Transurethral Microwave Thermotherapy

Apparatus for Microwave Local Hyperthermy of Prostate: – quick relief from men's problems; – urinologist’s support; – outpatient treatment of prostate adenoma during single session. ALMHP-01 apparatus is intended for: – treatment of benign hyperplasia of prostate gland by the method of transurethral microwave therapy; – treatment of chronic nonspecific prostatitis by the methods of transrectal microwave hyperthermy and transrectal vibratory massage. Treatment of benign hyperplasia (adenoma) of prostate gland by the minimum invasive method of transurethral microwave thermotherapy. Guarantee of success in treatment of prostatitis by the methods of transrectal microwave hyperthermia and transrectal vibratory massage. The treatment session is carried out automatically according to a program. TREATMENT OF ADENOMA Transurethral Microwave Thermotherapy The applied method of transurethral microwave thermotherapy enables conducting the treatment of prostate adenoma in an outpatient manner, during a single one-hour session. This method is indicated for treatment of patients denied of surgical treatment because of contraindications to anaesthesia, and patients willing to escape surgical interference in case of no positive effect from pharmacotherapy. The therapeutic effect is conditioned by adenomatous tissue modification after its heating to 45…55 °С. The action is applied locally by a microwave transducer inserted in the prostate gland area with an urethral catheter that cools urethra during the treatment session. The treatment session is conducted automatically according to a program. The physician can make corrections during the session. The current values of temperature and power are displayed on the screen. The temperature is continuously monitored by an optical thermometric system. The temperature is monitored in the center of the prostate gland in the area of the maximum microwave action at the level of the urethral wall. To ensure the patient’s safety, the rectal wall temperature is also monitored with three temperature sensors. TREATMENT OF PROSTATITIS Transrectal Microwave Hyperthermia At transrectal microwave hyperthermia, the rectum wall and the area of posterolateral surface of prostate gland is heated up to 41 to 43 °С.The effective heating layer depth is 1 to 2 cm. The local action is applied by a miniature transducer of microwave energy. A special temperature sensor placed in the maximum emission area provides for continuous monitoring of the heating temperature and its maintaining at a set level. A special rectal catheter provides for cooling of the rectum wall and protects it from overheating. The elevated, as compared to diathermy, temperature and the cyclic heating mode provide for higher therapeutic efficiency of the action. As a result of microwave heating, the arterial and capillary blood flow is enhanced, the number of actively functioning rectum wall and prostate gland capillars is increased, the lymph flow is enhanced. The conducted treatment course results in normalization of the gland blood circulation, the local tissue resistance is increased, and the inflammatory process is terminated. To increase the efficiency of the action, thermotherapy by means of heating the fluid circulating in this catheter is conducted simultaneously with vibratory massage. The fluid temperature can be adjusted within 37 to 42 °С. Unlike diathermy, darsonvalization, laser therapy, this method provides for stronger action on the patient and his safety. Transrectal Vibratory Massage At transrectal vibration massage, the action, being a mechanical oscillation at a frequency of 1 to 5 Hz and amplitude of 1 to 5 mm is transferred through the rectal wall to the area of posterolateral surface of prostate gland and the urinary bladder fundus. Such action results in improvement of the drainage function of acinuses, the increase of the muscle tone of the prostate gland and rectum wall, enhancement of venous drainage, increase in the number of active capillars. Vibratory stimulant activates the adrenal pituitary-cortex system and increases the blood content of glucocorticoid hormones of cortisone and hydrocortisone type with pronounced anti-inflammatory effect. The vibratory massage is done using a special rectal catheter.
