Compare Trans-Stomal Bladder Lithotripsy Methods in Continent Catheterizable Urinary Reservoirs
Official title: Comparison of Trans-Stomial Bladder Lithotripsy Using Mini-Percutaneous Equipment Versus Trans-stomial Bladder Lithotripsy Using Flexible Fibroscope, Percutaneous Approach and Open Cystolithotomy in Patients With Continent Catheterizable Urinary Reservoir
Run by Hospices Civils de Lyon · NCT07643454 · Data updated 2026-11-12
This study looks at different ways to break up bladder stones in people with continent catheterizable urinary diversions to see which method works best when the normal route isn’t available.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older with a continent catheterizable urinary diversion and a history of relevant cystolitholapaxy or lithotripsy via the continent stoma between 2015 and 2024.
✕Probably not a fit
Patients whose stones do not respond to a chosen lithotripsy method or those with complications unrelated to the procedure may not benefit.

What this trial studies
This observational study compares trans-stomal bladder lithotripsy techniques using mini-percutaneous equipment, flexible fibroscope, percutaneous approaches, and open cystolithotomy in adults with continent catheterizable urinary reservoirs. It collects patient-reported outcomes via QoL-DUCC and Qualiveen questionnaires to gauge impact on quality of life and function. Eligible participants include adults with a history of relevant lithotripsy or endoscopic procedures through the continent stoma between 2015 and 2024. Sites are in Lyon, France, led by Hospices Civils de Lyon with two hospital locations. The study aims to document real-world practice patterns, safety, and patient-perceived outcomes to inform future recommendations.
Why it matters
Potential benefit: If successful, patients may experience safer, more effective stone management with improved quality of life.
How similar studies have gone: Prior reports describe multiple techniques and no single preferred approach, indicating variability and need for comparative data; this study adds observational insight rather than definitive efficacy evidence.
