NCT ID NCT06979583
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether using a smaller ureteral stent (4.8 Fr instead of 7 Fr) reduces pain and discomfort after kidney stone surgery. About 100 adults who need a stent after surgery will be randomly assigned to one of the two sizes. Patients will report their pain daily until the stent is removed (usually 7–14 days). The goal is to see if a smaller stent leads to less pain and fewer calls to the doctor.
