The Efficacy of Mapping for Cognitive Prostate Biopsy

In this preliminary clinical study, 200 patients who underwent cognitive prostate biopsy under the guidance of transrectal ultrasonography between 01.03.2023 and 01.09.2023 by Marmara University Department of Urology, Department of Urooncology due to serum Prostate Specific Antigen (PSA) elevation and/or abnormal rectal examination findings will be included in the study. All patients will undergo prostate biopsy under local or general anesthesia with transrectal ultrasonography by a single surgeon after mapping or report is extracted by a single genitourinary radiologist in the Department of Radiology of our hospital. In the power analysis, 200 patients were included in the study with the prediction that the efficacy difference would be calculated as 5%. All patients will be randomized to two equal groups by the flip-flip method. 1. Multiparametric Prostate Magnetic Resonance Imaging and reports of the mapped patients will be examined and cognitive prostate biopsy will be performed by looking at the map (Sample Figure 1,2) created by the same urologist and the same radiologist (Sample Figure 1,2). Standard 12 core (6 peripheral zones from both lobes) will be sampled and 4 extra biopsies will be taken from Prostate Imaging-Reporting and Data System (PI-RADS) Category 3-4-5 areas in the mapping. 2. Based on the Multiparametric Prostate Magnetic Resonance Imaging reports and images, without mapping by the radiologist, only the standard 12 core (6 from each peripheral zone from both lobes) determined cognitively by the urologist and 4 extra biopsies from the Prostate Imaging-Reporting and Data System (PI-RADS) Category 3-4-5 areas described in the report will be taken. And then the biopsy results will be compared to see the efficacy of mapping
