Dexamethasone for Ureteral STent Symptoms (DUSTS)

The purpose of this study to learn if high-dose dexamethasone, a type of long-acting steroid, works to decrease urinary symptoms and pain after ureteroscopy and stent placement for kidney stones. The main question it aims to answer is: 1\) Does high-dose steroid change the quality of life score on day 2 after surgery Researchers will compare high-dose of dexamethasone (20 mg) to a standard dose of dexamethasone (4 mg) to see if a higher dose of the drug will help with urinary symptoms and pain Participants will: 1. randomly receive 20 mg or 4 mg of dexamethasone (20 mg) at the time of surgery 2. fill out a questionnaire day 1 and day 2 after surgery 3. fill out a medication diary for one week after surgery 4. visit the clinic on day 2 after surgery for checkup 5. visit the clinic on day 4-7 after surgery for check up

Stent Related Symptoms Defined by Ureteral Stent Symptom Questionnaire in Patients With Image-Informed Ureteral Stent Lengths

Placement of a ureteral stent at the end of ureteroscopy is commonly performed in endourology. The purpose of this study is to determine whether ureteral stents whose lengths are calibrated to a participant's specific ureteral length based on imaging are better tolerated than one-size-fits-all variable length ureteral stents. The investigators hypothesize that ureteral stent lengths calibrated to the ureteral length of each participant will be better tolerated.

Impact of Ureteral Stent and Sheaths Size on Post-Operative Pain

The purpose of this study is to determine if post-operative stent size impacts stent-related pain and discomfort.
