What this trial studies

This randomized Phase 3 trial enrolls adults aged 19–80 who receive a unilateral ureteric stent after rigid ureteroscopy or retrograde intrarenal surgery and assigns them to tamsulosin 0.4 mg, solifenacin 5 mg, or mirabegron 25 mg. Symptom burden is measured using the validated Ureteral Stent Symptom Questionnaire (USSQ) on days 1, 7, and 14 after stent placement. Key exclusions include concurrent use of alpha-blockers or anticholinergics, neurogenic bladder or OAB, active febrile UTI, single kidney, recent major pelvic or bladder surgery, pregnancy/breastfeeding, and significant cardiac or hepatic disease. The trial compares USSQ scores across the three medication arms to determine which drug provides the most symptom relief.

Who should consider this trial

Good fit: Adults aged 19–80 who undergo unilateral rigid ureteroscopy or RIRS with planned ureteric stent insertion and who are not taking excluded medications or having excluded medical conditions are ideal candidates.

Not a fit: Patients with neurogenic bladder or OAB, a single kidney, active febrile UTI, pregnancy or breastfeeding, major cardiac/hepatic disease, recent pelvic/bladder/prostate surgery, or those undergoing percutaneous or open ureteric surgery are excluded and unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, one of these medications could meaningfully reduce pain and urinary bother from ureteral stents, improving recovery and quality of life after stone surgery.

How similar studies have performed: Previous randomized studies and meta-analyses have shown modest benefit from alpha-blockers and antimuscarinics for stent-related symptoms, while mirabegron has been less extensively studied for this indication.
