In 21 patients adenocarcinoma of the prostate was staged preoperatively by digital rectal examination, computerized tomography and magnetic resonance imaging. Clinical staging was compared to the postoperative pathological staging. In 11 patients computerized tomography, magnetic resonance imaging and digital rectal examination findings were concordant with the histological examination showing tumors confined to the prostate. In 10 patients no correlation between preoperative staging and histology was noted. Of these cases 8 were understaged by computerized tomography, magnetic resonance imaging and digital rectal examination. In 1 patient magnetic resonance imaging showed false positive findings and in another staging with computerized tomography and magnetic resonance imaging was more accurate than digital rectal examination. Our experience indicates that computerized tomography and magnetic resonance imaging have limited value in the preoperative staging of prostatic carcinoma. Moreover, staging with computerized tomography and magnetic resonance imaging does not significantly improve the information gained by digital rectal examination.
对21例前列腺癌患者在术前通过直肠指诊、计算机断层扫描（CT）和磁共振成像（MRI）进行分期。将临床分期与术后病理分期进行比较。11例患者的CT、MRI和直肠指诊结果与组织学检查结果一致，显示肿瘤局限于前列腺。10例患者术前分期与组织学检查之间未发现相关性。在这些病例中，8例通过CT、MRI和直肠指诊分期过低。1例患者MRI显示假阳性结果，另1例患者CT和MRI联合分期比直肠指诊更准确。我们的经验表明，CT和MRI在前列腺癌术前分期中的价值有限。此外，CT和MRI联合分期并不能显著增加直肠指诊所获得的信息。
