Estimation of the prostate gland volume employing transrectal ultrasound provides important additional information in patients with benign and malignant diseases of the prostate. Twenty-five patients underwent transrectal ultrasound of the prostate prior to radical prostatectomy for organ-confined cancer of the prostate. The prostate gland volume was calculated employing two different methods. The prostate specimen weights were compared with the results of each of the volume estimation method. The prolate ellipse formula, widely used as an alternative to planimetry, demonstrated a correlation coefficient of r2 = 0.831. However, a variation of the prolate ellipse formula expressed as (width x width x height) x pi/6, which is easier to perform as described by Terris and Stamey, exhibited a correlation coefficient of r2 = 0.829. It appears to be a reliable means of estimating prostate gland volume, especially in cases in whom the original formula is difficult to apply.
经直肠超声评估前列腺体积可为前列腺良恶性疾病患者提供重要的额外信息。25例因局限性前列腺癌行根治性前列腺切除术的患者在术前接受了经直肠超声检查。采用两种不同方法计算前列腺体积。将前列腺标本重量与每种体积估计方法的结果进行比较。广泛用作面积测量替代方法的长椭圆公式显示相关系数r2 = 0.831。然而，如Terris和Stamey所述，一种表示为（宽×宽×高）×π/6的长椭圆公式变体，操作起来更容易，其相关系数r2 = 0.829。它似乎是一种可靠的前列腺体积估计方法，尤其是在难以应用原始公式的情况下。
