The aim of the study was to evaluate the effect of two different methods of partial prostatectomy, to evaluate the influence of 96° ethanol injection on hyperplastic prostate and to compare the efficacy of ethanol injection with the efficacy of surgical treatment of the prostate. The study was performed in the years 20012003 in the surgical department of Dr. L. Kriauèeliûnas Small Animal Clinic. The surgical treatment (prostatectomy) was performed on 8 dogs using 2 methods: fillet and subcapsular. We compared the effectiveness and postoperative hystological evaluation of bioptats one and two weeks after surgery. We have performed ethanol injection on 5 dogs and evaluated the histological feature of prostatic tissues after injection to measure the effect of ethanol. The fillet method is technically simpler, shorter and the tissues of the prostate heal more quickly. Ethanol injection induces multi-focular coagulative necrosis, followed by fibrosis and atrophy of the prostate. This way of treatment is simpler and easier because there are no sections through prostate tissues. To avoid a section of the abdominal wall, a transurethral catheter can be used for the ethanol injection.
