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.\n\nBoth 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.",[84],"Pediatric Renal Stones","2026-08-10",{"date":87,"type":88},"2026-08-13","ACTUAL",{"date":90,"type":88},"2026-06-01",{"date":92,"type":78},"2027-06-10",{"name":5,"class":6},1]
