“…While majority studies defined bacteriuria as �10 5 Colony-forming units (CFU)/ml, one study considered bacteriuria as �100 CFU/ml [27]. Combined clinical and microbiological criteria to define symptomatic CAUTI were used only in four studies [10,11,13,15], which too were variable.…”

“…Three employed silver-oxide catheters [19,21,22], two studies were only in abstract form [20,23], two studied the effects of long-term catheterization [25,26] while one study compared two different types of silver-coated catheters [24]. A total of 13 studies were included in the review [10][11][12][13][14][15][27][28][29][30][31][32][33]. Details of the included studies are presented in Table 1.…”

“…One paper had two sub-reports in the same article which were analyzed separately [30]. Except for one prospective cross-over trial [15], all were RCTs. There was a large variation in the sample size in the studies included in the meta-analysis, varying from 11 to 2144 participants per group.…”

“…In a Cochrane review by Lam et al, the authors had evaluated evidence on the efficacy of such noble-metal coated catheters in 2014 [8]. Since then many new trials have been published and there is a need for updated evidence on this subject, to provide guidelines to health-care providers [12][13][14][15]. Hence, the primary objective of this review was to perform a systematic literature search and conduct a meta-analysis to answer the clinical question: Does the use of noble-metal coated urinary catheters for short-term catheterization of adults reduce the incidence of CAUTI?…”

Objective To evaluate the efficacy of noble-metal coated catheters in reducing catheter-associated urinary tract infections (CAUTI) in adult patients requiring short term catheterization. Methods An electronic literature search of PubMed, BioMed Central, Embase, Scopus, CENTRAL (Cochrane Central Register of Controlled Trials) and Google scholar was carried out from inception to 10th October 2019. Any prospective study or randomized controlled trial (RCT) on adult patients comparing noble-metal coated urinary catheters with any standard catheter and evaluating the incidence of CAUTI or bacteriuria was included. Results A total of 13 studies were included in the systematic review. 12 were RCTs and one was a prospective cross-over trial. Catheters employed in the study group were grouped into two subgroups: Silver alloy coated or Noble metal alloy-coated (Gold, Silver, and Palladium) catheters. Bacteriuria was the most commonly studied outcome variable across trials. Metaanalysis indicated that silver alloy-coated catheters (RR 0.63, 95%CI 0.44-0.90, P = 0.01; I2 = 72%) and noble metal alloy catheters (RR 0.58, 95%CI 0.41-0.81, P = 0.001; I2 = 0%) significantly reduce the risk of bacteriuria. Subgroup analysis based on the duration of catheterization demonstrated that silver alloy catheters reduce the risk of bacteriuria with >1week of catheterization (RR 0.46, 95%CI 0.26-0.81, P = 0.007; I2 = 63%). Symptomatic CAUTI was evaluated only in four studies with variable results. The quality of the included studies was not high. Conclusions Our review indicates that bacteriuria may be reduced with the use of noble metal-coated catheters during short-term catheterization of adults, however, the quality of evidence is not

“…Desai et al demonstrated the ineffectiveness of silver impregnated catheters to prevent CAUTI . More recently, a nonrandomized crossover study showed even no advantages of the silver‐coated silicone catheter (BIP™ silicone catheter) in reduction of the incidence of CAUTI, including cystitis, febrile UTI, and urosepsis, in this cohort of critically ill patients . In general, silver‐coated catheters are effective against CAUTI; however, the effectiveness is limited in certain uropathegon‐catheter models, as well as the severity of medical condition of the patients in the clinical studies.…”

Over 75% of hospital‐acquired or nosocomial urinary tract infections are initiated by urinary catheters, which are used during the treatment of 16% of hospitalized patients. Taking the United States as an example, the costs of catheter‐associated urinary tract infections (CAUTI) are in excess of $451 million dollars/year. The biofilm formation by pathogenic microbes that protects pathogens from host immune defense and antimicrobial agents is the leading cause for CAUTI. Thus, tremendous efforts have been devoted to antimicrobial coating for urinary catheters in the past few decades, and it has been demonstrated to be one of the most direct and efficient strategies to reduce infections. In this article, we briefly summarize the current methods for preparation of antimicrobial coatings based on different stages in the biofilm formation, highlight recent progress in the urinary catheter coating material design and selection, discuss approaches to improving their long‐term antimicrobial efficacy, biocompatibility, multidrug resistance and recurrent infections, and finally outline future requirements and prospects in antimicrobial coating material design. The scope of the works surveyed is confined to antimicrobial urinary catheters. © 2018 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 107A: 445–467, 2019.

Ureteral stents are broadly used for the treatment of a wide range of pathologies, with different complexities and characteristics. Despite being efficient, the morbidity associated with stents, such as bacterial infection and pain, limits their therapeutic action and often represents an increase in healthcare costs. As no single solution fits all problems, there is still a need to improve these medical devices. Throughout this review, the most recent innovations are outlined and suggestions regarding future directions for ureteral stent technology are formulated with respect to materials, coatings, and designs of these devices. As highlighted here, during the process of passing these innovations to the growing market of ureteral stents, one of the biggest challenges is to increase the predictive value of the in vitro assays and, consequently, reduce the number of in vivo tests needed. Thus, recommendations concerning in vitro standard testing of these devices are provided, with focus on medium, flow conditions, and microbiological parameters. Additionally, the reader is also presented with insights about a crucial but rarely discussed topic, the bureaucratic part of the bench to market process, particularly the product certification legislation in Europe.

Catheter-associated urinary tract infections and other infections in patients hospitalized for acute stroke: A prospective cohort study of two different silicone catheters

Abstract: CAUTIs were the most frequent healthcare-associated infections, slightly ahead of pulmonary tract infections. No advantages of the coated catheter could be found in this cohort of critically ill patients.
