Stent Related Symptoms Defined by Ureteral Stent Symptom Questionnaire in Patients With Image-Informed Ureteral Stent Lengths
Weill Medical College of Cornell University
Summary
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.

Interventions
- DeviceVariable length ureteral stent
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.
- DeviceImage-informed length ureteral stent
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.
