摘要
收集干净的排空尿液样本创伤很小,但尿液通过未经消毒的尿道和外生殖器时会造成污染。丢弃最初的尿流可减少这些污染物。本研究假设,使用中段尿液收集装置会比干净收集的排空尿液减少细菌和细胞污染。这项描述性横断面研究采用标准清洁捕捉(SCC)、中游尿液收集装置(MCD)和膀胱穿刺(CYS)技术收集狗的尿液。研究人员记录了尿液分析和需氧尿培养的特征,并用百分比和 95% 的置信区间描述了每种收集方式下每种特征的流行率。尿培养阳性率在 SCC 和 MCD 之间没有差异(调整后的 P 值 = .099);但 CYS 的阳性率低于 SCC 和 MCD(调整后的 P 值 = .099)。
Urine Contamination Prevalence Using a Midstream Collection Device Compared with Clean Voided Collections in Dogs.
Collecting clean-caught voided urine samples is minimally invasive, but contamination occurs when urine passes through the nonsterile urethra and external genitalia. Discarding the initial urine stream may reduce these contaminants. This study hypothesized that using a midstream urine collection device would decrease bacterial and cellular contamination as compared with cleanly caught voided urine. This descriptive cross-sectional study collected urine from dogs using standard clean-caught (SCC), midstream collection device (MCD), and cystocentesis (CYS) techniques. Urinalysis and aerobic urine culture characteristics were recorded with each characteristic's prevalence described using percentages and 95% confidence intervals for each mode of collection. Positive urine culture prevalence did not differ between SCC and MCD (adjusted P value = .099); however, CYS had a lower prevalence compared with SCC and MCD (adjusted P values of <.001 [CYS versus SCC] and 0.009 [CYS versus MCD]). For other variables, there was no difference in prevalence when comparing SCC with MCD. There was no identified advantage to collecting urine using an MCD as compared with the SCC technique. Either option is a suitable alternative when CYS is not practical; however, clinicians need to interpret results cautiously because bacterial contamination is more common as compared with CYS.
