ABSTRACT
30 benign prostate hyperplasia (BPH) and 20 prostate carcinoma patients whom confirmed pathologically, admitted in recent 4 months, were reviewed with transrectal ultrasonogram of prostate. The BPH was characterized by transversely elongated, symmetrical shape, evan capsule with regular continuity and homogenous or hyperechogenicity. But prostate carcinoma showed anteroposteriorly elongated, asymrnetrical shape, irregular, thickened or interrupted capsule and hypoechogenicity or mixed echogenicity. The diagnostic accuracy of BPH was 97% but the prostate carcinoma was 85%. The resolution and precision of the prostate image, especially on the prostate capsule, were more accurate than any other imaging modalities and the combination with them, we can establish the most accurate staging and appropriate treatment plan.
