OBJECTIVES
The purpose of this study is to evaluate the effects of substrate composition and storage time on urine specific gravity in dogs.
METHODS
A descriptive cohort study of 15 dogs. The urine specific gravity of free catch urine samples was analysed during a 5-hour time period using three separate storage methods; a closed syringe, a diaper pad and non-absorbable cat litter.
RESULTS
The urine specific gravity increased over time in all three substrates. The syringe sample had the least change from baseline and the diaper sample had the greatest change from baseline. The urine specific gravity for the litter and diaper samples had a statistically significant increase from the 1-hour to the 5-hour time point.
CLINICAL SIGNIFICANCE
The urine specific gravity from canine urine stored either on a diaper or in a non-absorbable litter increased over time. Although the change was found to be statistically significant over the 5-hour study period it is unlikely to be clinically significant.
目的
本研究旨在评估底物成分和储存时间对犬尿液比重的影响。
方法
对15只犬进行描述性队列研究。使用三种不同的储存方法，在5小时时间段内分析自由采集尿液样本的尿液比重；分别为密闭注射器、尿布垫和不可吸收猫砂。
结果
在所有三种底物中，尿液比重均随时间增加。注射器样本与基线相比变化最小，尿布样本与基线相比变化最大。猫砂和尿布样本的尿液比重在1小时至5小时时间点有统计学显著增加。
临床意义
储存在尿布或不可吸收猫砂中的犬尿液比重随时间增加。尽管在5小时研究期间发现这种变化具有统计学显著性，但不太可能具有临床意义。
