Comparative histopathology, microradiography and per-rectal ultrasonography of the prostate using cadaver specimens.

A technique for examining cadaver prostates by per-rectal ultrasonography has been developed. The ultrasonic plane was defined and corresponding sections taken for microradiographic and histopathological examination. The technique has enabled a comparison to be made of the structural changes that occur in the prostate in disease states and the corresponding ultrasonic features.
