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

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.

BACKGROUND: The evolution of resistant pathogens is a worldwide health crisis and adherence to European Association of Urology (EAU) guidelines on antibiotic prophylaxis may be an important way to improve antibiotic stewardship and reduce patient harm and costs. OBJECTIVE: To evaluate the prevalence of antibiotic-resistant bacterial strains and health care costs during a period of adherence to EAU guidelines in a tertiary referral urologic institution. DESIGN, SETTING, AND PARTICIPANTS: A protocol for adherence to EAU guidelines for antibiotic prophylaxis for all urologic procedures was introduced in January 2011. Data for 3529 urologic procedures performed between January 2011 and December 2013 after protocol introduction were compared with data for 2619 procedures performed between January 2008 and December 2010 before protocol implementation. The prevalence of bacterial resistance and health care costs were compared between the two periods. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The outcome measures were the proportion of resistant uropathogens and costs related to antibiotic consumption and symptomatic postoperative infection. We used χ2 and Fisher's exact tests to test the significance of differences. RESULTS AND LIMITATIONS: The proportion of patients with symptomatic postoperative infection did not differ (180/3529 [5.1%] vs. 117/2619 [4.5%]; p=0.27). A total of 342 isolates from all patients with symptomatic postoperative infections were analysed. The rate of resistance of Escherichia coli to piperacillin/tazobactam (9.1% vs. 5.4%; p=0.03), gentamicin (18.3% vs. 11.2%; p=0.02), and ciprofloxacin (32.3% vs. 19.1%; p=0.03) decreased significantly after protocol introduction. The defined daily dose (DDD) use of ciprofloxacin fell from 4.2 to 0.2 DDD per 100 patient-days after implementation (p<0.001). Antibiotic drug costs (76,980 vs. 36,700) and costs related to postoperative infections (45,870 vs. 29,560) decreased following introduction of the protocol (p<0.001). CONCLUSIONS: Adherence to EAU guidelines on antibiotic prophylaxis reduced antibiotic usage without increasing post-operative infection rate and lowered the prevalence of resistant uropathogens. PATIENT SUMMARY: We analysed the impact of adherence to European Association of Urology guidelines on antibiotic prophylaxis for all surgical urologic procedures on the prevalence of infections and resistant bacterial strains and on costs. We found that adherence to the guidelines reduced the rate of bacterial resistance, in particular against piperacillin/tazobactam, gentamicin, and ciprofloxacin, and reduced costs without increasing the risk of postoperative infection after urologic procedures. We recommend adherence to the guidelines as an important part of antibiotic stewardship programmes.

INTRODUCTION: Penile implant patients are required to remain in the hospital after the operation for monitoring, antibiotic and analgesia administration. Cost containment, however, has resulted in the increased use of ambulatory surgery settings for many surgical procedures. Few studies have studied the feasibility of performing penile prosthesis insertion in an outpatient setting. The results are controversial and nowadays, in the most of centers that deal with prosthetic surgery, patients are still hospitalized. AIM: The aim of our investigation was to compare the feasibility of the performance as well as the complication profiles of penile implant surgery performed in an in-patient and an outpatient setting at a single center by a single surgeon. METHODS: From January 2009 to June 2014, 50 patients of the same uro-andrological unit underwent penile prosthesis implantation performed by a single surgeon (N.M.). Twenty implantations were performed in an ambulatory day surgery setting. MAIN OUTCOME MEASURES: Effectiveness and costs of outpatient setting versus the in-patient setting of the penile prosthesis surgery. RESULTS: There were some differences between the two groups in the intra-operative parameters, such as, operating time. Time lost from work was similar in both groups approximating 14 days. The mean number of analgesic pills ingested by the patients post-operatively was similar in both groups, averaging just under 25 pills per patient. There weren't post-operative complications in the outpatient group. Cost were 17% less in outpatient clinic. CONCLUSIONS: The outpatient setting for this surgery is safe and effective even in patients with comorbidities or in case of secondary procedures. Costs are reduced by 17%.
RESUMO
OBJECTIVE: To assess both the acceptance and the discontinuation rates from dapoxetine, the first oral pharmacological agent indicated for the treatment of premature ejaculation (PE). METHODS: One hundred twenty consecutive potent patients (mean age 40.3 years; range 18-63 years) seeking medical treatment for lifelong PE were enrolled in a prospective phase II study. Moreover, they were assessed regarding detailed medical and sexual history, intravaginal ejaculatory latency time (IELT), International Index of Erectile Function (IIEF), and complete physical examination. The patients received a dapoxetine prescription (30 mg on demand) and unresponded cases received increased dose (60 mg after 3 months). The patients were evaluated at 1, 3, 6, and 12 months, and requested to complete a multiple-choice global assessment questionnaire regarding specific reasons for eventual therapy discontinuation. RESULTS: Twenty-four of the patients (20%) decided not to start dapoxetine. Fear of using a "drug" was the most frequently reported reason for treatment nonacceptance (50%) and the cost of treatment was the reason for 25% of the patients. Ninety-six patients (80%) started the therapy. Twenty-six percent dropped out after 1 month, 42.7% dropped out after 3 months, 18.7% dropped out at 6 months, 2% dropped out at 12 months, and 10.4% are continuing the therapy after 1 year. The main reasons were effect below expectations 24.4%, costs 22.1%, side effects 19.8%, loss of interest in sex 19.8%, and no efficacy 13.9%. CONCLUSION: Twenty percent of lifelong PE patients seeking medical treatment for early ejaculation freely decided not to start treatment with dapoxetine, and roughly 90% of the patients who started therapy discontinued after 1 year.

PURPOSE: Several urinary markers have been recently introduced in clinical practice for improving the noninvasive diagnosis of transitional cell carcinoma. Although microsatellite analysis must be considered the best method in terms of results, its cost and method time are unacceptable for daily use. We validated a more rapid and inexpensive method of determination using rapid DNA extraction and automatic multiplex polymerase chain reaction amplification. MATERIALS AND METHODS: A total of 120 patients who presented consecutively to a urological office, including 73 with transitional cell carcinoma and 43 who served as controls, were selected for study. Microsatellite analysis was performed in the blood/urine pair using 3 multiplex polymerase chain reactions per patient. Urine sediment inflammatory cells were assessed by urine dipstick test. Ten microsatellite loci were investigated. Numerical data collected during electrophoresis of the amplified segment in an ABI Prism 310 Genetic Analyzer were used to calculate the cutoff for allelic imbalance. Method sensitivity, specificity, and positive and negative predictive values were calculated. RESULTS: A total of 66 patients had microsatellite analysis alterations in urine sediment, of whom 59 had transitional cell carcinoma, while 7 had other urological diseases. Test sensitivity and specificity were 80.8% and 85.1%, respectively. Statistical analysis did not indicate any significant influence of inflammatory status on microsatellite analysis diagnostic performance. In the control group the allelic imbalance on chromosome 9 was significantly lower than on other chromosomes (p = 0.0143). This could confirm that chromosome 9 has a specific role in transitional cell carcinoma. The multiplex microsatellite analysis method was low cost and not time-consuming. CONCLUSIONS: Multiplex microsatellite analysis is a noninvasive, rapid, inexpensive and reproducible method for screening for and monitoring superficial transitional cell carcinoma. It should be considered an alternative method to urinary cytology and it should also be considered in the presence of urine sediment inflammatory cells.
