Run by Avvio Medical · NCT06942949 · Data updated 2026-11-12
This study is testing a new system to see if it can safely break down urinary stones into smaller pieces, making it easier for people to pass them and feel less pain.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 21 and older with a single ureteral stone between 5 mm and 10 mm in size.
✕Probably not a fit
Patients with non-calcium based stones, untreated urinary tract infections, or those with certain anatomical or medical conditions may not benefit from this study.

What this trial studies
This study evaluates the safety and effectiveness of the Enhanced Lithotripsy System (ELS) for treating urinary stones. The ELS aims to fragment stones into smaller pieces that can be passed more easily, potentially reducing discomfort during the procedure. Eligible participants, aged 21 and older with a single ureteral stone, will undergo the ELS procedure and be assessed 30 days later using a CT scan to check for stone fragments. Additional outcomes include measuring changes in pain levels, quality of life, and the ability to return to normal activities.
Why it matters
Potential benefit: If successful, this treatment could provide a less painful and more effective option for patients with urinary stones.
How similar studies have gone: Other studies have shown promise with similar lithotripsy techniques, suggesting potential for success with this novel approach.
