Thirty-three cases with clinical symptoms and signs suspecting prostatic cancer or other prostatic entities with abnormal ultrasonic reflection were diagnosed by transperineal prostatic biopsy guided by intrarectal ultrasonic probing. This procedure more accurate and safer than the conventional one. It seems quite useful clinically in the differential diagnosis of prostatic carcinoma, particularly the early cases from the other prostatic diseases.
33例有前列腺癌或其他前列腺疾病临床症状和体征且超声反射异常的患者，经直肠超声引导下经会阴前列腺穿刺活检确诊。该方法比传统方法更准确、更安全。它在前列腺癌的鉴别诊断中，尤其是早期病例与其他前列腺疾病的鉴别诊断中，临床应用似乎相当有用。
