Why Maneuverability Matters in Choosing a Flexible Ureteroscope
A 2025 randomized trial comparing a slim 6.3 Fr ureteroscope with a standard 7.5 Fr model found that the slimmer, more maneuverable device achieved higher stone-free rates and shorter operative times, largely due to improved deflection and easier access to difficult calyces.
Understanding Flexible Ureteroscopes
The urinary tract is a highly complex pathway. Sharp angles, narrow channels, and delicate tissue all create challenges for urologists.
Maneuverability directly addresses these issues by:
- Improving access to complex anatomy: A highly maneuverable scope can reach upper pole kidney stones or calyces hidden at acute angles.
- Reducing surgeon fatigue: When the scope responds smoothly, surgeons spend less energy making micro-adjustments, even during long procedures.
- Shortening operative times: Efficient navigation reduces delays, which benefits both patients under anesthesia and operating room schedules.
- Enhancing procedural precision: Fine control improves targeting for stone fragmentation, laser therapy, and biopsies.
Evidence supports these benefits. In one ergonomic study, the force required to fully deflect different ureteroscopes varied from as little as 5 newtons to more than 30. Scopes that required greater force not only increased surgeon strain but also raised the risk of pushing too hard against delicate tissue.
What Biomedical Teams Should Know About Ureteroscope Maneuverability
While maneuverability is often evaluated from the surgeon’s perspective, it also matters to biomedical engineers and OR support teams responsible for evaluating, maintaining, and integrating new scopes into clinical workflows.
A flexible ureteroscope that maintains its deflection performance after repeated sterilization cycles, or, in the case of single-use scopes, delivers consistent performance across units, helps reduce service interruptions, and supports long-term value.
Durability is closely linked to maneuverability. Scopes that bend smoothly under load, with minimal resistance, are less likely to suffer cable damage or loss of angulation over time. In facilities with high ureteroscopy volumes, these factors contribute to fewer scope failures and more predictable cost planning.
In single-use devices like the Macrolux flexible ureteroscope, consistent deflection, stable image quality, and built-in ergonomic controls help standardize performance across procedures, simplifying support and reducing downtime.
For biomedical teams, this means fewer reactive repairs and greater confidence in how each case will unfold.
Maneuverability and Patient Safety
Patient safety is the ultimate measure of surgical technology. A flexible ureteroscope with superior maneuverability contributes to safety in several ways:
- Lower complication risk: Reduced force during navigation decreases the chance of perforation or trauma to the ureter and kidney.
- More complete stone clearance: Surgeons can reach hidden areas, reducing the likelihood of residual fragments that may require follow-up procedures.
- Better visualization: Smooth scope control enhances positioning, improving image stability and treatment accuracy.
- Faster recovery: Less tissue trauma often correlates with less postoperative discomfort and quicker discharge.
Safety is also a long-term value driver. In the 2025 slim scope study, both devices demonstrated low complication rates, with only minor and transient issues such as mild hematuria.
This suggests that maneuverability enhancements can be achieved without compromising safety, and may even support gentler, less traumatic procedures.
Evaluating Flexible Ureteroscope Designs
When comparing flexible ureteroscopes, decision-makers should pay close attention to maneuverability-related features:
- Deflection range: Look for wide deflection (up to 270° or more) to ensure complete access to all calyces of the kidney.
- Rotation capability: Ergonomic shaft rotation helps surgeons align instruments quickly without constant wrist repositioning.
- Image quality under deflection: Some scopes lose clarity when fully bent; premium designs maintain consistent resolution.
- Durability and serviceability: Frequent reprocessing and use in high-volume centers demand robust construction.
- Ease of use: Intuitive controls facilitate easier adoption for surgical teams with varying levels of experience.

Looking Ahead: The Future of Flexible Ureteroscopy
As endourology evolves, so do the expectations placed on surgical devices. Flexible ureteroscopes are no longer evaluated solely on deflection or image quality. They’re increasingly seen as part of a broader push toward smarter, safer, and more streamlined procedures.
Miniaturization is accelerating. Manufacturers are engineering slimmer scopes that preserve maneuverability while reducing ureteral trauma. Devices in the 6.5 to 7.5 Fr range are becoming increasingly common, offering easier access with reduced need for dilation, especially in tight or tortuous anatomy.
Single-use scopes are gaining traction. As hospitals strive to minimize infection risks and streamline logistics, disposable scopes provide consistent performance without the variability introduced by repeated sterilization.
Macrolux’s ureteroscopes are designed for single use, maintaining high deflection and optical quality from case to case without compromise.
Digital imaging is advancing. High-resolution CMOS sensors, wide-angle lenses, and better color accuracy are improving procedural visibility.
In the future, these features may integrate with AI-assisted navigation or automated performance feedback, innovations that rely on stable and precise maneuverability.
Durability remains a priority. Even as scopes become smaller and more advanced, their performance must remain reliable across all uses. Whether reusable or single-use, surgeons expect consistent torque response, deflection integrity, and optical clarity under load.
With its focus on extended deflection range, ergonomic control, and dependable performance, the Macrolux flexible ureteroscope is well-aligned with the next generation of ureteroscopic care.
Final Considerations for Dealers and Surgical Teams
Introducing a new ureteroscope is a decision that balances cost, usability, and long-term outcomes.
