ClinConnect Summary

This clinical trial is studying the differences in symptoms that patients experience after having different types of ureteral stents placed during surgery to remove kidney stones. There are four types of stents being compared: two different sizes of the Percuflex stent and two different sizes of the Tria stent. The aim is to see if the type of stent used affects how patients feel after the surgery. The trial will involve 272 participants and will last for about 10 weeks.

To be eligible for the trial, participants need to have kidney stones that require endoscopic treatment and stent placement. However, pregnant women, patients with kidney transplants, and those with certain medical conditions will not be included. Participants can expect to be monitored for their symptoms throughout the study period. This trial is currently recruiting and welcomes individuals aged 18 and older who meet the criteria. It’s important to note that this study is focusing on improving patient comfort and understanding the best options for stent placement after kidney stone surgery.
