outcomes, toxicology, and potential use in smoking cessation and health policy was carried out. We found no studies to date that have been specifically designed to prospectively assess urologic health risks, even in an observational setting. Generating such data would be an important contribution to the debate on the role of ECs in public health and clinical practice. There is evidence from a recent Cochrane review of RCTs that ECs can support smoking cessation. There are emerging data indicating that potentially harmful components of ECs such as tobacco-specific nitrosamines, polyaromatic hydrocarbons, and heavy metals could be linked to possible urologic health risks. ECs might be a useful tool to encourage cessation of conventional cigarette smoking. However, data collection around the specific impact of ECs on urologic health is needed to clarify the possible patient benefits, outcomes, and adverse events. While electronic cigarettes might help some people to stop smoking, their overall impact on urologic health is not clear. Copyright © 2017 European Association of Urology. All rights reserved.

    Implementing a robotic urological surgery program requires institutional support, and necessitates a comprehensive, detail-oriented plan that accounts for training, oversight, cost and case volume. Given the prevalence of robotic surgery in adult urology, in many instances it might be feasible to implement a pediatric robotic urology program within the greater context of adult urology. This involves, from an institutional standpoint, proportional distribution of equipment cost and operating room time. However, the pediatric urology team primarily determines goals for volume expansion, operative case selection, resident training and surgical innovation within the specialty. In addition to the clinical model, a robust economic model that includes marketing must be present. This review specifically highlights these factors in relationship to establishing and maintaining a pediatric robotic urology program. In addition, we share our data involving robot use over the program's first nine years (December 2007-December 2016). © 2017 The Japanese Urological Association.

    Despite efforts to standardize histopathology practice through the development of guidelines, the interpretation of morphology is still hampered by subjectivity. We here describe Pathology Imagebase, a novel mechanism for establishing an international standard for the interpretation of pathology specimens. The International Society of Urological Pathology (ISUP) established a reference image database through the input of experts in the field. Three panels were formed, one each for prostate, urinary bladder and renal pathology, consisting of 24 international experts. Each of the panel members uploaded microphotographs of cases into a non-public database. The remaining 23 experts were asked to vote from a multiple-choice menu. Prior to and while voting, panel members were unable to access the results of voting by the other experts. When a consensus level of at least two-thirds or 16 votes was reached, cases were automatically transferred to the main database. Consensus was reached in a total of 287 cases across five projects on the grading of prostate, bladder and renal cancer and the classification of renal tumours and flat lesions of the bladder. The full database is available to all ISUP members at www.isupweb.org. Non-members may access a selected number of cases. It is anticipated that the database will assist pathologists in calibrating their grading, and will also promote consistency in the diagnosis of difficult cases. © 2017 John Wiley & Sons Ltd.

    The European Association of Urology (EAU) guidelines on urinary incontinence published in March 2012 have been rewritten based on an independent systematic review carried out by the EAU guidelines panel using a sustainable methodology. We present a short version here of the full guidelines on the surgical treatment of patients with urinary incontinence, with the aim of dissemination to a wider audience. Evidence appraisal included a pragmatic review of existing systematic reviews and independent new literature searches based on Population, Intervention, Comparator, Outcome (PICO) questions. The appraisal of papers was carried out by an international panel of experts, who also collaborated in a series of consensus discussions, to develop concise structured evidence summaries and action-based recommendations using a modified Oxford system. The full version of the guidance is available online (www.uroweb.org/guidelines/online-guidelines/). The guidance includes algorithms that refer the reader back to the supporting evidence and have greater accessibility in daily clinical practice. Two original meta-analyses were carried out specifically for these guidelines and are included in this report. These new guidelines present an up-to-date summary of the available evidence, together with clear clinical algorithms and action-based recommendations based on the best available evidence. Where high-level evidence is lacking, they present a consensus of expert panel opinion. Copyright © 2012 AEU. Published by Elsevier Espana. All rights reserved.

    In this paper we discuss the modeling of three basic kinds of 3-D manipulations in the context of a logical hand device and our virtual panel architecture. The logical hand device is a useful software abstraction representing hands in virtual environments. The virtual panel architecture is the 3-D component of the 2-D window systems. Both of the abstractions are intended to form the foundation for adaptable 3-D manipulation.

    In the urology clinics there is an important volume of limited-complexity pathology that consumes an important part of resources. Delegating some tasks of this type to Nurses may imply a competitive advantage in economic terms without decrease in the quality of the care given to patients and their level of satisfaction. This is an example of the concept of inverse innovation. In this work we try to make public our experience in the management by nursing staff of features of the urology consultation traditionally reserved to physicians, as well as the design of the related processes. We developed the most frequent processes competence of the nursing staff in the unit: 1) Care of ambulatory urological surgery pathology; 2) Urologic ultrasound; 3) Traditional urologic nurse consultation. During 2013 the nursing staff performed 423 ambulatory urologic surgery pathology clinic visits, 931 urologic ultrasounds and 1019 varied actions corresponding to traditional urological nurse work.We developed stabilization formularies and flow diagrams of the aforementioned processes. We performed a quantification of the amount of money saved in comparison with the costs generated if a nurse or a physician was employed. Such saving was 2,78 and 4,00 Euros in the ambulatory urological surgery pathology and urologic ultrasound, respectively. Total savings in both processes was 4900 Euros. Implication of urological nursing staff in certain care tasks traditionally reserved to the physician is possible without increase in quality defects, obtaining an advantage in terms of economic cost and flexibility in staff organization thanks to the expansion of the competence array.

    Surgery has a rich and colourful history dating as far back as, at least, the Neolithic period. There have been many advances in knowledge and technology, as well as changes to working conditions and public perception and expectations. The urology training programme is jointly managed by the Royal Australasian College of Surgeons and the Urological Society of Australia and New Zealand. Urological training in Australia and New Zealand has undergone a number of changes over the years. A PubMed search was performed to find articles related to surgical training and, more specifically, urological training in Australia and New Zealand. The search terms that were used included 'urology training', 'surgical training', 'Australian urology history' and 'New Zealand urology history'. This narrative review outlines the origin and history of this training programme and describes the changes that have led to the current model of urology training. It also relates some of the current and future challenges faced as the training programme continues to evolve in order to improve its ability to train future urologists to meet the needs of the community and to ensure public safety. The urological training programme has evolved a number of times in order to tackle the challenges presented by evolving technology, community expectation and the needs of the trainee. © 2017 Royal Australasian College of Surgeons.

  13. Technical advances of interventional fluoroscopy and flat panel image receptor.

    PubMed

    Lin, Pei-Jan Paul

    2008-11-01

    In the past decade, various radiation reducing devices and control circuits have been implemented on fluoroscopic imaging equipment. Because of the potential for lengthy fluoroscopic procedures in interventional cardiovascular angiography, these devices and control circuits have been developed for the cardiac catheterization laboratories and interventional angiography suites. Additionally, fluoroscopic systems equipped with image intensifiers have benefited from technological advances in x-ray tube, x-ray generator, and spectral shaping filter technologies. The high heat capacity x-ray tube, the medium frequency inverter generator with high performance switching capability, and the patient dose reduction spectral shaping filter had already been implemented on the image intensified fluoroscopy systems. These three underlying technologies together with the automatic dose rate and image quality (ADRIQ) control logic allow patients undergoing cardiovascular angiography procedures to benefit from "lower patient dose" with "high image quality." While photoconductor (or phosphor plate) x-ray detectors and signal capture thin film transistor (TFT) and charge coupled device (CCD) arrays are analog in nature, the advent of the flat panel image receptor allowed for fluoroscopy procedures to become more streamlined. With the analog-to-digital converter built into the data lines, the flat panel image receptor appears to become a digital device. While the transition from image intensified fluoroscopy systems to flat panel image receptor fluoroscopy systems is part of the on-going "digitization of imaging," the value of a flat panel image receptor may have to be evaluated with respect to patient dose, image quality, and clinical application capabilities. The advantage of flat panel image receptors has yet to be fully explored. For instance, the flat panel image receptor has its disadvantages as compared to the image intensifiers; the cost of the equipment is probably the most obvious. On the other hand, due to its wide dynamic range and linearity, lowering of patient dose beyond current practice could be achieved through the calibration process of the flat panel input dose rate being set to, for example, one half or less of current values. In this article various radiation saving devices and control circuits are briefly described. This includes various types of fluoroscopic systems designed to strive for reduction of patient exposure with the application of spectral shaping filters. The main thrust is to understand the ADRIQ control logic, through equipment testing, as it relates to clinical applications, and to show how this ADRIQ control logic "ties" those three technological advancements together to provide low radiation dose to the patient with high quality fluoroscopic images. Finally, rotational angiography with computed tomography (CT) and three dimensional (3-D) images utilizing flat panel technology will be reviewed as they pertain to diagnostic imaging in cardiovascular disease.

    A light-emitting ceramic based panel, hereafter termed "electroceramescent" panel, is herein claimed. The electroceramescent panel is formed on a substrate providing mechanical support as well as serving as the base electrode for the device. One or more semiconductive ceramic layers directly overlay the substrate, and electrical conductivity and ionic diffusion are controlled. Light emitting regions overlay the semiconductive ceramic layers, and said regions consist sequentially of a layer of a ceramic insulation layer and an electroluminescent layer, comprised of doped phosphors or the equivalent. One or more conductive top electrode layers having optically transmissive areas overlay the light emitting regions, and a multi-layered top barrier cover comprising one or more optically transmissive non-combustible insulation layers overlay said top electrode regions.

    Health services research (HSR) is increasingly important given the focus on patient-centered, cost-effective, high-quality health care. We examine how HSR affects contemporary evidence-based urologic practice and its role in shaping future urologic research and care. PubMed, urologic texts, and lay literature were reviewed for terms pertaining to HSR/outcomes research and urologic disease processes. HSR is a broad discipline that focuses on access, cost, and outcomes of Health care. Its use has been applied to a myriad of urologic conditions to identify deficiencies in access, to evaluate cost-effectiveness of therapies, and to evaluate structural, process, and outcome quality measures. HSR utilizes an evidence-based approach to identify the most effective ways to organize/manage, finance, and deliver high-quality urologic care and to tailor care optimized to individuals.

    The apparatus would include a solar photovoltaic panel mounted on the roof and a panellike assembly mounted in a window opening. The window-mounted assembly would include a stack of thermoelectric devices sandwiched between two heat sinks. A fan would circulate interior air over one heat sink. Another fan would circulate exterior air over the other heat sink. The fans and the thermoelectric devices would be powered by the solar photovoltaic panel. By means of a double-pole, double-throw switch, the panel voltage fed to the thermoelectric stack would be set to the desired polarity: For cooling operation, the chosen polarity would be one in which the thermoelectric devices transport heat from the inside heat sink to the outside one; for heating operation, the opposite polarity would be chosen. Because thermoelectric devices are more efficient in heating than in cooling, this apparatus would be more effective as a heater than as a cooler. However, if the apparatus were to include means to circulate air between the outside and the inside without opening the windows, then its effectiveness as a cooler in a hot, sunny location would be increased.

    Smartphones are increasingly playing a role in healthcare and previous studies assessing medical applications (apps) have raised concerns about lack of expert involvement and low content accuracy. However, there are no such studies in Urology. We reviewed Urology apps with the aim of assessing the level of participation of healthcare professionals (HCP) and scientific Urology associations in their development. A systematic search was performed on PubMed, Apple's App Store and Google's Play Store, for Urology apps, available in English. Apps were reviewed by three graders to determine the app's platform, target customer, developer, app type, app category, price and the participation of a HCP or a scientific Urology association in the development. The search yielded 372 apps, of which 150 were specific for Urology. A fifth of all apps had no HCP involvement (20.7%) and only a third had been developed with a scientific Urology association (34.7%). The lowest percentage of HCP (13.4%) and urological association (1.9%) involvement was in apps designed for the general population. Furthermore, there was no contribution from an Urology society in "Electronic Medical Record" nor in "Patient Information" apps. A limitation of the study is that only Android and iOS apps were reviewed. Despite the increasing Mobile Health (mHealth) market, this is the first study that demonstrates the lack of expert participation in the design of Urology apps, particularly in apps designed for the general public. Until clear regulation is enforced, the urological community should help regulate app development. Maintaining a register of certified apps or issuing an official scientific seal of approval could improve overall app quality. We propose that urologists become stakeholders in mHealth, shaping future app design and promoting peer-review app validation.

    To analyse the value of an urology initiation session proposed to young interns to improve recruitment of the discipline since the introduction of the new National-Ranking Exam (NRE). In October 2004, the 77 interns appointed to surgery in Paris on the basis of the ENC participated in a one-day urology initiation session organized by the AFUF, at the AP-HP School of Surgery. All interns were given a questionnaire at the beginning of the session to record the following data: age, gender, teaching hospital, a student attachment in urology and desired specialization as a function of the surgical training programmes proposed by the ENC. Items concerning the desired specialization were resubmitted to the interns at the end of the session. Population. 77 interns, 48 females (62.3%) and 29 males (37.7%) with a mean age of 25.2 +/- 5 years (range: 23-31). 55 interns had trained at a Parisian teaching hospital (67%) and 22 (28.6%) had trained at a provincial teaching hospital. 16 interns (20.8%) had completed at least one urology attachment during their medical training. Desired specialization. Orthopaedics was the discipline most frequently cited (n = 20; 26%). Urology was chosen by 8 interns (10.40%), who had all completed an urology attachment during their medical training. At the end of the urology initiation session, another 8 interns expressed the desire to specialize in urology. Of the 16 potential urology interns, 9 (56.2%) confirmed that their decision was final. Urology occupies a special place and remains a popular surgical speciality among students. Organization of practical sessions constitutes a solution to inform, create an emulation and motivate surgery interns to choose urology.

    To quantify public and academic interest in the urological field using a novel new media-based methodology. We systematically measured public and academic interest in 56 urological keywords and combined in nine subspecialties. Public interest was quantified as video views on YouTube. Academic interest was quantified as article citations using Microsoft Academic Search. The public-to-academic interest ratio was calculated for a comparison of subspecialties as well as for diseases and treatments. For the selected 56 urological keywords, we found 226 617 591 video views on YouTube and 2 146 287 citations in the academic literature. The public-to-academic interest ratio was highest for the subspecialties robotic urology (ratio 6.3) and andrological urology (ratio 4.6). Prostate cancer was the central urological disease combining both a high public (20% of all video views) and academic interest (26% of all citations, ratio 0.8). Further diseases/treatments of high public interest were premature ejaculation (ratio 54.4), testicular cancer (ratio 11.4), erectile dysfunction (ratio 5.5) and kidney transplant (ratio 3.7). Urological treatments had a higher public-to-academic interest ratio (median ratio 0.25) than diseases (median ratio 0.05; P = 0.029). A quantification of academic and public interest in the urological field is feasible using a novel new media-based methodology. We found several mismatches in public versus academic interest in urological diseases and treatments, which has implications for research strategies, conference planning and patient information projects. Regular re-assessments of the public and academic interest landscape can contribute to detecting and proving trends in the field of urology. © 2018 The Japanese Urological Association.

    Integrated urology-radiation oncology (RO) practices have been advocated as a means to improve community-based prostate cancer care by joining urologic and radiation care in a single-practice environment. However, little is known regarding the scope and actual physical integration of such practices. We sought to characterize the emergence of such practices in Texas, their extent of physical integration, and their potential effect on patient travel times for radiation therapy. A telephone survey identified integrated urology-RO practices, defined as practices owned by urologists that offer RO services. Geographic information software was used to determine the proximity of integrated urology-RO clinic sites with respect to the state's population. We calculated patient travel time and distance from each integrated urology-RO clinic offering urologic services to the RO treatment facility owned by the integrated practice and to the nearest nonintegrated (independent) RO facility. We compared these times and distances using the Wilcoxon-Mann-Whitney test. Of 229 urology practices identified, 12 (5%) offered integrated RO services, and 182 (28%) of 640 Texas urologists worked in such practices. Approximately 53% of the state population resides within 10 miles of an integrated urology-RO clinic site. Patients with a diagnosis of prostate cancer at an integrated urology-RO clinic site travel a mean of 19.7 miles (26.1 min) from the clinic to reach the RO facility owned by the integrated urology-RO practice vs 5.9 miles (9.2 min) to reach the nearest nonintegrated RO facility (P<.001). Integrated urology-RO practices are common in Texas and are generally clustered in urban areas. In most integrated practices, the urology clinics and the integrated RO facilities are not at the same location, and driving times and distances from the clinic to the integrated RO facility exceed those from the clinic to the nearest nonintegrated RO facility.

    2013-01-01

    Urology is perceived as a competitive specialty choice. Declining undergraduate exposure and the preference for "lifestyle specialties" may jeopardize urology's popularity. Our objective was to assess trends in application and matching rates to urology compared with other surgical specialties. We reviewed data collected by Canadian Residency Matching Service (CaRMS) and the Canadian Post-MD Education Registry since expansion in Canadian medical school enrollment began (2002-2011). The following were examined: applicant preference, number of positions, gender patterns, and match results. "Surgery" included general surgery, orthopedics, plastics, ENT, and urology. From 2002 to 2011 CaRMS applicants increased from 1117 to 2528 (126%). The number of applicants selecting surgery first increased from 178 to 338(90%). The number of surgery positions increased from 138 to 275 (100%). Urology positions increased from 15 to 31 (113%). Applicants to urology increased only 40% (30-42). The proportion of all CARMs applicants selecting urology as their first choice decreased from 2.7% (30) to 1.7% (42). The ratio of first choice urology applicants to positions decreased from 2 to 1.35. The probability of matching urology as first choice increased from 50% to 76%. Female medical graduates increased from 51% to 58%. The female applicants selecting surgery first increased from 21% (49) to 41% (173). In contrast, females selecting urology first rose from 13% (4) to 17% (7). Urology in Canada is becoming less competitive. Residency positions have doubled since 2002 whereas the number of applicants remains static. This trend was not reflected in other surgical specialities. Factors accounting for this may include poor undergraduate exposure, demand for specialties with controllable lifestyles, gender shifts in undergraduate medicine, and lack of role models. The need for undergraduate exposure to urology and vetting numbers of residency positions remains a matter of paramount importance. Copyright © 2013 Association of Program Directors in Surgery.

Patients with a diagnosis of prostate cancer at an integrated urology-RO clinic site travel a mean of 19.7 miles (26.1 min) from the clinic to reach the RO facility owned by the integrated urology-RO practice vs 5.9 miles (9.2 min) to reach the nearest nonintegrated RO facility (P<.001). Conclusions: Integrated urology-RO practices are common in Texas and are generally clustered in urban areas. In most integrated practices, the urology clinics and the integrated RO facilities are not at the same location, and driving times and distances from the clinic to the integrated RO facility exceed those from the clinic to the nearest nonintegrated RO facility.« less

    Social media (SoMe) are increasingly being integrated into personal and professional life, with urology being a leading medical specialty in SoMe adoption. We aimed to assess the perceived role of SoMe in urologic knowledge acquisition among young urologists across Europe. Members of the European Society of Residents in Urology designed a 20-item online survey via surveymonkey.com. The survey was designed in accordance with Checklist for Reporting Results of Internet E-Surveys (CHERRIES) guidelines and was distributed via e-mail and social media in 23 European countries to urology residents and young urologists. Statistical Package for the Social Sciences (SPSS) software was used for descriptive statistics and statistical analysis. For comparative analysis the Mann-Whitney U test was used. A total of 316 young urologists with a mean age of 31.2±3.9 yr responded to the survey. Of the respondents, 99% use SoMe in a personal and/or professional way. YouTube and LinkedIn are the most frequently used platforms for professional use. SoMe were ranked in third place as an information source for urologic news/updates, lying behind journals and websites but ahead of congresses and books. Video content from YouTube or other sources was ranked as a preferred tool to see/understand surgical techniques ahead of websites and reference books. 61% follow urologic associations, 47% follow urologic events, 44% follow urologic journals, and 39% follow urologic experts on SoMe. The perceived influence of SoMe on urology knowledge was rated as moderate to high by 63% and as low to none by 37% of young urologists. Of the respondents, 44% apply guidelines on the appropriate use of SoMe in urology. SoMe play a significant role in knowledge acquisition by young urologists in Europe. Physicians, organizations, and institutions should strive to spread and provide valuable educational content through SoMe. Social media can be valuable for education in urology because it is useful to keep abreast of new developments in this field of medicine. Copyright © 2016 European Association of Urology.

    To adapt to Spanish the recommendations for the appropriate use of social media (SoMe) in the urological setting prepared by the European Association of Urology (EAU). The use of SoMe has become fairly popular in the international urological community. Due to the nature of the medical content shared among healthcare professionals through SoMe, however, there is the risk of medical and legal problems. For this reason, various international urological associations such as the American Urological Association, the British Association of Urological Surgeons and EAU have published their recommendations for the appropriate use of social media. Efforts have been made to adapt and summarise the recommendations of the EAU in Spanish and to publish them in Actas Urológicas Españolas (@actasurologicas), the official journal of the Spanish Urological Association (@InfoAEU) and the American Confederation of Urology (@CAU_URO). SoMe include well-known platforms such as Twitter, Facebook and YouTube, which have undoubtedly changed the way in which people communicate and interact. SoMe offer clear advantages for communicating between professionals, working in teams, disseminating knowledge and creating professional profiles and are increasingly used by patients and healthcare practitioners. The introduction of SoMe in the urological community has started a revolution in how scientific articles are shared, how people participate in congresses and how international urological associations communicate with their followers. However, SoMe is generally an open public setting, with potential risks for confidentiality and the doctor-patient relationship due to the nature of the shared information. The present recommendations include tools for creating professional profiles, protecting confidentiality and creating honest and responsible content. SoMe represents a fascinating area for the communication and dissemination of knowledge, with considerable applicability in health care and the urological community. New efforts are being directed to extend the use of social media in the urological community, measuring its actual academic impact and standardising the language employed. Copyright © 2015 AEU.

    A multipurpose panel was developed to provide a flexible control and a LED display panel with easily changeable nomenclature for use in applications where panel space is limited, but where a number of similar subsystems must be controlled, or where basic panel nomenclature and functions must be changed rapidly, as in the case of between mission changes of space shuttle payloads. In the first application, panel area limitations are overcome by time sharing a central control panel among several subsystems. In the latter case, entire control panel changes are effected by simply replacing a memory module, thereby reducing the extent of installation and checkout procedures between missions. Several types of control technologies (other than LED's) which show potential in meeting criteria for overcoming limitations of the panel are assessed.

  10. Analysis of power supply circuits for electroluminescent panels

    2016-12-01

    The electroluminescent panel is a light emitting device that requires for normal operations alternative voltages with peak to peak amplitudes in 100V… 300V range and frequencies in 100Hz … 2 kHz range. Its advantages, when compared with standard light sources like incandescent lamps, gas-discharge lamps or light emitting diodes (LEDs), are lower power consumption, flexible substrate and uniform light without observable luminous points. One disadvantage of electroluminescent panels is the complex power supply required to drive them, but the continuous improvement in passive and active integrated devices for switched mode power supplies will eventually solve this issue. The present paper studies different topologies for these power supplies and the effect of the electric parameters like the amplitude, frequency, waveform of the supplying voltage on the light emission and on power consumption for electroluminescent panels with different size and colors.

    2013-07-01

    The current conceptualization of urological chronic pelvic pain syndrome in men recognizes a wide variety of pain, psychosocial, sexual and urological symptoms and markers that may contribute to decreased quality of life. Unfortunately, this syndrome is difficult to clearly define and treat due to heterogeneous symptom profiles. We systematically describe these heterogeneous symptoms and investigated whether they could be subtyped into distinct syndromes. A total of 171 men diagnosed with urological chronic pelvic pain syndrome completed validated questionnaires, a structured genital pain interview, digital pain threshold testing and urological assessment. Pain interview results are systematically presented as descriptive information. We used k-means cluster analysis to define subtypes. Seven homogenous, distinct clusters were defined, each with a remarkably different symptom presentation. These clusters were described and related to previous hypotheses of urological chronic pelvic pain syndrome etiology. These clusters may represent distinct subtypes of urological chronic pelvic pain syndrome that can be used to guide treatment more effectively. Defining subtypes may also improve our understanding of the underlying mechanisms of urological chronic pelvic pain syndrome.

    To assess the impact of sacral neuromodulation (SNM) on pregnancy and vice-versa, by identifying women who had received SNM for lower-urinary tract symptoms (LUTS) and had become pregnant. A cross-sectional descriptive study was carried out based on responses to an on-line questionnaire sent to practitioners listed on the InterStim enCaptureTM National Registry. Questions were related to pre-pregnancy health and SNM efficacy, deactivation of the device, its impact on LUTS, childbirth, the infant, its reactivation and postpartum effectiveness. Twenty-seven pregnancies were recorded among 21 women. Six women had had a pregnancy prior to implantation, two of whom had had a c-section. A total of 18.5% of women had the device disabled prior to conception. The others had their device disabled during the first trimester and did not reactivate it before delivery. Complications were reported in 25.9% of pregnancies: six women had urinary infections, including three of the four treated for chronic retention of urine (CRU), and 1 woman had pain at the stimulation site. There were 24 live births (including one premature birth and four c-sections), one spontaneous miscarriage and two voluntary interruptions of pregnancy. No neonatal disorders have been reported. Effectiveness of sacral neuromodulation decreased in 20% in postpartum. In 27 pregnancies established during SNM for LUTS, 18.5% of patients deactivated their case before pregnancy and the others switched it off during the first trimester. Three-quarters of women with CRU had urinary infection. No adverse effects on fetuses were found. SNM effectiveness deteriorated in 20% cases after childbirth. © 2017 Wiley Periodicals, Inc.

  13. The value of a core clinical rotation in urology for medical students.

    In 2013, our institution underwent a change to the undergraduate medical curriculum whereby a clinical urology rotation became mandatory. In this paper, we evaluated the perceived utility and value of this change in the core curriculum. Third year medical students, required to complete a mandatory 1-week clinical urology rotation, were asked to complete a survey before and after their rotation. Fourth year medical students, not required to complete this rotation, were also asked to complete a questionnaire. Chi-squared and Fisher's exact test were used for data analysis. In total, 108 third year students rotated through urology during the study period. Of these, 66 (61%) completed the pre-rotation survey and 54 (50%) completed the post-rotation survey. In total, there were 110 fourth year students. Of these, 44 (40%) completed the questionnaire. After completing their mandatory rotations, students felt more comfortable managing and investigating common urological problems, such as hematuria and renal colic. Students felt they had a better understanding of how to insert a Foley catheter and felt comfortable independently inserting a Foley catheter. Importantly, students felt they knew when to consult urology and were also more likely to consider a career in urology. Compared to fourth year students, third year students felt urology was an important component to a family medicine practice and felt they had a better understanding of when to consult urology. The introduction of a mandatory urology rotation for undergraduate medical students leads to a perceived improvement in fundamental urological knowledge and skill set of rotating students. This mandatory rotation provides a valuable experience that validates its inclusion.

    Since the last World Health Organization (WHO) classification scheme for tumours of the urinary tract and male genital organs, there have been a number of advances in the understanding, classification, immunohistochemistry and genetics of testicular germ cell tumours. The updated 2016 draft classification was discussed at an International Society of Urological Pathology Consultation on Testicular and Penile Cancer. This review addresses the main updates to germ cell tumour classification. Major changes include a pathogenetically derived classification using germ cell neoplasia in situ (GCNIS) as a new name for the precursor lesion, and the distinction of prepubertal tumours (non-GCNIS-derived) from postpubertal-type tumours (GCNIS-derived), acknowledging the existence of rare benign prepubertal-type teratomas in the postpubertal testis. Spermatocytic tumour is adopted as a replacement for spermatocytic seminoma, to avoid potential confusion with the unrelated usual seminoma. The spectrum of trophoblastic tumours arising in the setting of testicular germ cell tumour continues to expand, to include epithelioid and placental site trophoblastic tumours analogous to those of the gynaecological tract. Currently, reporting of anaplasia (seminoma or spermatocytic tumour) or immaturity (teratoma) is not required, as these do not have demonstrable prognostic importance. In contrast, overgrowth of a teratomatous component (somatic-type malignancy) and sarcomatous change in spermatocytic tumour indicate more aggressive behaviour, and should be reported. © 2016 John Wiley & Sons Ltd.

    Ureteroscopy is a minimally invasive procedure for diagnosis and treatment of urinary tract pathology. Ergonomic and visualization challenges as well as radiation exposure are limitations to conventional ureteroscopy. Therefore, we have developed a robotic system to "power drive" a flexible ureteroscope with 3D tip tracking and pre-operative image overlay. The proposed system was evaluated using a kidney phantom registered to pre-operative MR images. Initial experiments show the potential of the device to provide additional assistance, precision, and guidance during urology procedures.

    Introduction The functioning of modern urological departments and the high level of service they provide is possible through, among other things, the use of modern laser techniques. Material and methods Open operations have been replaced by minimally invasive procedures, and classical surgical tools by advanced lasers. The search for new applications with lasers began as technology developed. Among many devices available, holmium, diode and thulium lasers are currently the most popular. Results Depending on the wavelength, the absorption by water and hemoglobin and the depth of penetration, lasers can be used for coagulation, vaporization and enucleation. In many centres, after all the possibilities of pharmacological treatment have been exhausted, lasers are used as the primary treatment for patients with benign prostatic hyperplasia, with therapeutic results that are better than those obtained through open or endoscopic operations. The use of lasers in the treatment of urolithiasis, urinary strictures and bladder tumours has made treatment of older patients with multiple comorbidities safe, without further necessity to modify the anticoagulant drug treatment. Laser procedures are additionally less invasive, reduce hospitalization time and enable a shorter bladder catheterization time, sometimes even eliminating the need for bladder catherterization completely. Such procedures are also characterized by more stable outcomes and a lower number of reoperations. Conclusions There are also indications that with the increased competition among laser manufacturers, decreased purchase and maintenance costs, and increased operational safety, laser equipment will become mandatory and indispensable asset in all urology wards.

    The shortage of surgeon is one of the serious problems in Japan. To solve the problem, various efforts have been undertaken to improve surgical education and training. However, appropriate teaching methods in the operating room have not been well established. The aim of this study is to assess the utility of a novel interactive educational (IE) system for surgical education on urologic surgeries in the operating room. A total of 20 Japanese medical students were educated on urologic surgery using the IE system in the operating room. The IE system consists of two parts. The first is three-dimensional (3D) magnified vision of the operative field using a 3D head-mounted display and a 3D endoscope. The second is interactive educative communication between medical students and surgeons using a small-sized wireless communication device. The satisfaction level with the IE system and the physical burden on medical students was examined via questionnaire. All students utilized the IE system in urologic surgery and responded to the survey. Most students were satisfied with the IE system. They also felt more welcomed by the surgeon when using the IE system than when not using it. No major unpleasant symptoms were observed but five students (25 %) experienced mild eye fatigue as a result of viewing the medical images. The IE system has the potential to motivate students to become interested in surgery and could be an efficient method of surgical education in the operating room.

A Medline literature search was performed to elucidate all relevant studies of nanotechnology with specific attention to its application in urology. Urological applications of nanotechnology include its use in medical imaging, gene therapy, drug delivery, and photothermal ablation of tumours. In vitro and animal studies have shown initial encouraging results. Further study of nanotechnology for urological applications is warranted to bridge the gap between preclinical studies and translation into clinical practice, but nanomedicine has shown significant potential to improve urological patient care. © 2014 The Authors.

    2014-08-01

    Urology is affected by the demographic development in Germany more than any other medical discipline. Despite a relatively stable total population, by the year 2040 there will be an absolute and relevant increase in urological diseases caused only by the demographic development in the population. This is particularly true for the increase in oncological treatment just in the field of the discipline of urology. Even now the current numbers for tumor development in Germany (RKI 2014) in the urological oncology segment of all tumor diseases show an increasing trend with more than 23 %. This significant increase in performance is in contrast to the age development of the specialists in this discipline. In total but especially due to the significantly over-aged specialist medical profession in urology, this leads to a substantial bottleneck of specialists in the discipline of urology. This deficiency of personnel resources in urology is aggravated by the requirements of Generation Y for a well-adjusted work-life balance and the associated feminization of the medical profession. This requires intelligent strategies for.

    Organic Light Emitting Diodes (OLEDs) provide various attractive features for next generation illumination systems, including high efficiency, low power, thin and flexible form factor. In this work, we incorporated phosphorescent emitters and demonstrated highly efficient white phosphorescent OLED (PHOLED) devices on flexible plastic substrates. The 0.94 cm2 small-area device has total thickness of approximately 0.25 mm and achieved 63 lm/W at 1,000 cd/m2 with CRI = 85 and CCT = 2920 K. We further designed and fabricated a 15 cm x 15 cm large-area flexible white OLED lighting panels, finished with a hybrid single-layer ultra-low permeability single layer barrier (SLB) encapsulation film. The flexible panel has an active area of 116.4 cm2, and achieved a power efficacy of 47 lm/W at 1,000 cd/m2 with CRI = 83 and CCT = 3470 K. The efficacy of the panel at 3,000 cd/m2 is 43 lm/W. The large-area flexible PHOLED lighting panel is to bring out enormous possibilities to the future general lighting applications.

    Many patients consult emergency services with urological complaints. The aim of this study was to investigate the epidemiology, clinical presentation and treatments of urological emergency cases in a training and research hospital. We retrospectively evaluated urological emergency patients referred to the emergency unit between July 2012 and July 2013 according to age, gender, affected organ, radiological imaging techniques and treatment. Among 141.844 emergency cases, 3.113 (2.19%) were urological emergencies and 53.2% of the patients were male (mean age: 49.1), and 46.8% of them were female (median age: 42.8). The most frequent illness was genitourinary infection constituting 41.2% of the cases followed by renal colic (36.9%). Among the urological emergencies 483 (15.5%) patients were hospitalized and 152 surgical operations were performed. The mostly performed procedure was the placement of a suprapubic catheter in 34 patients constituting (22.3%) of the cases. Totally eight patients were referred to another experienced health center due to different reasons. Most of the urological emergency patients do not require emergency surgical interventions however, timely identification and management of urological emergencies with in-depth clinical evaluation are important to prevent late complications. Therefore the doctors working in emergency services must be heedful of urological emergencies.

    To analyze the association between US urology department Twitter presence and U.S. News and World Report (USNWR) reputation scores, to examine the content, informational value, and intended audience of these platforms, and to identify objectives for Twitter use. We identified Twitter accounts for urology departments scored in the 2016-2017 USNWR. Correlation coefficients were calculated between Twitter metrics (number of followers, following, tweets, and Klout influence scores) with USNWR reputation scores. We also performed a detailed content analysis of urology department tweets during a 6-month period to characterize the content. Finally, we distributed a survey to the urology department accounts via Twitter, inquiring who administers the content, and their objectives for Twitter use. Among 42 scored urology departments with Twitter accounts, the median number of followers, following, and tweets were 337, 193, and 115, respectively. All of these Twitter metrics had a statistically significant positive correlation with reputation scores (P <.05). Content analyses revealed that most tweets were about conferences, education, and publications, targeting the general public or urologic community. Survey results revealed that the primary reason for twitter use among urology departments was visibility and reputation, and urologists are considered the most important target audience. There is statistically significant correlation between Twitter activity and USNWR reputation scores for urology departments. Our results suggest that Twitter provides a novel mechanism for urology departments to communicate about academic and educational topics, and social media engagement can enhance reputation.

    In 1994, the Canadian urology residency training programs designed the "Canadian Urology Fair"--a single-site (Toronto, Ont.), 1-day fair to conduct the personal interview portion of the residency selection process. The objective of the current study was to evaluate the success of the Urology Fair in achieving its original goals of decreasing the financial burden and minimizing time away from medical training for applicants and faculty. Both candidates and Canadian urology training programs were surveyed regarding the financial and academic costs (days absent) of attending the 2001 Urology Fair. Data from the 2001 Canadian Resident Matching Service (CaRMS) was used to compare the financial and academic costs of attending personal interviews incurred by candidates declaring urology as their first-choice discipline to candidates interviewing with other surgical specialties throughout Canada. Financial costs incurred by candidates to attend the Urology Fair (mean Can dollar 367) were significantly lower than candidates' estimated costs of attending on-site interviews at the individual programs (mean Can dollar 2065). The financial costs of attending personal interviews by CaRMS applicants declaring urology as their first-choice discipline (mean Can dollar 2002) were significantly lower than the costs incurred by applicants interviewing with other surgical disciplines (mean Can dollar 2744). Financial costs to urology programs attending the fair (mean Can dollar 1931) were not significantly greater than the programs' estimated costs of conducting on-site interviews at their respective program locations (mean Can dollar 1825). Days absent from medical school to attend interviews were significantly lower among CaRMS applicants declaring urology as their first-choice discipline (3 d) compared with applicants who interviewed with other surgical specialties (9.1 d). The Canadian Urology Fair represents an innovative and efficient method for residency programs to conduct the personal interview portion of the residency selection process and should serve as a model for making the interview process less expensive and time-consuming for both candidates and faculty.

    We characterized urological symptoms in a subset of patients with urological chronic pelvic pain syndrome who have a high somatic symptom burden and a wide symptom distribution fitting a polysymptomatic, polysyndromic presentation pattern. A total of 81 patients with urological chronic pelvic pain syndrome enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases MAPP Research Network Study at Washington University in St. Louis and University of Alabama at Birmingham sites. They completed a symptom questionnaire to assess the somatic symptom burden and its distribution, and GUPI (Genitourinary Pain Index) to assess urological chronic pelvic pain syndrome symptoms, impact on quality of life and self-reported treatment seeking behaviors for urological chronic pelvic pain symptoms. The polysymptomatic, polysyndromic symptom pattern was defined by self-report of numerous painful and nonpainful somatic symptoms across many organ systems and by symptom categories on the polysymptomatic, polysyndromic questionnaire. Patients with urological chronic pelvic pain syndrome and the symptom pattern reported more severe genitourinary pain on a Likert scale, more frequent pain in the last week and more widespread pain distribution in the genital and pelvic areas than patients with urological chronic pelvic pain syndrome without the pattern. Patients with the symptom pattern also had significantly higher scores on the GUPI pain subscale, quality of life subscale (worse) and total questionnaire scores than patients without the pattern. Patients with the pattern reported significantly more treatment seeking behavior than others. The polysymptomatic, polysyndromic pattern might be an important phenotypic factor to assess in the evaluation of urological chronic pelvic pain syndrome with clinical and research implications. This may be a distinct clinical subgroup among patients with urological chronic pelvic pain syndrome. Copyright © 2014 American Urological Association Education and Research, Inc.

    Overactive bladder (OAB) is one of the most common syndromes of lower urinary tract dysfunction. Besides standard therapy using anticholinergic medications, comprehensive management of overactive bladder includes physiotherapy. To test the clinical effectiveness and safety of autonomous electrostimulation device "Erektron" in treating OAB in women. The study was conducted at the Urology and Gynecology Clinic of the Innovative Medical Technology Center between 25.04.2014 and 30.01.2015. It included 20 women with newly diagnosed OAB both with and without urinary urgency incontinence or urinary stress incontinence. The patients were divided into 2 groups. All patients were treated with the first line anticholinergic agent solifenacin 5 mg daily. In patients of group 1, anticholinergic therapy was administered concurrently with intravaginal electrostimulation using "Erektron" device. In both groups, the treatment resulted in positive results, but a more pronounced improvement was found in group 1 patients with mixed incontinence. Autonomous electrostimulation device MT-RV "Erektron" can be used in comprehensive management of patients with OAB, including those with stress urinary incontinence.

    The four-kallikrein panel and the Prostate Health Index (PHI) have been shown to improve prediction of prostate cancer (PCa) compared with prostate-specific antigen (PSA). No comparison of the four-kallikrein panel and PHI has been presented. To compare the four-kallikrein panel and PHI for predicting PCa in an independent cohort. Participants were from a population-based cohort of PSA-tested men in Stockholm County. We included 531 men with PSA levels between 3 and 15 ng/ml undergoing first-time prostate biopsy during 2010-2012. Models were fitted to case status. We computed calibration curves, the area under the receiver-operating characteristics curve (AUC), decision curves, and percentage of saved biopsies. The four-kallikrein panel showed AUCs of 69.0 when predicting any-grade PCa and 71.8 when predicting high-grade cancer (Gleason score ≥7). Similar values were found for PHI: 70.4 and 71.1, respectively. Both models had higher AUCs than a base model with PSA value and age (p<0.0001 for both); differences between models were not significant. Sensitivity analyses including men with any PSA level or a previous biopsy did not materially affect our findings. Using 10% predicted risk of high-grade PCa by the four-kallikrein panel or PHI of 39 as cut-off for biopsy saved 29% of performed biopsies at a cost of delayed diagnosis for 10% of the men with high-grade cancers. Both models showed limited net benefit in decision analysis. The main study limitation was lack of digital rectal examination data and biopsy decision being based on PSA information. The four-kallikrein panel and PHI similarly improved discrimination when predicting PCa and high-grade PCa. Both are simple blood tests that can reduce the number of unnecessary biopsies compared with screening with total PSA, representing an important new option to reduce harm. Prostate-specific antigen screening is controversial due to limitations of the test. We found that two blood tests, the Prostate Health Index and the four-kallikrein panel, performed similarly and could both aid in decision making among Swedish men undergoing a prostate biopsy.

    1998-09-01

    Hydronephrosis secondary to pelviureteric junction (PUJ) obstruction is common in infancy and childhood. Pyeloplasty has until recently been the accepted method of management, but alternative endo-urological techniques have evolved in the last decade. Published results of conventional pyeloplasty for primary PUJ obstruction in children were compared with published results of endo-urological procedures. Sixty-six pyeloplasties were performed in 61 children in a 6-year period. During a similar period, 63 primary endo-urological procedures were reported in the literature. The success rate after pyeloplasty was 95.5% compared with 65% after endo-urology. Conventional pyeloplasty is superior to endo-urology and should remain the gold standard for the treatment of primary PUJ obstruction in children.

    2013-02-01

    Over the past 18 years, several electrosurgical systems generating a low temperature plasma in an aqueous conductive solution have been commercialized for various clinical applications and have been used in over 10 million patients to date. The most popular utilizations are in arthroscopic surgery, otorhinolaryngology surgery, spine and neurosurgery, urology and wound care. These devices can be configured to bring saline to the tip and to have concomitant aspiration to remove by-products and excess fluid. By tuning the electrode geometry, waveform and fluid dynamic at the tip of the devices, tissue resection and thermal effects can be adjusted individually. This allows one to design products that can operate as precise tissue dissectors for treatment of articular cartilage or debridement of chronic wounds, as well as global tissue debulking devices providing sufficient concomitant hemostasis for applications like tonsillectomies. Effects of these plasma based electrosurgical devices on cellular biology, healing response and nociceptive receptors has also been studied in various models. This talk will include a review of the clinical applications, with product descriptions, results and introductory review of some of the research on the biological effects of these devices.

    We researched the start of urological specialisation in Spain, from the end of the 19th century to the institution of the education system (resident medical intern) to learn about the centres and individuals who created the urological teaching units and training schools in which the first Spanish urologists specialised their training. We extracted the references from books on the history of urology, from periodic urological publications and from the posters on history submitted to the congresses of the Spanish Urological Association and filled in the data and dates with the Historical Dictionary of Spanish Urologists. There are 30 urological specialization centres, 8 with official accreditation recognised by the corresponding ministry but whose official status is unknown. These centres are in the urology departments of large Spanish hospitals, university clinic hospitals and in private schools directed by notable urologists. There are 14 main centres, corresponding chronologically to the following cities: Madrid, Barcelona, Santiago de Compostela, Seville, Las Palmas of Gran Canaria, Cadiz, Santander, Valencia, Granada, Bilbao, San Sebastian, Oviedo, Zaragoza and Salamanca. Urological training in Spain from the end of the 19th century to the first half of the 20th century was well-established, both in officially accredited centres and in the urology departments of the main hospitals, in university clinic hospitals and in private schools and clinics. The training was directed by experienced urologists who ensured proper teaching and training, a method that persisted until the institution of the resident medical intern system in 1970.

    The aim of this research was to study the trends in authorship and type of article in European and North American journals of urology over the past 6 decades. Using a self-developed Visual Basic program, the number of authors per article and the type of article in four European journals (BJU International, Current Opinion in Urology, European Urology and Urologia Internationalis) and four North American journals (Journal of Urology, Urologic Clinics of North America, Urology and World Journal of Urology) were extracted from the PubMed website from January 1946 to October 2010, and the number of authors per article in each year was calculated in all the journals. The average number of authors per article has increased and the percentage of single-author articles has decreased in both European and American journals. An increase in the number of authors per article was observed mainly in original articles and case reports. Since the early 1980s, there has also been a decreasing percentage of published case reports and a general increase in the percentage of letters to the editor and editorials. The multiple-authorship trends observed in both European and North American urology journals were similar and appeared to be mainly due to changes in original articles and case reports.

    The role of basic science exposure during urology training is a timely topic that is relevant to urologic health and to the training of new physician scientists. Today, researchers are needed for the advancement of this specialty, and involvement in basic research will foster understanding of basic scientific concepts and the development of critical thinking skills, which will, in turn, improve clinical performance. If research education is not included in urology training, future urologists may not be as likely to contribute to scientific discoveries.Currently, only a minority of urologists in training are currently exposed to significant research experience. In addition, the number of physician-scientists in urology has been decreasing over the last two decades, as fewer physicians are willing to undertake a career in academics and perform basic research. However, to ensure that the field of urology is driving forward and bringing novel techniques to patients, it is clear that more research-trained urologists are needed. In this article we will analyse the current status of basic research in urology training and discuss the importance of and obstacles to successful addition of research into the medical training curricula. Further, we will highlight different opportunities for trainees to obtain significant research exposure in urology.

  8. Robotic surgery in urologic oncology: gathering the evidence.

    2010-08-01

    In less than a decade, the widespread application of robotic technology to the field of urologic oncology has permanently altered the way urologists approach malignancy. The short-term benefits of minimally invasive surgery using robotic assistance (i.e., decreased blood loss, improved convalescence and ergonomic appeal), as well as a broad marketing campaign, have helped the technology gain traction in the field of urology. Although the long-term benefits of its use in urologic surgery are less clear and the costs of robotic surgery are consistently greater than those of other approaches, the numbers of prostate, kidney and bladder cancer cases continue to rise. Identifying transferable surgical processes of care that matter most for each of the robotic cases in urologic oncology (e.g., prostatectomy, cystectomy and partial nephrectomy) is a next step toward broadly improving the quality of urologic cancer care. To this end, urologic professional societies and their surgeons should aim to identify underwriters for and participate in large clinical registries and surgical quality collaboratives.

    We seek to provide a background of the current state of pediatric urologic surgery including a brief history, procedural outcomes, cost considerations, future directions, and the state of robotic surgery in India. Pediatric robotic urology has been shown to be safe and effective in cases ranging from pyeloplasty to bladder augmentation with continent urinary diversion. Complication rates are in line with other methods of performing the same procedures. The cost of robotic surgery continues to decrease, but setting up pediatric robotic urology programs can be costly in terms of both monetary investment and the training of robotic surgeons. The future directions of robot surgery include instrument and system refinements, augmented reality and haptics, and telesurgery. Given the large number of children in India, there is huge potential for growth of pediatric robotic urology in India. Pediatric robotic urologic surgery has been established as safe and effective, and it will be an important tool in the future of pediatric urologic surgery worldwide. PMID:25197187

    Prostate-specific antigen (PSA) screening reduces prostate cancer deaths but leads to harm from overdiagnosis and overtreatment. To determine the long-term risk of prostate cancer mortality using kallikrein blood markers measured at baseline in a large population of healthy men to identify men with low risk for prostate cancer death. Study based on the Malmö Diet and Cancer cohort enrolling 11 506 unscreened men aged 45-73 yr during 1991-1996, providing cryopreserved blood at enrollment and followed without PSA screening to December 31, 2014. We measured four kallikrein markers in the blood of 1223 prostate cancer cases and 3028 controls. Prostate cancer death (n=317) by PSA and a prespecified statistical model based on the levels of four kallikrein markers. Baseline PSA predicted prostate cancer death with a concordance index of 0.86. In men with elevated PSA (≥2.0ng/ml), predictive accuracy was enhanced by the four-kallikrein panel compared with PSA (0.80 vs 0.73; improvement 0.07; 95% confidence interval 0.04, 0.10). Nearly half of men aged 60+ yr with elevated PSA had a four-kallikrein panel score of <7.5%, translating into 1.7% risk of prostate cancer death at 15 yr-a similar estimate to that of a man with a PSA of 1.6ng/ml. Men with a four-kallikrein panel score of ≥7.5% had a 13% risk of prostate cancer death at 15 yr. A prespecified statistical model based on four kallikrein markers (commercially available as the 4Kscore) reclassified many men with modestly elevated PSA, to have a low long-term risk of prostate cancer death. Men with elevated PSA but low scores from the four-kallikrein panel can be monitored rather than being subject to biopsy. Men with elevated prostate-specific antigen (PSA) are often referred for prostate biopsy. However, men with elevated PSA but low scores from the four-kallikrein panel can be monitored rather than being subject to biopsy. Copyright © 2018 European Association of Urology.

    The safety of 6 modified terephthalate polymers as cosmetic ingredients was assessed. These ingredients mostly function as exfoliants, bulking agents, hair fixatives, and viscosity-increasing agents-nonaqueous. Polyethylene terephthalate (PET) is used in leave-on products up to 100% and in rinse-off products up to 2%. The Cosmetic Ingredient Review Expert Panel (Panel) considered that the PET used in cosmetics is chemically equivalent to that used in medical devices. The Panel determined that the Food and Drug Administration's determination of safety of PET in several medical devices, which included human and animal safety data, can be used as the basis for the determination of safety of PET and related polymers used in cosmetics. Use studies of cosmetic eye products that contain PET demonstrated no ocular irritation or dermal sensitization. The Panel concluded that modified terephthalate polymers were safe as cosmetic ingredients in the practices of use and concentration described in this safety assessment. © The Author(s) 2014.

    PubMed

    Loch, Tillmann; Carey, Brendan; Walz, Jochen; Fulgham, Pat Fox

    2015-05-01

    The terminology and abbreviations used in urologic imaging have generally been adopted on an ad hoc basis by different speciality groups; however, there is a need for shared nomenclature to facilitate clinical communication and collaborative research. This work reviews the current nomenclature for urologic imaging used in clinical practice and proposes a taxonomy and terminology for urologic imaging studies. A list of terms used in urologic imaging were compiled from guidelines published by the European Association of Urology and the American Urological Association and from the American College of Radiology Appropriateness Criteria. Terms searched were grouped into broad categories based on technology, and imaging terms were further stratified based on the anatomic extent, contrast or phases, technique or modifiers, and combinations or fusions. Terms that had a high degree of utilisation were classified as accepted. We propose a new taxonomy to define a more useful and acceptable nomenclature model acceptable to all health professionals involved in urology. The major advantage of a taxonomic approach to the classification of urologic imaging studies is that it provides a flexible framework for classifying the modifications of current imaging modalities and allows the incorporation of new imaging modalities. The adoption of this hierarchical classification model ranging from the most general to the most detailed descriptions should facilitate hierarchical searches of the medical literature using both general and specific terms. This work is limited in its scope, as it is not currently all-inclusive. This will hopefully be addressed by future modification as others embrace the concept and work towards uniformity in nomenclature. This paper provides a noncomprehensive list of the most widely used terms across different specialties. This list can be used as the basis for further discussion, development, and enhancement. In this paper we describe a classification system for urologic imaging terms with the aim of aiding health professionals and ensuring that the terms used are more consistent.

    Background The script concordance (SC) test is an assessment tool that measures capacity to solve ill-defined problems, that is, reasoning in context of uncertainty. This tool has been used up to now mainly in medicine. The purpose of this pilot study is to assess the feasibility of the test delivered on the Web to French urologists. Methods The principle of SC test construction and the development of the Web site are described. A secure Web site was created with two sequential modules: (a) The first one for the reference panel (n = 26) with two sub-tasks: to validate the content of the test and to elaborate the scoring system; (b) The second for candidates with different levels of experience in Urology: Board certified urologists, residents, medical students (5 or 6th year). Minimum expected number of participants is 150 for urologists, 100 for residents and 50 for medical students. Each candidate is provided with an individual access code to this Web site. He/she may complete the Script Concordance test several times during his/her curriculum. Results The Web site has been operational since April 2004. The reference panel validated the test in June of the same year during the annual seminar of the French Society of Urology. The Web site is available for the candidates since September 2004. In six months, 80% of the target figure for the urologists, 68% of the target figure for the residents and 20% of the target figure for the student passed the test online. During these six months, no technical problem was encountered. Conclusion The feasibility of the web-based SC test is successful as two-thirds of the expected number of participants was included within six months. Psychometric properties (validity, reliability) of the test will be evaluated on a large scale (N = 300). If positive, educational impact of this assessment tool will be useful to help urologists during their curriculum for the acquisition of clinical reasoning skills, which is crucial for professional competence.

    Penile prosthesis implant surgery is an effective management approach for a number of urological conditions, including medication refractory erectile dysfunction (ED). Complications encountered post-operatively include infection, bleeding/hematoma, and device malfunction. Since the 1970s, modifications to these devices have reduced complication rates through improvement in antisepsis and design using antibiotic coatings, kink-resistant tubing, lock-out valves to prevent autoinflation, and modified reservoir shapes. Device survival and complication rates have been investigated predominately by retrospective database-derived studies. This review article focuses on the identification and management of post-operative complications following penile prosthetic and implant surgery. Etiology for ED, surgical technique, and prosthesis type are variable among studies. The most common post-operative complications of infection, bleeding, and device malfunction may be minimized by adherence to consistent technique and standard protocol. Novel antibiotic coatings and standard antibiotic regimen may reduce infection rates. Meticulous hemostasis and intraoperative testing of devices may further reduce need for revision surgery. Additional prospective studies with consistent reporting of outcomes and comparison of surgical approach and prosthesis type in patients with variable ED etiology would be beneficial. PMID:29238663

    Recent research suggests that low education and illiteracy may drive misunderstanding of the American Urological Association Symptom Score, a key tool in the American Urological Association benign prostatic hyperplasia guidelines. It is unclear whether misunderstanding is confined to patients of low socioeconomic status. Therefore, we reevaluated the prevalence and impact of this misunderstanding in a county vs university hospital population. This prospective study involved 407 patients from a county hospital and a university hospital who completed the American Urological Association Symptom Score as self-administered and then as interviewer administered. Responses were compared by calculating correlation coefficients and weighted kappa statistics to assess patient understanding of the American Urological Association Symptom Score. Multivariate logistic regression analyses were used to examine the association between patient characteristics and poor understanding of the American Urological Association Symptom Score. Of the patients 72% understood all 7 American Urological Association Symptom Score questions. Of the measured demographic variables only education level significantly affected this understanding. Compared to patients with more than 12 years of education county hospital patients with less than 9 years of education were 57.06 times more likely to misunderstand the American Urological Association Symptom Score (95% CI 14.32-329.34) while university hospital patients with less than 9 years of education were 38.27 times more likely to misunderstand the American Urological Association Symptom Score (95% CI 1.69-867.83). Of county hospital patients 31% and of university hospital patients 21% significantly misrepresented their symptom severity according to current guidelines. Patients with low education regardless of location are more likely to misunderstand the American Urological Association Symptom Score, misrepresent their symptoms and, therefore, receive inappropriate treatment.

    Objective of this study is to provide an evidence-based analysis of the current status and future perspectives of scarless urological surgery. A PubMed search has been performed for all relevant urological literature regarding natural orifice transluminal endoscopic surgery (NOTES) and laparoendoscopic single-site surgery (LESS). In addition, experience with LESS and NOTES at our own institution has been considered. All clinical and investigative reports for LESS and NOTES procedures in the urological literature have been considered. A wide variety of clinical procedures in urology have been successfully completed by using LESS techniques. Thus far, experience with NOTES has largely been investigational, although early clinical reports are emerging. Further development of instrumentation and platforms is necessary for both techniques to become more widely adopted throughout the urological community.

    Objective To analyze the publication rates of full-text journal articles converted from the abstracts presented in the 22nd Turkish National Urology Congress in 2012. Material and Methods A total of 576 abstracts accepted for presentation at the 22nd Turkish National Urology Association Meeting were identified from the published abstract book. The abstracts were categorized into subsections such as endourology and pediatric urology. The subsequent publication rate for the studies was evaluated by scanning PubMed Medline. Abstracts published before the proceedings were excluded from the study. Results The abstracts were categorized as being presented orally (n=155), by poster (n=421), or by video (n=78). Of the 28 (18.3%) of 155 oral and 34 (8.15%) of 421 poster presentations, were subsequently published in several journals until March 2015. The publication rates of the abstracts based on urology subsections were as follows: neurology (25%), andrology (18.6%), endourology (17.2%), urolithiasis (15.3%), general urology (12.5%), infectious diseases (7.14%), pediatric urology (6.25%), uro-gynecology (6.06%), reconstructive urology (5.8%), and urooncology (3.8%). The average time to publication was 11.77 (0–33) months. Conclusion This is the first study assessing the publication rates of abstracts presented at a Turkish National Urology Congress. It reveals that more qualified randomized studies need to be done to improve the rate of publication. PMID:27011876

    Objective In addition to being prevalent and bothersome, urologic and sexual symptoms may be related to chronic medical illnesses. We investigate the relationship between ten urologic and sexual symptoms and four major illnesses (type II diabetes, cardiac disease, hypertension, and depression). Methods We analyze data from the Boston Area Community Health (BACH) Survey, a community-based epidemiologic study of urologic symptoms and risk factors. BACH used a two-stage stratified cluster sampling design to recruit 5,506 adults aged 30–79 (2,301 men, 3,205 women; 1,770 Black, 1,877 Hispanic, and 1,859 White respondents). Results In bivariate analyses, most urologic and sexual symptoms are associated with type II diabetes, cardiac disease, hypertension, and depression. However, in multivariate models adjusting for all four illnesses, gender, race/ethnicity, age, alcohol intake, smoking, physical activity, and body mass index there were fewer significant associations. We found that all urologic symptoms were significantly related to at least one illness, with depression increasing the odds of all urologic and sexual symptoms studied. Conclusions Urinary tract specialists may need to give greater weight to consideration of factors outside the urinary tract that may be contributing to urologic symptoms. It remains unknown whether treatment of medical and psychological illnesses can result in meaningful improvement in urologic symptoms, or conversely, whether urinary tract symptoms can provide valuable insight into an individual’s overall health status.

  6. Characterizing the reflectivity of handheld display devices.

    2014-08-01

    With increased use of handheld and tablet display devices for viewing medical images, methods for consistently measuring reflectivity of the devices are needed. In this note, the authors report on the characterization of diffuse reflections for handheld display devices including mobile phones and tablets using methods recommended by the American Association of Physicists in Medicine Task Group 18 (TG18). The authors modified the diffuse reflectance coefficient measurement method outlined in the TG18 report. The authors measured seven handheld display devices (two phones and five tablets) and three workstation displays. The device was attached to a black panel with Velcro. To study the effect of the back surface on the diffuse reflectance coefficient, the authors created Styrofoam masks with different size square openings and placed it in front of the device. Overall, for each display device, measurements of illuminance and reflected luminance on the display screen were taken. The authors measured with no mask, with masks of varying size, and with display-size masks, and calculated the corresponding diffuse reflectance coefficient. For all handhelds, the diffuse reflectance coefficient measured with no back panel were lower than measurements performed with a mask. The authors found an overall increase in reflectivity as the size of the mask decreases. For workstations displays, diffuse reflectance coefficients were higher when no back panel was used, and higher than with masks. In all cases, as luminance increased, illuminance increased, but not at the same rate. Since the size of handheld displays is smaller than that of workstation devices, the TG18 method suffers from a dependency on illumination condition. The authors show that the diffuse reflection coefficients can vary depending on the nature of the back surface of the illuminating box. The variability in the diffuse coefficient can be as large as 20% depending on the size of the mask. For all measurements, both luminance and illuminance increased as the size of the display window decreased. The TG18 method does not account for this variability. The authors conclude that the method requires a definitive description of the back panel used in the light source setup. The methods described in the TG18 document may need to be improved to provide consistent comparisons of desktop monitors, phones, and tablets.

    Playing video games in childhood may help achieve advanced laparoscopic skills later in life. The virtual operating room will soon become a reality, as "doctor games 2.0" will doubtlessly begin to incorporate virtual laparoscopic techniques. To teach surgical skills to schoolchildren in order to attract them to urology as a professional choice later in life. As part of EAU Urology Week 2010, 108 school children aged 15-19 attended a seminar with lectures and simulators (laparoscopy, TUR, cystoscopy, and suture sets) at the 62nd Congress of the German Society of Urology in Düsseldorf. A Pub-Med and Google Scholar search was also performed in order to review the beneficial effects of early virtual surgical training. MeSh terms used were "video games," "children," and "surgical skills." Searches were performed without restriction for a certain period of time. In terms of publicity for urology, EAU Urology Week, and the German Society of Urology, the event was immensely successful. Regarding the literature search, four relevant publications were found involving children. An additional three articles evaluated the usefulness of video gaming in medical students and residents. Making use of virtual reality to attract and educate a new generation of urologists is an important step in designing the future of urology.

    2016-04-01

    Over recent years, Twitter has demonstrated an expanding role in scientific discussion, surgical news and conferences. This study evaluates the role of Twitter in urological conferences, with comparison to other surgical specialties. A retrospective analysis of Twitter metrics during the two largest recent English-speaking conferences for each surgical specialty was performed. Using www.symplur.com, all 'tweets' under the official conference hashtag from 0000 hour the first day to 24.00 hour the final day were assessed. The number of impressions, 'tweeters' and rates of 'tweeting' were analysed. Nine of 18 conferences examined had official hashtags registered with Symplur Healthcare Hashtags. Plastic and urological surgery had both major conferences registered. Only one of two conferences for each cardiothoracic, general, orthopaedic, otolaryngology and paediatric was registered. Both major neurosurgical and vascular conferences were unregistered. Urological conferences were associated with significantly more Twitter activity than non-urological surgical conferences in all parameters, with greater than triple the number of impressions, tweets and 'tweeters'. Urological surgical conferences were associated with 337% more tweets and 164% more impressions per conference day, than non-urological surgical conferences. Twitter has been used to supplement surgical conferences. In this regard, the urological community leads the way compared to the remainder of surgical specialty communities. © 2015 Royal Australasian College of Surgeons.

    In Arkansas, telemedicine is used commonly in obstetrics through Antenatal and Neonatal Guidelines, Education and Learning System (ANGELS), the existing statewide telemedicine network. This network is used primarily for tele-ultrasound and maternal-fetal medicine consultation. This study is a retrospective case series, describing all the patients who had a prenatally diagnosed urologic anomaly that required prenatal urologic consultation. From 2009-2013, approximately 1300 anomalies were recorded in the Arkansas Fetal Diagnosis and Management (AFDM) database, 14% of which were urologic anomalies. Twenty-six cases required prenatal urologic consultation, 25 of which were conducted via telemedicine. Teleconsultation allowed patients to combine maternal-fetal medicine and urologic consultations in one visit, saving time and effort and ultimately, for most patients, providing reassurance that delivery could be accomplished locally with postnatal follow-up already arranged. While there are several studies reporting the use of telemedicine for various subspecialty consultations, to our knowledge, this is the first to describe the use of telemedicine for prenatal urology consultation. Future research could randomize patients prospectively to allow comparison of both the outcomes as well as the patient experience. © The Author(s) 2015.

    The development of structured and validated training curricula is one of the current priorities in robot-assisted urological surgery. To establish the feasibility, acceptability, face validity, and educational impact of a structured training curriculum for robot-assisted radical prostatectomy (RARP), and to assess improvements in performance and ability to perform RARP after completion of the curriculum. A 12-wk training curriculum was developed based on an expert panel discussion and used to train ten fellows from major European teaching institutions. The curriculum included: (1) e-learning, (2) 1 wk of structured simulation-based training (virtual reality synthetic, animal, and cadaveric platforms), and (3) supervised modular training for RARP. The feasibility, acceptability, face validity, and educational impact were assessed using quantitative surveys. Improvement in the technical skills of participants over the training period was evaluated using the inbuilt validated assessment metrics on the da Vinci surgical simulator (dVSS). A final RARP performed by fellows on completion of their training was assessed using the Global Evaluative Assessment of Robotic Skills (GEARS) score and generic and procedure-specific scoring criteria. The median baseline experience of participants as console surgeon was 4 mo (interquartile range [IQR] 0-6.5 mo). All participants completed the curriculum and were involved in a median of 18 RARPs (IQR 14-36) during modular training. The overall score for dVSS tasks significantly increased over the training period (p<0.001-0.005). At the end of the curriculum, eight fellows (80%) were deemed able by their mentors to perform a RARP independently, safely, and effectively. At assessment of the final RARP, the participants achieved an average score ≥4 (scale 1-5) for all domains using the GEARS scale and an average score >10 (scale 4-16) for all procedural steps using a generic dedicated scoring tool. In performance comparison using this scoring tool, the experts significantly outperformed the fellows (mean score for all steps 13.6 vs 11). The European robot-assisted urologic training curriculum is acceptable, valid, and effective for training in RARP. This study shows that a 12-wk structured training program including simulation-based training and mentored training in the operating room allows surgeons with limited robotic experience to increase their robotic skills and their ability to perform the surgical steps of robot-assisted radical prostatectomy.

    Extracorporeal shock wave lithotripsy (SWL) was first introduced in 1980 and it rapidly revolutionized the treatment of stone disease. SWL is a non-invasive, outpatient procedure that now accounts for the majority of stone removal procedures. Since the introduction of first generation lithotripter, the Dornier HM3 machine, SWL devices have undergone many modifications secondary to limitations, in efforts to create a more effective and efficient way to treat stones and decrease possible morbidities. Herein, we review the evolution of the technology and advances in the instrumentation over the last three decades. PMID:21116366

    The judicious use of immunostains can be of significant diagnostic assistance in the interpretation of testicular neoplasms when the light microscopic features are ambiguous. A limited differential diagnosis by traditional morphology is required for the effective use of immunohistochemistry (IHC); otherwise, the inevitable occurrence of exceptions to anticipated patterns will lead to "immunoconfusion." The diagnosis of tumors in the germ cell lineage, the great majority of primary tumors of the testis, has been considerably facilitated over the past decade by IHC directed at developmentally important nuclear transcription factors, including OCT4, SALL4, SOX2, and SOX17, that are mostly restricted to certain tumor histotypes. In conjunction with other markers, a specific diagnosis can be achieved in most instances through a panel of 3 or 4 immunostains and often fewer. IHC among tumors in the sex cord-stromal group may produce a significant proportion of false-negative cases until more sensitive and equally specific markers are validated. The negativity of these tumors for the IHC stains used for germ cell tumors is key in the important distinction of neoplasms in these 2 general categories. In this review, the International Society of Urological Pathologists (ISUP) provides diagnostic guidelines in the form of algorithms to assist practicing pathologists confronting a differential diagnostic question concerning a testicular neoplasm. The goal of ISUP is to anticipate commonly encountered differential diagnoses and recommend an efficient and limited pattern of IHC stains to resolve the question.

    Stress urinary incontinence is a common problem experienced by many women that can have a significant negative impact on the quality of life of those who suffer from the condition and potentially those friends and family members whose lives and activities may also be limited. A comprehensive search of the literature was performed by ECRI Institute. This search included articles published between January 2005 and December 2015 with an updated abstract search conducted through September 2016. When sufficient evidence existed, the body of evidence for a particular treatment was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions. The AUA (American Urological Association) and SUFU (Society of Urodynamics, Female Pelvic Medicine & Urogenital Reconstruction) have formulated an evidence-based guideline focused on the surgical treatment of female stress urinary incontinence in both index and non-index patients. The surgical options for the treatment of stress urinary incontinence continue to evolve; as such, this guideline and the associated algorithm aim to outline the currently available treatment techniques as well as the data associated with each treatment. Indeed, the Panel recognizes that this guideline will require continued literature review and updating as further knowledge regarding current and future options continues to grow.

    Solar panels are expected to play a major role as a source of sustainable energy. In order to evaluate solar panels, non-destructive tests, such as defect inspections and response property evaluations, are necessary. We developed a DC current distribution mapping system of the solar panels using a High Critical Temperature Superconductor Superconducting Quantum Interference Device (HTS-SQUID) gradiometer with ramp edge type Josephson junctions. Two independent components of the magnetic fields perpendicular to the panel surface (∂Bz/∂x, ∂Bz/∂y) were detected. The direct current of the solar panel is visualized by calculating the composition of the two signal components, the phase angle, and mapping the DC current vector. The developed system can evaluate the uniformity of DC current distributions precisely and may be applicable for defect detection of solar panels.

  19. Image degradation by glare in radiologic display devices

    1997-05-01

    No electronic devices are currently available that can display digital radiographs without loss of visual information compared to traditional transilluminated film. Light scattering within the glass faceplate of cathode-ray tube (CRT) devices causes excessive glare that reduces image contrast. This glare, along with ambient light reflection, has been recognized as a significant limitation for radiologic applications. Efforts to control the effect of glare and ambient light reflection in CRTs include the use of absorptive glass and thin film coatings. In the near future, flat panel displays (FPD) with thin emissive structures should provide very low glare, high performance devices. We have used an optical Monte Carlo simulation to evaluate the effect of glare on image quality for typical CRT and flat panel display devices. The trade-off between display brightness and image contrast is described. For CRT systems, achieving good glare ratio requires a reduction of brightness to 30-40 percent of the maximum potential brightness. For FPD systems, similar glare performance can be achieved while maintaining 80 percent of the maximum potential brightness.

    For the past few years, a hybrid generation system including solar panel and gas cogeneration is being used for residential houses. Solar panels can generate electronic power at daytime; meanwhile, it cannot generate electronic power at night time. But the power consumption of residential houses usually peaks in the evening. The gas engine cogeneration system can generate electronic power without such a restriction, and it also can generate heat power to warm up house or to produce hot water. In this paper, we propose the solar panel and gas engine co-generation hybrid system with an energy storage device that is combined by dc bus. If a black out occurs, the system still can supply electronic power for special house loads. We propose the control scheme for the system which are related with the charging level of the energy storage device, the voltage of the utility grid which can be applied both grid connected and stand alone operation. Finally, we carried out some experiments to demonstrate the system operation and calculation for loss estimation.

    2014-01-01

    PURPOSE The Affordable Care Act (ACA) is expected to provide coverage for nearly twenty-five million previously uninsured individuals. Because the potential impact of the ACA for urological care remains unknown, we estimated the impact of insurance expansion on the utilization of inpatient urological surgeries using Massachusetts (MA) healthcare reform as a natural experiment. METHODS We identified nonelderly patients who underwent inpatient urological surgery from 2003 through 2010 using inpatient databases from MA and two control states. Using July 2007 as the transition point between pre- and post-reform periods, we performed a difference-indifferences (DID) analysis to estimate the effect of insurance expansion on overall and procedure-specific rates of inpatient urological surgery. We also performed subgroup analyses according to race, income and insurance status. RESULTS We identified 1.4 million surgeries performed during the study interval. We observed no change in the overall rate of inpatient urological surgery for the MA population as a whole, but an increase in the rate of inpatient urological surgery for non-white and low income patients. Our DID analysis confirmed these results (all 1.0%, p=0.668; non-whites 9.9%, p=0.006; low income 6.6%, p=0.041). At a procedure level, insurance expansion caused increased rates of inpatient BPH procedures, but had no effect on rates of prostatectomy, cystectomy, nephrectomy, pyeloplasty or PCNL. CONCLUSIONS Insurance expansion in Massachusetts increased the overall rate of inpatient urological surgery only for non-whites and low income patients. These data inform key stakeholders about the potential impact of national insurance expansion for a large segment of urological care. PMID:25506058

    To elucidate the current portfolio of National Institutes of Health (NIH) funding to departments of urology at U.S. medical schools. The NIH Research Portfolio Online Reporting Tools Expenditures and Results was used to generate a comprehensive analysis of NIH research grants awarded to urology departments during 2014. Costs, mechanisms, and institutes were summarized with descriptive statistics. Demographic data were obtained for principal investigators and project abstracts were categorized by research type and area. Fiscal totals were calculated for 2005-2014 and compared with other surgical departments during 2014. One hundred one investigators at 36 urology departments received $55,564,952 in NIH funding during 2014. NIH-funded investigators were predominately male (79%) and PhD scientists (52%). Funding totals did not vary by terminal degree or sex, but increased with higher academic rank (P < .001). The National Cancer Institute (54.7%) and National Institute of Diabetes and Digestive and Kidney Diseases (32.2%) supported the majority of NIH-funded urologic research. The R01 grant accounted for 41.0% of all costs. The top 3 NIH-funded clinical areas were urologic oncology (62.1%), urinary tract infection (8.8%), and neurourology (7.6%). A minority of costs supported clinical research (12.9%). In 2014, urology had the least number of NIH grants relative to general surgery, ophthalmology, obstetrics & gynecology, otolaryngology, and orthopedic surgery. NIH funding to urology departments lags behind awards to departments of other surgical disciplines. Future interventions may be warranted to increase NIH grant procurement in urology.

    Kutikov, Alexander; Morgan, Todd M; Resnick, Matthew J

    2009-01-01

    Over the past 10 years, a dramatic shift has occurred toward web-based applications and information dissemination both for medical students applying to residency programs and for current housestaff seeking specialty-specific information. This shift has been witnessed in urology with adoption of the Internet-based Electronic Residency Application Service for residency application submission. Currently, most residency programs devote significant attention to developing and maintaining an attractive web page, as studies have suggested departmental websites may impact applicants' decisions regarding residency preference lists.(1,2) Recently, some third-party websites have been established to provide information to medical students and residents in a variety of specialties. No studies are available that evaluate the impact of these external websites on residency decision making. In 2003, a website under the domain name www.UrologyMatch.com was created by 2 coauthors (A.K. and T.M.M.) with the purpose of assisting medical students through the American Urological Association (AUA) match process. Additionally, by providing a discussion forum for students, residents, and faculty, it sought to aid with the dissemination of information between urology programs and applicants. The website has been gradually expanded to provide educational content for urology trainees at a wide range of levels. Components of the website include an introduction to the field of urology, a detailed description of the match process, an "expert advice" section from urologic leaders, a library of relevant Internet links, a digital surgical atlas, and program-specific questionnaire responses provided by residency directors and department chairs. A discussion board providing an uncensored forum for visitors is integrated into the website to aid with the dissemination of information between and among urology programs, residents, and applicants. The high usage of this site has suggested that external websites may have a marked impact on the residency application process. The purpose of the current study was to evaluate the role of www.UrologyMatch.com in the AUA match process. During the 2007-2008 urology residency match, we evaluated whether information disseminated through the website influenced medical students' decisions to enter the field of urology and whether this information factored into the generation of residency preference lists. We hypothesized that information on this website played a significant role in decision making throughout the urology residency match experience.

    Urology has always been seen as being on the cutting edge of technology and this has been especially prevalent in the past 10 to 15 years with a move to robotic surgery, increased use of laser technology, and stem cell research leading to organ regeneration. Urology has a number of subspecialties including pediatrics, urologic oncology, renal transplantation, male infertility and andrology, calculi, female urology, neurourology, and trauma and reconstruction. Urologists have a wide array of practice options ranging from performing major oncologic procedures with extensive reconstruction to having an office-based practice and performing endoscopic cases with everything else in between. Subspecialization is becoming increasingly more organized and regulated. Copyright © 2012 Elsevier Inc. All rights reserved.

    Background Playing video games in childhood may help achieve advanced laparoscopic skills later in life. The virtual operating room will soon become a reality, as “doctor games 2.0” will doubtlessly begin to incorporate virtual laparoscopic techniques. Objectives To teach surgical skills to schoolchildren in order to attract them to urology as a professional choice later in life. Materials and Methods As part of EAU Urology Week 2010, 108 school children aged 15–19 attended a seminar with lectures and simulators (laparoscopy, TUR, cystoscopy, and suture sets) at the 62nd Congress of the German Society of Urology in Düsseldorf. A Pub-Med and Google Scholar search was also performed in order to review the beneficial effects of early virtual surgical training. MeSh terms used were “video games,” “children,” and “surgical skills.” Searches were performed without restriction for a certain period of time. Results In terms of publicity for urology, EAU Urology Week, and the German Society of Urology, the event was immensely successful. Regarding the literature search, four relevant publications were found involving children. An additional three articles evaluated the usefulness of video gaming in medical students and residents. Conclusions Making use of virtual reality to attract and educate a new generation of urologists is an important step in designing the future of urology. PMID:23573467

    Objective was to investigate content of written information material and availability of sexual health care for men experiencing sexual dysfunction (SD) after prostate cancer treatment. A cross-sectional survey was conducted among Dutch urology and radiotherapy departments to evaluate information materials and availability of sexual health care. Out of 71 eligible departments, 34 urology and 15 radiotherapy departments participated in the survey (response rate 69.0%). Fifty-nine brochures corresponding to 31 urology and 11 radiotherapy departments were analysed. In 88.1% of collected information material, sexual health was mentioned. Regarding extensiveness, 20.4% of the brochures contained extensive information, 50.8% moderate amount of information and 28.8% contained little or no information. Urology departments provided pre-treatment nurse consultations more often than radiotherapy departments. Sexual counselling was more frequently provided by urology departments. Urology departments were more aware of adequate referral possibilities. Information material provided by Dutch urology and radiotherapy departments does not address treatment-related SD routinely. Sexual health care is not available everywhere for men experiencing SD. Applying a standard regarding content of sexual health in information material is recommended as well as improved awareness of referral possibilities and enhanced provision of pre-treatment nurse consultations for men experiencing SD after prostate cancer treatment. © 2016 John Wiley & Sons Ltd.

    2018-01-01

    Through the widespread availability of location-identifying devices, geolocalisation could potentially be used to place athletes during out-of-competition testing. In light of this debate, the WADA Ethics Panel formulated the following questions: (1) should WADA and/or other sponsors consider funding such geolocalisation research projects?, (2) if successful, could they be proposed to athletes as a complementary device to Anti-Doping Administration and Management System to help geolocalisation and reduce the risk of missed tests? and (3) should such devices be offered on a voluntary basis, or is it conceivable that they would be made mandatory for all athletes in registered testing pools? In this position paper, the WADA Ethics Panel concludes that the use of geolocalisation could be useful in a research setting with the goal of understanding associations between genotype, phenotype and environment; however, it recognises that the use of geolocalisation as part of or as replacement of whereabouts rules is replete with ethical concerns. While benefits remain largely hypothetical and minimal, the potential invasion of privacy and the data security threats are real. Considering the impact on privacy, data security issues, the societal ramifications of offering such services and various pragmatic considerations, the WADA Ethics Panel concludes that at this time, the use of geolocalisation should neither be mandated as a tool for disclosing whereabouts nor implemented on a voluntary basis.

    To measure social network activity during the 81th National Congress of the Spanish Urological Association (AEU) and to compare it with the activity during other congresses of national and international urological associations. We designed and registered the official hashtag #AEU16 for the 81 th National Congress of the AEU on the Symplur website. The following measurements were recorded: number of participants, number of tweets, tweets by participant, tweets per hour and views. The number of participants in the social network activity during the congress was 207. The measurements of activity in Twitter consisted of a total of 1866 tweets, a mean rate of 16 tweets/h, 9 tweets per participant and 1,511,142 views. The activity during the international congresses is as follows: 2016 American Urological Association annual congress (views: 28,052,558), 2016 European Association of Urology annual congress (views: 13,915,994), 2016 Urological Society of Australia and New Zealand (views: 4,757,453), 2015 Société Internationale d'Urologie annual congress (views: 1,023,038).

    To determine the factors related to stress, Burnout and depression in urology, as well as consequences in residents and urologists, in addition to the possible applicable strategies to diminish and treat them. Depression, stress and Burnout syndrome has become a problem in urology specialty. These topics have gained interest in international congresses and urological associations. Efforts are being made to find related factors as well as possible strategies and applicable support programs. Burnout frequency is higher among health professionals than general population, 40-76% in students and residents, its incidence has skyrocketed in recent years, in addition Urology is one of the specialties with highest incidence and severity. Its increase has been related to work overload, documentation, administrative/bureaucratic workload, hostile work environment; its consequences include poor work performance, medical errors, depression, substance abuse, disruption in family and couple relationships and suicidal ideation. Strategies for prevention including resilience training, lifestyle balance, teamwork, and support programs. Stress, burnout and depression are problems in urology, early detection, promoting individual techniques in resilience, lifestyle and teamwork are fundamental now and for the future of the specialty. Developing and implementing support programs should be seriously considered by health systems and urological associations.

    E-learning is a teaching tool used successfully in many medical subspecialties. Experience with its use in urology, however, is scarce. We present our teaching experience with the INMEDEA simulator to teach urological care to medical students. The INMEDEA simulator is an interactive e-learning system built around a virtual hospital which includes a department of urology. It allows students to solve virtual patient cases online. In this study, students were asked to prepare two urological cases prior to discussion of the cases in small groups. This blended teaching approach was evaluated by students through anonymous questionnaires. Of 70 4th year medical students 76% judged this teaching method as good or very good. Eighty-seven percent felt that it offered a good way to understand urological diseases better and 72% felt that learning with this method was fun. Nevertheless, 30 out of 70 free text statements revealed that further improvements of the program, including an easier and more comfortable navigation and a faster supply of information are necessary. Virtual patient cases offer a practicable solution for teaching based on problem solving in urology with a high acceptance rate by students.

    Advances in technology have revolutionized urology. Minimally invasive tools now form the core of the urologist's armamentarium. Laparoscopic surgery has become the favored approach for treating many complicated urologic ailments. Surgical robots represent the next evolutionary step in the fruitful man-machine partnership. The introduction of robotic technology in urology changes how urologists learn, teach, plan, and operate. As technology evolves, robots not only will improve performance in minimally invasive procedures, but also enhance other procedures or enable new kinds of operations.

    Asian scientists have now increasingly begun to contribute to globalization; yet it is not clear whether publishing in the field of urology is paralleled by elevated cross-continental scientific publishing. An exemplary bibliometric analysis of urologic journals from 3 different continents was conducted between 2002 and 2012. Based on the ISI Web of Knowledge Journal Citation Reports, 2 urologic journals with similar impact factors (IFs) in 2013 were selected from Europe ('British Journal of Urology International', 'World Journal of Urology'), Asia ('International Journal of Urology', 'Asian Journal of Andrology') and North America ('Urologic Oncology-Seminars and Original Investigations', 'Urology'). The home continent of the journal, the workplace continental affiliation of the last author, article type (clinical, experimental or review) as well as the IF were documented. Most authors published their manuscripts in journals from the same continent in which they worked. However, a significant increase in cross-continental publishing was apparent from 2002 to 2012. Asians publishing in North America increased from 17% in 2002 to 35% in 2012. Europeans also increased the number of articles they published in North American journals, while publications from North American authors were shifted towards both European and Asian journals. Experimental and clinical articles showed significant increases in cross-continental publishing, while review publishing showed no significant change. The average IF for authors from all 3 continents increased from 2002 to 2012 (p < 0.001). The largest increase in the IF was found for Asian authors (0.11 per year). Cross-continental publication significantly increased during the period from 2002 to 2012. The impact that the Asian authors have experienced was found to be gradually impacting the North American and European colleagues. © 2015 S. Karger AG, Basel.

    We recently reported on preclinical and feasibility studies (Innovation, Development, Exploration, Assessment, Long-term study [IDEAL] phase 0-1) of the development of robotic kidney transplantation (RKT) with regional hypothermia. This paper presents the IDEAL phase 2a studies of technique development. To describe the technique of RKT with regional hypothermia developed at two tertiary care institutions (Vattikuti Urology Institute and Medanta Hospital). We report on the safety profile and early graft function in these patients. This is a prospective study of 50 consecutive patients who underwent live-donor RKT at Medanta Hospital following a 3-yr planning/simulation phase at the Vattikuti Urology Institute. Demographic details, and perioperative and postoperative outcomes are reported for the initial 25 recipients who have completed a minimum 6-mo follow-up. Positioning and port placement were similar to that used for robotic radical prostatectomy. Allograft cooling was achieved by ice slush delivered through a GelPOINT device. The accompanying video details the operative technique. The primary outcome was posttransplant graft function. Secondary outcomes included technical success or failure and complication rates. Fifty patients underwent RKT successfully, 7 in the phase 1 and 43 in the phase 2 stages of the study. For the initial 25 patients, mean console, warm ischemia, arterial, and venous anastomotic times were 135, 2.4, 12, and 13.4 min, respectively. All grafts were cooled to 18-20 °C with no change in core body temperature. All grafts functioned immediately posttransplant and the mean serum creatinine level at discharge was 1.3mg/dl (range: 0.8-3.1mg/dl). No patient developed anastomotic leaks, wound complications, or wound infections. At 6-mo of follow-up, no patient had developed a lymphocele detected on CT scanning. Two patients underwent re-exploration, and one patient died of congestive heart failure (1.5 mo posttransplant). RKT with regional hypothermia is safe and reproducible when performed by a team skilled in robotic surgery. RKT is safe and effective when performed by surgeons experienced in robotic techniques.

    2005-06-28

    A transparent electromagnetic shield to protect solar panels and the like from dust deposition. The shield is a panel of clear non-conducting (dielectric) material with embedded parallel electrodes. The panel is coated with a semiconducting film. Desirably the electrodes are transparent. The electrodes are connected to a single-phase AC signal or to a multi-phase AC signal that produces a travelling electromagnetic wave. The electromagnetic field produced by the electrodes lifts dust particles away from the shield and repels charged particles. Deposited dust particles are removed when the electrodes are activated, regardless of the resistivity of the dust. Electrostatic charges on the panel are discharged by the semiconducting film. When used in conjunction with photovoltaic cells, the power for the device may be obtained from the cells themselves. For other surfaces, such as windshields, optical windows and the like, the power must be derived from an external source. One embodiment of the invention employs monitoring and detection devices to determine when the level of obscuration of the screen by dust has reached a threshold level requiring activation of the dust removal feature.

    Although the artificial urinary sphincter (AUS) is one of the most effective surgical treatments for severe urinary incontinence, little is known about its use in Japan. A nationwide survey was done to determine contemporary trends in AUS use and its long-term durability. Data on AUS units sold in Japan were provided directly by Takai Hospital Supply Co., Ltd., Tokyo, Japan, and a survey form was sent to all 44 institutes where AUS implantation had been carried out. The survey included various demographic and preoperative variables, surgical variables, and postoperative outcomes. Between 1994 and 2007, a total of 100 AUS devices had been provided in Japan. Of the 44 institutes, 24 responded to the survey, and a total of 64 patients were enrolled in the study. Post-urological surgery incontinence accounted for 81.3% of the indications. During the mean follow-up of 50 months, mechanical failure occurred in four (6.2%), and the device was removed in 13 (20.3%) due to infection (14.0%), erosion (4.7%), or urination difficulty (1.5%). Of the 58 patients evaluated, 91.4% reported social continence. Five- and 10-year failure-free rates were 74.8% and 70.1%, respectively. On multivariate analysis, operative time was an independent predictor of treatment failure (P = 0.0334). Considering recent trends in prostate surgery, the AUS may be significantly underused in Japan. Although excellent long-term durability has been achieved, a learning effect appears to be evident. The Japanese urological community needs to provide appropriate patients with this treatment option.

    Much has been written on the treatment of solitary or multiple metastatic nodules that sometimes present in patients with urological malignancies. However, relatively little has been published regarding those patients with urological cancer who have another concomitant primary non-urologic tumor. We describe several cases of patients who presented with a urologic malignancy and a secondary non-urologic tumor. We also reviewed the literature using MEDLINE to gather information concerning this rare occurrence. We found that secondary malignancies, although not very common, are being increasingly reported. They are usually detected during the preoperative work-up of the primary tumor, usually by CT scan, ultrasound, or chest X-ray. Most authors suggest that treatment should be directed at the more aggressive lesion first, which would improve the overall status of the patient, and thus allow a better response from therapy for the secondary lesion. While patients with multiple primary malignancies are rare, the urologist should be alerted to this possibility when evaluating the patient for the initially presenting or detected tumor.

    The aim of our study was to determine the contemporary practice in the utilization of life expectancy (LE) calculations among urological clinicians. Members of the Irish Society of Urology (ISU) and the British Association of Urological Surgeons (BAUS) completed a questionnaire on LE utilization in urological practice. The survey was delivered to 1251 clinicians and the response rate was 17% (n = 208/1251). The majority (61%, n = 127) of urologists were aware of methods available for estimated LE calculation.Seventy-one percent (n = 148) had never utilized LE analysis in clinical practice and 81% (n = 170) routinely used 'eyeballing' (empiric prediction) for estimating LE. Life expectancy tables were utilized infrequently (12%, n = 25) in making the decision for treatment in the setting of multi-disciplinary meetings. LE is poorly integrated into treatment decision-making; not only for the management of urological patients but also in the multidisciplinary setting. Further education and awareness regarding the importance of LE is vital.

    Management of men with penile squamous cell carcinoma (PSCC) who have high-risk features following radical inguinal lymphadenectomy (ILND) remains controversial. European Association of Urology guidelines state that adjuvant inguinal radiotherapy (AIRT) is "not generally recommended". Despite this, many centres continue to offer AIRT to a subset of men. To undertake a systematic review of the evidence on AIRT in node-positive men with PSCC. A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, with no language or date restriction. Inclusion criteria were men with PSCC, pathologically staged inguinal node positive after ILND. The intervention included ILND with AIRT compared with ILND alone. Primary outcomes were relapse-free survival and toxicity. Risk of bias assessment was undertaken. A total of 913 abstracts were identified and screened independently by two reviewers. Seven studies were eligible for inclusion: six full-text manuscripts and one conference abstract. All were retrospective series and at a high risk of bias. The selected studies included 1605 men. Indications for AIRT varied but were typically involvement of two or more inguinal nodes or extranodal extension. Regional recurrence rate following AIRT was reported at 10-91.7%. Only one study reported on toxicity. Two studies compared recurrence and survival between men who received and who did not receive AIRT, with no significant difference (p>0.05). The evidence indicates that men treated with AIRT do not gain benefit with respect to relapse or survival. Uncertainty remains due to the retrospective nature and high risks of bias across the evidence. Given the lack of evidence supporting AIRT, it cannot be recommended for routine practice. Men with penile cancer who have involvement of the inguinal lymph nodes are at a high risk of cancer recurrence and death. We reviewed the literature to see if radiation treatment after removal of the nodes provided benefit. We did not find any good-quality evidence supporting this treatment, and hence it cannot be recommended. Copyright © 2018 European Association of Urology. Published by Elsevier B.V.

    Tumour grade is an important prognostic indicator in non-muscle-invasive bladder cancer (NMIBC). Histopathological classifications are limited by interobserver variability (reproducibility), which may have prognostic implications. European Association of Urology NMIBC guidelines suggest concurrent use of both 1973 and 2004/2016 World Health Organization (WHO) classifications. To compare the prognostic performance and reproducibility of the 1973 and 2004/2016 WHO grading systems for NMIBC. A systematic literature search was undertaken incorporating Medline, Embase, and the Cochrane Library. Studies were critically appraised for risk of bias (QUIPS). For prognosis, the primary outcome was progression to muscle-invasive or metastatic disease. Secondary outcomes were disease recurrence, and overall and cancer-specific survival. For reproducibility, the primary outcome was interobserver variability between pathologists. Secondary outcome was intraobserver variability (repeatability) by the same pathologist. Of 3593 articles identified, 20 were included in the prognostic review; three were eligible for the reproducibility review. Increasing tumour grade in both classifications was associated with higher disease progression and recurrence rates. Progression rates in grade 1 patients were similar to those in low-grade patients; progression rates in grade 3 patients were higher than those in high-grade patients. Survival data were limited. Reproducibility of the 2004/2016 system was marginally better than that of the 1973 system. Two studies on repeatability showed conflicting results. Most studies had a moderate to high risk of bias. Current grading classifications in NMIBC are suboptimal. The 1973 system identifies more aggressive tumours. Intra- and interobserver variability was slightly less in the 2004/2016 classification. We could not confirm that the 2004/2016 classification outperforms the 1973 classification in prediction of recurrence and progression. This article summarises the utility of two different grading systems for non-muscle-invasive bladder cancer. Both systems predict progression and recurrence, although pathologists vary in their reporting; suggestions for further improvements are made. Copyright © 2017 European Association of Urology.

    The urinary tract, previously considered a sterile body niche, has emerged as the host of an array of bacteria in healthy individuals, revolutionizing the urology research field. To review the literature on microbiome implications in the urinary tract and the usefulness of probiotics/prebiotics and diet as treatment for urologic disorders. A systematic review was conducted using PubMed and Medline from inception until July 2016. The initial search identified 1419 studies and 89 were included in this systematic review. Specific bacterial communities have been found in the healthy urinary tract. Changes in this microbiome have been observed in certain urologic disorders such as urinary incontinence, urologic cancers, interstitial cystitis, neurogenic bladder dysfunction, sexually transmitted infections, and chronic prostatitis/chronic pelvic pain syndrome. The role of probiotics, prebiotics, and diet as treatment or preventive agents for urologic disorders requires further investigation. There is a microbiome associated with the healthy urinary tract that can change in urologic disorders. This represents a propitious context to identify new diagnostic, prognostic, and predictive microbiome-based biomarkers that could be used in clinical urology practice. In addition, probiotics, prebiotics, and diet modifications appear to represent an opportunity to regulate the urinary microbiome. We review the urinary microbiome of healthy individuals and its changes in relation to urinary disorders. The question to resolve is how we can modulate the microbiome to improve urinary tract health. Copyright © 2016 European Association of Urology. Published by Elsevier B.V. All rights reserved.

    The German DRG (dose-related groups) system is updated each year by the institution dealing with the remuneration in hospitals (InEK). Once again, the German Spcoety for Urology has supported the adjustment process in a constructive manner. Analysis of the changes and their implications is highly significant for urology. This article describes and discusses the main changes in the system for the specialty of urology insofar as they concern the structure of the DRG system and the catalogues of diagnoses (ICD) and of procedures (OPS). The 2007 edition of the DRG system leads to numerous changes for urology. There are new OPS codes for partial resection of the kidney, treatment of urinary incontinence and radical resection in the pelvis minor. Additional payment for implantation of a prosthetic penis is divided with reference to the type of prosthesis. At DRG level, new DRG splits are found depending on the PCCL and patient age. Combination operations on the bladder and bowel and on the male genitalia are assigned to newly established DRGs. The changes described enhance the professional accuracy of the representations of urological care provision. New strategies designed to solve problems in representation have been established (e.g. multi-step interventions). Various problems persist, e.g. those of operations on the penis (DRG M03Z) and the need for more finely defined representation of laser treatment in urology. In the short term practicable solutions to the problem of improving the quality of representation are needed.

    The study focus is on the quantitative achievements in urology education and growth trends in urologic surgical workforce and fellowships by gender since 1979. This comprehensive national quantitative study was performed in Iranian Academy of medical science. The first hand data gathered from The Iran Specialty Training Council of and also from Medical Council of Iran. Over the period 1979 to 2012, the numbers of resident's admission in urology/ fellowships have increased from 5 to 51 and from 0 to 24 respectively, and graduated urologists of national programs has grown from 5 (14%) in 1979 to 47 (100%) in 2012. Iranian urologists workforce haves increased from 315 in 1979 to 1637 in 2012. In 1979, there was 1 urologist for every 117,460 population, while in 2012 there was 1 urologist for every 46120 population. Iran Urologists to population rate is 1:46120. These statistics represents significant improvement from 34 years ago. Number of female urologists has progressively increased from 1 in 1979 (0%) to 110 (7%) in 2012. Urology fellowships are offered in 6 fields since 1994 in Iran. The number of trained fellowships grew sharply and reached to 221 in 2012. The current urology training is successful to improve urology health care. Along with expansion of urology and fellowship training, the number of Iranian female urologists significantly increased. To our knowledge Iran had the greatest growth rate of female urologist training in the Middle East, and is comparable with those in the most progressed countries in the world.

    Urological and sexual dysfunction are recognised risks of rectal cancer surgery; however, there is limited evidence regarding urogenital function comparing robotic to laparoscopic techniques. The aim of this study was to assess the urogenital functional outcomes of patients undergoing laparoscopic and robotic rectal cancer surgery. Urological and sexual functions were assessed using gender-specific validated standardised questionnaires. Questionnaires were sent a minimum of 6 months after surgery, and patients were asked to report their urogenital function pre- and post-operatively, allowing changes in urogenital function to be identified. Questionnaires were sent to 158 patients (89 laparoscopy, 69 robotic) of whom 126 (80 %) responded. Seventy-eight (49 male, 29 female) of the responders underwent laparoscopic and 48 (35 male, 13 female) robotic surgery. Male patients in the robotic group deteriorated less across all components of sexual function and in five components of urological function. Composite male urological and sexual function score changes from baseline were better in the robotic cohort (p < 0.001). In females, there was no difference between the two groups in any of the components of urological or sexual function. However, composite female urological function score change from baseline was better in the robotic group (p = 0.003). Robotic rectal cancer surgery might offer better post-operative urological and sexual outcomes compared to laparoscopic surgery in male patients and better urological outcomes in females. Larger scale, prospective randomised control studies including urodynamic assessment of urogenital function are required to validate these results.

    This paper presents an improved generalized physical model for photovoltaic, PV cells, panels and arrays taking into account the behavior of these devices when considering their biasing existing in direct and reverse modes. Existing PV physical models generally are very efficient for simulating influence of irradiation changes on the short circuit current but they could not visualize the influences of temperature changes. The Enhanced Direct and Reverse Mode model, named EDRM model, enlightens the influence on the short-circuit current of both temperature and irradiation in the reverse mode of the considered PV devices. Due to its easy implementation, the proposed model can be a useful power tool for the development of new photovoltaic systems taking into account and in a more exhaustive manner, environmental conditions. The developed model was tested on a marketed PV panel and it gives a satisfactory results compared with parameters given in the manufacturer datasheet.

  9. Harvesting biomechanical energy or carrying batteries? An evaluation method based on a comparison of metabolic power.

    Harvesting energy from human motion is an innovative alternative to using batteries as a source of electrical power for portable devices. Yet there are no guidelines as to whether energy harvesting should be preferred over batteries. This paper introduces an approach to determine which source of energy should be preferred. The proposed approach compares the metabolic power while harvesting energy and while using batteries (or any other power supply, e.g., solar panels), which provide equal amount of energy. Energy harvesting is preferred over batteries if the metabolic power required to harvest the energy is lower than that required to carry the batteries. Metabolic power can be experimentally measured. However, for design purposes, it is essential to assess differences in metabolic power as a function of the device parameters. To this end, based on the proposed approach, we develop a mathematical model that considers the following parameters: the device's mass, its location on the human body, the electrical power output, cost of harvesting (COH), walking time, and the specific energy of the battery. We apply the model in two ways. First, we conduct case studies to examine current ankle, knee, and back energy harvesting devices, and assess the walking times that would make these devices preferable over batteries. Second, we conduct a design scenarios analysis, which examines future device developments. The case studies reveal that to be preferred over batteries, current harvesting devices located on the ankle, knee, or back would require walking for 227 hours, 98 hours, or 260 hours, respectively. This would replace batteries weighing 6.81 kg (ankle), 5.88 kg (knee), or 2.6 kg (back). The design scenarios analysis suggests that for harvesting devices to be beneficial with less than 25 walking hours, future development should focus on light harvesting devices (less than 0.2 kg) with low COH (equal or lower than 0). Finally, a comparison with portable commercial solar panels reveals that under ideal sun exposure conditions, solar panels outperform the current harvesting devices. Our model offers a tool for assessing the performance of energy harvesting devices.

    In this work is presented the development of a mechatronics device to simulate the interaction of the surgeon with the surgical instrument (resectoscope) used during a Transurethral Resection of the Prostate (TURP). Our mechatronics interface is part of a computer assisted system for training in TURP, which is based on a 3D graphics model of the prostate which can be deformed and resected interactively by the user. The mechatronics interface, is the device that the urology residents will manipulate to simulate the movements performed during surgery. Our current prototype has five degrees of freedom, which are enough to have a realistic simulation of the surgery movements. Two of these degrees of freedom are linear, to determinate the linear displacement of the resecting loop and the other three are rotational to determinate three directions and amounts of rotation.

    During 26 months 200 consecutive patients with fracture of the bony pelvis were evaluated and treated for urological injury. There was no correlation between the extent of pelvic injury and degree of hematuria but hematuria was present in all patients with a urological injury. All urological injuries occurred with anterior arch fractures. The over-all incidence of injury was 13.5 per cent (bladder 9 per cent, urethra 3.5 per cent and combined 1 per cent). Limited extraperitoneal bladder ruptures were treated successfully by Foley catheter drainage.

    Robotic surgery was initially developed to overcome problems faced during conventional laparoscopic surgeries and to perform telesurgery at distant locations. It has now established itself as the epitome of minimally invasive surgery (MIS). It is one of the most significant advances in MIS in recent years and is considered by many as a revolutionary technology, capable of influencing the future of surgery. After its introduction to urology, robotic surgery has redefined the management of urological malignancies. It promises to make difficult urological surgeries easier, safer and more acceptable to both the surgeon and the patient. Robotic surgery is slowly, but surely establishing itself in India. In this article, we provide an overview of the advantages, disadvantages, current status, and future applications of robotic surgery for urologic cancers in the context of the Indian scenario.

    Rapid technological developments in the past two decades have produced new inventions such as robots and incorporated them into our daily lives. Today, robots perform vital functions in homes, outer space, hospitals and on military instillations. The development of robotic surgery has given hospitals and health care providers a valuable tool that is making a profound impact on highly technical surgical procedures. The field of urology is one area of medicine that has adopted and incorporated robotic surgery into its armamentarium. Innovative robotic urologic surgical applications and techniques are being developed and reported everyday. Increased utilization and development will ultimately fuel the discovery of newer applications of robotic systems in urologic surgery. Herein we provide an overview of the history, development, and applications of robotics in surgery with a focus on urologic surgery.

    Applicant interviews for urology residency positions are a stressful and costly process for students, faculty, and staff. We conducted a prospective survey to better determine what urology applicants perceive as an ideal interview process to gain sufficient knowledge about a training program. A questionnaire was anonymously completed by all urology residency applicants interviewing at the Medical College of Wisconsin from 2007 to 2013. Questionnaire subject headings included "ideal interview format," "factors contributing to understanding the residency program," and "factors contributing to final rank list order." Questionnaires were distributed to and completed by 221 senior medical students applying for a urology residency position. Most respondents (>80%) reported they would prefer to partake in 5 to 7 faculty interviews in an office setting with the total interview process spanning half to three-fourths of the workday. Spending time with current residents was considered the most valuable tool to acquire knowledge about a residency program. The most important criteria when ranking a program were resident satisfaction, resident operative experience, and perceived strength of faculty. Academic urology programs may wish to consider applicant ideals when organizing residency interviews. Interaction with current residents appears to be the most valuable resource allowing applicants to garner knowledge about a urology training program.

    To retrospectively review recent publications describing novel procedures/techniques, and describe the Institutional Review Board (IRB)/ethics approval process and potential ethical dilemmas in their reporting. We searched PubMed for papers about innovative or novel procedures/techniques between 2011 and August 2012. A query of titles/abstracts in the Journal of Urology, Journal of Endourology, European Urology, BJU International, and Urology identified relevant papers. These results were reviewed for human studies that described an innovative technique, procedure, approach, initial series, and/or used new technology. In all, 91 papers met criteria for inclusion; 25 from the Journal of Endourology, 14 from the Journal of Urology, nine from European Urology, 15 from the BJU International and 28 from Urology. IRB/ethics approval was given for an experimental procedure or database in 24% and 22%, respectively. IRB/ethics approval was not mentioned in 52.7% of studies. Published IRB/ethics approvals for innovative techniques are heterogeneous including database, retrospective, and prospective approvals. Given the concept that innovations are likely not in the legal or ethical standard of care, strong consideration should be given to obtaining IRB/ethics approval before the actual procedure, instead of approval to merely report database outcomes. © 2013 The Authors.

    We conducted an extensive search to learn more about Ramon Guiteras, the founder of the American Urological Association. Scientific publications, newspaper articles, and historical documents and texts were reviewed. Institutions and organizations of which Ramon Guiteras was a member were contacted. Guiteras' career peaked at the turn of the century, just as genitourinary surgery was emerging as an independent field. The American Urological Association began as an organization of the members of Guiteras' clinic with the dream of becoming an inclusive organization for the benefit of all ethical physicians with an interest in the urinary sciences. Guiteras contributed to advances in urological treatments, including improving and helping to bring a method of suprapubic prostatectomy to worldwide attention. He authored numerous scientific articles and a comprehensive, fully illustrated, 2-volume textbook that was widely translated. He pursued adventure through travel and sport, and participated in missions to Cuba and France during President Wilson's term of office. Ramon Guiteras died at age 59 years but his legacy lives on through the American Urological Association, a detailed textbook, contributions to urological instruments and techniques, and a vibrant elementary school in Bristol, Rhode Island that bears his name.

    Personal computers may be used to create, store, and deliver graphical presentations. With computer-generated combinations of the five media (text, images, sound, video, and animation)--that is, multimedia presentations--the effectiveness of message delivery can be greatly increased. The basic tools are (1) a personal computer; (2) presentation software; and (3) a projector to enlarge the monitor images for audience viewing. Use of this new method has grown rapidly in the business-conference world, but has yet to gain widespread acceptance at medical meetings. We review herein the rationale for multimedia presentations in medicine (vis-à-vis traditional slide shows) as an improved means for increasing audience attention, comprehension, and retention. The evolution of multimedia is traced from earliest times to the present. The steps involved in making a multimedia presentation are summarized, emphasizing advances in technology that bring the new method within practical reach of busy physicians. Specific attention is given to software, digital image processing, storage devices, and delivery methods. Our development of a urology multimedia presentation--delivered May 4, 1996, before the Society for Urology and Engineering and now Internet-accessible at http://www.usrf.org--was the impetus for this work.

    This paper describes the handling evaluation (by a group of practice-based researchers, the PREP Panel) of a recently introduced Light Curing Unit (LCU), the Kerr Demi-Ultra, which possesses a number of novel features such as its ultracapacitor power source, and the Light Emitting Diodes (LEDs) which provide the light output being placed close to the tip of the light guide. CPD/CLINICAL RELEVANCE: Testing of new devices and materials with respect to their handling is of importance, given that an easy to handle device should produce better clinical results than one which is difficult to use.

    We used next-generation, state-of-the-art, culture independent methodology to survey urine microbiota of males with urologic chronic pelvic pain syndrome and control participants enrolled in the MAPP Network to investigate a possible microbial etiology. Male patients with urologic chronic pelvic pain syndrome and matched controls were asked to provide initial, midstream and post-prostatic massage urine specimens. Specimens were analyzed with Ibis T-5000 Universal Biosensor technology to provide comprehensive identification of bacterial and select fungal species. Differences between urologic chronic pelvic pain syndrome and control study participants for the presence of species or species variation in a higher taxonomic grouping (genus) were evaluated using permutational multivariate analysis of variance and logistic regression. Initial and midstream urine specimens were obtained from 110 (post-prostatic massage urine in 67) participants with urologic chronic pelvic pain syndrome and 115 (post-prostatic massage urine in 62) controls. Overall 78, 73 and 54 species (42, 39 and 27 genera) were detected in initial, midstream and post-prostatic massage urine specimens, respectively. Mean (SD) initial, midstream and post-prostatic massage urine species count per person was 1.62 (1.28), 1.38 (1.36) and 1.33 (1.24) for cases, and 1.75 (1.32), 1.23 (1.15) and 1.56 (0.97) for controls, respectively. Overall species and genus composition differed significantly between participants with urologic chronic pelvic pain syndrome and controls in initial stream urine (p=0.002 species level, p=0.004 genus level), with Burkholderia cenocepacia overrepresented in urologic chronic pelvic pain syndrome. No significant differences were observed at any level in midstream or post-prostatic massage urine samples. Assessment of baseline culture-independent microbiological data from male subjects enrolled in the MAPP Network has identified overrepresentation of B. cenocepacia in urologic chronic pelvic pain syndrome. Future studies are planned to further evaluate microbiota associations with variable and changing urologic chronic pelvic pain syndrome symptom patterns.

    The Nd:YAG laser has become a coagulation instrument, which has found acceptance in interdisciplinary surgery. The main contributors are its highly efficient coagulation capability in interaction with tissue and the fact that the Nd:YAG laser beam can be transmitted by means of a simple quartz-glass fiber. Appropriate systems and instruments for transmission and operation have been developed for the various applications in neurosurgery, pulmology, gastroenterology, urology, gynaecology and dermatology. Operation methods in open and endoscopic surgery under use of several hand held devices and flexible as well as rigid endoscopes are being demonstrated by clinical examples of application.

  6. The unusual history and the urological applications of botulinum neurotoxin.

    2010-01-01

    Botulinum neurotoxin (BoNT) is probably the most potent biological toxin that can affect humans. Since its discovery by Justinus Kerner, BoNT has seen use in a wide range of cosmetic and non-cosmetic conditions such as cervical dystonia, cerebral palsy, migraines and hyperhidrosis. We tried to trace its history from its inception to its recent urological applications. Historical articles about botulinum toxin were reviewed and a Medline search was performed for its urological utility. We hereby present a brief review of historical aspects of BoNT and its applications in urology. In 1793, the first known outbreak of botulism occurred due to 'spoiled' sausage in Wildebad, Germany. The German physician and poet Justinus Kerner published the first accurate description of the clinical symptoms of botulism (sausage poison). He was also the first to mention its potential therapeutic applications. In urology, BoNT has been used in bladder and urethral lesions with varying degree of success. Recently, BoNT applications were explained for prostatic disorders. BoNT applications in urology are in the treatment of detrusor external sphincter dyssynergia, detrusor overactivity, detrusor underactivity, spastic conditions of the urethral sphincter, chronic prostate pain, interstitial cystitis, non-fibrotic bladder outflow obstruction (including benign prostatic hyperplasia) and acute urinary retention in women. Justinus Kerner is the godfather of botulism research. The role of BoNT in urology has evolved exponentially and it is widely used as an adjuvant in voiding dysfunction. In the future, its utility will broaden and guide the urologist in managing various urological disorders. Copyright © 2010 S. Karger AG, Basel.

    2016-07-01

    In recent years the regional aspects of medical history in the field of urology have been more intensively studied. There is already an interesting study on the history of urology in Rhineland. This article examines the checkered medical history aspects concerning urology in provincial areas of Germany, exemplified by the Bavarian town of Regensburg. The article combines the history of the over 1800-year-old town of Regensburg, one of the oldest German communities, with selected aspects of medical history and follows the route of "stones" from antiquity to the present day. The article explains what Regensburg, Galen of Pergamon and his professional colleagues from antiquity have in common, why monastery medicine was so successful here, how syphilis patients were treated in imperial cities (Reichsstädte), why one of the greatest "stone cutters" of the era met with an accident in the perpetual Reichstag town of Regensburg and how a main department of urology was finally founded after a delay but ultimately with tempo, which in 2003 led to the establishment of the most recent chair for urology in Germany.

    Urologic cancers are not only among the most common types of cancers, but also among the most expensive cancers to treat in the United States. This study aimed to review the use of CEAs and other cost analyses in urologic oncology using large databases to better understand the value of management strategies of these cancers. A literature review on CEAs and other cost analyses in urologic oncology using large databases. The options for and costs of diagnosing, treating, and following patients with urologic cancers can be expected to rise in the coming years. There are numerous opportunities in each urologic cancer to use CEAs to both lower costs and provide high-quality services. Improved cancer care must balance the integration of novelty with ensuring reasonable costs to patients and the health care system. With the increasing focus cost containment, appreciating the value of competing strategies in caring for our patients is pivotal. Leveraging methods such as CEAs and harnessing large databases may help evaluate the merit of established or emerging strategies. Copyright © 2018 Elsevier Inc. All rights reserved.

    Written responses from American trained women in urological surgery were obtained to evaluate practice patterns, career choices and workplace satisfaction. A 3-page unblinded questionnaire was mailed in March 2003 to American trained women in urological surgery available through the databases of the Society of Women in Urology with subsequent statistical analysis. The response rate was 60% but inclusive of all women in current academic practice in the United States. A total of 61% reported working 51 or more hours a week whereas 2% have left practice due to retirement or medical infirmity. There were 41% who had completed fellowships including 87% reporting active practice within their subspecialty, whereas 62% of fellowship trained surgeons remained in an academic practice. Among United States women in academic urological practice, academic progression has occurred in a third of this cohort. Threats to successful practice, consistent with other workplace surveys of physicians and professional women including gender based role limitation and inadequate mentoring, were commonly reported. These correctable workplace deficiencies represent an opportunity for American urology to enhance the professional workplace for all urologists regardless of gender.

    The National Institutes of Health, American Medical Association, and United States Department of Health and Human Services recommend that patient education materials be written at a fourth to sixth grade reading level to facilitate comprehension. We examined and compared the readability and difficulty of online patient education materials from the American Urological Association and academic urology departments in the Northeastern United States. We assessed the online patient education materials for difficulty level with 10 commonly used readability assessment tools, including the Flesch Reading Ease Score, Flesch-Kincaid Grade Level, Simple Measure of Gobbledygook, Gunning Frequency of Gobbledygook, New Dale-Chall Test, Coleman-Liau index, New Fog Count, Raygor Readability Estimate, FORCAST test and Fry score. Most patient education materials on the websites of these programs were written at or above the eleventh grade reading level. Urological online patient education materials are written above the recommended reading level. They may need to be simplified to facilitate better patient understanding of urological topics.

    To review the biography and scientific contributions of Dr. Angel Pulido Martin, fourth chairman of the Department of Urology at the Hospital Provincial of Madrid, and formerly at the Urology Clinic at the San Juan de Dios Hospital of Madrid. In addition, to show a panoramic view on how doctors who obtained scholarships to study outside Spain were trained in a specialty at the beginning of the 20th century. We reviewed memoirs books from Dr. Pulido Martin ("Medical letters", "Dr. Pulido and his time", and "Memoirs of a doctor"), his Ph.D. thesis and other works. We also reviewed biographic data obtained from his contemporaries in different publications. We report his experiences as a student in the specialities of Urology and Gynecology, since he first thought about taking this last one. Main european urologic and gynecologic centers of that time are represented, as well as some of the main characters in these specialties. We appreciate his great working spirit, which was inculcated into him by his father Dr. Pulido Fernandez, his enterprising desire, and the great professional he was, creating departments of urology which were school and model for many urologists of his time. A sincere clinician, Dr. Pulido Martin liked accuracy and daily self-improvement. He also was exceptional for his kindness treating patients and disciples. His publications on urologic topics were numerous; he also was fluent and entertaining as a non medical writer. He was an outstanding urologist in the early 20th century; he was member of the committee which elaborated the statutes of the Spanish Society of Urology, in which he was President for 11 years. He was also one of the founding members of the International Society of Urology and delegate of its Spanish chapter. He was official lecturer in several meetings, and also member of the Spanish Academy of Medicine and Surgery.

    Simulation based team training provides an opportunity to develop interdisciplinary communication skills and address potential medical errors in a high fidelity, low stakes environment. We evaluated the implementation of a novel simulation based team training scenario and assessed the technical and nontechnical performance of urology and anesthesiology residents. Urology residents were randomly paired with anesthesiology residents to participate in a simulation based team training scenario involving the management of 2 scripted critical events during laparoscopic radical nephrectomy, including the vasovagal response to pneumoperitoneum and renal vein injury during hilar dissection. A novel kidney surgical model and a high fidelity mannequin simulator were used for the simulation. A debriefing session followed each simulation based team training scenario. Assessments of technical and nontechnical performance were made using task specific checklists and global rating scales. A total of 16 residents participated, of whom 94% rated the simulation based team training scenario as useful for communication skill training. Also, 88% of urology residents believed that the kidney surgical model was useful for technical skill training. Urology resident training level correlated with technical performance (p=0.004) and blood loss during renal vein injury management (p=0.022) but not with nontechnical performance. Anesthesia resident training level correlated with nontechnical performance (p=0.036). Urology residents consistently rated themselves higher on nontechnical performance than did faculty (p=0.033). Anesthesia residents did not differ in the self-assessment of nontechnical performance compared to faculty assessments. Residents rated the simulation based team training scenario as useful for interdisciplinary communication skill training. Urology resident training level correlated with technical performance but not with nontechnical performance. Urology residents consistently overestimated their nontechnical performance.

    What's known on the subject? and What does the study add? The role of surgical simulators is currently being debated in urological and other surgical specialties. Simulators are not presently implemented in the UK urology training curriculum. The availability of simulators and the opinions of Training Programme Directors' (TPD) on their role have not been described. In the present questionnaire-based survey, the trainees of most, but not all, UK TPDs had access to laparoscopic simulators, and that all responding TPDs thought that simulators improved laparoscopic training. We hope that the present study will be a positive step towards making an agreement to formally introduce simulators into the UK urology training curriculum. To discuss the current situation on the use of simulators in surgical training. To determine the views of UK Urology Training Programme Directors (TPDs) on the availability and use of simulators in Urology at present, and to discuss the role that simulators may have in future training. An online-questionnaire survey was distributed to all UK Urology TPDs. In all, 16 of 21 TPDs responded. All 16 thought that laparoscopic simulators improved the quality of laparoscopic training. The trainees of 13 TPDs had access to a laparoscopic simulator (either in their own hospital or another hospital in the deanery). Most TPDs thought that trainees should use simulators in their free time, in quiet time during work hours, or in teaching sessions (rather than incorporated into the weekly timetable). We feel that the current apprentice-style method of training in urological surgery is out-dated. We think that all TPDs and trainees should have access to a simulator, and that a formal competency based simulation training programme should be incorporated into the urology training curriculum, with trainees reaching a minimum proficiency on a simulator before undertaking surgical procedures. © 2012 THE AUTHORS.

    We used MAPP data to identify participants with urological chronic pelvic pain syndromes only or a chronic functional nonurological associated somatic syndrome in addition to urological chronic pelvic pain syndromes. We characterized these 2 subgroups and explored them using 3 criteria, including 1) MAPP eligibility criteria, 2) self-reported medical history or 3) RICE criteria. Self-reported cross-sectional data were collected on men and women with urological chronic pelvic pain syndromes, including predominant symptoms, symptom duration and severity, nonurological associated somatic syndrome symptoms and psychosocial factors. Of 424 participants with urological chronic pelvic pain syndromes 162 (38%) had a nonurological associated somatic syndrome, including irritable bowel syndrome in 93 (22%), fibromyalgia in 15 (4%), chronic fatigue syndrome in 13 (3%) and multiple syndromes in 41 (10%). Of 233 females 103 (44%) had a nonurological associated somatic syndrome compared to 59 of 191 males (31%) (p = 0.006). Participants with a nonurological associated somatic syndrome had more severe urological symptoms and more frequent depression and anxiety. Of 424 participants 228 (54%) met RICE criteria. Of 228 RICE positive participants 108 (47%) had a nonurological associated somatic syndrome compared to 54 of 203 RICE negative patients (28%) with a nonurological associated somatic syndrome (p < 0.001). Nonurological associated somatic syndromes represent important clinical characteristics of urological chronic pelvic pain syndromes. Participants with a nonurological associated somatic syndrome have more severe symptoms, longer duration and higher rates of depression and anxiety. RICE positive patients are more likely to have a nonurological associated somatic syndrome and more severe symptoms. Because nonurological associated somatic syndromes are more common in women, future studies must account for this potential confounding factor in urological chronic pelvic pain syndromes.

    The practice of medical and surgical measures in the management of urological ailments prevailed in ancient India from the Vedic era around 3000 BC. Subsequently in the Samhita period, the two stalwarts - Charaka in medicine and Susruta in surgery elevated the art of medicine in India to unprecedented heights. Their elaboration of the etiopathological hypothesis and the medical and surgical treatments of various urological disorders of unparalleled ingenuity still remain valid to some extent in our contemporary understanding. The new generation of accomplished Indian urologists should humbly venerate the legacy of the illustrious pioneers in urology of our motherland. PMID:19675749

    The life of Lord Moynihan is briefly reviewed. Incidence of stones in Peninsular Malaysia appears to show the same trend as in other industrialised countries. Management of urinary calculi both prior to and after the introduction of ESWL in a personal series is discussed. More than 90% of urinary stones are now treated by ESWL threatening the place of surgery in Urology. The pattern of incorporating renal transplantation into the urological training programme as practised in the Institute of Urology and Nephrology in Malaysia is suggested as a way to assure a place for surgery in Urology.

    Urinary tract infection (UTI) is common in young children and may cause pyelonephritis and renal scarring. Long-term complications from renal scarring are low. The role of imaging is to evaluate for underlying urologic abnormalities and guide treatment. In neonates there is increased risk for underlying urologic abnormalities. Evaluation for vesicoureteral reflux (VUR) may be appropriate especially in boys because of higher prevalence of VUR and to exclude posterior urethral valve. In children older than 2 months with first episode of uncomplicated UTI, there is no clear benefit of prophylactic antibiotic. Ultrasound is the only study that is usually appropriate. After the age of 6 years, UTIs are infrequent. There is no need for routine imaging as VUR is less common. In children with recurrent or complicated UTI, in addition to ultrasound, imaging of VUR is usually appropriate. Renal cortical scintigraphy may be appropriate in children with VUR, as renal scarring may support surgical intervention. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. Copyright © 2017 American College of Radiology.

    ABSTRACT Introduction As urology training shifts toward competency-based frameworks, the need for tools for high stakes assessment of trainees is crucial. Validated assessment metrics are lacking for many robot-assisted radical prostatectomy (RARP). As it is quickly becoming the gold standard for treatment of localized prostate cancer, the development and validation of a RARP assessment tool for training is timely. Materials and methods We recruited 13 expert RARP surgeons from the United States and Canada to serve as our Delphi panel. Using an initial inventory developed via a modified Delphi process with urology residents, fellows, and staff at our institution, panelists iteratively rated each step and sub-step on a 5-point Likert scale of agreement for inclusion in the final assessment tool. Qualitative feedback was elicited for each item to determine proper step placement, wording, and suggestions. Results Panelist’s responses were compiled and the inventory was edited through three iterations, after which 100% consensus was achieved. The initial inventory steps were decreased by 13% and a skip pattern was incorporated. The final RARP stepwise inventory was comprised of 13 critical steps with 52 sub-steps. There was no attrition throughout the Delphi process. Conclusions Our Delphi study resulted in a comprehensive inventory of intraoperative RARP steps with excellent consensus. This final inventory will be used to develop a valid and psychometrically sound intraoperative assessment tool for use during RARP training and evaluation, with the aim of increasing competency of all trainees.

    In the second part of this paper, concerning the use of invisible near infrared light (NIR) fluorescence with indocyanine green (ICG) and methylene blue (MB) in urology, other possible uses of this new technique will be presented. In kidney transplantation, this concerns allograft perfusion and real time NIR-guided angiography; moreover, perfusion angiography of tissue flaps, NIRF visualization of ureters, NIR-guided visualization of urinary calcifications, NIRF in male infertility and semen quality assessment. In this part, we have also analysed cancer targeting and imaging fluorophores as well as cost benefits associated with the use of these new techniques. PubMed and Medline databases were searched for ICG and MB use in urological settings, along with data published in abstracts of urological conferences. Although NIR-guided ICG and MB are still in their initial phases, there have been significant developments in a few more major domains of urology, including 1) kidney transplantation: kidney allograft perfusion and vessel reconstruction; 2) angiography perfusion of tissue flaps; 3) visualization of ureters; 4) visualization of urinary calcifications; and 5) NIRF in male infertility and semen quality assessment. Near infrared technology in urology is at its early stages. More studies are needed to assess the true potential and limitations of the technology. Initial studies show that this pioneering tool may influence various aspects of urology.

    More than a decade ago, robotic surgery was introduced into urology. Since then, the urological community started to look at surgery from a different angle. The present, the future hopes, and the way we looked at our past experience have all changed. Between 2000 and 2011, the published literature was reviewed using the National Library of Medicine database and the following key words: robotic surgery, robot-assisted, and radical prostatectomy. Special emphasis was given to the impact of the robotic surgery in urology. We analyzed the most representative series (finished learning curve) in each one of the robotic approaches regarding perioperative morbidity and oncological outcomes. This article looks into the impact of robotics in urology, starting from its background applications before urology, the way it was introduced into urology, its first steps, current status, and future expectations. By narrating this journey, we tried to highlight important modifications that helped robotic surgery make its way to its position today. We looked as well into the dramatic changes that robotic surgery introduced to the field of surgical training and its consequence on its learning curve. Basic surgical principles still apply in Robotics: experience counts, and prolonged practice provides knowledge and skills. In this way, the potential advantages delivered by technology will be better exploited, and this will be reflected in better outcomes for patients. Copyright © 2012 AEU. Published by Elsevier Espana.

    Clinical care parameters are frequently assessed by national ranking systems. However, these rankings do little to comment on institutions' academic contributions. The Publication Ranking Score (PRS) was developed to allow for objective comparisons of scientific thought-leadership at various pediatric urology institutions. Faculty lists were compiled for each of the US News & World Report (USNWR) top-50 pediatric urology hospitals. A list of all faculty publications (2006-2011) was then compiled, after adjusting for journal impact factor, and summed to derive a Publication Ranking Score (PRS). PRS rankings were then compared to the USNWR pediatric urology top-50 hospital list. A total of 1811 publications were indexed. PRS rankings resulted in a mean change in rank of 12 positions, compared to USNWR ranks. Of the top-10 USNWR hospitals, only 4 were ranked in the top-10 by the PRS. There was little correlation between the USNWR and PRS ranks for either top-10 (r = 0.42, p = 0.23) or top-50 (r = 0.48, p = 0.0004) hospitals. PRS institutional ranking differs significantly from the USNWR top-50 hospital list in pediatric urology. While not a replacement, we believe the PRS to be a useful adjunct to the USNWR rankings of pediatric urology hospitals. Copyright © 2013 Journal of Pediatric Urology Company.

    2015-09-01

    The use of Internet panels to collect survey data is increasing because it is cost-effective, enables access to large and diverse samples quickly, takes less time than traditional methods to obtain data for analysis, and the standardization of the data collection process makes studies easy to replicate. A variety of probability-based panels have been created, including Telepanel/CentERpanel, Knowledge Networks (now GFK KnowledgePanel), the American Life Panel, the Longitudinal Internet Studies for the Social Sciences panel, and the Understanding America Study panel. Despite the advantage of having a known denominator (sampling frame), the probability-based Internet panels often have low recruitment participation rates, and some have argued that there is little practical difference between opting out of a probability sample and opting into a nonprobability (convenience) Internet panel. This article provides an overview of both probability-based and convenience panels, discussing potential benefits and cautions for each method, and summarizing the approaches used to weight panel respondents in order to better represent the underlying population. Challenges of using Internet panel data are discussed, including false answers, careless responses, giving the same answer repeatedly, getting multiple surveys from the same respondent, and panelists being members of multiple panels. More is to be learned about Internet panels generally and about Web-based data collection, as well as how to evaluate data collected using mobile devices and social-media platforms.

    Older adults are able to learn and apply new knowledge, such as management of a urological condition, but their learning style differs from that of younger clients. An understanding of the older adult's learning style, and knowledge of specific teaching strategies will benefit the urologic nurse in the ongoing effort to be a more effective patient educator.

  11. JWST Lifting System

    NASA Technical Reports Server (NTRS)

    2012-01-01

    A document describes designing, building, testing, and certifying a customized crane (Lifting Device LD) with a strong back (cradle) to facilitate the installation of long wall panels and short door panels for the GHe phase of the James Webb Space Telescope (JWST). The LD controls are variable-frequency drive controls designed to be adjustable for very slow and very-short-distance movements throughout the installation. The LD has a lift beam with an electric actuator attached at the end. The actuator attaches to a rectangular strong back (cradle) for lifting the long wall panels and short door panels from a lower angle into the vertical position inside the chamber, and then rotating around the chamber for installation onto the existing ceiling and floor. The LD rotates 360 (in very small increments) in both clockwise and counterclockwise directions. Eight lifting pads are on the top ring with 2-in. (.5-cm) eye holes spaced evenly around the ring to allow for the device to be suspended by three crane hoists from the top of the chamber. The LD is operated by remote controls that allow for a single, slow mode for booming the load in and out, with slow and very slow modes for rotating the load.

    Urinary tract infection (UTI) often causes bacteremia, resulting in shock. The purpose of this study is to investigate urological bacteremia and bacteremia shock cases and seek for the clinical factors associated with urological bacteremic shock. Seventy consecutive cases with bacteremia caused by UTI from the Department of Urology, Kobe University Hospital were studied. These cases were diagnosed from 2000 to 2010 and had full data available for analysis. We investigated the potential clinical factors associated with bacteremic shock (systolic blood pressure ≤ 90 mmHg with UTI), including: (1) the number of basal general diseases (such as diabetes, malignancy, immune diseases, heart diseases, liver diseases, and kidney diseases), (2) causative bacteria, (3) antibiotics and therapeutic intervention, (4) gram-negative bacteria, (5) resistance to imipenem (which is often used in this infection), and (6) serum white blood cell counts and C-reactive protein (CRP) at the time of diagnosis of bacteremic UTI. A total of 81 causative bacteria were isolated: 42 cases were gram-negative and 39 were gram-positive bacteria. In detail, Escherichia coli was the most common, followed by Methicillin-resistant Staphylococcus aureus. The comparison data revealed that urological bacteremic shock cases had significantly increased CRP (p < 0.001). Our univariate analyses showed indwelling urinary tract catheters (p = 0.02) as a significant clinical factor associated with urological bacteremic shock and multivariate analyses showed that the presence of indwelling urinary tract catheters before UTI was a significant clinical factor associated with urological bacteremic shock (p = 0.04). Indwelling urinary catheters before UTI and high CRP were clinical factors associated with urological bacteremic shock. This result should be considered during decision-making for UTI treatments in high risk cases or urological bacteremia cases.

    Residents seek postresidency fellowship training to increase competency with novel surgical techniques and augment their fund of knowledge. Research productivity is a vital component of advancement in academic urology. Our objectives were to use the h-index (an objective and readily available bibliometric that has been repeatedly shown to correlate with scholarly impact, funding procurement, and academic promotion in urology as well as other specialties) to determine whether any relationship exists between fellowship training and scholarly impact among academic urologists. Additional examination was performed to determine whether any differences in scholarly influence are present among practitioners in the major urologic subspecialties. Overall, 851 faculty members from 101 academic urology departments were organized by academic rank and fellowship completed. Research productivity was calculated using the h-index, calculated from the Scopus database. There was no statistical difference in h-index found between fellowship-trained and nonfellowship-trained academic urologists. The highest h-indices were seen among urologic oncologists (18.1 ± 0.95) and nonfellowship-trained urologists (14.62 ± 0.80). Nearly 70% of department chairs included in this analysis were urologic oncologists or general urologists. No difference in h-index existed between fellowship-trained and nonfellowship-trained urologists, although practitioners in the subspecialty cohorts with the highest research productivity (nonfellowship-trained and urologic oncologists) comprised 70% of department chairpersons. This relationship suggests that a strong research profile is highly valued during selection for academic promotion. Differences existed on further comparison by subspecialty. Fellowship training may represent another potential opportunity to introduce structured research experiences for trainees. © 2013 Published by Association of Program Directors in Surgery on behalf of Association of Program Directors in Surgery.

    Over the past few decades, simulation-based training has rapidly been adopted by many centres for effective technical and non-technical skills training, as a supplementary method to traditional operating room experience. The aim of this study is to assess the current practice in training and seek opinion regarding the future role of simulation in urological training. A cross sectional survey was designed and distributed amongst expert and trainee urological surgeons. The survey consisted of twenty-two questions that were split into three sections; Introduction (6), Technical Skills training in urology (10) and Non-technical skills training in urology (6). A total of 91 residents and 172 specialists completed the survey. In both groups, there was an agreed consensus that laparoscopic training and exposure was insufficient as only 21% of trainees and 23% of specialists believed that they had sufficient training in this area. Furthermore, both groups lacked simulation-based training in common urological procedures including nephrectomy (62%), cystoscopy (69-74%), ureteroscopy (47-59%), transurethral resection of the prostate (56-65%) and percutaneous renal surgery (76-73%). 90% of trainees and 70% of specialists believed (agreed and strongly agreed) that there is a role for non-technical skills simulation in urological training. Simulation training has been under-used thus far and trainees face an uphill challenge to enhance their skills and technical abilities in the operating room. Simulation is recommended by both trainees and specialists and may represent one of the solutions to the challenges of safe and effective urology procedural training.

    2013-01-01

    With the increased development of distributed sites for medical education across Canada, it is imperative we ensure that the quality of education is comparable between the different campuses. Our objective was to assess medical student experience and comfort with common urologic clinical encounters and to determine whether any differences exist between the distributed education sites at the University of British Columbia (UBC). Questionnaires assessing urologic education were delivered simultaneously to all final-year UBC medical students attending campuses in Vancouver, Victoria and Prince George. Results were analyzed using descriptive statistics. Overall, 55.8% of students felt their exposure to urology was adequate in the medical curriculum; learners in the Northern Program (Prince George) ranked their clinical and didactic experiences significantly higher. Areas requiring improvement include teaching of the male genitourinary exam, digital rectal exam and sexual history, in which learners rated teaching "good/outstanding" in only 18.2%, 47.7% and 43.2% of cases, respectively. Overall, students were most comfortable with the following clinical encounters: urinary tract infection, nephrolithiasis, benign prostatic hyperplasia, hematuria, incontinence and prostate cancer. Few differences in student experience or comfort were noted related to campus site, gender or urology clerkship exposure. A significant minority of learners perceived that they had inadequate exposure to urology in the undergraduate curriculum. Experience in urology was comparable across the distributed sites and was congruent with teaching objectives. Students were comfortable with the clinical scenarios deemed most important in the literature. Learners in the Northern Program were significantly more satisfied with their urologic teaching, which potentially highlights the advantages of learning in a smaller academic setting.

    Make known the important urological work of Sanchez Covisa, third chief of the Urology Service of the Hospital Provincial de Madrid, who beginning in 1928 was able to transform and convert it into possibly the more outstanding one of its time in Spain, comparable to the best hospitals in foreign countries. We have analyzed the contents of the publication Urología Clínica, that collect the changes introduced and the work carried out in said service between 1928 and 1936, reflected in a careful yearly statistics on the care, operations and mortality in addition to the articles published by the members of the Service together with a short bibliographic review of each one. In 1914, he became chief of the Service, and after 14 years, was able to overcome all the obstacles and to extend and modernize the surgery rooms, hospitalization wards and examination resources. In 1931, once the changes were made, he began important clinical and scientific activity, and constituted one of the principal urological schools of the first half of the XXth century in our country. The prestige reached by the Urology Unit of the Hospital Provincial of Madrid attracted patients from all over Spain, many of them treated or operated on in their place of origin. This explains why the condition was complicated with some acceptable results. The quality and honesty of the Urology unit justify its qualification. The works in general are mere reviews and those regarding surgery of the uretero-intestinal shunt stand out. Copyright © 2011 AEU. Published by Elsevier Espana. All rights reserved.

  17. A new era of Asian urology: a SWOT analysis.

    2016-11-01

    Economic prosperity and increasing connectivity have made Asia an emerging centre of growth in health care, including in the field of urology. Large and varied patient populations, the availability of a trained workforce, the use of English as a common communication language, and overall low costs have contributed to this change. Rapid growth of regional urological associations and journals has fuelled the aspirations and abilities of Asian urologists to not only keep abreast of but often lead the change in urological disease management. Asian urology has immense potential to expand in areas in which it currently lags behind, the most important being research. The increasing ability to travel aids in developing networks for collaboration. However, Asian urologists will need to look at sustainable models of engagement and temper the need for short-term results if these opportunities are to reach their maximal potential.

    Alexander von Lichtenberg (1880-1949) was one of the famous members of the German Urological Society (DGU) in pre-war Germany. He introduced excretion urography and a special TURP Instrument. In 1928 he was president of the 8th meeting held in the German capital Berlin. His Handbook of Urology, released by Ferdinand Springer publishing house, was a trendsetter in establishing urology as a specialty in Germany and bringing together the whole wisdom of all aspects of urology. He was the founder of the famous Maximilian Nitze Award of the DGU. As a Jew he-like many others-was forced to leave Nazi Germany after 1933. Even in Hungary, his native country, he again had to resist anti-Semitic hostility. Later on he lived in Mexico. Alexander von Lichtenberg has to be remembered with special focus on the exodus of German Jewish scientists during the Nazi time.

    Members of the International Society of Urological Pathology (ISUP) participated in a half-day consensus conference to discuss guidelines and recommendations regarding best practice approaches to use of immunohistochemistry (IHC) in differential diagnostic situations in urologic pathology, including bladder, prostate, testis and, kidney lesions. Four working groups, selected by the ISUP leadership, identified several high-interest topics based on common or relevant challenging diagnostic situations and proposed best practice recommendations, which were discussed by the membership. The overall summary of the discussions and the consensus opinion forms the basis of a series of articles, one for each organ site. This Special Article summarizes the overall recommendations made by the four working groups. It is anticipated that this ISUP effort will be valuable to the entire practicing community in the appropriate use of IHC in diagnostic urologic pathology.

    Sacral nerve stimulation (SNS) is FDA approved as second-line therapy for both urinary and bowel control. However, there is limited evidence regarding long term safety. We determined adverse events associated with SNS among Medicare beneficiaries. We used the 5% national random sample of Medicare claims for 2001-2011 to identify patients. Patients who underwent SNS implantation were identified with Current Procedure Terminology (CPT-4) codes. We determined safety of SNS using analysis of complication occurrences on day of surgery and during 5 years following initial procedure. SAS v9.3 statistical package was used. One thousand four hundred seventy-four patients underwent treatment with SNS in the 5% national sample of Medicare patients within the time period. Representative of real-world patients undergoing SNS surgery, comorbidities included hypertension (69.3%), diabetes (29.4%), chronic pulmonary disease (25.5%), hypothyroidism (25.2%), and depression (22.7%). Few complications occurred on day of surgery. At 90 days, 3.2% of patients had bowel complications, 2.0% urological, 9.4% infectious, and 1.5% stroke. Overall, bowel, neurological health event occurrences were consistent with prior year rates, while infectious events decreased. Of 206 patients who were followed for at least 5 years, 17.3% had devices removed and 11.3% replaced, with 26.1% having at least one of those, leaving 73.9% with original devices. Urological, infectious, and bowel complication occurrences were low after SNS among Medicare beneficiaries with multiple comorbidities. There were infrequent serious complications like hemorrhage and stroke postoperatively. Although SNS appears safe in this high-risk population, a comprehensive registry will ensure continuous safety. © 2014 Wiley Periodicals, Inc.

A review of national guidelines and articles published on the subject in the Medline database, selected by keywords, depending on the scientific relevance was performed. While the epidemiology clearly shows the non-reduction of the anti-infectious treatments use in France, the resistance increases to highlight foo-resistant germs. Urology is not an exception to this observation, and different means are set to improve the prescription made by urologists. The epidemiological observation confirms the urgent need to improve the prescription of anti-infectious treatments particularly in urology. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    To examine the rationale and applications of amniotic tissue augmentation in urological surgery. Published literature in English-language was reviewed for basic science and clinical use of amniotic or amnion-chorionic tissue in genitourinary tissues. Basic science and animal studies support the likely benefit of clinical applications of amnion-derived tissues in a variety of urologic interventions. The broad number of properties found in amniotic membrane, coupled with its immunologically privileged status presents a number of future applications in the urological surgical realm. These applications are in their clinical infancy and suggest that further studies are warranted to investigate the use of these products in a systematic fashion.

    To present the epidemiological, clinical and therapeutic features of the urological emergencies in Senegal, West Africa. The authors conducted a 20 months retrospective study that analyzed the epidemiological, clinical and therapeutic features of all urological emergencies admitted to the urology department of the university teaching hospital Aristide-Le-Dantec (Dakar). There were 1237 urological emergencies. The mean age of the patients was 58.8 years (range one month-94 years). The sex ratio (M/F) was 20.32. These patients had an age equal to or higher than 60 years in 50.7% of the cases. The most frequent illness was urinary retention (53%) and genitor-urinary system infectious, which represented as a whole 16.4% of the cases. The gangrenes of male external genitalia (Fournier's gangrene) accounted for 4.1% of the cases and the priapism 1.3%. In emergency, 331 surgical operations were performed. The most performed procedures were the installation of a suprapubic catheter (59.8%) and debridement of a gangrene of male external genitalia (15.4%). The most frequent urological emergency in our country was the acute urinary retention. Some serious illness like gangrene of male external genitalia (Fournier's gangrene) and priapism are not rare there.

  8. Urologic Diseases in Korean Military Population: a 6-year Epidemiological Review of Medical Records

    PubMed Central

    2017-01-01

    We sought to describe the incidence rate of the urologic disease in the Korean military by reviewing diagnoses made in active duty soldiers from 2008 to 2013. A total of 72,248 first visits were generated in the Defense Medical Statistics Information System (DMSIS) with its gradually increasing trend over 6 years. A sharp increase of first visit was observed after implementation of the regular health check-up for all conscripted soldiers since 2013. Urolithiasis, prostatitis, epididymoorchitis, urethritis, and varicocele were prevalent. Prostatitis was the highest diagnosis made in the outpatient service, while varicocele was ranked the highest in the inpatient service. The incidence rates of urologic disease varied from 12.3 to 34.2 cases per 1,000 person-years. The urologic disease in conscripted men showed different distribution when we separated the population into conscripted and professional soldiers. Epididymoorchitis was the highest disease followed by urolithiasis, dysuresia, and balanoposthitis in 2013. This study underscores that the urologic disease has spent significant amount of health care resources in the Korean military. This calls for further study to find any significant difference and contributing factors of the urologic disease in the military and the civilian population. PMID:27914143

  9. Simulation of an active cooling system for photovoltaic modules

    Abdelhakim, Lotfi

    2016-06-01

    Photovoltaic cells are devices that convert solar radiation directly into electricity. However, solar radiation increases the photovoltaic cells temperature [1] [2]. The temperature has an influence on the degradation of the cell efficiency and the lifetime of a PV cell. This work reports on a water cooling technique for photovoltaic panel, whereby the cooling system was placed at the front surface of the cells to dissipate excess heat away and to block unwanted radiation. By using water as a cooling medium for the photovoltaic solar cells, the overheating of closed panel is greatly reduced without prejudicing luminosity. The water also acts as a filter to remove a portion of solar spectrum in the infrared band but allows transmission of the visible spectrum most useful for the PV operation. To improve the cooling system efficiency and electrical efficiency, uniform flow rate among the cooling system is required to ensure uniform distribution of the operating temperature of the PV cells. The aims of this study are to develop a 3D thermal model to simulate the cooling and heat transfer in Photovoltaic panel and to recommend a cooling technique for the PV panel. The velocity, pressure and temperature distribution of the three-dimensional flow across the cooling block were determined using the commercial package, Fluent. The second objective of this work is to study the influence of the geometrical dimensions of the panel, water mass flow rate and water inlet temperature on the flow distribution and the solar panel temperature. The results obtained by the model are compared with experimental results from testing the prototype of the cooling device.

    We sought to develop a core set of clinical indicators to enable international benchmarking of localized prostate cancer management using data available in the TrueNTH (True North) Global Registry. An international expert panel completed an online survey and participated in a face to face meeting. Participants included 3 urologists, 3 radiation oncologists, 2 psychologists, 1 medical oncologist, 1 nurse and 1 epidemiologist with prostate cancer expertise from a total of 7 countries. Current guidelines on prostate cancer treatment and potential quality indicators were identified from a literature review. These potential indicators were refined and developed through a modified Delphi process during which each panelist independently and repeatedly rated each indicator based on importance (satisfying the indicator demonstrated a provision of high quality care) and feasibility (the likelihood that data used to construct the indicator could be collected at a population level). The main outcome measure was items with panel agreement indicted by a disagreement index less 1, median importance 8.5 or greater and median feasibility 9 or greater. The expert panel endorsed 33 indicators. Seven of these 33 prostate cancer quality indicators assessed care relating to diagnosis, 7 assessed primary treatment, 1 assessed salvage treatment and 18 assessed health outcomes. We developed a set of quality indicators to measure prostate cancer care using numerous international evidence-based clinical guidelines. These indicators will be pilot tested in the TrueNTH Global Registry. Reports comparing indicator performance will subsequently be distributed to groups at participating sites with the purpose of improving the consistency and quality of prostate cancer management on a global basis.

Materials and Methods: After establishing hydronephrosis, ten pigs had three calyxes of each kidney punctured by the same urology resident, with and without the new device (“Punctiometer”). Time for procedure completion, number of attempts to reach the calyx, puncture precision and puncture complications were recorded in both groups and compared. Results: Puncture success on the first attempt was achieved in 25 punctures (83%) with the Punctiometer and in 13 punctures (43%) without the Punctiometer (p=0.011). The mean time required to perform three punctures in each kidney was 14.5 minutes with the Punctiometer and 22.4 minutes without the Punctiometer (p=0.025). The only complications noted were renal hematomas. In the Punctiometer group, all kidneys had small hematomas. In the no Punctiometer group 80% had small hematomas, 10% had a medium hematoma and 10% had a big hematoma. There was no difference in complications between both groups. Conclusions: The Punctiometer is an effective device to increase the likelihood of an accurate renal calyx puncture during PCNL, with a shorter time required to perform the procedure. PMID:26689521

    Analyzing microRNAs (miRNAs) within urine extracellular vesicles (EVs) is important for realizing miRNA-based, simple, and noninvasive early disease diagnoses and timely medical checkups. However, the inherent difficulty in collecting dilute concentrations of EVs (<0.01 volume %) from urine has hindered the development of these diagnoses and medical checkups. We propose a device composed of nanowires anchored into a microfluidic substrate. This device enables EV collections at high efficiency and in situ extractions of various miRNAs of different sequences (around 1000 types) that significantly exceed the number of species being extracted by the conventional ultracentrifugation method. The mechanical stability of nanowires anchored into substrates during buffer flow and the electrostatic collection of EVs onto the nanowires are the two key mechanisms that ensure the success of the proposed device. In addition, we use our methodology to identify urinary miRNAs that could potentially serve as biomarkers for cancer not only for urologic malignancies (bladder and prostate) but also for nonurologic ones (lung, pancreas, and liver). The present device concept will provide a foundation for work toward the long-term goal of urine-based early diagnoses and medical checkups for cancer. PMID:29291244

    Background Appropriate use of inhaled therapies for asthma and chronic obstructive pulmonary disease (COPD) is critical to ensuring good patient outcomes, efficient use of healthcare resources and limiting the effects of high-morbidity. The appropriate choice of inhaler and active therapy, incorporating patient preferences, can help improve treatment adherence and long-term outcomes. Despite this, many current inhalers are non-intuitive to use, and require extensive training. Methods In this review, an expert panel considers the evidence for the use of inhaler devices in management of COPD and asthma. The panel also evaluates the value of innovation in inhaler technologies, which optimise the use of existing molecules from a clinical, economic and societal perspective. Conclusions The panel conclusion is that there remains a substantial unmet need in inhaler technology and that innovation in inhaler devices can provide real-world health benefits to patients. Furthermore, we recommend that these innovations should be supported by healthcare systems through appropriate pricing and reimbursement mechanisms. PMID:27123170

    Hypertension is the leading cause of mortality throughout Asia. Home blood pressure monitoring has the potential to improve hypertension control and is a useful adjunct to conventional office blood pressure measurements due to its diagnostic accuracy and prognostic value in predicting cardiovascular outcomes. At present, there are no region-specific guidelines addressing the use of home blood pressure monitoring in Asia. Therefore, an expert panel was convened to address the use of home blood pressure monitoring and develop key recommendations to help guide clinical practice throughout the Asia region. The resulting recommendations support the use of home blood pressure monitoring with a validated device as an accurate adjunct for diagnosing hypertension and predicting cardiovascular outcome. Diagnosis and treatment of hypertension should still be guided by conventional office/clinic blood pressure measurements. The expert panel encourages the incorporation of home blood pressure monitoring into local clinical guidelines and offers practical recommendations to ensure continuity of care where a validated home blood pressure device is not available.

    To quantify the frequency of genitourinary (GU) physical examinations obtained by the emergency department or primary hospital team before obtaining a urologic consultation and evaluate the role of the different demographic and clinical factors. For 6 weeks, from July to August 2010, 420 consecutive patients evaluated by the urology consultation service had their medical charts reviewed retrospectively, with the frequency of GU physical examination performed by the emergency department or primary hospital team recorded. Of 357 patients requiring a urologic consultation, 88 of 324 (27%) had a GU physical examination performed by the emergency department and 98 of 319 (31%) had a GU physical examination performed by the primary hospital team before the urologic consultation. The emergency department was 6 times more likely to perform a GU physical examination on a male patient than a female patient, and the primary team was twice as likely to perform a GU physical examination on a male patient than a female patient. The likelihood of examination by either team decreased as patients became older. Race was not significantly associated with the likelihood of examination. The results of our study indicate that examinations are performed less than one-third of the time before obtaining a urologic consultation, with the frequency related to age and sex. The low rate of preconsultation examination creates concern for quality of care, the correctness of billing, and unnecessary urologic consultations. Copyright © 2012 Elsevier Inc.

    The presence of women in urology has gradually increased in the last 35 years with an accelerated rate in the last decade. We evaluated manuscript authorship trends by gender. Manuscript authorship is a metric that has been used as a marker of academic productivity. We hypothesized that the number of first and last author publications by women has increased proportionately to the number of women in the field during the last 35 years. We performed a bibliometric study to examine authorship gender in The Journal of Urology® and Urology®. We reviewed all original articles published from American institutions in 1974, 1979, 1984, 1989, 1994, 1999, 2004 and 2009. Of the 8,313 articles reviewed 5,461 were from American institutions, including 97.5% for which we determined author gender. There were 767 articles with female authors, including 440 first and 327 last authors. First and last female authorship increased from 2.7% of all authors in 1979 to 26.5% in 2009 (test for trend p <0.001). This authorship rate surpasses the rate of growth of women in urology, which increased from 0.24% in 1975 to 6.2% in 2008. Based on authorship gender analysis women urologists produce manuscripts at a rate that exceeds their number in the field. Findings show that women in urology are productive, active members of the academic community. Copyright © 2012 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

    Studies using routinely collected data (RCD) are common in the urological literature; however, there are important considerations in the creation and review of RCD discoveries. A recent reporting guideline (REporting of studies Conducted using Observational Routinely-collected health Data, RECORD) was developed to improve the reporting of these studies. This narrative review examines important considerations for RCD studies. To assess the current level of reporting in the urological literature, we reviewed all the original research articles published in Journal of Urology and European Urology in 2014, and determined the proportion of the RECORD checklist items that were reported for RCD studies. There were 56 RCD studies identified among the 608 articles. When the RECORD items were considered applicable to the specific study, they were reported in 52.5% of cases. Studies most consistently (>80% of them) reported the names of the data sources, the study time frame, the extent to which the authors could access the database source, the patient selection, and discussed missing data. Few studies (<25%) discussed validation of key coding elements, details on data-linkage, data-cleaning, the impact of changing eligibility over time, or provided the complete list of coding elements used to define key study variables. Reporting factors specifically relevant in RCD studies may serve to increase the quality of these studies in the urological literature. With increased technological integration in healthcare and the proliferation of electronic medical records, RCD will continue to be an important source for urological research.

    To determine the feasibility of obtaining cooperation from urologists in carrying out large-scale studies on the efficacy of acupuncture for the treatment of urological conditions, based on urologists' general views and knowledge of acupuncture. A questionnaire was distributed to 145 urologists within three training deaneries within England. A response rate of 70% (n=102) was achieved. The majority of urologists rated their knowledge of acupuncture as low (46%, n=46) and their general attitude towards acupuncture was neutral (54%, n=55). The majority of responding urologists (95%) thought that acupuncture may be of value in urological conditions, and acupuncture was suggested to patients by 30 urologists (29%). The urologists most likely to suggest acupuncture to their patients were typically over 40 years of age, more experienced, not in a training post, and since starting their urological career had changed their attitude towards acupuncture. In a multivariate analysis, a change of view regarding the efficacy of acupuncture was found to be the only variable significantly associated with a recommendation of acupuncture to patients. Although overall knowledge about acupuncture was poor, most responding urologists thought acupuncture may be useful for urological conditions. Those who had changed their views were most likely to suggest acupuncture to their patients. Acupuncture for urological conditions warrants further investigation and, as this study has shown high interest within the urological community large clinical trials involving multicentres may be feasible.

    Through the widespread availability of location-identifying devices, geolocalisation could potentially be used to place athletes during out-of-competition testing. In light of this debate, the WADA Ethics Panel formulated the following questions: (1) should WADA and/or other sponsors consider funding such geolocalisation research projects?, (2) if successful, could they be proposed to athletes as a complementary device to Anti-Doping Administration and Management System to help geolocalisation and reduce the risk of missed tests? and (3) should such devices be offered on a voluntary basis, or is it conceivable that they would be made mandatory for all athletes in registered testing pools? In this position paper, the WADA Ethics Panel concludes that the use of geolocalisation could be useful in a research setting with the goal of understanding associations between genotype, phenotype and environment; however, it recognises that the use of geolocalisation as part of or as replacement of whereabouts rules is replete with ethical concerns. While benefits remain largely hypothetical and minimal, the potential invasion of privacy and the data security threats are real. Considering the impact on privacy, data security issues, the societal ramifications of offering such services and various pragmatic considerations, the WADA Ethics Panel concludes that at this time, the use of geolocalisation should neither be mandated as a tool for disclosing whereabouts nor implemented on a voluntary basis. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.
