Efficacy and Safety of Flexible Ureteroscopy With Flexible Navigable Suction Ureteral Access Sheath Versus Mini-Percutaneous Nephrolithotomy With Vacuum-Assisted Access Sheath

Sponsor: Ain Shams University

Summary

Mini-percutaneous nephrolithotomy (mini-PCNL) and retrograde intrarenal surgery (RIRS) are both effective treatment modalities for renal calculi measuring up to 2.5 cm in pediatric patients, demonstrating similar efficacy and complication profiles. Suction has emerged as a potentially transformative adjunct in both percutaneous nephrolithotomy (PCNL) and RIRS. Recent studies evaluating various suction mechanisms during RIRS and mini-PCNL have demonstrated multiple benefits, including reduced operative time, higher stone-free rates (SFR), decreased intrarenal pressure (IRP) and temperature, as well as enhanced intraoperative visualization. Both FANS-UAS in RIRS and VAAS in Mini-PCNL have shown promising outcomes in the pediatric population. Taken together, these findings suggest that suction-assisted technologies whether in RIRS or Mini-PCNL enhance both efficacy and safety in pediatric stone management.
