Interventions
placement of flexible and navigable suction sheath (FANS)which has an oblique side branch with pressure vent, that can be connected to negative pressure aspiration, and a flexible tip, allowing for efficient and effective treatment of urinary stones. * Flexible URS diameter will be at the least 2 Fr smaller than the sheath. * The main tube is closed by a rubber seal with a center aperture as the flexible ureteroscope pathway, The oblique tube with a pressure-regulating venting slit along the longitudinal axis acts as a suctioning channel connected to a vacuum device. * The inflow of irrigation is through the endoscope, the outflow of irrigation is between the scope and the sheath. * A vortex is created at the distal end of the sheath, the irrigation fluid, the stone fragments, dust, and blood, etc. in the vortex can be aspirated out. * The aspiration pressure can be adjusted by the pressure vent on the oblique side branch of the sheath.
