Found insideA practical manual on the treatment of pelvic pain, focusing on the many gynecological and non-gynecological causes of the condition. Pudendal nerve block does not abolish sensation to the anterior part of the perineum, as the perineum is supplied by branches of the ilioinguinal and genitofemoral nerves.

The pudendal nerve consists of three ventral rami from S2-S4 of the sacral plexus that converge to form the nerve adjacent to the lateral wall of the pelvic cavity. [6]: 8, Inside the pudendal canal, the nerve divides into branches, first giving off the inferior rectal nerve, then the perineal nerve, before continuing as the dorsal nerve of the penis (in males) or the dorsal nerve of the clitoris (in females). If your doctor can confirm that pudendal nerve entrapment is what’s causing your pain, surgical decompression is the preferred treatment. Pudendal nerve entrapment syndrome is an unusual condition which arises from compression of the pudendal nerve (S2) and causes chronic pain in the saddle sites: the perineal, perianal and genital areas. Pudendal nerve compression based on anatomy: The pudendal nerve entrapment syndromes subdivide into four types based on the level of compression. The function of the sacral plexus is to provide sensory and motor nerve innervation to the pelvis, genitals, thighs, calves, feet, and buttocks.

Feel free to contact me, Dr. Jason Attaman, to discuss treatment options. The Pudendal Nerve. Anatomy of the pudendal nerve. It innervates the external urethral sphincter, providing voluntary control over micturition. It does not carry parasympathetic fibers but does carry sympathetic fibers. [15] (Clarification: Unlike the internal sphincter muscle, the external sphincter is made of skeletal muscle, therefore it is under voluntary control of the somatic nervous system. The pudendal nerve emerges from the S2, S3, and S4 roots’ ventral rami of the sacral plexus. Targeting of the pudendal nerve for diagnostic or therapeutic injection at the ischial spine by using an elec-trodiagnostic technique,32 C-arm fluoroscopy,1,9 and CT scanning has been described.7,21,43 Diagnosis has also re-lied on pudendal nerve latency testing,2 but imaging has played very little role in diagnosis. Research, pioneered by Dr. Stanley Antolak, supports a link between interstitial cystitis (IC) and pudendal neuralgia (PN), a painful nerve inflammation. This means that during periods of increased acetylcholine release the skeletal muscle in the external urethral sphincter contracts, causing urinary retention.

The ischial spine, an easily identifiable structure on CT, is used as the level of injection. The pudendal nerve is a sensory and motor nerve arising from the sacral plexus and forms from spinal nerve roots S2-S4. There are slight differences in the nerve branches for each person but typically there are three branches of the nerve on each side of the body; a rectal branch, a perineal branch and a clitoral/penile branch. (Simply, the spinal nerves exit the spinal column and split at the S2, S3, and S4 vertebra to form the sacral plexus, the nerves which provided motor and sensory nerves for the posterior or back of the thigh, most of the lower leg, and foot, and part of the pelvis.
