In patients with indwelling bladder catheters for > 2 weeks, bacterial colonization is inevitable, leading to urinary tract infections or encrustations with subsequent catheter blockage.
The minimalist approach to transcatheter aortic valve replacement (TAVR) focuses on avoiding extraneous invasive measures. Data describing the clinical impact of routine indwelling urinary catheter (IUC) in TAVR patients is limited.
The use of invasive devices increases the risk of healthcare associated infections (HAI). The recent national HAI point prevalence survey secondary outcomes aimed to estimate the prevalence of patients with an indwelling urinary catheter device and vascular access devices; and also identify prevalence of those managed under transmission based precautions (TBP); and those colonised or infected with a multi drug resistant organism (MDRO).
Patients with acute traumatic cervical spinal cord injury (ATCSCI) have an increased risk of catheter-associated urinary tract infection (CAUTI). The effectiveness of silver alloy-coated silicone urinary catheters (SACC) in preventing CAUTI in ATCSCI is unknown and was the objective of this study.
Catheter-associated urinary tract infections (CAUTIs) account for 25% of all hospital-acquired infections. Neuro-critically ill patients are at 2-5 times greater risk of developing CAUTI because of increased use of indwelling urinary catheters due to neurogenic urinary retention.
This article discusses catheter maintenance solutions, the way they are supposed to be used and the way they actually are being used in primary and community care in the UK. It discusses the knowledge that community nursing staff have regarding these solutions and the need for further education.
An indwelling urinary catheter (IUC) is often inserted to manage bladder dysfunction, but its impact on prognosis is uncertain. We aimed to determine the association of IUC use on clinical outcomes after acute stroke in the international, multi-center, cluster crossover, Head Positioning in Acute Stroke Trial (HeadPoST).
To estimate whether nitrofurantoin prophylaxis decreases the incidence of culture-documented urinary tract infection for women with catheter-managed urinary retention after pelvic reconstructive surgery.
We introduce our novel procedure for transvesicoscopic ureteral reimplantation using the Politano-Leadbetter technique (TVUR-PL). We describe the detailed surgical procedure and report operative outcomes.
We present a case of an intraperitoneal bladder injury during laparoscopic rectal surgery for pelvic organ prolapse. Lysis of adhesions was necessary to access the pelvis. We used an ultrasonic dissector and inadvertently caused damage to the bladder dome.
AIMS: Long-term indwelling catheterisation may affect health related quality of life, but clinical assessment and monitoring of people with indwelling catheters is poorly recorded because there are no validated measures to capture these criteria.
This article is a case study examining the diagnosis and management of bladder dysfunction and catheter-associated pain in an older woman with diabetes and a hypotonic bladder.
In a survey of acute care hospitals across the United States, we found that many hospitals use indwelling urinary catheters for reasons that are not medically necessary (eg, urinary incontinence without outlet obstruction and patient/family requests).
BACKGROUND: Caesarean section (CS) is the most common obstetric surgical procedure, with more than one-third of pregnant women having lower-segment CS.
BERKELEY, CA (UroToday.com) - We observed that the removal of urinary catheters within 24 hours of kidney transplantation did not increase the incidence of urine leaks as might be expected from such expeditious catheter removal.
BACKGROUND: Urinary tract infection (UTI) is the most common hospital-acquired infection.
Background: Although indwelling urethra catheterization is a medical intervention with well-defined risks, studies show that approximately 14-38% of the indwelling urethra catheters (IUCs) are placed without a specific medical indication. In this paper we describe the prevalence of IUCs, including their inappropriate use in the Netherlands. We also determine factors associated with inappropriate use of IUCs in hospitalized patients.
SinR is the master regulator that determines whether Bacillus subtilis switches from a free-living, planktonic lifestyle to form a biofilm, a community of cells attached to a surface by an extracellular matrix. Biofilms are an increasing environmental and healthcare issue, causing problems ranging from the bio-fouling of ocean-going vessels, to dental plaque, infections of the urinary tract and contamination of medical instruments such as catheters. SinR inhibits biofilm formation by repressing a number of extracellular matrix-associated operons. The activity of SinR is controlled by the SinR antagonists, SinI, SlrA and SlrR, which interact with SinR to regulate its function. We have combined isothermal titration calorimetry (ITC) and surface plasmon resonance (SPR) to determine the thermodynamic and kinetic parameters governing the protein:protein and protein:DNA interactions at the heart of this epigenetic switch. Finally, we present the crystal structure of the SinR tetramer in complex with DNA, revealing the molecular basis of base-specific DNA recognition by SinR and the mode by which SinR activity is controlled by interaction with its antagonists.

ABSTRACT
Clinical urine specimens are usually considered to be sterile when they do not yield uropathogens using standard clinical cultivation procedures. Our aim was to test if the adult female bladder might contain bacteria that are not identified by these routine procedures. An additional aim was to identify and recommend the appropriate urine collection method for the study of bacterial communities in the female bladder. Consenting participants who were free of known urinary tract infection provided urine samples by voided, transurethral, and/or suprapubic collection methods. The presence of bacteria in these samples was assessed by bacterial culture, light microscopy, and 16S rRNA gene sequencing. Bacteria that are not or cannot be routinely cultivated (hereinafter called uncultivated bacteria) were common in voided urine, urine collected by transurethral catheter (TUC), and urine collected by suprapubic aspirate (SPA), regardless of whether the subjects had urinary symptoms. Voided urine samples contained mixtures of urinary and genital tract bacteria. Communities identified in parallel urine samples collected by TUC and SPA were similar. Uncultivated bacteria are clearly present in the bladders of some women. It remains unclear if these bacteria are viable and/or if their presence is relevant to idiopathic urinary tract conditions.

BACKGROUND: The urinary system is the most common site for all hospital-acquired infections, accounting for approximately 40% of all nosocomial infections. The US Centers for Medicare & Medicaid Services has enacted 2 policies that have focused considerable attention on the optimal use of indwelling catheters in the acute and long-term care settings and the prevention of complications including catheter-associated urinary tract infection (CAUTI).
OBJECTIVES: This is the first of a 2-part Evidence-Based Report Card reviewing current evidence pertaining to nursing actions for prevention of CAUTIs in patients with short- and long-term indwelling catheters. Part 1 reviews evidence for materials for catheter construction, including incorporation of antimicrobial substances into the catheter, and selection of catheter size.
SEARCH STRATEGY: Nursing actions for prevention of CAUTIs were identified based on search of electronic databases and Web-based search engines for national or international clinical practice guidelines focusing on this topic. Evidence related to 2 common nursing interventions, selection of the material of construction and selection of catheter size, was identified by searching electronic databases MEDLINE, CINAHL, the Cochrane Library, and the ancestry of articles identified in these searches.
RESULTS: We found robust evidence supporting insertion of a silver alloy-coated catheter to reduce the risk of CAUTIs for up to 2 weeks in adult patients managed by short-term indwelling catheterization. We also found evidence supporting the insertion of an antibiotic-impregnated catheter for reduction of CAUTI risk for up to 7 days. There was insufficient evidence to determine whether regular use of an antimicrobial catheter reduces the risk of CAUTIs in adults managed with long-term indwelling catheterization. There was insufficient evidence to determine whether selection of a latex catheter, hydrogel-coated latex catheter, silicone-coated latex catheter, or all- silicone catheter influences CAUTI risk. Expert opinion suggests that selection of a smaller French-sized catheter reduces CAUTI risk, but evidence is lacking.
IMPLICATIONS FOR PRACTICE: Insertion of an antimicrobial catheter, either silver alloy or antimicrobial coated, is recommended for patients with short-term indwelling catheterization. There is insufficient evidence to recommend their use in patients managed by long-term indwelling catheterization. Selection of smaller French sizes for short- or long-term catheterization is thought to improve comfort and reduce CAUTI risk, but further research is needed to substantiate these best practice recommendations.
