Pre-operative staging, using transrectal prostatic sonography and CT, was carried out in 30 patients with cytologically confirmed carcinomas of the prostate and the results compared with the clinical findings. All patients underwent radical prostatectomy and the pre-operative findings could be verified histologically. Transrectal prostatic sonography is better than CT or clinical examination for determining local tumour spread or penetration of the capsule. A high proportion of enlarged pelvic lymph-nodes shown by CT had non-specific changes; failure to demonstrate enlarged nodes excludes lymph node metastases with considerable certainty. Transrectal prostatic sonography provides a higher degree of information regarding local tumour spread, whereas CT indicates the presence or absence of lymph node metastases.
对30例经细胞学确诊的前列腺癌患者进行了术前分期，采用经直肠前列腺超声检查和CT检查，并将结果与临床检查结果进行比较。所有患者均接受了根治性前列腺切除术，术前检查结果可通过组织学验证。在确定肿瘤局部扩散或包膜侵犯方面，经直肠前列腺超声检查优于CT或临床检查。CT显示的盆腔淋巴结肿大中有很大一部分有非特异性改变；未能显示淋巴结肿大可相当肯定地排除淋巴结转移。经直肠前列腺超声检查能提供更多关于肿瘤局部扩散的信息，而CT则可显示有无淋巴结转移。
