NCT ID NCT06719089

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a new biodegradable stent (Hydrustent) that dissolves on its own after being placed in the ureter following kidney stone removal. The goal is to see if it keeps urine flowing safely and reduces the need for a second procedure to remove the stent. About 134 adults will be randomly assigned to get either the new stent or a standard one, and they will be followed for 3 months.
