In order to clarify how precisely digital palpation gives information on prostatic size, evaluation of the size measurement of the prostate by means of transrectal sonography was performed on 1,543 subjects with various prostatic disorders. There was little agreement between the assessment of prostatic size by digital palpation and the ultrasonic measurement. The larger the prostate the less accurate was digital palpation. The prostatic size assessed by digital palpation was particularly dispersed widely in the prostate of 'hen's egg' size. It was proved that the size assessment by digital palpation was only effective statistically in a two-step differentiation, 'hen's egg' size and smaller. More complicated size classification was of little clinical value in digital palpation.
为了阐明直肠指诊测量前列腺大小的精确程度，对1543例患有各种前列腺疾病的受试者进行了经直肠超声检查来评估前列腺大小。直肠指诊评估的前列腺大小与超声测量结果之间几乎没有一致性。前列腺越大，直肠指诊的准确性越低。在“鸡蛋”大小的前列腺中，直肠指诊评估的前列腺大小尤其分散。结果证明，直肠指诊评估前列腺大小在“鸡蛋”大小及以下的两步鉴别中仅具有统计学意义。更复杂的大小分类在直肠指诊中临床价值不大。
