New hope for kidney stone patients: safer pain relief after surgery?

NCT ID NCT05100017

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

Summary

This study compares two drugs—methocarbamol and oxybutynin—to see which works better for pain and discomfort caused by a ureteral stent placed after kidney stone surgery. About 126 adults aged 18 to 80 who have the surgery will take one of the study drugs along with standard pain medicines. The goal is to find a treatment with fewer side effects that still effectively eases stent-related symptoms.
