Comparing two ways to remove large kidney stones
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study compares two minimally invasive procedures to remove large staghorn kidney stones: one through a small tube in the back (PCNL) and the other through the urinary tract with a flexible scope (ureteroscopy). It helps determine which method is safer and works better.

This study tests a surgery that uses a thin scope through the urethra to help remove large, branched kidney stones (staghorn stones) through a small incision in your back. It aims to safely remove more stones with fewer complications.
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 trial compares two types of surgery for removing large, branching kidney stones called staghorn stones. It will help determine which method is safer and more effective.
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.
This trial compares two ways to remove complex kidney stones through a small cut in the back. It uses a special scope to see inside the kidney, and some patients get one or multiple small tunnels to reach the stones. The goal is to see which method is safer and more effective.
