New study seeks better way to remove bladder stones in kids
NCT ID NCT07614880
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two surgical techniques for removing bladder stones in children aged 2 to 14 years. One method uses a small cut in the belly area with a vacuum to remove stone fragments, while the other uses a scope through the urethra. The goal is to see which approach is faster and has fewer side effects like pain, bleeding, or infection.
