Objective: Identify the prostate cancer detection rate in patients in whom underwent a saturation prostate biopsy as a rebiopsy from January 2005 to February 2015 at San Ignacio Hospital. Materials and methods: In San Ignacio hospital were performed from January 2005 to February 2015, 114 saturation biopsies. The investigators made a univariate analysis of the variables. The association between the variable was evaluated based on the T-test and Wilcoxon test. P < 0.05 was considered statistically significant. Finally, a regression model was performed to predict significant variables for prostate cancer. Results: The cancer detection rate using saturation prostate biopsy was 16.7% of which 84% were categorized as significant. A mean of 19 cores were obtained. There were statistically significant differences between patients with prostate cancer and healthy patients in the number of previous biopsies, number of samples, prostate volume and PSA density. Conclusion: Saturation prostate biopsy in our study has a prostate cancer detection rate of 16.7% and 84% of them were significant in this cohort of patients.
