High-frequency laser lithotripsy for kidney stones, despite technological advances, shows similar clinical outcomes to lower-power lasers. Further research is needed to fully understand its potential in urolithiasis treatment.
Area of Science:
- Urology
- Laser technology
- Endoscopic surgery
Background:
- The Holmium:YAG (Ho:YAG) laser transformed endoscopic urolithiasis treatment over 30 years ago.
- Innovations led to high-power lasers for high-frequency lithotripsy, aiming for improved stone-free rates.
Approach:
- This review analyzes the clinical utility of high-frequency laser lithotripsy.
- It compares outcomes with established lower-power laser lithotripsy techniques.
Key Points:
- In vitro studies suggested significant potential for high-frequency lithotripsy.
- Clinical literature reveals comparable outcomes between high and lower power laser lithotripsy.
- The clinical benefit of high-frequency lithotripsy has not consistently matched in vitro expectations.
Conclusions:
- Current evidence suggests high-frequency laser lithotripsy offers similar efficacy to lower-power lasers in clinical practice.
- The evolution of Ho:YAG laser technology requires further investigation to optimize its application in treating urolithiasis.
