Retrograde access study for kidney stone removal
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study compares two ways of getting a needle to the kidney for PCNL surgery (a procedure to remove stones). It aims to find which approach is safer and more effective for people with kidney stones between 1.5 and 3 cm.

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 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.
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 ways of positioning patients during surgery to remove large kidney stones. It aims to find which position is safer and more effective for people with stones larger than 2 cm.
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.
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.
