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. Examination items of genitourinary tract crisis: cerebrospinal fluid examination chemical examination protein examination, syphilis spirochete gelatin agglutination test, fluorometric dense spirochete antibody adsorption test, blood routine, blood biochemical six tests, blood electrolyte examination, blood glucose, CT examination, spinal MRI examination. 1, laboratory tests (1) cerebrospinal fluid examination is a sensitive indicator of neurosyphilis activity, neurosyphilis patients often show abnormalities, increased cell count, in (200-300) × 106 / L, mostly lymphocytes and a small number of plasma cells and monocytes. Cerebrospinal fluid protein is elevated, 0, 4 to 2 g/L, cerebrospinal fluid IgG is elevated, and sugar is generally normal. (2) Syphilis serological tests include non-specific STD investigation test, flocculent test and specific dense spirochete immunofluorescence adsorption test and dense spirochete braking reaction. FTA-ABS and TPI have a high rate of positivity, with TPI being more reliable. Positive cerebrospinal fluid VDRL and FTA-ABS have diagnostic significance. (3) Blood routine, blood biochemistry, electrolytes, blood glucose and immunological tests have differential diagnostic significance. 2.Other auxiliary examinations CT and MRI can show single or several small low-density infarct foci in the lesion tissue.
