Buffered lidocaine eases prostate biopsy pain in new study
NCT ID NCT06661902
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether buffered lidocaine (lidocaine mixed with baking soda) reduces pain during prostate biopsy. 350 men undergoing a prostate biopsy received either buffered or standard lidocaine. Researchers measured pain from the numbing injection and from the biopsy itself using a 0-10 scale.
