Stone Clearance With Aspiration vs Other Technologies: a Real-world Evidence Study

The goal of this clinical trial is to evaluate the effectiveness and safety of Steerable Ureteroscopic Renal Evacuation (SURE) with the CVAC System versus other commonly used renal-stone interventions.

A Comparative Study Between the Usage of Flexible and Navigable Suction Ureteral Access Sheath Versus Traditional Access Sheath in Retrograde Intrarenal Surgeries

A comparative study between the Usage of Flexible and Navigable Suction Ureteral Access Sheath (FANS) versus Traditional Access sheath in RIRS : Randomized controlled trial .

Trial of Ureteroscopy vs Steerable Continuous Flow Aspiration Technology

The goal of this clinical trial is to compare Steerable Ureteroscopic Renal Evacuation (SURE) using the CVAC System and standard ureteroscopy (URS) with laser lithotripsy for the treatment of urolithiasis. This is a prospective, randomized (1:1), multi-center study.

Impact of Surgical Position on Stone-Free Rates in Retrograde Intrarenal Surgery

The goal of this clinical trial is to determine whether the surgical position during retrograde intrarenal surgery (RIRS) affects stone-free rates in adults with kidney stones. The main questions it aims to answer are: * Does the modified lithotomy position result in a higher stone-free rate compared to the standard lithotomy position? * Are there differences in complication rates between the two surgical positions? Researchers will compare patients undergoing RIRS in the standard lithotomy position to those in the modified lithotomy position (30-degree Trendelenburg with elevated surgical side) to assess its impact on stone clearance and surgical outcomes. Participants will: * Be randomly assigned to one of two surgical positions * Undergo RIRS with standard surgical procedures * Have follow-up imaging to assess stone clearance after surgery This study aims to improve surgical techniques and patient outcomes in kidney stone treatment.

Intra-ureteric Aminophylline Instillation on Flexible Ureteroscopy Procedure

in this study we are going to evaluate the efficacy of intra-ureteric aminophylline instillation in facilitating ureteric access sheath placement prior to flexible ureteroscopy in reducing ureteric injury rates.
