ClinConnect Summary

This clinical trial is looking at how two types of stents, which are small tubes placed in the urinary tract, affect children undergoing surgery for kidney stones. One type of stent is designed to prevent reflux, which is when urine flows backward, while the other is a standard stent. The goal is to see if the anti-reflux stents help reduce symptoms and complications better than the standard ones for kids who have kidney stones.

To join the study, children must be under 18 years old and have been diagnosed with kidney stones through a CT scan. Parents must sign a consent form, and older children may also need to sign. The trial is currently recruiting participants, and families can expect to monitor how the stents affect their child's comfort and health during recovery. It's important to know that some children may not be eligible if they have certain health issues, past surgeries, or are taking specific medications that could affect the study results.
