Single use flexible ureteroscopes: Current status and future directions.

Area of Science:

• Urology
• Medical Devices
• Surgical Technology

Background:

• Single-use ureteroscopes represent a recent innovation in urology, gaining significant traction over the past decade.
• An increasing body of research, including benchside and clinical studies, is emerging on their performance and application.

Purpose of the Study:

• To provide a comprehensive narrative review of single-use ureteroscope technology.
• To examine the historical development, technical specifications, and comparative advantages/disadvantages of these devices.

Main Methods:

• A narrative review methodology was employed.
• The review synthesized findings from preclinical and clinical studies, focusing on device design, outcomes, and cost-effectiveness.

Main Results:

• Preclinical studies suggest design advantages like lower weight and pressure control, but environmental concerns persist.
• Clinical studies indicate non-inferior stone-free rates compared to reusable scopes, though evidence from randomized trials is limited.
• Cost analyses remain conflicting, necessitating site-specific evaluations.

Conclusions:

• Current clinical outcomes for single-use ureteroscopes are largely comparable to reusable counterparts, but the supporting evidence base is still developing.
• Key areas for ongoing discussion and research include the environmental impact and economic viability of single-use ureteroscopes.
