Market demand growth and technological innovation for urinary catheters

Urinary catheterization is one of the most basic procedures in clinical nursing, playing a vital role in clinical medicine and nursing. The urinary catheter is the core product used in catheterization to help patients drain urine. Globally, the European and American markets, with their more developed healthcare industries, have a greater demand for urinary catheters, and this demand continues to increase annually. In other regions, the demand for urinary catheters is also constantly increasing due to the aging population. With advancements in catheter manufacturing processes, the urinary catheter industry has enormous future development potential.

According to market research and consulting firms, the global urinary catheter market is projected to grow at a CAGR of nearly 5% from 2020 to 2030; the global urinary catheter market is expected to be valued at over US$2.2 billion by the end of 2030, with silicone catheters and latex catheters holding the largest market share.

Urinary catheters have a wide range of applications worldwide. The United States, with its relatively high prevalence of urinary tract infections, is the world's largest market for catheters. Europe has become the second largest market globally, driven by soaring urinary tract disease incidence and government support for developing new medical assistive devices. The Asia-Pacific region, with its increasing number of urinary tract disease patients, will also hold a significant share of the catheter market. Factors such as the high prevalence of hospital-acquired infections, increased health awareness among healthcare professionals and patients, and increased investment in healthcare are expected to significantly boost the catheter market in economies like India and Japan.With the aging population and increasing demand for hygiene and health services, the market demand for urinary catheters is constantly rising. Research data shows that 25% to 35% of hospitalized patients require indwelling urinary catheters. The higher probability of urinary system-related diseases among the elderly will inevitably drive the growth in demand for related medical consumables. As a basic medical device product, urinary catheters have enormous market potential.

With the continuous development of production technology, urinary catheters have undergone a transformation from traditional to modern to fully automated production processes. Taking latex urinary catheters as an example, the traditional production process is mainly manual and involves many steps such as raw material use, impregnation molding, demolding, filtration, vulcanization, silicone coating treatment, appearance inspection, tube cutting, valve plugging, lining, inspection, packaging, sterilization, and finished product warehousing.Compared to traditional production processes, modern production processes utilize multi-functional automated equipment that integrates tube cutting, valve plugging, diaphragm installation, inflation, leak detection, blockage detection, air collection, and packaging in the assembly and inspection stages. This effectively increases enterprise capacity and improves product quality. Today, an increasing number of automated and precision equipment are being applied to the production of urinary catheters. Many companies have established automated production bases for latex urinary catheters, employing robots and automatic demolding machines to achieve fully automated production, reduce production costs, improve technological levels, further enhance product quality, and accelerate industry development.

In clinical applications, besides shortening catheter indwelling time, ensuring adequate lubrication during insertion, and selecting appropriate tubing diameter, material modification is also an effective method to reduce the incidence of adverse events related to urinary catheters. Currently, the four most common catheter materials on the market are latex, silicone, polyvinyl chloride (PVC), and polyurethane (PU). Furthermore, novel materials such as hydrophilic coatings, antibacterial coatings, and super-lubricating antibacterial coatings have become research hotspots, and some of these new materials have already been widely applied in catheter production.

Polyvinylpyrrolidone (PVP), a hydrophilic coating material, is a hydrophilic synthetic polymer compound that can absorb water and form a thin water film on the surface of catheter latex material, thereby improving the lubricity and smoothness of the catheter surface. Researchers have used pharmaceutical-grade PVP to prepare hydrophilic lubricating coatings and conducted material performance tests. The results showed that this hydrophilic coating effectively improved the lubricity of the catheter surface, and the coating was not easily detached, exhibiting good lubrication durability. In recent years, the preparation process of hydrophilic coatings has been improved from traditional thermosetting to photocuring, resulting in higher adhesion and more durable lubrication on the catheter surface.

In clinical practice, antimicrobial-coated urinary catheters are mainly used to prevent catheter-associated urinary tract infections (CADIs). They are primarily classified into three types: chloramphenicol-coated catheters, aminoglycoside-coated catheters, and quinolone-coated catheters. Antimicrobial-coated catheters can effectively reduce the incidence of CATIs and are effective for patients with short-term indwelling catheters. However, multicenter clinical studies on their efficacy in patients with long-term indwelling catheters are currently lacking.

Super-slippery antibacterial coatings come in various types, with coatings containing silver components (such as silver ions and silver nanoparticles) being the most widely used. Silver-coated urinary catheters are approved for marketing globally, but their clinical safety and efficacy are still under further research and monitoring. In addition, gold-silver-palladium alloy coatings are a special type of super-slippery antibacterial coating that effectively prevents bacterial adhesion and colonization by releasing microcurrents; clinical evidence-based studies have demonstrated their safety and efficacy.
