Holmium:YAG Laser Lithotripsy System

Product Introduction

The Holmium:YAG laser lithotripsy system is a minimally invasive surgical laser device used in urology for fragmentation and removal of urinary tract stones, including kidney stones, ureteral stones, and bladder stones.

It operates at a wavelength of 2100 nm, which is highly absorbed by water in biological tissues, allowing precise and controlled stone fragmentation with minimal penetration depth and reduced risk to surrounding tissue. This system is widely recognized as the gold standard laser technology in modern endourology.

What is Holmium:YAG Laser?

The Holmium:YAG (Ho:YAG) laser is a pulsed solid-state medical laser applied for endoscopic urological procedures, with core characteristics as follows:

• Wavelength: 2100 nm (infrared spectrum)
• High absorption rate by water
• Shallow tissue penetration (~0.3–0.4 mm)
• Dual functions for stone fragmentation and dusting
• Compatible with both flexible and rigid endoscopes

Key Advantages

High-Efficiency Stone Fragmentation

Laser energy is delivered via optical fibers to crush stones into tiny fragments or dust, facilitating natural excretion by patients.

Minimal Thermal Injury

The shallow tissue penetration depth greatly lowers thermal damage to adjacent normal tissues and improves surgical safety.

Versatile Clinical Modes

Supports multiple mature lithotripsy operation modes:

• Fragmentation mode (high energy, low frequency)
• Dusting mode (low energy, high frequency)
• Popcorning technique for residual stone clearance

Full Endoscopic Compatibility

Matches mainstream endoscopic equipment:

• Flexible ureteroscopes (fURS)
• Rigid ureteroscopes
• PCNL (Percutaneous Nephrolithotomy) systems

Global Clinical Gold Standard

Accepted as the universal preferred intracorporeal lithotripsy laser by urology departments worldwide.

Clinical Applications

Urinary Stone Diseases

• Renal calculi (kidney stones)
• Ureteral stones
• Bladder stones

Urological Surgical Procedures

• Endoscopic ureteroscopic lithotripsy (URS)
• Percutaneous nephrolithotomy (PCNL)
• Ureteral stricture incision
• Selective bladder tumor ablation

Advanced Endourology Operations

• Stone dusting and complete fragmentation
• Auxiliary ureteral reconstruction
• General minimally invasive urological surgeries

Technical Overview

Why Holmium Laser Is Regarded As Gold Standard

Compared with ultrasonic, pneumatic and electrohydraulic lithotripsy equipment, Ho:YAG laser delivers the following superiorities:

• Precise controllability over stone fragmentation effect
• Lower risk of ureteral wall laceration and injury
• Strong adaptability to various endoscopic devices
• Wider coverage of clinical treatment scenarios
• Higher stone clearance success rate in flexible ureteroscopy
