经直肠前列腺超声检查对前列腺癌的诊断和分期具有重要意义。由于前列腺癌多数发生在前叶,超声检查常显示有特征性的低回声图像,其实用价值不亚于直肠指检和CT、MR的影像诊断。另外,该方法简便、重复性强、费用低廉,易为病人所接受。作者于1985年7月至1987年5月,使用Brud & Kjaer 1846型超声仪进行了224例经直肠前列腺超声检查,其中118例通过耻骨后根治性前列腺摘除、前列腺穿刺活检和TURP等方法获得前列腺的病理诊断,本文重点对该118例进行回顾性分析,以评价超声对前列腺癌的诊断价值。
Transrectal ultrasound of the prostate is important for the diagnosis and staging of prostate cancer. Since most prostate cancers occur in the anterior lobe, ultrasonography often shows characteristic hypoechoic images. Its practical value is no less than digital rectal examination and CT, MR imaging diagnosis. In addition, this method is simple, reproducible, and inexpensive, and is easily accepted by patients. From July 1985 to May 1987, 224 cases of transrectal ultrasound were performed on the Brud & Kjaer 1846 Ultrasound System. Among them, 118 cases were treated with retropubic radical prostatectomy, prostate biopsy, and TURP. The pathological diagnosis, this article focuses on a retrospective analysis of 118 cases to evaluate the diagnostic value of ultrasound for prostate cancer.
