What are the sympathetic levels of the lower ureters?

Explanation:
The lower ureter receives sympathetic input via the lumbar and pelvic plexuses, with fibers traveling from the spinal levels that supply the abdominal and pelvic viscera. Specifically, the lower ureter gets sympathetic fibers from the least splanchnic nerve (around T12) and from L1 through the inferior hypogastric plexus, giving a spinal level range of T12–L1. This combination explains why referred pain and autonomic effects related to the lower ureter align with those segments. The other ranges either miss the T12 contribution or sit at levels too high or unrelated to the pelvic portion, so they don’t match the actual innervation pattern.
