Comparing two methods for removing kidney stones
Part of Kidney & urinary clinical trials.
This study compares two ways to remove kidney stones: one uses a special scope to see and break up stones with a laser, and the other is a newer method. If you have stones up to 3 centimeters, this trial might help your doctor choose the safest and most effective approach.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have stones in the kidney or ureter (the tube that carries urine from the kidney to the bladder).
- The total size of your stones is 3 centimeters (about 1.2 inches) or less.
- You are scheduled to have the stones removed with a flexible scope through the urinary opening (called flexible ureteroscopy with laser).
- You do not have serious health problems that would make surgery risky, and you are not pregnant.

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 two ways to remove kidney stones: using a scope with a laser to break up stones, versus using the same scope plus a special gel to help remove the pieces. It aims to see if adding the gel makes the procedure more effective and safer.
This trial compares two ways of removing kidney stones during a procedure called flexible ureteroscopy. One method uses a special sheath that helps suction out stone fragments, which may improve stone removal and recovery.
This study compares a standard kidney stone removal procedure (ureteroscopy with laser) to a newer suction-based technology. If you have a kidney stone that needs surgery, this trial may help your doctor find the best way to remove it.
This study compares two methods used during surgery to remove kidney stones. It will see if a new device is as safe and effective as the standard one for breaking up and removing stones.
This study compares two methods for breaking up kidney stones smaller than 2 centimeters during a procedure using a flexible tube. The goal is to see which method is better at clearing stones and how it affects recovery.
