Summary

This study compared two common surgeries for removing large kidney stones stuck in the upper ureter: ureteroscopic lithotripsy (URS) and laparoscopic ureterolithotomy (LU). Fifty-six adults with a single stone between 10-20 mm were randomly assigned to one procedure. Researchers measured operation time, hospital stay, pain, complications, and how completely stones were removed after four weeks to determine which method is safer and more effective.
