One hundred and twenty-one transrectal ultrasound examinations of the prostate were performed between August and October of 1987. Indications included screening in 41 patients, evaluation of bladder outlet obstruction in 63 patients, evaluation of palpable nodules in 6 patients, and evaluation after transurethral resection of the prostate in 11 patients. A total of five patients were discovered to have prostate cancer after biopsy of a hypoechoic lesion in a normal feeling prostate by digital rectal examination. One patient was from the screening group, two patients with bladder outlet obstruction and two patients from the postransurethral resection group. All six patients with palpable nodules were diagnosed as having a cancer: Stage B2 on the rectal examination and two of the six patients were upstaged to Stage C by ultrasound criteria. In our hands transrectal ultrasound of the prostate is a valuable adjunct in the urological armamentarium with clear application in the diagnosis and staging of prostate cancer.
1987年8月至10月间，共进行了121例经直肠超声检查前列腺。检查指征包括：41例患者用于筛查，63例患者用于评估膀胱出口梗阻，6例患者用于评估可触及结节，11例患者用于经尿道前列腺切除术后评估。通过直肠指检在正常质地前列腺中对低回声病变进行活检后，共发现5例前列腺癌患者。其中1例来自筛查组，2例有膀胱出口梗阻，2例来自经尿道前列腺切除术后组。所有6例可触及结节的患者均被诊断为患有癌症：直肠指检为B2期，其中6例中有2例经超声标准分期为C期。在我们手中，经直肠超声检查前列腺是泌尿外科设备中的一项有价值的辅助手段，在前列腺癌的诊断和分期中有明确应用。
