Comparing two procedures for large kidney stones
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study compares two ways to remove large staghorn kidney stones: one uses a thin scope through the urinary tract, the other uses a small cut in the back to reach the kidney directly. The goal is to see which method is safer and works better for patients.
Summary written for real people, not researchers, by Clin2.

This study tests a new way to remove large, branching kidney stones (staghorn stones) using two types of scopes through the back and urinary tract. It aims to see if this method is safe and effective, possibly leading to better stone removal with less harm.
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 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 ways to remove kidney stones that are medium to large in size. It will help find out which method works better and is safer for patients.
This study tests a newer, less invasive way to remove large kidney stones (partial staghorn stones) using a flexible tube and a tiny needle. It aims to see if this method is safer and more effective than standard surgery, helping you recover faster.
