The dimensions of the prostatic gland in castrated adult dogs, as assessed by ultrasonography, is currently not yet reported in veterinary literature. The current study was aimed at reporting the prostatic dimensions in castrated dogs and investigate the relationship between the dogs' body weight and prostate size. A second aim of the study was to investigate whether there was a relationship between the dogs' age and prostate dimensions. A prospective, single-centre, observational study was conducted and 72 privately owned, adult, male castrated dogs with a range of breeds and ages met the final inclusion criteria. The subjects were divided into three categories based on body weight.
A Kruskal-Wallis test found prostatic length and prostatic depth in the longitudinal orientation to be significantly different among the 3 categories (P < 0.005), with an increase in both prostatic length and prostatic depth with increasing body weight. Linear regression of the data set provided comprehensive formulas calculating prostatic length and depth based on the body weight of the dog (r of 0.69 and 0.53 for prostatic length and depth respectively). Kendall's Tau rank test showed no correlation between dogs' age and prostate dimensions (P > 0.100).
The current study is the first to provide a comprehensive, weight-based reference for the canine prostate gland of castrated dogs when assessed on ultrasonography.
目前兽医文献中尚未报道经超声评估的去势成年犬前列腺的尺寸。本研究旨在报告去势犬的前列腺尺寸，并研究犬体重与前列腺大小之间的关系。研究的第二个目的是调查犬年龄与前列腺尺寸之间是否存在关系。进行了一项前瞻性、单中心、观察性研究，最终符合纳入标准的是 72 只具有不同品种和年龄的私人拥有的成年雄性去势犬。根据体重将这些动物分为 3 组。
Kruskal-Wallis 检验发现 3 组之间前列腺的纵向长度和深度有显著差异（P<0.005），随着体重的增加，前列腺的长度和深度都增加。对数据集的线性回归提供了基于犬体重计算前列腺长度和深度的综合公式（前列腺长度和深度的 r 值分别为 0.69 和 0.53）。Kendall 的 Tau 秩检验显示犬年龄与前列腺尺寸之间无相关性（P>0.100）。
本研究首次为经超声评估的去势犬前列腺提供了基于体重的全面参考值。
