Summary
Pulsed dye laser treatment for ureteric stones is effective and safe. Ureteroscopic lasertripsy achieved an 84% success rate, though some stones were flushed back into the kidney.
Area of Science:
- Urology
- Laser Medicine
Background:
- Ureteric stones pose a significant clinical challenge.
- Minimally invasive treatments are preferred for stone removal.
Purpose of the Study:
- To evaluate the efficacy and safety of pulsed dye laser treatment for ureteric stones.
- To compare ureteroscopic lasertripsy with "blind" lasertripsy.
Main Methods:
- Retrospective analysis of 120 patients treated with pulsed dye laser.
- 107 patients underwent ureteroscopic lasertripsy.
- 13 patients underwent "blind" lasertripsy.
Main Results:
- Ureteroscopic lasertripsy demonstrated an 84% success rate.
- Failure in ureteroscopic lasertripsy was primarily due to stone retropulsion into the kidney (14%).
- "Blind" lasertripsy had a lower success rate of 23% but was safe.
Conclusions:
- Pulsed dye laser, particularly via ureteroscopy, is an effective and safe modality for ureteric stone treatment.
- Ureteroscopic approach offers a high success rate, with retropulsion being a key factor in treatment failure.
- Further optimization may be needed to address stone mobility during ureteroscopic lasertripsy.
