Etiology of genitourinary tract crisis

  Genitourinary crisis is one of the symptoms of spinal syphilis, and visceral crisis includes genitourinary crisis. Spinal syphilis (myelosyphilis) is an important type of central nervous syphilis that includes spinal consumption (tabesdorsalis), spinalmeningovascular syphilis, and syphilitic myelitis. Syphilitic meningomyelitis is also called syphilitic meningomyelitis because the lesions often involve the spinal membrane.  I. Pathogenesis Syphilis is caused by a slender, spiral-shaped, mobile microorganism, namely the pale spirochete infection. The dense spirochete often enters the central nervous system 3 to 18 months after infection of the body. If the cerebrospinal fluid examination is completely negative after 2 years of infection, the chance of having central syphilis is 1/20; if the cerebrospinal fluid examination is completely negative after 5 years of infection, the chance is reduced to 1/100. The central infection of syphilis begins with syphilitic meningitis (about 1/4 of the total syphilis infection), a large part of which is asymptomatic meningitis, which can only be detected by lumbar puncture, and a small part The more severe meningitis that manifests as predominantly cerebral nerve palsy, epilepsy, and increased intracranial pressure. Syphilitic meningitis can go through an asymptomatic phase for several years and eventually enter the brain or spinal cord parenchymal involvement phase, which includes meningeal vascular syphilis, paralytic dementia, spinal cord consumption, and syphilitic spinal myelitis.  The posterior roots of the spinal cord, especially the posterior roots of the lumbosacral segment, become significantly thinner and greyer, and the spinal cord itself becomes thinner due to the degeneration of the posterior columns of the spinal cord, and only a few neurons in the dorsal root ganglia are seen.  2, syphilis spinal myelitis dural inflammatory thickening, and adhesions with the arachnoid membrane, soft spinal membrane, and then cause damage to the spinal cord supply vessels and nerve roots resulting in spinal cord degeneration, the appearance of spinal cord long bundle victimization signs.  3, the spinal membrane vascular syphilis is subacute or acute transverse spinal cord damage, microscopically can be seen endovascular inflammation, perivascular inflammatory cell exudation and spinal infiltration, the spinal cord myelin sheath and axon are degenerative.
