Prostatography by perineal puncture is a remarkable technique for examination of patients with prostatic disorders. The authors prefer transperineal puncture of the prostate for the following reasons: 1) It is carried out under the guidance of the free right index finger in the rectum; 2) Infection has never been observed; 3) Stimultaneous biopsies taken from various regions of the prostate, for histological examination, is possible on changing the position of the needle. Perineal prostatography enabled one to: 1. Precisely see the extent of a cnacer. 2. Discover lesions provoked by the tumor (necrotic zones, opacities). 3. Assert that extracapsular extension has taken place when the contrast medium has diffusep outside of the prostatic capsule. 4. Possibly establish the presence of latent carcinoma within a prostatic adenoma. These being all useful notions for treatment.
经会阴穿刺前列腺造影术是检查前列腺疾病患者的一项卓越技术。作者倾向于经会阴穿刺前列腺，原因如下：1）在直肠内右手食指的引导下进行；2）从未观察到感染；3）在改变针的位置时，能够从前列腺的不同区域同时获取活检组织进行组织学检查。经会阴前列腺造影术能够：1. 精确观察癌肿的范围。2. 发现肿瘤引发的病变（坏死区域、不透明区）。3. 当造影剂扩散至前列腺包膜外时，确定已发生包膜外浸润。4. 有可能确定前列腺腺瘤内隐匿性癌的存在。这些对于治疗均为有用的概念。
