Global Assessment of Urological Endoscopic Skills (GAUES): development and validation of a novel assessment tool to evaluate endourological skills.

OBJECTIVE: To develop and evaluate an assessment tool for endourological skills during simulation including cystoscopy, ureteroscopy (URS) and transurethral resection (TUR) procedures. METHODS: We designed a Global Assessment of Urological Endoscopic Skills (GAUES) tool, comprised of nine endourology task-specific and two global-rating skills items. The tool was developed through two rounds of the Delphi process. The GAUES tool was used to assess acquisition of URS and TUR skills of novices (Year 2 core surgical trainees, CT2) and intermediate level trainees (residents at the start of the UK higher surgical training programme in Urology, Speciality Trainee Year 3, ST3) at the Urology Simulation Boot Camp (USBC) between 2016 and 2018. Validity was evaluated by comparing scores between trainees with different levels of urological experience. Inter-rater reliability was also assessed. RESULTS: We evaluated 130 residents, 52% of trainees were at an intermediate stage of training and 39% were novices. In all, 9% of the anonymous forms were missing demographics. The completion rate of the GAUES tool during the USBC for URS and TUR was 85% and 89%, respectively. Our analysis demonstrated a significant difference in all domains between intermediates and novices at assessment in URS, except for one domain more suited to clinical assessment (P = 0.226). There was excellent intraclass correlation (ICC) overall between the two experts' judgements, ICC = 0.841 (95% confidence interval 0.767-0.893; P < 0.001, n = 88). CONCLUSIONS: We have developed the novel GAUES tool for cystoscopic, URS and TUR skills. Overall, we demonstrated good face, content and construct validity and excellent reliability, suggesting that the GAUES tool can be useful for endourological skills assessment.

Expert and Crowdsourced Evaluation of Image Quality From a Novel Endoscopy Phone Light Adapter.

OBJECTIVE: To evaluate the image quality of cystourethroscopy using a novel 3D printed phone light adapter with subject expert and crowdsourced evaluators. METHODS: A simple 3D printed light adaptor for a flexible cystoscopy was developed and made open source. Two videos were then recorded of a simulated cystourethroscopy, one using the novel adapter and the other using a traditional endoscopy light source. Expert evaluators (urology trainees and attendings) were then asked to evaluate the video quality using a double stimulus impairment scale. They were also asked to rate their level of confidence in using the novel adapter in clinical scenarios. Using Amazon's Mechanical Turk marketplace, 100 crowdsourced evaluators viewed the same videos and completed the same rating scale. The Mann-Whitney U test was then used to compare the expert and crowdsourced ratings. RESULTS: Expert and crowdsourced evaluators saw minimal degradation of video quality for the simulated urethroscopy (P= .66). However, while expert evaluators did identify degradation in the cystoscopy video, the crowdsourced evaluators did not (P = .012). 96% of the expert evaluators would either "often" or "always" use the novel adapter for difficult Foley placements and removal of ureteric stents. CONCLUSION: The novel light adapter caused minimal degradation in image quality for urethroscopy as compared to a traditional endoscopy light source, with vast majority of raters believing it would be adequate to perform common bedside cystoscopy procedures.

Low compliance to guidelines in nonmuscle-invasive bladder carcinoma: A systematic review.

PURPOSE: This systematic review assessed compliance to guidelines for the management of nonmuscle-invasive bladder carcinoma (NMIBC). METHODS: The PUBMED, Web of Science, Cochrane Library, and Scopus databases were searched in November 2019 in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis statement. RESULTS: Fifteen studies incorporating a collective total of 10,575 NMIBC patients were eligible for inclusion in this systematic review. We found that the rates of compliance were 53.0% with a single immediate intravesical instillation in patients with presumed low or intermediate risk, 37.1% with intravesical bacillus Calmette-Guerin or chemotherapy in those with intermediate risk, 43.4% with performance of a second transurethral resection in high-risk patients, 32.5% with administration of adjuvant intravesical bacillus Calmette-Guerin in high-risk patients, 36.1% with radical cystectomy in highest-risk patients, and 82.2% with cystoscopy for follow-up. CONCLUSIONS: Compliance with NMIBC guidelines remains low. Better guideline education and understanding holds the key to achieving high compliance. Strategies to improve guideline compliance at the physician level are urgently required.

Variability in adherence to guidelines based management of nonmuscle invasive bladder cancer among Society of Urologic Oncology (SUO) members.

PURPOSE: The American Urological Association (AUA) introduced evidence-based guidelines for the management of nonmuscle invasive bladder cancer (NMIBC) in 2016. We sought to assess the implementation of these guidelines among members of the Society of Urologic Oncology (SUO) with an aim to identifying addressable gaps. METHODS AND MATERIALS: An SUO approved survey was distributed to 747 members from December 28, 2018 to February 2, 2019. This 14-question online survey (Qualtrics, SAP SE, Germany) consisted of 38 individual items addressing specific statements from the AUA NMIBC guidelines within 3 broad categories - initial diagnosis, surveillance, and imaging/biomarkers. Adherence to guidelines was assessed by dichotomizing responses to each item that was related to recommended action statement within the guidelines. Statistical analysis was applied using Pearson's chi-squared test, where a P-value of <0.05 was considered statistically significant. RESULTS: A total of 121 (16.2%) members completed the survey. Members reported a mean of 71% guidelines adherence; adherence was higher for the intermediate- and high-risk subgroups (82% and 76%, respectively) compared to low-risk (58%). Specifically, adherence to guideline recommended cystoscopic surveillance intervals for low-risk disease differed based on clinical experience (60.9% [<10 years] vs. 36.8% [≥10 years], P = 0.01) and type of fellowship training (55.2% [urologic oncology] vs. 28.0% [none/other], P = 0.02). CONCLUSION: Adherence to guidelines across risk-categories was higher for intermediate- and high-risk patients. Decreased adherence observed for low-risk patients resulted in higher than recommended use of cytology, imaging, and surveillance cystoscopy. These results identify addressable gaps and provide impetus for targeted interventions to support high-value care, especially for low-risk patients.

Current Standards in the Endoscopic Management of Bladder Cancer: A Survey Evaluation among Urologists in German-Speaking Countries.

INTRODUCTION: To assess the current diagnostic, treatment, and documentation strategies for bladder cancer (BC) in German-speaking countries. MATERIALS AND METHODS: A 14-item web-based survey was distributed among members of the German, Austrian, and Swiss Associations of Urology, addressing physicians who perform cystoscopies and transurethral resection of bladder tumors (TURB). RESULTS: The survey was responded to by 308 of 5,564 urologists with a mean age of 49.5 years (response rate: 5.5%). The majority of participants (57.3%) practice in an outpatient setting. White light cystoscopy only is used by 60.2%, with additional photodynamic diagnosis and narrow band imaging by 36.8 and 12.5%, respectively. Endoscopic findings are documented in written form by 93.5%, followed by image capture (33.7%) and a central data archive (20.8%). Inpatient hospital urologists document cystoscopic findings by freehand drawing (21.4 vs. 11.4%, p = 0.017), and with a fixed bladder scheme (31.3 vs. 7.4%, <0.05) significantly more frequently. Cystoscopic findings are mainly conveyed to other health professionals in written form (77.4%), and significantly more often by inpatient urologists (p < 0.05). CONCLUSIONS: Significant differences exist in the approach to documenting and communicating cystoscopic BC findings. Accurate graphic documentation of lesions, visualization of the mucosa's totality, and meticulous consultation of previous surgical reports require improvements to reduce recurrence and progression rates.

An evaluation of the real world use and clinical utility of the Cxbladder Monitor assay in the follow-up of patients previously treated for bladder cancer.

BACKGROUND: Surveilling recurrent urothelial carcinoma (UC) requires frequent cystoscopy, which is invasive, expensive and time-consuming. An accurate urinary biomarker has the potential to reduce the number of cystoscopies required during post-treatment surveillance. OBJECTIVE: To audit the clinical utility of a new surveillance protocol incorporating the Cxbladder Monitor (CxbM) test in real-world practice. METHODS: Three hospitals implemented a new surveillance protocol. Patients were risk stratified, and then provided urine samples for CxbM testing. Low-risk CxbM-positive patients and all high-risk patients had cystoscopy at 2-3 months. Low-risk CxbM-negative patients had cystoscopy at ~ 12 months. RESULTS: 443 CxbM tests were conducted on samples from 309 patients: 257 (83.2%) low-risk and 52 (16.8%) high-risk. No pathology-confirmed recurrences were seen in low-risk CxbM-negative patients (n = 108) during the first post-CxbM cystoscopy undertaken a mean ± SD 10.3 ± 3.9 months after testing. Three recurrences were detected during cystoscopy at 2.7 ± 3.4 months in 53 low-risk CxbM-positive patients. In 49 high-risk patients, 39 (79.6%) were CxbM-negative with no pathology-confirmed recurrences. Ten high-risk patients (20.4%) were CxbM-positive with four confirmed recurrences; 2 high-grade and 2 low-grade. The median time to first cystoscopy was 12.13 (95% CI: 11.97-12.4) months in patients with a CxbM-negative result versus 1.63 (95% CI: 1.13-2.3) months in patients with a CxbM-positive result (p < 0.00001). No positive cases were missed, no patients progressed to invasive or metastatic disease, and no patient died of cancer over 35 months of follow-up. CONCLUSIONS: CxbM accurately identified a high proportion of patients (77.8%) who were safely managed with only one cystoscopy per year. Including CxbM in the protocol for patient surveillance provided clinical utility by reducing the average number of annual cystoscopies by approximately 39%, thereby sparing patients the potential discomfort and anxiety, without compromising detection rates. No advantage was observed for risk stratification prior to CxbM.

Studying the urine microbiome in superficial bladder cancer: samples obtained by midstream voiding versus cystoscopy.

BACKGROUND: Preliminary data suggest that the urinary microbiome may play a role in bladder cancer. Information regarding the most suitable method of collecting urine specimens is needed for the large population studies needed to address this. To compare microbiome metrics resulting from 16S ribosomal RNA gene sequencing between midstream, voided specimens and those obtained at cystoscopy. METHODS: Adults, with a history of superficial urothelial cell carcinoma (non-muscle invasive bladder cancer) being followed with periodic surveillance cystoscopy had a urine sample collected by a mid-stream, voided technique and then from the bladder at cystoscopy. Urine samples underwent 16S ribosomal RNA gene sequencing on the Illumina MiSeq platform. RESULTS: 22 subjects (8 female, 14 male) were included. There was no significant difference in beta diversity (diversity between samples) in all samples between collection methods. However, analysis by sex revealed a difference between voided and cystoscopy samples from the same individual in males (p = 0.006, Adonis test) but not in females (p = 0.317, Adonis test). No differences were seen by collection method in any alpha diversity (diversity within a sample) measurement or differential abundance of taxa. CONCLUSIONS: Beta diversity of the urine microbiome did differ by collection method for males only. This suggests that the urinary microbiomes of the two collection methods are not equivalent to each other, at least in males, which is the sex that bladder cancer occurs most frequently in. Therefore, the same collection method within a given study should be used.

Reducing recurrence in non-muscle-invasive bladder cancer by systematically implementing guideline-based recommendations: effect of a prospective intervention in primary bladder cancer patients.

Objective: In non-muscle-invasive bladder cancer (NMIBC), local recurrence after transurethral resection of the bladder (TURB) is common. Outcomes vary between urological centres, partly due to the sub-optimal surgical technique and insufficient application of measures recommended in the guidelines. This study evaluated early recurrence rates after primary TURB for NMIBC before and after introducing a standardized treatment protocol. Methods: Medical records of all patients undergoing primary TURB for NMIBC in 2010 at Skåne University Hospital, Malmö, Sweden, were reviewed. A new treatment protocol for NMIBC was defined and introduced in 2013, and results documented during the first year thereafter were compared with those recorded in 2010 prior to the intervention. The primary endpoint was early recurrence at first control cystoscopy. Comparisons were made by Chi-square analysis and Fisher's exact test. Recurrence-free survival (RFS) in the two cohorts was also investigated. Results: TURB was performed on 116 and 159 patients before and after the intervention, respectively. The early recurrence rate decreased from 22% to 9.6% (p = 0.005) at the first control cystoscopy after treatment. Residual/Recurrent tumour at the first control cystoscopy after the primary TURB (i.e. at second-look resection or first control cystoscopy) decreased from 31% to 20% (p = 0.038). The proportion of specimens containing muscle in T1 tumours increased from 55% to 94% (p < 0.001). RFS was improved in the intervention group (HR = 0.65, CI = 0.43-1.0; p = 0.05). Conclusions: Introduction of a standardized protocol and reducing the number of surgeons for primary treatment of NMIBC decreased the early recurrence rate from 22% to 9.6% and lowered the recurrence incidence by 35%.

French ccAFU guidelines ­ Update 2018­2020: Bladder cancer / Recommandations françaises du Comité de Cancérologie de l'AFU ­ Actualisation 2018­2020 : tumeurs de la vessie

Objective: To propose updated French guidelines for non-muscle invasive (NMIBC) and muscle-invasive (MIBC) bladder cancers. Methods: A Medline search was achieved between 2015 and 2018, as regards diagnosis, options of treatment and follow-up of bladder cancer, to evaluate different references with levels of evidence. Results: Diagnosis of NMIBC (Ta, T1, CIS) is based on a complete deep resection of the tumor. The use of fluorescence and a second-look indication are essential to improve initial diagnosis. Risks of both recurrence and progression can be estimated using the EORTC score. A stratification of patients into low, intermediate and high risk groups is pivotal for recommending adjuvant treatment: instillation of chemotherapy (immediate post-operative, standard schedule) or intravesical BCG (standard schedule and maintenance). Cystectomy is recommended in BCG-refractory patients. Extension evaluation of MIBC is based on contrast-enhanced pelvic-abdominal and thoracic CT-scan. Multiparametric MRI can be an alternative. Cystectomy associated with extended lymph nodes dissection is considered the gold standard for non-metastatic MIBC. It should be preceded by cisplatin-based neoadjuvant chemotherapy in eligible patients. An orthotopic bladder substitution should be proposed to both male and female patients with no contraindication and in cases of negative frozen urethral samples; otherwise transileal ureterostomy is recommended as urinary diversion. All patients should be included in an Early Recovery After Surgery (ERAS) protocol. For metastatic MIBC, first-line chemotherapy using platin is recommended (GC or MVAC), when performans status (PS < 1) and renal function (creatinine clearance > 60 mL/min) allow it (only in 50 % of cases). In second line treatment, immunotherapy with pembrolizumab demonstrated a significant improvement in overall survival. Conclusion: These updated French guidelines will contribute to increase the level of urological care for the diagnosis and treatment for NMIBC and MIBC.

American Urogynecologic Society Consensus Statement: Cystoscopy at the Time of Prolapse Repair.

Injury to the urinary tract is a known risk of surgical repair of anterior and apical pelvic organ prolapse. Cystoscopy at the time of surgical prolapse repair is a low-risk procedure that can identify genitourinary tract injury by inspecting the bladder and urethra as well as by visualizing the ureters and ureteral efflux. There are several techniques to assist with visualization of ureteral efflux. Identifying injury intraoperatively may allow for mitigation of the morbidity of the injury. Universal cystoscopy should be performed at the time of all pelvic reconstructive surgeries, with the exception of operations solely for posterior compartment defects.

What Is the Best Lens Angle for Rigid Diagnostic Cystoscopy? A Comparison of 30-Degree and 70-Degree Lenses.

The optimal degree of cystoscope to perform diagnostic cystoscopy is dependent on the surgeon's discretion because there are no studies addressing the superiority of one degree of cystoscope over another. The objective was to determine which lens, 70-degree versus 30-degree lens, was better in identifying lesions scattered throughout the bladder. METHODS: A simulation was created using 3 different artificial bladder models complete with sutures representing lesions placed at different locations in each bladder. Gynecologists and urologists performed cystoscopy using both the 30- and 70-degree lenses on the bladder models in a randomized and single-blinded fashion. The physicians performed routine diagnostic cystoscopy and noted the number of lesions throughout the bladder. The number of lesions each physician identified and the time to complete cystoscopy were noted. A total of 16 physicians participated, and there were a total of 18 lesions among the 3 different bladder models. RESULTS: A total of 86 cystoscopy trials were obtained from all physicians and bladder models attempted. The odds of detecting a lesion with the 70-degree lens cystoscope was 1.77 times greater than the 30-degree lens cystoscope (95% confidence interval, 1.24-2.53; P = 0.002). There was also difference in the average number of lesions found between the 30- and 70-degree cystoscopes with 2.6 ± 2.7 more lesions identified using the 70-degree cystoscope compared with the 30-degree cystoscope. In terms of specific location, 2.6 ± 1.7 more lesions were found at the bladder neck using the 70-degree lens scope versus the 30-degree lens scope (95% confidence interval, 1.37-3.83; P = 0.013). CONCLUSIONS: The results suggested that the 70-degree lens was the better choice for the identification of bladder lesions when compared with the 30-degree lens in rigid diagnostic cystoscopy.

Advancements in optical techniques and imaging in the diagnosis and management of bladder cancer.

Accurate detection and staging is critical to the appropriate management of urothelial cancer (UC). The use of advanced optical techniques during cystoscopy is becoming more widespread to prevent recurrent nonmuscle invasive bladder cancer. Standard of care for muscle-invasive UC includes the use of computed tomography and/or magnetic resonance imaging, but staging accuracy of these tests remains imperfect. Novel imaging modalities are being developed to improve current test performance. Positron emission tomography/computed tomography has a role in the initial evaluation of select patients with muscle-invasive bladder cancer and in disease recurrence in some cases. Several novel immuno-positron emission tomography tracers are currently in development to address the inadequacy of current imaging modalities for monitoring of tumor response to newer immune-based treatments. This review summaries the current standards and recent advances in optical techniques and imaging modalities in localized and metastatic UC.

Construct and Predictive Validity of a Cystoscopic Checklist to Evaluate Surgical Competency in the Operating Room.

PURPOSE: The aim of this study was to demonstrate the construct and predictive validity of a task-specific checklist for cystoscopy in the operating room. METHODS: This study is a prospective observational study evaluating the validity of a task-specific checklist for cystoscopic proficiency on residents performing cystoscopy in the operating room over a 4-year period. Residents were scored on 2 task-specific checklists: (1) assembly and (2) performance of a diagnostic cystoscopy. Construct validity was evaluated by comparing absolute checklist scores based on resident year with a Kruskal-Wallis and χ test, respectively. Paired analysis was performed with Wilcoxon sign rank and McNemar tests to assess differences between initial and final observations. Predictive validity was evaluated by determining the percent of competently performed task-specific checklists subsequent to 1 competent task-specific checklist completion. RESULTS: One hundred fifty-three evaluations were performed on 30 residents from all 4 levels of training. The median task-specific checklist scores for both (1) assembly and (2) performance of a diagnostic cystoscopy demonstrated construct validity with statistically significant trends demonstrating improved scores as resident year increased from intern to chief, P values of <0.001 and <0.0001, respectively. Once competency was obtained for 1 cystoscope assembly checklist, 92% of future assembly checklists were competently competent. For diagnostic cystoscopy once checklist competency was obtained, 69% of future checklists were completed competently. All scores and competencies were significantly improved from the initial to the final observation. DISCUSSION: The task-specific checklists for (1) assembly and (2) performance of a diagnostic cystoscopy demonstrated construct validity. Predicative validity for assembly of a cystoscope is high but less so for performance of a diagnostic cystoscope.

Defining competency in flexible cystoscopy: a novel approach using cumulative Sum analysis.

BACKGROUND: Flexible cystoscopy (FC) is one of the most frequently performed urological intervention. Cumulative sum analysis (CUSUM) allows objective assessment of a proceduralist's performance to ensure acceptable outcomes. This study investigated the application of CUSUM to assess a trainee's learning curve and maintenance of competence in performing FC. METHODS: A single urology trainee, with no previous experience of FC, performed FCs between August 2013 and February 2014. For assessment FC was divided into 5 steps. Each step was assigned a CUSUM completion score. The primary outcome measure was successful performance of a complete FC. Prospective data were collected and analysed using CUSUM. RESULTS: In total, 419 FCs were performed. Acceptable performance of FC was achieved by the 122(nd) procedure. Complete assessment of the ureteric orifices and trigone was the most difficult step of FC to achieve consistently. Competence for complete FC was achieved following 289 procedures. CONCLUSION: CUSUM analysis objectively assesses acquisition of competence in flexible cystoscopy. Recommended indicative numbers may underestimate the number of FCs trainees require to achieve, and maintain, competency. Validation of CUSUM method in a larger cohort of trainees should be considered.

Universal Cystoscopy After Benign Hysterectomy: Examining the Effects of an Institutional Policy.

OBJECTIVE: To evaluate the association between a universal cystoscopy policy at the time of benign hysterectomy and the detection of urologic injuries. METHODS: This is a retrospective cohort study at a tertiary care academic center where a policy of universal cystoscopy at the time of benign hysterectomy was instituted on October 1, 2008. Benign hysterectomies performed from March 3, 2006, to September 25, 2013, were included and dichotomized into preuniversal and postuniversal cystoscopy groups. Medical records were reviewed for baseline and perioperative characteristics, cystoscopy use, and urologic injuries related to hysterectomy. Urologic injuries were identified by using a search engine and a departmental quality improvement database. RESULTS: Two thousand nine hundred eighteen hysterectomies were identified during the study time period, 96 of which were excluded for indications of abdominopelvic cancers and peripartum indications. Therefore, 973 women were in the preuniversal cystoscopy group and 1,849 were in the postuniversal cystoscopy group. Thirty-six percent (347/973, 95% confidence interval [CI] 32.8-38.8%) and 86.1% (1,592/1,849, 95% CI 84.5-87.7%) of patients underwent cystoscopy prepolicy and postpolicy, respectively. The urologic injury rates were 2.6% (25/973, 95% CI 1.6-3.6%) and 1.8% (34/1,849, 95% CI 1.2-2.5%) in the prepolicy and postpolicy groups, respectively. Delayed urologic injuries decreased significantly (0.7% [7/973], 95% CI 0.3-1.2% compared with 0.1% [2/1,849], 95% CI 0.0-0.3%). Of the nine patients with delayed injuries, four had normal intraoperative cystoscopy findings and five had no cystoscopy performed. CONCLUSION: The practice of universal cystoscopy at the time of hysterectomy for benign indications is associated with decreased delayed postoperative urologic complications.

Decision Based on Narrow Band Imaging Cystoscopy without a Referential Normal Standard Rather Increases Unnecessary Biopsy in Detection of Recurrent Bladder Urothelial Carcinoma Early after Intravesical Instillation.

PURPOSE: The purpose of this study was to calculate the operating characteristics of narrowband imaging (NBI) cystoscopy versus traditional white light cystoscopy (WLC) in common clinical scenarios involving suspicion of bladder urothelial carcinoma (UC). MATERIALS AND METHODS: Sixty-three consecutive patients initially underwent WLC and then NBI in a single session for evaluation of microscopic hematuria (group I, n=20), gross hematuria (group II, n=19), and follow-up for prior UC (group III, n=24), by an experienced urologist. All lesions that were abnormal in contrast with adjacent normal mucosa were diagnosed as positive and biopsied. RESULTS: Sixty-six biopsies from 47 patients were performed. Pathologic examination showed 17 cases of UC from 21 sites. While the overall sensitivity of NBI was similar to that of WLC (100% vs. 94.1%), the specificity of NBI was significantly lower than that of WLC (50% vs. 86.9%, p < 0.001), particularly in group III (38.9% vs. 88.9%, p=0.004). Based on identification by NBI only, 23 additional biopsies from 18 cases were performed for identification of one patient with UC, who belonged to group III. In this group, to identify this specific patient, 15 additional biopsies were performed from 10 patients. All seven cases with positive findings from NBI within 2 months after the last intravesical therapy were histologically proven as negative. CONCLUSION: In evaluation for recurrence early after intravesical instillation, the decision based on NBI increased unnecessary biopsy in the absence of an established standard for judging NBI.

Clinical and cost effectiveness of hexaminolevulinate-guided blue-light cystoscopy: evidence review and updated expert recommendations.

CONTEXT: Non-muscle-invasive bladder cancer (NMIBC) is associated with a high recurrence risk, partly because of the persistence of lesions following transurethral resection of bladder tumour (TURBT) due to the presence of multiple lesions and the difficulty in identifying the exact extent and location of tumours using standard white-light cystoscopy (WLC). Hexaminolevulinate (HAL) is an optical-imaging agent used with blue-light cystoscopy (BLC) in NMIBC diagnosis. Increasing evidence from long-term follow-up confirms the benefits of BLC over WLC in terms of increased detection and reduced recurrence rates. OBJECTIVE: To provide updated expert guidance on the optimal use of HAL-guided cystoscopy in clinical practice to improve management of patients with NMIBC, based on a review of the most recent data on clinical and cost effectiveness and expert input. EVIDENCE ACQUISITION: PubMed and conference searches, supplemented by personal experience. EVIDENCE SYNTHESIS: Based on published data, it is recommended that BLC be used for all patients at initial TURBT to increase lesion detection and improve resection quality, thereby reducing recurrence and improving outcomes for patients. BLC is particularly useful in patients with abnormal urine cytology but no evidence of lesions on WLC, as it can detect carcinoma in situ that is difficult to visualise on WLC. In addition, personal experience of the authors indicates that HAL-guided BLC can be used as part of routine inpatient cystoscopic assessment following initial TURBT to confirm the efficacy of treatment and to identify any previously missed or recurrent tumours. Health economic modelling indicates that the use of HAL to assist primary TURBT is no more expensive than WLC alone and will result in improved quality-adjusted life-years and reduced costs over time. CONCLUSIONS: HAL-guided BLC is a clinically effective and cost-effective tool for improving NMIBC detection and management, thereby reducing the burden of disease for patients and the health care system. PATIENT SUMMARY: Blue-light cystoscopy (BLC) helps the urologist identify bladder tumours that may be difficult to see using standard white-light cystoscopy (WLC). As a result, the amount of tumour that is surgically removed is increased, and the risk of tumour recurrence is reduced. Although use of BLC means that the initial operation costs more than it would if only WLC were used, over time the total costs of managing bladder cancer are reduced because patients do not need as many additional operations for recurrent tumours.

Should antibiotics be given prior to outpatient cystoscopy? A plea to urologists to practice antibiotic stewardship.

BACKGROUND: Antimicrobial resistance is a major health problem, caused primarily by overuse of antibiotics in clinical situations in which they are not necessary. Practice guidelines recommend that antibiotics be given before outpatient cystoscopy to prevent symptomatic urinary tract infection (UTI). OBJECTIVE: To determine the frequency of febrile UTI after outpatient flexible cystoscopy in antibiotic-naive bladder tumor patients. DESIGN, SETTING, AND PARTICIPANTS: A total of 2010 consecutive outpatients with bladder tumors were entered into a prospective registry study. All patients underwent cystoscopy after they submitted a voided urine sample for culture. Significant bacteriuria was defined as >10(4) colony-forming units per milliliter with a single organism. Patients were stratified for known risk factors for UTI. INTERVENTION: Patients underwent flexible cystoscopy and received no antibiotics immediately before or after cystoscopy. They were followed for 30 d for onset of febrile UTI. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The end point was incidence of febrile UTI within 30 d of cystoscopy. Febrile UTI was defined as temperature >38°C and dysuria, or having received antibiotics from an outside physician for urinary symptoms. RESULTS AND LIMITATIONS: Of the 2010 patient cystoscopies, 489 (24%) had asymptomatic bacteriuria, and 1521 (76%) had sterile urine. Thirty-nine patients (1.9%) developed febrile UTI ≤30 d after cystoscopy-4.5% in colonized patients and 1.1% in uninfected patients (p=0.02). All UTIs resolved in ≤12-24h with oral antibiotics. None of the patients was admitted for bacterial sepsis. Limitations of the study are that it is a single-surgeon experience in one institution, and results may not apply to other patient populations. CONCLUSIONS: Antibacterial therapy before outpatient flexible cystoscopy does not appear necessary in bladder tumor patients who have no clinical signs or symptoms of acute UTI, including asymptomatic bacteriuria. Antibiotic stewardship is the responsibility of all urologists.

EAU guidelines on non-muscle-invasive urothelial carcinoma of the bladder: update 2013.

CONTEXT: The first European Association of Urology (EAU) guidelines on bladder cancer were published in 2002 [1]. Since then, the guidelines have been continuously updated. OBJECTIVE: To present the 2013 EAU guidelines on non-muscle-invasive bladder cancer (NMIBC). EVIDENCE ACQUISITION: Literature published between 2010 and 2012 on the diagnosis and treatment of NMIBC was systematically reviewed. Previous guidelines were updated, and the levels of evidence and grades of recommendation were assigned. EVIDENCE SYNTHESIS: Tumours staged as Ta, T1, or carcinoma in situ (CIS) are grouped as NMIBC. Diagnosis depends on cystoscopy and histologic evaluation of the tissue obtained by transurethral resection (TUR) in papillary tumours or by multiple bladder biopsies in CIS. In papillary lesions, a complete TUR is essential for the patient's prognosis. Where the initial resection is incomplete, where there is no muscle in the specimen, or where a high-grade or T1 tumour is detected, a second TUR should be performed within 2-6 wk. The risks of both recurrence and progression may be estimated for individual patients using the EORTC scoring system and risk tables. The stratification of patients into low-, intermediate-, and high-risk groups is pivotal to recommending adjuvant treatment. For patients with a low-risk tumour, one immediate instillation of chemotherapy is recommended. Patients with an intermediate-risk tumour should receive one immediate instillation of chemotherapy followed by 1 yr of full-dose bacillus Calmette-Guérin (BCG) intravesical immunotherapy or by further instillations of chemotherapy for a maximum of 1 yr. In patients with high-risk tumours, full-dose intravesical BCG for 1-3 yr is indicated. In patients at highest risk of tumour progression, immediate radical cystectomy should be considered. Cystectomy is recommended in BCG-refractory tumours. The long version of the guidelines is available from the EAU Web site: http://www.uroweb.org/guidelines/. CONCLUSIONS: These abridged EAU guidelines present updated information on the diagnosis and treatment of NMIBC for incorporation into clinical practice. PATIENT SUMMARY: The EAU Panel on Non-muscle Invasive Bladder Cancer released an updated version of their guidelines. Current clinical studies support patient selection into different risk groups; low, intermediate and high risk. These risk groups indicate the likelihood of the development of a new (recurrent) cancer after initial treatment (endoscopic resection) or progression to more aggressive (muscle-invasive) bladder cancer and are most important for the decision to provide chemo- or immunotherapy (bladder installations). Surgical removal of the bladder (radical cystectomy) should only be considered in patients who have failed chemo- or immunotherapy, or who are in the highest risk group for progression.
