Paper Abstract

According to the world statistics, from 30 to 60 percent of elderly male population suffer from chronic prostatitis in different countries. This disease has a number of consequences such as urino-genital inflammation, dysuria, perineal pain, reduction in the physiological activity of smooth muscles, blockage of the anus passages with micro-organism vital activity products, appearance of stagnant zones and low blood circulation complicated by disorders of the sexual function. Most of these features make it difficult to use standard drug therapies with antibiotics or immunocorrectors. For that reason, the objective of this study is to develop and to investigate a novel combined electrolaser therapy which improves drug delivery in the prostate gland and simultaneously provides an independent physiotherapeutic effect. The main feature of this therapy is the utilization of two diode lasers emitting in the red (0.67 micrometer, 10 mW) and in the infrared (0.85 micrometer, 1 W) spectrum ranges in combination with transurethral electrostimulation. An electrolaser catheter containing both hollow cylindrical electrodes and an axial optical fiber to deliver laser radiation was brought along the urethra to the seminal vesicles. The red laser in combination with a photosensitizer ('Photosens,' Russia) was used to realize the antibacterial treatment of the urethra. The infrared laser was employed to heat the prostate gland and to stimulate the blood perfusion without thermal damage of tissues. The laser heating of the prostate at a local tissue temperature of 41 degrees Celsius in combination with the electrostimulation provided approximately a 4.5-fold increase in the blood flow. The realization of an additional mode of photovacuum therapy inside the urethra together with the electrostimulation made it possible to 'clean' the anus passages and to improve the DNA diagnosis reliability in respect of the urogenital infectious remainder. The clinical data obtained in 980 patients, who had been undergoing the treatment since 1994 till 1999 in accordance with the electrolaser method in Russia, are analyzed.
