  • Comparing Treatment of Urolithiasis Between Disposable and Reusable Ureteroscope

    Sorry, not yet accepting patients

    Reusable flexible ureteroscopes are widely used to treat various upper urinary tract diseases including urinary stones. However, they require a long turnover time between procedures because of the sterilization process. Moreover, repeated use of a scope ultimately deteriorates its image quality which leads to a high maintenance cost in the long-term. A disposable digital flexible ureteroscope was released in the United States in January 2016, offering an improved image resolution, new scope performance characteristics with every case, and no need for sterilization and repair. Preliminary data from our center has demonstrated that disposable scopes shorten operative time by 25% compared to reusable fiberoptic scope and are associated with a 2/3 reduction in procedural complication rate. Therefore, treatment with disposable scopes may be more effective for patients and facilitate cost management within the hospital. Here, we propose a three-armed, prospective randomized study, comparing treatment outcomes between disposable digital, reusable fiberoptic, and reusable digital flexible ureteroscopes.
