About this trial
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
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Males or females ≥ 18 years old
Patients with a normal pelvicalyceal anatomy
Patients with renal stone diagnosis confirmed by noncontrast computed tomography regardless of stone size, location, and multiplicity
ASA score I-III
Disqualifiers
Children < 18 and pregnant women
Patients with anatomically anomalous kidneys, known case of stricture or stenosis, or recent 3-month history of ureteroscopy (DJ stent placement only will be accepted) or known history of complicated ureteroscopy
Patients in whom stone measurement was not feasible on NCCT or those with concomitant ureteric stones.

Treatments tested in this trial
Robotic-Assisted Flexible Ureteroscopy
Procedure/SurgeryUse of the ILY® robotic system to perform flexible ureteroscopy.
Manual Flexible Ureteroscopy
Procedure/SurgeryConventional flexible ureteroscopy performed manually by the surgeon.
Treatment groups
Trial outcomes
Primary outcomes
Efficacy assessed by measuring the stone-free rate (SFR)
A patient is considered stone free if there are no visible residual stone fragments after the treatment.
Secondary outcomes
Perioperative and 30-day Postoperative Outcomes
This assessment will account for any complications related to the patient's clinical condition from the procedure through a 4-week postoperative period.
Ergonomics
The NASA Task Load Index will be used to assess for ergonomics.
Surgeon safety in terms of radiation exposure
Surgeon safety from ionizing radiation will be assessed by the surgeon wearing 3 dosimeter badges used to detect and record exposure.
Intraoperative Parameters
Operative time, draping time, docking time, lasing time (all measured in minutes)
