The prostate gland from cadavers of 12 intact adult male dogs euthanized less than 3 hour were used to compare prostatic volume measured by ultrasonography to volume measured by water displacement, and to determine specific gravity of the canine prostate. Prostate glands were scanned by transabdominal ultrasonography with a 4-7 MHz curved linear array transducer. The greatest craniocaudal (L), transverse (W), and dorsoventral (D) diameters of the prostate were recorded. Prostatic volume was calculated using formulas for an ellipsoid and for a box. Prostate glands were removed, and the prostate weight was measured and prostatic volume was measured by water displacement. The mean +/- SD specific gravity of the prostate was 1 +/- 0.05 (range = 0.90 to 1.09) g/cm. There were positive correlations (R2 = 0.94) between prostatic volume calculated from ultrasound measurement and measured volume. Measured prostatic volume (VM) can be predicted using the formula: VM = [1/2.6 (L x W x D)] + 1.8 (cm3).
使用12只安乐死时间少于3小时的成年雄性犬尸体的前列腺，将超声测量的前列腺体积与水置换法测量的体积进行比较，并测定犬前列腺的比重。使用4-7MHz的凸阵探头经腹超声扫描前列腺。记录前列腺最大的头尾径（L）、横径（W）和背腹径（D）。使用椭圆体公式和长方体公式计算前列腺体积。切除前列腺，测量前列腺重量，并通过水置换法测量前列腺体积。前列腺的平均±标准差比重为1±0.05（范围=0.90至1.09）g/cm。超声测量计算出的前列腺体积与测量体积之间存在正相关（R2=0.94）。测量的前列腺体积（VM）可使用公式预测：VM = [1/2.6 (L x W x D)] + 1.8 (cm3) 。
