[Urosepsis: pathophysiology, diagnosis, and management-an update]. / Urosepsis: Pathophysiologie, Diagnose und Management ­ ein Update.

Urinary tract infections vary widely in their clinical spectrum, ranging from uncomplicated cystitis to septic shock. Urosepsis accounts for 9-31% of all cases of septicemia and is often associated with nosocomial infections. A major risk factor for urosepsis is the presence of obstructive uropathy, caused by conditions such as urolithiasis, tumors, or strictures. The severity and course of urosepsis depend on both the virulence of the pathogen and the patient's specific immune response. Prompt therapy, including antimicrobial treatment and eradication of the infection source, along with supportive measures for circulatory and respiratory stabilization, and adjunctive therapies such as hemodialysis and glucocorticoid therapy, is crucial. Due to demographic changes, an increase in cases of urosepsis is expected-thus, it is of utmost importance for urologists to be familiar with targeted diagnostics and effective treatment.

Sex Does Not Affect Survival: A Propensity Score-Matched Comparison in a Homogenous Contemporary Radical Cystectomy Cohort.

OBJECTIVES: To determine whether biological sex affects oncological outcome after extended pelvic lymph node dissection, radical cystectomy, and urinary diversion for muscle-invasive bladder cancer, and to identify risk factors impacting outcome. PATIENTS AND METHODS: We performed a single-center, retrospective observational cohort study with prospective data collection with a propensity score matched population. A total of 1165 consecutive patients from 2000 to 2020, (317 women and 848 men) scheduled for open extended pelvic lymph node dissection, radical cystectomy, and urinary diversion for urothelial bladder cancer were included in the final analysis. Overall Survival (OS), Cancer-Specific-Survival (CSS), and Recurrence-Free-survival (RFS) were assessed with multivariable weighted Cox regression analysis as well as with propensity score matched Cox-Regression. RESULTS: No significant difference was found between sexes regarding OS (HR 1.18, [0.93-1.49], P = .16), CSS (HR 0.87, [0.64-1.18], P = .38), or RFS (HR 0.80, [0.59-1.07], P = .13). These results were confirmed after propensity score matching: female sex was not associated with inferior OS (HR 1.20, [0.91-1.60], P = .19), CSS (HR 1.01, [0.75-1.35], P = .97) or RFS (HR 0.98, [0.75-1.27], P = .86). CONCLUSIONS: We did not find a significant difference in cancer-related outcomes or overall survival after extended pelvic lymph node dissection, open radical cystectomy, and urinary diversion for urothelial cancer between males and females even after adjustment with propensity matching score for multiple factors including oncological parameters, smoking status, and renal function.

Indwelling catheter vs intermittent catheterization: is there a difference in UTI susceptibility?

BACKGROUND: Patients with neurogenic lower urinary tract dysfunction (NLUTD) often rely on some type of catheterization for bladder emptying. Intermittent catheterization (IC) is considered the gold standard and is preferred over continuous catheterization, since it is considered to cause fewer urinary tract infections (UTIs) than indwelling catheterization. The main objective of our study was to describe UTI prevalence (at visit) and incidence (within the last 12 months) and urine culture characteristics between patients using an indwelling catheter versus (vs) those performing IC. METHODS: In this cross-sectional study, we prospectively evaluated from 02/2020 to 01/2021 patients with NLUTD undergoing urine cultures for prophylactic reasons or due to UTI symptoms. At visit, all patients underwent a standardized interview on current UTI symptoms as well as UTI history and antibiotic consumption within the past year. Patients using an indwelling catheter (n = 206) or IC (n = 299) were included in the analysis. The main outcome was between-group differences regarding UTI characteristics. RESULTS: Patients using an indwelling catheter were older (indwelling catheter vs IC: median 66 (Q1-Q3: 55-77) vs 55 (42-67) years of age) and showed a higher Charlson comorbidity index (indwelling catheter vs IC: median 4 (Q1-Q3: 2-6) vs 2 (1-4) (both p < 0·001). A total of 40 patients from both groups were diagnosed with a UTI at visit (indwelling catheters vs IC: 8% (16/206) vs 8% (24/299); p = 0·782), and the number of UTIs within the past 12 months was not significantly different between groups. Overall, Escherichia coli (21%), Enterococcus faecalis (17%), and Klebsiella spp. (12%) were the most frequently detected bacteria. CONCLUSIONS: In this cohort of patients with NLUTD, we did not find relevant differences in UTI frequency between groups. These results suggest that UTI-related concerns should not be given undue emphasis when counseling patients for catheter-related bladder emptying methods.

Negative psychological and physiological effects of social networking site use: The example of Facebook.

Social networking sites (SNS), with Facebook as a prominent example, have become an integral part of our daily lives and more than four billion people worldwide use SNS. However, the (over-)use of SNS also poses both psychological and physiological risks. In the present article, we review the scientific literature on the risk of Facebook (over-)use. Addressing this topic is critical because evidence indicates the development of problematic Facebook use ("Facebook addiction") due to excessive and uncontrolled use behavior with various psychological and physiological effects. We conducted a review to examine the scope, range, and nature of prior empirical research on the negative psychological and physiological effects of Facebook use. Our literature search process revealed a total of 232 papers showing that Facebook use is associated with eight major psychological effects (perceived anxiety, perceived depression, perceived loneliness, perceived eating disorders, perceived self-esteem, perceived life satisfaction, perceived insomnia, and perceived stress) and three physiological effects (physiological stress, human brain alteration, and affective experience state). The review also describes how Facebook use is associated with these effects and provides additional details on the reviewed literature, including research design, sample, age, and measures. Please note that the term "Facebook use" represents an umbrella term in the present work, and in the respective sections it will be made clear what kind of Facebook use is associated with a myriad of investigated psychological variables. Overall, findings indicate that certain kinds of Facebook use may come along with significant risks, both psychologically and physiologically. Based on our review, we also identify potential avenues for future research.

Do or Don't: Results of a Multinational Survey on Antibiotic Prophylaxis in Urodynamics.

Antibiotic prophylaxis contributes substantially to the increase in antibiotic resistance rates worldwide. This investigation aims to assess the current standard of practice in using antibiotic prophylaxis for urodynamics (UDS) and identify barriers to guideline adherence. An online survey using a 22-item questionnaire designed according to the Checklist for Reporting Results of Internet E-Surveys (CHERRIES) was circulated among urologists and gynecologists in Austria, Germany, and Switzerland between September 2021 and March 2022. A total of 105 questionnaires were eligible for analysis. Out of 105 completed surveys, most responders (n = 99, 94%) regularly perform dipstick urine analysis prior to urodynamics, but do not perform a urine culture (n = 68, 65%). Ninety-eight (93%) participants refrain from using antibiotic prophylaxis, and sixty-eight (65%) use prophylaxis if complicating factors exist. If asymptomatic bacteriuria is present, approximately 54 (52%) participants omit UDS and reschedule the procedure until antimicrobial susceptibility testing is available. Seventy-eight (78%) participants do not have a standard procedure for antibiotic prophylaxis in their department. Part of the strategy against the development of bacterial resistance is the optimized use of antibiotics, including antibiotic prophylaxis in urodynamics. Establishing a standard procedure is necessary and purposeful to harmonize both aspects in the field of urological diagnostics.

Non-Antibiotic Prophylaxis for Recurrent UTIs in Neurogenic Lower Urinary Tract Dysfunction (NAPRUN): Study Protocol for a Prospective, Longitudinal Multi-Arm Observational Study.

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.

Interruption science as a research field: Towards a taxonomy of interruptions as a foundation for the field.

Interruptions have become ubiquitous in both our personal and professional lives. Accordingly, research on interruptions has also increased steadily over time, and research published in various scientific disciplines has produced different perspectives, fundamental ideas, and conceptualizations of interruptions. However, the current state of research hampers a comprehensive overview of the concept of interruption, predominantly due to the fragmented nature of the existing literature. Reflecting on its genesis in the 1920s and the longstanding research on interruptions, along with recent technological, behavioral, and organizational developments, this paper provides a comprehensive interdisciplinary overview of the various attributes of an interruption, which facilitates the establishment of interruption science as an interdisciplinary research field in the scientific landscape. To obtain an overview of the different interruption attributes, we conducted a systematic literature review with the goal of classifying interruptions. The outcome of our research process is a taxonomy of interruptions, constituting an important foundation for the field. Based on the taxonomy, we also present possible avenues for future research.

[Do we need to treat asymptomatic bacteriuria in immunocompromised patients? : A rapid review]. / Soll die asymptomatische Bakteriurie bei Immunsupprimierten antibiotisch therapiert werden? : Ein Rapid Review.

BACKGROUND: Antimicrobial resistance (AMR), especially multidrug resistant Escherichia coli strains, is a problem even in Europe. That is why inadequate usage of antibiotic therapy should be avoided, especially in the treatment of asymptomatic bacteriuria (ASB). OBJECTIVES: Should ASB be treated with antibiotics in immunocompromized patients, namely solid organ transplant, especially kidney transplant or stem cell transplant recipients? MATERIALS AND METHODS: A rapid review based on a systematic literature search in MEDLINE between 1980 and 2022 was performed. For evidence synthesis, only randomized controlled trials (RCTs) or quasi-RCTs were considered. RESULTS: No studies were identified for the search term solid organ and stem cell transplantation. Three RCTs (antibiotic therapy versus no therapy) were included for adult kidney transplantation. None of the studies showed a benefit for antibiotic therapy of ASB in reduction of symptomatic urinary tract infections, especially in the late transplantation phase two months after kidney transplantation; furthermore, this therapy may promote AMR development. In addition, there are numerous gaps of evidence, e.g., in pediatric transplantation or regarding the influence of special immunosuppressants. CONCLUSION: There is no evidence for antibiotic therapy of ASB in adult kidney transplantation two months after the surgery. Further studies addressing the identified evidence gaps are essential for the prevention of further AMR development.

Practice Patterns in Fournier's Gangrene in Europe and Implications for a Prospective Registry Study.

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.

[What is the proportion of infectiology in the specialization urology? : A pilot study to underline the significance of Antibiotic Stewardship in urology]. / Welchen Anteil hat die Infektiologie am Fachgebiet Urologie? : Ein Pilotprojekt, zur Hervorhebung der Antibiotic-Stewardship-Bedeutung.

BACKGROUND: Urinary tract infections account for one of the most bacterial infectious diseases worldwide. OBJECTIVES: The primary aim of this pilot project was to identify the relative percentage of antibiotic use in comparison to all patients in a university medical center for the better establishment of antibiotic stewardship (ABS) programs. MATERIAL AND METHODS: This is an epidemiological pilot project. In the time period of three months it was evaluated which relative percentage of the patients was treated with antibiotics for bacterial urinary tract infection in comparison to all patients. RESULTS: In summary, about 40% of all urological patients received an antibiotic treatment against urinary tract infections or as perioperative prophylaxis against bacterial infection in the operating room (OR). The antibiotic use at the urological ward is highest in comparison to ambulance or OR. CONCLUSION: Infectious diseases, especially bacterial infections, account for a significant part of urology. This knowledge is essential to establish ABS programs and to tackle the progression of antibiotic resistance. Detailed studies are necessary to understand antibiotic prescription practice in urology to develop targeted ABS interventions.

[Urosepsis-targeted diagnostics and effective therapy]. / Urosepsis ­ sicher diagnostizieren und effektiv behandeln!

Urinary tract infections (UTIs) are characterized by a broad clinical presentation ranging from uncomplicated cystitis to septic shock. 9-31% of all septicemias have a urogenital focus and are referred to as urosepsis. Urosepsis often occurs in the context of health system-associated infections. Obstructive uropathy (e.g., urolithiasis, tumors, strictures) is a major risk factor. The severity and course of urosepsis depend not only on the pathogenicity of the pathogen but also on the type and extent of the individual immune response. Therapy is divided into causal (antimicrobial therapy and focal sanitation), supportive (hemodynamic and pulmonal stabilization), and adjunctive (glucocorticoid and insulin therapy) therapy and should be initiated without delay. Due to demographic change, a further increase in urosepsis is expected in the future, so every urologist should be familiar with targeted diagnostics and effective therapy.

[Urologic Emergencies: Paraphimosis]. / Urologische Notfälle: Paraphimose.

Urologic Emergencies: Paraphimosis Abstract. Paraphimosis presents a rare but acute urological emergency whereby the foreskin becomes entrapped behind the coronary sulcus of the penis. Therapy is quick and feasible, even in an outpatient setting. In most cases compression of the preputial edema and subsequent reposition of the prepuce is sufficient. Rarely, surgical intervention in form of a dorsal incision of the constriction is required. With partial or full phimosis being the underlying condition, paraphimosis occurs predominantly in infants and toddlers. However, persistent or secondary phimosis can lead to paraphimosis in advanced age.

Continent diversion: five decades of developments and evolution.

OBJECTIVE: To provide a chronological overview of the evolution of continent urinary diversion (CUD) over the last 50 years and to highlight important milestones. METHODS: We performed an extensive literature review and analysed different forms of urinary diversion worldwide. After the evaluation of surgical techniques, we assessed the advantages and disadvantages of assorted CUD approaches based on published long-term follow-up data. RESULTS: A wide variety of surgical options for CUD is available and feasible to date, although consensus among urologists regarding the 'gold standard' is still lacking. Several forms of orthotopic bladder substitutes and continent cutaneous urinary reservoirs have been shown to provide excellent long-term results. CONCLUSION: The last 50 years of CUD have seen constant evolution and refinement of techniques, but the best surgical approach remains unclear and there is no 'one-size-fits-all' option, but rather tailor-made approaches are necessary to ensure patient satisfaction.
