Summary

This study is testing a new type of ureteral stent that is designed to slowly dissolve and pass out of the body on its own after being placed during kidney stone surgery. The goal is to see if it safely drains urine and breaks down within 90 days, so patients don't need a second procedure to remove it. About 87 adults who had a straightforward stone removal will be followed for three months to check for complications and how well the stent works.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Uriprene® Degradable Temporary Ureteral Stent
What this could lead to: If it works, this could offer a safer, more convenient option for patients needing a temporary stent after kidney stone surgery, eliminating the need for a second procedure to remove it.
What could go wrong: This is an early-stage, non-randomized trial with only 87 participants, so results may not apply to everyone. The stent might not degrade as expected or could cause side effects like pain or infection.
