DEPORRA-CoProst: Assessment of New Fluorescence Imagery Techniques Using Prostate Chips From Transurethral Resections

The aim of this study is divided in 4 different steps: * the first step has two different purpose: assess the impact of the storage medium of fresh prostatic chips on fluorescence signal and adjust the entire chain (immunolabelling,counter-stain and imaging), * the second step is the adaptation of immunolabelling protocol on histopathology slides, using fresh prostatic tissue, * the third step is to validate the use of: 1. the medical device created by the FEMTO-ST institute use for the detection of fluorescence signal on fresh tissue, 2. the Light-CT scanner use for tissue structural observation. * the four step is to check the preservation of morphological structure of tissue under the effect of laser excitation from the medical device.
