A new flexible endoscope that quickly removes large kidney stones

Breaking the Scope Port Size Barrier: A New Kind of Endoscope that Removes Large Kidney Stones Rapidly

NIH-funded research Endotheia, INC. · NIH-11110725

This study is testing a new flexible tool that can quickly change from a camera used to look inside the body into a suction device that helps remove big kidney stones, making it easier and faster for patients to get treatment without needing major surgery.

What this research studies

This research aims to develop an innovative flexible ureteroscope that can quickly transform from an endoscope into a large-lumen suction catheter. This transformation allows for the rapid removal of large kidney stones, which can significantly reduce the need for invasive surgical procedures. The device is designed to decrease procedure times by at least 36 minutes, making it easier for patients with larger stones to undergo minimally invasive treatments. By utilizing a unique mechanical actuation concept, the device maintains a large central lumen for effective suction and visualization.

Who could benefit from this research

Good fit: Ideal candidates for this research are patients suffering from large kidney stones who require interventional procedures.

Not a fit: Patients with small kidney stones or those who do not require surgical intervention may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide patients with a faster, less invasive option for removing large kidney stones, reducing recovery time and complications.

How similar studies have performed: Other research has shown promise in developing advanced endoscopic techniques, but this specific approach is innovative and largely untested.
