Laser treatment for upper ureter stones: a study
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study compares a flexible type of ureteroscopy with laser to break up stones in the upper ureter. It may help people with a single stone up to 2 cm avoid a more invasive surgery.
Summary written for real people, not researchers, by Clin2.

This trial tests a supplement called Neorenal Forte to help clear tiny leftover kidney stone pieces after laser surgery. If you have small fragments left after your procedure, this study may help you get rid of them.
This trial compares two different lasers used to break up kidney stones during a procedure called flexible ureteroscopy. It may help determine which laser works better and is safer.
This trial compares two types of lasers used to break up kidney and ureter stones during a ureteroscopy procedure. The goal is to see which laser works better at breaking stones into smaller pieces.
This study compares two types of lasers (a new super-pulsed thulium fiber laser vs. the standard holmium laser) used during a scope procedure to break up kidney and upper ureter stones. If you have stones between 10 and 25 mm and are scheduled for ureteroscopic surgery, this trial may help determine which laser works better.
This trial tests a new device that combines a laser and a suction sheath to break up and remove kidney or ureter stones. It may help people with stones between 6mm and 20mm who are scheduled for a specific type of stone surgery.
This study compares two types of laser treatments used during a minimally invasive procedure to break up kidney stones. You would be randomly assigned to receive one of the two lasers to help doctors understand which works better for stone removal.
