New inhaler may ease pain during male urology procedures
NCT ID NCT07192198
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether breathing in a pain-relief medicine called Penthrox (methoxyflurane) can help reduce pain and anxiety during urologic procedures done with local anesthetic. Forty adult men having procedures like hydrocelectomy or testicular biopsy took part. The goal was to see if adding Penthrox improves comfort compared to local anesthetic alone.
