Bioplasm 9d nls-study was administered to18 patients. All studies was completed with 3D-reconstruction of an image, in 14 cases Bioplasm 9d nls-ultramicroscanning with spectral-entropic analysis was applied. Analysis of acquired results (step-by-step crosscuts, three-dimensional images and ultramicroscanning with spectral-entropic analysis) allowed to ascertain a diagnosis, localize a pathological process, evaluate size of pathological nidus and urethra affection character and check condition of surrounding tissues in all patients.
