Battle of the scopes: which stone removal method wins?

This study looked at 100 adults with large upper ureteric stones (over 10 mm) to compare two surgical techniques: one going down from the kidney (antegrade) and one going up from the bladder (retrograde). The goal was to see which method removes stones more completely and safely, and which leads to a shorter hospital stay. Both approaches are already used, but this study directly compares them to help doctors choose the best option.
