The sympathetic levels of the urinary bladder are typically:

Explanation:
Sympathetic input to the bladder comes from the thoracolumbar spinal cord, specifically the segments around T11 to L2. These preganglionic fibers travel through the hypogastric nerves and pelvic plexus to reach the bladder, where they help store urine. They do this by relaxing the detrusor muscle and tightening the internal urethral sphincter, preventing voiding. That makes T11–L2 the most accurate range for bladder sympathetic innervation. The other ranges either lie outside this thoracolumbar zone or don’t align with the standard pathway to the bladder, so they don’t fit as well.
