Stone samples were created to simulate the range of particle sizes produced by \u2018dusting\u2019 a 1\u2010cm calcium oxalate monohydrate stone. The stone mixture was introduced into an open vial at a 30\u00b0 angle in aliquots every 3\u2009min over the course of 30\u2009min, mimicking their gradual production by lasertripsy. This benchtop model focused on the effects of geometry (between FANS access sheath and ureteroscope) and suction, excluding complex fluid flow. An 11\/13\u2010F ClearPetra\u00ae FANS UAS with an indwelling ureteroscope was free to move in the vial and targeted visible stones. The vial was intermittently filled to 40\u2009mL with water and emptied using 200\u2010mmHg suction. The experiment had two arms: (1) a permanently indwelling ureteroscope in the FANS UAS to mimic continuous lasering with aspiration and (2) intermittent withdrawal of the ureteroscope to mimic pausing lasering to clear larger fragments through the empty FANS sheath lumen. Three ureteroscope sizes were used: 9.5\u2010F (Lithovue\u2122), 7.5 F (PUSEN) and 6.3 F (Hugemed). The experiment was performed four times for each ureteroscope.

With indwelling 7.5\u2010F and 6.3\u2010F ureteroscopes, the FANS UAS did not become blocked and completely cleared stones of up to 500\u2009\u03bcm and 2\u2009mm, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Without withdrawing the ureteroscope (potentially allowing continuous lasertripsy), it is possible to continuously aspirate small fragments alongside a 7.5\u2010F and a 6.3\u2010F ureteroscope in an 11\/13\u2010F FANS UAS.
