Aspirating vs non-aspirating ureteral access sheath in RIRS for kidney stones

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective, randomized study compares two ureteral access sheath technologies used during retrograde intrarenal surgery for kidney stones under 2 cm. Participants are 18 to 75 years old and are assigned to either an aspirating or non-aspirating sheath, with standardized surgical technique. Primary outcome is stone-free rate after surgery; secondary outcomes include operative and fluoroscopy times, hospital stay, Clavien-Dindo complications, infection-related parameters, and need for ureteral stenting. Demographic, stone, and perioperative data will be collected with follow-up assessments to determine stone clearance and safety. The study aims to clarify whether suction-assisted sheaths offer meaningful advantages over conventional devices.
