Antimicrobial Prophylaxis in Robot-Assisted Laparoscopic Radical Prostatectomy: A Systematic Review.

It remains unclear whether antibiotic prophylaxis (AP) should be recommended or discouraged in robot-assisted laparoscopic radical prostatectomy (RALP) for prostate cancer (PCa). The development of microbial resistance and side effects are risks of antibiotic use. This systematic review (SR) investigates the evidence base for AP in RALP. A systematic literature search was conducted until 12 January 2023, using Embase, MEDLINE, Cochrane CENTRAL, Cochrane CDSR (via Ovid) and CINAHL for studies reporting the effect of AP on postoperative infectious complications in RALP. Of 436 screened publications, 8 studies comprising 6378 RALP procedures met the inclusion criteria. There was no evidence of a difference in the rate and severity of infective complications within 30 days after RALP surgery between different AP protocols. No studies omitted AP. For patients who received AP, the overall occurrence of postoperative infectious complications varied between 0.6% and 6.6%. The reported urinary tract infection (UTI) rates varied from 0.16% (4/2500) to 8.9% (15/169). Wound infections were reported in 0.46% (4/865) to 1.12% (1/89). Sepsis/bacteraemia and hyperpyrexia were registered in 0.1% (1/1084) and 1.6% (5/317), respectively. Infected lymphoceles (iLC) rates were 0.9% (3 of 317) in a RALP cohort that included 88.6% pelvic lymph node dissections (PLND), and 3% (26 of 865) in a RALP cohort where all patients underwent PLND. Our findings underscore that AP is being administered in RALP procedures without scientifically proven evidence. Prospective studies that apply consistent and uniform criteria for measuring infectious complications and antibiotic-related side effects are needed to ensure the comparability of results and guidance on AP in RALP.

Surgical techniques to preserve continence after robot-assisted radical prostatectomy.

Radical prostatectomy significantly impacts the inherent anatomy of the male pelvis and the functional mechanisms of urinary continence. Incontinence has a considerable negative influence on the quality of life of patients, as well as their social and psychological wellbeing. Numerous surgical techniques have been demonstrated to support the preservation of continence during robot-assisted radical prostatectomy (RARP). In this in-depth analysis, we give a general summary of the surgical techniques used in RARP and their impact on incontinence rates.

Photodynamic Diagnosis-guided Transurethral Resection of Bladder Tumour in Participants with a First Suspected Diagnosis of Intermediate- or High-risk Non-muscle-invasive Bladder Cancer: Cost-effectiveness Analysis Alongside a Randomised Controlled Trial.

Background: Recurrence of non-muscle-invasive bladder cancer (NMIBC) is common after transurethral resection of bladder tumour (TURBT). Photodynamic diagnosis (PDD) may reduce recurrence. PDD uses a photosensitiser in the bladder that causes the tumour to fluoresce to guide resection. PDD provides better diagnostic accuracy and allows more complete tumour resection. Objective: To estimate the economic efficiency of PDD-guided TURBT (PDD-TURBT) in comparison to white light-guided TURNT (WL-TURBT) in individuals with a suspected first diagnosis of NMIBC at intermediate or high risk of recurrence on the basis of routine visual assessment before being scheduled for TURBT. Design setting and participants: This is a health economic evaluation alongside a pragmatic, open-label, parallel-group randomised trial from a societal perspective. A total of 493 participants (aged ≥16 yr) were randomly allocated to PDD-TURBT (n = 244) or WL-TURBT (n = 249) in 22 UK National Health Service hospitals. Outcome measurements and statistical analysis: Cost effectiveness ratios were based on the use of health care resources associated with PDD-TURBT and WL-TURBT and quality-adjusted life years (QALYs) gained within the trial. Uncertainties in key parameters were assessed using sensitivity analyses. Results and limitations: On the basis of the use of resources driven by the trial protocol, the incremental cost effectiveness of PDD-TURBT in comparison to WL-TURBT was not cost saving. At 3 yr, the total cost was £12 881 for PDD-TURBT and £12 005 for WL-TURBT. QALYs at three years were 2.087 for PDD-TURBT and 2.094 for WL-TURBT. The probability that PDD-TURBT is cost effective was never >30% above the range of societal cost-effectiveness thresholds. Conclusions: There was no evidence of a difference in either costs or QALYs over 3-yr follow-up between PDD-TURBT and WL-TURBT in individuals with suspected intermediate- or high-risk NMIBC. PDD-TURBT is not supported for the management of primary intermediate- or high-risk NMIBC. Patient summary: We assessed overall costs for two approaches for removal of bladder tumours in noninvasive cancer and measured quality-adjusted life years gained for each. We found that use of a photosensitiser in the bladder was not more cost effective than use of white light only during tumour removal.

Building a Roadmap for Surveillance of Renal Masses Using a Modified Delphi Method to Help Achieve Consensus.

OBJECTIVE: To establish a consensus for initial evaluation and follow-up of patients on active surveillance (AS) for T1 renal masses (T1RM). METHODS: A modified Delphi method was used to gather information about AS of T1RM, with a focus on patient selection, timing/type of imaging modality, and triggers for intervention. A consensus panel of Michigan Urological Surgery Improvement Collaborative-affiliated urologists who routinely manage renal masses was formed. Areas of consensus (defined >80% agreement) about T1RM AS were established iteratively via 3 rounds of online questionnaires. RESULTS: Twenty-six Michigan Urological Surgery Improvement Collaborative urologists formed the panel. Consensus was achieved for 321/587 scenarios (54.7%) administered through 124 questions. Life expectancy, age, comorbidity, and renal function were most important for patient selection, with life expectancy ranking first. All tumors <3 cm and all patients with life expectancy <1 year were considered appropriate for AS. Appropriateness also increased with elevated perioperative risk, increasing tumor complexity, and/or declining renal function. Consensus was for multiphasic axial imaging initially (contrast CT for GFR >60 or MRI for GFR >30) with first repeat imaging at 3-6 months and subsequent imaging timing determined by tumor size. Consensus was for chest imaging for tumors >3 cm initially and >5 cm at follow up. Renal biopsy was not felt to be a requirement for entering AS, but useful in several scenarios. Consensus indicated rapid tumor growth as an appropriate trigger for intervention. CONCLUSION: Our consensus panel was able to achieve areas of consensus to help define a clinically useful and specific roadmap for AS of T1RM and areas for further discussion where consensus was not achieved.

Complications After Radical Cystectomy: A Systematic Review and Meta-analysis of Randomized Controlled Trials with a Meta-regression Analysis.

CONTEXT: Radical cystectomy is considered a procedure of high complexity with a relative high complication rate. OBJECTIVE: To systematically summarize the literature regarding the complications of radical cystectomy and the factors that contribute to them. EVIDENCE ACQUISITION: We searched MEDLINE/PubMed, ClinicalTrials.gov, and Cochrane Library, according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines for randomized controlled trials (RCTs) on complications related to radical cystectomy. EVIDENCE SYNTHESIS: A total of 3766 studies were screened, and 44 studies were included in this systematic review and meta-analysis. Complications following radical cystectomy are quite common. The most common complications were gastrointestinal complications (20%), infectious complications (17%), and ileus (14%). The majority of complications occurring were Clavien I-II (45%). Specific measurable patient factors are related to certain complications and can be used to stratify risk and assist in preoperative counseling, while proper design of high-quality RCTs may better reflect real-life complication rates. CONCLUSIONS: In our study, RCTs with a low risk of bias had higher complication rates than studies with a high risk of bias, underlining the need for further improvement on complication reporting in order to refine surgical outcomes. PATIENT SUMMARY: Radical cystectomy is usually followed by high complication rates, which affect patients and are, in turn, strongly associated with patients' preoperative health status.

Diagnostic Accuracy of Dynamic Sentinel Lymph Node Biopsy for Penile Cancer: A Systematic Review and Meta-analysis.

CONTEXT: A dynamic sentinel lymph node biopsy (DSNB) is used for inguinal lymph node staging in patients presenting with primary penile cancer with clinically impalpable inguinal lymph nodes (cN0). Further completion radical inguinal lymph node dissection (RLND) is offered to patients diagnosed with metastatic inguinal nodes following a DSNB. OBJECTIVE: To identify the diagnostic accuracy of a DSNB and RLND to detect lymph node metastasis. EVIDENCE ACQUISITION: A systematic literature search was performed on PubMed Medscape, EMBASE, Google Scholar, and Cochrane database for relevant studies between January 1, 2000 and April 30, 2022. Studies were included if a DSNB was offered to cN0 patients and if RLND was offered to patients with positive histology at the DSNB. Risk of bias and confounding assessments were performed. Diagnostic odds ratio, pooled sensitivity/specificity, and heterogeneity analyses were displayed. EVIDENCE SYNTHESIS: Overall, 2893 patients in the 28 studies analysed underwent a DSNB. Twenty-one studies reported patients undergoing RLND for a positive DSNB. A DSNB showed pooled weighted sensitivity of 0.87 (95% confidence interval [CI]: 0.82-0.91) and pooled log diagnostic odds ratio of 6.17 (95% CI: 5.47-6.87). A DSNB showed pooled weighted sensitivity of 0.50 (95% CI: 0.24-0.59), specificity of 0.82 (95% CI: 0.78-0.87), and a log diagnostic odds ratio of 1.18 (95% CI: 0.29-2.97) for detecting further positive lymph nodes at RLND. High heterogeneity, mostly caused by study design, characteristics of the included patients, DSNB technique used, surgical experience/centre case volumes, and follow-up schedule, represents the main limitation of this meta-analysis. Several sensitivity analyses to address these issues support our findings. CONCLUSIONS: A positive DSNB is poorly able to discriminate which patients will have further metastatic involvement at completion RLND. Better stratification of these patients would avoid unnecessary overtreatment and possible postoperative comorbidities. PATIENT SUMMARY: This analysis of the data from the published literature provides evidence that the diagnostic accuracy of a dynamic sentinel lymph node biopsy (DSNB) requires further improvement. Moreover, a high proportion of patients with a positive DSNB undergo unnecessary radical lymph node dissection; better stratification of these patients might help determine avoidable overtreatment and postoperative comorbidities.

Photodynamic versus white-light-guided resection of first-diagnosis non-muscle-invasive bladder cancer: PHOTO RCT.

BACKGROUND: Around 7500 people are diagnosed with non-muscle-invasive bladder cancer in the UK annually. Recurrence following transurethral resection of bladder tumour is common, and the intensive monitoring schedule required after initial treatment has associated costs for patients and the NHS. In photodynamic diagnosis, before transurethral resection of bladder tumour, a photosensitiser that is preferentially absorbed by tumour cells is instilled intravesically. Transurethral resection of bladder tumour is then conducted under blue light, causing the photosensitiser to fluoresce. Photodynamic diagnosis-guided transurethral resection of bladder tumour offers better diagnostic accuracy than standard white-light-guided transurethral resection of bladder tumour, potentially reducing the chance of subsequent recurrence. OBJECTIVE: The objective was to assess the clinical effectiveness and cost-effectiveness of photodynamic diagnosis-guided transurethral resection of bladder tumour. DESIGN: This was a multicentre, pragmatic, open-label, parallel-group, non-masked, superiority randomised controlled trial. Allocation was by remote web-based service, using a 1 : 1 ratio and a minimisation algorithm balanced by centre and sex. SETTING: The setting was 22 NHS hospitals. PARTICIPANTS: Patients aged ≥ 16 years with a suspected first diagnosis of high-risk non-muscle-invasive bladder cancer, no contraindications to photodynamic diagnosis and written informed consent were eligible. INTERVENTIONS: Photodynamic diagnosis-guided transurethral resection of bladder tumour and standard white-light cystoscopy transurethral resection of bladder tumour. MAIN OUTCOME MEASURES: The primary clinical outcome measure was the time to recurrence from the date of randomisation to the date of pathologically proven first recurrence (or intercurrent bladder cancer death). The primary health economic outcome was the incremental cost per quality-adjusted life-year gained at 3 years. RESULTS: We enrolled 538 participants from 22 UK hospitals between 11 November 2014 and 6 February 2018. Of these, 269 were allocated to photodynamic diagnosis and 269 were allocated to white light. A total of 112 participants were excluded from the analysis because of ineligibility (n = 5), lack of non-muscle-invasive bladder cancer diagnosis following transurethral resection of bladder tumour (n = 89) or early cystectomy (n = 18). In total, 209 photodynamic diagnosis and 217 white-light participants were included in the clinical end-point analysis population. All randomised participants were included in the cost-effectiveness analysis. Over a median follow-up period of 21 months for the photodynamic diagnosis group and 22 months for the white-light group, there were 86 recurrences (3-year recurrence-free survival rate 57.8%, 95% confidence interval 50.7% to 64.2%) in the photodynamic diagnosis group and 84 recurrences (3-year recurrence-free survival rate 61.6%, 95% confidence interval 54.7% to 67.8%) in the white-light group (hazard ratio 0.94, 95% confidence interval 0.69 to 1.28; p = 0.70). Adverse event frequency was low and similar in both groups [12 (5.7%) in the photodynamic diagnosis group vs. 12 (5.5%) in the white-light group]. At 3 years, the total cost was £12,881 for photodynamic diagnosis-guided transurethral resection of bladder tumour and £12,005 for white light. There was no evidence of differences in the use of health services or total cost at 3 years. At 3 years, the quality-adjusted life-years gain was 2.094 in the photodynamic diagnosis transurethral resection of bladder tumour group and 2.087 in the white light group. The probability that photodynamic diagnosis-guided transurethral resection of bladder tumour was cost-effective was never > 30% over the range of society's cost-effectiveness thresholds. LIMITATIONS: Fewer patients than anticipated were correctly diagnosed with intermediate- to high-risk non-muscle-invasive bladder cancer before transurethral resection of bladder tumour and the ratio of intermediate- to high-risk non-muscle-invasive bladder cancer was higher than expected, reducing the number of observed recurrences and the statistical power. CONCLUSIONS: Photodynamic diagnosis-guided transurethral resection of bladder tumour did not reduce recurrences, nor was it likely to be cost-effective compared with white light at 3 years. Photodynamic diagnosis-guided transurethral resection of bladder tumour is not supported in the management of primary intermediate- to high-risk non-muscle-invasive bladder cancer. FUTURE WORK: Further work should include the modelling of appropriate surveillance schedules and exploring predictive and prognostic biomarkers. TRIAL REGISTRATION: This trial is registered as ISRCTN84013636.

Around 7500 people are diagnosed with early-stage bladder cancer in the UK each year. Early bladder cancer is contained within the bladder and has not yet invaded the bladder's muscle wall or spread elsewhere in the body. The cancer will return (recur) in around half of people after initial treatment and they have to attend hospital for regular check-ups, with costs to both them and the NHS. The first step in treating early bladder cancer is surgery to remove the tumour. This surgery is normally performed under white light. Photodynamic diagnosis is a new technique in which a liquid is put into the patient's bladder before surgery and a blue light is used during the operation. This causes the bladder cancer to fluoresce so that it can be seen more easily by the surgeon. The Photodynamic versus white-light-guided resection of first diagnosis non-muscle-invasive bladder cancer ( PHOTO ) trial aimed to find out whether or not using photodynamic diagnosis at initial surgery would reduce how often the cancer recurred and whether or not this could reduce the cost of treating early bladder cancer. A total of 538 people with early bladder cancer who had a medium to high chance of their cancer returning after treatment were enrolled in the PHOTO trial. They were included in one of two treatment groups, at random: 269 had photodynamic surgery and 269 had standard white-light surgery. People in both groups were monitored regularly for any recurrences, with further treatment as appropriate. After 3 years, 4 out of 10 people in each group had a recurrence of their bladder cancer. We found no difference between the treatment groups in the number of people with recurrences. We found no evidence of a benefit to patients, and the total costs of photodynamic surgery were higher than those of standard white light. We therefore recommend that it is no longer used in the treatment of this group of patients.

A Randomized Trial of PHOTOdynamic Surgery in Non-Muscle-Invasive Bladder Cancer.

BACKGROUND: Recurrence of non­muscle-invasive bladder cancer (NMIBC) is common after transurethral resection of bladder tumor (TURBT). Photodynamic diagnosis (PDD) provides better diagnostic accuracy and more complete tumor resection and may reduce recurrence. However, there is limited evidence on the longer-term clinical effectiveness and cost-effectiveness of PDD-guided resection. METHODS: In this pragmatic, open-label, parallel-group randomized trial conducted in 22 U.K. National Health Service hospitals, we recruited participants with a suspected first diagnosis of NMIBC at intermediate or high risk for recurrence on the basis of routine visual assessment before being listed for TURBT. Participants were assigned (1:1) to PDD-guided TURBT or to standard white light (WL)­guided TURBT. The primary clinical outcome was time to recurrence at 3 years of follow-up, analyzed by modified intention to treat. RESULTS: A total of 538 participants were enrolled (269 in each group), and 112 participants without histologic confirmation of NMIBC or who had had cystectomy were excluded. After 44 months' median follow-up, 86 of 209 in the PDD group and 84 of 217 in the WL group had recurrences. The hazard ratio for recurrence was 0.94 (95% confidence interval [CI], 0.69 to 1.28; P=0.70). Three-year recurrence-free rates were 57.8% (95% CI, 50.7 to 64.2) and 61.6% (95% CI, 54.7 to 67.8) in the PDD and WL groups, respectively, with an absolute difference of −3.8 percentage points (95% CI, −13.37 to 5.59) favoring PDD. Adverse events occurred in less than 2% of participants, and rates were similar in both groups, as was health-related quality of life. PDD-guided TURBT was £876 (95% CI, −766 to 2518; P=0.591) more costly than WL-guided TURBT over a 3-year follow-up, with no evidence of a difference in quality-adjusted life years (−0.007; 95% CI, −0.133 to 0.119; P=0.444). CONCLUSIONS: PDD-guided TURBT did not reduce recurrence rates, nor was it cost-effective compared with WL at 3 years.

The negative aftermath of prostate biopsy: prophylaxis, complications and antimicrobial stewardship: results of the global prevalence study of infections in urology 2010-2019.

PURPOSE: To evaluate and report the complications, and to analyse antimicrobial stewardship aspects following prostate biopsies (P-Bx) based on the data from a 9-year global study. METHODS: The primary outcome was to compare complications after P-Bx between patients of two cohorts: 2010-2014 and 2016-2019. Primary outcomes included symptoms of lower and severe/systemic urinary tract infection (LUTIS and SUTIS, respectively), and positive urine culture. Readmission to hospital after P-Bx, need for additional antimicrobial therapy, consumption of different antimicrobial agents for prophylaxis and therapy were evaluated. Students t test and chi-square test were used for comparative analyses. RESULTS: Outcome data were available for 1615 men. Fluoroquinolones-based prophylaxis rate increased from 72.0% in 2010-2014 to 78.6% in 2015-2019. Overall rates of complications increased from 6 to 11.7% including an increase in symptomatic complications from 4.7 to 10.2%, mainly due to an increase in LUTIS. Rates of patients seeking additional medical help in primary care after P-Bx increased from 7.4 to 14.4%; cases requiring post P-Bx antibiotic treatment increased from 6.1 to 9.7%, most of which received fluoroquinolones. Transperineal P-Bx was significantly associated with LUTIS. Following transrectal P-Bx, 2.8% developed febrile infections and 4.0% required hospitalisation. Two men (0.12%) died after transrectal P-Bx due to sepsis. CONCLUSIONS: The rates of complications after P-Bx tended to increase in time, as well as rates of patients seeking additional medical help in the post-P-Bx period. To reduce the risk of infectious complications and to comply with the principles of antibiotic stewardship, clinicians should switch to the transperineal biopsy route.

Management of penile cancer patients during the COVID-19 pandemic: An eUROGEN accelerated Delphi consensus study.

OBJECTIVES: To develop an international consensus on managing penile cancer patients during the COVID-19 acute waves. A major concern for patients with penile cancer during the coronavirus disease 2019 (COVID-19) pandemic is how the enforced safety measures will affect their disease management. Delays in diagnosis and treatment initiation may have an impact on the extent of the primary lesion as well as the cancer-specific survival because of the development and progression of inguinal lymph node metastases. MATERIALS AND METHODS: A review of the COVID-19 literature was conducted in conjunction with analysis of current international guidelines on the management of penile cancer. Results were presented to an international panel of experts on penile cancer and infection control by a virtual accelerated Delphi process using 4 survey rounds. Consensus opinion was defined as an agreement of ≥80%, which was used to reconfigure management pathways for penile cancer. RESULTS: Limited evidence is available for delaying penile cancer management. The consensus rate of agreement was 100% that penile cancer pathways should be reconfigured, and measures should be developed to prevent perioperative nosocomial transmission of COVID-19. The panel also reached a consensus on several statements aimed at reconfiguring the management of penile cancer patients during the COVID-19 pandemic. CONCLUSIONS: The international consensus panel proposed a framework for the diagnostic and invasive therapeutic procedures for penile cancer within a low-risk environment for COVID-19.

Management of patients who opt for radical prostatectomy during the coronavirus disease 2019 (COVID-19) pandemic: an international accelerated consensus statement.

OBJECTIVE: Coronavirus disease-19 (COVID-19) pandemic caused delays in definitive treatment of patients with prostate cancer. Beyond the immediate delay a backlog for future patients is expected. The objective of this work is to develop guidance on criteria for prioritisation of surgery and reconfiguring management pathways for patients with non-metastatic prostate cancer who opt for surgical treatment. A second aim was to identify the infection prevention and control (IPC) measures to achieve a low likelihood of coronavirus disease 2019 (COVID-19) hazard if radical prostatectomy (RP) was to be carried out during the outbreak and whilst the disease is endemic. METHODS: We conducted an accelerated consensus process and systematic review of the evidence on COVID-19 and reviewed international guidance on prostate cancer. These were presented to an international prostate cancer expert panel (n = 34) through an online meeting. The consensus process underwent three rounds of survey in total. Additions to the second- and third-round surveys were formulated based on the answers and comments from the previous rounds. The Consensus opinion was defined as ≥80% agreement and this was used to reconfigure the prostate cancer pathways. RESULTS: Evidence on the delayed management of patients with prostate cancer is scarce. There was 100% agreement that prostate cancer pathways should be reconfigured and measures developed to prevent nosocomial COVID-19 for patients treated surgically. Consensus was reached on prioritisation criteria of patients for surgery and management pathways for those who have delayed treatment. IPC measures to achieve a low likelihood of nosocomial COVID-19 were coined as 'COVID-19 cold' sites. CONCLUSION: Reconfiguring management pathways for patients with prostate cancer is recommended if significant delay (>3-6 months) in surgical management is unavoidable. The mapped pathways provide guidance for such patients. The IPC processes proposed provide a framework for providing RP within an environment with low COVID-19 risk during the outbreak or when the disease remains endemic. The broader concepts could be adapted to other indications beyond prostate cancer surgery.

Condition-specific surveillance in health care-associated urinary tract infections as a strategy to improve empirical antibiotic treatment: an epidemiological modelling study.

BACKGROUND: Health care-associated urinary tract infection (HAUTI) consists of unique conditions (cystitis, pyelonephritis and urosepsis). These conditions could have different pathogen diversity and antibiotic resistance impacting on the empirical antibiotic choices. The aim of this study is to compare the estimated chances of coverage of empirical antibiotics between conditions (cystitis, pyelonephritis and urosepsis) in urology departments from Europe. METHODS: A mathematical modelling based on antibiotic susceptibility data from a point prevalence study was carried. Data were obtained for HAUTI patients from multiple urology departments in Europe from 2006 to 2017. The primary outcome of the study is the Bayesian weighted incidence syndromic antibiogram (WISCA) and Bayesian factor. Bayesian WISCA is the estimated chance of an antibiotic to cover the causative pathogens when used for first-line empirical treatment. Bayesian factor is used to compare if HAUTI conditions did or did not impact on empirical antibiotic choices. RESULTS: Bayesian WISCA of antibiotics in European urology departments from 2006 to 2017 ranged between 0.07 (cystitis, 2006, Amoxicillin) to 0.89 (pyelonephritis, 2009, Imipenem). Bayesian WISCA estimates were lowest in urosepsis. Clinical infective conditions had an impact on the Bayesian WISCA estimates (Bayesian factor > 3 in 81% of studied antibiotics). The main limitation of the study is the lack of local data. CONCLUSIONS: Our estimates illustrate that antibiotic choices can be different between HAUTI conditions. Findings can improve empirical antibiotic selection towards a personalized approach but should be validated in local surveillance studies.

Antibiotic resistance, hospitalizations, and mortality related to prostate biopsy: first report from the Norwegian Patient Registry.

BACKGROUND: A 68-year-old man died of cerebral arterial embolism 6 days after transrectal prostate biopsy with a single p.o. dose of trimethoprim sulfamethoxazole (TMP-SMX) as prophylaxis. The case precipitated analysis of local antibiotic resistance and complication rates. MATERIALS AND METHODS: Data on E. coli resistance from Oslo University Hospital and national data on hospitalizations and mortality after biopsy were retrieved from local microbiology files and the Norwegian Patient Registry (NPR) 2011-2017. RESULTS: Urine E. coli resistance against TMP-SMX increased from 35% in 2013 to more than 60% in 2015. For ciprofloxacin, the resistance increased from 15% in 2013 to about 45% in 2016. The highest annual E. coli resistance in blood cultures for TMP-SMX and ciprofloxacin was 37% and 28%, respectively. 10% of patients were hospitalized with a diagnosis of infection within the first 60 days after biopsy and there was a relative increase in mortality rate of 261% within the first 30 days. Due to the severity of the figures, the story and the NPR data were published in Norway's leading newspaper and were succeeded by a series of chronicles and commentaries. CONCLUSIONS: Several critical points of the biopsy procedure were not performed according to current standards. We believe that the patient might have died of septic embolism after biopsy. As a result of the findings and the debate, local practice was changed from transrectal to transperineal prostate biopsies.

Photodynamic versus white light-guided treatment of non-muscle invasive bladder cancer: a study protocol for a randomised trial of clinical and cost-effectiveness.

INTRODUCTION: Bladder cancer is the most frequently occurring tumour of the urinary system. Ta, T1 tumours and carcinoma in situ (CIS) are grouped as non-muscle invasive bladder cancer (NMIBC), which can be effectively treated by transurethral resection of bladder tumour (TURBT). There are limitations to the visualisation of tumours with conventional TURBT using white light illumination within the bladder. Incomplete resections occur from the failure to identify satellite lesions or the full extent of the tumour leading to recurrence and potential risk of disease progression. To improve complete resection, photodynamic diagnosis (PDD) has been proposed as a method that can enhance tumour detection and guide resection. The objective of the current research is to determine whether PDD-guided TURBT is better than conventional white light surgery and whether it is cost-effective. METHODS AND ANALYSIS: PHOTO is a pragmatic multicentre randomised controlled trial (open parallel group, non-masked and superiority trial) comparing the intervention of PDD-guided TURBT with standard white light resection in newly diagnosed intermediate and high risk NMIBC within the UK National Health Service setting. Clinical effectiveness is measured with time to recurrence. Cost-effectiveness is assessed within trial via the calculation of incremental cost per recurrence avoided and incremental cost per quality-adjusted life per year gained over 3 years and over long term through a modelling exercise over patients' lifetime. ETHICS AND DISSEMINATION: Formal ethics review was undertaken with a favourable opinion, in line with UK regulatory procedures (REC reference number: 14/NE/1062). If reductions in time to recurrence is associated with long-term patient benefits, the cost-effectiveness evaluation will provide further evidence to inform adoption of the technology. Findings will be shared in lay media such as patient and charity forums and will be presented at key meetings and published in academic literature.Trial registration number ISRCTN84013636.

Use and duration of antibiotic prophylaxis and the rate of urinary tract infection after radical cystectomy for bladder cancer: Results of a multicentric series.

OBJECTIVES: To assess the rate of urinary tract infection (UTI), the characteristics of the bacterial aetiological agents involved, the type and duration of antibiotics used, and the clinical risk factors of UTI in a multi-institutional cohort of patients who had undergone radical cystectomy (RC). PATIENTS AND METHODS: The pre- and postoperative characteristics of patients who had undergone open RC at 1 of 3 institutions between 2009 and 2015 were analyzed by means of the patient charts. Patients were classified according to the presence or absence of UTI. Analysis of the severity of UTI was based on the EAU/EAU Section of Infections in Urology (ESIU) classification system. The bacterial aetiological agents and their antibiotic susceptibility were also assessed. Factors predicting postoperative UTI were identified using univariable and multivariable logistic regression analysis. RESULTS: Of 217 patients, 42 (19.4%) had developed postoperative UTI, of whom 50% had urosepsis or uroseptic shock. Multivariable analysis showed continent urinary derivation as the only significant predictor of UTI with an odds ratio of 5.03 (95% confidence interval 2.12-11.9, P < 0.001). The duration of perioperative antibiotic prophylaxis was not associated with an increased risk of UTI. Enterococcus was the most commonly isolated bacteria (25.7%), but this species is not covered by the recommended antibiotic prophylaxis. CONCLUSION: Patients with continent urinary diversion after RC have a significantly higher risk of developing UTI. Prolonged perioperative administration of antibiotics does not seem to reduce the risk of UTI. Enterococcus as the most commonly isolated bacteria is not covered by most recommended antibiotic prophylaxis regimens. Therefore different antibiotic regimens should be considered for high-risk patients.

Transurethral Resection of the Prostate: are We Following the Guidelines? - Outcomes from the Global Prevalence of Infections in Urology (GPIU) Study.

Transurethral resection of the prostate (TURP) is one of the most common urological procedures. With the increasing rate of multiresistant infections including urosepsis, it is essential for all surgeons to adhere to the relevant international guidelines to prevent infectious complications. The aim of this prospective, multinational, multicentre study was to evaluate compliance with recommended infection control measures regarding TURP procedures. The study was performed as a side questionnaire to the annual Global Prevalence Study of Infections in Urology (GPIU) between 2006 and 2009. Patients that had undergone TURP were eligible. Baseline data about hospitals and patients were collected. The questionnaire contained questions regarding preoperative microbiological investigations, catheter care and performance of perioperative antibiotic prophylaxis. A total of 825 men were included from 138 participating centres from Africa, Asia, Europe and South America. Only 50.1% of the patients received perioperative antibiotic prophylaxis with a median duration of 3 days (interquartile range [IQR] = 1-7 days). Preoperative urine culture was taken in 59.2%. The catheter was replaced in 1 week prior to the surgery only in 38.3% of cases. Compliance with the recommended infection control measures regarding TURP were only moderate, despite high grade recommendations in relevant international Guidelines. Stronger guideline adherence is necessary to improve patient care decrease antibiotic consumption in line with antibiotic stewardship in surgical practices.

Detailed analysis of patient-reported lower urinary tract symptoms and effect on quality of life after robotic radical prostatectomy.

OBJECTIVE: To prospectively evaluate short- to medium-term patient-reported lower urinary tract symptoms (LUTS) and their effect on health-related quality of life (HRQoL) using validated questionnaires in a large cohort of patients following robotic-assisted radical prostatectomy (RARP) for prostate cancer. MATERIALS AND METHODS: HRQoL and LUTS outcomes were prospectively assessed in 357 consecutive men undergoing RARP at a single center from 2012 to 2015 using the functional assessment of cancer therapy-prostate (FACT-P) and the international consultation on incontinence modular questionnaire-male LUTS (ICIQ-MLUTS). Questionnaires were administered at baseline, 6, 12, and 18 months. Data were analyzed using paired t-tests and ANOVA. RESULTS: Questionnaire completion rates were high (over 60% of eligible men completed 18-month follow-up). Mean Total FACT-P did not significantly change after RARP: 125.95 (standard deviation [SD] = 19.82) at baseline and 125.86 (SD = 21.14) at 18-months (P = 0.55). Mean total ICIQ-MLUTS also remained unchanged: 18.69 (SD = 10.70) at baseline and 18.76 (SD = 11.33) at 18-months (P = 0.11). Mean voiding score significantly reduced from 10.34 (SD = 5.78) at baseline to 6.33 (SD = 3.99) at 6 months after RARP (P<0.001). A reciprocal significant increase in storage score was observed: 5.34 (SD = 4.26) at baseline, 9.65 (SD = 5.71) at 6 months (P<0.001). Subanalyses of ICIQ-MLUTS scores revealed increases in storage symptoms were exclusively within urinary incontinence domains and included significant increases in both urge and stress urinary incontinence scores. CONCLUSION: Overall, patient-reported outcome measures evaluating HRQoL and LUTS do not significantly change after RARP. Detailed analysis reveals significant changes within LUTS domains do occur after surgery which could be overlooked if only total LUTS scores are reported.
