Imaging of tbe Prostatic Carcinoma and Benign Prostatic Hyperplasia by Transrectal Ultrasound / 대한비뇨기과학회지

ABSTRACT

Transrectal ultrasonography is one of the most available techniques to evaluate prostatic disease and is far more accurate than conventional ultrasonography. A retrospective review of ultrasonographic characteristics of the prostate was made in an attempt to define the ability of the technique to distinguish benign from malignant prostatic disease. Analysis included evaluation of the capsule, abnormal foci (echo brightness, echo thickness) and calcification. Transrectal ultrasonography was performed in 79 cases and the results were compared with the pathologic results of prostatic tissue obtained by transperineal ultrasound guided or transurethral prostatic resection. Acoustic characterization of abnormal small foci within the gland has a moderate degree of overlap, but may suggest the differentiation of benign and malignant disease.
