HISTOLOGICAL CHANGES IN PROSTATE TISSUE UNDER THE INFLUENCE OF DORNIER MEDILAS D UROBEAM 940NM LASER WHILE APPLYING METHOD OF MODIFIED VAPORIZATION OF BENIGN ADENOMATOUS HYPERPLASIA OF PROSTATE

The results of morphological ivestigation of prostate tissue after vaporization prostatectomy by Laser Dornier Medilas D UroBeam and transurethral prostate resection in patients with benigh prostatic hyperplasia is shown. We found that the successive use laser Dornier Medilas D Urobeam at power 175-250 W and transurethral resectionof prostate provides diminishing of area of coagulative necrosis which prevents formation of massive scab. At the same time the photoselective to haemoglobin as a result of vaporization draws coagulative necrosis of content of vessels in areas with unchanged stroma and prevents bleeding.
