Ureteric plexus
The ureteric plexus is a nerve plexus covering and innervating the ureter. The plexus can be graduated into three parts, as the ureter itself can be divided: In the upper part of the ureter, the plexus gets its nerve fibers mainly from the renal plexus, but also from the abdominal aortic plexus. In the intermediate part the plexus receives nervous input from the superior hypogastric plexus and in the lower part from the inferior hypogastric plexus.
The plexus contains both sympathetic and parasympathetic fibers, where the sympathetic components come from T11 to L2 levels of the spinal cord. Preganglionic vagal fibers run through the celiac plexus and reach the ureteric plexus.
