Which disposable scope is best for kidney stones? new trial aims to find out
NCT ID NCT07360353
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares three different single-use flexible ureteroscopes used to remove kidney stones. Researchers will look at cost, how long the surgery takes, complications, and how well the stones are cleared. About 180 adults with small-to-medium kidney stones will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Single-use flexible ureteroscopes (LithoVue, WiScope, Scivita)
- What this could lead to
- If successful, this study could identify the most cost-effective and safest single-use ureteroscope for kidney stone surgery, potentially improving patient outcomes and reducing healthcare costs.
- What could go wrong
- This is a relatively small, early-stage comparative device study, not a large phase 3 trial. Results may not apply to all patients or settings, and differences between scopes might be minor.
