This is a prospective randomized clinical trial which aims to compare the clinical outcomes of robotic flexible ureteroscopy and standard flexible ureteroscopy for the treatment of renal stones.
This is a prospective randomized controlled trial comparing robotic flexible ureteroscopy and standard flexible ureteroscopy for patients with treatment of renal stones. All consecutive patients who are scheduled for flexible ureteroscopy for treatment of renal stones would be screened for study eligibility. Patients are randomised to receive either robotic or standard flexible ureteroscopy with an allocation ratio of 1:1. by computer generated random block. The urologist performing the surgery could not be blinded due to the nature of the intervention. Patients receiving the treatment and investigators assessing for any disease recurrence are blinded from the allocated treatment arm.

RECRUITINGStone-free rate at 1 month
Stone-free rate at 1 month is defined by non contrast computer tomography (NCCT) performed within 24 hours of surgery without residual stone fragments or residual stone fragments \<2mm
Time frame: Month 1
Stone-free rate at 3 month
If not stone free at 1 month, stone-free rate at 3 month is defined by non contrast computer tomography (NCCT) performed within 24 hours of surgery without residual stone fragments or residual stone fragments \<2mm
Time frame: Month 3
