RESUMEN
Background: Duplex kidneys may be associated with additional pathologies with an indication for surgery. Various surgical approaches have been described. However, little is known about long-term outcomes and quality of life (QoL) for these patients. Objective: To present long-term outcomes and QoL data up to 30 yr after surgical treatment of duplex kidneys and associated pathologies. Design setting and participants: We collected clinical and operative data for all patients who underwent surgery for complicated duplex kidney at our institution from 1990 to 2018. All patients were invited for a follow-up examination or telephone interview. Outcome measurements and statistical analysis: We evaluated renal function, clinical outcomes, residual dilation of the upper urinary tract, and health-related QoL. Results and limitations: Of the 176 patients included, 173 were available for follow-up (mean 140.5 mo). Surgical treatment involved an upper-tract, lower-tract, or combined approach in 11%, 56%, and 33% of cases, respectively. Rates of perioperative complications (8%) and secondary surgery (10%) were low. Overall, 95% of our patients achieved full restitution. Renal function was preserved in all cases, with recurrent urinary tract infections reported by just 2% and urinary incontinence by 1%. Good health-related QoL was reported by 98% of patients. Those without full restitution included six patients who underwent total nephrectomy and two boys who underwent multiple surgeries and urinary diversion. Our results are limited by their retrospective nature, including partly incomplete data sets. Conclusions: Management of duplex kidneys and associated pathologies is complex and highly individual. By planning a personal approach for each patient it is possible to achieve full bodily integrity and good QoL for most of these patients. Patient summary: Almost all patients undergoing surgery for duplex kidneys and associated pathologies will lead a life without body impairment and good quality of life.This trial is registered in the German Clinical Trials Register as DRKS00022542.
RESUMEN
BACKGROUND: Specialist titles are mutually recognized in the DACH (Germany [D], Austria [A], and Switzerland [CH]) region. During continuing education, however, there are significant differences in structure, organization and content. OBJECTIVES: Organization, formalities and responsibilities, as well as admission requirements for the final examinations, in particular the examination formats in the DACH countries will be examined. In addition, these will be critically examined from the perspective of modern medical education. MATERIALS AND METHODS: Documents publicly available on the Internet from the responsible authorities for continuing medical education in the DACH region were analyzed. In addition, a narrative review of the literature in medical databases on the topic of continuing medical education in urology was performed. RESULTS: The minimum duration of residency is 5 (D) to 6 years (A, CH). Basic (surgical) training is mandatory in Austria and Switzerland. In Switzerland, the training site must be changed at least once. Part-time training is possible in all countries. Research and participation in annual congresses are mandatory only in Switzerland. Formative examinations are only required in Switzerland. In all countries, at least one summative examination is required to obtain the specialist title. In Austria and Switzerland, the written part of the European Board of Urology (EBU) examination must be passed. CONCLUSION: From a medical education perspective, Switzerland currently offers and demands the most modern elements in specialist training. The certified structured continuing education modelled on the "Deutschen Gesellschaft für Urologie" (DGU; "Weiterbildungscurriculum Urologie", WECU) in Germany integrates modern approaches in Germany. With timely implementation of, for example, entrustable professional activities (EPAs), urology in German-speaking countries could be pioneering nations and disciplines internationally.

PURPOSE: We aimed to assess critical temperature areas in the kidney parenchyma using magnetic resonance thermometry (MRT) in an ex vivo Holmium:YAG laser lithotripsy model. METHODS: Thermal effects of Ho:YAG laser irradiation of 14 W and 30 W were investigated in the calyx and renal pelvis of an ex vivo kidney with different laser application times (tL) followed by a delay time (tD) of tL/tD = 5/5 s, 5/10 s, 10/5 s, 10/10 s, and 20/0 s, with irrigation rates of 10, 30, 50, 70, and 100 ml/min. Using MRT, the size of the area was determined in which the thermal dose as measured by the Cumulative Equivalent Minutes (CEM43) method exceeded a value of 120 min. RESULTS: In the calyx, CEM43 never exceeded 120 min for flow rates ≥ 70 ml/min at 14 W, and longer tL (10 s vs. 5 s) lead to exponentially lower thermal affection of tissue (3.6 vs. 21.9 mm2). Similarly at 30 W and ≥ 70 ml/min CEM43 was below 120 min. Interestingly, at irrigation rates of 10 ml/min, tL = 10 s and tD = 10 s CEM43 were observed > 120 min in an area of 84.4 mm2 and 49.1 mm2 at tD = 5 s. Here, tL = 5 s revealed relevant thermal affection of 29.1 mm2 at 10 ml/min. CONCLUSION: We demonstrate that critical temperature dose areas in the kidney parenchyma were associated with high laser power and application times, a low irrigation rate, and anatomical volume of the targeted calyx.

INTRODUCTION: Guideline recommendations are meant to help minimize morbidity and to improve the care of nonmuscle invasive bladder cancer (NMIBC) patients but studies have suggested an underuse of guideline-recommended care. The aim of this study was to evaluate the level of adherence of German and Austrian urologists to German guideline recommendations. METHODS: A survey of 27 items evaluating diagnostic and therapeutic recommendations (15 cases of strong consensus and 6 cases of consensus) for NMIBC was administered among 14 urologic training courses. Survey construction and realization followed the checklist for reporting results of internet e-surveys and was approved by an internal review board. RESULTS: Between January 2018 and June 2019, a total of 307 urologists responded to the questionnaire, with a mean response rate of 71%. The data showed a weak role of urine cytology (54%) for initial diagnostics although it is strongly recommended by the guideline. The most frequently used supporting diagnostic tool during transurethral resection of the bladder was hexaminolevulinate (95%). Contrary to the guideline recommendation, 38% of the participants performed a second resection in the case of pTa low-grade NMIBC. Correct monitoring of Bacille Calmette-Guérin (BCG) response with cystoscopy and cytology was performed by only 34% of the urologists. CONCLUSIONS: We found a discrepancy between certain guideline recommendations and daily routine practice concerning the use of urine cytology for initial diagnostics, instillation therapy with a low monitoring rate of BCG response, and follow-up care with unnecessary second resection after pTa low-grade NMIBC in particular. Our survey showed a moderate overall adherence rate of 73%. These results demonstrate the need for sharpening awareness of German guideline recommendations by promoting more intense education of urologists to optimize NMIBC care thus decreasing morbidity and mortality rates.

BACKGROUND: Antithrombotic therapy is complex and requires informed decisions and high therapy adherence. Several mobile phone apps exist to either support physicians in the management of antithrombotic therapies or to educate and support patients. For the majority of these apps, both their medical evidence and their development background are unknown. OBJECTIVE: This review aims to investigate the available literature describing high-quality apps for managing antithrombotic therapy based on professional scientific information. METHODS: Keywords and Medical Subject Heading terms were used to search MEDLINE via PubMed and Ovid between December 2019 and January 2022. Inclusion criteria were the availability of full text and publications in the English language. Apps that solely focused on atrial fibrillation were excluded. Qualitative findings were thematically synthesized and reported narratively. RESULTS: Out of 149 identified records, 32 were classified as eligible. We identified four groups: (1) apps for patients supporting self-management of vitamin K antagonists, (2) apps for patients increasing therapy adherence, (3) educational apps for patients, and (4) apps for physicians in supporting guideline adherence. CONCLUSIONS: Throughout the evaluated data, patients from all age groups receiving antithrombotic drugs expressed the desire for a digital tool that could support their therapy management. In addition, physicians using mobile guideline-based apps may have contributed to decreased adverse event rates among their patients. In general, digital apps encompassing both user-friendly designs and scientific backgrounds may enhance the safety of antithrombotic therapies. However, our evaluation did not identify any apps that addressed all antithrombotic drugs in combination with perioperative stratification strategies. Currently, strict regulations for smartphone apps seem to negatively affect the development of new apps. Therefore, new legal policies for medical digital apps are urgently needed.
RESUMEN
Data comparing treatments for urolithiasis are often outdated, with inconsistent results or poor methodological and reporting quality. We report a pilot study in preparation for a larger multicentre randomised controlled trial (RCT) comparing shockwave therapy and ureteroscopy in patients with a single urinary stone of ≤20 mm in the upper urinary tract. Primary objectives included screening completeness, patients' willingness to participate, their remaining in the study, the suitability of the eligibility criteria, and the acceptability of the outcome measures. Screened individuals not invited to participate were those with no indication for active treatment among referred patients (n = 166), those who staff failed to screen (n = 99), and patients not meeting the inclusion criterion of a single stone (n = 422). Of the 176 patients invited, 116 refused to participate. Ultimately, we were able to recruit 60 patients within 34 mo. All patients underwent their allocated treatments. This pilot trial provides an in-depth analysis of the feasibility of an RCT on surgical treatments for upper urinary tract urolithiasis in a highly regulated health care system. The study procedures and outcome measures proved acceptable and feasible. On the basis of these data, we propose a pragmatic, multicentre RCT to deliver updated, high-level evidence on the efficacy of currently available treatments for urolithiasis. PATIENT SUMMARY: We performed a small pilot trial comparing current treatments in urolithiasis. We were able to prove the feasibility of a larger multi-institutional trial with regard to the time needed to recruit an adequate number of patients and the acceptability of the treatments and outcome measures.

INTRODUCTION: For decades, automatic speech recognition (ASR) has been the subject of research and its range of applications broadened. Presently, ASR among physicians is mainly used to convert speech into text but not to implement instructions in the operating room (OR). This study aimed to evaluate physicians of different surgical professions on their personal experience and posture towards ASR. METHODS: A 16-item survey was distributed electronically to hospitals and outpatient clinics in southern Germany addressing physicians on the potential applications of ASR in the OR. RESULTS: The survey was responded by 185 of 2693 physicians (response rate: 6.9%) with a mean age of 41.8 ± 9.8 years. ASR is desirable in the OR regardless of the field of speciality (93.7%). While only 2.7% have used ASR, 87.9% evaluate its future potential as high. 91.0% of those working in a university hospital would consider testing ASR, while 67.5% of those in non-university hospitals and practices (p = 0.001). 90.1% of responders of strictly surgical specialities see potential in ASR while 73.7% in non-surgical specialities evaluate its future potential as high (p = 0.01). 58.3% of those over the age of 60 consider the use of ASR without a headset to be imaginable, while 96.3% among those under the age of 60. There were no statistically significant differences regarding sex and professional position. CONCLUSION: Foreseeably, ASR is anticipated to be integrated into ORs and valued at a high market potential. Our study provides information about physicians' individual preferences from various surgical disciplines regarding ASR.
RESUMEN
A group of 22 medical educators from different European countries, gathered in a meeting in Utrecht in July 2019, discussed the topic of learning analytics (LA) in an open conversation and addressed its definition, its purposes and potential risks for learners and teachers. LA was seen as a significant advance with important potential to improve education, but the group felt that potential drawbacks of using LA may yet be under-exposed in the literature. After transcription and interpretation of the discussion's conclusions, a document was drafted and fed back to the group in two rounds to arrive at a series of 10 caveats educators should be aware of when developing and using LA, including too much standardized learning, with undue consequences of over-efficiency and pressure on learners and teachers, and a decrease of the variety of 'valid' learning resources. Learning analytics may misalign with eventual clinical performance and can run the risk of privacy breaches and inescapability of documented failures. These consequences may not happen, but the authors, on behalf of the full group of educators, felt it worth to signal these caveats from a consumers' perspective.
