About this trial
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.
