To evaluate the correlation between the presence of bladder debris on ultrasound and urinalysis results in the emergency department setting.
Adult patients presenting to the emergency department with an ultrasound of the bladder and a urinalysis performed within 24 h of the ultrasound were included in this retrospective study. Two radiologists in consensus evaluated for the presence or absence of debris within the bladder. Urinalysis results were recorded including continuous variables (specific gravity and pH) and categorical variables (presence of occult blood, bilirubin, ketones, glucose, protein, urobilinogen, nitrite, leukocyte esterase, white blood cells, and red blood cells). The presence and absence of white and red blood cells were defined as > 5 cells/high-powered field. To control the experimentwise type I error rate at 0.05, a Bonferroni-corrected significance level of 0.0042 was used to determine significant associations.
The presence of bladder debris was associated with the presence of urobilinogen, nitrite, and white blood cells (p = < 0.0001, 0.0005, and 0.0004, respectively).
Bladder debris in the emergency department setting correlates with urinalysis laboratory values suggesting a urinary tract infection. Therefore, the presence of bladder debris should elicit the recommendation of a urinalysis in such a setting.
评估急诊环境下膀胱内碎屑存在与尿液分析结果之间的相关性。
本回顾性研究纳入了在急诊就诊行膀胱超声检查且在超声检查后 24 小时内进行尿液分析的成年患者。两位放射科医生共同评估膀胱内是否存在碎屑。记录尿液分析结果，包括连续变量（比重和 pH 值）和分类变量（是否存在潜血、胆红素、酮体、葡萄糖、蛋白质、尿胆原、亚硝酸盐、白细胞酯酶、白细胞和红细胞）。白细胞和红细胞的存在与否定义为> 5 个高倍视野/细胞。为了将实验性Ⅰ类错误率控制在 0.05，使用 Bonferroni 校正的显著性水平 0.0042 来确定显著关联。
膀胱内碎屑的存在与尿胆原、亚硝酸盐和白细胞的存在相关（p<0.0001、0.0005 和 0.0004）。
在急诊环境下，膀胱内碎屑与尿液分析实验室值相关，提示存在尿路感染。因此，在这种情况下，膀胱内碎屑的存在应提示进行尿液分析。
