Study of Current Practice Which Compare the Rate of Prostate Cancer by Using 2 Kind of Transrectal Biopsies: 3 by IRM-echography Image Fusion and 12 Systematized Guided Echographies.

Not Applicable
Completed
Conditions
Prostate Cancer
Interventions
Procedure: systematic biopsies
Procedure: Targeted biopsies guided by a fusion of MRI and ultrasound- images
Registration Number
NCT02050542
Lead Sponsor
Assistance Publique - Hôpitaux de Paris
Brief Summary

The purpose of the study is to show that 3 targeted biopsies on the suspicious image detected by IRM, guided by a fusion of MRI and ultrasound- images with the Koelis ® system, will get no lower rate of cancer detection than those obtained by 12 systematic transrectal ultrasound-guided biopsies of the prostate.

Detailed Description

The act of current practice evaluated by this research is the act of prostate biopsies : the patient will have to undergo 12 systematized transrectal echography guided biopsies of the prostate and 3 additional biopsies targeted on the suspicious lesion detected with MRI, which are both done in current practice.

* A first operator is not informed of the location of the target. He will perform a series of 12 systematic transrectal ultrasound-guided biopsies of the prostate.

* Immediately after the second operator will perform 3 additional targeted biopsies on the suspicious image detected by IRM, guided by a fusion of MRI and ultrasound- images with the Koelis ® system

Act added by the research: Using a fusion of MRI - ultrasound images software system (Koelis ®).
