Cholestasis assessment by activity of antioxidant enzymes and composition of plasma lipoproteins in patients with liver diseases]

23 patients with benign prostatic hyperplasia (BPH) aged 60-82 years underwent transurethral resection (TUR) of the prostate in different periods after thermal treatment which had appeared uneffective or brought complications. In the performance of the endoscopic techniques we found macroscopic changes of the prostatic parts of the urethra and bladder cervix characteristic for certain thermal impact (energy, power, site of exposure). Intraoperative bleeding of prostatic tissue was also different depending primarily on the time which had passed after the thermal treatment. Minimal bleeding occurred at least 3 months after the thermotherapy. Thus, thermal treatment of the prostate can be used in combined treatment of BPH for reducing intra- and postoperative hemorrhage due to subsequent TUR. Among the methods of thermal therapy, transurethral microwave thermotherapy is preferable as minimally invasive and deeply penetrating into the depth of the prostatic gland with maximal effect. TUR of the prostate should be performed not earlier than 3 months after thermotherapy which is indicated only for patients at high risk of intraoperative hemorrhage because of unaffected circulation. Therefore, it is desirable to include transrectal dopplerography of the prostate to urological examination of BPH patients.
