Comparing two keyhole surgeries for medium kidney stones
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This trial compares two minimally invasive surgeries for removing kidney stones that are 2–3 cm in size. One uses a special vacuum to help clear stone fragments, and the other uses suction. Both are done through a small tube in the back, and the goal is to see which approach is safer and more effective.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older.
- You have one or more kidney stones that are between 2 and 3 centimeters (about the size of a large grape).
- You do not have a urinary tract infection before surgery (a simple urine test can confirm).
- You can safely receive general anesthesia (being put to sleep) or spinal anesthesia (numbing from the waist down).
- You sign a consent form agreeing to take part.
- You do not have certain kidney shape problems, severe narrowings, or bleeding risks that would make the procedure unsafe.

This study compares two ways to remove kidney stones: mini-PCNL (a small incision in your back) versus flexible ureteroscopy with a suction sheath (a tube through the urinary tract). It aims to find which method works better and is safer for stones of this size.
This study compares two minimally invasive procedures to remove small-to-medium kidney stones (1 to 2.5 cm). The goal is to see which method is safer and more effective, possibly leading to quicker recovery and fewer side effects.
This study compares two methods for removing kidney stones when they are too large or complex for other treatments. Both methods use a small cut in the back to reach the kidney, and the goal is to find which approach works better with fewer complications.
This trial compares two different surgeries for removing a single kidney stone that is 2 to 3 centimeters in size. One method uses a flexible scope with a suction tube, and the other uses a small incision in the back. The goal is to see which works better and has fewer side effects.
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 trial compares two methods to remove kidney stones that are 2-4 cm in size: one uses a thin tube through a small cut in your back (VISOR), and the other uses a larger cut (PCNL). The goal is to see which approach works better and has fewer side effects.
