The objective of this study was to compare the rates of urine contamination and the frequencies of minor adverse events between the vacuum tube and injector techniques methods for the collection of sterile urine specimens.
This study was a cross-sectional study.
The sample population was composed of patients who underwent a urodynamics procedure.
This study was performed at the urodynamics unit of a rehabilitation and care center in Turkey.
Sterile urine specimens (n = 576) were collected from 144 patients using the vacuum tube technique and the injector technique; the rates of urine contamination and minor adverse events were evaluated. χ2 Statistics and Fisher exact tests were used to assess the contamination rates and frequencies of minor adverse events during the collection of sterile urine specimens.
The contamination rate of urine specimens collected using an injector was 0.9% (P > .05). The rate of minor adverse events during specimen collection was lower when using the vacuum technique than when using an injector and sterile urine container (2 vs 36 events, P < .05).
The vacuum tube technique of urine specimen collection was not superior to the injector technique in regard to contamination. The use of the vacuum tube technique for the collection of sterile urine specimens can prevent minor adverse events related to spillage/leakage of urine.
More research from multiple settings and work environments is needed to strengthen the evidence base of vacuum tube technique of sterile urine specimen collection.
本研究的目的是比较真空管技术和注射器技术在采集无菌尿液标本时的尿液污染率及轻微不良事件的发生频率。
本研究为横断面研究。
样本人群由接受尿动力学检查的患者组成。
本研究在土耳其一家康复护理中心的尿动力学科室进行。
使用真空管技术和注射器技术从144例患者中采集无菌尿液标本（n = 576）；评估尿液污染率和轻微不良事件。采用χ²检验和Fisher精确检验评估无菌尿液标本采集过程中的污染率和轻微不良事件的发生频率。
使用注射器采集的尿液标本污染率为0.9%（P > .05）。使用真空技术采集标本时的轻微不良事件发生率低于使用注射器和无菌尿液容器时（2起 vs 36起事件，P < .05）。
在污染方面，尿液标本采集的真空管技术并不优于注射器技术。使用真空管技术采集无菌尿液标本可预防与尿液溢出/渗漏相关的轻微不良事件。
需要在多种环境和工作场景下开展更多研究，以加强无菌尿液标本采集真空管技术的证据基础。
