A herniated lumbar disc compressing the cauda equina is often caused by a central type of lumbar disc herniation, which can have symptoms of compression of the cauda equina, including the following: 1. disorders of urination and defecation, which can have incontinence or constipation; 2. local skin sensation numbness and pain in the perineum, and men can have sexual dysfunction. Lumbar disc compression of the cauda equina nerve requires early diagnosis and early examination of lumbar spine CT as well as MRI. If the symptoms are not relieved by conservative treatment for two months, or if the symptoms of persistent diaphoresis worsen, surgery should be considered. In the case of acute lumbar disc herniation compressing the cauda equina nerve and causing acute dysfunction, emergency surgery is often required.
