Determination of prostatic size by rectal examination is inaccurate if objective and reproducible values are desired. Sonometrics, a combination of transrectal sonography and biometrics, is a simple method to determine prostatic weight. The optomanual image analyzing system (BIT PAD-TRS 80) consists of a digitizer tablet, cursor, processing unit and keyboard (TRS 80). The photographic records or the image of the prostate on the scan can be measured with the optomanual image analysis system by tracing the circumference of the prostate. Using the computer one can calculate length, area and circumference of the sonogram. When the postoperative and sonometrically estimated weights were compared a good correlation coefficient was found. The studies on age-dependent growth of the prostate show an age-volume relationship similar to that shown in the study by Swyer. As demonstrated in patients with hypothalamic hypogonadotropic hypogonadism change in prostatic volume also can be assessed in small prostates.
如果需要客观且可重复的值，通过直肠指检确定前列腺大小是不准确的。超声测量法，即经直肠超声检查和生物测量学的结合，是一种确定前列腺重量的简单方法。光学手动图像分析系统（BIT PAD - TRS 80）由数字化仪平板、光标、处理单元和键盘（TRS 80）组成。前列腺的照片记录或扫描图像可以通过光学手动图像分析系统追踪前列腺的周长来测量。使用计算机可以计算超声图的长度、面积和周长。当比较术后重量和超声测量估计的重量时，发现了良好的相关系数。关于前列腺随年龄增长的研究表明，年龄与体积的关系与斯怀尔研究中所示的相似。如下丘脑性性腺功能减退性腺功能减退患者所示，前列腺体积的变化在小前列腺中也可以评估。
