PURPOSE OF REVIEW The underlying cause of catheter-associated urinary tract infection is biofilm formation by uropathogens on the urinary catheter. Biofilm is a relatively new concept in medicine, and current measures to prevent biofilm formation are inadequate. Considerable work is being done in this area, but little clinical progress has been made. The purpose of this review is to analyze rec...

the product biofilm by e.coli strain can cause serious problem for human health. catheter is considered to be s suitable place for colonization of microorganisms, so that in %5-10 of patients who used catheter for only one day and also in all patients who used it for over 28 days, this colonization of bacteria is observed on catheter. this study is come out in order to compare biofilm formation...

The use of a urinary bladder catheter in the perioperative period for patients undergoing total knee arthroplasty is controversial. In the current study, two bladder management protocols were studied. One group of patients had an indwelling catheter inserted into the bladder before total knee arthroplasty. The other group of patients was observed and treated for urinary retention as necessary. ...

OBJECTIVE To evaluate the risk factors for postoperative urinary retention in women who underwent vaginal hysterectomy for symptomatic pelvic organ prolapse. METHODS The medical records of 221 women who underwent vaginal hysterectomy with anterior and posterior colporrhapy were reviewed. Urinary retention after catheter removal was defined as the presence of at least one of the following thre...

OBJECTIVES To investigate incidence, rationales, related factors and outcomes for changing from appropriate catheter placement to inappropriate use among hospitalized older patients in the emergency department. METHODS A secondary analysis was adopted from a longitudinal study that was designed to follow the lifecycle of the urinary catheter among hospitalized older patients. Patients aged 65...

More than 75% of hospital-acquired or nosocomial urinary tract infections are initiated by urinary catheters, which are used during the treatment of 15-25% of hospitalized patients. Among other purposes, urinary catheters are primarily used for draining urine after surgeries and for urinary incontinence. During catheter-associated urinary tract infections, bacteria travel up to the bladder and ...

BACKGROUND Urinary tract infections (UTIs) are the most common nosocomial infection experienced by patients in United States hospitals and are responsible for significant morbidity and excess hospital costs. The purpose of this study was to determine the efficacy of a silver alloy, hydrogel-coated, urinary catheter in the prevention of catheter-associated UTI, to assess the cost effectiveness o...

Indwelling urinary catheters may act as a reservoir of bacteria and cause urinary tract infections. Removal of the bacteria adherent to a urinary catheter should reduce the incidence of catheter-associated urinary tract infections. Using several N-acylated amino acids with combinations of four different acyl residues, we investigated their efficacy in removing adherent bacteria from catheter ma...

BACKGROUND Indwelling urinary catheter duration is an important risk factor for catheter-associated urinary tract infections (CAUTIs). OBJECTIVE To audit patient-level postoperative catheter duration and measure the impact of its feedback to nursing staff on postoperative catheter duration and CAUTI rates. DESIGN Preobservational and postobservational study. SETTING Two surgical units at ...
