A method for the differential diagnosis of urethritis in men

摘要

A method for differential diagnosis of urethritis in men by laser Doppler flowmetry, characterized in that they use an endoscopic probe using a helium neon laser with a wavelength of 0.63 μm, which is installed directly in the urethra before the transition of the anterior to the posterior region, then the microcirculation changes are analyzed graphically records and calculate the parameters according to the formula:, where I is the microcirculation index, which reflects the relationship of microcirculation indicators with the amplitude-frequency spectrum, M is the microcirculation index circulation in perfusion units, α is the standard deviation, A is the maximum amplitude in each group of oscillations of the amplitude-frequency spectrum, F is the maximum frequency in each group of oscillations, α is the slow rhythms 1-3 cycles, min, LF are slow rhythms 4-12 cycle, min, HF - fast rhythms 12-36, min, CF - pulse fluctuations, after which they analyze the changes in basal blood flow and amplitude-frequency spectrum with a microcirculation index of 6.0 units. diagnose the presence of opportunistic microflora, and with a microcirculation index of 2.7 units. - pathogenic infection.
