Keep it Simple: A Proposal for a New Definition of Uncomplicated and Complicated Urinary Tract Infections from the EAU Urological Infections Guidelines Panel

The European Association of Urology Urological Infections Guidelines Panel is proposing a new classification scheme for categorizing urinary tract infections (UTIs) into uncomplicated and complicated types. This classification would provide clarity and facilitate effective clinical management of UTIs, and acknowledges the importance of addressing clinical and sex-specific nuances in the care of individual patients.

European Association of Urology Guidelines on Urological Infections: Summary of the 2024 Guidelines

BACKGROUND AND OBJECTIVE

Urological infections significantly impact the wellbeing and quality of life of individuals owing to their widespread occurrence and diverse clinical manifestations. The objective of the guidelines panel was to provide evidence-based guidance on the diagnosis, treatment, and prevention of urinary tract infections (UTIs) and male accessory-gland infections, while addressing crucial public health aspects related to infection control and antimicrobial stewardship.

METHODS

For the 2024 guidelines on urological infections, new and relevant evidence was identified, collated, and appraised via a structured assessment of the literature. Databases searched included Medline, EMBASE, and the Cochrane Libraries. Recommendations within the guidelines were developed by the panel to prioritise clinically important care decisions. The strength of each recommendation was determined according to a balance between desirable and undesirable consequences of alternative management strategies, the quality of the evidence (including the certainty of estimates), and the nature and variability of patient values and preferences.

KEY FINDINGS AND LIMITATIONS

Key recommendations emphasise the importance of a thorough medical history and physical examination for patients with urological infections. The guidelines stress the role of antimicrobial stewardship to combat the rising threat of antimicrobial resistance, providing recommendations for antibiotic selection, dosing, and duration on the basis of the latest evidence.

CONCLUSIONS AND CLINICAL IMPLICATIONS

This overview of the 2024 EAU guidelines offers valuable insights into managing urological infections and are designed for effective integration into clinical practice.

PATIENT SUMMARY

The European Association of Urology has issued an updated guideline on urological infections. The guidelines provide recommendations for diagnosis, treatment, and prevention, with a particular focus on minimising antibiotic use because of the increasing global threat of antimicrobial resistance.

Again and Again-Survival of Candida albicans in Urine Containing Antifungals

BACKGROUND

Relapse of Candida albicans urinary tract infection (UTI) is frequent despite appropriate treatment, as commonly used antifungals such fluconazole and flucytosine are only fungistatics. To improve treatment of Candida UTI and decrease relapses, understanding the long-term metabolic activity and survival of C. albicans in urine containing antifungals at minimal inhibitory concentration (MIC) is needed.

METHODS

we monitored the survival, metabolic activity and consumption of glucose and proteins by C. albicans using conventional methods and isothermal microcalorimetry (IMC). We also investigated the influence of dead Candida cells on the growth of their living counterparts.

RESULTS

For 33 days, weak activity was observed in samples containing antifungals in which C. albicans growth rate was reduced by 48%, 60% and 88%, and the lag increased to 172 h, 168 h and 6 h for amphotericin, flucytosine and fluconazole, respectively. The metabolic activity peaks corresponded to the plate counts but were delayed compared to the exhaustion of resources. The presence of dead cells promoted growth in artificial urine, increasing growth rate and reducing lag in similar proportions.

CONCLUSIONS

Even with antifungal treatment, C. albicans relapses are possible. The low metabolic activity of surviving cells leading to regrowth and chlamydospore formation possibly supported by autophagy are likely important factors in relapses.

Genitourinary Tuberculosis: A Brief Manual for Urologists on Diagnosis and Treatment from the European Association of Urology Urological Infections Panel

Although tuberculosis (TB) ranks among the most frequent infectious diseases worldwide, one of its extrapulmonary (EP) manifestations, genitourinary (GU) TB, is often underestimated by urologists, particularly in areas such as Europe where TB is not endemic. The aim of this review is to give urologists a concise overview of GUTB as a supplement to the more comprehensive European Association of Urology 2023 update on urological infections guidelines. EPTB can develop in 16% of TB cases. GUTB accounts for 4.6% of EPTB and is often asymptomatic or nonspecific, so it can be confused with other urogenital diseases. GUTB can be highly destructive, leading to failure of urogenital organs. Diagnosis is via microbiological, molecular, and histological testing for urine, genital secretions, or genitourinary tissue, supported by imaging. A 6-mo combinational medical regimen is the first-line treatment for GUTB. However, surgical interventions are also frequently required for the treatment of GUTB complications. Therefore, it is important to keep GUTB in mind for differential diagnosis. PATIENT SUMMARY: We reviewed scientific studies on the occurrence, diagnosis, and treatment of tuberculosis in the genitourinary tract. Our aim is to raise awareness among urologists from countries where this disease does not occur frequently, as urogenital tuberculosis can occur without any symptoms or with unspecific symptoms that can be confused with other diseases.

[Prostate biopsy-infection prophylaxis and patient preparation]

Prostate biopsy has been at the center of controversy in recent years due to high infection complications associated with the transrectal route and the withdrawal of authorization for fluoroquinolones and fosfomycin trometemol as prophylaxis. The Urological Infections Guideline Group of the European Association of Urology (EAU) recently published a meta-analysis in two parts based on randomized controlled trials (RCTs) and annually updates the data for the EAU guidelines. The meta-analyses show that transperineal prostate biopsy is associated with significantly fewer infectious complications than transrectal biopsy and should therefore be preferred. If transrectal biopsy is still used, then intrarectal cleansing with povidone-iodine and antibiotic prophylaxis should be used. Antibiotic prophylaxis strategies include targeted prophylaxis after sensitivity testing of the rectal flora, augmented prophylaxis with several antibiotics and empirical monoprophylaxis. Data from RCTs are available for aminoglycosides and third-generation cephalosporins.

The efficacy and tolerability of pollen extract in combination with hyaluronic acid and vitamins in the management of patients affected by chronic prostatitis/chronic pelvic pain syndrome: a 26 weeks, randomized, controlled, single-blinded, phase III study

BACKGROUND

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) remains a challenging clinical condition to manage. Here, we evaluate the efficacy and tolerability of a new treatment option (suppositories) containing pollen extract in combination with hyaluronic acid and vitamins in the management of patients with CP/CPPS.

METHODS

In this prospective, randomized, controlled, single-blinded, phase-III study we enrolled CP/CPPS patients between March and December 2019. Participants were randomized (1:1) to the following treatment groups: 1) pollen extract suppositories 1 daily for 10 days; or 2) ibuprofen 600 mg 1 tablet in the morning for 10 days. At the enrolment time and at the follow-up evaluations (3, 6 months), all patients completed baseline questionnaires ([National Institutes of Health Chronic Prostatitis Symptom Index [NIH-CPSI] and Quality of Well-Being [QoL]) and underwent urological examination and microbiological evaluation. The primary endpoint was the quality-of-life assessment with Patients' Reported Outcomes (PROs).

RESULTS

One hundred and eighty-seven patients were screened. Finally, one hundred and twenty-four patients (mean age 34.6±3.9 years) were randomly allocated to the new pollen extract treatment (N.=63) or ibuprofen (N.=61) groups. At the end of follow-up examinations 56/63 group 1 patients (88.8%) showed a significant reduction of the NIH-CPSI total score, compared with 17/61 (27.8%) in group 2 (P<0.0001). Group 1 patients also reported a higher improvement in terms of PROs, when compared with the control group and group 1 patients reported a significant reduction of leucocyte count at the Meares-Stamey Test (-12; -4; P<0.001). Only mild adverse events were reported in the two groups and adverse events were less frequent in the pollen extract suppositories group.

CONCLUSIONS

The combination of pollen extract with hyaluronic acid and vitamins is more effective than ibuprofen in improving symptoms and Quality of Life in patients affected with CP/CPPS and has less side effects.

Adherence to European Association of Urology Guidelines and State of the Art of Glycosaminoglycan Therapy for the Management of Urinary Tract Infections: A Narrative Review and Expert Meeting Report

Context

Urinary tract infections (UTIs) have a significant impact on patient's quality of life and society. Antibiotic therapy is the primary approach for the management of UTIs; however, it has major limits in the prevention of recurrent UTIs (rUTIs), also increasing the risk of development of multidrug-resistant micro-organisms.

Objective

The aim of this paper is to discuss the European Association of Urology guidelines for the management of UTIs/rUTIs, the level of adherence to these recommendations, and the available evidence on the use of glycosaminoglycans (GAGs) as a possible alternative treatment to prevent rUTIs.

Evidence acquisition

This narrative review and expert meeting report is based on a literature search concerning the currently available UTI guidelines, the results of a survey administered to 227 urologists, and the opinion of an expert panel in the field of UTIs.

Evidence synthesis

Results obtained from the literature search showed that adherence to guidelines is not optimal. The survey demonstrated that antibiotics remain one of the treatments of UTIs. However, most of the urologists are aware of the problem caused by the resistance to antibiotics and prefer alternative methods for the prophylaxis of UTIs. Considering the alternative methods, the authors concluded that GAG therapy is highly effective in preventing rUTIs.

Conclusions

Adherence to the international guidelines is important to align the clinical practice and avoid the spreading of antibiotic resistance. The survey outlines that the misuse and overuse of antibiotics are major problems; an analysis of clinical evidence confirms that GAG therapy is a valuable therapeutic approach to prevent the recurrence of episodes of UTIs and to limit the onset of antibiotic resistance.

Patient summary

Although antibiotic therapy is primarily used for the management of urinary tract infections (UTIs), misuse and overuse of antibiotics are of concern. Adherence to the international guidelines is important to prevent the spreading of antibiotic resistance. Clinical evidence confirms that the use of glycosaminoglycans is a valuable therapeutic approach to prevent UTI recurrence and limit the onset of antibiotic resistance.

Management of Recurrent Cystitis in Women: When Prompt Identification of Risk Factors Might Make a Difference

BACKGROUND

Management of recurrent urinary tract infection (rUTI) is still challenging. A better understanding of the natural history of rUTI could help us reduce antibiotic use and improve antibiotic stewardship.

OBJECTIVE

To describe the effect of risk identification, stratification, and counseling on the natural course of the disease in women with rUTI.

DESIGN, SETTING, AND PARTICIPANTS

A total of 373 women affected by recurrent cystitis were enrolled in this longitudinal cohort study between December 2014 and December 2019. A systematic and standardized identification of risk factors was performed.

INTERVENTION

As intervention, risk factors were treated or removed where possible. Patients with nonremovable risk factors were included in the control group. All patients were scheduled for follow-up visits every 6 mo.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The main outcome measures were the rate of symptomatic recurrences and improvement in questionnaire results from baseline to the end of the follow-up period. Reduction of antibiotic usage was regarded as a secondary outcome measure.

RESULTS AND LIMITATIONS

Finally, 353 women were analyzed: 196 in the study group and 157 in the control group. At the end of the follow-up period, a statistically significant reduction in the symptomatic recurrence rate was found between the two groups (0.9 ± 0.2 and 2.6 ± 0.5; p < 0.001), as well as in quality of life and anxiety according to mean questionnaire results: quality of life (0.88 ± 0.06 and 0.63 ± 0.09; p < 0.001) and Spielberger State-Trait Anxiety Inventory-Form Y (32.7 ± 9.3 and 47.5 ± 14.3; p < 0.001). The use of antibiotics was significantly lower in the study group: 4410 versus 9821 (p < 0.001). A limitation to consider is the lack of a randomized design for the active approach in the high-risk group.

CONCLUSIONS

Identification, counseling, and removal of risk factors, where possible, are able to change the natural history of rUTI, by reducing the number of symptomatic episodes and antibiotic use and improving quality of life.

PATIENT SUMMARY

In this report, we analyzed a large cohort of women affected by recurrent urinary tract infections and followed for a long time period. We found that risk factor identification and counseling may change the natural history of recurrent urinary tract infections, concluding that this approach is able to reduce the number of symptomatic episodes, reduce antibiotic usage, and improve patients' quality of life.

Fosfomycin Trometamol for the Prevention of Infectious Complications After Prostate Biopsy: A Consensus Statement by an International Multidisciplinary Group

CONTEXT

Transrectal ultrasound-guided prostate biopsy (TRPB) has been a standard of care for diagnosing prostate cancer but is associated with a high incidence of infectious complications.

OBJECTIVE

To achieve an expert consensus on whether fosfomycin trometamol provides adequate prophylaxis in TRPB and discuss its role as prophylaxis in transperineal prostate biopsy (TPPB).

EVIDENCE ACQUISITION

An international multidisciplinary group of experts convened remotely to discuss how to best use fosfomycin in various clinical settings and patient situations. Six statements related to prostate biopsy and the role of fosfomycin were developed, based on literature searches and relevant clinical experience.

EVIDENCE SYNTHESIS

Consensus was reached for all six statements. The group of experts was unanimous regarding fosfomycin as a preferred candidate for antimicrobial prophylaxis in TRPB. Fosfomycin potentially also meets the requirements for empiric prophylaxis in TPPB, although further clinical studies are needed to confirm or refute its utility in this setting. There is a risk of bias due to sponsorship by a pharmaceutical company.

CONCLUSIONS

Antimicrobial prophylaxis is mandatory in TRPB, and fosfomycin trometamol is an appropriate candidate due to low rates of resistance, a good safety profile, sufficient prostate concentrations, and demonstrated efficacy in reducing the risk of infectious complications following TRPB.

PATIENT SUMMARY

Patients undergoing transrectal ultrasound-guided prostate biopsy (TRPB) have a high risk of infectious complications, and antimicrobial prophylaxis is mandatory. However, increasing antimicrobial resistance, as well as safety concerns with fluoroquinolones, has restricted the number of antimicrobial options. Fosfomycin trometamol meets the requirements for a preferred antimicrobial in the prophylaxis of TRPB.

Detection and Drug Susceptibility Testing of Neisseria gonorrhoeae Using Isothermal Microcalorimetry

Background: Gonorrhea is a frequently encountered sexually transmitted disease that results in urethritis and can further lead to pelvic inflammatory disease, infertility, and possibly disseminated gonococcal infections. Thus, it must be diagnosed promptly and accurately. In addition, drug susceptibility testing should be performed rapidly as well. Unfortunately, Neisseria gonorrhoea is a fastidious microorganism that is difficult to grow and requires culturing in an opaque medium. Methods: Here, we used isothermal microcalorimetry (IMC) to monitor the growth and the antimicrobial susceptibility of N. gonorrhoea. Results: Using IMC, concentrations of N. gonorrhoea between 2000 and 1 CFU·mL⁻¹ were detected within 12 to 33 h. In addition, drug susceptibility could be monitored easily. Conclusions: The use of isothermal microcalorimetry provides an interesting and useful tool to detect and characterize fastidious microbes such as N. gonorrhoea that require media incompatible with optical detection conventionally used in many commercial systems.

Evaluating the differences in the early laparoscopic donor nephrectomy learning curves of a Swiss high volume transplant program and a South African low volume transplant program after knowledge transfer

Background

To describe the retroperitoneoscopic donor nephrectomy learning curve differences between a high volume (training) hospital in Basel, Switzerland, and a low volume (trainee) hospital in Cape Town, South Africa, after knowledge transfer. The South African hospital is resource constraint in hospital and training equipment. Techniques for performing the surgery were near identical.

Methods

Both units maintained prospective databases. Comparisons were made of the first 74 cases in each database: Basel’s series were from 19 January 2001 until 28 June 2004, while the Cape Town Hospital were from 8 April 2008 until 15 July 2008. Four surgeons operated in the Basel group, while only one surgeon operated in the Cape Town group. Variables compared include operating time (first skin incision until kidney was extracted), warm ischaemic time (renal arterial occlusion until cold bench reperfusion), blood loss, graft function, and hospital stay. We also analysed the first and last 25 cases of each series. Subgroup analysis of a single Basel surgeon was conducted.

Results

Donor age (means: Basel vs. Cape Town 54 vs. 33 p < 0.0001) and gender (males vs. females Cape Town 57% male and Basel 31% male) differed widely. The Basel group did more left-sided operations (72% vs. 58%). Operative times, blood loss and donor creatinine did not differ. Warm ischaemic time was significantly shorter in the Basel group (Cape Town mean 204 s Basel mean 130 s P = 0.0023). There was double the number of early graft failures in the South African group (six vs. three)—not related to donor surgery. Both groups showed a decline in operating times, plateauing at 30–34 cases.

Conclusions

There are statistically significant differences in some aspects of the learning curves of the Swiss (training) and South African (trainee) hospitals. These differences are clinically not pronounced, and the knowledge transfer was worth the effort.

[Prostate biopsy 2021: current management]

Infectious complications following prostate biopsy are on the rise due to an increase in antimicrobial resistance, mainly against fluoroquinolones. The use of fluoroquinolones for perioperative prophylaxis is no longer approved by the national authorities in Germany. The EAU guideline group on urological infections has recently published a meta-analysis in two parts based on randomised controlled trials (RCTs). Transperineal prostate biopsy is associated with a significantly reduced rate of infectious complications compared with transrectal biopsy and should therefore be preferred. If transrectal biopsy is performed, intrarectal cleaning with povidone-iodine and antibiotic prophylaxis without fluoroquinolones should be chosen. Antibiotic prophylactic strategies include targeted prophylaxis after susceptibility testing of the rectal flora, augmented prophylaxis with multiple antibiotics and empiric mono-prophylaxis with non-fluoroquinolones. Data from RCTs are available for aminoglycosides, third-generation cephalosporins and fosfomycin trometamol.

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.

A Review of Methods to Determine Viability, Vitality, and Metabolic Rates in Microbiology

Viability and metabolic assays are commonly used as proxies to assess the overall metabolism of microorganisms. The variety of these assays combined with little information provided by some assay kits or online protocols often leads to mistakes or poor interpretation of the results. In addition, the use of some of these assays is restricted to simple systems (mostly pure cultures), and care must be taken in their application to environmental samples. In this review, the necessary data are compiled to understand the reactions or measurements performed in many of the assays commonly used in various aspects of microbiology. Also, their relationships to each other, as metabolism links many of these assays, resulting in correlations between measured values and parameters, are discussed. Finally, the limitations of these assays are discussed.

European Association of Urology Position Paper on the Prevention of Infectious Complications Following Prostate Biopsy

The transperineal approach is preferred to reduce prostate biopsy (PB)-related infections. Fluoroquinolones are suspended for prophylaxis of PB in the European Union; therefore, alternative antibiotics based on local resistance, or targeted prophylaxis, in conjunction with povidone-iodine rectal preparation are recommended for transrectal PB.

[Infectious complications following prostate biopsy-Major changes 2020]

BACKGROUND

Infectious complications following prostate biopsy are increasing and fluoroquinolone prophylaxis has recently been suspended in Germany by the national authorities.

OBJECTIVES

This review is intended to highlight current strategies for reducing infectious complications following prostate biopsy.

MATERIALS AND METHODS

The European Association of Urology (EAU) guideline group on urological infections recently published a meta-analysis in two parts based on randomized controlled trials (RCTs). The most important contents shall be presented here.

RESULTS

Transperineal prostate biopsy is associated with significantly reduced infectious complications than transrectal biopsy. If transrectal biopsy is performed, intrarectal cleaning with povidone-iodine and antibiotic prophylaxis without fluoroquinolones should be chosen. Antibiotic prophylactic strategies include targeted prophylaxis after susceptibility testing of the rectal flora, augmented prophylaxis with multiple antibiotics and empiric monoprophylaxis with nonfluoroquinolones. Here data from RCTs are available for aminoglycosides, third generation cephalosporines, and fosfomycin trometamol.

CONCLUSIONS

The transperineal approach is preferred to reduce prostate biopsy-related infections. Fluoroquinolones are no longer approved for prophylaxis. Thus, alternative antibiotics based on local resistance, or targeted prophylaxis, in conjunction with povidone-iodine rectal preparation are recommended for transrectal prostate biopsy.

The EAU and AUA/CUA/SUFU Guidelines on Recurrent Urinary Tract Infections: What is the Difference?

For diagnosis of urinary tract infection (UTI), low bacterial counts in urine culture need to be considered more often. Non-antibiotic prophylaxis should be prioritized before antibiotic prophylaxis in patients with uncomplicated, recurrent UTI. Immunoprophylaxis in patients with rUTI deserves better consideration.

Guidelines in urology: Lights and shadows

Clinical practice guidelines have become increasingly important in the decision-making process in many clinical conditions and have been recognized as key instruments to improve the quality of care. On the one hand, guidelines represent a good tool for improving patient's outcome, and on the other hand, the adherence to guidelines and good practice recommendations is mandatory to reduce the risk of legal disputes. A recent revision by the Italian Parliament of the legal system that rules the responsibilities of health professionals and health care safety stimulated all clinicians to improve their adhesion to clinical guidelines. It is justified by the high-quality level obtained in the recent years by the international guidelines. In the recent years, a revision of the clinical guideline development has been done. In particular, the European Association of Urology Guideline Office changed the "Guidelines for Guidelines," and a rigorous development process has been established. A clinical recommendation is produced after a rigorous methodological process using an analysis of all published clinical trials, and the expert opinion is not yet considered. For oncological guidelines, the adherence to the producing process is easily feasible due to the high number of clinical trials; for non-oncological guidelines, instead, the small number of clinical trials could represent a problem for obtaining recommendation based on rigorous methodology. Here, on the basis of these considerations, we aim to discuss the lights and the shadows of the clinical applicability of guidelines in urology.

European Association of Urology Guidelines Office Rapid Reaction Group: An Organisation-wide Collaborative Effort to Adapt the European Association of Urology Guidelines Recommendations to the Coronavirus Disease 2019 Era

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.

Comparison of isothermal microcalorimetry and BACTEC MGIT960 for the detection of the metabolic activity of Mycobacterium tuberculosis in sputum samples

INTRODUCTION

This study explores the uses of microcalorimetry to detect Mycobacterium tuberculosis (TB) in sputum. Microcalorimetry measures metabolic heat evolution during cellular proliferation of tuberculosis (TB) and is considered as a possible alternative to conventional diagnostic tools.

OBJECTIVES

To compare the time to detection (TTD) from the BACTEC™ MGIT™ 960 and the calScreener™ calorimetric system.

METHODS

Sixty-four sputa samples were selected from patients with confirmed pulmonary tuberculosis. Those sample were then decontaminated and analysed using calorimetry and BACTEC MGIT 960 system.

RESULTS

The incubation period until detection of M. tuberculosis in the sample was 8·5 ± 3·7 days for the MGIT system and 10·1 ± 4·1 days (mean ± SD) for calorimetry.

CONCLUSIONS

The microincubations in the 48-well format calScreener offers potential for rapid and accurate diagnostic of TB in different samples. Although TTD from calorimetry is still longer than with the MGIT, our findings suggest that several improvements are possible. Still, the instrument is ideal for continuous, real-time analysis of net metabolic heat release of limited sample numbers.

SIGNIFICANCE AND IMPACT OF THE STUDY

Our result emphasizes that with further optimization, calorimetry can become an alternative detection method for tuberculosis.

UTI − quo vadis? New alternatives to treat uncomplicated urinary tract infections

Urinary tract infections (UTI) are one of the most common problems in urology clinics. The European Association of Urology (EAU) has been pioneering in its efforts to disseminate the latest clinical findings through the organization of the annual EAU congresses. At this year’s congress (EAU Barcelona 2019), various satellite symposia were organized, focusing on specific issues in the field of urology. "UTI − quo vadis? New alternatives to treat uncomplicated urinary tract infections" was one of the industry-sponsored symposia, organized with the aim of evaluating the current scenario and also throwing light on the paradigm shift in the treatment of acute, uncomplicated lower urinary tract infections (uUTI). Several interlinking topics were presented during this symposium. The topics covered antibiotic resistance, involving a presentation of the current data from the Global Prevalence Study on Infections in Urology (GPIU-study). This discussion was followed by case reports on the impact of antibiotic resistance on the management of patients with UTI/uUTI and treatment options for UTI/uUTI according to current guidelines. The highlight of the symposium was the presentation of very recent data from a gold standard phase III clinical trial (double-blind, double-dummy randomized study), demonstrating the non-inferiority of a herbal medicine (BNO 1045) versus antibiotic therapy (fosfomycin trometamol (FT), as a single dose = 3 g) for the treatment of acute, uncomplicated cystitis.

[Urological infections and migration]

In the context of refugee migrations infectious diseases are being more frequently diagnosed, which the responsible physicians as well as urologists have never seen before. This is due to the poorer health and hygiene conditions in the country of origin, during the flight and in the refugee camps. In Europe increasing incidences of tuberculosis, schistosomiasis and scabies have recently been observed. Tuberculosis and schistosomiasis are often accompanied by unspecific symptoms or can resemble normally encountered urological diseases. Due to the highly contagious nature of scabies, a screening of new arrivals is recommended. A timely differential diagnostic inclusion of these disease patterns is enormously important. Despite the reduction in the numbers of asylum applications in Germany, a higher number of unregistered migrants is generally assumed, who also elude the healthcare system and can therefore contribute to the spread of these rare infectious diseases.

Awareness of European practitioners toward uncommon tropical diseases: are we prepared to deal with mass migration? Results of an international survey

PURPOSE

The recent rise in migration from Africa through the Mediterranean basin into Europe has resulted in an increased incidence of uncommon diseases such as schistosomiasis and genito-urinary tuberculosis, which were previously largely unknown in this region. This study aimed to evaluate the insight of European urologists into diagnosing and managing these disease conditions and to determine whether they were adequately prepared to deal with the changing disease spectrum in their countries.

METHODS

A survey including specific questions about the diagnosis and management of 'tropical' urological diseases was distributed among urologists working in Europe and Africa. Multivariate logistic regression models were performed to detect the continent (African or European) effect on knowledge of and insight into tropical urological diseases.

RESULTS

A total of 312 surveys were administered. African and European respondents accounted for 109 (36.09%) and 193 (63.91%) respondents, respectively. The multivariate logistic regression analysis demonstrated a significant deficiency in the knowledge of tropical urological diseases in the European cohort compared with the African cohort (p < 0.05). Moreover, in the European cohort, markedly superior knowledge of tropical urological diseases was observed for respondents who had previously worked in a developing country.

CONCLUSIONS

Though European urologists are not required to have the same insight as African urologists, they showed a very unsatisfactory knowledge of tropical urological diseases. The experience of working in a developing country could improve the knowledge of European urologists regarding tropical urological diseases.

[Syphilis and Henry VIII : A disease writes world history]

Syphilis is a chronic sexually transmitted disease (STD). At the end of the 15th century, Christopher Columbus imported it as "a souvenir" from his first voyage of discovery. The disease met a weakened and not yet infected population. The disease quickly engulfed all of Europe. The course of the disease was much more dramatic than it is today. Even royal houses were not spared. Using the example of Henry VIII of England this article briefly outlines the influence of syphilis both to the house of Tudor and thus on the big political stage.

The use of oral fosfomycin-trometamol in patients with catheter-associated urinary tract infections (CAUTI): new indications for an old antibiotic?

We present the results of a multicenter retrospective study of 35 difficult-to-treat patients with urinary tract infections associated with indwelling urinary catheters (CAUTIs). All patients received oral administration of 3 g fosfomycin trometamol once a day for two days and then with a dose of 3 g every 48 h for two weeks. The most commonly isolated strains were: Escherichia coli (65.7%) and Enterococcus spp. (25.7%); prevalence of Extended-Spectrum Beta-Lactamase strains was 48.5%. Six patients (17.1%) had a clinical response after a single dose of fosfomycin trometamol, 12 (34.2%) after two doses and 13 (37.1%) patients had a clinical response after three or more doses. Four patients (11.6%) failed prolonged antibiotic treatment with fosfomycin trometamol. During the follow-up period, 30 out of 35 (85.7%) patients were without symptomatic infections. No significant side effects were reported. In conclusion, fosfomycin trometamol seems to be a valid treatment option in patients with CAUTIs.

Infectious Complications After Laser Vaporization of Urinary Stones During Retrograde Intrarenal Surgery Are Not Associated with Spreading of Bacteria into Irrigation Fluid but with Previous Use of Fluoroquinolones

BACKGROUND

The pathogenesis of infectious complications after retrograde intrarenal surgery (RIRS) is not fully understood.

OBJECTIVE

To evaluate spreading of bacteria into irrigation fluid and blood during RIRS for stone management and to correlate such spreading with infectious complications.

DESIGN, SETTING, AND PARTICIPANTS

From January to December 2017, 38 patients who underwent RIRS for stones in two urological units were enrolled in this prospective, longitudinal cohort study.

INTERVENTION

A urine culture was taken before surgery and antimicrobial prophylaxis was given in line with the European Association of Urology guidelines. Blood and irrigation fluid samples were collected at the start of the endoscopic procedure and every 30min during the procedure. All samples were microbiologically examined and findings were compared with clinical data.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSES

Symptomatic and asymptomatic urinary tract infectious complications were correlated with microbiological and clinical data, using Student t test or Mann-Whitney U test.

RESULTS AND LIMITATIONS

Ten patients showed significant bacterial growth in irrigation fluid samples (seven Escherichia coli, two Klebsiella pneumoniae, and one Pseudomonas aeruginosa). Eight patients (21%) got febrile urinary tract infections during hospital stay: two had bacterial growth in the irrigation fluid (25%) and one also had bacteremia (12.5%). No correlation was found either between the bacterial growth in the irrigation fluid samples and the urine cultures that were taken before the procedure, or between the bacterial growth in the irrigation fluid samples and the development of postoperative infectious complications. Previous use of fluoroquinolones and a history of urinary tract infections were associated with infectious complications after RIRS.

CONCLUSIONS

We demonstrated spreading of bacteria into the irrigation fluid during RIRS procedures, but this spreading was not associated with the development of infectious complications. Particular attention should be given to previous antibiotic treatment before administration of antimicrobial prophylaxis.

PATIENT SUMMARY

Bacterial spreading into irrigation fluid is a common finding during retrograde intrarenal surgery, but it is not associated with infectious complications after the procedure. Particular attention should be given to previous antibiotic treatment before administration of antimicrobial prophylaxis.

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.

Update on Strategies to Reduce Infectious Complications After Prostate Biopsy

CONTEXT

Prostate biopsy is one of the most performed procedures in urology. As a diagnostic procedure it should be of low risk. However, morbidity following prostate biopsy is common due to infectious complications.

OBJECTIVE

To describe how to reduce infectious complications following prostate biopsy. We report on antibiotic and technical interventions to reduce infectious complications.

EVIDENCE ACQUISITION

The data presented are based on a narrative review. Search in PubMed and Medline was performed until May 2018 with a focus on randomised controlled trials and meta-analyses. Articles were reviewed for data on symptomatic infections, hospitalisation, and adverse events.

EVIDENCE SYNTHESIS

Antibiotic prophylaxis is the standard of care. However, the duration of antibiotic preemptive treatment is still under debate. The use of augmented antibiotic prophylaxis as well as targeted antibiotic prophylaxis might be of potential value, but evidence is currently limited. Moreover, no antibiotic class was shown to be clearly superior to another. The evaluation of the technical aspects during prostate biopsy reveals that rectal preparation with povidone-iodine is clearly effective to reduce infectious complications. Transperineal biopsy has a potential benefit to reduce infectious complications, but powerful randomised controlled studies are missing. Finally, the number of biopsy cores, the application of periprostatic nerve block, or the use of a cleansing enema has no impact on prostate biopsy in terms of infectious complications.

CONCLUSIONS

The available data only suggest that rectal preparation with povidone-iodine as well as antibiotic prophylaxis is of significant advantage to reduce infectious complications following prostate biopsy. The augmented and targeted antibiotic prophylaxis shows some potential, but need further validation.

PATIENT SUMMARY

In this review we evaluate the best management strategy to prevent infectious complications following prostate biopsy. We show that antibiotic prophylaxis is essential for prostate biopsy and that rectal preparation with povidone-iodine is mandatory.

Basic patient characteristics predict antimicrobial resistance in E. coli from urinary tract specimens: a retrospective cohort analysis of 5246 urine samples

BACKGROUND

Antimicrobial resistance data from surveillance networks are frequently do not accurately predict resistance patterns of urinary tract infections at the bedside.

OJECTIVE

To determine simple patient- and institution-related risk factors affecting antimicrobial resistance patterns of Escherichia coli urine isolates.

METHODS

From January 2012 to May 2015 all consecutive urine samples with significant growth of E. coli (≥103 CFU/ml) obtained from a tertiary care hospital were analysed for antimicrobial susceptibility and related to basic clinical data such a patient age, ward, sample type (catheter vs non-catheter urine).

RESULTS

Antimicrobial susceptibility testing was available for 5246 E. coli urine isolates from 4870 patients. E. coli was most commonly resistant to amoxicillin (43.1%), cotrimoxazole (24.5%) and ciprofloxacin (17.4%). Resistance rates were low for meropenem (0.0%), fosfomycin (0.9%) and nitrofurantoin (1.5%). Significantly higher rates of resistance to ciprofloxacin (32.8 vs 15.8%) and cotrimoxazole (30.6 vs 23.9%) were found in urological patients compared with patients on other wards (p <0.01). In multivariable analysis, predictors for E. coli resistance against ciprofloxacin and cotrimoxazole were: treatment in the urological unit (odds ratio [OR] 2.04, 95% confidence interval [CI] 1.63-2.54; p <0.001 and OR 1.33, 95% CI 1.07-1.64; p = 0.010, respectively), male sex (OR 1.93, 95% CI 1.630-2.29; p <0.001 and OR 1.22, 95% CI 1.22-1.04; p = 0.015), and only to a lesser extent urine samples obtained from indwelling catheters (OR 1.30, 95% CI 1.05-1.61; p = 0.014 and OR 1.26, 95% CI 1.04-1.53; p = 0.020). Age ≥65 years was associated with higher resistance to ciprofloxacin (OR 1.42, 95% CI 1.21-1.67; p <0.001), but lower resistance to cotrimoxazole (OR 0.76, 95% CI 0.67-0.86; p <0.001).

CONCLUSIONS

Simple bedside patient data such as age, sex and treating hospital unit help to predict antimicrobial resistance and can improve the empirical treatment of urinary tract infections.

Management of Urethritis: Is It Still the Time for Empirical Antibiotic Treatments?

CONTEXT

Urethritis prevalence in Europe changed in the last years due to both the increase of migratory streams from North Africa and the more frequent exposition of males to relevant risk factors. Owing to these reasons, urethritis treatment should be optimized by accurate microbiological investigations to avoid the risk of persistence, recurrence, or reinfection.

OBJECTIVE

The aim of this systematic review is to optimize the treatments for urethritis and investigate the applicability of nucleic acid amplification test (NAAT) as the primary microbiological investigation.

EVIDENCE ACQUISITION

A literature search in Medline, Cochrane, and Google Scholar databases was conducted up to June 2018. Subject headings were selected as follows: Urethritis OR gonococcal urethritis OR non-gonococcal urethritis AND Antibiotics OR Recurrence. A total of 528 abstracts were identified and selected. Finally, 12 full-text articles were selected for a qualitative synthesis. The Preferred Reported Items for Systematic Reviews and Meta-Analyses statement was used to perform an accurate research checklist and report.

EVIDENCE SYNTHESIS

Empirical treatments are no more recommended, although a broad spectrum of antibiotic therapy may be initiated while awaiting the results from pathogens' microbiological characterization. First-line treatment for gonococcal urethritis consists of a single dose of ceftriaxone/azithromycin combined therapy. Specific therapies should be initiated for nongonococcal urethritis according to each single pathogen involved in the infection process. Owing to this reason, NAAT is mandatory in the clinical approach to the disease, although the Gram stain of urethral discharge or smear remains applicable for some less frequent nongonococcal urethritis. Moreover, the urethritis "modern view" also includes noninfectious etiologies that occurred after traumas or injection of irritating compounds. Sexual abstinence of at least 7 d should be observed from the start of treatment to avoid reinfection, while sexual partners should evenly be treated.

CONCLUSIONS

The treatment of urethritis implies accurate determination of pathogens involved in the infection process by NAAT with subsequent appropriate antibiotic therapy, thus avoiding the risk of antibiotic resistance and overuse of antibiotics indicated for empirical treatments. The population exposed to relevant risk factors should be adequately informed about the increased risk of developing infections and motivated toward the intensive use of condoms during sexual intercourses.

PATIENT SUMMARY

Urethritis is a sexually transmitted disease generally characterized by urethral discharge or other symptoms such as itching, tingling, and apparent difficulties in having a regular urinary flow. Microbiological investigations are mandatory to obtain satisfactory results from the treatment. Multiple antibiotic treatments are often necessary due to the high risk of multiple pathogens responsible for the disease. Similarly, sexual partners should be investigated and treated in the same way. Several risk factors such as immunodeficiency, multiple sexual partners, homo- and bisexuality, and alcohol abuse may be related to the disease. In these cases, the use of condom is strongly recommended.

Non-molecular Methods to Detect Bacteriuria Prior to Urological Interventions: A Diagnostic Accuracy Systematic Review

Urine culture still has to be considered as the gold standard to rule out bacteriuria and should, therefore, be obtained prior to invasive endoscopic or open urological procedures to minimize the risk of severe infectious complications.

[New microbiological techniques]

Microbiological diagnostic procedures have changed rapidly in recent years. This is especially true in the field of molecular diagnostics. Classical culture-based techniques are still the gold standard in many areas; however, they are already complemented by automated and also molecular techniques to guarantee faster and better quality results. The most commonly used techniques include real-time polymerase chain reaction (RT-PCR) based systems and nucleic acid hybridization. These procedures are used most powerfully from direct patient samples or in assays to detect the presence of nonculturable or fastidious organisms. Further techniques such as DNA sequencing are not yet used routinely for urological samples and can be considered experimental. However, in conjunction with dropping prices and further technical developments, these techniques promise to be used much more in the near future. Regarding bacterial identification from culture, mass spectrometry (MALDI-TOF MS) has become the technique of choice in recent years especially in Europe. It has tremendously shortened the time to result. This is now going to be extended to antibiotic susceptibility testing. This is of paramount importance in view of ever rising antimicrobial resistance rates. Techniques described in this review offer a faster and better microbiological diagnosis. Such continuous improvements are critical especially in times of cost pressure and rising antimicrobial resistance rates. It is in our interest to provide the best possible care for patients and in this regard a good and effective communication between the laboratory and the clinician is of vital importance.

Metabolic activity of mature biofilms of Mycobacterium tuberculosis and other non-tuberculous mycobacteria

Mycobacteria are classified into two groups, fast- and slow-growing. Often, fast-growing mycobacteria are assumed to have a higher metabolic activity than their slower counterparts, but in mature biofilms this assumption might not be correct. Indeed, when measuring the metabolic activity of mycobacterial biofilms with two independent non-invasive techniques (isothermal microcalorimetry and tunable diode laser absorption spectrometry), mature biofilms of slow- and fast-growing species appeared more alike than expected. Metabolic heat production rate was 2298 ± 181 µW for M. smegmatis and 792 ± 81 µW for M. phlei, while M. tuberculosis and M. bovis metabolic heat production rates were between these values. These small differences were further confirmed by similar oxygen consumption rates (3.3 ± 0.2 nMole/s and 1.7 ± 0.3 nMole/s for M. smegmatis and M. tuberculosis, respectively). These data suggest that the metabolic potential of slow-growing mycobacterial biofilms has been underestimated, particularly for pathogenic species.

An alternative sterility assessment for parenteral drug products using isothermal microcalorimetry

AIMS

Production and release of injectable drug solutions are highly regulated since the administration of injectables bypasses natural body barriers. The sterility test is the last opportunity of product quality assessment. However, sterility is currently assessed by visual inspection (VI) that is time consuming and somewhat subjective. Therefore, we assessed isothermal microcalorimetry (IMC) as a replacement for the VI of the filtration based state-of-the-art sterility control.

METHODS AND RESULTS

We used ATCC strains and house isolates to artificially contaminate frequently produced monoclonal antibodies (Avastin, Mabthera, Herceptin). After filtration, growth was assessed with IMC. Growth of all micro-organisms was reliably and reproducibly detected 4 days after inoculation, which was significantly faster than with VI.

CONCLUSIONS

The reliability and the sensitivity of IMC have a large potential to improve sterility controls. Further evaluation of this alternative method is therefore highly recommended.

SIGNIFICANCE AND IMPACT OF THE STUDY

Drug safety is of great concern for public health. Faster and safer drug production could be achieved using the technique described here. All the tests were performed with real manufactured drugs and complied with pharmaceutical standards. This suggests that drug sterility testing can be improved with potentially increased safety and cost reduction.

The role of nutraceuticals and phytotherapy in the management of urinary tract infections: What we need to know?

Urinary Tract Infections (UTIs) are amongst the most common infectious diseases and carry a significant impact on patient quality of life and health care costs. Despite that, there is no well-established recommendation for a "standard" prophylactic antibiotic management to prevent UTI recurrences. The majority of patients undergoes long-term antibiotic treatment that severely impairs the normal microbiota and increases the risk of development of multidrugresistant microorganisms. In this scenario, the use of phytotherapy to both alleviate symptoms related to UTI and decrease the rate of symptomatic recurrences is an attractive alternative. Several recently published papers report conflicting findings and cannot give confident recommendations for the everyday clinical practice. A new approach to the management of patients with recurrent UTI might be to use nutraceuticals or phytotherapy after an accurate assessment of the patient`s risk factors. No single compound or mixture has been identified so far as the best preventive approach in patients with recurrent UTI. We reviewed our non-antibiotic approach to the management of recurrent UTI patients in order to clarify the evidence-base for the commonly used substances, understand their pharmacokinetics and pharmacodynamics in order to tailor the best way to improve patient's quality of life and reduce the rate of antibiotic resistance. Lack of a gold-standard recommendation and the risk of increasing antibiotic resistance is the reason why we need alternatives to antibiotics in the management of urinary tract infections (UTIs). A tailored approach according to bacterial characteristics and the patient risk factors profile is a promising option.

Is Preoperative Assessment and Treatment of Asymptomatic Bacteriuria Necessary for Reducing the Risk of Postoperative Symptomatic Urinary Tract Infections After Urologic Surgical Procedures?

OBJECTIVE

To evaluate whether it is always necessary to test for the presence of asymptomatic bacteriuria (AB) in patients undergoing urologic surgical procedures, and if present, whether to treat AB with antimicrobial prophylaxis.

MATERIALS AND METHODS

All patients who underwent urologic surgical procedures from December 2008 to October 2013 in a tertiary referral urologic center were considered for this study. All patients received antimicrobial prophylaxis in line with European Association of Urology guidelines on urologic infections. AB was diagnosed if ≥10⁵ colony-forming units/mL were cultured. The population was subdivided into 2 groups: group A, patients with preoperative AB, and group B, patients without AB. Data on postoperative symptomatic urinary tract infections (UTIs) were compared for the 2 groups.

RESULTS

A total of 2201 patients were considered eligible for this study and were analyzed; 668 (30.4%) patients were found to harbor AB (group A), and 1533 (69.6%) patients did not have AB (group B). Microbiologically verified symptomatic postoperative UTIs occurred in 198 patients (8.9%). No difference in terms of overall rate of postoperative symptomatic UTI was found between the 2 groups (group A: 70 [10.4%] and group B: 128 [8.3%]; OR: 1.28 95%CI 0.94-1.74; P = .12), as well as in terms of urosepsis (group A: 2 [0.30%] and group B: 4 [0.26%]; P = 1.0).

CONCLUSION

In patients undergoing urologic surgical procedures who are receiving antimicrobial prophylaxis in accordance with European Association of Urology guidelines, the preoperative presence of AB in this study was not associated with a higher incidence of postoperative symptomatic UTI.

Growth Patterns of Clostridium difficile - Correlations with Strains, Binary Toxin and Disease Severity: A Prospective Cohort Study

A broad spectrum of symptoms has been associated with C. difficile infection (CDI). Several studies indicate that toxin-production correlates with growth rates of C. difficile. This study aimed to correlate growth rates of C. difficile with disease severity and strain characteristics. From 01/2003 to 10/2011, strains from a prospective cohort of all inpatients with CDI at the University Hospital Basel, Switzerland were analyzed regarding binary toxin, presence of the tcdC deletion and ribotype. Isothermal microcalorimetry was performed to determine growth rates, quantified by the Gompertz function. Ordered logistic regression models were used to correlate disease severity with strain features and clinical characteristics. Among 199 patients, 31 (16%) were infected with binary toxin-producing strains, of which the tcdC gene-deletion nt117 was detected in 9 (4%). Disease severity was classified as mild in 130 patients (65.3%), as severe in 59 patients (29.7%) and as severe/complicated in 10 patients (5.0%). Growth rates were inversely associated with disease severity in univariable (OR 0.514, 95%CI 0.29–0.91, p = 0.023) and multivariable analyses (OR 0.51, 95%CI 0.26–0.97, p = 0.040). While none of the strain characteristics such as presence of the tcdC gene deletion or binary toxin predicted CDI severity, growth rates were inversely correlated with disease severity. Further investigations are needed to analyze growth-regulators and respective correlations with the level of toxin production in C. difficile, which may be important determinants of disease severity.

[Urinary Tract Infections--Current Innovations in Urine Diagnostics]

Urine culture (UC) confirms the diagnosis of urinary tract infection (UTI) and is still considered the diagnostic 'gold standard' for pathogen identification, quantification and resistance testing. However, up to 80% of samples will not yield bacterial growth. Different techniques are currently approved for resistance testing. However, all of them are culture based and have the disadvantage of being very slow. In the field of urology, the development of drug resistance of uropathogens complicates the optimal administration of antimicrobial agents not only in the treatment, but also in the prevention of UTI before endourological and open surgical procedures. In this context, rapid identification of microbiological agents, including timely antimicrobial resistance testing (ART) is desirable. This overview presents alternative techniques (flow cytometry, PCR-based techniques, MALDI-TOF MS and microcalorimetry) to urine culture and discusses their advantages and disadvantages.

How to Use Antimicrobial Prophylaxis in Urological Procedures

A revision of clinical practice in terms of antimicrobial prophylaxis is urgently needed starting from: (1) obtaining information about local pathogen profiles and antimicrobial resistance, (2) evaluating all patient-related risk factors for the development of infectious complications, (3) and prescribing antimicrobials according to the principles of the European Association of Urology guidelines.
