Comparing two types of single-use ureteroscopes for kidney stones in children
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This trial compares two types of disposable flexible ureteroscopes to see which works better for removing kidney stones in children. If your child has a single kidney stone or multiple stones that add up to less than 20 mm, this study may help guide better treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your child is scheduled for ureteroscopy (a tube-like scope through the urinary tract) to treat a kidney stone
- The kidney stone(s) must be between 5 mm and 20 mm in total size
- Your child is under 14 years old
- If your child is under 8, a parent must sign the consent form; if 8 or older, both parent and child must sign
- Your child does not have an uncontrolled urinary tract infection or a bleeding disorder

This trial tests a specific flexible scope (Shenzhen HugeMed 6.3 French) for removing kidney or ureter stones. It looks at how well it works, costs, and recovery, and may be a good option if you have stones smaller than 2.5 cm and need your first such surgery.
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.
This study compares two types of ureteral access sheaths used during flexible ureterorenoscopy, a minimally invasive procedure to remove kidney stones smaller than 2 cm in children. The goal is to see which tool works better and is safer for your child.
This study compares two sizes of flexible ureteroscopes (small tubes used to remove kidney stones) to see if a thinner one is just as safe and effective as a slightly thicker one. You might join if you're having a ureteroscopy for small kidney stones.
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.
