概括
中流采集尿液装置 (MCD) 没有比标准清洁捕获 (SCC) 方法在减少狗的细菌污染方面表现出任何优势. 这两种方法在获取未受污染的尿样方面都不如囊胞化 (CYS) 的可靠性.
科学领域:
- 兽医医学 兽医医学 兽医医学
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 诊断微生物学 诊断微生物学
背景情况:
- 最少侵入性尿收集是首选的,但污染是常见的.
- 在排尿期间,尿道和外部生殖器官可能会发生尿污染.
- 丢弃最初的尿液流是一种减少污染的潜在方法.
研究的目的:
- 为了比较中流尿收集装置 (MCD) 与标准清洁捕获 (SCC) 无效尿收集在减少狗的细菌和细胞污染方面的有效性.
- 通过使用MCD,SCC和囊胞化 (CYS) 技术来评估污染的流行程度.
主要方法:
- 一项描述性的横截面研究,涉及从狗身上收集尿液.
- 采用了三种尿液采集技术:标准清洁捕获 (SCC),中流采集装置 (MCD) 和囊细胞切割 (CYS).
- 进行了尿液分析和有氧尿液培养,使用百分比和置信区间描述了患病率.
主要成果:
- 在SCC和MCD之间,阳性尿培养患病率没有显著差异 (P = .099).
- 与SCC (P < .001) 和MCD (P = .009) 相比,细胞结核 (CYS) 显示出明显较低的阳性尿液培养患病率.
- 在其他尿分析变量中,在SCC和MCD之间没有发现显著差异.
结论:
- 中流收集尿液装置 (MCD) 与标准清洁捕获 (SCC) 技术相比没有显著的优势,用于减少犬尿样中的污染.
- 当 CYS 不可行时,SCC 和 MCD 都是囊细胞突变 (CYS) 的合适替代品.
- 临床医生在解释SCC和MCD的结果时应谨慎,因为与CYS相比,细菌污染的可能性更高.

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
Urine Studies I: Urinalysis
Urinalysis is a widely used diagnostic test that analyzes urine's physical, chemical, and microscopic characteristics. Healthcare providers use it to detect and monitor various health conditions, including renal disease, urinary tract infections (UTIs), diabetes, and metabolic or systemic disorders.Components of UrinalysisUrinalysis consists of three primary components: physical, chemical, and microscopic examination. Each provides unique insights into the urine sample and, by extension, the...
Imaging Studies VI: Voiding Cystourethrography and Cystography
Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
Urodynamic Studies: Uroflowmetry
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...
Urine Studies II: Urine Culture and Sensitivity Test
A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...
Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
