ILY Robotic System vs Manual Flexible Ureteroscopy for Kidney Stone Treatment

Not Applicable

Recruiting

• Conditions: Kidney Stones; Urolithiasis

• Registration Number: NCT06996587
• Lead Sponsor: Albert El Hajj

Brief Summary

The goal of this clinical trial is to compare the efficacy, ergonomics, and safety of robotic versus manual flexible ureteroscopy (fURS) for kidney stone treatment in adult patients undergoing laser lithotripsy.

* Does robotic-assisted lithotripsy using the ILY® robot have the same efficacy as the manual fURS in treating kidney stones?

* Is robotic flexible ureteroscopy associated with similar or improved safety outcomes, including perioperative and 30-day postoperative complication rates?

* Does the robotic system offer improved ergonomics, lower surgeon radiation exposure, and favorable intraoperative metrics compared to manual flexible ureteroscopy? Researchers will compare the ILY robotic system with manual fURS to see if robotic intervention can match or improve clinical and ergonomic outcomes.

Participants will:

* Be randomly assigned to undergo laser lithotripsy with either the ILY robot or manual flexible ureteroscopy

* Complete standard pre- and postoperative assessments

* Undergo evaluation for stone-free status using a non-contrast CT scan at 30 days postoperatively

* Undergo evaluation for postoperative complications

Primary Outcome Measures

Name	Time	Method
Efficacy assessed by measuring the stone-free rate (SFR)	30 days after the index procedure	A patient is considered stone free if there are no visible residual stone fragments after the treatment.

Secondary Outcome Measures

Name	Time	Method
Ergonomics	Immediately after the procedure	The NASA Task Load Index will be used to assess for ergonomics.
Intraoperative Parameters	During the procedure	Operative time, draping time, docking time, lasing time (all measured in minutes)
Perioperative and 30-day Postoperative Outcomes	Perioperatively and 30 days after the procedure	This assessment will account for any complications related to the patient's clinical condition from the procedure through a 4-week postoperative period.
Surgeon safety in terms of radiation exposure	During the procedure	Surgeon safety from ionizing radiation will be assessed by the surgeon wearing 3 dosimeter badges used to detect and record exposure.
Conversion rate	During the procedure	The proportion of cases where a procedure originally planned using the robotic technique had to be converted to manual fURS due to complications, technical difficulties, or failure of equipment.
