Ultrahigh-frequency therapy in the treatment of chronic prostatitis

Ultra-high frequency (UHF) effects cover the ranges of 300-3000 MHz and are the main active factors of UHF therapy. The peculiarity of the electromagnetic field of this range is the possibility of localizing it on certain areas of the patient's body due to the use of special irradiating devices. The electromagnetic field, being a source of energy, can provide energy transformations in tissues. In the UHF range, the transition of the electromagnetic field energy into thermal energy is associated not only with conductivity intervals, but also with dielectric losses caused by oscillations of dipole molecules, the share of which increases with increasing frequency. Therefore, the absorption of UHF energy by tissues depends not only on the physical characteristics of the field, but also on the water content in the tissues. Blood, lymph, parenchymatous tissue, and muscles absorb radiation energy most strongly.

The degree of tissue heating is also determined by the level of their blood supply, which ensures thermoregulation and prevents overheating of irradiated areas during local microwave effects. Along with the purely energetic effect of radiation on organs and tissues, there are also information interactions in which it is not the energy that is important, but the information introduced into the system or the organism as a whole. In this case, microwave signals have a regulatory effect on the organism, acting as triggers. The perception of information is determined by the form and nature of the signal - continuous or pulsed. Special receptors for the perception of microwave signals have not been found, but an exceptionally high sensitivity of the whole organism to them has been established compared to isolated systems at the level of tissues, cells, intracellular organisms, enzyme-substrate complexes. As a result, the effect of microwave fields for the purpose of regulating the physiological state of internal organs can occur in three directions: on external receptor fields, directly on the corresponding internal organ, on the hypothalamus-pituitary system.

Depending on the frequency of microwave exposure and the associated depth of penetration into tissues, decimeter waves have a greater effect on the hypothalamus and internal organs, and centimeter waves (CMW) - on the receptor system at the corresponding localizations of exposure. In the treatment of patients with chronic prostatitis, we used MW with frequencies of 2375 MHz (wavelength 12.6 cm) and 2450 MHz (wavelength 12.5 cm). The depth of penetration of MW radiation into the patient's body is 35 cm.

The absorption of SMV is associated not so much with ion oscillations causing conductivity losses, but with dielectric losses associated mainly with the rotation of dipole molecules of free water. SMV effects are characterized by a high degree of locality. They have an irritating effect on receptors and cause reflex reactions. Thermal intensities of SMV over 10 mW/cm2 ^contribute to an increase in tissue temperature, increased blood flow and activation of metabolic processes in them. These changes are accompanied by corresponding shifts in the activity of hormonal systems, the nature of which changes as the intensity of SMV effect increases. Thus, low-thermal effects cause an increase in the functional activity of the body and its individual systems. Therefore, they are used in acute inflammatory processes. Medium-thermal effects that form an activation reaction are recommended for sluggish inflammatory processes.
