pudendal nerve pain
Introduction
Introduction to genital neuralgia It is relatively rare in clinical practice, and patients are often ashamed to state the symptoms here, so fewer patients come to the clinic. The pudendal nerve is from the pudendal plexus. The nerve fibers are composed of the anterior branches of the sacs 2, 3, and 4, and contain many parasympathetic nerve fibers. It is accompanied by the internal pudendal artery, leaving the pelvis from the lower edge of the piriform muscle, and then bypassing the ischial spine to retreat into the pelvic cavity through the ischial hole, and under the levator ani muscle along the outer wall of the ischial anal fossa (the ischial rectal fossa) The perineal tube (also known as the Olcok tube, which consists of the obturator muscle fascia) reaches the perineum, which in the rectum rectum (near the ischial tuberosity) emits the following branches: 1. Perineal nerve (1) shallow branch : The scrotum (labia) and the skin behind the perineum, also known as the scrotum (labia) posterior nerve. (2) Deep branch: distributed to the front of the anal external sphincter and the perineal muscles. 2. Lower rectal nerve: distributed in the external anal sphincter and perineal muscles. 3. Penis (carylia) dorsal nerve: distributed in the skin of the penis (clutch). basic knowledge The proportion of the disease: the incidence rate is about 0.001% -0.002% Susceptible people: no special people Mode of infection: non-infectious Complications: impotence
Cause
Causes of genital nerve dry pain
(1) Causes of the disease
More caused by the tibia itself and lesions in the spinal canal.
(two) pathogenesis
In addition to the pelvic tumor, inflammation, pregnancy and other direct compression of the lower part of the sacral plexus, it is more related to the tibia itself and the lesions in the spinal canal, the latter mostly occurs in the cone and the horse's tail of the spinal cord.
Prevention
Psionic nerve dry pain prevention
There is no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease.
Complication
Pulmonary nerve dry pain complications Complications
Can be complicated by incontinence and impotence.
Symptom
Symptoms of genital nerve dryness Common symptoms Allergic anal reflexes weakened or disappeared Itching men's sexual dysfunction in an emergency after heavy incontinence
1. Paresthesia: In the nerve distribution area, abnormal feelings such as feeling dull, tingling, itching, etc. may occur, and in severe cases, the feeling may be completely disappeared, and abnormal signs such as sensation of the genital sensation may be found during the physical examination.
2. Incontinence: Mainly because of affecting sphincter function, causing incontinence, dysuria or urgency.
3. Sexual dysfunction: It is also a major symptom, and male patients may have impotence when severe.
4. Anal reflexes weaken or disappear.
Examine
Examination of genital nerve dryness
Feasible spine, tibia, lateral X-ray examination, CT and MRI if necessary.
Diagnosis
Diagnosis and differentiation of genital nerve dry pain
1. General diagnosis: According to the characteristics of the above symptoms, there is generally no difficulty.
2. Localization diagnosis: A comprehensive examination should be performed to determine the lesions of the spinal canal, the sacral lesions, and the pressure of the pelvic cavity or the nerve trunk itself is damaged.
3. Due to the cause of the spine or spinal canal: more with low back pain, paraspinal tenderness and cramps, positive neck test, limited lumbar motion and other symptoms.
4. Due to pelvic diseases: more dry symptoms (or plexus symptoms), can be diagnosed by anal or double diagnosis of pelvic conditions; when the horse is positive, it indicates that the inflammation of the waist may be greater; Films should be removed after cleansing enema as appropriate to exclude tumors.
Generally not confused with other diseases.
