Summary
Holmium laser lithotripsy safely and effectively treats all urinary tract stones. This endoscopic approach cleared all calculi in a clinical series, with high success rates in single-session treatments for ureteral and renal stones.
Area of Science:
- Urology
- Laser Medicine
- Endourology
Background:
- Urinary tract calculi pose a significant clinical challenge.
- Endoscopic lithotripsy aims for minimally invasive stone removal.
Purpose of the Study:
- To evaluate the safety and efficacy of holmium laser energy as an endoscopic lithotrite for urinary tract calculi.
Main Methods:
- Prospective data collection over 2 years from patients undergoing endoscopic holmium laser lithotripsy.
- Utilized holmium lasers of varying outputs (15-60W) with specialized quartz fiber delivery systems.
- Employed various combinations of endoscopes and laser fibers for different stone locations and types.
Main Results:
- Successfully cleared all 75 calculi in 63 patients endoscopically.
- High single-session treatment success rates: 97% for ureteral calculi and 88.5% for retrograde renal calculi.
- No complications, including ureteral stricture disease, were observed.
- Effective treatment of complex, large calculi, including lower-pole renal and bladder stones.
- Resolution of chronic urinary infections in some patients post-treatment.
Conclusions:
- Holmium laser energy is a safe and effective modality for treating all types of urinary calculi.
- The endoscopic application of holmium laser lithotripsy offers high success rates and minimal complications.
