RESUMO
BACKGROUND: Double J ureteral stents are widely used on urological patients to provide drainage of the upper urinary tract. Unfourtunately, ureteral stents are not free from complications, as bacterial colonization and require a second procedure for removal. The purpose of the current comparative experimental study is to evaluate a new heparin-coated biodegradable antireflux ureteral stent (BraidStent®-H) to prevent urinary bacterial colonization. METHODS: A total of 24 female pigs were underwent determination of bacteriuria and nephrosonographic, endoscopic and contrast fluoroscopy assessment of the urinary tract. Afterward, were randomly assigned animals to Group-I, in which a 5Fr double-pigtail ureteral stent was placed for 6 weeks, or Group-II, in which a BraidStent®-H was placed. Follow-up assessments were performed at 1, 3, 6, 8, 12 weeks. The final follow-up includes the above methods and an exhaustive pathological study of the urinary tract was accomplished after 20 weeks. RESULTS: Bacteriuria findings in the first 48 h were significant between groups at 6 h and 12 h. Asymptomatic bacteriuria does not reach 100% of the animals in Group-II until 48 h versus Group-I where it appears at 6 h. The weekly bacteriuria mean rate was 27.7% and 44.4% in Group I and II respectively, without statistical significance. In Group II there were no animals with vesicoureteral reflux, with statistical significance at 3 and 6 weeks with Group-I. The 91.2% of stents in Group-II were degraded between 3 and 6 weeks, without obstructive fragments. Distal ureteral peristalsis was maintained in 66.6-75% in Group-II at 1-6 weeks. CONCLUSIONS: The heparin coating of BraidStent® allows an early decrease of bacterial colonization, but its effectiveness is low at the long term. Heparin coating did not affect scheduled degradation rate or size of stents fragments. BraidStent®-H avoids the side effects associated with current ureteral stents, thus should cause less discomfort to patients.

PURPOSE: To compare efficacy, safety, and cost-effectiveness of fosfomycin tromethamine with other standard-of-care antibiotics in patients undergoing ureteroscopic lithotripsy. METHODS: This study was a prospective, multicenter, randomized, controlled trial. Eligible patients scheduled for ureteroscopic lithotripsy were randomly assigned to receive either fosfomycin (fosfomycin group, N = 101 patients) or standard-of-care antibiotic therapy as prophylaxis (control group, N = 115 patients). The incidence of infectious complications and adverse events was analyzed between the two groups, as well as the cost-benefit analysis. RESULTS: The incidence of infections following lithotripsy was 3.0% in the fosfomycin group and 6.1% in the control group (p > 0.05). Only asymptomatic bacteriuria was reported in fosfomycin group. In the control group was reported asymptomatic bacteriuria (3.5%), fever (0.9%), bacteremia (0.9%), and genitourinary infection (0.9%). The rate of adverse events was very low, with no adverse event reported in the fosfomycin group and only one in the control group (forearm phlebitis). The average cost per patient of antibiotic therapy with fosfomycin was 151.45 ± 8.62 yuan (22.7 ± 1.3 USD), significantly lower compared to the average cost per patient of antibiotics used in the control group 305.10 ± 245.95 yuan (45.7 ± 36.9 USD; p < 0.001). CONCLUSIONS: Two oral doses of 3 g fosfomycin tromethamine showed good efficacy and safety and low cost in perioperative prophylaxis of infections following ureteroscopic stone removal.

BACKGROUND: Update of the 2010 published evidence-based S3 guideline on epidemiology, diagnostics, therapy and management of uncomplicated, bacterial, outpatient-acquired urinary tract infections in adult patients. The guideline contains current evidence for the rational use of antimicrobial substances, avoidance of inappropriate use of certain antibiotic classes and development of resistance. METHODOLOGY: The update was created under the leadership of the German Association of Urology (DGU). A systematic literature search was conducted for the period 01 January 2008 to 31 December 2015. International guidelines have also been taken into account. Evidence level and risk of bias were used for quality review. RESULTS: Updated information on bacterial susceptibility, success, collateral damage and safety of first- and second-line antibiotics was given. For the treatment of uncomplicated cystitis the first line antibiotics are fosfomycin trometamol, nitrofurantoin, nitroxoline, pivmecillinam, trimethoprim (with consideration of the local resistance rates). Fluoroquinolones and cephalosporins should not be used as first choice antibiotics. In the case of uncomplicated pyelonephritis of mild to moderate forms, preferably cefpodoxime, ceftibuten, ciprofloxacin or levofloxacin should be used as oral antibiotics. CONCLUSION: The updated German S3 guideline provides comprehensive evidence- and consensus-based recommendations on epidemiology, diagnostics, therapy, prevention and management of uncomplicated bacterial outpatient acquired urinary tract infections in adult patients. Antibiotic stewardship aspects have significantly influenced the therapeutic recommendations. A broad implementation in all clinical practice settings is necessary to ensure a foresighted antibiotic policy and thus t improve clinical care.

OBJECTIVE: The objective of this study was to compare the safety, efficacy, quality-of-life impact, and costs of a single dose or a longer course of pre-procedural antibiotics prior to elective endoscopic urological procedures in individuals with spinal cord injury and disorders (SCI/D) and asymptomatic bacteriuria. DESIGN: A prospective observational study. SETTING: Hunter Holmes McGuire Veterans Affairs Medical Center, Richmond, Virginia, USA. PARTICIPANTS: Sixty persons with SCI/D and asymptomatic bacteriuria scheduled to undergo elective endoscopic urological procedures. INTERVENTIONS: A single pre-procedural dose of antibiotics vs. a 3-5-day course of pre-procedural antibiotics. OUTCOME MEASURES: Objective and subjective measures of health, costs, and quality of life. RESULTS: There were no significant differences in vital signs, leukocytosis, adverse events, and overall satisfaction in individuals who received short-course vs. long-course antibiotics. There was a significant decrease in antibiotic cost (33.1 ± 47.6 vs. 3.6 ± 6.1 US$, P = 0.01) for individuals in the short-course group. In addition, there was greater pre-procedural anxiety (18 vs. 0%, P < 0.05) for individuals who received long-course antibiotics. CONCLUSION: SCI/D individuals with asymptomatic bacteriuria may be able to safely undergo most endoscopic urological procedures with a single dose of pre-procedural antibiotics. However, further research is required and even appropriate pre-procedural antibiotics may not prevent severe infections.

Catheter-associated urinary tract infection is the most common nosocomial infection, with hospitalized patients having a risk of 5% per day an indwelling catheter is in place. Use of catheters coated with silver alloy-hydrogel significantly reduces the risk of catheter-associated urinary tract infection and the burden on the NHS.

OBJECTIVE: Little is known regarding the prevalence of early postpartum bacteriuria. We sought to evaluate the incidence of bacteriuria following labor and to identify risk factors predisposing to this condition. METHODS: Three hundred and fifty parturients were recruited, 301 were included in the analysis. Women receiving antibiotic drugs during delivery were excluded. Urine cultures were obtained from the study group before delivery and prior to discharge. Data regarding management of labor was collected prospectively. RESULTS: Positive urine cultures were present on admission in 5.4% of women, whereas 12.9% had a positive urine culture at discharge (p < 0.003). Bacteriuria was acquired during labor in 12.7% of patients who had negative cultures on admission. Escalating number of digital vaginal examinations (p = 0.04), recurrent bladder catheterization (p = 0.05), duration of epidural anesthesia (p = 0.002), and vacuum delivery (p = 0.02) correlated significantly with an increased risk for acquiring bacteriuria. CONCLUSION: Labor is a bacteriuric event. Iatrogenic interventions can predispose parturients with sterile urine cultures to postpartum bacteriuria.

OBJECTIVE: In a previous nonrandomized study we observed no difference in the rate of acquisition of bacteriuria between a complex closed drainage system (CCDS) and a two-chamber drainage system (TCDS) in ICU patients. To confirm this result we performed a statistically powerful study assessing the effectiveness of the CCDS and the TCDS in ICU patients. DESIGN AND SETTING: Randomized, prospective, and controlled study in the medicosurgical intensive care unit (16 beds) in a teaching hospital. PATIENTS AND INTERVENTIONS: We assigned 311 patients requiring indwelling urinary catheter for longer than 48 h to TCDS or CCDS to compare the rate of acquisition of bacteriuria. MEASUREMENTS AND RESULTS: Patients did not receive prophylactic antibiotics during placement management or catheter withdrawal. Urine samples were obtained weekly for the duration of catheterization and within 24 h after catheter removal, and each time symptoms of urinary infection were suspected. There was no statistical difference in the rate of bacteriuria between the two groups: 8% with TCDS and 8.5% with CCDS. Rates of urinary tract infection were 12.1 episodes with TCDS and 12.8 episodes with CCDS per 1000 days of catheter. CONCLUSIONS: This randomized study on the effectiveness of TCDS and CCDS in ICU patients confirms the findings of our previous study. No differences were noted between the two systems. The higher cost of CCDS is not justified for ICU patients.

DESIGN: Randomized, prospective, and controlled study. SETTING: Medico-surgical intensive care unit (16 beds) in a teaching hospital. PATIENTS AND INTERVENTIONS: Three hundred and eleven patients requiring an indwelling urinary catheter for longer than 48 h were assigned individuals to the TCDS group or CCDS group to compare the rate of acquisition of bacteriuria. MEASUREMENTS AND RESULTS: Patients did not receive prophylactic antibiotics during placement management or catheter withdrawal. Urine samples were obtained weekly for the duration of catheterization and within 24 h after catheter removal, and each time symptoms of urinary infection were suspected. There was no statistical difference in the rate of bacteriuria between the two groups. Bacteriuria occurred in 8% and 8.5% of patients for TCDS and CCDS, respectively. Rates of urinary tract infection were 12.1 and 12.8 episodes per 1,000 days of catheter. CONCLUSION: This randomized study, that compares the effectiveness of a TCDS and a CCDS in ICU patients, confirms the results of our previous study. No differences were noted between the two systems (a =0.05). The higher cost of CCDS is not justified for ICU patients.

Urinary tract infections requiring treatment are extremely common. It is estimated that between 20 and 50% of adult women will have had at least one symptomatic urinary tract infection. When considering the optimal therapy of any infection, patient factors, organism factors, drug factors (e.g. pharmacokinetics), side-effects and cost as well as antimicrobial resistance all need to be considered. This paper deals with the impact of increasing antibiotic resistance on the management of urinary tract infections.

An open prospective study was carried out in 82 consecutive patients undergoing resective surgery for esophageal cancer from January 1995 to July 1996. Antimicrobial prophylaxis was done using a single dose of ceftriaxone (2 g i.v.) given at the induction of anesthesia in combination with metronidazole (0.5 g i.v.). Two further doses of metronidazole were administered 8 and 16 hours postoperatively. Fourteen patients (17%) experienced postoperative infections. This study, even though open and non-comparative, confirms that ceftriaxone given as a single-dose plus metronidazole provides adequate prophylaxis and significant cost-savings in comparison with multiple-dose prophylactic regimens in patients undergoing major surgery for esophageal cancer. Furthermore, the single-dose regimen reduces the workload for the nursing staff, the risk of side effects, and the possibility of selecting resistant strains.

Measures of decision sensitivity that have been applied to medical decision problems were examined. Traditional threshold proximity methods have recently been supplemented by probabilistic sensitivity analysis, and by entropy-based measures of sensitivity. The authors propose a fourth measure based upon the expected value of perfect information (EVPI), which they believe superior both methodologically and pragmatically. Both the traditional and the newly suggested sensitivity measures focus entirely on the likelihood of decision change without attention to corresponding changes in payoff, which are often small. Consequently, these measures can dramatically overstate problem sensitivity. EVPI, on the other hand, incorporates both the probability of a decision change and the marginal benefit of such a change into a single measure, and therefore provides a superior picture of problem sensitivity. To lend support to this contention, the authors revisit three problems from the literature and compare the results of sensitivity analyses using probabilistic, entropy-based, and EVPI-based measures.

OBJECTIVES: To compare the safety and cost of clean versus sterile intermittent bladder catheterization in male nursing home residents. To provide evidence to support the hypothesis that intermittent catheterization is a valid, alternative method of bladder management in male residents of long-term care in whom urinary retention is a documented problem. DESIGN: Randomized clinical trial. SETTING: Three long-term care sites having predominantly male populations. PARTICIPANTS: Eighty male veterans, residents of three long-term care facilities, ranging in age from 36 to 96 years with a mean age of 72. INTERVENTIONS: Standardized procedures for clean and sterile intermittent catheterization (IC) were implemented by staff nurses at each site. Patients were randomized into clean and sterile IC groups. Nursing time and catheterization equipment usage were recorded using bar code readers. Clinical data were collected from the medical chart. Treatment of urinary tract infection was prescribed by the medical personnel responsible for each individual resident. MEASUREMENTS: We compared the number of treatment episodes for symptomatic bacteriuria between groups randomized to receive either clean or sterile intermittent catheterization. Laboratory analysis of blood and urine was done on predetermined days. Control variables were research site and patient history of urinary tract infection within the last 6 months. A cost comparison of nursing time and equipment usage for the two catheterization techniques was also performed. RESULTS: No significant differences were found between clean and sterile groups with regard to number of treatment episodes, time to first infection, type of organism cultured, or cost of antibiotic treatment. The cost of sterile technique was considerably higher both in terms of nursing time and supplies. CONCLUSIONS: Findings from this study demonstrate that clean technique intermittent catheterization is a safe and cost-effective bladder management technique with male, nursing home residents, despite the frailty of this high risk population. An annual savings of approximately $1460 per patient in nursing time and catheterization supplies could be anticipated if a patient were catheterized an average of four times per day substituting clean IC technique for sterile IC technique.

The prevalence and socio-biological relations of bacteriuria in Trinidadian pregnant women were investigated. The prevalence of bacteriuria was found to be 16.7% and it was more common in the 30-39 year age group, among parous women, among Negroes, and in patients with a low family income and overcrowded living conditions. Symptoms were present in 19% of bacteriuric patients and almost one-third gave a past history of urinary tract infection. Only 10% had been previously exposed to sexually transmitted diseases such as syphilis, gonorrhea and herpetic genital infections. Because of the serious consequences to mother and foetus, we advocate quantitative urine cultures for all antenatal patients, especially those coming from disadvantaged socio-economic conditions.

The antibacterial activity of six antiseptic solutions formulated for use in bladder washout procedures has been examined in a simple model of the catheterized bladder. The experiments were carried out under conditions which examined the efficacy of the formulations against organisms that had recently contaminated the bladder urine. At cell densities of 10(4) cfu ml-1 all the solutions tested proved effective in eliminating bacteria from the bladder urine. Under conditions simulating heavy contamination (10(7)-10(8) cfu ml-1) however, only mandelic acid (1% w/v) eliminated the range of bacterial species commonly responsible for catheter-associated urinary tract infection.

We used a standard microwave oven to sterilize red rubber catheters used for intermittent self-catheterization. Catheters were incubated for sixty minutes in a suspension of microorganisms isolated from the urine of patients with urinary tract infections. For each trial, 6 catheters were removed from their respective suspensions, placed in separate plastic freezer bags, distributed evenly in a microwave oven (avoiding cold spots), and microwaved simultaneously for twelve minutes. A control catheter was not microwaved. Two strains of each microorganism were tested. The urinary isolates were Escherichia coli, Klebsiella sp., Proteus sp., Enterobacter sp., Pseudomonas sp., Streptococcus sp., Staphylococcus sp., and Candida sp. In each experiment, all 6 catheters were sterilized. Repeat sterilization in the microwave oven did not affect the integrity of the catheters or the plastic bags. A water heat sink of constant volume was employed. A home microwave oven may be used as a method to sterilize red rubber catheters for reuse with a recommended time of twelve minutes at full power. This technique makes aseptic intermittent self-catheterization a practical possibility.

Patients with neurologic injuries frequently have permanent indwelling or external catheters connected to disposable urinary bags. These patients routinely disconnect the bed bag during the day and apply a leg bag which can be concealed under their clothes. In our rehabilitation unit, both bags are discarded daily. This study investigated the possibility of safely reusing bed and leg bags. The procedure involved decontamination of the bags using 180 ml of a 1% solution of sodium hypochlorite. Initially, discarded bed and leg bags were decontaminated in the lab to ensure effectiveness of the procedure. Next, 22 patients reused their bed and leg bags with daily decontamination by the rehabilitation nursing staff. These bags were reused for two to eight days. Cultures of 137 bags were obtained to evaluate the technique. All cultures were negative. Baseline urine cultures for both time periods showed no significant difference in rates of bacteriuria. The potential savings for one year on our rehabilitation unit, with an average of 12 catheterized patients, would be approximately $39,000. Although this methodology conflicts with thoughts about not reusing disposable products, we have shown that the procedure can be done safely in rehabilitation patients and it is easy and inexpensive.
