Is this trial a fit for you?

Likely a good fit

Pediatric patients with a renal stone burden of 1 to 2.5 cm and no contraindicating infections, coagulation disorders, or anatomical factors precluding either procedure.

Probably not a fit

Patients with stones outside the 1–2.5 cm range, active untreated infection, uncorrected coagulopathy, or anatomy that prevents either procedure may not benefit.

What this trial studies

The trial compares two surgical approaches for pediatric renal stones up to 2.5 cm: flexible ureteroscopy with a navigable suction ureteral access sheath versus mini-percutaneous nephrolithotomy with a vacuum-assisted access sheath. It will look at safety and effectiveness, including stone clearance, operative factors, and complication rates. Eligible participants are children with imaging-confirmed stones and no contraindicating conditions. The investigation aims to determine if suction-assisted techniques improve outcomes in pediatric stone management across these two commonly used procedures.

Why it matters

Potential benefit: If successful, suction-assisted flexible ureteroscopy could offer safer and more effective stone clearance with fewer complications in children.

How similar studies have gone: Preliminary data in adults and select pediatric series suggest suction-assisted approaches may improve visibility, reduce operative time, and increase stone clearance, but pediatric evidence remains limited.
