The superior hypogastric plexus (in older texts, hypogastric plexus or presacral nerve) is a plexus of nerves situated on the vertebral bodies anterior to the bifurcation of the abdominal aorta. It bifurcates to form the left and the right hypogastric nerve.^[1] The SHP is the continuation of the abdominal aortic plexus.^[2]

The superior hypogastric plexus receives contributions from the two lower

From the plexus, sympathetic fibers are carried into the pelvis as two main trunks - the right and left hypogastric nerves - each lying medial to the internal iliac artery and its branches. The right and left hypogastric nerves continues as inferior hypogastric plexus; these hypogastric nerves send sympathetic fibers to the ovarian and ureteric plexuses, which originate within the renal and abdominal aortic sympathetic plexuses.^[2]

The superior hypogastric plexus is often displaced somewhat to the left of the midline. It is situated between the common iliac arteries. It is anterior to the

Presacral neurectomy is a laparoscopic procedure where superior hypogastric plexus is excised, so that the pain pathway is cut off from the spinal column. This procedure is done to manage chronic pelvic pain when conservative medical therapy fails.^[1]
