A superior hypogastric plexus block (also known as a hypogastric block) is an advanced, minimally invasive procedure used to treat pelvic and genital pain that has been so far unresponsive to oral medications and other conventional treatments. This injection is considered to be a sophisticated, and more precise version of a sympathetic block that targets a specific region of the Sympathetic Nervous System (SNS) known as the Superior Hypogastric Plexus.
This injection can be used to control pelvic pain that cannot be controlled by oral medication. Also if the side effects of pelvic pain medications, such as excessive nausea, constipation, and sedation are too strong for the patient. This blockade contains sympathetic fibers efferent to pain fibers afferent to the bladder, urethra, uterus, vagina, vulva, perineum, prostate, penis, rectum and descending colon, so it can alleviate pain originating from the above mentioned regions. Its effectiveness is proven.
