Abstract
BACKGROUND Neurogenic bladder dysfunction is a major problem for spinal cord injury (SCI) patients not only due to the risk of serious complications but also because of the impact on quality of life. The main aim of this study is to compare the rate of urinary tract infection (UTI) associated with hydrophilic-coated catheters versus uncoated polyvinyl chloride (PVC) catheters among SCI patients presenting with functional neurogenic bladder sphincter disorders. METHODOLOGY This was a retrospective cohort study from 2005 to 2020 including adult male or female patients who have an SCI at least more than 1 month ago with neurogenic bladder dysfunction and were using intermittent catheterization (single-use hydrophilic-coated or the standard-of-care polyvinyl chloride uncoated standard catheters) at least 3 times a day to maintain bladder emptying. RESULTS A total of 1000 patients were selected and recruited through a stratified random sampling technique with 467 (47.60%) patients in the uncoated catheter arm and 524 (52.60%) in the coated catheter groups. The three outcome measures, namely: symptomatic UTI, Bacteriuria, and pyuria were significantly higher in the group using uncoated polyvinyl chloride (PVC) catheters compared to hydrophilic-coated catheters at the rate of 79.60% vs.46.60%, 81.10% vs. 64.69, and 53.57% versus 41.79% respectively. Males, elder patients, longer duration, and severity of SCI were associated with increased risk of symptomatic UTI. CONCLUSIONS The results indicate a beneficial effect regarding clinical UTI when using hydrophilic-coated catheters in terms of fewer cases of symptomatic UTI. Bacteriuria is inevitable in patients with long-term catheterization, however, treatment should not be started unless the clinical symptoms exist. More attention should be given to the high-risk group for symptomatic UTIs.

Abstract
OBJECTIVE To explore the data comparing single- vs multi-use catheters for clean intermittent catheterisation (CIC), consider if the widespread use of single-use catheters is warranted given the cost and environmental impact, and put forth ideas for future consideration. METHODS A primary literature review was performed in PubMed over the past 50 years. Studies that performed comparative analysis of single- and multi-use catheters were included in our review. All studies that reported on primary data were narratively summarised. RESULTS A total of 11 studies were identified that reported on primary data comparing single- and multi-use catheters. There was no appreciable evidence suggesting reusable multi-use catheters were inferior to single-use catheters from an infection or usability standpoint. In addition, the environmental and monetary burden of single-use catheters is significant. CONCLUSIONS The intermittent catheter landscape in the USA has a complex past: defined by policy, shaped by industry, yet characterised by a paucity of data demonstrating superiority of single-use over multi-use catheters. We believe that the aversion to reusable catheters by many patients and healthcare professionals is unwarranted, especially given the cost and environmental impact. Moving forward, better comparative data and more sustainable practices are needed.

Abstract
When an individual has voiding difficulties, the person may require a urinary catheter. Enabling the person to choose an appropriate method of catheterisation and supporting them can have an enormous impact on the individual's health and wellbeing. Indwelling urethral catheters are suitable for some people but for others they can affect a person's lifestyle and lead to depression. Intermittent catheterisation can work well for some people. Intermittent self-catheterisation has been used to manage urinary retention for over 3500 years. It remains the 'gold standard' in terms of bladder drainage, but it is under-used and indwelling catheters remain more common. This article examines the history of intermittent catheterisation, indications for self-catheterisation and how to support people to use self-catheterisation.

Abstract
There is evidence that there is no difference in the incidence of urinary tract infections between multiple-use catheters that are cleaned after use and single-use catheters for intermittent catheterization. Despite the very significant economic and environmental advantages of multiple-use catheters, the single-use option is still promoted. The increasing focus on sustainability in urology may prompt a shift in practice to multiple-use catheters or other novel solutions in this setting. PATIENT SUMMARY: In intermittent catheterization, a patient or their caregiver periodically inserts a catheter to drain the bladder of urine. Single-use catheters are more expensive and have a greater impact on the environment than resuable catheters that are cleaned after use. To improve sustainability in health care, a switch from single-use to multiple-use catheters or other novel soultions for intermittent catheterization should be considered.

Abstract
We conducted a cross-sectional study using an online questionnaire to investigate the current status of urinary tract infections (UTIs) and the use of clean intermittent catheterization (CIC) in Chinese community-based SCI patients and to explore the risk factors for UTIs in patients using CIC. Our findings suggest that the prevalence of UTIS is higher in Chinese community-based SCI patients compared with patients in medically developed countries. In addition, we found that CIC had the lower incidence of UTIs than urinary indwelling catheter (UIC) and suprapubic catheter (SPC), and that SCI patients with CIC had low rates of use and poor compliance. Further analysis indicated that most of the risk factors for UTIs in CIC patients were associated with irregular use of CIC. Therefore, we call for not only the need to provide stronger caregiver support and financial assistance to improve CIC adherence in Chinese community SCI patients, but also the establishment of a database of Chinese SCI patients in order to enhance the management of bladder emptying methods and further standardize the CIC operation in such patients, thus reducing the risk of UTIs in Chinese community SCI patients.

Abstract
INTRODUCTION Clean intermittent catheterization (CIC) is associated with an increased risk of urinary tract infections (UTI), urethral trauma, urethral stenosis, hematuria, and pain. The first catheters were developed of polyvinyl carbon (PVC). Several types of catheters have been developed to reduce these complications, such as those with hydrophilic coating. OBJECTIVE To conduct a systematic review and meta-analysis to evaluate the effectiveness of hydrophilic coated catheters compared to uncoated catheters on the rate of UTI in patients using CIC. METHODOLOGY A systematic literature search was performed in OVID, Embase, Scopus, Web of Science, PubMed, and CENTRAL databases. Randomized controlled trials (RCTs) or randomized crossover trials comparing UTI and hematuria rates in patients using hydrophilic vs. non-hydrophilic catheters for CIC were identified. The selected trials were evaluated for risk of bias using the "Revised Cochrane risk-of-bias tool for randomized trials (RoB 2)." The results were expressed as a risk ratio (RR) with a 95% confidence interval (CI), under a random-effects model. Data were analyzed using Review Manager 5.4 software. RESULTS Nine studies with a total of 525 patients in CIC were analyzed. Overall, the use of hydrophilic catheters had a lower risk of UTIs compared to uncoated catheters (RR = 0.78; 95% CI 0.62-0.97; I2 = 37%). Five of the studies include patients > 18 years, showing a reduction of UTIs with the use of hydrophilic catheters (RR = 0.83; 95% CI 0.74-0.93; I2 = 0%). There was no difference in UTI development when comparing single-use uncoated vs hydrophilic catheters. However, heterogeneity was high (RR = 0.77; 95% CI 0.59-1.00; I2 = 57%). Regarding hematuria risk reduction, we were unable to identify differences between the use of hydrophilic catheters compared to uncoated catheters (RR = 1.02; 95% CI 0.66-1.60). CONCLUSION We found a risk reduction of UTIs associated with using hydrophilic catheters in adults, with low heterogeneity. Regarding hematuria, significant differences were not proved. We do not find a significant difference in UTI risk reduction in the pediatric population. Urethral trauma presence could not be meta-analyzed due to a lack of information reported.

A scoping review on the impact of hydrophilic versus non-hydrophilic intermittent catheters on UTI, QoL, satisfaction, preference, and other outcomes in neurogenic and non-neurogenic patients suffering from urinary retention. BMC Urol 2022; 22:153. [PMID: 36123663 PMCID: PMC9487088 DOI: 10.1186/s12894-022-01102-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Accepted: 09/05/2022] [Indexed: 11/13/2022] Open
Abstract
Background For patients suffering from urinary retention due to neurogenic [e.g., spinal cord injury (SCI), spina bifida (SB), multiple sclerosis (MS)] or non-neurogenic [e.g., cancer, benign prostate hypertrophy (BPH)] causes, intermittent catheterization is the primary choice for bladder emptying. This scoping review compared hydrophilic-coated intermittent catheters (HCICs) with non-hydrophilic (uncoated) catheters in neurogenic and non-neurogenic patients with respect to satisfaction, preference, adverse events, urinary tract infection (UTI), quality of life (QoL), cost effectiveness, pain, and discomfort. Methods A systematic literature search was conducted using PubMed, Cochrane Library, Google Scholar, Embase, and available clinical practice guidelines and was limited to systematic reviews/meta-analysis and clinical studies (randomized trials, cohort and case–control studies) published in English between 2000 and 2020. A narrative synthesis was performed, comparing HCIC with non-hydrophilic catheters in each pathology. The articles where critically appraised and weighted according to their level of evidence based on the Oxford Centre for Evidence-Based Medicine Levels of Evidence grading. Results Thirty seven original articles and 40 reviews were included. The comparison of HCICs versus non-hydrophilic catheters was well-documented in patients with mixed pathology, SCI, and to some extent SB. The available evidence predominantly indicates better outcomes with HCICs as reported by study authors, particularly, greater UTI reduction and improved satisfaction, cost-effectiveness, and QoL. However, SB studies in children did not report reduction in UTIs. Children complained about slippery catheters, indicating possible touching of the surface during insertion, which may compromise cleanliness of the procedure and affect outcomes such as UTI. Limited studies were available exclusively on BPH and none on MS; however, most studies performed on mixed pathologies, including BPH and MS, indicated strong preference for HCICs compared to non-hydrophilic catheters. Conclusions The findings generally support HCICs over non-hydrophilic catheters; however, most studies were fairly small, often used a mix of pathologies, and the conclusions were often based on studies with high drop-out rates that were therefore underpowered. Larger studies are needed to support the general finding that HCICs are the preferred choice in most populations. Additional training in children or redesigned catheters may be necessary for this age-group to fully benefit from the advantages of HCICs.

Abstract
Background Hydrophilic coated catheters are recommended to reduce the side effects of intermittent catheterization (IC) in patients with bladder dysfunction. However, there is lack of Level one evidence to support the use of this intervention. Search methods Several electronic databases were systematically searched to evaluate complication incidences for hydrophilic coated (HC) and non-hydrophilic catheters (NHC). Results Twelve studies were eligible for inclusion in the review. The meta-analyses exploring microscopic hematuria frequencies (RR = 0.69; 95% CI 0.52–0.90) and urethral stricture frequencies (RR = 0.28; 95% CI 0.13–0.60) showed a lower risk ratio associated with HC in comparison to NHC, whereas gross hematuria was no statistically significant difference in two groups. Subgroup analyses of gross hematuria which was grouped according to "catheterization frequency", "single/multiple catheterization" and "self/other catheterization” were performed and the values of combined RR were also no statistically significant difference. Conclusions Compared with non-hydrophilic catheters, the hydrophilic coated catheters have positive significance in reducing the incidence of urethral microtrauma and the urethral stricture. However, more studies are warranted for evaluating effects of hydrophilic coated catheters on the incidence of gross hematuria.

Abstract
BACKGROUND Intermittent catheterisation (IC) is a commonly recommended procedure for people with incomplete bladder emptying. Frequent complications are urinary tract infection (UTI), urethral trauma and discomfort during catheter use. Despite the many designs of intermittent catheter, including different lengths, materials and coatings, it is unclear which catheter techniques, strategies or designs affect the incidence of UTI and other complications, measures of satisfaction/quality of life and cost-effectiveness. This is an update of a Cochrane Review first published in 2007. OBJECTIVES: To assess the clinical and cost-effectiveness of different catheterisation techniques, strategies and catheter designs, and their impact, on UTI and other complications, and measures of satisfaction/quality of life among adults and children whose long-term bladder condition is managed by intermittent catheterisation. SEARCH METHODS We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, CINAHL, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 12 April 2021), the reference lists of relevant articles and conference proceedings, and we attempted to contact other investigators for unpublished data or for clarification. SELECTION CRITERIA Randomised controlled trials (RCTs) or randomised cross-over trials comparing at least two different catheterisation techniques, strategies or catheter designs. DATA COLLECTION AND ANALYSIS As per standard Cochrane methodological procedures, two review authors independently extracted data, assessed risk of bias and assessed the certainty of evidence using GRADE. Outcomes included the number of people with symptomatic urinary tract infections, complications such as urethral trauma/bleeding, comfort and ease of use of catheters, participant satisfaction and preference, quality of life measures and economic outcomes. MAIN RESULTS We included 23 trials (1339 randomised participants), including twelve RCTs and eleven cross-over trials. Most were small (fewer than 60 participants completed), although three trials had more than 100 participants. Length of follow-up ranged from one month to 12 months and there was considerable variation in definitions of UTI. Most of the data from cross-over trials were not presented in a useable form for this review. Risk of bias was unclear in many domains due to insufficient information in the trial reports and several trials were judged to have a high risk of performance bias due to lack of blinding and a high risk of attrition bias. The certainty of evidence was downgraded for risk of bias, and imprecision due to low numbers of participants. Aseptic versus clean technique We are uncertain if there is any difference between aseptic and clean techniques in the risk of symptomatic UTI because the evidence is low-certainty and the 95% confidence interval (CI) is consistent with possible benefit and possible harm (RR 1.20 95% CI 0.54 to 2.66; one study; 36 participants). We identified no data relating to the risk of adverse events comparing aseptic and clean techniques or participant satisfaction or preference. Single-use (sterile) catheter versus multiple-use (clean) We are uncertain if there is any difference between single-use and multiple-use catheters in terms of the risk of symptomatic UTI because the certainty of evidence is low and the 95% CI is consistent with possible benefit and possible harm (RR 0.98, 95% CI 0.55, 1.74; two studies; 97 participants). One study comparing single-use catheters to multiple-use catheters reported zero adverse events in either group; no other adverse event data were reported for this comparison. We identified no data for participant satisfaction or preference. Hydrophilic-coated catheters versus uncoated catheters We are uncertain if there is any difference between hydrophilic and uncoated catheters in terms of the number of people with symptomatic UTI because the certainty of evidence is low and the 95% CI is consistent with possible benefit and possible harm (RR 0.89, 95% CI 0.69 to 1.14; two studies; 98 participants). Uncoated catheters probably slightly reduce the risk of urethral trauma and bleeding compared to hydrophilic-coated catheters (RR 1.37, 95% CI 1.01 to 1.87; moderate-certainty evidence). The evidence is uncertain if hydrophilic-coated catheters compared with uncoated catheters has any effect on participant satisfaction measured on a 0-10 scale (MD 0.7 higher, 95% CI 0.19 to 1.21; very low-certainty evidence; one study; 114 participants). Due to the paucity of data, we could not assess the certainty of evidence relating to participant preference (one cross-over trial of 29 participants reported greater preference for a hydrophilic-coated catheter (19/29) compared to an uncoated catheter (10/29)). AUTHORS' CONCLUSIONS: Despite a total of 23 trials, the paucity of useable data and uncertainty of the evidence means that it remains unclear whether the incidence of UTI or other complications is affected by use of aseptic or clean technique, single (sterile) or multiple-use (clean) catheters, coated or uncoated catheters or different catheter lengths. The current research evidence is uncertain and design and reporting issues are significant. More well-designed trials are needed. Such trials should include analysis of cost-effectiveness because there are likely to be substantial differences associated with the use of different catheterisation techniques and strategies, and catheter designs.

Abstract
BACKGROUND This systematic review had 2 aims. First to identify the incidence of urinary tract infection (UTI) and bacteriuria in people undertaking intermittent catheterization (IC), second to determine the effectiveness of antiseptic cleaning of the meatal area prior to IC in reducing the incidence of UTI and bacteriuria. METHODS A systematic review was conducted. Medline and the Cumulative Index to Nursing and Allied Health Literature electronic databases were systematically searched between January 1, 1990 and January 31, 2020, to identify studies that reported either the incidence of UTI or bacteriuria or the impact of using antiseptics for meatal cleaning prior to IC on incidence of these same outcomes. RESULTS Twenty-five articles were identified for the first aim, 2 articles for the second. The proportion of participants experiencing ≥1 UTIs per year ranged from 15.4% to 86.6%. Synthesis of these studies suggest a combined incidence of 44.2% (95%CI 40.2%-48.5%) of participants having ≥1 UTIs per year. One of the 2 studies exploring the benefit of antiseptics in reducing UTI suggest some potential benefit of using chlorhexidine in reducing UTIs. Both studies have significant limitations, making interpretation difficult. CONCLUSIONS A large proportion of people undertaking IC in the community have UTIs each year. Evidence on the role of antiseptics in the prevention of UTI for people who undertake IC remains unclear.

Abstract
Introduction: Bladder and urinary sphincter malfunctioning that results from some change in the central and/or peripheral nervous system is defined as neurogenic bladder. The urinary tract symptoms that can be related to its filling, emptying, or both have a significant impact on the quality of life of individuals. The present review was based on the document prepared for the public health system in Brazil as a treatment guidelines proposal. Material and Methods: Survey questions were structured as per PICO (Population, Intervention, Control, and Outcome). Search strategies were defined and performed in the MEDLINE/Pubmed, Embase, Epistemonikos and Google Scholar databases. The selection of articles followed the evidence hierarchy concept; evidence body was identified, and the quantitative study data were extracted. The quality of evidence and grade of recommendation were qualitatively assessed according to GRADE (Grading of Recommendations, Assessment, Development and Evaluations). Results: A total of 2.707 articles were identified, with 49 of them being selected to compose the basis for this review. Neurogenic bladder treatments were classified according to their focus on filling or emptying symptoms and sub- classified in pharmacological and surgical treatments. Conclusion: Treatment guidelines are important tools for the public health system to promote the best practice when treating neurogenic bladder patients.

Catheters for intermittent catheterization: a systematic review and network meta-analysis. Spinal Cord 2021; 59:587-595. [PMID: 33911191 DOI: 10.1038/s41393-021-00620-w] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2020] [Revised: 02/13/2021] [Accepted: 02/25/2021] [Indexed: 02/05/2023]
Abstract
STUDY DESIGN Systematic review and network meta-analysis. OBJECTIVES Intermittent catheterization (IC) is considered the standard treatment for neuro-urological patients who are unable to empty their bladders. The present study aimed to conduct a systematic evaluation and network meta-analysis of all available types of intermittent catheters, and determine which one is best suited for clinical use. METHODS We searched MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) databases to identify relevant studies. Only randomized clinical trials (RCTs) were included. Five types of catheters were identified based on the included studies. A Bayesian network meta-analysis was then performed. The surface under the cumulative ranking (SUCRA) curve was used to determine the best catheter for each outcome. RESULTS A total of 25 RCTs, involving 1233 participants, were included. The pooled odds ratios of symptomatic UTI were lower for two ready-to-use single-use catheters (gel-lubricated non-coated catheter, OR: 0.30, 95% CI 0.095-0.86; pre-activated hydrophilic-coated catheter, OR: 0.41, 95% CI 0.19-0.83) as compared to single-use non-coated catheter. In terms of patient satisfaction, the SUCRA results showed that the pre-activated hydrophilic-coated catheter may the preferred option (SUCRA = 82.8%). However, there were no significant differences in all outcome measures between traditional single-use non-coated catheters and clean non-coated catheters. CONCLUSION Ready-to-use single-use catheters are associated with lower rates of UTI compared to traditional catheters. Patients may be most satisfied with the pre-activated one. For traditional single-use non-coated catheters and clean non-coated catheters, there is still no convincing evidence as to which is better. Thus, more well-designed trials are needed.

Abstract
Ureteral stents have been widely used as biomedical devices to treat some urological diseases for several decades. However, the encrustation complications hamper the long-time clinical use of the ureteral stents. In this work, a new type of biodegradable material for the ureteral stents, methoxypoly(ethylene glycol)-block-poly(L-lactide-ran-Ɛ-caprolactone) (mPEG-PLACL), is evaluated to overcome this problem. The results show that the hydrophilicity and degradation rate in artificial urine of mPEG-PLACL are both significantly increased. It is worth noting that the mPEG-PLACL shows a lower amount of encrustation after immersing the stents in the dynamic urinary extracorporeal circulation (DUEC) model for 7 days. In addition, 71% Ca and 92% Mg are inhibited in vivo by quantitative analysis. Pathological analysis exhibit that the mPEG-PLACL cause less diffuse mucosal hyperplasia after 7 weeks of implantation. All the results indicate that this new type of biodegradable material had an excellent potential for the ureteral stents in the future.

Abstract
INTRODUCTION Intermittent self-catheterisation has revolutionised the management of neurogenic bladder-sphincter dysfunctions. The Liquick Base catheter is characterised by a streamlined Ergothan tip. The purpose of this study is to assess the tolerance and perception of patients using this catheter. MATERIALS AND METHODS A French prospective multicentre observational study was conducted on patients with neurogenic bladder-sphincter dysfunctions. Upon inclusion in the study, the doctor completed a questionnaire on the patient's pathology. After 3 and 6 months, the doctor checked for neurogenic developments or observations and looked for any complications relating to intermittent self-catheterisation. The patient completed a questionnaire to assess his or her perception of using the catheter. RESULTS Out of 42 patients included in the study, two were excluded. Out of the 40 assessed patients (30 males, 10 females) with an average age of 50.1±14.9 years, there were no reported cases of false passage. Bleeding occurred at least once in 10 patients (25%) in the first three months and in three out of 20 patients (15%) between 3 and 6 months. Two (5%) patients sought medical attention in the first three months for complications related to the catheter and 4 patients sought medical attention (10%) between 3 and 6 months. After 3 months 90% of patients were still using the catheter and after 6 months 90% of patients were still using the catheter. CONCLUSION The Liquick Base catheter is well tolerated. Patient perception is positive for all parameters being examined, leading to the continued use of the catheter in 90% of cases. LEVEL OF EVIDENCE 2.

Abstract
Abstract
Background
Standard urine sampling and testing techniques do not mitigate against detection of colonization, resulting in false positive catheter-associated urinary tract infections (CAUTI). We aimed to evaluate whether a novel protocol for urine sampling and testing reduces rates of CAUTI.
Methods
A preintervention and postintervention study with a contemporaneous control group was conducted at 2 campuses (test and control) of the same academic medical center. The test campus implemented a protocol requiring urinary catheter removal prior to urine sampling from a new catheter or sterile straight catheterization, along with urine bacteria and pyuria screening prior to culture. Primary outcomes were test campus CAUTI rates, compared between each 9-month pre- and postintervention epoch. Secondary outcomes included the percent reductions in CAUTI rates, compared between the test campus and a propensity score–matched cohort at the control campus.
Results
A total of 7991 patients from the test campus were included in the primary analysis, and 4264 were included in the propensity score–matched secondary analysis. In the primary analysis, the number of CAUTI cases per 1000 patients was reduced by 77% (6.6 to 1.5), the number of CAUTI cases per 1000 catheter days was reduced by 63% (5.9 to 2.2), and the number of urinary catheter days per patient was reduced by 37% (1.1 to 0.69; all P values ≤ .001). In the propensity score–matched analysis, the number of CAUTI cases per 1000 patients was reduced by 82% at the test campus, versus 57% at the control campus; the number of CAUTI cases per 1000 catheter days declined by 68% versus 57%, respectively; and the number of urinary catheter days per patient decreased by 44% versus 1%, respectively (all P values < .001).
Conclusions
Protocolized urine sampling and testing aimed at minimizing contamination by colonization was associated with significantly reduced CAUTI infection rates and urinary catheter days.

Abstract
INTRODUCTION Our objective was to provide guidelines covering all aspects of intermittent catheterisation (intermittent self-catheterisation and third-party intermittent catheterisation). MATERIALS AND METHODS A systematic review of the literature based on Pubmed, Embase, Google scholar was initiated in December 2014 and updated in April 2019. Given the lack of robust data and the numerous unresolved controversial issues, guidelines were established based on the formal consensus of experts from steering, scoring and review panels. RESULTS This allowed the formulation of 78 guidelines, extending from guidelines on indications for intermittent catheterisation, modalities for training and implementation, choice of equipment, management of bacteriuria and urinary tract infections, to the implementation of intermittent catheterisation in paediatric, geriatric populations, benign prostatic hyperplasia patients and continent urinary diversion patients with a cutaneous reservoir as well as other complications. These guidelines are pertinent to both intermittent self-catheterisation and third-party intermittent catheterisation. CONCLUSION These are the first comprehensive guidelines specifically aimed at intermittent catheterisation and extend to all aspects of intermittent catheterisation. They assist in the clinical decision-making process, specifically in relation to indications and modalities of intermittent catheterisation options. These guidelines are intended for urologists, gynaecologists, geriatricians, paediatricians, neurologists, physical and rehabilitation physicians, general practitioners and other health professionals including nurses, carers….

Abstract
Poly(vinyl chloride) (PVC) biomaterials perform a host of life-saving and life-enhancing roles when employed as medical devices within the body. High frictional forces between the device surface and interfacing tissue can, however, lead to a host of complications including tissue damage, inflammation, pain, and infection. We herein describe a versatile surface modification method using multifunctional hydrogel formulations to increase lubricity and prevent common device-related complications. In a clinically relevant model of the urinary tract, simulating the mechanical and biological environments encountered in vivo, coated candidate catheter surfaces demonstrated significantly lower frictional resistance than uncoated PVC, with reductions in coefficient of friction values of more than 300-fold due to hydration of the surface-localized polymer network. Furthermore, this significant lubrication capacity was retained following hydration periods of up to 28 days in artificial urine at pH 6 and pH 9, representing the pH of physiologically normal and infected urine, respectively, and during 200 repeated cycles of applied frictional force. Importantly, the modified surfaces also displayed excellent antibacterial activity, which could be facilely tuned to achieve reductions of 99.8% in adherence of common hospital-acquired pathogens, Staphylococcus aureus and Proteus mirabilis, relative to their uncoated counterparts through incorporation of chlorhexidine in the coating matrix as a model antiseptic. The remarkable, and pH-independent, tribological performance of these lubricious, antibacterial, and highly durable surfaces offers exciting promise for use of this PVC functionalization approach in facilitating smooth and atraumatic insertion and removal of a wide range of medical implants, ultimately maintaining user health and dignity.

Abstract
Clean intermittent catheterization (CIC) is one of the core elements of neurogenic bladder management in the patients with spinal cord injury and is effective and safe to maintain low intra-bladder pressure and achieve urinary continence. Until now, the most notable development in urinary catheter products for CIC is the introduction of hydrophilic coating. Fortunately, in Korea, the national medical insurance has recently covered the cost for urinary catheters in this patient group. The purpose of this review is to summarize the history of CIC and the recent development of urinary catheter products. From our review, we would like to suggest a way of thinking that is the way forward for the future to improve the implementation of CIC with minimal morbidity.

Abstract
A risk factor model for urinary tract infections in patients with adult neurogenic lower urinary tract dysfunction performing clean intermittent catheterisation was developed; it consists of four domains, namely, (1) general (systemic) conditions in the patient, (2) individual urinary tract conditions in the patient, (3) routine aspects related to the patient, and (4) factors related to intermittent catheters per se. The conceptual model primarily concerns patients with spinal cord injury, spina bifida, multiple sclerosis, or cauda equina where intermittent catheterisation is a normal part of the bladder management. On basis of several literature searches and author consensus in case of lacking evidence, the model intends to provide an overview of the risk factors involved in urinary tract infections, with specific emphasis to describe those that in daily practice can be handled and modified by the clinician and so come to the benefit of the individual catheter user in terms of fewer urinary tract infections.

Abstract
INTRODUCTION Intermittent catheterization (IC) is one of the fundamental aspects of managing patients with chronic urinary retention. Although reuse of catheters has been allowed to be chosen as the first option for IC, the optimal method of IC and the type of catheter has been a long-standing debate. We conducted a literature review regarding risk of urinary tract infection (UTI) and the costs associated with different methods and catheters. METHODS A MEDLINE search via PubMed, EMBASE, and EBSCO host was conducted in March 2018. The date of publication was limited to 2014 to present/current. RESULTS Single use of catheters (hydrophilic-coated [HC] or uncoated [UC]) was considered to impose a lower risk of UTI in all studies, except in one study that included children, but did not test their dexterity to handle HC catheters. Cost-effectiveness of single-use catheters was confirmed by all studies during this period. CONCLUSIONS Reuse of catheters exposes the patient to a plethora of possible cleaning techniques and duration of catheter use. Patient adherence to cleaning method cannot be predicted and this further amplifies the risk of complications and their burden on the healthcare system. We recommend a patient-centred approach to consider HC catheters as the first option, while considering the patient's/caregiver's ability to accommodate the usage technique. Single-use UC catheters, and finally reuse of catheters are considered as next options if HC catheters are found difficult to handle (especially in children doing self-catheterization). Larger trials investigating this matter are required.

Abstract
AIMS This study investigated user perception and adherence related to a hydrophilic-coated urinary catheter (LoFric® Origo™), available for male patients who practice intermittent catheterization. DESIGN The study had a prospective observational design, including patients from 19 European hospitals. METHODS A total of 416 patients were eligible for the study; 179 experienced catheter users and 237 de novo. Two questionnaires were filled out, one describing background data and a second, 8 weeks later, evaluating catheter features. RESULTS The response rate for the second questionnaire was 88% (365 patients). Patients evaluating the new catheter showed a general satisfaction rate of 81% and 72% kept using it. The hygienic grip of the catheter was appreciated by 85% and the foldable feature by 67%. The results show that convenience, ease of use, and hygienic factors are patient-preferred features for a urinary catheter. These factors were confirmed for the evaluated hydrophilic-coated catheter.

Abstract
Catheter-associated urinary tract infections (CAUTIs) are one of the most common nosocomial infections and can lead to numerous medical complications from the mild catheter encrustation and bladder stones to the severe septicaemia, endotoxic shock, and pyelonephritis. Catheters are one of the most commonly used medical devices in the world and can be characterised as either indwelling (ID) or intermittent catheters (IC). The primary challenges in the use of IDs are biofilm formation and encrustation. ICs are increasingly seen as a solution to the complications caused by IDs as ICs pose no risk of biofilm formation due to their short time in the body and a lower risk of bladder stone formation. Research on IDs has focused on the use of antimicrobial and antibiofilm compounds, while research on ICs has focused on preventing bacteria entering the urinary tract or coming into contact with the catheter. There is an urgent need for in vitro urinary tract models to facilitate faster research and development for CAUTI prevention. There are currently three urinary tract models that test IDs; however, there is only a single very limited model for testing ICs. There is currently no standardised urinary tract model to test the efficacies of ICs.

Abstract
Normal functioning of articulating tissues is required for many physiological processes occurring across length scales from the molecular to whole organism. Lubricating biopolymers are present natively on tissue surfaces at various sites of biological articulation, including eyelid, mouth, and synovial joints. The range of operating conditions at these disparate interfaces yields a variety of tribological mechanisms through which compressive and shear forces are dissipated to protect tissues from material wear and fatigue. This review focuses on recent advances in active agents and biomaterials for therapeutic augmentation of friction, lubrication, and wear in disease and injured states. Various small-molecule, biological, and gene delivery therapies are described, as are tribosupplementation with naturally-occurring and synthetic biolubricants and polymer reinforcements. While reintroduction of a diseased tissue's native lubricant received significant attention in the past, recent discoveries and pre-clinical research are capitalizing on concurrent advances in the molecular sciences and bioengineering fields, with an understanding of the underlying tissue structure and physiology, to afford a desired, and potentially patient-specific, tissue mechanical response for restoration of normal function. Small and large molecule drugs targeting recently elucidated pathways as well as synthetic and hybrid natural/synthetic biomaterials for restoring a desired tissue mechanical response are being investigated for treatment of, for example, keratoconjunctivitis sicca, xeroderma, and osteoarthritis.

Abstract
STUDY DESIGN A Markov model was used to analyze cost-effectiveness over a lifetime horizon. OBJECTIVE To investigate the cost-effectiveness of hydrophilic-coated intermittent catheters (HCICs) compared with uncoated catheters (UCs) among individuals with neurogenic bladder dysfunction (NB) due to spinal cord injury (SCI). SETTING A Canadian public payer perspective based on data from Ontario; including a scenario analysis from the societal perspective. METHODS A previously published Markov decision model was modified to compare the lifetime costs and quality-adjusted life years (QALYs) for the two interventions. Three renal function and three urinary tract infection (UTI) health states as well as other catheter-related events were included. Scenario analyses, including utility gain from compact catheter and phthalate free catheter use, were performed. Deterministic and probabilistic sensitivity analyses were conducted to evaluate the robustness of the model. RESULTS The model predicted that a 50-year-old patient with SCI would gain an additional 0.72 QALYs if HCICs were used instead of UCs at an incremental cost of $48,016, leading to an incremental cost-effectiveness ratio (ICER) of $66,634/QALY. Moreover, using HCICs could reduce the lifetime number of UTI events by 11%. From the societal perspective, HCICs cost less than UCs, while providing superior outcomes in terms of QALYs, life years gained (LYG), and UTIs. The cost per QALY further decreased when health-related quality-of-life (HRQoL) gains associated with compact HCICs or catheters not containing phthalates were included. CONCLUSION In general, ICERs in the range of CAD$50-100,000 could be considered cost-effective. The ICERs for the base case and sensitivity analyses suggest that HCICs could be cost-effective. From the societal perspective, HCICs were associated with potential cost savings in our model. The results suggest that reimbursement of HCICs should be considered in these settings.

Abstract
Urinary tract infection (UTI) is a source of morbidity and healthcare costs in adults with spina bifida (ASB). UTI prevention strategies are often recommended, but the evidence of various approaches remains unclear. We performed a systematic review to inform a best practice policy statement for UTI prevention in ASB. On behalf of the Neurogenic Bladder Research Group (NBRG.org), we developed an a priori protocol and searched the published English literature for 30 outcomes questions addressing UTI prevention in ASB. The questions spanned the categories of antibiotics, oral supplements, bladder management factors and social support. Where there was little literature in ASB, we included literature from similar populations with neurogenic bladder (NB). Data was abstracted and then reviewed with recommendations made by consensus of all authors. Level of Evidence (LoE) and Grade of Recommendation (GoR) were according to the Oxford grading system. Of 6,433 articles identified by our search, we included 99 publications. There was sufficient evidence to support use of the following: saline bladder irrigation (LoE 1, GoR B), gentamicin bladder instillation (LoE 3, GoR C), single-use intermittent catheterization (IC) (LoE 2, GoR B), hydrophilic catheters for IC (LoE 2, GoR C), intradetrusor onabotulinumtoxinA injection (LoE 3, GoR C), hyaluronic acid (HA) instillation (LoE 1, GoR B), and care coordination (LoE 3, GoR C). There was sufficient evidence to recommend against use of the following: sterile IC (LoE 1, GoR B), oral antibiotic prophylaxis (LoE 2, GoR B), treatment of asymptomatic bacteriuria (LoE 2, GoR B), cranberry (LoE 2, GoR B), methenamine salts (LoE 1, GoR B), and ascorbic acid (LoE1, GoR B). There was insufficient evidence to make a recommendation for other outcomes. Overall, there are few studies in UTI prevention in the specific population of ASB. Research in populations similar to ASB helps to guide recommendations for UTI prevention in the challenging patient group of ASB. Future studies in UTI prevention specific to ASB are needed and should focus on areas shown to be of benefit in similar populations.

Abstract
INTRODUCTION Detrusor sphincter dyssynergia affects 70% to 80% of all spinal cord injury patients, resulting in increased risk of urinary tract infections (UTIs) and potential exposure to antimicrobial resistance. In Brazil, local guidelines recommend intermittent catheterization as the best method for bladder emptying, and two catheter types are available: the conventional uncoated PVC and the hydrophilic coated catheters. OBJECTIVE To evaluate the cost-effectiveness of two types of catheters for intermittent catheterization from the perspective of the Brazilian public healthcare system. MATERIALS AND METHODS A Markov model was used to evaluate cost-effectiveness in those with spinal cord injuries. A primary analysis was conducted on all possible adverse events, and a secondary analysis was performed with urinary tract infections as the only relevant parameter. The results were presented as cost per life years gained (LYG), per quality-adjusted life years (QALY) and per number of urinary tract infections (UTIs) avoided. RESULTS The base scenario of all adverse events shows a cost-effective result of hydrophilic coated catheters compared to uncoated PVC catheters at 57,432 BRL (Brazilian Reais) per LYG and 122,330 BRL per QALY. The secondary scenario showed that the use of hydrophilic coated catheters reduces the total number of UTIs, indicating that an additional cost of hydrophilic coated catheters of 31,240 BRL over a lifetime will reduce lifetime UTIs by 6%. CONCLUSIONS Despite the higher unit value, the use of hydrophilic coated catheters is a cost-effective treatment from the perspective of the Brazilian public healthcare system.

Abstract
BACKGROUND Intermittent catheterisation is a commonly recommended procedure for people with incomplete bladder emptying. There are now several designs of intermittent catheter (e.g. different lengths, 'ready to use' presentation) with different materials (e.g. PVC-free) and coatings (e.g. hydrophilic). The most frequent complication of intermittent catheterisation is urinary tract infection (UTI), but satisfaction, preference and ease of use are also important to users. It is unclear which catheter designs, techniques or strategies affect the incidence of UTI, which are preferable to users and which are most cost effective. OBJECTIVES To compare one type of catheter design versus another, one type of catheter material versus another, aseptic catheterisation technique versus clean technique, single-use (sterile) catheters versus multiple-use (clean) catheters, self-catheterisation versus catheterisation by others and any other strategies designed to reduce UTI and other complications or improve user-reported outcomes (user satisfaction, preference, ease of use) and cost effectiveness in adults and children using intermittent catheterisation for incomplete bladder emptying. SEARCH METHODS We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, and handsearching of journals and conference proceedings (searched 30 September 2013), the reference lists of relevant articles and conference proceedings, and we attempted to contact other investigators for unpublished data or for clarification. SELECTION CRITERIA Randomised controlled trials (RCTs) or randomised cross-over trials comparing at least two different catheter designs, catheterisation techniques or strategies. DATA COLLECTION AND ANALYSIS Two review authors assessed the methodological quality of trials and abstracted data. For dichotomous variables, risk ratios and 95% confidence intervals were derived for each outcome where possible. For continuous variables, mean differences and 95% confidence intervals were calculated for each outcome. Because of trial heterogeneity, it was not always possible to combine data to give an overall estimate of treatment effect. MAIN RESULTS Thirty-one trials met the inclusion criteria, including 13 RCTs and 18 cross-over trials. Most were small (less than 60 participants completed), although five trials had more than 100 participants. There was considerable variation in length of follow-up and definitions of UTI. Participant dropout was a problem for several trials, particularly where there was long-term follow-up to measure incidence of UTI. Fifteen trials were more than 10 years old and focused mainly on comparing different catheterisation techniques (e.g. single versus multiple-use) on clinical outcomes whereas, several more recent trials have focused on comparing different types of catheter designs or materials, especially coatings, and user preference. It was not possible to combine data from some trials owing to variations in the catheters tested and in particular the catheter coatings. Where there were data, confidence intervals around estimates were wide and hence clinically important differences in UTI and other outcomes could neither be identified nor reliably ruled out. No study assessed cost-effectiveness. AUTHORS' CONCLUSIONS Despite a total of 31 trials, there is still no convincing evidence that the incidence of UTI is affected by use of aseptic or clean technique, coated or uncoated catheters, single (sterile) or multiple-use (clean) catheters, self-catheterisation or catheterisation by others, or by any other strategy. Results from user-reported outcomes varied. The current research evidence is weak and design issues are significant. More well-designed trials are strongly recommended. Such trials should include analysis of cost-effectiveness because there are likely to be substantial differences associated with the use of different catheter designs, catheterisation techniques and strategies.

Abstract
BACKGROUND Clean intermittent catheterization (CIC) is frequently prescribed for bladder dysfunction, either per urethra or via a continent catheterizable channel. Small catheters may be required for infants or continent channels. Success with CIC is highly dependent upon patient and family compliance. The urinary flow rate through the catheter is an important factor, which can decrease CIC time and improve quality of life. There is little objective information regarding flow rate through urinary catheters to guide catheter recommendation or prescription. Clinically, we noted that there was a difference in flow among catheter brands, and we questioned if catheters of the same-labeled diameter exhibit the same flow characteristics, which could have implications for catheter selection. METHODS Twenty-one commercially available male pediatric urinary catheters from nine brands were tested (11 straight tip, 10 coude tip). Nine of the 21 tested catheters had a hydrophilic coating. All tested catheters shared a 10F outer diameter. For each, microscopic imaging and a precision caliper were used to measure the inner diameter and tip inlet area. A hydraulic system modified from ASTM standard testing specifications was used to simulate bladder catheterization. Measurement of each catheter was repeated five times using three different static hydraulic pressures (20, 40 and 50 cmH2O). Catheter flow rate and structural measurements were identified and the fastest and slowest of the catheters are presented in the table. The variable flow rates between brands were due to the differences in catheter structural characteristics such as the inner diameter (ID) and the tip inlet area to inner lumen area ratio (AR). The maximum variation of flow rate of all tested 10F catheters was 48%, ID varied up to 22%, from 1.71 to 2.11 mm or 5.13-6.33F. AR varied up to 166%. The table delineates the fastest and slowest rates at three measured pressures. The outer diameter labeled 10F on packaging was true to size. CONCLUSIONS Based on packaging information, providers, and patients are unable to predict urinary flow through a catheter and thus use information regarding flow rate to guide catheter selection. This information cannot be calculated based on ideal flow calculations and could be listed on packaging to assist physicians and families in selecting the optimal urinary catheter for CIC.

Abstract
STUDY DESIGN Systematic review (Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA); http://www.prisma-statement.org). OBJECTIVES Different types of catheters and techniques have been described in the past three decades to identify the best self-intermittent catheterization method. Our aim is to review systematically the literature on the most appropriate material and technique to perform self-intermittent catheterization in the adult neurogenic population. METHODS A systematic review search was performed through PubMed/Medline, Embase and Cochrane Central Register of Controlled Trials (CENTRAL) databases to study all types of self-intermittent catheters, and analyzing their impact on urinary tract infections (UTIs), urethral trauma, cost-effectiveness, quality of life and patient's satisfaction. We used the following keywords: 'intermittent catheterization/catheterisation', 'neurogenic', 'urinary catheters for intermittent use' and 'urethral catheterization/catheterisation' published by November 2015. RESULTS After screening 3768 articles, 31 were included in the final synthesis (level of evidence 1b to 2b). The 2188 trial participants were mainly spinal cord injury adults and women with multiple sclerosis. Hydrophilic-coated catheters tended to decrease the incidence of UTI as well as urethral trauma and improve patient's satisfaction when compared with non-hydrophilic-coated catheters. Similarly, prelubricated catheters were associated with better results in terms of patient satisfaction. Sterile technique seemed to decrease the incidence of recurrent UTI; however, these results are counter-balanced by significantly increasing cost compared with clean catheterization. CONCLUSIONS The present review demonstrated advantages of hydrophilic-coated catheters in decreasing risk of UTI and urethral trauma as well as improving patient's satisfaction. Prelubricated catheters has been shown to be superior to conventional polyvinyl chloride catheters. Randomized controlled trials comparing hydrophilic and prelubricated catheters must be conducted to assess possible superiority and cost-effectiveness.

Abstract
Background Intermittent catheterisation is the method of choice for the management of bladder dysfunctions. Different urinary catheters are available, but there is conflicting evidence on which type of catheter is best. The present study provides an objective evaluation of the clinical effectiveness of different subsets of urinary catheters. Methods A systematic literature review was performed for published RCTs regarding hydrophilic coated and PVC (standard) catheters for intermittent catheterisation. Separate meta-analyses were conducted to combine data on frequencies of urinary tract infections (UTIs) and haematuria. Two separate analyses were performed, including or excluding reused standard catheters. Results Seven studies were eligible for inclusion in the review. The meta-analyses exploring UTI frequencies showed a lower risk ratio associated with hydrophilic catheters in comparison to standard ones (RR = 0.84; 95% CI, 0.75–0.94; p = 0.003). Results for the “reuse” scenario were consistent with the ones related to “single-use” scenario in terms of frequency of UTIs. The meta-analyses exploring haematuria were not able to demonstrate any statistically significant difference between hydrophilic catheters in comparison to standard ones. Conclusions The findings confirm previously reported benefits of hydrophilic catheters but a broader evaluation that takes into account also patient preferences, compliance of therapy, quality of life and costs would be needed to assess the economic sustainability of these advanced devices.

Abstract
Intermittent self-catheterisation (ISC) is the insertion and removal of a catheter to drain the bladder and is a safe and effective way to preserve renal function. It can be used as a one-off intervention to drain urine post-operatively or to measure residual urine volumes if a bladder scanner is unavailable. ISC can also be used as a long-term option to manage bladder dysfunction, and for some provides an excellent option to maintain independence and improve quality of life. Urinary tract infections are a common complication for women undertaking ISC. This article explores the prevention of urinary tract infections in women undertaking long-term ISC for the management of bladder dysfunction.

Abstract
BACKGROUND Intermittent catheterisation is a commonly recommended procedure for people with incomplete bladder emptying. There are now several designs of intermittent catheter (e.g. different lengths, 'ready to use' presentation) with different materials (e.g. PVC-free) and coatings (e.g. hydrophilic). The most frequent complication of intermittent catheterisation is urinary tract infection (UTI), but satisfaction, preference and ease of use are also important to users. It is unclear which catheter designs, techniques or strategies affect the incidence of UTI, which are preferable to users and which are most cost effective. OBJECTIVES To compare one type of catheter design versus another, one type of catheter material versus another, aseptic catheterisation technique versus clean technique, single-use (sterile) catheters versus multiple-use (clean) catheters, self-catheterisation versus catheterisation by others and any other strategies designed to reduce UTI and other complications or improve user-reported outcomes (user satisfaction, preference, ease of use) and cost effectiveness in adults and children using intermittent catheterisation for incomplete bladder emptying. SEARCH METHODS We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, and handsearching of journals and conference proceedings (searched 30 September 2013), the reference lists of relevant articles and conference proceedings, and we attempted to contact other investigators for unpublished data or for clarification. SELECTION CRITERIA Randomised controlled trials (RCTs) or randomised cross-over trials comparing at least two different catheter designs, catheterisation techniques or strategies. DATA COLLECTION AND ANALYSIS Two review authors assessed the methodological quality of trials and abstracted data. For dichotomous variables, risk ratios and 95% confidence intervals were derived for each outcome where possible. For continuous variables, mean differences and 95% confidence intervals were calculated for each outcome. Because of trial heterogeneity, it was not always possible to combine data to give an overall estimate of treatment effect. MAIN RESULTS Thirty-one trials met the inclusion criteria, including 13 RCTs and 18 cross-over trials. Most were small (less than 60 participants completed), although five trials had more than 100 participants. There was considerable variation in length of follow-up and definitions of UTI. Participant dropout was a problem for several trials, particularly where there was long-term follow-up to measure incidence of UTI. Fifteen trials were more than 10 years old and focused mainly on comparing different catheterisation techniques (e.g. single versus multiple-use) on clinical outcomes whereas, several more recent trials have focused on comparing different types of catheter designs or materials, especially coatings, and user preference. It was not possible to combine data from some trials owing to variations in the catheters tested and in particular the catheter coatings. Where there were data, confidence intervals around estimates were wide and hence clinically important differences in UTI and other outcomes could neither be identified nor reliably ruled out. No study assessed cost-effectiveness. AUTHORS' CONCLUSIONS Despite a total of 31 trials, there is still no convincing evidence that the incidence of UTI is affected by use of aseptic or clean technique, coated or uncoated catheters, single (sterile) or multiple-use (clean) catheters, self-catheterisation or catheterisation by others, or by any other strategy. Results from user-reported outcomes varied. The current research evidence is weak and design issues are significant. More well-designed trials are strongly recommended. Such trials should include analysis of cost-effectiveness because there are likely to be substantial differences associated with the use of different catheter designs, catheterisation techniques and strategies.

Abstract
OBJECTIVE to seek the best evidence available in the literature concerning the knowledge produced and related to the techniques of intermittent and indwelling urinary catheterization, so as to place the nursing care given to patients submitted to urinary catheterization on a scientific foundation and to prevent urinary tract infections. METHOD the literature search was undertaken in the Pubmed and Cochrane databases for the development of the integrative review. The sample was of 34 articles. These were analyzed by two independent researchers using an instrument adapted for ascertaining the level of evidence and the grade of recommendation, in addition to the use of the Jadad scale. RESULTS the evidence available related to the nursing care for patients submitted to urinary catheterization is: the infection rate in the urinary tract does not alter whether the perineum is cleaned with sterile water or not, or with the use of povidone-iodine solution or chlorhexidine; or using clean or sterile technique. The use of an intermittent catheter with clean technique results in low rates of complications or infections compared to the use of an indwelling catheter. The removal of the catheter in up to 24 hours after surgery and the use of an antimicrobial-impregnated or hydrophilic-coated catheter reduce urinary tract infection . CONCLUSIONS there are controversies in relation to periurethral cleansing technique, the type of material the catheter is made of, and some procedures for the maintenance and removal of the catheter. This review's results represent an updating of the nurse's conducts and decision-making for the prevention of urinary tract infections in urinary catheterization.
