Clinical Scorecard: Comparative Evaluation of the Vortex Intelligent Stone Optimized Removal (VISOR) System and the Flexible Navigable Suction Ureteral Access Sheath (FANS) for Stone Clearance and Intrarenal Pressure Management in vitro

At a Glance

Key Highlights

• VISOR system allows concurrent irrigation and suction during laser lithotripsy
• Potential to improve single-session stone clearance efficiency
• Automated intrarenal pressure regulation may reduce complications
• FANS techniques require repeated scope withdrawal, increasing fatigue
• Study compares VISOR and FANS in a controlled 3D-printed renal model

Guideline-Based Recommendations

Diagnosis

• Utilize imaging techniques like CTU for accurate assessment of kidney stones

Management

• Consider RIRS as a first-line treatment for stones up to 2 cm

Monitoring & Follow-up

• Implement real-time intrarenal pressure monitoring during procedures

Risks

• Be aware of potential complications such as pyelovenous backflow and urosepsis

Patient & Prescribing Data

Patients undergoing treatment for kidney stones

VISOR may offer ergonomic advantages and improved outcomes over traditional methods

Clinical Best Practices

• Employ dual-channel ureteroscopes for enhanced stone removal efficiency
• Integrate automated systems for pressure monitoring and fluid regulation
• Standardize laser settings to isolate the influence of suction technology
