High-dose dexamethasone to relieve ureteral stent symptoms after kidney stone procedure
Official title: Dexamethasone for Ureteral STent Symptoms (DUSTS): A Randomized, Double-blinded Controlled Study
Run by The Methodist Hospital Research Institute · NCT06930690 · Data updated 2026-11-12
In people undergoing ureteroscopy with a ureteral stent, the study tests whether a 20 mg dose of dexamethasone helps reduce urinary symptoms and pain more than a 4 mg dose.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–70 undergoing unilateral retrograde ureteroscopy with planned ureteral stent placement for renal/ureteral stones.
✕Probably not a fit
Patients with uncontrolled diabetes, immune suppression, or other exclusions may not benefit and could be at higher risk from high-dose steroids.

What this trial studies
This interventional study compares two doses of dexamethasone given at the time of surgery for patients receiving a ureteral stent after ureteroscopy for kidney stones. Participants are randomized to receive either 20 mg or 4 mg of dexamethasone, and they complete questionnaires on postoperative days 1 and 2, plus a one-week medication diary. Follow-up visits occur around day 2 and days 4–7 after surgery, with a total study duration of about 30 days. The primary aim is to see if the higher dose improves quality of life by day 2 and reduces urinary symptoms and pain.
Why it matters
Potential benefit: If successful, the higher dexamethasone dose could lessen postoperative urinary discomfort and pain for patients with ureteral stents.
How similar studies have gone: Previous studies in similar surgical settings have shown mixed results; this trial tests a higher dose specifically for ureteral stent-related symptoms.
