During the last two and a half years, transrectal prostate ultrasound has been used extensively at our institution. Three hundred and twenty patients have been evaluated in a double blind fashion as part of a study comparing digital rectal examination and transrectal prostatic ultrasound. Prostate cancer was detected in twenty three patients (7.2%); 13 had palpable nodules (4.1%) and 10 had non-palpable nodules (3.1%). Of the 23 patients, 19 had clinically localized (Stage B) prostate cancer. Clinical and pathologic staging correlated in 15 patients (79%). This compares favorably to clinical staging accuracy of 55% in patients prior to utilization of transrectal prostatic ultrasound.
在过去两年半的时间里，经直肠前列腺超声在我们机构得到了广泛应用。作为一项比较直肠指检和经直肠前列腺超声的研究的一部分，对320名患者进行了双盲评估。在23名患者（7.2%）中检测到前列腺癌；13名有可触及结节（4.1%），10名有不可触及结节（3.1%）。在这23名患者中，19名患有临床局限性（B期）前列腺癌。15名患者（79%）的临床分期与病理分期相关。这与在使用经直肠前列腺超声之前患者的临床分期准确率55%相比更具优势。
