Medical specializations

Urolase series is a new generation of thulium fiber lasers (TFL), engineered to meet the evolving needs of urologists with a focus on versatility, precision, and safety.

 

Designed for both lithotripsy and soft tissue surgery, these systems offer enhanced control, optimized clinical modes, and integration-ready platforms for future functionality expansion.

 

Urolase MAX is the most powerful TFL system in its class, delivering up to 120 W of average power and supporting pulse energies up to 8 J with repetition rates approaching 5000 Hz. It introduces a high-power "Super Pulsed" mode (Super PALSD)—a new capability that builds on all legacy operating modes from earlier TFL generations, ensuring compatibility with familiar clinical workflows while unlocking advanced performance.

Key advantages

The Tissue Sensor is a real-time safety system that differentiates between stone and soft tissue at the fiber tip. It automatically deactivates laser emission upon detecting soft tissue, reducing the risk of injury and enhancing procedural safety during lithotripsy.
Urolase MAX features the first “Surgeon’s Assistant” in a laser platform—an intelligent system based on global clinical data that optimizes laser settings in real time to enhance safety and ensure consistent, expert-level outcomes.
Urolase MAX delivers high power in a compact, lightweight design—occupying half the space of comparable systems—making it ideal for modern operating rooms and outpatient settings, without compromising surgical capability, precision, or reliability.

Specifications

Technological features

  • Tissue Sensor is a proprietary innovation by VPGLaserOne, developed to maximize safety during stone lithotripsy. It supports the global trend toward minimally invasive, endoscopic treatment of urolithiasis.

    Tissue Sensor functions by identifying whether hard (stone) or soft (tissue) material is present in front of the surgical fiber tip. During lithotripsy, the laser automatically stops emission upon detecting soft tissue, effectively preventing mucosal injury and enhancing procedural safety.

     

    Surgeon's Assistant – intelligent parameter control

    Urolase MAX - the first laser system with a built-in “Surgeon’s Assistant” function, automatically adjusting laser parameters based on fiber type and treatment site. Developed from extensive data analysis of global surgical practices to maximize procedural safety.

     

    Full-spectrum lithotripsy efficiency

    Delivers all lithotripsy techniques—from high-speed dusting to large-fragment fragmentation—enabled by high power output and precision pulse modulation.

     

    “Fine” Mode – Ultra-Fine Dusting

    Pulverizes stones into fine dust rapidly, ideal for dusting strategies with minimal retropulsion.

     

    “Ultra” Mode – High-Energy Fragmentation

    Breaks down dense calculi into large fragments for lithoextraction, offering:

     

    • High fragmentation speed
    • Ultrasonic-level efficiency
    • Reduced operative time
    • Up to 100% stone-free rates

     

    Bloodless coagulation mode

    Special pulse profile provides wide-area, non-contact coagulation for safe and effective hemostasis in the postoperative field.

     

    Clean Pulse mode – carbonization-free vaporization

    Allows soft tissue vaporization and vapo-enucleation with no carbonization, preserving visibility and matching CW laser efficiency.

     

    Dual enucleation modes – vaporization & dissection

    Integrated enucleation platform with two optimized modes, enhanced by computer-modulated pulse shaping for precise control.

     

    Classic ThuFLEP

     

    • Efficient soft tissue vaporization
    • Minimal penetration for high surgical precision
    • Excellent hemostasis with virtually no blood loss

     

    Dissect Mode

     

    • Thermo-mechanical dissection similar to HoLEP
    • No carbonization
    • Hemostatic performance comparable to ThuFLEP
