What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to determine the differences in stone free results, patient side effects, and patient satisfaction between dusting vs. basket extraction for kidney and ureteral stones (a kidney stone located in the tube between the kidney and bladder) 6 mm and greater in size undergoing ureteroscopic treatment.Dusting is when a laser is used to break a stone down into tiny fragments that are able to pass through the urine. Basket extraction is when a small wire basket is used to remove stone fragments.

What Are the Treatments Tested in This Trial?
