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.

Placement of variable length ureteral stent at the end of ureteroscopy. The variable length stent is a one-size-fits-all stent that measures 22-30cm.
Placement of image-informed length ureteral stent at the end of ureteroscopy. The length will be 22cm, 24cm, or 26cm depending on the distance of the renal vein to ureterovesical junction on imaging.

Differences in scores as measured by the USSQ between the two treatment arms.
The Ureteral Stent Symptom Questionnaire (USSQ) is a validated 38-item questionnaire used to evaluate the impact of ureteral stents on a participant's quality of life. Scores will be reported for the following domains: urinary symptoms, pain, general health, work performance, and sexual matters. The range of scores for each domain are, respectively, 6-57, 6-37, 6-30, 3-15, and 0-10. In each domain, a higher score represents worse quality of life and lower score represents better quality of life.
Time frame: 5 hours post-surgery

Difference in the rate of adverse events between the two treatment arms.
Adverse events include but are not limited to early stent removal due to stent-related symptoms, stent migration, and failure of stent insertion.
Time frame: From enrollment until 30 days after end of treatment, an average of 5 weeks.
