    Full Text Available Lower urinary tract infections are very common diseases. Recurrent urinary tract infections remain challenging to treat because the main treatment option is long-term antibiotic prophylaxis; however, this poses a risk for the emergence of bacterial resistance. Some options to avoid this risk are available, including the use of cranberry products. This article reviews the key methods in using cranberries as a preventive measure for lower urinary tract infections, including in vitro studies and clinical trials.

    Full Text Available BACKGROUND: Cranberries have been used widely for several decades for the prevention and treatment of urinary tract infections (UTIs. This is the third update of our review first published in 1998 and updated in 2004 and 2008. OBJECTIVES: To assess the effectiveness of cranberry products in preventing UTIs in susceptible populations. METHODS: Search methods: We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL in The Cochrane Library and the Internet. We contacted companies involved with the promotion and distribution of cranberry preparations and checked reference lists of review articles and relevant studies. Date of search: July 2012. Selection criteria: All randomised controlled trials (RCTs or quasi-RCTs of cranberry products for the prevention of UTIs. Data collection and analysis: Two authors independently assessed and extracted data. Information was collected on methods, participants, interventions and outcomes (incidence of symptomatic UTIs, positive culture results, side effects, adherence to therapy. Risk ratios (RR were calculated where appropriate, otherwise a narrative synthesis was undertaken. Quality was assessed using the Cochrane risk of bias assessment tool. MAIN RESULTS: This updated review includes a total of 24 studies (six cross-over studies, 11 parallel group studies with two arms; five with three arms, and two studies with a factorial design with a total of 4473 participants. Ten studies were included in the 2008 update, and 14 studies have been added to this update. Thirteen studies (2380 participants evaluated only cranberry juice/concentrate; nine studies (1032 participants evaluated only cranberry tablets/capsules; one study compared cranberry juice and tablets; and one study compared cranberry capsules and tablets. The comparison/control arms were placebo, no treatment, water, methenamine hippurate, antibiotics, or lactobacillus. Eleven studies were not included in the meta

    Urinary tract infection (UTI) in females occurs significantly more frequently than in males because of specific anatomical and functional features of female urinary system, sequelae of pregnancy, delivery, gynecological diseases. Much controversy still exists as to pathogenesis of UTI and UTI-induced urinary inflammation. We have examined 233 females of different age with UTI and obtained evidence which shows participation of such factors as early and intensive sex, ignorance of sex hygiene, multiple pregnancies, deliveries, abortions, inflammatory gynecological diseases, anogenital infection in its pathogenesis. These factors were registered 2-4 times more frequently in UTI females than in controls without UTI. Bacteriological urinary and genital findings coincide in 80% of cases in terms of an infective agent. This suggests that it is essential to detect urogenital infection in girls and females as early as possible and to treat it adequately with antibacterial and other drugs. The leading role of an ascending urinogenic route in urinary tract infection from local sources in anogenital zone, sexual factor and the absence of relevant hygienic habits proved most contributing to UTI pathogenesis. This concept serves the basis for UTI prevention in females.

    Recurrent urinary tract infection (RUTI) is defined as three episodes of urinary tract infection (UTI) in the previous 12 months or two episodes in the last six months. The main factors associated with RUTI in postmenopausal women are vesical prolapse, cystocoele, post-voidal residue and urinary incontinence, all associated with a decrease in oestrogen. The use of oestrogens to prevent RUTI has been proposed. To estimate the efficacy and safety of oral or vaginal oestrogens for preventing RUTI in postmenopausal women. We searched the Cochrane Renal Group's specialised register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (from 1950), EMBASE (from 1980), reference lists of articles without language restriction. Date of last search: February 2007. Randomised controlled trials (RCTs) in which postmenopausal women (more than 12 months since last menstrual period) diagnosed with RUTI received any type of oestrogen (oral , vaginal) versus placebo or any other intervention were included. Authors extracted data and assessed quality. Statistical analyses were performed using the random effects model and the results expressed as relative risk (RR) for dichotomous outcomes or mean difference (WMD) for continuous data with 95% confidence intervals (CI). Nine studies (3345 women) were included. Oral oestrogens did not reduce UTI compared to placebo (4 studies, 2798 women: RR 1.08, 95% CI 0.88 to 1.33). Vaginal oestrogens versus placebo reduced the number of women with UTIs in two small studies using different application methods. The RR for one was 0.25 (95% CI 0.13 to 0.50) and 0.64 (95% CI 0.47 to 0.86) in the second. Two studies compared oral antibiotics versus vaginal oestrogens (cream (1), pessaries (1)). There was very significant heterogeneity and the results could not be pooled. Vaginal cream reduced the proportion of UTIs compared to antibiotics in one study and in the second study antibiotics were superior to vaginal pessaries. Adverse events

    Urinary tract infection (UTI) is the most common infection in patients with spinal cord injury (SCI) and is a major cause of morbidity and mortality in this population. The bladders of patients with SCI, particularly those with indwelling bladder catheters, can become colonized by a variety of organisms, including those that may, and others that may not, cause symptoms of infection. The latter group of bacteria, so-called benign colonizers, are often left untreated because they may provide some protection against symptomatic infection with more pathogenic bacteria. In recent years, deliberate urogenital tract colonization with benign bacterial strains was studied with the objective of offering some protection against invasion by uropathogenic strains. When well-characterized strains of Lactobacillus sp. were used to colonize the vagina of women prone to frequent UTI, a moderate reduction in the rate of recurrent UTI was observed. In other studies, a non-pathogenic prototype of Escherichia coli (strain 83,972) causing asymptomatic bacteriuria was used for deliberate bladder colonization. These preliminary observations encourage the examination of the safety and preventive efficacy of this approach in human subjects.

    2016-12-01

    Full Text Available A complicated urinary tract infection (UTI has relapsing and refractory characteristics, and is sometimes life-threatening because of patient predisposing factors as well as the recent worldwide spread of multi-drug resistant bacteria. Patients with complicated UTI should be treated with effective antimicrobial therapy along with appropriate urological intervention to remove predisposing factors when the symptoms are associated. By contrast, routine use of antimicrobial prophylaxis for asymptomatic bacteriuria (ASB is not recommended, as that would contribute to an increase in even more resistant pathogens. Here, four classifications of complicated UTI, which are considered to be clinically important for general urologists, are reviewed, including UTI in patients with diabetes mellitus (DM and those with a neurogenic bladder, as well as catheter-associated UTI (CAUTI and obstructive pyelonephritis secondary to urolithiasis. Appropriate treatment approaches can only be chosen by proper understanding of the etiologies of complicated UTI, as well as correct diagnostic strategies and treatment options.

    Urinary catheters are widely used for hospitalized patients and are often associated with high rates of urinary tract infection. We evaluated in vitro the antiadherence activity of a novel antiseptic Gendine-coated urinary catheter against several multidrug-resistant bacteria. Gendine-coated urinary catheters were compared to silver hydrogel-coated Foley catheters and uncoated catheters. Bacterial biofilm formation was assessed by quantitative culture and scanning electron microscopy. These data were further correlated to an in vivo rabbit model. We challenged 31 rabbits daily for 4 days by inoculating the urethral meatus with 1.0 × 109 CFU streptomycin-resistant Escherichia coli per day. In vitro, Gendine-coated urinary catheters reduced the CFU of all organisms tested for biofilm adherence compared with uncoated and silver hydrogel-coated catheters (P < 0.004). Scanning electron microscopy analysis showed that a thick biofilm overlaid the control catheter and the silver hydrogel-coated catheters but not the Gendine-coated urinary catheter. Similar results were found with the rabbit model. Bacteriuria was present in 60% of rabbits with uncoated catheters and 71% of those with silver hydrogel-coated catheters (P < 0.01) but not in those with Gendine-coated urinary catheters. No rabbits with Gendine-coated urinary catheters had invasive bladder infections. Histopathologic assessment revealed no differences in toxicity or staining. Gendine-coated urinary catheters were more efficacious in preventing catheter-associated colonization and urinary tract infections than were silver hydrogel-coated Foley catheters and uncoated catheters.

    Catheter-associated urinary tract infection (CAUTI) represents one of the most common causes of morbidity and mortality. The resistance demonstrated by many microorganisms to conventional antibiotic therapies and the increasing health-care costs have recently encouraged the definition of alternative preventive strategies, which can have a positive effect in the management of infections. Antimicrobial urinary catheters have been developed through the photo-chemical deposition of silver coatings on the external and luminal surfaces. The substrates are exposed to ultraviolet radiation after impregnation into a silver-based solution, thus inducing the in situ synthesis of silver particles. The effect of the surface treatment on the material was investigated through scanning electron microscopy (SEM) and silver ion release measurements. The ability of microorganisms commonly associated with urinary tract infections was investigated in terms of bacterial viability, proliferation and biofilm development, using Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis as target organisms. The silver coatings demonstrated good distribution of silver particles to the substrate, and proved an effective antibacterial capability in simulated biological conditions. The low values of silver ion release demonstrated the optimum adhesion of the coating. The results indicated a good potential of silver-based antimicrobial materials for prevention of catheter-associated urinary tract infection. - Highlights: • Silver nanocoatings were deposited on urinary catheters. • Both luminal and outer surface were successfully treated. • The treated devices demonstrated were effective against different microorganisms. • The antibacterial potential of the devices was assessed.

    Urinary tract infections (UTI) are among the most common bacterial infections in humans, affecting millions of people every year. UTI cause significant morbidity in women throughout their lifespan, in infant boys, in older men, in individuals with underlying urinary tract abnormalities, and in those that require long-term urethral catheterization, such as patients with spinal cord injuries or incapacitated individuals living in nursing homes. Serious sequelae include frequent recurrences, pyelonephritis with sepsis, renal damage in young children, pre-term birth, and complications of frequent antimicrobial use including high-level antibiotic resistance and Clostridium difficile colitis. Uropathogenic E. coli (UPEC) cause the vast majority of UTI, but less common pathogens such as Enterococcus faecalis and other enterococci frequently take advantage of an abnormal or catheterized urinary tract to cause opportunistic infections. While antibiotic therapy has historically been very successful in controlling UTI, the high rate of recurrence remains a major problem, and many individuals suffer from chronically recurring UTI, requiring long-term prophylactic antibiotic regimens to prevent recurrent UTI. Furthermore, the global emergence of multi-drug resistant UPEC in the past ten years spotlights the need for alternative therapeutic and preventative strategies to combat UTI, including anti-infective drug therapies and vaccines. In this chapter, we review recent advances in the field of UTI pathogenesis, with an emphasis on the identification of promising drug and vaccine targets. We then discuss the development of new UTI drugs and vaccines, highlighting the challenges these approaches face and the need for a greater understanding of urinary tract mucosal immunity.

    Urinary tract infection and asymptomatic bacteriuria are common in older adults. Unlike in younger adults, distinguishing symptomatic urinary tract infection from asymptomatic bacteriuria is problematic, as older adults, particularly those living in long-term care facilities, are less likely to present with localized genitourinary symptoms. Consensus guidelines have been published to assist clinicians with diagnosis and treatment of urinary tract infection; however, a single evidence-based approach to diagnosis of urinary tract infection does not exist. In the absence of a gold standard definition of urinary tract infection that clinicians agree upon, overtreatment with antibiotics for suspected urinary tract infection remains a significant problem, and leads to a variety of negative consequences including the development of multidrug-resistant organisms. Future studies improving the diagnostic accuracy of urinary tract infections are needed. This review will cover the prevalence, diagnosis and diagnostic challenges, management, and prevention of urinary tract infection and asymptomatic bacteriuria in older adults.

    Recurrent urinary tract infections (UTIs) are common, especially in women. Low-dose daily or postcoital antimicrobial prophylaxis is effective for prevention of recurrent UTIs and women can self-diagnose and self-treat a new UTI with antibiotics. The increasing resistance rates of Escherichia coli to antimicrobial agents has, however, stimulated interest in nonantibiotic methods for the prevention of UTIs. This article reviews the literature on efficacy of different forms of nonantibiotic prophylaxis. Future studies with lactobacilli strains (oral and vaginal) and the oral immunostimulant OM-89 are warranted. Copyright © 2014 Elsevier Inc. All rights reserved.

    Urinary tract infections are one of the most common bacterial infections, especially in women and children, frequently treated with antibiotics. The alarming increase in antibiotic resistance is a global threat to future treatment of infections. Therefore, alternative strategies are urgently needed. The innate immune system plays a fundamental role in protecting the urinary tract from infections. Antimicrobial peptides form an important part of the innate immunity. They are produced by epithelial cells and neutrophils and defend the urinary tract against invading bacteria. Since efficient resistance mechanisms have not evolved among bacterial pathogens, much effort has been put into exploring the role of antimicrobial peptides and possibilities to utilize them in clinical practice. Here, we describe the impact of antimicrobial peptides in the urinary tract and ways to enhance the production by hormones like vitamin D and estrogen. We also discuss the potential of medicinal herbs to be used in the prophylaxis and the treatment of urinary tract infections. PMID:26828523

    Objective To determine whether recurrences of urinary tract infection can be prevented with cranberry-lingonberry juice or with Lactobacillus GG drink. Design Open, randomised controlled 12 month follow up trial. Setting Health centres for university students and staff of university hospital. Participants 150 women with urinary tract infection caused by Escherichia coli randomly allocated into three groups. Interventions 50 ml of cranberry-lingonberry juice concentrate daily for six months or 100 ml of lactobacillus drink five days a week for one year, or no intervention. Main outcome measure First recurrence of symptomatic urinary tract infection, defined as bacterial growth ⩾105 colony forming units/ml in a clean voided midstream urine specimen. Results The cumulative rate of first recurrence of urinary tract infection during the 12 month follow up differed significantly between the groups (P=0.048). At six months, eight (16%) women in the cranberry group, 19 (39%) in the lactobacillus group, and 18 (36%) in the control group had had at least one recurrence. This is a 20% reduction in absolute risk in the cranberry group compared with the control group (95% confidence interval 3% to 36%, P=0.023, number needed to treat=5, 95% confidence interval 3 to 34). Conclusion Regular drinking of cranberry juice but not lactobacillus seems to reduce the recurrence of urinary tract infection. What is already known on this topicUp to 60% of women will have a urinary tract infection and a third of them will have several recurrencesVaccinium berries and products containing lactobacilli may affect the coliform bacteria that cause urinary tract infectionWhat this study adds50 ml of cranberry-lingonberry juice concentrate daily reduced recurrences of symptomatic urinary tract infection by about half compared with the control groupLactobacillus GG drink had no effect on recurrenceSelf treatment with cranberry juice may reduce the need for antimicrobials for recurrent urinary

    2017-01-01

    Full Text Available Recurrent urinary tract infection (UTI might be one of the most common problems in urological clinics. Recent research has revealed novel evidence about recurrent UTI and it should be considered a different disease from the first infection. The pathogenesis of recurrent UTI might include two mechanisms, bacterial factors and deficiencies in host defense. Bacterial survival in the urinary bladder after antibiotic treatment and progression to form intracellular bacterial communities might be the most important bacterial factors. In host defense deficiency, a defect in pathogen recognition and urothelial barrier function impairment play the most important roles. Immunodeficiency and urogenital tract anatomical abnormalities have been considered the essential risk factors for recurrent UTI. In healthy women, voiding dysfunction and behavioral factors also increase the risk of recurrent UTI. Sexual intercourse and estrogen deficiency in postmenopausal women might have the strongest association with recurrent UTI. Traditional lifestyle factors such as fluid intake and diet are not considered independent risk factors now. Serum and urine biomarkers to predict recurrent UTI from the first infection have also attracted a wide attention recently. Current clinical evidence suggests that serum macrophage colony-stimulating factor and urinary nerve growth factor have potential predictive value for recurrent UTI. Clinical trials have proven the efficacy of the oral immunoactive agent OM-89 for the prevention of UTI. Vaccines for recurrent UTI are recommended by the latest guidelines and are available on the market.

    Uncomplicated urinary tract infections (UTIs) are common, with nearly half of all women experiencing at least one UTI in their lifetime. This high frequency of infection results in huge annual economic costs, decreased workforce productivity and high patient morbidity. At least 80% of these infections are caused by uropathogenic Escherichia coli (UPEC). UPEC can reside side by side with commensal strains in the gastrointestinal tract and gain access to the bladder via colonization of the urethra. Antibiotics represent the current standard treatment for UTI; however, even after treatment, patients frequently suffer from recurrent infection with the same or different strains. In addition, successful long-term treatment has been complicated by a rise in both the number of antibiotic-resistant strains and the prevalence of antibiotic-resistance mechanisms. As a result, preventative approaches to UTI, such as vaccination, have been sought. This review summarizes recent advances in UPEC vaccine development and outlines future directions for the field.

    2014-04-01

    Catheter-associated urinary tract infections (CAUTI) are costly, common and often preventable by reducing unnecessary urinary catheter (UC) use. To summarise interventions to reduce UC use and CAUTIs, we updated a prior systematic review (through October 2012), and a meta-analysis regarding interventions prompting UC removal by reminders or stop orders. A narrative review summarises other CAUTI prevention strategies including aseptic insertion, catheter maintenance, antimicrobial UCs, and bladder bundle implementation. 30 studies were identified and summarised with interventions to prompt removal of UCs, with potential for inclusion in the meta-analyses. By meta-analysis (11 studies), the rate of CAUTI (episodes per 1000 catheter-days) was reduced by 53% (rate ratio 0.47; 95% CI 0.30 to 0.64, pSMD) in catheterisation duration (days) was -1.06 overall (p=0.065) including a statistically significant decrease in stop-order studies (SMD -0.37; pSMD, -1.54; p=0.071). No significant harm from catheter removal strategies is supported. Limited research is available regarding the impact of UC insertion and maintenance technique. A recent randomised controlled trial indicates antimicrobial catheters provide no significant benefit in preventing symptomatic CAUTIs. UC reminders and stop orders appear to reduce CAUTI rates and should be used to improve patient safety. Several evidence-based guidelines have evaluated CAUTI preventive strategies as well as emerging evidence regarding intervention bundles. Implementation strategies are important because reducing UC use involves changing well-established habits.

    Full Text Available Rainer Nowack, Rainer Birck Nephrology/Dialysis Clinic, Lindau, Germany Abstract: Cranberry (Vaccinium macrocarpon juice and extracts are widely used and recommended as folk remedy for prophylaxis of urinary tract infections (UTIs. Its putative mechanism is an anti-adhesive effect that prevents docking of bacteria on host tissues. The anti-adhesion quality is attributed to A-type proanthocyanidins (PACs, a group of polyphenols that has a restricted occurrence in cranberries and a few related plants. Clinical trials with cranberry have provided a mixed evidence on behalf of UTI prophylaxis. In some trials, a benefit could not be detected due to lower than calculated UTI recurrence rates, in others failure had retrospectively been blamed on underdosing of cranberry products. To circumvent such problems, cranberry products need to be standardized for the bioactive principle of PAC and administered at a sufficient dose. Further characterization of PAC bioavailability, improvement of the currently inconvenient prescriptions, and above all of the palatability for patients is strongly recommended. Larger staged trials should then be carried out in patients with relevant UTI risks.

    Urinary tract candidiasis is known as the most frequent nosocomial fungal infection worldwide. Candida albicans is the most common cause of nosocomial fungal urinary tract infections; however, a rapid change in the distribution of Candida species is undergoing. Simultaneously, the increase of urinary tract candidiasis has led to the appearance of antifungal resistant Candida species. In this review, we have an in depth look into Candida albicans uropathogenesis and distribution of the three most frequent Candida species contributing to urinary tract candidiasis in different countries around the world. For writing this review, Google Scholar -a scholarly search engine- (http://scholar.google.com/) and PubMed database (http://www.ncbi.nlm.nih.gov/pubmed/) were used. The most recently published original articles and reviews of literature relating to the first three Candida species causing urinary tract infections in different countries and the pathogenicity of Candida albicans were selected and studied. Although some studies show rapid changes in the uropathogenesis of Candida species causing urinary tract infections in some countries, Candida albicans is still the most important cause of candidal urinary tract infections. Despite the ranking of Candida albicans as the dominant species for urinary tract candidiasis, specific changes have occurred in some countries. At this time, it is important to continue the surveillance related to Candida species causing urinary tract infections to prevent, control and treat urinary tract candidiasis in future.

    Background Catheter-associated urinary tract infections (CAUTI) are costly, common and often preventable by reducing unnecessary urinary catheter (UC) use. Methods To summarise interventions to reduce UC use and CAUTIs, we updated a prior systematic review (through October 2012), and a meta-analysis regarding interventions prompting UC removal by reminders or stop orders. A narrative review summarises other CAUTI prevention strategies including aseptic insertion, catheter maintenance, antimicrobial UCs, and bladder bundle implementation. Results 30 studies were identified and summarised with interventions to prompt removal of UCs, with potential for inclusion in the meta-analyses. By meta-analysis (11 studies), the rate of CAUTI (episodes per 1000 catheter-days) was reduced by 53% (rate ratio 0.47; 95% CI 0.30 to 0.64, p<0.001) using a reminder or stop order, with five studies also including interventions to decrease initial UC placement. The pooled (nine studies) standardised mean difference (SMD) in catheterisation duration (days) was −1.06 overall (p=0.065) including a statistically significant decrease in stop-order studies (SMD −0.37; p<0.001) but not in reminder studies (SMD, −1.54; p=0.071). No significant harm from catheter removal strategies is supported. Limited research is available regarding the impact of UC insertion and maintenance technique. A recent randomised controlled trial indicates antimicrobial catheters provide no significant benefit in preventing symptomatic CAUTIs. Conclusions UC reminders and stop orders appear to reduce CAUTI rates and should be used to improve patient safety. Several evidence-based guidelines have evaluated CAUTI preventive strategies as well as emerging evidence regarding intervention bundles. Implementation strategies are important because reducing UC use involves changing well-established habits. PMID:24077850

    Most research on American cranberry in the prevention of urinary tract infection (UTI) has used juices. The spectrum of components in juice is limited. This study tested whether whole cranberry fruit powder (proanthocyanidin content 0.56%) could prevent recurrent UTI in 182 women with two or more UTI episodes in the last year. Participants were randomized to a cranberry (n = 89) or a placebo group (n = 93) and received daily 500 mg of cranberry for 6 months. The number of UTI diagnoses was counted. The intent-to-treat analyses showed that in the cranberry group, the UTIs were significantly fewer [10.8% vs. 25.8%, p = 0.04, with an age-standardized 12-month UTI history (p = 0.01)]. The Kaplan-Meier survival curves showed that the cranberry group experienced a longer time to first UTI than the placebo group (p = 0.04). Biochemical parameters were normal, and there was no significant difference in urinary phenolics between the groups at baseline or on day180. The results show that cranberry fruit powder (peel, seeds, pulp) may reduce the risk of symptomatic UTI in women with a history of recurrent UTIs. Copyright © 2015 John Wiley & Sons, Ltd.

  2. Diagnosis, prevention and treatment of urinary tract infections in older people.

    Bardsley, Alison

    2017-02-28

    Urinary tract infections (UTIs) are common in older people, with the prevalence increasing with age in both sexes. UTI is a frequent reason for emergency admission to hospital. There are many conditions that contribute to older people being more at risk of UTI and the main preventive strategy is to avoid the use of indwelling urethral catheters. Where an indwelling catheter is inserted its continued use should be regularly reviewed and the catheter removed, especially if the reason for insertion is incontinence and the person becomes additionally incontinent of faeces. Diagnosis of UTI can be complex because older people do not always exhibit the signs and symptoms commonly associated with UTI. Diagnosis can be further complicated by a person's inability to provide a comprehensive history and by difficulties obtaining an uncontaminated, 'clean catch' urine specimen. Antibiotic therapy should not be used routinely for people with asymptomatic bacteriuria and, where antibiotics are required, healthcare professionals should follow local prescribing guidelines.

    2011-10-01

    Full Text Available Urinary tract infections (UTI are common in childhood. In 30-50% of children with UTI the infections occur recurrently, especially in those with vesicoureteral reflux (VUR, neurogenic bladder (NB, previous cystitis or pyelonephritis and malformative uropathies. To reduce the likelihood of UTI, antibiotic prophylaxis has been regarded as the therapeutic standard for many years. However, the disadvantage of long-term antibiotic therapy is the potential for development of collateral effects and resistant organisms in the host. Such reasons have induced scientists to search for alternative modalities of UTI prevention and have contributed to determining the increasing desire for "naturalness" of the population and preventing excessive medication. The use of cranberry fulfils these needs by potentially replacing or enhancing traditional procedures. The purpose of this study was to assess the effectiveness of cranberry in preventing UTI in pediatric populations. We searched Pubmed, the Cochrane Central Register of Controlled Trials and Internet. Cranberry in patients with previous UTI was evaluated in three studies, cranberry in patients with VUR in three studies and four studies analyzed the efficacy of cranberry in children with NB. In seven of nine studies cranberry had a significant effect in preventing UTI.

    2011-11-01

    Full Text Available Abstract Background Urinary tract infections (UTIs, including upper and lower symptomatic are the most common infections in nursing homes and prevention may reduce patient suffering, antibiotic use and resistance. The spectre of agents used in preventing UTIs in nursing homes is scarcely documented and the aim of this study was to explore which agents are prescribed for this purpose. Methods We conducted a one-day, point-prevalence study in 44 Norwegian nursing homes during April-May 2006. Nursing home residents prescribed any agent for UTI prophylaxis were included. Information recorded was type of agent and dose, patient age and gender, together with nursing home characteristics. Appropriateness of prophylactic prescribing was evaluated with references to evidence in the literature and current national guidelines. Results The study included 1473 residents. 18% (n = 269 of the residents had at least one agent recorded as prophylaxis of UTI, varying between 0-50% among the nursing homes. Methenamine was used by 48% of residents prescribed prophylaxis, vitamin C by 32%, and cranberry products by 10%. Estrogens were used by 30% but only one third was for vaginal administration. Trimethoprim and nitrofurantoin were used as prophylaxis by 5% and 4%, respectively. Conclusions The agents frequently prescribed to prevent UTIs in Norwegian nursing homes lack documented efficacy including methenamine and vitamin C. Recommended agents like trimethoprim, nitrofurantoin and vaginal estrogens are infrequently used. We conclude that prescribing of prophylactic agents for UTIs in nursing homes is not evidence-based.

  11. The nature of immune responses to urinary tract infections

    Science.gov (United States)

    Abraham, Soman N.; Miao, Yuxuan

    2016-01-01

    The urinary tract is constantly exposed to microorganisms that inhabit the gastrointestinal tract, but generally the urinary tract resists infection by gut microorganisms. This resistance to infection is mainly ascribed to the versatility of the innate immune defences in the urinary tract as the adaptive immune responses are limited, particularly when only the lower urinary tract is infected. In recent years, as the strengths and weaknesses of the immune system of the urinary tract have emerged and as the virulence attributes of uropathogens are recognized, several potentially effective and unconventional strategies to contain or prevent urinary tract infections have emerged.

    To analyze epidemiological data of catheter-associated urinary tract infection (CAUTI) in critically ill patients admitted to Spanish ICUs in order to assess the need of implementing a nationwide intervention program to reduce these infections. Non-intervention retrospective annual period prevalence analysis. Participating ICUs in the ENVIN-UCI multicenter registry between the years 2007-2016. Critically ill patients admitted to the ICU with catheter-associated urinary tract infection (CAUTI). Incidence rates per 1,000 catheter-days; urinary catheter utilization ratio; proportion of CAUTIs in relation to total health care-associated infections (HAIs). A total of 187,100 patients, 137,654 (73.6%) of whom had a urinary catheter in place during 1,215,673 days (84% of days of ICU stay) were included. In 4,539 (3.3%) patients with urinary catheter, 4,977 CAUTIs were diagnosed (3.6 episodes per 100 patients with urinary catheter). The CAUTI incidence rate showed a 19% decrease between 2007 and 2016 (4.69 to 3.8 episodes per 1,000 catheter-days), although a sustained urinary catheter utilization ratio was observed (0.84 [0.82-0.86]). The proportion of CAUTI increased from 23.3% to 31.9% of all HAIs controlled in the ICU. Although CAUTI rates have declined in recent years, these infections have become proportionally the first HAIs in the ICU. The urinary catheter utilization ratio remains high in Spanish ICUs. There is room for improvement, so that a CAUTI-ZERO project in our country could be useful. Copyright © 2018 Elsevier España, S.L.U. y SEMICYUC. All rights reserved.

    Full Text Available The issues of diagnosing and treating urinary tract infections and their role in development of renal injury are being actively discussed by scientists and practicing pediatricians. The article presents the most recent data on etiological factors, pathogenesis and clinical manifestations of this disease. It provides recommendations on diagnosis and management of patients depending on their age. The article presents a discussion of antibacterial therapy course duration and indications for anti-relapse treatment. The study demonstrates that intravenous antibacterial therapy must be launched immediately in neonates in the event of pyretic fever; empirical antibacterial therapy must be launched immediately in older children after diagnosis of the urinary tract infection has been confirmed; subsequently, treatment ought to be corrected depending on the results of a bacteriological trial, sensitivity to antibiotics and effectiveness of the prescribed antibiotic. Along with normalization of urination rhythm and water intake schedule, antibacterial preventive therapy might be considered, if effective, in the event of recurrent nature of the urinary tract infection. 

  19. Urinary tract trauma

    Energy Technology Data Exchange (ETDEWEB)

    1983-09-01

    From a practical point of view, a woman who has blunt injury to the pelvic area with hematuria from the lower urinary tract, has a contused or ruptured bladder. In a man, such a situation calls for retrograde urethrography to determine if the injury is in the urethra or the bladder because the two organs are investigated differently. In both sexes, such injuries are usually associated with pelvic fractures. Massive bladder displacement and severe hemorrhage should alert one to the need for pelvic angiography to find and embolize the bleeding site within the first 24 hours after injury. For blunt trauma to the upper urinary tract an intravenous urogram with tomography is still the main examination. However, a normal intravenous urogram does not exclude serious injury. Therefore, if signs or symptoms persist, a computerized tomographic (CT) examination should be performed if available. Otherwise, a radionuclide study is advisable. Non-excretion on intravenous urography with tomography calls for selective renal arteriography to delineate the etiology. There can be serious renal trauma in the absence of hematuria, which may occur with renal pedicle injury or avulsion of the ureter. Minor forniceal ruptures may occasionally mask severe posterior renal lacerations.

    Catheter-associated urinary tract infection (UTI) in nursing home residents is a common cause of sepsis, hospital admission, and antimicrobial use leading to colonization with multidrug-resistant organisms. To develop, implement, and evaluate an intervention to reduce catheter-associated UTI. A large-scale prospective implementation project was conducted in community-based nursing homes participating in the Agency for Healthcare Research and Quality Safety Program for Long-Term Care. Nursing homes across 48 states, Washington DC, and Puerto Rico participated. Implementation of the project was conducted between March 1, 2014, and August 31, 2016. The project was implemented over 12-month cohorts and included a technical bundle: catheter removal, aseptic insertion, using regular assessments, training for catheter care, and incontinence care planning, as well as a socioadaptive bundle emphasizing leadership, resident and family engagement, and effective communication. Urinary catheter use and catheter-associated UTI rates using National Healthcare Safety Network definitions were collected. Facility-level urine culture order rates were also obtained. Random-effects negative binomial regression models were used to examine changes in catheter-associated UTI, catheter utilization, and urine cultures and adjusted for covariates including ownership, bed size, provision of subacute care, 5-star rating, presence of an infection control committee, and an infection preventionist. In 4 cohorts over 30 months, 568 community-based nursing homes were recruited; 404 met inclusion criteria for analysis. The unadjusted catheter-associated UTI rates decreased from 6.78 to 2.63 infections per 1000 catheter-days. With use of the regression model and adjustment for facility characteristics, the rates decreased from 6.42 to 3.33 (incidence rate ratio [IRR], 0.46; 95% CI, 0.36-0.58; P < .001). Catheter utilization was 4.5% at baseline and 4.9% at the end of the project. Catheter

    2014-01-01

    Full Text Available Context: In patients with neurogenic lower urinary tract dysfunction due to Spinal Cord Injury (SCI, recurrent Urinary Tract Infections (UTI, is a frequently encountered clinical problem. Often, conventional preventive measures are not successful. Aims: To treat the patients of SCI suffering from recurrent UTI with classical homoeopathy as add-on to standard urologic care. Materials and Methods: After exclusion of morphological abnormalities and initiation of a standard regime for prophylaxis, all patients with a neurogenic lower urinary tract dysfunction due to SCI, with more than three symptomatic UTI/year, were offered additional homoeopathic care. Symptoms were fever, incontinence, increased spasticity, decreased bladder capacity or pain/decreased general health combined with significant bacteriuria. Descriptive statistics was used for analysis. Results: Eight patients were followed up for a median period of 15 months. Five patients remained free of UTI, whereas UTI frequency was reduced in three patients. Conclusion: Our initial experience with homoeopathic prevention of UTI as add on to standard urologic prophylactic measures is encouraging. For an evidence-based evaluation of this concept, prospective studies are required. Keys for the positive outcome of this case series are co-operation of well-qualified partners, mutual respect and the motivation to co-operate closely.

    We examined the preventive effect of probiotic and antibiotics versus antibiotics alone, in children with recurrent urinary tract infections (RUTI) in a preliminary randomized clinical trial. Between March 2007 and April 2011, children with the history of RUTI and unilateral vesicoureteral reflux (VUR) were randomly assigned to receive concomitant probiotic and antibiotics (Lactobacillus acidophilus and bifidobacterium lactis, 10(7)/ml, as 0.25 ml/kg three times a day regimen in addition to Nitrofurantoin, 1mg/kg daily (group I). In group II, all children received conventional prophylactic antibiotics alone (Nitrofurantoin, 1 mg/kg daily). Randomization was performed via using the random numerals table in a 1:1 manner with stratification by sex, age and grade of reflux. The urine examinations were done monthly and the incidence of UTI was evaluated in these two groups. Forty-one children (age: 8.3±3.1 years) in group I and 44 children (age: 8.0±3.0 years) in group II were compared. During the course of three years, 39% in group I and 50% of participants in group II experienced RUTIs (P=0.4). Incidences of UTI - febrile and afebrile - reduced in both groups without any significant differences after two years of prophylaxis. Also, incidence of afebrile UTIs did not significantly differ (0.51±1.30 and 0.81±1.41 respectively, P =0.3); however, the incidence of febrile UTIs in particular were lower in group I (0.00±0.00 versus 0.13±0.40, P =0.03) in the last year. The consumption of probiotic and antibiotics in children with RUTI is safe and more effective in reducing the incidence of febrile UTI in comparison to prophylactic antibiotics alone.

  8. [Urinary tract infection and neurogenic bladder].

    Science.gov (United States)

    Salomon, J; Gory, A; Bernard, L; Ruffion, A; Denys, P; Chartier-Kastler, E

    2007-05-01

    One of the main complications of spinal cord injury is neurogenic bladder when the bladder fails to empty spontaneously. Urinary tract infection is the leading cause of morbidity and the second cause of mortality in these subjects. Patient education and personalized medical follow-up must ensure adapted management depending on the risk factors and the voiding mode. The risk of urinary tract infection can be decreased by perfect neurological control of detrusor activity combined with a method of drainage: intermittent self-catheterization. Despite these measures, many patients experience recurrent symptomatic urinary tract infections. Repeated antibiotic therapy increases the risk of selection of multiresistant bacteria without reducing either the incidence or the severity of symptomatic urinary tract infections. Asymptomatic bacteriuria is very frequent in patients treated by intermittent catheterization and does not justify antibiotic therapy, as antiseptics and urinary alkalinizers or acidifiers have been shown to be effective. "Antibiocycle" strategies could have a beneficial role by significantly decreasing the number of infections and hospitalizations with no major ecological risks, by using molecules that are well tolerated orally with a low selection pressure. All febrile urinary tract infections require rapid investigation and an urgent urological and infectious diseases opinion (abscess, severe sepsis, resistance). The SPILF-AFU 2002 consensus conference provided answers to major questions concerning the definition, treatment and prevention of nosocomial urinary tract infection, especially in a context of neurogenic bladder.

    Existing knowledge of emergency department (ED) catheter-associated urinary tract infection (CAUTI) prevention is limited. We aimed to describe the motivations, perceived risks for CAUTI acquisition, and strategies used to address CAUTI risk among EDs that had existing CAUTI prevention programs. In this qualitative comparative case study, we enrolled early-adopting EDs, that is, those using criteria for urinary catheter placement and tracking the frequency of catheters placed in the ED. At 6 diverse facilities, we conducted 52 semistructured interviews and 9 focus groups with hospital and ED participants. All ED CAUTI programs originated from a hospitalwide focus on CAUTI prevention. Staff were motivated to address CAUTI because they believed program compliance improved patient care. ED CAUTI prevention was perceived to differ from CAUTI prevention in the inpatient setting. To identify areas of ED CAUTI prevention focus, programs examined ED workflow and identified 4 CAUTI risks: (1) inappropriate reasons for urinary catheter placement; (2) physicians' limited involvement in placement decisions; (3) patterns of urinary catheter overuse; and (4) poor insertion technique. Programs redesigned workflow to address risks by (1) requiring staff to specify the medical reason for catheter at the point of order entry and placement; (2) making physicians responsible for determining catheter use; (3) using catheter alternatives to address patterns of overuse; and (4) modifying urinary catheter insertion practices to ensure proper placement. Early-adopting EDs redesigned workflow to minimize catheter use and ensure proper insertion technique. Assessment of ED workflow is necessary to identify and modify local practices that may increase CAUTI risk.

    Full Text Available Urinary tract infections (UTI are frequent conditions in children. Untreated urinary tract infections can lead to serious kidney problems that could threaten the life of the child. Therefore, early detection and treatment of urinary tract infection is important. In older children, urinary tract infections may cause obvious symptoms such as stomach ache and disuria. In infants and young children, UTIs may be harder to detect because of less specific symptoms. Recurrences are common in children with urinary abnormalities such as neurogenic bladder, vesicourethral reflux or those with very poor toilet and hygiene habits. This article reviews the diagnostic approach and presents the current data related to the roles of radiologic imaging, surgical correction and antibiotic prophylaxis of UTIs in children.

    Preventing catheter-associated urinary tract infections is in the forefront of health care quality. However, nurse and physician engagement is a common barrier in infection prevention efforts. After implementation of a multidisciplinary catheter-associated urinary tract infection (CAUTI) prevention campaign, we studied the impact of our campaign and showed its association with reducing the CAUTI rate and catheter utilization and the positive effect on health care workers' engagement and perspectives. CAUTI prevention campaigns can lead to lower infection rates and change health care workers' perspective. Copyright © 2016 Association for Professionals in Infection Control and Epidemiology, Inc.

    To assess the properties of a medical device containing xyloglucan, propolis and hibiscus to create a bioprotective barrier to avoid the contact of uropathogenic Escherichia coli strains on cell walls in models of intestinal (CacoGoblet) and uroepithelial (RWPE-1) cells (derived from normal human prostate epithelium). Two uropathogenic E. coli strains (expressing type 1 fimbriae and P fimbriae) were used to assess, by electronic microscopy and ELISA, the barrier properties of the medical device. The antimicrobial activity was assessed in broth dilution assays. The three components (xyloglucan, propolis and hibiscus) did not alter E. coli cell integrity in intestinal and uroepithelial cell models and were devoid of antibacterial activity. The three components avoided bacterial contact in both cell monolayers. The nonpharmacological barrier properties of xyloglucan, propolis and hibiscus confirm the role of the medical device for the management of urinary tract infections.

    Neuropathic or neurogenic bladder describes a process of dysfunctional voiding as the result of injury in the brain, spinal cord or nerves innervating the bladder. People with neuropathic bladder, such as from spinal cord injury (SCI), are at significant risk of morbidity from urinary tract infections (UTI). Effective methods to prevent UTI in people with SCI have been sought for many years. Probiotics (micro-organisms that exert beneficial health effects in the host) have been recommended for bacterial interference of the urological tract to reduce colonisation by uropathogen and to manage the dual problems of infection and antibiotic resistance. This review looked at the benefits and harms of probiotics in preventing symptomatic UTI in people with neuropathic bladder compared with placebo, no therapy, or non-antibiotic prophylaxis (cranberry juice, methenamine hippurate, topical oestrogen). We searched the Cochrane Kidney and Transplant Specialised Register up to 10 March 2017 through contact with the Information Specialist using search terms relevant to this review. Studies in the Specialised Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal, and ClinicalTrials.gov. All randomised controlled trials (RCTs), quasi-RCTs and cross-over RCTs looking at the use of probiotics for the prophylaxis of UTI in people with neuropathic bladders was considered for inclusion. Men, women and children of all ages with neuropathic bladders from neurological injury such as suprapontine, supra sacral and sacral aetiologies was included. All bladder management types, including reflex voiding, time voiding, indwelling and intermittent catheterization were eligible for this review.Studies comparing probiotics to placebo, no treatment or other non-antibiotic prophylaxis was included. Studies comparing probiotics with antibiotics or in combination with antibiotics were

    Full Text Available Introduction: Although effectiveness of cranberry for preventing urinary tract infection (UTI has been reported in Iranian traditional medicine and recent studies there is still controversy in this regard. Therefore, the present study was designed with a meta-analytic approach aiming to evaluate the effect of prophylaxis prescription of cranberry in prevention of UTI in children.Methods: In this study, a thorough search was performed in Medline, Embase, Web of Sciences, Scopus and CINHAL databases by the end of August 2017. Using keywords related to urinary tract infection combined with words related to cranberry, search strategy was designed. The articles were summarized and finally, the role of cranberry extract consumption in decreasing the incidence of UTI was evaluated by reporting odds ratio (OR and 95% confidence interval (95% CI. Results: In the end, 10 studies were included (414 cases in control group and 380 in cranberry extract treatment group. Analyses showed that prescription of cranberry significantly reduced the odds of UTI manifestation in children compared to placebo (OR=0.31; 95% CI: 0.21 to 0.46; p

    Radical hysterectomy is associated with a significant amount of urinary functional complications and a negative impact on quality of life. The aim of this review is to provide a comprehensive overview of the neurological etiology of lower urinary tract dysfunction following radical hysterectomy and to establish an optimal postoperative management strategy. We performed a comprehensive overview using the following terms: "radical hysterectomy" and "urologic diseases etiology" or "urologic disease prevention and control". The reported incidence of lower urinary tract dysfunction after radical hysterectomy varies from 12 to 85%. Several animal and clinical urodynamic studies corroborate the neurologic etiology of the dysfunction. Lower urinary tract dysfunction is a common postoperative finding (70-85%) but spontaneous recovery is to be expected within 6-12 months after surgery. The most frequent long term sequela is stress urinary incontinence (40% of cases) and its management is complex and challenging. Postoperative refractory overactive bladder and bladder underactivity can be treated by neuromodulation of sacral roots and superior hypogastric plexus, respectively. In the absence of good clinical predictors, preoperative urodynamic examinations could have a role in understanding the pathophysiology of the dysfunction before such interventions. The pathophysiology of lower urinary tract dysfunction following radical hysterectomy is multifactorial. Its management is complex and should be multidisciplinary.

    To investigate the effects of hyaluronic acid (HA) in rat with Escherichia coli-induced urinary tract infection and duration of its effect. HA is a component of the glycosaminoglycan layer, and is known to interfere with the attachment of E. coli to the urothelium. The rats were divided into various groups. The E. coli-only group in which phosphate-buffered saline was instilled before E. coli (fimH+, sfa+, papA+) inoculation; HA-1, HA-3, HA-5, and HA-7 groups in which HA (0.5 mL, 0.5%) was instilled 1, 3, 5, 7 days before E. coli inoculation, respectively. To assess the symptomatic changes, we examined the voiding interval (VI) of E. coli-only group and HA-1 group before and after E. coli inoculation. Atomic force microscopy was performed to investigate the change in the urothelium before and after HA treatment. Bacterial growth rate in the bladder was significantly higher in the E. coli-only group (84.6%) than in the HA-1 (20.0%), HA-3 (23.5%), and HA-5 groups (7.7%) (P <.05). The VI in E. coli-only group decreased from the first to third day after the induction of cystitis. The VI in E. coli-only group was significantly shorter than in HA-1 group (P <.05). No pathological evidence of acute inflammation was observed in the bladder and kidney of culture-negative HA groups. Atomic force microscopy showed HA coating on the urothelium. This study shows that HA has an effect on the protection mechanism against the invasion of E. coli and that its effect duration is about seven days. Copyright 2010 Elsevier Inc. All rights reserved.

    Full Text Available Background. Radical hysterectomy is performed on woman with cervical cancer or endometrial cancer that has spread to the cervix. Aims. To find whether our modified radical hysterectomy represents nerve sparing. Methods. In 28 patients, modified radical hysterectomy was applied (study group and the width of the parametria and vaginal cuff were measured. Using a point-counting technique, nerve areal density was determined in cross sections of resected parametria at 0.5 cm (A, 1 cm (B, and 1.5 cm (C from the cervix. The results were compared with 26 control patients who underwent classic radical hysterectomy. In the study group urodynamic measurements were performed after operation, and correlations with histologic data were calculated. The survival rates and adjuvant treatment were compared between the groups. Results. Adjuvant treatment was given to 53.57 % in the study and 65.38 % of patients in the control group (P > 0.3. The survival rate after 3 years was 92.85 % in the study and 84.61 % in the control group after more than 5 years. The width of the resected parametria was smaller in the study (mean: right 15.50 mm, left 15.71 mm compared with the control group (mean: right 22.69 mm; P < 0.013; left 22.96 mm; P < 0.011. The nerve areal density in the lateral part of the right parametrium (C right 6.2 % was lower in the study than in the control group (C right 9.7 %; P < 0.01. There were several correlations between parametrial width, nerve areal density and urodynamic parameters. Conclusions. Modified radical hysterectomy is less radical, and apparently also nerve sparing. It does not influence survival rates and does not impair the urinary tract function.

    Objectives: We performed a phase I trial to assess the safety and tolerance of a Lactobacillus vaginal suppository for prevention of recurrent UTI. Methods: Premenopausal women with a history of recurrent UTI were randomized to use L. crispatus CTV-05 or placebo vaginal suppositories daily for five days. Results: 30 women were randomized (15 to L. crispatus CTV-05). No severe adverse events occurred. Mild to moderate vaginal discharge and genital irritation were reported by women in both study arms. Seven women randomized to L. crispatus CTV-05 developed pyuria without associated symptoms. Most women had high concentrations of vaginal H202-producing lactobacilli before randomization. L. crispatus, L. jensenii, and L. gasseri were the most common Lactobacillus species identified, with stable prevalence over time. Conclusions: L. crispatus CTV-05 can be given as a vaginal suppository with minimal sideeffects to healthy women with a history of recurrent UTI. Mild inflammation of the urinary tract was noted in some women. PMID:18288237

    Candida species are unusual causes of urinary tract infection (UTI) in healthy individuals, but common in the hospital setting or among patients with predisposing diseases and structural abnormalities of the kidney and collecting system. The urinary tract may be invaded in either an antegrade fashion from the bloodstream or retrograde via the urethra and bladder. Candida species employ a repertoire of virulence factors, including phenotypic switching, dimorphism, galvano - and thigmotropism, and hydrolytic enzymes, to colonize and then invade the urinary tract. Antegrade infection occurs primarily among patients predisposed to candidemia. The process of adherence to and invasion of the glomerulus, renal blood vessels, and renal tubules by Candida species was elegantly described in early histopathologic studies. Armed with modern molecular biologic techniques, the various virulence factors involved in bloodborne infection of the kidney are gradually being elucidated. Disturbances of urine flow, whether congenital or acquired, instrumentation of the urinary tract, diabetes mellitus, antimicrobial therapy, and immunosuppression underlie most instances of retrograde Candida UTI. In addition, bacterial UTIs caused by Enterobacteriaceae may facilitate the initial step in the process. Ascending infections generally do not result in candidemia in the absence of obstruction.

    Urinary tract infections (UTIs) are frequent, recurrent, and lifelong for patients with neurogenic bladder and present challenges in diagnosis and treatment. Patients often present without classic symptoms of UTI but with abdominal or back pain, increased spasticity, and urinary incontinence. Failure to recognize and treat infections can quickly lead to life-threatening autonomic dysreflexia or sepsis, whereas overtreatment contributes to antibiotic resistance, thus limiting future treatment options. Multiple prevention methods are used but evidence-based practices are few. Prevention and treatment of symptomatic UTI requires a multimodal approach that focuses on bladder management as well as accurate diagnosis and appropriate antibiotic treatment.

    Full Text Available Urinary tract infection (UTI is one of the most common paediatric infections. By the time children are 5 years old, about 8% of girls and about 1-2% of boys have had at least one episode of UTI. UTIs are caused mainly by colonic bacteria, such as Escherichia coli, followed by Klebsiella and Proteus. However, any organism that gains access to the urinary tract system may cause infection, including fungi (Candida species and viruses. In some instances, UTI results in recognition of an important underlying structural abnormality of the urinary tract. The febrile infant or child with clinically significant bacteriuria and no other site of infection to explain the fever, even in the absence of systemic symptoms has UTI. Signs and symptoms of UTIs vary depending on the child's age and on which part of the urinary tract is infected. The diagnosis of UTI is based on routine microscopic examination and culture of a properly collected urine specimen. Imaging studies are done in selected patients to identify anatomic abnormalities. Most cases of uncomplicated UTI respond readily to outpatient antibiotic treatment without further sequelae. All patients should have close follow-up to evaluate response to antibiotics and to prevent the development of long term complication.

    To provide an update of the definition, epidemiology, clinical presentation, investigation, treatment, and prevention of recurrent urinary tract infections in women. Continuous antibiotic prophylaxis, post-coital antibiotic prophylaxis, and acute self-treatment are all efficient alternatives to prevent recurrent urinary tract infection. Vaginal estrogen and cranberry juice can also be effective prophylaxis alternatives. A search of PubMed and The Cochrane Library for articles published in English identified the most relevant literature. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. There were no date restrictions. This update is the consensus of the Sub-Committee on Urogynaecology of the Society of Obstetricians and Gynaecologists of Canada. Recommendations were made according to the guidelines developed by the Canadian Task Force on Preventive Health Care (Table 1). Recurrent urinary tract infections need careful investigation and can be efficiently treated and prevented. Different prophylaxis options can be selected according to each patient's characteristics.

    Urinary tract infections (UTIs) are commonly reported by people with multiple sclerosis (PwMS) and significantly impact quality of life. To provide an overview of the problem of UTIs in PwMS and offer a practical approach for the diagnosis and management. A review of the literature through a Pubmed search up to October 2015 was performed using the following keywords: multiple sclerosis, neurogenic bladder, urinary tract infections, relapse, dipsticks, culture, recurrent and prevention. Noteworthy topics include the definition of a confirmed symptomatic UTI as a positive urine culture defined by >10(5) colony-forming units (CFU)/mL or >10(4) CFU/mL if a urethral catheter urine sample is taken, or any count of bacteria in a suprapubic bladder puncture specimen, both in addition to symptoms including fever, pain, changes in lower urinary tract symptoms or neurological status. Urinalysis is useful to exclude a UTI; however, on its own is insufficient to confirm a UTI, for which urine culture is required. Experts advise asymptomatic UTIs should not be treated except in the context of an acute relapse. From international guidelines, there is no validated strategy to prevent recurrent UTIs in PwMS. This review provides an overview of the diagnosis, treatment and prevention of UTIs in the setting of multiple sclerosis (MS). © The Author(s), 2016.

    Postmenopausal lower urinary tract atrophy and its relations to recurrent urinary infections in elderly women are studied. Clinical aspects, functional and histological aspects and hypothetic mechanisms of atrophy are reported, epidemiologic data, mechanisms of urinary infections and of estrogen effects are reviewed and reports on the results of local or systemic use of drugs from the literature are presented. Local administration of estrogen seems to be efficient on the urinary tract. Local treatment is less dangerous and cheaper than systemic treatment. Hormonal treatment is one of the preventive measures against recurrent urinary infections in elderly women.

    The preventive health care needs of people with disabilities often go unmet, resulting in medical complications that may require hospitalization. Such complications could be due, in part, to difficulty accessing care or the quality of ambulatory care services received. To use hospitalizations for urinary tract infections (UTIs) as a marker of the potential quality of ambulatory care services received by people affected by spina bifida. MarketScan inpatient and outpatient medical claims data for 2000 through 2003 were used to identify hospitalizations for UTI, which is an ambulatory care sensitive condition, for people affected by spina bifida and to calculate inpatient discharge rates, average lengths of stay, and average medical care expenditures for such hospitalizations. People affected by spina bifida averaged 0.5 hospitalizations per year, and there were 22.8 inpatient admissions with UTI per 1000 persons with spina bifida during the period 2000-2003, in comparison to an average of 0.44 admission with UTI per 1000 persons for those without spina bifida. If the number of UTI hospitalizations among people affected by spina bifida were reduced by 50%, expenditures could be reduced by $4.4 million per 1000 patients. Consensus on the evaluation and management of bacteriuria could enhance clinical care and reduce the disparity in UTI discharge rates among people affected by spina bifida compared to those without spina bifida. National evidence-based guidelines are needed.

  20. Cold stress induces lower urinary tract symptoms.

    Cold stress as a result of whole-body cooling at low environmental temperatures exacerbates lower urinary tract symptoms, such as urinary urgency, nocturia and residual urine. We established a model system using healthy conscious rats to explore the mechanisms of cold stress-induced detrusor overactivity. In this review, we summarize the basic findings shown by this model. Rats that were quickly transferred from room temperature (27 ± 2°C) to low temperature (4 ± 2°C) showed detrusor overactivity including increased basal pressure and decreased voiding interval, micturition volume, and bladder capacity. The cold stress-induced detrusor overactivity is mediated through a resiniferatoxin-sensitve C-fiber sensory nerve pathway involving α1-adrenergic receptors. Transient receptor potential melastatin 8 channels, which are sensitive to thermal changes below 25-28°C, also play an important role in mediating the cold stress responses. Additionally, the sympathetic nervous system is associated with transient hypertension and decreases of skin surface temperature that are closely correlated with the detrusor overactivity. With this cold stress model, we showed that α1-adrenergic receptor antagonists have the potential to treat cold stress-exacerbated lower urinary tract symptoms. In addition, we showed that traditional Japanese herbal mixtures composed of Hachimijiogan act, in part, by increasing skin temperature and reducing the number of cold sensitive transient receptor potential melastatin channels in the skin. The effects of herbal mixtures have the potential to treat and/or prevent the exacerbation of lower urinary tract symptoms by providing resistance to the cold stress responses. Our model provides new opportunities for utilizing animal disease models with altered lower urinary tract functions to explore the effects of novel therapeutic drugs. © 2013 The Japanese Urological Association.

  1. Cost-effectiveness of cranberries vs antibiotics to prevent urinary tract infections in premenopausal women: a randomized clinical trial.

    Judith E Bosmans

    Full Text Available Urinary tract infections (UTIs are common and result in an enormous economic burden. The increasing prevalence of antibiotic-resistant microorganisms has stimulated interest in non-antibiotic agents to prevent UTIs.To evaluate the cost-effectiveness of cranberry prophylaxis compared to antibiotic prophylaxis with trimethoprim-sulfamethoxazole (TMP-SMX over a 12 month period in premenopausal women with recurrent UTIs.An economic evaluation was performed alongside a randomized trial. Primary outcome was the number of UTIs during 12 months. Secondary outcomes included satisfaction and quality of life. Healthcare utilization was measured using questionnaires. Missing data were imputed using multiple imputation. Bootstrapping was used to evaluate the cost-effectiveness of the treatments.Cranberry prophylaxis was less effective than TMP-SMX prophylaxis, but the differences in clinical outcomes were not statistically significant. Costs after 12 months in the cranberry group were statistically significantly higher than in the TMP-SMX group (mean difference €249, 95% confidence interval 70 to 516. Cost-effectiveness planes and cost-effectiveness acceptability curves showed that cranberry prophylaxis to prevent UTIs is less effective and more expensive than (dominated by TMP-SMX prophylaxis.In premenopausal women with recurrent UTIs, cranberry prophylaxis is not cost-effective compared to TMP-SMX prophylaxis. However, it was not possible to take into account costs attributed to increased antibiotic resistance within the framework of this randomized trial; modeling studies are recommended to investigate these costs. Moreover, although we based the dosage of cranberry extract on available evidence, this may not be the optimal dosage. Results may change when this optimal dosage is identified.ISRCTN.org ISRCTN50717094.

    We retrospectively reviewed the results of ureteral reimplantation in infants with primary vesicoureteral reflux (VUR) to evaluate the effect on prevention of urinary tract infection (UTI) and renal growth. From July 1991 to December 2001, a total of 205 infants (180 boys and 25 girls) with primary VUR underwent ureteral reimplantation at the Department of Urology, Osaka Medical Center and Research Institute for Maternal and Child Health, Osaka, Japan. Indications for surgery were high-grade reflux (grade IV-V), breakthrough UTI and non-compliance of medical treatment. Age at surgery raged from 1 to 11 months (mean, 6.4 months). Ureteral reimplantation was performed according to Cohen's method. Only two of 336 refluxing ureters required ureteral tailoring. Follow-up ranged from 12 to 110 months (mean, 64 months). Surgical outcome, frequency of UTI and individual renal growth measured by 99m Tc-dimercaptosuccinic acid (DMSA) scintigraphy was evaluated. Postoperative ultrasound and voiding cystourethrography showed neither residual reflux nor ureterovesical obstruction. Contralateral low grade reflux occurred in six of 74 patients (8.1%) who had unilateral reflux preoperatively. After reimplantation, 10 patients documented 13 febrile UTI. Eleven of the 13 episodes occurred early in the postoperative period (<6 months). Frequency of febrile UTI reduced from 0.23538 before surgery to 0.00894 and 0.00081 per patient per month at 6 and 12 months after surgery, respectively. No development of renal scarring was seen in postoperative DMSA scan. Changes of differential renal function was <0.05 in all patients. The present results show ureteral reimplantation in infants is safe and very effective for the prevention of UTI. After surgical treatment in infancy, individual renal growth of children with primary VUR is stable. (authors)

    Urinary tract infections (UTIs) are a major recurrent problem for spinal cord injury (SCI) patients. Repeated antibiotic treatments contribute to the emergence of multidrug-resistant bacteria (MDRB). We evaluated the use of weekly oral cycling antibiotics (WOCA) in the prevention of UTIs over a mean follow-up period of 53 months (median follow-up period: 57 months) and analyzed the risk of MDRB emergence. We conducted a cross-sectional study of adult SCI patients with neurogenic bladder who were receiving the WOCA regimen. We included 50 patients, mainly men (60%), with a mean age of 51±13.5 years. Overall, 66% of patients had been paraplegic or tetraplegic for 19.4±14.3 years; 92% underwent intermittent catheterization; and 36% had no postvoid residual. The number of febrile and non-febrile UTIs significantly reduced after WOCA initiation (9.45 non-febrile UTIs before WOCA initiation vs. 1.57 after; 2.25 febrile UTIs before WOCA initiation vs. 0.18 after; P=0.0001). Only one adverse event was reported during the follow-up period. The number of MDRB-colonized patients decreased from 9/50 to 4/50 during the follow-up period. WOCA is an effective and safe strategy to prevent UTIs in SCI patients with neurogenic bladder. WOCA does not lead to the emergence of MDRB resistance and even seems to reduce MDRB carriage.

  4. URINARY TRACT INFECTIONS IN PREGNANCY

    Directory of Open Access Journals (Sweden)

    Full Text Available Urinary tract infections frequently affect pregnant mothers. This problem causes significant morbidity and healthcare expenditure. Three common clinical manifestations of UTIs in pregnancy are: asymptomatic bacteriuria, acute cystitis and acute pyelonephritis. Escherichia coli remains the most frequent organism isolated in UTIs. All pregnant mothers should be screened for UTIs in pregnancy and antibiotics should be commenced without delay. Urine culture and sensitivity is the gold standard in diagnosing UTIs. Without treatment, asymptomatic bacteriuria in pregnancy is associated with preterm delivery, intrauterine growth retardation, low birth weight, maternal hypertension, pre-eclampsia and anaemia. Acute pyelonephritis can lead to maternal sepsis. Recurrent UTIs in pregnancy require prophylactic antibiotic treatment.

  5. The effect of hormones on the lower urinary tract.

    The female genital and lower urinary tracts share a common embryological origin, arising from the urogenital sinus and both are sensitive to the effects of the female sex steroid hormones throughout life. Estrogen is known to have an important role in the function of the lower urinary tract and estrogen and progesterone receptors have been demonstrated in the vagina, urethra, bladder and pelvic floor musculature. In addition estrogen deficiency occurring following the menopause is known to cause atrophic change and may be associated with lower urinary tract symptoms such as frequency, urgency, nocturia, urgency incontinence and recurrent infection. These may also co-exist with symptoms of urogenital atrophy such as dyspareunia, itching, vaginal burning and dryness. Epidemiological studies have implicated estrogen deficiency in the aetiology of lower urinary tract symptoms with 70% of women relating the onset of urinary incontinence to their final menstrual period. Whilst for many years systemic and vaginal estrogen therapy was felt to be beneficial in the treatment of lower urinary and genital tract symptoms this evidence has recently been challenged by large epidemiological studies investigating the use of systemic hormone replacement therapy as primary and secondary prevention of cardiovascular disease and osteoporosis. The aim of this paper is to examine the effect of the sex hormones, estrogen and progesterone, on the lower urinary tract and to review the current evidence regarding the role of systemic and vaginal estrogens in the management of lower urinary tract symptoms and urogenital atrophy.

    To compare the effectiveness of bacterial interference versus placebo in preventing urinary tract infection (UTI). The main outcome measure was the numbers of episodes of UTI/patient-year. Randomization was computer generated, with allocation concealment by visibly indistinguishable products distributed from a core facility. The healthcare providers and those assessing the outcomes were unaware of the group allocation. Adult patients (n = 65) with neurogenic bladder after spinal cord injury and a history of recurrent UTI were randomized in a 3:1 ratio to receive either Escherichia coli HU2117 or sterile saline. Urine cultures were obtained weekly during the first month and then monthly for 1 year. The patients were evaluable if they remained colonized with E. coli HU2117 for >4 weeks (experimental group). The trial is closed to follow-up. Of the 59 patients who received bladder inoculations, 27 were evaluable (17 in the experimental group and 10 in the placebo group). The 2 study groups had comparable clinical characteristics. Of 17 patients colonized with E. coli HU2117 and the 10 control patients, 5 (29%, 95% confidence interval 0.11-0.56) and 7 (70%, 95% confidence interval 0.35-0.92) developed >1 episode of UTI (P = .049; 1-sided Fisher's exact test), respectively. The average number of episodes of UTI/patient-year was also lower (P = .02, Wilcoxon rank sum test) in the experimental (0.50) than in the control group (1.68). E. coli HU2117 did not cause symptomatic UTI. Bladder colonization with E. coli HU2117 safely reduces the risk of symptomatic UTI in patients with spinal cord injury. Effective, but less complex, methods for achieving bladder colonization with E. coli HU2117 are under investigation. Published by Elsevier Inc.

    Purpose: To assess the impact of bladder instillations of hyaluronic acid (HA) on the prevalence of urinary tract infection (UTI) in patients receiving emergency radiotherapy for metastatic spinal cord compression. Methods and Materials: Patients were recruited consecutively at one center and assigned to usual care (UC) (n = 34, mean age 62.2 years) or UC with once-weekly HA instillation (UC + HA) (Cystistat: 40 mg in 50 mL phosphate-buffered saline) (n = 37; mean age, 63.1 years). All patients had an indwelling catheter and received radiotherapy. UTI status was assessed at baseline and during hospitalization. Results: At baseline, patient groups were comparable, except for the prevalence of UTI at baseline, which was 11.8% and 0% in the UC and UC + HA patients, respectively (p = 0.0477). During hospitalization, 76.5% (vs. 11.8% at baseline, p < 0.0001) of the UC patients had a UTI compared with 13.5% (vs. 0% at baseline, p = 0.0541) of the UC + HA patients (p < 0.0001). Both groups were hospitalized for similar periods (19.8 days [UC] vs. 18.5 days, p = 0.4769) and received equivalent radiotherapy sessions (4.6 [UC] vs. 5.8 sessions, p = 0.2368). Conclusions: Patients receiving UC + HA had a 5.7-fold decrease in UTI prevalence over the hospitalization period compared to UC patients, suggesting that bladder instillations of HA effectively prevent UTI in patients with indwelling catheters receiving radiotherapy for nerve compression

    Adenosine-5'-triphosphate (ATP) is a neurotransmitter and inflammatory cytokine implicated in the pathophysiology of lower urinary tract disease. ATP additionally reflects microbial biomass thus has potential as a surrogate marker of urinary tract infection (UTI). The optimum clinical sampling method for ATP urinalysis has not been established. We tested the potential of urinary ATP in the assessment of lower urinary tract symptoms, infection and inflammation, and validated sampling methods for clinical practice. A prospective, blinded, cross-sectional observational study of adult patients presenting with lower urinary tract symptoms (LUTS) and asymptomatic controls, was conducted between October 2009 and October 2012. Urinary ATP was assayed by a luciferin-luciferase method, pyuria counted by microscopy of fresh unspun urine and symptoms assessed using validated questionnaires. The sample collection, storage and processing methods were also validated. 75 controls and 340 patients with LUTS were grouped as without pyuria (n = 100), pyuria 1-9 wbc μl(-1) (n = 120) and pyuria ≥10 wbc μl(-1) (n = 120). Urinary ATP was higher in association with female gender, voiding symptoms, pyuria greater than 10 wbc μl(-1) and negative MSU culture. ROC curve analysis showed no evidence of diagnostic test potential. The urinary ATP signal decayed with storage at 23°C but was prevented by immediate freezing at ≤ -20°C, without boric acid preservative and without the need to centrifuge urine prior to freezing. Urinary ATP may have a role as a research tool but is unconvincing as a surrogate, clinical diagnostic marker.

    The urinary tract, previously considered a sterile body niche, has emerged as the host of an array of bacteria in healthy individuals, revolutionizing the urology research field. To review the literature on microbiome implications in the urinary tract and the usefulness of probiotics/prebiotics and diet as treatment for urologic disorders. A systematic review was conducted using PubMed and Medline from inception until July 2016. The initial search identified 1419 studies and 89 were included in this systematic review. Specific bacterial communities have been found in the healthy urinary tract. Changes in this microbiome have been observed in certain urologic disorders such as urinary incontinence, urologic cancers, interstitial cystitis, neurogenic bladder dysfunction, sexually transmitted infections, and chronic prostatitis/chronic pelvic pain syndrome. The role of probiotics, prebiotics, and diet as treatment or preventive agents for urologic disorders requires further investigation. There is a microbiome associated with the healthy urinary tract that can change in urologic disorders. This represents a propitious context to identify new diagnostic, prognostic, and predictive microbiome-based biomarkers that could be used in clinical urology practice. In addition, probiotics, prebiotics, and diet modifications appear to represent an opportunity to regulate the urinary microbiome. We review the urinary microbiome of healthy individuals and its changes in relation to urinary disorders. The question to resolve is how we can modulate the microbiome to improve urinary tract health. Copyright © 2016 European Association of Urology. Published by Elsevier B.V. All rights reserved.

    Urinary tract dysfunction in older patients has a multifactorial aetiology and is not a uniform clinical condition. Changes due to physiological ageing as well as comorbidity and polypharmacy, can produce several dynamic conditions such as urinary incontinence and urinary retention. Lower urinary tract symptoms increase with age in both sexes and are a major problem in older patients due to their medical and psychosocial consequences. For these reasons, in assessing urinary dysfunction in older patients, we should consider external circumstances such as polypharmacy, poor mobility, affective and cognitive disorders and also accessibility to housing.

Due to its high incidence and recurrence, problems are faced in the treatment with antibiotics. Cranberry being herbal remedy have long been the focus of interest for their beneficial effects in preventing urinary tract infections. This study was conducted to analyse in vitro activity of cranberry (Vaccinium macrocarpon) on uropathogenic E coli in uncomplicated urinary tract infections. In this laboratory based single group experimental study, anti-bacterial activity of Vaccinium macrocarpon concentrate on urinary tract E coli was investigated, in vitro. Ninety-six culture positive cases of different uropathogens were identified. Vaccinium macrocarpon concentrate at different concentrations was prepared in distilled water and put in wells punched in nutrient agar. E coli isolates were inoculated on the plates and incubated at 37 °C for 24 hours. A citric acid solution of the same pH as that of Vaccinium macrocarpon was used and put in a well on the same plate to exclude the effect of pH. A total of 35 isolates of E coli were identified out of 96 culture positive specimens of urine and found sensitive to Vaccinium macrocarpon (p<0.000). Results revealed that Vaccinium macrocarpon has antibacterial effect against E coli. Furthermore the antibacterial activity of Vaccinium macrocarpon has dose response relationship. Acidic nature of Vaccinium macrocarpon due to its pH is not contributory towards its antibacterial effect. Vaccinium macrocarpon concentrate may be used in urinary tract infection caused by E coli.

    Lower urinary tract dysfunction is a common pediatric urological problem that is often associated with urinary tract infection. We determined the prevalence of a urinary tract infection history in children with lower urinary tract dysfunction and its association, if any, with gender, bowel dysfunction, vesicoureteral reflux and specific lower urinary tract conditions. We retrospectively reviewed the charts of children diagnosed with and treated for lower urinary tract dysfunction, noting a history of urinary tract infection with or without fever, gender, bowel dysfunction and vesicoureteral reflux in association with specific lower urinary tract conditions. Of the 257 boys and 366 girls with a mean age of 9.1 years 207 (33%) had a urinary tract infection history, including 88 with at least 1 febrile infection. A total of 64 patients underwent voiding cystourethrogram/videourodynamics, which revealed reflux in 44 (69%). In 119 of the 207 patients all infections were afebrile and 18 underwent voiding cystourethrogram/videourodynamics, which revealed reflux in 5 (28%). A urinary tract infection history was noted in 53% of girls but only 5% of boys (p infection history than patients with idiopathic detrusor overactivity disorder or primary bladder neck dysfunction (each p urinary tract dysfunction have a much higher urinary tract infection incidence than males. This association was most often noted for lower urinary tract conditions in which urinary stasis occurs, including detrusor underutilization disorder and dysfunctional voiding. Reflux was found in most girls with a history of febrile infections. Since reflux was identified in more than a quarter of girls with only afebrile infections who were evaluated for reflux, it may be reasonable to perform voiding cystourethrogram or videourodynamics in some of them to identify reflux.

    The Commission for Hospital Hygiene and Infection Prevention (KRINKO) updated the recommendations for the prevention of catheter-associated urinary tract infections in 2015. This article will describe the implementation of these recommendations in Frankfurt's hospitals in autumn, 2015. In two non-ICU wards of each of Frankfurt's 17 hospitals, inspections were performed using a checklist based on the new KRINKO recommendations. In one large hospital, a total of 5 wards were inspected. The inspections covered the structure and process quality (operating instructions, training, indication, the placement and maintenance of catheters) and the demonstration of the preparation for insertion of a catheter using an empty bed and an imaginary patient, or insertion in a model. Operating instructions were available in all hospital wards; approximately half of the wards regularly performed training sessions. The indications were largely in line with the recommendations of the KRINKO. Alternatives to urinary tract catheters were available and were used more often than the urinary tract catheters themselves (15.9% vs. 13.5%). In accordance with the recommendations, catheters were placed without antibiotic prophylaxis or the instillation of antiseptic or antimicrobial substances or catheter flushing solutions. The demonstration of catheter placement was conscientiously performed. Need for improvement was seen in the daily documentation and the regular verification of continuing indication for a urinary catheter, as well as the omission of regular catheter change. Overall, the recommendations of the KRINKO on the prevention of catheter-associated urinary tract infections were adequately implemented. However, it cannot be ruled out that in situations with time pressure and staff shortage, the handling of urinary tract catheters may be of lower quality than that observed during the inspections, when catheter insertion was done by two nurses. Against this background, a sufficient

This article will describe the implementation of these recommendations in Frankfurt’s hospitals in autumn, 2015.Material and methods: In two non-ICU wards of each of Frankfurt’s , inspections were performed using a checklist based on the new KRINKO recommendations. In one large hospital, a total of were inspected. The inspections covered the structure and process quality (operating instructions, training, indication, the placement and maintenance of catheters and the demonstration of the preparation for insertion of a catheter using an empty bed and an imaginary patient, or insertion in a model.Results: Operating instructions were available in all hospital wards; approximately half of the wards regularly performed training sessions. The indications were largely in line with the recommendations of the KRINKO. Alternatives to urinary tract catheters were available and were used more often than the urinary tract catheters themselves (15.9% vs. 13.5%. In accordance with the recommendations, catheters were placed without antibiotic prophylaxis or the instillation of antiseptic or antimicrobial substances or catheter flushing solutions. The demonstration of catheter placement was conscientiously performed. Need for improvement was seen in the daily documentation and the regular verification of continuing indication for a urinary catheter, as well as the omission of regular catheter change.Conclusion: Overall, the recommendations of the KRINKO on the prevention of catheter-associated urinary tract infections were adequately implemented. However, it cannot be ruled out that in situations with time pressure and staff shortage, the handling of urinary tract catheters may be of lower quality than that observed during the inspections, when catheter insertion was done by two

    Urinary tract infections (UTIs) are a common problem in the elderly population. The spectrum of disease varies from a relatively benign cystitis to potentially life-threatening pyelonephritis. This review covers the management of asymptomatic bacteriuria, acute uncomplicated cystitis, acute uncomplicated pyelonephritis, antibiotic resistance, catheter-associated bacteriuria/symptomatic UTIs, and antibiotic prophylaxis for recurrent infections in elderly men and women. Literature was obtained from English-language searches of MEDLINE (1966-April 2011), Cochrane Library, BIOSIS (1993-April 2011), and EMBASE (1970-April 2011). Further publications were identified from citations of resulting articles. Search terms included, but were not limited to, urinary tract infections, asymptomatic bacteriuria, acute uncomplicated cystitis, acute uncomplicated pyelonephritis, antibiotic resistance, catheter associated urinary tract infections, recurrent urinary tract infections, and elderly. The prevalence of UTIs in elderly women depends on the location in which these women are living. For elderly women living in the community, UTIs compromise the second most common infection, whereas in residents of long-term care facilities (LTCFs) and hospitalized subjects, it is the number one cause of infection. The spectrum of patient presentation varies from classic signs and symptoms in the independent elderly population to atypical presentations, including increased lethargy, delirium, blunted fever response, and anorexia. Although there are few guidelines specifically directed toward the management of UTIs in the elderly population, therapy generally mirrors the recommendations for the younger adult age groups. When choosing a treatment regimen, special attention must be given to the severity of illness, living conditions, existing comorbidities, presence of external devices, local antibiotic resistance patterns, and the ability of the patient to comply with therapy.

  6. Mechanisms of urinary tract sterility maintenance

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Physiologically, urine and the urinary tract are maintained sterile because of physical and chemical properties of urine and the innate immune system’s action. The urinary tract is constantly exposed to the invasion of microorganisms from the exterior environment, also because of the anatomical placement of the urethra, in the vicinity of the rectum. Particularly vulnerable to urinary tract infections (UTI are women (an additional risk factor is pregnancy, but also the elderly and children. The main pathogens causing UTI are bacteria; in 70-95% of cases it is the bacterium Escherichia coli. Infections caused by viruses and fungi are less common and are associated with decreased immunity, pharmacotherapy, or some diseases. Bacteria have evolved a number of factors that facilitate the colonization of the urinary tract: the cover and cell membrane antigens O and K1, lipopolysaccharide (LPS, fimbriae, pile and cilia. On the other hand, the human organism has evolved mechanisms to hinder colonization of the urinary tract: mechanisms arising from the anatomical structure of the urinary tract, the physicochemical properties of the urine and the activity of the innate immune system, also known as non-specific, which isolates and destroys pathogens using immunological processes, and the mechanisms for release of antimicrobial substances such as Tamm-Horsfall protein, mucopolysaccharides, immunoglobulins IgA and IgG, lactoferrin, lipocalin, neutrophils, cytokines and antimicrobial peptides. This review aims to analyze the state of knowledge on the mechanisms to maintain the sterility of the urinary tract used by the human organism and bacterial virulence factors to facilitate the colonization of the urinary tract.

    Streptococcus pneumoniae infections in children are most often lung infections or meningitis. Urinary tract infections are much rarer. We present the case of a urinary tract infection with Streptococcus pneumoniae. The clinical picture was classical. The urine culture showed the presence of Streptococcus pneumoniae in urine (10 4 UFC/mL; with 2 × 10 4 leucocytes/mL). The literature mentions a few cases of such infections. In some studies, the prevalence of Streptococcus pneumoniae in urine of children is less than 1%. Those children mostly present abnormalities of urinary tract. In our case, urinary ultrasound scan have shown the presence of an ectopic kidney in this child. The discussion between the clinician and the biologist has contributed to the discovery of this renal anomaly.

    2011-11-01

    Full Text Available Abstract Background Escherichia coli, the main bacteria found in recurrent urinary tract infections (UTI, is now frequently resistant to several currently used antibiotic treatments making new solutions essential. In this study, we evaluated the association propolis and proanthocyanidins type A to reduce bacterial anti-adhesion activity of E. coli on urothelial cells. Results This first double-blind, randomized, cross-over human trial included 5 volunteers that followed 6 different regimens with or without variable doses of cranberry and propolis with a washout period of at least 1 week between each regimen. Urine samples were collected at 0 h, 4-6 h, 12 h and 24 h after cranberry plus propolis or placebo capsule consumption. In vivo urinary bacterial anti-adhesion activity was assessed with a bioassay (a human T24 epithelial cell-line assay and an in vivo Caenorhabditis elegans model. HPLC-PDA-MS was used to detect propolis and cranberry compounds in urine. Bioassays indicated significant bacterial anti-adhesion activity in urine collected from volunteers who had consumed cranberry plus propolis powder compared to placebo (p E. coli strain presented a reduced ability to kill C. elegans after their growth in urine samples of patients who took cranberry plus propolis capsules. HPLC confirmed that propolis is excreted in urine. Conclusions This study presents an alternative to prevent recurrent UTI. Administration of PACs plus propolis once daily offers some protection against bacterial adhesion, bacterial multiplication and virulence in the urinary tract, representing an interesting new strategy to prevent recurrent UTI.

  13. Urinary tract infection in the neurogenic bladder

    2016-01-01

    There is a high incidence of urinary tract infection (UTI) in patients with neurogenic lower urinary tract function. This results in significant morbidity and health care utilization. Multiple well-established risk factors unique to a neurogenic bladder (NB) exist while others require ongoing investigation. It is important for care providers to have a good understanding of the different structural, physiological, immunological and catheter-related risk factors so that they may be modified when possible. Diagnosis remains complicated. Appropriate specimen collection is of paramount importance and a UTI cannot be diagnosed based on urinalysis or clinical presentation alone. A culture result with a bacterial concentration of ≥103 CFU/mL in combination with symptoms represents an acceptable definition for UTI diagnosis in NB patients. Cystoscopy, ultrasound and urodynamics should be utilized for the evaluation of recurrent infections in NB patients. An acute, symptomatic UTI should be treated with antibiotics for 5–14 days depending on the severity of the presentation. Antibiotic selection should be based on local and patient-based resistance patterns and the spectrum should be as narrow as possible if there are no concerns regarding urosepsis. Asymptomatic bacteriuria (AB) should not be treated because of rising resistance patterns and lack of clinical efficacy. The most important preventative measures include closed catheter drainage in patients with an indwelling catheter and the use of clean intermittent catheterization (CIC) over other methods of bladder management if possible. The use of hydrophilic or impregnated catheters is not recommended. Intravesical Botox, bacterial interference and sacral neuromodulation show significant promise for the prevention of UTIs in higher risk NB patients and future, multi-center, randomized controlled trials are required.

    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. 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. 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. 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.

    Congenital Anomalies of the Lower Urinary Tract (CALUT) are a family of birth defects of the ureter, the bladder and the urethra. CALUT includes ureteral anomalies such as congenital abnormalities of the ureteropelvic junction (UPJ) and ureterovesical junction (UVJ), and birth defects of the bladder and the urethra such as bladder-exstrophy-epispadias complex (BEEC), prune belly syndrome (PBS), and posterior urethral valves (PUV). CALUT is one of the most common birth defects and is often associated with antenatal hydronephrosis, vesicoureteral reflux (VUR), urinary tract obstruction, urinary tract infections (UTI), chronic kidney disease and renal failure in children. Here, we discuss the current genetic and molecular knowledge about lower urinary tract development and genetic basis of CALUT in both human and mouse models. We provide an overview of the developmental processes leading to the formation of the ureter, bladder, and urethra, and different genes and signaling pathways controlling these developmental processes. Human genetic disorders that affect the ureter, bladder and urethra and associated gene mutations are also presented. As we are entering the post-genomic era of personalized medicine, information in this article may provide useful interpretation for the genetic and genomic test results collected from patients with lower urinary tract birth defects. With evidence-based interpretations, clinicians may provide more effective personalized therapies to patients and genetic counseling for their families. PMID:23408557

  18. Recurrent uncomplicated urinary tract infections in women: a review.

    Science.gov (United States)

    Nosseir, Sandy B; Lind, Lawrence R; Winkler, Harvey A

    2012-03-01

    Recurrent urinary tract infections most often present with symptoms of irritative voiding. In most cases, they are caused by reinfection with a previously isolated organism. Patients with one or more symptoms of uncomplicated recurrent urinary tract infection should undergo thorough examination and screening for underlying comorbidities that increase susceptibility. When frequent reinfections, empiric treatment relapse, persistent infections, or risk factors for complicated infections are encountered, patients may benefit from urodynamics, cystoscopy, renal ultrasound, intravenous urogram, or voiding cystourethrogram to evaluate for anatomic, functional, or metabolic abnormalities affecting the urinary tract (e.g., stones, stricture, obstruction, vesicoureteral reflux, lesions, detrusor underactivity). These patients may benefit from culture-guided empiric treatment and further evaluation by urology, nephrology, or infectious disease specialists. In patients with a history of uncomplicated urinary tract infections, empiric treatment guided by local antimicrobial resistance may efficiently treat a suspected recurrence. After successful treatment of the acute infection, postcoital prophylaxis, continuous prophylaxis, or self-start empiric treatment may be selected based on frequency of recurrent infections, temporal relation to intercourse, and patient characteristics. Ancillary measures such as probiotics, cranberry products, or local estrogen replacement may also be considered. This article will review the current definition, epidemiology, pathogenesis, diagnosis, work-up, treatment, treatment side effects, and prevention of recurrent urinary tract infections in women. A suggested algorithm for evaluation and treatment based on current literature is provided.

    Full Text Available Introduction. Recurrent urinary tract infection is an actual problem of modern urology.Objective. Complex investigation of urinary tract infections including viral etiology for chronic recurrent cystitis in womenMaterials and methods. The study included 31 women with recurrent infection of urinary tract. Inclusion criteria were the presence of lower urinary tract symptoms caused by infection, severe recurrent course, the lack of anatomical and functional disorders of the urinary tract, the absence of bacterial pathogens during the study, taking into account the culture of aerobic and anaerobic culturing techniques.Results. The analysis of the clinical manifestations, the dominant in the study group were pain and urgency to urinate at 100% and 90% of women surveyed, respectively, and less frequent urination were recorded in 16.1% of patients. In general clinical examination of urine in all cases identified leukocyturia and 90% of the hematuria. By using a polymerase chain reaction (PCR in midstream urine of all examined was verified 10 types of human papilloma virus (HPV with the predominance of 16 and 18 types . Considering the presence of recurrent infectious and inflammatory processes of the urinary tract, cystoscopy with bladder biopsy was performed for all patients. When histomorphological biopsies of all patients surveyed noted the presence of the specific characteristics of HPV: papillary hyperplasia with squamous koilocytosis, pale cytoplasm and shrunken kernels. When analyzing the results of PCR biopsy data corresponded with the results of PCR in midstream urine in all biopsies was detected HPV.Conclusions. Human papillomavirus infection may be involved in the development of viral cystitis. In the etiological structure of viral cystitis, both highly oncogenic and low oncogenic HPV types can act.

    2015-10-01

    Historically, the incidence of genital and urinary tract (GU) injuries in major conflicts has been approximately 5%. To mitigate the risk of blast injury to the external genitalia, the United States and United Kingdom issued protective overgarments and undergarments to troops deployed in support of Operation Enduring Freedom. These two systems combined constitute the pelvic protection system (PPS). Our hypothesis was that PPS use is associated with a reduction of GU injuries in subjects exposed to dismounted improvised explosive device blast injuries. We identified two groups for comparison: those who were confirmed to have worn the PPS at time of injury (n = 58) and a historical control group who were confirmed as not wearing the PPS (non-PPS) (n = 61). Patients with any level of lower extremity amputation from dismounted improvised explosive device blast mechanism were included. The primary outcome measure was presence of a GU injury on admission. A univariate analysis assessing the strength of association with odds ratios and 95% confidence intervals was performed between the PPS and non-PPS groups. Mean Injury Severity Score (ISS) was higher in the PPS versus the non-PPS group (26.1 vs. 19.3, p = 0.0012). Overall, 31% of the patients in the PPS group sustained at least one GU injury versus 62.3% in the non-PPS group. The odds ratio of sustaining a GU injury in the PPS group as compared with the PPS group is 0.28 (31% vs. 62.3%; 95 % confidence interval, 0.62-0.12; p future work should focus on improved efficiency.

    2014-03-01

    Clinically, host factors in the pathogenesis of urinary tract infection (UTI) may be considered as modifiable (eg, behaviors associated with increased risk of UTI, anatomic and functional problems of the urinary tract) and thus potentially amenable to a change in patient behavior or treatment approach, or as intrinsic and nonmodifiable host factors that neither the patient nor the clinician can influence (eg, gender and genetic influences associated with UTI). Although considering nonmodifiable host factors may be discouraging to patients and clinicians at present, some genetic associations have the potential for future predictive value and may interface with future treatments.

    2014-01-01

    Nosocomial urinary tract infections are a common complication in healthcare systems worldwide. A review of the literature was performed in June 2014 using the Medical Literature Analysis and Retrieval System Online (MEDLINE) database, through either PubMed or Ovid as a search engine, to identify publications regarding nosocomial urinary tract infections (NUTIs) definition, epidemiology, etiology and treatment.According to current definitions, more than 30% of nosocomial infections are urinary tract infections (UTIs). A UTI is defined 'nosocomial' (NUTI) when it is acquired in any healthcare institution or, more generally, when it is related to patient management. The origin of nosocomial bacteria is endogenous (the patient's flora) in two thirds of the cases. Patients with indwelling urinary catheters, those undergoing urological surgery and manipulations, long-stay elderly male patients and patients with debilitating diseases are at high risk of developing NUTIs. All bacterial NUTIs should be treated, whether the patient is harboring a urinary catheter or not. The length of treatment depends on the infection site. There is abundance of important guidance which should be considered to reduce the risk of NUTIs (hand disinfection with instant hand sanitizer, wearing non-sterile gloves permanently, isolation of infected or colonized catheterized patients). Patients with asymptomatic bacteriuria can generally be treated initially with catheter removal or catheter exchange, and do not necessarily need antimicrobial therapy. Symptomatic patients should receive antibiotic therapy. Resistance of urinary pathogens to common antibiotics is currently a topic of concern.

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

    In 2014 the Veterans Health Administration (VHA) of the Department of Veterans Affairs (VA) implemented a Virtual Breakthrough Series (VBTS) collaborative to help VHA facilities prevent hospital-acquired conditions: catheter-associated urinary tract infection (CAUTI) and hospital-acquired pressure ulcers (HAPUs). During the prework phase, participating facilities assembled a multidisciplinary team, assessed their current system for CAUTI or HAPU prevention, and examined baseline data to set improvement aims. The action phase consisted of educational conference calls, coaching, and monthly team reports. Learning was conducted via phone, web-based options, and e-mail. The CAUTI bundle focused on four key principles: (1) avoidance of indwelling urinary catheters, (2) proper insertion technique, (3) proper catheter maintenance, and (4) timely removal of the indwelling catheter. The HAPU bundle focused on assessment and inspection, pressure-relieving surfaces, turning and repositioning, incontinence management, and nutrition/hydration assessment and intervention. For the 18 participating units, the mean aggregated CAUTI rate decreased from 2.37 during the prework phase to 1.06 per 1,000 catheter-days during the action (implementation) phase (p model for implementing a virtual model for improvement.

    Urinary tract infections (UTIs) are amongst the most common bacterial infections affecting women. Although antibiotics are the treatment of choice for UTI, cranberry derived products have been used for many years to prevent UTIs, with limited evidence as to their efficacy. Our objective is to assess the efficacy of a cranberry extract capsule standardized in A-type linkage proanthocyanidins (PACs) for the prevention of recurrent urinary tract infection. We will perform a 1:1 randomized, controlled, double blind clinical trial in women aged 18 years or more who present ≥2 UTIs in 6 months or ≥ 3 UTIs in 12 months. One hundred and forty-eight women will be recruited and randomized in two groups to either receive an optimal dose of cranberry extract quantified and standardized in PACs (2 × 18.5 mg PACs per day) or a control dose (2 × 1 mg PACs per day). The primary outcome for the trial is the mean number of new symptomatic UTIs in women during a 6-month intervention period. Secondary outcomes are: (1) To evaluate the mean number of new symptomatic UTIs with pyuria as demonstrated by a positive leucocyte esterase test; (2) To detect the mean number of new symptomatic culture-confirmed UTIs; (3) To quantify urinary PACs metabolites in women who take a daily dose of 37 mg PACs per day compared to women who take a daily dose of 2 mg per day for 6 months; (4) To characterize women who present recurrent UTI based on known risk factors for recurrent UTI; (5) To describe the side effects of daily intake of cranberry extract containing 37 mg PACs compared to 2 mg PACs. This report provides comprehensive methodological data for this randomized controlled trial. The results of this trial will inform urologists, gynaecologists, family physicians and other healthcare professionals caring for healthy women with recurrent UTI, as to the benefits of daily use of an optimal dose of cranberry extract for the prevention of recurrent UTI.

    In 30% of children with urinary tract anomalies, urinary tract infection (UTI) can be the first sign. Failure to identify patients at risk can result in damage to the upper urinary tract. To provide recommendations for the diagnosis, treatment, and imaging of children presenting with UTI. The recommendations were developed after a review of the literature and a search of PubMed and Embase. A consensus decision was adopted when evidence was low. UTIs are classified according to site, episode, symptoms, and complicating factors. For acute treatment, site and severity are the most important. Urine sampling by suprapubic aspiration or catheterisation has a low contamination rate and confirms UTI. Using a plastic bag to collect urine, a UTI can only be excluded if the dipstick is negative for both leukocyte esterase and nitrite or microscopic analysis is negative for both pyuria and bacteriuria. A clean voided midstream urine sample after cleaning the external genitalia has good diagnostic accuracy in toilet-trained children. In children with febrile UTI, antibiotic treatment should be initiated as soon as possible to eradicate infection, prevent bacteraemia, improve outcome, and reduce the likelihood of renal involvement. Ultrasound of the urinary tract is advised to exclude obstructive uropathy. Depending on sex, age, and clinical presentation, vesicoureteral reflux should be excluded. Antibacterial prophylaxis is beneficial. In toilet-trained children, bladder and bowel dysfunction needs to be excluded. The level of evidence is high for the diagnosis of UTI and treatment in children but not for imaging to identify patients at risk for upper urinary tract damage. In these guidelines, we looked at the diagnosis, treatment, and imaging of children with urinary tract infection. There are strong recommendations on diagnosis and treatment; we also advise exclusion of obstructive uropathy within 24h and later vesicoureteral reflux, if indicated. Copyright © 2014 European

    UTI is an infection that occurs in the urinary tract due to the proliferation of a microorganism. Female is fourteen times more vulnerable to UTI than male, because their urethra is shorter. Bladder epithelium is coated with a thin layer of glycosaminoglycans which act as a non-specific anti-adherence factor and nonspecific defense mechanisms against infection and can be found in the urine. An analytic study with cross sectional approach was conducted in 46 patients (23 with UTI and 23 non UTI) from June 2016 to determine differences in levels of urinary glycosaminoglycans between two groups. Urine samples were taken and tested for UTI and non UTI strips test. Laboratory examination of urine GAGs levels using ELISA kit for Human Glycosaminoglycans, then tabulated and analyzed using SPSS. The result showed no significant differences in the characteristics of women between two groups. There are significant differences in the mean levels of urinary GAGs in women with UTI compared with Non-UTI (69.74 ± 21.34; 21.39 ± 2.61 mg/l; p <0.001). There was no significant relationship between the sexual status and UTI incidence, with low odds ratio values and no significant difference in the mean of urinary glicosaminoglycans level based on sexual status.

    Lower urinary tract symptoms (LUTS) can frequently be seen in pregnant women. Pregnancy and delivery have been considered as risk factors in the occurrence of pelvic floor dysfunction and determinants of LUTS. The main associated risk factor is parity. In the present study, we aim to determine the frequency of LUTS and urinary incontinence (UI) during pregnancy and the associated risk factors. This prospective study was carried out in a total of 250 women during their 28- and 40-gestational week checks. The Urinary Distress Inventory-6, the Incontinence Impact Questionnaire-7, and International Consultation on Incontinence Questionnaire-Short Form were used to determine LUTS and its effect on quality of life. The mean age and gestational age of the participants were 29.41 ± 5.70 year (range 18-44) and 35.45 ± 2.98 weeks (range 28-40), respectively. The prevalence of LUTS was 81.6%. The prevalence of UI during pregnancy was 37.2%. Stress urinary incontinence, urge urinary incontinence and mixed urinary incontinence were diagnosed as 15.6, 4.8 and 16.8%, respectively. We found that advanced age, smoking and multiparity were risk factors associated with incontinence. Incontinence reduced pregnant women's quality of life. Lower urinary tract symptoms are commonly seen among pregnant women and these symptoms negatively affect the quality of life of pregnant women. Advanced age, smoking and multiparity were risk factors associated with urinary incontinence and LUTS. Obstetricians should be on the lookout for individual urological problems in pregnancy. Resolving any urological issues and cessation of smoking for the affected individuals will help alleviate the problem. © 2014 Wiley Publishing Asia Pty Ltd.

  12. Neuropeptides in Lower Urinary Tract (LUT) Function

    Science.gov (United States)

    Arms, Lauren; Vizzard, Margaret A.

    2014-01-01

    Numerous neuropeptide/receptor systems including vasoactive intestinal polypeptide, pituitary adenylate cyclase-activating polypeptide, calcitonin gene-related peptide, substance P, neurokinin A, bradykinin, and endothelin-1 are expressed in the lower urinary tract (LUT) in both neural and non-neural (e.g., urothelium) components. LUT neuropeptide immunoreactivity is present in afferent and autonomic efferent neurons innervating the bladder and urethra and in the urothelium of the urinary bladder. Neuropeptides have tissue-specific distributions and functions in the LUT and exhibit neuroplastic changes in expression and function with LUT dysfunction following neural injury, inflammation and disease. LUT dysfunction with abnormal voiding including urinary urgency, increased voiding frequency, nocturia, urinary incontinence and pain may reflect a change in the balance of neuropeptides in bladder reflex pathways. LUT neuropeptide/receptor systems may represent potential targets for therapeutic intervention. PMID:21290237

  13. Antimicrobial Stewardship and Urinary Tract Infections

    2014-05-01

    Full Text Available Urinary tract infections are the most common bacterial infections encountered in ambulatory and long-term care settings in the United States. Urine samples are the largest single category of specimens received by most microbiology laboratories and many such cultures are collected from patients who have no or questionable urinary symptoms. Unfortunately, antimicrobials are often prescribed inappropriately in such patients. Antimicrobial use, whether appropriate or inappropriate, is associated with the selection for antimicrobial-resistant organisms colonizing or infecting the urinary tract. Infections caused by antimicrobial-resistant organisms are associated with higher rates of treatment failures, prolonged hospitalizations, increased costs and mortality. Antimicrobial stewardship consists of avoidance of antimicrobials when appropriate and, when antimicrobials are indicated, use of strategies to optimize the selection, dosing, route of administration, duration and timing of antimicrobial therapy to maximize clinical cure while limiting the unintended consequences of antimicrobial use, including toxicity and selection of resistant microorganisms. This article reviews successful antimicrobial stewardship strategies in the diagnosis and treatment of urinary tract infections.

  14. Neural Control of the Lower Urinary Tract

    2015-01-01

    This article summarizes anatomical, neurophysiological, pharmacological, and brain imaging studies in humans and animals that have provided insights into the neural circuitry and neurotransmitter mechanisms controlling the lower urinary tract. The functions of the lower urinary tract to store and periodically eliminate urine are regulated by a complex neural control system in the brain, spinal cord, and peripheral autonomic ganglia that coordinates the activity of smooth and striated muscles of the bladder and urethral outlet. The neural control of micturition is organized as a hierarchical system in which spinal storage mechanisms are in turn regulated by circuitry in the rostral brain stem that initiates reflex voiding. Input from the forebrain triggers voluntary voiding by modulating the brain stem circuitry. Many neural circuits controlling the lower urinary tract exhibit switch-like patterns of activity that turn on and off in an all-or-none manner. The major component of the micturition switching circuit is a spinobulbospinal parasympathetic reflex pathway that has essential connections in the periaqueductal gray and pontine micturition center. A computer model of this circuit that mimics the switching functions of the bladder and urethra at the onset of micturition is described. Micturition occurs involuntarily in infants and young children until the age of 3 to 5 years, after which it is regulated voluntarily. Diseases or injuries of the nervous system in adults can cause the re-emergence of involuntary micturition, leading to urinary incontinence. Neuroplasticity underlying these developmental and pathological changes in voiding function is discussed. PMID:25589273

    When the terms funguria or fungal urinary tract infection are used, most physicians are referring to candiduria and urinary tract infections due to Candida species. Other fungi, including yeasts and molds can involve the kidney during the course of disseminated infection, but rarely cause symptoms referable to the urinary tract. Candida species appear to be unique in their ability to both colonize and cause invasive disease in the urinary tract. This overview focuses only on candiduria and Candida urinary tract infection because they are common and many times present perplexing management issues. Published by Elsevier Inc.

    While the association between scoliosis and cardiac and respiratory function impairments has been well characterized in clinical practice and research, the potential effect of scoliosis on urinary tract structure and renal function has received little attention. Therefore, the purpose of this study was to evaluate the preoperative clinical characteristics of urinary tract structure and renal function in pediatric patients with idiopathic scoliosis, using a combination of blood tests, urinalysis, and imaging. Preoperative measures of urinary tract structure and renal function were obtained for 16 patients, 13-17 years old, scheduled for corrective surgery for idiopathic scoliosis. Preoperative assessment included blood test and urinalysis, combined with structural imaging on ultrasound (US), magnetic resonance imaging (MRI), magnetic resonance urography (MRU), and radioisotope tracing (RI), using technetium-99 m mercaptoacetyltriglycine ( 99m Tc-MAG3). Differences in blood and urine tests between patients with and without urinary tract obstruction (UTO) were evaluated for significance using Mann-Whitney U test. For all 16 patients, blood tests and MRU were within normal limits. Dilatation of the renal pelvis was identified on US in eight patients (50.0%). UTO was identified on RI in six patients (37.5%). UTO was associated with elevated β2-microglobulin concentration. Urinary β2-microglobulin concentration >0.7 μg/mg Cr differentiated patients with UTO from those without UTO, with a sensitivity of 100% and specificity of 70%. β2-Microglobulin concentration may be a useful marker to screen for asymptomatic UTO in patients with idiopathic scoliosis. © 2016 Japan Pediatric Society.

There is always a demand for a biocompatible material to repair or substitute the urinary tract instead of using patient’s autologous tissues with its associated morbidity. Biomimetic approaches are tissue-engineering tactics aiming to tailor the material physical and biological properties to behave physiologically similar to the urinary system. This review highlights the different strategies to mimic urinary tissues including modifications in structure, surface chemistry, and cellular response of a range of biological and synthetic materials. The article also outlines the measures to minimize infectious complications, which might lead to graft failure. Relevant experimental and preclinical studies are discussed, as well as promising biomimetic approaches such as three-dimensional bioprinting.

    The aim of this study is to prove a relationship between urinary tract infection and malnutrition in children 0-3 years old, hospitalized in the IVI Pediatric Clinic, Hospital St. Mary Iaşi, between January 2000 and December 2004. We have made a retrospective study for 298 infant and young children with urinary tract infection, 237 eutrophic and 61 malnourished. We studied comparatively the both groups with urinary tract infection (UTI), and we applied statistic methods for results. The statistic methods prove that relative risk for UTI increases in malnutrition, predictive positive value is 72.5%. The clinical manifestation is similar in malnourished and eutrophic, but many co morbidities were associated with dystrophic status. Malformation of urinary tract was associate two times more in malnourished child. The etiology of infection was dominated by Escherichia coli, Proteus and Klebsiella pneumoniae. In malnourished children 5% of UTI was determinate by opportunist etiological agents like: Enterobacter, Enterococcus, Acinetobacter. More frequently, bacterium develops resistance of antibiotics like amino-penicilina, Trimethoprim and Cephalosporin. Accurate and fast diagnosis and treatment of UTI in infant and child with malnutrition is the best way for nutritional rehabilitation and prevention of serious consequence.

    About 1% of the newborns show abnormalities of the urinary tract, representing 25% of the antenatally detected malformations. Most of these urinary abnormalities are detected by prenatal ultrasound between the 14th and the 22nd week of gestation. Their outcome is determined during the first weeks of pregnancy and depends on the degree of renal impairment and the presence of associated extrarenal malformations. Establishing the outcome is often difficult, however it can be predicted by ultrasound and biochemistry of fetal urine. Prenatal management should consist in follow-up and careful organisation of the postnatal management of congenital uropathies. Every antenatally dilated urinary tract requires postnatal investigation. Postnatal ultrasound on the 3rd to 4th day of life is recommended for confirming or excluding urinary abnormalities. In case of persistence, ultrasound has to be completed by other radiologic methods. Voiding cystourethrography and/or nuclear renography allow to identify the origin of the observed abnormalities. Apart from a few situations needing immediate correction, surgical treatment is rarely indicated. The principal of postnatal management is prevention of urinary tract infections by antibiotic prophylaxis and a close follow-up until adulthood.

    In January 2015, the Centers for Disease Control and Prevention (CDC)/National Health Safety Network (NHSN) changed the definition of catheter-associated urinary tract infection (CAUTI). We evaluated the outcomes of a robust CAUTI prevention program when we performed surveillance using the old definition (before 2015) versus the new definition (after 2015). This is the first study to evaluate how the change in CDC/NHSN definitions affected the outcomes of a CAUTI reduction program. Baseline was from January 2012 to September 2014; the intervention period was from October 2014 to February 2016. Staff nurses were trained to be liaisons of infection prevention (Link Nurses) with clearly defined CAUTI prevention goals and with ongoing monthly activities. CAUTI incidence per 1000 catheter days was compared between the baseline and intervention periods, using the 2 definitions. With the new definition, CAUTIs decreased by 33%, from 2.69 to 1.81 cases per 1000 catheter days (incidence rate ratio [IRR] = 0.67; 95% confidence interval [CI]: 0.48-0.93; P definition, CAUTIs increased by 12%, from 3.38 to 3.80 cases per 1000 catheter days (IRR = 1.12; 95% CI: 0.88-1.43; P = .348). We aggressively targeted CAUTI prevention, but a reduction was observed only with the new definition. Our findings stress the importance of having a reasonably accurate surveillance definition to monitor infection prevention initiatives.

  3. Value of cystography in urinary tract infections.

    1976-01-01

    Fifty-one children with a bacteriologically proven urinary tract infection had both an intravenous urogram (IVU) and a micturating cystogram. The IVU was normal in 35. Only 6 of these children showed reflux in the cystogram, affecting 7 of the 70 ureters at risk. Since reflux on its own does not cause renal damage, which occurs only with super-added infection, detection of reflux is not important providing the urine is kept sterile. We suggest that cystography be deferred providing the IVU is normal until recurrent infections occur while under hospital care, and, with this policy this unpleasant and sometimes hazardous investigation could be avoided in many children with a single urinary tract infection.

    Infectious complications remain a major cause of morbidity and mortality among transplant recipients. Urinary tract infection (UTI) is the most common infectious complication in kidney transplant recipients with a reported incidence from 25% to 75%, varies widely likely due to differences in definition, diagnostic criteria, study design, and length of observation. We sought reviews the incidence and importance of urinary tract infection on graft survival, the microbiology with special emphasis on multidrug resistant microorganisms, the therapeutic management of UTI and the prophylaxis of recurrent UTI among solid organ transplant recipients, highlighting the need for prospective clinical trials to unify the clinical management in this population.

    To assess whether the orally administered combination of hyaluronic acid (HA), chondroitin sulfate (CS), curcumin and quercetin could be effective in preventing recurrent cystitis in postmenopausal women and whether its efficacy was conditioned by the concurrent use of local estrogen therapy. This was a prospective evaluation of 145 postmenopausal women consecutively recruited from the database of three different investigators. All women should have mild-to-moderate urogenital atrophy and a history of recurrent urinary tract infections (≥2 episodes within 6 months or ≥3 episodes within 12 months documented by positive urine cultures) during the last year. Patients were assigned to three different therapeutic regimens: the first group was treated only with vaginal estrogens, the second group only with HA, CS, curcumin and quercetin per os, and the third group was treated with HA, CS, curcumin and quercetin associated with local estrogens. We evaluated the number of patients with <2 infective episodes in the 6-month follow-up and <3 episodes in the 12-month follow-up (main aim definition) and the reduction of related symptoms through a Visual Analog Scale (VAS) and the Pelvic Pain and Urgency/Frequency (PUF) patient symptom scale. Student's t-test and chi-squared test were used for data analysis as appropriate. At 6-month follow up, the main aim rate was 8%, 11.1% and 25% in the three groups, respectively (p<0.05 compared to baseline only in group 3). Although the reduction in the number of recurrent episodes became significant in all groups at 1 year follow-up, the main aim rate was almost double in women receiving both local estrogens and oral therapy (group 3) compared to those receiving single treatments. The improvement of related symptoms was significant in all groups at 12-month follow-up. In postmenopausal women, the combination of HA, CS, curcumin and quercetin per os was effective in preventing recurrent urinary tract infections, especially if

    Of the chlamydia species that can cause infections in humans, C. trachomatis is responsible for lower urinary tract diseases in men and women. C. trachomatis infections are prevalent worldwide, but current research is focused on females, with the burden of disease and infertility sequelae considered to be a predominantly female problem. However, a role for this pathogen in the development of male urethritis, epididymitis, and orchitis is widely accepted. Also, it can cause complications such ...

    The vagina is a key anatomical site in the pathogenesis of urinary tract infection (UTI) in women, serving as a potential reservoir for infecting bacteria and a site at which interventions may decrease the risk of UTI. The vaginal microbiota is a dynamic and often critical factor in this pathogenic interplay, because changes in the characteristics of the vaginal microbiota resulting in the loss of normally protective Lactobacillus spp. increase the risk of UTI. These alterations may result fr...

    To assess children's body concepts about anatomy and physiology of the urinary tract, children drew pictures responding to the question 'Where do you believe urine comes from?' A total of 152 children in three groups were examined. 81 children were out-patients. Of these, 36 children were being seen for the first time and 45 children had previously undergone bladder and bowel group training. They were compared to 71 continent controls. Children were given a body silhouette, in which they drew their view of the urinary tract. Half of the children (52.6%) drew a bladder and other organs; nearly 43% drew a tube or other anatomically incorrect pictures. Significant differences were found for group and age. Children who had undergone the group training more often drew a bladder and other organs (80%). Correct pictures and pictures of bladder and other organs were more common from children aged 11-16 years. Children have subjective concepts of the urinary tract which do not follow actual anatomy and physiology. For medical interventions as well as any training programmes, it is essential to understand these concepts and provide instructions in a child-centred and developmentally adequate way.

    Uncomplicated Urinary tract infections are common in adult women across the entire age spectrum, with mean annual incidence of 15% and 10% in those aged 15-39 and 40-79 years, respectively. Urinary tract infection (UTI), with its diverse clinical syndromes and affected host groups, remains one of the most common but widely misunderstood and challenging infectious diseases encountered in clinical practice. Recurrent urinary tract infections (UTIs) present a significant problem for women and a challenge for the doctors who care for them. The diagnosis of uncomplicated UTI can be achieved best by a thorough assessment of patient symptoms with or without the addition of a urine dipstick test. Treatment should be based on the most recent guidelines, taking into account resistance patterns in the local community. The patient who suffers from recurrent UTIs can be treated safely and effectively with continuous antibiotic prophylaxis, post-coital therapy, or self-initiated treatment. This review article covers the latest trends in the management of recurrent UTI among women. Further research is needed regarding rapid diagnosis of UTI, accurate presumptive identification of patients with resistant pathogens, and development of new antimicrobials for drug-resistant UTI.

    2015-01-01

    Proteus mirabilis is a Gram-negative bacterium which is well-known for its ability to robustly swarm across surfaces in a striking bulls’-eye pattern. Clinically, this organism is most frequently a pathogen of the urinary tract, particularly in patients undergoing long-term catheterization. This review covers P. mirabilis with a focus on urinary tract infections (UTI), including disease models, vaccine development efforts, and clinical perspectives. Flagella-mediated motility, both swimming and swarming, is a central facet of this organism. The regulation of this complex process and its contribution to virulence is discussed, along with the type VI-secretion system-dependent intra-strain competition which occurs during swarming. P. mirabilis uses a diverse set of virulence factors to access and colonize the host urinary tract, including urease and stone formation, fimbriae and other adhesins, iron and zinc acquisition, proteases and toxins, biofilm formation, and regulation of pathogenesis. While significant advances in this field have been made, challenges remain to combatting complicated UTI and deciphering P. mirabilis pathogenesis. PMID:26542036

    Urinary tract infection (UTI) is the most common bacterial infection independent of age. It is also one of the most common causes of hospitalizations for infections among elderly people and the most common indication for antibiotic prescriptions in primary care. Both diagnostics and management of lower and upper urinary tract infections provide challenges in clinical practice due to their high prevalence and recurrence, and worldwide increase of antibiotic resistance. The clinical symptoms of UTI are often uncharacteristic or asymptomatic. The accurate diagnosis and early treatment are crucial due to risk of septicaemia and long-term consequences. Currently the diagnosis of urinary tract infection is based on the presence of clinical symptoms in combination with the results of nitrite strip test indicating the presence of bacteria in urine and semi-quantitative measurement of white blood cells count in urine. Although urine culture is the gold standard in UTI diagnostics it is both time-consuming and costly. Searching for novel biomarkers of UTI has attracted much attention in recent years. The article reviews several promising serum and urine biomarkers of UTI such as leukocyte esterase, C-reactive protein, procalcitonin, interleukins, elastase alpha (1)-proteinase inhibitor, lactofferin, secretory immunoglobulin A, heparin-binding protein, xanthine oxidase, myeloperoxidase, soluble triggering receptor expressed on myeloid cells-1, α-1 microglobulin (α1Mg) and tetrazolium nitroblue test (TNB).

    Urinary tract infections (UTI) are the most common bacterial infections involving lower (cystitis, prostatitis) or upper (pyelonephritis, renal abscess, perinephric abscess) urinary tract. Differentiation of complicated and uncomplicated UTI is usually based on the presence of structural or functional urinary tract abnormalities, which can increase the risk of treatment failure and development of serious complications. Factors that increase the risk are foreign bodies, stones, obstruction, neurogenic bladder, kidney transplantation, immunosuppression, and pregnancy. Complicated UTI includes a spectrum of conditions that increase the risk of treatment failure, as well as of serious complications such as bacteremia and sepsis, perinephric abscess, renal impairment and emphysematous pyelonephritis. To avoid the potentially devastating outcomes, appropriate diagnostic procedures, antibiotic and surgical treatment, and appropriate follow-up are required. The incidence of complicated UTI will grow in the future due to general aging of the population, increasing incidence of diabetes, and ever growing number of immunocompromised and immunosuppressed patients. It is of key importance to recognize complicated UTI on time, and treat it wisely and aggressively to reduce duration of the disease and the risk of antibiotic resistance.

    As shown by literature data, abdominal trauma in children is responsible for 14% of deaths, whereas in adults for 10%. Although abdominal traumas in children can be severe and lead to massive blood loss, most children die because of accompanying traumas of the thorax and head. It validates the surgical rule concerning abdominal traumas 'investigate aggressively, manage conservatively'. Posttraumatic injury of the urinary system is not frequent in children and its specificity (compared with adults), depends on greater susceptibility to external aggressive factors. Blunt trauma is the cause of renal parenchyma injury and acceleration/deceleration injury affects the excretory system and vessels. Extension mechanism is the cause of ureter avulsion and/or thrombus formation in stretched renal vessels- it is characteristic in children with non-accidental traumas. Bladder and urethra injuries are rare in children. During car accidents, a rupture of full bladder (seat belt injury) or bladder perforation by fractured bones of the pelvis is possible. We analyzed all hospitalizations of abdominal trauma in our surgical ward in the year 2004 (70 cases). Renal injuries were found in 6 children (8.6%). Thanks to five-year clinical experience of our hospital, on the average only 1-2 cases per annum needed operation. The management of renal injuries involves first of all conservative treatment. This publication has educational character and may serve as a valuable reminder of the useful knowledge in daily cooperation between the emergency room, radiology department and surgical ward. Based on available literature from recent few years, we quote suggested renal injuries classifications and procedures.This publication contains only images from our department of radiology archives. Clinical symptoms are often not appropriate for blunt abdominal traumas diagnosis. Owing to clinical status, which is difficult to interpret, fast and complete radiological diagnosis is necessary for

    Catheter-associated urinary tract infections (CAUTIs) are among the most common healthcare-associated infections. Antiseptic cleaning of the meatal area before and during catheter use may reduce the risk of CAUTIs. To undertake a systematic review of the literature and meta-analysis of studies investigating the effectiveness of antiseptic cleaning before urinary catheter insertion and during catheter use for prevention of CAUTIs. Electronic databases were searched to identify randomized controlled trials. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated and compared across intervention and control groups using DerSimonian-Laird random-effects model. Subgroup analyses were performed. Heterogeneity was estimated using the I 2 statistic. In total, 2665 potential papers were identified; of these, 14 studies were eligible for inclusion. There was no difference in the incidence of CAUTIs when comparing antiseptic and non-antiseptic agents (pooled OR 0.90, 95% CI 0.73-1.10; P=0.31), or when comparing different agents: povidone-iodine vs routine care; povidone-iodine vs soap and water; chlorhexidine vs water; povidone-iodine vs saline; povidone-iodine vs water; and green soap and water vs routine care (P>0.05 for all). Comparison of an antibacterial agent with routine care indicated near significance (P=0.06). There was no evidence of heterogeneity (I 2 =0%; P>0.05). Subgroup analyses showed no difference in the incidence of CAUTIs in terms of country, setting, risk of bias, sex and frequency of administration. There were no differences in CAUTI rates, although methodological issues hamper generalizability of this finding. Antibacterial agents may prove to be significant in a well-conducted study. The present results provide good evidence to inform infection control guidelines in catheter management. Copyright © 2016 The Healthcare Infection Society. Published by Elsevier Ltd.

    Background Intraprostatic inflammation has been associated with lower urinary tract symptom (LUTS) progression. However, prior studies used tissue removed for clinical indications, potentially skewing inflammation extent or biasing the association. We, therefore, evaluated inflammation and LUTS incidence and progression in men who underwent biopsy of the prostate peripheral zone irrespective of indication. Material and Methods We developed nested case-control sets in men in the placebo arm of the Prostate Cancer Prevention Trial who were free of clinical BPH and had a protocol-directed year 7 biopsy. Cases had baseline IPSS 75th percentile (N = 46) and controls had a slope 75th percentile (N = 46) and controls had a slope inflammation and mean extent (%) of tissue area with inflammation. Results Inflammation prevalence in low cases (64%) was similar to controls (66%), but higher in moderate (69%) and high (73%) cases (P-trend = 0.4). Extent did not differ across LUTS categories (P-trend = 0.5). For progression from IPSS inflammation (10.1% versus 4.6%, P = 0.06). Conclusion Peripheral zone intraprostatic inflammation is not strongly associated with LUTS incidence or progression. PMID:27325488

To investigate the association of patient and injury characteristics, as well as bladder management, with the occurrence of patient-reported, symptomatic urinary tract infection(s) UTI(s) in patients with chronic neurogenic lower urinary tract dysfunction (NLUTD). Tertiary urologic referral center. The patient database was screened for patients with chronic (>12 months) NLUTD who had presented between 2008 and 2012. Patient characteristics, bladder evacuation management, the annual number of patient-reported, symptomatic UTIs and the type of prophylactic treatment to prevent UTIs were collected. Binary logistic regression analysis was used to investigate the effects of the investigated risk factors on the occurrence of symptomatic UTI(s) and recurrent symptomatic UTIs (⩾3 annual UTIs). The data of 1104 patients with a mean NLTUD duration of 20.3±11.6 years were investigated. The evacuation method was a significant (P⩽0.004) predictor for the occurrence of symptomatic UTI and recurrent symptomatic UTIs. The greatest annual number of symptomatic UTIs was observed in patients using transurethral indwelling catheters, and the odds of experiencing a UTI and recurrent UTIs were increased more than 10- and 4-fold, respectively. The odds of a UTI or recurrent UTIs were also increased significantly (P⩽0.014) in patients using intermittent catheterization (IC). Botulinum toxin injections into the detrusor increased the odds of a UTI ~10-fold (P=0.03). The bladder evacuation method is the main predictor for symptomatic UTIs in individuals with NLUTD. Transurethral catheters showed the highest odds of symptomatic UTI and should be avoided whenever possible.

    Children with recurrent urinary tract infections (rUTI) often show no identifiable cause of their infections. Neutrophil gelatinase-associated lipocalin (NGAL) is known to be upregulated within the uroepithelium and kidney of patients with UTI and exhibits a localized bacteriostatic effect through iron chelation. We hypothesize that some patients with rUTI without an identifiable cause of their recurrent infections have locally deficient NGAL production. We therefore explored whether a lack of NGAL production may be a factor in the pathogenesis of rUTI. Patients seen in the urology clinic for rUTI who were tract, or other reasons that predispose to UTI, such as neurogenic bladder, the need for intermittent catheterization, or unrepaired posterior urethral valves. Control patients were healthy children enrolled from the emergency department with no history of UTI or renal dysfunction, normal urinalysis at the time of enrollment, and presenting no diagnosis associated with increased NGAL levels, such as acute kidney injury or infection. NGAL was measured by immunoblot. Fifteen cases and controls were enrolled. Median urinary NGAL levels were significantly decreased in rUTI patients compared with controls [15 (14-29) ng/ml vs 30 (27-61) ng/ml; p = 0.002)] Although comparatively diminished, measurable NGAL levels were present in all patients with rUTI. Urinary NGAL is significantly decreased in patients with compared with patients without rUTI. These data suggest that some patients with rUTI may be predisposed to UTI because of a relative local deficiency in urinary NGAL production.

    Although the association of urinary lithiasis and urinary tract malformation is not rare, their management poses challenges. The aim of this study was to evaluate the relationship between urolithiasis and malformations of the urinary system. There were 34 patients (19 males and 15 females) with a mean age of 4.8 years (range, 2 months to 14 years). All patients had urinary lithiasis with a urinary tract malformation. Abdominal pain was the most frequent clinical symptom (38%). Urinary infection was found in 7 patients (21%) and macroscopic haematuria was present in 10 patients (29%). The most frequent urinary tract malformations were megaureter (8 cases), uretero-pelvic junction obstruction (7 cases) and vesico-ureteric reflux (8 cases), but its malformative origin could not be confirmed. Treatment consisted of lithiasis extraction in 32 cases associated with specific treatment of the uropathy in 27 cases. Postoperative outcome was uneventful in all cases. In fact, urinary lithiasis and urinary tract malformation association is not rare. Indeed, 9-34% of urinary lithiasis are noted to be associated with urinary tract malformation. Positive diagnosis relies specifically on kidney ultrasound, intravenous urography, and urethrocystography. Treatment depends on the type of urinary tract malformation, localisation and size of the urinary lithiasis. In conclusion, urinary lithiasis and urinary tract malformation association is a frequent eventuality. Surgical intervention is the usual mode of treatment.

    The frequency of urinary tract infection before and during pelvic radiotherapy was studied prospectively in 172 patients who were not catherised and had not had instrumentation for at least 4 weeks prior to radiotherapy. The incidence of urinary tract infection prior to radiotherapy was 17% and a further 17% of patients develped a urinary tract infection during radiotherapy. Mid-stream specimens of urine (MSU) should be examined for infection on a weekly basis during pelvic radiotherapy not only to identify this additional 17% of patients but also to detect those patients who have persistent urinary tract infection in spite of treatment with appropriate antibiotics.

    Urinary tract infections are the most common outpatient infections, but predicting the probability of urinary tract infections through symptoms and test results can be complex. The most diagnostic symptoms of urinary tract infections include change in frequency, dysuria, urgency, and presence or absence of vaginal discharge, but urinary tract infections may present differently in older women. Dipstick urinalysis is popular for its availability and usefulness, but results must be interpreted in context of the patient's pretest probability based on symptoms and characteristics. In patients with a high probability of urinary tract infection based on symptoms, negative dipstick urinalysis does not rule out urinary tract infection. Nitrites are likely more sensitive and specific than other dipstick components for urinary tract infection, particularly in the elderly. Positive dipstick testing is likely specific for asymptomatic bacteriuria in pregnancy, but urine culture is still the test of choice. Microscopic urinalysis is likely comparable to dipstick urinalysis as a screening test. Bacteriuria is more specific and sensitive than pyuria for detecting urinary tract infection, even in older women and during pregnancy. Pyuria is commonly found in the absence of infection, particularly in older adults with lower urinary tract symptoms such as incontinence. Positive testing may increase the probability of urinary tract infection, but initiation of treatment should take into account risk of urinary tract infection based on symptoms as well. In cases in which the probability of urinary tract infection is moderate or unclear, urine culture should be performed. Urine culture is the gold standard for detection of urinary tract infection. However, asymptomatic bacteriuria is common, particularly in older women, and should not be treated with antibiotics. Conversely, in symptomatic women, even growth as low as 10 2 colony-forming unit/mL could reflect infection. Resistance is

    Urinary tract infections (UTI) are the second most common infection in geriatric population. This study investigated clinical findings, diagnostic approaches, complicating factors, prognosis, causative microorganisms and antimicrobial susceptibility in geriatric patients diagnosed with UTI. A total of 140 hospitalised patients with UTIs were evaluated within three years between January 2011-January 2015 at the Eskisehir Yunus Emre State Hospital. UTI diagnosed when there were systemic and urinary signs and symptoms and a positive dipstick test and urine culture result, leukocyte and CRP like serum parameters. Among the studied patients, 41.4% had urological diseases, 20.7% had diabetes mellitus and 19.2% had neurological diseases. The most common symptoms and signs were fever, dysuria nausea/vomiting, general condition impairment, pyuria, haematuria. The laboratory values for CRP, ESR and leukocyte count were 84 mg/dL, 56 mm/s and 11.9 (10^3μL), with mean values being determined. Among patients having a urinary catheter (17.1%), 27.9% had a history of UTI, while 29.3% had been hospitalised. Escherichia coli and Klebsiella pneumoniae were the most commonly identified microorganisms. The mean duration for hospitalisation was 7.6 days, while a 5% mortality rate was observed over the course of the disease. Because of the potential for serious complications and mortality, elderly patients with urinary tract infection, should receive immediate empirical treatment based on anamnesis, clinical evaluation and urinalysis and should be re-examined using results from cultures and antibiograms upon follow-up.

    The vagina is a key anatomical site in the pathogenesis of urinary tract infection (UTI) in women, serving as a potential reservoir for infecting bacteria and a site at which interventions may decrease the risk of UTI. The vaginal microbiota is a dynamic and often critical factor in this pathogenic interplay, because changes in the characteristics of the vaginal microbiota resulting in the loss of normally protective Lactobacillus spp. increase the risk of UTI. These alterations may result from the influence of estrogen deficiency, antimicrobial therapy, contraceptives, or other causes. Interventions to reduce adverse effects on the vaginal microbiota and/or to restore protective lactobacilli may reduce the risks of UTI.

    The aim of this study was to analyze what kind of urinary symptoms patients have before receiving treatment by radical prostatectomy (RP), and to evaluate their influence on urinary incontinence (UI). Between 2002 and 2012, 758 consecutive patients underwent RP for clinically localized prostate cancer (PCa). Surgery was carried out by open retropubic RP in 545 (73.1%) of patients and laparoscopic RP in 201 (27%) by 5 surgeons who were excluded from data collection and analysis. The following symptoms were collected from the last urological check-ups or pre-operative consultation and classified as: storage symptoms, voiding symptoms, post micturition symptoms, history of acute urinary retention, benign prostatic hyperplasia treatment, history of transurethral resection of the prostate (TURP). A total of 661 patients were included on analysis: 136 (20.6%) patients reported low urinary tract symptoms (LUTS), 162 (24.5%) were considered incontinent after RP, and 45 (33.1%) of them reported LUTS before surgery. Postprostatectomy urinary incontinence (PPUI) was significantly different in patients with LUTS (117 [22.3%] vs. 45 [33.1%], P=0.009). The presence of any LUTS influence significantly in the appearance of PPUI (OR=1.72 [95% CI: 1.14-2.6), P=0.01). TURP is independently influential in PPUI (OR=6.13 [95% CI: 1.86-20.18], P=0.003). A patient with LUTS before surgery has an increased risk of 70% or even 200% to suffer PPUI and a patient who received treatment by TURP is 6 times at higher risk of PPUI. In conclusion, patients with LUTS are likely to present PPUI. History of TURP is influential by itself over PPUI. A good preoperative consultation is important to assess continence status and to create realistic expectations to patients before RP.

    Full Text Available Congenital anomalies of the kidney and urinary tract (CAKUT occur at a frequency of 1 in 500 live births and are a common cause of renal insufficiency in childhood. CAKUT encompass a wide spectrum of malformations including anomalies of the kidney, collecting system, bladder and urethra. Most cases of CAKUT are sporadic and limited to the urinary tract, but some of them are syndromic or associated with positive family history. To understand the basis of human renal anomalies, knowledge of kidney and urinary tract development is necessary. This process is very complicated, requires precise integration of a variety of progenitor cell populations of diverse embryonic origins and is controlled by many factors at every stage of development. This review focuses on the genetic factors leading to developmental errors of important morphogenetic processes, particularly in metanephric kidney induction and ureteric bud branching. The essential results of genetic studies in regard to CAKUT, performed on experimental models and in humans, are presented. However, further investigations are required to complete understanding of the complex molecular network, which will help us to determine novel preventive and therapeutic strategies for CAKUT.

    Urinary tract infections are common infectious diseases which can occur in any part of the urinary tract such as bladder, kidney, ureters, and urethra. They are commonly caused by bacteria that enter through the urethra. Urinary tract infections commonly develop in the bladder and spread to renal tissues. Up to now, there are different antimicrobial agents which have beneficial role on urinary tract infections. However, most of them cause different adverse effects and therefore, much attention has been paid to the search for effective therapeutic agents with negligible adverse effects. Cranberry is known as one of the most important edible plants, which possesses potent antimicrobial effects against the bacteria responsible for urinary tract infections. Growing evidence has shown that cranberry suppresses urinary tract infections and eradicates the bacteria. Therefore, the aim of this study is to critically review the available literature regarding the antimicrobial activities of cranberry against urinary tract infection microorganisms. In addition, we discuss etiology, epidemiology, risk factors, and current drugs of urinary tract infections to provide a more complete picture of this disease.

    2015-03-01

    Full Text Available Congenital anomalies of the kidney and urinary tract are the commonest congenital anomalies in children, often detected prenatally with ultrasound. This method is useful for assesing the degree of dilatation of the collecting system, structure of the kidney parenchyma, amount of amniotic fluid and urinary bladder. Hydronephrosis is the most common among them. Anomalies can be bilateral or unilateral and different defects may coexist in an individual child. Anomalies of other organs and organ systems are often associated with anomalies of the kidneys and urinary tract, described in numerous syndromes. Congenital anomalies of the kidney and urinary tract can be divided in anomalies of the renal parencyma development, renal embryonic migration and position, cystic kidney diseases and anomalies of the urinary tract (collecting system of the kidneys, ureters, urinary bladder and urethra. They are the commonest cause of end-stage renal disease in children.

    Despite its proximity to the fecal flora, the urinary tract is considered sterile. The precise mechanisms by which the urinary tract maintains sterility are not well understood. Host immune responses are critically important in the antimicrobial defense of the urinary tract. During recent years, considerable advances have been made in our understanding of the mechanisms underlying immune homeostasis of the kidney and urinary tract. Dysfunctions in these immune mechanisms may result in acute disease, tissue destruction and overwhelming infection. The objective of this review is to provide an overview of the innate immune response in the urinary tract in response to microbial assault. In doing so, we focus on the role of antimicrobial peptides-a ubiquitous component of the innate immune response.

    1998-01-01

    Recently the diagnostic technique of magnetic resonance imaging (MRI) has developed rapidly, becoming one of the most effective methods of diagnosis, for urological disease, apart from ultrasonography (US) and computed tomography (CT). Nine patients with urinary tract obstruction were examined with a modified, heavily T2-weighted fast spine-echo pulse sequence (MR urography) between October, 1995, and August, 1997. Without the use of contrast medium we were able to discern urinary tract obstruction which could not be discerned by intravenous pyelography (IVP) or retrograde pyelography (RP). In conclusion, MR urography is able to provide fine details whilst reflecting renal function in cases of urinary tract obstruction which IVP and RP can not, for example a decrease in renal function, large prostatic hypertrophy, gross hematuria, lower ureteral tract disease, urinary diversion and urinary tract obstruction in children.

    Background Urinary tract infection (UTI) is an infection that affects part of the urinary tract. Ultrasound is a noninvasive test that can demonstrate the size and shape of kidneys, presence of dilatation of the ureters, and the existence of anatomic abnormalities. The aim of the study is to estimate the value of ultrasound in detecting urinary tract anomalies after first attack of UTI. Methods This study was conducted at the Nephrology Clinic, New Children's Hospital, Faculty of Medicine, Cairo University, from August 2012 to March 2013, and included 30 children who presented with first attack of acute febrile UTI. All patients were subjected to urine analysis, urine culture and sensitivity, serum creatinine, complete blood count, and imaging in the form of renal ultrasound, voiding cysto-urethrography, and renal scan. Results All the patients had fever with a mean of 38.96°C ± 0.44°C and the mean duration of illness was 6.23 ± 5.64 days. Nineteen patients (63.3%) had an ultrasound abnormality. The commonest abnormalities were kidney stones (15.8%). Only 2 patients who had abnormal ultrasound had also vesicoureteric reflux on cystourethrography. Sensitivity of ultrasound was 66.7%, specificity was 37.5%, positive predictive value was 21.1%, negative predictive value was 81.8%, and total accuracy was 43.33%. Conclusion We concluded that ultrasound alone was not of much value in diagnosing and putting a plan of first attack of febrile UTI. It is recommended that combined investigations are the best way to confirm diagnosis of urinary tract anomalies. © The Author(s) 2015.

    This review examines the evidence to date, analyzes specific risk factors and assesses the ability to prevent urinary incontinence in women, while providing clinical recommendations. More extraordinary risk factors such as ethnicity and race, mixed and fecal incontinence, iatrogenic and neurogenic factors should be discussed in a follow-up report. Studies have revealed that certain factors place women at risk for developing urinary incontinence, including age, obesity, diabetes, pregnancy and delivery, high-impact physical exercise factors and estrogen deficiency. Healthcare providers should screen women who are at risk for developing urinary incontinence and institute specific interventions, specifically behavioral and even rehabilitative techniques, to prevent this prevalent and distressing condition.

    The 2011 American Academy of Pediatrics (AAP) guidelines address imaging after initial febrile urinary tract infection (UTI) in infants >2 months of age. We sought to determine the frequency of upper urinary tract anomalies (hydronephrosis and vesicoureteral reflux (VUR)) in hospitalized premature infants with UTI. We retrospectively reviewed the electronic medical records of neonatal intensive care unit (NICU) admissions at a tertiary care children's hospital between 1 January 2006 and 31 December 2010. We queried the records for UTI, renal ultrasound (US) and voiding cystourethrogram (VCUG). We identified 3518 unique admissions. UTI occurred in 118 infants (3%). Sixty-nine (60%) had a normal US. Renal dilation was predominantly renal pelvic dilation (12%) and isolated caliectasis (22%). VUR was identified in 15 (14%) infants evaluated with a VCUG. VUR was identified in nine (12%) infants without and in seven (16%) with an abnormality on US. Reflux was identified in 7% of male and 38% of female infants with a UTI. Anatomic abnormalities of the upper urinary tract are uncommon in premature infants with a UTI that occurs during neonatal hospitalization. In concordance with the AAP guidelines, a VCUG may not be required in all NICU infants under age 2 months after a single UTI.

    Radioisotope scanning is very important in evaluation, diagnosis and proper treatment of urinary tract infection and vesico ureteral reflux because of high sensitivity of this technique and less radiation dose delivered to the patients. This is a descriptive cross-sectional study to determine the frequency vesico ureteral reflux in a group of children aged 28 days to 14 years referred to our department with diagnosis of urinary tract infection .The radioisotope scanning was conducted for all of patients (30 patients) and the results were analyzed. The results showed that urinary tract infection is seen in wide age group and is usually associated with vesico ureteral reflux . The above findings revealed the important role of radioisotope scanning in early diagnosis and subsequent treatment of urinary tract infection to detect vesico ureteral reflux and prevent subsequent side effects in these patients

    The most common source of nosocomial infection is the urinary tract, especially if they it is drained with a urethral catheter. Catheter-associated urinary tract infections account for at least 80% of all complicated urinary tract infections and are the most common type of hospital-acquired infection. Intestinal microflora plays the leading role in the pathogenesis of catheter-associated urinary tract infections, whereas the most important risk factor for their development is the long duration of urinary catheter drainage. In the case of short-term and intermittent catheterization, routine antibiotic prophylaxis is not required, but if a patient develops clinically significant infection, antibiotic therapy is required followed by definitive therapy based on culture. Urethral catheters coated with antimicrobial substances and anti-inflammatory agents can significantly reduce the adhesion and migration of bacteria, thereby reducing the incidence of urinary tract infections. Despite this, the incidence of catheter-associated infection remains high. We have reviewed recent literature related to catheter-associated urinary tract infections and the best means of preventing this condition.

    Endometriosis is defined as the presence of functional endometrial tissue outside the endometrial cavity and myometrium. Although this is a frequent disease with multifactorial causes, involvement of the lower urinary tract is rare. Magnetic resonance imaging is highly sensitive, specific and accurate in the diagnosis of endometriosis in the lower urinary tract, especially for allowing the identification of lesions obscured by adhesions or with subperitoneal extension. The present iconographic essay presents the main magnetic resonance imaging findings of the lower urinary tract involvement by endometriosis. (author)

    To identify risk factors for recurrent urinary tract infection (UTI) and renal scarring in children who have had 1 or 2 febrile or symptomatic UTIs and received no antimicrobial prophylaxis. This 2-year, multisite prospective cohort study included 305 children aged 2 to 71 months with vesicoureteral reflux (VUR) receiving placebo in the RIVUR (Randomized Intervention for Vesicoureteral Reflux) study and 195 children with no VUR observed in the CUTIE (Careful Urinary Tract Infection Evaluation) study. Primary exposure was presence of VUR; secondary exposures included bladder and bowel dysfunction (BBD), age, and race. Outcomes were recurrent febrile or symptomatic urinary tract infection (F/SUTI) and renal scarring. Children with VUR had higher 2-year rates of recurrent F/SUTI (Kaplan-Meier estimate 25.4% compared with 17.3% for VUR and no VUR, respectively). Other factors associated with recurrent F/SUTI included presence of BBD at baseline (adjusted hazard ratio: 2.07 [95% confidence interval (CI): 1.09-3.93]) and presence of renal scarring on the baseline (99m)Tc-labeled dimercaptosuccinic acid scan (adjusted hazard ratio: 2.88 [95% CI: 1.22-6.80]). Children with BBD and any degree of VUR had the highest risk of recurrent F/SUTI (56%). At the end of the 2-year follow-up period, 8 (5.6%) children in the no VUR group and 24 (10.2%) in the VUR group had renal scars, but the difference was not statistically significant (adjusted odds ratio: 2.05 [95% CI: 0.86-4.87]). VUR and BBD are risk factors for recurrent UTI, especially when they appear in combination. Strategies for preventing recurrent UTI include antimicrobial prophylaxis and treatment of BBD.

    We compared 2-year urinary incontinence and urgency scores of older women who attended a 2-hour bladder health class vs those who viewed a 20-minute abbreviated class video for the purpose of urinary incontinence prevention. A randomized, 2-arm, parallel design study was done to test the superiority of the 20-minute video over the 2-hour class. Outcomes at baseline, and 3, 12 and 24 months were the scores on questions 1 to 3 of ICIQ-SF (International Consultation on Incontinence Short Form) as the primary outcome and on IUSS (Indevus Urgency Severity Scale). Intent to treat analysis was done to compare the change from baseline in each intervention group across time and also with each other. Multiple imputation was used for missing data. A total of 647 women participated in the study. Mean age was 63 years and approximately 28% of the participants were African American, primarily from an urban setting. The 2 arms were balanced on body mass index at baseline, age, race/ethnicity, education, employment status, income and marital status. No differences in primary or secondary outcomes were demonstrated between the 2 groups from baseline to the 3, 12 or 24-month visits. The absence of significant differences in the outcome measures of ICIQ-SF and IUSS between the 2-hour class and the 20-minute video groups demonstrates that the 2 interventions were comparable. As urinary incontinence and urgency tend to rise annually in older women, instruction in bladder health self-care provided through either the 2-hour class or the 20-minute video format is a useful intervention to prevent urinary incontinence in older women.

    Full Text Available ABSTRACT: Lower urinary tract diseases (LUTD include different conditions that affect the urinary bladder, urethra and prostate. The objective of this study was to determine the frequency of different related diseases, to characterize the population affected, and to determine risk factors in dogs. The clinical cases were diagnosed with LUTD through physical examination, and clinical laboratory and imaging studies. Male dogs had a greater predisposition to present a LUTD. Dogs from 3 months to 18 years with a median of 8 years were affected, and the most affected breeds were Poodle, Labrador, German shepherd, Schnauzer, Cocker Spaniel and Chihuahua. The LUTD presented with the following frequencies: bacterial urinary tract infection 34.02%; micturition disorders 22.68%; urolithiasis 20.61%; prostatic disease 14.43%; traumatic problems 8.24%. Sixty-seven per cent of the cases were specific diseases, such as uncomplicated and complicated bacterial urinary tract infections, urinary retention of neurologic origin and silica urolithiasis.

    To explore the mismatch between functional bladder capacity and nocturnal urine production, and to study the pathophysiology of an increased nocturnal urine production in older patients with urinary incontinence. The present prospective observational study included adults aged ≥65 years with urinary incontinence. Participants completed questionnaires, frequency volume charts and renal function profiles. The nocturnal lower urinary tract symptom index was defined as nocturnal urine output/maximum voided volume; the nocturnal polyuria index as nocturnal/24 h urine output. The median age (n = 95) was 74 years (69-79), 87% were women and 73% had nocturnal lower urinary tract symptoms (nocturnal urinary incontinence or nocturia ≥2). Participants with nocturnal lower urinary tract symptoms had a significantly higher nocturnal urine output (809 mL vs 650 mL; P = 0.001) and no significant difference in maximum voided volume (350 mL vs 437 mL; P = 0.079) compared with participants without nocturnal lower urinary tract symptoms. Participants (nocturnal polyuria index >33% [n = 56], nocturnal polyuria index >40% [n = 42], nocturnal lower urinary tract symptom index >1.87 [n = 51]) showed higher night-time diuresis rates, free water and sodium clearance compared with during the daytime. Controls (nocturnal polyuria index ≤33% [n = 26], nocturnal polyuria index ≤40% [n = 40], nocturnal lower urinary tract symptom index ≤1.87 [n = 44]) had no circadian rhythm in their diuresis rate or sodium clearance, but more nocturnal free water clearance compared with during the daytime. The majority of older adults with urinary incontinence present nocturnal lower urinary tract symptoms. An increased nocturnal sodium diuresis seems to be the only mechanism differentiating patients with nocturnal lower urinary tract symptoms from controls. © 2017 The Japanese Urological Association.

Here we review the epidemiology, virulence mechanisms, and host response to the most frequently isolated Gram-positive uropathogens: Staphylococcus saprophyticus, Enterococcus faecalis, and Streptococcus agalactiae. We also review several emerging, rare, misclassified, and otherwise underreported Gram-positive pathogens of the urinary tract including Aerococcus, Corynebacterium, Actinobaculum, and Gardnerella. The literature strongly suggests that urologic diseases involving Gram-positive bacteria may be easily overlooked due to limited culture-based assays typically utilized for urine in hospital microbiology laboratories. Some UTIs are polymicrobial in nature, often involving one or more Gram-positive bacteria. We herein review the risk factors and recent evidence for mechanisms of bacterial synergy in experimental models of polymicrobial UTI. Recent experimental data has demonstrated that, despite being cleared quickly from the bladder, some Gram-positive bacteria can impact pathogenic outcomes of co-infecting organisms. When taken together, the available evidence argues that Gram-positive bacteria are important uropathogens in their own right, but that some can be easily overlooked because they are missed by routine diagnostic methods. Finally, a growing body of evidence demonstrates that a surprising variety of fastidious Gram-positive bacteria may either reside in or be regularly exposed to the urinary tract and further suggests that their presence is widespread among women, as well as men. Experimental studies in this area are needed; however, there is a growing appreciation that the composition of bacteria found in the bladder could be a potentially important determinant in urologic disease, including susceptibility to UTI.

    Guillain-Barré syndrome (GBS) as acute inflammatory demyelinating polyradiculoneuropathy frequently leads to lower urinary tract dysfunction. The available knowledge in the medical literature is limited and good recommendations for diagnosis and therapy are rare. In this study, 189 patients with GBS were screened for lower urinary tract dysfunction. In symptomatic patients, a urodynamic study was performed. Detrusor contractility, post-void residual, and changes of the symptoms over time were studied. Overall Barthel index and urinary control Barthel index as well as the relationship of time after onset of the disease and post-void residual were studied as possible screening criteria for urodynamic assessment. According to the urinary control Barthel index (BI), 115 of 189 patients (61%) presented lower urinary tract symptoms sometime during the course of disease. In 28 patients, these symptoms were temporary during the acute phase. At the time of urological assessment, 87 patients had lower urinary tract symptoms. At the end of rehabilitation, 37 had no symptoms anymore (BI 10), 20 were able to control micturition to a certain extent (BI 5), and 30 had no lower urinary tract control (BI 0). There was a significant negative correlation between post-void residual volume and overall BI (ρ -0.5823, p < 0.0001) and BI for urinary tract control (ρ -0.6430, p < 0.0001). Overall BI and BI for urinary tract control are suitable screening criteria for urodynamic assessment.

    The urinary tract infection is one of the most frequent bacterial infections in the childhood. Two hundred eleven children diagnosed as first febrile urinary tract infection patients were studied and performed Tc-DMSA renal scintigraphy in the acute phase of infection. The results were correlated to the duration and intensity of the fever before the diagnosis, to the acute phase reactants (hemogram, erythrosedimentation and reactive-C protein) and to the results of imaging studies (renal ultrasound and mictional uretrocystography)

    To determine age-stratified prevalence of concomitant bacterial meningitis in infants ≤60 days with a urinary tract infection, we performed a 23-center, retrospective study of 1737 infants with urinary tract infection. Concomitant bacterial meningitis was rare, but more common in infants 0-28 days of age [0.9%; 95% confidence interval (CI): 0.4%-1.9%) compared with infants 29-60 days of age (0.2%; 95% CI: 0%-0.8%).

    To describe and explore relationships among catheter problems in long-term indwelling urinary catheter users, including excess healthcare use for treating catheter problems. Long-term urinary catheter users experience repeated problems with catheter-related urinary tract infection and blockage of the device, yet little has been reported of the patterns and relationships among relevant catheter variables. Secondary data analysis was conducted from a sample in a randomised clinical trial, using data from the entire sample of 202 persons over 12 months' participation. Descriptive statistics were used to characterise the sample over time. Zero-inflated negative binomial models were employed for logistic regressions to evaluate predictor variables of the presence/absence and frequencies of catheter-related urinary tract infection and blockage. Catheter-related urinary tract infection was marginally associated with catheter blockage. Problems reported at least once per person in the 12 months were as follows: catheter-related urinary tract infection 57%, blockage 34%, accidental dislodgment 28%, sediment 87%, leakage (bypassing) 67%, bladder spasms 59%, kinks/twists 42% and catheter pain 49%. Regression analysis demonstrated that bladder spasms were significantly related to catheter-related urinary tract infection and sediment amount, and catheter leakages were marginally significantly and positively related to catheter-related urinary tract infection. Frequencies of higher levels of sediment and catheter leakage were significantly associated with higher levels of blockage, and being female was associated with fewer blockages. Persons who need help with eating (more disabled) were also more likely to have blockages. Catheter-related urinary tract infection and blockage appear to be related and both are associated with additional healthcare expenditures. More research is needed to better understand how to prevent adverse catheter outcomes and patterns of problems in

    2005-01-01

    Imaging in childhood urinary tract infection (UTI) is still a matter of debate. There are established guidelines, however new knowledge and the changed medical environment have enhanced this ongoing discussion. These new insights have impacted therapy and consequently the imaging algorithm. Modern imaging methods - particularly MRI and modern ultrasound (US) - are less invasive with a lower radiation burden. Additionally, it has been shown that VUR is a poor predictor for renal scarring out, which affects long-term results. Furthermore, the majority of UT malformations is depicted by prenatal US. The most crucial aspect of improving long-term outcome appears to be the early and reliable depiction of UTI and effective treatment to prevent renal scarring. This review tries to present this new knowledge and to discuss the potential of modern imaging. Recent changes in imaging algorithms are highlighted and an outcome-oriented algorithm that addresses these recent developments is proposed, without lightly abandoning established standards. It consists of an orienting US and - for depiction of renal involvement - amplitude coded color Doppler sonography or renal static scintigraphy (considered the gold standard, particularly for evaluating scars); in future MRI may play a role. Based on this concept, only patients with renal damage as well as patients with complex urinary tract malformations or intractable recurrent UTI may have to undergo VCUG. (orig.) [de

    2013-01-01

    Critical illness polyneuropathy is a frequent complication of critical illness in intensive care units. Reports on autonomic systems like lower urinary tract and bowel functions in patients with CIP are not available in medical literature. This study performed during primary rehabilitation of patients with critical illness polyneuropathy explores if sensory and motor pathways controlling the lower urinary tract function are affected from the disease. Neurourological examinations, urodynamics, electromyography and lower urinary tract imaging were performed in 28 patients with critical illness polyneuropathy. Sacral sensation was impaired in 1 patient (4%). Sacral reflexes were absent in 8 patients (30%). Anal sphincter resting tone was reduced in 3 (12%), anal sphincter voluntary contraction was absent or reduced in 8 patients (30%). Urodynamic findings were detrusor overactivity and detrusor overactivity incontinence in 9 (37.5%), incomplete voiding in 8 (30%), abnormal sphincter activity in 4 (16%), abnormal bladder sensation in 4 (16%) and detrusor acontractility in 2 patients (8.3%). Morphological abnormalities of the lower urinary tract had 10 patients (41.6%). Sensory and motor pathways controlling the lower urinary tract might be affected from CIP. During urodynamics dysfunctions of the storage as well as the voiding phase were found. Morphological lower urinary tract abnormalities were common.

    Full Text Available A 62-year-old male with past medical history of benign prostatic hyperplasia presented to the emergency department with complaints of decreased urinary flow, inability to fully empty his bladder, and gross hematuria. Physical examination was unremarkable. Urinalysis revealed large amount of blood and more than 700 white blood cells suggesting a urinary tract infection. Urine culture grew group D Salmonella greater than 100,000 colony-forming units per mL. He was prescribed 6 weeks of trimethoprim/sulfamethoxazole and had resolution of symptoms. Retrospectively, he reported a 3-day history of watery diarrhea about a week prior to onset of urinary symptoms that was presumed to be the hematogenous source in this case. Urinary tract infection from nontyphoidal Salmonella (NTS is rare and is usually associated with immunosuppression, chronic diseases, such as diabetes or structural abnormalities of the genitourinary tract. Genitourinary tract abnormalities previously reported in the literature that predispose to nontyphoidal Salmonella urinary tract infection include nephrolithiasis, chronic pyelonephritis, retrovesicular fistula, urethrorectal fistula, hydrocele, and post-TURP. We present an exceedingly uncommon case of 62-year-old male with group D Salmonella urinary tract infection predisposed by his history of benign prostatic hyperplasia.

    Prevalence of congenital abnormalities varies from 3.5% up to 43% in pediatrics.This wide interval is due to limited numbers of research. Limitation of data on recurrent urinary tract infection in CAKUT infants as well as symptoms which resemble other diseases makes it quite a challenge. A study of the prospective cohort was established to analyze the prevalence of recurrent UTI among CAKUT in children at Neonatal and Nephrology Paediatric Department of H.Adam Malik Hospital from 2016 to 2017.Urinalysis and urine culture were used to assess the presence of UTI. The result showed that the prevalence of UTI in CAKUT patients reached 64% in which 52% is the obstructive type and 12% non-obstructive type. Pelvic ureteric junction obstruction is the most common cause. Children with known urinary tract problems such as CAKUT are very prone to developing recurrent UTI. Due to a low survival rate of children with ESKD, new strategies are needed to prevent CAKUT, preserve renal function, and reduce associated cardiovascular morbidity. Meanwhile, children with CAKUT requires a multi-disciplinary and longer follow up.

  19. Role of scintigraphy in urinary tract infection

    Energy Technology Data Exchange (ETDEWEB)

    Conway, J.J.

    1988-10-01

    There is controversy regarding the role of radiological imaging for urinary tract infection (UTI). The gold standard has been the intravenous pyelogram (IVP). Yet, the IVP has a very limited value with only about 25% of children with pyelonephritis demonstrating abnormalities. Ultrasound (US) has recently been advocated as a replacement for the poorly sensitive and poorly specific IVP. However, comparative studies between US and IVP indicate only an equivalent sensitivity and specificity. Cortical scintigraphy with Technetium-99m glucoheptonate (99mTc GH) or 99mTc dimercaptosuccinic acid (99mTc DMSA) has also been advocated as a means of differentiating parenchymal (pyelonephritis) from nonparenchymal (lower UTI) involvement in UTI. The clinical presentation may be misleading especially in the infant and child in whom an elevated temperature, flank pain, shaking chills, or an elevated sedimentation rate are often lacking. The clinician attempts to localize the site of infection for it has a direct bearing upon the therapy. A collecting system infection can often be eradicated with a single oral dose of an appropriate antibiotic, whereas renal parenchymal involvement requires IV therapy for an extended interval. Cortical scintigraphy can localize the site of infection with a high degree of accuracy. Recent studies report a sensitivity of 86% and specificity of 81% of pyelonephritis. This is in contrast to the IVP with a sensitivity of only 24% and US with a sensitivity of only 42%. The scintigraphic appearance of parenchymal infection of the kidney is a spectrum of minimal to gross defects reflecting the degree of histologic involvement that spans from a mild infection to frank abscess. Cortical scintigraphy can be used to monitor the evolution of scarring following infection. Cortical scintigraphy with 99mTc DMSA or 99mTc GH is the method of choice for the initial evaluation of UTI. 37 references.

    2008-11-01

    A 70-year-old male who complained of urinary frequency and a feeling of incomplete emptying was admitted to our hospital. Imaging findings showed dilation of the left renal pelvis and ureter. He was diagnosed as having urinary tuberculosis because a positive urinary Mycobacterium tuberculosis result was obtained by polymerase chain reaction (PCR). He was treated with a combination of the antituberculosis agents isoniazid, rifampicin, pyrazinamide and ethambutol for six months. The symptoms and pyuria disappeared and M. tuberculosis was negative by PCR; however, Mycobacterium fortuitum was isolated by culture. Due to asymptomatic urinary tract infection by the multidrug resistant M. fortuitum, he was followed up with observation. Currently, he remains unchanged with regard to symptoms and imaging examination. M. fortuitum is a nontubercular mycobacterium, and clinical relevance between urinary tract infection and M. fortuitum has rarely emerged. However, we should be aware that nontubercular mycobacteria such as M. fortuitum can infect the urinary tract, especially in immunocompromised patients.

    The "Japanese Clinical Guideline for Female Lower Urinary Tract Symptoms," published in Japan in November 2013, contains two algorithms (a primary and a specialized treatment algorithm) that are novel worldwide as they cover female lower urinary tract symptoms other than urinary incontinence. For primary treatment, necessary types of evaluation include querying the patient regarding symptoms and medical history, examining physical findings, and performing urinalysis. The types of evaluations that should be performed for select cases include evaluation with symptom/quality of life (QOL) questionnaires, urination records, residual urine measurement, urine cytology, urine culture, serum creatinine measurement, and ultrasonography. If the main symptoms are voiding/post-voiding, specialized treatment should be considered because multiple conditions may be involved. When storage difficulties are the main symptoms, the patient should be assessed using the primary algorithm. When conditions such as overactive bladder or stress incontinence are diagnosed and treatment is administered, but sufficient improvement is not achieved, the specialized algorithm should be considered. In case of specialized treatment, physiological re-evaluation, urinary tract/pelvic imaging evaluation, and urodynamic testing are conducted for conditions such as refractory overactive bladder and stress incontinence. There are two causes of voiding/post-voiding symptoms: lower urinary tract obstruction and detrusor underactivity. Lower urinary tract obstruction caused by pelvic organ prolapse may be improved by surgery. © 2015 Wiley Publishing Asia Pty Ltd.

    Tubular adenomas in the urinary tract with the same appearance as those in the gastrointestinal tract have not yet been described in the literature. We herein report 4 cases of tubular adenomas in the urinary tract encountered within our consult practice. This lesion was defined by the presence of a collection of small round tubular glands with intestinal-type epithelium showing moderate dysplasia, identical to the histology of tubular adenomas in the intestinal tract. Patients ranged in age from 37 to 63 years (mean, 45 years), with 3 of the 4 being male (male-to-female ratio, 3:1). The locations were urinary bladder, prostatic urethra and ureter with hematuria, polyps, and obstructive mass as their presentations, respectively. One lesion was large measuring 1.4 cm associated with pseudoinvasion as well as invasive adenocarcinoma. Immunohistochemically, the tubular adenomas stained positive for CDX2 and CK20, while negative for GATA3 and CK7. One case showed positive nuclear β-catenin staining. Tubular adenoma of the urinary tract is a rare lesion, and recognition of this entity will encourage further reports and help to better understand the relation of tubular adenoma to concurrent and subsequent urinary tract malignancies.

    We review our outcomes and experience of artificial urinary sphincter implantation for patients with refractory urinary incontinence from different causes. Between April 2002 and May 2017, a total of 32 patients (median age, 40.8 years) with urinary incontinence had undergone artificial urinary sphincter placement during urinary tract reconstruction. Eighteen patients (56.3%) were urethral injuries associated urinary incontinence, 9 (28.1%) had neurogenic urinary incontinence and 5 (15.6%) were post-prostatectomy incontinence. Necessary surgeries were conducted before artificial urinary sphincter placement as staged procedures, including urethral strictures incision, sphincterotomy, and augmentation cystoplasty. The mean follow-up time was 39 months. At the latest visit, 25 patients (78.1%) maintained the original artificial urinary sphincter. Four patients (12.5%) had artificial urinary sphincter revisions. Explantations were performed in three patients. Twenty-four patients were socially continent, leading to the overall success rate as 75%. The complication rate was 28.1%; including infections (n = 4), erosions (n = 4), and mechanical failure (n = 1). The impact of urinary incontinence on the quality of life measured by the visual analogue scale dropped from 7.0 ± 1.2 to 2.2 ± 1.5 (P urinary sphincter implantation in our center are unique, and the procedure is an effective treatment as a part of urinary tract reconstruction in complicated urinary incontinence cases with complex etiology.

    We prospectively evaluated the association between adiposity and the risk of lower urinary tract symptoms incidence and progression in the Health Professionals Followup Study (HPFS). At baseline participants reported current height and weight, and weight at age 21 years. A year later they reported waist and hip circumferences, and every 2 years thereafter they reported weight. Participants periodically completed the International Prostate Symptom Score (I-PSS) and reported surgery or medication use for lower urinary tract symptoms. We used Cox proportional hazards regression to estimate the multivariable adjusted association between adiposity and lower urinary tract symptoms incidence and progression. The incidence analytical cohort of 18,055 men had no lower urinary tract symptoms at baseline. A total of 6,461 men entered the progression analytical cohort when they first experienced lower urinary tract symptoms. The risk of lower urinary tract symptoms in 4,088 cases increased with increasing body mass index (35 kg/m(2) or greater vs 23 to less than 25 HR 1.61, 95% CI 1.31-1.99), waist circumference (greater than 42 inches vs 33 or less HR 1.39, 95% CI 1.19-1.63) and weight gain since age 21 years (50 pounds or greater vs stable weight HR 1.31, 95% CI 1.17-1.46, each p trend symptom progression in 1,691 cases increased with body mass index (35 kg/m(2) or greater vs 23 to less than 25 HR 1.44, 95% CI 1.04-2.00, p trend symptoms develop or progress. Our findings support the notion that obesity may be an important target for lower urinary tract symptom prevention and intervention.

    2015-01-01

    A normal development of lower urinary tract function control evolves from involuntary bladder empting (incontinence) during infancy to daytime urinary continence, and finally a successful day and night continence that is generally achieved by the 5th to 7th year of age.This gradual process primarily depends on the progressive maturation of the neural control of the lower urinary tract, but it is also influenced by behavioral training that evolves through social support. Functional voiding disorders (bladder dysfunction) are common problems during childhood. They are present in 5-15 % of general pediatric population, and in one-fifth of school-age children or in over one-third of patients of the pediatric urologist or nephrologist. More than half of children with bladder dysfunction have vesicoureteral reflux, and more than two-thirds have recurrent urinary tract infections. There is also a frequent association of bladder dysfunction with constipation and encopresis (dysfunctional elimination syndrome). Bladder dysfunction may cause a permanent damage to the upper urinary tract and kidneys. In addition, urinary incontinence, as the most common manifestation of bladder dysfunction can be the cause of major stress in school- age children and have a negative effect on the child's feeling of self-esteem. Thus, a timely detection and treatment of this group of disorders in children is highly significant.

    Objective: To investigate the application value of three-dimensional reconstruction technique of multislice spiral CT(MSCT) in children urinary tract injuries. Methods: Forty-three patients with urinary tract injury performed MSCT scan, and three-dimensional reconstruction technique was used for volume rendering, maximum intensity projection and multi-planar reformation, urinary tract imaging was acquired completely. The images were reviewed by two experienced radiologists. Results: Of the 43 cases,there were 5 simple contusion of kidney, 5 contusion and laceration of kidney accompanied with subcapsular haematoma, 4 contusion and laceration of kidney accompanied with perinephric haematoma, 2 contusion and laceration of kidney accompanied with adrenal haematoma, 13 shattered kidney accompanied with extravasation of urine, 3 shattered kidney accompanied with renal pedicle injury, 6 shattered kidney accompanied with ureter injury, 2 pelvic fracture accompanied with posterior urethra split, 3 contusion of urinary bladder wall accompanied with blood clot in the urinary bladder.

  10. Development of the lower urinary tract and its functional disorders

    Directory of Open Access Journals (Sweden)

    Peco-Antić Amira

    2015-01-01

    Full Text Available A normal development of lower urinary tract function control evolves from involuntary bladder empting (incontinence during infancy to daytime urinary continence, and finally a successful day and night continence that is generally achieved by the 5th to 7th year of age. This gradual process primarily depends on the progressive maturation of the neural control of the lower urinary tract, but it is also influenced by behavioral training that evolves through social support. Functional voiding disorders (bladder dysfunction are common problems during childhood. They are present in 5-15 % of general pediatric population, and in one-fifth of school-age children or in over one-third of patients of the pediatric urologist or nephrologist. More than half of children with bladder dysfunction have vesicoureteral reflux, and more than two-thirds have recurrent urinary tract infections. There is also a frequent association of bladder dysfunction with constipation and encopresis (dysfunctional elimination syndrome. Bladder dysfunction may cause a permanent damage to the upper urinary tract and kidneys. In addition, urinary incontinence, as the most common manifestation of bladder dysfunction can be the cause of major stress in schoolage children and have a negative effect on the child’s feeling of self-esteem. Thus, a timely detection and treatment of this group of disorders in children is highly significant.

    Full Text Available Introduction. Among all the diseases of the urinary system, microbial-inflammatory lesions dominate, their prevalence is 29 per 1,000 of child population. Neurogenic bladder dysfunction leads to the chronicity and recurrence of urinary tract infections. Objective. To study the etiologic spectrum in children with urinary tract infection associated with neurogenic bladder dysfunction. Materials and methods. The study involved 434 children aged 4 to 15 years, who were hospitalized and out-patient treatment in Omsk from 2008 to 2014. Bacteriological urine culture on the microflora with determining the sensitivity to antibiotics was performed using Urin System Plus (Liofilchem, Italy. At the same time, the urine was examined for the presence of Cytomegalovirus, Herpes simplex virus I–II, Mycoplasma genitalium, Chlamydiae trachomatis, Ureaplasma urealyticum by polymerase chain reaction and enzyme immunoassay. Data processing was performed using Statistica 10.0 software package. Results. It was found that in the urine microbial landscape of children with urinary tract infection and neurogenic bladder dysfunction, Staphylococcus family dominated, unlike the spectrum of uropathogens in patirnts with urinary tract infection without functional obstruction, which is characterized by the predominance of Escherichia coli. The detection rate of cytomegalovirus in the urine indicates a significant decrease in the immunity of children with urinary tract infection and neurogenic bladder dysfunction. Conclusion. The shown differences in microbial landscape of the urine in urinary tract infection associated with neurogenic bladder dysfunction and without functional obstruction must be considered in the selection of an adequate therapy for patients of different groups, including immunocorrective approaches.

    This review provides an update on the risk of several important community-acquired infections seen in patients with diabetes: respiratory tract infections, urinary tract infections, and bacteremia. Respiratory tract infections: Recent epidemiological evidence shows a modest (1.25 to 1.75-fold) risk...... and tuberculosis. Limited data is available for diabetes and influenza, yet both influenza and pneumococcal vaccination is recommended in patients with diabetes. Urinary tract infections: The risk of asymptomatic bacteriuria and cystitis is 1.5 to 2 times increased in diabetes patients, while their risk...... factors for urinary tract infection are the same as in persons without diabetes. Bacteremia: The risk of bacteremia due to pneumococci is approximately 1.5 times increased in diabetes, similar to the increased risk for pneumonia. In comparison, diabetes is associated with 2.5 to 3 times increased risk...

  13. New paradigms of urinary tract infections: Implications for patient management

    2012-01-01

    Full Text Available Urinary tract infections (UTIs represent one of the most commonly acquired diseases among the general population as well as hospital in-patients, yet remain difficult to effectively and consistently treat. High rates of recurrence, anatomic abnormalities, and functional disturbances of the urinary tract all contribute to the difficulty in management of these infections. However, recent advances reveal important molecular and genetic factors that contribute to bacterial invasion and persistence in the urinary tract, particularly for the most common causative agent, uropathogenic Escherichia coli. Recent studies using animal models of experimental UTIs have recently provided mechanistic insight into the clinical observations that question the effectiveness of antibiotic therapy in treatment. Ultimately, continuing research will be necessary to identify the best targets for effective treatment of this costly and widespread infectious disease.

  14. Managing the urinary tract in spinal cord injury

    2010-01-01

    Full Text Available This review sets out to provide an overview of the author′s approach to the management of the urinary tract in the patient who has suffered from an injury to their spinal cord. Emphasis is given to the need to understand the fundamental pathophysiological patterns that are seen with injuries that involve the sacral segments of the cord (the conus and those that spare the conus but interrupt communication between the sacral parasympathetic and somatic centers and the brain (supraconal lesions. The importance of patient participation in management decisions is highlighted by considering the different ways in which the urinary tract can be managed and how the clinician needs to try to meet patient expectations and requirements while establishing safe urological management. Finally, consideration is given to the importance of establishing an appropriate follow up regime and managing urinary tract complications effectively.

    Full Text Available Introduction. Catheter-associated urinary tract infections (CAUTI are the most common nosocomial infections. The worldwide data show the increasing resistance to conventional antibiotics among urinary tract pathogens. Aim. To evaluate the adequacy of initial antimicrobial therapy in relation to the antimicrobial resistance of pathogens responsible for CAUTI in Clinical Center of Banja Luka. Methods. A retrospective study on major causes of CAUTI, antibiotic resistance and treatment principles was conducted at four departments of the Clinical Center of Banja Luka from January 1st, 2000 to April 1st, 2003. Results. The results showed that 265 patients had developed CAUTI. The seven most commonly isolated microorganisms were, in descending order: E. coli (31.0%, Pseudomonas aeruginosa (13.8%, Proteus mirabilis (12.9%, Gr. Klebsiella-Enterobacter (12.3%, Enterococcus spp. (5.2%, Pseudomonas spp. (4.3%, Serratia spp. (4.0%. The most common pathogens were highly resistant to ampicillin (64−100%, gentamycin (63−100%, and trimethoprim-sulfamethoxazole (68−100%, while some bacterias, like Pseudomonas aeruginosa and Serratia spp. showed rates of ciprofloxacin resistance as high as 42.8% and 72.7%, respectively. In 55.5% of the cases, the initial antibiotic therapy was inadequate, and was corrected latter on. There were no standard therapeutic protocols for this type of nosocomial infections. Conclusion. The results of this study emphasized an urgency of the prevention and introduction of clinical protocols for better management of CAUTI. Treatment principles should better correspond to the antibiotic sensitivity of uropathogens.

    To determine the frequency of constipation in patients with pediatric age group presenting with Lower Urinary Tract Symptoms (LUTS). Study Design: Descriptive study. Place and Duration of Study: Outpatient Department of Urology in Pakistan Kidney Institute at Shifa International Hospital, Islamabad, from November 2012 to February 2014. Methodology: Two hundred pediatric patients presenting with Lower Urinary Tract Symptoms (LUTS) were studied in terms of age, gender, obstructive and irritative types of LUTS along with any associated symptoms. Constipation was assessed by Bristol stool chart in these patients. Patients with exstrophy of bladder were excluded from the study. Descriptive statistics were measured for both qualitative and quantitative variables. For qualitative variables like gender, presenting symptoms, constipation and stool types, percentages and frequencies were calculated. For quantitative variables like age, percentages / mean ± SD were calculated. Results: Mean age was 6.87 ± 3.64 years with a range of 2 - 14 years. Constipation was found in 37.5% of the pediatric patients with lower urinary tract symptoms. Conclusion: Constipation is frequent and overlooked problem in pediatric patients having urinary symptoms. Irritative lower urinary tract symptoms are more common. Children up to 5 years of age are the most common sufferers. Knowing the burden of constipation in such patients can help physicians in better treatment of such cases. (author)

    Imaging is required in only a minority of patients with urinary tract infection. Some patients who present with severe loin pain are imaged because ureteric colic is suspected. If urinary tract infection does not respond normally to antibiotics, imaging is undertaken to check for evidence of renal obstuction or sepsis. Finally, after the acute infection has been treated, imaging is required in some patients to check for factors pre-disposing to renal damage or to relapsing or recurrent infection. This review discusses the appropriate choice of imaging technique to use in each clinical situation and summarises the expected findings. (orig.). With 15 figs., 1 tab.

    Stroke is an extremely common clinical entity, and poststroke incontinence is a major cause of morbidity for stroke survivors. Although patients can experience a wide variety of lower urinary tract symptoms, detrusor overactivity is among the most common clinical findings following stroke. All forms of lower urinary tract symptoms can negatively impact physical and psychosocial function for affected patients and their caregivers and loved ones. Careful evaluation is critical for successful management. Treatment is tailored to the goals and needs of each individual patient. Improvements in continence status can help to enhance overall and health-related quality of life. Copyright © 2017 Elsevier Inc. All rights reserved.

  2. Non-Antibiotic Prophylaxis for Urinary Tract Infections

    Directory of Open Access Journals (Sweden)

    Mariëlle Beerepoot

    2016-04-01

    Full Text Available Increasing antimicrobial resistance has stimulated interest in non-antibiotic prophylaxis of recurrent urinary tract infections (UTIs. Well-known steps in the pathogenesis of UTIs are urogenital colonization and adherence of uropathogens to uroepithelial cell receptors. To prevent colonization in postmenopausal women, vaginal, but not oral, estrogens have been shown to restore the vagina lactobacilli flora, reduce vaginal colonization with Enterobacteriaceae, and reduce the number of UTIs compared to placebo. Different lactobacilli strains show different results in the prevention of recurrent UTIs. Intravaginal suppositories with Lactobacillus crispatus in premenopausal women and oral capsules with Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 in postmenopausal women are promising. Ascorbic acid (vitamin C cannot be recommended for the prevention of UTIs. Cranberries are thought to contain proanthocyanidins that can inhibit adherence of P-fimbriated E. coli to the uroepithelial cell receptors. Cranberry products decreased UTI recurrences about 30%–40% in premenopausal women with recurrent UTIs, but are less effective than low-dose antimicrobial prophylaxis. However, the optimal dose of cranberry product has still to be determined. Initially OM-89, a vaccine with 18 heat-killed E. coli extracts, seemed promising, but this was not confirmed in a recently randomized trial.

    Seven patients have undergone urgent extracorporeal lithotripsy (UEL) for renal colics. 3 patients were cured. Before UEL they had insignificant defects of urodynamics and ureteral contraction. 3 patients with initial dilation of the upper urinary tracts > 2 cm and reflux ureteral motility, residual concrements eliminated spontaneously or after additional UEL procedures or combined treatment. One female with initial pelvic and uretral dilation and disturbed motility of the upper urinary tracts was treated for 6 months. 1-2.5-year follow-up detected neither concrements nor marked dilation of the calyceropelvic system. Patients with renal colics have more pronounced local defects of contraction rhythm and activity, peristaltic direction. Peristaltic disorders in the upper urinary tracts in patients with renal colics are local and may be related to acute occlusion and neuroreflex effects. This explains why UEL produces good results in renal colics, especially in patients with minimal defects of urodynamics. Complicated course after UEL early after the operation occurred in patients with dilated upper urinary tracts, high contraction amplitude registered by high tonicity of the ureteral wall and the presence of retrograde peristaltic waves.

    Functional disorders of the lower urinary tract as well as vesicoureteral reflux involved in the disease complex of urinary tract infection/permanent renal parenchymal damage can be considered predisposing or risk factors. Two main forms can be distinguished, i.e., unstable bladder and dysfunctional voiding, while transitional forms between the two exist. Functional disorders of the lower urinary tract obstruct spontaneous resolution of vesicoureteral reflux. They are found in about 50% of cases in all children with urinary tract infection and are associated with an increased risk of developing renal parenchymal scars. They are observed during the newborn period up to school age. In the first few months of life, particularly boys with bilateral high-grade reflux and congenital renal parenchymal damage are affected. At later ages girls are also affected, but in this age group bladder instability predominates. Incontinence as the leading clinical symptom appears in approximately 70% of all cases and is closely correlated with chronic constipation. Imaging procedures in addition to urodynamic methods are of decisive importance for diagnosis and treatment, but noninvasive approaches such as sonography should be given preference. (orig.) [de

    2015-12-01

    With the goal of better defining the types of bladder dysfunction observed in this population, we present the chief urologic complaints, results of urodynamic studies, and treatments of patients with dysautonomia-related urinary symptoms. All patients with dysautonomia referred to our neurourology clinic between 2005 and 2015 for management of lower urinary tract dysfunction were retrospectively reviewed. Each patient's chief urologic complaint was recorded and used to initially characterize the bladder storage or voiding symptoms. Patient evaluation included history and physical examination, urinalysis, post void bladder ultrasound, and urodynamic studies. Successful treatment modalities that subjectively or objectively improved symptoms were recorded. Of 815 patients with the diagnosis of dysautonomia, 82 (10 %) were referred for evaluation of lower urinary tract dysfunction. Mean age was 47 years (range 12-83) and 84 % were female. The chief complaint was urinary urgency ± incontinence in 61 % and hesitancy in 23 % of patients. Urodynamic findings demonstrated detrusor overactivity ± incontinence in 50 % of patients, although chief complaint did not reliably predict objective findings. Successful objective and subjective treatments were multimodal and typically non-operative. Lower urinary tract dysfunction may develop in at least 10 % of patients with dysautonomia, predominantly females. Bladder storage or voiding complaints do not reliably predict urodynamic findings. Urodynamically, most patients exhibited detrusor overactivity. The majority of patients were successfully managed with medical or physical therapy.

  3. The role of toll-like receptors (TLRs) in urinary tract infections (UTIs).

    Science.gov (United States)

    Behzadi, Elham; Behzadi, Payam

    2016-01-01

    Urinary Tract Infections (UTIs) are caused by different types of microbial agents such as uropathogenic Escherichia coli (UPEC) and Candida albicans. The presence of strong physical barriers may prevent the breach of pathogens into the urinary tract. However, sometimes the pathogenic microorganisms may pass through the barriers and stimulate the innate and adaptive responses. Among a variety of innate immune responses, Toll-Like Receptors (TLRs) are one of the most unique and interesting molecules regarding UTIs. Thus, the authors have focused their attention on the role of TLRs in urinary tract defense against pathogenic microbial agents such as UPEC and C.albicans through this literature review. Several papers regarding UTIs and TLRs including original and review articles were searched by PubMed and Google Scholar. They were studied and the most important aspects in association with the role of TLRs in UTIs were extracted. Additionally, this paper was prepared using the experience of the authors. The TLRs 2, 4 and 5 are the most functional molecules that contribute to urinary tract defense system and UTIs. It is incredible that TLRs are able to detect and recognize different parts of microbial components relating to the same pathogen. Besides, the flexibility of the TLR molecules may lead to identification of different types of microorganisms with different signaling pathways. Our knowledge associated with TLRs and their activities against microbial causative agents of UTIs may help us to prevent, control and treat UTIs at a higher quality level.

  4. Urinary Nerve Growth Factor Levels in Overactive Bladder Syndrome and Lower Urinary Tract Disorders

    Directory of Open Access Journals (Sweden)

    Hsin-Tzu Liu

    2010-12-01

    Full Text Available Overactive bladder (OAB is a syndrome based on self-reported symptoms of urgency and frequency with or without urge incontinence. Although urgency is the core symptom of OAB, patients might have difficulty to distinguish urgency from the urge to void. Urodynamic study is a useful diagnostic tool to discover detrusor overactivity (DO in patients with OAB; however, not all OAB patients have DO. Therefore, a more objective and non-invasive way to diagnose and assess OAB including DO is needed. Recent research has focused on urinary biomarkers in assessment of OAB. Urinary nerve growth factor (NGF level increases in patients with OAB-wet, bladder outlet obstruction, mixed urinary incontinence and urodynamic DO. Urinary NGF levels are correlated with severity of OAB symptoms. In patients with OAB and DO who have been well treated with antimuscarinics or botulinum toxin injection, urinary NGF levels have been shown to decrease significantly in association with reduction of urgency severity. However, not all patients with OAB have an elevated urinary NGF level. It might also be increased in patients with interstitial cystitis/painful bladder syndrome, cerebrovascular accident and lower urinary tract diseases such as urinary tract stone, bacterial infection and urothelial tumor. It is possible to use urinary NGF levels as a bio-marker for diagnosis of OAB as well as for the assessment of therapeutic outcome in patients with OAB or DO. Here, we review the latest medical advances in this field.

    Recurrent urinary tract infections (UTI) in patients with spinal cord injury are a frequent clinical problem. Often, preventive measures are not successful. We present the case reports of five patients with recurrent UTI who received additional homeopathic treatment. Of these patients, three remained free of UTI, whereas UTI frequency was reduced in two patients. Our initial experience with homeopathic prevention of UTI is encouraging. For an evidence-based evaluation of this concept, prospective studies are required.

    2016-02-01

    Urinary tract infections are common in the field of urogynaecology. Women with persistent urinary symptoms seem more likely to have bacteriuria despite negative cultures. In this review, we will give an overview of the recent insights on the relationship between urinary tract infection and persistent urinary symptoms and possible new therapeutic options. Recently published articles evaluated the prevalence of low-count bacteriuria (≥10 CFU/ml) or intracellular bacterial communities in women with overactive bladder symptoms (OAB). Differences in urinary microbioma observed in women with and without OAB symptoms were evaluated. In the light of these findings, current screening strategies were discussed and alternative screening methods for bacteriuria developed. Low-count bacteriuria (≥10 CFU/ml) seems to be more prevalent in women with OAB. Also intracellular bacterial communities are more commonly detected in these women. The microbioma found in women with urinary symptoms appeared to differ from healthy controls. The current screening methods might be insufficient as they are targeted at detecting uropathogenic Escherichia coli, mostly using a detection threshold of at least 10 CFU/ml and failing to detect intracellular bacterial communities. Studies evaluating the efficacy of treating women with low-count bacteriuria are limited but promising.

    Full Text Available Escherichia coli ordinarily resides in the lower gastrointestinal tract in humans, but some strains, known as Uropathogenic E. coli (UPEC, are also adapted to the relatively harsh environment of the urinary tract. Infections of the urine, bladder and kidneys by UPEC may lead to potentially fatal bloodstream infections. To survive this range of conditions, UPEC strains must have broad and flexible metabolic capabilities and efficiently utilize scarce essential nutrients. Whole-organism (or “omics” methods have recently provided significant advances in our understanding of the importance of metabolic adaptation in the success of UPECs. Here we describe the nutritional and metabolic requirements for UPEC infection in these environments, and focus on particular metabolic responses and adaptations of UPEC that appear to be essential for survival in the urinary tract.

    Catheter associated urinary tract infections are an essential measure for health care quality improvement that affects reimbursement through hospital acquired condition reduction programs in adult patients. With the mounting importance of preventing such infections we evaluated risk factors for acquiring catheter associated urinary tract infections in pediatric patients. All catheter associated urinary tract infections were identified at 1 pediatric institution from September 2010 to August 2014 from a prospective database maintained by the infection control office. To identify risk factors patients with a catheter associated urinary tract infection were individually matched to control patients with a urinary catheter but without infection by age, gender, date and the hospital location of the infection in 1:2 fashion. A total of 50 patients with catheter associated urinary tract infection were identified and matched to 100 control patients. Compared to controls the patients with infection were more likely to have a catheter in place for longer (2.9 days, OR 1.08, 95% CI 1.01, 1.15, p = 0.02). They were also more likely to be on contact precautions (OR 4.00, 95% CI 1.73, 9.26, p = 0.001), and have concurrent infections (OR 3.04, 95% CI 1.39, 6.28, p = 0.005) and a history of catheterization (OR 3.24, 95% CI 1.55, 6.77, p = 0.002). Using a conditional multivariate regression model the 3 most predictive variables were duration of catheter drainage, contact isolation status and history of catheterization. Longer duration of urinary catheter drainage, positive contact precautions status and a history of catheterization appear to be associated with a higher risk of catheter associated urinary tract infection in hospitalized pediatric patients. Physicians should attempt to decrease the duration of catheterization, especially in patients who meet these criteria, to minimize the risk of catheter associated urinary tract infection.

    occurred in patients that had the bladder catheter placed in the emergency department, before the admission to the internal medicine ward, which highlights the need to assess the urinary catheterization practices in those departments. The high rate of catheter associated urinary tract infection that occurred in the absence of bladder placement indication reinforces the need to implement prevention strategies that contemplate the reduction of its use. Emergency departments should be part of quality improvement projects in this area. Causes for the early onset of catheter associated urinary tract infection in this cohort should be investigated.

    Urinary Tract Infection is one of the commonest infections which affect humans. Half of all women have a UTI in their lifetime and one fourth have recurrent infections. Health behaviours can help patients to prevent Urinary Tract Infection recurrence and changing beliefs is necessary for health behaviour change. The aim of this study is to investigate the effect of education based on Health Belief Model on health beliefs of women with Urinary Tract Infection. This is a quasi-experimental study with pre-test and post-test design, conducted on 170 married women with Urinary Tract Infection, referred to selected hospital laboratories in Tehran. The laboratories were divided to experience and control groups. The data collection tool was a "self-administrated" questionnaire which was answered by samples of both groups, prior to the intervention and 12 weeks thereafter. The intervention (education based on Health Belief Model) was performed on the experiment group. Based on the study results, after the intervention the average score of the perceived susceptibility (Phealth behaviours (PHealth Belief Model was effective in promoting the health beliefs (except perceived barriers) and health behaviours of women with Urinary Tract Infection. Therefore, it can be suggested that the mentioned model can be used as one of the strategies for prevention of Urinary Tract Infection in women.

    Ayzac, Louis; Caillat-Vallet, Emmanuelle; Girard, Raphaële; Berland, Michel

    "RESEAU MATER" is useful to monitor nosocomial infections in maternity and contributes to the decreasing trend of it, since its implementation. Specifically, this network demonstrates its efficiency in the control of endometritis following vaginal deliveries, but not in the control of urinary tract infections. The aim of this study is to determine whether the difference between the control of endometritis and of urinary tract infection could be explained by an unsuitable regression model or by an unsuitable care policy concerning urinary cares. This study includes (1) the analysis of historic data of the network and (2) the description of French guidelines for maternity cares and available evaluations, concerning endometritis and urinary tract infection prevention. Univariate and multivariate odds ratios (ORs) were calculated for the total study period of 1999-2013, for these infections and their risk factors. The endometritis frequency is decreasing, in association with no significant evolution of associated risk factors, but urinary tract infection frequency is constant, in association with a increasing trend of its risk factors such as intermittent catheterization and epidural analgesia. In French guidelines, all preventive measures against endometritis are clearly broadcasted by all field operators, and repeated audits have reinforced the control of their application. But preventive measures against urinary tract infection seem to be broadcasted exclusively in the circle of infection prevention agencies and not in the obstetrics societies or in the Health Ministry communication. Urinary tract infection prevention requires a clearer public and professional policy in favor of a more efficient urinary cares, with a specific target to maternity.

    2016-01-01

    Urinary tract infection (UTI) is the most frequent disease for which patients seek medical care. The antimicrobial agents causing UTI and their sensitivity patterns have remarkably changed throughout the world over the past few years. Hence, the present study was designed to explore the uropathogens and their susceptibility to various molecules in our region. Methods: This descriptive cross sectional study was conducted at Medical C Unit of Ayub Teaching Hospital, Abbottabad from January 2015 to January 2016. Patients with clinical features of UTI were evaluated using Urine R/E and Urine culture and sensitivity. Ten antibiotics were checked for susceptibility. Results were analysed using SPSS 17. Results: A total of 630 patients presented with urinary complaints. Of these, 236 patients had more than 8-10 pus cells on urine R/E. They were further evaluated using culture and sensitivity and positive culture was obtained in 75 patients. Of these 34 (45.3%) were males and 41 (54.7%) were females. E Coli was the predominant isolate being present in 49 (65.3%) patients. This was followed by Klebsiella in 9 (12%) patients. Tazobactam-piperacillin and cefoperazone-sulbactam were the most sensitive drugs having overall sensitivity of 96% and 93.3% respectively. The isolates were highly resistant to Fluoroquinolones 77.3% followed by Penicillins 72% and TMP-SMX 69.3%.Conclusion: Antibiotic sensitivity patterns have enormously changed over the past decade. Newer agents are quite efficacious but their use should be highly judicious to prevent the development of resistance to these molecules. (author)

    Full Text Available Mohamed Abou El-Ghar, Huda Refaie, Doaa Sharaf, Tarek El-Diasty Radiology Department, Urology and Nephrology Center, Mansoura University, Mansoura, Egypt Abstract: For many years, intravenous urography (IVU was the modality of choice for diagnosing urinary tract abnormalities. IVU has many drawbacks including poor diagnostic accuracy in diagnosis and characterization of parenchymal lesions, also in cases of nonfunctioning kidneys. It has little diagnostic role to detect the cause of obstruction in absence of radio-opaque stones along the course of the urinary tract (UT. In the last two decades, with the era of the computed tomography (CT, CT has become the gold standard for diagnosis of urinary stones, while multiphasic CT urography (CTU has become the most useful diagnostic tool in different UT abnormalities including complex congenital anomalies, trauma, infection and tumors. Also, the “one-stop-shop” use of CTU in different anomalies including vascular, parenchymal, and urothelial evaluation has a great impact in management of patients. CT has many disadvantages over IVU including its high cost and the higher radiation dose but it is more effective than IVU. Keywords: CTU, IVU, urinary tract, obstruction, tumor, congenital

    Microbial drug resistance is a major problem in the treatment of infectious diseases worldwide. The purpose of this survey is to determine the prevalence of the type of bacterial agents that cause urinary infection and to assess the antimicrobial sensitivity pattern in the Urmia Medical University, Iran. In the period between 2005 and 2006, urine cultures collected were analyzed. Positive culture was defined as growth of a single bacterial species with colony count of > 100,000 CFU/mL. Stratification was done according to age-group and gender. Statistical tests used included chi-square to evaluate differences between susceptibility rates. A total of 803 urine culture positive patients were studied of whom 81.6% were females and 18.4% were males. The common micro-organisms isolated were E. coli (78.58%), Klebsiella (5.48%), Proteus and Staphylococcus. About 89% of the E. coli isolated showed sensitivity to cephtizoxin, 83.9% to gentamycin and 83.2% to ciprofloxacin; the highest resistance was shown to ampicillin and cotrimoxazole. Surveys of this nature will give a clear idea about the bacteriologic profile in a given institution as well their antibiotic sensitivity profile. This will act as a guide to commencing empirical antibiotic treatment in patients with urinary infections until such time culture reports are available. (author)

    Burkholderia cepacia is high virulent organism usually causing lower respiratory tract infections especially in Cystic fibrosis (CF) patients and post lung transplant. Urinary tract infections with Burkholderia cepacia have been associated after bladder irrigation or use of contaminated hospital objects. Post renal transplant urinary tract infection (UTI) is the most common infectious complications. Recurrent urinary tract infection with Burkholderia cepacia is a rare finding. Complete anatomical evaluation is essential in case recurrent urinary tract infections (UTI) after renal transplant. Vesico-ureteric reflux (VUR) and neurogenic urinary bladder was found to be important risk factors. (author)

    To report the outcomes of surgical management of urinary tract endometriosis. Retrospective study based on prospectively recorded data (NCT02294825) (Canadian Task Force classification II-3). University tertiary referral center. Eighty-one women treated for urinary tract endometriosis between July 2009 and December 2015 were included, including 39 with bladder endometriosis, 31 with ureteral endometriosis, and 11 with both ureteral and bladder endometriosis. Owing to bilateral ureteral localization in 8 women, 50 different ureteral procedures were recorded. Procedures performed included resection of bladder endometriosis nodules, advanced ureterolysis, ureteral resection followed by end-to-end anastomosis, and ureteroneocystostomy. The main outcome measure was the outcome of the surgical management of urinary tract endometriosis. Fifty women presented with deep infiltrating endometriosis (DIE) of the bladder and underwent either full-thickness excision of the nodule (70%) or excision of the bladder wall without opening of the bladder (30%). Ureteral lesions were treated by ureterolysis in 78% of the patients and by primary segmental resection in 22%. No patient required nephrectomy. Histological analysis revealed intrinsic ureteral endometriosis in 54.5% of cases. Clavien-Dindo grade III complications were present in 16% of the patients who underwent surgery for ureteral nodules and in 8% of those who underwent surgery for bladder endometriosis. Overall delayed postoperative outcomes were favorable regarding urinary symptoms and fertility. Patients were followed up for a minimum of 12 months and a maximum of 7 years postoperatively, with no recorded recurrences. Surgical outcomes of urinary tract endometriosis are generally satisfactory; however, the risk of postoperative complications should be taken into consideration. Therefore, all such procedures should be managed by an experienced multidisciplinary team. Copyright © 2017 AAGL. Published by Elsevier Inc

    Full Text Available Urinary tract infection (UTI is the second most common infection in humans after those involving the respiratory tract. This results not only in huge annual economic costs, but in decreased workforce productivity and high patient morbidity. Most infections are caused by uropathogenic Escherichia coli (UPEC. Antibiotic treatment is generally effective for eradication of the infecting strain; however, documentation of increasing antibiotic resistance, allergic reaction to certain pharmaceuticals, alteration of normal gut flora, and failure to prevent recurrent infections represent significant barriers to treatment. As a result, approaches to prevent UTI such as vaccination represent a gap that must be addressed. Our laboratory has made progress toward development of a preventive vaccine against UPEC. The long-term research goal is to prevent UTIs in women with recurrent UTIs. Our objective has been to identify the optimal combination of protective antigens for inclusion in an effective UTI vaccine, optimal adjuvant, optimal dose, and optimal route of delivery. We hypothesized that a multi-subunit vaccine elicits antibody that protects against experimental challenge with UPEC strains. We have systematically identified four antigens that can individually protect experimentally infected mice from colonization of the bladder and/or kidneys by UPEC when administered intranasally with cholera toxin (CT as an adjuvant. To advance the vaccine for utility in humans, we will group the individual antigens, all associated with iron acquisition (IreA, Hma, IutA, FyuA, into an effective combination to establish a multi-subunit vaccine. We demonstrated for all four vaccine antigens that antigen-specific serum IgG represents a strong correlate of protection in vaccinated mice. High antibody titers correlate with low colony forming units (CFUs of UPEC following transurethral challenge of vaccinated mice. However, the contribution of cell-mediated immunity cannot

    Full Text Available Uropathogenic Escherichia coli (UPEC is a causative agent in the vast majority of urinary tract infections (UTIs, including cystitis and pyelonephritis, and infectious complications, which may result in acute renal failure in healthy individuals as well as in renal transplant patients. UPEC expresses a multitude of virulence factors to break the inertia of the mucosal barrier. In response to the breach by UPEC into the normally sterile urinary tract, host inflammatory responses are triggered leading to cytokine production, neutrophil influx, and the exfoliation of infected bladder epithelial cells. Several signaling pathways activated during UPEC infection, including the pathways known to activate the innate immune response, interact with calcium-dependent signaling pathways. Some UPEC isolates, however, might possess strategies to delay or suppress the activation of components of the innate host response in the urinary tract. Studies published in the recent past provide new information regarding how virulence factors of uropathogenic E. coli are involved in activation of the innate host response. Despite numerous host defense mechanisms, UPEC can persist within the urinary tract and may serve as a reservoir for recurrent infections and serious complications. Presentation of the molecular details of these events is essential for development of successful strategies for prevention of human UTIs and urological complications associated with UTIs.

    Nephrogenic diabetes insipidus (NDI) is characterized by the kidney's inability to concentrate urine, which causes intense polyuria that may lead to urinary tract dilation. We report the morphological findings of the urinary tract in ten boys with NDI specifically addressing the presence and changes of urinary tract dilation during treatment. Patients were diagnosed at a median age of 1.6 years (range, 0.16-6.33 years) and treated with a low osmotic diet, hydrochlorothiazide-amiloride and indomethacin, which decreased the diuresis from a median of 10.5 ml/kg/h to 4.4 ml/kg/h (p < 0.001). Three patients showed normal renal ultrasound before treatment until last control, while the remaining seven showed urinary tract dilation. In this second group, dilation was reduced with treatment in four patients and disappeared in the remaining three. Children without dilation or in whom the dilation disappeared were diagnosed and treated earlier than those with persistent dilation (median 1.66 versus 4.45 years, respectively). After a median of 10.4 (range, 2.3-20.3) years of follow-up, no patients showed urological complications. Medical treatment of the disease improved the dilation in all cases, preventing its potential complications. Regardless of the good outcome of our patients, periodic urologic follow-up is recommended in NDI patients.

    There are few guidelines and little data on imaging after urinary tract infections in older children. We determined the clinical yield of renal and bladder ultrasound, and voiding cystourethrogram in older children and adolescents after urinary tract infection. We analyzed findings on voiding cystourethrogram, and renal and bladder ultrasound as well as the clinical history of patients who underwent the 2 studies on the same day between January 2006 and December 2010. We selected for study patients 5 to 18 years old who underwent imaging for urinary tract infection. Those with prior postnatal genitourinary imaging or prenatal hydronephrosis were excluded from analysis. We identified a cohort of 153 patients, of whom 74% were 5 to 8 years old, 21% were 8 to 12 years old and 5% were 12 to 18 years old. Of the patients 77% were female, 78% had a febrile urinary tract infection history and 55% had a history of recurrent urinary tract infections. Renal and bladder ultrasound findings revealed hydronephrosis in 7.8% of patients, ureteral dilatation in 3.9%, renal parenchymal findings in 20% and bladder findings in 12%. No patient had moderate or greater hydronephrosis. Voiding cystourethrogram showed vesicoureteral reflux in 34% of cases and bladder or urethral anomalies in 12%. Reflux was grade I, II-III and greater than III in 5.9%, 26% and 2% of patients, respectively. For any voiding cystourethrogram abnormality the sensitivity and specificity of any renal and bladder ultrasound abnormality were 0.49 (95% CI 0.37-0.62) and 0.76 (95% CI 0.66-0.84), respectively. Positive and negative predictive values were 0.58 (95% CI 0.44-0.71) and 0.69 (0.59-0.77), respectively. In older children with a history of urinary tract infection the imaging yield is significant. However, imaging revealed high grade hydronephrosis or high grade vesicoureteral reflux in few patients. Renal ultrasound is not reliable for predicting voiding cystourethrogram findings such as vesicoureteral

    2012-10-01

    Full Text Available Urinary tract infection (UTI is a common bacterial illness in children. Acute pyelonephritis in children may lead to renal scarring with the risk of later hypertension, preeclampsia during pregnancy, proteinuria, and renal insufficiency. Until now, vesicoureteral reflux (VUR has been considered the most important risk factor for post-UTI renal scar formation in children. VUR predisposes children with UTI to pyelonephritis, and both are associated with renal scarring. However, reflux nephropathy is not always acquired; rather, it reflects refluxassociated congenital dysplastic kidneys. The viewpoint that chronic kidney disease results from renal maldevelopment-associated VUR has led to questioning the utility of any regimen directed at identifying or treating VUR. Despite the recognition that underlying renal anomalies may be the cause of renal scarring that was previously attributed to infection, the prevention of renal scarring remains the goal of all therapies for childhood UTI. Therefore, children at high risk of renal scar formation after UTI should be treated and investigated until a large clinical study and basic research give us more information.

  12. Update on the approach of urinary tract infection in childhood.

    2015-01-01

    Urinary tract infection (UTI) is the most common bacterial infection in childhood. UTI may be the sentinel event for underlying renal abnormality. There are still many controversies regarding proper management of UTI. In this review article, the authors discuss recent recommendations for the diagnosis, treatment, prophylaxis, and imaging of UTI in childhood based on evidence, and when this is lacking, based on expert consensus. Data were obtained after a review of the literature and a search of Pubmed, Embase, Scopus, and Scielo. In the first year of life, UTIs are more common in boys (3.7%) than in girls (2%). Signs and symptoms of UTI are very nonspecific, especially in neonates and during childhood; in many cases, fever is the only symptom. Clinical history and physical examination may suggest UTI, but confirmation should be made by urine culture, which must be performed before any antimicrobial agent is given. During childhood, the proper collection of urine is essential to avoid false-positive results. Prompt diagnosis and initiation of treatment is important to prevent long-term renal scarring. Febrile infants with UTIs should undergo renal and bladder ultrasonography. Intravenous antibacterial agents are recommended for neonates and young infants. The authors also advise exclusion of obstructive uropathies as soon as possible and later vesicoureteral reflux, if indicated. Prophylaxis should be considered for cases of high susceptibility to UTI and high risk of renal damage. Copyright © 2015 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda.

    Urinary tract infections (UTI) are among the most common bacterial infections of humans. The mouse provides an excellent and tractable model system for cystitis and pyelonephritis caused by Escherichia coli and other uropathogens. Using a well-established model of experimental cystitis in which the bladders of female mice are infected via transurethral catheterization, the molecular details of the pathogenesis of bacterial cystitis have been substantially illuminated in the last decade. Uropathogenic E. coli attach to bladder epithelium (both in human and mouse) via adhesive type 1 pili, establish a replicative niche within epithelial cell cytoplasm, and form intracellular bacterial communities that are protected from antibiotic effects and immune clearance. The use of different inbred and mutant mouse strains offers the opportunity to study outcomes of infection, including resolution, formation of quiescent intracellular bacterial reservoirs, chronic bacterial cystitis, and recurrent infections. Urine, bladder, and kidney tissues can be analyzed by bacterial culture, histology, immunohistochemistry, immunofluorescent and confocal microscopy, electron microscopy, and flow cytometry, while a broad array of soluble markers (e.g., cytokines) can also be profiled in serum, urine, and tissue homogenates by ELISA, Western blotting, multiplex bead array, and other approaches. This model promises to afford continued opportunity for discovery of pathogenic mechanisms and evaluation of therapeutic and preventive strategies for acute, chronic, and recurrent UTI.

    2016-04-01

    Full Text Available Urinary tract infection (UTI is one of the most common infections of childhood. The clinical presentations are mostly non-specific or mild. As any episode of UTI can potentially damage the kidneys, timely diagnosis and treatment are necessary to prevent renal damage. Incidence of UTI varies depending on the age, gender, and race of the child. UTIs in children are commonly caused by bacteria, though viruses, fungi, and parasites are also occasionally involved. The pathogenesis of UTI is complex where several host and pathogen factors influence the course of the disease and its outcome. Urine culture is still considered the gold standard method for the diagnosis of UTI. The means of obtaining urine samples from children for culture involves urethral catheterisation and suprapubic aspiration. The conventional methods of antibiotic susceptibility testing are labour intensive and time exhaustive. With the advent of technology, many automated platforms are available which are rapid, involve less volume of the culture or the sample, and have high accuracy.

    2012-01-01

    Full text: Transitional cell carcinoma (TCC) is the most common urothelial neoplasm to involve the upper urinary tract and bladder. Prognosis significantly worsens with deeper invasion. The role of imaging is to detect the tiniest urothelial neoplasms while still potentially resectable and curable. In case of advance disease, imaging should identify the extent of disease. Intravenous or retrograde urography, ultrasonography, computed tomography or magnetic resonance imaging have been used for diagnosis of TCC. The diagnostic performances of these imaging modalities differ from each other. A recent review regarding imaging of TCC by Razavi et al states that the retrieved sensitivity/specificity for the detection of TCC of upper urinary tract for CT urography (CTU), MR urography, excretory urography, and retrograde urography were 96%/99%, 69%/97%, 80%/81%, and 96%/96%, respectively. For detecting bladder cancer, the retrieved sensitivity/specificity for CT cystography, MR cystography, and ultrasonography were 94%/98%, 91%/95%, and 78%/96%, respectively. They conclude that CT urography is the best imaging technique for confirming or excluding malignancy in the upper urinary tract, whereas CT cystography has the best diagnostic performance for diagnosing bladder cancer. While cystoscopy is still considered by most to be the gold-standard for evaluation of the urinary bladder, CTU is playing an increasing role in the detection of urinary bladder urothelial neoplasms. As with the upper urinary tract, bladder urothelial neoplasms typically present as a filling defect, a focal mass, or an area of abnormal focal wall thickening. Magnetic resonance imaging is superior for evaluation of the depth of tumour invasion into the bladder wall, but this knowledge may not ultimately affect treatment as feasibility for radical cystectomy depends on staging by a combination of clinical, histopathological and imaging findings. Radical cystectomy may include resection of adjacent organs

    2013-08-01

    Urinary tract infections (UTIs) are one of the most frequent clinical bacterial infections in women, accounting for nearly 25% of all infections. Around 50-60% of women will develop UTIs in their lifetimes. Escherichia coli is the organism that causes UTIs in most patients. Recurrent UTIs (RUTI) are mainly caused by reinfection by the same pathogen. Having frequent sexual intercourse is one of the greatest risk factors for RUTIs. In a subgroup of individuals with coexisting morbid conditions, complicated RUTIs can lead to upper tract infections or urosepsis. Although the initial treatment is antimicrobial therapy, use of different prophylactic regimens and alternative strategies are available to reduce exposure to antibiotics.

    Endoscopic injection of dextranomer/hyaluronic acid is an option for primary vesicoureteral reflux. Few groups have assessed the rate of urinary tract infection after dextranomer/hyaluronic acid injection. We reviewed our experience with dextranomer/hyaluronic acid injection, and determined the incidence of and risk factors for postoperative urinary tract infection. A retrospective cohort study was performed of all children with primary vesicoureteral reflux treated with dextranomer/hyaluronic acid from 2002 to 2007 at a single institution. Patient demographics and clinical outcomes were abstracted from the medical record. Risk factors for postoperative urinary tract infection, including female gender, preoperative vesicoureteral reflux grade, recurrent urinary tract infection, bladder dysfunction, nephropathy and persistent vesicoureteral reflux after surgery, were analyzed in a multivariate logistic regression model. We treated 311 children, of whom 87% were female and 13% were male (464 renal units), during the study period. Mode of presentation was urinary tract infection in 85% of cases. Mean followup was 2.6 years. Postoperatively urinary tract infection developed in 40 patients (13%) and febrile urinary tract infection developed in 11 (3.5%). Of patients with urinary tract infection 26 had initially negative postoperative voiding cystourethrogram, of whom 16 underwent repeat voiding cystourethrogram and 9 showed recurrent vesicoureteral reflux. Five of these 9 patients had clinical pyelonephritis. Of assessed risk factors only preoperative recurrent urinary tract infection (OR 2.2, p = 0.03) and bladder dysfunction (OR 3.3, p = 0.001) were independent predictors of post-injection urinary tract infection. In our series urinary tract infection after dextranomer/hyaluronic acid injection was rare. Patients with recurrent urinary tract infections and bladder dysfunction preoperatively are at increased risk for urinary tract infection after treatment. Patients

    2017-04-12

    Recommendations for the treatment of lower non-catheter-related urinary tract infection (UTI) in men are rarely evidence-based. Their management requires the localization of the site of infection, whether it be the urethra, bladder or prostate, and includes antibiotic therapy and in most cases urological assessment. They are often associated with urinary tract procedures or anatomical or functional abnormalities. Nearly 80 % of male UTIs are caused by Enterobacteriaceae. The prevalence of broad-spectrum beta-lactamase-producing strains (ESBL) and quinolone-resistant strains is increasing. The aim of this article is to define three types of lower, non-catheter-related UTI in men - urethritis, cystitis and prostatitis - their microbiology and management in Switzerland.

    2016-01-01

    Full Text Available Urinary tract infections (UTIs are among the commonest types of bacterial infections. The antibiotic treatment for UTIs is associated with important medical and economic implications. Many different microorganisms can cause UTIs though the most common pathogens are E. coli and members of family Enterobacteriaceae. The knowledge of etiology and antibiotic resistance pattern of the organisms causing urinary tract infection is essential. The present study was undertaken to evaluate trends of antibiotic susceptibility of commonly isolated uropathogens using newer antimicrobial agents, prulifloxacin, fosfomycin (FOM and doripenem. We conclude that maintaining a record of culture results and the antibiogram may help clinicians to determine the empirical and/or specific treatment based on the antibiogram of the isolate for better therapeutic outcome.

    Full Text Available Background: Urinary tract infections are a serious health problem affecting millions of people each year.They are the second most common type of infection in the body.The objective of study was to determine the etiology and antimicrobial susceptibility patterns of urinary tract infections pathogens isolated in our Patology Clinic laboratory. Materials and Methods: During the period July 2007- July 2008,were analysed 1422 urine samples.The determination of the total microbe load were acquire with an kit of the BIO-DETECTOR while the identification of germs with Apy sistem. Antibiotic susceptibility tests were assaied with the ATB UR strip. Results: About the total of samples analysed, 320 (22% had significant bacteriuria. Escherichia coli was the most common etiologic agent isolated (62%, followed by Klebsiella ssp. (10%, Pseudomonas aeruginosa (5,95% and Proteus mirabilis (5%. Gram-positive bacteria accounted for only 7.32% , with prevalence of Staphylococcus ssp (5,32 and Enterococcus spp (2%. The most effective antibiotics for Gram- were: Imipenem, Amikacin, Ceftazidime and Cefotaxim, while for Gram+ were: Minocyclin,Vancomycin and Oxacillin. Conclusion: Escherichia coli was the microrganism more frequently isolated between Gram negative bacteria with very susceptible to Amoxicillin. Currently, the empirical use of Cotrimoxazole and Amoxicillin is not recommended for Enterobacteriaceae. Urinary tract infections are more common in women than in men. Men are more likely to get a UTI once past the age of 65. Current data on the prevalence of multidrug resistance among urinary tract isolates should be a consideration to change the current empiric treatment of IVU.

    Full Text Available Abstract Introduction Pheochromocytomas are rare, potentially fatal, neuroendocrine tumors of the adrenal medulla or extra-adrenal paraganglia. Their clinical presentation varies greatly from the classic triad of episodic headache, diaphoresis and tachycardia to include a spectrum of non-specific symptomatology. Case presentation A 43-year-old Caucasian woman was referred to us from primary care services with a three-month history of recurrent urinary tract infections on a background of hypertension, latent autoimmune diabetes of adulthood and autoimmune hypothyroidism. At 38 years she required insulin therapy. Despite medication compliance and dietary control, she reported a recent history of increased insulin requirements and uncontrolled hypertension with concomitant recurrent urinary tract infections. A renal ultrasound examination, to rule out underlying renal pathology, revealed an incidental 8cm right adrenal mass of both solid and cystic components. A subsequent computed tomography of her abdomen and pelvis confirmed a solid heterogeneous mass consistent with a pheochromocytoma. There were no other features suggestive of multiple endocrine neoplasia. Urinary collection over 24 hours revealed grossly elevated levels of catecholamines and metabolites. Following an open right adrenalectomy, our patient's insulin requirements were significantly reduced and her symptoms resolved. Two weeks post-operatively, an iodine-131-metaiodobenzylguanidine scintigraphy was negative for residual tumor and metastatic disease. Urinary catecholamine and metabolite concentrations were within the normal range at a follow-up six months later. Conclusion Pheochromocytoma is a rare catecholamine-producing tumor requiring a high index of suspicion for early diagnosis. Our case report serves to highlight the importance of considering pheochromocytoma as a differential diagnosis in the atypical setting of recurrent urinary tract infections and concomitant autoimmune

    Urinary dysfunctions occur in the majority of MS patients and these patients are at higher risks of developing UTI due to multiple reasons. We determined to study the association between different urinary symptoms and UTI in MS patients. Eighty seven MS patients that referred to our medical care center with an acute attack of the disease, from November 2012 to April 2014, were included in the study. Patients were classified into two groups based on their urine culture results: UTI positive and non-UTI patients. The prevalence of different types of urinary symptoms was then compared among the two groups. The mean age of our patients was 36.8 years old. From the total 87 patients, 83 (95.4%) were female. Overall 56.3% of patients displayed urinary symptoms. The most prevalent urinary problems were urinary incontinence and frequency (25.3% and 24.1%, respectively). A positive urinary culture was seen in 71.3% of the patients. The prevalence of urinary problems was significantly higher in UTI patients in comparison to non-UTI patients (64.5% and 40% in UTI and non-UTI patients, respectively; p=0.036). Separately none of the different urinary symptoms displayed a significant difference between UTI and non-UTI patients (p>0.05). Not a single symptom can be diagnostic of UTI, but MS patient with urinary tract infections do present more urinary symptoms and this can be an indication for further urine analysis and screening measures for MS patients who display more urinary symptoms.

    Full Text Available This article reports the current evidence and expert opinions on diagnosis and management of neurogenic lower urinary tract dysfunction (NLUTD in Taiwan. The main problems of NLUTD are failure to store, failure to empty, and combined failure to store and empty. The priority of management of NLUTD should follow the order of: (1 preservation of renal function; (2 freedom from urinary tract infection (UTI; (3 efficient bladder emptying; and (4 freedom from indwelling catheter, and patients' expectation of management should be respected. Management of the urinary tract in patients with spinal cord injury (SCI or multiple sclerosis (MS must be based on urodynamic findings, rather than inferences from the neurologic evaluation. Selecting high risk patients is important to prevent renal function impairment in patients with chronic NLUTD. Patients with NLUTD should be regularly followed up for their lower urinary tract dysfunction by urodynamic study and any urological complication should be adequately treated. Avoiding a chronic indwelling catheter can reduce the incidence of developing a low compliant bladder. Antimuscarinic agents with clean intermittent catheterization (CIC may reduce urological complications and improve quality of life (QoL in patients with NLUTD. Intravesical injection of botulinum toxin A provides an alternative treatment for refractory detrusor overactivity (DO or low compliant bladder and can replace the need for bladder augmentation. When surgical intervention is necessary, we should consider the least invasive type of surgery and reversible procedure first and avoid any unnecessary surgery of the lower urinary tract. Keeping the bladder and urethra in a good condition without interference of the neuromuscular continuity provides patients with NLUTD a chance for future new technologies. It is most important to never give up on improving the QoL in patients with NLUTD.

    Full Text Available Background: Urinary tract infection, as a risk factor for adverse maternal and prenatal outcomes, is one of the most common bacterial infections during pregnancy. The objective of this study was to determine prevalence of urinary tract infection and its associated risk factors in pregnant women. Material and Methods: In a cross-sectional analytical study a total 2496 pregnant women who were underwent prenatal care through July 2011 in three rural and six urban health centers of Ardabil city, were selected by multistage sampling. Data collection was performed using a self designed questionnaire from women's prenatal care records, 240 pregnant women with positive urine culture were considered as a case group and the remaining as a control group. Data were analyzed through Kruskal – Wallis, Chi-square and Stepwise Logistic Regression statistical tests using SPSS version 16. Results: The incidence of urinary tract infection was 9.7%. Low socioeconomic status ( p=0.021, OR= 2/338, CI= 1/138-4/766,distance between pregnancies less than 3 years( p=0.026, OR= 2/137, CI= 1/093-4/141,and hyperemesis gravidarum( p=0.039, OR=2/06, CI= 1/038-4/098were determined as risk factors that significantly contribute to urinary tract infection in pregnant women. Conclusion: We conclude that appropriate distance between pregnancies, intensive care of pregnant women with low socioeconomic status and hyperemesis gravidarum may significantly prevent urinary tract infection and its related adverse health effects among pregnant women.

    2016-10-01

    The pelvic floor plays an integral part in lower urinary tract storage and evacuation. Normal urine storage necessitates that continence be maintained with normal urethral closure and urethral support. The endopelvic fascia of the anterior vaginal wall, its connections to the arcus tendineous fascia pelvis (ATFP), and the medial portion of the levator ani muscles must remain intact to provide normal urethral support. Thus, normal pelvic floor function is required for urine storage. Normal urine evacuation involves a series of coordinated events, the first of which involves complete relaxation of the external urethral sphincter and levator ani muscles. Acquired dysfunction of these muscles will initially result in sensory urgency and detrusor overactivity; however, with time the acquired voiding dysfunction can result in intermittent urine flow and incomplete bladder emptying, progressing to urinary retention in severe cases. This review will start with a discussion of normal pelvic floor anatomy and function. Next various injuries to the pelvic floor will be reviewed. The dysfunctional pelvic floor will be covered subsequently, with a focus on levator ani spasticity and stress urinary incontinence (SUI). Finally, future research directions of the interaction between the pelvic floor and lower urinary tract function will be discussed. Copyright © 2015 Elsevier B.V. All rights reserved.

    Cranberries (Vaccinium macrocarpon) have long been the focus of interest for their beneficial effects in preventing urinary tract infections. Among cranberry compounds, a group of proanthocyanidins (PACs) with A-type linkages were isolated which exhibit bacterial anti-adhesion activity against uropathogenic Escherichia coli strains. These PAC inhibit P-fimbriae synthesis and induce a bacterial deformation. This activity was demonstrated on both antibiotic susceptible and resistant bacteria. This review focused on the last discoveries in the knowledge of cranberry effects.

    Overactive bladder (OAB) is a syndrome based on self-reported symptoms of urgency and frequency with or without urge incontinence. Although urgency is the core symptom of OAB, patients might have difficulty to distinguish urgency from the urge to void. Urodynamic study is a useful diagnostic tool to discover detrusor overactivity (DO) in patients with OAB; however, not all OAB patients have DO. Therefore, a more objective and non-invasive way to diagnose and assess OAB including DO is needed. Recent research has focused on urinary biomarkers in assessment of OAB. Urinary nerve growth factor (NGF) level increases in patients with OAB-wet, bladder outlet obstruction, mixed urinary incontinence and urodynamic DO. Urinary NGF levels are correlated with severity of OAB symptoms. In patients with OAB and DO who have been well treated with antimuscarinics or botulinum toxin injection, urinary NGF levels have been shown to decrease significantly in association with reduction of urgency severity. However, not all patients with OAB have an elevated urinary NGF level. It might also be increased in patients with interstitial cystitis/painful bladder syndrome, cerebrovascular accident and lower urinary tract diseases such as urinary tract stone, bacterial infection and urothelial tumor. It is possible to use urinary NGF levels as a bio-marker for diagnosis of OAB as well as for the assessment of therapeutic outcome in patients with OAB or DO. Here, we review the latest medical advances in this field. Copyright © 2010 Formosan Medical Association & Elsevier. Published by Elsevier B.V. All rights reserved.

    To assess prevalence and severity of lower urinary tract function in 85-year-old men and women. Little is known on the prevalence of lower urinary tract dysfunction in this geriatric age group, which is now the fastest growing sector of the population worldwide. The Vienna Trans-Danube Aging study (VITA) is a longitudinal, population-based study initiated in 2000 that included men/women aged 75 years living in a well-defined area in Vienna. The main purpose of the VITA study was to identify risk factors for incident Alzheimer's disease. All study participants alive in 2010 were contacted by mail to complete a detailed questionnaire on various aspects of lower urinary tract symptoms (LUTS) and urinary incontinence (UI). The response rate was 68%, resulting in a total of 262 questionnaires available for analysis (men n= 96; women n= 166). All study participants were 85 years of age. Urinary incontinence defined as any involuntary loss during the past 4 weeks was reported by 24% of men and 35% of women (P= 0.04). Stress UI was more frequent in women (39%) than in men (14%, P 0.05). Nocturia more often than twice was more prevalent in men (69%) than in women (49%) (P= 0.02). Overactive bladder, according to International Continence Society criteria, was present in 55% of women and 50% of men. No difference regarding quality of life impairment as the result of LUTS and UI was noticed between sexes. A few co-morbidities were identified to correlate with UI and storage symptoms. These data provide insights into the prevalence and severity of LUTS and UI in individuals in their eighties, to our knowledge the largest population-based study in this age group. Demographic changes in upcoming decades underline the importance of a thorough understanding of lower urinary tract dysfunction in a geriatric population. © 2012 BJU INTERNATIONAL.

    Urinary dipsticks and culture analyses of a mid-stream urine specimen (MSU) at 10 5  cfu ml -1 of a known urinary pathogen are considered the gold standard investigations for diagnosing urinary tract infection (UTI). However, the reliability of these tests has been much criticised and they may mislead. It is now widely accepted that pyuria (≥1 WBC μl -1 ) detected by microscopy of a fresh unspun, unstained specimen of urine is the best biological indicator of UTI available. We aimed to scrutinise the greater potential of symptoms analysis in detecting pyuria and UTI. Lower urinary tract symptom (LUTS) descriptions were collected from patients with chronic lower urinary tract symptoms referred to a tertiary referral unit. The symptoms informed a 39-question inventory, grouped into storage, voiding, stress incontinence and pain symptoms. All questions sought a binary yes or no response. A bespoke software package was developed to collect the data. The study was powered to a sample of at least 1,990 patients, with sufficient power to analyse 39 symptoms in a linear model with an effect size of Cohen's f 2  = 0.02, type 1 error probability = 0.05; and power (1-β); 95% where β is the probability of type 2 error). The inventory was administered to 2,050 female patients between August 2004 and November 2011. The data were collated and the following properties assessed: internal consistency, test-retest reliability, inter-observer reliability, internal responsiveness, external responsiveness, construct validity analysis and a comparison with the International Consultation on Incontinence Modular Questionnaire for female lower urinary tract symptoms (ICIQ-FLUTS). The dependent variable used as a surrogate marker of UTI was microscopic pyuria. An MSU sample was sent for routine culture. The symptoms proved reliable predictors of microscopic pyuria. In particular, voiding symptoms correlated well with microscopic pyuria (χ 2  = 88, df = 1, p symptom inventory

    Objective diagnosis of symptomatic urinary tract infections in patients prone to asymptomatic bacteriuria is compromised by local host responses that are already present and the positive urine culture. We investigated interleukin-6 as a biomarker for nonfebrile urinary tract infection severity and diagnostic thresholds for interleukin-6 and 8, and neutrophils to differentiate between asymptomatic bacteriuria and urinary tract infection. Patients with residual urine and neurogenic bladders due to spinal lesions included in a long-term Escherichia coli 83972 asymptomatic bacteriuria inoculation trial were monitored for 2 years. Symptom scoring and urine sampling to estimate interleukin-6 and 8, and neutrophils were performed regularly monthly and at urinary tract infection episodes. Patients were followed in the complete study for a mean of 19 months (range 10 to 27) and those with asymptomatic bacteriuria with E. coli 83972 were followed a mean of 11 months (range 4 to 19). A total of 37 nonfebrile urinary tract infection episodes with complete data on interleukin-6 and 8, neutrophils and symptom scoring were documented. Interleukin-6 was the only marker that persistently increased during urinary tract infection compared to asymptomatic bacteriuria in pooled and paired intra-individual comparisons (p urinary tract infection symptoms (p urinary tract infection episodes. However, in urinary tract infections with worse symptoms interleukin-6 and neutrophils demonstrated equal good/excellent outcomes. Triggered interleukin-6 correlated to urinary tract infection symptom severity and demonstrated a promising differential diagnostic capacity to discriminate urinary tract infection from asymptomatic bacteriuria. Future studies should explore interleukin-6 as a biomarker of urinary tract infection severity and assess the treatment indication in nonfebrile urinary tract infections.

  20. Urinary tract infection in children: a review of its pathogenesis and risk factors.

    2000-12-01

    Urinary tract infection (UTI) is one of the commonest bacterial infections seen in children, ranking second only to those of the respiratory tract. A steady flow of urine, complete emptying of the bladder and various host defences provide the principal means of protection. Urinary stasis, on the other hand, provides an opportunistic environment for bacterial multiplication; several other factors also contribute to UTI, such as urinary obstruction, vesico-ureteric reflux (VUR) and other urinary tract malformations. UTI, especially in the presence of VUR, may lead to scarring of the kidney and progressive renal disease. It is vital, therefore, to diagnose such anomalies at an early stage, the overall aim being to identify those at high risk so that measures may be taken to prevent serious complications and preserve renal function. Those at low risk of UTI, however, should not be over investigated; this is in order to keep invasive procedures down to a minimum. Whenever possible, the management of high risk cases is best discussed between paediatrician, microbiologist, radiologist, urologist and the general practitioner.

  1. "Urinary Tract Infection"-Requiem for a Heavyweight.

    "Urinary tract infection" ("UTI") is an ambiguous, expansive, overused diagnosis that can lead to marked, harmful antibiotic overtreatment. "Significant bacteriuria," central to most definitions of "UTI," has little significance in identifying individuals who will benefit from treatment. "Urinary symptoms" are similarly uninformative. Neither criterion is well defined. Bacteriuria and symptoms remit and recur spontaneously. Treatment is standard for acute uncomplicated cystitis and common for asymptomatic bacteriuria, but definite benefits are few. Treatment for "UTI" in older adults with delirium and bacteriuria is widespread but no evidence supports the practice, and expert opinion opposes it. Sensitive diagnostic tests now demonstrate that healthy urinary tracts host a ubiquitous, complex microbial community. Recognition of this microbiome, largely undetectable using standard agar-based cultures, offers a new perspective on "UTI." Everyone is bacteriuric. From this perspective, most people who are treated for a "UTI" would probably be better off without treatment. Elderly adults, little studied in this regard, face particular risk. Invasive bacterial diseases such as pyelonephritis and bacteremic bacteriuria are also "UTIs." Mindful decisions about antibiotic use will require a far better understanding of how pathogenicity arises within microbial communities. It is likely that public education and meaningful informed-consent discussions about antibiotic treatment of bacteriuria, emphasizing potential harms and uncertain benefits, would reduce overtreatment. Emphasizing the microbiome's significance and using the term "urinary tract dysbiosis" instead of "UTI" might also help and might encourage mindful study of the relationships among host, aging, microbiome, disease, and antibiotic treatment. © 2017, Copyright the Author Journal compilation © 2017, The American Geriatrics Society.

    The objective of the present paper was to review the use of the dimercaptosuccinic acid (DMSA) scan in urinary tract infection at British Columbia's Children's Hospital to determine the frequency of cortical defects and the association between vesico-ureteric reflux and the presence of cortical defects in children with urinary tract infection. A total of 129 consecutive children with a urinary tract infection referred for a DMSA scan in a 2-year period (January 1992-January 1994) were retrospectively studied. The results were analysed in terms of kidneys, and the incidence of cortical defects was determined. Eighty-eight patients (68%) had a radiographic micturating cysto-urethrogram within 6 months of the DMSA scan, and in this group the relationship of defects with vesico-ureteric reflux was determined. Overall, 81/258 (31%) of kidneys had a cortical defect on a DMSA scan. Of those who had a micturating cysto-urethrogram, 53/176 (30%) kidneys had vesico-ureteric reflux, and of those that had reflux, 21/53 (40%) had a cortical defect on a DMSA scan. In the group of children without reflux, 38/123 (31%) had a cortical defect. Renal cortical scan defects are common findings in paediatric urinary infection, and frequently occur in the absence of vesico-ureteric reflux. These defects represent either established scars or acute pyelonephritis that can proceed to scarring. The micturating cysto-urethro-gram alone is insufficient as a screening modality to identify those kidneys at risk of renal scarring. Copyright (1998) Blackwell Science Pty Ltd

    The association between parents who suffered daytime incontinence as children and children who are incontinence has been reported. However, the association of lower urinary tract (LUT) dysfunction in children and urinary symptoms in mothers has not been studied. To test the hypothesis that the children of mothers with lower urinary tract symptoms (LUTS) are more likely to have urinary symptoms. A cross-sectional multicenter study was conducted in two cities in Brazil. Children/adolescents of 5-17 years of age and their mothers were interviewed. Children with neurological problems, previously detected urinary tract abnormalities or who refused to sign the informed consent or assent form were excluded. The DVSS questionnaire was used to evaluate the presence of LUTS in the children and the ICIQ-OAB questionnaire was used to evaluate their mothers. Constipation in the children was investigated using the ROME III criteria. A total of 827 mother-child pairs were included, with 414 of the children (50.06%) being male. Mean age was 9.1 ± 2.9 years for the children and 35.9 ± 6.5 years for the mothers. Urinary symptoms (occurring at least once or twice a week) were present in 315 children (38.1%), incontinence in 114 (13.8%) and urinary urgency in 141 (17%). Of the mothers, 378 (45.7%) had at least one LUTS, with 103 (12.5%) having incontinence and 153 (18.5%) urgency. According to the DVSS, the overall prevalence of LUT dysfunction was 9.1%. The children's DVSS scores were significantly associated with the mothers' ICIQ-OAB scores (p urinary symptoms were 2.5 times more likely to have a child with LUT dysfunction (95%CI: 1.52-4.17; p incontinence and urinary urgency were also more likely to have incontinence and urgency.

    Lower urinary tract dysfunction-such as urinary incontinence (UI), detrusor overactivity, and benign prostatic hyperplasia-is prevalent in elderly persons. These conditions can interfere with daily life and normal functioning and lead to negative effects on health-related quality of life. UI is one of the most common urologic conditions but is poorly understood elderly persons. The overall prevalence of UI increases with age in both men and women. Elderly persons often neglect UI or dismiss it as part of the normal aging process. However, UI can have significant negative effects on self-esteem and has been associated with increased rates of depression. UI also affects quality of life and activities of daily living. Although UI is more common in elderly than in younger persons, it should not be considered a normal part of aging. UI is abnormal at any age. The goal of this review is to provide an overview of the cause, classification, evaluation, and management of geriatric lower urinary tract dysfunction.

    Full Text Available We aimed to determine the effects of oxidative stress in urinary tract infection (UTI. One hundred sixty-four urine samples obtained from patients with the prediagnosis of acute UTI admitted to the Faculty of Medicine, Kahramanmaras Sutcu Imam University, were included in this study. Urine cultures were performed according to standard techniques. Urinary isolates were identified by using API ID 32E. The catalase and superoxide dismutase activity and the lipid peroxidation levels known as oxidative stress markers were measured in all urine samples. Thirty-six pathogen microorganisms were identified in positive urine cultures. These microorganisms were as follows: 23 (63.8% E coli, 5 (13.8% P mirabilis, 4 (11.1% K pneumoniae, 2 (5.5% Candida spp, 1 (2.7% S saprophyticus, and 1 (2.7% P aeruginosa. It was observed that lipid peroxidation levels were increased while catalase and superoxide dismutase activities were decreased in positive urine cultures, compared to negative cultures. We conclude that urinary tract infection causes oxidative stress, increases lipid peroxidation level, and leads to insufficiency of antioxidant enzymes.

    The function of the lower urinary tract is basically storage of urine in the bladder and the at-will periodic evacuation of the stored urine. Urinary incontinence is one of the most common lower urinary tract disorders in adults, but especially in the elderly female. The urethra, its sphincters, and the pelvic floor are key structures in the achievement of continence, but their basic anatomy is little known and, to some extent, still incompletely understood. Because questions with respect to continence arise from human morbidity, but are often investigated in rodent animal models, we present findings in human and rodent anatomy and histology. Differences between males and females in the role that the pelvic floor plays in the maintenance of continence are described. Furthermore, we briefly describe the embryologic origin of ureters, bladder, and urethra, because the developmental origin of structures such as the vesicoureteral junction, the bladder trigone, and the penile urethra are often invoked to explain (clinical) observations. As the human pelvic floor has acquired features in evolution that are typical for a species with bipedal movement, we also compare the pelvic floor of humans with that of rodents to better understand the rodent (or any other quadruped, for that matter) as an experimental model species. The general conclusion is that the "Bauplan" is well conserved, even though its common features are sometimes difficult to discern.

    Stress urinary incontinence (SUI), the most common type of urinary incontinence (UI), is usually defined as leakage of urine during movement or activity which puts pressure on the bladder, such as coughing, sneezing, running or heavy lifting. It is reported in most countries that 15% to 40% of women struggle with SUI and its severe implications for daily life, including social interactions, sexuality, and psychological wellbeing. The aim of our study was to assess the relationship between urinary tract infection and the severity of stress urinary incontinence (SUI). This research was a cross-sectional study conducted in a public urology clinic in Tehran. The study population was all females with complaints of SUI who visited the clinic during 2014. We compared Valsalva leak point pressure (VLPP) in two groups of patients, with and without history of urinary tract infection (UTI). According to the findings of our study, the mean VLPP was 83.10 cm H2O in the group with UTI history, and 81.29 cm H2O in those without history of UTI. The difference in VLPP between the two groups was not significant (P < 0.05), even after controlling for confounding variables including age, body mass index, history of hysterectomy and number of deliveries. Our study did not confirm a significant relationship between UTI and severity of SUI as measured by VLPP. A decisive opinion would require extensive future studies by prospective methods.

Study objective: to evaluate diagnostic accuracy of deep-stick tests in urinary syndrome verification in pediatric urinary tract infections (UTI. Methods: examination of a urinary sample using standard methods and prompt analysis with urine biochemical composition analyser among 66 children aging from 2 months to 16 years. From this group: 28 children had UTI and 38 other somatic diseases. Results: it has been shown that nitrite test-sticks have low diagnostic sensitivity — 69%, high prognostic value of a positive result (90% and high specificity (94%. Diagnostic sensitivity of leucocytic esterase is 73%, its’ prognostic value of a positive result — 92% and diagnostic specificity — 94%. Erythrocyteuria test had diagnostic sensitivity of 80% and specificity of 95%. Protein test had diagnostic sensitivity of 61% and prognostic value of 64% and 81% specificity. Conclusion: deep-stick test implementation with regard to specifications of this method will allow a more differential approach to it’s use in labs of medicoprophylactic facilities, also reduce the amount of time required for lab urine examinations, as well as to increase reliability of diagnostic information.Key words: children, urinary tract infections, stick-tests, «dry chemistry», diagnostic accuracy, method, urinalysis.

    Full Text Available OBJECTIVE: To prospectively assess the prevalence of vesicourethral dysfunction in children over 3 years old, comparing it with the occurrence rate for other potential factors that cause urinary infection in this age range. MATERIALS AND METHODS: 36 girls and 9 boys were assessed, with mean age of 6.4 years, ranging from 3 to 13.9 years. These children were prospectively assessed regarding the presence of symptoms of lower urinary tract dysfunction. These data were compared with the retrospective assessment of other potential risk factors for urinary infection. Ultrasonography was performed in 28 children and voiding cystourethrogram was performed in 26 patients. RESULTS: Vesicourethral dysfunction was diagnosed in 39 (87% of the 45 children with urinary infection. Among these 39 patients, all had voiding urgency, 30 (77% had urinary incontinence, 12 (31% pollakiuria and 3 (8% presented infrequent voiding. Vaginal discharge was evidenced in 8 (22% girls and phimosis in 2 (22% boys. Obstipation was diagnosed in 10 (22% cases. Significant post-voiding residue was detected in 4 (13% of the 28 cases assessed. Vesicoureteral reflux was evidenced in 5 (19% of the 26 patients who underwent voiding cystourethrogram. In only 2 (4% cases there was not an apparent cause for the infection. CONCLUSION: Vesicourethral dysfunction is a major cause of urinary infection in children with ages above 3 years old. In cases where voiding dysfunction in not present, other predisposing factors must be assessed. However, only 4% of the patients did not present an apparent urologic cause for the infection.

    Full Text Available Although urinary tract infections (UTI represent the most common infection caused by enterococci, some aspects remain to be fully clarified. The aim of this study was to determine the clinical characteristics present in UTI caused by Enterococcus spp. in patients followed up at the Prof. Edgard Santos Teaching Hospital of the Federal University of Bahia. All patients consecutively examined between 1997 and 2005, who received a diagnosis of UTI caused by Enterococcus spp. were included in the study. UTI was defined as the presence of 10(5 colony-forming units per mL of urine. Standard microbiological techniques were used. During the study period, 6.2% of the urine cultures were positive for Enterococcus spp. The mean age of the patients was 48.9 years and 57% were male. At initial evaluation, 13% of the patients had complaints suggestive of UTI. Nineteen patients had a history consistent with obstructive uropathy and 26 with neurogenic bladder. At final evaluation, UTI was the diagnosis in 48 patients. In 36 patients (29%, the primary diagnosis was related to urogenital diseases, consisting of obstructive uropathy in 23 of these cases, while in 32 patients (25.8% primary diagnosis was related to neurologic diseases, frequently neurogenic bladder. UTI caused by Enterococcus spp. is not infrequent, is usually associated with few or no symptoms and occurs in sick patients who have anatomical or functional obstructive uropathy associated or not with urinary tract catheterization or instrumentation. The diagnosis of enterococcal UTI may indicate a urinary tract abnormality yet to be diagnosed.

    In order to clarify the changes of the ureteral function after ureterolithotomy, 131 I-Hippuran renograms were recorded at 3 times before, immediately after (i.e. 1 - 2 days after) and 10 days after the lithotomy in 52 patients. The influences of preoperative hydronephrosis or urinary tract infection upon the postoperative renogram patterns were studied. The following results were obtained. 1. In the renogram findings of the preoperative 52 cases, 28 delayed excretion types, 15 obstructive types and 9 standard types were shown. 2. The postoperative renogram patterns showed a tendency of increased obstruction immediately after the operation (56.9%) irrespective of the location of the calculi in the ureter, and the recovering excretion phases became visible on the 10th postoperative day (51.1%). 3. In the findings on the postoperative renograms, a tendency of increased obstruction was noted in many of the patients of the non-hydronephrotic group than the hydronephrotic group immediately after the operation, but no statistically significant difference was noted. On the 10th postoperative day, slightly more patients of the hydronephrotic group tended to show improvements of obstruction than those of the non-hydronephrotic group, but with no statistically significant difference. 4. In the relationship between the hydronephrosis and urinary tract infection, the infection rate was 26.9% (7 out of 26) in the non-hydronephrotic group and 52.4% (11 out of 21) in the hydronephrotic group. 5. In the findings on the renograms viewed from presence of urinary tract infection, slightly more cases of increased obstruction were found out immediately after the operation in the non-infected group than in the infected group. On the 10th postoperative day, slightly more cases of improvements of obstruction were noted in the infected group than in the non-infected group, but no statistically significant difference was seen between the two groups at either of the two points.

    Unhealthy toileting behaviours exist among women, and lower urinary tract symptoms have a high prevalence and significant effects on quality of life. However, the relationship between toileting behaviours and lower urinary tract symptoms is unclear. This study aimed to investigate the prevalence of lower urinary tract symptoms among female nurses, and the association between toileting behaviours and lower urinary tract symptoms. A cross-sectional stratified cluster sampling study. A total of 636 female clinical nurses from tertiary hospitals in Jinan (the capital city of Shandong Province, China). The Toileting Behaviour-Women's Elimination Behaviours and the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms scales were used to assess the participants' toileting behaviours and lower urinary tract symptoms, respectively. Multiple linear regression analysis was used to evaluate the association between toileting behaviours and lower urinary tract symptoms. Unhealthy toileting behaviours were common among the female nurses, with delayed voiding being the unhealthiest toileting behaviour, which was followed by place and position preference for voiding. Nearly 68% of the female nurses had at least one lower urinary tract symptom, nearly 50% had incontinence symptoms, 40% had filling symptoms, and 18% had voiding symptoms. Unhealthy toileting behaviours (premature voiding, delayed voiding, and straining to void) were positively associated with lower urinary tract symptoms. However, lower urinary tract symptoms were not significantly associated with voiding place or position preference. Among the control variables, being married or having a history of a urinary tract infection was associated with lower urinary tract symptoms. Having a higher income and regular menstrual period were negatively associated with lower urinary tract symptoms. Compared with vaginal delivery, caesarean delivery had a protective association with lower

    The Pediatric Lower Urinary Tract Scoring System (PLUTSS) is a standardized questionnaire used for screening and evaluation of the response of children with lower urinary tract symptoms (LUTS) to therapy. We presumed that adding the Child Behavior Check List (CBCL) and bladder volume wall index (BVWI) to the PLUTSS would increase its validity in the detection of children with LUTS. One hundred twenty-two children aged 5 to 15 years with LUTS were enrolled in the study. Seventy-two healthy, age-matched children without urinary complaints were considered as controls. The PLUTSS and CBCL were filled out for all children. Sonography was performed to measure BVWI. Chi-square test and likelihood ratio were used to compare frequencies, receiver operating curve (ROC) analysis was used to evaluate the correlation, and Cohen's kappa was used to measure the agreement between variables. p-values 0.05). ROC analysis showed that there was no correlation between PLUTSS, CBCL, and BVWI in either the LUTS subgroup or in the controls (p>0.05). The PLUTSS had the highest sensitivity and specificity, and adding the two other tests decreased its validity for the diagnosis of children with LUTS. The PLUTSS by itself was the best predictor of LUTS. The CBCL and BVWI were not helpful in making a diagnosis; however, the CBCL was useful in the detection of behavior problems in children with non-monosymptomatic enuresis.

    Full Text Available Recurrent urinary tract infections are a serious clinical problem both in adults and children. Febrile episodes of recurrent urinary tract infections may lead to the formation of renal scars and development of chronic kidney disease. Traditionally, management involved antibiotic prophylaxis introduced after a first febrile episode. Recently, however, the indications for antibiotic therapy have been narrowed down to treat cases of recurrent urinary tract infections and disorders which pose a significant risk for their development. In the current era of the ubiquitous use of antibiotics, bacterial resistance is an increasingly alarming problem, hence the recent search for alternative methods of prophylactic treatment. For many reasons, probiotics appear to be an excellent alternative. The microbiome of the human gastrointestinal tract and urogenital tract consists of a multitude of helpful probiotic bacteria, including the especially beneficial Lactobacillus strain. A significant relationship has been confirmed to exist between infections of the urinary tract and a decreased number of lactobacilli. Their antibacterial properties include their ability to  secrete numerous substances inhibiting the growth of  pathogenic microorganisms and to form a biofilm preventing the adhesion of uropathogens to the epithelium of the urinary tract as well as, indirectly, their immunomodulatory potential. This study is aimed at discussing the existing evidence supporting the effectiveness of probiotics in the prophylaxis of recurrent urinary tract infections, with special emphasis on the paediatric population. Probiotics make an excellent and safe alternative for the traditional prophylactic antibiotic therapy.

    The experiments performed in this PhD thesis were conducted at the Institute of Experimental Surgery, Skejby Hospital, Aarhus, Denmark and at the Laboratory of Animal Science, Odense University Hospital, Denmark. The thesis is based on 3 peer review articles published in international journals and a review. Diagnostic or therapeutic endoscopic upper urinary tract procedures are usually characterised as minimal invasive procedures and associated with a low complication rate. Most often fever or pain are seen and sometimes septicaemia. However, mucosa lesion or even ureteric ruptures are known complications. Research has suggested that high renal pelvic pressures generated during these procedures, might contribute to per-/postoperative complications seen, and even possible renal parenchymal damage. Nevertheless, local administration (endoluminal) of a relaxant drug has not previously been tried in order to lower renal pelvic pressure. The purposes of this thesis were to examine the effect of local administration (endoluminal) of the nonspecific β-adrenergic agonist ISOproterenol (ISO) on: 1) The normal pressure flow relation in porcine ureter, 2) The effect of endoluminal ISO perfusion during flexible ureterorenoscopy, 3) The pressure flow relation during semirigid ureterorenoscopy and 4) The cardiovascular system. Among other receptor-types β-adrenergic receptor are located in the upper urinary tract and the activation thereof mediates smooth muscle relaxation. We have shown - in an animal experimental model - that ISO added to the irrigation fluid had significant impact on the renal pelvic pressures generated during upper urinary tract endoscopy. ISO significantly and dose dependently reduced the normal pressure flow relations by approximately 80% without concomitant cardiovascular side effects or measurable plasma levels of ISO. During flexible ureterorenoscopy 0.1 µg/ml ISO added to the irrigation fluid significantly reduced renal pelvic pressure during

    Synopsis Urinary tract infections (UTIs) are a significant cause of morbidity among older adults; however, antibiotic prescriptions for clinically suspected UTIs are often inappropriate. Healthcare providers frequently struggle to differentiate UTI from asymptomatic bacteriuria, particularly in patients presenting with nonspecific symptoms. Patients with baseline cognitive impairments that limit history-taking can be particularly challenging. Here, we review the epidemiology and pathogenesis of UTI in older adults. We also discuss an approach to the diagnosis and treatment of UTIs, focusing on recognizing patients who would likely benefit from antibiotic treatment and on identifying patients for whom empiric antibiotic therapy should not be given.

    Full text: The macroscopic haematuria is one of the most common reasons for visit in emergency urology clinic. Urology massive hematuria may be caused by inflammation, gallstones, trauma, benign and malignant tumors. The issue of 'Essential' haematuria, typically of the upper urinary tract - one where it is not established cause, stands for decades. With the introduction of new diagnostic technologies - imaging and instrumentation, the share of 'Essential' haematuria, decreased. The aim of the study was to investigate and establish the diagnostic value of venous and CT urography, MRI and ureterorenoscopy in case of chronic 'essential' haematuria from the upper urinary tract by comparing their specificity and sensitivity. For a period of three years 214 patients were prospectively followed and hospitalized with macroscopic haematuria. All were examined with ultrasonography, radiography of the kidneys, ureters and bladder, cystoscopy. In 20 of the patients was excluded pathology of lower urinary tract as a cystoscope establish bleeding ureteral ostium / ostium, but diagnosis or direction of such a listed methods could not be found. Patients were subjected to IVP, then CT urography or MRI (in patients with elevated serum creatinine) and rigid ureterorenoscopy in this sequence and the results were analyzed. Of these 20 patients, 9 were diagnosed with malignancy, 4 - X-ray-negative lithiasis, eroded court, 4 - hemangioma changes or bleeding benign mucosa, 1 arterio-venous fistula, 2 were not finally diagnosed . 10 patients were diagnosed by IVP, which was confirmed by other methods (sensitivity 56.2%, specificity 75.7%). Both indicators were more robustly to cases of urothelial carcinoma pielon or ureter (respectively 66.9% and 84.4%). For CT urography and MRI the total sensitivity for detection of pathology was 85.8%, specificity 94.5%. In our series has revealed no statistically significant difference between the possibility of diagnosis

    Urinary tract infections (UTIs) are a severe public health problem and are caused by a range of pathogens, but most commonly by Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Enterococcus faecalis and Staphylococcus saprophyticus. High recurrence rates and increasing antimicrobial resistance among uropathogens threaten to greatly increase the economic burden of these infections. In this Review, we discuss how basic science studies are elucidating the molecular details of the crosstalk that occurs at the host–pathogen interface, as well as the consequences of these interactions for the pathophysiology of UTIs. We also describe current efforts to translate this knowledge into new clinical treatments for UTIs. PMID:25853778

    Full Text Available Abstract Enterobius vermicularis is an intestinal nematode of humans. Adults usually have low worm burdens and are asymptomatic. Ectopic infections in the pelvic area or urinary tract rarely occur in women. We report a case of the patient with mild voiding difficulties such as urgency, frequency, nocturia, dysuria, mild low back pain or perineal discomfort. The patient's prostatic secretions showed a large number of inflammatory cells and several eggs. The size and the shape of the eggs identified them as a group of E. vermicularis. On examination we found a soft palpable material which was 5 mm diameter in size and spherical shape. Palpation gave the impression of a tissue than a stone. An incision was performed and a 4 mm long living worm was found. The microscopic examination identified the worm as E- vermicularis. It is an extremely rare manifestation of enterobius vermicularis infection since an intestinal-breeding worm is rarely found in the male genital tract.

    Given that YKL-40 is a known marker of inflammation, we sought to determine its association with urinary tract infection (UTI) in febrile children. In total, 44 children aged 0 to 24 months with febrile UTI and 35 age- and sex-matched controls with fever from other causes were enrolled in the study. ELISA was performed to determine the level of YKL-40 in urine collected from each child. The ratio of urinary YKL-40 to creatinine (Cr) was higher in the children with a UTI than in the controls (P40/Cr ratio, 0.86 for pyuria, and 0.71 for positive nitrite on urinalysis. We applied a cut-off value of 125.23 pg/mg to urinary YKL-40/Cr for detecting UTI. Eight of nine children in the control group with pyuria had urinary YKL-40/Cr levels lower than 125.23 pg/mg, and the one child in the UTI group without pyuria or positive nitrite had a urinary YKL-40/Cr level greater than 125.23 pg/mg. Determining the levels of urinary YKL-40/Cr may help identify true cases of UTI in febrile young children, especially when they have pyuria but not nitrite, or have neither pyuria nor nitrite in the urine. © The Korean Society for Laboratory Medicine

    The microbiome is the term used for the symbiotic microbial colonisation of healthy organs. Studies have found bacterial identifiers within voided urine which is apparently sterile on conventional laboratory culture, and accordingly there may be health and disease implications. The International Consultation on Incontinence Research Society (ICI-RS) established a literature review and expert consensus discussion focussed on the increasing awareness of the urinary microbiome, and potential research priorities. The consensus considered the discrepancy between findings of conventional clinical microbiology methods, which generally rely on culture parameters predisposed towards certain "expected" organisms. Discrepancy between selective culture and RNA sequencing to study species-specific 16S ribosomal RNA is increasingly clear, and highlights the possibility that protective or harmful bacteria may be overlooked where microbiological methods are selective. There are now strong signals of the existence of a "core" urinary microbiome for the human urinary tract, particularly emerging with ageing. The consensus reviewed the potential relationship between a patient's microbiome and lower urinary tract dysfunction, whether low-count bacteriuria may be clinically significant and mechanisms which could associate micro-organisms with lower urinary tract symptoms. Key research priorities identified include the need to establish the scope of microbiome across the range of normality and clinical presentations, and gain consensus on testing protocols. Proteomics to study enzymatic and other functions may be necessary, since different bacteria may have overlapping phenotype. Longitudinal studies into risk factors for exposure, cumulative risk, and emergence of disease need to undertaken. Neurourol.

    Carcinoma in situ of the urinary tract is a high grade form of nonmuscle invasive urothelial cancer. Our understanding of this entity in the upper tract is poor, and case management remains challenging due to knowledge gaps regarding the definition, diagnosis, treatment options and followup of the disease. We reviewed the available literature for similarities and differences between bladder and upper tract carcinoma in situ, and herein summarize the best available data. We reviewed PubMed® and MEDLINE™ databases from January 1976 through September 2014. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement was used to screen publications. All authors participated in the development of a consensus definition of disease. A total of 61 publications were found suitable for this review. All studies were retrospective. Compared to bladder carcinoma in situ, upper tract carcinoma in situ appears to have lower progression rates and improved survival. All available studies demonstrate topical therapy to be effective in treating upper tract carcinoma in situ, with decreased recurrence rates compared to bladder carcinoma in situ. Highlighted areas of current knowledge gaps include variable definitions of disease, methods of drug delivery and ideal treatment course. Improving methods for detection may allow easier diagnosis and more effective treatment. Based on the available data, organ preserving therapy with topical agents is an alternative to radical surgery in select patients with upper tract carcinoma in situ, although this method has not been evaluated in prospective trials. A paradigm shift regarding detection and treatment is needed to improve care and allow better renal preservation. A consensus definition of the disease is offered, and several areas of major knowledge gaps and opportunities for future research are identified.

    Symptomatic urinary tract infection is a complication of office based cystourethroscopy. Studies are mixed regarding the efficacy of antibiotic prophylaxis to prevent urinary tract infections. Our aim was to develop and evaluate an evidence-based protocol that reduces unnecessary antibiotic use while avoiding an increase in urinary tract infections. We created a clinic antibiogram based on all urology office visits performed during a 2-year period. Bacterial resistance rates, institutional risk related data and clinical guidelines were applied to create a protocol for antibiotic administration before cystourethroscopy. We then analyzed 1,245 consecutive patients without a renal transplant who underwent outpatient cystourethroscopy, including 610 after protocol initiation. Urinary tract infection rates and antibiotic use were analyzed for an association with the protocol change using the Fisher exact test. Cultures had an overall 20% rate of resistance to fluoroquinolones, representing 40% of the cultures that grew Escherichia coli. Before the protocol change 602 of 635 patients (94.8%) received a preprocedural antibiotic compared to 426 of 610 (69.9%) after protocol initiation (p urinary tract infection prior to the protocol change while 16 (2.6%) had a urinary tract infection after the change (p = 0.69). Regarding resistance, fluoroquinolone resistant organisms grew in the cultures of 12 of 19 patients (63.2%) with a urinary tract infection before the protocol change compared to 5 of 16 (31.3%) with a urinary tract infection after the change. Recent antibiotic administration, hospitalization and chronic catheterization were associated with urinary tract infection in the entire cohort (all p ≤0.01). A local antibiogram with infection related risk data effectively risk stratifies patients before cystourethroscopy, decreasing the use of antibiotics without increasing the rate of symptomatic urinary tract infection.

    To identify which independent variable would be strong predictor of febrile urinary tract infection (UTI) in children and adolescents with overactive bladder. A search was made of the institute's database for all patients diagnosed with overactive bladder over the preceding four years. Children and adolescents under 18 years of age with overactive bladder and no neurological or anatomical alterations of the lower urinary tract were included in the study. The independent variables were: sex, age, ethnicity (Brazilians of African descendence/others), the presence of urinary urgency, daytime incontinence, enuresis, frequent urination, infrequent voiding (≤3 voids/day), nocturia, holding maneuvers, straining to void, intermittent urinary flow, constipation and encopresis. An analysis was conducted to identify patients with febrile UTI and subsequently determine predictors of this condition. Univariate and multivariate analyses were performed. Overall, 326 patients (214 girls/112 boys) were evaluated. The mean age of the patients was 7.7±3.19 years (± standard deviation). The incidence of febrile UTI was 39.2%. Being female and infrequent voiding were factors significantly associated with febrile UTI, both in the univariate and multivariate analyses. These results show that being female and infrequent voiding constituted significant risk factors for a diagnosis of febrile UTI in these children.

    Neuromodulation therapy incorporates electrical stimulation to target specific nerves that control lower urinary tract symptoms (LUTS). The objectives of this article are to review the mechanism of action, the type of neuromodulation, and the efficacy of neuromodulation mainly according to the results of randomized controlled trials. Neuromodulation includes pelvic floor electrical stimulation (ES) using vaginal, anal and surface electrodes, interferential therapy (IF), magnetic stimulation (MS), percutaneous tibial nerve stimulation, and sacral nerve stimulation (SNS). The former four stimulations are used for external periodic (short-term) stimulation, and SNS are used for internal, chronic (long-term) stimulation. All of these therapies have been reported to be effective for overactive bladder or urgency urinary incontinence. Pelvic floor ES, IF, and MS have also been reported to be effective for stress urinary incontinence. The mechanism of neuromodulation for overactive bladder has been reported to be the reflex inhibition of detrusor contraction by the activation of afferent fibers by three actions, i.e., the activation of hypogastric nerve, the direct inhibition of the pelvic nerve within the sacral cord and the supraspinal inhibition of the detrusor reflex. The mechanism of neuromodulation for stress incontinence is contraction of the pelvic floor muscles through an effect on the muscle fibers as well as through the stimulation of pudendal nerves. Overall, cure and improvement rates of these therapies for urinary incontinence are 30-50, and 60-90% respectively. MS has been considered to be a technique for stimulating nervous system noninvasively. SNS is indicated for patients with refractory overactive bladder and urinary retention. © 2015 Wiley Publishing Asia Pty Ltd.

    Accurate and early diagnosis and appropriate treatment of patient with urinary tract infection (UTI) are essential for the prevention or restriction of permanent damage to the kidneys in children. The aim of this study was to compare renal ultrasonography (US) and dimercaptosuccinic acid (DMSA) renal scan in the diagnosis of patients with febrile urinary tract infection. This study involved the medical records of children with febrile urinary tract infection who were admitted to the children's hospital in Qazvin, Iran. Pyelonephritis was diagnosed on the basis of clinical symptoms, laboratory tests and abnormal DMSA renal scans. The criteria for abnormality of renal US were an increase or a decrease in diffuse or focal parenchymal echogenicity, loss of corticomedullary differentiation, kidney position irregularities, parenchymal reduction and increased kidney size. Of the 100 study patients, 23% had an abnormal US and 46% had an abnormal DMSA renal scan. Of the latter patients, 15 had concurrent abnormal US (P value ≤ 0.03, concordance rate: 18%). Renal US had a sensitivity of 32%, specificity of 85%, positive predictive value of 65% and negative predictive value of 60%. Of the 77 patients with normal US, 31 (40.2%) had an abnormal DMSA renal scan. Despite the benefits and accessibility of renal US, its value in the diagnosis of pyelonephritis is limited.

  14. Recurrent urinary tract infections in women: How promising is the use of probiotics?

    Full Text Available Urinary tract infections (UTIs currently rank amongst the most prevalent bacterial infections, representing a major health hazard. UTIs in females usually start as vaginal infections and ascend to the urethra and bladder. Recurrent UTIs (rUTIs can be defined as at least three episodes of UTI in 1 year or two episodes in 6 months. Various antibiotics have been the mainstay of therapy in ameliorating the incidence of UTIs, but recurrent infections continue to afflict many women. It necessitates the exploitation of alternative antimicrobial therapy. Probiotics have been shown to be effective in varied clinical trials for long-term preventions of rUTI. Because Escherichia coli is the primary pathogen involved in UTIs which spreads from the rectum to vagina and then ascends up the sterile urinary tract, improving the gut or vaginal flora will thus impact the urinary tract. Since a healthy vaginal microbiota is mainly dominated by Lactobacillus species, in this context, exogenously administered probiotics containing Lactobacilli play a pivotal role in reducing the risk of rUTI. The concept of artificially boosting the Lactobacilli numbers through probiotic administration has long been conceived but has been recently shown to be possible. Lactobacilli may especially be useful for women with a history of recurrent, complicated UTIs or on prolonged antibiotic use. Probiotics do not cause antibiotic resistance and may offer other health benefits due to vaginal re-colonisation with Lactobacilli. However, more comprehensive research is still needed, to recommend for probiotics as an alternative to antibiotics.

    Background Ultrasonographic (US) screening of the urinary tract (UT) in infants was used to determine if there is a connection between the frequency of pyelocaliceal dilation (PCD) in asymptomatic infants with normal antenatal US screening and occurrence of congenital anomalies of kidney and urinary tract (CAKUT) and urinary tract infections (UTI). Material/Methods US screening of the UT was performed on 1000 healthy infants, 7 days to 6 months old. Two subgroups of kidneys were described: subgroup 1 contained kidneys with anterior posterior pelvic diameter (APPD) of 5–9.9 mm, and subgroup 2 with APPD over 10 mm. US examinations and methods for detection of UTI and CAKUT were used. Results PCD was found in 74 infants (7.4%): 1.9% of infants had CAKUT, and 8.4% had UTI. In subgroup 1, CAKUT was found in 4 (6.3%) and UTI in 9 (14.3%) infants. In subgroup 2, CAKUT was found in 6 (54.5%), and UTI in 4 (36.4%) infants. Conclusions Mild PCD significantly increases the risk for CAKUT but not for UTI. Moderate to severe PCD significantly increases risk for both CAKUT and UTI. The postnatal US screening of UT is recommended for improved detection of PCD and associated CAKUT. Indirectly, postnatal US screening of UT can help in detecting people at risk for UTI in the first year of life, and therefore help prevent possible kidney damage. PMID:23419315

    At present, various diagnostic and therapeutic approaches are available for urinary tract infections. But, still the quest for development of more rapid, accurate and reliable approach is an unending process. The pathogens, especially uropathogens are adapting to new environments and antibiotics day by day rapidly. Therefore, urinary tract infections are evolving as hectic and difficult to eradicate, increasing the economic burden to the society. The technological advances should be able to compete the adaptability characteristics of microorganisms to combat their growth in new environments and thereby preventing their infections. Nanotechnology is at present an extensively developing area of immense scientific interest since it has diverse potential applications in biomedical field. Nanotechnology may be combined with cellular therapy approaches to overcome the limitations caused by conventional therapeutics. Nanoantibiotics and drug delivery using nanotechnology are currently growing areas of research in biomedical field. Recently, various categories of antibacterial nanoparticles and nanocarriers for drug delivery have shown their potential in the treatment of infectious diseases. Nanoparticles, compared to conventional antibiotics, are more beneficial in terms of decreasing toxicity, prevailing over resistance and lessening costs. Nanoparticles present long term therapeutic effects since they are retained in body for relatively longer periods. This review focuses on recent advances in the field of nanotechnology, principally emphasizing diagnostics and therapeutics of urinary tract infections. Copyright © 2017 Elsevier B.V.

    Diagnosing urinary infection in patients with chronic lower urinary tract symptoms without dysuria is a critical step. In this study we scrutinize the sensitivity and specificity of dipstick urinalysis and microscopic pyuria (10 or more white blood cells per microl) to identify infection in such patients. This was a prospective, blinded, observational cohort study of urological outpatients with painless lower urinary tract symptoms. Midstream and catheter urine samples were analyzed. A total of 508 midstream urine samples were used to compare leukocyte esterase, nitrite dipstick and urine microscopy with cultures seeking 10(5) cfu/ml. Similarly 470 catheter urine samples were used to compare the same surrogates with 10(5) cfu/ml and with an enhanced culture method seeking 10(2) cfu/ml. A comparison of leukocyte esterase against microscopic pyuria was made using the 508 midstream and 470 catheter specimens of urine. Midstream urine specimens were provided by 42 normal volunteers for comparison. For a midstream urine culture at 10(5) cfu/ml leukocyte esterase was 56% sensitive, nitrite was 10% sensitive and microscopic pyuria was 56% sensitive. Specificities were 66%, 99% and 72%, respectively. For a catheter specimen of urine culture at 10(5) cfu/ml leukocyte esterase was 59% sensitive, nitrite was 20% sensitive and microscopic pyuria was 66% sensitive. Specificities were 84%, 97% and 73%, respectively. The enhanced culture of catheter specimen of urine at 10(2) cfu/ml was positive in 29% of patients vs 15% at 10(5) cfu/ml. Despite official guidelines and widespread use these tests cannot be considered appropriate for diagnosing urinary tract infection in patients with lower urinary tract symptoms, and should be abandoned in this context.

    During the period of 4 years from July, 1976 to June 1980 the radiological and clinical evaluation had been made on 102 patients suffered from lower urinary tract injuries which were confirmed by the radiological examination and operation. The results were as follows: 1. Age distribution of the total 102 patients (87 males and 15 females) was broad from 4 to 72 years. And most of the patient were in the age group of 20 to 49 years. 2. The most common cause of injury was traffic accident (67.6%), next blunt trauma, saddle injury, fall down respectively. 3. 46 patients of bladder injury were as follows: intraperitoneal rupture in 17, extraperitoneal rupture in 12, and contusion in 14. 4. 74 patients of urethral injury were as follows: membranous portion in 37, bulbous portion in 31, prostatic portion in 3, and penile portion in 2. Most of the cases showed extravasation of contrast media. 12 cases showed extravasation with venous intravasation. 5. Contusion or extraperitoneal rupture of the bladder, membranous urethral injury, and concommitent bladder and urethral ruptures were frequently associated with pelvic bone fracture. Intraperitoneal ruptures of the bladder and solitary ruptures of the bulbous urethra were infrequently associated with pelvic bone fracture. 6. Late sequelae of the lower urinary tract injury were stricture, fistula and stone formation

    Full Text Available Kawasaki disease (KD is a systemic vasculitis and can develop multiple organ injuries including kidney and urinary tract involvement. These disorders include pyuria, prerenal acute kidney injury (AKI, renal AKI caused by tubulointerstitial nephritis (TIN, hemolytic uremic syndrome (HUS, and immune-complex mediated nephropathy, renal AKI associated with either Kawasaki disease shock syndrome or unknown causes, acute nephritic syndrome (ANS, nephrotic syndrome (NS, renal tubular abnormalities, renal abnormalities in imaging studies, and renal artery lesions (aneurysms and stenosis. Pyuria is common in KD and originates from the urethra and/or the kidney. TIN with AKI and renal tubular abnormalities probably result from renal parenchymal inflammation caused by T-cell activation. HUS and renal artery lesions are caused by vascular endothelial injuries resulting from vasculitis. Some patients with ANS have immunological abnormalities associated with immune-complex formation. Nephromegaly and renal parenchymal inflammatory foci are detected frequently in patients with KD by renal ultrasonography and renal scintigraphy, respectively. Although the precise pathogenesis of KD is not completely understood, renal vasculitis, immune-complex mediated kidney injuries, or T-cell immune-regulatory abnormalities have been proposed as possible mechanisms for the development of kidney and urinary tract injuries.

    Objective was to determine the resistance of antibiotics for complicated urinary tract infection (UTI), including urinary tract anomaly (UTA), for empirical antibiotic therapy of complicated UTI. Four hundred and twenty two urine isolates were obtained from 113 patients with recurrent UTI, who used prophylactic antibiotics between February 1999 and November 2004 in the Eskisehir Osmangazi University, Eskisehir, Turkey. Reflux was found to be most important predisposing factor for recurrent UTI (31.9%). Renal scar was detected more in patients with UTA than without UTA (59.2% versus 12.4%, p<0.05). Gram-negative organisms were dominant in patients with and without UTA (91.5% and 79.2%). Enterococci and Candida spp. were more prevalent in children with UTA than without UTA (p<0.001). Isolates were significantly more resistant to ampicillin, trimethoprim-sulfamethoxazole, amikacin, co-amoxiclav, ticarcillin-clvalanate and piperacillin-tazobactam in patients with UTA than without UTA. We found low resistance to ciprofloxacin and nitrofurantoin in UTI with and without UTA. Enterococci spp. was highly resistance to ampicillin and amikacin in patients with UTA. Aztreonam, meropenem and ciprofloxacin seemed to be the best choice for treatment of UTI with UTA due to Escherichia coli and Klebsiella spp. Nitrofurantoin and nalidixic acid may be first choice antibiotics for prophylaxis in UTI with and without UTA. The UTI with UTA caused by Enterococci spp. might not benefit from a combination of amikacin and ampicillin, it could be treated with glycopeptides. (author)

    Full Text Available Daniele Minardi, Gianluca d'Anzeo, Daniele Cantoro, Alessandro Conti, Giovanni MuzzonigroDepartment of Clinical and Specialist Sciences, Urology, Polytechnic University of the Marche Medical School and United Hospitals, Ancona, ItalyAbstract: Urinary tract infections (UTI are common among the female population. It has been calculated that about one-third of adult women have experienced an episode of symptomatic cystitis at least once. It is also common for these episodes to recur. If predisposing factors are not identified and removed, UTI can lead to more serious consequences, in particular kidney damage and renal failure. The aim of this review was to analyze the factors more commonly correlated with UTI in women, and to see what possible solutions are currently used in general practice and specialized areas, as well as those still under investigation. A good understanding of the possible pathogenic factors contributing to the development of UTI and its recurrence will help the general practitioner to interview the patient, search for causes that would otherwise remain undiscovered, and to identify the correct therapeutic strategy.Keywords: urinary tract infection, women, etiology, diagnosis, treatment

    Urinary tract infection(UTI) is one of the major bacterial disease of children that causes morbidity and inconvenience to many patients were related to recurrent vesicoureteral reflux. Radiological examinations of the 72 patients of urinary tract infection(UTI) who were visited to Seoul Paik Hospital from Jan 1st 1986 to Jul 30th 1989, were analysed in this study. US was used as an initial study in all patients who showed acute stage of UTI and followed by IVP, VCUG, 99m Tc-DMSA scan for veslcoureteral reflex or renal scarring. If US showed obstructing lesion, no further study was performed. The resulted were as follows: 1. US is valuable as a screening procedure during the first UTI in congenital abnormalities and in particular obstructive lesions that require surgery. 2. A normal US in a child older than 5 or 6 years is meaningful as an investigation in the group of the first documented UTI uncomplicated. 3. Vesicoureteral reflex, a major factor leading to parenchymal damage in young children can not be detected reliably by US. If the US is suggestive of vesicoureteral reflex, this should be confirmed by VCUG and 99m Tc-DMSA scan for renal scarring. If the US is normal or equivocal in recurrent infection and unexplained persistent clinical findings, this should be followed by VCUG and 9 9mTc-DMSA scan

    Full Text Available PURPOSE: Urinary tract infection is the most common nosocomially acquired infection. It is important to know the etiology and antibiotic susceptibility infectious agents to guide the initial empirical treatment. OBJECTIVE: To determine the prevalence of bacterial strains and their antibiotic susceptibility in nosocomially acquired urinary tract infection in a university hospital between January and June 2003. METHODS: We analyzed the data of 188 patients with positive urine culture (= 10(5 colony-forming units/mL following a period of 48 hours after admission. RESULTS: Half of patients were male. Mean age was 50.26 ± 22.7 (SD, range 3 months to 88 years. Gram-negative bacteria were the agent in approximately 80% of cases. The most common pathogens were E. coli (26%, Klebsiella sp. (15%, P. aeruginosa (15% and Enterococcus sp. (11%. The overall bacteria susceptibility showed that the pathogens were more sensible to imipenem (83%, second or third generation cephalosporin and aminoglycosides; and were highly resistant to ampicillin (27% and cefalothin (30%. It is important to note the low susceptibility to ciprofloxacin (42% and norfloxacin (43%. CONCLUSION: This study suggests that if one can not wait the results of urine culture, the best choices to begin empiric treatment are imipenem, second or third generation cephalosporin and aminoglycosides. Cefalothin and ampicillin are quite ineffective to treat these infections.

    To address to a better understanding of whether increased water consumption is associated with beneficial effects of urinary tract infections prophylaxis and treatment, and if so, the mechanism involved in this process. Models of the catheterized bladder were infected with Escherichia coli. Artificial urine was supplied at various flow rates and various concentrations to separately assess the "flushing effect" and "dilution effect" of increased water consumption on catheter blockage time, encrustation formation, and bacterial growth. There were no statistical significances regarding catheter blockage time (P = 0.92), encrustation formation, and bacterial growth among bladder models supplied with various flow rates. When the flow rate was set as 1 ml/min, however, there showed significant decrease trend of the time to blockage (P = 0.0005), encrustation formation, and bacterial growth as the concentration of the artificial urine increased except the twofold-concentration urine group. Increased water consumption is associated with beneficial effects of urinary tract infection prophylaxis and treatment, and dilution effect of bacteria nutrition in the urine is at least partly involved in this process if not all, rather than the "flushing effect". Considering the flaws and the in vitro design of the current study, however, an in vivo study is warranted.

    Uncomplicated bacterial urinary tract infections (UTIs) occur commonly in dogs. Persistent or recurrent infections are reported less frequently. They typically occur in dogs with an underlying disease and are sometimes asymptomatic, especially in dogs with predisposing chronic disease. Escherichia coli is the organism most frequently cultured in both simple and complicated UTIs. Organisms such as Enterococcus spp. and Pseudomonas spp. are less common in uncomplicated UTI, but become increasingly prominent in dogs with recurrent UTI. The ability of bacteria to acquire resistance to antimicrobials and/or to evade host immune defence mechanisms is vital for persistence in the urinary tract. Antimicrobial therapy limitations and bacterial strains with such abilities require novel control strategies. Sharing of resistant bacteria between humans and dogs has been recently documented and is of particular concern for E. coli O25b:H4-ST131 strains that are both virulent and multi-drug resistant. The epidemiology of complicated UTIs, pathogenic traits of uropathogens and new therapeutic concepts are outlined in this review. Copyright © 2011. Published by Elsevier Ltd.

    Kidney and bladder stones (urinary tract stones) and osteoporosis are prevalent, serious conditions for postmenopausal women. Men with kidney stones are at increased risk of osteoporosis; however, the relationship of urinary tract stones to osteoporosis in postmenopausal women has not been established. The purpose of this study was to determine whether urinary tract stones are an independent risk factor for changes in bone mineral density (BMD) and incident fractures in women in the Women's Health Initiative (WHI). Data were obtained from 150,689 women in the Observational Study and Clinical Trials of the WHI with information on urinary tract stones status: 9856 of these women reported urinary tract stones at baseline and/or incident urinary tract stones during follow-up. Cox regression models were used to determine the association of urinary tract stones with incident fractures and linear mixed models were used to investigate the relationship of urinary tract stones with changes in BMD that occurred during WHI. Follow-up was over an average of 8 years. Models were adjusted for demographic and clinical factors, medication use, and dietary histories. In unadjusted models there was a significant association of urinary tract stones with incident total fractures (HR 1.10; 95% CI, 1.04 to 1.17). However, in covariate adjusted analyses, urinary tract stones were not significantly related to changes in BMD at any skeletal site or to incident fractures. In conclusion, urinary tract stones in postmenopausal women are not an independent risk factor for osteoporosis. © 2015 American Society for Bone and Mineral Research.

    There is emerging awareness of comorbid psychosocial characteristics in children with lower urinary tract dysfunction. To explore the prevalence of these comorbidities and their relationship to lower urinary tract symptoms, we examined the psychosocial comorbidities and body mass index of children with lower urinary tract dysfunction. We prospectively collected data on all new patients 6 to 17 years old with nonneurogenic lower urinary tract dysfunction who presented to a single nurse practitioner in 2011. Parents completed a 21-question lower urinary tract symptom score based on a validated questionnaire and a psychosocial questionnaire that screened for stressful life events and psychological diagnoses. We examined the correlation of body mass index percentile and psychosocial comorbidities with lower urinary tract symptom score. Of the 358 patients 28.5% were obese, 31.8% had a recent life stressor and 22.9% had a comorbid psychiatric disorder. Younger age correlated with a higher lower urinary tract symptom score (r = -0.34, p urinary tract symptom score than children without comorbidities. Underweight and obese children had a significantly higher lower urinary tract symptom score than healthy weight and overweight children (p = 0.009). Almost a third of the patients in our study were obese. More than 40% of the children had a psychiatric disorder and/or recent life stressor. Younger age, an underweight or obese body mass index and a recent stressful life event or psychiatric disorder correlated with a higher lower urinary tract symptom score. This study supports previous recommendations to screen for psychosocial comorbidities and obesity during the evaluation of pediatric lower urinary tract dysfunction.

    Urination disorders start to appear in an age-dependent fashion, which contribute to the degradation of quality of life (QOL) in erderly persons. This study focused on elucidating changes of the lower urinary tract symptoms (LUTS) and changing of voiding condition with aging in the subjects, who offered the health checks. We evaluated urinary function in 225 Japanese males (age 20-79), estimated International prostate symptom score (IPSS), QOL score, uroflowmetry, prostate volume and residual urine (estimated from transabdominal ultrasonography). In addition, 539 females (age 20-89) were assigned IPSS and QOL scores. The distribution of severity of symptoms significantly changed with age in both sexes. QOL scores tended to increase in males, IPSS, prostate volume and residual urine were significantly increasing related to age, and advanced age was associated with a decline of voiding volume and Qmax. Comparison of QOL scores and IPSS criteria demonstrated a significantly positive correlation with incomplete emptying and a weak stream. A significant negative correlation was found between the QOL score and Qmax. The distribution of middle level of symptom, divided by clinical guideline for benign prostatic hyperplasia, significantly increased with age. On the other hand, in females, the QOL score seemed to be stable whilst there was a slight increase of IPSS. In contrast, frequency and incomplete emptying were significantly related to QOL scores. These investigations supported changing of lower urinary tract disorder with aging in both sexes. Since the approximate 50% of sixth and seventh decade males, classified to the middle level of symtom, which need treatment, the high incident of degradation of the LUTS with age, should predict for the future.

    This study aimed to investigate associations between primary urinary incontinence and development of upper urinary tract stones in a nationwide population in Taiwan. Data of 1,777 adults with primary urinary incontinence and 26,655 controls (groups A, B, and C) without urinary incontinence at study inception were retrieved from the National Health Insurance System database in Taiwan and were analyzed retrospectively. No enrolled subjects had previous diagnosis of upper urinary tract stones or spinal cord injury. All subjects were followed through end of 2009, with a minimum follow-up of 8 years. A greater percentage of study subjects (334/1777, 18.8%) developed upper urinary tract stones than that of control groups A (865/8885, 9.7%) and B (888/8885, 10%), and C (930/8885, 10.5%) (all p-values Urinary incontinence was associated with significantly increased risk of developing urinary tract stones (HR 1.99, 95% CI, 1.70-2.34, p urinary tract stones (both p-values urinary incontinence was still associated with a significantly increased risk of developing upper urinary tract stones (HR 1.99, 95% CI = 1.76-2.26, p urinary incontinence suggests that urinary incontinence is associated with a significantly increased risk of developing upper urinary tract stones.

    Full Text Available Urinary metabolic disorders are one of the most common causes of stone formation in children. The purpose of this study was to evaluate the effect of urinary tract infections in the urinary metabolic characteristics as a risk factor in the incidence of urolithiasis. This case-control study was conducted in 222 children with urolithiasis in the range of 6 months to 16 years old in Sanandaj, Kurdistan, Iran during 2012-14. Patients were divided into two groups based on those with urinary tract infection and without urinary tract infection. Then, urine samples were collected from both groups, and levels of calcium, oxalate, citrate, uric acid, creatinine, and cysteine were measured. The collected information was analyzed using software SPSS (version 16. The ratio Average levels of calcium, magnesium, oxalate, cysteine, uric acid to creatinine in urine showed no significant difference between two groups based on statistical analysis. However, the amount of citrate to creatinine in children with urinary tract infection and urolithiasis was clearly less P=0.01. The results of this study show that the urinary tract infection cannot change the urinary metabolic characteristics, but it can be considered as a risk factor in kidney stone formation due to the reduced amount of citrate in the urine.

    Onset of canine transitional cell carcinoma (TCC) and prostatic carcinoma (PCA) is usually insidious with dogs presenting at an advanced stage of the disease. A biomarker that can facilitate early detection of TCC/PCA and improve patient survival would be useful. S100A8/A9 (calgranulin A/B or calprotectin) and S100A12 (calgranulin C) are expressed by cells of the innate immune system and are associated with several inflammatory disorders. S100A8/A9 is also expressed by epithelial cells after malignant transformation and is involved in the regulation of cell proliferation and metastasis. S100A8/A9 is up-regulated in human PCA and TCC, whereas the results for S100A12 have been ambiguous. Also, the urine S100A8/A9-to-S100A12 ratio (uCalR) may have potential as a marker for canine TCC/PCA. Aim of the study was to evaluate the diagnostic accuracy of the urinary S100/calgranulins to detect TCC/PCA in dogs by using data and urine samples from 164 dogs with TCC/PCA, non-neoplastic urinary tract disease, other neoplasms, or urinary tract infections, and 75 healthy controls (nested case-control study). Urine S100A8/A9 and S100A12 (measured by species-specific radioimmunoassays and normalized against urine specific gravity [S100A8/A9 USG ; S100A12 USG ], urine creatinine concentration, and urine protein concentration and the uCalR were compared among the groups of dogs. S100A8/A9 USG had the highest sensitivity (96%) and specificity (66%) to detect TCC/PCA, with specificity reaching 75% after excluding dogs with a urinary tract infection. The uCalR best distinguished dogs with TCC/PCA from dogs with a urinary tract infection (sensitivity: 91%, specificity: 60%). Using a S100A8/A9 USG  ≥ 109.9 to screen dogs ≥6 years of age for TCC/PCA yielded a negative predictive value of 100%. S100A8/A9 USG and uCalR may have utility for diagnosing TCC/PCA in dogs, and S100A8/A9 USG may be a good screening test for canine TCC/PCA.

    To investigate the prevalence of lower urinary tract symptoms (LUTS) and urinary incontinence (UI) in elementary school aged children in Manisa. Dysfunctional Voiding and Incontinence Scoring System (DVIS) which was developed in Turkey is used. A total of 416 children, 216 (51.9%) male and 200 (48.1%) female were recruited in this study. Mean age of children was 10.35 ± 2.44 years (median10 years). Daytime UI frequency was 6.7% (28 child), nocturnal incontinence 16.6% (69 child) and combined daytime and nocturnal incontinence 4.1% (17 child). There was no statistically significant difference in the prevalence of nocturnal and or daytime UI between male and female gender. Mean DVIS score was 2.65 ± 3.95 and gender did not affect total DVIS points. The mean ages of achieving daytime bowel and bladder control were all significantly correlated with DVIS points. DVIS points were positively correlated with the history of UI of the family. Total points were increased when the father was unemployed. UI negatively influences health related quality of life of the family and child, so it is important that awareness of the UI and symptoms of lower urinary tract dysfunction.

    The urinary tract exits to a body surface area that is densely populated by a wide range of microbes. Yet, under most normal circumstances, it is typically considered sterile, i.e., devoid of microbes, a stark contrast to the gastrointestinal and upper respiratory tracts where many commensal and pathogenic microbes call home. Not surprisingly, infection of the urinary tract over a healthy person's lifetime is relatively infrequent, occurring once or twice or not at all for most people. For those who do experience an initial infection, the great majority (70% to 80%) thankfully do not go on to suffer from multiple episodes. This is a far cry from the upper respiratory tract infections, which can afflict an otherwise healthy individual countless times. The fact that urinary tract infections are hard to elicit in experimental animals except with inoculum 3-5 orders of magnitude greater than the colony counts that define an acute urinary infection in humans (105 cfu/ml), also speaks to the robustness of the urinary tract defense. How can the urinary tract be so effective in fending off harmful microbes despite its orifice in a close vicinity to that of the microbe-laden gastrointestinal tract? While a complete picture is still evolving, the general consensus is that the anatomical and physiological integrity of the urinary tract is of paramount importance in maintaining a healthy urinary tract. When this integrity is breached, however, the urinary tract can be at a heightened risk or even recurrent episodes of microbial infections. In fact, recurrent urinary tract infections are a significant cause of morbidity and time lost from work and a major challenge to manage clinically. Additionally, infections of the upper urinary tract often require hospitalization and prolonged antibiotic therapy. In this chapter, we provide an overview of the basic anatomy and physiology of the urinary tract with an emphasis on their specific roles in host defense. We also highlight the

    Although lower urinary tract dysfunction (LUTD) in patients with cerebral palsy (CP) has been previously documented by clinical observations and urodynamic tests, its correlation with upper urinary tract deterioration (UUTD) has not been demonstrated. This paper documents symptoms and urodynamic findings of LUTD and their relationship with UUTD in 33 children with CP. By sonography, 4 of these children were found to have UUTD. Age was found to correlate with UUTD, but gender difference and mental or motor functions did not. When comparing urinary symptoms with UUTD, incontinence (n = 31) did not correlate, but on the other hand symptoms of detrusor sphincter dyssynergia (interrupted voiding, urinary retention, hesitancy; n = 5) and culture proven febrile urinary tract infections (n = 4) did. Abnormal urodynamics findings were not diagnostic. We conclude that, apart from incontinence, dysfunctional voiding symptoms and febrile urinary tract infections are valuable indicators of UUTD.

  7. Current concepts of molecular defence mechanisms operative during urinary tract infection.

    Mucosal tissues such as the gastrointestinal tract are typically exposed to a tremendous number of microorganisms and many of them are potentially dangerous to the host. In contrast, the urogenital tract is rather infrequently colonized with bacterial organisms and also devoid of physical barriers as a multi-layered mucus or ciliated epithelia, thereby necessitating separate host defence mechanisms. Recurrent urinary tract infection (UTI) represents the successful case of microbial host evasion and poses a major medical and economic health problem. During recent years considerable advances have been made in our understanding of the mechanisms underlying the immune homeostasis of the urogenital tract. Hence, the system of pathogen-recognition receptors including the Toll-like receptors (TLRs) is able to sense danger signalling and thus activate the host immune system of the genitourinary tract. Additionally, various soluble antimicrobial molecules including iron-sequestering proteins, defensins, cathelicidin and Tamm-Horsfall protein (THP), as well as their role for the prevention of UTI by modulating innate and adaptive immunity, have been more clearly defined. Furthermore, signalling mediators like cyclic adenosine monophosphate (cAMP) or the circulatory hormone vasopressin were shown to be involved in the defence of uropathogenic microbes and maintenance of mucosal integrity. Beyond this, specific receptors e.g. CD46 or beta1/beta 3-integrins, have been elucidated that are hijacked by uropathogenic E. coli to enable invasion and survival within the urogenital system paving the way for chronic forms of urinary tract infection. Collectively, the majority of these findings offer novel avenues for basic and translational research implying effective therapies against the diverse forms of acute and chronic UTI.

    Many theories have been proposed for the coexistence of constipation and lower urinary tract dysfunction (LUTD), such as bladder compression from a distended rectum and stimulation of sacral reflexes from a full rectum. In these cases, successful treatment of constipation should result in resolution of bladder symptoms. Some children have refractory constipation and others respond well to treatment, but once treatment is discontinued most children relapse back into their constipation. This may indicate the existence of a defect in colon motility, with a persistent peristalsis problem. The existence of a common neuromuscular disorder should be the base for both bladder and bowel dysfunction (BBD). To study colonic transit time (CTT) in children and adolescents with refractory constipation and lower urinary tract symptoms (LUTS). A total of 15 children (mean age 9.7 years) with refractory constipation and LUTS were evaluated with: standardized medical history; physical examination; bladder and bowel diaries; Bristol stool scale; Rome III criteria; Dysfunctional Voiding Scoring System (DVSS); ultrasound examination of the kidneys and urinary tract, and measurement of rectal diameter; urodynamic evaluation; and a CTT study using radiopaque markers. Urodynamic features were abnormal in 13 out of 15 children: 10 (66.7%) presented with detrusor overactivity (DO) and voiding dysfunction (VD), two (16.7%) had isolated DO, and one (8.3%) had a VD. The CTT study was abnormal in 12 out of 15 children: nine (60%) presented with slow transit constipation, three (20%) had outlet obstruction, and three (20%) had a normal CTT study. When comparing CTT and LUTD, nine (100%) children with slow transit constipation (STC) and three (50%) with no STC had DO (P = 0.04). Seven (77.8%) children with STC and three (50%) with no STC had VD (P = 0.29). The DVSS scores ranged from 6 to 21. The subgroup with STC had a DVSS score that was significantly higher than that of the subgroup with

    Full Text Available Jürgen Pannek, Jens Wöllner Neuro-Urology, Swiss Paraplegic Center, Nottwil, Switzerland Introduction: Urinary tract infections (UTIs are one of the most common morbidities in persons with neurogenic lower urinary tract dysfunction (NLUTD. They are associated with a significant morbidity and mortality, and they affect the quality of life of the affected patients. Diagnosis and treatment of UTI in this group of patients are challenging. In this review, the current strategies regarding diagnosis, treatment, and prevention are summarized. Diagnostics: it is important to correctly diagnose a UTI, as treatment of bacteriuria should strictly be avoided. A UTI is defined as a combination of laboratory findings (leukocyturia and bacteriuria and symptoms. Laboratory findings without symptoms are classified as asymptomatic bacteriuria. Routine urine screening is not advised. Treatment: Only UTI should be treated; treatment of asymptomatic bacteriuria is not indicated. Prior to treatment, urine for a urine culture should be obtained. Antibiotic treatment for ~7 days is advised. Prevention: In recurrent UTI, bladder management should be optimized and morphologic causes for UTI should be excluded. If UTIs persist, medical prophylaxis should be considered. Currently, no prophylactic measure with evidence-based efficacy exists. Long-term antibiotic prophylaxis should be used merely as an ultimate measure. Among the various mentioned innovative approaches for UTI prevention, bacteriophages, intravesical instillations, complementary and alternative medicine techniques, and probiotics seem to be most promising. Conclusion: Recently, several promising innovative options for UTI prophylaxis have been developed which may help overcome the current therapeutic dilemma. However, further well designed studies are necessary to evaluate the safety and efficacy of these approaches. Keywords: neurogenic lower urinary tract dysfunction, spinal cord injury, prophylaxis

    We investigated the outcomes and quality of life measures in men who underwent cystectomy and urinary diversion for devastating lower urinary tract toxicity after prostatic radiotherapy and/or cryotherapy for the treatment of prostate cancer. Records of patients who underwent cystectomy and urinary diversion for the management of a devastated lower urinary tract following prostatic radiotherapy or cryotherapy were reviewed retrospectively. A postoperative, retrospective quality of life (QOL) survey was designed specific to this patient subset and obtained by telephone interview. Extirpative surgery with urinary diversion for management of a devastated lower urinary tract was performed on 15 patients with a mean age of 72 years (range 63-82). Toxicities leading to bladder removal included bladder neck contractures, prostatic necrosis, incontinence, osteomyelitis, bladder calculi, fistulae, urethral strictures, abscesses, necrotizing fasciitis, and radiation/hemorrhagic cystitis. The mean number of failed conservative, minimally invasive interventions per patients prior to cystectomy was 3.7 (range 1-12). The average time period from major complication following radiotherapy/cryotherapy to cystectomy was 29.1 months (range 5-65). The QOL survey showed all of the patients who completed the survey (n = 13) would undergo the procedure again and 11 (85%) would have undergone the procedure an average of 13.2 months sooner (range 5-36). Toxicities secondary to prostatic radiotherapy or cryotherapy may be debilitating. Our results demonstrate that cystectomy with urinary diversion can improve QOL in patients with a devastated lower urinary tract.

    2016-06-01

    Full Text Available Vesicoureteral reflux (VUR is the most common underlying etiology responsible for febrile urinary tract infections (UTIs or pyelonephritis in children. Along with the morbidity of pyelonephritis, long-term sequelae of recurrent renal infections include renal scarring, proteinuria, and hypertension. Treatment is directed toward the prevention of recurrent infection through use of continuous antibiotic prophylaxis during a period of observation for spontaneous resolution or by surgical correction. In children, bowel and bladder dysfunction (BBD plays a significant role in the occurrence of UTI and the rate of VUR resolution. Effective treatment of BBD leads to higher rates of spontaneous resolution and decreased risk of UTI.

    To assess urinary symptoms associated with urinary tract infection (UTI) in a urogynecologic population of women. In this cohort study, we enrolled 150 urogynecologic patients who completed the validated UTI Symptom Assessment questionnaire and contributed transurethral catheterized urine samples. The primary measure (UTI diagnosis) was defined in three ways. Self-report (a nonculture-based UTI diagnosis) was defined by a yes or no response to the query "Do you think you have a UTI?" Two culture-based UTI diagnoses also were analyzed: standard urine culture (10 colony-forming units [CFU]/mL or greater) and enhanced quantitative urine culture (10 CFU/mL or greater) of any uropathogen. Statistical analyses were performed on patient demographics and urinary symptom prevalence among patient groups. Although the presence of the urinary symptoms of frequency and urgency (respectively) differ somewhat between UTI-positive and UTI-negative women (self-report [P=.005 and Purinary symptoms assessed by the UTI Symptom Assessment questionnaire compared with women not reporting dysuria (frequency P=.001, urgency P=.006, dysuria P<.001). Our findings show that, in women seeking urogynecologic care, the presence of frequency and urgency of urination does not confirm a culture-based UTI diagnosis. Instead, clinicians can more readily detect UTI using the presence of dysuria, which more effectively discriminates UTI-positive and UTI-negative individuals, regardless of the culture-based method used to diagnose UTI.

    To analyze the related influencing factors of urinary tract infection in patients undergoing transurethral resection of the prostate (TURP). A total of 343 patients with benign prostatic hyperplasia admitted to this hospital from January 2013 to December 2016, were selected and treated by TURP. Patients were divided into infection group and non-infection group according to the occurrence of urinary tract infection after operation. The possible influencing factors were collected to perform univariate and multivariate logistic regression analysis. There were 53 cases with urinary tract infection after operation among 343 patients with benign prostatic hyperplasia, accounting for 15.5%. The univariate analysis displayed that the occurrence of urinary tract infection in patients undergoing TURP was closely associated with patient's age ≥ 65 years old, complicated diabetes, catheterization for urinary retention before operation, no use of antibiotics before operation and postoperative indwelling catheter duration ≥ 5 d (p urinary tract infection in patients receiving TURP (p urinary tract infection after TURP, while preoperative prophylactic utilization of anti-infective drugs can reduce the occurrence of postoperative urinary tract infection.

    Although infection remains a major aetiological factor in stone formation, especially in boys, there is increasing recognition of the numbers of children affected by a metabolic predisposition to stone formation and this proportion appears to be increasing, and hence every child who presents with urolithiasis should undergo a metabolic work-up. In a study performed in the UK, 44% of children had a metabolic abnormality, 30% were classified as infective, and 26% idiopathic. A study from Texas found a similar pattern. Coexisting urinary tract infection can of course mask underlying metabolic causes. The rate of stone recurrence is lower in children compared to adults and the majority of stone disease is now managed, as in adults, by lithotripsy or endourological techniques; open surgery has decreased dramatically.

    A trial was carried out in 30 patients to assess the effectiveness of indanyl carbenicillin in acute or chronic urinary tract infections, many of which were complicated by a pathological urological or medical condition. In all patients, infection was due to a single species of pathogen: E. coli (19), Proteus (6), and Pseudomonas (5). Oral doses of 1 g indanyl carbenicillin were given 6-hourly for an average of 10 days. Results showed a clinical and bacteriological cure in 13 (43.8%) patients. In 6 patients, although there was initial clinical improvement, the pathogen developed resistance during therapy. In 7 patients, there was super-infection with another organism. Four patients were withdrawn early in treatment because of side-effects, mainly gastrointestinal in origin. Indanyl carbenicillin proved very effective in eradicating all strains of Proteus and Pseudomonas and 12 (70.6%) of the 17 strains of E. coli in patients completing the full course of treatment.

    The diagnostic sensitivity of Ultrasound (US) was studied in 142 children with suspected kidney and urinary tract malformations. According to the clinical tests performed the patients underwent excretory urography (EU) and/or voiding cystouretrography (VCU); the results were compared to US findings. In the 75 patients with malformations, US proved to be extremely sensitive in abdominal renal ectopies, in ''horseshoe'' kidney, and in congenital obstructions of the ureteropelvic and vesico-ureteral junctions. US showed a higher sensitivity than EU in identifying multicystic kidney and in most cases of hypodysplasia. On the other hand, VCU was more accurate in vesico-ureteral reflux studies; US should thus be used in the follow-up of the patients undergoing medical therapy. EU must however be considered as the most important tool in the evaluation of early renal injuries and their possible development

    As age and sex affect the function of the lower urinary tract, we studied the characteristics of adrenergic and cholinergic receptors in various parts of lower urinary tract smooth muscle of young (6 months) and old (4 1/2-5 years) male and female rabbits. Saturation experiments performed with [3H]prazosin, [3H]yohimbine, [3H]dihydroalprenolol and [3H]quinuclidinyl benzylate in rabbit bladder base, bladder dome and urethra indicate the presence of regional, sex- and age-related differences in the density of alpha-1, alpha-2, and beta adrenergic and muscarinic cholinergic receptors. Alpha-2 adrenergic receptor density is considerably higher in the female than in the male urethra of both age groups, whereas the higher density of beta adrenergic receptors in the female than in the male bladder base is observed only in the younger animals. The density of muscarinic receptors is higher in bladder dome than in bladder base or urethra in young rabbits of both sexes. In the old animals, the density of muscarinic receptors in bladder base increases to the level observed in bladder dome. Inhibition experiments with selective adrenergic agonists and antagonists indicate that the pharmacological profiles of alpha-2 adrenergic receptors in the urethra and beta adrenergic receptors in the bladder dome and bladder base are similar in both sexes and at both ages. Beta-2 adrenergic receptors are shown to be predominant in bladder base and bladder dome of rabbits. Parallel studies in rabbit urethra, adult rat cortex and neonatal rat lung show that the urethral alpha-2 adrenergic receptors are of the alpha-2A subtype

    Full Text Available We aimed to investigate the role of urinary bladder shape which may potentially change with advancing age, increased waist circumference, pelvic ischemia, and loosening of the urachus on bladder emptying and UFR. We retrospectively investigated the medical records of 76 men. The patients were divided into two groups according to bladder shapes in MRI scan (cone and spheric shapes. There was a significant difference between the two groups in terms of IPSS, Qmax, Qave, and waist circumference. A positive correlation has been demonstrated between mean peak urinary flow rate measured with UFM and mean flow rate calculated using the CP. There was a significant difference between mean urinary flow rates calculated with CP of cone and sphere bladder shapes. The change in the bladder shape might be a possible factor for LUTS in men and LUTS may be improved if modifiable factors including increased waist circumference and loosening of the urachus are corrected.

    The lower urinary tract (LUT) stores and evacuates urine. It is controlled by autonomic, somatic and sensory innervation. Pharmacotherapy has been developed to optimize neural control of the LUT in pathologic states. The bladder can be overactive or underactive. For overactive bladder, medications targeting various receptors include i) antimuscarinics, ii) mixed-action drugs, iii) β-adrenergic receptor agonists and iv) other medications. There is no effective pharmacotherapy for underactive bladder, although medications have been used with limited success, including i) muscarinic receptor agonists, ii) anticholinesterase inhibitors and iii) α-adrenergic receptor antagonists. At the level of the outlet, there can be decreased resistance resulting in stress urinary incontinence (SUI) or increased resistance resulting in bladder outflow obstruction (BOO). The classes of medications for SUI include i) α-adrenergic receptor agonists, ii) β-adrenergic receptor agonists and iii) antidepressants. Medications used to treat BOO include i) α-adrenergic receptor antagonists, ii) 5-α reductase inhibitors, iii) benzodiazepines, iv) baclofen and v) PDE inhibitors. Pharmacotherapy for the LUT must be individualized based on degree of bother, medication side-effect profile, concomitant comorbidities, current medication regimen, and insurance coverage. This review describes current medical therapies for the LUT.

    The prevalence of lower urinary tract (LUT) dysfunction in peripheral nervous system (PNS) disorders is larger than in comparable control populations. This is particularly true for polyneuropathies with autonomic nervous system involvement, and for localized lesions with LUT innervation. LUT symptoms may be the guide to the diagnosis of processes localized in the lumbosacral spinal canal (as in cauda equina syndrome), and in the pelvis. Typical LUT dysfunctions (LUTD) caused by PNS involvement include bladder and sphincter hypoactivity with poor emptying, and incontinence. Paradoxically, bladder overactivity may also occur in pure PNS lesions. The acute cauda equina syndrome is an emergency requiring magnetic resonance imaging and surgery; in chronic neurogenic LUTD due to PNS involvement, the diagnosis of the lesion may be clarified by clinical neurophysiologic testing. Other important causes of neurogenic LUT dysfunction are perineoabdominal and pelvic surgeries. Surgeons are devising nerve-sparing techniques to prevent such major and often persistent complications in patients who are otherwise cured of the underlying disease. LUTD significantly affects the quality of life in patients and may lead to recurring urinary infections and upper urinary tract involvement. Thorough assessment of LUT function by urodynamics may be necessary in patients who are not improved by simple conservative measures. © 2015 Elsevier B.V. All rights reserved.

    Establishment of asymptomatic bacteriuria (ABU) with Escherichia coli 83972 is a viable prophylactic alternative to antibiotic therapy for the prevention of recurrent bacterial urinary tract infection in humans. Approximately 2 × 10(8) viable E. coli 83972 cells were introduced into the bladder of six healthy female dogs via a sterile urinary catheter. The presence of pyuria, depression, stranguria, pollakiuria and haematuria was documented for 6 weeks and urinalysis and aerobic bacterial cultures were performed every 24-72 h. Pyuria was present in all dogs on day 1 post-inoculation and 4/6 dogs (67%) had a positive urine culture on this day. Duration of colonization ranged from 0 to 10 days (median 4 days). Four dogs were re-inoculated on day 20. Duration of colonization following the second inoculation ranged from 1 to 3 days. No dog suffered pyrexia or appeared systemically unwell but all dogs initially exhibited mild pollakiuria and a small number displayed gross haematuria and/or stranguria. By day 3 of each trial all clinical signs had resolved. Persistent bacteriuria was not achieved in any dog but two dogs were colonized for 10 days following a single inoculation. Further research is required to determine whether establishment of ABU in dogs with recurrent urinary tract infection is a viable alternative to repeated doses of antimicrobial agents.

    Functional movement disorders (FMD) are not associated with the kind of structural or biochemical alterations seen in other movement disorders and therefore would be unlikely to be associated with lower urinary tract (LUT) dysfunction. However, LUT symptoms have been observed in patients with FMD. To evaluate the frequency and pattern of LUT symptoms, their possible nature and the impact they have on the quality of life of patients with FMD. The clinical records of patients with FMD were reviewed retrospectively and patients reporting LUT symptoms were invited to complete standardised validated questionnaires-Urinary Symptom Profile (USP) and Short Form-Qualiveen (SFQ). Management of LUT dysfunction was also reviewed. Out of the 150 patients with clinically established (n=97) or probable (n=53) FMDs, thirty (20%) self-reported LUT symptoms. Twenty two of these completed the USP and SFQ questionnaires. Overactive bladder symptoms were most commonly reported (n=14; 63.6%). Patients with fixed dystonia reported more severe LUT symptoms and had higher SFQ scores as compared to patients with other FMDs (p=0.01). Five patients with significant LUT symptoms had been referred to uroneurology. Of them, three had urinary retention managed with sacral neuromodulation, two had overactive bladder and were managed conservatively. LUT dysfunction can be seen in 20% patients with FMD. Patients with fixed dystonia are more likely to report LUT dysfunction which can be severe. It may be advisable to ask for LUT symptoms in all patients with FMD and be more proactive in referring them for specialist investigation and treatment. Copyright © 2016 Elsevier B.V.

    To evaluate the existing data regarding the use of cranberry products for the prevention of urinary tract infections (UTIs) in pediatric patients. A literature search of Medline databases from 1966 to June 2015 was conducted. The databases were searched using the terms "pediatrics," "children," "cranberry," "cranberry juice," and "urinary tract infections." The identified trials were then searched for additional references applicable to this topic. A total of 8 clinical trials were identified that examined the use of cranberry products, mostly juice, for the prevention of UTIs in children. Three trials examined the use in otherwise healthy children. Five trials examined the use in pediatric patients with underlying urogenital abnormalities of which 2 compared cranberry to antibiotics. In healthy pediatric patients, cranberry use was associated with a reduction in the overall number of UTIs and a decrease in the number of antibiotic days per year for UTI treatment. In patients with urogenital abnormalities, results were conflicting, with some studies showing no reduction in UTIs compared with placebo, but others demonstrating a significant reduction. However, cranberry products had similar efficacy when compared with both cefaclor and trimethoprim. All studies used a wide variety of doses and frequencies of cranberry, making specific product recommendations difficult. Cranberry appears effective for the prevention of UTIs in otherwise healthy children and is at least as effective as antibiotics in children with underlying urogenital abnormalities. However, recommendations for cranberry dosing and frequency cannot be confidently made at this time. Larger, well-designed trials are recommended. © The Author(s) 2015.

    Full Text Available Aim: Urinary tract infection (UTI is one of the most common diseases of urogenital tract in children. Detecting predisposing factors for UTI takes an important place in managing patients with UTI. Recently, a few studies emphasized on idiopathic hypercalciuria (IH as a predisposing factor for UTI and dysfunctional voiding. Therefore, we carried out a survey to find out whether non-calculus IH is a contributing factor in children with the first attack of pyelonephritis. Materials and Methods: This is a case-control study carried out on 60 children aged 2-11 years admitted at St Al-Zahra hospital, Isfahan, Iran, with the first episode of upper UTI and 200 age- and gender-matched normal healthy children between September 2003 and February 2005. We used second fasting spot urine sample to measure calcium and creatinine. Two urine samples were obtained one week apart to increase the accuracy of measurement. All samples were collected after at least 6 weeks of completing the treatment course of pyelonephritis. Ultrasound examination and VCUG were performed in all patients before entering the survey as case group to rule out obstruction and VUR. Results: Mean age of case and control group were 4.86 ± 3.08 years and 4.22 ± 2.9 years, respectively. The mean calcium to creatinine ratio (Ca/Cr in case and control group were 0.308 ± 0.21 and 0.208 ± 0.12 mg/mg, respectively, P < 0.001. The difference between the mean values of these two groups was significant only in age group ≤6 years, P < 0.0001 and odds ratio was 2.1 (95% CI 1.03-7.8. After determining the mean values of urine Ca/Cr ration according to both age groups and gender, it was cleared that only significant difference was related to male < 6 years. Conclusion: The likelihood of hypercalciuria should be assessed especially in male children with UTI and without any urinary tract obstruction.

    Cathelicidin (LL-37) and human β-defensin 1 (hBD-1) are important components of the innate defense in the urinary tract. The aim of this study was to characterize whether these peptides are important for developing uncomplicated Escherichia coli urinary tract infections (UTIs......). This was investigated by comparing urinary peptide levels of UTI patients during and after infection to those of controls, as well as characterizing the fecal flora of participants with respect to susceptibility to LL-37 and in vivo virulence. Forty-seven UTI patients and 50 controls who had never had a UTI were...... indicate that the concentration of LL-37 in the urinary tract and low susceptibility to LL-37 may increase the likelihood of UTI in a complex interplay between host and pathogen attributes....

    The National Institute of Clinical Excellence published guidelines in 2010 recommending the use of cystoscopy to investigate profound lower urinary tract symptoms (pLUTS), recurrent urinary tract infection (rUTI), and pain in men. Currently, there are no equivalent guidelines for women. We aimed to examine the diagnostic performance of flexible cystoscopy (FC) when it is used in this context in both men and women. Results of all outpatient FCs undertaken in our department between April 2009 and March 2010 were examined retrospectively. Patients undergoing FC for the investigation of pLUTS, rUTI, or pain were included. Diagnostic performance was calculated, which was defined as the number of patients receiving a diagnosis of a clinically relevant abnormality at FC divided by the total number of patients undergoing FC for this indication. Of the 1809 patients who underwent FC during the study period, 113 underwent FC to investigate pLUTS, rUTI, or pain. Diagnostic performance was 11.5% (n=13), being 11.4%, 19.2%, and 0% in those with pLUTS, rUTI, and pain, respectively. Bladder cancer was diagnosed in one (0.9%) patient who underwent FC to investigate pLUTS but also had nonvisible hematuria. Urethral stricture was diagnosed in nine (8.0%) cases and intravesical calculi in four (3.5%) cases. Clinically relevant abnormalities were found in 11.5% of patients with pLUTS, rUTI, or pain, supporting recently published NICE guidelines recommending cystoscopy in patients with pLUTS or rUTI. Of the 17 patients who were investigated for pain, none was found to have clinically relevant abnormalities; further studies are needed to define the clinical utility of FC in these cases.

    Epidemiological studies have demonstrated rates of lower urinary tract (LUT) symptoms in school-aged children as high as 20%. Symptoms of LUT may have significant social consequences. The diagnosis of LUT symptoms in children is mainly based on the subjective impression, and it is therefore important to translate the clinical impression into a structured LUT terminology. To have a view, as a pediatric urologist and a urologist, of the LUT terminology proposed by the Standardization Committee of the International Children Continence Society. In addition to the known LUT terminology conditions that are mainly functional, we propose to add specific urological malformations due to congenital or acquired urological conditions, leading to LUT symptoms. In addition to the opinion-based statements and practical clinical suggestions, we have added recent literature to support the statements and suggestions. LUT symptoms in children can be from a functional or an anatomical origin. As the diagnosis is often made on the basis of subjective and variable information, experience of the medical caretaker is also important to allow categorization of the condition of the child into a well-structured LUT terminology. Medical caretakers should be aware of possible evidence-based diagnostic tools and be able to follow guidelines and algorithms to come to the correct diagnosis and condition of the child to allow one to distinguish functional from congenital or acquired anatomical LUT conditions. Up to 20% of school-aged children can have wetting problems. Some wetting problems can be temporary, due to the young age, stress, psychological problems, or other associated problems such as bowel dysfunction. However, some wetting problems in children are due to a condition of the kidneys, bladder, or elsewhere in the urinary tract since they were born, and should be well investigated, as in most such situations the LUT problems could be treated surgically.

    The first urinary tract infection can be a marker of a urinary tract anomaly, mainly vesicoureteral reflux. The aim of this work was to determine the association between isolated enterobacteria with the presence and grade of vesicoureteral reflux in neonatal patients with their first urinary tract infection. A retrospective, observational and analytic study of newborns, who were admitted to the Neonatal Department, University Pediatric Hospital "Juan Manuel Márquez," in Havana, Cuba, from 1992 to 2013 was conducted. The causal microorganism of urinary tract infection was from the Enterobacteriaceae family. They were evaluated by radio imaging. The association between the presence and grade of vesicoureteral reflux with the causal microorganism of the urinary tract infection was analyzed. Newborn infants with urinary tract infection (450) were studied. Bacterial isolations in the urine cultures corresponded to E. coli in 316 cases (70.2%). The prevalence of vesicoureteral reflux was 18.2%. The presence of bacteria corresponding to the Enterobacteriaceae family (other than E. coli) had significant risk association with vesicoureteral reflux (OR: 2.02; p urinary tract infection. However, an association between the isolation of a microorganism of the Enterobacteriaceae family different to E. coli with the presence of vesicoureteral reflux and mainly with higher grades of vesicoureteral reflux exists.

    2014-07-01

    Urinary tract infections are a heterogeneous group of disorders, involving infection of all or part of the urinary tract, and are defined by bacteria in the urine with clinical symptoms that may be acute or chronic. Approximately 1 million urinary tract infections are treated every year in United States emergency departments. The female-to-male ratio is 6:1. Urinary tract infections are categorized as upper versus lower tract involvement and as uncomplicated versus complicated. The emergency clinician must carefully categorize the infection and take into account patient host factors to optimally treat and disposition patients. A working knowledge of local or at least national susceptibility patterns of the most likely pathogens is essential. A variety of special populations exist that require special management, including pregnant females, patients with anatomic abnormalities, and instrumented patients.

    To identify the potential risk factors for urinary tract infections following midurethral sling procedures. 556 women who underwent midurethral sling procedure due to stress urinary incontinence over a four-year period were reviewed in this retrospective study. Of the study population, 280 women underwent TVT procedures and 276 women underwent TOT procedures. Patients were evaluated at 4-8 weeks postoperatively and were investigated for the occurrence of a urinary tract infection. Patients who experienced urinary tract infection were defined as cases, and patients who didn't were defined as controls. All data were collected from medical records. Multivariate logistic regression model was used to identify the risk factors for urinary tract infection. Of 556 women, 58 (10.4%) were defined as cases while 498 (89.6%) were controls. The mean age of women in cases (57.8±12.9years) was significantly greater than in controls (51.8±11.2years) (purinary tract infection, concomitant vaginal hysterectomy and cystocele repair, TVT procedure and postoperative postvoiding residual bladder volume ≥100ml were more common in cases than in controls. However, in multivariate regression analysis model presence of preoperative urinary tract infection [OR (95% CI)=0.1 (0.1-0.7); p=0.013], TVT procedure [OR (95% CI)=8.4 (3.1-22.3); p=0.000] and postoperative postvoiding residual bladder volume ≥100ml [OR (95% CI)=4.6 (1.1-19.2); p=0.036] were significant independent risk factors for urinary tract infection following midurethral slings CONCLUSION: Urinary tract infection after midurethral sling procedures is a relatively common complication. The presence of preoperative urinary tract infection, TVT procedure and postoperative postvoiding residual bladder volume ≥100ml may increase the risk of this complication. Identification of these factors could help surgeons to minimize this complicationby developing effective strategies. Copyright © 2017. Published by Elsevier B.V.

    Obesity and physical activity have been posited as modifiable risk factors to delay lower urinary tract symptom progression. In this study we determined the independent associations of physical activity and obesity with lower urinary tract symptoms at followup among white and African-American men. Male participants 40 to 79 years old were identified from the Southern Community Cohort Study, a prospective cohort based in the southeastern United States. Baseline data collection included a validated physical activity questionnaire, height and weight, health history and other information. We excluded participants with a history of or medication use for benign prostatic hyperplasia or prostate cancer. Participants (7,318, 60% African-American) completed the International Prostate Symptom Score approximately 5 years after baseline. Patients with an International Prostate Symptom Score greater than 8 or 20 were classified as having moderate or severe lower urinary tract symptoms, respectively, at followup. Multivariable logistic regression was used to assess the relationships among obesity, physical activity and lower urinary tract symptoms. Moderate to severe lower urinary tract symptom severity at followup was significantly associated with a body mass index of 35 kg/m(2) or more (OR 1.38, 95% CI 1.17-1.63). Similarly the lowest categories of physical activity were associated with the onset of severe lower urinary tract symptoms in men with a normal body mass index (OR 1.38, 95% CI 1.05-1.82). These associations were independent of race. Severe obesity is associated with an increased risk of lower urinary tract symptoms at followup, while physical inactivity may permit progression of lower urinary tract symptoms in normal weight men regardless of race. These variables should be considered in future research into modifiable risk factors for lower urinary tract symptoms. Copyright © 2011 American Urological Association Education and Research, Inc.

    We constructed a risk prediction instrument stratifying patients with primary vesicoureteral reflux into groups according to their 2-year probability of breakthrough urinary tract infection. Demographic and clinical information was retrospectively collected in children diagnosed with primary vesicoureteral reflux and followed for 2 years. Bivariate and binary logistic regression analyses were performed to identify factors associated with breakthrough urinary tract infection. The final regression model was used to compute an estimation of the 2-year probability of breakthrough urinary tract infection for each subject. Accuracy of the binary classifier for breakthrough urinary tract infection was evaluated using receiver operator curve analysis. Three distinct risk groups were identified. The model was then validated in a prospective cohort. A total of 252 bivariate analyses showed that high grade (IV or V) vesicoureteral reflux (OR 9.4, 95% CI 3.8-23.5, p urinary tract infection (OR 5.3, 95% CI 1.1-24.7, p = 0.034) and female gender (OR 2.6, 95% CI 0.097-7.11, p urinary tract infection. Subgroup analysis revealed bladder and bowel dysfunction was a significant risk factor more pronounced in low grade (I to III) vesicoureteral reflux (OR 2.8, p = 0.018). The estimation model was applied for prospective validation, which demonstrated predicted vs actual 2-year breakthrough urinary tract infection rates of 19% vs 21%. Stratifying the patients into 3 risk groups based on parameters in the risk model showed 2-year risk for breakthrough urinary tract infection was 8.6%, 26.0% and 62.5% in the low, intermediate and high risk groups, respectively. This proposed risk stratification and probability model allows prediction of 2-year risk of patient breakthrough urinary tract infection to better inform parents of possible outcomes and treatment strategies.

    The incidence of symptomatic urinary tract infection following reflux resolution by endoscopic injection is unclear. We determined the occurrence of febrile and nonfebrile urinary tract infections, and factors relating to development of infection after reflux correction with dextranomer/hyaluronic acid injection. We identified 175 patients with more than 6 months of followup after successful dextranomer/hyaluronic acid injection by one of us (WS) to resolve vesicoureteral reflux. Of these patients data regarding post-injection symptomatic urinary tract infection could be obtained from parents and/or primary care physicians and urological records in 167, who comprised the study group. All patient reported infections were additionally verified by review of medical records. Univariate and multivariate logistic regression analyses were done, evaluating factors including gender, age, voiding dysfunction, reflux grade, unilateral vs bilateral reflux, number of pretreatment infections, number of infections within 12 months of injection and febrile vs nonfebrile urinary tract infection in predicting the likelihood of post-injection urinary tract infection. Urinary tract infection occurred in 159 patients (95%) before injection, and was febrile in 82%. With a median followup after reflux correction of 32 months (range 7 to 53) symptomatic infections developed in 40 children (24%), of which half were febrile. Multivariate analysis showed that the number of preoperative urinary tract infections best predicted the likelihood of infection after dextranomer/hyaluronic acid injection. Nearly half of the patients with febrile urinary tract infection undergoing followup cystography had recurrent reflux. Patients with more than 3 pre-injection infections were 8.5 times more likely than those with 1 pre-injection infection to have post-injection symptomatic urinary tract infection.

    Escherichia coli is the most common organism associated with asymptomatic bacteriuria (ABU) in humans. In contrast to uropathogenic E. coli (UPEC) that cause symptomatic urinary tract infection, very little is known about the mechanisms by which these strains colonize the urinary tract. Here, we...... have investigated the biofilm-forming capacity on abiotic surfaces of groups of ABU strains and UPEC strains in human urine. We found that there is a strong bias; ABU strains were significantly better biofilm formers than UPEC strains. Our data suggest that biofilm formation in urinary tract infectious...

    Aerococcus urinae is a microorganism responsible for urinary tract and blood stream infections which are rarely reported in clinical practice. However, it has been proposed that the infrequency of such reports may be partially due to difficulties related to pathogen identification. We present here a case of an elderly male patient with urinary tract infection where A. urinae was initially not identified by a private microbiology laboratory. Our report highlights the need to consider A. urinae as a causative agent of urinary tract infections because if not identified and properly treated it may lead to endocarditis or septicemia.
