NCT ID NCT04993859
First seen Jun 24, 2026 · Last updated Sep 10, 2026 · Updated 3 times
Summary
This study looks at how two common chemotherapy drugs, vincristine and doxorubicin, affect bladder function and urine composition in children who have finished cancer treatment. Researchers will use simple, non-invasive tests to measure urine flow and check for bladder-related proteins. The goal is to better understand and detect bladder problems early in childhood cancer survivors.
