Superior hypogastric plexus block is utilized to diagnose and treat sympathetically-mediated visceral pain originating from the pelvic organs. Diagnostic blocks serve to evaluate pelvic and rectal pain syndromes, and are used as a prognostic marker prior to neurolytic blocks of the plexus. Therapeutic blocks, on the other hand, are used to provide a sustained analgesia for persistent pelvic or rectal pain, which has failed to respond to conservative treatment measures, but which has responded favorably to injections with local anesthetic solutions. Destructive lesioning with chemical agents (phenol or ethanol), radiofrequency or thermal ablation may be employed to deliver long-term pain control to patients with intractable pain and those with advanced disease states. The goal of neurolytic superior hypogastric plexus block is to improve pain control at lower dosages of opioid analgesics, and thereby reduce potential side effects arising from them.
