NCT ID NCT07627828

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study compares a new type of ureteral stent (ComfiJ) with a standard Double-J stent in 150 adults who need a short-term stent after kidney stone surgery. The goal is to see if the ComfiJ stent causes fewer urinary symptoms, like pain or urgency, two weeks after surgery. Participants are randomly assigned to receive one of the two stents during their operation.

Active substance

ComfiJ ureteral stent

What this could lead to

If it works, this could lead to a more comfortable stent option for people undergoing kidney stone surgery, reducing pain and urinary symptoms.

What could go wrong

This is a relatively small, early-stage trial with 150 participants, so results may not apply to everyone. The new stent might not be significantly better than the standard one.
