Clinical Trial Summary

The purpose of this study is to determine how soon ureteral stents can be safely removed following surgery.


Description:

The rationale for this study is to determine if there is a difference in symptoms or complications among patients undergoing uncomplicated ureteroscopy for stone removal with shorter indwelling stent duration. Currently there are only a few small studies exploring the optimal duration of stent placement after stent placement and no multicenter randomized control trials. The investigation aim is to determine if earlier ureteral stent removal will reduce urinary symptoms after stent removal and improve quality of life without increasing risk of negative side effects. Using questionnaires for stent related symptoms the researchers will assess stent indwelling time effect on patient reported side effects.

Outcome

Type Measure Description Time frame Safety issue
Primary Change in Urinary Symptom Scores The urinary symptoms will be assessed using the self-reported Canadian Endourology Group Stent Symptom Score. Seven item questionnaire to assess urinary stent symptoms using a 5-point Likert scale; higher score indicated worse outcome. Post-operative day 2-3 and 2-3 days after stent removal
Secondary Change in Pain Scores Pain score as indicated in the self-reported Canadian Endourology Group Stent Symptom Score questionnaire with a scale of 0-10 (10 being the worst) Post-operative day 2-3 and 2-3 days after stent removal
Secondary Change in Quality of life Change as calculated using the Wisconsin "Living With Kidney Stones" Questionnaire, which is a validated document assessing the quality of life of kidney stone patients. Likert scale 1-5 on 28 items total score range 28-140, with a lower score being associated with a lower quality of life. Post-operative day 2-3 and 2-3 days after stent removal
Secondary Return to work Number of days participants return to work 30 days
Secondary Complications Number of subjects to experience complications assessed by telephone, epic messages, ER visits related to procedure, unanticipated provider visits, and hospitalizations. 30 days
