Summary

This prospective single-arm interventional study evaluated the efficacy and safety of flexible ureteroscopy for the treatment of large renal stones measuring 2 cm or more in pediatric patients. All enrolled participants underwent flexible ureteroscopic stone disintegration using a single-use flexible ureteroscope and Holmium laser lithotripsy. The study was designed to assess whether this minimally invasive approach could provide effective stone clearance with acceptable perioperative safety in children with large renal stones.

PROCEDURE

Flexible Ureteroscopic Stone Disintegration

Flexible ureteroscopy was performed using a 7.5-Fr single-use flexible ureteroscope. Renal stones were fragmented with a Holmium:YAG laser. A ureteral access sheath was used when feasible, and a double-J ureteral stent was placed at the end of the procedure.
