With a herniated lumbar disc compressing the cauda equina nerve, patients may present with manifestations of the perineum, such as numbness in the saddle area. Female patients may also experience acute urinary retention, difficulty urinating, and the suprapubic bladder may bulge significantly. Male patients are prone to sexual dysfunction, making sexual life impossible. Therefore, once the lumbar disc herniation compresses the cauda equina nerve, patients should be diagnosed and treated early. Clinically, surgery is usually considered to completely remove the herniated nucleus pulposus tissue through surgery to release the cauda equina nerve compression and restore the nerve function before the cauda equina nerve becomes degenerative and necrotic, which can enable patients to resume normal urination and sexual life and avoid serious adverse consequences.
