Summary
Laser lithotripsy effectively fragments ureteric stones in 77% of patients. This safe and efficient treatment complements other stone removal methods, offering a viable option for various stone locations.
Area of Science:
- Urology
- Medical Technology
Background:
- Ureteric stones pose a significant clinical challenge.
- Effective and safe treatment modalities for ureteric stones are continuously sought.
Purpose of the Study:
- To evaluate the efficacy and safety of the Candela MDL-2000 LaserTripter for ureteric stone fragmentation.
- To assess the treatment outcomes across different ureteric stone locations.
Main Methods:
- Prospective study of 200 patients treated with laser lithotripsy.
- Utilized a Candela MDL-2000 LaserTripter and 7.2F Miniscope.
- Evaluated stone fragmentation success, need for auxiliary procedures, and complication rates.
Main Results:
- Successful laser fragmentation achieved in 77% of 175 evaluable patients.
- An additional 10% became stone-free with the push-bang technique.
- Ureterolithotomy was required in 9%, with a major complication rate of 4%.
Conclusions:
- Laser lithotripsy with the Candela MDL-2000 system is highly effective and safe for ureteric stones at all levels.
- This modality complements ultrasound-guided extracorporeal lithotripsy.
- No stone was encountered that could not be broken.
