Objective: To evaluate the clinical outcomes of UTUC patients with or without concurrent bladder tumor., Design, Setting, and Participants: The Clinical Research Office of the Endourology Society-Urothelial Carcinomas of the Upper Tract (CROES-UTUC) Registry included 1134 UTUC patients with or without concurrent bladder tumor treated between 2014 and 2019., Results: In 218 (19.2%) cases, concurrent bladder tumor was present, while in 916 (80.8%) patients, no bladder cancer was found. In the multivariable Cox regression analysis, concomitant bladder tumor (hazard ratio (HR) 1.562, 95% confidence interval (CI) 0.954-2.560, p = 0.076) indicated a trend associated with recurrence-free survival for UTUC. Further data dissection confirmed that concomitant bladder tumor is a risk factor of bladder recurrence (HR 1.874, 95% CI 1.104-3.183, p = 0.020) but not UTUC recurrence (HR 0.876, 95% CI 0.292-2.625, p = 0.812). Kidney-sparing surgery (KSS) (HR 3.940, 95% CI 1.352-11.486, p = 0.012), pathological T staging ≥ pT2 (HR 2.840, 95% 1.039-7.763, p = 0.042) were significantly associated with UTUC recurrence. KSS does not affect bladder recurrence (HR 0.619, 95% CI 0.242-1.580, p = 0.315). A limitation is the retrospective nature of the present study analysis., Conclusions: The presence of concomitant bladder tumor does not increase risk of UTUC recurrence, but it results in an increased risk of bladder recurrence. KSS does not affect bladder recurrence and can still be considered in patients with concomitant bladder tumor.

Context: Urinary incontinence (UI) is a common condition in elderly men causing a severe worsening of quality of life, and a significant cost for both patients and health systems., Objective: To report a practical, evidence-based, guideline on definitions, pathophysiology, diagnostic workup, and treatment options for men with different forms of UI., Evidence Acquisition: A comprehensive literature search, limited to studies representing high levels of evidence and published in the English language, was performed. Databases searched included Medline, EMBASE, and the Cochrane Libraries. A level of evidence and a grade of recommendation were assigned., Evidence Synthesis: UI can be classified into stress urinary incontinence (SUI), urge urinary incontinence (UUI), and mixed urinary incontinence. A detailed description of the pathophysiology and diagnostic workup has been reported. Simple clinical interventions, behavioural and physical modifications, and pharmacological treatments comprise the initial management for all kinds of UI. Surgery for SUI includes bulking agents, male sling, and compression devices. Surgery for UUI includes bladder wall injection of botulinum toxin A, sacral nerve stimulation, and cystoplasty/urinary diversion., Conclusions: This 2022 European Association of Urology guideline summary provides updated information on definition, pathophysiology, diagnosis, and treatment of male UI., Patient Summary: Male urinary incontinence comprises a broad subject area, much of which has been covered for the first time in the literature in a single manuscript. The European Association of Urology Non-neurogenic Male Lower Urinary Tract Symptoms Guideline Panel has released this new guidance, with the aim to provide updated information for urologists to be able to follow diagnostic and therapeutic indications for optimising patient care., (Copyright © 2022.

Objective: As the number of mobile health applications increases, quality assessment becomes a capital feature of any mobile application design. Besides the professional evaluation conducted before marketing the app, the perceptions of the subjects to whom is intended will determine the successful widespread dis- semination. Hence, the implementation of a given app may be impaired by the lack of a validated transla- tion and cross-cultural adaptation. We aimed to validate in the Turkish language the User Version of the Mobile Application Rating Scale, an English original scale designed to assess the quality of mobile health applications., Materials and Methods: A well-established and predefined process of cross-cultural adaptation and transla- tion to Turkish of the User Version of the Mobile Application Rating Scale according to the World Health Organization guidelines was performed using a common, readily available, free-of-charge application. Internal consistency and reliability were tested in a population sample by Cronbach's α and rWG index, respectively., Results: The total User Version of the Mobile Application Rating Scale score had good internal consistency (Cronbach's α = 0.87). Internal consistencies of its subscales were also acceptable: with Cronbach's α of 0.71, 0.78, 0.71, and 0.73 for engagement, functionality, aesthetics, and information, respectively. Cronbach's α of the satisfaction subscale was 0.46. The User Version of the Mobile Application Rating Scale total and sub- scales scores had a strong within-group agreement, all of them with rwg indexes between 0.78 and 0.87 over baseline to 1 month., Conclusion: The Turkish version of the User Version of the Mobile Application Rating Scale is consistent with the English original version and is a reliable and valid tool to assess the quality of mobile applications by Turkish users.

Objective: Artificial neural networks (ANNs) are widely applied in medicine, since they substantially increase the sensitivity and specificity of the diagnosis, classification, and the prognosis of a medical condition. In this study, we constructed an ANN to evaluate several parameters of extracorporeal shockwave lithotripsy (ESWL), such as the outcome and safety of the procedure., Methods: Patients with urinary lithiasis suitable for ESWL treatment were enrolled. An ANN was designed using MATLAB. Medical data were collected from all patients and 12 nodes were used as inputs. Conventional statistical analysis was also performed., Results: Finally, 716 patients were included in our study. Univariate analysis revealed that diabetes and hydronephrosis were positively correlated with ESWL complications. Regarding efficacy, univariate analysis revealed that stone location, stone size, the number and density of shockwaves delivered, and the presence of a stent in the ureter were independent factors of the ESWL outcome. This was further confirmed when adjusted for sex and age in a multivariate analysis. The performance of the ANN at the end of the training state reached 98.72%. The four basic ratios (sensitivity, specificity, positive predictive value, and negative predictive value) were calculated for both training and evaluation data sets. The performance of the ANN at the end of the evaluation state was 81.43%., Conclusion: Our ANN achieved high score in predicting the outcome and the side effects of the ESWL treatment for urinary stones., Competing Interests: The authors declare no conflict of interest., (© 2022 Editorial Office of Asian Journal of Urology.

Clinical practice guidelines (CPGs) are systematically developed statements to assist practitioners in patient decisions about appropriate health care. Appropriate methodologies and rigorous strategies are required to achieve high-quality CPGs. However, several challenges may occur during the development of guidelines. This article highlights current hot topics related to the development of guidelines for the management of non-neurogenic male lower urinary tract symptoms (LUTS) including benign prostatic obstruction (BPO). Challenges include: (1) periodic updating of guidelines because of the rapid and continuous accumulation of new evidence and a range of emerging treatment options; (2) the requirements for inclusion of new interventions in guidelines; (3) inclusion of the values and preferences of patients with LUTS who have different needs and characteristics; and (4) a need to improve guideline implementation and adherence. Actions to overcome these challenges are also discussed. PATIENT SUMMARY: Guidelines are considered to improve the quality of clinical decisions by helping doctors and contributing to the consistency of care. The development and successful translation into clinical practice of guidelines on male lower urinary tract symptoms require management of several issues, including the identification and incorporation of patients' values and preferences., (Copyright © 2022 European Association of Urology.

Purpose: White light (WL) is the traditional imaging modality for transurethral resection of bladder tumour (TURBT). IMAGE1S is a likely addition. We compare 18-mo recurrence rates following TURBT using IMAGE1S versus WL guidance., Methods: Twelve international centers conducted a single-blinded randomized controlled trial. Patients with primary and recurrent non-muscle-invasive bladder cancer (NMIBC) were randomly assigned 1:1 to TURBT guided by IMAGE1S or WL. Eighteen-month recurrence rates and subanalysis for primary/recurrent and risk groups were planned and compared by chi-square tests and survival analyses., Results: 689 patients were randomized for WL-assisted (n = 354) or IMAGE1S-assisted (n = 335) TURBT. Of these, 64.7% had a primary tumor, 35.3% a recurrent tumor, and 4.8%, 69.2% and 26.0% a low-, intermediate-, and high-risk tumor, respectively. Overall, 60 and 65 patients, respectively, completed 18-mo follow-up, with recurrence rates of 31.0% and 25.4%, respectively (p = 0.199). In patients with primary, low-/intermediate-risk tumors, recurrence rates at 18-mo were significantly higher in the WL group compared with the IMAGE1S group (31.9% and 22.3%, respectively: p 0.035). Frequency and severity of adverse events were comparable in both treatment groups. Immediate and adjuvant intravesical instillation therapy did not differ between the groups. Potential limitations included lack of uniformity of surgical resection, central pathology review, and missing data., Conclusion: There was not difference in the overall recurrence rates between IMAGE1S and WL assistance 18-mo after TURBT in patients with NMIBC. However, IMAGE1S-assisted TURBT considerably reduced the likelihood of disease recurrence in primary, low/intermediate risk patients., Registration: ClinicalTrials.gov Identifier NCT02252549 (30-09-2014)., (© 2021.

Background: The aim of this study was to assess the impact of tadalafil 5 mg/die plus tamsulosin 0.4 mg/die combination therapy on lower urinary tract symptoms (LUTS) and erectile dysfunction (ED), according to presence vs. absence of metabolic syndrome (MetS)., Methods: Seventy-five consecutive men presenting with ED and LUTS were enrolled. Patients were divided into two groups according to MetS presence. All subjects were treated with combination therapy for 12 weeks. Patients were re-evaluated after treatment with uroflowmetry and post-void residual volume (PVR), International Prostate Symptoms Score (IPSS), IPSS Quality of Life (QoL), overactive bladder questionnaire (OAB-q) and International Index Erectile Function-5 (IIEF-5) Score., Results: After enrollment, 50 patients were included: 31 (62.0%) with MetS and 19 (38.0%) without MetS. At baseline, patients without MetS showed a significantly better IPSS, IIEF and OAB-q, as compared to those with MetS. After 12 weeks of combination therapy LUTS, ED and flowmetry significantly improved in both groups (P<0.001). The improvement after 12 weeks was similar between groups in all parameters (P>0.05), except for ∆OAB-q that was significantly better for patients with MetS (P=0.028). Nevertheless, total IPSS, all IPSS subscores and OAB-q were significantly better at 12 weeks in men without MetS (P<0.05). Despite IIEF-5 was significantly different at baseline, after 12 weeks of combination therapy, erectile function was similar in men with or without METS: 16.3±3.8 vs. 17.7±4.7 (P=0.238). No serious adverse event (AE) was reported, and complications were comparable between groups (P>0.05)., Conclusions: Patients with MetS have worse LUTS and ED profiles. However, tadalafil plus tamsulosin combination treatment provided them a similar ED profile and a greater relief of overactive bladder (OAB) symptoms at the end of the trial. Combination therapy had the same safety profile in men besides MetS. Further randomized controlled trials are needed.

Background: Bladder cancer (BC) is one of the most common malignancies (4.5%of all newly diagnosed cases worldwide). Most of the new BC cases are diagnosed as non-muscle invasive BC (NMIBC), needing continuous follow up after primary endoscopic therapy. Adjuvant bladder therapy with chemo- or immuno- agents, apart from the initial diagnosis, the strict surveillance program and the risk of recurrence, may have a major impact on the patients' physical and mental health., Objective: We evaluated anxiety and quality of life (QoL) in patients who underwent surgery for NMIBC and followed a bladder instillation programme., Methods: This is a prospective analysis of patients with histopathologically confirmed NMIBCs. Eligible were all adult patients with a single or multiple NMIBCs who underwent a transurethral tumor resection and followed a therapy with either BCG or Epirubicin instillations. The SF-36 questionnaire Physical and Mental health aspects were used for QoL assessment. Similarly, the STAI-Y was introduced for the state (STAI-Y1) and trait anxiety (STAI-Y2) evaluation., Results: 117 eligible patients were screened, with 108 entering finally the study; 9 patients were excluded due to disease recurrence. 17 patients (15.7%) received Epirubicin (Ta-T1, Low Grade tumors), whereas 91 patients (84.3%) received BCG (T1, High Grade). Regarding SF-36 Physical a 6 months decrease was followed by an improvement at 12 months ( p  = 0.008). Similarly, an increase of the SF-36 Mental health score was identified ( p  = 0.03). In contrast to STAI-Y2 scores ( p  = 0.945), a long-term reduction of the state anxiety was identified ( p  = 0.001). Preoperative SF-36 Physical was inversely correlated with age ( p  = 0.029), while absence of alcohol was associated with lower mental health ( p  = 0.003). Overall, patient characteristics, habits and the administered treatment did not affect the postoperative QoL and anxiety., Conclusion: Patient QoL and anxiety improved during follow up. Still, further larger scale studies are required to support our findings., Competing Interests: Alexandros Vaioulis has no conflict of interest to report.

Purpose: To review the current data on retrograde ejaculation (RE) and ejaculatory dysfunction (EjD) after endoscopic and minimally invasive surgical treatment of benign prostatic obstruction (BPO) and, their perceived impact in the quality of life (QoL) and sexual life of patients and their partners., Methods: Narrative review of systematic reviews (SR) assessing comparative rates of RE, EjD or erectile dysfunction (EF) was carried out. Relevant articles on the prevalence of RE, EjD or EF and on their impact in the QoL or sexual life of patients and partners were manually selected based on relevance., Results: Twelve SRs reporting on comparisons of different endoscopic/minimally invasive treatments of BPO were found. Data on outcomes varied widely. Overall, after conventional TURP or laser techniques 42-75% of patients present RE. Prostatic incision and ablative procedures present lowest rates of de novo RE or EjD whereas laser adenomectomy and ejaculation preservation procedures preserve antegrade ejaculation in 46-68% of patients. EjDs is associated to LUTS and present in 10% of sexualy active men before intervention. It modulates the QoL and sexual life of the couple. In spite of the scarce literature assessing patient's and partner's perception of postoperative EjD, it strongly suggests that both parties value the maintenance of the ejaculatory function., Conclusion: Ejaculation-preserving techniques and minimally invasive techniques successfully prevent BPO treatment-induced RE or EjD in 70-100% of the cases. While this is appealing to patients and spouses, technique selection and treatment durability are issues to be discussed with the couple., (© 2021.

Objective: To conduct a prospective study of the potential prognostic role of endothelin-1 (ET-1) in a cohort of primary high-grade non-muscle-invasive urothelial bladder cancer patients, who were treated with adjuvant intravesical Bacillus Calmette-Guérin (BCG)., Material and Methods: Patients with primary high-grade nonmuscle- invasive urothelial bladder cancer, who received postoperatively induction and maintenance BCG therapy, were prospectively included. Recurrence and progression were histologically proven. Immunohistochemical staining for ET-1 was assessed. Epidemiological, pathological and clinical parameters as well as the expression of ET-1 in tumor specimens were statistically analyzed for recurrence, progression, recurrence-free survival (RFS) and progression-free survival (PFS)., Results: ET-1 associates significantly with recurrence (p = 0.000), progression (p = 0.000), RFS (p = 0.000) and PFS (p = 0.000). The patient's age is also significant for recurrence (p = 0.003, OR = 1.273 95% CI: 1.086-1.492) and RFS (p = 0.013)., Conclusions: ET-1 seems to deteriorate prognosis in patients suffering from primary high-grade non-muscle-invasive urothelial bladder cancer, who are treated with adjuvant BCG instillations. Furthermore, the patient's age associates with an increased likelihood for recurrence.

Purpose: To determine how members of the Société Internationale d'Urologie (SIU) are continuing their education in the time of COVID-19., Methods: A survey was disseminated amongst SIU members worldwide by email. Results were analyzed to examine the influence of age, practice region and settings on continuing medical education (CME) of the respondents., Results: In total, 2494 respondents completed the survey. Internet searching was the most common method of CME (76%; all ps < 0.001), followed by searching journals and textbook including the online versions (62%; all ps < 0.001). Overall, 6% of the respondents reported no time/interest for CME during the pandemic. Although most urologists report using only one platform for their CME (26.6%), the majority reported using ≥ 2 platforms, with approximately 10% of the respondents using up to 5 different platforms. Urologists < 40 years old were more likely to use online literature (69%), podcasts/AV media (38%), online CME courses/webinars (40%), and social media (39%). There were regional variations in the CME modality used but no significant difference in the number of methods by region. There was no significant difference in responses between urologists in academic/public hospitals or private practice., Conclusion: During COVID-19, urologists have used web-based learning for their CME. Internet learning and literature were the top frequently cited learning methods. Younger urologists are more likely to use all forms of digital learning methods, while older urologists prefer fewer methods.

Background: Recording the entire sexual history of a patient from the very first sexual experiences to the current sexual habits is a challenging issue that physicians usually address with partial and non-standardized interviews., Objectives: To validate the SExual Chronicle REcording Table (SECRET ® ), a structured written interview, developed and copyrighted both in English and Italian languages., Materials and Methods: A multicenter national validation study was performed asking 300 male patients affected by uro-andrological diseases to complete SECRET ® . The structured interview is based on four sexual dimensions (masturbation, oral, vaginal and anal sex), declined in seven items (1.Have you ever performed/Do you perform; 2.At what age did you first experience; 3.How many times a month; 4.With how many partners; 5.How much did/do you enjoy; 6.How many times did/do you use a condom; 7.How many times did/do you use the pull-out method). Data were stratified according to four stages of life (<30; 30-45; 45-60; >60 years old). Validity and reliability were assessed by using standard statistical methods for SECRET ® validation., Results: Overall, 295 patients (98.4%) filled all the questions. SECRET ® showed a high level of internal coherence (Cronbach's alpha coefficient ranged from 0.85 to 0.97) and reproducibility (paired sample t-test at Test-Retest: p > .10)., Conclusions: SECRET ® represents a novel, simple instrument to record a patient's sexual history in daily clinical practice and clinical research. SECRET ® has shown a good validity, internal consistence and reliability in different clusters of patients with uro-andrological diseases., (© 2020 American Society of Andrology and European Academy of Andrology.)

Background: Health sciences are steadily developing apps to help people to adopt correct lifestyles and to help physicians to monitor patients with chronic diseases. However, a properly validated tool that can evaluate patients' perception of apps is still lacking in many languages. In English, a validated questionnaire, called User Version of the Mobile Application Rating Scale (uMARS), is currently available. We translated the uMARS into Italian and validated our version., Methods: The uMARS questionnaire was translated from English to Italian by an official translator, and then administered to 100 smartphone users in order to evaluate the same app at times 1 and 2 (after 2 weeks). Paired t-test, Pearson Correlation Coefficient, Intraclass Correlation Coefficient (ICCs) and Cronbach's Alpha were used to evaluate the reliability and validity of the Italian uMARS., Results: We recruited 100 subjects, 52 males (52%) and 48 females (48%), with a mean age of 22.8 (SD: 3.4). All subjects answered all questions both at time 1 and at time 2. Paired t-test showed no statistically significant difference in each answer or group of answers between times 1 and 2 (P > 0.05). Cronbach's alpha was 0.945, as all subjects answered all questions. Each question was further assessed through the Pearson correlation coefficient, which demonstrated high reliability, with significant P (< 0.05) and Pearson Coefficients higher than 0.7. Similarly, ICCs were always higher than 0.750., Conclusions: Our results validated the Italian version of uMARS, which may become a reliable and useful tool for evaluating health apps., Competing Interests: Conflicts of interest statement The authors declare no conflict of interest., (©2021 Pacini Editore SRL, Pisa, Italy.)

Context: The role of overactive bladder (OAB) treatment in women beyond antimuscarinics has been evaluated extensively. Beta-3 agonists, botulinum toxin-A (BTX-A), and nerve stimulation are indicated in these patients. However, data on male patients in this clinical scenario are scarce., Objective: The aim of this systematic review was to evaluate the evidence on treatment options beyond antimuscarinics in men with OAB., Evidence Acquisition: A search of PubMed, EMBASE, Scopus, Web of science, Cochrane Central Register of Controlled Trials, and Cochrane Central Database of Systematic Reviews databases was performed for relevant articles published between January 2000 and October 2020, using the following Medical Subject Headings: "male/man," "LUTS," "overactive bladder," "storage symptoms," "urgency," "nocturia," "incontinence," "beta-3 agonist," "PDE-5 inhibitors," "botulinum toxin," "sacral nerve stimulation/neurostimulation," "percutaneous/transcutaneous tibial nerve stimulation," "PTENS," and "combination therapy." Evidence acquisition was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. PROSPERO registration number is CRD42020201223., Evidence Synthesis: Overall, 24 studies were retrieved. In male OAB, mirabegron (MIRA) is the most intensively investigated pharmacological option. A pooled analysis of five randomized clinical trials (RCTs), including 1187 patients, concluded that MIRA 50 mg was associated with a greater reduction in frequency versus placebo (-0.37, 95% confidence interval [CI]: -0.74, -0.01, p <  0.05). A pooled analysis of three RCTs, including 1317 male patients, has also shown that the addition of MIRA 50 mg in men receiving the α 1 -blocker tamsulosin improved the mean number of micturitions per day (-0.27, 95% CI: -0.46 to -0.09, p <  0.05), urgency episodes (-0.50, 95% CI: -0.77 to -0.22, p <  0.05), total OAB symptom score (-0.66, 95% CI: -1.00 to -0.38, p <  0.05), and mean volume voided (+10.76 ml, 95% CI: 4.87-16.64, p <  0.05). MIRA treatment is well tolerated in men. Other pharmacological treatment options, such as phosphodiesterase-5 (PDE-5) inhibitors, should be considered investigational. BTX-A seems to be effective as third-line treatment in male OAB patients. A higher rate of intermittent self-catheterization (5-42%) is observed in male than in female patients. Data on nerve stimulation are scarce., Conclusions: MIRA has the most robust data in terms of safety and efficacy in this patient population. Preliminary data in men suggest that BTX-A is indicated as an interventional treatment. Evidence for PDE-5 inhibitors and nerve stimulation is too limited to provide recommendations. Future studies in this population should aim to better define the best treatment sequence and to identify predictors for treatment response and failure, to determine a therapeutic approach tailored to patients' characteristics., Patient Summary: Overactive bladder is highly prevalent in men. Mirabegron 50 mg is the treatment option supported by the highest level of evidence when antimuscarinics failed. Botulinum toxin A injections seems to be an effective treatment as interventional option. Roles of nerve stimulation and phosphodiesterase inhibitors in male OAB patients are still to be defined., (Copyright © 2020 European Association of Urology. Published by Elsevier B.V.

Background: Safety and efficacy of tamsulosin and tadalafil for men with benign prostatic enlargement (BPE) and/or erectile dysfunction (ED) are defined. However, there are only a few pilot studies on combination therapy with these drugs for men with lower urinary tract symptom (LUTS)/BPE and ED. Moreover, preliminary reports are limited to 12 wk, without any information about subsequent therapies., Objective: To evaluate the impact of discontinuation of tamsulosin versus tadalafil 12 wk after combination therapy., Design, Setting, and Participants: Fifty consecutive patients with moderate-to-severe LUTS (International Prostate Symptom Score [IPSS] > 7) and mild-to-severe ED (International Index of Erectile Function-5 [IIEF-5] < 22) were treated with combination therapy (tamsulosin 0.4mg/d plus tadalafil 5mg/d) for 12 wk. After 12 wk, 25 patients discontinued tamsulosin (Group TAD), while 25 patients discontinued tadalafil (Group TAM)., Outcome Measurements and Statistical Analysis: Efficacy variables were IPSS (total, voiding, storage) and IIEF-5. Paired samples t test and analysis of variance were used., Results and Limitations: Groups TAD and TAM presented similar features (age, BMI, metabolic profile) including symptoms scores at baseline. Similar and significant improvements in IPSS (total, voiding, and storage) and IIEF-5 were recorded in both groups after 12 wk of combination therapy (all p< 0.001). Total IPSS was similar between the two groups at the end of the trial. However, we found between-group significant differences from baseline to 24 wk and from 12 to 24 wk in storage-IPSS (Group TAD: -3.32 vs Group TAM: -1.24, p= 0.002; Group TAD: +0.24 vs Group TAM: +1.20, p= 0.040, respectively) and in IIEF-5 (Group TAD: +4.64 vs Group TAM: +0.16, p< 0.001; Group TAD: -1.64 vs Group TAM: -4.40, p= 0.003). No significant treatment-related adverse event was recorded in both groups., Conclusions: After 12 wk of combination therapy, monotherapy with tadalafil for further 12 wk allows to preserve the improvement of storage IPSS and IIEF-5, in addition to total IPSS., Patient Summary: In this report we evaluated the discontinuation of tamsulosin or tadalafil after 12 wk of combination therapy. We found that tadalafil monotherapy, for a further 12 wk, aids in retaining the improvement of storage symptoms and erectile function., (Copyright © 2019 European Association of Urology.

Objectives: To determine the well-being of urologists worldwide during the coronavirus disease 2019 pandemic, and whether they have adequate personal protective equipment knowledge and supplies appropriate to their clinical setting., Methods: Urologists worldwide completed a Société Internationale d'Urologie online survey from 16 April 2020 until 1 May 2020. Analysis was carried out to evaluate their knowledge about protecting themselves and others in the workplace, including their confidence in their ability to remain safe at work, and any regional differences., Results: There were 3488 respondents from 109 countries. Urologists who stated they were moderately comfortable that their work environment offers good protection against coronavirus disease 2019 showed a total mean satisfaction level of 5.99 (on a "0 = not at all" to "10 = very" scale). A large majority (86.33%) were confident about protecting themselves from coronavirus disease 2019 at work. However, only about one-third reported their institution provided the required personal protective equipment (35.78%), and nearly half indicated their hospital has or had limited personal protective equipment availability (48.08%). Worldwide, a large majority of respondents answered affirmatively for testing the healthcare team (83.09%). Approximately half of the respondents (52.85%) across all regions indicated that all surgical team members face an equal risk of contracting coronavirus disease 2019 (52.85%). Nearly one-third of respondents reported that they had experienced social avoidance (28.97%)., Conclusions: Our results show that urologists lack up-to-date knowledge of preferred protocols for personal protective equipment selection and use, social distancing, and coronavirus disease 2019 testing. These data can provide insights into functional domains from which other specialties could also benefit., (© 2020 The Japanese Urological Association.)

Purpose: The perioperative management of patients who are receiving antithrombotic (antiplatelet or anticoagulant) therapy and require urologic surgery is challenging due to the inherent risk for surgical bleeding and the need to minimize thromboembolic risk. The aim of this review is to assess the quality and consistency of clinical practice guidelines (CPGs) and clinical practice recommendations (CPRs) on this topic, and to summarize the evidence and associated strength of recommendations relating to perioperative antithrombotic management., Methods: A pragmatic search of electronic databases and guidelines websites was performed to identify relevant CPGs/CPRs. The AGREE II (Appraisal of Guidelines for REsearch and Evaluation) instrument was used to assess the methodological quality and integrity of the CPGs., Results: The CPGs provided by the European Association of Urology (EAU), the American College of Chest Physicians (ACCP) and the European Society of Cardiology/European Society of Anaesthesiology (ESC/ESA), and the CPRs provided by the International Consultation on Urological Disease (ICUD)/American Urologic Association (AUA) were retrieved and reviewed. The 3 CPGs were critically assessed using the AGREE II instrument. Inconsistent recommendations were provided based on the indication for antithrombotic medication, the antiplatelet/anticoagulant agent and the type of urological procedure. Based on the AGREE II tool for CPG assessment, the EAU CPGs scored higher (83.3 points) compared to the ESC/ESA (75 points) and ACCP CPG (66.7 points)., Conclusion: The perioperative management of antithrombotic therapy in urological patients is potentially challenging but inconsistent CPG of varying quality may create uncertainty as to best practices to minimize thromboembolic and bleeding risk.

Background: Determining whether members follow guidelines, including guidelines prepared to help direct practice management during the coronavirus disease 2019 (COVID-19) pandemic, is an important goal for medical associations., Objective: To determine whether practice of urologists is in line with guidelines for the management of common urological conditions during the COVID-19 pandemic produced by leading (inter)national urological associations., Design, Setting, and Participants: Self-selected urologists completed a voluntary survey available online from March 27 to April 11, 2020 and distributed globally by the Société Internationale d'Urologie., Outcome Measurements and Statistical Analysis: Responses to two survey questions on the (1) management of 14 common urological procedures and (2) priority scoring of 10 common urological procedures were evaluated by practice setting and geographical region using chi-square and one-way analysis of variance analyses, respectively., Results and Limitations: There were 2494 respondents from 76 countries. Oncological conditions were prioritised over benign conditions, and benign conditions were deferred when feasible and safe. Oncological conditions with the greatest malignant potential were prioritised over less aggressive cancers. Respondents from Europe were least likely to postpone and most likely to prioritise conditions identified by guidelines as being of the highest priority. Respondents' priority scoring of urological procedures closely matched the priorities assigned by guidelines. The main limitation of this study is that respondents were self-selected, and access to the survey was limited by language and technology barriers., Conclusions: Prioritisation and management of urological procedures during the COVID-19 pandemic are in line with current guidelines. The greatest agreement was reported in Europe. Observed differences may be related to limited resources in some settings., Patient Summary: When deciding how best to treat patients during the coronavirus disease 2019 (COVID-19) pandemic, urologists are taking into account both expert recommendations and the availability of important local resources., (Copyright © 2020 European Association of Urology.

The coronavirus disease 2019 (COVID-19) pandemic is unlike anything seen before by modern science-based medicine. Health systems across the world are struggling to manage it. Added to this struggle are the effects of social confinement and isolation. This brings into question whether the latest guidelines are relevant in this crisis. We aim to support urologists in this difficult situation by providing tools that can facilitate decision making, and to minimise the impact and risks for both patients and health professionals delivering urological care, whenever possible. We hope that the revised recommendations will assist urologist surgeons across the globe to guide the management of urological conditions during the current COVID-19 pandemic., (Copyright © 2020.

The global impact of the 2019 novel coronavirus disease (COVID-19) pandemic on urology practice remains unknown. Self-selected urologists worldwide completed an online survey by the Société Internationale d'Urologie (SIU). A total of 2494 urologists from 76 countries responded, including 1161 (46.6%) urologists in an academic setting, 719 (28.8%) in a private practice, and 614 (24.6%) in the public sector. The largest proportion (1074 (43.1%)) were from Europe, with the remainder from East/Southeast Asia (441 (17.7%)), West/Southwest Asia (386 (15.5%)), Africa (209 (8.4%)), South America (198 (7.9%)), and North America (186 (7.5%)). An analysis of differences in responses was carried out by region and practice setting. The results reveal significant restrictions in outpatient consultation and non-emergency surgery, with nonspecific efforts towards additional precautions for preventing the spread of COVID-19 during emergency surgery. These restrictions were less notable in East/Southeast Asia. Urologists often bear the decision-making responsibility regarding access to elective surgery (40.3%). Restriction of both outpatient clinics and non-emergency surgery is considerable worldwide but is lower in East/Southeast Asia. Measures to control the spread of COVID-19 during emergency surgery are common but not specific. The pandemic has had a profound impact on urology practice. There is an urgent need to provide improved guidance for this and future pandemics.

The acronym EEP, coding for transurethral Endoscopic Enucleation of the Prostate, was introduced in 2016 by the European Association of Urology (EAU) guidelines panel on management of non-neurogenic male lower urinary tract symptoms (LUTS) and benign prostatic obstruction (BPO). Since then, a laser-based treatment, Holmium Laser Enucleation of the Prostate (HoLEP), and the current-based treatment of bipolar enucleation of the prostate (BipoLEP) are equally appreciated as valuable options for the management of benign prostatic obstruction (BPO). This was mainly inspired by the results of two meta-analyses on randomized controlled trials, comparing open prostatectomy with either Holmium Laser Enucleation of the Prostate (HoLEP) or bipolar enucleation of the prostate (BipoLEP). Prior to that, HoLEP was embraced as the only valid option for transurethral enucleation, although evidence for equivalence existed as early as 2006, but was not recognized due to a plethora of acronyms for bipolar energy-based treatments and practiced HoLEP-centrism. On the other hand, the academic discourse focused on different (other) laser approaches that came up, led by Thulium:Yttrium-Aluminum-Garnet (Tm:YAG) Vapoenucleation (ThuVEP) in 2009 and, finally, transurethral anatomical enucleation with Tm:YAG support (thulium laser enucleation of the prostate, ThuLEP) in 2010. Initially, the discourse on lasers focused on the different properties of lasers rather than technique or surgical anatomy, respectively. In and after 2016, the discussion ultimately moved towards surgical technique and accepting anatomical preparation as the common of all EEP techniques (AEEP). Since then, the unspoken question has been raised, whether lasers are still necessary to perform EEP in light of existing evidence, given the total cost of ownership (TCO) for these generators. This article weighs the current evidence and comes to the conclusion that no evidence of superiority of one modality over another exists with regard to any endpoint. Therefore, in the sense of critical importance, AEEP can be safely and effectively performed without laser technologies and without compromise.

Our aim is to present the current position of mobile health (mHealth) and the delivery of healthcare services via mobile communication devices in urology. We conducted a literature review of urology mHealth papers on PubMed. Results indicate that mHealth is becoming ubiquitous in contemporary healthcare systems. Although its potential has been shown, urology lags behind other areas, representing just 0.1% of the 300,000 available medical apps in the Apple App Store and Google Play Store. Furthermore, there is a lack of expert healthcare professional involvement in app development. To avoid harm, it is critical that the scientific accuracy, patient privacy, and user safety of urology mHealth applications are assured. This is because there is no globally enforced medical app regulation, compulsory scientific guidelines, nor mandatory industry standards. Urologists, either individually or via scientific organizations, should have a pivotal position in the design, development, review, certification, and recommendation of apps. mHealth holds great potential in urology, as it can aid multiple stakeholders: citizens, patients, healthcare professionals, health organizations, and public authorities (e.g., Ministry of Health). Even though it is mostly used to improve existing medical activities at present, the future will include revolutionary and ground-breaking technology solutions. This innovative field should be seen by urologists as an opportunity to provide greater care to our patients and better tools and knowledge to our peers.

Introduction: Prostate specific antigen and Prostate specific antigen-density are used for the initial evaluation of patient with LUTS due to benign prostatic enlargement in order to discriminate between benign conditions and prostate cancer. Conversely, the role of these markers during the follow up of benign prostatic enlargement patients is still unclear. The aim of our study is to evaluate the role of prostate specific antigen and prostate specific antigen density as outcome parameter for both medical and surgical treatment in patients with male LUTS., Evidence Acquisition: We performed a systematic review and meta-analysis based on data from clinical trials evaluating the clinical effect of medical or surgical therapy on LUTS/benign prostatic enlargement. Meta-regression analyses were done to evaluate the effects of several factors on IPSS score improvement., Evidence Synthesis: We selected 12 studies out of 433, including data on 1959 patients. Both medical and surgical treatment lead to a significant reduction of PSA levels as compared to baseline (P<0.001). However, after medical treatment, lower PSA values are associated with more significant improvements in lower urinary tract symptoms as measured with the IPSS, while after surgery (P<0.05), the recovery of urinary function does not correlate with the decline in PSA values (P=0.59). After medical treatment, the improvement in LUTS correlate with a decline of PSAD, while the opposite holds true in men treated with surgery (both: P<0.001)., Conclusions: PSAD may represent an objective treatment outcome parameter and should be evaluated during the follow up of men treated for LUTS due to BPE as marker of treatment response.

A randomized biopsy study showed that hexanic Serenoa repens (HESr) treatment resulted in prostatic inflammation reduction. This post-hoc analysis evaluated the clinical impact of HESr and investigated correlations between baseline parameters and treatment response. Patients were randomized to receive HESr 320mg/day for six months or no therapy. Assessment included International Prostate Symptoms Score (IPSS), prostate volume (PV), and maximum flow rate (Qmax). Baseline characteristics were recorded, including body mass index (BMI) and metabolic syndrome (MetS) components. In patients under α1-adrenoceptor antagonists (α1-blockers), the addition of HESr resulted in statistically significant IPSS improvement after 6 months ( p = 0.006). IPSS remained stable in patients under a1-blockers only ( p = 0.346). Patients treated only with HESr reported a significant IPSS amelioration ( p = 0.001). In the control group of naïve patients, no significant IPSS change was detected ( p = 0.298). Baseline PV showed fair correlation ( r = -0.20) with inflammation reduction in the HESr patients. BMI ( r = 0.40), diabetes mellitus ( r = 0.40), and PV ( r = 0.23) showed fair correlation with Qmax increase but without reaching statistical significance. MetS ( p = 0.06) was an influent biomarker for Qmax improvement. Treatment with HESr (as monotherapy or add-on therapy to a-blockers) may improve urinary symptoms in terms of IPSS in patients with prostatic inflammation.

Introduction: Urinary tract infections may be a severe complication after prostate biopsy. The aim of our study is to investigate the efficacy of cefixime versus prulifloxacin, as a prophylactic treatment in the era of fluoroquinolone resistance., Material and Methods: In this prospective randomized trial, patients were allocated into two groups. In Group A, patients received cefixime 400 mg p.o./day, while in Group B, prulifoxacin 600 mg p.o./day, both for three days, starting the day before procedure. Eligible for the study were men with a high prostate-specific antigen (PSA) and/or a positive rectal examination. Exclusion criteria were allergy to cefixime or fluoroquinolones, low glomerular filtration rate and drug-resistance to these antibiotics. Patients were followed-up for seven days., Results: Finally, 120 patients were divided into 2 groups of 60 patients with a mean age of 68.6 years. A total of 16 (13.3%) men had already undergone another biopsy in the past, while 18 (15%) had received prulifloxacin and 8 (6.67%) cefixime, at least once in the last three months. During follow-up, hospital admission due to a severe urinary tract infection (UTI) was required in 2 of 60 (1.3%) and 1 of 60 (1.67%) patients from Group B and A respectively. The bacterial specimens detected in those urine cultures were resistant to prulifloxacin or cefixime. Among the remaining 117 patients (97.5%), nobody presented with a UTI., Conclusions: Prophylactic cefixime could be suggested as effective in preventing severe UTIs after prostate biopsy in the era of high bacterial resistance to fluoroquinolones., Competing Interests: The authors declare no conflicts of interest., (Copyright by Polish Urological Association.)

Tadalafil 5 mg represents the standard for men with Erectile dysfunction (ED) and lower urinary tract symptoms (LUTS)/benign prostatic enlargement (BPE). We carried out an observational trial aiming to assess the efficacy and safety of Tadalafil compared with Tadalafil plus Tamsulosin. Seventy-five patients complaining of ED and LUTS were treated for 12-weeks with Tadalafil plus placebo (TAD+PLA-group) or with combination therapy tadalafil plus tamsulosin (TAD+TAM-group). Efficacy variables were: International Index of Erectile Function (IIEF), International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax) and safety assessments. Data were evaluated using paired samples T -test (baseline vs. 12-weeks) and analysis of variance (Δgroup-TAD+PLA vs. Δgroup-TAD+TAM). At baseline, both groups presented similar characteristics and symptoms scores (all: p > 0.05). From baseline to 12-weeks, all the subjects showed a significant improvement of IIEF, total-IPSS, storage-IPSS, Qmax (all: p < 0.001). Conversely, a significant improvement of voiding-IPSS was observed in TAD+TAM-group (-3.5 points, p < 0.001). Indeed, TAD+PLA-group showed a not significant improvement of voiding-IPSS (-2.0 points, p = 0.074). When we compared between-groups differences at 12-weeks, IIEF ( p = 0.255), total-IPSS ( p = 0.084) and storage-IPSS ( p = 0.08) did not show any statistically significant differences, whereas, voiding-IPSS and Qmax were significantly better in TAD+TAM-group ( p = 0.006 and p = 0.027, respectively). No severe treatment adverse events (TAEs) were reported in both groups. Tadalafil achieved the same improvements of IIEF, total-IPSS, storage-IPSS when compared to combination therapy. Instead, Qmax and voiding-IPSS were better managed with combination therapy, without change of TAEs.

β 3 -Adrenoceptors couple not only to cAMP formation but, at least in some cell types, also to alternative signaling pathways such as phosphorylation of extracellular signal-regulated kinase (ERK). β 3 -Adrenoceptor agonists are used in long-term symptomatic treatment of the overactive bladder syndrome; it is only poorly understood which signaling pathway mediates the clinical response and whether it undergoes agonist-induced desensitization. Therefore, we used human embryonic kidney cells stably transfected with human β 3 -adrenoceptors to compare coupling of ligands with various degrees of efficacy, including biased agonists, to cAMP formation and ERK phosphorylation, particularly regarding desensitization. Ligands stimulated cAMP formation with a numerical rank order of isoprenaline ≥ L 755,507 ≥ CL 316,243 > solabegron > SR 59,230 > L 748,337. Except for the weakest agonist, L 748,337, pretreatment with any ligand reduced cAMP responses to freshly added isoprenaline or forskolin to a similar extent. On the other hand, we were unable to detect ERK phosphorylation despite testing a wide variation of conditions. We conclude that a minor degree of efficacy for cAMP formation may be sufficient to induced full desensitization of that response. Transfected human embryonic kidney cells are not suitable to study desensitization of ERK phosphorylation by β 3 -adrenoceptor stimulation.

Context: A large number of minimally invasive techniques have been developed for the surgical management of male lower urinary tract symptoms (LUTS) presumed to be secondary to benign prostatic obstruction (BPO) over the last 3 decades. Many have not stood the test of time often because they were overpromoted before there were sufficient data., Objective: The scope of this paper is to consider whether new devices, for the treatment of male LUTS/BPO, have been implemented prematurely in the past. We also examine the relative certainty of evidence (CoE) that is currently available for newer developing technologies and make recommendations about the CoE that should be demanded in the future before widespread implementation., Key Messages: This evidence must provide adequate length of follow-up to allow proper information to be provided for patients before treatment choices are made and to be able to create recommendations in high-quality guidelines such as those of the European Association of Urology. It is not just within the domain of LUTS treatments that this is important, other urological devices, such as mesh devices, have been equally "guilty" and likewise devices in most other (surgical) specialities. We believe that there is a need for a set of requirements built around primary randomised controlled trials (RCTs) looking at both efficacy and safety, and secondary studies to confirm the reproducibility and generalisability of the first pivotal studies. Otherwise, there is a danger that a single pivotal study can be overexploited by device manufacturers. Studies that are needed include (1) proof of concept, (2) RCTs on efficacy and safety, as well as (3) cohort studies with a broad range of inclusion and exclusion criteria to confirm both reproducibility and generalisability of the benefits and harms. It is not the purpose of this paper to make judgements about individual treatments but simply to look at different treatments to provide verification for this debate., Patient Summary: Many new treatment devices have been developed over the last 20-30 yr, often with inadequate medium- to long-term results. Many have not stood the test of time, but were heavily promoted by manufacturers, the press, and some doctors when they were first released, meaning that many patients had unsatisfactory results. This paper proposes minimum standards for the investigation of new treatments before their widespread promotion to patients., (Copyright © 2019 European Association of Urology.

Purpose: To evaluate the effect of hexanic extract of Serenoa repens (HESr) on prostatic inflammation in patients with diagnosed prostatic inflammation., Methods: Patients with prostatic inflammation histologically confirmed by TRUS prostatic biopsy were randomized either to receive HESr (320 mg/day) or no treatment. A second biopsy was performed 6 months later according to standard clinical practice. Inflammation was assessed by the Irani's score and immunohistochemical staining using the CD3, CD4 and CD8 (for T-leucocytes), CD20 (for B-leucocytes) and CD163 (for macrophages) antibodies., Results: Overall 97 patients were eligible for analysis. In the HESr group the mean inflammation grading and aggressiveness grading score significantly decreased from 1.55 and 1.55 at baseline to 0.79 (p = 0.001) and 0.87 (p = 0.001) at the second biopsy, respectively. In the control group the mean inflammation grading score was 1.44 at first biopsy and 1.23 at the second biopsy. The mean aggressiveness gradings core was 1.09 and 0.89, respectively. No statistical significance was found (p = 0.09 and p = 0.74).The mean decrease in all inflammation scores was statistically higher in the HESr patients compared to controls. The immunohistochemical staining showed a significant change in the expression of the analyzed antibodies for the HESr patients compared to the first biopsy. In the nontreatment group, no significant difference was found at the second biopsy. The change in expression of each antibody in the HESr group was statistical significant compared to control., Conclusions: HESr seems to reduce prostatic inflammation in terms of histological and immunohistochemical parameters in this specific patients population.

Transurethral resection of the prostate (TURP) is considered the 'gold standard' for the surgical management of lower urinary tract symptoms (LUTS) due to benign prostatic obstruction (BPO). However, during recent years TURP has been challenged by several minimally invasive therapies (MITs). The reasons for the development of these MITs are the need for anesthesia and the rather unchanged morbidity of TURP, including ejaculation disorders. Mechanical MITs may represent an attractive option for treating LUTS/BPO by using mechanical forces to maintain urethral patency without cutting, ablating, heating or removing prostatic tissue. The present paper provides an update on currently available mechanical devices for the treatment of LUTS/BPO including the prostatic urethral lift (PUL), the temporary implantable nitinol device, and new intraprostatic implants. It analyzes the evidence for their safety, tolerability, and efficacy in clinical practice and aims to define those subpopulations of patients who will benefit from these MITs. It is obvious that there is a wide variation in the degree of mature of the available mechanical MITs. Time and high-quality long-term studies will decide which of these therapies will be accepted by patients and urologists. At the moment, PUL is claiming its position in the armamentarium of BPO treatment., Competing Interests: Conflict of interest statement: The authors declare that there is no conflict of interest.

To investigate the potential prognostic role of NFκB expression in primary high-grade non-muscle-invasive bladder cancer. Patients with primary high-grade non-muscle-invasive bladder cancer who received induction and maintenance BCG therapy were retrospectively included. Recurrence and progression were histologically proven. Intensity and extent of immunochemistry were assessed. The final evaluation of the NFκB staining was done by combining intensity and extent as ΄΄product΄΄ and expressing it as ΄΄low NFκΒ expression΄΄ or ΄΄high NFκB expression΄΄. Epidemiological, pathological, clinical parameters and NFκB expression were statistically analyzed for recurrence (REC), progression (PR), recurrence-free survival (RFS) and progression-free survival (PFS). NFκB is significantly associated with disease progression (p < 0,001 in univariate analysis and p = 0,001, Odds Ratio = 14,484, 95% Confidence Interval = 3187-65,821 in multivariate analysis), but not with recurrence. The median value of NFκB expression as ΄΄product΄΄ is significantly higher for the patients with progression in comparison to patients with recurrence only (p = 0,003) and patients without recurrence or progression (p = 0,001). Patients' age is significantly associated (p = 0,001 in univariate analysis and p = 0,003, Odds Ratio = 1273, 95% Confidence Interval = 1086-1492 in multivariate analysis) with disease recurrence. High NFκB expression in primary high-grade non-muscle-invasive bladder cancer, treated with postoperative intravesical BCG immunotherapy, could represent an unfavorable prognostic factor.

A systematic review and meta-analysis was carried out to evaluate the efficacy and safety of mirabegron 50 mg and 100 mg in the treatment of storage lower urinary tract symptoms/overactive bladder in comparison with a placebo and tolterodine 4 mg. A total of 491 articles were collected and eight randomized studies were identified as eligible for this meta-analysis. Overall, eight trials were included in the meta-analysis evaluating 10 248 patients. Mirabegron at both doses of 50 mg and 100 mg, and and tolterodine 4 mg were significantly associated with the reduction of incontinence episodes per 24 h, reduction of mean number of micturitions per 24 h, increase of voided volume and reduction of urgency episodes per 24 h, compared to a placebo. Both mirabegron 50 mg and mirabegron 100 mg were associated with a significant reduction of nocturia episodes when compared with a placebo. Conversely, tolterodine 4 mg did not prove to be more effective than a placebo in the reduction of nocturia episodes. Furthermore, mirabegron 50 mg showed a slightly, but significantly, better efficacy than tolterodine 4 mg in the improvement of nocturia episodes. Mirabegron 50 mg and mirabegron 100 mg shared the same risk of overall treatment-emergent adverse events rate with the placebo. Otherwise, tolterodine 4 mg was associated with a significantly greater risk than the placebo. However, mirabegron 100 mg showed a slight trend toward an increased risk of hypertension (odds ratio 1.41; P = 0.08) and cardiac arrhythmia (odds ratio 2.18; P = 0.06). Mirabegron is an effective treatment for patients with storage lower urinary tract symptoms/overactive bladder, providing a reduction of incontinence, urgency and frequency; an improvement of voided volume with a slight, but statistically, significant improvement of nocturia; with a good safety profile. These findings should be considered for the treatment planning of patients with storage lower urinary tract symptoms/overactive bladder., (© 2017 The Japanese Urological Association.)

It is well known that lower urinary tract symptoms (LUTS) have a multifactorial etiology. Therefore, there is an increased need for improved diagnostics for the optimal assessment of patients with LUTS in order to identify the various causes of symptoms and improve disease phenotyping. Research has focused on the development of improved urodynamic technologies and the development of noninvasive tests that could replace urodynamic studies. This mini-review will present the most recently published studies on the topic including new technologies in the diagnosis of bladder outlet obstruction, novel metrics for bladder sensation, analysis of filling phase rhythm, measurement of detrusor wall tension, and brain imaging during urodynamic studies., Patient Summary: Lower urinary tract symptoms (LUTS) have a multifactorial etiology; therefore there is a need for the development of new tests that can help LUTS diagnosis. The present mini-review highlights the new tests and novel concepts in the field., (Copyright © 2018. Published by Elsevier B.V.)

Storage lower urinary tract symptoms (LUTS) are characterized by an altered bladder sensation, increased daytime frequency, nocturia, urgency and urgency incontinence. Some evidence underlines the role of metabolic factors, pelvic ischemia, prostatic chronic inflammation and associated comorbidities in the pathophysiology of storage LUTS. A detailed evaluation of the severity of storage LUTS, and the concomitance of these symptoms with voiding and postmicturition symptoms, is mandatory for improving the diagnosis and personalizing treatment. A detailed medical history with comorbidities and associated risk factors, a physical examination, a comprehensive analysis of all the features of LUTS, including their impact on quality of life, and a frequency-volume chart (FVC) or bladder diary, are recommended for men with storage LUTS. Several drugs are available for the treatment of LUTS secondary to benign prostatic obstruction (BPO). Alpha-blockers (α-blockers), 5-α-reductase inhibitors and phosphodiesterase type 5 inhibitors are commonly used to manage storage LUTS occurring with voiding symptoms associated with BPO. Muscarinic receptor antagonists and Beta 3-agonists (β3-agonists) alone, or in combination with α-blockers, represent the gold standard of treatment in men with predominant storage LUTS. There is no specific recommendation regarding the best treatment options for storage LUTS after prostatic surgery., Competing Interests: Conflict of interest statement: The author(s) declared the following potential conflicts of interest with respect to the research, authorship or publication of this article: M Gacci: Consulting, honoraria, research support from Lilly, Bayer, Pfizer, Ibsa, GSK, Astellas, Pierre Fabre, Konpharma.

Context: The treatment of nocturia is a key challenge due to the multi-factorial pathophysiology of the symptom and the disparate outcome measures used in research., Objective: To assess and compare available therapy options for nocturia, in terms of symptom severity and quality of life., Evidence Acquisition: Medical databases (Embase, Medline, Cochrane Systematic Reviews, Cochrane Central) were searched with no date restriction. Comparative studies were included which studied adult men with nocturia as the primary presentation and lower urinary tract symptoms including nocturia or nocturnal polyuria. Outcomes were symptom severity, quality of life, and harms., Evidence Synthesis: We identified 44 articles. Antidiuretic therapy using dose titration was more effective than placebo in relation to nocturnal voiding frequency and duration of undisturbed sleep; baseline serum sodium is a key selection criterion. Screening for hyponatremia (< 130 mmol/l) must be undertaken at baseline, after initiation or dose titration, and during treatment. Medications to treat lower urinary tract dysfunction (α-1 adrenergic antagonists, 5-α reductase inhibitors, phosphodiesterase type 5inhibitor, antimuscarinics, beta-3 agonist, and phytotherapy) were generally not significantly better than placebo in short-term use. Benefits with combination therapies were not consistently observed. Other medications (diuretics, agents to promote sleep, nonsteroidal anti-inflammatories) were sometimes associated with response or quality of life improvement. The recommendations of the Guideline Panel are presented., Conclusions: Issues of trial design make therapy of nocturia a challenging topic. The range of contributory factors relevant in nocturia makes it desirable to identify predictors of response to guide therapy. Consistent responses were reported for titrated antidiuretic therapy. For other therapies, responses were less certain, and potentially of limited clinical benefit., Patient Summary: This review provides an overview of the current drug treatments of nocturia, which is the need to wake at night to pass urine. The symptom can be caused by several different medical conditions, and measuring its severity and impact varies in separate research studies. No single treatment deals with the symptom in all contexts, and careful assessment is essential to make suitable treatment selection., (Copyright © 2017 European Association of Urology.

The importance of assessing perioperative urine/stone cultures and providing appropriate antibiotic prophylaxis prior to shock wave lithotripsy (SWL) or endoscopic intervention cannot be minimized. Urinary tract infection (UTI) is the most common complication relating to stone intervention. Adequate assessment of culture data and adherence to appropriate guidelines may prevent the development of UTI and the potential for post-intervention urosepsis. This review outlines the current evidence for prophylaxis in the prevention of UTI and urosepsis, as well as the interpretation of stone culture data to provide an evidence-based approach for the judicious use of antibiotics in urologic stone practice.

Aims: To review and assess the definitions of drug resistance and the evidence supporting treatment for drug resistant overactive bladder/detrusor overactivity (OAB/DO)., Methods: Evidence review of the extant literature and consensus of opinion was used to derive the summary recommendations., Results: Drug resistance or drug refractory status has been inconsistently defined and reported in current evident sources. Recent publications use some correlation of lack of efficacy and or experienced side effects to define drug resistance. Algorithms based upon these definitions largely relate to the appropriate use of neuromodulation or botulinum neurotoxin, based upon patient selection and patient choice. Current treatment pathways are hampered by inability to consistently profile patients to optimize management, particularly after failure of initial pragmatic treatment., Conclusions: Further research is recommended to better identify patient phenotype for purposes of directing optimized therapy for OAB/DO. Current treatment algorithms are influenced by extensive data generated from recent neuromodulation and botulinum neurotoxin trials., (© 2017 Wiley Periodicals, Inc.)

Context: Several noninvasive tests have been developed for diagnosing bladder outlet obstruction (BOO) in men to avoid the burden and morbidity associated with invasive urodynamics. The diagnostic accuracy of these tests, however, remains uncertain., Objective: To systematically review available evidence regarding the diagnostic accuracy of noninvasive tests in diagnosing BOO in men with lower urinary tract symptoms (LUTS) using a pressure-flow study as the reference standard., Evidence Acquisition: The EMBASE, MEDLINE, Cochrane Database of Systematic Reviews, Cochrane Central, Google Scholar, and WHO International Clinical Trials Registry Platform Search Portal databases were searched up to May 18, 2016. All studies reporting diagnostic accuracy for noninvasive tests for BOO or detrusor underactivity in men with LUTS compared to pressure-flow studies were included. Two reviewers independently screened all articles, searched the reference lists of retrieved articles, and performed the data extraction. The quality of evidence and risk of bias were assessed using the QUADAS-2 tool., Evidence Synthesis: The search yielded 2774 potentially relevant reports. After screening titles and abstracts, 53 reports were retrieved for full-text screening, of which 42 (recruiting a total of 4444 patients) were eligible. Overall, the results were predominantly based on findings from nonrandomised experimental studies and, within the limits of such study designs, the quality of evidence was typically moderate across the literature. Differences in noninvasive test threshold values and variations in the urodynamic definition of BOO between studies limited the comparability of the data. Detrusor wall thickness (median sensitivity 82%, specificity 92%), near-infrared spectroscopy (median sensitivity 85%, specificity 87%), and the penile cuff test (median sensitivity 88%, specificity 75%) were all found to have high sensitivity and specificity in diagnosing BOO. Uroflowmetry with a maximum flow rate of <10ml/s was reported to have lower median sensitivity and specificity of 68% and 70%, respectively. Intravesical prostatic protrusion of >10mm was reported to have similar diagnostic accuracy, with median sensitivity of 68% and specificity of 75%., Conclusions: According to the literature, a number of noninvasive tests have high sensitivity and specificity in diagnosing BOO in men. However, although the majority of studies have a low overall risk of bias, the available evidence is limited by heterogeneity. While several tests have shown promising results regarding noninvasive assessment of BOO, invasive urodynamics remain the gold standard., Patient Summary: Urodynamics is an accurate but potentially uncomfortable test for patients in diagnosing bladder problems such as obstruction. We performed a thorough and comprehensive review of the literature to determine if there were less uncomfortable but equally effective alternatives to urodynamics for diagnosing bladder problems. We found that some simple tests appear to be promising, although they are not as accurate. Further research is needed before these tests are routinely used in place of urodynamics., (Copyright © 2016 European Association of Urology. Published by Elsevier B.V. All rights reserved.)

Context: The correlation among metabolic syndrome, lower urinary tract symptoms (LUTS), and cardiovascular disease (CVD) is well established. In particular, CVD has been proposed as a potential risk factor for both LUTS progression and severity., Objective: To evaluate whether LUTS severity can be considered as a significant risk factor of major adverse cardiac events (MACE) in the male population., Evidence Acquisition: A systematic literature search was performed using PubMed, Google Scholar, and Scopus. The combination of the following keywords was adopted in a free-text strategy: benign prostatic hyperplasia (BPH) or lower urinary tract symptoms (LUTS) and cardiovascular, cardio, major adverse cardiac events, MACE, heart disease, heart, myocardial infarction, myocardial, infarction, stroke, ischemic events, ischemic, cardiac death, coronary syndrome. We included all cross-sectional and longitudinal trials enrolling men and comparing the prevalence or incidence of MACE in men with moderate to severe LUTS compared with those without LUTS or with mild LUTS. The studies in which only nocturia was evaluated were excluded from the analysis., Evidence Synthesis: Of 477 retrieved articles, 5 trials longitudinally reported the incidence of MACE in patients with moderate to severe LUTS in comparisons to those with mild or no LUTS and 10 studies reported the prevalence of history of MACE at enrollment. All were included in the present meta-analysis. Among cross-sectional studies, 38 218 patients and 2527 MACE were included in the meta-analysis. The mean age of enrolled patients was 62.2±8.0 yr. Presence of moderate to severe LUTS significantly increased the risk of reported history of MACE (p<0.001). Metaregression analyses showed that the risk of MACE was lower in older patients and higher in those with diabetes. The association between LUTS-related MACE and diabetes was confirmed in a multivariate regression model after adjusting for age (adjusted r=0.498; p<0.0001). Longitudinal trials included 25 494 patients and 2291 MACE. The mean age of enrolled patients was 52.5±5.5 yr, and mean follow-up was 86.8±22.1 mo. Presence of moderate to severe LUTS was associated with an increased incidence of MACE compared with the rest of the sample (odds ratio: 1.68; 95% confidence interval, 1.13-2.50; p=0.01)., Conclusions: Men with moderate to severe LUTS seem to have an increased risk of MACE. A holistic approach in considering the morbidities of aging men should be strongly encouraged and represents an important role for the practicing urologist., Patient Summary: We evaluated whether the severity of lower urinary tract symptoms could be considered as a significant risk factor for major adverse cardiac events (MACE) in the male population. We demonstrated that men with moderate to severe LUTS have an increased risk of MACE., (Copyright © 2016 European Association of Urology. Published by Elsevier B.V. All rights reserved.)

Purpose: To evaluate the efficacy of meropenem single dose before transrectal prostate biopsy, instead of ciprofloxacin in the era of fluoroquinolones resistance., Methods: This prospective study included patients with indications for prostatic biopsy from January to December 2014. Those with known resistance in fluoroquinolones or meropenem or with decreased creatinine clearance were excluded. Patients were randomized into two groups, and statistical analysis was carried out. Group A received a 3-day course of ciprofloxacin 500 bid per os starting the day before biopsy. Group B received 1 g meropenem intravenously 1 h prior to the procedure. Patients were followed up for 15 days, and those with lower urinary tract symptoms (LUTS) and fever were called for hospitalization. Urine and blood cultures were obtained., Results: A total of 110 patients, 52-75 years old (mean 67.5, median 66) participated in the study, allocated in Groups A and B. After the procedure, 18 patients (32.7 %) of Group A reported macroscopic hematuria, while 10 (18.2 %) reported rectal blood loss. Nine patients (16.3 %) presented because of fever and LUTS. One of them developed septic shock and died in the ICU. Cultures revealed multi-resistant E. coli with high sensitivity to meropenem, and patients were treated accordingly. In Group B, 20 (36.3 %) patients presented with macroscopic hematuria and 9 (16.3 %) with rectal blood loss. One patient returned to hospital with LUTS and fever. Cultures revealed Klebsiella pneumoniae sensitive to colimycine., Conclusions: A single dose of meropenem prior to prostate biopsy is a safe and effective way to avoid the possible infectious complications in high-risk patients.

Background: After radiotherapy (RT) for prostate cancer (PCa), several patients reported lower urinary tract symptoms (LUTS) due to damage and discontinuation of the glycosaminoglycan layer of the bladder. Instillation of hyaluronic acid and chondroitin sulfate (HA-CS) represents replenishment therapy of the glycosaminoglycan layer. The aim of the study is to evaluate the efficacy and safety of HA-CS in men with symptomatic cystitis after RT for PCa., Materials and Methods: Eighty consecutive men were treated with RT for PCa; 30 of these (37.5%) reported clinically relevant LUTS and associated bother as measured by the Interstitial Cystitis Symptom Index and Problem Index (ICSI/ICPI) Questionnaire 3 months after RT. Symptomatic patients received instillation therapy with HA-CS weekly for the first month and then at weeks 6, 8, and 12. All patients completed the ICSI/ICPI questionnaire before and after RT and at the end of HA-CS treatment., Results: HA-CS significantly reduced postradiation LUTS (P < .001) and bother (P = .006). Age, Gleason score, and radiation dose were the main determinants of worsening of LUTS after radiation (ICSI score baseline vs. postradiation: P = .047, .043, and .023). In multivariate analysis, only age influenced LUTS worsening after RT (P = .01). Age, radiation dose, and radiation toxicity were related to recovery of LUTS (ICSI score postradiation vs. post-HA-CS P = .041, P = .050, and P = .046). In multivariate analysis, no factor was statistically significant., Conclusions: A remarkable worsening of symptoms and bother was observed after RT. HA-CS instillation is a safe treatment and resulted in an improvement of LUTS irrespective of age and clinical features, with full recovery of urinary bother., (Copyright © 2016 Elsevier Inc.

In the developed and developing countries, the overall prevalence of central obesity in the elderly men is growing. In addition, the progressive aging of male population increased the possibilities of coexisting morbidities associated with obesity such as lower urinary tract symptoms (LUTS) due to benign prostatic enlargement (BPE) or to prostate cancer (PCa) needing primary treatment, including radical prostatectomy (RP), which can further adversely affect the quality of life. Simple and radical prostatectomy are the most common surgical procedures in urologic unit all over the world for BPE and PCa, respectively. After both interventions, patients can present bothering storage LUTS that can worsen all the other clinical outcomes. Preset study will review the role of central obesity as a risk factor for storage LUTS or urinary incontinence, after prostatic surgery for BPE or PCa.
