RESUMEN
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.

PURPOSE: To provide a descriptive report of mortality and morbidity in the first 30 days of diagnosis of urosepsis. Secondary aim is to identify risk factors of unfavourable outcomes. METHODS: Prospective observational multicentre cohort study conducted from September 2014 to November 2018 in European hospitals. Adult patients (≥ 18 years) diagnosed with acute urosepsis according to Sepsis-2 criteria with confirmed microbiological infection were included. Outcomes were classified in one of four health states: death, multiple organ failure, single organ failure, and recovery at day 30 from onset of urosepsis. Descriptive statistics and ordinal logistic regression analysis was performed. RESULTS: Three hundred and fifty four patients were recruited, and 30-day mortality rate was 2.8%, rising to 4.6% for severe sepsis. All patients who died had a SOFA score of ≥ 2 at diagnosis. Upon initial diagnosis, 79% (n = 281) of patients presented with OF. Within 30 days, an additional 5% developed OF, resulting in a total of 84% affected. Charlson score (OR 1.14 CI 1.01-1.28), patients with respiratory failure at baseline (OR 2.35, CI 1.32-4.21), ICU admission within the past 12 months (OR 2.05, CI 1.00-4.19), obstruction causative of urosepsis (OR 1.76, CI 1.02-3.05), urosepsis with multi-drug-resistant(MDR) pathogens (OR 2.01, CI 1.15-3.53), and SOFA baseline score ≥ 2 (OR 2.74, CI 1.49-5.07) are significantly associated with day 30 outcomes (OF and death). CONCLUSIONS: Impact of comorbidities and MDR pathogens on outcomes highlights the existence of a distinct group of patients who are prone to mortality and morbidity. These findings underscore the need for the development of pragmatic classifications to better assess the severity of UTIs and guide management strategies. STUDY REGISTRATION: Clinicaltrials.gov registration number NCT02380170.

(1) Background: Urinary tract infections (UTIs) are among the most frequent complications in kidney transplant (KT) recipients. Asymptomatic bacteriuria (ASB) may be a risk factor for UTIs and graft rejection. We aimed to evaluate available evidence regarding the benefit of screening and treatment of ASB within the first year after KT. (2) Evidence acquisition: A systematic literature search was conducted in MEDLINE, the Cochrane Library CENTRAL and Embase. Inclusion criteria were manuscripts in English addressing the management of ASB after KT. The PICO questions concerned Patients (adults receiving a KT), Intervention (screening, diagnosis and treatment of ASB), Control (screening and no antibiotic treatment) and Outcome (UTIs, sepsis, kidney failure and death). (3) Evidence synthesis: The systematic review identified 151 studies, and 16 full-text articles were evaluated. Seven were excluded because they did not evaluate the effect of treatment of ASB. There was no evidence for a higher incidence of lower UTIs, acute pyelonephritis, graft loss, or mortality in patients not treated with antibiotics for ASB. Analysis of comparative non-randomized and observational studies did not provide supplementary evidence to guide clinical recommendations. We believe this lack of evidence is due to confounding risk factors that are not being considered in the stratification of study patients.
RESUMEN
The absence of a consensus-based reference standard for urinary tract infection (UTI) research adversely affects the internal and external validity of diagnostic and therapeutic studies. This omission hinders the accumulation of evidence for a disease that imposes a substantial burden on patients and society, particularly in an era of increasing antimicrobial resistance. We did a three-round Delphi study involving an international, multidisciplinary panel of UTI experts (n=46) and achieved a high degree of consensus (94%) on the final reference standard. New-onset dysuria, urinary frequency, and urinary urgency were considered major symptoms, and non-specific symptoms in older patients were not deemed indicative of UTI. The reference standard distinguishes between UTI with and without systemic involvement, abandoning the term complicated UTI. Moreover, different levels of pyuria were incorporated in the reference standard, encouraging quantification of pyuria in studies done in all health-care settings. The traditional bacteriuria threshold (105 colony-forming units per mL) was lowered to 104 colony-forming units per mL. This new reference standard can be used for UTI research across many patient populations and has the potential to increase homogeneity between studies.

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.

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.
RESUMEN
Defining urinary tract infection (UTI) is complex, as numerous clinical and diagnostic parameters are involved. In this systematic review, we aimed to gain insight into how UTI is defined across current studies. We included 47 studies, published between January 2019 and May 2022, investigating therapeutic or prophylactic interventions in adult patients with UTI. Signs and symptoms, pyuria, and a positive urine culture were required in 85%, 28%, and 55% of study definitions, respectively. Five studies (11%) required all 3 categories for the diagnosis of UTI. Thresholds for significant bacteriuria varied from 103 to 105 colony-forming units/mL. None of the 12 studies including acute cystitis and 2 of 12 (17%) defining acute pyelonephritis used identical definitions. Complicated UTI was defined by both host factors and systemic involvement in 9 of 14 (64%) studies. In conclusion, UTI definitions are heterogeneous across recent studies, highlighting the need for a consensus-based, research reference standard for UTI.
RESUMEN
INTRODUCTION: Patients with neurogenic lower urinary tract dysfunction (NLUTD) reliant on intermittent self-catheterization for bladder emptying are at an increased risk of recurrent urinary tract infections (rUTI). So far, the most common practice in the prevention of rUTIs is long-term low-dose antibiotic prophylaxis, phytotherapy, and immunomodulation, whereby antibiotic prophylaxis inevitably leads to the emergence of drug-resistant pathogens and difficulty in treating infections. Therefore, non-antibiotic alternatives in the prevention of rUTIs are urgently required. We aim to identify the comparative clinical effectiveness of a non-antibiotic prophylaxis regimen in the prevention of recurrent urinary tract infections in patients with neurogenic bladder dysfunction who practice intermittent self-catheterization. METHODS AND ANALYSIS: In this multi-centre, prospective longitudinal multi-arm observational study, a total of 785 patients practising intermittent self-catheterisation due to NLUTD will be included. After inclusion, non-antibiotic prophylaxis regimens will be instilled with either UroVaxom® (OM-89) standard regimen, StroVac® (bacterial lysate vaccine) standard regimen, Angocin®, D-mannose (oral dose 2 g), bladder irrigation with saline (once per day). The management protocols will be pre-defined, but the selection of the protocol will be at the clinicians' discretion. Patients will be followed for 12 months from the onset of the prophylaxis protocol. The primary outcome is to identify the incidence of breakthrough infections. The secondary outcomes are adverse events associated with the prophylaxis regimens and the severity of breakthrough infections. Other outcomes include the exploration of change in susceptibility pattern via the optional rectal and perineal swab, as well as health-related quality of life over time (HRQoL), which will be measured in a random subgroup of 30 patients. ETHICS AND DISSEMINATION: Ethical approval for this study has been granted by the ethical review board of the University Medical Centre Rostock (A 2021-0238 from 28 October 2021). The results will be published in a peer-reviewed journal and presented at relevant meetings. STUDY REGISTRATION NUMBER: German Clinical Trials Register: Number DRKS00029142.
RESUMEN
BACKGROUND: Fournier's gangrene (FG) is a life-threatening, necrotizing infection. Due to the rareness of the disease, it is challenging to plan robust prospective studies. This study aims to describe current practice patterns of FG in Europe and identify implications for planning a prospective FG registry. METHODS: Online non-validated 17-items survey among urologists treating FG in in European hospitals. Questionnaires were analyzed with LimeSurvey (LimeSurvey GmbH Hamburg, Germany). RESULTS: 229 responses from ten different European countries were submitted, and 117 (51.1%) urologists completed the questionnaire. The departments treat a mean of 4.2 (SD 3.11) patients per year. The urology department mostly takes the lead in treating FG patients (n = 113; 96.6%). The practice in FG is very heterogenic and mostly case-based all over Europe, e.g., vacuum-assisted wound closure (VAC) is mostly used (n = 50; 42.7%) as adjunct wound. The biggest challenges in FG are the short time to diagnosis and treatment, standardization and establishment of guidelines, and disease awareness. Additionally, participants stated that an international registry is an outstanding initiative, and predictive models are needed. CONCLUSIONS: There is no standard of care in the diagnosis, treatment, and long-term care of FG all over Europe. Further research could be conducted with a prospective registry.
RESUMEN
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.

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.

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.

PURPOSE: We identify which nonantibiotic strategies could reduce the risk of infectious complications following prostate biopsy. MATERIALS AND METHODS: We performed a literature search on MEDLINE®, Embase® and the Cochrane Database for randomized controlled trials (inception to May 2020) assessing nonantibiotic interventions in prostate biopsy. Primary outcome was pooled infectious complications (fever, sepsis and symptomatic urinary tract infection) and secondary outcome was hospitalization. Cochrane risk of bias tool and GRADE approach were used to assess the bias and the certainty of evidence. The study protocol was registered with PROSPERO (CRD42015026354). RESULTS: A total of 90 randomized controlled trials (16,941 participants) were included in the analysis, with 83 trials being categorized into one of 10 different interventions. Transperineal biopsy was associated with significantly reduced infectious complications as compared to transrectal biopsy (RR 0.55, 95% CI 0.33-0.92, p=0.02, I2=0%, 1,330 participants, 7 studies). Rectal preparation with povidone-iodine was also shown to reduce infectious complications (RR 0.50, 95% CI 0.38-0.65, p <0.000001, I2=27%, 1,686 participants, 8 studies) as well as hospitalization (RR 0.38, 95% CI 0.21-0.69, p=0.002, I2=0%, 620 participants, 4 studies). We found no difference in infectious complications/hospitalization for 6 other interventions, ie number of biopsy cores, periprostatic nerve block, number of injections for periprostatic nerve block, needle guide type, needle type and rectal preparation with enema. In 2 interventions (needle diameter, rectal preparation with chlorhexidine) meta-analysis was not possible. Finally, 7 studies had unique interventions. The certainty of evidence was rated as low/very low for all interventions. CONCLUSIONS: Transperineal biopsy significantly reduces infectious complications compared to transrectal biopsy and should therefore be preferred. If transrectal biopsy is performed, rectal preparation with povidone-iodine is highly recommended. The other investigated nonantibiotic strategies did not significantly influence infection and hospitalization after 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.

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.

Introduction: Urinary tract infections (UTIs) are one of the most common infections worldwide. Under special circumstances, clinicians must rely on laboratory findings, which might have a weak predicting value, misguiding the practitioners and leading to incorrect diagnosis and overuse of antibiotics. Therefore, there is an urgent need for reliable biomarkers in UTIs. Methods: We performed a literature search for biomarkers used in UTIs from January 1999 until May 2020. We used "urinary tract infection" and "biomarker" as the main key words in the PubMed, Medline and Cochrane databases. After peer review, we excluded the duplicates and identified the suitable articles, from which we collected the data and divided the available biomarkers into 5 groups: i) conventional markers; ii) promising, thoroughly studied biomarkers; iii) promising biomarkers that need further studies; iv) biomarkers of unknown significance; v) controversial, not useful markers. Results: We found 131 articles, mostly from the paediatric population. Neutrophil gelatinase-associated lipocalin (NGAL) and interleukins (IL) have a leading role in diagnosing and differentiating UTIs based on a lot of observational, comparative trials. Heparin Binding Protein (HBP), Lactoferrin (LF), Heat-Shock Protein-70 (HSP-70), Human Defensin-5 (HD-5), Lipopolysaccharide Binding Protein (LBP) and mass spectrometry studies are promising, but confirming data are lacking. The measurable components of the innate immune system and local host cell response could be appropriate biomarkers, but their significance is currently unknown. Conclusions: Conventional biomarkers for UTIs have low specificity. The use of urinary NGAL and interleukins could improve the sensitivity and specificity of laboratory diagnosis of UTIs.
RESUMEN
UTIs are amongst the most frequent bacterial infections. However, the clinical phenotypes of UTI are heterogeneous and range from rather benign, uncomplicated infections to complicated UTIs (cUTIs), pyelonephritis and severe urosepsis. Stratification of patients with UTIs is, therefore, important. Several classification systems exist for the description and classification of UTIs, with the common rationale that cUTIs have a higher risk of recurrence or chronification, progression or severe outcome than uncomplicated UTIs. The pathophysiology and treatment of cUTIs and pyelonephritis are driven more by host factors than by pathogen attributes. cUTIs and pyelonephritis are associated with high antimicrobial resistance rates among causative pathogens. However, antimicrobial resistance rates can differ substantially, depending on the population being studied and whether the data being analysed are from surveillance studies, registry data or interventional studies, in which specific inclusion and exclusion criteria are used for patient selection. For example, antibiotic resistance rates are higher in patients with urosepsis than in those with less severe infections. Thus, treatment outcomes differ substantially among studies, ranging from 50% to almost 100% clearance of infection, depending on the patient population analysed, the UTI entities included and the primary outcome of the study. Pyelonephritis and cUTIs have emerged as infection models for the study of novel antibiotics, including extensive investigation of novel substances active against Gram-negative bacteria.

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.

PURPOSE: Infectious complications following prostate biopsy are increasing and fluoroquinolone prophylaxis has recently been banned by the European Commission. In this systematic review we summarize the evidence for different antibiotic prophylaxis regimens. MATERIALS AND METHODS: We searched MEDLINE®, Embase® and Cochrane Database for randomized controlled trials (inception to October 2019) assessing antimicrobial interventions in prostate biopsy. Primary outcome was infectious complications. Exclusion criteria were simultaneous interfering interventions. GRADE (Grading of Recommendations, Assessment, Development and Evaluations) was used to assess the certainty of evidence. Protocol was registered with PROSPERO (CRD42015026354). RESULTS: Overall 59 randomized controlled trials (14,153 participants) and 7 different antimicrobial interventions were included. Antibiotic prophylaxis reduced infectious complications compared to no prophylaxis (RR 0.56, 95% CI 0.40-0.77, p=0.0005, I2=15%, participants 1,753, studies 11). A short-term prophylaxis (single shot to 3 days) was inferior to a long-term prophylaxis (1 to 7 days) with fluoroquinolone (RR 1.89, 95% CI 1.37-2.61, p=0.0001, I2=0%, participants 3,999, studies 17). Fosfomycin trometamol was an alternative to fluoroquinolone with reduced rates of infectious complications (RR 0.49, 95 CI 0.27-0.87, p=0.02, I2=54%, participants 1,239, studies 3). Empiric prophylaxis was inferior to targeted prophylaxis (RR 1.81, 95% CI 1.28-2.55, p=0.0008, I2=48%, participants 1,511, studies 6). Standard prophylaxis was inferior to augmented prophylaxis (using multiple rather than single agent) using a fixed model (RR 2.10, 95% CI 1.53-2.88, p <0.0001, I2=71%, participants 2,597, studies 9), but not using a random model (p=0.07). No difference was observed in infectious complications based on route or timing of antimicrobial prophylaxis. The certainty of evidence was rated as low/very low. CONCLUSIONS: In countries where fluoroquinolones are allowed as antibiotic prophylaxis, a minimum of a full 1-day administration as well as targeted therapy in case of fluoroquinolone resistance is recommended. In countries with a ban on fluoroquinolones, fosfomycin is a good alternative, as is augmented prophylaxis, although no established standard combination exists to date.
