Lasertripsy for Ureteric Stones in 120 Cases: Lessons Learned

The pulsed dye laser has proved to be an effective and safe method of treating ureteric stones; 120 patients have been treated. Ureteroscopic lasertripsy (107 cases) had an overall success rate of 84%. The failures were due to mobile stones inadvertently flushed back into the kidney (14%) and 2% of patients required open ureterolithotomy after failure of two ureteroscopic procedures. "Blind" lasertripsy (13 cases) was safe but not as efficient, the success rate being only 23%.
