Comparing two types of ureteral access sheaths for kidney stone surgery
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This trial compares a vacuum-assisted ureteral access sheath to a standard one during kidney stone surgery (retrograde intrarenal surgery). The goal is to see which might work better and be safer for patients.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 84 years old.
- You need kidney stone surgery that uses a ureteral access sheath (size 11 to 13 French).
- You do not have a urinary tract infection (urine must be sterile before surgery).
- Your kidneys have a normal shape (no anatomical issues).
- You have two functional kidneys (not a single kidney).

This trial compares two different tubes used during surgery to remove kidney stones. The goal is to see if one type works better than the other for clearing stones safely.
This trial tests different types of tubes (called ureteral access sheaths) used during a minimally invasive kidney stone removal procedure called RIRS. The goal is to see which type works best and causes the least damage to your ureter (the tube that carries urine from your kidney).
This trial compares two ways of removing kidney stones during a procedure called flexible ureteroscopy. One method uses a special sheath that helps suction out stone fragments, which may improve stone removal and recovery.
This study compares a standard kidney stone removal procedure (ureteroscopy with laser) to a newer suction-based technology. If you have a kidney stone that needs surgery, this trial may help your doctor find the best way to remove it.
This trial compares two methods used during surgery to treat kidney stones. It looks at whether one type of tube (a fan-shaped access sheath) causes less kidney injury after surgery than the standard tube. This could help patients have a safer recovery.
This study compares two methods used during surgery to remove kidney stones. It will see if a new device is as safe and effective as the standard one for breaking up and removing stones.
