Improvements in ureteroscopes have led to improved stone free rates. Two new devices (FANS - Flexible and Navigable Suction) and the CVAC ureteroscope have never been compared head to head. This trial will compare these two new suction ureteroscope technologies against each other
Ureteroscopy (URS) is recommended by the American Urological Association for surgical treatment of kidney stones \< 2 cm in linear dimension. Although historically shock wave lithotripsy was the most common surgical treatment, since 2013 ureteroscopy has become the most common surgical treatment for kidney stones. There have been great advancements to ureteroscopic technology with improvements in laser technology leading to more efficient and complete stone ablation/ fragmentation. However, stone free rates were still suboptimal, with some series reporting stone free rates of 55% after URS. Ho…
