A prospective, single-blind, randomized controlled trial was conducted on 90 patients who underwent RIRS. Results showed no significant difference in the success rate and complications between the two groups (with UAS and without UAS) in terms of stone-free rate, operative time and complications. The study concludes that the use of UAS does not affect the success of RIRS for renal stones.
