Summary

We would like to present the benefits of the MRI/ TRUS fusion software targeted at prostate biopsies and demonstrate our practical experience with the fusion software over the course of two years. All patients with PSA < 20 ng/ml underwent three-parametric prostate MRI, they were classified by the PI-RADS v.2 system. The fusion was carried out with the ultrasound device BK Medical Flex Focus 400 with transrectal probe 8808 – 10Hz. We present a group of examined patients and their histological results, where we demonstrate the effect of the targeted biopsy. For all the biopsies performed, it verified prostate carcinoma in 48.25% of patients, and systematic biopsy verified prostate carcinoma in 35.46% of patients. For rebiopsy of the prostate, the targeted biopsy verified prostate carcinoma in 49.21% of the patients, and systematic biopsy verified prostate carcinoma in 29.68% of patients. Our work confirmed the effect of targeted prostate biopsy for primobiopsy, where we have shown that in our group prostate carcinoma in 9.09% of patients would have been missed if we had not performed targeted biopsy. Our results are consistent with the 2019 recommendations of the European Association of Urology (EAU).
