Area of Science:

  • Urology
  • Endourology
  • Medical Device Technology

Background:

  • Intracorporeal lithotripsy utilizes various devices for stone fragmentation.
  • Recent advancements focus on improving efficacy, safety, and applicability of lithotripters.

Purpose of the Study:

  • To review and compare intracorporeal lithotripter devices.
  • To analyze their advantages, disadvantages, efficacy, safety, and clinical applications.
  • To discuss future development trends in lithotripsy technology.

Main Methods:

  • Systematic review of recent literature on intracorporeal lithotripters.
  • Comparative analysis of different lithotripter types based on published data.
  • Evaluation of clinical outcomes, including fragmentation and stone-free rates.

Main Results:

  • Ultrasound lithotripsy via rigid endoscopes shows high fragmentation (97-100%) and stone-free rates (94%).
  • Combined ultrasound and pneumatic lithotripsy demonstrates 80-89.7% stone-free rates with no major complications.
  • Holmium:YAG laser lithotripsy is effective for all stone compositions, especially ureteral stones (near 100% stone-free rate), with minimal complications.

Conclusions:

  • Ultrasound lithotripsy remains the preferred method for rigid endoscopic procedures.
  • Combination ultrasound and pneumatic lithotripters offer combined benefits.
  • Holmium:YAG laser lithotripsy is the optimal choice for flexible endoscopic treatments.
  • Continued development of novel lithotripters and energy source combinations is essential.
