Botulinum toxin A (Botox) injection into muscles of pelvic floor as a treatment for persistent pelvic pain secondary to pelvic floor muscular spasm: A pilot study

Abstract

Background: Persistent pelvic pain (PPP) remains an important cause of morbidity. Pelvic floor muscle spasm is an important contributor to PPP. Aims: The study’s primary aim was to assess if botulinum toxin (BoNT) injection to pelvic floor muscles altered pain scores or quality of life (QoL) at six, 12 and 26 weeks. Secondary aims included investigating the impact of BoNT on opiate usage, examining the role of pain catastrophising, and assessing for complications. Materials and Methods: A single-centre prospective cohort study enrolled 21 patients with PPP who had failed physiotherapy techniques. Each participant underwent BoNT injection to muscles of the pelvic floor and pudendal nerve bloc..
