为筛选、评价前列腺癌的诊断方法，提高其诊断水平。对１９８７年～１９９７年收治的前列腺癌３９例根据症状、ＤＲＥ、ＴＲＵＳ、ＣＴ、ＭＲＩ、活检及瘤标检查，分析其诊断价值。结果：症状为排尿困难３４例（８７．２％），尿潴留１９例（４８．７％），血尿６例（１５．３％），会阴及腰骶部疼痛５例（１２．８％），尿失禁３例（７．６％）；本组全部行ＤＲＥ，阳性３２例（８２．０％）；ＴＲＵＳ３４例，阳性３１例（９１．２％）；病理活检２６例，其中经会阴穿刺１８例，阳性１６例（８８．０％），经直肠穿刺８例均阳性（１００％）；ＰＳＡ检测２５例，２２例（８８．２％）高于正常值；ＣＴ２６例，２０例（７６．９％）符合诊断；ＭＲＩ１９例，１６例（８４．２％）符合诊断。认为：ＤＲＥ及ＴＲＵＳ、ＰＳＡ检测及活检可作为筛选、诊断前列腺癌的主要方法；影像学检查对前列腺癌的分期、治疗以及预后评价有重要指导意义
To screen, evaluate the diagnosis of prostate cancer and improve its diagnostic level. Thirty-nine cases of prostate cancer admitted from 1987 to 1997 were diagnosed according to the symptoms, DRE, TRUS, CT, MRI, biopsy and tumor markers. Results: The symptoms were dysuria 34 cases (87.2%), urinary retention 19 cases (48.7%), hematuria 6 cases (15.3%), perineal and lumbosacral pain 5 cases (12.8% , Urinary incontinence in 3 cases (7.6%); DRE in this group was positive in 32 cases (82.0%); TRUS in 34 cases, positive in 31 cases (91.2%); pathological biopsy in 26 cases, 18 were positive, 16 were positive (88.0%), and 8 were rectal biopsy (100%). PSA was detected in 25 and 22 (88.2% .9%) met the diagnosis; MRI19 cases, 16 cases (84.2%) consistent with the diagnosis. It is considered that DRE, TRUS, PSA test and biopsy can be used as the main method to screen and diagnose prostate cancer. Imaging examination has important guiding significance for staging, treatment and prognosis of prostate cancer
