Basket use to reposition the stone or compensate for failed access is counted as primary endpoint failure. Technical success requires sheath-tip access to the lower pole calyx with ureteroscope deflection, stone visualisation, laser lithotripsy, and fragment aspiration without adjunctive tools. The primary endpoint tests the proposed advantage of active controlled deflection and stable lower calyx access in steerable FANS. The primary outcome is technical success of FANS navigation into the lower pole renal calyx.
