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.

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+ Premium is a next-generation thulium fiber laser system equipped with an advanced tissue detection sensor to enhance safety during surgical procedures. It uniquely supports two enucleation techniques in a single platform:

Classic thulium fiber enucleation (ThuFLEP) – continuous-wave laser-based technique for precise tissue resection
"Dissect" mode – thermo-mechanical dissection for controlled, layered tissue separation

This dual-mode capability offers greater procedural flexibility, allowing surgeons to tailor their approach based on anatomical and clinical requirements.

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+ Premium features a unique pulse mode that enables efficient, non-contact coagulation over a broad area—ideal for managing postoperative bleeding with precision and minimal thermal impact.

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.

Modulated pulse technology – enables ultra-efficient lithotripsy with “Fine” dusting and “Ultra” fragmentation modes
Dual enucleation capability – supports both “Dissect” mode and classic ThuFLEP technique in one device
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)

Standard mode ThuFLEP

Enucleation mode «DissectPulse»

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+ Premium 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
Bloodless coagulation mode

A dedicated pulse profile enables wide-area, non-contact coagulation, ensuring effective hemostasis from a short distance without thermal damage to adjacent tissue.

Dual enucleation capabilities

Urolase+ Premium features an advanced prostate enucleation platform based on computer-modulated pulse control—supporting both vaporization and dissection techniques.

Classic ThuFLEP Mode

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

Dissect mode – thermo-mechanical enucleation

• Clean dissection of adenomatous tissue with no carbonization • Surgical handling similar to HoLEP • Hemostatic performance comparable to ThuFLEP
