Comparing HugeMed Ureteroscope for Kidney Stones

This study is looking at how well a specific flexible ureteroscope, the HugeMed 6.3 Fr f-URS, works compared to other standard ureteroscopes for treating kidney and ureteral stones. Researchers want to see if using the HugeMed device can lead to similar successful stone removal rates while also being more cost-effective. You might be able to join if you are 18 or older, have kidney or ureteral stones, and are having a procedure called retrograde intrarenal surgery (RIRS) where a scope goes up to the kidney. Your total stone size should be 2.5 cm or less. The study will compare outcomes and costs over 36 months. The current recruitment status is unclear.
