Summary

This trial is testing whether or not a stent inserted after a surgery to remove kidney stones leads to fewer complications than not having a stent.

Who is the study for?
This trial is for adults with nonobstructing kidney stones smaller than 1.5cm in total diameter who are undergoing ureteroscopy. It's not for those under 18, pregnant, planning multiple surgeries, or with certain kidney conditions like a solitary kidney or reduced function (eGFR <60 mL/min).
What is being tested?
The study aims to see if there's a difference in complications when patients receive a stent after ureteroscopy for kidney stones versus not receiving one at all.
What are the potential side effects?
Potential side effects may include discomfort from the stent, urinary symptoms like frequent urination or urgency, blood in urine, and possibly increased risk of infection.
