Seventy six patients underwent transrectal ultrasound examination of the prostate prior to radical prostatectomy. All radical specimens were weighed and measured when freshly excised. Corresponding measurements calculated using transrectal ultrasound dimensions were retrospectively compared with those of the freshly excised glands. Estimation of gland volume by ultrasound measurement, utilizing the prolate ellipse formula [Width x Height x Length) x 0.70 was applied to a control group of 19 patients, and a close correlation (r = 0.77) between ultrasound estimated volume and actual weight was shown. A modified prolate ellipse formula, using the factor of 0.70, appears to be a more reliable means of estimating gland volume with transrectal ultrasound than the original formula [Width x Height x Length) x 0.523).
76例患者在前列腺癌根治术前接受了经直肠超声检查前列腺。所有根治性标本在新鲜切除时均进行称重和测量。将经直肠超声测量计算出的相应测量值与新鲜切除腺体的测量值进行回顾性比较。利用长椭圆形公式[宽×高×长)×0.70，通过超声测量对19例患者的对照组进行腺体体积估计，结果显示超声估计体积与实际重量之间存在密切相关性(r = 0.77)。与原始公式[宽×高×长)×0.523)相比，使用0.70系数的改良长椭圆形公式似乎是经直肠超声估计腺体体积更可靠的方法。
