Ureterorenal endoscopy: which instrument, what cost?

Area of Science:

• Urology
• Medical Device Engineering

Background:

• Rigid ureteroscopes are crucial surgical instruments.
• Understanding their design and performance is vital for clinical application.

Purpose of the Study:

• To comprehensively review the design, availability, repair, and costs of rigid ureteroscopes.
• To introduce a novel method for assessing ureteroscope flow dynamics.
• To classify ureteroscopes based on clinical factors and performance.

Main Methods:

• Detailed analysis of rigid ureteroscope design features and clinical considerations.
• Development and description of a new test for evaluating flow dynamics.
• Classification of ureteroscopes based on telescope system stability and operating length.

Main Results:

• Short operating rigid ureteroscopes with stable or integral telescope systems demonstrate superior performance.
• The new flow dynamics test provides a standardized method for assessment.
• Specific design factors influencing clinical utility are identified.

Conclusions:

• Rigid ureteroscopes with stable, short designs are recommended for antegrade ureteroscopy.
• Further research into ureteroscope design can optimize surgical outcomes.
• The described classification and testing methods aid in device selection and development.
