Quality of life with a modified Double-J ureteral stent

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, randomized, open-label controlled trial at St. Luke's Clinical Hospital in Saint Petersburg comparing a standard Double-J ureteral stent to a modified stent with a thinner distal loop. Forty adults undergoing ureteroscopy or RIRS for kidney or ureteral stones who are not pre-stented will be randomly assigned to one of the two stent types. Postoperative reflux is measured by gravity-filling cystogram and patient symptoms are tracked using the Ureteral Stent Symptom Questionnaire (USSQ) on day 1, day 7, and before stent removal. Outcomes will be compared between groups using nonparametric tests for continuous data and chi-square or Fisher's exact test for categorical data.
