Genitourinary crisis is one of the symptoms of spinal syphilis, and visceral crisis includes genitourinary crisis. Spinal syphilis is an important type of central nervous syphilis and includes spinal consumption, spinal membranous vascular syphilis, and syphilitic myelitis. Syphilitic myelitis is also called syphilitic spinal myelitis because the lesions often involve the spinal membrane. Syphilis is caused by infection with a slender, spiral-shaped, mobile microorganism known as the pale spirochete. The dense spirochete often enters the central nervous system after 3 to 18 months of infection. If the cerebrospinal fluid examination is completely negative after 2 years of infection, the chance of developing 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. Cerebrospinal fluid examination chemical examination protein examination, syphilis spirochete gelatin agglutination test, fluorimetric spirochete antibody adsorption test, blood routine, blood biochemistry six tests, blood electrolyte examination, blood glucose, CT examination MRI examination of spine. Prevention of genitourinary tract crisis: Since the liberation of China, due to the government strictly prohibit prostitution, and in some areas to implement the census and prevention, to the end of the 1950s this disease has been basically eradicated. In some countries in Europe and the United States, also due to early diagnosis and treatment and the application of penicillin and other drugs, so that the incidence of neurosyphilis significantly reduced, especially the main mass syphilis significantly reduced. However, in the past 10 years or so, new syphilis patients in China, especially meningeal and vascular syphilis patients have increased, and some also accompanied by AIDS, which must be vigorously promote medical health knowledge, strengthen the quality of education, so that people understand the dangers of sexually transmitted diseases, and even from certain systems to control, in order to prevent and control the occurrence of the disease from the source.
