    Objective: This study aimed to investigate the correlation between index lesion prostate imaging-reporting and data system (PI-RADS) version-2 score and histopathological outcomes of prostatectomy specimens. Materials and Methods: A total of 78 male patients with prostate cancer (PCa) treated with robot-assisted radical prostatectomy between August 2015 and June 2020 were included in this study. In this cohort, suspicious lesions on multiparametric magnetic resonance imaging (mpMRI) were scored according to PI-RADS version-2 criteria. MpMRI-targeted prostate biopsy was performed for all suspicious lesions with a PI-RADS score of >= 3 followed by systematic prostate biopsy. The relationship between index lesion PI-RADS score and histopathological outcomes of prostatectomy specimens were evaluated statistically. Results: The mean age of the patients was 65.0 +/- 7.0 years. The distribution of PI-RADS scores of 3, 4, and 5 of the index lesions were 6 (7.7\%), 29 (37.2\%), and 43 (55.1\%), respectively. Lower tumor volume and tumor volume ratio were observed in patients with a PI-RADS score of 3 when they were compared with patients with PI-RADS scores of 4 and PI-RADS-5 (p<0.001, for each). No significant correlation was found between index lesion PI-RADS score in mpMRI and clinically significant PCa in prostatectomy specimens (r<0.200, p>0.05). However, a significant correlation was observed between index lesion PI-RADS score and extracapsular extension (ECE), as well as seminal vesicle invasion (SVI) and pT stage (r=0.327, p=0.004
