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

2026年7月29日 更新者：Weill Medical College of Cornell University
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.

武器和干预

参与者组/臂
干预/治疗
有源比较器：Variable length ureteral stent
设备：Variable 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.
实验性的：Image-informed length ureteral stent
设备：Image-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.

主要结果指标

结果测量
措施说明
大体时间
Differences in scores as measured by the USSQ between the two treatment arms.
大体时间：5 hours post-surgery
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.
