Comparing Sizes of Ureteroscopes for Kidney Stone Laser Treatment
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study compares two different sizes of flexible ureteroscopes to treat kidney and upper ureter stones using a laser. The goal is to see which size works better while keeping similar stone-breaking power.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have kidney stones or stones in the upper ureter with a total size less than 3 cm (about 1.2 inches).

This trial compares two types of lasers used to break up kidney and ureter stones during a ureteroscopy procedure. The goal is to see which laser works better at breaking stones into smaller pieces.
This trial compares two types of disposable flexible ureteroscopes to see which works better for removing kidney stones in children. If your child has a single kidney stone or multiple stones that add up to less than 20 mm, this study may help guide better treatment.
This trial tests a new device called VISOR to help break up kidney stones using a flexible tube and laser. It's for adults aged 18–80 with stones between 1 and 3 cm who haven't had previous kidney surgery.
This study compares different types of flexible ureteroscopes used to remove kidney stones. It looks at how well they work and their safety.
This study compares two types of laser treatments used during a minimally invasive procedure to break up kidney stones. You would be randomly assigned to receive one of the two lasers to help doctors understand which works better for stone removal.
This trial tests a specific flexible scope (Shenzhen HugeMed 6.3 French) for removing kidney or ureter stones. It looks at how well it works, costs, and recovery, and may be a good option if you have stones smaller than 2.5 cm and need your first such surgery.
