Anatomical review outlines neural innervation of the bladder and sphincter apparatus in human pelvic anatomy, highlighting surgical targets for vesical disorders.

Key Points

To delineate the neural pathways supplying the bladder and evaluate potential neurosurgical targets for managing vesical conditions.
Examined the autonomic and somatic nerve pathways supplying the bladder, sphincter apparatus, and posterior urethra.
Characterized the anatomical course and fiber composition of the thoracicolumbar outflow and presacral nerve.
Identified three nerve networks innervating the bladder: sympathetic (thoracicolumbar outflow), parasympathetic (sacral outflow), and somatic (pudic nerves).
Demonstrated that the thoracicolumbar pathway converges into the presacral nerve (superior hypogastric plexus), situated beneath the peritoneum anterior to the last lumbar vertebra.
Observed that over half of the axons in the presacral nerve are medullated preganglionic fibers arising from lumbar sympathetic ganglions.
