Sponsor's own description
This randomized controlled trial aims to compare the efficacy and safety of two suction techniques during retrograde flexible ureteroscopy (FURS) for lower calyceal renal stones measuring 1.5-2 cm. The study evaluates Flexible \& Navigable Suction Ureteral Access Sheath (FANS) versus Antegrade Suction (via percutaneous access) in improving stone-free rates (SFR), reducing operative time, and minimizing complications such as bleeding, ureteral injury, and infection. A total of 120 adult patients will be randomized into two groups, undergoing either flexible ureteroscopy (FURS) with Flexible \& Navigable Suction Ureteral Access Sheath (FANS) or flexible ureteroscopy (FURS) with antegrade suction, at Banha University Faculty of Medicine.
