Summary

This study looks at whether removing a ureteral stent 3 days after kidney stone surgery is as safe and less bothersome than the usual 7 days. About 172 adults having simple stone treatment will be randomly assigned to either 3 or 7 days of stent placement. The goal is to see if a shorter time reduces urinary symptoms and pain without increasing complications.
