Factors predicting transrectal ultrasound-guided systematic prostate biopsy failure

Objectives: To determine the factors that predict failure of systematic prostate biopsy by examining clinical, laboratory, and radiological parameters patients for whom cancer was detected magnetic resonance imaging (MRI)-targeted but not biopsy. Methods: Patients were included in this study if they had undergone combined targeted They biopsy-naive lesions with a Prostate Imaging Reporting Data System (PIRADS) score ≥ 3 peripheral zone on MRI. The biochemical, findings groups without compared. Results: A total 100 an index lesion MRI-targeted In 43 (43%) patients, no biopsy, whereas it other 57 (57%). Statistically significant differences found between two terms volume PSA density (p < 0.001 p 0.001, respectively). Moreover, univariate multivariate logistic regression analyses indicated size are independent predictors failure. Conclusions: success may be lower high low size.
