New flexible ureterorenoscopes with working channels offer effective treatment for upper urinary tract stones. Continued development is needed to expand their clinical applications beyond stone removal.

Area of Science:

  • Urology
  • Medical Devices
  • Endoscopy

Background:

  • Clinical use of flexible ureterorenoscopes has lagged behind rigid scopes.
  • Development of flexible endoscopes with working channels enables therapeutic interventions.

Purpose of the Study:

  • To highlight the clinical utility of newly developed flexible ureterorenoscopes.
  • To discuss the potential applications and necessary improvements for flexible ureterorenoscopes.

Main Methods:

  • Description of the capabilities and application of flexible ureterorenoscopes.
  • Discussion of the advantages over rigid endoscopes for specific stone locations.
  • Consideration of safety precautions during instrument insertion.

Main Results:

  • Flexible ureterorenoscopes are effective for treating upper urinary tract stones, including mobile stones and those in renal calices.
  • The instrument can be used for foreign body removal and diagnosis/treatment of small pathologies.
  • Potential for damage is minimal if proper technique and calmness are maintained.

Conclusions:

  • Flexible ureterorenoscopes offer a valuable tool for upper urinary tract stone management and other urologic conditions.
  • Further improvements in image resolution, angulation, accessories, and urologist familiarity are crucial for broader adoption.
