Description

This is a phase I feasibility study to investigate the use of a novel intelligent robotic retrograde intrarenal surgery (RIRS) platform. The TaloStone T1000 RIRS system can manipulate the flexible ureteroscope, with remote control of the instruments (laser fibre or basket) and ureteral access sheath movements. Beyond teleoperation, the TaloStone T1000 RIRS system integrates AI perception models and decision-making algorithms to enable the supervised autonomous execution of critical tasks within the RIRS workflow.

Interventions

  • RIRS using the TaloStone T1000 RIRS platform (Procedure)
    Retrograde intrarenal surgery (RIRS) will be performed using the TaloStone T1000 RIRS system. Beyond teleoperation, the TaloStone T1000 RIRS system integrates advanced AI perception models and decision-making algorithms to enable the autonomous execution of critical tasks within the RIRS workflow. The AI-based vision models coupled with sensors in the fURS allow real-time scene understanding, depth perception, stone size estimation, pressure and temperature feedback, and object tracking - thus establishing a robust foundation for higher level of surgical autonomy. Under supervision by the surgeon, the TaloStone T1000 RIRS system can perform supervised navigation into the collecting system, actively track a target stone, dynamically target the laser fibre tip towards a stone, plan the laser fragmentation route, and perform scope withdrawal for stone suction with re-entry.

Eligibility criteria

Severe concomitant illness that drastically shortens life expectancy or increases risk of therapeutic intervention 4. Untreated active infection 5. Un-corrected coagulopathy 6. Presence of another malignancy or distant metastasis 7. Emergency surgery 8. Vulnerable population (e.g. mentally disabled, pregnant)
