Abstract
More than 70% of hospital-acquired urinary tract infections are related to urinary catheters, which are commonly used for the treatment of about 20% of hospitalized patients. Urinary catheters are used to drain the bladder if there is an obstruction in the tube that carries urine out of the bladder (urethra). During catheter-associated urinary tract infections, microorganisms rise up in the urinary tract and reach the bladder, and cause infections. Various materials are used to fabricate urinary catheters such as silicone, polyurethane, and latex. These materials allow bacteria and fungi to develop colonies on their inner and outer surfaces, leading to bacteriuria or other infections. Urinary catheters could be modified to exert antibacterial and antifungal effects. Although so many research have been conducted over the past years on the fabrication of antibacterial and antifouling catheters, an ideal catheter needs to be developed for long-term catheterization of more than a month. In this review, we are going to introduce the recent advances in fabricating antibacterial materials to prevent catheter-associated urinary tract infections, such as nanoparticles, antibiotics, chemical compounds, antimicrobial peptides, bacteriophages, and plant extracts.

Abstract
OBJECTIVE A systematic review on meatal cleaning prior to urinary catheterisation and post catheterisation and reduces the risk catheter-associated urinary tract infections (CAUTIs) and bacteriuria was published in 2017, with further studies undertaken since this time. The objective of this paper is to present an updated systematic review on the effectiveness of antiseptic cleaning of the meatal area for the prevention of CAUTIs and bacteriuria in patients who receive a urinary catheter. DESIGN Systematic review. DATA SOURCES Electronic databases Cochrane Library, PubMed, Embase, The Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline and Academic Search Complete were searched from 1 January 2016 and 29 February 2020. ELIGIBILITY CRITERIA Randomised controlled trials (RCTs) and quasi-experimental studies evaluating the use of antiseptic, antibacterial or non-medicated agents for cleaning the meatal, periurethral or perineal areas before indwelling catheter insertion or intermittent catheterisation or during routine meatal care. DATA EXTRACTION AND SYNTHESIS Data were extracted using the Cochrane Collaboration's data collection form for RCTs and non-RCTs. Data were extracted by one researcher and then checked for accuracy by a second researcher. RESULTS A total of 18 studies were included. Some potential benefit of using antiseptics, compared with non-antiseptics for meatal cleaning to prevent bacteriuria and or CAUTI was identified (OR 0.84, 95% CI 0.69 to 1.02; p=0.071). Antiseptics (chlorhexidine or povidine-iodine) may be of value for meatal cleaning on the incidence of CAUTI, compared with comparator agents (saline, soap or antimicrobial cloths) (OR=0.65, 95% CI 0.42 to 0.99; p=0.047). CONCLUSION There is emerging evidence of the role of some specific antiseptics (chlorhexidine) prior to urinary catheterisation, in reducing CAUTIs, and some potential benefit to the role of antiseptics more generally in reducing bacteriuria.

Abstract
BACKGROUND Updating the pathogenesis of catheter-associated bacteriuria (CA-bacteriuria) in the intensive care unit (ICU) is needed to adapt prevention strategies. Our aim was to determine whether the main pathway of CA-bacteriuria in ICU patients was endoluminal or exoluminal. In a prospective study, quantitative urine cultures were sampled from catheter sampling sites, collector bags and the catheter outer surface near the meatus from days 1 to 15 after catheterization. The endoluminal pathway was CA-bacteriuria (defined as 102 CFU/mL) first in collector bags and then in catheters. The exoluminal pathway was CA-bacteriuria first in catheters, on day 1 in early cases and after day 1 in late cases. RESULTS Of 64 included patients, 20 had CA-bacteriuria. Means of catheterization days and incidence density were 6.81 days and 55.2/1000 catheter-days. Of 26 microorganisms identified, 12 (46.2%) were Gram positive cocci, 8 (30.8%) Gram negative bacilli and 6 yeasts. Three (11.5%) CA-bacteriuria were endoluminal and 23 (88.5%) exoluminal, of which 10 (38.5%) were early and 13 (50%) late. Molecular comparison confirmed culture findings. A quality audit showed good compliance with guidelines. CONCLUSION The exoluminal pathway of CA-bacteriuria in ICU patients predominated and surprisingly occurred early despite good implementation of guidelines. This finding should be considered in guidelines for prevention of CA-bacteriuria.

Abstract
Introduction and hypothesis Urinary tract infection is the most common complication after urodynamic studies (UDS). Practice guidelines recommend against antibiotic prophylaxis based on an outdated review of the literature, which advised on the premise of “a lack of good quality studies” and based on an assumed low incidence not consistently supported by the literature. Objectives This systematic review aims to update the assessment of the efficacy of antibiotic prophylaxis compared with placebo or no treatment for prevention of urinary tract infection in females over the age of 18 years undergoing UDS. Methods MEDLINE, EMBASE, COCHRANE, DISSERTATIONS, conference proceedings and clinical trial registries were searched for relevant randomized controlled trials. Two authors independently screened and selected articles, assessed these for quality according to Cochrane guidelines and extracted their data. Results A total of 2633 records were screened, identifying three relevant randomized controlled trials. The one study that was critically appraised as being the least likely biased showed a statistically significant effect of antibiotic prophylaxis in reducing bacteriuria post UDS in female patients. The other two studies included in the review did not. None of the studies included were powered to show a significant change in the incidence of urinary tract infection following UDS in female patients receiving antibiotic prophylaxis versus no prophylaxis. Conclusions Similar to the 2012 Cochrane review on this subject, this systematic review demonstrated that antibiotic prophylaxis may decrease bacteriuria in women post UDS; however, further research is required to assess its effect on urinary tract infections in this context.

Abstract
STUDY DESIGN Retrospective cohort of patients with traumatic spinal cord injury (SCI) that have been hospitalized for physical-functional rehabilitation purposes. OBJECTIVES To compare the incidence of urinary tract infection (UTI) after urodynamic study (UDS) in three hospitals that adopted different protocols with regard to the preparation of patients. SETTING Sarah Network of Rehabilitation Hospitals, Brazil. MATERIALS AND METHODS Between 2014 and 2015, 661 patients from three units of the same hospital network, one of which does not use antimicrobial prophylaxis independently of urine culture results, were evaluated after having undergone UDS. The results were compared in both univariate and multivariate analyses (logistic regression). RESULTS The global rate of UTI after UDS was that of 3.18% (IC 95% 2.1-4.8), with no differences between the units. In the univariate analysis the only variable that was associated with UTI after UDS was that of T6 injuries or above (P = 0.029). The logistic regression has confi rmed this result, with an adjusted odds ratio of 3.06 (IC 95% 1.01 to 9.26; P = 0.0476). The use of antimicrobial prophylaxis did not alter that risk. CONCLUSIONS This study has demonstrated that the use of antimicrobials does not prevent UTI after UDS. Patients with T6 traumatic SCI or above have got three times more chance of developing UTI after UDS if compared to those with a T7 injury or below, independently of the use of antimicrobials. Even in these patients the use of antimicrobials would not be justified.

Abstract
Urinary tract infections due to the presence of a urinary catheter represent a real problem for patients who have to carry such an invasive device for a long time.Our aim was to identify the susceptibility of extended spectrum beta lactamases (ESBL) versus non-ESBL bacteria to antibiotics in urinary tract infections in patients who are chronic carriers of urinary catheters.The retrospective study included a period of 5 years, a total of 405 patients who are chronic carriers of urinary catheters, admitted to rehabilitation and palliative care units.Escherichia coli (E coli) was isolated in 41.2% of patients, Klebsiella pneumoniae (K pneumoniae) in 24.7%, and Proteus mirabilis (P mirabilis) in 15.3%. E coli microbial resistance rates ranged from a minimum of 7.5% (nitrofurantoin) to a maximum of 77.1% (ampicillin). In the case of K pneumoniae, microbial resistance ranged from 34.2% (netilmicin) to 73.2% (ceftriaxone). Resistance rates of P mirabilis ranged from 11.1% (cefepim) to 89.5% (ampicillin). Positivity of ESBL bacteria was identified in 47.4% of patients. Resistance rates of ESBL-positive E coli ranged from 50.0% (ceftriaxone) to 88.1% (cefepime), and ESBL-negative E coli rates ranged from 3.4% (cefepime) to 64.4% (amikacin). Resistance rates of ESBL-positive K pneumoniae ranged between 39.1% (netilmicin) and 85.1% (ceftriaxone), and ESBL-negative K pneumoniae between 7.1% (cefepime) and 53.3% (amikacin). In cases of ESBL-positive P mirabilis, rates ranged from 13.3% (cefepime) to 90.3% (ceftriaxone), whereas in cases of ESBL-negative P mirabilis, rates ranged between 8.3% (cefepime) and 80.0% (trimetroprim).Bacteriuria and asymptomatic catheter infection in chronic carriers is an important public health concern due to the frequent presence of multidrug-resistant bacteria. Our study highlights the need to develop control programs of catheter infections to minimize the risk of infections associated with these medical devices, and also the need for treatment of the infection rather than catheter colonization or contamination.

Abstract
INTRODUCTION To determine if a povidone iodine rectal preparation (PIRP) reduces rates of bacteriuria and bacteremia following transrectal ultrasound guided prostate needle biopsy (TRUS PNB). MATERIALS AND METHODS Men undergoing TRUS PNB were prospectively enrolled in a study comparing the impact of PIRP versus standard of care (two pills of ciprofloxacin 500 mg). Urine, blood, and rectal cultures were obtained 30 minutes post-procedure with colony forming units (CFUs) determined after 48 hours. Patients were called 7 and 30 days post-procedure to evaluate for infections. RESULTS A total of 150 men were accrued into this study including 95 receiving PIRP and 55 the standard of care. Two-thirds of patients were undergoing an initial biopsy, 19% used antibiotics within the previous 6 months, and median number of biopsy cores was 14. There were no differences between the two cohorts with respect to baseline or biopsy characteristics. In the PIRP cohort, rectal cultures before and after PIRP administration noted a 97.2% reduction in microorganism colonies (2.4 x 10 5 CFU/mL versus 6.7 x 10³CFU/mL, p < 0.001). Mean urine bacterial counts following TRUS PNB were 1 CFU/mL for PIRP versus 7 CFU/mL for standard cohort (p < 0.001). Mean serum bacterial counts following TRUS PNB were 0 CFU/mL for PIRP versus 3 CFU/mL for standard of care (p = 0.01). One patient in the PIRP cohort (1.1%) developed post-biopsy sepsis while 3 (5.5%) in the standard cohort had an infectious complication (1 UTI, 2 sepsis). CONCLUSION A PIRP regimen reduced bacteruria and bacteremia following TRUS PNB.

Abstract
The efficacy of antibiotic prophylaxis in radical prostatectomy (RP) remains to be established. We retrospectively compared the occurrence of perioperative infections after RP between the 2 different antibiotic protocols. This study involved 428 cases of laparoscopic radical prostatectomy (LRP). After excluding patients who had no perioperative urine culture data, 313 consecutive patients who underwent LRP for prostate carcinoma were classified into 2 groups according to the duration of antimicrobial prophylaxis. To group 1 (153 patients), a second-generation cephalosporin was administered for less than 2 days, whilst the remaining 160 patients in group 2 were administered the drug for more than 2 days. The overall incidence of postoperative bacteriuria was 50.8%, being significantly higher in group 1 (56.9%) than in group 2 (45%). The incidence of surgical site infection (SSI) was significantly higher in group 1 (5.2%) than in group 2 (0.6%). Multivariate analysis revealed that old age, duration of antibiotics for more than 2 days, and duration of Foley catheter placement were independently associated with postoperative infectious complications (all, P < 0.05). Multivariate analysis revealed that duration of antibiotics for more than 2 days, duration of Foley catheter placement, and duration of surgical drain placement were independently associated with postoperative SSI (all, P < 0.05). The incidence of postoperative bacteriuria and SSI were higher in patients who received antibiotics for a short duration. Based on our results, we demonstrated that the outcome of postoperative infectious complications is dependent on old age, short antibiotic administration duration, and prolonged Foley catheterization. Prolonged drain placement is associated with SSI, whilst a longer duration of antibiotics use and prolonged Foley catheterization are associated with a decrease in the incidence of SSI.

Abstract
PURPOSE The aim of this study is to determine whether antibiotic prophylaxis is required in this outpatient procedure. MATERIALS AND METHODS A non-randomised, prospective observational study that included 184 patients subjected to flexible cystoscopy divided into three groups: - Group 1:60 patients with prophylaxis of 500 mg of ciprofloxacin;- Group 2:62 patients with prophylaxis of 3 g of phosphomycin; and Group 3:62 without antibiotic prophylaxis. Prior to inclusion in the study, absence of infection was checked by means of a urine culture obtained 7 days before the procedure. An analysis was made of urinary infection after 7 days, the cystoscopy indications and its diagnosis, the presence of comorbidities, and the urinary symptoms during the following 7 days. RESULTS The mean age of the patients in Group 1 was 65.3 (SD: 12.5) years, 66.7 (10.8) years in Group 2, and 66.9 (10.8) years in Group 3 (P = .7). Bacteriuria was present in 15% of the patients in Group 1, compared to 22.6% in Group 2, and 12.9% in Group 3, with the differences not statistically significant. In multivariate analysis, it was observed that there was no association with the appearance of bacteriuria between the groups for age (P = .8), diabetes (P = .2), smoking (P = .4), lower urinary tract symptoms (P = .7), or immunosuppression (P = .6). CONCLUSION The use of ciprofloxacin or phosphomycin as prophylaxis does not appear to be indicated in flexible cystoscopy in our health area.

Abstract
PURPOSE OF THE STUDY A very serious complication following joint replacement surgery is periprosthetic joint infection that can be caused by a urinary tract infection. Insertion of an indwelling urinary catheter constitutes a risk factor that may result in urinary tract infections. The aim of this prospective randomised study was to compare the occurrence of significant bacteriuria and symptomatic urinary tract infections during antibiotic prophylaxis at the time of removal of an indwelling urinary catheter by cotrimoxazole in two doses and with no administration of antibiotics. We also monitored the incidence of potential periprosthetic infection following the endoprosthesis implantation. The findings of preoperative urine tests were compared with the declared negative preoperative examination. MATERIAL AND METHODS The study included patients indicated for a total hip or knee replacement with a negative urine culture as a part of the preoperative testing. Where leukocyteria was detected, urine culture by mid-stream clean catch urine was obtained. The second part included patients, in whom an indwelling urinary catheter had to be inserted postoperatively for urine retention and/or monitoring of fluid balance and who were divided into two groups on a rota basis. No antibiotics were administered to the first group, whereas Cotrimoxazol 960 mg tablets p.o. was administered to the second group, 14 and 2 hours before the removal of the catheter. The urine culture test was performed 4 hours after the removal of the indwelling urinary catheter, in both the groups. The test was repeated after 14 days and a questionnaire was filled in to report urinary tract complications. Considered as significant bacteriuria by urinalysis was the laboratory finding of > 10x4 CFU/ml in case of a single pathogen or > 10x5 in case of multiple pathogens. The results were statistically processed by Fischer's exact test with the level of significance = 0.05. RESULTS In the first part of the study leukocyturia was detected by a test strip in 112 of the total of 478 patients. In 10 women, significant bacteriuria was found. Altogether 50 women and 50 men were randomly assigned to the second part of the study. The indwelling urinary catheter was in place for 4 days on average. In men, no statistically significant difference was detected in significant bacteriuria findings, in women a statistically significant difference of p = 0.00162 was found after the removal and after 14 days the borderline of statistical significance of p = 0.0507 was achieved, but no symptomatic urinary tract infection was present. In the period from 20 to 32 months following the total joint replacement, no periprosthetic infection caused by urinary tract infection was reported. DISCUSSION There is enough evidence to prove the correlation between the symptomatic urinary tract infection and periprosthetic infection. On the other hand, asymptomatic bacteriuria is a common finding in patients before the planned hip of knee joint replacement and its treatment is not recommended. No consensus has been achieved as yet regarding the method of antibiotic prophylaxis for an inserted urinary catheter. Antibiotics are administered throughout the period of catheterisation by an indwelling urinary catheter, during its removal, or are not administered at all. In our study antibiotics were administered during the removal of an indwelling urinary catheter and a statistically significant difference was found in women. It concerned, however, only a higher incidence of asymptomatic bacteriuria not treated by antibiotics, which in the next follow-up period did not lead to periprosthetic infection. CONCLUSIONS Despite the negative pre-operative urine culture, frequent incidence of leukocyturia and symptomatic urinary infections were detected in a fairly high number of cases. Therefore, we recommend asking the patients during the hospital admission process specifically about the urinary infection symptoms. The results of our study show that antibiotic prophylaxis during the removal of indwelling urinary catheters placed for a short-term is unnecessary. Key words: endoprosthesis, urinary catheter, bacteriuria, urinary tract infection.

Abstract
OBJECTIVES It is unclear whether postoperative infections can be prevented by treating asymptomatic bacteriuria, or whether, on the other hand, such treatment will increase the risk of more serious infection by pathogenic bacteria different from the ones causing bacteriuria. This study aimed to support future treatment decisions for preoperative cardiothoracic surgery patients with asymptomatic bacteriuria, by examining current preoperative practice, in relation to postoperative outcome. METHODS A retrospective cohort study was conducted. All patients who underwent cardiothoracic surgery in 2011-2013 using extracorporeal circulation in St. Antonius Hospital Nieuwegein, and who preoperatively had nitrituria and/or leucocyturia were included. Exclusion criteria were C-reactive protein level higher than 10 mg/l, emergency surgery, critical preoperative state and/or antibiotic treatment because of other infections. Outcomes were postoperative infections and length of stay. Furthermore, we compared culture results of preoperative urine with postoperative infection sites in order to study the hypothesis of haematogenous spread. RESULTS One thousand and two patients with leucocyturia or nitrituria were eligible, of whom 3.9% had been treated with antibiotics preoperatively (AB+). Of the 96.1% of patients who had not been treated (AB-), 8.3% had an infection postoperatively, compared with 5.1% in the treatment (AB+) group. This was not statistically significant {odds ratio, corrected for EuroSCORE, 0.53 [95% confidence interval (CI) 0.12-2.24, P = 0.39]}. Length of stay, corrected for EuroSCORE, between the treated (AB+) and the non-treated (AB-) group did not differ, with a hazard ratio of 1.05 (95% CI 0.63-1.75, P = 0.85). As regards bacterial culture results, none of patients not treated with antibiotics preoperatively (AB-) seemed to have a postoperative infection due to haematogenous spread of bacteria from the urinary tract present preoperatively. CONCLUSIONS The risk of haematogenous spread of bacteria seems to be non-existent in this large cohort of non-treated patients, under our local clinical practice. Based on this current, best available evidence, it seems therefore safe not to treat patients with asymptomatic bacteriuria prior to cardiothoracic surgery. This could also imply that it is safe not to perform routine preoperative urine testing.

Abstract
CONTEXT AND OBJECTIVES Urinary tract infections are the most common cause of hospital-acquired infections, and the use of indwelling urinary catheters is a predisposing factor for their development. The aims of this study were to estimate the frequency of pre and postoperative bacteriuria, identify the microorganisms involved, count the colony-forming units, determine the antibiotic sensitivity profile and compare the results from pre and postoperative urinalyses among women undergoing gynecological surgery with implantation of a urinary catheter. DESIGN AND SETTING Non-controlled prospective observational single-cohort epidemiological study carried out at a university hospital. METHODS Urine samples were collected before and 24 hours after catheterization for urinalysis, culturing and antibiotic sensitivity testing. Pre and postoperative urinalyses were compared using Wilcoxon and McNemar non-parametric tests. RESULTS Fifty-one women participated in the study. Escherichia coligrew in six preoperative samples (11.8%) and Klebsiella pneumoniae in one (1.9%), but bacterial growth did not occur in any postoperative sample. Urinalysis showed lower number of pus cells in the postoperative urine samples (P < 0.05). There were no differences in red blood cell counts or in the nitrite and leukocyte esterase tests, between the samples. CONCLUSION Bacteriuria was found in 13.7% of the preoperative samples. Gram-negative bacteria sensitive to most antibiotics were identified. In the postoperative samples, no bacterial growth was observed. Urinalysis only showed significant reduction of leukocyturia in the postoperative period.

Abstract
BACKGROUND Flexible cystoscopy is a common test in clinical practice done with or without antibiotic prophylaxis. AIM To evaluate the efficacy of antibiotic prophylaxis with ciprofloxacin to reduce the incidence of urinary infection. MATERIAL AND METHODS Prospective, non-randomized observational study that included 60 patients divided into two groups. Group 1 received prophylactic ciprofloxacin 500 mg, one hour prior to the procedure and group 2 did not receive prophylaxis. The presence of bacteriuria, symptoms or signs of urinary infection or attending Emergency rooms or primary care for these symptoms were recorded during the seven days after the cystoscopy. RESULTS In groups 1 and 2, four and one patients had a positive urine culture, respectively. Only one patient in group 1 consulted in primary care for symptoms. No significant differences in symptoms or signs of urinary infection between groups were observed. CONCLUSIONS In this group of patients, antibiotic prophylaxis with ciprofloxacin 500 mg prior to cystoscopy had no benefit.

Abstract
Both urinary tract infection (UTI) and asymptomatic bacteriuria (ASB) are common problems among elderly adults and represent a significant health care burden. Despite their frequency, differentiating between ASB and true UTI remains controversial among health care providers. Several challenges exist in the evaluation of urinary symptoms in the elderly patient. Symptoms of UTI are variable; problems are encountered in the collection, testing, and interpretation of urine specimens; and results of urinalysis are often misinterpreted and mishandled. Multiple studies have shown no morbidity or mortality benefit to antibiotic therapy in either community or long-term care facility residents with ASB.

Abstract
BACKGROUND Recurrent urinary tract infections (RUTI) are common in women who are pregnant and may cause serious adverse pregnancy outcomes for both mother and child including preterm birth and small-for-gestational-age babies. Interventions used to prevent RUTI in women who are pregnant can be pharmacological (antibiotics) or non-pharmacological (cranberry products, acupuncture, probiotics and behavioural modifications). So far little is known about the best way to prevent RUTI in pregnant women. OBJECTIVES To assess the effects of interventions for preventing RUTI in pregnant women.The primary maternal outcomes were RUTI before birth (variously defined) and preterm birth (before 37 weeks). The primary infant outcomes were small-for-gestational age and total mortality. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (20 May 2015) and reference lists of retrieved articles. SELECTION CRITERIA Published, unpublished and ongoing randomised controlled trials (RCTs), quasi-RCTs, clustered-randomised trials and abstracts of any intervention (pharmacological and non-pharmacological) for preventing RUTI during pregnancy (compared with another intervention, placebo or with usual care). DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. MAIN RESULTS The review included one trial involving 200 women and was at moderate to high risk of bias.The trial compared a daily dose of nitrofurantoin and close surveillance (regular clinic visit, urine cultures and antibiotics when a positive culture was found) with close surveillance only. No significant differences were found for the primary outcomes: recurrent pyelonephritis (risk ratio (RR) 0.89, 95% confidence interval (CI) 0.31 to 2.53; one study, 167 women), RUTI before birth (RR 0.30, 95% CI 0.06 to 1.38; one study, 167 women), and preterm birth (before 37 weeks) (RR 1.18, 95% CI 0.42 to 3.35; one study, 147 women). The overall quality of evidence for these outcomes as assessed using GRADE was very low. There were no significant differences between the two comparison groups for any of the following secondary outcomes, birthweight less than 2500 (g) (RR 2.03, 95% CI 0.53 to 7.80; one study, 147 infants), birthweight (mean difference (MD) -113.00, 95% CI -327.20 to 101.20; one study, 147 infants), five-minute Apgar score less than seven (RR 2.03, 95% CI 0.19 to 21.87; one study, 147 infants) and miscarriages (RR 3.11, 95% CI 0.33 to 29.29; one study, 167 women). The evidence for these secondary outcomes was also of very low quality. The incidence of asymptomatic bacteriuria (ASB) (at least 10(3) colonies per mL) (secondary outcome), only reported in women with a clinic attendance rate of more than 90% (RR 0.55, 95% CI 0.34 to 0.89; one study, 102 women), was significantly reduced in women who received nitrofurantoin and close surveillance. Data on total mortality and small-for-gestational-age babies were not reported. AUTHORS' CONCLUSIONS A daily dose of nitrofurantoin and close surveillance has not been shown to prevent RUTI compared with close surveillance alone. A significant reduction of ASB was found in women with a high clinic attendance rate and who received nitrofurantoin and close surveillance. There was limited reporting of both primary and secondary outcomes for both women and infants. No conclusions can be drawn regarding the optimal intervention to prevent RUTI in women who are pregnant. Randomised controlled trials comparing different pharmacological and non-pharmacological interventions are necessary to investigate potentially effective interventions to prevent RUTI in women who are pregnant.

Abstract
PURPOSE OF INVESTIGATION T0 investigate how the regularity of checkups in pregnancy influences maternal behavior regarding habits in prevention of urinary tract infection (UTI), the level of information, and finally the prevalence of asymptomatic bacteriuria (AB). MATERIALS AND METHODS This study included 223 women with regular and 220 women with irregular checkups in pregnancy were given the questionnaire on the following issues: frequency of sexual intercourses during pregnancy, the regularity of bathing and changing of underwear, the direction of washing the genital region after urinating, the regularity of antenatal visits to gynecologist, and the subjective experience concerning the quality of the information received by the healthcare provider. RESULTS AB was present significantly more frequent in group of participants with irregular controls during pregnancy compared to group with regular checkups in pregnancy. The prevalence of AB was higher in those women who had irregular prenatal checkups. Maternal behaviors related with the risk of urinary infections are more frequent among women with irregular prenatal care. CONCLUSION Results of the present study emphasize the importance of regular prenatal care in AB prevention.

Abstract
IMPORTANCE Asymptomatic bacteriuria and symptomatic urinary tract infections (UTIs) in older women are commonly encountered in outpatient practice. OBJECTIVE To review management of asymptomatic bacteriuria and symptomatic UTI and review prevention of recurrent UTIs in older community-dwelling women. EVIDENCE REVIEW A search of Ovid (Medline, PsycINFO, Embase) for English-language human studies conducted among adults aged 65 years and older and published in peer-reviewed journals from 1946 to November 20, 2013. RESULTS The clinical spectrum of UTIs ranges from asymptomatic bacteriuria, to symptomatic and recurrent UTIs, to sepsis associated with UTI requiring hospitalization. Recent evidence helps differentiate asymptomatic bacteriuria from symptomatic UTI. Asymptomatic bacteriuria is transient in older women, often resolves without any treatment, and is not associated with morbidity or mortality. The diagnosis of symptomatic UTI is made when a patient has both clinical features and laboratory evidence of a urinary infection. Absent other causes, patients presenting with any 2 of the following meet the clinical diagnostic criteria for symptomatic UTI: fever, worsened urinary urgency or frequency, acute dysuria, suprapubic tenderness, or costovertebral angle pain or tenderness. A positive urine culture (≥105 CFU/mL) with no more than 2 uropathogens and pyuria confirms the diagnosis of UTI. Risk factors for recurrent symptomatic UTI include diabetes, functional disability, recent sexual intercourse, prior history of urogynecologic surgery, urinary retention, and urinary incontinence. Testing for UTI is easily performed in the clinic using dipstick tests. When there is a low pretest probability of UTI, a negative dipstick result for leukocyte esterase and nitrites excludes infection. Antibiotics are selected by identifying the uropathogen, knowing local resistance rates, and considering adverse effect profiles. Chronic suppressive antibiotics for 6 to 12 months and vaginal estrogen therapy effectively reduce symptomatic UTI episodes and should be considered in patients with recurrent UTIs. CONCLUSIONS AND RELEVANCE Establishing a diagnosis of symptomatic UTI in older women requires careful clinical evaluation with possible laboratory assessment using urinalysis and urine culture. Asymptomatic bacteriuria should be differentiated from symptomatic UTI. Asymptomatic bacteriuria in older women should not be treated.

Abstract
OBJECTIVE To determine whether antibiotic prophylaxis can reduce the risk of postoperative infective complications in patients undergoing percutaneous nephrolithotomy (PCNL) who have sterile preoperative urine. METHODS MEDLINE, EMBASE, Cochrane Collaboration Reviews, CMCC and CNKI were searched for RCTs comparing antibiotic prophylaxis with placebo (or blank controls) for patients undergoing PCNL with preoperative sterile urine. The search strategy was made according to the Collaborative Review Group search strategy. Data were extracted by 2 reviewers using the designed extraction form. The software RevMan 4.2 was used to review management and data analysis. RESULTS A total of 9 trails, 1 placebo controlled, 3 non treatment controlled, and 5 active controlled, involving 1018 patients, met the inclusion criteria. Prophylactic antibiotic use in patients at low risk undergoing PCNL significantly decreased fever (RR = 0.71, 95% CI: 0.54-0.92, P = 0.009), bacteriuria (RR = 0.39, 95%CI: 0.23-0.67, P = 0.0006) and bacteremia incidence (RR = 0.43, 95%CI: 0.25-0.73, P = 0.002). Effective antibiotic classes included quinolone which significantly decreased bacteriuria incidence (RR = 0.31, 95%CI: 0.12-0.82, P = 0.010) and nitrofurantoin which significantly decreased fever incidence (RR = 0.38, 95%CI: 0.24-0.61, P = 0.005). Extended course significantly decreased fever incidence (RR = 0.64, 95%CI: 0.47-0.87, P = 0.004) and bacteriuria incidence (RR = 0.35, 95%CI: 0.18-0.71, P = 0.003). CONCLUSIONS Prophylactic antibiotics can significantly decrease the incidence of postoperative infective complications. A significant decrease in bacteriuria incidence can be achieved with quinolones. Extended course is effective in decreasing fever, and bacteriuria incidence.

Abstract
The aim of the study is identification of urinary tract infections (UTI) and urinary tract anomalies (UTA) already in the perinatal period. The authors attempted to prevent serious consequences of the above conditions in the examined children. Family history data, certain conditions in pregnancy and appertaining symptoms in children were elaborated to specify selective distinctive criteria for children at risk. Newborns (1200) were selected for potential existence of a UTI. All the examined newborns underwent a urinalysis. Those with significant bacteriuria were taken urine specimens, C-reactive protein (RVP), Complete Blood Count (CBC) and bilirubin. The newborns with a UTI and a suspected UTA were sent to ultrasound examination, direct radio nuclide cystography and Tc99m MAG3 dynamic scanning. The frequency of a UTI in the perinatal period amounted to 4.5%. A UTA was found in 29.6% of the examinees. The infection was more likely to appear among newborns with a UTA in their families, a UTI, pre-eclampsia and a febrile infection in mother, intrauterine growth retardation, premature rupture of membranes (RVP), umbilical cord strangulation, jaundice, cyanosis, breathing difficulties, seizures and asphyxia.

Abstract
The objective of this multicenter, randomized, controlled, parallel group trial was to evaluate the efficacy of levofloxacin 250 mg oral, once daily (LVFX), placebo one tablet oral once daily (Placebo [P] group) and ciprofloxacin (CPFX) 500 mg oral, twice daily (single blind), prophylaxis in preventing bacteriuria (> or = 10(3) CFU/ml) in post-surgical catheterized patients. In the modified intention-to-treat (M-ITT) population of the 82 enrolled patients, negative bacteriuria was observed in 92% of LVFX group, in 80% of P group and in 100% of CPFX group while in the per-protocol (PP) population figures were: 100%, 86.4% and 100% respectively. Only one symptomatic urinary tract infection and one surgical wound infection were observed in the P group. Both drugs were well tolerated, showing a safety profile comparable to placebo. The high frequency of negative bacteriuria in the placebo group sounds encouraging as it underlines that the adoption of closed urinary drainage system catheters in hospital setting may reduce the frequency of hospital-acquired infections.

SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (8 June 2012) and reference lists of retrieved articles. SELECTION CRITERIA Published, unpublished and ongoing randomised controlled trials (RCTs), quasi-RCTs, clustered-randomised trials and abstracts of any intervention (pharmacological and non-pharmacological) for preventing RUTI during pregnancy (compared with another intervention, placebo or with usual care). DATA COLLECTION AND ANALYSIS Two review authors independently evaluated the one identified trial for inclusion and assessed trial quality. Two review authors extracted data. Data were checked for accuracy. MAIN RESULTS The review included one trial involving 200 women. The trial compared a daily dose of nitrofurantoin and close surveillance (regular clinic visit, urine cultures and antibiotics when a positive culture was found) with close surveillance only. No significant differences were found for the primary outcomes: recurrent pyelonephritis (risk ratio (RR) 0.89, 95% confidence interval (CI) 0.31 to 2.53, one study, 167 women), recurrent urinary tract infection before birth (RR 0.30, 95% CI 0.06 to 1.38; one study 167 women) and preterm birth (before 37 weeks) (RR 1.18, 95% CI 0.42 to 3.35; one study 147 women). The incidence of asymptomatic bacteriuria (ASB) (at least 10(3) colonies per mL) (secondary outcome), only reported in women with a clinic attendance rate of more than 90% (RR 0.55, 95% CI 0.34 to 0.89; one study, 102 women), was significantly reduced in women who received nitrofurantoin and close surveillance. AUTHORS' CONCLUSIONS A daily dose of nitrofurantoin and close surveillance has not been shown to prevent RUTI compared with close surveillance alone. A significant reduction of ASB was found in women with a high clinic attendance rate and who received nitrofurantoin and close surveillance. There was limited reporting of both primary and secondary outcomes for both women and infants. No conclusions can be drawn regarding the optimal intervention to prevent RUTI in women who are pregnant. Randomised controlled trials comparing different pharmacological and non-pharmacological interventions are necessary to investigate potentially effective interventions to prevent RUTI in women who are pregnant.

Abstract
BACKGROUND There is a risk that people who have invasive urodynamic studies (cystometry) will develop urinary tract infections or bacteria in the urine or blood. However, the use of prophylactic antibiotics before or immediately after invasive cystometry or urodynamic studies is not without risks of adverse effects and emergence of resistant microbes. OBJECTIVES To assess the effectiveness and safety of administering prophylactic antibiotics in reducing the risk of urinary tract infections after urodynamic studies. The hypothesis was that administering prophylactic antibiotics reduces urinary tract infections after urodynamic studies. SEARCH METHODS We searched the Cochrane Incontinence Group Specialised Trial Register, MEDLINE (January 1966 to January 2009), CINAHL (January 1982 to January 2009), EMBASE (January 1966 to January 2009), PubMed (1 January 1980 to January 2009), LILACS (up to January 2009), TRIP database (up to January 2009), and the UK NHS Evidence Health Information Resources (searched 10 December 2009). We searched the reference lists of relevant articles, the primary trials and the proceedings of the International Urogynaecological Association International Continence Society and the American Urological Association for the years 1999 to 2009 to identify articles not captured by electronic searches. There were no language restrictions. SELECTION CRITERIA All randomized controlled trials and quasi-randomized trials comparing the use of prophylactic antibiotics versus a placebo or no treatment in patients having urodynamic studies were selected. Two authors (PL and RF) independently performed the selection of trials for inclusion and any disagreements were resolved by discussion. DATA COLLECTION AND ANALYSIS All assessments of the quality of trials and data extraction were performed independently by two authors of the review (PL and RF) using forms designed according to Cochrane guidelines. We attempted to contact authors of the included trials for any missing data. Data were extracted on characteristics of the study participants including details of previously administered treatments, interventions used, the methods used to measure infection and adverse events.Statistical analyses were performed according to Cochrane Collaboration guidelines. Data from intention-to-treat analyses were used where available. For the dichotomous data, results for each study were expressed as a risk ratio (RR) with 95% confidence interval (CI) and combined for meta-analysis using the Mantel-Haenszel method.The primary outcome was urinary tract infection. Heterogeneity was assessed by the P value and I(2) statistic. MAIN RESULTS Nine randomized controlled trials involving the prophylactic use of antibiotics in patients having urodynamic studies were identified and these included 973 patients in total; one study was an abstract. Two further trials were excluded from the review. The methods of the included trials were poorly described.The primary outcome in all trials was the rate of developing significant bacteriuria, defined as the presence of more than 100,000 bacteria per millilitre of a mid-stream urine sample on culture and sensitivity testing. The other outcomes included pyrexia, haematuria, dysuria and adverse reactions to antibiotics.The administration of prophylactic antibiotics when compared to a placebo reduced the risk of significant bacteriuria (4% with antibiotics versus 12% without, risk ratio (RR) 0.35, 95% CI 0.22 to 0.56) in both men and women. The administration of prophylactic antibiotics also reduced the risk of haematuria (RR 0.46, 95% CI 0.23 to 0.91). However, there was no statistically significant difference in the primary outcome, risk of symptomatic urinary tract infection (40/201, 20% versus 59/214, 28%; RR 0.73, 95% CI 0.52 to 1.03); or in the risk of fever (RR 5.16, 95% CI 0.94 to 28.16) or dysuria (RR 0.83, 95% CI 0.5 to 1.36). Only two of 135 people had an adverse reaction to the antibiotics. The number of patients needed to treat with antibiotics to prevent bacteriuria was 12.3. Amongst women, the number needed to treat to prevent bacteriuria was 13.4; while amongst men it was 9.1 (number needed to treat = 1/ absolute risk reduction). AUTHORS' CONCLUSIONS Prophylactic antibiotics did reduce the risk of bacteriuria after urodynamic studies but there was not enough evidence to suggest that this effect reduced symptomatic urinary tract infections. There was no statistically significant difference in the risk of fever, dysuria or adverse reactions. Potential benefits have to be weighed against clinical and financial implications, and the risk of adverse effects.

Abstract
BACKGROUND People requiring long-term bladder draining commonly experience catheter-associated urinary tract infection and other problems. OBJECTIVES To determine if certain catheter policies are better than others in terms of effectiveness, complications, quality of life and cost-effectiveness in long-term catheterised adults and children. SEARCH METHODS We searched the Cochrane Incontinence Group Specialised Trials Register (searched 28 September 2011). Additionally, we examined all reference lists of identified trials. SELECTION CRITERIA All randomised and quasi-randomised trials comparing catheter policies (route of insertion and use of antibiotics) for long-term (more than 14 days) catheterisation in adults and children. DATA COLLECTION AND ANALYSIS Data were extracted by two reviewers independently and compared. Disagreements were resolved by discussion. Data were processed as described in the Cochrane Handbook. If the data in trials had not been fully reported, clarification was sought from the authors. When necessary, the incidence-density rates (IDR) and/or the incidence-density differences (IDD) within a certain time period were calculated. MAIN RESULTS Eight trials met the inclusion criteria involving 504 patients in four cross-over and four parallel-group randomised controlled trials. Only two of the pre-stated six comparisons were addressed in these trials. Four trials compared antibiotic prophylaxis with antibiotics when clinically indicated. For patients using intermittent catheterisation, there were inconsistent findings about the effect of antibiotic prophylaxis on symptomatic urinary tract infection (UTI). Only one study found a significant difference in the frequency of UTI favouring prophylaxis. For patients using indwelling urethral catheterisation, one small trial reported fewer episodes of symptomatic UTI in the prophylaxis group.Four trials compared antibiotic prophylaxis with giving antibiotics when microbiologically indicated. For patients using intermittent catheterisation, there was limited evidence that receiving antibiotics reduced the rate of bacteriuria (asymptomatic and symptomatic). There was weak evidence that prophylactic antibiotics were better in terms of fewer symptomatic bacteriuria. AUTHORS' CONCLUSIONS No eligible trials were identified that compared alternative routes of catheter insertion. The data from eight trials comparing different antibiotic policies were sparse, particularly when intermittent catheterisation was considered separately from indwelling catheterisation. Possible benefits of antibiotic prophylaxis must be balanced against possible adverse effects, such as development of antibiotic resistant bacteria. These cannot be reliably estimated from currently available trials.

Abstract
OBJECTIVES One of the main drawbacks of flexible urethrocystoscopy is the risk of urinary tract infection (UTI). In order to reduce this risk, antimicrobial prophylaxis has been considered, however there is not a unanimous view regarding indications, dosage, type of antibiotic, and so on. To clarify this uncertainty, we practiced a pilot and experimental study aimed at assessing the effectiveness of chemoprophylaxis with 3 grams of fosfomycin trometamol in the prevention of UTI after urethrocystoscopy. METHODS Sixty patients were entered into a pilot randomized clinical trial between March and August 2011. Thirty patients were assigned to a control group without receiving any antibiotic dose, and the intervention group (30 patients) received 3 g fosfomycin trometamol. Ten days later urine culture and sediment analysis were performed in all patients. Significant bacteriuria was considered from > 105 CFU /ml. One month later a telephone survey was developed to assess urinary symptoms, and assistance to the family doctor. We estimated the cumulative incidence of bacteriuria, pyuria and microhematuria in both groups, and we compared the results using a strategy of analysis per protocol and intention to treat. RESULTS The incidence of bacteriuria, pyuria and microhematuria in the control group was 10%, 23.3% and 26.7% respectively and in the intervention groups the values differed depending on the type of analysis. Considering only the 27 patients (per protocol analysis), the incidence would be 11.1%, 37.0% and 29.6% respectively. If we include the three patients who did not completed the study (per intention to treat analysis) and considering their results as negative, the results were 10%, 33.3% and 26.7% respectively. Finally, in the case the three cultures not performed in this group had produced a positive result, the impact would have been 20.0%, 43.3% and 36.7%. In any of the three cases, the differences with the control group were not statistically significant. CONCLUSIONS In a selected population and with appropriate aseptic measures, antibiotic chemoprophylaxis does not appear to show a clinically relevant reduction in the incidence of UTI in patients undergoing flexible urethrocystoscopy.

Abstract
BACKGROUND Transrectal prostate biopsy (TRPB) is a well established procedure used to obtain tissue for the histological diagnosis of carcinoma of the prostate. Despite the fact that TRPB is generally considered a safe procedure, it may be accompanied by traumatic and infective complications, including asymptomatic bacteriuria (bacteria in the urine), urinary tract infection (UTI), transitory bacteremia (bacteria in the blood), fever episodes, and sepsis (pathogenic microorganisms or their toxins in the blood). Although infective complications after TRPB are well known, there is uncertainty about the necessity and effectiveness of routine prophylactic antibiotics and their adverse effects, as well as a clear lack of standardization. OBJECTIVES To evaluate the effectiveness and adverse effects of prophylactic antibiotic treatment in TRPB. SEARCH STRATEGY The search covered the principal electronic databases: MEDLINE, EMBASE, LILACS and the Cochrane Central Register of Controlled Trials (CENTRAL). Experts were consulted and references from the relevant articles were scanned. SELECTION CRITERIA All randomized, controlled trials (RCTs) of men who underwent TRPB and received prophylactic antibiotics or placebo/no treatment, were selected, and all RCTs looking at one type of antibiotic versus another, including comparable dosages, routes of administration, frequency of administration, and duration of antibiotic treatment. DATA COLLECTION AND ANALYSIS Two reviewers (ELZ, OACC) independently selected included trials and extracted study data. Any disagreements were resolved by a third party (NRNJ). MAIN RESULTS Overall, more than 3500 references were considered and 19 original reports with a total of 3599 patients were included.There were 9 trials analysing antibiotics versus placebo/no treatment, with all outcomes significantly favouring antibiotic use (P < 0.05) (I(2) = 0%), including bacteriuria (risk ratio (RR) 0.25 (95% confidence interval (CI) 0.15 to 0.42), bacteremia (RR 0.67, 95% CI 0.49 to 0.92), fever (RR 0.39, 95% CI 0.23 to 0.64), urinary tract infection (RR 0.37, 95% CI 0.22 to 0.62), and hospitalization (RR 0.13, 95% CI 0.03 to 0.55). Several classes of antibiotics were effective prophylactically for TRPB, while the quinolones, with the highest number of studies (5) and patients (1188), were the best analysed. For 'antibiotics versus enema', we analysed four studies with a limited number of patients. The differences between groups for all outcomes were not significant. For 'antibiotic versus antibiotic + enema', only the risk of bacteremia (RR 0.25, 95% CI 0.08 to 0.75) was diminished in the 'antibiotic + enema group'. Seven trials reported the effects of short-course (1 day) versus long-course (3 days) antibiotics. Long course was significantly better than short-course treatment only for bacteriuria (RR 2.09, 95% CI 1.17 to 3.73). For 'single versus multiple dose', there was significantly greater risk of bacteriuria for single-dose treatment (RR 1.98, 95% CI 1.18 to 3.33). Comparing oral versus systemic administration - intramuscular injection (IM), or intravenous (IV) - of antibiotics, there were no significant differences in the groups for bacteriuria, fever, UTI and hospitalization. AUTHORS' CONCLUSIONS Antibiotic prophylaxis is effective in preventing infectious complications following TRPB. There is no definitive data to confirm that antibiotics for long-course (3 days) are superior to short-course treatments (1 day), or that multiple-dose treatment is superior to single-dose.

Abstract
This article looks at the anatomy of the bladder and how sensations, including pain, are transmitted to the brain. The use of urinary catheters is discussed and initially, the development of biofilm is addressed, from its cause, structure and effect, to how it can be treated. Many of the problems arising from biofilm and the resulting encrustation, can lead to pain, and the causes of this are discussed. Other problems which can cause patients to experience pain are also considered, and where there are possible solutions, these have been put forward. However, even when good practice is carried out, there will still be problems encountered, and further research is needed.

Abstract
OBJECTIVE To investigate whether antibiotic prophylaxis can reduce the risk of postoperative bacteriuria in patients undergoing transrectal prostatic biopsy (TPB) who have sterile preoperative urine. METHODS MEDLINE, EMBASE, Cochrane Collaboration Reviews, CMCC, and CNKI were searched for randomized controlled trials (RCTs) comparing antibiotic prophylaxis with placebo/blank controls for patients undergoing TPB with preoperative sterile urine. The search strategy was made according to the Collaborative Review Group search strategy. Data were extracted by two reviewers using the designed extraction form. The software RevMan4.2 was used to review management and data analysis. RESULTS 67 relevant RCTs were found, of which 12 qualified ones were included into the analysis. Antibiotic prophylaxis significantly decreased the rate of bacteriuria within the period 1 week after TPB (corresponding pooled relative risk (RR) and 95% CI was 0.32 (0.23 - 0.46, P < 0.01). The effective antibiotics included quinolones and quinolones combined with nitroimidazole, with the pooled RR and 95% CI of 0.31 (0.18 - 0.53, P < 0.01) and 0.32 (0.17 - 0.60, P = 0.0004) respectively. There was no significant difference in the effect between short treatment course protocol and long course protocol (P = 0.41). CONCLUSION Prophylactic antibiotics can significantly decrease the incidence of post-TPB bacteriuria. A significant decrease in bacteriuria incidence can be achieved with a range of antibiotic agents, including quinolones and-quinolones combined with nitroimidazole. Treatment protocols of any duration are effective.

Abstract
Urinary tract infections (UTIs) represent the second most often observed infectious diseases in community, following the respiratory tract infections. In the United States, these infections account for up to 7 million/year of visits, with a mean yearly expense for the related antibiotic treatment that has been estimated in more than one billion dollars. In nosocomial setting, UTIs represent the most frequent diseases, whose incidence equates 40% of nosocomial infections overall considered; about 80% of UTIs is related to urinary catheterization. In the present review, the authors, after a brief introduction about epidemiology, pathogenesis and aetiology of urinary tract infections, consider two particular settings: long term care facilities, where UTIs represent the most often diagnosed and treated infections, and the Intensive Care Units where occurrence of urinary tract infections represents an especially frequent event as well. Patients referred to both these settings are particular, as they undergo, in most cases, to urinary catheterization. After describing the pathogenesis of UTIs related to catheterization, either short- or long term, the authors consider the different currently available catheters, focusing on silver-coated and silver alloy coated (silver, gold, and platinum). With regard to this latter issue, results presented by a number of papers in the literature are reported, where clinical experiences following the use of these urinary catheters are described. In their conclusion, authors suggest the opportunity to increase any prevention strategy able to reduce the incidence of infections related to urinary catheterization and its consequences, as a more rational length and modality of catheterization, in addition to the use of innovative catheters.

Abstract
PURPOSE We compared the effects of daily cranberry juice cocktail to those of placebo during pregnancy on asymptomatic bacteriuria and symptomatic urinary tract infections. MATERIALS AND METHODS A total of 188 women were randomized to cranberry or placebo in 3 treatment arms of A-cranberry 3 times daily (58), B-cranberry at breakfast then placebo at lunch and dinner (67), and C-placebo 3 times daily (63). After 27.7% (52 of 188) of the subjects were enrolled in the study the dosing regimens were changed to twice daily dosing to improve compliance. RESULTS There were 27 urinary tract infections in 18 subjects in this cohort, with 6 in 4 group A subjects, 10 in 7 group B subjects and 11 in 7 group C subjects (p = 0.71). There was a 57% and 41% reduction in the frequency of asymptomatic bacteriuria and all urinary tract infections, respectively, in the multiple daily dosing group. However, this study was not sufficiently powered at the alpha 0.05 level (CI 0.14-1.39 and 0.22-1.60, respectively, incidence rate ratios). Of 188 subjects 73 (38.8%) withdrew, most for gastrointestinal upset. CONCLUSIONS These data suggest there may be a protective effect of cranberry ingestion against asymptomatic bacteriuria and symptomatic urinary tract infections in pregnancy. Further studies are planned to evaluate this effect.

Abstract
OBJECTIVE To report a large prospective, pragmatic, double-blind randomized controlled trial to determine whether oral prophylactic antibiotics reduce the risk of bacteriuria after flexible cystoscopy (FC), as up to 10% of patients develop urinary infection afterwards, with significant morbidity and costs for health services. PATIENTS AND METHODS In all, 2481 patients were recruited into a three-arm placebo controlled trial and 2083 completed it. Patients were randomly assigned to one of three treatments; (i) placebo; (ii) one oral dose of trimethoprim (200 mg); or (iii) one oral dose of ciprofloxacin (500 mg), each administered 1 h before a FC under local anaesthetic. A mid-stream urine specimen was taken before and 5 days after FC; significant bacteriuria was defined as a pure growth of >10(5) colony-forming units/mL. RESULTS The rate of bacteriuria after FC was reduced from 9% in the placebo group to 5% and 3% in patients receiving trimethoprim and ciprofloxacin prophylaxis, respectively. When rates of bacteriuria before FC were considered the odds of developing bacteriuria after FC relative to baseline were 5, 2 and 0.5 for placebo, trimethoprim and ciprofloxacin, respectively. CONCLUSION This large trial shows clearly that one dose of oral ciprofloxacin significantly reduces bacteriuria after FC.

Abstract
OBJECTIVE To investigate the frequencies, pathogen microorganisms involved, and possible risk factors of urinary tract infections, asymptomatic bacteriuria, and significant bacteriuria in subacute and chronic stroke patients. DESIGN The frequencies were determined and compared for subgroups with respect to age, gender, level of education, type of lesion, side of lesion, bladder-emptying method, postvoid residual urine, ambulation-level class, and Brunnstrom recovery stage class of upper and lower extremities in 110 consecutive stroke patients. RESULTS Frequencies were 27.3, 11.8, and 39.1% for urinary tract infections, asymptomatic bacteriuria, and significant bacteriuria, respectively. Bladder-emptying method (P < 0.05), presence of postvoid residual urine >50 ml (P < 0.04), and Brunnstrom recovery stage class of upper extremity (P < 0.02) were significant factors for the frequency of urinary tract infections. Bladder-emptying method, ambulation-level class, Brunnstrom recovery stage class of upper and lower extremities (P < 0.01), presence of postvoid residual urine >50 ml (P < 0.02), gender, and level of education (P < 0.05) were significant factors for the frequency of significant bacteriuria. CONCLUSIONS Early treatment of urinary dysfunction for elimination of indwelling catheter use and high postvoid residue, early physical rehabilitation for better ambulation and hand function, patient education about prevention, and close monitoring of patients with unmodifiable risk factors may decrease the frequency of urinary tract infections and significant bacteriuria in stroke patients.

Abstract
AIMS To assess the effectiveness and safety of administering prophylactic antibiotics in reducing the risk of urinary tract infection (UTI) after urodynamic studies (UDS). METHODS The CENTRAL, MEDLINE, EMBASE, CINAHI, LILIACS (up to January 2007), TRIP database, The National Library for Health, the citation lists of review articles, conference abstracts (2004-2006) and hand search of reference lists to identify relevant reviews and articles. Randomised controlled trials (RCTs) comparing effectiveness of prophylactic antibiotics with placebo or nothing in reducing bacteriologically proven UTI after invasive cystometry were included. Two reviewers extracted data independently and the results were expressed as peto odds ratio with 95% confidence intervals using fixed effects model in ReV Man 4.2.8 software. RESULTS Eight RCTs with 995 patients were included. The majority of the patients were female. The studies were methodologically poor. The primary outcome in all but one study was newly acquired infection defined as colony count >10(5)/ml in urine tested post UDS. On meta-analysis, there was 40% reduction in the risk of significant bacteriuria with administration of prophylactic antibiotics (Peto odds ratio 0.39; 95% confidence interval 0.24-0.61). The antibiotics used differed in dose, type and duration. One minor skin rash and one major anaphylactic reaction requiring steroid injection therapy was reported in the treatment group. One would need to give prophylactic antibiotics to 13 individuals undergoing UDS to prevent one significant bacteriuria of unknown clinical significance. CONCLUSION The use of prophylactic antibiotics in urodynamics reduces the risk of significant bacteriuria.

Abstract
PURPOSE The aim of this study was to review the experience of a single institution with the Deflux (Q-Med Scandinavia; Uppsala, Sweden) procedure and assess its effectiveness in reducing the incidence of urinary tract infections (UTIs) in children with vesicoureteric reflux (VUR). MATERIALS AND METHODS After institutional review board approval, the charts of 100 patients with VUR, who presented between June 2003 and June 2005, were prospectively reviewed. Data collected included: demographics, the number of preoperative and postoperative UTIs, a radiologic grade of VUR on a voiding cystourethrogram (VCUG) and the presence of VUR on a radionuclide VCUG 3 months after the procedure. Patients were continued on oral antibiotics until urine culture at 3 months was negative and no reflux was demonstrated on VCUG. The student's t test was used for data analysis. RESULTS The mean age was 3.8 +/- 0.3 years, and 76% were girls. From 155 ureters treated, 10 had Grade I reflux, 42 Grade II, 76 Grade III, 25 Grade IV, and 2 Grade V. A second injection was required in 22 ureters (14.2%). The overall success rate of the procedure (Grade 0 reflux at 3 months) was 77.4% after the first injection and 83.9% after a second injection. The success rate per grade was: 100% for Grade I, 88.1% for Grade II, 86.8% for Grade III, 64% for Grade IV, and 50% for Grade V. The mean follow-up was 446 +/- 20 days. The mean volume injected/ureter was 0.6 +/- 0.03 mL. Thirteen (13) patients had UTIs after the procedure, compared to 75 before. There was a 5-fold reduction in the incidence of UTIs/year, from a mean of 0.68 +/- 0.09 pre- to 0.12 +/- 0.04 postinjection (P = 0.001). The majority of UTIs were caused by Escherichia coli (74% pre- and 82% postinjection). CONCLUSIONS We conclude that the Deflux procedure is effective not only in eliminating VUR on radiologic studies, but also in reducing the incidence of UTIs and antibiotic use in children with VUR.

Abstract
OBJECTIVE This study characterizes further the behavior of serologically classified isolates of Escherichia coli in women with recurrent urinary tract infections (UTIs). METHODS A prospective, longitudinal study of 203 young to middle-aged women with UTIs was conducted. Seven hundred and sixty-one UTIs due to E. coli were identified in the 203 women during observation periods of 1.1-19.4 years. Isolates from urine were routinely serologically classified. Clusters of UTIs and rates per year of infections with the same serogroup were defined to quantify further UTIs. RESULTS One hundred and forty-eight (73%) of the 203 women experienced 2-42 UTIs with E. coli. Fifteen percent of recurrences occurred within 1 month of the previous infection; 57%, 6 months; and 70%, 1 year. During the first four months, recurrences with the same serogroup accounted for 81-50% of recurrences; thereafter, recurrences with a different serogroup were more frequent. Clusters of UTIs occurred in 52% of the 148 women and ranged in size from 2-5 infections. Multiple recurrences with the same serogroup were more frequently caused by a few common serogroups. CONCLUSIONS Isolates of a few common serogroups of E. coli were associated with the great majority of both index and recurrent UTIs. Some isolates of both common and less common serogroups were associated with multiple recurrences with the same serogroup. The wide range in rates/year among recurrences with isolates of different serogroups in individual women were consistent with the hypothesis that these differences were more likely to be due to differences in virulence of the isolates than to host factors.

Abstract
BACKGROUND AND PURPOSE The exact mechanism of fever and urosepsis after percutaneous procedures has not been established. This research studied the frequency of fever after percutaneous nephrolithotomy (PCNL) and the contributing factors. METHODS In a cross-sectional study, from September 2003 to March 2004, all 217 patients with nephrolithiasis treated with PCNL at the Labbafinegad Specialized Urology Center were studied. Data were collected before, during, and after surgery. RESULTS The frequency of fever after PCNL was 25.8% (n=56) although in 62.2% of the cases (n=135), no prophylactic antibiotics had been administered. The mean durations of hospitalization in patients with and without fever were 5.4+/-2.3 and 3.4+/-1.7 days, respectively (p=0.001). Significant correlations were observed between fever and female sex (p=0.005), positive urine culture (p=0.02), and nephrostomy tube insertion (p=0.041). Other variables did not prove to be significant. In logistic regression analysis, female sex and nephrostomy tube insertion were independently related to post-operative fever. CONCLUSION Although a considerable proportion of our patients had not received prophylactic antibiotics, the rate of fever after PCNL was no higher than is reported in the literature. Use of only a short course of antibiotics before surgery for staghorn stones did not result in a higher rate of fever. Female sex created a higher risk for fever, probably because of the greater propensity to urinary tract infection. The significant relation of a nephrostomy tube to fever could be attributed to its role as a foreign body or to use in more complicated cases.

Abstract
We report on the investigations and interventions conducted to contain an extended outbreak of Serratia marcescens bacteriuria that lasted for years in a neurosurgical intensive care unit (NSICU). A case-control study was performed to identify the risk factors for S. marcescens acquisition in urine. In case patients, urine sampling for tests and central venous catheterization were performed more frequently before the isolation of S. marcescens. Case patients were more frequently prescribed third-generation cephalosporins. Adherence to hand antisepsis was encouraged through in-service educational meetings and infection control measures, especially concerning the manipulation of indwelling urinary catheters, were intensified. The outbreak persisted despite the reinforcement of infection control measures. However, no patient has newly acquired the organism in the NSICU since December 2004. Multiple factors, including inadequate infection control practices and inappropriate antimicrobial usage, possibly contributed to the persistence of this S. marcescens outbreak. Healthcare workers should consistently follow infection control policies to ensure quality care.

Abstract
The purpose of the study was to evaluate whether antibiotic prophylaxis with a single dose of prulifloxacin after tension-free vaginal tape (TVT) procedure decreases catheter-associated urinary tract infections (UTIs). Patients undergoing TVT procedure receiving a single dose of prulifloxacin (600 mg) 10 h before catheter removal (n=54) were compared with historical controls who have had no treatment (n=60). All patients had an indwelling urethral catheter in situ for 24 h. Urine specimens for culture were collected preoperatively, before Foley removal, and 7 days postoperatively in both groups. Main outcome measures were significant bacteriuria and symptomatic UTI at catheter removal and 1 week postoperatively. No patient had a positive urine culture in the prulifloxacin group compared with 14 (23.3%) in the control group at catheter removal (P=0.0001). Ten out of 14 (71.4%) women with a positive catheter urine culture had a symptomatic UTI. One week after surgery no difference was found in the rate of significant bacteriuria between groups. Our data suggest that a prophylactic single dose of prulifloxacin could help to reduce the rate of symptomatic and asymptomatic UTIs after short-term urethral catheterization in women undergoing TVT procedure.

Abstract
BACKGROUND Although bladder drainage is widely used for general surgical patients undergoing laparotomy, there is little consensus on whether suprapubic or transurethral catheterization is better. METHOD A systematic database search was undertaken to find all studies of suprapubic catheterization. Randomized controlled trials were identified for inclusion. Endpoints for analysis were bacteriuria, patient satisfaction and recatheterization rates. A meta-analysis was performed using fixed-effect or random-effect models as appropriate, depending on heterogeneity. RESULTS After abdominal surgery, transurethral catheterization is associated with significant bacteriuria (relative risk (RR)=2.02, P<0.001, 95 percent confidence interval (c.i.) 1.34 to 3.04) and pain or discomfort (RR=2.94, P=0.004, 95 percent c.i. 1.41 to 6.14). Recatheterization rates using the transurethral method were not increased significantly (RR=1.97, P=0.213, 95 percent c.i. 0.68 to 5.74) with heterogeneity between studies. CONCLUSION The suprapubic route for bladder drainage in general surgery is more acceptable to patients and reduces microbiological morbidity.

Abstract
(1) Female urinary tract infections are common and often recurrent. Food supplements based on cranberries are said to prevent recurrent urinary tract infections. (2) Two randomised controlled trials involving a total of about 300 young women showed that daily use of cranberry juice or tablets reduced the relapse rate for acute cystitis: on average, treating 100 women for one year prevented at least 1 urinary tract infection in 15 to 33 women. The daily doses were 7.5 g of concentrate in 50 ml of water, 750 ml of juice, or two tablets of concentrate. (3) In elderly patients, 2 trials of cranberry-based products in hospitals or nursing homes showed a small reduction in the frequency of relapses. (4) Adverse effects appear to be negligible. However, several case reports of interactions with warfarin have been published, including one involving severe bleeding. Patients on vitamin K antagonists must be warned about this risk of interactions so that they avoid consuming cranberry-based products without medical supervision.

Abstract
OBJECTIVES To compare condom and indwelling urinary catheters in terms of infection risk and patient satisfaction. DESIGN A prospective, randomized, unblinded, controlled trial. SETTING An academically affiliated Veterans Affairs Medical Center. PARTICIPANTS Hospitalized men aged 40 and older who required a urinary collection device. MEASUREMENTS The incidence of adverse outcomes (bacteriuria, symptomatic urinary tract infection (UTI), or death) and patient device-related satisfaction as determined according to a questionnaire. Dementia status was recorded to assess effect modification by the presence of dementia. RESULTS Seventy-five subjects were randomized: 41 receiving an indwelling catheter and 34 a condom catheter. The incidence of an adverse outcome was 131/1,000 patient-days with an indwelling catheter and 70/1,000 patient-days with a condom catheter (P=.07). The median time to an adverse event was 7 days in the indwelling group and 11 days in the condom group. After adjusting for other risk factors, it was found that condom catheter use reduced adverse outcomes (P=.04). Patients without dementia who had an indwelling catheter were approximately five times as likely to develop bacteriuria or symptomatic UTI or to die (hazard ratio=4.84, 95% confidence interval=1.46-16.02) as those with a condom catheter (P=.01). Patients reported that condom catheters were more comfortable (P=.02) and less painful (P=.02) than indwelling catheters. CONCLUSION The use of condom catheters is less likely to lead to bacteriuria, symptomatic UTI, or death than the use of indwelling catheters. This protection is especially apparent in men without dementia.

Abstract
OBJECTIVES To determine the efficacy of prophylactic ciprofloxacin in preventing urinary tract infections caused by urodynamic study (UDS). METHODS A total of 210 patients presenting for UDS during a 16-month period were offered enrollment in the study. A clean-catch midstream urine sample was taken 24 hours before and 48 to 72 hours after the procedure and after microscopic examination and culture were done. All patients underwent a standard UDS. The 192 patients who had sterile urine before intervention were included in the study. Randomly, 98 of the 192 patients were orally given 500 mg of ciprofloxacin 1 hour before the urodynamic intervention and 94 were not given anything. The patients who were found to have significant bacteriuria after UDS were followed up and treated properly. RESULTS Eighteen patients (8.6%) who had significant bacteriuria in the urine culture before UDS were excluded from the study. The rate of significant bacteriuria in the urine culture after UDS was 7.3% overall, 1% in the prophylaxis group, and 14% in the controls, a significant difference (P = 0.002). The most common uropathogen was Escherichia coli (57%). Three independent risk factors were identified: not giving antibiotic prophylaxis before UDS; antibiotic use in the preceding month; and the presence of pyuria before UDS. CONCLUSIONS Urinary tract infections after UDS decreased from 14% to 1% with a single dose of ciprofloxacin 500 mg orally before UDS. We recommend antibiotic prophylaxis for patients undergoing a UDS.

Abstract
Urinary tract infections (UTI) are among the most frequent bacterial infections in women. Mostly young women and, to some extent, postmenopausal women are affected by recurrent UTI (rUTI), defined as >or=3 UTI/year. Modifiable predisposing factors are rare. The differential diagnosis between relapse and reinfection is decisive for therapy. Antibiotic prophylaxis has emerged as one of the most important therapeutic principles in rUTI. Depending on the drug utilized, the various modes of action are described as reducing the number of uropathogens in the gut and vaginal flora and/or in repeatedly eliminating bacteria from the urine. According to the European Association of Urology guidelines, nitrofurantoin, trimethoprim, and cotrimoxazole are available as first-line drugs. Cephalexin and the quinolones should be restricted to specific indications. Depending on the case, long-term antibiotic prophylaxis for 6 months, postcoital single dose prophylaxis, or patient-initiated self-start therapy can all be used successfully. Given the correct indications, the recurrence rate of rUTI can be reduced by 95%.

Abstract
BACKGROUND The efficacy of antimicrobial urinary catheters in hospitalized patients is poorly defined. PURPOSE To assess currently marketed antimicrobial urinary catheters for preventing catheter-associated urinary tract infection (UTI). DATA SOURCES Electronic databases, conference proceedings, bibliographies, trialists, and catheter manufacturers (search dates, 1966 to June 2005). STUDY SELECTION Randomized and quasi-randomized trials of nitrofurazone-coated or silver alloy-coated antimicrobial urinary catheter use for less than 30 days; no language restriction. DATA EXTRACTION Study design, study sample, inclusion and exclusion criteria, allocation, blinding, UTI definition, ascertainment methods, and proportion developing symptomatic UTI (primary end point) or bacteriuria (secondary end point) were extracted by using a structured data collection instrument. DATA SYNTHESIS Twelve qualifying trials (13,392 total participants or catheters) were identified. They compared nitrofurazone-coated silicone (n = 3) or silver-coated latex (n = 9) catheters with silicone or latex catheters. No study addressed symptomatic UTI. All trials suggested protection against bacteriuria with test catheter use. However, effect size varied considerably and postrandomization exclusions were very common. Effect size was greatest in trials of nitrofurazone-coated catheters (all post-1995) and in pre-1995 silver alloy-coated catheter trials and was smallest in post-1995 silver alloy-coated catheter trials. Control group bacteriuria rate, control catheter type (latex vs. silicone), and patient sample (urology vs. other) also predicted effect size. Few studies addressed secondary bloodstream infection, mortality, costs, or microbial resistance. Short-term adverse effects were minimal. LIMITATIONS The study was limited by the number, size, and quality of studies and by lack of the following: intention-to-treat analyses, data on clinical end points, and trials comparing nitrofurazone-coated with silver alloy-coated catheters. CONCLUSIONS According to fair-quality evidence, antimicrobial urinary catheters can prevent bacteriuria in hospitalized patients during short-term catheterization, depending on antimicrobial coating and several other variables. Older data probably lack current relevance. Cost implications and effect on infectious complications remain undefined.
