N2  - Introduction Flexible ureteroscopy has advanced modern
stone management; however, lower pole renal stones
remain a challenge due to suboptimal ureteroscope
deflection and navigation using conventional flexible
and navigable suction ureteral access sheaths (FANS).
The SCULPT trial is designed to assess whether the
novel steerable FANS—which enables active controlled
deflection—can improve the success rate of lower pole
access during flexible ureteroscopy.
