Thirty-nine patients with benign prostatic hypertrophy, prostatic carcinoma, or prostatitis underwent ultrasonography using a transabdominal suprapubic approach. In both benign hypertrophy and prostatitis, the gland was enlarged and exhibited a homogeneous echo pattern, being hypoechoic in prostatitis and either hypo- or hyperechoic in hypertrophy. Carcinoma was characterized by focal areas of increased or decreased echogenicity with irregular margins. The various sonographic appearances are explained by correlation with the histological findings, and the advantages of the transabdominal approach are discussed. The authors suggest that widespread application of this technique will improve early detection of prostatic carcinoma.
39例患有良性前列腺增生、前列腺癌或前列腺炎的患者采用经腹耻骨上途径接受了超声检查。在良性增生和前列腺炎中，前列腺均增大，呈现均匀的回声模式，前列腺炎为低回声，增生则可为低回声或高回声。癌的特征是回声增强或减弱的局灶区域，边缘不规则。通过与组织学结果相关联来解释各种超声表现，并讨论经腹途径的优势。作者认为该技术的广泛应用将改善前列腺癌的早期检测。
