The Swiss Lithoclast is a safe and effective tool for breaking up urinary stones. This jackhammer-like device successfully treated 90% of calculi in 20 patients, with 17 becoming stone-free.

Area of Science:

  • Urology
  • Medical Devices
  • Nephrology

Background:

  • Urinary calculi (stones) pose a significant clinical challenge.
  • Intracorporeal lithotripsy offers a minimally invasive treatment option.
  • Existing lithotripsy methods may have limitations.

Purpose of the Study:

  • To evaluate the safety and efficacy of the novel Swiss Lithoclast device for intracorporeal lithotripsy.
  • To assess the fragmentation rate and stone-free status after treatment with the Swiss Lithoclast.

Main Methods:

  • The Swiss Lithoclast, a compressed air-powered device, was used for intracorporeal lithotripsy.
  • Twenty patients with ureteral, bladder, or Kock pouch stones were treated.
  • Success was defined by stone fragmentation and subsequent stone-free status.

Main Results:

  • The Swiss Lithoclast successfully fragmented 90% of calculi, irrespective of composition.
  • The device was effective in salvaging two cases of failed extracorporeal shock wave lithotripsy (ESWL).
  • At one month post-procedure, 17 out of 20 patients achieved stone-free status.

Conclusions:

  • The Swiss Lithoclast is a safe and effective device for intracorporeal lithotripsy of urinary calculi.
  • It offers a viable treatment option, alone or in conjunction with ESWL.
  • No complications were associated with the use of the Swiss Lithoclast.
