View clinical trials related to Urinary Tract Infections.
Filter by:This research project is designed to find out whether people who suffer repeated urinary tract infections (UTI) related to the need to empty their bladders intermittently with a fine plastic tube (catheter); a process called clean intermittent self-catheterisation (CISC), benefit from taking continuous daily low-dose antibiotics (antibiotic prophylaxis). The investigators estimate that about 40,000 people in the United Kingdom need to use CISC regularly to empty their bladder either because of nerve damage such as multiple sclerosis or because of failure of the bladder muscle to contract, and of these about 25% (10,000 people) suffer frequent UTI. One way to reduce this problem may be to take a small daily dose of antibiotics and the study aims to find out whether such treatment is effective and worthwhile both for the people who suffer the problem and for the National Health Service (NHS). The two options to be compared in the trial are firstly, a once daily preventive dose (prophylaxis) of an antibiotic routinely used for this purpose (either nitrofurantoin or trimethoprim or cefalexin), and secondly no prophylaxis. The investigators think that an overall decrease of 20% or more in the frequency of UTI would be large enough for future patients using CISC who get troublesome recurrent UTIs to be offered antibiotic prophylaxis routinely. The investigators will also assess any harm caused by continuous use of antibiotics, particularly side effects for those people taking them and changes in the resistance of bacteria to these antibiotics. The investigators can then work out whether the balance between the benefits and harms make the use of prophylaxis worthwhile to people carrying out CISC and for the NHS as a whole.
Urinary tract infection is most common serious bacterial infection in children who admit into the emergency department (ED). However the collection of urine from young children is time consuming process. So many children and their family guardian waste time until medical disposition established. In 2013, Maria Luisa Herreros Fernandez etc have suggested a new urine collection technique for newborn, that bladder and lumbar stimulation technique is fast and safe. The aim of this study is to determine clinical efficacy of bladder and lumbar stimulation technique (BLST) for pediatric patient in ED.
The investigators hypothesize that antibiotic therapy for asymptomatic bacteriuria in renal transplant patients does not have impact on the development of symptomatic urinary tract infection (UTI) or progression of renal impairment in patients during the first year after transplantation.
The efficacy of Solifenacin Succinate 5 mg as adjuvant therapy and levofloxacin (500 mg) for short-term treatment to reduce symptoms in patients with symptomatic non complicated urinary tract infection in females.
Background: Squamous metaplasia refers to the pathological transformation of the urothelium leading to non-keratinised stratified squamous metaplasia (N-KSM). Objective: To present the investigators experiences in the diagnosis and treatment of N-KSM of the urinary bladder in children.
The purpose of this cross over pilot study is to investigate the urinary catabolites of Proanthocyanidines (PACs) as biomarkers of cranberry extracts in healthy young women.
The objective this trial is to compare immediate and 12 hours postoperative removal of urinary catheter after elective cesarean section; and whether early removal is associated with lower risk of urinary infection compared with delayed catheter removal.
Although clean intermittent catheterization (CIC) remains the mainstay to ensure complete low-pressure bladder emptying in neurogenic bladder (NB) patients, this forms a vehicle for bacterial entry and colonization of the urinary tract, which can lead to recurrent urinary tract infection (RUTI) and renal damage. Up to 25% of NB patients on CIC suffer from RUTI and daily, low-dose antibiotic prophylaxis is widely prescribed to prevent these infections. Unfortunately, this therapeutic option is not evidence-based and can be associated with a higher risk of RUTI secondary to development of antibiotic resistance. In addition, many children suffer from a range of adverse reactions and emergence of drug resistant organisms. Moreover, recent studies have shown that antibiotics cause a major disruption in the human microbiome, potentially leading to long term major problems. Probiotics are live microorganisms, which when administered in adequate amounts confer a health benefit on the host. There is evidence that probiotics restore microbial homeostasis in the vagina, reduce the risk of pathogen ascension into the bladder, and modulate immunity to better protect the host. Probiotic strains, including Lactobacillus rhamnosus GR-1, Lactobacillus reuteri B-54 and RC-14, have been shown to be safe and efficacious in an oral formulation or as a vaginal suppository in improving the microbiota profile of the vagina and decreasing the risk of RUTI. Various mechanisms appear to be involved, including modulating antimicrobial and inflammatory defenses, up-regulating protective mucin production and reducing the pressure on pathogens to acquire antibiotic resistance genes. A randomized trial comparing probiotics to antibiotic prophylaxis in children with vesicoureteric reflux showed equivalent reduction in the incidence of RUTI and development of new renal scarring. In addition, down regulation of inflammatory cytokines can potentially favorably alter bladder function and prevent bladder fibrosis. Investigators at London Health Sciences Centre (LHSC) have the opportunity to acquire clinical data that would strengthen the case for probiotics to be integrated into pediatric urology practice for managing CIC and RUTI. This would be the first such study in pediatric NB patients. The main objective of this study is to determine whether the use of probiotics (lactobacilli) can decrease the impact of adverse side effects and the antibiotic resistance that is seen with the prolonged use of antibiotics for patients with neurogenic bladder conditions.
Prospective trial which includes instillation of intravesical hyaluronic acid in an attempt to reduce the incidence of urinary tract infections in patients after orthotopic neobladder reconstruction.
Hypothesis: Administration of corticoids (dexamethasone) together with the conventional antibiotherapy in the acute phase of a febrile urinary tract infection could reduce the risk of renal scarring after 6 months of the primo-infection. Primary objectives:To evaluate the reduction in incidence of renal scarring after 6 months of a acute pyelonephritis between the control group (conventional therapy plus placebo) and intervention group (conventional therapy plus dexamethasone. Design: Multicentre randomized clinical trial,placebo controled, including children between 2 months and 14 years with a acute pyelonephritis proven by a acute phase DMSA (dimethylsuccinic acid ). A total of 180 children in to parallel groups (intervention and placebo) will be included.
