Comparing Four Types of Ureteral Stents After Laser Treatment for Kidney and Ureter Stones

What this Trial Is About

Researchers are conducting a randomized controlled trial to compare postoperative symptoms related to four types of ureteral stents used after ureteroscopy with laser lithotripsy for treating upper urinary tract stones. The study will assess differences in symptom scores among 6Fr Percuflex, 6Fr Tria, 4.8Fr Percuflex, and 4.8Fr Tria ureteral stents. A total of 272 participants will be enrolled and followed for up to approximately 10 weeks. Participants will undergo surgery with placement of one of the four ureteral stents. The trial includes three clinic visits a pre-operative visit, a visit for stent removal 1-2 weeks after surgery, and a postoperative visit 3-6 weeks after surgery. The stents differ in size and coating properties, with the Tria stents designed to soften at body temperature and resist mineral buildup. Researchers will collect data including patient demographics, medical history, and physician assessments. Participants will complete the Ureteral Stent Symptom Questionnaire USSQ twice to measure urinary symptoms, pain, general health, work performance, and sexual matters at stent removal and post-stent removal visits. Additional outcomes include quality of life measured by WisQOL, emergency room visits, unscheduled clinic follow-ups, extra prescriptions for stent symptoms, stent complications by imaging, and physician evaluations. These assessments will help compare the patient experience and safety of each stent type throughout the study period.
