    Abstract:
    Low-intensity laser therapy administered in the form of intravenous blood irradiation, transrectal and transurethral prostatic irradiation and their combination as preoperative preparation and correction of immunity disturbances in patients with benign prostatic hyperplasia (BPH) were studied. The response to the treatment was evaluated by positive changes in the immune status and bacterial contamination of the urine and prostatic tissue. Conventional preoperative preparation (uroantiseptics, antibiotics and phytotherapy) fails to correct signs of T-cell immunodeficiency, depression of phagocytic activity of neutrophils, significantly reduce bacteriurea. Laser therapy as intravenous laser blood radiation acts immunomodulatorily on cellular immunity and normalized the proportion of T-helpers of the first and second order (T-suppressors) and neutrophil phagocytosis. The antibacterial effect of this technique on urinary microflora and prostatic tissue is not very high. Local laser therapy is a potent immunostimulator of T- and B-lymphocytes, increased the index of immunoregulatory cells' proportion, activated phagocytosis of neutrophils. It has pronounced antibacterial effect against gram-negative urinary microflora and tissue of the prostate. Combined laser therapy produced the highest immunomodulating action on T-lymphocytes and immunostimulating one on B-lymphocytes, potentiated phagocytic ability of neutrophils, elevated index of the immunoregulatory cells, but was unable to correct their imbalance completely. Antibacterial effects of combined laser therapy were the highest, including the bacterial group Proteus-Providencia. Preoperative low-intensity laser therapy of BPH reduced the number of postoperative pyoinflammatory complications, hospital stay, severity of postoperative period.
