Sagittal and transverse ultrasonographic images of the prostate gland were obtained in 100 healthy adult intact male dogs. Prostatic length, width, and height on transverse and sagittal images as well as the presence of prostatic cysts were determined. Linear regression and correlation analysis were performed between prostatic parameters (length, width, height on sagittal and transverse images, and estimated volume) and parameters related to body size (body weight, body height, left kidney length and aortic diameter) and age of the dogs. Significant positive correlations were found between all prostatic parameters and parameters related to body size and age. Maximum predicted values for prostatic parameters for a given body weight and age were determined based on the upper limit of the 95% confidence interval of the mean predicted values. Such values should represent a useful tool for ultrasonographic evaluation of the prostate in the dog. Prostatic cysts were found in 14% of the dogs.
对100只健康成年未阉割雄性犬获取了前列腺的矢状面和横断面超声图像。测定了横断和矢状面图像上前列腺的长度、宽度和高度以及前列腺囊肿的存在情况。对前列腺参数（矢状面和横断面图像上的长度、宽度、高度以及估计体积）与犬的体型相关参数（体重、体高、左肾长度和主动脉直径）及年龄进行了线性回归和相关性分析。发现所有前列腺参数与体型相关参数及年龄之间均存在显著正相关。根据平均预测值95%置信区间的上限，确定了给定体重和年龄下前列腺参数的最大预测值。这些值应是超声评估犬前列腺的有用工具。在14%的犬中发现了前列腺囊肿。
