Endoscopic stone removal is a viable minimally invasive option. The best lithotripsy method depends on stone location and endoscope type, balancing effectiveness with instrument limitations.

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Extracorporeal shockwave lithotripsy is common, but endoscopic stone removal remains crucial for specific cases.
  • No single lithotripsy technique is universally optimal for all endoscopic stone disintegration procedures.

Purpose of the Study:

  • To analyze factors influencing the selection of lithotripsy methods for endoscopic stone removal.
  • To highlight the impact of endoscope characteristics and probe design on procedure effectiveness.

Main Methods:

  • Review of current endoscopic lithotripsy techniques and their applications.
  • Analysis of probe characteristics (calibre, flexibility) and their compatibility with different endoscopes (ureteroscopes).

Main Results:

  • Stone localization is a primary determinant for choosing lithotripsy. Small, flexible probes (electrohydraulic, pneumatic, laser) suit ureteroscopy but have slower disintegration rates.

  • Large, rigid probes (ultrasound) offer higher efficacy but are incompatible with flexible ureteroscopes.
  • Endoscope type, instrument flexibility, and working channel diameter significantly influence device selection.

    • Conclusions:

    • The choice of endoscopic lithotripsy is dictated by a combination of stone characteristics, anatomical location, and available endoscopic equipment.
    • Optimizing stone disintegration requires careful consideration of the interplay between probe technology and endoscope design, alongside cost-effectiveness of disposable materials.
