Transrectal endosonography is one of the most sensitive techniques to evaluate prostatic disease and is far more accurate than conventional sonography. A retrospective review of sonographic characteristics of the prostate was made in an attempt to define the ability of the technique to distinguish benign from malignant disease. Analysis included evaluation of the capsule (smoothness, regularity, and/or invasion), abnormal foci (echogenicity, margination, brightness, thickness, and symmetry), and presence of acoustic shadowing and/or enhancement from the abnormal foci. Evaluation of 443 pathologically proved cases (the majority being large lesions) showed that differentiation between benign and large and/or invasive malignant disease may be suggested by results of transrectal endosonography. However, there is still great overlap of the sonographic appearances.
经直肠超声检查是评估前列腺疾病最敏感的技术之一，远比传统超声检查准确。我们对前列腺的超声特征进行了回顾性研究，以确定该技术区分良性疾病与恶性疾病的能力。分析内容包括对包膜（光滑度、规则性和/或浸润情况）、异常病灶（回声性、边缘、亮度、厚度和对称性）以及异常病灶有无声影和/或增强的评估。对443例经病理证实的病例（大多数为大病灶）进行评估后发现，经直肠超声检查结果可能有助于区分良性疾病与大的和/或浸润性恶性疾病。然而，超声表现仍存在很大重叠。
