Summary

Ureteroscopic lithotripsy using the Swiss Lithoclast system effectively fragments ureteral stones in 91% of cases. This minimally invasive treatment is also cost-effective compared to laser lithotripsy.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Medical Device Technology

Background:

  • Ureteral stones pose a significant clinical challenge.
  • Ureteroscopic lithotripsy is a common treatment for ureteral stones.
  • Evaluating new lithotripsy technologies is crucial for improving patient outcomes and cost-effectiveness.

Purpose of the Study:

  • To prospectively evaluate the efficacy and cost-effectiveness of the Swiss Lithoclast system for ureteral stone fragmentation.
  • To determine the stone-free rate following ureteroscopic lithotripsy with the Lithoclast system.

Main Methods:

  • Prospective study of 74 patients undergoing ureteroscopic lithotripsy.
  • Utilized Wolf ureteroscopes (7.5F or 9F) with the Swiss Lithoclast system.
  • Dormia baskets used for fragment retention; adjuvant shock wave lithotripsy (SWL) considered for partial fragmentation.

Main Results:

  • Successful ureteroscopic access in 95% of patients.
  • Successful Lithoclast lithotripsy in 92% of cases.
  • Complete fragmentation achieved in 91% of treated patients, with a 96% stone-free rate at 6 weeks.
  • Overall fragmentation rate reached 91% with adjuvant SWL.
  • Lithoclast system demonstrated a three-fold cost advantage over Candela lasertripsy.

Conclusions:

  • Ureteroscopic Lithoclast lithotripsy is a highly effective treatment for ureteral stones.
  • The procedure achieves high fragmentation and stone-free rates.
  • The Swiss Lithoclast system offers a cost-effective alternative to laser lithotripsy for ureteral stone management.
