摘要: Urologists routinely use the systematic sextant needle biopsy technique to detect prostate cancer. However, recent evidence suggests that this has a significant sampling error and data based upon whole-mounted step-sectioned radical prostatectomy specimens using three-dimensional computer-assisted simulator an increased detection rate is possible laterally placed biopsies. The simulated 10-core pattern (traditional cores four biopsies in right left apex mid portion of gland) was shown be superior traditional biopsy. objective pilot study confirm higher cancer obtained patients. We reviewed on 35 consecutive patients with pathologic diagnosis biopsied by single urologist pattern. frequency positive determined for each core. Additionally, patterns were compared respect rate. Of diagnosed cancer, 54.3%(19/35) only. resulted additional 45.7%(16/35) being solely had highest when cores. In conclusion, protocols five region anatomical model are used
