AIM: To evaluate early prostate cancer cryoablation functional and oncological results in comparison with results of extraperitoneoscopic radical prostatectomy. MATERIALS AND METHODS: We analyzed early results of surgical treatment of 285 patients with prostate cancer: 42 of them had undergone total cryoablation (Group 1) while the rest of them had been treated by radical laparo- and extraperitoneoscopic prostatectomy. For comparative assessment of prostate cryoablation results, 42 patients from Group 2 randomized in accordance with their age, stage of disease, Gleason, prostate-specific antigen, and prostate volume were selected. In compliance with the results of pre-surgical examination, all the patients had low oncological risk and were not concerned in sexual function. Volume of prostate was from 22 to 65 cm3, prostate-specific antigen level was from 4.1 to 10 ng/mL, and level of neoplastic process differentiation using Gleason grading system was from 6 to 7a (3 + 4) scores. RESULTS: Patients after prostate cryoablation in early post-surgical period felt lower intensity of postoperative pain compared with those who had undergone prostatectomy. Follow-up period up to 12 months manifested significant true reduction of prostate-specific antigen level in both groups of patients. Frequency of stress-induced enuresis in Group 1 was not observed. CONCLUSION: Radical prostatectomy is still the traditional treatment of choice in the case of localized prostate cancer. But we can draw the conclusion that cryoablation is an effective low-invasive method for treatment of low oncological risk patients, which gives the opportunity both to achieve good oncological results and to preserve high life quality.
