Stent pain study pulled before it started
NCT ID NCT02483793
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study planned to compare two drugs, tamsulosin and oxybutynin, for reducing discomfort from urinary stents in children aged 4 to 18. Families would have recorded pain scores and painkiller use for five days after surgery. However, the trial was withdrawn before enrolling anyone, so no results were obtained.
