Prevalence of urinary tract cancer in the Spanish cohort of the IDENTIFY study.

INTRODUCTION: Malignant tumors of the urinary tract are associated with high morbidity and mortality, and their prevalence can vary worldwide. Recently, the IDENTIFY study has published results on the prevalence of urinary tract cancer at a global level. This study evaluates the prevalence of cancer within the Spanish cohort of the IDENTIFY study to determine whether the published results can be extrapolated to our population. PATIENTS AND METHODS: An analysis of the data from the Spanish cohort of patients in the IDENTIFY study was performed. This is a prospective cohort of patients referred to secondary care with suspected cancer, predominantly due to hematuria. Patients were recruited between December 2017 and December 2018. RESULTS: A total of 706 patients from 9 Spanish centers were analyzed. Of these, 277 (39.2%) were diagnosed with cancer: 259 (36.7%) bladder cancer, 10 (1.4%) upper tract urothelial carcinoma, 9 (1.2%) renal cancer and 5 (0.7%) prostate cancer. Increasing age (OR 1.05 (95% CI 1.03-1.06; P < 0.001)), visible hematuria (VH) OR 2.19 (95% CI 1.13-4.24; P = 0.02)) and smoking (ex-smokers: OR 2.11(95% CI 1.30-3.40; P = 0.002); smokers: OR 2.36 (95% CI 1.40-3.95; P = 0.001)) were associated with higher probability of bladder cancer. CONCLUSION: This study highlights the risk of bladder cancer in patients with VH and smoking habits. Bladder cancer presented the highest prevalence; higher than the prevalence reported in previous series and presented in the IDENTIFY study. Future work should evaluate other associated factors that allow us to create cancer prediction models to improve the detection of cancer in our patients.

Impact of a delayed presentation to the emergency department for acute renal colic on biochemical and clinical outcomes.

INTRODUCTION AND OBJECTIVE: To verify the impact of delay on biochemical and clinical outcomes for patients presenting to the emergency department (ED) with acute renal colic. MATERIALS AND METHODS: Data were retrospectively collected from three institutions of two European countries between 01 January and 30 April 2020. Patients who presented to the ED with unilateral or bilateral renal colic caused by urolithiasis confirmed by imaging tests during the study period were included. A presentation after 24 h since the onset of symptoms was considered a delay. Patients presenting before 24 h from the symptom onset were included in Group A, while the patients presenting after 24 h in Group B. Clinical and biochemical parameters and management were compared. RESULTS: A total of 397 patients who presented to ED with confirmed urolithiasis were analyzed (Group A, n = 199; Group B, n = 198. The median (IQR) delay in presentation was 2 days (1,5-4). At presentation, no statistically significant differences were found amongst the two groups of patients regarding presenting symptoms such as fever and flank pain, and the median serum levels of creatinine, C reactive protein and white blood cells. No differences were found in terms of conservative or operative management. CONCLUSION: Delay in consultation >24 h is not associated with worsening biochemical parameters and clinical outcomes. Most patients with acute loin pain do not necessarily need urgent attendance to the ED and may be managed in the outpatients.

The effect of neoadjuvant chemotherapy among patients undergoing radical cystectomy for variant histology bladder cancer: A systematic review.

OBJECTIVE: To systematically review the evidence about the effect of neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC) with pure urothelial carcinoma (pUC) in radical cystectomy (RC) candidates affected by variant histology (VH) bladder cancer. METHODS: A review of the current literature was conducted through the Medline and National Center for Biotechnology Information (NCBI) PubMed, Scopus databases in May 2020. The updated Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed for this systematic review. Keywords used were 'bladder cancer', 'bladder carcinoma', 'bladder tumour' and 'bladder cancer variants' and 'neoadjuvant chemotherapy'. Only original articles in English published after 2000 and reporting oncological outcomes a series of more than five patients with VH were included. We excluded series in which the oncological outcomes of patients with pUC and VH were undistinguishable. RESULTS: The literature search identified 2231 articles. A total of 51 full-text articles were assessed for eligibility, with 17 eventually considered for systematic review, for a cohort of 450,367 patients, of which 5010 underwent NAC + RC. The median age at initial diagnosis ranged from 61 to 71 years. Most patients received cisplatin-gemcitabine, methotrexate-vinblastine-adriamycin-cisplatin, or carboplatin-based chemotherapy. Only one study reported results of neoadjuvant immunotherapy. The median follow-up ranged from 1 to 120 months. The results showed that squamous cell carcinoma (SCC) is less sensitive to NAC than pUC and that SCC predicts poorer prognosis. NAC was found to be a valid approach in treating small cell carcinoma and may have potential benefit in micropapillary carcinoma. CONCLUSIONS: NAC showed the best oncological outcomes in small cell variants and micropapillary carcinoma, while NAC survival benefit for SCC and adenocarcinoma variants needs further studies. Drawing definite considerations on the efficacy of NAC in VH is complicated due to the heterogeneity of present literature. Present results need to be confirmed in randomised controlled trials.

The role of multiparametric magnetic resonance imaging in the selection and follow-up of patients undergoing active surveillance for prostate cancer. An European Section of Uro-Technology (ESUT) review. / Papel de la resonancia magnética multiparamétrica en la selección y el seguimiento de pacientes en vigilancia activa por cáncer de próstata. Revisión del grupo de Uro-Tecnología (ESUT) de la EAU.

INTRODUCTION: In recent years, active surveillance (AS) has gained popularity as a safe and reasonable option for patients with low-risk, clinically localized prostate cancer. OBJECTIVE: To summarize the latest information regarding the use of mpMRI in the setting of active surveillance (AS) for the management of prostate cancer (PCa). EVIDENCE ACQUISITION: A PubMed-based, English literature search was conducted through February 2020. We selected the most relevant original articles, meta-analyses and systematic reviews that could provide important information. EVIDENCE SYNTHESIS: The great importance of mpMRI of the prostate in the setting of PCa diagnosis is its ability to visualize primarily high-grade cancerous lesions potentially missed on systematic biopsies. In several studies, mpMRI has shown an improved performance over clinically based models for identifying candidates which will benefit the most from AS. Although data on prostate mpMRI during follow-up of men under AS is sparse, it holds the probability to improve significantly AS programs by a more precise selection of optimal candidates, a more accurate identification of disease progression and a reduction in number of biopsies. The goal of reassessment of patients undergoing AS is to find the most effective moment to change attitude to active treatment. CONCLUSION: The value of mpMRI has been recognized due to its high negative predictive value (NPV) for lesion upgrading in low-risk PCa patients. The improvement in imaging detection, and precise diagnosis with mpMRI could reduce misclassifications at initial diagnosis and during follow-up, reducing the number of biopsies.

Prognostic value of urinary cytology for detecting urothelial carcinoma recurrence after radical cystectomy.

INTRODUCTION: Urethral or upper urinary tract (UUT) recurrence of urothelial carcinoma (UC) after radical cystectomy (RC) are rare (4-6%), and their diagnosis usually occurs within the first two years. Although it is known that its early detection offers benefit in terms of survival, currently there are no clear recommendations for the detection of recurrence in the remnant urothelium (RU). Our aim is to determine the diagnostic value of urinary cytology for the detection of recurrences in the RU and to estimate its impact as an early diagnostic method on survival. MATERIAL AND METHODS: Retrospective review of patients who underwent RC for urothelial carcinoma between 2008-2016, with a follow-up of at least 24 months. RESULTS: The study included 142 patients. In a median follow-up of 68.5 months, nine patients (6.3%) presented recurrences in the RU (urethra: four, UUT: four, synchronous: one). The sensitivity and specificity of urinary cytology for the diagnosis of UUT recurrences were 20% and 96%, respectively. No significant differences were found between overall survival and cancer-specific survival among patients according to the urinary cytology results. CONCLUSION: Recurrences in the RU after RC are infrequent; our study has shown that urinary cytology offers a low sensitivity for their diagnoses. For these reasons, we do not consider that urinary cytology provides useful information for surveillance of these patients.

Exploring the Residents' Perspective on Smart learning Modalities and Contents for Virtual Urology Education: Lesson Learned During the COVID-19 Pandemic. / Explorando la perspectiva de los residentes sobre las modalidades y contenidos de aprendizaje inteligente para la educación virtual de urología: lección aprendida durante la pandemia de la COVID-19.

PURPOSE: The COVID-19 outbreak has substantially altered residents' training activities. While several new virtual learning programs have been recently implemented, the perspective of urology trainees regarding their usefulness still needs to be investigated. METHODS: A cross-sectional, 30-item, web-based Survey was conducted through Twitter from April 4th, 2020 to April 18th, 2020, aiming to evaluate the urology residents' perspective on smart learning (SL) modalities (pre-recorded videos, webinars, podcasts, and social media [SoMe]), and contents (frontal lessons, clinical case discussions, updates on Guidelines and on clinical trials, surgical videos, Journal Clubs, and seminars on leadership and non-technical skills). RESULTS: Overall, 501 urology residents from 58 countries completed the survey. Of these, 78.4, 78.2, 56.9 and 51.9% of them considered pre-recorded videos, interactive webinars, podcasts and SoMe highly useful modalities of smart learning, respectively. The contents considered as highly useful by the greatest proportion of residents were updates on guidelines (84.8%) and surgical videos (81.0%). In addition, 58.9 and 56.5% of responders deemed seminars on leadership and on non-technical skills highly useful smart learning contents. The three preferred combinations of smart learning modality and content were: pre-recorded surgical videos, interactive webinars on clinical cases, and pre-recorded videos on guidelines. CONCLUSION: Our study provides the first global «big picture¼ of the smart learning modalities and contents that should be prioritized to optimize virtual Urology education. While this survey was conducted during the COVID-19 outbreak, our findings might have even more impact in the future.

Assessment of trends and clinical presentation in the emergency department of patients with renal colic during the COVID-19 pandemic era. / Evaluación de las tendencias y presentación clínica de pacientes con cólico nefrítico que acuden al servicio de urgencias durante la era pandémica del COVID-19.

INTRODUCTION: We hypothesized that the recent COVID-19 pandemic may lead to a delay in renal colic patients presenting to the Emergency Department due to the fear of getting infected. This delay may lead to a more severe clinical condition at presentation with possible complications for the patients. MATERIAL AND METHODS: Retrospective review of data collected from three institutions from Spain and Italy. Patients who presented to Emergency Department with unilateral or bilateral renal colic caused by imaging confirmed urolithiasis during the 45 days before and after each national lockdown were included. Data collected included patients' demographics, biochemical urine and blood tests, radiological tests, signs, symptoms and the therapeutic management. Analysis was performed between two groups, Group A: patients presenting prior to the national lockdown date; and Group B: patients presenting after the national lockdown date. RESULTS: A total of 397 patients presented to Emergency Department with radiology confirmed urolithiasis and were included in the study. The number of patients presenting to Emergency Department with renal/ureteric colic was 285 (71.8%) patients in Group A and 112 (28.2%) patients in Group B (p<0.001). The number of patients reporting a delay in presentation was 135 (47.4%) in Group A and 63 (56.3%) in Group B (p=0.11). At presentation, there were no statistical differences between Group A and Group B regarding the serum creatinine level, C reactive protein, white blood cell count, fever, oliguria, flank pain and hydronephrosis. In addition, no significant differences were observed with the length of stay, Urology department admission requirement and type of therapy. CONCLUSION: Data from our study showed a significant reduction in presentations to Emergency Department for renal colic after the lockdown in Spain and Italy. However, we did not find any significant difference with the length of stay, Urology department admission requirement and type of therapy.

Magnetic resonance as imaging diagnostic tool in prostate cancer: New evidences-The EAU Section of Uro-Technology position. / La resonancia magnética como herramienta para el diagnóstico del cáncer de próstata: nuevas evidencias y posicionamiento de la ESUT (EAU Section of Uro-Technology).

Prostate cancer (PCa) is the second leading cause of cancer-related mortality and the most frequently diagnosed male malignant disease among men. The manifestation of PCa ranges from indolent to highly aggressive disease and due to this high variation in PCa progression, the diagnosis and subsequent treatment planning can be challenging. The current diagnostic approach with PSA testing and digital rectal examination followed by transrectal ultrasound biopsies lack in both sensitivity and specificity in PCa detection and offers limited information about the aggressiveness and stage of the cancer. Scientific work supports the rapidly growing use of multiparametric magnetic resonance imaging as the most sensitive and specific imaging tool for detection, lesion characterization and staging of PCa. Therefore, we carried out an updated review of magnetic resonance imaging in the diagnostic PCa reviewing the latest papers published in PubMed.

[Urology training in Germany: international comparison of educational concepts and satisfaction]. / Urologische Facharztausbildung im internationalen Vergleich: Wo stehen wir in Deutschland?

BACKGROUND: The training of residents in urology is challenged by global trends in surgical education, increasing technological developments, subspecialization of the field and working hour regulations for physicians. Currently, there is no standardized curriculum in Europe and significant international differences exist in the education of residents. OBJECTIVES: We aimed to comprehensively map the state of urological training in an international comparison. MATERIALS AND METHODS: A selective literature review was conducted using the following keywords: "urology, training, residents". RESULTS: Recent surveys have shown that urology training in Germany is subject to relatively few regulations on content, time and space when compared to other countries. A lack of a structured curriculum is considered as the main factor leading to dissatisfaction of the residents. Increasing work load, lack of surgical training and limited flexibility in family or research planning have been mentioned as barriers for successful training. CONCLUSION: Structured and validated competence assessments and not "minimum numbers of operations" may help improve surgical training. An objective nationwide examination at the end of residency may be useful for international benchmarking.

Current status of young urologists and residents' activity and academic training in Spain. National survey results. / Estado actual de la actividad y formación académica de residentes y urólogos jóvenes en España. Resultados de una encuesta nacional.

OBJECTIVE: To study the current status of the activity and academic training of residents and young urologists in Spain. MATERIAL AND METHODS: From the working group of residents and young urologists of the Spanish Association of Urology (AEU), an anonymous survey of 32 questions was designed. Its aim was to evaluate the academic activity of residents, defined by: number of communications to congresses, publications in national and international journals, clinical rotations within Spain and abroad, master's degree, Doctorate (PhD), applications to the European Board of Urology exam and language competences. The survey was sent via email and disseminated through social networks. RESULTS: Ninety-one respondents were obtained; 66% affirmed not having publications in scientific journals, 67% did not perform rotations abroad. Only 21% claimed to have taken the EBU exam. Only 2% of the respondents had completed a Fellowship. Although most of them (82%) had not done so, they would be interested. However, 67% of respondents believed that the relevance of academic/research activity is from high to very high. CONCLUSIONS: Our results indicate that academic activity, scientific production and publication of articles of the residents and young urologists in Spain is low. Moreover, participation in the EBU exam, the completion of a master's degree, PhD, rotations and fellowship is low. In contrast, the assessment of scientific activity is considered to be very relevant.

Scientific social media, a new way to expand knowledge. What do urologists need to know? / Las redes sociales científicas, una nueva forma de ampliar el conocimiento. ¿Qué necesitan saber los urólogos?

INTRODUCTION AND AIMS: Nowadays, it is almost impossible not to link most of the sources of modern knowledge to information of 2.0 technologies. The aim of this review is to analyse the role of scientific social media (Sc-SoMe) and its potential applications in urology. MATERIAL AND METHODS: A literature search was carried out using the PubMed database until July 2018. The research was performed with the following terms: "Social Media", "urology", "science", "research". RESULTS: Social media (SoMe) offers integrated services and easy tools for communication, collaboration and participation. Popular prototypical platforms of SoMe are Facebook, Twitter or Instagram. SoMe not only influence private life and personal communication, but these also affect business and science sectors. In this sense, the term Sc-SoMe describes the impact and usage of 2.0 technologies platforms on scientific work. There are different models of Sc-SoMe such as author identifiers which are unique identifiers that allow managing the professional identity of each researcher, distinguishing them from other researchers and unequivocally associating their work and author profiles. This helps us manage our own academic profile and control the information available about us and ensure that other researchers are finding correct and complete information about our research and career. Examples of Sc-SoMe are: ResearchGate, ORCID, Mendeley among others. CONCLUSIONS: Sc-SoMe should not only provide important information and services for literature and literature search. These could also be an important catalyst for promoting appropriate and helpful services in the context of a new concept of science, the science 2.0.
