Summary

This study looked at 130 people treated for ureteral stones using two different sizes of ureteroscopes. Researchers measured how well each scope worked and how much stress the surgeon felt before and after the procedure. The goal is to find out if using a smaller or larger scope can improve success and reduce surgeon anxiety.
