The broad spectrum ultrasonic vibrations emitted by the piezoelectric transducer 4 affect the prostate gland 16. At the same time, the outer lining of the rectal probe 5 serves, for example, as an indifferent electrophoresis electrode and is connected to one of the outputs of the current generator 13, the second output of which is connected to the outer lining of the urethral probe 9, supplied to the prostate gland 16 from the side opposite to the rectal probe 5 (FIG. 2). Through probes 5 and 9, medicinal substances in the liquid phase are brought under pressure P to the prostate gland 16. The ultrasonic vibrations emitted by the piezoelectric transducer 4, the passage through the prostate gland 16, are sensed by the piezoelectric transducer B placed on the urethral probe 9 operating in the reception mode of the ultrasonic vibrations, due to the fact that the electronic key 6 is closed. . The output signal of the piezoelectric transducer 8 through the electronic key 12 is fed to the input of the amplitude discriminator 13, the output of which forms rectangular pulses, the duration of which depends on the state of the prostate gland 16. These pulses go to the input of the pulse width meter 14. The result of measuring the pulse duration comes from outputs meter duration 14 to the outputs 15 of the device. When the electronic key 6 is open, the output signal of the generator 1 through the power amplifier 7 is supplied to the piezoelectric transducer 8, the radiation of which affects the prostate gland 16, while the electronic keys 2 and 12 are closed. Monitoring of the state of the prostate gland in the course of treatment is carried out according to the measurement result generated at the outputs 15 of the device, which 1st can be received for Processing in a computer. Higher treatment efficacy is provided by exposing the prostate iron-ultrasonic oscillations in a wide range of frequencies.
