In vitro lithotripsy with the Alexandrite laser.

Area of Science:

• Urology
• Laser Medicine
• Nephrolithiasis Treatment

Background:

• Ureteral lithotripsy is a common procedure for kidney stone removal.
• Recent concerns exist regarding fiber splintering during Alexandrite laser lithotripsy with high power densities.
• The Alexantriptor (HMT) model has been developed for Alexandrite laser lithotripsy.

Purpose of the Study:

• To evaluate the safety and efficacy of Alexandrite laser lithotripsy.
• To investigate the risk of fiber splinter interspersion into ureteral tissue.
• To assess potential ureteral damage during the procedure.

Main Methods:

• In vitro lithotripsy performed on artificial renal calculi within human ureter models.
• Utilized the Alexantriptor (HMT) manufactured model for Alexandrite laser lithotripsy.
• Evaluated for interspersion of fragments and ureteral tissue damage.

Main Results:

• No instances of fiber splinter interspersion into ureteral tissue were observed.
• No significant ureteral damage was detected during the in vitro experiments.
• The procedure demonstrated a lack of adverse tissue reactions.

Conclusions:

• Alexandrite laser lithotripsy, using the parameters tested, is a safe and reliable method.
• The risk of fiber splintering appears minimal under these conditions.
• Clinical experience supports the safety and efficacy of this lithotripsy technique.
