Urology

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.

Optimized for advanced urological procedures, Urolase+ integrates a tissue detection sensor to enhance intraoperative safety and features modulated pulse modes tailored for efficient and precise lithotripsy:

MRP Mode – minimizes retropulsion through controlled energy modulation
"Fine" mode – enables ultra-fast stone dusting into microfragments
"Ultra" fragmentation mode – effectively breaks down dense stones into large, extractable fragments

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.

The Urolase series uses a thermal stress-based fragmentation mechanism to ensure efficient and precise stone disintegration, with exceptional performance on dense calculi.

Enables instant, contamination-free fiber connection with an auto shutter and status indicator—no screwing required. Ensures easy, reliable setup and quick fiber changes during procedures.

Air-cooled system – efficient thermal management without external water cooling
Standard power compatibility: operates on standard 220V—no special infrastructure required
Maintenance-free operation – engineered for long-term reliability without routine servicing
High power in a compact design—up to 4× smaller than comparable Ho:YAG systems.

How laser works

Secure PCNL with Tissue Sensor: 550 µm fiber, 3 J × 13 Hz (39 W), stone density 1640 HU. Footswitch held continuously; energy auto-interrupted

Examination of the mucosa after stone crushing revealed no visible damage

UltraPulse mode fragmentation during transurethral cystolithotripsy 60 J at 1 Hz (60 W)

UltraPulse mode utilizes thermal stress for efficient and safe stone fragmentation during Percutaneous Nephrolithotripsy (PCNL) at 30 J, 1 Hz (30 W)

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.

Versatile lithotripsy performance

Urolase+ supports all laser lithotripsy techniques—from fine dusting to fragmentation for lithoextraction—enabled by modulated pulse control and high-output energy delivery.

“Fine” mode – high-speed dusting

Precisely pulverizes stones into ultra-fine dust, minimizing retropulsion and enhancing procedural speed.

“Ultra” mode – high-energy fragmentation

Instantly breaks down dense calculi into large fragments, ideal for lithoextraction:
- High fragmentation speed
- Efficiency comparable to ultrasonic lithotripters
- Reduced procedure time
- Enables up to 100% stone-free outcomes
