“…In order to meet this challenge, an alternative indwelling catheter system must be developed. Taking into account the data presented in this review, as well as other analyses [ 82–84 ], the following research agenda can be proposed: The catheter should be easy to insert and withdraw. This means that the catheter should be flexible and experience minimal friction with the urethra, possibly by the application of durable, lubricious, antibacterial and hydrophilic coating [ 85 ].…”

For more than 3500 years, urinary catheters have been used to drain the bladder when it fails to empty. For people with impaired bladder function and for whom the method is feasible, clean intermittent self-catheterization is the optimal procedure. For those who require an indwelling catheter, whether short- or long-term, the self-retaining Foley catheter is invariably used, as it has been since its introduction nearly 80 years ago, despite the fact that this catheter can cause bacterial colonization, recurrent and chronic infections, bladder stones and septicaemia, damage to the kidneys, the bladder and the urethra, and contribute to the development of antibiotic resistance. In terms of medical, social and economic resources, the burden of urinary retention and incontinence, aggravated by the use of the Foley catheter, is huge. In the UK, the harm resulting from the use of the Foley catheter costs the National Health Service between £1.0–2.5 billion and accounts for ∼2100 deaths per year. Therefore, there is an urgent need for the development of an alternative indwelling catheter system. The research agenda is for the new catheter to be easy and safe to insert, either urethrally or suprapubically, to be retained reliably in the bladder and to be withdrawn easily and safely when necessary, to mimic natural physiology by filling at low pressure and emptying completely without damage to the bladder, and to have control mechanisms appropriate for all users.

“…The high incidence of urinary tract infection, mortality rates associated with the complication of urosepsis and costs to health services in managing the complications in patients undergoing long‐term catheterization are no longer acceptable in the 21st century . The management of bladder dysfunction is an important aspect of care for older and disabled people and, given the ageing population, the development of an effective system should have a high priority.…”

Clinical complications of urinary catheters caused by crystalline biofilms: something needs to be done

Abstract. Stickler DJ (Cardiff University, Cardiff, UK). Clinical complications of urinary catheters caused by crystalline biofilms: something needs to be done. (Review). J Intern Med 2014; 276: 120-129.This review is largely based on a previous paper published in the journal Spinal Cord. The care of many patients undergoing long-term bladder catheterization is complicated by encrustation and blockage of their Foley catheters. This problem stems from infection by urease-producing bacteria, particularly Proteus mirabilis. These organisms colonize the catheter forming an extensive biofilm; they also generate ammonia from urea, thus elevating the pH of urine. As the pH rises, crystals of calcium and magnesium phosphates precipitate in the urine and in the catheter biofilm. The continued development of this crystalline biofilm blocks the flow of urine through the catheter. Urine then either leaks along the outside of the catheter and the patient becomes incontinent or is retained causing painful distension of the bladder and reflux of urine to the kidneys. The process of crystal deposition can also initiate stone formation. Most patients suffering from recurrent catheter encrustation develop bladder stones. P. mirabilis establishes stable residence in these stones and is extremely difficult to eliminate from the catheterized urinary tract by antibiotic therapy. If blocked catheters are not identified and changed, serious symptomatic episodes of pyelonephritis, septicaemia and endotoxic shock can result. All types of Foley catheters including silver-or nitrofurazonecoated devices are vulnerable to this problem. In this review, the ways in which biofilm formation on Foley catheters is initiated by P. mirabilis will be described. The implications of understanding these mechanisms for the development of an encrustation-resistant catheter will be discussed. Finally, the way forward for the prevention and control of this problem will be considered.

“…Each year, around 100 million urethral catheters are sold worldwide, 25 millions of which are in the United States (Saint et al, 2000). Elastomers are commonly used materials for urethral catheters, such as latex rubber, silicone, polyvinyl chloride (PVC), and polyurethane (PU), given their excellent conformability and mechanical strength to form a robust channel for drainage (Dellimore et al, 2013). However, in general, the surface of elastomers has high lateral friction coefficient, causing the adhesion of urine components and external bacteria such as Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), which is a pivotal step in their colonization and further biofilm formation (Swartjes et al, 2014;An et al, 2017).…”

Robust Low Friction Antibiotic Coating of Urethral Catheters Using a Catechol-Functionalized Polymeric Hydrogel Film

et al. 2019

Indwelling urethral catheters are widely used in hospitalized patients. However, they are associated with bacterial infection and biofilm formation due to the suboptimal surface properties of the elastic materials used for the catheters. Although there are several antibacterial coating technologies to modify the surface properties of the catheter including hydrophilic polymeric coating, the risk of infection is still high given the absence of reactive functional groups on the surface of elastomers. In this study, we describe the use of catechol-functionalized hydrophilic polymers and explore strategies to create antibacterial hydrogel coatings. Three different types of catechol-functionalized polymers, chitosan, hyaluronic acid, and human serum albumin were synthesized and deposited using simple dip-coating method. All of the tested polymers could coat different types of elastomers widely used for urethral catheters independent of the surface properties while the thickness of the coating could be controlled by the number of depositions. The coating formed stable water-containing lubricant surface beneficial as a physical repellant of microbial attachment. In addition, the coating could be combined with additional antibacterial agents such as silver nanoparticles to maximize the antibacterial effect on the surface of urethral catheter materials.
