Using a flexible suction sheath with flexible ureteroscopy for lower-pole 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

The trial will enroll adult patients with lower calyceal (lower-pole) kidney stones who are scheduled for flexible ureteroscopy (fURS). During the procedure, surgeons will use a flexible, navigable suction ureteral access sheath alongside the fURS to aspirate stone fragments. Key outcomes include postoperative stone-free status, need for secondary interventions, and infectious or bleeding complications; standard exclusions include active urinary infection, coagulopathy, and renal or ureteric anomalies. Procedures and follow-up imaging will be performed at Zagazig University Hospitals to capture procedure success and complications.
