Digital flexible ureterorenoscopy offers superior visualization for upper urinary tract lithiasis treatment. This new technology significantly improves upon traditional fiberoptic flexible ureterorenoscopy (URS) for stone removal.

Area of Science:

  • Urology
  • Medical Devices
  • Endoscopy

Background:

  • Flexible ureterorenoscopy (URS) is a popular minimally invasive treatment for upper urinary tract stones.
  • Current fiberoptic technology in flexible URS has limitations in visualization and scope fragility.
  • Improving visualization is key to enhancing flexible URS procedures.

Purpose of the Study:

  • To evaluate the initial clinical experience with a novel digital flexible ureterorenoscope.
  • To assess the efficacy and image quality of digital flexible URS with holmium laser lithotripsy.
  • To compare digital flexible URS with traditional fiberoptic systems.

Main Methods:

  • Initial experience with digital flexible URS and holmium laser lithotripsy in three patients.
  • Two patients with upper tract calculi (lower pole and caliceal diverticular stones) were treated.

Related Experiment Videos

  • One patient underwent diagnostic digital flexible URS.

    • Main Results:

    • Complete stone destruction was achieved in both patients with calculi.
    • Digital flexible URS demonstrated remarkable improvement in image quality compared to fiberoptic URS.
    • Minor image interference occurred during fluoroscopy and laser activation.

    Conclusions:

    • The digital flexible ureteroscope offers excellent image quality and zoom capabilities, surpassing fiberoptic technology.
    • This digital scope eliminates the need for a separate light source.
    • Digital flexible URS represents a significant advancement for treating upper urinary tract conditions.
