Supine vs. Prone Surgery Position for Large Kidney Stones
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This trial compares two surgical positions—lying on your back (supine) versus lying face-down (prone)—during a minimally invasive kidney stone removal procedure called PCNL. The study aims to find which position leads to better outcomes and fewer complications for patients with large kidney stones.
Summary written for real people, not researchers, by Clin2.

This trial compares how lying on your stomach versus your back during kidney stone removal affects blood flow and heart function. It may help doctors choose the safest position for you.
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 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 tests different ways to manage pain after a kidney stone removal procedure called percutaneous nephrolithotomy (PCNL). It aims to find which method works best to keep you comfortable with fewer side effects.
This study compares two positions (lying on your back vs. on your stomach) for a surgery called PNL (percutaneous nephrolithotomy) to remove kidney stones in children. It aims to find which position is safer and more comfortable for kids.
This trial tests if lying on your side vs. on your back during a scope procedure to remove lower kidney stones smaller than 2 cm is better or safer. The goal is to find which position leads to fewer complications and more complete stone removal.
