[Analysis of efficacy of extensive systematic transperineal TRUS-guided cor biopsy of the prostate].

The paper presents the technique of extensive systemic transperineal TRUS-guided cor biopsy of the prostate. Some aspects of the patients' safety and quality of biopsy cores are considered. The analysis of TNM stages of the detected cancers (55 cases out of 142 patients who have undergone systemic biopsy) showed 65.4% of local cancer (T1-2). The quality of cores was adequate for histological examination in 92.8% cases. None serious complications was reported. Only in two of ten patients subjected to radical prostatectomy stage T2 was changed to stage T3 in the absence of metastases to regional lymph nodes and distant metastases.
