前立腺 (肥大症を中心に)

Abstract

In normal cases, prostatic section shows triangular shape and inner gland occupies a small part in only upper sections as a echogenic portion. In prostatic hypertrophy cases, inner gland occupies more part of the prostate and outer gland is shown as a half moon shape, in late stage of hypertrophy, inner gland occupies almost whole the part of the prostate, and compressed outer gland is visualized as an orange peel in postero-inferior portion. In some cases with prostatic hypertrophy, some nodules were clearly observed, as a more echo genic round portions. These findings mentioned above are very interesting in connection with developmental mechanism of benign prostatic hypertrophy.
