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.

| 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. | 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. | From enrollment until 30 days after end of treatment, an average of 5 weeks. |

| Image-informed length ureteral stent | Device | 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. |
