Summary

This study tested whether a silicone stent (Imajin) causes less pain than standard non-silicone stents after kidney stone surgery. 224 adults with kidney or ureteral stones were randomly assigned to receive one of the two stents. Researchers measured pain intensity and how much pain interfered with daily life using surveys taken before surgery and about a week after.
