The pudendal nerve, a crucial component of the peripheral nervous system, originates from the sacral plexus and plays a vital role in sensation and motor function of the perineum, external genitalia, and anal sphincter. Its complex innervation makes it highly relevant in medical fields such as urology, gynecology, and proctology, often implicated in chronic pain conditions and functional disorders.
In medical and ultrasound diagnostics, the pudendal nerve can be targeted for nerve blocks, neuromodulation, or imaging to identify entrapment or injury. High-resolution ultrasound provides a non-invasive method for visualizing the nerve’s anatomy and pathology, aiding in the accurate diagnosis and treatment of pudendal neuralgia and related conditions, thereby improving patient outcomes.
