Hydrophilic Urology Guidewire

This device is a high-performance hydrophilic guidewire specifically engineered for urological procedures. It is designed to assist in the placement and guidance of various instruments into natural body orifices or wound sites. It is commonly used in conjunction with J-tip catheters and disposable minimally invasive dilation and drainage sets, where it provides essential support and trajectory guidance. The guidewire features a Daxan hydrophilic coating, which rapidly absorbs and retains moisture to form an exceptionally lubricious surface. This significantly reduces friction during advancement and manipulation, thereby minimizing tissue irritation, trauma, and patient discomfort during both insertion and withdrawal. The product is available with either a straight or an angled tip and is sterilized using ethylene oxide (EO) for immediate and safe use.

Specifications

Length	120 cm / 150 cm / 180 cm
Diameter	0.032" / 0.035" / 0.038"

Key Features

1. Advanced Hydrophilic Coating: Proprietary hydrophilic lubricating coating becomes extremely slick upon hydration, dramatically lowering the coefficient of friction. This ensures smooth passage, enhances safety by reducing tissue damage, and improves overall procedural efficiency.

2. Flexible Tip Design: A soft, progressive tip offers superior flexibility, kink-resistance, and controlled maneuverability. Available in both straight and angled (J-tip) configurations to facilitate navigation through complex and tortuous anatomy.

3. Premium Material & Construction: Comprises a core of nickel-titanium (Nitinol) memory alloy, providing outstanding super-elasticity, pushability, and resistance to permanent deformation. The core is coated with a radiopaque polyurethane sheath containing high tungsten content, ensuring excellent and continuous visibility under fluoroscopy throughout its entire length.

4. Hemispherical Safety Tip: The tip is meticulously sealed into a smooth, rounded hemispherical shape, effectively safeguarding the urothelium and surrounding tissues from punctures, dissections, or other insertion-related injuries.

5. Low-Friction Surface: The entire surface is uniformly coated with the hydrophilic polymer, guaranteeing consistent, low-friction performance for unobstructed advancement and positioning.

Clinical Applications & Advantages

The hydrophilic urology guidewire represents a significant evolution from previous-generation devices like standard zebra guidewires. Its enhanced lubricity and atraumatic design not only improve smoothness but also substantially reduce the risk of accidental perforation and associated complications.

In modern urology, this guidewire is indispensable for a wide range of endoscopic diagnostic and therapeutic procedures. It is extensively used during ureteroscopy for guidewire-led access, placement of ureteral access sheaths, and subsequent insertion of ureteral stents or other instruments, playing a critical and often irreplaceable role.

Furthermore, it proves highly effective in managing challenging catheterization scenarios, such as difficult urethral catheter placements or the reinsertion of accidentally dislodged nephrostomy or cystostomy tubes. In these complex situations, where traditional techniques might fail—potentially necessitating surgical procedures like a percutaneous bladder puncture (cystostomy) or a new nephrostomy tube placement—the use of a hydrophilic guidewire has demonstrated a markedly high success rate. This helps avoid the risks, increased healthcare costs, and additional psychological burden associated with secondary surgeries.
